Data of 79 rain gauge stations were selected to represent the different climatic and geomorphological domains of the state. The annual pattern was evaluated through the scale and the shape parameters of the gamma distribution and the 95th and the 5th percentiles thresholds, the latter also employed to evaluate the seasonal spatial patterns (rainy season, Oct.-Mar. and sub-humid to dry season, Apr.-Sep.). Results showed that the average precipitation was similar in P1 and P2, but S?o Paulo evolved to a pattern of increased irregularity in the rainfall distribution, with a rise of approximately 10% in the number of extremes between 1973 and 2012, especially in the very dry occurrences, and in the north and west of the state, which are the least rainy regions. Moreover, while 55% of the evaluated rain gauges recorded more extreme wet episodes in P2, 76% registered more dry extreme episodes in the same period. Some very dry or very wet events recorded after the 40-year period evaluated were discussed in terms of the associated weather patterns and their impacts on society and attested to the validity of the results found in the quantitative assessment. The qualitative analysis indicates that if the trends of more irregular distribution of rain and increase in extreme events persist, as pointed out by the gamma and percentile analyses, they would continue to bring serious effects on the natural and social systems in the state, which is the most populous and has the strongest and most diversified economy in Brazil.展开更多

Rain is the main erosive agent in the Metropolitan Region of Sao Paulo. This study characterized the erosion events caused by precipitation leveraging the accumulated daily precipitation estimate generated by the Climate Prediction Center Morphing Method (CMORPH) and integrating the surface telemetric network using the Statistical Objective Analysis method (SOAS). From the Civil Defense database, 400 events were identified in the Metropolitan region of Sao Paulo (MRSP) area between 2000 and 2013 and, of these, 3 were chosen to carry out meteorological and climatological analyses. In an initial observation, 58% of them were found to occur in summer. Two regions with the highest number of erosion events were observed, in the Serra do Mar and Serra da Cantareira. In the Serra do Mar core, the municipality of São Bernardo do Campo was the one with the greatest amount of erosion. Precipitation volumes were estimated for accumulations of 30 minutes, 1 day, 1 month, and 1 year. The results, from the 3 events, indicate accumulated precipitation in 30 minutes from 10 mm to 19.8 mm, daily from 30.8 mm to 69.5 mm, and 1 month from 369.7 mm to 742.5 mm, and 1 year (2010) from 1712.9 mm to 1961.8 mm. In these events, it was noted that there were heavy rains in December 2009 and January 2010. It was also noted that the CMORPH and SOAS identify the rain events found by the São Paulo meteorological radar. The meteorological analyzes of the events based on images from the São Paulo meteorological radar and the Meteosat-9 satellite indicate that the active precipitation systems are associated with cold fronts, instability lines, and isolated convection.展开更多

This has been a challenge for governments and managers in the development of public policies to promote healthy and quality aging. And one of the conditions for healthy aging is to assess the functional capacity and quality of life of elderly people. Objective: The aim of the present study was to evaluate the factors that influence the loss of functional capacity and the worsening of the quality of life of a representative sample of elderly people from a medium-sized city in the inner of S<span style="white-space:nowrap;">ão Paulo State, Brazil. Methodology: Questionnaires about activities of daily living (ADL), instrumental activities of daily living (IADL), Flanagan quality of life scale (FQOLS), sociodemographic and morbidities aspects were applied to the elderly people. In order to assess associated factors to functional capacity and quality of life, chi-square tests and logistic regression models were fitted including variables: gender, age group, marital status, income, education level, body mass index, abdominal circumference and some morbidities reported by the elderly people. The level of significance adopted for the statistical tests was 5%. Results: Elderly with age over 75 years old and not married had more risk to be dependent on ADL, while elderly with more than 75 years old, not married, income below one minimal wage, cardiovascular disease and be diabetic had more risk to be dependent by IADL. Already, people with excess of weight had smallest risk to be dependent by IADL, paradoxically. The elderly not married and with an income below a minimum wage had the worst quality of life. Conclusions: Population aging in Brazil is an evident factor, so it is hoped that this study will contribute to the greatest diligence on the issues of the elderly and related social problems.展开更多

This work evaluated the fertilizer-effect on the Al, Ba, Fe, Mn and Ni released in a watershed with influence of sugar cane crops in the S?o Paulo State, Brazil, namely the Monjolo Grande Stream basin. Five surface water sampling campaigns were carried out at the mouth of Monjolo Grande Stream in February, April, June, September and November 2010, characterizing the following parameters: discharge, pH, temperature, electric conductivity, dissolved oxygen and total and dissolved concentrations of Al, Ba, Fe, Mn and Ni. Approximately 99% of Al and Fe are transported annually in association with suspended sediments carried to the Monjolo Grande Stream by sheet erosion. The results also demonstrated that the increasing Al, Ba, Fe and Mn concentrations dissolved in the waters of the Monjolo Grande Stream basin in the wet season are associated to phosphate fertilizers and amendments that are used extensively in agrichemical activities. However, with the current application rates, there has been no increase in the dissolved concentrations of these metals at levels that could pose risks to human health.展开更多

