Judicial legal positions in the context of conflicts related to the formation of the procedural status of persons against whom acts of criminal prosecution are actually implemented
Authors: Grachev Sergey
Published: January 2020

The article considers the grounds for the emergence of the procedural status of a suspect in a criminal case. The rights and obligations of the specified person, including the right to protection are analyzed. Subject to the requirements of the criminal procedure code of the Russian Federation, legal positions of the Constitutional Court of the Russian Federation and Plenum of the Supreme Court of the Russian Federation the conclusion about the necessity of legislative consolidation of the procedural status of the person whose rights and lawful interests are affected carried out in relation to proceedings for verification of a crime report in accordance with article 144 of the Criminal procedure code and equating it to the status of a suspect, since during the pre-investigation check he has the right to protection from the criminal prosecution actually carried out against him.
Methodology of jurisprudence in the context of the paradigm of scientific rationality
Authors: Kalinin Sergey
Published: January 2020

The article examines the methodological problems of jurisprudence, caused by a change in the paradigms of scientific rationality and corresponding to the level of conceptual structures. This level is characterized by problems of understanding the qualitative evolution of knowledge, as well as an appeal to a more abstract, rather than objective, level of understanding of reality. The named level, usually called philosophical, can be based on two genetically different axioms, namely philosophy, including the philosophy of the phenomenon being studied, as well as the philosophy and epistemology of science. At the same time, the difference in the initial axioms determines the difference in the final conclusions for an apparent terminological similarity. At present, philosophy in jurisprudence is mainly represented by postmodernism; the philosophy of law searches for the demarcation line between the philosophical-legal and theoretical-legal knowledge; the philosophy and epistemology of science that has developed within the framework of natural sciences is aimed at analyzing the foundations of models of scientific rationality, applicable, in particular, to the socio-humanitarian sphere. The legal distancing from classical rationality is represented by two main directions: the overcoming of classical rationality and appeal to the synergy and nonlinear dynamics. For the understanding of the law is enough selection of classical and post-classical type of rationality, while the conjugate with the state of knowledge of social management issues should be allocated classical, non-classical and post-nonclassical types of rationality. The postnonclassical paradigm (synergetics) allows us to consider the existence of unique (historical) open unstable nonlinear hierarchical dynamic complex, attractive self-developing subject systems, included in the sociocultural context, under external chaos and interacting with other subjects and subject systems. As a result, the

state and law conceptualized as dynamic organic selfregulating non-equilibrium systems, and in the subject field of law include the idea of philosophy, nonlinear dynamics and mathematical simulation of evolutionary and catastrophic processes that transforms the object and the subject of law and includes in it a number of qualitatively new methodological orientations.
About some features of theoretical understanding of search ideology of criminal proceedings
Authors: Konev Andrey
Published: January 2020

The article is devoted to the study of the features of the theoretical understanding of the investigative ideology of criminal proceedings. As a result of the research, the author came to the conclusion that there is an ideological paradox, which is that collective scientific efforts to strengthen the theoretical foundations of competition do not lead to tangible practical results. The development of legislation shows that the search ideology without any theoretical justification captures new horizons.

At the same time, the author believes that such successes of investigative ideology do not cancel the need for its thorough theoretical understanding, since the existence of a corresponding theory could significantly strengthen the existing practical successes of transferring criminal proceedings to the rails of a fair technology for establishing objective truth.

Authors: Mahmadzoda Neru
Published: January 2020

This article is devoted to one of the topical issues of law — the improvement of the criminal law on unlawful obtaining of a credit (article 264 of the Criminal code of the Republic of Tajikistan). The article considers such problems as the correct formation of the text of the law in order to avoid ambiguity in the understanding of socially significant norms. In addition, it is noted upon the presence of a gap in the knowledge of law enforcement officers of blanket norms and concepts, reflected in the norm on illegal obtaining of a credit.

It should be noted that the results of the study also demonstrate the relevance of issues in credit relations, including disproportion of fines in the sanctions of article 264 of the Criminal code of the Republic of Tajikistan to committed crimes and inclusion of such punishment as confiscation of property.

