BACKGROUND Vascular endothelial growth factor (VEGF) gene is an important angiogenesis regulator related to cancer development and progression. We evaluated the association between -2578 C/A (rs699947) VEGF polymorphism and PCa in Mexican subjects, to contribute to knowledge of VEGF role in genetic epidemiology of prostate cancer (PCa). OBJECTIVE The aim of this study was to evaluate the asso...

OBJECTIVES We explore the association between a neighbourhood's ethnic composition and the foods and nutrients consumed by Mexican-Americans. DESIGN Cross-sectional survey of a large national sample, from the Third National Health and Nutrition Examination Survey (1988-94), was linked to the 1990 Census. The outcomes were food frequencies and serum levels of micronutrients. The variable of in...

OBJECTIVES This research sought to describe the association between country of birth and gallbladder disease (GBD) in Mexican Americans, identify subgroups at especially high risk, and identify risk factors that may mediate a birthplace-GBD association. DESIGN Cross-sectional. METHODS Our study population included 4157 Mexican Americans aged 20-74 who participated in the 1988-94 third Natio...

Relatively few studies of hypertension have been carried out in Mexican-Americans, a population characterized by high rates of obesity and non-insulin-dependent diabetes mellitus. We therefore compared the prevalence of hypertension according to four different definitions in 3,297 Mexican-Americans and in 1,873 non-Hispanic whites from the San Antonio Heart Study, a population-based study of ca...

We, the U.S. Fish and Wildlife Service (Service), revise the regulations for the nonessential experimental population of the Mexican wolf (Canis lupus baileyi) under section 10(j) of the Endangered Species Act of 1973, as amended. This action is being taken in coordination with our final rule in this Federal Register to list the Mexican wolf as an endangered subspecies. The regulatory revisions...

OBJECTIVE To evaluate the use of β-blockers and to monitor heart rate in Mexican patients with coronary artery disease. METHODS CLARIFY is an outpatients registry with stable CAD. A total of 33,283 patients from 45 countries were enrolled between November 2009 and July 2010 from which 1342 were Mexican patients. RESULTS The mean HR pulse was 70 bpm (beats per minute). Patients in Mexico wer...

Understanding the spatial structure of a population is critical for effective assessment and management. However, direct observation of spatial dynamics is generally difficult, particularly for marine mammals. California sea lions (Zalophus californianus) are polygynous pinnipeds distributed along the Pacific coast of North America. The species' range has been subdivided into three management s...

Many countries, including Mexico, are facing a largely unrecognized epidemic of low-level lead poisoning. Mexico is the sixth largest lead-producing country in the world, and 40% of its production is used locally in different industrial processes that cause lead contamination of the environment. The major sources and pathways of lead exposure among the Mexican population are gasoline emissions,...