Methodology: 84 isolates from several regions of Brazil (40 samples from clinical origin and 44 isolates from environmental origin) were maintained at the microorganism’s bank of the Biomedical Science Institute (ICB-USP) of the São Paulo University, in São Paulo, Brazil. This isolates was submitted fungal strains determination, DNA extraction and purification, determination of genotype by URA5 gene RFLP of CGB-positive isolates, protease and phospholipase activity and susceptibility to antifungals. Results: Of six CGB positive isolates tested by RFLP-PCR, only four presented a genomic profile consistent C. gattii species (VGII), while two other were C. neoformans (VNI and VNIII), indicating the existence of canavanine-resistante C. neoformans isolates in the culture collections. The clinical isolates secreted higher levels of phospholipase and environmental isolates but no differences were observed for the protease levels. Almost all isolates were sensible to azoles and amphotericin B. Conclusion: We point out in this research the existence of C. neoformans strains resistant to canavanine and intrinsic characteristic of C. gatti. These results demonstrate the importance to perform a detailed characterization of isolates kept in culture collections.展开更多

In view of this knowledge gap and of the need to further comprehend the importance of conserving mature forests, we surveyed the arboreal component of three little-altered forest remnants from the S?o Paulo metropolitan region (SPMR), southeastern Brazil, and compared our data with the one from other phytosociological studies performed in the region. Mature forests showed a different floristic composition from one of young forests. Overall, the former has a higher number and percentage of threatened and endemic species than the latter, and also a higher exclusivity of occurrence of threatened species. In areas up to twice as smaller, mature forests have 1.5 to 4.3 times more endemic species to the Atlantic Forest and up to 9 times more species threatened with extinction than young forests. These facts, along with the scarcity of remnants of mature forests, led us to consider such forests as hotspots within the Atlantic Forest hotspot in the SPMR, as well as to categorize them as of high relevance for conservation.展开更多

Adopting guidelines to consider managed sub regions can generate poor results. The focus of this study was to present parameters for indicators of electric energy and agricultural production to allow the formation of city groups in Sao Paulo State, Brazil, with similar electric energy consumption and rural agricultural production. The methodology was the development of indicators that characterize the electric energy consumption/agricultural production and the preparation of groups using indicators with ward of statistical method of groups. The main conclusions were the formation of six homogeneous groups with similar characteristics regarding agricultural production/consumption of electricity. The application of these groups in cities with similar characteristics would produce more satisfactory results than the division of administrative Rural Development Offices （RDO）.展开更多

This study aimed to evaluate the Escherichia coli and nutrient concentrations in the Maratuãand Crumaú rivers (Santos Estuary, Brazil) during two periods with distinct magnitudes of freshwater runoff, verifying possible relation of abiotic changes with the microbial metabolism. Water sampling was performed in October/2012 (dry season) and January/2013 (rainy season) at two points in the Crumaú river (upstream and downstream zone) and one in the Maratuãriver (downstream zone). The water subsamples were obtained for E. coli and nutrient analyses while the velocity of water flow, water level, temperature, salinity, and dissolved oxygen were measured in situ. The E. coli concentrations were under the detection limit in the Maratuãdownstream during the dry season reaching a maximum value (1.47 × 10<sup>4</sup> CFU/100mL) in the Crumaú upstream during the rainy season. E. coli presented strong positive correlation with nutrients (ammoniacal-N and phosphate), evidencing the sewage source in the Crumaú upstream shown by this association. In both periods, the low oxygen saturation (100 μmol·L<sup>-1</sup>) indicated considerable predominance of heterotrophic metabolism in the Crumaú upstream. The low dissolved oxygen values in Crumaú River are corroborated to show a low self-depuration capacity in the rainy period due to maintenance of high nutrient and E. coli at two points in the Crumaú river (upstream and downstream zone) and one in the Maratuãriver (downstream zone). Besides, these results evidenced that the tendency of the metabolism changed from autotrophic to heterotrophic under high river flow events at this studied estuarine sector located at Santos estuarine complex.展开更多

