While the societal relevance of space physics drives most research in field, this paper argues for merit addressing problems that are core to plasma physics, regardless discipline or application society. The geospace environment is a unique, naturally occurring laboratory can be used investigating basic processes. Ground and satellite-based observations provide important data understanding proc...

The present study examined differences in olfactory sensitivity between 16 naturally cycling (NC) women and 17 women taking monophasic oral contraceptives (OCs) to six odors: lemon, peppermint, rose, musk, androstenone and androsterone. Thresholds were assessed twice for both groups of women (during the periovulatory and luteal phases of their cycles) via a forced-choice discrimination task. NC...

Background: Total folate intake includes naturally occurring food folate and folic acid from fortified foods and dietary supplements. Recent reports have focused on total folate intakes of persons aged 14 y. Information on total folate intakes of young children, however, is limited. Objective: The objective was to compute total folate and total folic acid intakes of US children aged 1–13 y by u...

The vitamin folate is recognized as beneficial health-wise in the prevention of neural tube defects, anemia, cardiovascular diseases, poor cognitive performance, and some forms of cancer. However, suboptimal dietary folate intake has been reported in a number of countries. Several national health authorities have therefore introduced mandatory food fortification with synthetic folic acid, which...

Marine mammals being among the top predators in the food web tend to accumulate organic and inorganic contaminants from the environment. The body burden of contaminants in these species could reflect their foods and thus contaminant levels could serve as proxies on the changes of ecosystem. A pilot study was carried out to investigate the possibility of radionuclide leakage at Amchitka using a ...

BACKGROUND AND OBJECTIVE Nutrient values are influenced by the analytical method used. Food folate measured by high performance liquid chromatography (HPLC) or by microbiological assay (MA) yield different results, with in general higher results from MA than from HPLC. This leads to the question of how to deal with different analytical methods in compiling standardised and internationally compa...
