Fruit yield decreases gradually after several years of cultivation in Amomum villosum, an important Chinese medicinal herb, which is generally attributed to plant senescence. However, the reasons for plant senescence are still not clear until now. In this study, we investigated the effects of micronutrient deficiencies on leaf senescence. We hypothesized that micronutrient deficiencies may caus...

chromosomal defects are relatively frequent in infertile men however, translocations between the y chromosome and autosomes are rare and less than 40 cases of y-autosome translocation have been reported. in particular, only three individuals has been described with a y;21 translocation, up to now. we report on an additional case of an infertile man in whom a y;21 translocation was associated wi...

the short arm of rye (secale cereale l.) chromosome 1 (1rs), besides being part of the rye genome, is present in many hundred wheat cultivars as either 1rs.1bl or 1rs.1dl wheat-rye translocation. in this study, the distribution of the wheat–rye translocation was examined in 33 iranian winter and spring wheat cultivars, nine of which had a known donor of 1rs.1bl translocation and the other 24 we...

Micronutrient malnutrition remains a problem of public health concern in most developing countries, partly due to monotonous, cereal-based diets that lack diversity. The study objective was to assess whether dietary diversity score (DDS) based on a simple count of food groups consumed and DDS using a 10-g minimum intake for each food group (DDS 10g) are good indicators of adequate micronutrient...

BACKGROUND Few studies have considered source-specific micronutrient intake in relation to mortality under the consideration that dietary and supplemental intake could exhibit different effects. OBJECTIVE To evaluate the association between intake of vitamin C, E, folate, beta-carotene from diet and supplements, and overall mortality. Furthermore, to examine effect modification by smoking, al...

BACKGROUND To explore the relation between micronutrient status and health, it is important to understand which markers of micronutrient status can be relied on and under what circumstances. OBJECTIVE The objective of this article was to develop a common systematic review methodology for use in the assessment of micronutrient status for selenium, iodine, copper, zinc, riboflavin, vitamin B-12...

OBJECTIVE We investigated the relationship of micronutrient deficiencies with the frailty syndrome in older women living in the community. METHODS Frailty status and serum micronutrients were assessed in a cross-sectional study of 754 women, 70-80 years old, from the Women's Health and Aging Studies I and II. RESULTS Among nonfrail, prefrail, and frail women, respectively, geometric mean se...
