Some evidence concerning the influence of various ions upon the fluxes and net uptake of sodium by the aquatic larva of Aides aegypti was described in an earlier paper (Stobbart, 1965). One of the main findings was that chloride in the external medium has, in concentrations up to 5 mM/1., a marked stimulatory effect upon sodium influx and net uptake. While the sodium pump (which occurs mainly i...

Sodium-rich myometrium, obtained from the uteri of pregnant rats, rapidly hyperpolarized when 4.6-120 mM potassium was added to the bathing medium at 37 degrees C. Hyperpolarization was due to sodium pumping since the process was markedly temperature dependent, was abolished by ouabain, and required both intracellular sodium and extracellular potassium. The observed membrane potential exceeded ...

The cincho artisanal cheese was dehydrated at drying temperature (50 °C, 55 °C and 60 °C), air velocity (0 m/s, 0.5 1 m/s), particle size (0.5 mm, 25 50 mm). final moisture content water activity values of dried ranged from 2.74 % to 4.67 0.23 0.43, respectively.  microbiological analysis raw sample showed the presence total coliform microorganisms (5.15 log FCU), molds yeasts (4.99 lactob...

A strain of Bacillus designated TA2.A1, isolated from a thermal spring in Te Aroha, New Zealand, grew optimally at pH 9.2 and 70 degrees C. Bacillus strain TA2.A1 utilized glutamate as a sole carbon and energy source for growth, and sodium chloride (>5 mM) was an obligate requirement for growth. Growth on glutamate was inhibited by monensin and amiloride, both inhibitors that collapse the sodiu...

OBJECTIVE - To ascertain whether restriction of dietary sodium lowers blood pressure in hypertensive and normotensive individuals. DATA SOURCES - An English-language computerized literature search, restricted to human studies with Medical Subject Heading terms, "hypertension," "blood pressure," "vascular resistance," "sodium and dietary," "diet and sodium restricted," "sodium chloride," "clin...

introduction: salinity is the most significant abiotic factor limiting crop productivity and several physiological responses, including modification of ion balance, water status, mineral nutrition, stomatal behavior, photosynthetic efficiency and so on. the gf677 (prunuspersica×prunusamygdalus) is widelyusedas rootstock for peach and almond. it is mainly used as a rootstock because of its resis...

Objective: The aim of this study was to compare the postoperative analgesic effects of preoperative intravenous (i.v.) paracetamol, diclofenac sodium and lornoxicam (nonsteroidal anti-inflammatory drugs). Subjects and Methods: Sixty patients with impacted third molar who underwent surgical removal were randomly allocated into three groups: group P (n = 20), group D (n = 20) and group L (n = 20)...

If filtration is required, sintered-glass funnels should be used as filter paper removes some of the dye by adsorption. Sodium bromide is used in preference to sodium chloride or potassium chloride because the detergent solution gradually develops a turbidity (not visible in the presence of the dye) on addition of the chlorides, and precipitates are formed on storage in mixtures of detergent, a...

TEIGER, D., F. ScHEwzR AND A. FARAH: The effects of sodium ion and rate of stimulation on the refractory period of isolated rabbit atrial muscle. J. Pharmac. exp. Ther. 155: 58-68, 1967. Variations in sodium ion concentration and rate of stimulation influence the effective refractory period of rabbit atrial musde. Thus sodium chloride concentrations higher than normal and an increase in rate of...
