Mechanical, microstructural properties, mineral content and bone mineral density (BMD) of the femur were evaluated in growing rats fed with Opuntia ficus indica (L.) Mill. (Cactaceae) cladodes at different maturity stages as calcium source. Male weanling rats were fed with cladodes at early maturity stage (25 and 60 days of age, belonging to groups N-60 and N-200, respectively) and cladodes at late maturity stage (100 and 135 days of age, belonging to groups N-400 and N-600, respectively) for 6 weeks. Additionally, a control group fed with calcium carbonate as calcium source was included for comparative purposes...

Isela is an 11-year-old Mexican-American girl with mild intellectual disability. During a vacation with her family, she went swimming with dolphins. A few days later, Isela awoke at night with laughing spells; during the day, she was pacing, aggressive, and had a decline in self-care and communication skills. Her parents attributed the symptoms to the dolphins. She was evaluated by a pediatric neurologist. The sleep-deprived electroencephalogram, brain magnetic resonance imaging, lumbar puncture, and thyroid function tests were normal...

AIM: To determine the anatomical organization and somatic axonal components of the lumbosacral nerves in female rabbits. METHODS: Chinchilla adult anesthetized female rabbits were used. Anatomical, electrophysiological, and histological studies were performed. RESULTS: L7, S1, and some fibers from S2 and S3 form the lumbosacral trunk, which gives origin to the sciatic nerve and innervation to the gluteal region. From S2 to S3 originates the pudendal nerve, whose branches innervates the striated anal and urethra sphincters, as well as the bulbospongiosus, ischiocavernosus, and constrictor vulvae muscles...

The effect of blue maize extract in factors related to metabolic syndrome (MS) in Wistar rats was investigated. Total polyphenols, monomeric anthocyanins, and antioxidant activity were analyzed in blue maize. MS was induced in Wistar rats fed with high-sucrose (HS) diet for 12 weeks. During a period of 4 weeks, blue maize extract was administrated to HS groups fed with high-sucrose and high-cholesterol-high-sucrose (HS+C) diets. In the blue maize extract administered by orogastric cannulation, the levels of total polyphenols and anthocyanins were 9...

BACKGROUND: Associations between paraoxonase 1 (PON1) gene polymorphisms and heart diseases (HD) risk remain inconsistent. In order to obtain address this issue we performed a meta-analysis to assess the association between the L55M and Q192R polymorphisms of PON1 gene and heart diseases risk. METHODS: Relevant studies were enrolled by searching databases systematically. Odds ratios (ORs) with 95% confidence intervals (CIs) were used to calculate the strength of association...

This research studied the influence of the germ components on the physicochemical properties of cooked corn and nixtamalized corn flours as a function of the calcium hydroxide content (from 0 to 2.1 w/w) and steeping time (between 0 and 9h). A linear relationship was found between calcium content in germ and steeping time used during nixtamalization process. X-ray diffraction analysis showed that calcium carbonate is formed into the germ structure to 2.1 w/w of calcium hydroxide and 9h steeping time. The presence of the germ improves the development of peak viscosity in flours, and it is related to the increases in calcium concentration in germ and the formation of amylose-lipid complexes...

BACKGROUND: The association between the dopamine D2 receptor (DRD2) gene and schizophrenia has been studied though no conclusive outcomes have been attained. The aim of this study was to perform a systematic review and meta-analysis to explore the relation between three polymorphisms of the DRD2 gene (C957T, TaqI and Ser311Cys) and schizophrenia. METHODS: The search was made in PubMed and EBSCO databases (up to February 2016). The systematic review included 34 case-control association studies (34 for C957T, 16 for TaqI and 36 for Ser311Cys)...

BACKGROUND AND OBJECTIVE: Suicide is a worldwide health problem and climatological characteristics have been associated with suicide behavior. However, approaches such as the Knowledge Discovery in Database are not frequently used to search for an association between climatological characteristics and suicide. The aim of the present study was to assess the association between weather data and suicide in a Mexican population. METHODS: We used the information of 1357 patients who completed suicide from 2005 to 2012...

