Mechanosensitive channels sense and respond to changes in bilayer tension. In many respects, this is a unique property: the changes in membrane tension gate the channel, leading to the transient formation of open non-selective pores. Pore diameter is also high for the bacterial channels studied, MscS and MscL. Consequently, in cells, gating has severe consequences for energetics and homoeostasi...

This study compares the functional capabilities of different metacarpal fixation constructs under physiological loadings in an attempt to identify the optimal construct rather than the strongest one. One hundred and twenty-six preserved human metacarpals were mechanically tested after oblique osteotomies and internal fixation. Maximum load to failure, average structural rigidity, and energ...

Phenylketonuria (PKU) is a hereditary metabolic disorder which is caused by complete or near complete deficiency of phenylalanin hydroxylase or other cofactors of the phenylalanin metabolic cycle. In this paper the data are collected from 312 patients who were referred to Shahid Akbarabadi Hospital . These patients were the result of 215 marriages which were familial in 192 instances. Most of t...

The use of lightweight and cheap UAVs to detect the health of forests and identify the tension of planted can be useful to prevent the spread of pests and diseases. In the present research, a lightweight quadcopter drone with a 12-megapixel camera, visible light range was used. This UAV was emploied to detect leaf tension of pure Quercus Castanifolia plantation, pure Acer Velutinum and their mi...

in this research, the effect of tension wood formation in populus nigra on its anatomical characteristics was studied. vessel element and ray frequency (n/mm²), vessel diameter and ray dimensions were measured in both normal and tension wood. furthermore, the formation of gelatinous layer (g-layer) in the fibers of tension wood was studied. the results showed that the vessel proportion and diam...
