This study was undertaken to compare the efficiency of fresh and frozen-thawed buck semen on in vitro fertilization (IVF) of goat oocytes. Cumulus oocytes complexes (COCs) were collected by aspiration of 2-6 mm diameter follicles, which were obtained from slaughterhouse. Upon grading, only normal quality COCs were maturated in TCM-199 for 48 hours. The percentage of COCs reached to the M-II sta...

Methods. Two lumbar punctures were performed for clinical diagnostic purposes. Spun leukocytes in CSF and blood were stained promptly with a panel of directly conjugated monoclonal antibodies to identify lymphocyte subsets. Data were acquired and analyzed on a 5-color single laser Becton-Coulter Cytomics FC500 flow cytometer (St. John's Hospital, Springfield, IL). Also, CSF, serum, and blood sa...

A bstra ct . When one compares t he time evolution of two spin configura tions subjected to the same t hermal noise, domains appea r of ident ical and opposite spins . We st udy these domains and their growt h for three magnetic systems in two dime nsions: ferromagnet, spin glass, and non-symmetric spin glass. For Ierromagnet s, t hese distan ce associated domains are very similar to the magnet...

This study examined the effects of long-term frozen storage (-20 °C for 5 months) of free amino acids (FAAs) and nucleotide-related compounds (NRCs) in muscle and hepatopancreas of the coconut crab Birgus latro. Although long-term frozen storage had little effect on FAA composition in muscle, the amounts of several FAAs increased in the hepatopancreas that may be the result of protein decom...

D e s c r i p t i o n o f t e s t s a n d d i a g n o s t i c s t a n d a r d Blood for BNP levels was taken using the Triage BNP test (Biosite Diagnostics, San Diego, CA, USA), a point-of-care method based on fluorescence immunoassay. The BNP measurements were done on frozen plasma approximately 1 to 2 months after blood collection. Doppler echocardiography was done within 60 minutes of enroll...

The polycyclic aromatic hydrocarbon (PAH) coronene (C24H12) frozen in D2O ice in a ratio of less than 1 part in 500 rapidly exchanges its hydrogen atoms with the deuterium in the ice at interstellar temperatures and pressures when exposed to ultraviolet radiation. Exchange occurs via three different chemical processes: D atom addition, D atom exchange at oxidized edge sites, and D atom exchange...

Faces of lesion nematodes Pratylenchus teres (populations RTB and JK) and P. zeae or the bacterivore Distolabrellus veechi were observed on frozen specimens with low-temperature scanning electron microscopy and as chemically fixed, critical-point dried specimens with conventional scanning electron microscopy. Amphidial secretions were preserved in chemically fixed but not cryofixed lesion nemat...
