The present study aims to evaluate the antioxidant and anxiolytic-like effect of Tualang honey in stressed ovariectomized (OVX) rats. The animals were divided into; (i) nonstressed sham-operated control rats, (ii) sham-operated control rats exposed to stress, (iii) nonstressed OVX rats, (iv) OVX rats exposed to stress, (v) OVX rats exposed to stress and treated with 17 β-oestradiol (E2) (20 μg daily, sc), and (vi) OVX rats exposed to stress and treated with Tualang honey (0.2 g/kg body weight, orally). The open field test was used to evaluate the anxiety-like behaviour and ELISA kits were used to measure oxidant/antioxidant status of the brain homogenates. The result showed that anxiety-like behavior was significantly increased in stressed OVX compared to other groups, and administering either E2 or Tualang honey significantly decreased anxiety-like behaviour in stressed OVX rats. The levels of malondialdehyde (MDA) and protein carbonyl (PCO) were significantly decreased while the levels/activities of superoxide dismutase (SOD), glutathione S-transferases (GST), glutathione peroxidase (GPx), and glutathione reductase (GR) were significantly increased in the brain homogenates of treated stressed OVX groups compared to untreated stressed OVX. In conclusion, Tualang honey has protective effects against brain oxidative stress and may be useful alternative anxiolytic agent especially for postmenopausal women.

Menopause occurs due to the depletion of the ovarian reserve, leading to a progressive decline in estrogen (E2) levels. This decrease in E2 levels increases the risk of developing several diseases and can coexist with chronic kidney disease (CKD). Arterial hypertension (AH) is another condition associated with menopause and may either contribute to or result from CKD.

Osteoporosis (OP) is a chronic inflammatory bone disease characterized by reduced bone structure and strength, leading to increased fracture risk. Effective therapies targeting both bone and cartilage are limited. This study compared the therapeutic effects of extracorporeal shockwave therapy (ESWT), bisphosphonate (Aclasta), and human Wharton jelly-derived mesenchymal stem cells (WJMSCs) in a rat model of OP.

Article Synopsis
- A-ring modifications in 1α,25-dihydroxyvitamin D enhance its binding to the vitamin D receptor (VDR) and increase its stability in cells by resisting metabolism, leading to longer-lasting effects.
- Various modified A-ring precursors synthesized from d-glucose showed specific biological activities with minimal calcemic side effects, including MART-10's potent antitumor effects in cancer models and AH-1's superior bone-forming properties in osteoporosis models compared to natural vitamin D.
- Ongoing research includes developing a library of fluorinated vitamin D analogs with potential anti-inflammatory effects and therapeutic applications for conditions like psoriasis, alongside the creation of the VDR-silent analog KK-052, which selectively inhibits SREBP/SC

Objective: Osteoporosis is a systemic disease with high morbidity and significant adverse effects. Increasing evidence supports the close relationship between oxidative stress and osteoporosis, suggesting that treatment with antioxidants may be a viable approach. This study evaluated the antioxidant properties of dichotomitin (DH) and its potential protective effects against osteoporosis.

Article Synopsis
- MZGW (Modified Zuo Gui Wan) combines traditional herbal treatment and red yeast rice, showing promise in treating osteoporosis (OP) through its effects on osteoclasts.
- Research utilized both in vivo (OVX rat model) and in vitro (RANKL-induced osteoclasts) experiments to understand MZGW's mechanisms, particularly focusing on the SCFA-GPR41-p38MAPK signaling pathway.
- Results indicated that the high-dose MZGW improved bone microstructure and inhibited osteoclast activity by changing gut flora metabolism and effectively regulating specific signaling pathways.
