Decreased fruit and vegetable consumption, along with elevated blood cadmium concentrations, are frequently observed among cigarette smokers. Few studies have investigated whether the blood cadmium concentrations of cigarette smokers are associated with the consumption of antioxidative nutrients, as well as foods containing high concentrations of(More)
The goal of the present study is to unveil the gene expression profile specific to the biological processes of human breast epithelial cell invasion and migration using an MCF10A model genetically engineered to constitutively activate the H-ras or N-ras signaling pathway. We previously showed that H-Ras, but not N-Ras, induces MCF10A cell(More)
Elevated homocysteine (Hcy) levels have been associated with an increased risk of cognitive impairment and Alzheimer's disease (AD). Tissue factor pathway inhibitor (TFPI) has recently emerged as a candidate marker of endothelial damage in AD. We investigated the relationship between plasma levels of folate, vitamin B12, Hcy, and TFPI, as well as cognitive(More)
BACKGROUND It is possible that blood B vitamins level and cognitive function may be affected by dietary intake of these vitamins, no study however has yet been conducted on relationships between B vitamins intake and cognitive function among elderly population in Korea. This study examined the relationship between B vitamins intake and cognitive function(More)
Cells surviving crisis are often tumorigenic and their telomeres are commonly maintained through the reactivation of telomerase. However, surviving cells occasionally activate a recombination-based mechanism called alternative lengthening of telomeres (ALT). Here we establish stably maintained survivors in telomerase-deleted Caenorhabditis elegans that(More)
Excessive iron consumption during pregnancy can lead to increased oxidative stress in the maternal body, which may result in adverse pregnancy outcomes. Glutathione S-transferases (GSTs) originate from a superfamily of detoxifying enzymes that play a role in reducing xenobiotic compounds and oxidative stress. The aim of this study was to determine the(More)
OBJECTIVE To evaluate the relation between maternal serum folate status and blood mercury in pregnant Korean women. METHODS The nutritional status of folate and the blood mercury concentration were measured in pregnant Korean women who participated in a multicenter prospective study from 2006 through 2011. We analyzed existing blood mercury data based on(More)
BACKGROUND Iron supplementation is a common recommendation for pregnant women to prevent iron deficiency during pregnancy. There is an increasing concern about excessive iron consumption as a general iron prophylaxis by pregnant women without any due consideration about their dietary iron intake or iron status. Our present study investigated the association(More)
This paper describes some of the results of a probe study where members of three-generational families, where at least one person is geographically separated from the others, talk about their emotional experiences. The method for eliciting this information is briefly described along with some of the themes identified in a grounded theory analysis. These(More)
The roles of sir-2.1 in C. elegans lifespan extension have been subjects of recent public and academic debates. We applied an efficient workflow for in vivo(13)C-labeling of C. elegans and (13)C-heteronuclear NMR metabolomics to characterizing the metabolic phenotypes of the sir-2.1 mutant. Our method delivered sensitivity 2 orders of magnitude higher than(More)
