Hypercholesterolemia, high serum cholesterol in the form of LDL, is a major risk factor for atherosclerosis. LDL is mostly degraded in the liver after its cellular internalization with the LDL receptor (LDLR). This clathrin-mediated endocytosis depends on the protein autosomal recessive hypercholesterolemia (ARH), which binds the LDLR cytoplasmic tail. Mutations in either the LDLR tail or in AR...
پژوهش حاضر با هدف شناسایی توالی ژن laea، که یکی از اجزای کمپلکس ولوت می باشد، در قارچ p. brevicompactum انجام می شود. ابتدا ژن پروتئین laea با استفاده از روش tail-pcr شناسایی شده، سپس بررسی های بیوانفورماتیکی با استفاده از نرم افزارهای موجود در داده پایگاه های مختلف بر روی توالی بدست آمده انجام می گردد.
Charge exchange interactions of ions with the ablation cloud of an injected lowZ impurity pellet can be used to measure the energy spectrum and radial profile of confined fast ions in a fusion plasma. On TFTR, we use this technique to directly measure energetic alphas from D-T reactions, tritons from D-D reactions, and RFdriven minority tail ions (e.g., H, 3He, T). This paper describes the stat...
Focal adhesions mediate force transfer between ECM-integrin complexes and the cytoskeleton. Although vinculin has been implicated in force transmission, few direct measurements have been made, and there is little mechanistic insight. Using vinculin-null cells expressing vinculin mutants, we demonstrate that vinculin is not required for transmission of adhesive and traction forces but is necessa...
Calcium activates full-length myosin Va steady-state enzymatic activity and favors the transition from a compact, folded "off" state to an extended "on" state. However, little is known of how a head-tail interaction alters the individual actin and nucleotide binding rate and equilibrium constants of the ATPase cycle. We measured the effect of calcium on nucleotide and actin filament binding to ...
[1] On 31 March 2001 a fast solar wind transient with strong southward interplanetary magnetic field Bz produced a large geomagnetic storm at Earth, with a drop in the Dst index to 350 nT between 0400 and 0900 UT. The Earth’s magnetosphere was very compressed during this interval, with the bow shock crossing geosynchronous orbit on at least two occasions. Here we present space-based and ground-...
پیش بینی نرخ تورم در فرآیند سیاستگذاری اقتصادی از حساسیت زیادی برخوردار است و بر این اساس، بالا بردن دقت پیش بینی های کمی و تلفیق آن با معیارهای قضاوتی از ضروریات سیاستگذاری اقتصادی می باشد. این پژوهش در صدد مدلسازی و پیش بینی نرخ تورم با استفاده از مدل های غیر خطی سری زمانی می باشد. از این رو در این پژوهش ابتدا مدل های خطی ar و tgarch و egarch بهینه تخمین زده شدند. در ادامه با آزمون های bds و ...
Miners in underground coal mines experience prolonged exposure to high noise levels, often with A-weighted sound levels in excess of 90 dB. Field tests have shown that the continuous miner conveyor is a dominant noise source. This paper will identify the most significant noise-radiating surfaces on the continuous miner tail section using vibration levels and surface areas to estimate the sound ...
Inter-protein interactions in solution affect the auto-correlation function of Brownian tumbling not only in terms of a simple increase of the correlation time, they also lead to the appearance of a weak slow component ("long tail") of the correlation function due to a slowly changing local anisotropy of the microenvironment. The conventional protocol of correlation time estimation from the rel...
