BACKGROUND Actomyosin contractility is the major cellular force driving changes in cell and tissue shape. A principal regulator of contractility is the small GTPase RhoA. External mechanical forces have been shown to impact RhoA activity and cellular contractility. However, the mechanotransduction pathway from external forces to actomyosin contractility is poorly understood. RESULTS Here, we ...

CONCLUSIONS Time constant and maximum slow phase velocity (SPV) of head-shaking nystagmus (HSN) demonstrated a differential canal response to head shaking in 24% of patients with posterior canal benign paroxysmal positional vertigo (BPPV). We suggest that vestibular lithiasis has a limited contribution to the mechanism that generates HSN. OBJECTIVE To determine the canal response to head shak...

This paper presents the mathematical modeling of three-phase grid connected inverter fed by Solar Photovoltaic (SPV) system with Maximum Power Point Tracking (MPPT). Analysis has been carried out to choose the proper modulation index for maximum output for three-phase inverter. With this modulation index, the variation of the active and reactive power for different loads has been presented alon...

DNA sequence assembly problem is a very complex problem of computational biology. DNA sequence assembly is a NP hard problem there is no single solution available for this kind of problems. DNA sequence assembly refers to aligning and merging fragments of a much longer DNA sequence in order to reconstruct the original sequence. In this paper a solution is proposed for DNA sequence assembly prob...

We present a partial parser called TeLePaPa (TextLens Partial Parser) to identify subjects and predicate verbs (SPVs) in a sentence of abstracts of MEDLINE citations. The performance of TeLePaPa is the precision of 96.7% and 97.1% for the SPV detection, respectively, and the recall of 91.3% and 94.9%, respectively. We found that there was a similarity in the distribution of the pairs of SPV ove...

Photoelectron spectroscopy ~PES! has been used to measure the dependence of core-level shifts on temperature T and source intensity for the clean ~0001! surfaces of pand n-GaN grown by metalorganic chemical vapor deposition. In the dark, the Fermi level at the surface occurs 2.55 eV above the valence band maximum for both carrier types. The surface photovoltage ~SPV! induced by laboratory PES s...

OBJECTIVE Stentless aortic valves are widely used due to their excellent hemodynamic properties. However, if the subcoronary implantation technique is used later dilatation of the sinotubular junction (STJ) can cause regurgitation. The aim of the study was to determine the dilatation tolerance of two commercially available stentless xenografts and fresh aortic and pulmonary roots against such d...

sheeppox virus (spv) and goatpox virus (gpv) belong to the capripoxvirus genus of poxviridae family. sheeppox and goatpox along with contagious ecthyma (ce) are endemic diseases in iran. capripox laboratory conformation based on virological and serological techniques are time consuming, laborious and most of them of low specificity, because of close antigenic relationship between capripoxvirus ...

Smectites are the most commonly found clay mineral in many temperate region soils.It exhibits variability in shrink – swell behavior and sorption of organic molecules. Previousresearch has established the relationship between extent of swelling and sorption of organiccompounds by smectites. The effect of the interlayer cation on sorption of organiccompounds and the inter-rel...
