Objectives: TObjectives: This study aims to investigate the effect of alendronate sodium on trabecular bone structure in an osteoporotic rat model.
Materials And Methods: Between May 2006 and July 2006, 60 female Wistar Albino rats aged three months were randomly allocated to three groups: sham operated receiving no treatment (Shm); ovariectomized-alendronate receiving 1 mg/kg/day alendronate sodium (Ovx-A), and ovariectomized-vehicle receiving 1 mL/kg/day physiological saline (Ovx-PS). Both Ovx groups received treatment through gastric gavage for 56 days.
Results: Densitometric measurements showed that bone mineral density decreased in the Ovx-PS and increased in Ovx-A groups (p<0.05). Biomechanical measurements showed a decrease in the breaking force in the Ovx-PS group and an increase in the Ovx-A group (p<0.05). Histomorphometric measurements showed that the Shm group had normal trabecular structure, while the Ovx-PS group had a less well- formed trabecular structure with a loss in the trabecular number and thickness and a corresponding increase in the trabecular spacing (p<0.05). In the Ovx-A group, there was an improvement in the trabecular structure with an increase in the trabecular number and thickness and a loss in the trabecular space (p<0.05).
Conclusion: Our study results suggest that alendronate sodium is a valuable treatment agent for osteoporosis in postmenopausal women.

Osteoporosis, a significant bone disease predominantly affecting elderly and postmenopausal women, leads to increased bone fragility and fracture risk, presenting a major public health concern with substantial socioeconomic implications. This study investigated the therapeutic potential of Lactobacillus strains, known for their immunomodulatory properties, in an ovariectomy-induced osteoporosis mouse model. Among three tested strains Lactobacillus casei GKC1, Lactobacillus rhamnosus GKLC1, and Lactobacillus johnsonii GKJ2, GKC1 demonstrated superior efficacy in promoting osteogenesis-related gene expression, including alkaline phosphatase (ALP), bone morphogenetic protein 2 (BMP2) and runt-related transcription factor 2 (RUNX2).

Background: Postmenopausal Osteoporosis (PMOP) is characterized by decreased bone mass and deterioration of bone microarchitecture, leading to increased fracture risk. Current treatments often have adverse effects, necessitating safer alternatives. Kaempferol, a flavonoid identified as a key active component of the traditional Chinese medicine Yishen Gushu formula, has shown promise in improving bone health, but its mechanisms in PMOP treatment remain unclear.

Bone is one of the most common target organs for distant metastases of solid tumors, which imposes a heavy burden on society. Early diagnosis of bone metastases is of great significance and positron emission tomography (PET) imaging plays an important role in the diagnosis of bone metastases. PET tracers applied for diagnosing bone metastases are constantly being updated, but they all have certain limitations like a relatively low bone/kidney ratio or no capacity to label therapeutic radionuclides.

Innumerable efforts are being made around the world for faster identification of therapeutic agents to treat the deadly disease. Post Acute Sequelae of SARS-CoV-2 infection or COVID-19 (PASC), also called Long COVID, is still being understood and lacks treatment options as well.

Osteoporosis is the most common systemic skeletal disorder, particularly associated with aging and postmenopausal women. With the growing knowledge about the gut-bone axis, the therapeutic strategies for osteoporosis have been shifted toward regulating gut microbiota to promote positive bone metabolism. Although GG (LGG) is widely reported to positively regulate bone metabolism by restoring the dysbiotic microbiome, oral administration is associated with sensitivity to gastric fluid and low bioavailability.
