Three iridoid glycosides (mussaenoside, geniposide, and 5-hydroxy-8-epi-deoxyloganin) along with mannitol and acteoside, were isolated from , an endemic plant species of Mexico that currently belongs to the Orobanchaceae family. There is no information about the chemical composition of this species, consequently, the present work focuses on the chemical study of the flowers and leaves of , which were collected in two batches in Mexico, identifying the main components of each batch. The chemical structures were completely established by spectroscopic methods.

Through multidisciplinary research, translational medicine allows a comprehensive approach to diseases in order to provide patients with adequate treatment, whose aim is personalized and precision medicine. In this context, the Cellular Immunology Laboratory of the Immunochemistry Research Unit, and the Dermatology Service of the 21st Century National Medical Center's Specialties Hospital (Hospital de Especialidades del Centro Médico Nacional Siglo XXI) have achieved a partnership that aspires to provide better quality patient care. This objective is achieved by evaluating the inflammatory skin infiltrates in different pathologies to observe changes in local immunity related to the response to treatment, and with the disease progression distinguish between dermatological diseases, highlight the importance of comprehensive skin care, and make decisions about treatment choice.

: Persistent Postural-Perceptual Dizziness (PPPD) is a frequent diagnosis in patients with chronic dizziness, ineffective postural control, visual dependence, and emotional symptoms. : 53 patients with PPPD (25-84 years old) and 53 adults (29-84 years old) with no vestibular disease agreed to participate in this study. Assessments included: vestibular function tests (sinusoidal yaw rotation and vestibular-evoked myogenic potentials); accuracy and precision of Subjective Visual Vertical (SVV) estimation while static and during on-axis yaw rotation; static posturography with open/closed eyes and 30° neck extension, while standing on hard/soft surface; questionnaires on symptoms of unsteadiness, spatial anxiety, dizziness-related handicap, anxiety/depression, depersonalization/derealization, and perceived stress.

The general features of the shift to a dormant state in mycobacterial species include several phenotypic changes, reduced metabolic activities, and increased resistance to host and environmental stress conditions. In this study, we aimed to provide novel insights into the viability state and morphological changes in dormant that contribute to its long-term survival under starvation or hypoxia. To this end, we conducted assays to evaluate cell viability, morphological changes and gene expression.

Objective: The aim of this study was to evaluate the experience of using endoscopic submucosal dissection (ESD), a technique considered as first-line of treatment, for the management of early neoplastic lesions (ENL), and subepithelial lesions (SEL) < 4 cms in size, in a tertiary-care, high-volume medical center in Mexico.
Method: Patients > 18 years-old, candidates to ESD with ENL and SMT, between January 2008 and October 2022 were included.
Results: ESD was performed in 246 patients (137 ENL and 109 SMT), 52.

Background: In Mexico, the detection of hepatitis B virus (HBV) in blood donors is achieved by screening for hepatitis B surface antigen (HBsAg). However there is still a residual risk of HBV transmission by blood components of donor suffering from occult HBV infection (OBI) or during the window period before seroconversion; in both the antigen expression can be undetectable.
Clinical Case: A 55 year old female donated whole blood in our blood bank,at health history and physical examination no health risk factors were detected.

Psoriasis is a chronic inflammatory autoimmune skin disease characterized by keratinocyte hyperproliferation, primarily driven by the IL-23/IL-17 axis. In addition to immune response, various skin components, including the epidermal barrier and the skin microbiota, have been individually implicated in the disease pathogenesis. Here, we aimed to investigate the interplay between epidermal tight junctions, Staphylococcus aureus enterotoxin B (SEB), and CD4 T cell-mediated immune responses.

With the increase in the number of people with advanced age (> 60 years) worldwide, it is necessary to understand the processes that lead to healthy aging. Cellular senescence, immunosenescence and inflammaging are part of the natural process of aging and are associated with age-related diseases. Cellular senescence is characterized by the arrest of the cell cycle in the G1 phase.
