AI Article Synopsis
Article Abstract
Background: Cholesteatoma is a proliferative disease that affects the tympanic cavity and temporal bone. Despite many studies and various theories, the etiopathogenesis of cholesteatoma has not been fully elucidated. Features such as invasion, migration, uncontrolled proliferation, and lack of differentiation are observed in both cholesteatoma and neoplasia.
Aims/objectives: The aim of this study is to investigate somatic genetic alterations in known proto-oncogenes and tumor suppressor genes in cholesteatoma.
Material And Methods: 60 different known proto-oncogenes and tumor suppressor genes were comparatively analyzed in cholesteatoma and peripheric blood samples from 15 middle ear cholesteatoma patients using next-generation sequencing.
Results: JAK3 c.2164G > A, TP53 c.284delC, and KRAS c.377A > T alterations were observed in cholesteatoma tissue but not in normal tissue. In addition, 12 different germline variants were also identified in 8 patients.
Conclusions And Significance: In this study, the presence of changes in cancer-related genes in cholesteatoma was determined and these changes were discussed in terms of possible clinical applications. We hope that the genetic alterations that emerged in this study, will be beneficial in guiding future research in this field.

Background: Whereas restoration of fecal consistency after treatment with clioquinol for chronic diarrhea and free fecal water syndrome has been attributed to its antiprotozoal properties, actions of clioquinol on the colonic bacterial microbiota have not been investigated.
Objectives: Characterize the dynamics of fecal microbial diversity before, during, and after PO administration of clioquinol to healthy horses.
Study Design: Experimental prospective cohort study using a single horse group.

Obesity is associated with changes in the gut microbiota, as well as with increased permeability of the intestinal wall. In 130 non-obese volunteers, 57 patients with metabolically healthy obesity (MHO), and 76 patients with metabolically unhealthy obesity (MUHO), bacterial DNA was isolated from stool samples, and the 16S rRNA gene was sequenced. The metabolic profile of the microbiota predicted by PICRUSt2 (https://huttenhower.

Polycystic ovary syndrome (PCOS) is associated with several mild metabolic disorders, including insulin resistance (IR), obesity, and dyslipidemia, as well as with some more severe ones, including type 2 diabetes mellitus, non-alcoholic fatty liver disease (NAFLD), and cardiovascular disease. Clinically, mild metabolic complications of PCOS such as IR or lipid metabolism disorders are the predictors of these more severe ones. So far, there is no reliable single marker that enables defining metabolic risk in patients with PCOS.

Alterations to the composition and function of neuronal nuclear pore complexes (NPCs) have been documented in multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis (ALS). Moreover, recent work has suggested that injury to the NPC can at least in part contribute to TDP-43 loss of function and mislocalization, a pathological hallmark of ALS and related neurodegenerative diseases. Collectively, these studies highlight a role for disruptions in NPC homeostasis and surveillance as a significant pathophysiologic event in neurodegeneration.

Background: Pancreatic adenocarcinoma (PDAC) exhibits a complex microenvironment with diverse cell populations influencing patient prognosis. Single-cell RNA sequencing (scRNA-seq) was used to identify prognosis-related cell types, and DNA methylation (DNAm)-based models were developed to predict outcomes based on their cellular characteristics.
Methods: We integrated scRNA-seq, bulk data, and clinical information to identify key cell populations associated with prognosis.
