The collection of <I>Allium</I> L. at the South-Ural Botanical Garden–Institute

The article presents the results of introducing wild species. forms and varieties of Allium L. in the South-Ural Botanical Garden– Institute, Ufa. This genus is known for many useful plants – edible, medicinal and ornamental – and for its rare species requiring protection. The collection contains 111 taxa: 92 species, plus a number of onion cultivars and forms. It includes 7 species listed in the Red Book of Bashkortostan, 35 rare species from other regions of the ex-USSR, 2 rare species from the Red Book of the Russian Federation, and 19 endemic species.The collection serves as the basis for studying biological characteristics, agronomic and ornamental traits, reproduction and in vitro cultivation features, etc. Biochemical composition of introduced genotypes is also analyzed. Special attention is paid to the cultivation of rare onions as one of the methods of preserving their biodiversity – their reintroduction into natural habitats is possible on this basis. Most of onions introduced into the Bashkir Cis-Urals (65 species, 78 taxa in total) are stable in cultivation and possess valuable food and/or ornamental qualities, which makes it possible to recommend them for wider use in gardening and phytodesign

Composition of oils in Vereiskian and Bashkirian carbonate reservoirs of the Akanskoe oilfield in the Republic of Tatarstan

The mineral and organic components of the core material from Vereiskian and Bashkirian deposits of the Akanskoe field in the Republic of Tatarstan have been studied by complex thermal analysis. The occurrence depth intervals with abnormally light oil have been revealed in the Bashkirian deposits. These facts together with the data on the composition of oils (high values of the ratio of light to heavy alkane homologues for heavier and more viscous Bashkirian crude oils, the bimodal MMD character of C 9-C 20 n-alkanes, and enrichment in high-molecular-mass asphaltenes at the bottom of the reservoir) suggest the influx of a lighter oil to the formed Bashkirian deposit. No facts of this sort have been identified for the Vereiskian oil. © 2012 Pleiades Publishing, Ltd

Results of the COVID-19 mental health international for the general population (COMET-G) study.

INTRODUCTION: There are few published empirical data on the effects of COVID-19 on mental health, and until now, there is no large international study. MATERIAL AND METHODS: During the COVID-19 pandemic, an online questionnaire gathered data from 55,589 participants from 40 countries (64.85% females aged 35.80 ± 13.61; 34.05% males aged 34.90±13.29 and 1.10% other aged 31.64±13.15). Distress and probable depression were identified with the use of a previously developed cut-off and algorithm respectively. STATISTICAL ANALYSIS: Descriptive statistics were calculated. Chi-square tests, multiple forward stepwise linear regression analyses and Factorial Analysis of Variance (ANOVA) tested relations among variables. RESULTS: Probable depression was detected in 17.80% and distress in 16.71%. A significant percentage reported a deterioration in mental state, family dynamics and everyday lifestyle. Persons with a history of mental disorders had higher rates of current depression (31.82% vs. 13.07%). At least half of participants were accepting (at least to a moderate degree) a non-bizarre conspiracy. The highest Relative Risk (RR) to develop depression was associated with history of Bipolar disorder and self-harm/attempts (RR = 5.88). Suicidality was not increased in persons without a history of any mental disorder. Based on these results a model was developed. CONCLUSIONS: The final model revealed multiple vulnerabilities and an interplay leading from simple anxiety to probable depression and suicidality through distress. This could be of practical utility since many of these factors are modifiable. Future research and interventions should specifically focus on them

Case of uterine scar rupture in the second trimester of pregnancy after preceding caesarean section

Uterine rupture is one of the rare and severe complications of pregnancy and childbirth. It most often occurs in the third trimester however there are publications on cases of uterine rupture in the second trimester. In the available Russian literature we were unable to find any publications regarding uterine scar rupture in the second trimester after preceding caesarean section; available publications focus on uterine scar rupture after preceding myomectomy. Prevalence of caesarean section has recently increased dramatically both in the world and in Russia, besides the data about possibility of pregnancy prolongation in case of uterine scar rupture appeared. It encouraged us to present clinical observation. It demonstrates that uterine scar rupture in the early stages of pregnancy is paucisymptomatic and is often considered as a threatening miscarriage. It is necessary to remember that threatening miscarriage is usually characterized by shortening and softening of the cervix which are not observed in case of threatening or accomplished uterine scar rupture. As such factors, as the time of uterine rupture symptoms occurence, gestational age, localization of placenta, absence of placenta rotation, fetal viability, size of the uterine scar and the characteristics of scar rupture are the main predictors for the decision of pregnancy prolongation in case of uterine scar rupture, so the early diagnosis of such condition is of great importance
