Objective: This study was conducted to compare serum Cytosolic β-Glucosidase (CBG) levels of age-matched control patients with those of infants with neonatal necrotizing enterocolitis (NEC), to determine eventual association between Serum Cytosolic β-Glucosidase levels with intensity of the disease in NEC infants.
Methods: 82 neonates were divided into controls (group I, n=41), feeding intolerance (group II, n=15), and NEC (group III, n=26). Serum Cytosolic β-Glucosidase was measured at the onset of feeding intolerance or NEC and at weeks 2-3 in control infants (Group I) by ELISA. Data were analyzed using descriptive statistics, non-parametric tests and Student t-test.
Findings: Median birth weights in three groups were 1761.3, 1951.9, 1893.7 g, median gestational ages were 33.6, 35.0 and 34.5 weeks and ages of sampling were 15.3, 14.7 and 15.1 days, respectively. The differences between NEC group, feeding intolerance group and the control group were not statistically significant (P>0.05). There was a trend toward an increase in Serum CBG levels (group I 36.5 nmmol/L), group II (112.4 nmmol/L) vs. group III (693.0 nmmol/L), (χ(2)=43.296, P<0.01). Infants in group III had highest CBG levels, compared with group II and I.
Conclusion: Serum CBG is elevated in NEC, maybe NEC is the reason of high level of Serum CBG. In addition, the serum CBG may have utility as an early marker of ischemia in patients at risk for NEC in future studies.

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.
Burn-induced mitochondrial dysfunction in hepatocytes: The role of methylation-controlled J protein silencing.

Background: Burn injuries trigger a systemic hyperinflammatory response, leading to multiple organ dysfunction, including significant hepatic damage. The liver plays a crucial role in regulating immune responses and metabolism after burn injuries, making it critical to develop strategies to mitigate hepatic impairment. This study investigates the role of methylation-controlled J protein (MCJ), an inner mitochondrial protein that represses complex I in burn-induced oxidative stress and mitochondrial dysfunction, using an in vitro Alpha Mouse Liver 12 cell model.

Intracellular delivery of proteins has attracted significant interest in biological research and cancer treatment, yet it continues to face challenges due to the lack of effective delivery approaches. Herein, we developed an efficient strategy cationic α-helical polypeptide-mediated anionic proprotein delivery. The protein was reversibly modified with adenosine triphosphate dynamic covalent chemistry to prepare an anionic proprotein (A-protein) with abundant phosphate groups.

Glomerular filtration rate (GFR) is the main functional index of kidney health and disease. Currently, no methods are available to directly measure tubular mass and function. Here, we report a serendipitous finding that the in vitro cell viability dye resazurin can be used in mice as an exogenous sensor of tubular function.

Background: Scutellaria baicalensis Georgi, a traditional Chinese herb, is known for its various biological effects, including antibacterial, anti-inflammatory, antioxidative, and antitumor properties. However, the function and mechanisms of methanol extract of Scutellaria baicalensis Georgi (MESB) in treating hepatic fibrosis remain unclear.
Methods: This study utilized a CCl4-induced mouse model of hepatic fibrosis to assess the effects of MESB through histopathological analysis and serum tests.
