    Cleome viscosa L. (Capparidaceae), commonly known as “wild mustard”, is an annual, sticky herb found as common weed all over the plains of India and throughout the tropics of the world. In traditional systems of medicine the plant is reported to possess beneficial effects as an anthelmintic, antiseptic, carminative, antiscorbutic, febrifuge, and cardiac stimulant.     The aim of the present study was to evaluate to antioxidant activity of 70% methnolic extract of leaf and stem part of Cleome viscosa (CV) by using different in vitro model such as β carotene bleaching assay, reducing power and free radical scavenging activity (DPPH and hydroxyl radical scavenging activity). Total phenolic content were estimated by the Folin–Ciocalteu colorimetric method using gallic acid as standard and expressed as mg/g gallic acid equivalent (GAE) and total flavonoid content was estimated by aluminium chloride colourimetric method. The total phenolic, flavonoid content and antioxidant activity of Cleome viscosa leaves were found to be 66.38±0.82mg/g, 0.54±0.04mg/g and 77.30% respectively. Cleome viscosa leaves showed high free radical scavenging activity as evidenced by the low IC50 values in both DPPH (1,1-diphenyl-2-picryl hydrazyl) (373.18 μg/ml) and hydroxyl radical (573.55 μg/ml) methods. Cleome viscosa leaves possess high phenolic, flavonoid content and potential antioxidant activity, reducing power and free radical scavenging activity in comparison to stem

    A total of 1,020 poultry birds belonging to twelve different localities of Jaunpur district were surveyed during May 2006 to April 2007 to record the prevalence rate of Eomenacanthus stramineus. Prevalence of E. stramineus was noted more or less similar in both the sexes (Male – 38% and Female – 39%). Maximum birds bore very low infestation (32%) while only 7% birds exhibited very heavily infestation. Host sex, feather colour and locality had negligible effect on prevalence rate. However, prevalence rate remained slightly higher on birds with poor plumage/health. Significant positive correlation existed between mean monthly prevalence rate and mean monthly temperature as well as photoperiod. Mean monthly incidence rate were recorded higher during summer (May and June) as compared to winter months

    ObjectivesThe purpose of this study was to determine whether the rate of hospital admission for acute myocardial infarction (AMI) varies seasonally in a large, prospective U.S. registry.BackgroundIdentification of specific patterns in the timing of the onset of AMI is of importance because it implies that there are triggers external to the atherosclerotic plaque. Using death certificate data, most investigators have noted a seasonal pattern to the death rate from AMI. However, it is unclear whether this observation is due to variation in the prevalence of AMI or to other factors that may alter the likelihood of a fatal outcome.MethodsWe examined the seasonal mean number of cases of AMI (adjusted for the length of days in each season) that were submitted to the National Registry of Myocardial Infarction (NRMI) by 138 high volume core hospitals over a 3-year period (December 21,1990 through December 20,1993) during which the number of hospitals participating in the Registry was stable. Data were analyzed using general linear modeling and analysis of variance.ResultsHigh volume core hospitals reported 83,541 cases of AMI to the Registry during the study period. Approximately 10% more such cases were entered into the Registry in winter or spring than in summer (p < 0.05). The same trends were seen in both northern and southern states, men and women, patients <70 versus ≥70 years of age and those with Q wave versus non-Q wave AMI.ConclusionsWe conclude that there is a seasonal pattern to the reporting rate of cases of AMI in the NRMI. This observation further supports the hypothesis that acute cardiovascular events may be triggered by events that are external to the atherosclerotic plaque

