Micelle-enabled bromination of α-oxo ketene dithioacetals: mild and scalable approach enzymatic catalysis.

The bromination of α-oxo ketene dithioacetals using KBr/HO, catalyzed by vanadium chloroperoxidase (VCPO), has been successfully demonstrated. A comparative study of enzymatic processes "on water" "in water", using 2 wt% of the surfactant TPGS-750-M revealed that the in-water protocol not only provides higher yields but also accommodates a broader substrate scope. This bromination method in an aqueous micellar medium enabled the preparation of brominated α-oxo ketene dithioacetals in fair to excellent yields (23 examples).

Transferrin Disassociates TCR from CD3 Signaling Apparatus to Promote Metastasis.

Immune recognition and activation by the peptide-laden major histocompatibility complex-T cell receptor (TCR)-CD3 complex is essential for anti-tumor immunity. Tumors may escape immune surveillance by dissembling the complex. Here, we report that transferrin, which is overexpressed in patients with liver metastasis, disassociates TCR from the CD3 signaling apparatus by targeting the constant domain (CD) of T cell receptor α (TCRα), consequently suppresses T cell activation, and inhibits anti-metastatic and anti-tumor immunity.

Blarcamesine for the treatment of Early Alzheimer's Disease: Results from the ANAVEX2-73-AD-004 Phase IIB/III trial.

Background: There are no approved oral disease-modifying treatments for Alzheimer's disease (AD).

Objectives: The objective of this study was to assess efficacy and safety of blarcamesine (ANAVEX®2-73), an orally available small-molecule activator of the sigma-1 receptor (SIGMAR1) in early AD through restoration of cellular homeostasis including autophagy enhancement.

Design: ANAVEX2-73-AD-004 was a randomized, double-blind, placebo-controlled, 48-week Phase IIb/III trial.

Utility of Abdominal Radiographs After Posterior Spinal Fusion for Neuromuscular Scoliosis.

Postoperative ileus, the temporary cessation of gastrointestinal motility leading to accumulation of fluid and gas in the bowel, is a common complication following posterior spine fusion (PSF) in patients with neuromuscular scoliosis (NMS). Abdominal radiographs (KUBs) are often ordered to differentiate between ileus and mechanical obstruction but expose patients to radiation, add cost, and may lead to unnecessary work up. The aim of this study was to determine how often KUBs led to a change in treatment after PSF in patients with NMS.
