Investigation of the Soan River Water Quality Using Multivariate Statistical Approach by Zakaullah, Naeem Ejaz

“…The parameters dissolved oxygen (DO), biochemical oxygen demand (BOD), chemical oxygen demand (COD), turbidity, and total suspended solids (TSS) are among the prominent contributing variations in water quality, indicating that the water quality of the Soan River deteriorates gradually as it passes through the urban areas, receiving domestic and industrial wastewater from the outfalls. …”

Lysine Reacts with Cholesterol Hydroperoxide to Form Secosterol Aldehydes and Lysine-Secosterol Aldehyde Adducts by George Wafula Wanjala, Arnold Nola Onyango, David Rasugu Abuga, John Kamathi Muchuna, Calvin Onyango, Moses Makayoto

“…However, it was recently postulated that primary amines such as lysine may catalyse their formation from cholesterol-5α-hydroperoxide (Ch-5α-OOH), the main product of the oxidation of cholesterol with singlet oxygen. This involves cyclization of Ch-5α-OOH to an unstable dioxetane intermediate, which decomposes to form secosterol aldehydes with triplet carbonyl groups, whose return to the singlet state is at least partly coupled to the conversion of triplet molecular oxygen to singlet oxygen. …”

COVID-19 in Patients with Primary Biliary Cholangitis by М. К. Prashnova, K. L. Raikhelson, N. V. Marchenko, S. M. Zakharenko

“…Mild COVID-19 was observed in 34 (68 %) people, moderate course — in 14 (28 %), severe — in 2 (4 %), cases of extremely severe course were not recorded. 12 patients were hospitalized, 8 of which received oxygen therapy due to a decrease in SpO2 < 94 %, there was no need for the use of other methods of oxygen therapy in any case. …”

Analysis of the Internal Radial Gradient of Chemical Abundances in Spiral Galaxies from CALIFA by A. F. S. Cardoso, O. Cavichia, M. Mollá, L. Sánchez-Menguiano

“…Additionally, we analyze the abundance radial gradients to investigate the impact of diffuse ionized gas (DIG) decontamination on oxygen abundances over these inner drops. We observe that DIG, concentrated mainly in the central regions of galaxies, can modify oxygen abundance gradient profiles if left unaddressed.…”

A Single-Cell Approach in Modeling the Dynamics of Tumor Microregions by Katarzyna A. Rejniak

“…Interactions between tumor cells and their environment lead to the formation of microregions containing nonhomogeneous subpopulations of cells and steep gradients in oxygen, glucose, and other metabolites. To address the formation of tumor microregions on the level of single cells, I propose a new two-dimensional time-dependent mathematical model taking explicitly into account the individually regulated biomechanical processes of tumor cells and the effect of oxygen consumption on their metabolism. …”
