Activation of Systemic Inflammation and Oxidative Stress in Adolescent Girls with Polycystic Ovary Syndrome in Combination with Metabolic Disorders and Excessive Body Weight
The goal of this study is to estimate the prevalence of metabolic syndrome (MetS), together with its components and correlates, among elderly Russians. MetS was defined according to National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATPIII). The prevalence of MetS was found to be 41.7% in women and 26.8% in men. It tended to decrease with age in men, but not in women. MetS was inversely related to education in women, but not in men. The most prevalent individual components of MetS were as follows: hypertension (64.4%), abdominal obesity (55%), and decreased high density lipoprotein cholesterol (46%) for women; and hypertension (71%) and fasting hyperglycemia (35.2%) for men. The higher female prevalence of MetS was attributable to abdominal obesity. MetS was found to be associated with markers of insulin resistance, low-grade inflammation, and insufficient fibrinolysis. Although the metabolic burden is an important contributor to high levels of ill-health and cardiovascular mortality among elderly Russians (especially women), it does not explain why cardiovascular mortality is much higher in Russia than in other industrialized countries.
C-Fos was initially described as oncogene, but was associated with favourable prognosis in ovarian cancer (OvCa) patients. The molecular and functional aspects underlying this effect are still unknown.
Using stable transfectants of SKOV3 and OVCAR8 cells, proliferation, migration, invasion and apoptotic potential of c-FOS-overexpressing clones and controls were compared. Adherence to components of the extracellular matrix was analysed in static assays, and adhesion to E-selectin, endothelial and mesothelial cells in dynamic flow assays. The effect of c-FOS in vivo was studied after intraperitoneal injection of SKOV3 clones into SCID mice, and changes in gene expression were determined by microarray analysis.
Tumour growth after injection into SCID mice was strongly delayed by c-FOS overexpression, with reduction of lung metastases and circulating tumour cells. In vitro, c-FOS had only weak influence on proliferation and migration, but was strongly pro-apoptotic. Adhesion to components of the extracellular matrix (collagen I, IV) and to E-selectin, endothelial and mesothelial cells was significantly reduced in c-FOS-overexpressing OvCa cells. This corresponds to deregulation of adhesion proteins and glycosylation enzymes in microarray analysis.
In addition to its known pro-apoptotic effect, c-FOS might influence OvCa progression by changing the adhesion of OvCa cells to peritoneal surfaces.
This book presents the results of analysis of human capital in Murmansk and Archangelsk regions, republics of Komi and Karelia, and Nenets Autonomous Region. The authors considered migration processes and their trends; some of these were analyzed at municipal level. Having taken in account the importance of life expectancy as a complex indicator of sustainable development, the authors identified the periods of its growth and decline. Age-specific differences were also scrutinized. The relative contributions of major causes of mortality in life expectancy at birth were estimated. The authors described the dynamics of population of small indigenous peoples of the North (Vepsians, Nenets, Komi), the problems associated with their self-identification, census administration, migration, childbirth and life expectancy. The authors analyzed climate change as the new health risk factor, which affects safety of food and drinking water, accessibility of medical services and specific practices of deer-herding. A separate chapter of the book is devoted to current and future trends in working-age population until 2002. Each territory of Barents Sea Region displayed its own peculiar behavior of this indicator. The authors compared selected social, economic and demographic indicators in European part of Russian Arctic with those in foreign countries which belong to Barents Sea Region. This monograph was a product of collaborative efforts of the researchers from Economic Forecasting Institute and Institute of Demography of Higher School of Economics. B. A. Revich, Doctor of Medicine, and B. N. Porfiryev, Corresponding Member of Russian Academy of Sciences, edited this book.
In the internal medicine wide spectrum the gastroenterology is one of the chapters, less enlightened by the scientific evidence. It does not mean that the practice of the grasntroenterology may ot be improved by the systematic use of the approaches of the evidence based medicine
This prototype development explains the challenges encountered during the ISO/IEEE 11073 standard implementation process. The complexity of the standard and the consequent heavy requirements, which have not encouraged software engineers to adopt the standard. The developing complexity evaluation drives us to propose two possible implementation strategies that cover almost all possible use cases and eases handling the standard by non-expert users. The first one is focused on medical devices (MD) and proposes a low-memory and low-processor usage technique. It is based on message patterns that allow simple functions to generate ISO/IEEE 11073 messages and to process them easily. MD act as X73 agent. Second one is focused on more powerful device X73 manager, which do not have the MDs' memory and processor usage constraints. The protocol between Agent and Manager is point-to-point and we can distribute the functionality between devices.
Developed both implementation X73 Agent and Manager will cut developing time for applications based on ISO/EEE 11073.
