BACKGROUND The mechanisms underlying chronic obstructive pulmonary disease (COPD) remain unclear. MicroRNAs (miRNAs or miRs) are small non-coding RNA molecules that modulate the levels of specific genes and proteins. Identifying expression patterns of miRNAs in COPD may enhance our understanding of the mechanisms of disease. A study was undertaken to(More)
The acrosome reaction (AR) is influenced by the action of several molecules such as GABA, P 4 , and E 2. Objective: to determine the interaction between GABA / E 2 , and GABA / P 4 in the AR. Methods: Washed human spermatozoa capacitated for 2 h were incubated in the following conditions: BWW medium alone (control) or BWW plus: P 4, E 2, GABA, GABA+ P 4 or(More)
