Vesicles derived from maize roots retain a membrane-bound H+-ATPase that is able to pump H+ at the expense of ATP hydrolysis. The H+ pumping and the ATPase activity of these vesicles are inhibited by lithium fluoride and by the complex formed between fluoride and aluminum. The inhibition promoted by lithium fluoride increases as the MgCI, concentration in the medium is increased from 2 to 20 mM...

Background & Aims: The topical anesthetic effects of diphenhydramine combined with ingredients such as aluminum and magnesium hydroxide have been used for many years in modern medicine. Due to the limited durability of anesthetic mouthwashes due to saliva secretion and the spreading use of herbal and natural medicines in pharmacotherapy, this study was designed to formulate diphenhydramine in t...

haemorrhagic septicaemia (hs) vaccine which is prepared in razi institute is used in endemic areas ofiran. aluminum-hydroxide gel was used as adjuvant for preparing this vaccine. post-vaccinal shock reactionswere the main complaint after use of this vaccine. in a previous study, we could improve the vaccine byalum-precipitation pasteurella multocida cells and removing the liquid phase. in this ...

The process of hydrogen formation and the associated risk combustion explosion is a complex problem concerned with radiation safety nuclear reactors. Lithium, potassium sodium hydroxides are used in VVER reactors as corrective additives for keeping potential water coolant boric acid at controlled level 5.8 to 10.3. In investigating interaction aqueous solutions above aluminum, most chemically a...

9,10-Dibromo-anthracene was lithiated once or twice, and the products were reacted with different sulfurdiimides. The reactions yielded [(THF)2Li(NBu)2SAnBr] (1), [(Et2O)(LiBr)Li(NBu)2SAnBr]2 (2), [Me2Al(NBu)2SAnBr] (3), [{(THF)2Li(NR)2S}2An] (4: R = tBu; 5: R = SiMe3) and [{Me2Al(NSiMe3)2S}2An] (6). All products were fully characterized by X-ray structure analysis, elemental analysis, NMR and ...

The methods commonly used for precipitating aluminum by 8-hydroxyquinoline from an acetic-acid solution, buffered with ammonium acetate, do not sufficiently define the conditions requisite for complete precipitation. The present article describes a method in which aluminum is precipitated as the oxyquinolate from a solution which has been partially neutralized with ammonium hydroxide, using bro...

chemical wastewater treatment is one of the attracting and common methods for wastewater treatment among the currently employed chemical unit processes. the use of coagulant-flocculant compound is one of the efficient methods for separating of paint and recovery of water. in this research, it was introduced and the effect of ph on removal of solid content from solution was studied experimentall...

The IgE production was compared in the presence and absence of aluminum hydroxide gel (alum). Without alum, the IgE production was induced within a suitable range of the antigen dosage; however, alum enhanced it. Alum did not affect the minimum requirement for the antigen dosage, indicating that alum may not take part in the efficiency of antigen presentation.
