Herein, a Mn4+ ion doped complex ternary-alkaline fluoride red phosphor K2NaAlF6:Mn4+ has been synthesized through a facile two-step co-precipitation method at room temperature. The crystal structure, morphological properties and influence of the dopant concentration, temperature and humidity on luminescence properties as well as the performance of the as-synthesized phosphor used in white ligh...

BACKGROUND/AIMS Leukodystrophies due to abnormal production of myelin cause extensive morbidity in early life; their genetic background is still largely unknown. We aimed at reaching a molecular diagnosis in Ashkenazi-Jewish patients who suffered from developmental regression at 6-13 months, leukodystrophy and peripheral neuropathy. METHODS Exome analysis, determination of alkaline ceramidase...

The interaction of Ti(IV) with 4-(2',3',4'-trihydroxyphenyl)-2-nitro-1-sulfoazobenzene (H3L) in the presence and absence cationic surfactants (CAS) (cetylpyridinium chloride (CPCl), cetylpyridinium bromide (CPBr), cetyltrimethylammonium (CTMABr)) was studied. interval concentration obeying Beer's law is established. In complex formation titanium(IV), dependence A = f(C) expressed by linear equa...

A precise and reproducible method is described for the ultramicro fluorimetric determination of calcium in plasma, based upon the formation of a fluorescent complex between calcium and calcein at a strongly alkaline pH. In a group of normal subjects, the mean concentration of plasma calcium was 9.66 mg/100 ml with a normal range of 8.9 to 10.4 mg/100 ml.

Pollen tubes grow by spatially and temporally regulated expansion of new material secreted into the cell wall at the tip of the tube. A complex web of interactions among cellular components, ions and small molecule provides dynamic control of localized expansion and secretion. Cross-correlation studies on oscillating lily (Lilium formosanum Wallace) pollen tubes showed that an increase in intra...

Neutral lipolytic activity (hydrolysis of olive oil at 37”, pH 7.0) and alkaline lipolytic activity (hydrolysis of tributyrin at 47’, pH 8.0) have previously been demonstrated in human adipose tissue. Neutral lipolytic activity has currently been shown to be present in a large molecular weight substance, associated with lipid, and separable from most alkaline lipolytic activity by ammonium sulf...

The liver is one of the organs involved in the multiorgan failure that occurs in sickle cell disease, the pathophysiology of liver disease in this condition is complex because of the interrelated multifactorial causes. Liver dysfunction was assessed in both paediatric and adult sickle cell disease patients in the steady state. The transaminases and alkaline phosphatase were analysed by automati...

Eudialyte-group minerals are important accessory of peralkaline rocks nepheline-syenite massifs and alkaline–ultramafic complexes. Here, we report the complex study a eudialyte-group mineral (EGM) from pegmatite alkaline-ultrabasic Odikhincha massif (Polar Siberia). The chemical composition studied EGM is intermediate between those taseqite eudialyte, with small admixtures other members eudialy...

Alkaline phosphatase, the phoA product, is synthesized constitutively in phoR mutants. This constitutive synthesis, which is independent of phosphate control, varies with changes in the osmolarity of the growth medium; phoA expression increases with increasing osmolarity. Maximum expression of the osmoregulated genes phoA, ompC, and ompF was achieved by osmotic manipulation of minimal medium; c...
