Abstract:

This paper explores some basic representational and implementation issues arising from the premise that cortical circuits operate on probability density functions to reason about analog quantities. Some insight is provided into why neurobiological systems can appear messy, while at the same time provide a rich and robust computational environment.

Abstract:

A definition of biological essential elements was proposed. Their origin and function in human body were discussed. An excellent strain Sl of Tetrahymena, a kind of ciliates, has been used in this study to observe both stimulation or nutritious and toxic inhibition effects of elements located in s block, p block, d block, and f block in the periodic table, some regularity between the biological effects of these elements and their positions in the periodic table has been obtained. It is shown that a “spectrum of biological element equilibrium”, which exists in organism, can be exhibited in the periodic table designed in the three-dimensional space, if the abundance of biological elements or/and their bioavailability is used as the third z axis, a vertical line to the plane of the periodic table, and then the biological element spectrum shows that the exchanges of matter and energy between organism and surface environment of the earth have reached the dynamic equilibrium state. It seems that not only physical and chemical properties of different elements and compounds, but also their biological properties to a certain extent can be shown in the developed periodic table.

Abstract:

Mamaq by the ancestors of the Sasak people was an activity of chewing betel nut, lime, betel leaf, and tobacco, and ending with shrinkage. Betel leaves contain glycosides, steroids, triterpenoids, flavonoids, tannins, and anthraquinones. These compounds contain antimicrobial activity that can fight Staphylococcus aureus, Escherichia coli, and Candida albicans fungi. Meanwhile, whiting is a strong base because it has a pH of 11-12.5. This is because in the mouth there is saliva which can maintain a pH of around 6.8. Saliva contains phosphate buffer solutions H2PO4- and HPO42-. And gambir contains a component in the form of catechins which function as antioxidants and antibacterials. The purpose of this research is to study philosophical values, especially epistemology, which investigates the origin, and composition of methods and knowledge related to mamaq philosophy and natural science concepts, especially chemistry, and compounds, and what reactions occur in the mamaq process that has not been revealed. The study uses the library method. From the results of thestudy, it was concluded that in addition to the philosophy in the ingredients for mamaq it can also be described the chemical compounds contained in the ingredients for mamaq, starting from whiting, green betel leaf, gambier, and areca nut.

Abstract:

One of the goals of soft robotics is to implement intelligent functions capable of processing complex information in soft materials. This is a noble goal, and we already have a familiar example, albeit not an artificial one, in a living organism. We believe that the intelligent biological elements acquired through the evolutionary process, which do not require an electricity supply or CPU, can be used for soft robotics. In this letter, we introduce three biological elements: proteins, squid, and nematodes, which show temporal or special patterns. We then discuss an attempt to apply them to soft robotics.

Abstract:

The work is devoted to the development of technology for enriching artemia with biologically active substances. The development of technology for enriching artemia with biologically active substances is important as an opportunity to obtain starter feeds for aquaculture with the desired properties. High content of high-grade protein, vitamins, amino acids, fatty acids, biogenic elements is of great importance. During artificial cultivation of artemia in a closed cycle in the conditions of aquaculture, there is a problem of sufficient accumulation of substances in its body that provide high nutritional and biological value. To solve this problem, we have developed a technology for enriching artemia with biologically active substances at the nauplium stage. The enrichment of artemia with vitamins, amino acids, probiotics, adaptogens, essential lipids allows us to create a new generation of bio-feeds containing a living symbiotic microbiota and ingredients capable of forming balanced complex of functional nutrition for fish. The aim of the study was to evaluate the biological and energy value, the content of proteins, fats, carbohydrates, moisture, ash, micro- and macroelements, heavy metals in artemia at different stages of ontogenesis against the background of its enrichment with a complex of biologically active substances. Intact and enriched cysts, intact and enriched decapsulated artemia eggs, enriched artemia nauplii were analyzed. It was found that against the background of enrichment with biologically active substances, the indicators of metabolic energy increased, the mass fraction of crude protein, the mass fraction of fat and the content of minerals and biogenic elements increased.

Abstract:

The geosphere of primitive Earth was the source of life’s essential building blocks, and the geochemical interactions among chemical elements can inform the origins of biological roles of each element. Minerals provide a record of the fundamental properties that each chemical element contributes to crustal composition, evolution, and subsequent biological utilization. In this study, we investigate correlations between the mineral species and bulk crustal composition of each chemical element. There are statistically significant correlations between the number of elements that each element forms minerals with (#-mineral-elements) and the log of the number of mineral species that each element occurs in, and between #-mineral-elements and the log of the number of mineral localities of that element. There is a lesser correlation between the log of the crustal percentage of each element and #-mineral-elements. In the crustal percentage vs. #-mineral-elements plot, positive outliers have either important biological roles (S, Cu) or toxic biological impacts (Pb, As), while negative outliers have no biological importance (Sc, Ga, Br, Yb). In particular, S is an important bridge element between organic (e.g., amino acids) and inorganic (metal cofactors) biological components. While C and N rarely form minerals together, the two elements commonly form minerals with H, which coincides with the role of H as an electron donor/carrier in biological nitrogen and carbon fixation. Both abundant crustal percentage vs. #-mineral-elements insiders (elements that follow the correlation) and less abundant outsiders (positive outliers from the correlation) have important biological functions as essential structural elements and catalytic cofactors.

AbstractThe extremely high sensitivity of biological systems provides the key to understanding homœopathic ‘effects’. According to the classical analogon of a pendulum, the ‘coherent state’ in quantum physics are able to explain the simile principle as well as the potency rule as interrelated phenomena. The basic effect is always delocalization of the energy to such an extent that the physical proof gets more and more complicated the higher the efficacy becomes.

