Triglyceride (TG) and its derivatives tend to be decreased in rheumatoid arthritis (RA) patients' blood when inflammation progresses. Aside from the role as a lipid buffer, white adipose tissue (WAT) contributes to this abnormality via adipokines, which regulate many metabolic signals. This work investigated adipokine-caused hepatic changes and their involvement in RA-related hypolipemia.

Article Synopsis
  • The study explored how the herbal formula Qing-Luo-Yin (QLY) affects SIRT1, a protein that regulates metabolism and immune responses, in a rat model of arthritis.
  • Treatment with QLY showed a significant reduction in fat in the liver and white adipose tissues of the rats, along with improved joint conditions and altered expression of certain SIRT1-related proteins.
  • The research concluded that inhibiting SIRT1 in adipose tissue helps reduce visfatin production in arthritis, which in turn may lessen inflammation, marking a possible anti-rheumatic mechanism of QLY that operates independently of immune regulation.

Purpose Of Review: Plant-based meat analogs (PBMAs) have been the subject of interest over the past few years due to consumers' demand for environmentally friendly, healthful, and non-animal-based foods. A better comprehension of the composition, structure, texture, nutrition, and sustainability of these PBMAs is necessary.

Recent Findings: This review articulates the protein sources and composition of PBMAs and their "meatiness" with respect to texture, structure, and flavor enhancement.

Biotransformation is a process in which molecules are modified in the presence of a biocatalyst or enzymes, as well as the metabolic alterations that occur in organisms from exposure to the molecules. Microbial biotransformation is an important process in natural product drug discovery as novel compounds are biosynthesised. Additionally, biotransformation products offer compounds with improved efficacy, solubility, reduced cytotoxic and allows for the understanding of structure activity relationships.

In this study, the antidiabetic activities of Lepionurus sylvestris Blume extract (LSB) in rats was investigated. The antidiabetic properties of LSB was evaluated using α-amylase, α-glucosidase and DPP-IV inhibitory assays, while the antioxidant assay was analysed using DPPH, ABTS and FRAP assays. Type 2 diabetes was with high-fructose/streptozotocin, and the diabetic animals were treated with LSB for 5 weeks.

Introduction: The fruit wastes, in particular agricultural wastes, are considered potential and inexpensive sources of bioactive compounds.

Objective: The current study was aimed at the preparation of an optimized extract of sugarcane bagasse using microwave-assisted extraction (MAE) technology and comparative evaluation of chemical composition, antioxidant, and antidiabetic activities with extract prepared through maceration technique.

Methodology: Box-Behnken Design (BDD) with response surface methodology was applied to observe interactions of three independent variables (ethanol concentrations [%], microwave power [W], and extraction time [min]) on the dependent variables (total phenolic content [TPC] and antioxidant status via 2,2-diphenyl-1-picrylhydrazyl [DPPH] to establish optimal extraction conditions.

Rheumatoid arthritis (RA) is a chronic inflammatory autoimmune disease that affects the joints of the human body and is projected to have a prevalence age-standardized rate of 1.5 million new cases worldwide by 2030. Several conventional and non-conventional preventive and therapeutic interventions have been suggested but they have their side effects including nausea, abdominal pain, liver damage, ulcers, heightened blood pressure, coagulation, and bleeding.

Article Synopsis
  • This study investigates the role of white adipose tissue (WAT) in rheumatoid arthritis (RA), suggesting it could be a potential target for treatment.
  • Researchers compared the WAT of healthy rats to those with adjuvant-induced arthritis (AIA) and found that AIA rats had smaller WAT but higher secretion levels of inflammatory proteins.
  • The study concludes that specific hepatokines enhance inflammatory responses in pre-adipocytes, which may worsen RA, indicating that targeting this dysfunction could help reduce the severity of the disease.

Milk may be consumed daily for the supply of essential nutrients in the body, however, depending on the source, milk may contain different concentrations of trace metals. The present study investigated the presence of trace metals in fresh milk purchased from different dairy farms and stores to determine the possible health risks to humans. A total of 15 fresh milk samples were purchased from various dairy farms (7 fresh milk samples) and stores (8 milk samples).

Type 2 diabetes is a major health concern contributing to most of diabetic cases worldwide. Mangiferin and its congeners are known for their diverse pharmacological properties. This study sought to investigate the inhibitory property of naturally occurring mangiferin congeners on sodium-glucose co-transporter 2 protein (SGLT-2) using comprehensive computational methods.

Article Synopsis
  • - The study evaluates the ecological toxicity of selected active pharmaceutical compounds (APCs) like lamivudine, ciprofloxacin, and sulfamethoxazole using three organisms: Allium cepa, Daphnia magna, and Salmonella typhimurium, across a concentration range of 10 to 100 ppb.
  • - Results indicated that individual exposure to these APCs led to high mortality rates in Daphnia magna, with sulfamethoxazole also showing mutagenic effects and lamivudine causing root growth issues in Allium cepa.
  • - The combined exposure to these pharmaceuticals produced a synergistic effect, revealing greater toxicity than individual compounds, which raises concerns about their environmental impact and potential

This study investigated the protective activities of pinostrobin (PIN) against methotrexate (MTX)-induced ovarian toxicity. Female rats were administered with PIN (50 mg/kg) for 4 weeks, while MTX was administered from weeks 2-4 of PIN treatment. Serum hormonal profiles, ovarian oxidative stress, inflammatory and apoptotic biomarkers as well as ovarian histomorphometry were evaluated.

Background: White adipose tissues (WAT) release large amounts of inflammatory mediators, which are responsible for the pathology of rheumatoid arthritis (RA).

Purpose: The current study investigated the involvement of WAT in the treatments of antigen-induced arthritis (AIA) mice with the herbal formula Qing-Luo-Yin (QLY).

Methods: Cytokines and biochemical/metabolic indicators were determined by ELISA and colorimetry methods, respectively.

Alcohol use disorder (AUD) continues to be a threat to public health due to the associated morbidity, mortality, and social and economic impacts. AUD accounts for greater than 85,000 deaths annually in the United States and greater than 1500 deaths annually in New Jersey (NJ). Despite these associated burdens, the treatment of AUD remains unequal among the population, and it is important to identify the factors influencing the disparity in defined population groups such as NJ to drive the appropriate intervention.

With the access-to-medicines conundrum facing its populations, the East African Community has adopted a policy framework which promotes a collective approach to resolving the access gap in the region. To this end, crucial policy documents on the implementation of TRIPS obligations, harmonisation of drug regulation and boosting regional manufacturing capacity have been adopted. This paper is a case study of the regional policy on the implementation of TRIPS obligations, specifically examining the extent to which partner states' implementation of TRIPS obligations mirrors the regional recommendations.
