Evidence accumulated mitochondria, as the "powerplants of the cell," express several functional receptors for external ligands that modify their function and regulate cell biology. This review sheds new light on the role of these organelles in sensing external stimuli to facilitate energy production for cellular needs. This is possible because mitochondria express some receptors on their membranes that are responsible for their autonomous responses.

Background: Conventional post-stroke edema management strategies are limitedly successful as in multiple cases of hemorrhagic transformation is being reported. Clinically, acute-ischemic-stroke (AIS) intervention by endovascular mesenchymal stem cells (MSCs) have shown benefits by altering various signaling pathways. Our previous studies have reported that intra-arterial administration of 1*10 MSCs (IA-MSCs) were beneficial in alleviating post-stroke edema by modulating PKCδ/MMP9/AQP4 axis and helpful in preserving the integrity of blood-brain-barrier (BBB).

Purpose: The purpose of this study is to evaluate the influence of photobiomodulation therapy on the regenerative potential of non-vital mature permanent teeth of healthy Canine dogs.
Methods: 54 mature roots, obtained from 27 premolars, in dogs, were selected and divided into three equal groups where Group I received regenerative endodontic procedures (REPs) using blood clot as a scaffold (positive control), Group II received similar treatment as Group I, followed by photobiomodulation therapy (study group) and Group III did not receive any intervention (negative control). Each group was further divided into three equal subgroups for the evaluation of the vascular area percentage and fibroblast count at 3 different intervals; 3, 10, and 15 weeks.

Molecules of the tumour necrosis factor superfamily (TNFSF) are key players in immune regulation; an increase in some TNFSF molecules has been reported during severe COVID-19. In this study, we profiled and evaluated TNFSF members in the serum of COVID-19 vaccine-naïve patients to identify potential biomarkers associated with disease severity. Our data show that TRAIL serum levels are lower in severely affected patients than those mildly affected by COVID-19 (AUC 0.

Aim: Type 2 diabetes mellitus (T2DM) is a metabolic syndrome characterised by absolute or relative insufficiency of insulin secretion. The alkaloids from Rhizoma coptidis have potential hypoglycemic effects. Epiberberine (EPI), a protoberberine alkaloid extracted from Rhizome coptidis, has been found to regulate lipid metabolism.
