    From yarns to fibers to fabric, a finished garment goes through various challenges to meet our requirements. One of the major factors that affect a woven fabric is ‘Abrasion Resistance’. Abrasion is basically the mechanical deterioration of fabric components by rubbing them  against another surface. It ultimately results in the loss of the fabrics’ performance and its appearance. This paper shall deal with the various aspects of a woven fabric with respect to abrasion resistance, its tests and various experiments and the effect it has on the weave of the fabric

    Background: Cleaning and shaping of root canal system requires various irrigating solutions. The question is whether the presence of irrigation solution alters working length determination using apex locators. The purpose of this study was to compare the accuracy of Root ZX and i-Root apex locator for determining working length in the presence of different irrigating solution.Materials and method: Eighty extracted single rooted human teeth were used. The teeth were sectioned at Cemento Enamel Junction (CEJ) and actual canal length determined. Then, working length measurements were obtained using Root ZX and i-Root apex locator in the presence of irrigating solutions namely 0.9% saline, 3% of sodium hypochlorite (NaOCl), 2% chlorhexidine digluconate(CHX) and 17% Ethylene Diamine Tetra Acetic acid (EDTA). The measurements obtained with Root ZX and i-Root apex locator were compared with actual canal length and subjected to statistical analysis using Post Hoc Test Tukey’s Method.Results: This study revealed that both the tested Electronic apex locators (EAL) were able to measure the canal length in the presence of tested irrigating solutions. The presence of irrigating solutions of saline, NaOCl, chlorhexidine and EDTA in the root canal marginally influenced the accuracy of the Root ZX or i-Root (P < 0.36), but with no clinical significance.Conclusion: Root ZX and i-Root can be used safely to determine working length in the presence of various irrigants. The content of the root canal did not influence the accuracy while measuring working length using Electronic apex locators (EAL)Keywords: Chlorhexidine, Root ZX, i–Root Apex locator, sodium hypochlorite, salin

    Global impact of tobacco control policies on smokeless tobacco use: A systematic review protocol

    Get PDF
    Introduction Smokeless tobacco (ST) was consumed by 356 million people globally in 2017. Recent evidence shows that ST consumption is responsible for an estimated 652 494 all-cause deaths across the globe annually. The WHO Framework Convention on Tobacco Control (FCTC) was negotiated in 2003 and ratified in 2005 to implement effective tobacco control measures. While the policy measures enacted through various tobacco control laws have been effective in reducing the incidence and prevalence of smoking, the impact of ST-related policies (within WHO FCTC and beyond) on ST use is under-researched and not collated. Methods and analysis A systematic review will be conducted to collate all available ST-related policies implemented across various countries and assess their impact on ST use. The following databases will be searched: Medline, EMBASE, PsycINFO, Cumulative Index to Nursing and Allied Health Literature, Scopus, EconLit, ISI Web of Science, Cochrane Library (CENTRAL), African Index Medicus, LILACS, Scientific Electronic Library Online, Index Medicus for the Eastern Mediterranean Region, Index Medicus for South-East Asia Region, Western Pacific Region Index Medicus and WHO Library Database, as well as Google search engine and country-specific government websites. All ST-related policy documents (FCTC and non-FCTC) will be included. Results will be limited to literature published since 2005 in English and regional languages (Bengali, Hindi and Urdu). Two reviewers will independently employ two-stage screening to determine inclusion. The Effective Public Health Practice Project's 'Quality Assessment Tool for Quantitative Studies' will be used to record ratings of quality and risk of bias among studies selected for inclusion. Data will be extracted using a standardised form. Meta-analysis and narrative synthesis will be used. Ethics and dissemination Permission for ethics exemption of the review was obtained from the Centre for Chronic Disease Control's Institutional Ethics Committee, India (CCDC-IEC-06-2020; dated 16 April 2020). The results will be disseminated through publications in a peer-reviewed journal and will be presented in national and international conferences.

    Understanding the dynamics of notification and implementation of Article 5.3 across India's states and union territories

    Get PDF
    INTRODUCTION: In federal systems, state and local governments may offer opportunities for innovation in implementing the WHO Framework Convention on Tobacco Control (FCTC). This paper explores the implementation of WHO FCTC Article 5.3 within India’s federal system, examining how its guidelines have been operationalised across states and union territories. METHODS: Interviews with officials from government and civil society organisations across key states, and a document review of state government and district administration notifications adopting Article 5.3 guidelines between 2015 and 2019. RESULTS: The data reveal subnational leadership in formulating intersectoral committees, which are designed to limit interactions with the tobacco industry, and corresponding measures to reject partnership and conflicts of interest for government officials. There are notable omissions across states and union territories in adoption of key Article 5.3 guidelines; only four districts and state governments refer to regulating aspects of ‘socially responsible’ industry activities, and no notifications include measures to prevent the tobacco industry receiving preferential treatment or requiring that information provided by industry actors be transparent and accountable. Interview data indicate that dynamics of notification across states have been shaped by lesson drawing and the catalytic role of civil society. The adoption of protocols is impacting on the practices of health officials, but there are concerns about engagement by other departments and the regulatory capacity of empowered committees. CONCLUSION: The spread of state- and district-level policies illustrates opportunities federal structures can provide for accelerating tobacco control. Given significant omissions and policy tensions, there remains a need for national action to build on these innovations, including in revisions to India’s tobacco control legislation

