BACKGROUND: Family quality of life (F-QOL) is necessarily issued for in fulfilling nutrition among under-five children that influenced their growth and development. OBJECTIVE: To examine the prevalence of malnutrition and stunting among under-five children and their correlation of F-QOL in agricultural areas of Jember regency, Indonesia METHOD: A cross-sectional study through a family based-survey was conducted among 424 family farmers in Jember regency of Indonesia November to December 2019 using a self-administered questionnaire consisted the characteristics of parents and children, quality of family life, family welfare, family awareness, and measurements of children’s age, height, and weight to identify stunting and malnutrition. T-tests of independence and the One Way ANOVA test was used to correlate the categorical and continuous variables, respectively. Furthermore, to determine the correlation among constant variables, we used a Product Moment test. RESULTS: Prevalence of wasted, stunted, and malnutrition among under-five children in agricultural areas were 3%, 18.9%, and 5%. There was a significant correlation between ethnic of family and type of family with HAZ ( p = 0.007), respectively. Meanwhile, there was a significant correlation between WAZ and age of children ( r = 0.106; p < 0.05). Furthermore, there were significantly correlation between FQOL and WAZ ( r = 0.260; p < 0.01) and HAZ FQOL ( r = 0.209; p < 0.01), respectively. CONCLUSION: Malnutrition and stunting are the biggest problems of nutritional status in Indonesia’s agricultural areas correlated with ethnicity and type of family.

Ammonium hexafluorosilicates as potential anti-caries agents: the problem of cation selection
Authors: Гельмбольдт В. О. , Литвинчук І. В. 
Published: May 2021

In the last decade, ammonium hexafluorosilicate (AHFS) and ammonium hexafluorosilicates with biologically active cations (AHBAC), which have certain advantages over traditional fluoride medicinal substances, have been actively studied as anti-caries agents. In particular, an important feature of the action of AHFS is its ability to cause prolonged occlusion of the dentinal tubules with a precipitate of calcium fluoride; when using AHBAС there is a possibility of strengthening the anti-caries activity of the substance due to the pharmacological potential of the cation.
The purpose of the review is to analyze the effects of the cation on the physicochemical properties and biological activity of ammonium hexafluorosilicates as potential anti-caries agents.
Research methods – bibliosemantic, content analysis.
It was drew the attention to the peculiarity of the AHBAC structure: salt structures are formed on the basis of systems of strong interionic H-bonds, mainly of the NH···F type, which have a significant effect on the properties of hexafluorosilicates in the crystalline state and their behavior in solutions. It was demonstrated the non-trivial nature of the change of solubility in water of AHBAC with heterocyclic and aromatic cations, which consists in the decrease of solubility with increasing number of hydrophilic fragments in the structure of cations. Adequate 2D QSPR models for interpretation and virtual screening of AHBAC water solubility have been constructed. Accounting for the effect of H-bonds on the solubility of AHBAC was detailed. It was assumed that the process of hydrolysis of AHBAC in aqueous solutions can be stimulated by elongation of the Si–F anion bonds due to the effects of H-bonds. It is shown that the thermal stability of AHBAC with pyridinium cations symbatically correlates with the number of strong and medium H-bonds in salt structures.
The action of the pharmacological effects of the cation on the biological activity of AHBAC is manifested in the form of an increase in the caries-prophylactic efficacy of AHBAC in comparison with a similar effect of AHFS. Attempts to establish a relationship between the anti-caries activity of AHBAC and a certain pharmacological action of the cation have led to mixed results. This obviously reflects the complex mechanism of the influence of the biological activity of the cation on the caries-prophylactic efficacy of hexafluorosilicates, which is not limited to any one, albeit dominant, type of activity.

Flavonoids have attracted the phytochemical scientists attention since their discovery. Today, with the COVID-19 pandemic, have been information about a favorable therapeutic effect in the treatment dynamics of simultaneously taking treatment protocol drugs with traditional Chinese medicine (dietary supplements of plant origin, separate isolated natural compounds) for more than 85% of Chinese patients infected with SARS-CoV-2.
Have been presence and content of flavonoids as a class of natural compounds genetically related to the development and accumulation of benzo-α-pyrone derivatives in the aerial part of 20 alfalfa varieties from different breeding sites in the South of Ukraine introduction. The studies were carried out in 2015–2019. Accounting for the main traits and phenological observations of plant development were carried out according to the method field and laboratory research. The cultivation has been carried out on the territory of the southern part left bank Ukraine (on the border of the forest steppe and steppe zones).
The raw material for analysis (alfalfa herb) was harvested by cutting off the plants in the flowering stage, dried in the shade, under a canopy, turned over periodically.
Solutions for the flavonoids determination were obtained by boiling a crushed raw materials sample with ethanol (70% v/v).
Chromatographic separation has been performed on a Shimadzu LC-20 Prominence liquid chromatograph (Shimadzu, Japan) with a Phenomenex Luna C18 column (2); column temperature 35 °C; detection wavelength – from 270 nm to 520 nm; the separation mode is gradient with a constant rate flow of the mobile phase 1 ml/min. The injection volume is 0.5 μl.
The compounds presence and content in the alfalfa varieties obtained extracts vary widely enough under the same conditions of sowing, processing, and growing.
The Tajik variety Vakhshskaya 233 is the leader in the content of luteolin-7-glucoside. The American variety WL 508 is the richest in routine (0.50920 mg/g). Cinnamic acid was found in maximum quantities in the Mexican variety Tanhuato (0.24406 mg/g), and this component is completely absent in the Ukrainian variety Sinyukha.

