Genomic epidemiology analysis of drug-resistant Mycobacterium tuberculosis distributed in Mexico.

Genomics has significantly revolutionized pathogen surveillance, particularly in epidemiological studies, the detection of drug-resistant strains, and disease control. Despite its potential, the representation of Latin American countries in the genomic catalogues of Mycobacterium tuberculosis (Mtb), the bacteria responsible for Tuberculosis (TB), remains limited. In this study, we present a whole genome sequencing (WGS)-based analysis of 85 Mtb clinical strains from 17 Mexican states, providing insights into local adaptations and drug resistance signatures in the region.

Effect of biostimulation and bioaugmentation on biodegradation of high concentrations of 1,4-dioxane.

1,4-Dioxane is a pervasive and persistent contaminant in numerous aquifers. Although the median concentration in most contaminant plumes is in the microgram per liter range, a subset of sites have contamination in the milligram per liter range. Most prior studies that have examined 1,4-dioxane concentrations in the hundreds of milligrams per liter range have been performed with industrial wastewater.

Establishing the prevalence and relative rates of 1,4-dioxane biodegradation in groundwater to improve remedy evaluations.

Options for remediating 1,4-dioxane at groundwater sites are limited due to the physical-chemical properties of this compound. The relevance of natural attenuation processes for 1,4-dioxane was investigated through data from field, lab, and modeling efforts. The objectives were to use multiple lines of evidence for 1,4-dioxane biodegradation to understand the prevalence of this activity and evaluate convergence between lines of evidence.

The Relationship between Shoe Fitting and Foot Health of Persons with Down Syndrome: A Case Control Study.

: Down syndrome is the most common chromosomal abnormality and a cause of intellectual disability. It is also associated with orthopaedic and musculoskeletal problems of the locomotive apparatus, especially of the feet. These problems are believed to have a harmful effect on health, social functioning, and mobility.

Draft Genome Sequence of the 1,4-Dioxane-Degrading Bacterium Pseudonocardia dioxanivorans BERK-1.

strain BERK-1 grows aerobically with 1,4-dioxane as its sole substrate. Reported here is its draft genome sequence, with a size of 7.1 Mbp.

A counterfactual impact evaluation of a bilingual program on students' grade point average at a spanish university.

This observational study intends to estimate the causal effects of an English as a Medium of Instruction (EMI) program (as predictor) on students Grade Point Average (GPA) (as outcome) at a particular University in Spain by using a Counterfactual Impact Evaluation (CIE). The need to address the crucial question of causal inferences in EMI programs to produce credible evidences of successful interventions contrasts, however, with the absence of experimental or quasi-experimental research and evaluation designs in the field. CIE approach is emerging as a methodologically viable solution to bridge that gap.

[Cryptosporidium sp. infection in Cuban individuals infected by HIV].

A study was conducted on the presence of Cryptosporidium sp in 47 Cuban adult patients infected by HIV in different infective stages in order to assess for the first time its prevalence in this group. The parasite was found in 18 patients (38.3%), of whom 18 (44.

[Clinical, laparoscopic and histologic study of 60 patients with schistosomiasis mansoni].

Schistosomiasis mansoni was diagnosed to 60 patients coming from the African continent. Coproparasitologic study by Knight technique was performed to all of them, and presence of parasite eggs was demonstrated. The hematologic study showed eosinophilia and the study of the hepatic profile was normal.

[Visceral larva migrans].

The clinical records of patients with visceral larva migrans confirmed through laparoscopy and other tests are reviewed. This review was prompted by the admittance of two patients with this affection in the last years. Medical literature was reviewed, and conclusions are made.
