system for the growth and asexual multiplication of cysticerci.

is the aetiological agent of cysticercosis, a zoonosis that causes severe health and economic losses across Latin America, Africa and Asia. The most serious manifestation of the disease is neurocysticercosis, which occurs when the larval stage (cysticercus) establishes in the central nervous system. Using as an experimental model organism for the study of cysticercosis, we aimed to identify the conditions necessary to allow parasite development at the short- and long terms.

Intermittent fasting may optimize intestinal microbiota, adipocyte status and metabolic health.

The aim of this review is to provide an overview of the present association between Intermittent Fasting (IF), the Gut Microbiota (GM), and the adipocyte with respect to Metabolic Health (MH). A search was carried out through Dialnet, Scielo, Web of Science, Redalyc and PubMed, using keywords such as: "intermittent fasting", "time-restricted feeding", "gut microbiota" and "Metabolic Health". Intermittent fasting (IF) regimens promote weight loss, therefore contributing to improved metabolic health.

Transcriptional effects of electroporation on Echinococcus multilocularis primary cell culture.

Echinococcus multilocularis is the etiological agent of alveolar echinococcosis (AE), a serious parasitic disease in the Northern Hemisphere. The E. multilocularis primary cell cultivation system, together with E.

Gene Participates in the Development of Primary Dyslipidemias.

Dyslipidemias are a group of diseases, which are characterized by abnormal blood concentrations of cholesterol, triglycerides and/or low-density lipoprotein-cholesterol (LDL-c). Dyslipidemia is a determinant condition for the progress of an atherosclerotic plaque formation. The resulting atherogenicity is due to at least two mechanisms: first, to the accumulation in the plasma of lipid particles that have the capacity to alter the function of the endothelium and deposit at the atheromatous plaque, and second, at an insufficient concentration of multifactorial type of high density lipoprotein-cholesterol (HDL-c), whose function is to protect against the development of atherosclerosis.

The spreading of Covid-19 in Mexico: A diffusional approach.

In this work, we analyze the spreading of Covid-19 in Mexico using the spatial SEIRD epidemiologic model. We use the information of the 32 regions (States) that conform the country, such as population density, verified infected cases, and deaths in each State. We extend the SEIRD compartmental epidemiologic with diffusion mechanisms in the exposed and susceptible populations.

Fatty Acids and Lipid Derivatives Protecting Photooxidative Attack in Age-related Macular Degeneration.

The objective is the systematic review of studies published in Scielo, Redalyc, Dialnet, Web of Science, Scopus and Pubmed, related to the inclusion of fatty acids and lipid derivatives in the daily diet to prevent or delay the appearance or progression of Age-Related Macular Degeneration (AMD). The analysis of the research results consulted shows that AMD is one of the most frequent causes of blindness in subjects over 55 years of age. AMD is characterized by decreased vision, metamorphopsia, macropsies, micropsies, and central scotoma.

Self-collected saliva for SARS-CoV-2 detection: A prospective study in the emergency room.

Current diagnostic standards involve severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) detection in nasopharyngeal swabs (NPS), but saliva is an attractive and noninvasive option for diagnosis. The objectives were to determine the performance of saliva in comparison with NPS for detecting SARS-CoV-2 and to compare the optimized home brew reverse-transcription polymerase chain reaction (RT-PCR) with a commercial RT-PCR. Paired NPS and saliva specimens were prospectively collected and tested by RT-PCR from patients presenting at an emergency room with signs and symptoms compatible with coronavirus disease-2019.

Stereotactic Radiotherapy for Hepatocellular Carcinoma, Radiosensitization Strategies and Radiation-Immunotherapy Combination.

Stereotactic body radiotherapy (SBRT) is an emerging ablative modality for hepatocellular carcinoma (HCC). Most patients with HCC have advanced disease at the time of diagnosis, and therefore, are not candidates for definitive-intent therapies such as resection or transplantation. For this reason, various alternative local and regional therapies have been used to prevent disease progression, palliate symptoms, and delay liver failure.

First identification and molecular phylogeny of from endangered felid () and other wild definitive hosts in one of the regions with highest worldwide biodiversity.