This article discusses problems in the breeding programs of the seedless grapes, the way of introducing of the biotechnology and gene technology skills to resolve its issues, and the advantages of molecular markers to select seedlessness among the hybrid progeny of grapes. Uzbekistan is famous for its seedless grapes, but on the other hand, the grape breeding is oriented on the conventional breeding method. In other words, seedless grapes have a recessive character, a male form is using only as a pollinator, and all these factors limit to create new seedless varieties and forms. Nowadays the word grape breeders, especially seedless grape breeders use advantages of the biotechnology and gene technology skills to resolve above listed issues. As a result, except for obtaining hybrid progeny by crossing between ♂seedless × seeded ♀ that was an unchangeable algorithm of the cross combination in the traditional grape breeding. But today, researchers argued that crossing between ♂seedless × seedless ♀ is also possible to obtain a hybrid progeny through “embryo rescue technique”. Thus introducing this novel breeding program directly to grape breeding of Uzbekistan leads to an increase the diversity of the new seedless grape varieties and also for increasing the export potential of the grape industry.

KEYWORDS: Seedless grape varieties, variety, cross combination, embryo culture, molecular markers, DNA.

Artykuł przedstawia autorską metodykę prognozowania procesów frontogenezy i frontolizy metodą Q-wektorów. Do jej realizacji wykorzystano zdjęcia satelitarne i dane numeryczne oraz zastosowano ideę przetwarzania równoległego. Metoda Q-wektorów służy do wyznaczania obszarów występowania prądów pionowych, określania ich kierunku i intensywności. Obszary Q-wektorów wskazują miejsca zbieżności i rozbieżności pola przepływu atmosfery, a tym samym wyznaczają rejony występowania prądów wstępujących i zstępujących. Obliczona na podstawie metody Q-wektorów funkcja frontogenetyczna wyznacza obszary frontogenezy i frontolizy. Przetwarzanie danych numerycznych wymaga zastosowania wydajnych systemów obliczeniowych. Zwiększanie wydajności współczesnych komputerów poprzez podwyższanie częstotliwości ich zegarów wewnętrznych w zasadzie dobiega końca. Właściwym kierunkiem rozwoju wydaje się być budowa komputerów o strukturach równoległych.

Published: January 2020

Chinese forest frog ovum oil is a medicinal food high in cholesterol. In the current study, we evaluated the relative efficiency of β-cyclodextrin, crosslinked β-cyclodextrin, and silica gel adsorption on cholesterol removal from Rana chensinensis ovum oil. Beta-cyclodextrin had the highest cholesterol reduction rate (60.84 ± 4.45%) among the three methods. We further evaluated the efficiency of cholesterol removal by beta-cyclodextrin in the presence of ethanol and higher (55°C) temperature. This resulted into cholesterol removal rate of as high as 76%. Interestingly, monounsaturated fatty acids increased from 4.96% to 29.12% after cholesterol removal. We conclude that beta-cyclodextrin is an excellent adsorbent for removing cholesterol from ovum oil.

Published: January 2020

Non-specific musculoskeletal pains (CNMP) are common problem with unknown etiology which has become a major concern because of their negative impact on health. The aim of the present study was to investigate the effect of vitamin D supplementation on pain scores, quality of life, self-rated health and sexual satisfaction among CNMP patients with vitamin D deficiency. In this clinical trial study, sixty-six patients (18–50 years in both sex) with CNMP and vitamin D deficiency were randomly assigned to consume 50000 IU vitamin D, once every week for 8 weeks in the intervention group or placebo in the control condition. Clinical examination, pain scores, quality of life (QoL), self-rated health and sexual satisfaction were measured at the beginning and at the end of study. Patients in the vitamin D group had a significant pain relief after 8 weeks compared to the placebo group (p = 0.04 vs. p = 0.42). Also, they had increased QoL scores and sexual satisfaction compared with placebo (p < 0.0001 and p = 0.01, respectively). We observed a significant effect on improvement of quality of life, sexual satisfaction and pain in patients with CNMP after administration of therapeutic doses of vitamin D. Such findings could be considered to implement informative interventional programs to control CNMP complications and develop practical policies to improve the diet quality among CNMP patients. Further studies are needed to determine whether vitamin D supplementation lead to significant modifications in CNMP complications with consideration of confounding factors in different population.

