Advanced Healthcare Materials, EarlyView.Electrospun tubular scaffolds from novel PBCE‐based copolyesters and blends were designed as candidates for small‐diameter vascular grafts. They combine defect‐free architecture, blood‐compatible surfaces, and mechanical properties comparable to native vessels.

Social Security System in India: An International Comparative Analysis [PDF]
This paper examines selected components of social security system in India and compares them with their OECD counterparts. Historically, the Indian policy makers have viewed the pension system as a welfare measure and therefore, it lacks in financial ...

Advanced Healthcare Materials, EarlyView.This review highlights recent advances in smart face masks that actively monitor breathing. By integrating humidity, gas, temperature, pressure, strain, and triboelectric sensors, these masks track key respiratory parameters in real time. The article summarizes sensor mechanisms, compares performance across studies, and discusses challenges and future ...

Advanced Healthcare Materials, EarlyView.ABSTRACT Magnetogenetic deep brain stimulation (MG‐DBS) represents a wireless neuromodulation that has demonstrated long‐lasting behavioral benefits in Parkinson's disease models. However, the circuit‐level mechanisms underlying these therapeutic effects have remained uncharacterized due to limitations of conventional neural interfaces.

Advanced Healthcare Materials, EarlyView.ABSTRACT In vitro arterial models offer ethical and robust alternatives for vascular research but require cytocompatible materials that replicate physiological mechanics. Poly(vinyl alcohol) (PVA) hydrogels produced by directional freezing and salting‐out (PVA DFSO) are anisotropic yet lack stability for cell culture. Herein, methacrylated PVA (PVA‐MA)

Advanced Healthcare Materials, EarlyView.A superhydrophobic 3D cell culture platform enables rapid and consistent formation of heterotypic tumor–stroma clusters, and reveals how physiological shear conditions influence metastatic signaling. Mechanical stimulation of cancer‐associated fibroblasts promotes sustained cytokine secretion and survival‐promoting pathways, showing how multicellular ...