    Objective: The aim of the present study was to evaluate the efficacy of naringenin against antituberculosis drugs (ATDs) induced alteration in hematological parameters in rats.Methods: Rats were administered with ATDs for 8 weeks (3 days/weeks) followed by naringenin at three different doses (10, 20, and 40 mg/kg) conjointly for 8 weeks (3 days/weeks) orally. After 8 weeks, animals were euthanized; blood was collected by retro-orbital sinus method for the analysis of hematological parameters.Results: The results of this study show decreased in red blood cells, hemoglobin, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, platelets, and eosinophils along with increase in the number of lymphocytes in ATDs induced rats. Treatment with naringenin encountered ATDs induced hematological parameter alteration which was evident by significant reversal in hematological indices toward control in dose-dependent manner.Conclusion: The present study concluded that ATDs exposure caused adverse effects in various blood components and conjoint treatment of naringenin reduced hematological alterations toward control due to antioxidant activity

    Objectives: Alcohol abuse leads to several diseases and millions of death worldwide. High-fat diet (HFD) is major contributor of non-alcoholic liver diseases and obesity. Combined consumption of HFD and alcohol has deleterious effect on blood cells. This study was carried out to evaluate the protective effect of rutin against combined consumption of HFD and alcohol-induced hematological alterations.Methods: HFD 30% and ethanol 10% were administered for 4 weeks for induction of toxicity. Rutin (10, 20, and 40 mg/kg) and 50 mg/kg dose of silymarin were administered along with HFD and alcohol for 4 weeks.Results: Combined consumption of HFD and alcohol increased mean corpuscular volume, total leukocytes count, eosinophil and monocyte, and decreased hematocrit and platelets. Administration of rutin improved hematological variables altered by HFD and alcohol consumption.Conclusion: The present study concluded that administration of rutin may alleviate HFD and alcohol-induced hematological alterations by scavenging free radicals generation

    BackgroundEfficient detection tools for determining staphylococcal pleural infection are critical for its eradication. The objective of this meta-analysis was to assess the diagnostic utility of nucleic acid amplification tests (NAAT) in suspected empyema cases to identify staphylococcal strains and avoid unnecessary empiric methicillin-resistant Staphylococcus aureus (MRSA) therapy.MethodsFrom inception to July 24, 2021, relevant records were retrieved from PubMed, Embase, Scopus, Web of Science, and the Cochrane Library. The quality of studies was determined using the QUADAS-2 tool. The pooled sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR), diagnostic odds ratio (DOR), and hierarchical summary receiver operating characteristic (HSROC) curve for NAAT’s diagnostic performance were evaluated using an HSROC model.ResultsEight studies comprising 424 samples evaluated NAAT accuracy for Staphylococcus aureus (SA) identification, while four studies comprising 317 samples evaluated methicillin-resistant Staphylococcus aureus (MRSA) identification. The pooled NAAT summary estimates for detection of both SA (sensitivity: 0.35 (95% CI 0.19–0.55), specificity: 0.95 (95% CI 0.92–0.97), PLR: 7.92 (95% CI 4.98–12.59), NLR: 0.44 (95% CI 0.14–1.46), and DOR: 24.0 (95% CI 6.59–87.61) ) and MRSA (sensitivity: 0.45 (95% CI 0.15–0.78), specificity: 0.93 (95% CI 0.89–0.95), PLR: 10.06 (95% CI 1.49–67.69), NLR: 0.69 (95% CI 0.41–1.15), and DOR: 27.18 (95% CI 2.97–248.6) ) were comparable. The I2 statistical scores for MRSA and SA identification sensitivity were 13.7% and 74.9%, respectively, indicating mild to substantial heterogeneity. PCR was frequently used among NAA tests, and its diagnostic accuracy coincided well with the overall summary estimates. A meta-regression and subgroup analysis of country, setting, study design, patient selection, and sample condition could not explain the heterogeneity (meta-regression P = 0.66, P = 0.46, P = 0.98, P = 0.68, and P = 0.79, respectively) in diagnostic effectiveness.ConclusionsOur study suggested that the diagnostic accuracy of NAA tests is currently inadequate to substitute culture as a principal screening test. NAAT could be used in conjunction with microbiological culture due to the advantage of faster results and in situations where culture tests are not doable
