REGULARITIES OF HYDROGEN GENERATION BY HYDROLYSIS OF SODIUM BOROHYDRIDE ON IMMOBILIZED PLATINUM CATALYSTS
Authors: Pirskyy Yuriy , Manilevich Fedor , Kutsyi Andrii
Published: May 2022

Sodium borohydride hydrolysisis one of the most productive hydrogengeneration methods, which can be used, inparticular, to power fuel cells with a hydrogenanode. In alkaline solutions, the interaction of NaBH4 with water practically does not occur, which makes it possible to store such solutions for a longtime. However, in the presence of catalysts, the borohydride hydrolysis reaction actively proceeds at room temperature with the formation of hydrogenand sodium metaborate. More than 300 homogeneous and heterogeneous catalysts for the hydrolysis of sodium borohydride are known, among which the most active metal catalysts are nanodispersed rhodium, ruthenium, and platinum immobilized on various substrates. The activity of such catalysts depends on the conditions of the reduction and immobilization of metals, the nature of used precursors, the amount of active phase of the catalyst, and the type of substrate. In this work, platinum catalysts immobilized on several substrates are developed, and the regularities of hydrolysis of sodium borohydride in alkaline solution when using such catalysts in flowing flat and cylindrical reactors are investigated. Using various methods, platinum was deposited on carbon black and carbon cloth, onactivated granular carbon, on titanium crumb, and on synthetic cordierite of honey combstructure with surface, previously modified by alumina. It is shown that nanodisperse platinum catalysts immobilized on carbon black and carbon cloth and especially on synthetic cordierite of cellular structure with surface previously modified by Al2O3 layer are active and reliable. The average rate of hydrogen evolution during hydrolysis of NaBH4 on such catalysts increases with increasing flow rate of its solution through the reactor, but the degree of conversion of sodium borohydride decreases due to the reduced duration of contact of the solution with the catalyst. Nanodisperse platinum catalysts on surface-modified cordierite provide a highandstable rate of hydrogengeneration with moderate heating of NaBH4 solution (60±5°C). The use of hydrogen generators with such catalysts in combination with fuel cell batteries is promising for the creation of autonomous powers ources.

Semantic prosody of Slovene adverb–verb collocations: introducing the top-down approach
Authors: Jurko Primož
Published: May 2022

This paper presents a corpus-driven Sinclairian analysis of five high-frequency Slovene verbs covering the lexical paradigm ‘to express orally’ in combination with their premodifying adverbs of manner. One of the main goals of the paper is to establish how frequent the phenomenon of semantic prosody actually is among high-frequency lexical items (here, adv-v pairs). A methodology aiming to provide an answer to this question has been proposed featuring the top-down approach (i.e., in order of decreasing frequency of occurrence). It involves setting up the widest possible parameters of searching for so-called ‘extended units of meaning’ and their semantic prosody amongst the most frequent lexical patterns in a language. A total of twenty-six adv-v pairs have been examined. Results indicate a strong correlation between the frequency of multi-word lexical items and their tendency to develop semantic prosodies: high-frequency collocations are thus more likely to have semantic prosodies compared to their lower-frequency counterparts. Overall, results also corroborate the trend of semantic prosody to be found with mainly negative meanings and to a lesser extent in neutral meanings, while no positive semantic prosody has been determined in this study.

Authors: Kuznetsova E. K. , Kudrevich Y. V. , Ziganshin O. R. , Dolgushin I. I.
Published: May 2022

The use of lasers in medical cosmetology today is widespread. The effects of laser techniques are pronounced and persistent. It is known that skin microcirculation increases after the procedures, renewal of keratinocytes and fbroblasts is stimulated, but there is little information about the molecular basis of the action of ablative lasers, about the mechanisms underlying the formation of new tissues (various types of collagens, laminin, vessels of the microvasculature).

Purpose of the study. Formation of a detailed understanding of the mechanisms underlying the regenerative processes of the skin after ablative laser exposure.

Results. After ablative laser exposure, the amount of interleukin-1α signifcantly increases, which leads to stimulation of the formation of type I and III collagens, laminin. There is an increase in vascular, fbroblast growth factor, which also helps to stimulate the proliferation of fbroblasts, increase its blood supply.

Conclusions. Based on the data obtained, it can be concluded that fractional photothermolysis improves the elastic properties of the skin, enhances skin trophism and activates the metabolism of the skin. The prolongation of the effects of a single procedure is due to the activation and stimulation of the skin’s own regenerative resources, which contributes to an increase in its own fbroblasts, collagens, vessels of the microvasculature, cells of the epidermis and dermis.

The cytological examination is simple to perform and is widely used for the initial examination of patients with skin tumors, both non-pigmented and pigmented. This article discusses in detail the history of the use of cytological examination, technique, diagnostic criteria for basal cell skin cancer. Particular attention is paid to the objective diffculties in the application of the method, the rather high specifcity of cytological examination in the diagnosis of basal cell skin cancer is illustrated.
Candidiasis of large folds and secondary pyoderma: Clinical case report
Authors: Yakovlev A. B.
Published: May 2022

Candidiasis is a mycosis of the skin and mucous membranes caused by a conditionally pathogenic fungus, and the lesion of skin folds is one of the most widespread forms of this mycosis. A feature of the course of the skin process in this form, in the absence of adequate therapy and the presence of exogenous or endogenous predisposing factors, is the inevitable addition of secondary bacterial infection and the development of pyoderma. The article presents a clinical case of candidiasis of large folds complicated by secondary pyoderma, discusses the principles of external and systemic therapy of two related diseases.
Food retailer price convergence: the case of Tijuana, Mexico
Authors: Díaz Eduardo R
Published: May 2022

