Active fractions were separated and characterized and, in the case of O. crenata, two phenolic compounds, verbascoside and is overbascoside, were quantitatively extracted, purified and characterized. These compounds proved to be effective in reducing the growth of some important fungi responsible for the decay of fresh fruit and vegetables in postharvest. Verbascoside showed significant activity against Penicillium italicum, fairly inhibited Monilinia laxa, P. expansum, and Aspergillus carbonarius, and showed little activity against Botrytis cinerea, M. fructicola and P. digitatum. Isoverbascoside completely inhibited B. cinerea, P. digitatum, P. italicum, and P. expansum;it fairly inhibited M. laxa and A. carbonarius;while it showed to be less effective against M. fructicola. The obtained results support the possible use of some wild edible plants as a source of phenolic substances for the postharvest biological control of fresh fruit and vegetable rots.展开更多

Det...Every region around the globe has its unique climatic conditions which are set based on different orographic constant and atmospheric dynamic features. These features posses’ variability on different time scales. Determining the local sea level change based on terrestrial non-tidal, short-term variability is complicated. Some internal mechanisms of ocean are also taking place along with the external physical ones. We show that variability at Sindh-Baluchistan coastal belt can be greatly explained via dimensional indices of the position and intensity of the atmospheric center of action (COAs). This technique has already proved its usefulness at number of location especially in Northern Atlantic. It takes into account the changes in the atmospheric pressure which is exerted on the sea surface influencing the variability in sea level on seasonal scale and on inter-annual basis. As warming causes thermal expansion of water it also causes changes in atmospheric circulation. Both of these processes affect the sea level variability on their respective time scales. Atmospheric being the quicker one of the two to pass on the effect is also more influential to explain the variability in local sea level. In this attempt the COA approach is used to assess the impact of low pressure on local sea levels.展开更多

Our aim was to compare women with episiotomy, to women with an intact perineum, 3 months after delivery, regarding several sexual variables, namely: sexual desire, arousal, orgasm, pain, sexual satisfaction and sexual function. Methods: An exploratory, descriptive and quantitative study using a non-probabilistic, convenience sample of 147 Portuguese women, of which 54 belonged to a control group, was performed. The groups were not significantly different regarding socio-demographic aspects. Three instruments were used: the Female Sexual Function Index, a Socio-demographic and Clinical Questionnaire and the Female Sexual Function Questionnaire. Results: Most women mentioned a moderate level of sexual interest. Women with episiotomy present higher pain intensity, less sexual satisfaction, greater changes regarding the orgasm’s duration and intensity, lower levels of sexual arousal and total sexual function, than women with intact perineum. Discussion: We found no significant differences between women with episiotomy and women with an intact perineum in most variables. However, women with episiotomy presented higher levels of pain and a lower sexual satisfaction, being these significant differences.展开更多

To this propose, we used the Maslach Burnout Inventory, which is the most used psychometric inventory to measure burnout in different professional context (Students, Teachers, Police, Doctors, Nurses, etc…). The version of the MBI used was the MBI-Student Survey (MBI-SS). This inventory is composed of three key dimensions: Exhaustion, Cynicism and Professional Efficacy. The two first dimensions—which have positive formulated items—are moderate to strong positive correlated, and show moderate to strong negative correlations with the 3rd dimension—which has negative formulated items. We tested the hypothesis that, in college students, formulating the 3rd dimension of burnout as Inefficacy (reverting the negatively worded items in the Efficacy dimension) improves the correlation of the 3rd dimension with the other two dimensions, improves its internal consistency, and the overall MBI-SS’ construct validity and reliability. Confirmatory factor analysis results, estimated by Maximum Likelihood, revealed adequate factorial fit for both forms of the MBI-SS (with Efficacy) vs. the MBI-SSi (with Inefficacy). Also both forms showed adequate convergent and discriminant related validity. However, reliability and convergent validity were higher for the MBI-SSi. There were also stronger (positive) correlations between the 3 factors in MBI-SSi than the ones observed in MBI-SS. Results show that positively rewording of the 3rd dimension of the MBI-SS improves its validity and reliability. We therefore propose that the 3rd dimension of the MBI-SS should be named Professional Inefficacy and its items should be positively worded.展开更多

