Milk intake and IGF-1 rs6214 polymorphism as protective factors to obesity.

Mexico ranks 2 in adult obesity and 4 in milk intake worldwide. Low levels of IGF-1 have been related to obesity and can be reverted by milk intake. The rs6214 polymorphism has been associated with an increase in the expression of IGF-1.

Prevalence, antimicrobial resistance and virulence genes of Escherichia coli isolated from retail meat in Tamaulipas, Mexico.

Objectives: The aim of this study was to determinate the prevalence of Escherichia coli and its resistance to antimicrobials and the presence of virulence genes in retail samples of beef and pork in several locations in Tamaulipas, Mexico.

Methods: A total of 106 samples (54 beef and 52 pork) collected from August 2013 to March 2014 were analysed to detect E. coli isolates.

Alopecia Areata. Current situation and perspectives.

Alopecia areata (AA) is a dermatological disease characterized by non-scarring hair loss of the scalp and/or body, with an unpredictable and variable evolution in the patients in which, despite multidisciplinary efforts, its etiology is not entirely known, although some evidence suggests that environmental, immunological and genetic factors could be generating the disease. The aim of this review is to provide an updated panorama of the clinical characteristics, diagnosis and treatment of AA, to analyze the mechanisms that could participate in its etiology, as well as to review some of the most important genetic variants that could confer susceptibility to the development of this disease.

Bacterial Prevalence and Antibiotic Resistance in Clinical Isolates of Diabetic Foot Ulcers in the Northeast of Tamaulipas, Mexico.

Diabetic foot ulcers (DFUs) are a serious and common problem in patients with diabetes mellitus and constitute one of the major causes of lower extremity amputation. The microbiological profile of DFUs depends on the acute or chronic character of the wound. Aerobic gram-positive cocci are the predominant organisms isolated from DFUs.

[From genetics to genomics in the rational design of new Mycobacterium tuberculosis vaccines].

Tuberculosis (TB) is an infectious disease affecting people from all ages all over the world. It is estimated that one third of the world population lives infected with the causal agent: Mycobacterium tuberculosis. Despite availability and systematic administration of BCG vaccine in endemic areas, TB transmission remains elusive to control, partly because BGC efficacy has been shown to have wide variability (0-80%).

Thyroid hormones according to gestational age in pregnant Spanish women.

Background: Thyroid function changes during pregnancy and maternal thyroid dysfunction have been associated with adverse outcomes. Our aim was to evaluate thyroid hormones levels in pregnant women resident in Aragon, Spain.

Findings: Samples for 1198 pregnant women with no apparent thyroid disorders were analyzed, using paramagnetic microparticle and chemiluminescent detection technologies, in order to determine levels of thyroid stimulating hormone (TSH), free triiodothyronine (FT3), free thyroxine (FT4), thyroid peroxidase antibodies (TPO-Ab), and thyroglobulin antibodies (Tg-Ab).
