To elucidate the purpose of butterfly puddling, we measured the amounts of Na+, K+, Ca2+, and Mg2+ that were absorbed or excreted during puddling by male Japanese Papilio butterflies through a urine test. All of the butterflies that sipped water with a Na+ concentration of 13 mM absorbed Na+ and excreted K+, although certain butterflies that sipped solutions with high concentrations of Na+ excr...

Na+/K(+)-ATPase activity was demonstrated in the midgut of Anopheles stephensi. More than 80% of the total ATPase activity was sensitive to inhibition by ouabain with an IC50 of 4.5 x 10(-7) +/- 0.3 x 10(-7) mol l-1 and with maximal inhibition occurring at 10(-4) mol l-1. This ouabain-sensitive Na+/K(+)-ATPase was maximally activated at a Mg2+:ATP ratio of 1:1.3, with a Km of 0.3 mmol l-1 and a...

an experiment was conducted in algerian desert goats to study the effect of age and season on blood biochemical and mineral profile during different physiological stages of the goats. serum ca, mg and na levels were significantly high at birth and decreases as the age advanced. the season had a significant effect on the decreased levels of ca, mg and k and inversely on the increased levels of n...

Mg-extrusion from Mg-loaded neurons of the leech, Hirudo medicinalis, is mediated mainly by Na/Mg antiport. However, in a number of leech neurons Mg is extruded in the nominal absence of extracellular Na, indicating the existence of an additional, Na-independent Mg transport mechanism. This mechanism was investigated using electrophysiological and microfluorimetrical techniques The rate of Na-i...

BACKGROUND It is uncertain whether higher doses of selective serotonin reuptake inhibitors have greater efficacy in generalised anxiety disorder. AIMS To assess the efficacy of different doses of escitalopram in generalised anxiety disorder. METHOD Randomised, double-blind, placebo-controlled, fixed-dose, parallel-group, 12-week study, with 681 patients: placebo (n=139); escitalopram, 5 mg/...

soil salinity affects ions concentrationss of plant tissues and this may alter the merits quality of medicinal plants. experiments were conducted during 2003 at the the isfahan university of technology campus, isfahan, iran, to assess the effects of five soil salinity levels (3.2, 3.6, 4.5, 5.4 and 7.5 ds m-1) on na, k, and ca contents of borage and echium. each plant species was studied in a s...

The efflux of Mg++ from squid axons subject to internal solute control by dialysis is a function of ionized [Mg], [Na], [ATP], and [Na]o. The efflux of Mg++ from an axon with physiological concentrations of ATP, Na, and Mg inside into seawater is of the order of 2-4 pmol/cm2s but this efflux is strongly inhibited by increases in [Na]i, by decreases in [ATP]i, or by decreases in [Na]o. The efflu...

Aim: To describe the clinical data and disease severity of thoracic malignancy patients with COVID-19 its relation to mitigation process at Dharmais National Cancer Center, Indonesia.
 Methods: Total 5256 cancer registered from May 2020 March 2021. There were 681 diagnosed COVID-19. Forty-five enrolled. Data medical records obtained Hospital, then analyzed using SPSS version 25. Comparativ...

INTRODUCTION Demographic and disease characteristics may impact response to psoriasis therapies. The objective of this study is to explore the safety and efficacy profile of secukinumab in North American (NA) versus non-NA patients with moderate to severe psoriasis. METHODS Data were pooled from four phase 3 studies of secukinumab. Secukinumab (300 and 150 mg) was administered at baseline, we...
