AbstractOverlapping geographical occurrence, history of traditional use, confusion in species identification, and morphological resemblances among various species are some considerations that necessitate the importance of qualitative analysis for efficient quality control and safer botanical products. This paper provides detailed morpho-anatomies of the leaves and stems of Tinospora cordifolia, Tinospora crispa, and Tinospora sinensis, and stems of Tinospora baenzigeri. Microscopy studies of the selected Tinospora species revealed key diagnostic features that can help distinguish the closely related species of Tinospora as well as to detect any adulteration or substitution in the raw materials. HPTLC profiles of the authenticated plant materials, as well as commercial products claiming to contain Tinospora, were compared to distinguish T. crispa from other closely related species and to establish an efficient method to assess the identity and quality of the products using qualified chemical markers. HPTLC chromatograms of both plant samples and dietary supplements were compared with six reference marker compounds. The analysis revealed that borapetoside B and C were useful to identify T. crispa while tinosineside A was found to be characteristic to authenticate the T. sinensis products.

Comparative Description

1. The life history of N. battus is described, and a comparative description of the life history of N. filicollis is given.2. The life histories of these two species are compared with those of N. spathiger and N. helvetianus, two closely related species, and are shown to follow the same basic pattern, with minor variations in timing which appear to be specific in nature, and not related to differences in culture methods or host species.3. The pathogenesis of Nematodirus species is discussed and related to the migration of larvae into the intestinal mucosa during development.

The research featured the development of formulae and technologies for the production of biologically active additives (BAA) for functional foods with potential adaptogenic, antioxidant, and hepatoprotective properties. Shilajit, a natural mineral-organic substrate, and various plant materials were used as sources of natural biologically active substances (BAS). The relevance of the study comes from the need for more efficient use of natural biologically active compounds, as well as from the need to expand the range of domestic dietary supplements with natural ingredients, which resulted from the current import substitution. Scientific data and experimental studies made it possible to choose advantageous raw materials with BAS and to assess their safety and potential properties. An experiment determined the content of BAS in the raw materials and in the control samples. A compatibility test wasconducted by mixing. As a result, five formulae with various combinations of natural components in the composition were scientifically substantiated. The authors defined the physicochemical and technological properties of the mixtures of dry extracts that determined the choice of technology and the quality of the finished product. The present paper also describes technology of obtaining encapsulated dietary supplements based on dry extracts of medicinal plants and shilajit. The advantage of the technology lies in the use of natural components and special processing methods of BAS preservation. The research included the method of water-activated granulation while 20% ethyl was used as a wetting agent. To obtain the granulate, lactose (Russia) and AEROSIL® 200 Pharma (Evonik Industries, Germany) were used as additive agents. As a result, capsules with a dosage of 700 mg were developed. The BAA can be produced on food and pharmaceutical plants.

Layer Chromatography

The high-performance thin-layer chromatography (HPTLC) is widely used for quality control of herbal raw materials (HRM). The purpose of this work were to define the problematic issues of quality control of herbal drugs in Ukraine and to develop a systematic scientific and methodological approach for the standardization of HRM and herbal drugs using the modern analytical technique of HPTLC: to optimize the existing and develop new methods of identification and determination of adulterations, and to develop alternative methods of quantitative determination, as well as studying of the stability. As a result of a critical evaluation of existing approaches for the standardization of HRM and herbal drugs of Ukraine’s flora, numerous problematic issues were identified, including the existence of a limited number of national monographs / national parts of monographs on the HRM of the Ukraine’s flora, which were not previously standardized by other pharmacopeias; non-consideration of Ukraine’s flora species (non-pharmacopoeial) in monographs on closely related species that introduced in the State Pharmacopoeia of Ukraine; lack of specificity of combinations of physical and chemical methods used for quality control; lack of specificity and reproducibility, the labor intensity of methods; necessity of usage of toxic solvents and precursors; use of different groups of markers and methods for the HRM and its finished product or HRM and its closely related species, etc. The proposed systematic scientific and methodological approach includes: a preliminary collection of information about the object of study, markers/groups of bioactive substances, approaches to its standardization; theoretical evaluation of existing techniques of quality control in monographs on HRM and experimental approbation using samples of domestic plants, determination of the need for optimization of existed methods by the parallel development of specific, reproducible and documented methods for identification, adulterations’ detection, quantification, and bio-detection (if necessary) by HPTLC method. The approach is illustrated with examples. The proposed approach can be used for comprehensive HPTLC analysis of domestic HRM and herbal drugs for research, prevention of adulteration, standardization of initial HRM and its finished product, pharmaceutical development, and stability studies.

ABSTRACT The demographic history of Homo sapiens is complex; it involves a wide range of migrations and genetic adaptations. One of the closely related species to Homo sapiens is Neanderthals, which became extinct about 30,000 years ago. The aim of this research is to compare Homo sapiens with Neanderthals and chimpanzees to understand the patterns of inheritance and survival instincts of Homo sapiens. Results show that out of all selected groups of genes in this study, metabolism, and language genes are found to be the most evolving group of genes. This shows that these most evolving genes are contributing to the advancement of Homo sapiens. However, after comparing human intelligence genes with the primates, it is found that exonic regions are contributing more to the evolution of human intelligence hence, making Homo sapiens unique in terms of intelligence.

Coiled State

Some species of criocerine beetles have a hyper-elongated part of the intromittent organ called a flagellum. In resting position, the flagellum is stored in a specialized internal sac in the intromittent organ. This specialized state of the flagellum and internal sac is indispensable during copulation for flagellar insertion into the female spermathecal duct for sperm transfer. However, the morphogenesis of the flagellum does not generate the active state of the flagellum; rather, the flagellum is generated in an inactive and completely coiled state. After eclosion, males of Lema coronata evert and withdraw the internal sac multiple times before sexual maturation, without mounting a female. This behaviour serves to uncoil the flagellum and guide it into the active state with the aid of surface structures on the internal sac. A closely related species, Lema dilecta , also has a long flagellum and undergoes the same behaviour to place the flagellum in the active position. However, some other species of criocerine beetles with much shorter flagella can attain the active state without exhibiting this behaviour. Based on a previously proposed phylogenetic tree, we discuss the evolutionary history of the hyper-elongation of the flagellum and associated behaviour.

The quantitative analysis of diterpene acids in raw materials of closely related species of genus Salvia was carried out. The objects of present research were Salvia officinalis L., Salvia tesquicola Klokov and Pobed., Salvia nutans L., which grow in neighboring south (Samara and Orenburg) regions. During analysis different raw materials, such as herbs and leaves, were studied. It was determined that total amount of diterpene acids varies from 1,04% to 1,32% in leaves of different species of Salvia and from 1,13% to 1,67% in herbs of different species of Salvia. The raw material of Salvia nutans contains minimal amount of diterpene acids, but in the raw material of Salvia tesquicola the quantitative analysis shows different results, which depend on the region. The medical raw material of Salvia officinalis, which is cultivated in Samara region, includes sufficient amount of diterpene acids.

ABSTRACT Drosophila buzzatii has been found sympatric in Argentina with a closely-related sibling species, D. serido. The biogeographical, reproductive and chromosomal data allow us to combine these species into an evolutionary unit, the buzzatii cluster. Salivary gland chromosomes also have been used to determine their phylogenetic relationships with other closely related species, showing that the buzzatii cluster species share two inversions—2d  2 and 2s  6—with the species of the martensis cluster. Both clusters arose from South American populations of the ancestor of the mulleri complex, and we propose to include D. buzzatii and D. serido in the mulleri complex of the repleta group.