Beginning in the 1940s with the construction of the Anchieta highway, the city experienced an influx of migrants drawn by burgeoning industries, leading to unplanned urban growth and the emergence of vulnerable communities like Vila Socó. This article examines the interconnected factors—such as demographic shifts, inadequate planning, and regulatory oversight—that culminated in the devastating fire of 1984, claiming numerous lives and highlighting systemic failures. Utilizing the Haddon Matrix, this study dissects the Vila Socó incident, emphasizing the roles of human error, infrastructure integrity, and socio-economic disparities in disaster causation. By contextualizing the tragedy within Cubatão’s industrial trajectory, it underscores the urgent need for comprehensive risk assessment and proactive mitigation strategies in rapidly developing regions globally. Beyond its immediate focus, this work offers broader insights into the dynamics of industrial disasters and their socio-economic implications. As pipelines continue to play a vital role in global energy infrastructure, the lessons drawn from Vila Socó’s tragedy resonate deeply, emphasizing the imperative of robust safety protocols and accountable governance to prevent similar catastrophes in the future.展开更多

Hence, this study aimed at determining the factors that influence older people to perform physical activities. The complete IPAQ （International Physical Activity Questionnaire） was applied to a population-based sample consisting of 364 elderly persons in the city of Botucatu, SAo Paulo, Brazil. Days of physical activity performed by the older people were considered by taking into account household and leisure activities. Models for count data were fitted by including socio-demographic variables as well as those related to life satisfaction. It was shown that housework physical-activity performance is associated with female, who predominantly showed to be more active in all levels. Male seemed to be more predisposed to perform lighter recreation, sports and leisure-time physical activities, such as walking. Additionally, poor schooling showed to he decisive for not performing physical activities both at home and during leisure.展开更多

文摘The study assessed changes in rainfall variability and the frequency of extreme events (very wet and very dry) in the state of S?o Paulo, Brazil, for a 40-year period that divided into two sub-groups: 1973-1992 (P1) and 1993-2012 (P2). Data of 79 rain gauge stations were selected to represent the different climatic and geomorphological domains of the state. The annual pattern was evaluated through the scale and the shape parameters of the gamma distribution and the 95th and the 5th percentiles thresholds, the latter also employed to evaluate the seasonal spatial patterns (rainy season, Oct.-Mar. and sub-humid to dry season, Apr.-Sep.). Results showed that the average precipitation was similar in P1 and P2, but S?o Paulo evolved to a pattern of increased irregularity in the rainfall distribution, with a rise of approximately 10% in the number of extremes between 1973 and 2012, especially in the very dry occurrences, and in the north and west of the state, which are the least rainy regions. Moreover, while 55% of the evaluated rain gauges recorded more extreme wet episodes in P2, 76% registered more dry extreme episodes in the same period. Some very dry or very wet events recorded after the 40-year period evaluated were discussed in terms of the associated weather patterns and their impacts on society and attested to the validity of the results found in the quantitative assessment. The qualitative analysis indicates that if the trends of more irregular distribution of rain and increase in extreme events persist, as pointed out by the gamma and percentile analyses, they would continue to bring serious effects on the natural and social systems in the state, which is the most populous and has the strongest and most diversified economy in Brazil.
文摘Erosive processes play an important role in environmental degradation. Rain is the main erosive agent in the Metropolitan Region of Sao Paulo. This study characterized the erosion events caused by precipitation leveraging the accumulated daily precipitation estimate generated by the Climate Prediction Center Morphing Method (CMORPH) and integrating the surface telemetric network using the Statistical Objective Analysis method (SOAS). From the Civil Defense database, 400 events were identified in the Metropolitan region of Sao Paulo (MRSP) area between 2000 and 2013 and, of these, 3 were chosen to carry out meteorological and climatological analyses. In an initial observation, 58% of them were found to occur in summer. Two regions with the highest number of erosion events were observed, in the Serra do Mar and Serra da Cantareira. In the Serra do Mar core, the municipality of São Bernardo do Campo was the one with the greatest amount of erosion. Precipitation volumes were estimated for accumulations of 30 minutes, 1 day, 1 month, and 1 year. The results, from the 3 events, indicate accumulated precipitation in 30 minutes from 10 mm to 19.8 mm, daily from 30.8 mm to 69.5 mm, and 1 month from 369.7 mm to 742.5 mm, and 1 year (2010) from 1712.9 mm to 1961.8 mm. In these events, it was noted that there were heavy rains in December 2009 and January 2010. It was also noted that the CMORPH and SOAS identify the rain events found by the São Paulo meteorological radar. The meteorological analyzes of the events based on images from the São Paulo meteorological radar and the Meteosat-9 satellite indicate that the active precipitation systems are associated with cold fronts, instability lines, and isolated convection.

