The availability of directly acting antivirals (DAA) has revolutionised the management of hepatitis C in low- and middle-income countries such as India. We aimed to determine the spectrum of hepatitis C-related liver disease and the response to treatment using generic DAAs, using retrospective data collected from a cohort of adult patients. Patients with hepatocellular carcinoma, co-infection with hepatitis B, HIV and those with incomplete data were excluded. A sustained virological response was documented in 101/106 (95.3%) cases; we therefore conclude that DAAs are highly effective in the management of hepatitis C infection across a wide spectrum of clinical presentations.

The small GTPase R-RAS2 regulates homeostatic proliferation and survival of T and B lymphocytes and, when present in high amounts, drives the development of B cell chronic lymphocytic leukemia. In normal and leukemic lymphocytes, R-RAS2 constitutively binds to antigen receptors through their immunoreceptor tyrosine-based activation motifs (ITAMs) and promotes tonic activation of the phosphatidylinositol 3-kinase (PI3K) signaling pathway. Here, we examined the molecular mechanisms underlying this direct interaction and its consequences for R-RAS2 activity.

Background/purpose: Oral submucous fibrosis (OSF) is a premalignant condition of the oral cavity, and its pathogenesis remains largely unknown. A multitude of non-coding RNAs are aberrantly expressed in OSF, and their implication for the development of OSF is a matter meriting investigation.
Materials And Methods: The functional role of long non-coding RNA NCK1-AS1 in myofibroblast activation of fibrotic buccal mucosal fibroblasts (fBMFs) derived from OSF tissues was assessed.

Purpose: People who are transgender or gender diverse (PTGD) often experience difficulties navigating the health care system due to a variety of factors such as lack of knowledgeable and/or culturally competent clinicians, discrimination, and structural and/or socioeconomic barriers. We sought to determine whether a peer health navigator service in the Canadian province of Saskatchewan helped connect transgender and gender-diverse clients and health care practitioners (HCPs) to resources, and how this service changed their health care experiences.
Methods: Semistructured interviews were conducted with 9 clients and 9 HCPs.

Continuous microenvironment modulation is an ongoing challenge in wound dressing, which includes excessive exudate absorption, oxygen delivery, bacterial inhibition and angiogenesis. Herein, we developed an construction strategy to fabricate a self-retaining double-layered wound dressing, where the top layer precursor was composed of Ca-containing polyvinyl butyral (PVB) solution dispersed with hydroxypropyl methylcellulose (HPMC) particles, and the bottom one consisted of sodium alginate (Alg) solution blended with Ag-doped mesoporous bioactive glass powders (Ag-MBG). When in use, both precursors were simultaneously squeezed out from the twin nozzles connected to the individual chambers of a twin-chambered syringe, whereby Ca in the top layer rapidly migrated downwards to crosslink Alg in the bottom layer, leading to the formation of an Alg/Ag-MBG (AA) functional hydrogel for filling an irregular wound.
