Synthesis and reactivity of monomeric magnesium and zinc silyl compounds To(M)M-Si(SiHMe2)3 and To(M)M-Si(SiMe3)3 are described (To(M) = tris(4,4-dimethyl-2-oxazolinyl)phenylborate). The magnesium compounds react slowly with water and air, while the zinc compounds are inert. With CO2, To(M)Mg-Si(SiHMe2)3 provides To(M)MgO2CSi(SiHMe2)3 through CO2 insertion, whereas To(M)Zn-Si(SiHMe2)3 affords T...

OBJECTIVE To describe the frequency of anemia and iron, zinc, copper and magnesium deficiencies among Mexican adolescents in the probabilistic survey ENSANUT 2006. MATERIALS AND METHODS The sample included 2447 adolescents aged 12 to 19 y. Capillary hemoglobin and venous blood samples were collected to measure the concentrations of ferritin, sTFR, CRP, zinc, iron, copper and magnesium. Logist...

C...

BACKGROUND Alopecia areata (AA) is a recurrent, nonscarring type of hair loss considered to be an autoimmune process. Though its etiopathology is not fully understood, there are claims that imbalance of trace elements may trigger the onset of AA. AIM The aim of the present study was to assess the levels of zinc, copper, and magnesium in the serum of AA patients. METHODS Fifty AA patients (3...

OBJECTIVE To present an overview of micronutrient status of Mexican children in 2006. MATERIALS AND METHODS Data on iron, zinc, folate and vitamin B12 deficiencies and low serum copper and magnesium were gathered and critically analyzed from the 2006 National Health and Nutrition Survey. RESULTS Iron deficiency is still the main nutritional deficiency in children (13%-26%). Zinc deficiency ...

BACKGROUND Some studies have linked colorectal cancer to metal exposure. AIMS Our objective was to evaluate the element distribution in colorectal adenocarcinoma biopsies, adjacent non-tumour tissues, and healthy controls. METHODS The study is a case-control study which compared the element distribution in colon biopsies from two groups of patients: with colorectal cancer (2 types of sample...

BACKGROUND In the present study, blood serum level of metals were determined in malarial patients and compared with those in the normal subjects without complication using Atomic Absorption Spectrometer. METHODS For the determination of these metals twelve intravenous blood samples each from referred malarial patients and a group of normal subjects were collected and immediately centrifuged t...

OBJECTIVE To describe the prevalence of serum iron and zinc deficiencies and low serum concentrations (LSC) of copper and magnesium in Mexican adults. MATERIALS AND METHODS Blood samples from subjects (≥20 years, both genders) participating in the 2006 National Health and Nutrition Survey were used to measure the serum concentrations of s-ferritin, soluble- transferrin-receptor (s-TfR), zinc,...

Article history: Received on: 03/09/2012 Revised on: 16/09/2012 Accepted on: 22/09/2012 Available online: 28/09/2012 Mechanism of action of both magnesium and zinc in mediating their antidepressant activities is supposed to be through NMDA receptor antagonism. In the background of similarity in mechanism of action of zinc and magnesium as antidepressant through antagonism of NMDA receptors and ...
