An uncemented stem has been used successfully in total hip arthroplasty for 2 decades, and some implants have been updated. The authors have used second-generation uncemented proximal porous coating stems, the Echo Bi-Metric Full Proximal Profile stem (Echo FPP; Biomet, Warsaw, Indiana) and the Echo Reduced Proximal Profile stem (Echo RPP; Biomet). This article reports short-term outcomes with ...

This factorial study was carried out from 15/10/2020 to 31/6/2021 investigate the effect of chop length (CL) and level molasses (M) added at ensiling on chemical composition yellow corn stover including leaves stems. Those materials were chopped into 4 lengths, 5, 10, 15 20 mm as a source soluble carbohydrates 3 levels, 6, 8 10% dry matter (DM). Urea all samples 2% enhance nitrogen content. Sam...

The organized lignocellulosic assemblies of cell walls provide the structural integrity required for the large statures of terrestrial plants. Silencing two CINNAMYL ALCOHOL DEHYDROGENASE (CAD) genes in Nicotiana attenuata produced plants (ir-CAD) with thin, red-pigmented stems, low CAD and sinapyl alcohol dehydrogenase activity, low lignin contents, and rubbery, structurally unstable stems whe...

In this paper, to simulate mechanical stress on the cutter bar of the harvesting combine during cutting of wheat stems, first, shearing strength of the stems was measured for various moisture content levels and cutting heights. After that the cutter bar of combine was simulated by Abaqus with the specified conditions. The results of the simulation showed that with increase in moisture content o...

responded to those of proteins deduced from the CR6RP1 and -2 cDNAs. Immunohistochemical staining revealed that the CRGRPs accumulEted specifically in the lignified walls of metaxylem vessels in the root, stein and leaf and in the lignified cell walls of periyascu]ar fibers in cucumber stems. ImmunostHining was also detected in the walls of metaxylem yessels and in the ceLl walls of adjacent sc...

Pectin is the most abundant component of primary cell walls in eudicot plants. The modification and degradation of pectin affects multiple processes during plant development, including cell expansion, organ initiation, and cell separation. However, the extent to which pectin degradation by polygalacturonases affects stem development and secondary wall formation remains unclear. Using an activat...
