“…Ten water samples labeled A-J were collected from boreholes at different locations in Okada community and subjected to laboratory test to determine the pH, biological oxygen demand (BOD), chemical oxygen demand (COD),  dissolved oxygen (DO), hardness, turbidity, total organic carbon, total dissolved solids, electrical conductivity, and concentration of phosphates, nitrates, lead, sodium, calcium and chloride. The pH in the water samples is an indication of acidity and the WHO standard for pH value is specified within the range of 6.5-8.5. …”

Numerical analysis of factors causing long-term trends and annual variations of sulfur and nitrogen deposition amount in Japan from 2000 to 2020 by Satoru Chatani, Hikari Shimadera, Kyo Kitayama, Kazuya Nishina

“…Decreases caused by the reduction in anthropogenic NOx emissions in Japan were compensated for by increases caused by increasing NOx emissions in China and changes in the gas-aerosol partitioning of nitrates instead of sulfates. The decreasing trend in nitrogen deposition in Japan became statistically significant during the second half of the study period (2010–2020) after anthropogenic NOx emissions started to decline in China. …”

The Oral Mucosa Status and the Correlation between the Functional Parameters and the Level of Nitric Oxide Metabolites in Saliva among Patients with GERD by G. I. Lukina, A. V. Ivannikova, M. Y. Abramova, E. M. Kuzmina, A. V. Lukin, A. V. Alimova, A. B. Slabkovskaya

“…The objective assessment of the dental status of the examined patients included the measurement of the functional parameters of the mixed saliva, buffer capacity (BC) of saliva, and the detection of the nitric oxide metabolites (NOx) content in saliva from the right parotid salivary gland (“SRPSG”) and in blood serum using the indirect method based on the determination of the stable metabolites: nitrates and nitrites using the Griess reaction. It was established that salivation rate among patients with GERD with the prevailing of ACR and SACR was at the lower limit of normal values (0.32 + 0.19 ml/min), and the salivation rate among patients with the prevailing of SALCR was low (0.10 + 0.04 ml/min). …”

Comparison of chicoric acid, and its metabolites caffeic acid and caftaric acid: In vitro protection of biological macromolecules and inflammatory responses in BV2 microglial cells by Qian Liu, Fan Liu, Liling Zhang, Yajie Niu, Zhigang Liu, Xuebo Liu

“…Results showed that CA, CTA and CFA all significantly inhibited protein degradation and carbonylation induced by hydroxyl radicals and alcoxyl radicals, and suppressed hemin/nitrite/H2O2 triggered-nitration. Moreover, CA, CTA and CFA all exerted remarkable inhibition capacities on linoleic acid and soybean lecithin liposomes peroxidation in a dose-dependent manner, and restrained the oxidation of herring sperm DNA, as well as the breakage of pBR322 plasmid DNA. …”
