A coherent probe field is assumed to connect the ground level with the intermediate level whereas a coherent control beam is supposed to act between the intermediate energy level and the uppermost level. Optical Bloch equations（OBE） for a three-level Ξ type system and a four-level Ξ type system are derived by using density matrix formalism. These equations are solved by an analytic method to determine the probe response, which not only depends on the wavelength difference between the control（pump） field and the probe field but shows substantially different features depending on whether the wavelength of the control field is greater than that of the probe field or the reverse. The effect of temperature on probe response is also shown. Enhancement in probe absorption and additional features are noticed under a strong probe limit at room temperature. The four-level Ξ type system has two ground levels and this leads to substantial modification in the simulated probe absorption as compared to the three-level system.展开更多

Four oil reservoirs in the Cretaceous including the Zubair, Buwaib, Shuaiba and Khatiyah Formations of Southern fields have been analyzed. Here is a look at that to determine main factors on decreasing resistivity in pay zone. In some intervals resistivity responses reach less than 6 to 1 ohm·m. Significant hydrocarbon accumulations are “hidden” in low resistivity Pay zone, (LRPZ). LRPZ reservoirs have been found in some formations in Persian Gulf. Causes of LRPZ reservoirs on the basis of experimental analysis include clay-coated grains, carbonate with interstitial dispersed clay. On the other side Smectite and Kaolinite of main clays types have high CEC and greater impact on lowering resistivity. Micritization and Pyritization of digenetic process have noticeable impact on LRPZ. It is mentioned that Lønøy method applied to address pore throat sizes which contain Inter crystalline porosity, Chalky Limestone, Mudstone micro porosity. Pore systems are classified at class 2 and 3 Lucia and pore size varies from 0.5 to 4 micron. NMR Core and Log results show different pore size distribution. NMR core and MRIL results explain that decreasing of resistivity in pay zone is related to texture and grain size variation not being existence of moved water. Irreducible water estimate for this reservoir was between 30% and 50%. T2 cut off estimates, for defining irreducible water saturation, 115 ms.展开更多

Methods: Ninety patients with type 2 diabetes admitted to the Department of Endocrinology of the hospital from January 2024 to June 2024 were selected. The control group (n = 45) received routine nursing care, while the observation group (n = 45) received whole-course nursing. Indicators such as glucose metabolism and compliance behavior were measured before and after care, and the health and quality of life of patients in both groups were evaluated. Results: A comparison of blood glucose levels and compliance behavior showed that the observation group had lower blood glucose levels than the control group (P < 0.05). Additionally, the compliance behavior score of the observation group was higher than that of the control group (P < 0.05). Conclusion: The holistic nursing model demonstrates significant nursing effects for patients with type 2 diabetes. This approach not only assists in blood sugar control, prevents disease progression, and reduces complications, but also enhances patients’ knowledge of health management, aiding in their recovery.展开更多

文摘We classify a generalized coupled singular Emden-Fowler type system ＋a（t）vn=0,v＋b（t）um=0 with respect to the standard first-order Lagrangian according to the Noether point symmetries which it admits.First integrals of the various cases which admit Noether point symmetries are then obtained.This system was discussed in the literature from the view-point of existence and uniqueness of positive solutions.
文摘Effect of residual Doppler averaging on the probe absorption in an alkali vapor medium in the presence of a coherent pump beam is studied analytically for the Ξ type system. A coherent probe field is assumed to connect the ground level with the intermediate level whereas a coherent control beam is supposed to act between the intermediate energy level and the uppermost level. Optical Bloch equations（OBE） for a three-level Ξ type system and a four-level Ξ type system are derived by using density matrix formalism. These equations are solved by an analytic method to determine the probe response, which not only depends on the wavelength difference between the control（pump） field and the probe field but shows substantially different features depending on whether the wavelength of the control field is greater than that of the probe field or the reverse. The effect of temperature on probe response is also shown. Enhancement in probe absorption and additional features are noticed under a strong probe limit at room temperature. The four-level Ξ type system has two ground levels and this leads to substantial modification in the simulated probe absorption as compared to the three-level system.

