Geochemical features of Kulunda plain lakes (Altay region, Russia)

Geochemical specifics of lake water of the Kulunda Steppe territory (Altay region, Russia) are studied. The results show that in the territory mainly chloride and less soda lakes with sodium compound are developed. It is presented that calcite and soda saturation indexes (SI) of lake water increase with growth of pH, but decrease in such minerals as gypsum and barite. The opposite situation is typical for SI depending on the salinity. It is revealed that evaporation, secondary mineral formation and various biological processes have the greatest impact on accumulation of elements in solution

Analysis of Collectivism and Egoism Phenomena within the Context of Social Welfare

Comparative benefits provided by the basic social strategies including collectivism and egoism are investigated within the framework of democratic decision-making. In particular, we study the mechanism of growing "snowball" of cooperation.Comment: 12 pages, 5 figures. Translated from Russian.

Molecular beam epitaxy of high structural quality Bi2Se3 on lattice matched InP(111) substrates

Epitaxial layers of the topological insulator Bi2Se3 have been grown by molecular beam epitaxy on laterally lattice-matched InP(111)B substrates. High resolution X-ray diffraction shows a significant improvement of Bi2Se3 crystal quality compared to layers deposited on other substrates. The measured full width at half maximum of the rocking curve is Delta omega=13 arcsec, and the (omega-2theta) scans exhibit clear layer thickness fringes. Atomic force microscope images show triangular twin domains with sizes increasing with layer thickness. The structural quality of the domains is confirmed on the microscopic level by transmission electron microscopy.Comment: 4 pages, 4 figure

COMPLEMENTARITY OF MEDICAL, SOCIAL AND PSYCHOLOGICAL CARE IN TUBERCULOSIS CONTROL (AS REPORTED BY DOCTORS AND PATIENTS)

Questionnaire survey in 236 doctors and 584 patients has shown that provision of social and psychological support to tuberculosis patients is very limited despite the significant demand for it, which provides negative impact on treatment and rehabilitation results. The article presents various possible actions aimed to improve this situation

КОМПЛЕМЕНТАРНОСТЬ ОКАЗАНИЯ МЕДИЦИНСКОЙ, СОЦИАЛЬНОЙ И ПСИХОЛОГИЧЕСКОЙ ПОМОЩИ ВО ФТИЗИАТРИИ (в оценках врачей и пациентов)

Questionnaire survey in 236 doctors and 584 patients has shown that provision of social and psychological support to tuberculosis patients is very limited despite the significant demand for it, which provides negative impact on treatment and rehabilitation results. The article presents various possible actions aimed to improve this situation.Анкетирование 236 врачей и 584 пациентов показало, что оказание пациентам фтизиатрического профиля как социальной, так и психологической помощи носит, несмотря на несомненную восстребованность в них, очень ограниченный характер, что отрицательно сказывается на результатах лечебно-реабилитационного процесса. В данном контексте предложены возможные корректирующие мероприятия

Эффективность фотодинамической терапии больной ранним центральным раком лёгкого и муковисцидозом

oai:oai.bioph.elpub.ru:article/349The authors describe a clinical observation with full clinical effect after multi-course photodynamic therapy of a patient with central lung cancer and cystic fibrosis using Photoditazine. Photoditazine was administered intravenously at a dose of 0.8 mg/kg 2 hours before the irradiation session. Irradiation parameters: power density – 150 mW/cm2, energy density – 200 J/cm2. In total, 3 courses of photodynamic therapy were performed. As a result of the treatment, a complete regression of the tumor was noted. The patient has been under dynamic observation for 2 years after treatment, no relapse was observed.Авторы описывают клиническое наблюдение с полным клиническим эффектом после многокурсовой фотодинамической терапии больной центральным раком легких и муковисцидозом с использованием фотодитазина. Фотодитазин вводили внутривенно в дозе 0,8 мг/кг за 2 ч до проведения сеанса облучения. Параметры облучения: плотность мощности – 150 мВт/см2, плотность энергии – 200 Дж/см2. Всего было проведено 3 курса фотодинамической терапии. В результате проведенного лечения отмечена полная регрессия опухоли. Пациентка находится под динамическим наблюдением в течение 2 лет после лечения, рецидива не выявлено

Multidrug Resistance of <i>F. tularensis</i> subsp. <i>holarctica</i>, Epizootiological and Epidemiological Analysis of the Situation on Tularemia in the Russian Federation in 2022 and Forecast for 2023

The review provides concise information on the innate ability of cells of the tularemia pathogen, Francisella tularensis subsp. Holarctica, to resist antimicrobials through a variety of mechanisms, leading to its multi-resistance. In total, taking into account new territories, 120 cases of human infection were registered in the Russian Federation in 2022. Epizootic manifestations of the infection of varying degrees of intensity were detected in 58 constituent entities. Against this background, sporadic cases of tularemia in humans were reported in 18 regions of the country. An outbreak of tularemia occurred in the Stavropol Territory; the disease of mild and moderate severity was found in 76 people. The increased incidence of tularemia persists in the Republic of Karelia with severe cases of the disease in the absence of immunoprophylaxis of this infection in the region. A total of 61 cultures of the tularemia pathogen F. tularensis subsp. holarctica, out of which 20 erythromycin-resistant strains were isolated in the Stavropol Territory. In addition, 8 cultures of F. tularensis subsp. mediasiatica from a silt sample and mites Dermacentor silvarum and Haemaphysalis concinna caught in the Republic of Altai were isolated. On the territory of the Russian Federation in 2022, 930 999 people were vaccinated and revaccinated against tularemia. Based on the analysis of the data obtained in 2022, epidemic complications in 2023 in the form of sporadic cases of the disease among the unvaccinated population are most likely to occur in the territories of the Central Federal District – in the Vladimir, Ryazan and Smolensk Regions; Northwestern Federal District – in the Arkhangelsk Region and the Republic of Karelia; Southern Federal District – in the Volgograd and Rostov Regions. The situation in the North Caucasian Federal District will remain tense in the Stavropol Territory; in the Volga Federal District – in the territories of the Saratov Region, as well as in the Kirov Region and the Republic of Mordovia; Ural Federal District – in Khanty-Mansi and Yamalo-Nenets Autonomous Districts; Siberian Federal District – in certain territories of Omsk, Kemerovo, Tomsk, Novosibirsk, Irkutsk Regions, Altai, Krasnoyarsk Territories; in the Far Eastern Federal District, the most intense epizootic activity of natural tularemia foci is in Primorsky Krai
