In this paper it is shown th a t such behaviour may be simply modelled based on the assumption of only single occupancy of the channel. W ith use of linear flux equations the calculated flux ratio is as measured. The additional assumption of single occupancy of the channel results in the calculated values of and J qut both being multiplied by the same factor, 1 —P ,where P is the probability th...
Invasive plants are recognized for their impressive abilities to withstand adverse environmental conditions however, all invaders do not express the similar abilities. Therefore, survival, growth, nutrient uptake and fecundity of two co-occurring, invasive Physalis species were tested under water and salinity stresses, and different soil textures in the current study. Five different water stres...
The electrogenic Na-K pump coupling ratio in the large neurons of the lobster cardiac ganglion was determined by two different electrophysiological techniques. A graphical analysis plotting exp(EmF/RT) vs. [K]o after the pump was blocked by ouabain was used to determine values for [K]i, PNa/PK, and the pump coupling ratio. These measurements were made 4-8 h after the cells were penetrated with ...
In order to investigate the effects of irrigation water salinity on root traits and absorption of sodium (Na+) and potassium (K+) by wheat cultivars, a factorial experiment, based on completely randomized design with 3 replications, was conducted under greenhouse conditions. The main factor was 7 wheat genotypes ]Ghods, Marvdasht and Bahar (sensitive to salinity) and Arg, Bam, Sistani and Sing...
BACKGROUND Tolvaptan is vasopressin type 2 receptor antagonist that inhibits water reabsorption. It is used in combination with standard diuretics to treat ascites unresponsive to standard diuretic therapy or hyponatremia because of liver cirrhosis. This study evaluated the effectiveness and safety of tolvaptan in clinical practice and aimed to determine the factors related to its effectiveness...
Data on coat colour pigmentation and incidence of wattle were combined with production records 1407 West African dwarf goats to study their influence litter traits body weight. There was no significant (P>0.05) difference among colours for size at birth weaning Basic white coloured significantly (P <0.05) heavier one year age than the basic brown black goats. The trend that weight decreas...
Background—The urinary composition including sodium (Na) and chloride (Cl) concentrations might provide useful information in addition to urine output during decongestive treatment in heart failure (HF). Methods and Results—Consecutive HF patients (n=61) with ejection fraction 45%, worsening symptoms, and scheduled treatment with intravenous loop diuretics were included. Patients received proto...
background: the aim of the study was to analyze the reliability of the korean version of the news and to investigate the relationship between walking and environmental factors by gender. methods: a total of 1407 korean adults, aged 20-59 yr, participated in the study. data were collected between sep 2013 and oct 2013. to examine the test-retest reliability, 281 of the 1407 participants were ask...
The properties of the small fraction of tetrodotoxin (TTX)-sensitive Na channels that remain open in the steady state were studied in internally dialyzed voltage clamped squid giant axons. The observed Ussing flux ratio exponent (n') of 0.97 plus minus 0.03 (calculated from simultaneous measurements of TTX-sensitive current and (22)Na efflux) and nonindependent behavior of Na current at high in...
The ratio of the effective number of breeders (Nb) to the adult census size (Na), Nb/Na, approximates the departure from the standard capacity of a population to maintain genetic diversity in one reproductive season. This information is relevant for assessing population status, understanding evolutionary processes operating at local scales, and unraveling how life-history traits affect these pr...
