introduction: to evaluate the quick cryopreservation technique on parameters of motility, morphology, and vitality of spermatozoa from normozoospermic ejaculates. materials and methods: in this prospective study, a total of 37 normal ejaculates were evaluated according to who criteria, then each sample was divided into two aliquets and sample was cryopreserved with quick freezing method. sperm ...

OBJECTIVES The effects of socioeconomic status (SES) on the incidence of well-differentiated thyroid cancer (WDTC) are well researched. However, the association between SES and outcomes is not delineated. Our objective was to determine if SES affected outcomes of WDTC. STUDY DESIGNS Retrospective database review. SETTING Tertiary care medical center. SUBJECTS AND METHODS The Henry Ford Vi...

Objectives: To re-examine interhospital variation in 30 day survival after acute myocardial infarction (AMI) 10 years on to see whether the appointment of new cardiologists and their involvement in emergency care has improved outcome after AMI. Design: Retrospective cohort study. Setting: Acute hospitals in Scotland. Participants: 61 484 patients with a first AMI over two time periods: 1988–199...

BACKGROUND Laparoscopic resection of colorectal cancer is widely used. However, robust evidence to conclude that laparoscopic surgery and open surgery have similar outcomes in rectal cancer is lacking. A trial was designed to compare 3-year rates of cancer recurrence in the pelvic or perineal area (locoregional recurrence) and survival after laparoscopic and open resection of rectal cancer. M...

t t The Australian weevil Oxyops vitiosa was released in 997 in Florida as a biological control agent of elaleuca quinquenervia. The larvae of this agent are ush-feeders, found only on the growing tips of their ost. Knowledge of this restriction to feeding on the rowing tips and other nutritional requirements may ssist in the establishment and dispersal of this speies. Therefore, O. vitiosa sur...

The micropropagation of Stevia rebaudiana using stem node segment explants obtained from 2 years-old shrubs were achieved. Cultures were established on Murashige and Skoog (MS) as the medium supplemented with different concentrations of 6-benzylaminopurine (BA) at concentration, 0.0, 0.1 and 0.5 mg/l individually or in combination with Kinetin (Kin) at concentration, 0.0, 0.1 and 0.5 mg/l. The ...

Oral supplementation with 50, 100 and 150 μg/ml arginine to the silkworm larvae resulted in a significant increase in the larval weight, silkgland weight in only 150 μg/ml, cocooning percentage in all the fed groups, female cocoon weight, cocoon shell weight, cocoon shell ratio, male cocoon weight, cocoon shell weight and shell ratio is increased in all the treated groups, filament length were ...

Nibea albiflora was immunized by intraperitoneal injection with either Lipopolysaccharide (LPS) or outer membrane protein (OMP) extracted from Vibrio vulnificus or formalin killed Vibrio vulnificus (FKC). The influence of the three antigens on the immunological function of Nibea albiflora was determined at different time points following the injection by testing the agglutinating antibody titer...

Cooling to -70 C killed a higher percentage of Acholeplasma laidlawii and Mycoplasma mycoides var. capri cells than cooling to -20 C. However, to preserve cell viability for prolonged periods storage at -70 C was much more preferable. The percentage of cells surviving freezing could be increased by increasing the initial cell concentration or by the addition of dimethyl sulfoxide or glycerol as...

sever coldness causes damage to the wheat and affect its growth and yield, thereby this experiment was conducted in controlled conditions to investigate freezing tolerance of 29 wheat genotypes. acclimation treatments (in two levels: acclimation and non-acclimation) were considered in the main plot and combination of temperature (0, -4, -8, -12, -16 ◦c) and genotypes as sub plot. survival perce...