The objective of this study is to compare prices across ten food categories sold by four large food retail chains in Tijuana, Baja California, Mexico. The data was collected through mystery shoppers across a seven-month period. The analysis consisted of descriptive statistics and analyses of variance (ANOVA). The results suggest that the retailers in the study apply similar prices across ten food categories. This is one of the few studies conducted in the region to address food price convergence in the retail sector. The conclusion is that price convergence takes places among large retail chains in Tijuana. The main limitation of the study is the geographic focus. The implications are that retailers find themselves struggling to differentiate based on price, and end up making unsupported claims around lowest-price value propositions. Future studies can argue whether price convergence limits consumer choices or keeps prices in check.
Desastres y covid-19: dos modelos para reducir el riesgo en México
Authors: Rodríguez Esteves Juan Manuel
Published: May 2022

The objective is to analyze the scope of the National Civil Protection System (SINAPROC) and the National Health System (SNS), and its relationship to the attention of the Covid-19 pandemic. The study is within the approach to disaster risk, considering how the concretion of a threat, exposition and vulnerability can affect society. The first part makes a diagnosis of the impact of disasters associated with natural phenomena, as well as the evolution of the COVID-19. Subsequently, the legal framework underpinning both systems is discussed, considering their structure and components for identifying possible mechanisms of collaboration. Among the conclusions is that, despite being two vertical models of intervention, the legislation incorporates both health and disaster risk, which could complement each other. At the end of the pandemic, the strategy to strengthen the health risk management model should be evaluated from the disaster risk approach.

The classical Box-Pierce and Ljung-Box tests for auto-correlation of residuals possess severe deviations from nominal type I error rates. Previous studies have attempted to address this issue by either revising existing tests or designing new techniques. The Adjusted Box-Pierce achieves the best results with respect to attaining type I error rates closer to nominal values. This research paper proposes a further correction to the adjusted Box-Pierce test that possesses near perfect type I error rates. The approach is based on an inflation of the rejection region for all sample sizes and lags calculated via a linear model applied to simulated data that encompasses a large range of data scenarios. Our results show that the new approach possesses the best type I error rates of all goodness-of-fit time series statistics.

The impact of graphene oxide on hepatic functional cells represents a crucial evaluation step for its potential application in nanomedicine. Primary human hepatocytes are the gold standard for studying drug toxicity and metabolism; however, current technical limitations may slow down the large-scale diffusion of this cellular tool for in vitro investigations. To assess the potential hepatotoxicity of graphene oxide, we propose an alternative cell model, the second-generation upcyte® hepatocytes, which show metabolic and functional profiles akin to primary human hepatocytes. Cells were acutely exposed to sub-lethal concentrations of graphene oxide (≤80 μg/ml) for 24 h and stress-related cell responses (such as apoptosis, oxidative stress, and inflammatory response) were evaluated, along with a broad investigation of graphene oxide impact on specialized hepatic functions. Results show a mild activation of early apoptosis but not oxidative stress or inflammatory response in our cell model. Notably, while graphene oxide clearly impacted phase-I drug-metabolism enzymes (e.g., CYP3A4, CYP2C9) through the inhibition of gene expression and metabolic activity, conversely, no effect was observed for phase-II enzyme GST and phase-III efflux transporter ABCG2. The GO-induced impairment of CYP3A4 occurs concomitantly with the activation of an early acute-phase response, characterized by altered levels of gene expression and protein production of relevant acute-phase proteins (i.e., CRP, Albumin, TFR, TTR). These data suggest that graphene oxide induces an acute phase response, which is in line with recent in vivo findings. In conclusion, upcyte® hepatocytes appear a reliable in vitro model for assessing nanomaterial-induced hepatotoxicity, specifically showing that sub-lethal doses of graphene oxide have a negative impact on the specialized hepatic functions of these cells. The impairment of the cytochrome P450 system, along with the activation of an acute-phase response, may suggest potential detrimental consequences for human health, as altered detoxification from xenobiotics and drugs.

Mechanical stretch is one type of common physiological activities such as during heart beating, lung breathing, blood flow through the vessels, and physical exercise. The mechanical stimulations regulate cellular functions and maintain body homeostasis. It still remains to further characterize the mechanical-biomechanical coupling mechanism. Here we applied fluorescence resonance energy transfer (FRET) technology to visualize ERK activity in airway smooth muscle (ASM) cells under cyclic stretch stimulation in airway smooth muscle (ASM) cells, and studied the mechanosensing pathway. FRET measurements showed apparent ERK activation by mechanical stretch, which was abolished by ERK inhibitor PD98059 pretreatment. Inhibition of extracellular Ca2+influx reduced ERK activation, and selective inhibition of inositol 1,4,5-trisphosphate receptor (IP3R) Ca2+channel or SERCA Ca2+pump on endoplasmic reticulum (ER) blocked the activation. Chemical inhibition of the L-type or store-operated Ca2+channels on plasma membrane, or inhibition of integrin β1 with siRNA had little effect on ERK activation. Disruption of actin cytoskeleton but not microtubule one inhibited the stretch-induced ERK activation. Furthermore, the ER IP3R-dependent ERK activation was not dependent on phospholipase C-IP3signal, indicating possibly more mechanical mechanism for IP3R activation. It is concluded from our study that the mechanical stretch activated intracellular ERK signal in ASM cells through membrane Ca2+channels mechanosensation but not integrin β1, which was mediated by actin cytoskeleton.
