Published: July 2021

Thymus numidicus Poir. (Lamiaceae) is a native plant of northern Algeria and Tunisia. It is used in traditional medicine in Algeria to treat respiratory and digestive diseases, and as a spice in food preparations. This study aimed to characterize the chemical constituents and to evaluate antibacterial and antioxidant activities of 1-butanol (BuOH) extract of aerial parts of T. numidicus. A total of 15 phenolic compounds were identified using HPLC-TOF/MS analysis, among them eight phenolic acids, five flavonoids and a stilbenoid glycoside named polydatin, which were reported for the first time from the species. Antibacterial effects of BuOH extract were determined using the disc diffusion method against four bacteria strains, where it has displayed a weak activity against three of them. In addition, BuOH extract showed significant antioxidant activity, which was measured using 1,1-diphenyl-2-picrylhydrazyl, 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) assays for free radical scavenging activity, and cupric ion reducing antioxidant capacity assay. Our results suggest the use of T. numidicus as a natural antioxidant in food and pharmaceutical industries.
Therapeutic potential of L-arginine in a rat model of ovarian ischemia-reperfusion injury

Published: July 2021

Ischaemia-reperfusion (I/R) injury is a serious problem subsequent to reperfusion treatment for ovarian torsion. The role of nitric oxide (NO) in ovarian I/R injury is debatable. The main focus of this study was to explore the protective role of L-arginine, a potent NO precursor, on ovarian I/R injury. Female Wistar rats were divided into three groups (n = 5). In the control group, only laparotomy was performed. In the I/R group, ischaemia and reperfusion were performed and no drug was given. In the I/R + arginine group, ischaemia was followed by reperfusion and 200 mg kg L-arginine was injected 5 min before reperfusion. Concentration of malondialdehyde, NO and reduced glutathione, as well as activity of superoxide dismutase and catalase were analyzed. Hematoxylin and eosin-stained slides were microscopically examined for histological evaluation of the ovaries. Superoxide dismutase and catalase activity along with concentration of reduced glutathione and NO were significantly lower in the I/R group in comparison to the control group. Malondialdehyde concentration was significantly higher in the I/R group than in control group. These results were reversed with supplementation of L-arginine. Light microscopic examination revealed severe vascular congestion, edema, haemorrhage, and follicular degeneration in the ovary tissue. The extent of ovarian damage was much higher in the I/R group than in the I/R + L-arginine group. Treatment with L-arginine seems to have an ameliorating effect against oxidative stress in I/R injury in rat ovary. It considerably reduced the altered histological changes in the ovaries. Thus, it can be speculated that L-arginine might play a pivotal role as a potent therapeutic agent against ovarian torsion.
Effect of UV-B radiation on physiological and biochemical changes in a freshwater cyanobacterium, Scytonema hofmannii
Authors: Rupali Bhandari , Sharma Prabhat Kumar 
Published: July 2021

The effect of ultraviolet-B (UV-B) radiation and UV-B supplemented with low photosynthetically active radiation was investigated on photosynthesis, photosynthetic pigments, phycobilisomes, peroxidation of membrane lipids, fatty acids, and UV-B absorbing pigments in the freshwater cyanobacterium, Scytonema hofmannii. The present work aimed to study the UV-B radiation effect on photosynthesis and relate it to oxidative damage and protection provided by the UV-B absorbing compounds in a freshwater cyanobacterium. The results showed that photosynthesis and photosynthetic pigments were primarily affected by UV-B radiation, which seems to be the consequence of the generation of reactive oxygen species (ROS), as both ROS generation and oxidative damage to membrane lipids were observed, resulting in decreased survival of the test organisms. There was no significant change in the saturation and unsaturation level of fatty acids due to the treatments. We also suggest the role of mycosporine-like amino acids (MAAs) and scytonemin in protection against UV-B damage. Our results suggest that changes in photosynthesis, pigments, and peroxidation of membrane lipids may be a consequence of damage. In contrast, changes in fatty acids essentially resulted from the adaptation process against UV-B, and changes in UV-B absorbing compounds such as MAAs and scytonemin provided protection against the harmful effect of UV-B radiation.

Ego sentio, ergō sum!
Authors: Ashursky Emir 
Published: July 2021

In this article, the author examines several issues at once, of which at least three of the most fundamental can be distinguished. These are the things that are as old as the world, and each of them deserves a deep close analysis.
So, point one: where did the psyche come from and how did it then develop into a full-fledged human consciousness? The second discussed in detail problem is associated with the innate physiological asymmetry of the hemispheres (which, in turn, is capable of having a direct influence on both perinatal features and the entire subsequent mode of functioning of the central nervous system). And, finally, the third important block of questions raised here, by and large, goes back to enough heterodox idea that all living organisms (and with them, of course, man) are not divine creatures but simple biorobots.
Well, and besides, in his bold theoretical research, the author also makes another (for domestic philosophers and for humanities on the whole) daring attempt to penetrate into the most secret depths of spiritualized nature, with the mind's eye scanning the intracellular space and revealing thus the entire complex evolutionary mechanism of optimal program control in the system of higher nervous regulation. Moreover, on the course of the article, he managed to clearly substantiate either, that the so-called free will is pure fiction. After all, in practice, if it can exist at someone, then only, perhaps, among particular outstanding wonderworkers who, generally speaking, have a very, very distant relationship to you and me.