文摘São Paulo State has witnessed CO_(2)storage-based investigations considering the availability of suitable geologic structures and proximity to primary CO_(2)source sinks related to bioenergy and carbon capture and storage(BECCS)activities.The current study presents the hydrocarbon viability evaluations and CO_(2)storage prospects,focusing on the sandstone units of the Rio Bonito Formation.The objective is to apply petrophysical evaluations with geochemical inputs in predicting future hydrocarbon(gas)production to boost CO_(2)storage within the study location.The study used data from eleven wells with associated wireline logs(gamma ray,resistivity,density,neutron,and sonic)to predict potential hydrocarbon accumulation and fluid mobility in the investigated area.Rock samples(shale and carbonate)obtained from depths>200 m within the study location have shown bitumen presence.Organic geochemistry data of the Rio Bonito Formation shale beds suggest they are potential hydrocarbon source rocks and could have contributed to the gas accumulations within the sandstone units.Some drilled well data,e.g.,CB-1-SP and TI-1-SP,show hydrocarbon(gas)presence based on the typical resistivity and the combined neutron-density responses at depths up to 3400 m,indicating the possibility of other hydrocarbon members apart from the heavy oil(bitumen)observed from the near-surface rocks samples.From the three-dimensional(3-D)model,the free fluid indicator(FFI)is more significant towards the southwest and southeast of the area with deeper depths of occurrence,indicating portions with reasonable hydrocarbon recovery rates and good prospects for CO_(2)injection,circulation and permanent storage.However,future studies based on contemporary datasets are required to establish the hydrocarbon viability further,foster gas production events,and enhance CO_(2)storage possibilities within the region.
文摘Introduction: It is a fact that the elderly population has been increasing all around the world and also in Brazil. This has been a challenge for governments and managers in the development of public policies to promote healthy and quality aging. And one of the conditions for healthy aging is to assess the functional capacity and quality of life of elderly people. Objective: The aim of the present study was to evaluate the factors that influence the loss of functional capacity and the worsening of the quality of life of a representative sample of elderly people from a medium-sized city in the inner of S<span style="white-space:nowrap;">ão Paulo State, Brazil. Methodology: Questionnaires about activities of daily living (ADL), instrumental activities of daily living (IADL), Flanagan quality of life scale (FQOLS), sociodemographic and morbidities aspects were applied to the elderly people. In order to assess associated factors to functional capacity and quality of life, chi-square tests and logistic regression models were fitted including variables: gender, age group, marital status, income, education level, body mass index, abdominal circumference and some morbidities reported by the elderly people. The level of significance adopted for the statistical tests was 5%. Results: Elderly with age over 75 years old and not married had more risk to be dependent on ADL, while elderly with more than 75 years old, not married, income below one minimal wage, cardiovascular disease and be diabetic had more risk to be dependent by IADL. Already, people with excess of weight had smallest risk to be dependent by IADL, paradoxically. The elderly not married and with an income below a minimum wage had the worst quality of life. Conclusions: Population aging in Brazil is an evident factor, so it is hoped that this study will contribute to the greatest diligence on the issues of the elderly and related social problems.
文摘S?o Paulo State is the main sugar cane producer and these agricultural activities are carried out in predominantly sandy soils, which require large amounts of phosphate fertilizers and amendments. This work evaluated the fertilizer-effect on the Al, Ba, Fe, Mn and Ni released in a watershed with influence of sugar cane crops in the S?o Paulo State, Brazil, namely the Monjolo Grande Stream basin. Five surface water sampling campaigns were carried out at the mouth of Monjolo Grande Stream in February, April, June, September and November 2010, characterizing the following parameters: discharge, pH, temperature, electric conductivity, dissolved oxygen and total and dissolved concentrations of Al, Ba, Fe, Mn and Ni. Approximately 99% of Al and Fe are transported annually in association with suspended sediments carried to the Monjolo Grande Stream by sheet erosion. The results also demonstrated that the increasing Al, Ba, Fe and Mn concentrations dissolved in the waters of the Monjolo Grande Stream basin in the wet season are associated to phosphate fertilizers and amendments that are used extensively in agrichemical activities. However, with the current application rates, there has been no increase in the dissolved concentrations of these metals at levels that could pose risks to human health.