    Impact of tobacco price and taxation on affordability and consumption of tobacco products in the Southeast Asia Region : a systematic review

    Introduction: The objective of the review was to study the impact of tobacco taxes or prices on affordability and/or consumption of tobacco products in WHO-South East Asia Region (SEAR) countries, overall, and by socioeconomic status; and change in consumption of one tobacco product for a given change in price/tax on other tobacco product. Methods: The searches were run on five databases (Medline, Embase, Cinahl, EconLit, Tobacconomics) using keywords such as ‘tobacco’, ‘tax’, ‘price’, ‘impact’ with their synonyms. Additionally, first 100 articles through google search and e-reports from targeted sources were also reviewed. Studies illustrating the impact of prices/taxes on consumption/affordability of tobacco products in SEAR, available in English language, with no limitation on time were included in the review. After two steps of screening, data from 28 studies were extracted using a structured, and pre-tested data extraction form. Results: Out of the total twenty-eight studies, twelve studies reported an inverse association between price and consumption/affordability while 11 studies reported no or positive association between price and consumption/affordability of tobacco products. Five studies had unclear interpretations. Majority of studies estimated that the less affluent group were more price responsive as compared to the more affluent group. Some studies indicated increased consumption of one product in response to price rise of other product, although, the findings were inconsistent. Conclusions: The findings of our review support the use of tobacco tax and price measures as effective tools to address the tobacco epidemic. Our findings however also emphasise the importance of increasing tobacco product taxes and prices sufficiently to outweigh the effects of income growth, in order for the measures to be effective in reducing the affordability and consumption of tobacco products

    Mouse models of diffuse large B cell lymphoma

    Get PDF
    Diffuse large B cell lymphoma (DLBCL) is a genetically highly heterogeneous disease. Yet, to date, the vast majority of patients receive standardized frontline chemo-immune-therapy consisting of an anthracycline backbone. Using these regimens, approximately 65% of patients can be cured, whereas the remaining 35% of patients will face relapsed or refractory disease, which, even in the era of CAR-T cells, is difficult to treat. To systematically tackle this high medical need, it is important to design, generate and deploy suitable in vivo model systems that capture disease biology, heterogeneity and drug response. Recently published, large comprehensive genomic characterization studies, which defined molecular sub-groups of DLBCL, provide an ideal framework for the generation of autochthonous mouse models, as well as an ideal benchmark for cell line-derived or patient-derived mouse models of DLBCL. Here we discuss the current state of the art in the field of mouse modelling of human DLBCL, with a particular focus on disease biology and genetically defined molecular vulnerabilities, as well as potential targeting strategies

    Prospective, multicentre study of screening, investigation and management of hyponatraemia after subarachnoid haemorrhage in the UK and Ireland

    Background: Hyponatraemia often occurs after subarachnoid haemorrhage (SAH). However, its clinical significance and optimal management are uncertain. We audited the screening, investigation and management of hyponatraemia after SAH. Methods: We prospectively identified consecutive patients with spontaneous SAH admitted to neurosurgical units in the United Kingdom or Ireland. We reviewed medical records daily from admission to discharge, 21 days or death and extracted all measurements of serum sodium to identify hyponatraemia (<135 mmol/L). Main outcomes were death/dependency at discharge or 21 days and admission duration >10 days. Associations of hyponatraemia with outcome were assessed using logistic regression with adjustment for predictors of outcome after SAH and admission duration. We assessed hyponatraemia-free survival using multivariable Cox regression. Results: 175/407 (43%) patients admitted to 24 neurosurgical units developed hyponatraemia. 5976 serum sodium measurements were made. Serum osmolality, urine osmolality and urine sodium were measured in 30/166 (18%) hyponatraemic patients with complete data. The most frequently target daily fluid intake was >3 L and this did not differ during hyponatraemic or non-hyponatraemic episodes. 26% (n/N=42/164) patients with hyponatraemia received sodium supplementation. 133 (35%) patients were dead or dependent within the study period and 240 (68%) patients had hospital admission for over 10 days. In the multivariable analyses, hyponatraemia was associated with less dependency (adjusted OR (aOR)=0.35 (95% CI 0.17 to 0.69)) but longer admissions (aOR=3.2 (1.8 to 5.7)). World Federation of Neurosurgical Societies grade I–III, modified Fisher 2–4 and posterior circulation aneurysms were associated with greater hazards of hyponatraemia. Conclusions: In this comprehensive multicentre prospective-adjusted analysis of patients with SAH, hyponatraemia was investigated inconsistently and, for most patients, was not associated with changes in management or clinical outcome. This work establishes a basis for the development of evidence-based SAH-specific guidance for targeted screening, investigation and management of high-risk patients to minimise the impact of hyponatraemia on admission duration and to improve consistency of patient care
