We observed the effect of body mass index (BMI) on pregnancy outcomes in Chinese patients undergoing assisted reproductive treatment (ART). All the patients were divided into polycystic ovary syndrome (PCOS) group and non-PCOS group, and then according to BMI, each group was subdivided into 6 subgroups: group 1 (BMI < 18 kg/m2), group 2 (18-20 kg/m2), group 3 (20-22 kg/m2), group 4 (22-24 kg/m2...

In this paper, we perform a general reduction of an M2-brane on space–time that admits null Killing vector leading to fundamental string and D2-brane action in Newton–Cartan background.

The influenza A virus M2 polypeptide is a small integral membrane protein that does not contain a cleaved signal sequence, but is unusual in that it assumes the membrane orientation of a class I integral membrane protein with an NH2-terminal ectodomain and a COOH-terminal cytoplasmic tail. To determine the domains of M2 involved in specifying membrane orientation, hybrid genes were constructed ...

We have investigated protein-protein interactions among the respiratory syncytial virus (RSV) RNA polymerase subunits using affinity chromatography. Here we demonstrate a novel interaction of P and M2-1 proteins. Phosphorylation of either M2-1 or P appears to be dispensable for this interaction. Internal deletions within P mapped the M2-1-binding domain to a region between residues 100 and 120....

BACKGROUND Expression of the dimeric M2 isoenzyme of pyruvate kinase, termed Tumor M2-PK, is increased in some human cancers. This study evaluates the potential role of pre-operative Tumor M2-PK as a marker of prognosis in patients with pancreatic malignancy. METHODS Seventy-three consecutive patients with a clinical diagnosis of pancreatic or peri-ampullary cancer were enrolled. Their median...
