BACKGROUND The use of conventional breeding techniques and biotechnology to improve the micronutrient quality of staple crops is a new strategy to address micronutrient deficiencies in developing countries. This strategy, referred to as "biofortification," is being developed and implemented through the international alliance of HarvestPlus to improve iron, zinc, and vitamin A status in low-inco...

The present literature review examines the following questions: (a) What is the evidence that micronutrient requirements are increased in physically active people? (b) Is there an association between physical activity and micronutrient intake? (c) Are there any significant differences between indices of micronutrient status between physically active and inactive people? The available data sugge...

Copper is involved in a number of metabolic reactions that ensure the vital activity plants; therefore, its deficiency leads to disruption physiological processes and decrease productivity. In order increase contentof cupper plants, searching for ways provide better absorption copper by roots enhance transport aboveground organs.The use growth regulators these purposes, including salicylic acid...

down’s syndrome, or 21 trisomy, is the most common autosomal abnormality, with incidence of 1 per 815 live births in iran. worldwide reports indicate that about 95% are regular trisomy, or nondisjunction, 1% are mosaic and 4% due to translocation. however, these values show a geographical variation. a cytogenetic study of down's syndrome, or trismoy 21, was carried out on 366 cases (202 males a...

BACKGROUND The effects of prenatal food and micronutrient supplementation on maternal micronutrient status are not well known. OBJECTIVE We compared the efficacy and effectiveness of 3 different micronutrient supplements on maternal micronutrient status when combined with food supplementation. METHODS In the MINIMat (Maternal and Infant Nutrition Intervention, Matlab) trial in Bangladesh, 4...

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...

background: acute lymphoblastic leukemia (all) is the most common form of childhood cancer leading to cancer-related death in children. most infants with all harbor recurring structural chromosomal rearrangements that are important initiating events in leukemogenesis but are insufficient to explain the biology and heterogeneity of the disease. mixed-lineage leukemia-rearrangement (mll-rearrange...

Introduction: Intellectual disability or intellectual retardation is a condition in which total mental functioning is distinctively below average and there are disabilities in adaptive behaviors during growth. According to the definition of American Mental Disability Community in 1992 a person is considered intellectually disabled if he or she has an IQ (intelligence quotient) of less than 70...

Micronutrient deficiencies have been found in obese individuals across age groups worldwide. While the effects of micronutrient deficiencies on human functions have been studied widely in different populations, there is limited information on how these micronutrient deficiencies affect obese populations. An examination of the available literature suggests associations exist between micronutrien...

BACKGROUND The prevalence of micronutrient deficiencies is higher in obese individuals compared to normal-weight people, probably because of inadequate eating habits but also due to increased demands among overweight persons, which are underestimated by dietary reference intakes (DRI) intended for the general population. We therefore evaluated the dietary micronutrient intake in obese individua...
