PSYCHROTROPHIC MICROORGANISMS OF THE FAR EAST SOILS

Posted in 2019, BIOLOGY, Issue № 12(90) December 2019, БИОЛОГИЧЕСКИЕ НАУКИ | 0 comments

70 psychrotrophic isolates of microorganisms were isolated from the soils of the Far Eastern region of Russia (Sakhalin, Yakutia, the Jewish Autonomous Region, Amur Region, Magadan, Iturup Island, Kamchatka). It was established that three isolates taken from the soils of l. Iturup and Yakutia have all three activities as a result of the screening of these isolated isolates for the presence of enzymatic activity (amylase, protease, and lipase). Two of the three activities showed 16 isolates. Thus, 21 isolates, which were introduced into the collection for further study, are the most promising ones.

MORPHOLOGICAL AND GENETIC FEATURES OF SOILS IN URUP ISLAND

Posted in 2019, BIOLOGY, Issue № 12(90) December 2019, БИОЛОГИЧЕСКИЕ НАУКИ | 0 comments

The paper presents the results of diagnostics and determination of the classification position of soils, which are located in the central part of Urup Island using the profile-genetic approach. The studied soils were formed on the coastal and slope areas of the island. The morphological, physical, and physicochemical characteristics of the studied soil profiles are provided as well. It was revealed that soils on a steep slope are polygenetic formations, but do not belong to layered soil types. The soils are light in terms of particle size distribution. A decrease was found in the content in depth along the profile of silicon oxide with a simultaneous increase of 1.5-2 times the number of one and a half oxides. The soils developed on the stretch of the sea terrace are layered. It was suggested that the physicochemical properties are influenced not only by plant associations, a low amount of organic carbon, but also largely by proximity to the slightly alkaline waters of the Sea of Okhotsk.

LONG-RANGE TEMPORAL CORRELATIONS IN THE AMPLITUDE OF ALPHA OSCILLATIONS PREDICT WORKING MEMORY PERFORMANCE

Posted in 2019, BIOLOGY, Issue № 12(90) December 2019 | 0 comments

The ability to successfully perform a task is supported by inhibition of irrelevant information. Evidence showed that alpha oscillations (8-15 Hz) play a key role in protecting relevant information from the appearance of distractors during a working memory (WM) task. Here, we investigated how the temporal dynamics of alpha rhythm at rest predict the WM performance in a modified delay-match Sternberg paradigm.
We hypothesize that the behavioral performance can be predicted by the dynamics of oscillatory activity at rest. To this end we used Long-Range Temporal Correlation (LRTC), a novel and reliable approach to quantify the balance between excitation and inhibition in neuronal networks.
Subjects were recorded with scalp EEG during rest before undergoing the WM task. LRTC were measured at rest in the alpha band in order to predict the inter-individual differences in the WM performance.
We found that LRTC at rest over frontal cortex were predictive of the level of accuracy in the WM task across individuals. Importantly, no effect was visible when considering spectral EEG power at rest.
While frontal cortex is known to be involved in suppressing distractor interference, we show here that the ability to switch between attention and sensory suppression can be measured already in the neural temporal dynamic as a feature of the single individual.

FUNCTIONS OF POSTPYROGENOUS COAL IN SOILS OF BORAL FORESTS OF FAR EAST

Posted in 2019, BIOLOGY, Issue № 12(90) December 2019, БИОЛОГИЧЕСКИЕ НАУКИ | 0 comments

Boreal forests are the most significant carbon sink among ground ecosystems. Forest fires occur annually on millions of hectares of the boreal zone. Millions of tons of carbon fixed previously by forests are lost in the form of carbon dioxide during combustion, as well as gigatons of post-pyrogenic coal. Being the most inert and long-term combustion product, coal has been attracting the attention of scientists since the mid-20th century, but its ecosystem function has not yet been fully understood. The goal of the study is to establish the effect of coal on soil properties, renewal of vegetation, and decomposition of organic matter in the boreal forests of the Far East. The studies were conducted in the northern part of the Amur Region in the larch forests of the foothills of the Tukuringra ridge. A positive correlation was established between the coal content in the soil and soil acidity (рНH2O) p <0.05, soil moisture, and mobile phosphorus content. Coal has a positive effect on pine regeneration. The coal content in the soil after the fire had no correlation with the content of ammonium forms of nitrogen (NH4+) and the number of larch seedlings (p = 0.664 and 0.5135). Coal accelerates the late stages of decomposition of thin larch roots. The background concentration of coal did not affect the decomposition of the roots, while the double average and maximum concentrations had a similar effect of accelerating decomposition. The research results show that under the conditions of postpyrogenic forests of the Russian Far East, coal performs a significant ecosystem function by accelerating the accumulation of stable forms of carbon in soils and the renewal of coniferous primary forests.

INFLUENCE OF 1-HYDROXY-1.1-ETHYLIDE DIPHOSPHONIC ACID ON THE BEHAVIOR OF RAT FEMALES IN “OPEN FIELD” AND “ELIMINATED PLUS MAZE” TESTS

Posted in 2019, BIOLOGY, Issue № 10(88) October 2019, БИОЛОГИЧЕСКИЕ НАУКИ | 0 comments

The article presents data on the study of the effect of 1-hydroxy-1.1-ethylidene diphosphonic acid in a wide range of doses (from 5 to 200 mg/kg) on the behavior of female rats in the open field and elevated plus maze tests. The experiments were performed on 60 female Wistar rats. The results show that studied acid in the open field test at a dose of 150 mg/kg inhibits the locomotor activity, search and research behavior of the test animals, which indicates a sedative and anxiogenic effect of this dose of acid. These effects were reflected in a significant decrease relative to the control of the total distance by 49.06% (p≤0.001, n = 10) and the research activity of minks by 51.85% (p≤0.05, n=10). The “elevated plus maze” test showed a weak anxiogenic effect of 1-hydroxy-1.1-ethylidene diphosphonic acid at a dose of 150 mg/kg, which manifested itself only in a significant decrease relative to the control of the exit time of rats to the centre of the labyrinth by 79.35% (p≤0.05, n=10).

INDICATORS OF CARDIORESPIRATORY SYSTEM OF RATS UNDER THE EFFECT OF BIS (2-PYRIDYL) -3- (1,2,4-TRIAZOLYL) PROPANE

Posted in 2019, BIOLOGY, Issue № 10(88) October 2019, БИОЛОГИЧЕСКИЕ НАУКИ | 0 comments

The article presents the results of the study of the effect of bis (2-pyridyl-1,2,4-triazolyl-3) propane in doses of 5, 50, 100, 150, and 200 mg/ kg on the cardiorespiratory system of male and female rats. The experiments were performed on 84 Wistar rats (42 males and 42 females). It was shown that bis (2-pyridyl-1,2,4-triazolyl-3) propane (BTP) at a dose of 50 mg/kg has the most pronounced effect on the regulation of microcirculation, which was manifested in the increase of the activity of all factors regulating microcirculation. At this dose, it exhibits a hypotensive, vaso-relaxing and negative chronotropic effect. At a dose of 100 mg/kg, BTP exhibits hypertensive, vaso-constrictive, and positive chronotropic effects. It is likely that the presence of 1,2,4-triazolyl in the BTP molecule is crucial for the emergence of cardio and vaso-tropic properties.
