Abstract: Allele frequency distributions for 15 STR loci (AmpFlSTR Identifiler kit) were estimated in 825 volunteers of the following eight Mexican-Amerindian populations from two geographical regions: (1) North: Tarahumara (204), Mayo (45), Seri (28), and Guarij o (17); (2) Northwest: Tepehuano (123), Mexicanero (84), Cora (85), and Huichol (239). Genotype frequency distribution was in agreement with Hardy-Weinberg expectations for all 15 STRs, excepting for two loci (D13S317 and FGA) in the Huichol population. The power of discrimination and power of exclusion values were both larger than 0.99999. These STR databases will support the correct interpreting of DNA profiles in paternity testing and forensic cases in Mexican-Amerindian groups from these regions, until know poorly studied. Genetic distances and pairwise comparisons were estimated between populations. A significant genetic differentiation was observed between these Mexican-Amerindian groups (FST = 3.43%; p = 0.0000) that was 10 times larger than the observed between Mestizos (F ST = 0.34%), which represent most of the Mexican population (?90%). This result was in agreement with the incapability to cluster these Native American populations by geographic criteria. Pre-Colombian descriptions of Aridoamerica, including the North region of Mexico, suggest genetic drift effects to explain this noticeable population differentiation of Mexican-Amerindian groups.

The present study examines the performance of school-aged boys and girls from two age groups on several mathematical tasks and analyzes the predictive value of a verbal fluency test and a spatial test on those mathematical tasks. More specifically, our research attempts to answer the following two questions: (1) Are gender differences in mathematical test performance among children interrelated with age and (2) do verbal and spatial nonmathematical tests mediate gender effects on mathematical test performance? Two hundred and seventy-eight 7- to 10-year-old children and 248 13- to 16-year-olds were selected from schools in Colombia and Mexico (231 boys and 295 girls). The age effect was found to be significant for all measures, with scores improving with age. Results showed that boys and girls in both age groups scored similarly in most subtests, but that differences emerged in the performance of mental mathematical operations and in resolving arithmetical problems. In the latter - but not in mental math - older boys outperformed older girls, whereas no gender differences were observed in the younger groups. After controlling for age, it was found that the spatial test was, indeed, a significant mediator of gender effects, while the verbal task was not.",,,,,,"10.1080/09297040802195205",,,"http://hdl.handle.net/20.500.12104/41662","http://www.scopus.com/inward/record.url?eid=2-s2.0-67649690473&partnerID=40&md5=628ccdba077a9c80376887654c4ed7e9",,,,,,"3",,"Child Neuropsychology",,"216

Following U.S. Department of Agriculture Food Safety and Inspection Service protocols, Salmonella was isolated from 78 (15.4%) beef carcasses (n = 505) after the final carcass water wash. Isolation frequency differed by establishment (P < 0.05) and was higher (P < 0.05) during the wet season (May through September) for all establishments. Thirteen Salmonella serotypes and four serogroups (partially serotyped isolates) were identified. The most prevalent were Salmonella enterica Give (24.4%), Salmonella Typhimurium (17.9%), and Salmonella Group B (14.1%). Antimicrobial susceptibility was tested against 11 drugs, and results indicated that 46.2% of the isolates were resistant to tetracycline, 42.3% were resistant to streptomycin, 23.1% were resistant to chloramphenicol, 21.8% were resistant to trimethoprim- sulfamethoxazole, and 19.2% were resistant to gentamicin. No resistance to ceftriaxone or ciprofloxacin was observed, and 33% of the isolates were resistant to three or more antimicrobials. Although Salmonella Give was the most prevalent serotype, 95% of the isolates of this serotype were susceptible to all antimicrobials tested. Antimicrobial resistance was more common in Salmonella Typhimurium, and 93% (13 of 14) of the isolates of this serotype were resistant to at least five antimicrobials. The frequency of multidrug-resistant Salmonella isolates differed among establishments (P < 0.05) and may be related to the origin of the cattle presented for harvesting. These findings highlight the need for control measures to reduce Salmonella prevalence on beef carcasses in small abattoirs in Mexico and for strategies to ensure the cautious use of antimicrobials in animal production to prevent and control the spread of antimicrobial-resistant foodborne pathogens.
