Exploration in association between vitamin D, sleep quality, and osteoarthritis: A modeling study.

Previous studies on the relationship between vitamin D, sleep quality, and osteoarthritis (OA) have been controversial and the aim of this study is to analyze the association. In this study, relevant data from 2 survey cycles (2009-2010 with 2011-2012) are downloaded from the CDC's NHANES project to analyze the relationship between vitamin D, sleep quality, and osteoarthritis, as well as other related risk factors. The analysis of statistics in this study is performed using t-tests and chi-square tests, modeling is performed using logistic regression based on NHANES weights, and other risk factors are analyzed using forest plots.

Troglitazone reduces intracellular Mycobacterium tuberculosis survival via macrophage autophagy through LKB1-AMPKα signaling.

Tuberculosis (TB) caused by Mycobacterium tuberculosis (Mtb), results in significant morbidity and mortality worldwide. Host-directed therapy (HDT), including conventional drugs, is a promising anti-TB strategy that shows synergistic antibacterial effects when combined with anti-TB drugs. Here, the mycobactericidal effect of three anti-diabetic drugs was examined.

Involvement of GSTP1 in low dose radiation-induced apoptosis in GM12878 cells.

Background: Low-dose ionizing radiation-induced protection and damage are of great significance among radiation workers. We aimed to study the role of glutathione S-transferase Pi (GSTP1) in low-dose ionizing radiation damage and clarify the impact of ionizing radiation on the biological activities of cells.

Results: In this study, we collected peripheral blood samples from healthy adults and workers engaged in radiation and radiotherapy and detected the expression of GSTP1 by qPCR.

MDM2-p53 mediate a miR-181c-3p/LIF axis to regulate low dose-rate radiation-induced DNA damage in human B lymphocytes.

Purpose: Prolonged exposure to low dose-rate radiation (LDRR) is of growing concern to public health. Recent evidences indicates that LDRR causes deleterious health effects and is closely related to miRNAs. The aim of our study is to investigate the relationship between miRNAs and DNA damage caused by LDRR.

One-step quaternization and macromolecular reconstruction to prepare micro-/nano-porous cellulose beads from homogeneous solution for low-concentration amoxicillin removal.

Designing advanced functional cellulose-based materials by one-step homogeneous preparation technology is a great challenge since cellulose is insoluble in common solvents or difficult to regenerate and shape. Quaternized cellulose beads (QCB) were prepared from a homogeneous solution by one-step cellulose quaternization homogeneous modification and macromolecules' reconstruction technology. Morphological and structural characterizations of QCB were conducted by SEM, FTIR and XPS, etc.

Gut microbiota and ionizing radiation-induced damage: Is there a link?

According to observational findings, ionizing radiation (IR) triggers dysbiosis of the intestinal microbiota, affecting the structural composition, function, and species of the gut microbiome and its metabolites. These modifications can further exacerbate IR-induced damage and amplify proinflammatory immune responses. Conversely, commensal bacteria and favorable metabolites can remodel the IR-disturbed gut microbial structure, promote a balance between anti-inflammatory and proinflammatory mechanisms in the body, and mitigate IR toxicity.

Protection of the hematopoietic system against radiation-induced damage: drugs, mechanisms, and developments.

Sometimes, people can be exposed to moderate or high doses of radiation accidentally or through the environment. Radiation can cause great harm to several systems within organisms, especially the hematopoietic system. Several types of drugs protect the hematopoietic system against radiation damage in different ways.

Metabolomics as a valid analytical technique in environmental exposure research: application and progress.

Background: In recent years, studies have shown that exposure to environmental pollutants (e.g., radiation, heavy metal substances, air pollutants, organic pollutants) is a leading cause of human non-communicable diseases.

pH-Responsive Cellulose-Based Microspheres Designed as an Effective Oral Delivery System for Insulin.

Functional modified cellulose microsphere (CMs) materials exhibit great application potential in drug various fields. Here, we designed pH-responsive carboxylated cellulose microspheres (CCMs) by the citric/hydrochloric acid hydrolysis method to enhance oral bioavailability of insulin by a green route. The CMs were high purity cellulose that dissolved and regenerated from a green solvent by the green sol-gel method.

MicroRNA: a novel implication for damage and protection against ionizing radiation.

Ionizing radiation (IR) is a form of high energy. It poses a serious threat to organisms, but radiotherapy is a key therapeutic strategy for various cancers. It is significant to reduce radiation injury but maximize the effect of radiotherapy.

Functionalized phosphorylated cellulose microspheres: Design, characterization and ciprofloxacin loading and releasing properties.

In this work, functionalized phosphorylated cellulose microspheres (CMP) were designed as a carrier for the ciprofloxacin (CIP) drug delivery system. The CMP has been developed from cellulose microspheres (CM) and phosphoric acid via an esterification reaction. CIP, an antibiotic drug as a model, was loaded onto CIP via hydrogen bonds and electrostatic interactions.

iTRAQ-Based Proteomic Profiling of Potential Biomarkers in Rat Serum for Uranium Tailing Suspension Intratracheal Instillation.

Protection against low-dose ionizing radiation is of great significance. Uranium tailings are formed as a byproduct of uranium mining and a potential risk to organisms. In this study, we identified potential biomarkers associated with exposure to low-dose radiation from uranium tailings.