INTRODUCTION: Inflammation and endothelial dysfunction are considered the primary manifestations of the cardiovascular disease. Studies have established a relationship among components of metabolic syndrome (MetS) with inflammatory markers and the loss of permeability, vasoconstriction and vasodilatation endothelial. OBJECTIVE: To determine the relationship among the concentrations of soluble endothelial dysfunction molecules and inflammation cytokines and components of the metabolic syndrome in young population...

An overview of the combination of liquid-phase microextraction (LPME) techniques with graphite furnace atomic absorption spectrometry (GFAAS) is reported herein. The high sensitivity of GFAAS is significantly enhanced by its association with a variety of miniaturized solvent extraction approaches. LPME-GFAAS thus represents a powerful combination for determination of metals, metalloids and organometallic compounds at (ultra)trace level. Different LPME modes used with GFAAS are briefly described, and the experimental parameters that show an impact in those microextraction processes are discussed...

BACKGROUND: Thyroid cancer is the most common malignancy of the endocrine system, the papillary variant accounts for 80-90% of all diagnosed cases. In the development of papillary thyroid cancer, BRAF and RAS genes are mainly affected, resulting in a modification of the system of intracellular signaling proteins known as «protein kinase mitogen-activated» (MAPK) which consist of «modules» of internal signaling proteins (Receptor/Ras/Raf/MEK/ERK) from the cell membrane to the nucleus...

During the last decades, methods of halo conditioning have been developed to increase the tolerance to salinity in glucophyta crops. Some experiments have carried out the application of hydrogen peroxide (H2O2), in support to the modification of cell tolerance in saline medium. The first objective of this study was to evaluate the effects of the incorporation of H2O2 in salinity tolerance development of the aquatic lily (Eichhornia crassipes). Results showed that the incorporation of 0.03 % H2O2 salinity tolerance developed in salt concentrations similar to seawater...

Bismuth nanoparticles have many interesting properties to be applied in biomedical and medicinal sectors, however their safety in humans have not been comprehensively investigated. The objective of this research was to determine the cytotoxic effect of bismuth dimercaptopropanol nanoparticles (BisBAL NPs) on epithelial cells. The nanoparticles are composed of 18.7 nm crystallites on average and have a rhombohedral structure, agglomerating into chains-like or clusters of small nanoparticles. Based on MTT viability assay and fluorescence microscopy, cytotoxicity was not observed on monkey kidney cells after growing with 5 µM of BisBAL NPs for 24 h...

We thank the comments of Fernández-Niño [1] addressing our article [2] "Increase in Suicide Rates by Hanging in the Population of Tabasco, Mexico between 2003 and 2012", which pointed out that the use of the epidemiological concept "prevalence" is not correctly applied in the present manuscript.

BACKGROUND: Worldwide, the suicide rate is decreasing. To examine changes in the rates of completed suicide in the Mexican population from 2003 to 2012, we analyzed these changes according to: (i) the method of suicide; (ii) age group and (iii) gender. METHODS: The data analyzed were obtained from governmental organizations from the State of Tabasco, Mexico. The data provided 1836 cases of subjects born and residing in Tabasco, who completed suicide in this state...

The aim of the present study was to investigate the effect of C. papaya L. leaf extract (CPLE) on pancreatic islets in streptozotocin (STZ)-induced diabetic rats, as well as on cultured normal pancreatic cells with STZ in the medium. CPLE (3-125 mg/Kg) was administered orally for 20 days, while a group of diabetic rats received 5 IU/Kg/day of insulin. At the end of the treatment the rats were sacrificed. Blood was obtained to assess glucose and insulin levels. The pancreas was dissected to evaluate β cells by immunohistochemistry...