Published: January 2020

The objective of this study was to investigate the effect of protein oxidation on microbial, free amino acids (FAAs) and biogenic amines (BAs) in Chinese dry sausage during processing. Three different batches of Chinese dry sausages were examined: control batch, pro-oxidation batch and anti-oxidation batch. The experimental results revealed that anti-oxidation batch showed the lowest degree of protein oxidation compared with control batch, while the results of the pro-oxidation batch were just opposite. With the increasing protein oxidation, estimated by protein carbonyls and sulfhydryls, microbial content and free amino acid content increased, while BA content decreased. The protein carbonyls were positively correlated with total FAAs (P < 0.01) and total BA content (P < 0.05), while sulfhydryls content was negatively correlated with total FAA content (P < 0.01), total viable counts (P < 0.01), and total BA content (P < 0.01). In conclusion, reduced protein oxidation contributes to improved quality of Chinese dry sausage. This research provided a new strategy to improve the quality of meat product manufacture.

Published: January 2020

Type I collagen was described as a major allergen in fish. The purpose of this study was to screen and identify the linear IgE epitopes of type I collagen α1 and α2 subunits in rainbow trout. Five bioinformatics tools were used to predict the potential epitopes and the resultant epitopes were confirmed by LAD2 cells degranulation assay with sera from fish allergic patients. As the result, 10 peptides of α1 and α2 subunits were predicted, respectively, and these peptides were assembled by solid-phase synthesis. 14 epitopes were identified by LAD2 cells degranulation assay, among which, peptide 2, 5–7 were identified as linear epitope of α1 and peptide 11–20 were identified as linear epitope of α2. Moreover, for α1 and α2 subunits, the similarity of sequences was greater than 79%, suggesting the cross-reactivity of fish collagen. The findings of this study provided a strong support for further research of reduction of the collagen allergenicity.
Alternative to Nitrites as Antibacterial Agents Against Clostridium sporogenes
Authors: Zhi-Guo Zhang , Di Sun , Mei-Lin Wang
Published: January 2020

Microbial spoilage is one of the key challenges to food preservation and safety. Sodium nitrite, the commonly used antibacterial, is associated with the generation of nitroso compounds known to impose a number of health risks including cancer. In this article, we report a comparison of a number of food-grade antibacterials, not known to generate nitroso compounds, for the inhibition of Clostridium sporogenes. These include e-poly-lysine, potassium cinnamate, chitosan, and glycerol monolaurate. We examined the effects of these agents alone and in combination on cell morphology, cell wall, cell membrane permeability, and bacterial proteins of C. sporogenes. The results show that these agents primarily act to inhibit C. sporogenes growth during log phase. Further analysis with flow cytometry and scanning electron microscopy revealed that the compound can induce changes to the morphology of C. sporogenes cells and, more significantly, to the internal structure of the cells. Treatment of C. sporogenes with the compound inhibited the normal growth of bacterial cells by damaging their wall structure and increasing their wall permeability. The changing pattern of electric conductivity indicated that the compound destroyed cytoplasmic membranes and resulted in ion leakage. Sodium dodecyl sulfate polyacrylamide gel electrophoresis analysis of soluble proteins concluded that the compound can destroy bacterial cells by altering their proteins.

Published: January 2020

In order to take full advantage of the orange peel resource, polysaccharides were extracted from orange peel by hot buffer, chelating agent, dilute alkaline, concentrated alkaline, acid and enzyme extraction, respectively. The physicochemical properties and viscosity of the six polysaccharides were determined. The results showed that the six polysaccharides were mainly consisted of rhamnose, arabinose, galactose and glucose and traces of other monosaccharide. The six polysaccharides exhibited high total carbohydrate (89.74–98.08%), galacturonic acid content (GalA, 8.95–33.16%) and little proteins (<2%). Degree of methoxylation in polysaccharide obtained from orange peel by enzyme extraction and orange peel by acid extraction was higher than the others. They all showed good thermal stability under 84.5°C and non-Newtonian flow behaviors. Polysaccharide obtained from orange peel by hot buffer extraction has higher viscosity than the others at the 0.5% concentration. Polysaccharide obtained from orange peel by dilute alkali extraction appeared the highest viscosity with the increase of concentration, which may be due to the smallest hydrodynamic diameter and the highest rhamnose content.

