Intact chloroplasts of wheat (Triticum aestivum) were isolated from mesophyll protoplasts. With decreasing concentrations of bicarbonate from 10 to 0.3 millimolar (pH 8.0), the optimal concentration of orthophosphate (Pi) for photosynthetic O(2) evolution decreased from a value of 0.1 to 0.2 millimolar to 0 to 0.025 millimolar. The extremely low Pi optimum for photosynthesis at the low bicarbon...

background: in this study, we determined the serum levels of il-17a and il-10 in context with 1, 2 dihydroxy vitamin d3, parathormone and ca2+/pi ions to investigate their pathological or protective roles respectively in bone metabolism. methods: the bone mineral density (bmd) was determined for 1203 participants using energy x-ray absorptiometry. subjects with a history of diseases and using b...

Water scarcity leads to an increased use of reclaimed water, which in turn calls for an improvement in water reclamation procedures to ensure adequate quality of the final effluent. The presence of infectious Cryptosporidium oocysts (IOO) in reclaimed water is a health hazard for users of this resource. Here, we gathered information on Cryptosporidium (concentrations, infectivity and genotype) ...

Four new D-pi-D (or D-pi-D-pi-D) complexes 9-ethyl-3-E-((1-ferrocenyl)vinyl)-carbazole (1), 9-ethyl-3,6-E,E-((1,1-diferrocenyl)vinyl)- carbazole(2), 10-ethyl-3-E-((1-ferrocenyl)vinyl)-phenothiazine (3), 10-ethyl- 3,7-E,E- ((1,1-diferrocenyl)vinyl)-phenothiazine (4), have been obtained by solid-phase Wittig reactions and fully characterized. The four complexes were treated with iodine leading to...

Distortion of the upper airway by negative transmural pressure (UANP) causes reflex vagal bradycardia. This requires activation of cardiac vagal preganglionic neurons, which exhibit postinspiratory (PI) discharge. We hypothesized that UANP would also stimulate cranial respiratory motoneurons with PI activity. We recorded 32 respiratory modulated motor units from the recurrent laryngeal nerve of...

This study evaluates the validity of derived measures of the psychopathic personality traits of Fearless Dominance and Impulsive Antisociality from the NEO Personality Inventory-Revised (NEO-PI-R; Costa & McCrae, 1992) using data from the Collaborative Longitudinal Personality Disorders Study (baseline N = 733). These 3 issues were examined: (a) the stability of the measures over a 10-year inte...

Background: Fungal corneal ulcer is the most dangerous and challenging type of infective keratitis.  Since most of the ophthalmic antifungal drops are scarce and expensive in developing countries, attempts have been made to study fungicidal property of some readily available antiseptic agents as a substitute.  Povidone iodine (PI) and chlorhexidine gluconate (CHx) has been postulated to be effe...

3-Amino-1-propanol (AP), a substance replacing ethanolamine in phosphatidylethanolamine (PE) significantly reduced 32P incorporation to phosphatidylinositol (PI) and glycosyl-phosphatidylinositol (GPI) in the unicellular organism Tetrahymena pyriformis. At 10 mM, AP completely inhibited the incorporation of 32P into PI. 3H-arachidonate incorporation into PI was also inhibited, while that into d...

The Cabibbo-Kobayashi-Maskawa (CKM) matrix element $\vert V_{ub}\vert$ is obtained from exclusive semileptonic $B \to \pi \ell \nu_\ell$ and $B_s K decays adopting the unitarity-based dispersion approach for determination of hadronic form factors (FFs) in whole kinematical range. We use lattice computations relevant susceptibilities FFs large-$q^2$ regime order to derive their behavior low-$q^2...