文摘Objective: As isolates of Cryptococcus are frequently kept collection stocks in institutions, sometimes without proper characterization, we sought to determine the genotype profiles, protease and phospholipase activities “in vitro” and the susceptibility testing for azoles and amphotericin B. Methodology: 84 isolates from several regions of Brazil (40 samples from clinical origin and 44 isolates from environmental origin) were maintained at the microorganism’s bank of the Biomedical Science Institute (ICB-USP) of the São Paulo University, in São Paulo, Brazil. This isolates was submitted fungal strains determination, DNA extraction and purification, determination of genotype by URA5 gene RFLP of CGB-positive isolates, protease and phospholipase activity and susceptibility to antifungals. Results: Of six CGB positive isolates tested by RFLP-PCR, only four presented a genomic profile consistent C. gattii species (VGII), while two other were C. neoformans (VNI and VNIII), indicating the existence of canavanine-resistante C. neoformans isolates in the culture collections. The clinical isolates secreted higher levels of phospholipase and environmental isolates but no differences were observed for the protease levels. Almost all isolates were sensible to azoles and amphotericin B. Conclusion: We point out in this research the existence of C. neoformans strains resistant to canavanine and intrinsic characteristic of C. gatti. These results demonstrate the importance to perform a detailed characterization of isolates kept in culture collections.
文摘The Atlantic Forest is among the 35 hotspots on the planet, and yet few floristic or structural studies have been conducted on mature forest fragments of that biome in Brazil. In view of this knowledge gap and of the need to further comprehend the importance of conserving mature forests, we surveyed the arboreal component of three little-altered forest remnants from the S?o Paulo metropolitan region (SPMR), southeastern Brazil, and compared our data with the one from other phytosociological studies performed in the region. Mature forests showed a different floristic composition from one of young forests. Overall, the former has a higher number and percentage of threatened and endemic species than the latter, and also a higher exclusivity of occurrence of threatened species. In areas up to twice as smaller, mature forests have 1.5 to 4.3 times more endemic species to the Atlantic Forest and up to 9 times more species threatened with extinction than young forests. These facts, along with the scarcity of remnants of mature forests, led us to consider such forests as hotspots within the Atlantic Forest hotspot in the SPMR, as well as to categorize them as of high relevance for conservation.
文摘The issue in this matter is that rules for use of electricity in rural areas are limited to the provision of inputs. Adopting guidelines to consider managed sub regions can generate poor results. The focus of this study was to present parameters for indicators of electric energy and agricultural production to allow the formation of city groups in Sao Paulo State, Brazil, with similar electric energy consumption and rural agricultural production. The methodology was the development of indicators that characterize the electric energy consumption/agricultural production and the preparation of groups using indicators with ward of statistical method of groups. The main conclusions were the formation of six homogeneous groups with similar characteristics regarding agricultural production/consumption of electricity. The application of these groups in cities with similar characteristics would produce more satisfactory results than the division of administrative Rural Development Offices （RDO）.
文摘Sewage introduction into rivers has altered the physical and chemical properties of waters and also the microbial metabolism. This study aimed to evaluate the Escherichia coli and nutrient concentrations in the Maratuãand Crumaú rivers (Santos Estuary, Brazil) during two periods with distinct magnitudes of freshwater runoff, verifying possible relation of abiotic changes with the microbial metabolism. Water sampling was performed in October/2012 (dry season) and January/2013 (rainy season) at two points in the Crumaú river (upstream and downstream zone) and one in the Maratuãriver (downstream zone). The water subsamples were obtained for E. coli and nutrient analyses while the velocity of water flow, water level, temperature, salinity, and dissolved oxygen were measured in situ. The E. coli concentrations were under the detection limit in the Maratuãdownstream during the dry season reaching a maximum value (1.47 × 10<sup>4</sup> CFU/100mL) in the Crumaú upstream during the rainy season. E. coli presented strong positive correlation with nutrients (ammoniacal-N and phosphate), evidencing the sewage source in the Crumaú upstream shown by this association. In both periods, the low oxygen saturation (100 μmol·L<sup>-1</sup>) indicated considerable predominance of heterotrophic metabolism in the Crumaú upstream. The low dissolved oxygen values in Crumaú River are corroborated to show a low self-depuration capacity in the rainy period due to maintenance of high nutrient and E. coli at two points in the Crumaú river (upstream and downstream zone) and one in the Maratuãriver (downstream zone). Besides, these results evidenced that the tendency of the metabolism changed from autotrophic to heterotrophic under high river flow events at this studied estuarine sector located at Santos estuarine complex.
