In this review, the relevance of plants belonging to the Pedicularis L. genus was explored from different points of view. Particular emphasys was given especially to the phytochemistry and the ethnopharmacology of the genus since several classes of natural compounds have been evidenced within it and several Pedicularis species are well known to be employed in the traditional medicine of many Asian countries. Nevertheless, some important conclusions on the chemotaxonomic and chemosystematic aspects of the genus were also provided for the first time. This work represents the first total comprehensive review on the genus Pedicularis.

Kaempferia galanga included in the Zingiberaceae family is one of the potential medicinal plants with aromatic rhizome. In traditional medicine in Asian countries, this plant is widely used by local practitioners. This plant is widely cultivated in most Southeast Asian countries such as Cambodia, Vietnam, Malaysia, Thailand, and Indonesia. Ethyl-para-methoxycinnamate and ethyl-cinnamate are found as the main compounds in hexane, dichloromethane, and methanol extracts of K. galanga. This plant is traditionally used as an expectorant, stimulant, diuretic, carminative, and antipyretic remedy. In addition, K. galanga is used for treatment of diabetes, hypertension, cough, asthma, joint fractures, rheumatism, urticaria, vertigo, and intestinal injuries. Therefore, this study aimed to give a sneak peek view on galangal’s ethnobotany, toxicology, pharmacology, and phytochemistry.

Asian countries are reckoned for their vast plant-rich regions with a long history of traditional medicine that spans approximately 6,500 years. Asian people inherit knowledge from their ancestors about the use of the surrounding plants to treat many infirmities and diseases, including stress-related disorders such as anxiety and depression. As such, this review provides an ethnopharmacological and phytochemical overview of Asian plants with high antistress potential. This review serves as a baseline for the discovery of new and potent antidepressants. Articles from 2007 to 2020 were reviewed extensively using Google Scholar and Scopus search engines based on the following keywords: ‘antidepressant AND Asia AND plants’, ‘anxiolytic AND Asia AND plants’, as well as ‘antistress AND Asia AND plants’. In total, 71 Asian plants were documented. Most of the plants were reported from India (36%) and followed by China (31%). Other countries, including Japan, Bangladesh, Thailand, Pakistan, Korea, Taiwan and Algeria, have published several reports regarding local plants with antidepression potential. As a result, 15 pure compounds isolated from these plants displayed antidepressive potential.

Abstract Background Enterocytozoon hepatopenaei (EHP) is an enteric pathogen that affects Penaeus vannamei and Penaeus monodon shrimp in many SE Asian countries. In the western hemisphere, EHP was reported for the first time in 2016 in farmed P. vannamei in Venezuela. Anecdotal evidence suggests that EHP is more prevalent in grow-out ponds where the salinity is high (> 15 parts per thousand (ppt)) compared to grow-out ponds with low salinities (< 5 ppt). Considering that P. vannamei is an euryhaline species, we were interested in knowing if EHP can propagate in P. vannamei in low salinities. Results In this study, we described an experimental infection using fecal strings as a source inoculum. Specific Pathogen Free (SPF) P. vannamei were maintained at three different salinities (2 ppt, 15 ppt, and 30 ppt) while continuously challenged using feces from known EHP-infected P. vannamei over a period of 3 weeks. The fecal strings, used as a source of EHP inocula in the challenges, was sufficient to elicit an infection in shrimp maintained at the three salinities. The infectivity of EHP in shrimp reared at 2 ppt, 15 ppt, and 30 ppt salinities was confirmed by PCR and histopathology. The prevalence and the severity of the EHP infection was higher at 30 ppt than at 2 ppt and 15 ppt. Conclusion The data suggests that fecal strings are a reliable source of EHP inoculum to conduct experimental challenges via the fecal-oral route. An EHP infection can occur at a salinity as low as 2 ppt, however, the prevalence and the severity of the EHP infection is higher at a salinity of 30 ppt.