文摘DNA molecules are green materials with great potential for high-density and long-term data storage.However,the current data-writing process of DNA data storage via DNA synthesis suffers from high costs and the production of hazards,limiting its practical applications.Here,we developed a DNA movable-type storage system that can utilize DNA fragments pre-produced by cell factories for data writing.In this system,these pre-generated DNA fragments,referred to herein as“DNA movable types,”are used as basic writing units in a repetitive way.The process of data writing is achieved by the rapid assembly of these DNA movable types,thereby avoiding the costly and environmentally hazardous process of de novo DNA synthesis.With this system,we successfully encoded 24 bytes of digital information in DNA and read it back accurately by means of high-throughput sequencing and decoding,thereby demonstrating the feasibility of this system.Through its repetitive usage and biological assembly of DNA movable-type fragments,this system exhibits excellent potential for writing cost reduction,opening up a novel route toward an economical and sustainable digital data-storage technology.
文摘The main focus of study is to characterize lower and upper cretaceous carbonate deposits with Low Resistivity Pay, in Persian Gulf. Four oil reservoirs in the Cretaceous including the Zubair, Buwaib, Shuaiba and Khatiyah Formations of Southern fields have been analyzed. Here is a look at that to determine main factors on decreasing resistivity in pay zone. In some intervals resistivity responses reach less than 6 to 1 ohm·m. Significant hydrocarbon accumulations are “hidden” in low resistivity Pay zone, (LRPZ). LRPZ reservoirs have been found in some formations in Persian Gulf. Causes of LRPZ reservoirs on the basis of experimental analysis include clay-coated grains, carbonate with interstitial dispersed clay. On the other side Smectite and Kaolinite of main clays types have high CEC and greater impact on lowering resistivity. Micritization and Pyritization of digenetic process have noticeable impact on LRPZ. It is mentioned that Lønøy method applied to address pore throat sizes which contain Inter crystalline porosity, Chalky Limestone, Mudstone micro porosity. Pore systems are classified at class 2 and 3 Lucia and pore size varies from 0.5 to 4 micron. NMR Core and Log results show different pore size distribution. NMR core and MRIL results explain that decreasing of resistivity in pay zone is related to texture and grain size variation not being existence of moved water. Irreducible water estimate for this reservoir was between 30% and 50%. T2 cut off estimates, for defining irreducible water saturation, 115 ms.

文摘Toxin–antitoxin(TA)systems,which are prevalent in bacteria and archaea,play diverse roles in bacterial physiology and have been proposed to be significant in stress adaptation.Despite the extensive characterization of numerous TA systems in various bacteria,the investigation of these systems within Streptococcus suis is still limited.Here,we systematically analyzed the type Ⅱ TA systems of 95 S.suis genomes available in the GenBank database using TAfinder.A total of 612 putative type Ⅱ TA systems were retrieved and classified into 10 categories by phylogenetic analysis.Notably,an elevated occurrence of these TA systems was observed among the important prevalent serotypes 2,4,5,9,14,Chz,NCL1,and NCL3 strains.The following study identified the activities of TA systems using 2 strategies and confirmed the regulatory effect of HigBA on the type Ⅶ secretion system in S.suis by measuringβ-galactosidase activity and transcriptional changes.Moreover,we unveiled a hitherto uncharacterized,highly prevalent novel TA system,with the composition of antitoxin–toxin–antitoxin(SS-ATA),which regulates the downstream two-component signaling system.Altogether,this study systematically analyzed the type Ⅱ TA systems within S.suis,highlighting the widespread distribution of Hig BA and SS-ATA as important regulatory elements in S.suis.
