Plants use the same set of co-receptors to mediate distinct responses to external signals. Brassinosteroid signaling serves as a test case to unravel the mechanisms of receptor-co-receptor activation and initiation of a specific signaling cascade.

Objectives: Drug injection carries with it many risks and therefore it is important to understand the initiating factors of injection and its origins. Thus,  the purpose of this study was to identify factors associated with the initiation of injection drug use among substance abusers. Methods:  Study method was a cross-sectional study. The research statistics universe constitutes a...

Hydrogen-assisted crack growth of pre-strained twinning-induced plasticity (TWIP) steel was investigated using artificial defects (micro-drilled holes), which acted as initiation sites. Hydrogen introduced into the specimens by electrochemical hydrogen charging during slow strain rate tensile test. The quasi-cleavage propagation observed due to repeated near tip and subsequent coalescence. Crac...

While the diagnostic properties of the TB LAM urine assay (LAM) have been well-described, little is known about its predictive and prognostic properties at ART initiation in a routine clinic setting. We describe the predictive and prognostic properties of LAM in HIV-positive patients initiating ART at an urban hospital in Johannesburg, South Africa. Retrospective study of HIV-positive adults (>...

A premature failure mode in steel rolling element bearings called white structure flaking (WSF) occurs in wind turbine gearbox bearings. WSF can occur in as little as 6-24 months of operation. WSF is associated with microstructural alterations called white etching area (WEA) and white etching cracks (WECs) that form in the ~1 mm zone beneath the contact surface. The tribological drivers for WSF...

objective: methanol extract of bran and unpolished grain of two traditional aromatic rice genotypes viz. kalijira and chinigura were assayed for their activity on the growth and initiation of crown-gall tumors on potato disks. materials and methods: three agrobacterium tumefaciens (a. tumefaciens) strain atsl0105, atta0112, and atac0114 were used as the tumor forming agent. collected rice was s...

conclusions the results showed that the effect of several psychosocial, behavioral, and demographic risk factors on adolescents' smoking status. thus, design and implementation of interventions based on the results of the present study may be effective in preventing tobacco smoking among adolescents. patients and methods this cross-sectional study was performed on 810 male adolescents recruited...

eIF3 promotes translation initiation, but relatively little is known about its full range of activities in the cell. Here, we employed affinity purification and highly sensitive LC-MS/MS to decipher the fission yeast eIF3 interactome, which was found to contain 230 proteins. eIF3 assembles into a large supercomplex, the translasome, which contains elongation factors, tRNA synthetases, 40S and 6...
