A relationship has been reported between trace elements and diabetes mellitus. This study evaluated the role of such a relationship in 83 patients with non-insulin dependent diabetes mellitus (40 men and 43 women), with a mean duration of diabetes of 3.9 +/- 3.6 years. Patients with nephropathy were excluded. Thirty healthy non-diabetic subjects were studied for comparative analysis. Subjects w...

The first sodium-magnesium and sodium-zinc ketimido complexes display contrasting inverse crown ring and pseudo-cubane structures respectively, while a sodium-zinc heterotrianionic alkide-alkoxide-amide adopts a third type of structure with a stepped ladder motif.

INVESTIGATION OF THE INFLUENCE ZINC OXID CONTENT AND SCAFFOLD MORPHOLOGY ON MECHANICAL PROPERTIES POLY(ε-CAPROLACTONE) / OXIDE NANOCAMPOSITE SCAFFOLDS

postpartum depression (ppd) is a major depressive disorder that most often emerges within 6 to 12 weeks of delivery, but can happen any time up to 1 year after birth. in developed countries, the incidence of postnatal depression is about 10-15% in adult women depending upon the diagnostic criteria, timing of screening and screening instruments used. mothers with depressive symptoms have been fo...

BACKGROUND Although the exact pathophysiology of preeclampsia is not fully understood, several elemental micronutrient abnormalities have been suggested to play a contributory role in preeclampsia. AIMS To investigate the levels of calcium, magnesium, zinc and copper in women with preeclampsia. SUBJECTS AND METHODS A case-control study was conducted in Omdurman Maternity Hospital, Sudan, du...

Magnesium alloys are a strong candidate for various applications in automobile and aerospace industries due to their low density specific strength. Micro-alloying magnesium with zinc, yttrium, cerium enhances mechanical properties of through grain refinement precipitation hardening. In this work, critical review magnesium-based binary systems including Mg-Zn, Mg-Y, Mg-Ce, Zn-Y, Zn-Ce is present...

Much attention has been focused on the biomedical applications of magnesium phosphate cement (MPC) as bone substitution material. The use of porous scaffolds with characteristics such as high porosity along with macropores and three-dimensional interconnected pore structures is beneficial for repairing bone defects. MPC has been proven to be degradable and biocompatible, and therefore might be ...

The enzyme (-) S-adenosyl-L-methionine-magnesium protoporphyrin methyltransferase, which catalyzes the transfer of the methyl group from (-) S-adenosyl-L-methionine to magnesium protoporphyrin to form magnesium protoporphyrin monomethyl ester, has been detected in chloroplasts isolated from Zea mays. Zinc protoporphyrin and free protoporphyrin also act as substrates in the system, although neit...

Water samples from the western basin of Lake Erie were filtered to restrain suspended particles larger than 4 /xm and were analyzed for copper, iron, zinc, manganese, magnesium, and calcium by atomic absorption spectrophotometry. Samples were collected at weekly intervals during July-August and with less frequency in September, October and November (1970). Mean seasonal and range of concentrati...

2 1. Introduction Photochemistry of the porphyrins and their relatives has been largely inspired by photosynthetic processes in nature. As a result of this, most current studies generally utilize the chemistry of magnesium and zinc porphyrin analogues. Especially, magnesium tetrapyrrole chelates, i.e. magnesium porphyrins and phthalocyanines have found wide interest. This is primarily related t...
