in this study, a simple and low-cost method was developed for extraction and pre-concentration of brilliant blue(bb) and tropaeolin o(to) in food samples using cloud point extraction (cpe) prior to spectrophotometric determination. the effects of main factors such as ph, surfactant and salt concentrations, incubation time and temperature on the cloud point extraction of both dyes were investiga...

Cholesterol synthesis inhibitors and fibrates both exercise effects that could influence BP and renal function in hypertension. To test this issue, transit-time ultrasound flow probes, implanted optical fibers, and laser-Doppler flowmetry were used for measurements of total and regional renal blood flows in lovastatin (40 mg/kg body wt) and bezafibrate (50 mg/kg body wt) chronically treated deo...

Dahl salt-sensitive rats fed a low salt diet demonstrate functional impairment in baroreflex control of cardiovascular function prior to the development of hypertension. The purpose of this study was to identify the mechanism(s) responsible for impaired baroreflex control in prehypertensive Dahl salt-sensitive rats. To examine the central and efferent portions of the baroreflex arc, we electric...

PURPOSE Effective imaging of human tissue with microwave tomography systems requires a matching fluid to reduce the wave reflections at the tissue boundary. Further, in order to match the idealized mathematical model used for imaging with the complicated physical measurement environment, loss must be added to the matching fluid. Both too little and too much loss result in low-quality images, bu...

Cyanobacteria are an important source of natural products. In this article, we briefly review the responses of cyanobacteria to different stresses. Abiotic stresses (temperature, salt, heavy metals, metalloid and ultraviolet (UV) influence cell growth and metabolism in cyanobacteria. Salt stress is a major abiotic factor that decrease...

Guava (Psidium guajava L.), is adapted to an extensive range of soils, however, its development is strongly affected by salinity. Environmental stresses are of the major and influential factors in the amount of secondary metabolites, especially phenolic compounds present in plants. The purpose of this investigation was to study the leaf antioxidant and flavonoid contents (catechin, quercetin an...

BACKGROUND AND AIMS The small leafy succulent shrub Halocnemum strobilaceum occurs in saline habitats from northern Africa and Mediterranean Europe to western Asia, and it is a dominant species in salt deserts such as those of north-west China. The effects of temperature, light/darkness and NaCl salinity were tested on seed germination, and the effects of salinity were tested on seed germinatio...

The importance of dietary salt may explain why bees are often observed collecting brackish water, a habit that may expose them to harmful xenobiotics. However, the individual salt preferences of water-collecting bees were not known. We measured the proboscis extension reflex (PER) response of Apis mellifera water foragers to 0-10% w/w solutions of Na, Mg and K, ions that provide essential nutri...

BACKGROUND Several studies pertaining to current status of Iodine Deficiency Disorder Control Programme in India have revealed goiter prevalence in the range of 1.5-44.5%, mean urinary iodine excretion level ranging from 92.5-160 mcg/L and iodized salt coverage ranging from 37-62.3%. Most of these studies were based on school children. However, very few studies have focused on pregnant women. T...

Background: In developing countries most of the edible salts have insufficient iodine content; the problem is worse in Africa. Only 15.4% of the Ethiopian population was using adequately iodized salt. Several factors affect iodine content of edible salt including poor handling practices. The existing evidence isn’t sufficient to detail the specific factors at the household level. Therefore, the...
