Abstract
The parasite Trichomonas vaginalis is the etiologic agent of trichomoniasis, the most common non-viral sexually transmitted disease worldwide. This infection often remains asymptomatic and is related to several health complications. The traditional treatment for trichomoniasis is the use of drugs of the 5-nitroimidazole family, such as metronidazole; however, scientific reports indicate an increasing number of drug-resistant strains. Benzimidazole derivatives could offer an alternative in the search for new anti-trichomonas drugs. In this sense, two attractive candidates are the compounds O2N-BZM7 and O2N-BZM9 (1H-benzimidazole derivatives), since, through in vitro tests, they have shown a higher trichomonacide activity. In this study, we determined the effect on the expression level of metabolic genes in T. vaginalis. The results show that genes involved in redox balance (NADHOX, G6PD::6PGL) are overexpressed, as well as the gene that participates in the first reaction of glycolysis (CK); on the other hand, structural genes such as ACT and TUB are decreased in expression in trophozoites treated with the compound O2N-BZM9, which would probably affect its morphology, motility and virulence. These results align with the trichomonacidal activity of the compounds, with benzimidazole O2N-BZM9 being the most potent, with an IC50 value of 4.8 μM. These results are promising for potential future therapeutic applications.

Abstract
Glucose-6-phosphate dehydrogenase (G6PD) deficiency, affecting an estimated 500 million people worldwide, is a genetic disorder that causes human enzymopathies. Biochemical and genetic studies have identified several variants that produce different ranges of phenotypes; thus, depending on its severity, this enzymopathy is classified from the mildest (Class IV) to the most severe (Class I). Therefore, understanding the correlation between the mutation sites of G6PD and the resulting phenotype greatly enhances the current knowledge of enzymopathies' phenotypic and genotypic heterogeneity, which will assist both clinical diagnoses and personalized treatments for patients with G6PD deficiency. In this review, we analyzed and compared the structural and functional data from 21 characterized G6PD variants found in the Mexican population that we previously characterized. In order to contribute to the knowledge regarding the function and structure of the variants associated with G6PD deficiency, this review aimed to determine the molecular basis of G6PD and identify how these mutations could impact the structure, stability, and function of the enzyme and its relation with the clinical manifestations of this disease.

Abstract
Treatments to combat giardiasis have been reported to have several drawbacks, partly due to the drug resistance and toxicity of current antiparasitic agents. These constraints have prompted many researchers to investigate new drugs that act against protozoan parasites. Enzyme inhibition is an important means of regulating pathogen metabolism and has recently been identified as a significant alternative target in the search for new treatments. Glucose-6-phosphate dehydrogenase and 6-phosphogluconolactonase (G6PD::6PGL) is a bifunctional enzyme involved in the pentose phosphate pathway (PPP) in Giardia lamblia (G. lamblia). The G. lamblia enzyme is unusual since, unlike the human enzyme, it is a fused enzyme. Here, we show, through inhibition assays, that an in-house chemical library of 120 compounds and four target compounds, named CNZ-7, CNZ-8, CMC-1, and FLP-2, are potent inhibitors of the G. lamblia G6PD::6PGL fused enzyme. With a constant (k2) of 2.3, 3.2, and 2.8 M−1 s−1, respectively, they provoke alterations in the secondary and tertiary protein structure and global stability. As a novel approach, target compounds show antigiardial activity, with IC50 values of 8.7, 15.2, 15.3, and 24.1 µM in trophozoites from G. lamblia. Moreover, these compounds show selectivity against G. lamblia, since, through counter-screening in Caco-2 and HT29 human cells, they were found to have low toxicity. This finding positions these compounds as a potential and attractive starting point for new antigiardial drugs.

Abstract
Helicobacter pylori (H. pylori) has been proposed as the foremost risk factor for the development of gastric cancer. We found that H. pylori express the enzyme glucose-6-phosphate dehydrogenase (HpG6PD), which participates in glucose metabolism via the pentose phosphate pathway. Thus, we hypothesized that if the biochemical and physicochemical characteristics of HpG6PD contrast with the host G6PD (human G6PD, HsG6PD), HpG6PD becomes a potential target for novel drugs against H. pylori. In this work, we characterized the biochemical properties of the HpG6PD from the H.pylori strain 29CaP and expressed the active recombinant protein, to analyze its steady-state kinetics, thermostability, and biophysical aspects. In addition, we analyzed the HpG6PD in silico structural properties to compare them with those of the HsG6PD. The optimal pH for enzyme activity was 7.5, with a T1/2 of 46.6 °C, at an optimum stability temperature of 37 °C. The apparent Km values calculated for G6P and NADP+ were 75.0 and 12.8 µM, respectively. G6P does not protect HpG6PD from trypsin digestion, but NADP+ does protect the enzyme from trypsin and guanidine hydrochloride (Gdn-HCl). The biochemical characterization of HpG6PD contributes to knowledge regarding H. pylori metabolism and opens up the possibility of using this enzyme as a potential target for specific and efficient treatment against this pathogen; structural alignment indicates that the three-dimensional (3D) homodimer model of the G6PD protein from H. pylori is different from the 3D G6PD of Homo sapiens.

