Regulation of Peptide Liquid-Liquid Phase Separation by Aromatic Amino Acid Composition.

Membraneless organelles are cellular biomolecular condensates that are formed by liquid-liquid phase separation (LLPS) of proteins and nucleic acids. LLPS is driven by multiple weak attractive forces, including intermolecular interactions mediated by aromatic amino acids. Considering the contribution of π-electron bearing side chains to protein-RNA LLPS, systematically study sought to how the composition of aromatic amino acids affects the formation of heterotypic condensates and their physical properties.

Emergent properties of melanin-inspired peptide/RNA condensates.

Most biocatalytic processes in eukaryotic cells are regulated by subcellular microenvironments such as membrane-bound or membraneless organelles. These natural compartmentalization systems have inspired the design of synthetic compartments composed of a variety of building blocks. Recently, the emerging field of liquid-liquid phase separation has facilitated the design of biomolecular condensates composed of proteins and nucleic acids, with controllable properties including polarity, diffusivity, surface tension, and encapsulation efficiency.

[DR. ARIEH LEIB SHIMONI-MEKLER - EYE, EAR, NOSE AND THROAT SPECIALIST].

Although the inauguration of the new hospital in Zefat built by Baron Rothschild took place in 1910, the building was not used as a hospital until World War I when it was confiscated by the Turks for patients affected with typhus, and later it was converted into a military hospital. The second inauguration of the renewed hospital was in June 1919, and the medical activity was assigned to the American Zionist Medical Unit for Palestine' (AZMU), later - 'Hadassah Medical Organization'. Among the first doctors that were sent to Zefat by AZMU was Dr.

Opiate Analgesics and the Perioperative Management of Patients with Obstructive Sleep Apnea.

As the rate of obesity and subsequently obstructive sleep apnea (OSA) continue to rise in North America and prescriptions for narcotic analgesics number in the tens of millions, it has become increasingly important to understand the interaction between OSA and opiate analgesics. Understanding the mechanism of action of opiate analgesics and the pathophysiology of OSA can help medical professionals understand the unique risks associated with pain management in this population of patients.

Long-term outcome of patients with antiphospholipid syndrome who undergo percutaneous coronary intervention.

Objectives: Patients with antiphospholipid antibody syndrome (APS) have an increased risk of atherothrombotic complications. There are limited data regarding the outcome of patients with APS who undergo percutaneous coronary intervention (PCI). Accordingly, we aimed to assess the long-term outcomes of these patients.
