Objective: This study was undertaken to determine the prevalence, epidemiology, and mother-child repercussions of increased alanine-aminotransferase levels from week 16 of pregnancy.
Study Design: A longitudinal observational study of 381 pregnant women. The cause of increased alanine-aminotransferase levels during pregnancy and repercussions on the neonate were studied in 283 cases. Statistical analysis was performed with Mann-Whitney test, chi2 test, or the Fisher exact test.
Results: The mean age of the mothers was 29.9 +/- 4.8 years. Twenty-five percent presented increased gamma-glutamyl-transpeptidase, alkaline phophatase, and dehydrogenase lactate from week 32. Increased alanine-aminotransferase was observed in 7.4% (95% CI, 5.00%-10.57%) of cases. Clinical disorders were light, transitory, and with no apparent cause, except for 1 hemolysis, elevated liver enzymes, low platelets (HELLP) syndrome, 3 preeclampsias, and 1 gravidic cholestasis. No statistically significant differences were observed in the group of mother-child with alanine-aminotransferase normal or increased.
Conclusion: Most increases in alanine-aminotransferase from week 16 of pregnancy are transitory, non-specific, and have no repercussions on mother or child.

A preclinical study on effect of betanin on sodium fluoride induced hepatorenal toxicity in wistar rats.
J Complement Integr Med
January 2025
Department of Basic Medical Sciences, Manipal, Manipal Academy of Higher Education, Manipal, Karnataka, India.
Article Synopsis
- Excessive fluoride exposure can cause oxidative stress and damage metabolic organs, leading to toxicity in the liver and kidneys.
- A study was conducted on Wistar rats divided into four groups, with some receiving sodium fluoride alone and others receiving fluoride with different doses of betanin from beetroot for 90 days.
- Results showed that betanin treatment reduced markers of liver and kidney damage and improved oxidative stress indicators, suggesting it could potentially protect against fluoride-induced organ toxicity.
Effects of prolonged oxytetracycline supplementation on freshwater stinging catfish (): a multi-biomarker approach.

Background: Aquaculture systems that sporadically depend on antibiotics can contribute to the development of adverse effects on the fish, microbial flora and the environment. This study sought to investigate the impacts of extended oxytetracycline supplementation on the freshwater stinging catfish through a multi-biomarker approach.
Methods: A total of 300 (20 ± 0.
The influence of ammonia-N and salinity levels on oxidative stress markers, hepatic enzymes, and acid phosphatase activity in Nile tilapia (Oreochromis niloticus).

The point of our study was to examine the interaction of ammonia-N poisoning and salinity on serum enzymes and oxidative stress factors of blood and liver in Nile tilapia (Oreochromis niloticus). The 50% lethal concentration (LC) in 96 h was 0.86 mg/L of ammonia-N.

Article Synopsis
- The study explored the impact of Isalo scorpion cytotoxic peptide (IsCT) on growth, immunity, and gut bacteria in yellow-feathered broilers, using a controlled diet experiment over 60 days.
- Results indicated that higher doses of IsCT (150 and 200 mg/kg) led to significantly greater body weight and daily weight gain compared to the control group, alongside improved feed conversion ratios.
- Immune function was positively affected, with increased IgA and IgG levels in groups receiving IsCT, and gut microbiota analysis revealed notable changes in microbial populations compared to the control group.
Increased ferritin, serum lactate dehydrogenase, and aspartate aminotransferase levels predict macrophage activation syndrome complicating systemic lupus erythematosus: a retrospective study.

Department of Rheumatology and Immunology, Children's Hospital of Nanjing Medical University, Nanjing, China.
Background: This study aimed to assess the diagnosis of macrophage activation syndrome (MAS) at the onset of active childhood-onset systemic lupus erythematosus (cSLE), which is under-researched, and to compare the characteristics of cSLE with and without MAS, hypothesizing the existence of possible predictors of MAS in active cSLE.
Methods: This study enrolled 157 patients diagnosed with cSLE, with or without MAS, from Nanjing Medical University between January 2018 and May 2023. Data analysis was performed using an independent samples -test or the Mann-Whitney -test, the test, the Youden index to determine the optimal cutoff values for diagnosis, and binary logistic regression analysis to determine the predicted probability.