Its assessment should not be limited to the intensity of perceived pain but should also consider the psychosocial and behavioral aspects involved. Objective: The aims of this study were to adapt and validate the Multidimensional Pain Inventory (MPI) for orthodontic patients, and present a proposal to calculate an overall score of the pain-related aspects and compare these scores with the usual methodology used. Methods: Face validity of the MPI was estimated and orthodontic version (MPI-Orthodontic) was developed. Factorial validity was evaluated by confirmatory analysis. Convergent and discriminant validity and reliability were estimated. The fit of Second-Order Hierarchical Models was estimated. Concurrent validity of MPI-Orthodontic was evaluated against the Visual Analogue Scale. Invariance of the factorial models was evaluated for independent samples and according to sex and age. Overall score was calculated using the matrix of regression weights and compared to simple arithmetic mean. Results: 507 individuals (63.3% women;age: 26.32 (SD = 11.70) years) participated. For the fit of Part I (psychosocial aspects) of the MPI-Orthodontic, it added correlation between two items and excluded one item;for Part II (behavioral aspects) two items were excluded. The models presented adequate fit to the sample. Reliability was adequate. MPI-Orthodontic presented invariance for independent samples and adequate concurrent and divergent validity. Score obtained with the simple arithmetic mean was overestimated for Part I and underestimated for Part II. Conclusion: MPI-Orthodontic was valid, reliable and invariant for the evaluation of the orthodontic pain. It is recommended to calculate overall weighted scores for pain assessment.展开更多

Methods Participants comprised 1893 families from the INfancia y Medio Ambiente(INMA)project.Information was collected on the presence of(1)any pet,(2)dogs,(3)cats,(4)birds or(5)other animals.Pet ownership was categorized as never,always,only at age 1 and only at age 4-5.Internalizing and externalizing problems were measured at ages 7-8 years through the Strengths and Difficulties Questionnaire,a Likert questionnaire on children's behavioural and emotional symptoms.Negative binomial regression models and Tukey's multiple comparison tests were used to analyse data sets.Five sensitivity analyses were performed. Results Families that always owned a pet made up 24.4%of the sample.In addition,11.5%,4.5%,3.8%and 17.6%of the families owned a dog,cat,bird or other animal,respectively.The median(P25-P75)for internalizing problems was 3(1-5)and 5(3-8)for externalizing problems.Owning a cat only at age 4-5 increased mental health problems:relative rate ratio(RRR)[95%confidence interval(CI)]1.37(1.05-1.79)for internalizing and 1.26(1.02-1.56)for externalizing.Always having other animals was a protective factor for internalizing problems with an RRR of 0.80(0.66-0.96).These associations remained after multiple comparison testing and sensitivity analyses. Conclusion Owning a cat only at 4-5 years of age was linked to more internalizing and externalizing problems,whereas always having other animals was a protective factor against internalizing problems.展开更多

文摘Cadmium(Cd)is a toxic trace metal that occurs naturally in agricultural soils and can accumulate in the edible parts of crops,notably in cereal grains.This study investigated the extent to which sulfur(S)fertilization increases the availability of Cd in a calcareous(Calc)and a non-calcareous(Ncalc)soil.Changes in Cd availability and speciation were monitored over a 21-d incubation period,along with changes in pH and the concentrations of sulfate,nitrate,calcium,magnesium,aluminum(Al),manganese(Mn),and nickel(Ni)in the potassium nitrate(KNO_(3))extracts,after the addition at agronomic rates of three forms of S fertilizers:elemental S(S(0)),potassium sulfate(K_(2)SO_(4)),and ammonium sulfate((NH_(4))_(2)SO_(4)).Elemental S did not increase the Cd concentration in the KNO_(3)extracts of either soil due to its too limited oxidation to sulfates.The two sulfate fertilizers had contrasting effects on Cd concentration depending on the nature of the counter cation(K^(+)or NH_(4)^(+)).While K_(2)SO_(4)caused almost no change in Cd concentration in either soil,(NH_(4))_(2)SO_(4)increased Cd concentration in both soils.The nitrification of NH_(4)^(+)reduced soil pH,thereby increasing the concentrations of Cd,Al,Mn,and Ni in the Ncalc soil over time,as evidenced by the strong negative correlations between soil pH and the concentrations of these four elements in the KNO3 extract after 21 d.In the Calc soil,the mechanism of Cd concentration increase after(NH_(4))_(2)SO_(4)addition was more difficult to understand and could result from the proton-mediated alteration of Cd-bearing phases such as carbonates,following ammonia(NH_(3))volatilization.The relevance of these results for the S fertilization of cereals in Cd-contaminated soils is discussed.

