grain hardness is one of the most important quality characteristics of cultivated bread wheat (triticum aestivum l.) that has main effect on milling yield, particle size, and water absorption of wheat flour. kernel hardness is mainly controlled by ha locus on the short arm of chromosome 5d in bread wheat. in this study, we have employed a multifaceted approach to investigate aspects of grain ha...
Ni-based superalloys are the important materials for gas turbines in advanced aeroplane engines . The addition of refractory elements to these superalloys, such as rhenium and tungsten, can significantly improve the hightemperature performance by so-called solid-solution hardening. Although the strengthening effect of refractory elements in Ni-based superalloys have been known for a long time, ...
Purpose: Alternative CCND1 splicing results in cyclin D1b, which has specialized, protumorigenic functions in prostate not shared by the cyclin D1a (full length) isoform. Here, the frequency, tumor relevance, and mechanisms controlling cyclin D1b were challenged. Experimental Design: First, relative expression of both cyclin D1 isoforms was determined in prostate adenocarcinomas. Second, releva...
Cortical neurons respond in a variety of ways to locally applied dopamine, perhaps because of the activation of different receptors within or among subpopulations of cells. This study was conducted to assess the effects of dopamine and the receptor subtypes that mediate the responses of a specific population of neurons, the pyramidal tract neurons (PTNs) in the rodent motor cortex. The specific...
Dopamine plays an important role in the regulation of renal sodium excretion. The synthesis of dopamine and the presence of dopamine receptor subtypes (D1A, D1B, as D1-like and D2, and D3 as D2-like) have been shown within the kidney. The activation of D1-like receptors located on the proximal tubules causes inhibition of tubular sodium reabsorption by inhibiting Na,H-exchanger and Na,K-ATPase ...