文摘BACKGROUND The incidence of type 2 diabetes mellitus(T2DM)in children and adolescents is increasing,yet there is limited information on the available pharmacological interventions to combat T2DM and prevent associated comorbidities.AIM To assess the effectiveness of current pharmacological treatments in managing T2DM in children and adolescents.The protocol of the study was registered in PROSPERO(CRD42022382165).METHODS Searches were performed in PubMed,EMBASE,Scopus,and ClinicalTrials.gov for publications between 1990 to September 2024 without language restrictions.Randomized control trials(RCTs)of pharmacotherapy in children and adolescents with T2DM(aged<19 years)were included.The primary outcome was a change in glycated hemoglobin(HbA1c)from baseline to follow-up.Secondary outcomes were changes in body weight,body mass index(BMI),total cholesterol,triglycerides,high density lipoprotein,and low-density lipoprotein from baseline,and incidence of adverse events during study periods.Screening,full-text review,data extraction,and assessments of risk of bias were done by two reviewers.Conflicts on each step were resolved by a third reviewer.Data analysis was performed using Review Manager Version 6.5(RevMan 6.5)and‘R’software via RStudio,‘meta’and‘netmeta’.RESULTS A total of 12 studies having low to moderate risk of bias with 1658 participants,and follow-up duration 12-52 weeks were included.In our network meta-analysis,compared to control(s),the reduction of HbA1c was sig-nificantly larger for dulaglutide[mean difference(MD),95%confidence interval:-1.20,-2.12 to-0.28],followed by dapagliflozin(-0.94,-1.44 to-0.44),liraglutide(-0.91,-1.37 to-0.45),empagliflozin(-0.87,-1.40 to-0.34),exenatide(-0.59,-1.07 to-0.11)and linagliptin(-0.45,-0.87 to-0.02)while other drugs had little or no effect.While liraglutide was associated with a change in body weight[MD-2.41(-4.68,-0.14)kg],no other drug treatment was associated with significant changes in body weight,BMI,and lipids.Apart from level 1 hypoglycemia with liraglutide[risk difference(RD):0.20,0.04-0.37]and minor adverse events with dulaglutide(RD:0.24,0.08-0.40),no other treatment was associated with excess risk of hypoglycemia or minor or major adverse events.CONCLUSION Pharmacotherapy of T2DM with dulaglutide,dapagliflozin,liraglutide,empagliflozin,exenatide,and linagliptin in children is associated with modest reduction of HbA1c.Larger RCTs with longer follow-up durations are needed to guide better therapeutic decision making.

文摘BACKGROUND Pyroptosis and ubiquitination have been identified as key processes influencing the pathogenesis of diabetes mellitus(DM).AIM To investigate the genes associated with the ubiquitin-proteasome system(UPS)and pyroptosis in type 2 DM(T2DM),and elucidate their mechanisms of action in T2DM.METHODS The datasets GSE76894,GSE41762,and GSE86469 were utilized in this study.UPS-related genes(UPSGs)and pyroptosis-related genes(PRGs)were obtained from existing literature.Differential expression analysis was performed to identify differentially expressed genes(DEGs).DEGs were intersected with UPSGs and PRGs to identify differentially expressed UPSGs and PRGs.Ubiquitin-pyroptosisrelated biomarkers were determined using Spearman’s correlation,t-tests,and receiver operating characteristic curve analysis.Pathway enrichment of biomarkers was assessed using Gene Set Enrichment Analysis(GSEA).Single sample GSEA(ssGSEA)and Spearman’s correlation were used to analyze the relationship between biomarkers and immune cells.A competitive endogenous RNA network was constructed.Subsequently,drugs related to the biomarkers were identified and a gene-drug network was established.In dataset GSE86469,single-cell sequencing was utilized to determine cell types.Finally,the expression levels of biomarkers were validated through quantitative PCR(qPCR)and western blot analysis.RESULTS A total of 581 DEGs were identified in GSE76894.Four genes[ATP binding cassette subfamily C member 8(ABCC8),retinol binding protein 4(RBP4),Ras protein-specific guanine nucleotide-releasing factor 1(RASGRF1),and solute carrier family 34 member 2(SLC34A2)]were identified as ubiquitin-pyroptosis-related biomarkers in T2DM,based on consistent expression trends and significant differences in GSE76894 and GSE41762.These biomarkers were enriched in oxidative phosphorylation and mitogen-activated protein kinase signaling pathways,which are relevant to DM.ssGSEA revealed significant differences in the enrichment scores of nine immune cell types between groups.A total of 17 microRNAs(miRNAs)and 36 long non-coding RNAs(lncRNAs)were identified,forming numerous miRNA-lncRNA interactions.Additionally,22 drugs related to the biomarkers,such as gliclazide and tretinoin,were identified.In GSE86469,eight cell types,including alpha and beta cells,were characterized.qPCR and western blot analysis confirmed that the expression trends of RASGRF1 and SLC34A2 were consistent with the findings in GSE76894.CONCLUSION This study identified four ubiquitin-pyroptosis-related biomarkers(ABCC8,RBP4,RASGRF1,and SLC34A2)in T2DM through bioinformatics analysis,providing novel insights into the diagnosis and treatment of T2DM.
