Evaluation of Trace Metal Content by ICP-MS Using Closed Vessel Microwave Digestion in Fresh Water Fish
The objective of the present study was to investigate trace metal levels of different varieties of fresh water fish using Inductively Coupled Plasma Mass Spectrophotometer after microwave digestion (MD-ICPMS). Fish samples were collected from the outlets of twin cities of Hyderabad and Secunderabad. The trace metal content in different varieties of analyzed fish were ranged from 0.24 to 1.68 mg/kg for Chromium in Cyprinus carpio and Masto symbollon, 0.20 to 7.52 mg/kg for Manganese in Labeo rohita and Masto symbollon, 0.006 to 0.07 mg/kg for Cobalt in Rastrelliger kanagurta and Pampus argenteus, 0.31 to 2.24 mg/kg for Copper in Labeo rohita and Penaeus monodon, 3.25 to 14.56 mg/kg for Zinc in Cyprinus carpio and Macrobrachium rosenbergii, and 0.01 to 2.05 mg/kg for Selenium in Rastrelliger kanagurta and Pampus argenteus, respectively. Proximate composition data for the different fishes were also tabulated. Since the available data for different trace elements for fish is scanty, here an effort is made to present a precise data for the same as estimated on ICP-MS. Results were in accordance with recommended daily intake allowance by WHO/FAO

Nutritionally Enhanced Staple Food Crops
Crop biofortification is a sustainable and cost-effective strategy to address
malnutrition in developing countries. This review synthesizes the progress
toward developing seed micronutrient-dense cereals and legumes cultivars by
exploiting natural genetic variation using conventional breeding and/or transgenic
technology, and discusses the associated issues to strengthen crop biofortification
research and development. Some major QTL for seed iron and zinc,
seed phosphorus, and seed phytate in common bean, rice,J;md wheat have been
mapped. An iron reductase QTL associated with seed-iron ~QTL is found in common bean where the genes coding for candidate enzymes involved in phytic
acid synthesis have also been mapped. Candidate genes for Ipa co segregate with
mutant phenotypes identified in rice and soybean. The Gpe-B1 locus in wild
emmer wheat accelerates senescence and increases nutrient remobilization
from leaves to developing seeds, and another gene named TtNAM-B1 affecting
these traits has been cloned. Seed iron-dense common bean and rice in Latin
America; seed iron-dense common bean in eastern and southern Africa;....
