Paternal lineages and forensic parameters based on 23 Y-STRs (Powerplex® Y23) in Mestizo males from Mexico City.

We analyzed 307 Mexican-Mestizo (admixed) males from Mexico City with the Powerplex® Y23 system. The complete list of Y-STR haplotypes was uploaded into the YHRD database (accession number YA004275). The discriminatory capacity (98.

Muscarinic Receptors Types 1 and 2 in the Preoptic-Anterior Hypothalamic Areas Regulate Ovulation Unequally in the Rat Oestrous Cycle.

Muscarinic receptors types 1 (mAChR) and 2 (mAChR) in the preoptic and anterior hypothalamus areas (POA-AHA) were counted, and the effects of blocking these receptors on spontaneous ovulation were analysed throughout the rat oestrous cycle. Rats in each phase of the oestrous cycle were assigned to the following experiments: (1) an immunohistochemical study of the number of cells expressing mAChR or mAChR in the POA-AHA and (2) analysis of the effects of the unilateral blockade of the mAChR (pirenzepine, PZP) or mAChR (methoctramine, MTC) on either side of the POA-AHA on the ovulation rate. The number of mAChR-immunoreactive cells was significantly higher at 09:00 h on each day of the oestrous cycle in the POA-AHA region, while no changes in the expression profile of mAChR protein were observed.
