The morphological features of the granary weevil, Sitophilus granarius (L.), which are used in sexing the adults, were studied by scanning electron microscopy. The rostrum of the female is nearly 10% longer and 15% thinner than that of the male. The terminal segments of the male's abdomen are deflected downward about 30° from the longitudinal axis of the body while the tip of the female's abdomen remains close to the horizontal plane of the body.

Today methyl bromide is being used throughout the world to control insect pests. Intrinsically it is not among the most toxic of insect fumigants, but it has a combination of properties which gives it an unique position among gaseous insecticides. Of particular importance are its powers of penetration and its non-inflammability under normal fumigating conditions. Methyl bromide is important also as the leading fumigant in a group, the halogenated hydrocarbons, which includes other widely used fumigants such as ethylene dibromide, ethylene dichloride, and ethylene chlorobromide.

The new SARS-CoV-2 belonging to the coronaviruses family has caused a pandemic affecting millions of people around the world. This pandemic has been declared by the World Health Organization as an international public health emergency. Although several clinical trials involving a large number of drugs are currently underway, no treatment protocol for COVID-19 has been officially approved so far. Here we demonstrate through a search in the scientific literature that the traditional Moroccan pharmacopoeia, which includes more than 500 medicinal plants, is a fascinating and promising source for the research of natural molecules active against SARS-CoV-2. Multiple in-silico and in-vitro studies showed that some of the medicinal plants used by Moroccans for centuries possess inhibitory activity against SARS-CoV or SARS-CoV-2. These inhibitory activities are achieved through the different molecular mechanisms of virus penetration and replication, or indirectly through stimulation of immunity. Thus, the potential of plants, plant extracts and molecules derived from plants that are traditionally used in Morocco and have activity against SARS-CoV-2, could be explored in the search for a preventive or curative treatment against COVID-19. Furthermore, safe plants or plant extracts that are proven to stimulate immunity could be officially recommended by governments as nutritional supplements.

In order to identify promising strategic development possibilities for the pharmaceutical industry in the Russian Federation, a pilot study was conducted, which has analyzed the main trends in the development of innovative medicines. As a result of the content analysis of available sources of scientific literature, the characteristics of options used in the world practice for increasing the innovative activity of individual subjects and the pharmaceutical market as a whole are presented. Possible reserves for the further development of the innovative component of the pharmaceutical market within the framework of the concept of personalized medicine according to the P4 principle (predictive - personalized - preventive - participatory) are identified and structured. The results of use by individual pharmaceutical companies of scientifically and practically justified approaches to optimizing the costs of development and promoting drugs are presented. The advantages and real prospects of a generally accepted method to reduce the cost of development by «expanding the pharmacological effect» (label expansion) of already existing drugs with a known safety profile in the world practice are shown. A scientific generalization and structuring of the goals and results of the post-registration phase of clinical trials to expand the pharmacological action of a number of drugs already existed at the market have been carried out.

The author considers the problems of typification of society. Some concepts of typification of social stratification models in different countries formulated and justified in historical and legal, historical, sociological, and economic scientific literature are reviewed. The circumstances that make it difficult to formulate universal concepts designed for application in the complex of social Sciences are identified. These circumstances include insufficient consideration of legal factors, including the position of the legislator, the specifics of the corporate legal status, and the characteristics of the mechanism for changing individual legal status. The author offers a variant of classification of society types from the point of view of legal registration of their structure. The possibility of distinguishing types such as consolidated companies and segmented companies is justified.

The Mimosa genus belongs to the Fabaceae family of legumes and consists of about 400 species distributed all over the world. The growth forms of plants belonging to the Mimosa genus range from herbs to trees. Several species of this genus play important roles in folk medicine. In this review, we aimed to present the current knowledge of the ethnogeographical distribution, ethnotraditional uses, nutritional values, pharmaceutical potential, and toxicity of the genus Mimosa to facilitate the exploitation of its therapeutic potential for the treatment of human ailments. The present paper consists of a systematic overview of the scientific literature relating to the genus Mimosa published between 1931 and 2020, which was achieved by consulting various databases (Science Direct, Francis and Taylor, Scopus, Google Scholar, PubMed, SciELO, Web of Science, SciFinder, Wiley, Springer, Google, The Plant Database). More than 160 research articles were included in this review regarding the Mimosa genus. Mimosa species are nutritionally very important and several species are used as feed for different varieties of chickens. Studies regarding their biological potential have shown that species of the Mimosa genus have promising pharmacological properties, including antimicrobial, antioxidant, anticancer, antidiabetic, wound-healing, hypolipidemic, anti-inflammatory, hepatoprotective, antinociceptive, antiepileptic, neuropharmacological, toxicological, antiallergic, antihyperurisemic, larvicidal, antiparasitic, molluscicidal, antimutagenic, genotoxic, teratogenic, antispasmolytic, antiviral, and antivenom activities. The findings regarding the genus Mimosa suggest that this genus could be the future of the medicinal industry for the treatment of various diseases, although in the future more research should be carried out to explore its ethnopharmacological, toxicological, and nutritional attributes.

Abstract The red-billed quelea is a small weaver bird native to sub-Saharan Africa and renowned for its attacks on small-grain crops within Africa. It is the most numerous bird species in the world, with peak post-breeding population estimated at 1,500,000,000. The red-billed quelea is mainly granivorous, except when feeding its chicks insects or when eating insects prior to migration or breeding, and it relies on a supply of grass seeds to survive. When unable to find grass seeds or when opportunities arise, quelea will attack crops. It is a major pest throughout much of sub-Saharan Africa and can cause significant economical losses.

Abstract Scientific literature has tackled Maltese English (MaltE) mainly in the framework of World Englishes in order to focus on its features compared to other varieties of English around the world. In this paper we shed more light on MaltE by proposing a sociolinguistic perspective, oriented towards its social stratification, and by referring to it through degrees of linguistic competence in English. We therefore propose two continua of variation: MaltE as an L2 continuum and as a situational one. Within this framework, we identify two groups defined as Mainly Maltese Speakers (MMS) and Mainly English Speakers (MES). We suggest that MaltE can be interpreted both as an L2, and as a variety used according to speech events, domain, participants, in-groupness etc. To investigate this we carried out a perceptual experiment involving two groups of university students, specialising in Maltese and English respectively. We discuss the results based on ratings and evaluations of authentic MaltE written and spoken prompts.

As a further step towards the modernization of acupuncture, the objective of this review was to figure out the frequency and severity of adverse complications and events in acupuncture treatment reported from 1980 to 2013 in China. All first-hand case reports of acupuncture-related complications and adverse events that could be identified in the scientific literature were reviewed and classified according to the type of complication and adverse event, circumstance of the event, and long-term patient outcome. The selected case reports were published between 1980 and 2013 in 3 databases. Relevant papers were collected and analyzed by 2 reviewers. Over the 33 years, 182 incidents were identified in 133 relevant papers. Internal organ, tissue, or nerve injury is the main complications of acupuncture especially for pneumothorax and central nervous system injury. Adverse effects also included syncope, infections, hemorrhage, allergy, burn, aphonia, hysteria, cough, thirst, fever, somnolence, and broken needles. Qualifying training of acupuncturists should be systemized and the clinical acupuncture operations should be standardized in order to effectively prevent the occurrence of acupuncture accidents, enhance the influence of acupuncture, and further popularize acupuncture to the rest of the world.