文摘The tragedy of Vila Socó epitomizes the socio-environmental repercussions of rapid industrialization in Cubatão. Beginning in the 1940s with the construction of the Anchieta highway, the city experienced an influx of migrants drawn by burgeoning industries, leading to unplanned urban growth and the emergence of vulnerable communities like Vila Socó. This article examines the interconnected factors—such as demographic shifts, inadequate planning, and regulatory oversight—that culminated in the devastating fire of 1984, claiming numerous lives and highlighting systemic failures. Utilizing the Haddon Matrix, this study dissects the Vila Socó incident, emphasizing the roles of human error, infrastructure integrity, and socio-economic disparities in disaster causation. By contextualizing the tragedy within Cubatão’s industrial trajectory, it underscores the urgent need for comprehensive risk assessment and proactive mitigation strategies in rapidly developing regions globally. Beyond its immediate focus, this work offers broader insights into the dynamics of industrial disasters and their socio-economic implications. As pipelines continue to play a vital role in global energy infrastructure, the lessons drawn from Vila Socó’s tragedy resonate deeply, emphasizing the imperative of robust safety protocols and accountable governance to prevent similar catastrophes in the future.
文摘Introduction: Currently it is very common that the search for diagnosis and treatment for curing diseases can cause vertigo or dizziness. Objective: This study sought to characterize the profile of patients seen in the clinic for vestibular rehabilitation in a tertiary hospital in the last 10 years. Methods: Survey questionnaires of patients with dizziness. Results: The prevalence of treated subjects was female 65.3% (N = 439). The average age was 54.9 years old. Dizziness type roundabout was more prevalent 33.04% (N = 222). Tinnitus occurred in 58.33% of the population. The time of most observed dizziness was less than 5 years 70.68% (N = 475). Neurovegetative symptoms appeared in 63.98% (N = 430) of the population. The bilateral normal hearing was more standard 35.26% (N = 237). The topographic diagnosis of peripheral origin was the most usual 65.47% (N = 440). Conclusion: The peripheral otoneurologic involvement was more prevalent in this population, affecting more women at an average age of 54.9 years old. The most prevalent symptoms were vertigo, nausea, tachycardia, sweating, vomiting and tinnitus, characterizing the peripheral vestibular impairment. The time of dizziness was less than five years. Audiological standard normal curve was predominant and the symptom of tinnitus was the most reported. The most prevalent comorbidity was Hypertension.
文摘The collection and proper disposal of MSW(Municipal Solid Waste)is one of the biggest challenges faced by Brazilian public managers.Dry recyclable waste represents about 33.6%of the gravimetric composition of MSW,with a tendency to increase in the next few years,due to the increasing consumption of processed products,with short life cycles and excess packaging.The inadequate management of these residues results in a series of social,environmental and economic problems.In recent years,there has been a great advance in Brazilian laws,assigning responsibilities and regulating waste management in the country,optimizing the use of infrastructure and human and financial resources.Scarce resources and insufficient infrastructure demand actions based on a lot of planning.One of the main limiting factors for the planning and development of public policies for the sector is the lack of reliable data and information on the generation and management of waste,that allow the creation of future scenarios and the definition of adequate strategies for minimization,valorization of waste and final disposal of waste that no longer can be processed.Thus,this work sought to analyze the current situation of selective waste collection and recycling cooperatives in 211 municipalities in the State of São Paulo,evaluating the issues and opportunities for the applicability of Law n.12,305/2010,Brazilian PNRS(in Portuguese)(National Policy of Solid Waste)in the management of this waste in small,medium and large cities.A bibliographic research was carried out on the panorama of solid waste management in Brazil and in the State of São Paulo,as well as a contextualization on selective waste collection and recycling cooperatives.Following that,data from 211 municipalities taking part in the survey Solid Waste Management—Municipalities of the State of São Paulo were analyzed,focusing on answers that correlated with the topics covered in this research.For this work,questions were used in order to obtain a basic overview of solid waste management in the municipalities,identifying the characteristics of selective waste collection and recycling cooperatives in the municipalities and to verify the similarity,benefits and difficulties of selective waste collection and waste cooperatives in the municipalities studied.After tabulating and analyzing the data,a matrix was prepared to compare the results obtained in relation to selective waste collection and recycling cooperatives and the guidelines of the PNRS(National Solid Waste Policy)in urban environmental management,which allowed the conclusion that all municipalities participating in the research have a good understanding of solid waste management practices,as well as seek to comply with the guidelines of the PNRS.However,the results of this matrix indicated that there are important points that need to be considered in the planning of actions for a better management of recyclable waste,such as the implementation of inter-municipal consortiums in the management of solid waste,investment in environmental education,stimulation to create recycling cooperatives and adoption of social inclusion regulations for informal waste collectors.