Euphorbia hirta Linn, a representative of the Euphorbiaceae family, is a widespread annual herb found in wastelands in humid conditions. The plant is high in phytochemicals such as tannin, quercetin, and phytosterol, however there are few phytopharmacological investigations on it. Plant components are normally employed in traditional medicine to treat respiratory problems, gastrointestinal issues, wound healing, and other ailments. The steroid of E. hirta was found to have CNS depressive and muscle relaxant effects, as well as a sub-maximal anti-stress and anxiolytic impact.

Diazocarbonyl compounds have found numerous applications in many areas of chemistry. Among the most developed fields of diazo chemistry is the preparation of azoles from diazo compounds. This approach represents a useful alternative to more conventional methods of the synthesis of azoles. A comprehensive review on the preparation of various azoles (oxazoles, thiazoles, imidazoles, pyrazoles, triazoles, and tetrazoles) from diazocarbonyl and related compounds is presented for the first time along with discussion of advantages and disadvantages of «diazo» approaches to azoles.

The article analyzes the concept of mathematical literacy. The formation of mathematical literacy among members of modern society is a fundamental basis for the formation of functional literacy. Currently, there is no single approach to the interpretation of the concept of "mathematical literacy", the article provides several different approaches to the definition. Based on the analysis of the points of view of different scientists, the authors of the article highlight the main components of the concept of "mathematical literacy". These include: literacy of mathematical speech; possession of mathematical concepts; the ability to correctly formulate definitions and statements; the ability to apply mathematics to research. The paper provides a characteristic of the listed components of mathematical literacy. In addition, in this work, for the first time, an attempt was made to formulate the levels of mathematical literacy – speech, terminological, critical and operational. The article presents the results of testing students in pedagogic areas of training of two universities – Kostroma State University and Yaroslavl State Pedagogic University. The test was aimed at assessing the level of mathematical literacy of future teachers, for whom teaching mathematics will be a part of their professional activities. The test tested not only the knowledge of terms and the ability to give definitions, but also the ability to correctly apply mathematics to solve practical problems with subsequent interpretation, as well as the ability to see errors and inaccuracies in the texts of students' works, Internet sources and teaching aids. The authors identified criteria for assessing the test results and for each criterion; a quantitative indicator was determined equal to the number of correctly completed tasks. The low results of even third-year students show topicality of specific activities that could help improve the mathematical literacy of pedagogues.

The purpose of the work is to explore the point of view in Vasily Shukshin's short stories in its systematic and diverse manifestation. Topicality is provided by the exceptional significance of this category in narratology. The study of the point of view based on the material of short stories by Vasily Shukshin has been conducted for the first time. The article briefly traces the history of scientific understanding of the category of point of view in foreign and Russian philology and notes the variety of approaches and definitions in the formulation of the concept. The authors use the classification of Boris Uspenskij for analysis and consider the point of view in Vasily Shukshin's short stories in psychological, ideological (evaluative), spatial-temporal and phraseological terms. The positions of Boris Korman, Yuri Lotman, Wolf Schmid and Franz Karl Stanzel also take into account. The authors note the features of Vasily Shukshin's narration that affect the expression of the point of view in the text. Vasily Shukshin's short stories are characterised by a dynamic and frequent change of points of view, which indicates the technique of “montageˮ and similarities in this regard with cinematic techniques. The conclusions generalise the variety of ways and forms of expression of the point of view in the studied artistic material. The point of view in the considered stories is characterised by variability in the correlation of subjects of speech and subjects of consciousness, alternation of external and internal points of view, mutual transitions from one to the other, text interference and other hybrid phenomena.

Through the present manuscript, we are reporting for the first time the presence of Cyclophorus pfeifferi Reeve, 1861 in India. Previously, this species of land snail was reported only from South-East Asian countries Malaysia, Thailand, Cambodia and Vietnam. The specimens were collected during field sur- veys in Dampa Tiger Reserve in Mizoram state, India. The presence of C. pfeifferi in India reveals the range expansion and long-distance dispersal abilities of the species. Here we discuss the taxonomy, ecology and possible routes of dispersal of the species in India.
