Knockdown of MiD49 and MiD51 alleviates collagen-induced arthritis and suppresses mitophagy and fatty acid oxidation (FAO) in rheumatoid arthritis fibroblast-like synoviocytes.

Increasing evidence confirms that imbalances in mitochondrial dynamics can impair mitochondrial function, thereby disrupting cellular homeostasis and potentially contributing to a variety of diseases. This study investigated whether mitochondrial dynamics proteins of 49 and 51 kDa (MiD49 and MiD51, MiDs) contribute to the maintenance of the abnormal functions of fibroblast-like synoviocytes (FLS), thereby participating in the pathological process of rheumatoid arthritis (RA), and to elucidate the specific mechanisms. We found that MiDs were significantly upregulated in the FLS of synovial tissues from RA patients and collagen-induced arthritis (CIA) models, as well as in the serum of RA patients.

MiR-371b-5p reduces osteosarcoma cell migration and proliferation to induce apoptosis by targeting FUT4.

In our previous study (PMID: 34671604), we found that miR-317b-5b not only exerted anti-tumor effect, but also downregulated FUT4 expression in human myeloma cell line 143B. This study aims to investigate the biological function of miR-371b-5p in osteosarcoma progression and the role of FUT4 in this process. For investigations, the human osteosarcoma cell lines (SaOS2, 143B, KHOS and U2OS) as well as the human osteoblast cell line (hFOB1.

Background: Magnesium is an essential immune nutrient for the body, and recent studies have found that it plays an important role in osteoarthritis (OA). Magnesium depletion score(MDS) is a new method for evaluating the magnesium status of the body. Our objective is to explore the association between MDS and the incidence of OA, as well as the relationship between MDS and mortality in patients with OA.

Association between pan-immune-inflammation value and coronary heart disease in elderly population: a cross-sectional study.

Background: Systemic inflammation, immune and nutrition status are closely linked to the occurrence and development of coronary heart disease (CHD). Pan-immune-inflammation value (PIV) is a new method for evaluating systemic inflammation and immune status. Our objective is to explore the connection between PIV and CHD especially in elderly people, as well as the diagnostic value of PIV combined with controlling nutritional status (COUNT) score for CHD.

Objectives: This study aimed to use bidirectional two-sample Mendelian randomization (TSMR) analysis to explore the causal relationship between gut microbiota and aging.

Exploring rural middle school music teachers' classroom interaction decision-making levels: A student's perspective.

This study explores students' perceptions of rural middle school music teachers' decision-making levels in the context of classroom interactions. Using a questionnaire survey of 246 students from a rural public middle school and follow-up interviews, we investigate students' overall perceptions and examine differences among students of different genders, grades, and music study experiences. The results indicate that students generally perceive teachers' decision-making levels to be slightly above average, with no significant differences between male and female students or among different grade levels in their perceptions of teacher decision-making levels.

Effects of protein grass hay as alternative feed resource on lamb's fattening performance and meat quality.

Protein grass hay (PGH) was used as a new feed source for lambs to study its effect on fattening performance and meat quality. Fifty-six male lambs were allotted to four experimental groups and fed for eight weeks either alfalfa hay (AH)-based diet (control) or diets in which AH was replaced with 33 %, 66 %, or 99 % PGH. The inclusion of PGH did not affect final body weight, dry matter intake, average daily gain, feed conversion ratio, or carcass weight.

Electrooxidative Iridium-Catalyzed Regioselective Annulation of Benzoic Acids with Internal Alkynes.

Electrochemically driven, Cp*Ir(III)-catalyzed regioselective annulative couplings of benzoic acids with alkynes have been established herein. The combination of iridium catalyst and electricity not only circumvents the need for stoichiometric amount of chemical oxidant, but also ensures broad reaction compatibility with a wide array of sterically and electronically diverse substrates. This electrochemical approach represents a sustainable strategy as an ideal alternative and supplement to the oxidative annulations methodology to be engaged in the synthesis of isocoumarin derivatives.

The exploitation of efficient hydrogen evolution reaction (HER) electrocatalysts has become increasingly urgent and imperative; however, it is also challenging for high-performance sustainable clean energy applications. Herein, novel CoS nanoparticles embedded in a porous N,S-dual doped carbon composite (abbr. CoS@NS-C-900) were fabricated by the pyrolysis of a single crystal Co-MOF assisted with thiourea.

Inhibitory effect of sixteen pharmaceutical excipients on six major organic cation and anion uptake transporters.

To date, relatively little is known about the interactions of pharmaceutical excipients with hepatic and renal drug uptake transporters. The present study was designed to systematically evaluate the effects of 16 commonly consumed excipients on human organic cation transporter 1 and 2 (hOCT1 and hOCT2), human organic anion transporter 1 and 3 (hOAT1 and hOAT3) and human organic anion transporting polypeptide 1B1 and 1B3 (hOATP1B1 and hOATP1B3). The inhibitory effects and mechanisms of excipients on transporters were investigated using uptake studies, cell viability assays, concentration-dependent studies, and the Lineweaver-Burk plot method.

Comparative toxicity analysis of corannulene and benzo[a]pyrene in mice.

Increasing production of corannulene (COR), a non-planar polycyclic aromatic hydrocarbon (PAH) with promising applications in many fields, has raised a concern about its potential toxic effects. However, no study has been undertaken to evaluate its metabolism and toxicity in mammals. In this study, the acute toxicities of COR in mice were compared with benzo[apyrene (BaP), a typical planar PAH with almost the same molecular weight.

Involvement of aryl hydrocarbon receptor in the cytotoxicity of corannulene and its derivatives.

Despite numerous studies on the toxicities of planar polycyclic aromatic hydrocarbons (PAHs), very little is known about the toxicological profiles of non-planar PAHs. In the present study, the cytotoxicity of corannulene (COR), a typical bowl-shaped PAH with a myriad of applications in the area of material chemistry, and benzo[a]pyrene (BaP), a typical planar PAH with similar molecular weight, were systematically compared in various cell lines. Compared with BaP, exposure to COR resulted in less cytotoxic responses in both human (HepG2) and murine (Hepa1-6) hepatoma cells, which was characterized with a slower cellular accumulation as well as a weaker induction of cytochrome P450 1 (CYP1/Cyp1) isozymes.

Glucocorticoids Increase Renal Excretion of Urate in Mice by Downregulating Urate Transporter 1.

Both nonsteroidal anti-inflammatory drugs (NSAIDs) and glucocorticoids have been widely used for the treatment of gout, a disease promoted by an excess body burden of uric acid (UA); however, their effects on the homeostasis of UA remain poorly understood. The present study showed that 1-week treatments with three NSAIDs (ibuprofen, diclofenac, and indomethacin) had little effect on UA homeostasis in mice, whereas 1-week low doses (1 and 5 mg/kg) of dexamethasone (DEX) significantly decreased serum UA by about 15%. Additionally, low doses of DEX also resulted in increases in hepatic UA concentration and urinary UA excretion, which were associated with an induction of xanthine oxidoreductase (XOR) in the liver and a downregulation of urate transporter 1 (URAT1) in the kidney, respectively.

Dihydrophenanthrenes from Juncus effusus as Inhibitors of OAT1 and OAT3.

Organic anion transporters 1 (OAT1) and 3 (OAT3) play important roles in the renal elimination of a range of substrate molecules. Little is known about natural products that can modulate OAT1 and OAT3 activities. The medullae of Juncus effusus is often used for the treatment of dysuria in traditional Chinese medicine.
