Basella alba stem extract integrated poly (vinyl alcohol)/chitosan composite films: A promising bio-material for wound healing.

Natural extract-based bio-composite material for wound healing is gaining much attention due to risk of infection and high cost of commercial wound dressing film causes serious problem on the human well-being. Herein, the study outlines the preparation of Poly (vinyl alcohol)/Chitosan/Basella alba stem extract (BAE) based bio-composite film through solvent casting technique and well characterized for wound healing application. Incorporation of BAE into Poly (vinyl alcohol)/Chitosan matrix has shown existence of secondary interactions confirmed by FT-IR analysis. Good morphology, thermal stability and significant improvement in flexibility (∼63.38 %) of the films were confirmed by SEM, TGA and Mechanical test results, respectively. Hydrophilic property (∼9.04 %), water vapor transmission rate (∼70.07 %), swelling ability (∼14.7 %) and degradation rate (∼14.04 %) were enhanced with increase in BAE content. In-vitro studies have shown good antibacterial activity against foremost infectious bacterial strains S. aureus and E. coli. Additionally, BAE integrated Poly (vinyl alcohol)/Chitosan film has amplified anti-inflammatory (∼79.38 %) property, hemocompatibility and excellent biocompatibility (94.9 %) was displayed by cytotoxicity results. Moreover, in-vitro scratch assay and cell adhesion test results illustrated prominent wound healing (96.5 %) and adhesion. Overall results of the present work proclaim that developed bio-composite film could be utilized as a biomaterial in wound care applications.

"In transition: ensuring the sexual and reproductive health and rights of transgender populations." A roundtable discussion.

This roundtable discussion is the result of a research symposium entitled In Transition: Gender [Identity], Law & Global Health where participants took up the challenge to engage with the question: What will it take to ensure the sexual and reproductive health and rights (SRHR) of transgender populations across the globe? The barriers to overcome are fierce, and include not only lack of access to health services and insurance but also stigma and discrimination, harassment, violence, and violations of rights at every turn. Transgender people must of course lead any sort of initiatives to improve their lives, even as partnerships are needed to build capacity, translate lived experience into usable data, and to make strategic decisions. The SRHR of transgender people can only be addressed with attention to the social, cultural, legal, historical, and political contexts in which people are situated, with social, psychological, medical, and legal gender affirmation as a key priority shaping any intervention. Bringing together nine diverse yet complementary perspectives, our intent is to jumpstart a global and multigenerational conversation among transgender activists, lawyers, policy-makers, programmers, epidemiologists, economists, social workers, clinicians and all other stakeholders to help think through priority areas of focus that will support the needs, rights, and health of transgender populations. Making the changes envisioned here is possible but it will require not only the advocacy, policy, programmatic and research directions presented here but also struggle and action locally, nationally, and globally.
