The externalization of Phosphatidylserine (PS) from the inner surface of the plasma membrane to the outer surface of the plasma membrane is an emblematic event during apoptosis and serves as a potent "eat-me" signal for the efferocytosis of apoptotic cells. Although less well understood, PS is also externalized on live cells in the tumor microenvironment and on live virus-infected cells whereby it serves as an immune modulatory signal that drives tolerance and immune escape. Given the importance of PS in cancer immunology and immune escape, PS-targeting monoclonal antibodies have been characterized with promising immunotherapeutic potential.

Introduction: In response to continued public health emergency of antimicrobial resistance (AMR), a significant key strategy is the discovery of novel mycobacterial efflux-pump inhibitors (EPIs) as potential adjuvants in combination drug therapy. Interest in identifying new chemotypes which could potentially synergize with the existing antibiotics and can be deployed as part of a combination therapy. This strategy could delay the emergence of resistance to existing antibiotics and increase their efficacy against resistant strains of mycobacterial species.

Objectives: Whether vortioxetine has a utility as an adjuvant drug in the treatment of bipolar depression remains controversial. This study aimed to validate the efficacy and safety of vortioxetine in bipolar depression.
Methods: Patients with bipolar Ⅱ depression were enrolled in this prospective, two-center, randomized, 12-week pilot trial.
New Frontiers: Umbilical Cord Mesenchymal Stem Cells Uncover Developmental Roots and Biological Underpinnings of Obesity Susceptibility.

Section of Nutrition, Department of Pediatrics, University of Colorado Anschutz Medical Campus, Aurora, CO, USA.
Purpose Of Review: To review evidence supporting human umbilical cord mesenchymal stem cells (UC-MSC) as an innovative model system advancing obesity precision medicine.
Recent Findings: Obesity prevalence is increasing rapidly and exposures during fetal development can impact individual susceptibility to obesity. UC-MSCs exhibit heterogeneous phenotypes associated with maternal exposures and predictive of child cardiometabolic outcomes.

Lipophilic derivatives of vitamin C, known as ascorbyl-6-O-alkanoates (ASCn), have been mainly developed for use in cosmetics, pharmaceuticals, and the food industry as antioxidant additives. These derivatives are of biotechnological interest due to their antioxidant properties, amphiphilic behavior, capacity to self-organize into nano- and micro-structures, anionic nature, and low cost of synthesis. In this review, we will focus on the commercial amphiphile, 6-O-palmitoyl L-ascorbic acid (ASC16), and the shorter acyl chains derivatives, such as 6-O-myristoyl (ASC14) and 6-O-lauroyl L-ascorbic acid (ASC12).
