This paper describes pregnancy outcomes and identifies their determinants in a Russian region, in the year 2000. It includes all births and perinatal deaths recorded as occurring in Tula oblast. The socio-economic correlates of adverse outcomes are explored using logistic regression; outcomes and their determinants are compared with other countries. Perinatal mortality in Tula in 2000 was 16.8/1000 births. The frequencies of low birthweight, low ponderal index and preterm birth were higher in Tula than in other industrialised countries. Mean birthweight increased with increasing education and was higher in married than in single mothers, and higher in ethnic Russians than in others. Survival in the perinatal period was substantially lower at all birthweights than in Sweden, which has the lowest neonatal mortality rate in Europe. There are wide inequalities in fetal development in Russia, especially in relation to maternal education, and the adverse outcomes appear to reflect a combination of adverse fetal development (implying the need for policies that improve the health of prospective mothers) and poor survival (implying the need for more effective care for newborn infants).
All forms of dementia including Alzheimer’s disease are currently incurable. Mitochondrial dysfunction and calcium alterations are shown to be involved in the mechanism of neurodegeneration in Alzheimer’s disease. Previously we have described the ability of compound Tg-2112x to protect neurons via sequestration of mitochondrial calcium uptake and we suggest that it can also be protective against neurodegeneration and development of dementia. Using primary co-culture neurons and astrocytes we studied the effect of Tg-2112x and its derivative Tg-2113x on β-amyloid-induced changes in calcium signal, mitochondrial membrane potential, mitochondrial calcium, and cell death. We have found that both compounds had no effect on β-amyloid or acetylcholine-induced calcium changes in the cytosol although Tg2113x, but not Tg2112x reduced glutamate-induced calcium signal. Both compounds were able to reduce mitochondrial calcium uptake and protected cells against β-amyloid-induced mitochondrial depolarization and cell death. Behavioral effects of Tg-2113x on learning and memory in fear conditioning were also studied in 3 mouse models of neurodegeneration: aged (16-month-old) C57Bl/6j mice, scopolamine-induced amnesia (3-month-old mice), and 9-month-old 5xFAD mice. It was found that Tg-2113x prevented age-, scopolamine- and cerebral amyloidosis-induced decrease in fear conditioning. In addition, Tg-2113x restored fear extinction of aged mice. Thus, reduction of the mitochondrial calcium uptake protects neurons and astrocytes against β-amyloid-induced cell death and contributes to protection against dementia of different ethology. These compounds could be used as background for the developing of a novel generation of disease-modifying neuroprotective agents.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
