Factors affecting the respiratory control ratio of isolated rabbit heart mitochondria have been studied. The magnitude of the control ratio was shown to be affected by the presence of endogenous substrates, the nature of exogenous substrate, and the concentrations of mitochondria and of adenosine triphosphate. Higher control ratios were obtained in the presence of endogenous substrates and at a...

This study evaluated the occurrence and frequency of the anatomical variations of the origin and course of the posterior intercostal arteries (PIA) in 44 human cadavers. During a classical anatomical dissection of each cadaver an anomalous course of the PIA, defined as a thoracic vertebral artery, was found in six (14%) individuals. Every dorsally coursing PIA was taken into account, regardless...

Abstract Linear nonsaturating magnetoresistance (LMR) represents a class of anomalous resistivity response to external magnetic field that has been observed in variety materials including but not limited topological semi-metals, high- T c superconductors and with charge density wave (CDW)/spin orders. Here we report the observation LMR layered kagome superconductor CDW material CsV 3 Sb 5 thin ...

There are considerable variations in the anatomy of the human ophthalmic artery (OphA), such as anomalous origins of the OphA and anastomoses between the OphA and the adjacent arteries. These anatomical variations seem to attribute to complex embryology of the OphA. In human embryos and fetuses, primitive dorsal and ventral ophthalmic arteries (PDOphA and PVOphA) form the ocular branches, and t...

Self-compartmentalizing proteases orchestrate protein turnover through an original architecture characterized by a central catalytic chamber. Here we report the first structure of an archaeal member of a new self-compartmentalizing protease family forming a cubic-shaped octamer with D(4) symmetry and referred to as CubicO. We solved the structure of the Pyrococcus abyssi Pab87 protein at 2.2 A ...

Background: Ankylosing spondylitis (AS) may manifest with heterogeneous patterns according to ethnic origins. The objectives of this study were to describe the influence of various Iranian ethnic origins on clinical measures in patients with AS. Methods: 0ne hundred sixty-three AS patients diagnosed by modified New York 1984 criteria were enrolled consecutively in a cross-sectional study. The ...
