Biodegradable material, such as magnesium alloy or polylactic acid (PLA), is a promising candidate for orthopedic surgery. The alloying of metals and the addition of rare earths to increase mechanical strength are still questionable in terms of biosafety as absorbent materials. Therefore, the purpose of this study is to understand the effect of substances due to the degradation of various biodegradable substances on organs in the body or surrounding tissues.

Article Synopsis
  • - Benign prostatic hyperplasia (BPH) is primarily a urinary tract issue in older males, and this study evaluated the anti-proliferative effects of two natural extracts, CR and Syzygium aromaticum (SA), on BPH symptoms in lab tests with cells and rats.
  • - Experimental results indicated that the combination of CR and SA extracts significantly reduced cell proliferation and various biomarkers related to BPH when tested on RWPE-1 cells and testosterone-induced BPH rats, showing promising effects compared to individual extracts.
  • - The study concludes that the CR and SA extracts may help alleviate BPH symptoms through their anti-inflammatory and antioxidant properties, supporting their potential as natural treatment options.

Periodontitis is an infectious inflammation in the gums characterized by loss of periodontal ligaments and alveolar bone. Its persistent inflammation could result in tooth loss and other health issues. Ixeris dentata (IXD) and Lactobacillus gasseri media (LGM) demonstrated strong antioxidant activity, which may prevent oxidative and inflammatory periodontitis.

Liver injury can be acute or chronic, resulting from a variety of factors, including viral hepatitis, drug overdose, idiosyncratic drug reaction, or toxins, while the progression of pathogenesis in the liver rises due to the involvement of numerous cytokines and growth factor mediators. Thus, the identification of more effective biomarker-based active phytochemicals isolated from medicinal plants is a promising strategy to protect against CCl-induced liver injury. L.

Polyphenols and other compounds with antioxidant properties are found in plants and are one of the main antioxidants proven to reduce body weight and the risk of insulin resistance. Still, the mechanism behind the protective effects against obesity remains unclear. Thus, the study aims to assess the impact of flavonoid-rich arriheuk extract, a purple wheat extract, on mitochondrial function using 3T3-L1 adipocytes and investigate the molecular mechanism behind its protective effects against adipogenesis and lipolysis.

Activating brown adipose tissue (BAT) and stimulating white adipose tissue (WAT) browning is a prospective obesity treatment method. Dietary components derived from plants are the most effective approach to activate BAT and promote WAT browning in rodents. This study investigated the synergistic effects of (PG) and leaf (DKL) extract on adipocyte differentiation and browning, as well as the molecular mechanism underlying their beneficial effects.

Article Synopsis
  • The study aimed to create bioactive biocomposites using decellularized extracellular matrix (dECM) and calcium phosphate, assessing their impact on the differentiation of human dental pulp stem cells (hDPSCs).
  • High-quality cell-laden 3D biocomposites were successfully produced, with over 90% cell viability and stable printing properties, leading to positive evaluations of cytotoxicity and cell differentiation.
  • Results indicated that dECM-based biocomposites significantly enhance osteogenic activity and promote odontogenic differentiation in hDPSCs, with successful tissue formation observed after implantation in mice, suggesting potential for use in dental tissue engineering.
