The blood samples were collected from 37 TNBC diagnosed patients and 34 age-matched non-TNBC controls to investigate the expression of miRNA panel. Plasma was isolated by standard protocol of centrifugation and then isolation of total RNA including miRNA was done. About 100ng o...

The average length of the estrous cycle in Lohi sheep was 17.0±0.1 days and follicular and luteal phases were 4.6±0.2 and 11.3±0.2 days long, respectively. Estrous cycles had either three or four follicular waves; 3-wave cycles were more frequent than 4-waves (87vs.13%; p≤0.05, respectively). In...
