We evaluated the role of early life factors in a large, population-based, case-control study of breast cancer risk in postmenopausal women. Case women in Massachusetts, New Hampshire, and Wisconsin were ascertained through state cancer registries; control women were randomly selected from drivers license lists (50–65 years of age) or Medicare beneficiary lists (65–79 years of age). Information ...

aim &background;: muslims fast from sunrise to sunset during ramadan, the 9th lunar month. the duration of fasting varies from 13 to 18 hrs per day. fasting individuals abstain from drinking liquids and eating foods. manypregnant women and gynecologists are concerned about the possible complicationsassociated with fasting and effects on fetal health. the aim of this study was to determine the e...

background: increased requirement and decreased dietary intakes of micronutrients during pregnancy might affect maternal health and pregnancy outcomes. this study was aimed to examine the effects of two types of multiple micronutrient supplementations on pregnancy outcomes in kashan, iran. methods: in a randomized single‑blind controlled clinical trial, 104 primigravid singleton pregnant women ...

Abstract Background Globally, infant mortality has declined considerably but remained unacceptably high in sub-Saharan Africa, especially Nigeria where rate is 67/1000 live births. To facilitate reduction Nigeria, an understanding of the synergistic effect bio-demographic characteristics mothers known as High Risk Birth Behaviours (HrBBs) important. We therefore investigated influence HrBBs on ...

Significance We followed a population-representative cohort of children from birth to their mid-forties. As adults, with better self-control aged more slowly in bodies; showed fewer signs brain aging; and were equipped manage later-life health, financial, social demands. The effects children’s separable socioeconomic origins intelligence. Children changed rank order across age, suggesting the h...

Let M be a tropical matrix (k + x) × (k + x ′) for some k, x , x ′ ∈ N − {0} with tropical rank k. We show that Kapranov rank is k too if x and x ′ are not too big; namely if we are in one of the following cases: a) k ≥ 6 and x , x ′ ≤ 2 b) k = 4, 5, x ≤ 2 and x ′ ≤ 3 (or obviuosly the converse, that is x ≤ 3 and x ′ ≤ 2) c) k = 3 and either x , x ′ ≤ 3 or x ≤ 2 and x ′ ≤ 4 (or obviuosly the co...

We investigate relations between different width parameters of graphs, in particular balanced separator number, treewidth, and cycle rank. Our main result states that a graph with balanced separator number k has treewidth at least k but cycle rank at most k · ( 1 + log nk ) , thus refining the previously known bounds, as stated by Robertson and Seymour (1986) and by Bodlaender et al. (1995). Fu...
