This study examined factors that predicted children's gender intergroup attitudes at age 5 and the implications of these attitudes for intergroup behavior. Ethnically diverse children from low-income backgrounds (N = 246; Mexican-, Chinese-, Dominican-, and African American) were assessed at ages 4 and 5. On average, children reported positive same-gender and negative other-gender attitudes. Positive same-gender attitudes were associated with knowledge of gender stereotypes. In contrast, positive other-gender attitudes were associated with flexibility in gender cognitions (stereotype flexibility, gender consistency)...

There is scarce information about the link between specific single-nucleotide polymorphisms (SNPs) and risk of liver disease among Latinos, despite the disproportionate burden of disease among this population. Our aim was to investigate nine SNPs in or near the following genes: PNPLA3, LYPLAL1, PPP1R3B, GCKR, NCAN, IRS1, PPARG, and ADIPOR2 and examine their association with persistently elevated alanine aminotransferase (ALT) or aspartate aminotransferase (AST) levels in Mexican adults. Data and samples were collected from 741 participants in the Mexican Health Worker Cohort Study, in Cuernavaca, Mexico...

Cystic fibrosis (CF) is the most common autosomal recessive disease in the Caucasian population, but it has also been widely diagnosed in the Mexican population. Production of viscous secretions affects the secretory epithelia and the respiratory condition usually leads to death. The relationship between the CFTR genotype and the disease phenotype is not well understood. Other risk factors such as genetic and autoimmune influence the development of this disease. We analyzed the PTPN22 R620W polymorphism (+1858 C/T, rs2476601) in 78 DNA samples from CF patients and 232 healthy controls from northeast Mexico using the polymerase chain reaction-restriction fragment length (PCR-RFLP) method...

BACKGROUND AND AIMS: Oxidative disturbance is an important factor involved in the etiology of comorbidities associated with obesity. Genetic polymorphisms such as SOD1 -251A>G, SOD2 47 C>T, CAT -21A>T and CAT -262 C>T have been described to alter the activity of antioxidant enzymes. The aim of the present work was to analyze the association of the mentioned SNPs with obesity and their relationship with anthropometric and clinical variables in this group. METHODS: The study included 416 Mexican women (208 normal weight, NW and 208 subjects with obesity, OB)...

This study examined perceptions of family care, nursing homes, and expectations of future care among 85 Mexican-origin women caregivers, some who lived in Mexico City and some who lived in East Los Angeles, California (East LA). Attitudes of Mexican-born women-living in Mexico City and in East LA-were more similar to each other than those of U.S.-born women. Most caregivers reported a preference for family care and had negative views of institutional care. In addition, despite the negative views about nursing homes, some caregivers expressed a willingness to seek nursing-home care for themselves so as to avoid burdening their children in the future...

The goals of this study were 1) to test the relative contribution of light-intensity and moderate-to-vigorous intensity physical activity (MVPA) to Cardiovascular Disease (CVD) risk in older adults, and 2) to examine the influence of ethnicity. We used pooled data from the 2003-2004 and 2005-2006 waves of the National Health and Nutritional Examination Survey (NHANES). The sample consisted of 1,171 White, Black and Mexican American adults aged 65 and older. Using ordinary least squares regression, we showed no statistically significant relationship between lower CVD risk with light intensity activity...

Perhaps the most important recent advance in species delimitation has been the development of model-based approaches to objectively diagnose species diversity from genetic data. Additionally, the growing accessibility of next-generation sequence datasets provides powerful insights into genome-wide patterns of divergence during speciation. However, applying complex models to large datasets is time consuming and computationally costly, requiring careful consideration of the influence of both individual and population sampling, as well as the number and informativeness of loci on species delimitation conclusions...

Head movements are typically viewed as a nuisance to functional magnetic resonance imaging (fMRI) analysis, and are particularly problematic for resting state fMRI. However, there is growing evidence that head motion is a behavioral trait with neural and genetic underpinnings. Using data from a large randomly ascertained extended pedigree sample of Mexican Americans (n = 689), we modeled the genetic structure of head motion during resting state fMRI and its relation to 48 other demographic and behavioral phenotypes...

The antimicrobial peptide PaDef was isolated from Mexican avocado fruit and was reported to inhibit the growth of Escherichia coli and Staphylococcus aureus in 2013. In this study, an N-terminal 6 × His tagged recombinant PaDef (rPaDef) with a molecular weight of 7.5 KDa, for the first time, was expressed as a secreted peptide in Pichia pastoris. The optimal culture condition for rPaDef expression was determined to be incubation with 1.5% methanol for 72 h at 28 °C under pH 6.0. Under this condition, the amount of the rPaDef accumulation reached as high as 79...

Gendered interpersonal processes may explain the elevated rates of internalizing symptoms among adolescent girls relative to boys. Two such processes are peer social rejection and social support. The current study assessed for gender differences in the effect of 7th grade peer social rejection on 10th grade internalizing symptoms, as well as the moderating effects of social support from family and from friends in a sample of 749 (49 % female) Mexican American adolescents, an understudied population with a unique social culture...

Dating violence is a significant problem in Mexico. National survey data estimated 76 % of Mexican youth have been victims of psychological aggression in their relationships; 15.5 % have experienced physical violence; and 16.5 % of women have been the victims of sexual violence. Female adolescents perpetrate physical violence more frequently than males, while perpetration between genders of other types of violence is unclear. Furthermore, poor, marginalized youth are at a higher risk for experiencing dating violence...

Objective. To evaluate the association of -174G/C IL-6 polymorphism with failure in therapeutic response to methotrexate (MTX) or leflunomide (LEF). This prospective, observational cohort included 96 Mexican-Mestizo patients with moderate or severe rheumatoid arthritis (RA), initiating MTX or LEF, genotyped for IL-6 -174G/C polymorphism by PCR-RFLP. Therapeutic response was strictly defined: only if patients achieved remission or low disease activity (DAS-28 < 3.2). Results. Patients with MTX or LEF had significant decrement in DAS-28 (p < 0...

Research by economists suggests that recent Mexican migrants are better educated and have higher socioeconomic status (SES) than previous migrants. Because factors associated with higher SES and improved education can lead to positive secular changes in overall body form, secular changes in the craniofacial complex were analyzed within a recent migrant group from Mexico. The Mexican group represents individuals in the act of migration, not yet influenced by the American environment, and thus can serve as a starting point for future studies of secular change in this population group...

This article resurrects the puppet show Las calenturas de Don Ferruco (Don Ferruco's Fevers), which was televised in the late 1950s in order to help eradicate malaria in Mexico, as a useful instrument for health education. It analyzes how the spread of educational puppet shows on Mexican television showed the need to keep updating preventive healthcare pedagogy and it underlines the importance of television as an educational health-promotion production in the mid-twentieth century. The article discusses the early use of puppet shows as an especially important tool for what would later become mass-media transmission of discourses from the Secretaría de Salubridad y Asistencia (Department of Health and Healthcare)...

We studied species diversity and genetic variation among populations of Brevipalpus mites from four species of citrus host plants. We sampled mites on orange, lime, grapefruit and mandarin trees from orchards at six localities distributed in the five most important citrus producing states in Mexico. Genetic variation among citrus host plants and localities were assessed by analysis of nucleotide sequence data from fragments of the mitochondrial cytochrome oxidase subunit I (COI). Both Brevipalpus yothersi and B...