文摘Exercise has long been known for its active role in improving physical fitness and sustaining health.Regular moderate-intensity exercise improves all aspects of human health and is widely accepted as a preventative and therapeutic strategy for various diseases.It is well-documented that exercise maintains and restores homeostasis at the organismal,tissue,cellular,and molecular levels to stimulate positive physiological adaptations that consequently protect against various pathological conditions.Here we mainly summarize how moderate-intensity exercise affects the major hallmarks of health,including the integrity of barriers,containment of local perturbations,recycling and turnover,integration of circuitries,rhythmic oscillations,homeostatic resilience,hormetic regulation,as well as repair and regeneration.Furthermore,we summarize the current understanding of the mechanisms responsible for beneficial adaptations in response to exercise.This review aimed at providing a comprehensive summary of the vital biological mechanisms through which moderate-intensity exercise maintains health and opens a window for its application in other health interventions.We hope that continuing investigation in this field will further increase our understanding of the processes involved in the positive role of moderate-intensity exercise and thus get us closer to the identification of new therapeutics that improve quality of life.

We show that variability at Sindh-Baluchistan coastal belt can be greatly explained via dimensional indices of the position and intensity of the atmospheric center of action (COAs). This technique has already proved its usefulness at number of location especially in Northern Atlantic. It takes into account the changes in the atmospheric pressure which is exerted on the sea surface influencing the variability in sea level on seasonal scale and on inter-annual basis. As warming causes thermal expansion of water it also causes changes in atmospheric circulation. Both of these processes affect the sea level variability on their respective time scales. Atmospheric being the quicker one of the two to pass on the effect is also more influential to explain the variability in local sea level. In this attempt the COA approach is used to assess the impact of low pressure on local sea levels.

文摘A headspace solid-phase microextraction-gas chromatography-mass spectrometry(HS-SPME/GC-MS)method was used to study the volatile organic compounds(VOCs)associated with the differential immune response of tomato plants infected with the recombinant strain of potato virus Y(PVY^(C)-to),necrogenic to tomato.Analysis was carried out in UC82(UC),a virus susceptible tomato variety,comparing the same UC plants grafted or not onto a virus tolerant tomato ecotype,Manduria(Ma);the three types of samples used for the GC-MS analysis were mock-inoculated UC/Ma plants,UC/Ma+PVY^(C)-to and UC+PVY^(C)-to plants;the VOCs obtained were 111.Results from symptomatic PVY^(C)-to-infected UC plants showed a VOCs composition enriched in alcohols,fatty acid derivates,benzenoids,and salicylic acid derivatives,while in mock-inoculated UC/Ma plants VOCs were mainly characterized by methyl ester compounds.The VOC profile was in line with RNAseq data analyses,denoting that PVY^(C)-to viral RNA accumulation and disease symptoms induce the specific transcriptional activation of genes involved in VOCs biosynthesis.Furthermore,principal component analysis highlighted that VOCs of PVY^(C)-to-infected and mock-inoculated grafted plants were much closer each other than that of symptomatic PVY^(C)-to-infected non-grafted UC plants.These results suggest that VOCs profiles of tomato plants are related to the viral RNA accumulation,disease intensity and graft-derived tolerance to PVY^(C)-to infection.

