    Mono azo reactive dyes are mostly used in textiles industries. The current study was developed to synthesize and apply mono azo reactive dyes. The primary goal of this research article is to highlight synthesized dyes with outstanding fixing properties for the dyeing and printing sectors to invent in future. Diazotized o-anisidine was coupled with several 4-amino-4ʼ-hydroxy benzilidene acetophenone cyanurated coupling component including H-acid, Gamma acid, J-acid, N-methyl J-acid, N-phenyl J-acid, K- acid and peri acid, to create a variety of monoazo reactive dyes. IR and elemental analyses were used to describe them. Moreover, the dyeing capabilities of each of these dyes on silk, wool, and cotton have been evaluated. The wet fastness properties also evaluated. Synthesized mono azo reactive dyes have excellent fixation values as well as fastness properties.Os corantes reativos monoazo são usados principalmente nas indústrias têxteis.

    From last 25 years that many researchers have developed the novel reactive dyes with modification in structure of reactive dyes. In the present review paper concentrated development of reactive dyes. The review paper is focused on the highlight such dyes have having excellent dyeing properties and wet-fastness properties. This review paper express the monstrous impression of reactive dyes on the textiles coloration industry. Particularized details are given regarding evolution in the chemistry of reactive structure systems. It is additionally mentioned pointed out that advance research is mandatory to enhance dye fixation and wet-fastness properties. Reactive dyes have been used for the past hundred years for dyeing of cellulosic fabrics. A reactive dye has a chromophore, which is a group or an atom that is responsible for the dye’s colour. It has a component which reacts with the fabric or substrate. They have excellent fastness features due to the presence of covalent bonds that takes place during dyeing. The dyeing industry is dominated by the parties who can create dyes having excellent dyeing efficiency, stable, can be resistant to chemical actions and be affordable.

    1721-1737A series of N-(1,3-benzothiazole-2-yl)-2(pyridine-3-ylformohydrazido acetamide derivatives have been synthesized by facile and efficient conventional method. The structures of the compounds have been elucidated with the aid of elemental analysis, IR, ESI-MS, and 1H and 13C NMR spectral data. Molecular docking revealed that synthesized derivatives and target proteins are actively involved in the binding pattern and had a significant correlation with biological activity. Molecular dynamics studies have also been performed and ADME parameters for the synthesized compounds determined. Biological evaluation of all synthesized compounds have been carried out in vitro for their antibacterial, antituberculosis and antifungal efficacy against various bacterial and fungal strains and H37Rv. The different studies indicate that newly synthesized compounds possess moderate to good biological activities

    Quantifying the Impact of Immune History and Variant on SARS-CoV-2 Viral Kinetics and Infection Rebound: A Retrospective Cohort Study

    Get PDF
    BACKGROUND: The combined impact of immunity and SARS-CoV-2 variants on viral kinetics during infections has been unclear. METHODS: We characterized 1,280 infections from the National Basketball Association occupational health cohort identified between June 2020 and January 2022 using serial RT-qPCR testing. Logistic regression and semi-mechanistic viral RNA kinetics models were used to quantify the effect of age, variant, symptom status, infection history, vaccination status and antibody titer to the founder SARS-CoV-2 strain on the duration of potential infectiousness and overall viral kinetics. The frequency of viral rebounds was quantified under multiple cycle threshold (Ct) value-based definitions. RESULTS: Among individuals detected partway through their infection, 51.0% (95% credible interval [CrI]: 48.3-53.6%) remained potentially infectious (Ct CONCLUSIONS: SARS-CoV-2 viral kinetics are partly determined by immunity and variant but dominated by individual-level variation. Since booster vaccination protects against infection, longer clearance times for BA.1-infected, boosted individuals may reflect a less effective immune response, more common in older individuals, that increases infection risk and reduces viral RNA clearance rate. The shifting landscape of viral kinetics underscores the need for continued monitoring to optimize isolation policies and to contextualize the health impacts of therapeutics and vaccines.

    Helicobacter species are associated with possible increase in risk of biliary lithiasis and benign biliary diseases

    <p>Abstract</p> <p>Background</p> <p>Hepato-biliary tract lithiasis is common and present either as pain or as asymptomatic on abdominal ultrasonography for other causes. Although the DNA of <it>Helicobacter </it>species are identified in the gallbladder bile, tissue or stones analyzed from these cases, still a causal relationship could not be established due to different results from different geographical parts.</p> <p>Methods</p> <p>A detailed search of pubmed and pubmedcentral was carried out with key words <it>Helicobacter </it>and gallbladder, gallstones, hepaticolithiasis, cholelithiasis and choledocholithiasis, benign biliary diseases, liver diseases. The data was entered in a data base and meta analysis was carried out. The analysis was carried out using odds ratio and a fixed effect model, 95% confidence intervals for odds ratio was calculated. Chi square test for heterogeneity was employed. The overall effect was calculated using Z test.</p> <p>Results</p> <p>A total of 12 articles were identified. One study used IgG for diagnosis while others used the PCR for Ure A gene, 16 S RNA or Cag A genes. A couple of studies used culture or histopathology besides the PCR. The cumulative results show a higher association of <it>Helicobacter </it>with chronic liver diseases (30.48%), and stone diseases (42.96%)(OR 1.77 95% CI 1.2–2.58; Z = 2.94, p = 0.003), the effect of each could not be identified as it was difficult to isolate the effect of helicobacter due to mixing of cases in each study.</p> <p>Conclusion</p> <p>The results of present meta analysis shows that there is a slight higher risk of cholelithiasis and benign liver disease (OR 1.77), however due to inherent inability to isolate the effect of stone disease from that of other benign lesions it is not possible to say for sure that <it>Helicobacter </it>has a casual relationship with benign biliary disease or stone disease or both.</p

    Activating the knowledge-to-action cycle for geriatric care in India

    Get PDF
    Despite a rapidly aging population, geriatrics - the branch of medicine that focuses on healthcare of the elderly - is relatively new in India, with many practicing physicians having little knowledge of the clinical and functional implications of aging. Negative attitudes and limited awareness, knowledge or acceptance of geriatrics as a legitimate discipline contribute to inaccessible and poor quality care for India's old. The aim of this paper is to argue that knowledge translation is a potentially effective tool for engaging Indian healthcare providers in the delivery of high quality geriatric care. The paper describes India's context, including demographics, challenges and current policies, summarizes evidence on provider behaviour change, and integrates the two in order to propose an action plan for promoting improvements in geriatric care
