Матриксины 2, 7 и 9 при раке молочной железы: выяснение возможной связи с концентрацией белка HER-2/neu

The comparative analysis of the quantity of matrix metalloproteinases (MMP) 2,7 and 9 in breast cancer is carried out; the concentration of sex hormones receptors and protein HER-2/neu are determined. Authentically high values MMP-2 and MMP-7 are found in a tumor tissue in contrast to the normal one. The elevated concentration of ММР-2 in a tumor is connected with receptor status (p < 0,05). The highest values of concentration ММР-7 and ММP- 9 are found at RE-, RP- and HER-2/neu + tumors, and also in the tumors with the size more than 4,0 cm.Проведен сравнительный анализ содержания матриксных металлопротеиназ (ММП) 2,7 и 9 в опухолевых тканях молочной железы и гистологически неизмененной ткани, определено содержание рецепторов половых гормонов, белка her-2/neu. Достоверно высокие значения ММП-2 и -7 обнаружены в ткани опухоли по сравнению с гистологически неизмененной тканью. Повышение концентраций ММР 2 в опухоли связано с рецепторным статусом опухоли (p < 0,05). Наиболее высокие значения концентраций ММР-7 и ММР-9 обнаружены при РЭ-, РП- и HER-2/neu+ опухолях, а также в новообразованиях размером более 4,0 см

Relativistic Laser-Matter Interaction and Relativistic Laboratory Astrophysics

The paper is devoted to the prospects of using the laser radiation interaction with plasmas in the laboratory relativistic astrophysics context. We discuss the dimensionless parameters characterizing the processes in the laser and astrophysical plasmas and emphasize a similarity between the laser and astrophysical plasmas in the ultrarelativistic energy limit. In particular, we address basic mechanisms of the charged particle acceleration, the collisionless shock wave and magnetic reconnection and vortex dynamics properties relevant to the problem of ultrarelativistic particle acceleration.Comment: 58 pages, 19 figure

The origins and spread of domestic horses from the Western Eurasian steppes

Analysis of 273 ancient horse genomes reveals that modern domestic horses originated in the Western Eurasian steppes, especially the lower Volga-Don region.Domestication of horses fundamentally transformed long-range mobility and warfare(1). However, modern domesticated breeds do not descend from the earliest domestic horse lineage associated with archaeological evidence of bridling, milking and corralling(2-4) at Botai, Central Asia around 3500 bc(3). Other longstanding candidate regions for horse domestication, such as Iberia(5) and Anatolia(6), have also recently been challenged. Thus, the genetic, geographic and temporal origins of modern domestic horses have remained unknown. Here we pinpoint the Western Eurasian steppes, especially the lower Volga-Don region, as the homeland of modern domestic horses. Furthermore, we map the population changes accompanying domestication from 273 ancient horse genomes. This reveals that modern domestic horses ultimately replaced almost all other local populations as they expanded rapidly across Eurasia from about 2000 bc, synchronously with equestrian material culture, including Sintashta spoke-wheeled chariots. We find that equestrianism involved strong selection for critical locomotor and behavioural adaptations at the GSDMC and ZFPM1 genes. Our results reject the commonly held association(7) between horseback riding and the massive expansion of Yamnaya steppe pastoralists into Europe around 3000 bc(8,9) driving the spread of Indo-European languages(10). This contrasts with the scenario in Asia where Indo-Iranian languages, chariots and horses spread together, following the early second millennium bc Sintashta culture(11,12).Descriptive and Comparative Linguistic

Crystal chemistry of lanthanide oxochlorotungstates

Crystal chemical properties of lanthanide oxochlorotungstates of composition LnWO4Cl (Ln=La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm) are reported. The unit cell parameters a, b, c, c', and V of the LnWO 4Cl compounds are correlated with lanthanide ionic radii from different radius systems and with the lanthanide atomic number. The ionic radius systems most suitable for describing the crystal chemical properties of the lanthanide oxochlorotungstates are determined. © 2008 Pleiades Publishing, Ltd

State support mechanisms for business in the context of coronavirus pandemia

The spread of coronavirus infection and the subsequent introduction of restrictive measures have brought the economy into a new reality that has no examples of implementation in the past. The Russian government is faced with the acute problem of developing and implementing optimal management solutions. The article investigates the main support measures developed by the government of the Russian Federation. The authors compare these measures with measures implemented in other countries. Based on the comparison of the scale of the state participation, it is concluded that it is necessary to expand the package of anti-crisis measures and their preferential financing at the expense of the national welfare fund (NWF)

Functional Dyspepsia in Adults: Diagnosis and Treatment

The objective of the work was to determine the dynamics of clinical symptoms of functional dyspepsia in adults under the influence of treatment using M-cholinolytic (scopolamine butylbromide). We examined 45 patients with functional dyspepsia, 30 of them received M-cholinolytic (scopolamine butylbromide) in addition to integrated treatment. As a result of administration of this drug, clinical and instrumental parameters improved. In adjustment of drug dosage and duration of its administration, side effects weren’t detected
