Using transferred cross-correlated relaxation and DFT calculations, the conformation of the relevant conformation of N5,N10-methylenetetrahydromethanopterin, a reaction intermediate bound to the 80 kD H2-forming N5,N10-methylenetetrahydromethanopterin dehydrogenase is determined. The conformation of the intermediate differs from the free form in solution and makes the reaction mechanism plausible.

The orphan nuclear receptor Nur77/N10 has recently been demonstrated to be involved in apoptosis of T cell hybridomas. We report here that chronic expression of Nur77/N10 in thymocytes of transgenic mice results in a dramatic reduction of CD4+CD8+ double-positive as well as CD4+CD8and CD4-CD8+ single-positive cell populations due to an early onset ofapoptosis. CD4-CD8double-negative and CD25+ p...

The gas-phase acidities of adenine, 9-ethyladenine, and 3-methyladenine have been investigated for the first time, using computational and experimental methods to provide an understanding of the intrinsic reactivity of adenine. Adenine is found to have two acidic sites, with the N9 site being 19 kcal mol(-1) more acidic than the N10 site; the bracketed acidities are 333 +/- 2 and 352 +/- 4 kcal...

Introduction: The purpose of the present study was to evaluate anthropometric characteristics of weight, sitting & standing height, cormic index and BMI in the adult residents of Qazvin, Iran. Methods: In this cross-sectional study, 300 adult inhabitants aged 18-55 years (180 males and 120 females) of Qazvin, Iran were evaluated. The participants were selected randomly and without any physic...

This is a review of recently published papers showing that bone-conducted vibration of the head causes linear acceleration stimulation of both inner ears and this linear acceleration is an effective way of selectively activating otolithic afferent neurons. This simple stimulus is used in a new test to evaluate clinically the function of the otoliths of the human inner ear. Single neuron studies...

The development of airways hyperreactivity in allergic IL-13(-/-) mice is controversial and appears to correlate with the number of times that the original 129 x C57BL/6 founder strain has been crossed to the BALB/c background. In this investigation, we compared allergic responses in founder IL-13(-/-) mice crossed for either 5 (N5) or 10 (N10) generations to BALB/c mice. Whereas allergic N5 IL...

background: the appropriate designing of school equipment for establishing a suitable sitting habit, is of major importance. unfortunately, benches and desks in iranian schools are not properly adjusted with anthropometric characteristics of students. the main theme of this research is preparing some guidelines for anthropometric designing and ergonomic adjustment of benches and desks. methods:...