Abstract
INTRODUCTION AND AIM Gastic cancer is the most frequent neoplasia of the digestive tract worldwide. Incidence rates vary according to the region or country analyzed. Variation in the different regions of Mexico is attributed to very specific dietary, environmental, and genetic patterns. The aim of the present work was to carry out an epidemiologic analysis of the cases of gastric cancer treated at the Hospital Regional de Alta Especialidad 'Ciudad Salud', located in Chiapas, Mexico. MATERIAL AND METHODS A descriptive, ambispective, longitudinal study was conducted. Cases of gastric cancer were searched for in the database from the oncology service of our hospital, that were treated within the time frame of 2007 to 2014. The data obtained were analyzed using the SPSS v. 20 statistics program. RESULTS A total of 100 cases of gastric cancer were detected, 84 of which were included in the study. Forty-one of the cases were men, 43 were women, and their mean age was 57.3 years. Incidence was 2.14 for every 100 oncology patients released from the hospital. Of the study patients, 35.71% stated they had been alcoholics, 22.61% were smokers, and 90.16% were diagnosed with adenocarcinoma. At the end of follow-up, 18 of the study patients had died. CONCLUSION The results of the present epidemiologic analysis showed that the consumption of alcohol and tobacco played an important role in the development of gastric cancer in the patients studied, as well as having a family history of any type of cancer. Because gastric cancer is usually diagnosed in advanced stages, it would be reasonable to formulate a strategy for the prevention, early detection, and control of the disease in the State of Chiapas, Mexico.

Abstract
Background The emerging chikungunya virus (CHIKV), is an arbovirus causing intense outbreaks in North America. The situation in Mexico is alarming, and CHIKV threatens to spread further throughout North America. Clinical and biological features of CHIKF outbreaks in Mexico have not been well described; thus, we conducted a cross sectional study of a CHIKV outbreak in Chiapas, Southern Mexico to further characterize these features. Methodology/Principal findings We collected blood samples from patients suspected of having chikungunya fever (CHIKF) who presented to Clinical Hospital ISSSTE Dr. Roberto Nettel in Tapachula, Chiapas, Mexico. In addition to the clinical examination, real-time polymerase chain reaction (PCR) standardized for the Asian Chikungunya lineage and/or enzyme-linked immunosorbent assay for immunoglobulin M (IgM) were used to confirm CHIKV diagnosis. Of a total of 850 patients who presented with probably CHIKV at Hospital “Dr. Roberto Nettel”, 112 probable CHIKF cases were enrolled in this study from November 2014- June 2015, of which 95 patients (84.8%) were CHIKV positive and 17 were negative (15.2%). Of these 95 CHIKV positive patients, 62 were positive by real-time reverse transcriptase PCR (+qRT-PCR); and 33 were seropositive to +IgM with a negative qRT-PCR. The most frequent symptoms reported were fever (100%), headache (82.3%), polyarthralgia (72.1%), and exanthem (82.3%). Biological abnormalities observed during CHIKV infection were lymphopenia (41.1%), leukopenia (51.6%), elevated transaminases (30.5%-46.3%) and high LDH (46.3%) and CRP (60.0%). Conclusion Clinical and biological data obtained from this study is providing more useful information for benchmarking purposes with outbreaks from different parts of the world and would be helpful for better patient care and treatment.

OBJECTIVE To determine the Trypanosoma cruzi infection prevalence in 1125 pregnant women and the transmission frequency to their children from Tapachula and Palenque, Chiapas. MATERIALS AND METHODS We determined the prevalence by serology tests and the transmission frequency by polymerase chain reaction (PCR) and T. cruzi reactivity capacity after 12 months. RESULTS Total maternal infection prevalence were 23/1 125 (2.04%), 9/600 (1.5%) were from Tapachula and 14/525 (2.6%) from Palenque. The seropositive women were between 20 and 35 years old, 31.8% have Premature Rapture of Membrane and 9.1% have history of perinatal death. The total percentage of positive newborns by PCR was 9/23 (39.13%), out of those 2/9 (22.2%) are from Tapachula and 7/14 (50%) from Palenque. The Maternal Fetal transmission frequency was. 2/9 (22.2%) in Tapachula and 1/14 (7.14%) in Palenque, all positive infants were asynthomatic. CONCLUSION The maternal-fetal transmission rate in Chiapas State is variable; the reason could be the maternal immunological status and T. cruzi strain.

Abstract
INTRODUCTION The genes coding for proteins due to their activity in several metabolic pathways could be related with the onset of acute coronary syndromes. OBJECTIVE Relationship among polymorphisms and adverse events in. METHODS Prospective. In--hospital, one--year follow-up. Inclusion Acute coronary syndromes with ST elevation or depression secondary to atherothrombosis, clinical stability. In all, polymerase chain reaction and length polymorphism of restriction fragments. By standardizing chain reactions and genotyping,a preliminary analysis of distribution of genotypes was performed for each polymorphism and no deviations were observed in the law of Hardy-Weinberg equilibrium (P>.05). RESULTS From 2003 to 2005, 150 subjects were enrolled. We analyzed 14 polymorphisms in 9 genes (fibrinogen, factor v, vii, ii, xiii, plasminogen activator and inhibitor-1, C-reactive protein). In acute coronary syndromes, fibrinogen>450 mg/dL and white blood count 8500 cells/mm(3) were markers of poor prognosis to one year. Regression analysis identified the -148 CT/TT and fibrinogen -717 AG/GG of C-reactive protein as a marker of recurrent ischemia and reinfarction 1691GA + AA. CONCLUSION We are showing a relationship among polymorphisms involved in inflammation and hemostasis with adverse events in the acute phase and follow-up in acute coronary syndromes patients that could be considered as markers of ischemic heart disease. Larger sample is needed to confirm these results.