Published: January 2020

To develop callus-derived tissue culture models for the production of secondary plant metabolites, conditions for callus induction from stems, needles and young buds of Torreya grandis were examined. The young buds were the best tissues for callus induction followed by stems and needles. While most needle and bud calluses turned brown and ceased growth by second subcultures, stem calluses exhibited rapid growth much longer. B5 medium supplemented with 2.0 mg/L naphthalene acetic acid, 0.5 mg/L kinetin, 20 g/L sucrose, and 8 g/L agar was the best medium for callus induction from stems when incubated at 25°C at 12 h light–dark cycle. These produced masses of friable calluses with a growth index of 4.7. However, callus subcultures maintained in darkness were generally of yellow-green color. There were some seasonal differences in callus induction with March being the best. The contents of paclitaxel in the calluses from needles, stems, and aril were 0.0212%, 0.0160%, and 0.0073%, respectively. However, the contents of baccatin III were 0.0034%, 0.0051%, and 0% in the calluses from needles, stems, and aril, respectively. In the suspension culture, B5 medium supplemented with 20 g/L sucrose on day 1 and 20 mg/L methyl jasmonate on day 7 showed improved cellular productivity resulting in the highest amount of paclitaxel (0.0257%) (2.842-fold higher than that of the untreated control) on day 14.

Authors: Wei Niu , Xiaxia Du , Qingyu Zhang , Chunsheng Kang
Published: January 2020

We evaluated the effects of bifidobacteria use after gastric cancer surgery on intestinal flora and serum expression of corticotropin-releasing factor (CRF). The patients treated with bifidobacteria were significantly less prone to complications such as reflux, vomiting, abdominal distention, diarrhea and constipation than the control group. After treatment, the numbers of Lactobacillus, Bifidobacterium, Bacteroides, Eubacterium and Peptococcus in the treatment group were significantly higher than in the control group and the numbers of Escherichia coli, Enterococcus and Clostridium were significantly lower. The serum CRF expression levels of treatment and control groups were (265.34 ± 31.78) and (286.25 ± 25.92) ng/mL respectively after treatment, which were both significantly lower than those before treatment, i.e. (310.54 ± 30.75) ng/mL and (309.65 ± 30.87) ng/mL (P < 0.05). Administering patients after gastric cancer surgery with bifidobacteria can effectively restore the intestinal flora imbalance and promote the reduction of serum CRF expression, thereby reducing the incidence of complications and benefiting the prognosis.

Published: January 2020

The main purpose of this study is to investigate the role of citrus leaf extract in carbon tetrachloride-induced hepatic injury and its potential molecular mechanism. Carbon tetrachloride was used to construct hepatic injury animal model. To this end, rats were randomly divided into 4 groups: control, carbon tetrachloride-treated, and two carbon tetrachloride + citrus leaf extract-treated groups. The results show that citrus leaf extract treatment significantly reversed the effects of carbon tetrachloride on the body weight changes and liver index. Besides, treatment with citrus leaf extract also reduced the levels of serum liver enzymes and oxidative stress in a dose-dependent manner. H&E staining and western blotting suggested that citrus leaf extract could repair liver histological damage by regulating AMPK and Nrf-2.

Under certain conditions, chitosans can react with different types of reducing sugars to form various final Maillard reaction products (MRPs). In this study, the optimal reaction conditions were selected, and three different final MRPs (xylose-MRPs, fructose-MRPs, glucose-MRPs) were analyzed. The structure of the three MRPs was analyzed using fluorescence, ultraviolet, and infrared spectroscopic methods, and then the antioxidant activities of the three MRPs were determined. The results showed that the three MRPs have similar structure and function, and the antioxidant activities between them have certain regularity. Antioxidant activities were ranked as follows: xylose-MRPs>fructose-MRPs>glucose-MRPs, and this order was inversely proportional to their reaction time, that is, shorter the reaction time, higher the antioxidant activity, while longer the reaction time, lower the antioxidant activity.

Essential oil of Herba pyrolae, a Chinese herbal medicine, has been suggested to exhibit anti-aging effects. To understand underlying mechanism, we have examined its effect on inhibition of two free radicals (2,2-diphenyl-1-picrylhydrazyl and 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid) and tyrosinase. The half maximal inhibitory concentration (IC50) of the essential oil was 0.1045 mg/mL for DPPH, while that for ABTS was 0.3961 mg/mL. In addition, the essential oil inhibited both monophenolase and diphenolase activities of tyrosinase. Further examination of the tyrosinase inhibition mechanism and kinetics showed that the diphenolase activity inhibition by H. pyrolae essential oil was a non-competitive reversible process. These data suggest possible mechanism(s) underlying anti-aging effects of H. pyrolae essential oil.
