Teratospermia (>60% of morphologically abnormal spermatozoa) is well documented in felids. Even morphologically normal spermatozoa from teratospermic ejaculates have reduced ability to undergo tyrosine phosphorylation, acrosome react, and bind and penetrate oocytes compared with normospermic (<40% abnormal spermatozoa) counterparts. However, it is unknown whether fertilization deficiencies orig...

run-out-table (rot) is located between last finishing stand and down coiler in a hot strip mill. as the hot steel strip passes from rot, water jets impact on it from top and bottom and strip temperature decreases approximately from 800-950 °c to 500-750°c. the temperature history that strip experience while passing through rot affects significantly the metallurgical and mechanical properties, s...

BACKGROUND Epidemiological studies of red meat consumption in relation to risk of heart failure (HF) are scarce. We examined the associations of unprocessed and processed red meat consumption with HF incidence and mortality in men. METHODS AND RESULTS The population-based prospective Cohort of Swedish Men included 37 035 men, aged 45 to 79 years, with no history of HF, ischemic heart disease,...
