vinelanidii. The related compounds tested, phenoxyacetic acid, phenylpropionic acid, orthoand parachlorophenoxyacetic acids, inhibited the test organism to lesser degrees. Protection from the inhibition produced by 2 x 10-2 MI phenoxyacetic acid and phenylpropionic acid was afforded by molar ratios of 1: 1 and 2: 1 respectively', magnesium to the agents. Considerable protection, though not comp...

Magnesium is one of the most essential mineral in the human body, connected with brain biochemistry and the fluidity of neuronal membrane. A variety of neuromuscular and psychiatric symptoms, including different types of depression, was observed in magnesium deficiency. Plasma/serum magnesium levels do not seem to be the appropriate indicators of depressive disorders, since ambiguous outcomes, ...

BACKGROUND Magnesium ion is critical for life and is integrally involved in cellular function and a key component of normal bone mineral. In health, the kidneys, gastrointestinal tract and bone are responsible for maintaining serum magnesium concentrations in the normal range and magnesium balance. Most clinical disorders involving magnesium, other than chronic kidney disease (CKD), result in h...

In an earlier, rather extensive, publication in this journal on the "Functional Pathology of Hyperparathyroidism " (1) no mention wasmade of magnesium metabolism. Data have now been collected permitting a contribution to this phase of the subject. The methods of study were the same as described in the previous paper (1). Magnesium determinations were made by the procedure outlined by Briggs (2)...

The mineralization of 1.0 to 100 ng each of four complexing compounds-oxalate, citrate, nitrilotriacetate (NTA), and EDTA-per ml was tested in media prepared in accordance with equilibrium calculations by a computer program so that the H, Ca, Mg, Fe, or Al complex (chemical species) was predominant. Sewage microorganisms mineralized calcium citrate more rapidly than iron, aluminum, or hydrogen ...

Magnesium slag is a valuable resource when proper disposal and utilization are adopted. The main pollution of magnesium caused dust fluorine pollution. Formation mechanism fine investicated. Alike steel slag, phase transition dicalcium silicate in around 500 °C brings volume expansion, which causes the disintegration powdering slag. Chamical stabilization experiments were carried out. effects p...

Both compounds have become more commonly used in dietary supplements. Stearic acid is commonly used as a binder in tablets, and it has lubricant properties. Magnesium stearate is a lubricant commonly used in tablet formulations. After achieving a homogenous blend of powdered ingredients, adding a small amount of magnesium stearate enables the powder blend particle surface to be sufficiently coa...

A new protocol for synthesizing different functionalized isoxazoles is provided. Carbamoylnitrile oxide generated from nitroisoxazolone underwent inverse electron-demand 1,3-dipolar cycloaddition with 1,3-dicarbonyl compounds in the presence of magnesium acetate that formed magnesium enolate in situ. Although electron-deficient trifluoroacetoacetate did not undergo this cycloaddition under the ...

Dehydrocoupling reactions between the boranes HBpin and 9-borabicyclo[3.3.1]nonane and a range of amines and anilines ensue under very mild reaction conditions in the presence of a simple β-diketiminato magnesium n-butyl precatalyst. The facility of the reactions is suggested to be a function of the Lewis acidity of the borane substrate, and is dictated by resultant pre-equilibria between, and ...

It is suggested that under physiological conditions (> 1 mM Mg(2+)) MgATP binds to myosin to form a chelate involving the two reactive sulfhydryl sites (SH(1) and SH(2)). The stability of the chelate structure results in marked inhibition of the myosin ATPase in the presence of millimolar magnesium ion. The inhibitory effect of magnesium ion can be eliminated chemically by blocking either the S...
