The Maximum Aerobic Capacity Effects Assessment and the Hand Power Perceived Exertion Rating

open access: yesInternational Journal of Occupational Hygiene, 2019
Grip and pinch strength are the most important factors affecting the hand’s performance. This study was aimed to evaluate the relationship between maximum aerobic capacity (Vo2max) and to rate the perceived exertion (RPE) with grip, pinch strength and ...

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

The temperature variation of the maximum oxygen uptake and time to exhaustion in the spinning factory workers [PDF]

open access: yesطب کار, 2013
Background: Fatigue is an important inhibiting factor in human performance, so with rising aerobic power could be overcome individual fatigue. Based on the importance of maximum oxygen consumption at fatigue threshold, the purpose of this study was to ...

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

open access: yesFEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

An interpretation of data after performing Step-rate-test in multi-layered, unconsolidated and weakly consolidated reservoirs

open access: yesИзвестия высших учебных заведений: Нефть и газ
The prerequisite for this study is the difficulty in interpreting data after stimulation of the bottomhole formation zone has been carried out. The objectives of this work are the applicability and interpretation of Step-rate-test (SRT) data to evaluate ...