文摘Physical activity has been scientifically discussed as fundamental in the process of healthy ageing. Hence, this study aimed at determining the factors that influence older people to perform physical activities. The complete IPAQ （International Physical Activity Questionnaire） was applied to a population-based sample consisting of 364 elderly persons in the city of Botucatu, SAo Paulo, Brazil. Days of physical activity performed by the older people were considered by taking into account household and leisure activities. Models for count data were fitted by including socio-demographic variables as well as those related to life satisfaction. It was shown that housework physical-activity performance is associated with female, who predominantly showed to be more active in all levels. Male seemed to be more predisposed to perform lighter recreation, sports and leisure-time physical activities, such as walking. Additionally, poor schooling showed to he decisive for not performing physical activities both at home and during leisure.
文摘It was in the 1980s that research on somatostatin(SST)in Alzheimer’s disease(AD)truly gained traction,demonstrating consistent colocalization with amyloid-β(Aβ),along with massive SST/SST cell losses(Almeida,2024).Although the field already had some grasp over the neuroendocrine and hypothalamic functions of the peptide,very little was known about the GABAergic interneurons(SST-INs)that synthesize it in cortical/hippocampal regions.Quite excitingly,over 40 years later,research has grown effervescent.
文摘Rheumatoid arthritis(RA)is a chronic systemic autoimmune disease that extends beyond joint inflammation,affecting pulmonary and metabolic pathways.Interstitial lung disease(ILD)is one of its most serious extra-articular complications,while type 2 diabetes mellitus(T2DM)frequently coexists with RA and may exacerbate inflammatory and fibrotic processes.This editorial discusses the study by Sutton et al,the largest population-based analysis to date exploring the link between T2DM and ILD in patients with RA,and reflects on its mechanistic and clinical implications.In a nationwide cohort of more than 120000 hospitalized RA patients,Sutton et al demonstrated that the coexistence of T2DM nearly doubles the odds of developing ILD(odds ratio=2.02;95%confidence interval:1.84-2.22),with additional increases in pulmonary hypertension,pneumothorax,and length of stay.These findings reinforce the concept of a metabolic-pulmonary-autoimmune axis,in which chronic inflammation promotes insulin resistance and metabolic dysfunction,while hyperglycaemia and advanced glycation end-products amplify oxidative stress and fibrogenesis.This reciprocal interaction may induce a self-perpetuating cycle of“metaflammation”,fibrosis,and organ damage.Conclusion:Recognizing diabetes as a silent amplifier of RA-associated ILD redefines the interface between rheumatology,pulmonology,and endocrinology.Early detection and integrated management of metabolic and pulmonary comorbidities should be prioritized,while future studies must determine whether optimizing glycemic control can attenuate pulmonary fibrosis and improve longterm outcomes.