文摘1.Introduction Regular exercise induces changes in the overall diversity and in the relative abundance of certain gut microbiota phyla and families in humans1,2 and in animal models.3,4 This relationship has attracted a great deal of interest because it is one of the mechanisms involved in the health benefits of regular exercise3 that could also influence performance.5 A recent publication by Scheiman et al.
文摘It is estimated that approximately one in ten people over the age of 80 may suffer from cardiac amyloidosis(CA),a disease in which various aging-related factors,such as increased oxidative stress,can promote abnormal protein folding and the formation of amyloid deposits in the heart.Over the long term,this tends to impair cardiac function,increasing the risk of developing cardiac conduction disorders,atrial fibrillation,thromboembolic events,heart failure(HF),and/or ventricular dysfunction.^([1,2])
文摘Objective: Despite the fact that a restrictive use of episiotomy has proven to be beneficial, it continues to be widely used in vaginal births. Our aim was to compare women with episiotomy, to women with an intact perineum, 3 months after delivery, regarding several sexual variables, namely: sexual desire, arousal, orgasm, pain, sexual satisfaction and sexual function. Methods: An exploratory, descriptive and quantitative study using a non-probabilistic, convenience sample of 147 Portuguese women, of which 54 belonged to a control group, was performed. The groups were not significantly different regarding socio-demographic aspects. Three instruments were used: the Female Sexual Function Index, a Socio-demographic and Clinical Questionnaire and the Female Sexual Function Questionnaire. Results: Most women mentioned a moderate level of sexual interest. Women with episiotomy present higher pain intensity, less sexual satisfaction, greater changes regarding the orgasm’s duration and intensity, lower levels of sexual arousal and total sexual function, than women with intact perineum. Discussion: We found no significant differences between women with episiotomy and women with an intact perineum in most variables. However, women with episiotomy presented higher levels of pain and a lower sexual satisfaction, being these significant differences.
文摘This study evaluated the effect of item inversion on the construct validity and reliability of psychometric scales and proposed a theoretical framework for the evaluation of the psychometric properties of data gathered with psychometric instruments. To this propose, we used the Maslach Burnout Inventory, which is the most used psychometric inventory to measure burnout in different professional context (Students, Teachers, Police, Doctors, Nurses, etc…). The version of the MBI used was the MBI-Student Survey (MBI-SS). This inventory is composed of three key dimensions: Exhaustion, Cynicism and Professional Efficacy. The two first dimensions—which have positive formulated items—are moderate to strong positive correlated, and show moderate to strong negative correlations with the 3rd dimension—which has negative formulated items. We tested the hypothesis that, in college students, formulating the 3rd dimension of burnout as Inefficacy (reverting the negatively worded items in the Efficacy dimension) improves the correlation of the 3rd dimension with the other two dimensions, improves its internal consistency, and the overall MBI-SS’ construct validity and reliability. Confirmatory factor analysis results, estimated by Maximum Likelihood, revealed adequate factorial fit for both forms of the MBI-SS (with Efficacy) vs. the MBI-SSi (with Inefficacy). Also both forms showed adequate convergent and discriminant related validity. However, reliability and convergent validity were higher for the MBI-SSi. There were also stronger (positive) correlations between the 3 factors in MBI-SSi than the ones observed in MBI-SS. Results show that positively rewording of the 3rd dimension of the MBI-SS improves its validity and reliability. We therefore propose that the 3rd dimension of the MBI-SS should be named Professional Inefficacy and its items should be positively worded.