Full text

Abstract:

Alus, the short interspersed repeated sequences (SINEs), are retrotransposons that litter the human genomes and have long been considered junk DNA. However, recent findings that these mobile elements are transcribed, both as distinct RNA polymerase III transcripts and as a part of RNA polymerase II transcripts, suggest biological functions and refute the notion thatAlusare biologically unimportant. Indeed,AluRNAs have been shown to control mRNA processing at several levels, to have complex regulatory functions such as transcriptional repression and modulating alternative splicing and to cause a host of human genetic diseases.AluRNAs embedded in Pol II transcripts can promote evolution and proteome diversity, which further indicates that these mobile retroelements are in fact genomic gems rather than genomic junks.

Abstract:

AbstractPsoriasis is a chronic, autoimmune, and complex genetic disorder that affects 23% of the European population. The symptoms of Psoriatic skin are inflammation, raised and scaly lesions. microRNA, which is short, nonprotein-coding, regulatory RNAs, plays critical roles in psoriasis. microRNA participates in nearly all biological processes, such as cell differentiation, development and metabolism. Recent researches reveal that multitudinous novel microRNAs have been identified in skin. Some of these substantial novel microRNAs play as a class of posttranscriptional gene regulator in skin disease, such as psoriasis. In order to insight into microRNAs biological functions and verify microRNAs biomarker, we review diverse references about characterization, profiling and subtype of microRNAs. Here we will share our opinions about how and which microRNAs are as regulatory in psoriasis.

Abstract:

Objectives: Anthropogenic exposures to rare earth elements are poorly known and there is limited information on their toxicity and ecotoxicity. At the same time, world production of rare earth elements has doubled every 15 years over the last half-century, and high environmental concentrations of gadolinium and lanthanum have already been found. The current review aims to give some estimates of overall exposures and an initial in-depth appraisal of thresholds for effects on agricultural soil. The results are envisaged to be used in initial assessments of agricultural soil where the natural concentrations have been anthropogenically enhanced. Methods: An extensive review has been made of available scientific literature. Criteria have been established for the selection and analysis of eligible research. For instance, only effects on soils with vegetation have been included in the assessment of biological effects. A species sensitivity distribution based on 25% inhibition of organism functions has been used to establish thresholds for effects on soil organisms. Results: Around the year 2000, mean anthropogenic contributions of lanthanides in European soil regions were at most a few per cent of the total soil content. Since then, they should have increased considerably. The proposed hypothetical threshold for agricultural soils is 1125 mg total rare earth element per kg of soil. This threshold is about 8 times the natural soil concentration. Conclusions: If this result holds up to scrutiny, it implies that general anthropogenic pollution by rare earth elements will not be a threat to agricultural sustainability for the coming generation. A preliminary assessment suggests that this threshold would also protect humans from adverse effects due to secondary exposure.

Abstract:

The richness of civilization is the soil which 99% of it produces food. There is more than 95% of the gene pool of living matter in the soil of planet. In modern conditions, there is a problem of rational use of soil as place for natural formations (edafotops) which are the most important components of biogeocenosis. The relevance of this work is that the soil as nutrient in the biosphere performs a unique function. The most important parameter is the fertility of the soil, which determines the basic properties of terrestrial ecosystems: efficient production and stability. Estimation of the main factors of fertilityed edafotop is a mandatory element of environmental monitoring. The purpose of this work is to study the dynamics of acidity and assessment of humus content in soil with sand and character changes on the number of microorganisms of major ecological-trophic groups and quantitative analysis of microalgae with typical chernozem processing and No-Till. Scientific novelty of results. For the first time the complex estimation of features humus formation in typical horizons layer was conducted and the dependence population of the complex microbial edafotop farm was installed on the territory farming systems of Semenivka district of Poltava region. For research were selected 17 soil samples in Semenivka district (Poltava region). The soil samples were selected in the localities which use standardized methods and techniques. The objects of study are samples chernozem typical from edafotop with different processing technology, in particular after making defekat sugar production, selected on the territory of the farm agrocenosis. Subject of research is dynamics of humus, microbiota and algae in soils that are traditionally handled by biotechnology and No-Till, and the impact a defekat of sugar production on the soil acidity. As a result of research settled the following tasks: 1) it was selected the samples of chernozem with varying technology soil processing; 2) it was estimated humus content by Tyurin (titrimetric) and acidity of soil samples by potentiometry; 3) it was investigated the feasibility of using a defekate after sugar production as fertilizer; 4) it was found the number of complex microbial studied soils; 5) it was set the factors in the formation of complex microbial soil; 6) it was set of environmental measures aimed at restoring of soil fertility. Soil samples were prepared for analysis by standard procedure. During the research was used a method of potentiometry to determine pH (degree of acidity of the soil solution). The concentration of humus titrimetric determined by using of chromium mixture and Mohr's salt (I. V. Tyurin method). Preliminary preparation of soil for microbiological analysis was performed by dispersing. For quantifying soil microorganisms was used the method of planting soil slurry into solid peptone-agarnutrient media and Zvyagintsev's scale. Statistical analysis of the results of research was carried out using MS Excel. The practical significance of the results is the scientific substantiation of ecological and economic profitability of introducing technology No-Till in Ukraine. This agrotechnology will preserve and restore the fertile layer of soil (improving its chemical, physical and biological properties, increasing content of organic matter in the soil), reduce or eliminate erosion of soil (no need to spend extra money to solve this problem), accumulate and retain the moisture in the soil, which in turn will reduce dependence the crop on climatic conditions and increase crop yields. It Is established that the use of No-Till system increased content humus, increased the number of microorganisms and soil microalgae, which can significantly affect the fertility of chernozem.
