Core-shell model of the clusters of CPEB4 isoforms preceding liquid-liquid phase separation.

Protein solutions can undergo liquid-liquid phase separation (LLPS), where a dispersed phase with a low protein concentration coexists with coacervates with a high protein concentration. We focus on the low complexity N-terminal domain of cytoplasmic polyadenylation element binding-4 protein, CPEB4, and its isoform depleted of the Exon4, CPEB4Δ4. They both exhibit LLPS, but in contrast to most systems undergoing LLPS, the single-phase regime preceding LLPS consists mainly of soluble protein clusters.

Ebola Virus Glycoprotein Strongly Binds to Membranes in the Absence of Receptor Engagement.

Ebola virus (EBOV) is an enveloped virus that must fuse with the host cell membrane in order to release its genome and initiate infection. This process requires the action of the EBOV envelope glycoprotein (GP), encoded by the virus, which resides in the viral envelope and consists of a receptor binding subunit, GP1, and a membrane fusion subunit, GP2. Despite extensive research, a mechanistic understanding of the viral fusion process is incomplete.

Gender Comparisons of Surgical Outcomes in Patients Undergoing One Anastomosis Gastric Bypass (OAGB): a Historical Cohort Study.

Introduction And Purpose: Clinical trials in the field of bariatrics have frequently been gender imbalanced, with males representing only 20% of examinees. Long-term gender-oriented results in one anastomosis gastric bypass (OAGB), and specifically quality of life (QOL) parameters, have not been addressed sufficiently. A better understanding of gender's effect on OAGB outcomes can play an important role in selecting the appropriate bariatric surgery for patients.

Membrane Tension Inhibits Lipid Mixing by Increasing the Hemifusion Stalk Energy.

Fusion of biological membranes is fundamental in various physiological events. The fusion process involves several intermediate stages with energy barriers that are tightly dependent on the mechanical and physical properties of the system, one of which is membrane tension. As previously established, the late stages of fusion, including hemifusion diaphragm and pore expansions, are favored by membrane tension.

The use of Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) in Civilian Trauma in an Israeli Level 1 Trauma Center.

Background: Massive, non-compressible bleeding is a leading cause of preventable trauma mortality. Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) is a minimally invasive procedure in which a balloon catheter is maneuvered into the aorta to temporarily occlude large vessels and enable stabilization of the exsanguinating patient.

Objectives: To present experiences in assimilating REBOA at a single level 1 trauma center in Israel, to evaluate the technical aspects of the procedure, and to describe patient characteristics and outcomes.
