Tissue-specific endothelial cells (ECs) are critical for the homeostasis of pancreatic islets and most other tissues. In vitro recapitulation of islet biology and therapeutic islet transplantation both require adequate vascularization, which remains a challenge. Using human reprogrammed vascular ECs (R-VECs), human islets were functionally vascularized in vitro, demonstrating responsive, dynamic glucose-stimulated insulin secretion and Ca influx.

Current research aimed to isolate and identify the cadmium-reducing bacteria from contaminated coastal sediment in Karangsong Port, Indramayu, Indonesia. The isolates were investigated for their potential to reduce cadmium and showed the cadmium reduction drastically up to 50% at 6 hrs treated under different cadmium concentrations of 0, 5, 1 and 1.

Onsite non-potable water reuse systems (ONWS) are decentralized systems that treat and repurpose locally collected waters ( greywater or combined wastewater) for uses such as irrigation and flushing toilets. To ensure that treatment is meeting risk benchmarks, it is necessary to monitor the efficacy of pathogen removal. However, accurate assessment of pathogen reduction is hampered by their sporadic and low occurrence rates in source waters and concentrations in treated water that are generally below measurement detection limits.

Bone defects are a prevalent issue resulting from various factors, such as trauma, degenerative diseases, congenital disabilities, and the surgical removal of tumors. Current methods for bone regeneration have limitations. In this context, the fusion of tissue engineering and microfluidics has emerged as a promising strategy in the field of bone regeneration.

Melatonin, a molecule with diverse biological functions, is ubiquitously present in living organisms. There is significant interest in understanding melatonin signal transduction pathways in humans, particularly due to its critical role in regulating the sleep-wake cycle. However, a knowledge gap remains in fully elucidating the mechanisms by which melatonin influences circadian regulation.