文摘BACKGROUNDPatients with advanced gastrointestinal cancer must cope with the negative effects of cancer and complications.AIM To evaluate psychological distress,quality of life,and coping strategies in patients with advanced colorectal cancer compared to non-colorectal cancer based on sex.METHODS A prospective,transversal,multicenter study was conducted in 203 patients;101(50%)had a colorectal and 102(50%)had digestive,non-colorectal advanced cancer.Participants completed questionnaires evaluating psychological distress(Brief Symptom Inventory-18),quality of life(EORTC QLQ-C30),and coping strategies(Mini-Mental Adjustment to Cancer)before starting systemic cancer treatment.RESULTS The study included 42.4%women.Women exhibited more depressive symptoms,anxiety,functional limitations,and anxious preoccupation than men.Patients with non-colorectal digestive cancer and women showed more somatization and physical symptoms than subjects with colorectal cancer and men.Men with colorectal cancer reported the best health status.CONCLUSION The degree of disease acceptance in gastrointestinal malignancies may depend on sex and location of the primary digestive neoplasm.Future interventions should specifically address sex and tumor site differences in individuals with advanced digestive cancer.
文摘Background: Pain perception may result from orthodontic treatment and should be considered in clinical management. Its assessment should not be limited to the intensity of perceived pain but should also consider the psychosocial and behavioral aspects involved. Objective: The aims of this study were to adapt and validate the Multidimensional Pain Inventory (MPI) for orthodontic patients, and present a proposal to calculate an overall score of the pain-related aspects and compare these scores with the usual methodology used. Methods: Face validity of the MPI was estimated and orthodontic version (MPI-Orthodontic) was developed. Factorial validity was evaluated by confirmatory analysis. Convergent and discriminant validity and reliability were estimated. The fit of Second-Order Hierarchical Models was estimated. Concurrent validity of MPI-Orthodontic was evaluated against the Visual Analogue Scale. Invariance of the factorial models was evaluated for independent samples and according to sex and age. Overall score was calculated using the matrix of regression weights and compared to simple arithmetic mean. Results: 507 individuals (63.3% women;age: 26.32 (SD = 11.70) years) participated. For the fit of Part I (psychosocial aspects) of the MPI-Orthodontic, it added correlation between two items and excluded one item;for Part II (behavioral aspects) two items were excluded. The models presented adequate fit to the sample. Reliability was adequate. MPI-Orthodontic presented invariance for independent samples and adequate concurrent and divergent validity. Score obtained with the simple arithmetic mean was overestimated for Part I and underestimated for Part II. Conclusion: MPI-Orthodontic was valid, reliable and invariant for the evaluation of the orthodontic pain. It is recommended to calculate overall weighted scores for pain assessment.

文摘Background We aimed to explore associations between the presence of pets at one and 4-5 years of age with internalizing and externalizing problems at 7-8 years. Methods Participants comprised 1893 families from the INfancia y Medio Ambiente(INMA)project.Information was collected on the presence of(1)any pet,(2)dogs,(3)cats,(4)birds or(5)other animals.Pet ownership was categorized as never,always,only at age 1 and only at age 4-5.Internalizing and externalizing problems were measured at ages 7-8 years through the Strengths and Difficulties Questionnaire,a Likert questionnaire on children's behavioural and emotional symptoms.Negative binomial regression models and Tukey's multiple comparison tests were used to analyse data sets.Five sensitivity analyses were performed. Results Families that always owned a pet made up 24.4%of the sample.In addition,11.5%,4.5%,3.8%and 17.6%of the families owned a dog,cat,bird or other animal,respectively.The median(P25-P75)for internalizing problems was 3(1-5)and 5(3-8)for externalizing problems.Owning a cat only at age 4-5 increased mental health problems:relative rate ratio(RRR)[95%confidence interval(CI)]1.37(1.05-1.79)for internalizing and 1.26(1.02-1.56)for externalizing.Always having other animals was a protective factor for internalizing problems with an RRR of 0.80(0.66-0.96).These associations remained after multiple comparison testing and sensitivity analyses. Conclusion Owning a cat only at 4-5 years of age was linked to more internalizing and externalizing problems,whereas always having other animals was a protective factor against internalizing problems.

