Preoperative and postoperative sperm parameter values from infertile men with varicocele were analyzed by computer-aided sperm analysis (CASA) to assess if sperm characteristics improved after varicocelectomy. Semen samples of men with proven fertility (n = 38) and men with varicocele-related infertility (n = 61) were also analyzed. Conventional semen analysis was performed according to WHO (20...
The National Science Foundation Engineering Research Center for Collaborative Adaptive Sensing of the Atmosphere (CASA) [McLaughlin et al., 2005] will be deploying the first generation of an automated network of four low-power, X-band, polarimetric, Doppler radars in Oklahoma in spring 2006. This radar network, known as NETRAD, will map precipitation and detect, locate and track severe weather ...
New observations of the vertically integrated CO2 mixing ratio, 〈CO2〉, from ground-based remote sensing show that variations in 〈CO2〉 are primarily determined by large-scale flux patterns. They therefore provide fundamentally different information than observations made within the boundary layer, which reflect the combined influence of large-scale and local fluxes. Observations of both 〈CO2〉 an...
The CASA (Carnegie-Ames-Stanford) ecosystem model based on satellite greenness observations has been used to estimate monthly carbon fluxes in terrestrial ecosystems from 2000 to 2009. The CASA model was driven by NASA Moderate Resolution Imaging Spectroradiometer (MODIS) vegetation cover properties and large-scale (1-km resolution) disturbance events detected in biweekly time series data. This...
We previously identified two inbred mouse strains, C57BL/6J and CASA/Rk, with different plasma plant sterol levels. An intercross between these strains revealed a broad plasma plant sterol locus on chromosome 14, which peaked at 17 centimorgan (cM) with a maximum logarithm of the odds score of 9.9. Studies in a chromosome 14 congenic strain, 14KK, with a 4-60 cM CASA/Rk interval on the C57BL/6J...
Sixty semen ejaculates from 10 mature bulls, 5 each of Jafarabadi and Mehsana breed, were studied for sperm motility and velocity parameters of fresh and frozen-thawed spermatozoa using computer assisted sperm analyzer (CASA). The mean values of motile and progressively motile spermatozoa observed in fresh semen of Jafarabadi and Mehsana bulls (79.77±1.62 and 61.80±1.85, and 78.90±1.22 and 61.3...
The main aims of this research were to study possible differences in objective morphometric sperm characteristics, establish normative sperm morphometry standards, and evaluate the presumed different subpopulation distribution of avian spermatozoa from the rooster (Gallus domesticus ) and Guinea fowl (Numida meleagris ) as model avian species. Seventy-two ejaculates (36 per species studied) wer...
Both genetic and environmental influences contribute to the wide variation in plasma von Willebrand factor (VWF) levels observed in humans. Inbred mouse strains also have highly variable plasma VWF levels, providing a convenient model in which to study genetic modifiers of VWF. Previously, we identified a major modifier of VWF levels in the mouse (Mvwf1) as a regulatory mutation in murine Galgt...
The conventional assessment of human semen, especially sperm movement characteristics, is a highly subjective assessment, with considerable intra- and inter-technician variability. Computer-assisted sperm analysis (CASA) systems provide a rapid and automated assessment of the parameters of sperm motion, together with improved standardization and quality control. However, it should be noted that...
این آزمایش جهت بررسی اثر خوراندن روغن ماهی به تنهایی و یا همراه با مکمل ویتامین e، بر منی تازه و یخ گشایی شده ی قوچ، انجام شد. شانزده قوچ سالم و بارور نژاد مهربان 3 تا 4 سال، در چهار گروه چهارتایی، با جیره شاهد (بدون روغن و ویتامین) و جیره های دارای روغن (30 گرم در روز برای هر قوچ)، دارای ویتامین e (200 واحد بین المللی در روز برای هرقوچ) و یا دارای روغن ماهی و ویتامین e به مدت 13 هفته، تغذیه شد...
