Isometric tension and isotonic shortening were measured at constant levels of calcium activation of varying magnitude in mechanically disrupted EGTA-treated ventricular bundles from guinea pigs. The results were as follows: (a) The effect of creatine phosphate (CP) on peak tension and rate of shortening saturated at a CP concentration more than 10 mM; below that level tension was increased and ...
Forty computer.simulated populations were analysed to derive fonnulae for estimating den.5ity of populations from a set of distances from sample points to the nearest member, from that member to its neighbour and from that neighbour to its nearest neighbour. Distances may be truncated or unlimited. The formulae were applied to data from 11 paper.dot and 18 field populations in a total of 37 exp...
OBJECTIVE To examine the impact of pregnancy on adolescent growth and adiposity relative to nulligravidas of similar maturation stage. DESIGN Prospective cohort study. SETTING The multicenter National Heart, Lung and Blood Growth and Health Study with annual examinations from 1987-1988 through 1996-1997. PARTICIPANTS One thousand eight hundred ninety girls (983 black and 907 white) aged 9...
Background & Objective: Mixed outcomes arise when, in a multivariate model, response variables measured on different scales such as binary and continuous. In a bivariate modeling, when there are mixed response variables, the common methods in classic statistics have shortcomings. This study aimed at designing an appropriate ANN model for modeling and predicting the bivariate mixed responses i...
This experiment was designed to study the effect of insulin like growth factor-I (IGF-I) on cryopreservation of Hariana bull semen. For this purpose, semen ejaculates were collected from four Hariana bulls using artificial vagina at biweekly interval. The semen samples which possess more than 70% initial progressive motility and above 500 million/mL spermatozoa concentration was subsequently su...
we have two part in this thesis, at first: the interaction of native calf thymus dna (ct-dna) with two anthraquinones including quinizarin (1,4- dihydroxy anthraquinone) and danthron (1,8- dihydroxy anthraquinone) in a mixture of 0.04 m brittone-robinson buffer and 50% of ethanol were studied at physiological ph by uv-vis absorption, florescence, circular dichroism spectroscopic methods, viscos...
OBJECTIVE To evaluate the effect of vaginal lubricants Pre-Seed, FemGlide, Astroglide, and Replens on human sperm motility and chromatin integrity. DESIGN Prospective, comparative, in vitro study. SETTING Andrology laboratory at tertiary care hospital. PATIENT(S) Thirteen normozoospermic donors. INTERVENTION(S) Semen samples from 13 subjects were incubated in human tubal fluid media (HT...
A person, who is talented, performs in a certain capacity above the norm. Talent is different from intelligence which is a response to a circumstance using knowledge and skill. The attributes of talent are exceptional memory, rapid processing speed, and high motivation, an affinity for learning, creativity and optimal cognition. There is some proof suggests that certain aspects of talent are re...