文摘The intricate landscape of neurodegenerative diseases complicates the search for effective therapeutic approaches.Photoreceptor degeneration,the common endpoint in various retinal diseases,including retinitis pigmentosa and age-related macular degeneration,leads to vision loss or blindness.While primary cell death is driven by genetic mutations,oxidative stress,and neuroinflammation,additional mechanisms contribute to disease progression.In retinitis pigmentosa,a multitude of genetic alterations can trigger the degeneration of photoreceptors,while other retinopathies,such as agerelated macular degeneration,are initiated by combinations of environmental factors,such as diet,smoking,and hypertension,with genetic predispositions.Nutraceutical therapies,which blend the principles of nutrition and pharmaceuticals,aim to harness the health benefits of bioactive compounds for therapeutic applications.These compounds generally possess multi-target effects.Polyphenols and flavonoids,secondary plant metabolites abundant in plant-based foods,are known for their antioxidant,neuroprotective,and anti-inflammatory properties.This review focuses on the potential of polyphenols and flavonoids as nutraceuticals to treat neurodegenerative diseases such as retinitis pigmentosa.Furthermore,the importance of developing reliable delivery methods to enhance the bioavailability and therapeutic efficacy of these compounds will be discussed.By combining nutraceuticals with other emerging therapies,such as genetic and cell-based treatments,it is possible to offer a more comprehensive approach to treating retinal degenerative diseases.These advancements could lead to a viable and accessible option,improving the quality of life for patients with retinal diseases.
文摘Recently,the restoration work of Vila Itororó-an architectural complex in central São Paulo,built around the 1920s,has been carried out,enabling applied field research for restoration as well as for historical perspective of the social and cultural development that took place at Vila Itororó.Alongside the restoration work,a cultural centre has been installed on the site,embracing the opportunities of creating a new agenda for Vila Itororówith the community while the restoration takes place.Through this,Vila Itororóhas been able to bring the discussion and practise of restoration closer to the civil society,reaching a public beyond the academic circles.The rich environment produced by these efforts has allowed for an outlet of publications and discussions regarding issues that range from architectural prospection to the role that heritage can play with our society in the city of the 21st century.This paper intends to present some of these discussions,their origins,insights and other findings that this experience has fostered.
文摘This paper studies the context of the central area contiguous with the iron bed of medium-sized cities of the northwest region of São Paulo,in Brazil,namely:Presidente Prudente,Araçatuba,Birigüi,São Josédo Rio Preto and Marilia.Not surprisingly,the ancient boundaries of railway lines crossing the countryside regions.These urban centers were developed by the expansion of the railway,but with the deactivation of the rail transport,its core areas went into obsolescence and deterioration process and,more recently,are suffering processes of modernization and productive restructuring.At the same time,amid the industrial landscapes and decaying railroad heritage,there are situations and dweller types able to reveal some imaginary,capable of triggering:surprises,dilemmas and entanglements in the analysis of urban composition,the modernization process and its consequent deterioration.Therefore,from the marginal uses present in each city of the northwestern country towns of São Paulo,we try explain a poltical and critical point of view of these urban areas.Thus,the marginal architecture is not only the expression of subaltern subjectivities,reflecting the complexities present in emblematic areas of public importance,affected by degradation processes,but also,the attempt to define a concept strategy:a destabilizing way of reading places filled with meaning,in the counterculture of the hegemonic space to make experimental projects.

文摘The focus of this study was to investigate the wide use of Eucalyptus spp.,an exotic plant with high allelopathic ability,in the reforestation programs of urban parks in São Paulo City,Brazil,over the last century.To understand the implications of using Eucalyptus spp.in the city’s parks,this study aimed to compare nutrient cycling and litter decomposition between a mixed composition of litter(i.e.,native and exotic species)and the litter of a single species(i.e.,Eucalyptus).To accomplish this,newly deciduous leaves were collected from two native and two exotic species that are commonly used in the afforestation of São Paulo as well as from Eucalyptus spp.The mixed composition of litter yielded a higher dry mass loss and return of macro-and micronutrients to the forest floor.The decomposition constant(k)values were 0.00322 and 0.00207 g g^(−1) day^(−1) for the mixed composition and Eucalyptus spp.,respectively.The time required for decomposition of 50 and 95%of deciduous material was 215 and 931 days,respectively,and for the mixed litterfall 334 and 1449 days,respectively,for Eucalyptus spp.Therefore,the mixed litter exhibited greater dry mass loss and nutrient cycling in an urban forest of São Paulo City,since dry mass losses as well as speed and amount of nutrients returned to the forest floor were relatively higher compared to Eucalyptus spp.Nutrient cycling via Eucalyptus spp.litter was less efficient than mixed composition of litter,demonstrating that reforestation programs carried out in the twentieth century using only one species may have had little success.The results of this work emphasize the fact that in urban reforestation programs the City of São Paulo must consider the environmental and biogeographic characteristics of the species employed and use high levels of biodiversity,since the city lies in a megadiverse biome.
