The Role of Oligodendrocyte Lineage Cells in the Pathogenesis of Alzheimer's Disease.

Alzheimer's disease (AD) is a central nervous system degenerative disease with a stealthy onset and a progressive course characterized by memory loss, cognitive dysfunction, and abnormal psychological and behavioral symptoms. However, the pathogenesis of AD remains elusive. An increasing number of studies have shown that oligodendrocyte progenitor cells (OPCs) and oligodendroglial lineage cells (OLGs), especially OPCs and mature oligodendrocytes (OLGs), which are derived from OPCs, play important roles in the pathogenesis of AD.

Methods: Biomarkers were discerned through bulk-RNA and single-cell RNA sequencing (scRNA-Seq) investigations of IVDD cases from the Gene Expression Omnibus (GEO) database.

[Enzymatic reaction pattern of saponins in Gynostemma pentaphyllum and identification of their transformed products].

The activity of rare saponins is generally better than that of their prototypes. There are significant differences in the proportions and pharmacological effects of rare saponins/prototype saponins in Gynostemma pentaphyllum samples dried with different methods, which may be related to the reaction catalyzed by glucosidase. To explore the pattern of the enzymatic reaction catalyzed by glucosidase during the processing of G.

Association between the age-adjusted Charlson Comorbidity Index and complications after kidney transplantation: a retrospective observational cohort study.

Background: Complications following kidney transplantation elevate the risks of readmission and mortality. The aim of this study was to assess the association between the age-adjusted Charlson Comorbidity Index (ACCI) and postoperative complications among kidney transplant (KT) recipients.

Methods: Between January 2015 and March 2021, a study involving 886 kidney transplant recipients at the Third Affiliated Hospital of Sun Yat-sen University was conducted.

Conicity index and sex differences in relation to carotid plaque instability in Chinese community residents: Conicity index and carotid plaque.

Objectives: The conicity index (CI), an anthropometric parameter of visceral obesity, has exhibited a strong correlation with the incidence of atherosclerosis and cardiovascular events. This study aimed to explore the relationship between CI and carotid plaque instability, as well as the potential differences between sexes in this context.

Methods: Our cross-sectional study included a total of 44,248 participants from the China Stroke High-risk Population Screening and Intervention Program (CSHPSIP), all of whom underwent carotid ultrasound for the evaluation of carotid plaque.

Clinicopathological features and prognosis of alpha-fetoprotein-producing colorectal adenocarcinoma.

Aims: Alpha-fetoprotein (AFP)-producing colorectal adenocarcinoma (AFPCRA) is uncommon, with obscure clinicopathological features and prognosis.

Methods And Results: In this retrospective comparison study on surgically resected colorectal adenocarcinomas (CRA, n = 2389), we investigated and compared clinicopathological and prognostic features between AFPCRA cases with elevated pre-operative serum AFP levels, as the AFPCRA study group (n = 49, 2.1%), and the exact sex-, age- and stage-matched CRA cases as the control group at a 1:2 ratio during the study period from 2011 to 2021.

Fabrication, functionalization and applications of cellulose based aerogels: A review.

Cellulose based aerogels have recently gained a lot of interest in the past few years because of their sustainability, biocompatibility, biodegradability, and biosafety. Cellulose is an excellent raw material for the preparation of aerogels because of its advantages of strong renewability, low cost, good biocompatibility and easy degradation. The nanoscale cellulose can be prepared by physical, chemical and biological enzyme methods for the preparation of nanocellulose based aerogels (NCBAs).

Examining the role of common variants in rare neurodevelopmental conditions.

Although rare neurodevelopmental conditions have a large Mendelian component, common genetic variants also contribute to risk. However, little is known about how this polygenic risk is distributed among patients with these conditions and their parents nor its interplay with rare variants. It is also unclear whether polygenic background affects risk directly through alleles transmitted from parents to children, or whether indirect genetic effects mediated through the family environment also play a role.

Failure mode and effects analysis-based strategies for controlling multidrug-resistant organism infections in cancer patients.

In the context of advancing medical procedures, postoperative infections in cancer patients, particularly those involving multidrug-resistant organisms, have become a significant clinical concern. This study aims to comprehensively and systematically evaluate the effectiveness of infection prevention and control for multidrug-resistant organisms (MDROs) in postoperative cancer patients using Failure Mode and Effects Analysis (FMEA). This study was conducted in a tertiary A-level cancer specialty hospital in China, employing Failure Mode and Effects Analysis (FMEA) to assess the risks of hospital infections.

Differential proteomic profiles of exosomes in pediatric and adult adamantinomatous craniopharyngioma cyst fluid.

Background: Adamantinomatous craniopharyngiomas (ACPs), commonly seen in pediatrics and adults often present with large cystic cavities that can compress surrounding tissues, causing severe visual and endocrine symptoms. Complete resection of cystic ACP is challenging, frequently leading to postoperative recurrence. The composition of the cystic fluid is complex, and to date, there has been limited research focusing on exosomes within ACP cyst fluid.

Steroid-Refractory Myocarditis Induced by Immune Checkpoint Inhibitor Responded to Infliximab: Report of Two Cases and Literature Review.

Immune checkpoint inhibitors (ICIs), including anti-programmed cell death protein 1 and its ligand (PD-1/PD-L1) as well as anti-cytotoxic T lymphocyte-associated protein 4 (CTLA-4), have been widely used for treating solid tumors. Myocarditis is a potentially lethal immune-related adverse events (irAEs) caused by ICIs therapy. The treatment of steroid-refractory myocarditis is challenging.
