Magnesium can prevent astrocyte cell death and Glial Fibrillary Acidic Protein (GFAP) secretion as inflammatory marker in preterm delivery. This study was performed to analyze differences in umbilical cord GFAP levels in preterm labor given magnesium sulfate (MgSO) as treatment group and control group and analyze the correlation between magnesium and calcium levels with umbilical GFAP levels. This quasi-experimental study was performed on 68 patients at Dr. Hasan Sadikin General Hospital from February-June 2021 consisting of 34 patients in each group. Maternal-umbilical cord magnesium levels, calcium levels, and GFAP levels were examined using ELISA test. The result was statistically measured by IBM SPSS 24.0. We found that there was a significant difference between maternal and umbilical magnesium levels and GFAP umbilical cord blood levels between the treatment and the control group (P < 0.05) in which GFAP level was higher in the control group. The multivariate analysis showed no significant relevance between mother magnesium and calcium level to umbilical cord GFAP level in the MgSO group. As conclusions, umbilical cord blood GFAP levels in preterm labor given MgSO were lower than in preterm deliveries who were not given MgSO. There was no correlation between magnesium, calcium, and GFAP levels in the treatment group.

Study Question: Is elevated plasma molybdenum level associated with increased risk for idiopathic premature ovarian insufficiency (POI)?
Summary Answer: Elevated plasma molybdenum level is associated with an increased risk of idiopathic POI through vascular endothelial injury and inhibition of granulosa cell proliferation.
What Is Known Already: Excessive molybdenum exposure has been associated with ovarian oxidative stress in animals but its role in the development of POI remains unknown.
Study Design, Size, Duration: Case-control study of 30 women with idiopathic POI and 31 controls enrolled from August 2018 to May 2019.

Secondary hyperparathyroidism (sHPT) is a significant clinical complication of CKD leading to bone abnormalities and cardiovascular disease. Current treatment based on activating the parathyroid calcium-sensing receptor (CaSR) using calcimimetics such as Cinacalcet, aims to decrease plasma PTH levels and inhibit the progression of parathyroid hyperplasia. In the present study, we found significant diurnal rhythmicity of Casr, encoding the Cinacalcet drug target in hyperplastic parathyroid glands (p = 0.

This study was an original article, mainly aimed to explore the influence of nutritional guidance during pregnancy on nutritional status and pregnancy outcome of pregnant women. Two hundred (200) pregnant women were admitted to the Nanjing General Hospital of Nanjing Military Command from May 2021 to May 2023. They were randomly sub-divided into a control group and an intervention group.

The activation of acid-sensing ion channel 1a (ASIC1a) in response to extracellular acidification leads to an increase in extracellular calcium influx, thereby exacerbating the degeneration of articular chondrocytes in rheumatoid arthritis (RA). It has been suggested that the inhibition of extracellular calcium influx could potentially impede chondrocyte ferroptosis. The cystine transporter, solute carrier family 7 member 11 (SLC7A11), is recognized as a key regulator of ferroptosis.

The phenomenon of fast and transient permeability of mitochondrial membranes by various triggers, known as permeability transition pore (mPTP) leads to the release of proapoptotic proteins and acts as an initial step in initiation of apoptosis. However, a role for mPTP was also suggested for physiology and it is unclear if there is a threshold in number of mitochondria with mPTP which induces cell death and how this mechanism is regulated in different tissues.
