Background: Hypothyroidism (HT), a relatively common condition among general population is associated with lipid profile abnormalities. The present study was designed to determine the contributive role of HT in the development of hypercholesterolemia (HCH). Methods: One hundred thirty six consecutive patients with HT and 272 euthyroid controls entered the study. Serum total cholesterol (CH) lev...

Tandem calponin-homology (CH) domains are the most common actin-binding domains in proteins. However, structural principles underlying their function are poorly understood. These tandem domains exist in multiple conformations with varying degrees of inter-CH-domain interactions. Dystrophin and utrophin tandem CH domains share high sequence similarity (∼82%), yet differ in their structural stabi...

We present the discovery in TMC-1 of vinyl acetylene, CH 2 CHCCH, and detection, for first time a cold dark cloud, HCCN, HC 4 N, 3 CN. A tentative detection CCH is also reported. The column density acetylene (1.2 ± 0.2) × 10 13 cm −2 , which makes it one most abundant closed-shell hydrocarbons detected TMC-1. Its abundance only three times lower than that propylene, CHCH . densities derived HCC...

Methyl, methyl-d(3), and ethyl hydroperoxide anions (CH(3)OO(-), CD(3)OO(-), and CH(3)CH(2)OO(-)) have been prepared by deprotonation of their respective hydroperoxides in a stream of helium buffer gas. Photodetachment with 364 nm (3.408 eV) radiation was used to measure the adiabatic electron affinities: EA[CH(3)OO, X(2)A' '] = 1.161 +/- 0.005 eV, EA[CD(3)OO, X(2)A' '] = 1.154 +/- 0.004 eV, an...

X-ray photoelectron and electron energy loss spectroscopic (XPS-EELS) studies reveal that the following species are present when a mixture of CO2 and water vapour is exposed to the clean Mg(100) surface at 110K: CO3(a), C(a) CH(a), OH(a). The reactive chemisorptions of CO2 and H2O vapour coadsorbed on a Mg surface ...

residual microorganisms in the root canal system (rcs) after endodontic therapy such as candida albicans are a major cause of endodontic failure. calcium hydroxide (ch) and chlorhexidine (chx) have suitable antimicrobial activity against bacteria and can be used as intracanal medicaments. nanosilver has also shown antimicrobial activity against microorganisms. this study aimed to compare the an...

In this work, NdFeO3 nanoparticles were synthesized through a simple co-precipitation method. The formation of NdFeO3 particles was verified by X-ray powder diffraction, infrared spectroscopy, vibrating sample magnetometer, and transmission electron microscopy analysis. Polyaniline and chitosan were employed as proper support for production of metal nanoparticles. Novel Pt...