文摘Aims Invasive species,which recently expanded,may help understand how climatic niche can shift at the time scale of the current global change.Here,we address the climatic niche shift of an invasive shrub(common gorse,Ulex europaeus)at the world and regional scales to assess how it could contribute to increasing invasibility.Methods Based on a 28187 occurrences database,we used a combination of 9 species distribution models(SDM)to assess regional climatic niche from both the native range(Western Europe)and the introduced range in different parts of the world(North-West America,South America,North Europe,Australia and New Zealand).Important Findings Despite being restricted to annual mean temperature between 4℃ and 22℃,as well as annual precipitation higher than 300 mm/year,the range of bioclimatic conditions suitable for gorse was very large.Based on a native versus introduced SDM comparison,we highlighted a niche expansion in North-West America,South America and to a lesser degree in Australia,while a niche displacement was assessed in North Europe.These niche changes induced an increase in potential occupied areas by gorse by 49,111,202 and 283%in Australia,North Europe,North-West America and South America,respectively.On the contrary,we found no evidence of niche change in New Zealand,which presents similar climatic condition to the native environment(Western Europe).This study highlights how niche expansion and displacement of gorse might increase invasibility at regional scale.The change in gorse niche toward new climatic conditions may result from adaptive plasticity or genetic evolution and may explain why it has such a high level of invasibility.Taking into account the possibility of a niche shift is crucial to improve invasive plants management and control.
文摘Pioneering studies were carried out on red-to-black pigmented grains for brewing beers.Together with pigmented cereals,the use of pulses was also proposed for making low-alcohol,gluten-free beers with improved contents of health-promoting compounds.So far,a new concept of beer is emerging among scientists,brewers,and consumers by expanding the assortment of conventional beer’s ingredients.Coloured(red,purple,blue,black)cereal grains and legume grains are an untapped resource of functional compounds.each denoting different and complementary beneficial effects on human health.Among others,polyphenols contribute to protect against non-communicable diseases such as hypertension,heart diseases,cancers,diabetes and obesity.In this review,we summarized the improvement in terms of phenolic compounds and antioxidant capacity of beers obtained by using pigmented cereal grains and pulses as raw ingredients versus traditional beers.We examined the influence of these alternative materials on the qualitative properties of the beers.Moreover,we reviewed the contribution of traditional and non-conventional yeasts on the flavour and quality of these new functional beers.Finally,we discussed the use of different and complementary chemical methods for monitoring the composition,organoleptic profile,safety,and authentication issues with the aim to highlight the most promising to protect and promote novel beer products.

文摘In the last years,the production of grape ale beer has become a trendy choice among brewers in Italy,resulting in a new beer type known as Italian Grape Ale(IGA),a sort of bridge beverage between beer and wine.In this study,three autochthonous Saccharomyces cerevisiae strains(CHE-3,P4 and TA4-10),previously isolated from different food types,were tested in comparison with the commercial strain US-05.Fermentations were conducted at a laboratory scale on malt extracts with 15%and 25%grape must adjuncts,and on malt wort(control).After fermentation,the CHE-3,P4 and TA4-10 strains showed significantly higher CO_(2) production than US-05.The main analytical parameters(organic acids,real and apparent attenuation,ethanol content,glycerol level and carbohydrate profile)and the volatile compounds related to the organoleptic quality of the experimental beers were strongly influenced both by the grape must addition to the fermentation medium and the used strains.The addition of grape must enhanced the CO_(2) production,especially when 25%of grape must was added to the wort.By comparing the tested strains,the highest aromatic expression was observed with 15%grape must adjunct.The present results confirm the importance of media composition and microbial biodiversity to gain more different beers especially in the craft beers sector.Moreover,the outcome data show the significance of microbial cross-over,a novel approach based on the exploitation of microorganisms traditionally used in other agro-food chains also for brewing novel beer types.

文摘The perceptions of fishers towards the Arrábida Marine Park,a marine protected area(MPA)in the west coast of Portugal,were studied through face-to-face interviews in two different moments of the MPA life cycle.Fishers'perceptions about the MPA and the impact it had on the fishing activity over time were identified just before the full implementation of the zoning and regulations of the management plan and 10 years later.This study aimed to investigate fishers'knowledge,acceptance and perceptions about the MPA changed with time,if support for the MPA was linked to the impact of the MPA on the fishing activity,and if fishers'perceptions about the impact of the MPA on the fishing activity match with local landings trends.Results show that although knowledge about the marine park significantly improved over time,fishers'acceptance did not.A decrease on fishers'support was not substantial but occurred.Issues such as the disagreement with regulations reinforced concerns raised during the implementation of the marine park,particularly in relation to the top-down decision-making,which commonly confers minor participation,recognition and legitimacy to fishers.Apparently,fisheries benefits were still not perceived by local fishers,though they are central for fishers'support.Further,the perceived negative impacts of the park seemed to be more related to social aspects and individual interests than to impacts on catches.Addressing adequate management,enforcement and participation of local fishers is still possible and are advocated here as to contribute to the expected socioecological outcomes and respective support,leading to the future successful performance of the Arrábida Marine Park.Assessing fishers’perceptions towards an MPA over time is central and should be included on periodical socioecological monitoring and inform an effective adaptive management.