文摘BACKGROUND Diabetes distress(DD),an emotional problem arising from the challenges of living with diabetes and the relentless burden of daily self-management,is common among patients with type 2 diabetes(T2D).South Asia has a high T2D burden,and many studies have reported varying prevalence rates of DD in this area.AIM To estimate the pooled prevalence of DD among patients with T2D in South Asia,as it is crucial for developing effective therapeutic strategies.METHODS This systematic review and meta-analysis included cross-sectional studies conducted in South Asian countries involving adults with T2D and reported the prevalence of DD.The studies were identified by searching multiple electronic databases and registries from the inception of each database to January 30,2025,using prespecified search terms.Four authors screened and extracted data independently.Meta-analyses were conducted using RStudio software with a random-effects model.The primary outcome was the pooled prevalence of DD.RESULTS Thirty-seven cross-sectional studies(28 from India,five from Bangladesh,and two each from Pakistan and Sri Lanka)with mostly high methodological quality involving 11500 subjects were included.The pooled prevalence of DD was 44%(95%confidence interval:35-53,I2=97.4%).The prevalence of DD was highest in Pakistan(85%),followed by India and Bangladesh(42%each),and Sri Lanka(25%).Emotional burden was the most prevalent form of DD(60%),followed by treatment regimen-related distress(51%),interpersonal distress(31%),and physician-related distress(17%).Meta-regression analysis revealed no significant associations between the prevalence of DD and publication year,sample size,proportion of females,age,duration of diabetes,insulin usage,glycated hemoglobin levels,or diabetic complications.CONCLUSION South Asians with T2D seem to experience a relatively high burden of DD,and the emotional burden is the most common form of DD in this area.Larger studies utilizing unique tools and involving a broader participant base from the region would provide better epidemiological data for effectively planning high-quality diabetes care in South Asian countries.
文摘BACKGROUND Type 2 diabetes(T2D)is a major health concern globally and its prevalence is expected to continue to escalate.Lifestyle intervention is an integral part of T2D management.Meal replacements are often used as part of lifestyle intervention programs in T2D and weight management programs.There are various trials being carried out to date;however,a thorough review regarding the usage of meal replacement on its types,dosage and associated outcomes and adverse events is still lacking.AIM To provide a comprehensive overview on existing studies regarding meal replacement usage among patients with T2D,and map out glycemic and weightrelated outcomes along with adverse effects incidences.METHODS This scoping review is conducted based on Arksey and O’Malley’s seminal framework for scoping reviews.A systematic search has been done for studies published between January 2020 and January 2024 across six online databases(Cochrane Library,PubMed,Science Direct,Scopus,Web of Science and Ebscohost Discovery)using specific keywords.Two researchers independently assessed the eligibility of the studies and extracted the data.The selected articles and extracted data were reviewed by all researchers.RESULTS The initial search resulted in an initial count of 53922 articles from which 133 articles were included in this review after eligibility screening.Included studies were categorized based on meal replacement type into low calorie/energy,low glycemic index,protein-rich,low-fat,diabetes-specific formulas,and combined lifestyle intervention programs.Fifty-nine studies reported improvements on hemoglobin A1c,and 70 studies reported positive changes in weight or BMI after the meal replacement intervention.The combination of meal replacements with education,counseling or structured lifestyle interventions has proved to be effective.Only 13 studies reported occurrence of adverse events related to the intervention.Most of the reported incidents were of mild occurrences with constipation being the most reported adverse event.CONCLUSION The results suggest that meal replacements,especially when combined with lifestyle intervention programs and counseling,are an effective and safe strategy in glycemic and weight management among patients with T2D.

