Cell-free DNA as a potential diagnostic biomarker in academic stress: A case-control study in young adults

Background: Stress is a pervasive issue in modern life, affecting both physical and mental health. Identifying biomarkers like cell-free DNA (cfDNA) could provide insights into stress response and help detect individuals at risk for stress-related disorders. Objective: The aim of this study is to investigate the potential use of cfDNA as a diagnostic biomarker in individuals experiencing stress. Methodology: A case-control analysis was conducted using convenient sampling on university participants (N = 285 cases, N = 500 controls) aged 18–24. The study assessed haematological and lipid profile parameters using the Sysmex XP-300TM automated analyzer and an automated biochemistry analyzer, and cfDNA was extracted using a standardized in house developed Phenol-Chloroform protocol and estimated using Agarose Gel Electrophoresis and Nanodrop. Statistical analysis was performed using SPSS ver. 21.0. Results: The results indicated a significant difference between stressed individuals and healthy controls in demographic, haematological and biochemical parameters. Specifically, stressed cases had significantly higher levels of cholesterol, LDL cholesterol, triglycerides, glucose, VLDL cholesterol, and lower levels of HDL compared to healthy controls. Stressed cases also showed significantly elevated levels of circulating cfDNA relative to healthy controls. Conclusion: These findings suggest that cfDNA may have potential as a diagnostic biomarker for stress

Managing Hepatic Encephalopathy - Combination of Lactulose and Rifaximin Versus Lactulose Monotherapy: A meta-analysis

Background: Hepatic Encephalopathy (HE), a neuropsychiatric complication of hepatic failure, is currently managed with lactulose as first-line treatment followed by other adjuncts if needed. In this meta-analysis, we determined the effect of lactulose and rifaximin combination in terms of efficacy and mortality reduction compared to lactulose alone. Materials and Methods: We searched databases (PubMed, BioMed Central, and Cochrane-Central) until July, 2022 for original studies inspecting the effects of Rifaximin and Lactulose (combination therapy) vs. lactulose as a monotherapy in the treatment of HE on outcomes of clinical efficacy, hospital stay length, HE recurrence, drugs’ side effects and mortality. Data was analyzed via Review Manager (version5.4.1) and OpenMetaAnalyst. Relative risks (RR) and weighted mean differences (WMD) with 95% confidence intervals were calculated. Results: Fifteen studies with 4327 patients were included. Pooled analysis showed combination therapy to be associated with a significantly lower mortality rate in patients having HE when compared to lactulose alone (RR 0.71 95% CI 0.58-0.88, P=0.002, I2= 68%), and clinical efficacy was also improved in the combination group (RR 1.33, 95%CI 1.19-1.48, P <0.00001, I2= 52%). HE recurrence rate, adverse events, and length of hospital stay did not significantly differ among the two groups (RR= 0.61, 95 % CI= 0.35 to 1.05, P= 0.08, I2= 84%), (RR= 0.92, 95% CI= 0.51 to 1.69, P= 0.80, I2 = 0) and (WMD −1.52, 95% CI −3.22 to 0.18, P=0.08, I2 = 83%) respectively. Conclusion: Combination therapy shows survival benefit and superior clinical efficacy over lactulose monotherapy in managing hepatic encephalopathy

Green synthesis, characterization and photocatalytic applications of silver nanoparticles using Diospyros lotus

Currently, the green route for synthesis of silver nanoparticles (Ag NPs) using plants leaf extract is an emerging research area in nanotechnology. The present study was explored for synthesis, characterization and catalytic application of Ag NPs using Diospyros lotus fresh leaf extracts. Factors affecting the synthesis were optimized and optimum conditions were pH of 8.6, silver nitrate (AgNO3) concentration of 1.5 mM and 10 mL leaf extract. Formation of Ag NPs was observed by change in color of reaction mixture from pale yellow to reddish brown. The synthesized Ag NPs were characterized using UV-Vis spectrophotometer, EDX, XRD and SEM analyses. UV-Vis spectrophotometer showed maximum absorbance peak in the range of 407 nm at different time intervals indicating formation of Ag NPs. SEM and XRD analysis confirmed face centered cubic structure and crystalline nature of biologically synthesized Ag NPs with average particle size of 27 nm. The purity of synthesized Ag NPs was revealed by EDX. Finally, photo catalytic activity (PCA) of Ag NPs was studied and 72.91% decolorization of industrial waste water was obtained at 54 h. Some important parameters like pH, turbidity, conductance; TSS, TDS, sulphide, sulphates, etc. were also monitored before and after treatment with Ag NPs
