Background And Aims: Oral microbiota may contribute to the development of upper gastrointestinal (UGI) disorders. We aimed to study the association between the microbiome of saliva, subgingival and buccal mucosa, and UGI disorders, particularly precancerous lesions. We also aimed to determine which oral site might serve as the most effective biomarker for UGI disorders.

We present Enterocytozoon bieneusi infection in four patients with autoimmune diseases undergoing prolonged monoclonal antibody therapies. Two patients suffered from inflammatory bowel disease and received anti-TNF therapies, whereas two other patients suffered from systemic lupus erythematosus with renal involvement and received anti-CD20 or anti-BLyS protein therapies. Three out of four patients consulted for diarrhea with abdominal pain without intestinal inflammation or bleeding at the time of sampling.

Mutations in the exonuclease domains of the replicative nuclear DNA polymerases POLD1 and POLE are associated with increased cancer incidence, elevated tumor mutation burden (TMB), and enhanced response to immune checkpoint blockade (ICB). Although ICB is approved for treatment of several cancers, not all tumors with elevated TMB respond, highlighting the need for a better understanding of how TMB affects tumor biology and subsequently immunotherapy response. To address this, we generated mice with germline and conditional mutations in the exonuclease domains of Pold1 and Pole.

Hypertension is a major risk factor for many cardiovascular diseases, which can lead to kidney and heart disease, stroke, and premature death. Inhibiting angiotensin-converting enzyme (ACE) activity is an effective method to relieve hypertension. Previously, we screened an active peptide KYPHVF (KF6) from Boletus griseus-Hypomyces chrysospermus with excellent ACE inhibitory activity.

Background: Lamin A is barely expressed in human brain neurons or in murine models such as mice and rats. However, in Alheimer´s disease (AD) brains, neurons in the hippocampus and entorhinal cortex abnormally express lamina A from the initial stages of the disease, being a biomarker together with phosphorylated Tau of the nuclear pathology of AD. Constipation and mesenteric neuronal loss are related to aging and neurodegenerative diseases such as AD.