文摘Alzheimer’s dementia(AD)and type 2 diabetes(T2D)are interrelated global public health problems,and the current epidemics of both AD and T2D are insulin resistance diseases.Thus,AD and T2D may share common risk factors such as an unhealthy diet,lifestyle,and obesity.Meat products is an important part of the diet of consumers worldwide.This systematic review and meta-analysis aims to assess and estimate the effect of meat products consumption on AD and T2D in humans.Web of Science,MEDLINE,PubMed,Cochrane Library,and Embase were searched from January 2012 to April 2024.29 articles reported 32 cohort studies with 1785769 subjects,with 3546 AD cases and 91092 T2D cases that met the inclusion criteria and were included in our analysis.Consumption of various meat products increased the risk of T2D(hazard ratios(HR)=1.19,95%confidence intervals(CI):1.13−1.26,P=0.000;I2=88.5%),consumption of smoked,grilled/roasted and fried meat products was more likely to induce T2D(HR=1.24,95%CI:1.18−1.30,P=0.000;I2=76.1%),but was borderline significant for the risk of AD(HR=1.11,95%CI:0.98−1.25,P=0.094;I2=58.8%),with consumption of mainly livestock and poultry products increasing the risk(HR=1.21,95%CI:1.03−1.42,P=0.017;I2=66.8%).The association between meat products consumption and AD risk was influenced by meat type and sample size,while the risk of T2D was influenced by meat type,follow-up and sex.A daily intake of 27,123 and 170 g of livestock products increased the risk of T2D by 10%,51%and 70%respectively,whereas the risk of T2D was reduced when the intake of various meat products was less than 23 g/day.
文摘Objective Epidemiological studies have shown that vitamin D status affects glycemic control in individuals with type 2 diabetes mellitus(T2DM).However,findings from intervention studies remain inconsistent.Therefore,a network meta-analysis was conducted to evaluate the comparative efficacy of various vitamin D supplementation strategies on glucose indicators in adults with T2DM.Methods Eligible studies published before September 12,2024,were retrieved from PubMed,EMBASE,Cochrane Library,and Web of Science.A network meta-analysis of multiple dosage strategies—low(<1,000 IU/day,LDS),medium(1,000–2,000 IU/day,MDS),high(2,000–4,000 IU/day,HDS),and extremely high(≥4,000 IU/day,EHDS)—was performed.Results The network meta-analysis of 40 RCTs indicated that,compared with placebo,vitamin D_(3)supplementation increased 25-hydroxyvitamin D[25-(OH)-D]levels,with pooled mean difference(MD)showing a stepwise increase from LDS to EHDS.Ranking probabilities showed a corresponding rise in 25-(OH)-D levels from LDS(46.7%)to EHDS(91.2%).EHDS reduced fasting blood glucose(FBG)relative to no treatment.LDS significantly decreased hemoglobin A1c(HbA1c),and vitamin D_(2) significantly affected FBG levels.MDS led to a significant change in fasting insulin(FIN)compared to both placebo(MD:-4.76;95%CI-8.91 to-0.61)and no treatment(MD:-7.30;95%CI-14.44 to-0.17).Conclusion The findings suggest that vitamin D supplementation may be a viable approach for improving glycemic control in adults with T2DM,with lower doses potentially offering benefit.The analysis also showed a dose-dependent increase in 25-(OH)-D levels.
文摘Objective: To explore the effect of a whole-course nursing objective management system on disease control and quality of life in patients with type 2 diabetes, and to propose strategies for constructing such a system for these patients. Methods: Ninety patients with type 2 diabetes admitted to the Department of Endocrinology of the hospital from January 2024 to June 2024 were selected. The control group (n = 45) received routine nursing care, while the observation group (n = 45) received whole-course nursing. Indicators such as glucose metabolism and compliance behavior were measured before and after care, and the health and quality of life of patients in both groups were evaluated. Results: A comparison of blood glucose levels and compliance behavior showed that the observation group had lower blood glucose levels than the control group (P < 0.05). Additionally, the compliance behavior score of the observation group was higher than that of the control group (P < 0.05). Conclusion: The holistic nursing model demonstrates significant nursing effects for patients with type 2 diabetes. This approach not only assists in blood sugar control, prevents disease progression, and reduces complications, but also enhances patients’ knowledge of health management, aiding in their recovery.
