Developing and deploying cotton cultivars with high nutrient uptake, use efficiency and tolerance to nutrient related soil stresses is desirable to assist sustainable soil management. Genetic variation, heritability, selection response and quantitative trait loci (QTLs) were investigated for five macronutrients (P, K, Ca, Mg, S) and five micronutrients (Fe, Mn, B, Zn, and Cu) in a recombinant i...

BACKGROUND Re-endothelialization is delayed after drug-eluting stent (DES) implantation. In this setting, neointima is more prone to become lipid laden and develop neoatherosclerosis (NA), potentially increasing plaque vulnerability. METHODS AND RESULTS Optical coherence tomography and near-infrared spectroscopy with intravascular ultrasound were used to characterize NA in 65 (51 DES and 14 b...

The success of cellular therapies will depend in part on accurate delivery of cells to target organs. In dendritic cell therapy, in particular, delivery and subsequent migration of cells to regional lymph nodes is essential for effective stimulation of the immune system. We show here that in vivo magnetic resonance tracking of magnetically labeled cells is feasible in humans for detecting very ...

Huntington’s disease (HD) is initiated by an abnormally expanded polyglutamine stretch in the huntingtin protein, conferring a novel property on the protein that leads to the loss of striatal neurons. Defects in mitochondrial function have been implicated in the pathogenesis of HD. Here, we have examined the hypothesis that the mutant huntingtin protein may directly interact with the mitochondr...

The phosphorylated intermediate (EP) of the Na,K-ATPase proteoliposomes (PL) prepared from the electric eel enzyme is composed of an ADP-sensitive K+-insensitive form (E1P), an ADP- and K+-sensitive form (E*P), and a K+-sensitive ADP-insensitive form (E2P). The composition of the intermediate varied with the cholesterol content of the lipid bilayer. The PL containing less than 30 mol % choleste...

This paper describes experiments designed to evaluate Na(+) and Cl(-) transport in isolated proximal straight tubules from rabbit kidneys. When the perfusing solution was Krebs-Ringer buffer with 25 mM HCO(3) (-) (KRB) and the bath contained KRB plus 6% albumin, net volume reabsorption (J(v), nl min(-1) mm(-1) was -0.46 +/- 0.03 (SEM); V(e), the spontaneous transepithelial potential difference,...

background: many oral squamous cell carcinomas (osccs) arise within regions that previously had premalignant lesion. early diagnosis and prompt treatment of premalignant lesions offers the best hope of improving the prognosis in patients with oscc. exfoliative cytology is a simple and non-invasive diagnostic technique that could be used for early detection of oral premalignant and malignant les...

dry land salinity is one of the major problems affecting agricultural products. the main consequences of plant exposure to salt stress are water deficit and ion excess, which lead to several morphological and physiological changes. in order to evaluate the effect of salinity on some physiological characteristics of 8 spring rapeseed cultivars, an experiment was conducted in the greenhouse at ya...
