The onset of osteonecrosis of the femoral head (ONFH) is intimately associated with the extensive administration of glucocorticoids (GCs). Long-term stimulation of GCs can induce oxidative stress in both osteoclasts (OCs) and osteoblasts (OBs), resulting in the disturbance of bone remodelling. An alkaloid named crebanine (CN) demonstrates pharmacological properties including anti-inflammation and reactive oxygen species (ROS) modulation.

Introduction: In this study, the molecular mechanisms through which Lascorbate (Vitamin C) potentially treats Chronic Obstructive Pulmonary Disease (COPD) were identified. A non-targeted metabolomics analysis revealed metabolic disorders and significantly reduced levels of L-ascorbate in COPD patients compared to healthy subjects.
Method: The COPD rat model was established by exposing them to Cigarette Smoke (CS).

Poly(butylene succinate-co-furandicarboxylate) (PBSF) and poly(butylene adipate-co-furandicarboxylate) (PBAF) are novel furandicarboxylic acid-based biodegradable copolyesters with great potential to replace fossil-derived terephthalic acid-based copolyesters such as poly(butylene succinate-co-terephthalate) (PBST) and poly(butylene adipate-co-terephthalate) (PBAT). In this study, quantum chemistry techniques after molecular dynamics simulations are employed to investigate the degradation mechanism of PBSF and PBAF catalyzed by Candida antarctica lipase B (CALB). Computational analysis indicates that the catalytic reaction follows a four-step mechanism resembling the ping-pong bibi mechanism, with the initial two steps being acylation reactions and the subsequent two being hydrolysis reactions.

Aim: Our goal was to investigate the use of Cyclodextrin in creating an aqueous extract of Cinnamon with a high content of its bioactive ingredients, validated by cell-based assays.
Background: Due to their safety and cost-effectiveness, natural compounds have garnered attention for cancer therapy, which often faces challenges related to drug toxicity and resistance. Cinnamon (Cinnamomum verum; also known as Ceylon Cinnamon) is a commonly used spice with a history in folk medicine for treating various ailments.
Background: Increased osteoclast activity constitutes the primary etiology of excessive bone erosion in postmenopausal osteoporosis. ERp57, otherwise referred to as protein disulfide isomerase A3 (PDIA3), plays a crucial role in the regulation of intracellular calcium signaling. This is documented to exert a profound impact on osteoclast differentiation and functionality.

However, the preparation of pitch-based hard carbon (PHC) requires the aid of a pre-oxidation strategy, which introduces unnecessary defects and oxygen elements, which leads to low initial Coulombic efficiency (ICE) and poor cycling stability. Herein, we demonstrate a new surface engineering strategy by grafting chemically active glucose molecules on the PHC surface via esterification reactions, which can achieve low-cost nano-scaled carbon coating.

The assembled PR-LIB exhibits remarkable solar energy conversion efficiency alongside superior lithium storage capabilities. Without an electrical power supply, the photocharged PR-LIB sustained a discharge process for 63.

To address the challenges of flammability and hygroscopicity, composite coatings consisting of melamine (MEL), phytic acid (PA), cerium ions (Ce), and sodium laurate (La) are assembled on the FB surface through an in-situ impregnation strategy. The resulting MEL/PA-Ce@La FB exhibits exceptional flame retardancy.

This paper is an analytical study. Amateur athletes recruited by Beijing Hospital to participate in the 2022 Beijing Marathon and the 2023 Tianjin Marathon, and those who underwent health checkups at the Beijing Hospital Medical Checkup Center from January to June 2023 were selected as the study subjects, and 65 amateur marathon runners (41 males and 24 females) and 130 healthy controls (82 males and 48 females) were enrolled in the study according to the inclusion criteria.

A sample of 2129 older adults aged 60 and above who participated in the three waves of the Chinese longitudinal healthy longevity survey was used. QoL was measured using three indicators, including self-rated health, loneliness, and life satisfaction.

In recent years, obstacle detection technology based on LiDAR has been developed to identify potential issues, in which accurately extracting the track area is critical for segmentation and collision avoidance. However, because of the sparsity limitations inherent in LiDAR data, existing methods can only segment track regions over short distances, which are often insufficient given the speed and braking distance of urban rail trains.

Mild to moderate cases of NEC require medical treatment, whereas severe cases necessitate surgical intervention. However, evidence for surgical indications is limited and largely dependent on the surgeon's experience, leading to variability in outcomes.