Several social, psychological and biological factors could be cause for central nervous system disorders, especially anxiety; the latter could lead to more serious neurological and psychosomatical disorders. Sedative medications of plant origin are widely used practically as an alternative and/or additive to traditional pharmacological treatments of anxiety, hyperexcitation and other neuroses. Thus, the search of new effective sedatives based on plant extracts is an actual and perspective task.
Aim of the present work is to investigate the sedative effect of biomass extract from cell culture of Rauwolfia serpentina K-27 strain.
Sedative action of biomass extract from cell culture of Rauwolfia serpentina high-productive strain was determined by open field method on 24 white mice males (no line). Mice weight was in 18–25 g interval. The behavior was assessed by usual behavioristic acts: motor activity, psychoemotional activity and tentative research reaction. Animals were randomized into 3 groups of 8 individuals each. Rauwolfia serpentina biomass extract at doses of 7.5 mg/kg (group 1) or 15 mg/kg (group 2) was administered orally as an aqueous solution. Animals of the control group (group 3) received a solvent (distilled water).
The sedative effect of extract was discovered in doses of 7.5 and 15 mg/kg, that showed a decrease in horizontal motor activity to 63.31 and 79.76% respectively, vertical activity to 82.05 and 71.79%, grooming duration to 57.28 and 60.78% at experimental days 20 to 28. Tentative research reaction demonstrated the direct dependence of sedation intensity on duration of extract administration. As a result of the conducted researches significant differences in the number of fecal bolus of both experimental and control groups of mice were not revealed. No significant difference between the sedative effect and the dose (7.5 and 15 mg/kg) was observed.
The sedative effect of biomass extract from cell culture of Rauwolfia serpentina K-27 strain was proven. This leads to perspective inclusion of the extract to traditional medicine in prophylaxis and treatment of insomnia and of physical and psychological overexcitation.

Conventional radiographs provide only a 2 dimensional view of complicated three dimensional structures. The proximity, angulations, location of impacted teeth, related to the IAN can be adequately determined using conventional 2-D periodical and panoramic radiographs. Computed tomography necessitates the administration of a high dose radiation, especially when the slice width is shortened to increased cost are the negative aspects of computed tomography compared with conventional imaging.
Cone beam computed tomographies are becoming more readily available for use in maxilla facial applications. CBCT provides better image quality of teeth and their surrounding structures, compared with conventional CT and offers high spatial resolution. CBCT seems to be more accurate data about inferior alveolar canal. Hence the present study was undertaken to assess and select roots of third molar with close proximity to inferior dental canal in panoramic radiograph having radiographic signs of darkening of root, disruption of canal cortex and canal deviation and to evaluate the same roots with CBCT using trans axial and coronal sections which is angulated parallel to long axis to tooth, axial and coronal sections for proximity of inferior dental canal with the apices of third molar root.

Published: May 2021

ABSTRACTSasmita gendhing is a series of words that lead to the name gendhing-gendhing as a supporter of the wayang kulit purwa show. While the wayang kulit show format still refers to the format of last night's show with the genre of palace performance, the gendhing grade became a bridge between the mastermind and the singer to sound the gendhing as a support for certain scenes. In the development of the existence of gendhing-gendhing grades are slowly declining, even the majority of masterminds no longer use gendhing grades. The text-context approach from HeddyShri Ahimsa is used to reveal the variety of gendhing grades and to find the cause of the decline in the use of gendhing grades. The study conducted found various forms of gendhing grades, among them, are figurative words, wangsalan, and cangkriman. While the cause of the decline in the use of gendhing grades is noted due to the change of image, freedom of scene structure, freedom of choice of play, and cross-style performance. Keywords: gendhing grades, text-context, performance ABSTRAKSasmita gendhing merupakan rangkaian kata yang mengarah pada nama gendhing-gendhing sebagai pendukung pertunjukan wayang kulit purwa. Ketika format pertunjukan wayang kulit masih mengacu pada format pertunjukan semalam dengan genre pakeliran istana, sasmita gendhing menjadi jembatan antara dalang dengan pengrawit untuk membunyikan gendhing sebagai pendukung adegan tertentu. Dalam perkembangannya eksistensi sasmita gendhing- gendhing perlahan surut, bahkan mayoritas dalang tidak lagi menggunakan sasmita gendhing. Pendekatan teks-konteks dari HeddyShri Ahimsa digunakan untuk mengungkap ragam sasmita gendhing serta mencari penyebab surutnya penggunaan sasmita gendhing. Dari kajian yang dilakukan ditemukan beragam bentuk sasmita gendhing, di antaranya adalah kata kiasan, wangsalan, dan cangkriman. Sedangkan penyebab surutnya penggunaan sasmita gendhing ditengarai karena adanya perubahan citra, kebebasan struktur adegan, kebebasan pemilihan lakon, dan silang gaya pakeliran.
