Epstein-Barr Virus Infection Presenting With Acute Gastrointestinal Involvement. Report of Two Cases of Epstein-Barr Virus Colitis in Kidney-Transplant Recipients and Scoping Review of the Literature.

Epstein-Barr virus (EBV) is a herpesvirus capable of establishing lifelong latent infections, leading to a wide spectrum of diseases. It can affect multiple organs, including the gastrointestinal tract, typically through lymphoproliferative syndromes or gastric cancer, while acute gastrointestinal disease is rare and poorly understood. Two cases of EBV-induced acute colitis in kidney transplant recipients were described.

Hypothalamic Regulation of Cardiorespiratory Functions: Insights into the Dorsomedial and Perifornical Pathways.

The plays a pivotal role in the orchestration of sympathetic nervous system activities. Through its projections to the brainstem and pontomedullary nuclei, it controls heart rate, contractility, blood pressure, and respiratory activity, such as timing and volumes. The DMH integrates inputs from higher brain centers and processes these signals in order to modulate autonomic outflow accordingly.

Telomeres: an organized string linking plants and mammals.

Telomeres are pivotal determinants of cell stemness, organismal aging, and lifespan. Herein, we examined similarities in telomeres of Arabidopsis thaliana, mice, and humans. We report the common traits, which include their composition in multimers of TTAGGG sequences and their protection by specialized proteins.

Unravelling the diversity of Dubois, 1936 (Trematoda: Diplostomidae) in fish-eating birds from the Neotropical region of Mexico, with the description of a new species.

Adults of the genus , Dubois, 1936 are parasites of fish-eating birds, mainly of the family Ardeidae, and are globally distributed. The genus currently comprises 35 species, although recent molecular evidence has shown that the diversity of the genus is underestimated since several candidate species have been recognized. In the Neotropical region of Mexico, at least 6 lineages have been detected with metacercaria stages recovered from unrelated fish hosts.

Cm-p5, a molluscan-derived antifungal peptide exerts its activity by a membrane surface covering in a non-penetrating mode.

Amidst the health crisis caused by the rise of multi-resistant pathogenic microorganisms, Antimicrobial Peptides (AMPs) have emerged as a potential alternative to traditional antibiotics. In this sense, Cm-p5 is an AMP with fungistatic activity against the yeast Candida albicans. Its antimicrobial activity and selectivity have been well characterized; however, the mechanism of action is still unknown.
