Principle of brain within neurodevelopmental disorders: Beyond autistic variety disorder.

The activities of the antioxidant enzymes glutathione peroxidase (GPx), glutathione reductase (GRd) and catalase (CAT) were increased by LDAC treatment. Moreover, LDAC improved CCl4-induced hepatic vacuolization, necrosis and fibrosis in a dose-dependent manner, and no adverse effects were observed in the LDAC-treated groups. Based on the results, LDAC is a promising hepatoprotective agent for preventing and ameliorating CCl4-induced chronic liver injury, and this effect might be exerted through activation of the antioxidant defense system. © 2020 Center for Food and Biomolecules, National Taiwan University.

In the present investigation, antimicrobial potential of silver nanoparticles (AgNPs) of methanolic extract of Aegle marmelos fruit has been investigated. Agar well diffusion method was used for determining antimicrobial activity of solvent extracts (viz., petroleum ether, chloroform, acetone, methanol and aqueous), and AgNPs. Among these, methanolic extract of A. marmelos showed highest inhibitory activity against B. cereus (16.17 ± 0.50 mm) followed by P. aeruginosa (13.33 ± 0.62 mm) and E. coli. Phytochemical analysis of methanolic extract of A. marmelos revealed the presence of tannins, saponins, steroids, alkaloids, flavonoids, and glycosides. AgNPs synthesized using A. marmelos methanolic extract, characterized by UV-Visible spectroscopy, atomic force microscopy, dynamic light scattering, and X-ray diffraction showed a peak at 436 nm and size ranged between 159 and 181 nm. Evaluation of the antimicrobial potential of green synthesized AgNPs recorded the highest inhibitory activity against B. cereus (19.25 ± 0.19 mm) followed by P. aeruginosa (16.50 ± 0.30 mm) and S. dysentriae. The minimum inhibitory concentration (MIC) of synthesized AgNPs was found to be in the range of 0.009875-0.0395 mg/100 μl which was quite lower than the MIC of crude extract i.e. 0.0781-0.3125 mg/100 μl. The results obtained indicated that the different crude extracts of A. marmelos plant as well as AgNPs have a strong and effective antimicrobial potential that provide a marvelous source for the development of new drug molecules of herbal origin which may be used for the welfare of humanity. © 2020 Center for Food and Biomolecules, National Taiwan University.

BP has also been used as an herbal medicine to treat over 41 categories of disease in humans and animals. However, to date no long-term toxicity study of BP has been conducted in animals. In this study, 24-week oral toxicity of BP at doses of 0%, 0.5%, 2.5%, 5% and 10% of food was investigated in mice. Mortality, body weight, organ weight, food intake, water consumption, hematology, serum biochemistry, urinalysis, genotoxicity and organ histopathology of animals of both sexes were analyzed. No significant difference in the above parameters was observed between control and BP-fed mice except that body weight and food intake in those fed with 10% BP were significantly less than controls. In addition, similar results were seen in chickens fed with BP for 28 days. EGFR activity Collectively, the data demonstrate that BP has no adverse effects in mice and chickens at dose of 5% or less of food. © 2019 Center for Food and Biomolecules, National Taiwan University.

This study investigated Chinese herbal Medicine (CHM) for childhood asthma and clarified the relationship between CHM use and consequent asthma hospitalization by a population-based cohort study. Methods We used the data of one million individuals randomly selected from Registry of Beneficiaries of the National Health Insurance Research Database. Patients aged less than 18 years and diagnosed as asthma were followed from 2000 to 2012 and divided into the CHM group and the non-CHM group. Cox proportional hazard regression model was conducted to estimate the adjusted hazard ratio (aHR) of the two groups, and the Kaplan-Meier survival curve was used to determine the association between CHM cumulative days and consequent asthma hospitalization. Results Of the total of 33,865 patients, 14,783 (43.6%) were included in the CHM group, and 19,082 (56.4%) were included in the non-CHM group. After adjustment for gender, age, comorbidities, and total numbers of asthma medication, CHM users had a lower risk of asthma hospitalization than non-CHM users (aHR 0.90, 95% confidence interval [CI] 0.83-0.95). Children older than 6 years who used CHM therapy for more than 180 days exhibited a reduction of 29% for the risk of consequent asthma hospitalization (aHR 0.71, 95% CI 0.51-0.98). Conclusion Children aged 6-18 years who used more than 6 months CHM therapy reduced the risk of consequent asthma hospitalization. Long-term CHM therapy has benefit in school-age children with asthma. © 2019 Center for Food and Biomolecules, National Taiwan University.

The chondroprotective effect was also investigated using the chondrocyte cell line. First, MSE was prepared and analyzed for the amount of oxyresveratrol. EGFR activity The anti-inflammatory effects of MSE at various concentrations were evaluated through the inhibition of nitric oxide (NO), prostaglandin (PG)-E2 and cyclooxygenase (COX)-2 production. Oxyresveratrol at the equivalent amount found in the extract was investigated in the same manner. The chondroprotective effect was investigated through the suppression of MMP-13 production. The results showed that oxyresveratrol content in MSE was 15%. In RAW 264.7 cells, MSE (5-50 μg/mL) could inhibit the NO (24-30%) and PGE2 (11-82%) production. Oxyresveratrol at 0.75 and 7.5 μg/mL could suppress NO and also inhibited PGE2 but at only at high concentration.
