AI Article Synopsis
- This study investigated bone turnover markers in pregnant women and their relation to preeclampsia.
- A total of 140 women were monitored, comparing those who developed preeclampsia with those who had uncomplicated pregnancies.
- Results showed that women with preeclampsia had significantly higher levels of a bone resorption marker at delivery, while other markers remained unchanged, indicating that bone turnover may be altered during pregnancy in the context of preeclampsia.
Article Abstract
Aim: This prospective study aims to investigate the levels of bone turnover markers in pregnancy and correlate it with the assessment of preeclampsia.
Methods: A total of 140 women were followed up during their pregnancy. The women who developed preeclampsia (n=22), were compared with age-matched women (controls) who did not develop preeclampsia and had an uncomplicated pregnancy (n=22). Maternal serum levels of serum bone-specific alkaline phosphatase (sBAP), a marker of bone formation, and N-telopeptide of type 1 collagen (NTx), a marker of bone resorption, were estimated at recruitment (in the second trimester) and at delivery. sBAP and NTx levels were measured by enzyme immunoassay (EIA) and enzyme linked immunosorbent assay (ELISA), respectively. Serum and urinary calcium titers were compared by using a commercially-available calcium assay kit.
Results: Serum NTx levels increased significantly during pregnancy (P<0.02) and were significantly higher at delivery (P<0.01) in women with preeclampsia compared with controls. The levels of sBAP and serum calcium did not change significantly in both groups during pregnancy. There was no significant correlation between sBAP and NTx with maternal factors. A negative correlation was observed between sBAP and NTx levels in the preeclamptic group.
Conclusions: Biochemical markers of bone turnover are greater in preeclampsia compared with normal pregnancy only when the disease is clinically evident (at delivery).

The underlying mechanisms of the association of bone health with depression - an experimental study.

Background: Depression constitutes a risk factor for osteoporosis, but underlying molecular and cellular mechanisms are not fully understood. MiRNAs influence gene expression and are carried by extracellular vesicles (EV), affecting cell-cell communication.
Aims: (1) Identify the difference in miRNA expression between depressed patients and healthy controls; (2) Analyze associations of these miRNAs with bone turnover markers; (3) Analyze target genes of differentially regulated miRNAs and predict associated pathways regarding depression and bone metabolism.

The skeleton is highly innervated by numerous nerve fibers. These nerve fibers, in addition to transmitting information within the bone and mediating bone sensations, play a crucial role in regulating bone tissue formation and regeneration. Traditional bone tissue engineering (BTE) often fails to achieve satisfactory outcomes when dealing with large-scale bone defects, which is frequently related to the lack of effective reconstruction of the neurovascular network.

Background: The clinical evidence about alveolar ridge changes following molar extraction and how the alveolar bone morphology influences the ridge dimensional changes remains limited.
Methods: A total of 192 patients with 199 molar extractions were included in this retrospective study. Cone-beam computed tomography (CBCT) images of patients were obtained 0-3 months pre extraction and 6-12 months post extraction.
Background: Targeting glutamine metabolism has emerged as a promising strategy in cancer therapy. However, several barriers, such as anti-tumor efficacy, drug toxicity, and safety, remain to be overcome to achieve clinical utility. Prior preclinical studies had generated encouraging data showing promises of cancer metabolism targeting drugs, although most were performed on immune-deficient murine models.

Exosomes, small extracellular vesicles secreted by various cells, play crucial roles in the pathogenesis and treatment of oral diseases. Recent studies have highlighted their involvement in orthodontics, periodontitis, oral squamous cell carcinoma (OSCC), and hand, foot, and mouth disease (HFMD). Exosomes have a positive effect on the inflammatory environment of the oral cavity, remodeling and regeneration of oral tissues, and offer promising therapeutic options for bone and periodontal tissue restoration.
