We report a new single-reagent colorimetric assay for the determination of calcium in serum. The assay is based on a novel chromogenic tetracarboxylic acid chelating agent. The method has several advantages over the o-cresolphthalein complexone (CPC) method, including improved linearity, better accuracy, increased stability, and lower working pH (9.0). The calibration curve for the assay is lin...

It is obvious that lead intake is of concern not for its beneficial/essential effects on metabolism, but rather for its toxic actions, which can be especially damaging to children. The objective of this study was to analyze the concentration of lead in milk of mothers during prolonged lactation. Milk samples from 43 mothers were collected at 2 months postpartum. Lead was analyzed using atomic a...

We evaluated the effect of cadmium (Cd) on the structure and function of the head kidney in the freshwater fish Colossoma macropomum (C. macropomum). Juveniles were exposed to 0.1 mg/L CdCl2 for 31 days. Blood samples were examined using hematological tests and head kidney histology was determined by light microscopy. The concentration of Cd in the head and trunk kidneys was measured using an a...

Spices and herbs are being used as a diet ingredient often to improve color, aroma and acceptability of food. The contamination of spices with heavy metals may result in the accumulation of these metals in the body organs. The aim of the present study was to investigate As, Cu, Fe and Zn contents in the most popular spices and herbs that are used in Egyptian cuisine. Ten samples were purchased ...

AIM This study evaluated serum levels of zinc in patient with CD compare to healthy subjects. BACKGROUND Celiac disease (CD) is characterized by small intestinal malabsorption of nutrients as a consequence of ingestion of wheat gluten. Zinc is an essential trace element that it has vital biological functions. PATIENTS AND METHODS Sera of 30 celiac cases and 30 healthy normal cohorts as cont...

The exposure of human to toxic heavy metal release from plastic container creates a major health hazards. The main objectives of this study was to examine the concentration of toxic heavy metals (Pb, Cu, Ni, Zn, Mn, Cr and Cd) in local made food containers purchased from various districts of U.P,(India), at 25±2°C for 24hrs in different simulating solvents as per BIS, IP, USP and other guidelin...

To determine the impact of socioeconomic status on plasma trace element status and pregnancy outcomes, 349 pregnant women, aged 15-40 years (mean 27.04 +/- 2.75 years), recruited at < or = 25 weeks (mean 21.76 +/- 3.12 weeks) gestational age, were followed up till delivery during which maternal and foetal outcomes were recorded. Plasma copper, iron, and zinc were determined using atomic absorpt...

Archaeologists have long noted the striking monumentality and large-scale efforts behind the Iron Age hilltop settlements. Yet, because of limited excavations, they represent a controversial part of the Migration Period society and much of their function remains hidden. This paper deals with questions concerning the inner organization and activities that took place within the Iron Age hilltop s...

Objective Trace metals are required in minute amounts for normal human growth and physiological function of the body and might play a vital role in the pregnancy and outcome. The study was conducted to assess the role of trace metals zinc (Zn) and copper (Cu) among women with history of spontaneous abortion (SAb Cases) with respect to women without such history (Controls). MaterialsAndMethods A...

Groundwater is the main source of water for domestic use in Nigeria because it is perceived to be clean. The presence of geogenic contaminants (arsenic and fluoride), and the level of awareness of their presence in groundwater in Ibadan, Nigeria was examined in this study. A total of one hundred and twenty groundwater samples were collected from hand dug wells which tap into shallow aquifers an...
