Plackett-Burman design and Box-Behnken response surface methodology (RSM) was employed to optimize the medium components for the chitin deacetylase (CDA) activity from Bacillus amyloliquefaciens Z7. Plackett-Burman design was applied to determine the specific medium components affecting CDA activity and found that starch, chitin and MgSO4 were critical in augmenting CDA activity. These signific...

AIM This research was carried out to compare magnesium sulfate (MgSO4) with isotonic saline in terms of pain control after herniorrhaphy. PATIENTS & METHODS A randomized double-blind study, in which the patients were blind to all. A total of 100 patients who were candidates of herniorrhaphy were randomized into two groups: experimental and control (50 patients in each). Anesthesia was induced...

OBJECTIVES Febrile seizures (FS) are the most common type of convulsive events among children. Its prevalence has been estimated to be 2-5% in children between 3 months and 5 years old. Also, blood and CSF magnesium levels have been demonstrated to be reduced in children with FS. This study investigates the effect of MgSo4 pretreatment on the behaviors caused by hyperthermia (HT) and effect of ...

OBJECTIVE Evaluation of the efficacy of nebulized magnesium sulfate (MgSO4) alone and in combination with salbutamol in acute asthma. METHODS A double-blind randomized controlled study was conducted in Chest and Emergency Departments. Thirty patients of acute attack of bronchial asthma were randomized into three groups: MgSO4 nebulization (group A), salbutamol nebulization (group B), and thei...

One-dimensional magnesium oxysulfate 5Mg(OH)2 MgSO4 3H2O (abbreviated as 513MOS) with high aspect ratio has attracted much attention because of its distinctive properties from those of the conventional bulk materials. 513MOS nanowires with different morphologies were formed by varying the mixing ways of MgSO4 7H2O and NH4OH solutions at room temperature followed by hydrothermal treatment of the...

BACKGROUND The pharmacokinetic basis of magnesium sulphate (MgSO4 ) dosing regimens for eclampsia prophylaxis and treatment is not clearly established. OBJECTIVES To review available data on clinical pharmacokinetic properties of MgSO4 when used for women with pre-eclampsia and/or eclampsia. SEARCH STRATEGY MEDLINE, EMBASE, CINAHL, POPLINE, Global Health Library and reference lists of eligi...

Twelve consecutive patients who developed torsade de pointes (polymorphous ventricular tachycardia with marked QT prolongation, TdP) over a 4 year period were treated with intravenous injections of magnesium sulfate. In nine of the patients a single bolus of 2 g completely abolished the TdP within 1 to 5 min, and in three others complete abolition of the TdP was achieved after a second bolus wa...

The present study was carried out to optimize some culture conditions increase lipid production from Yarrowia lipolytica B9 in crude glycerol-based medium. experiments displayed that too high concentrations of ammonium sulfate, KH2PO4, and MgSO4 increased cell growth but inhibited synthesis. In contrast, more synthesis lipids determined be achived at NaCl. optimum glycerol, MgSO4, NaCl for were...

Required revisions:  The abstract includes a clear statement supporting the need for MgSO4 for women at risk of very preterm birth to reduce the likelihood of cerebral palsy in the child, a brief description of the study design, methods, KT strategies used, the primary outcome, key results and conclusions of this project.  Recommendations: (a). Include a statement describing the extent of the...

BACKGROUND Alterations in gastrointestinal motility and hormone secretion, especially activation of the ileal brake, have been documented in malabsorption. AIM To investigate whether artificially-induced accelerated small intestinal transit activates the ileal brake mechanism. METHODS Eight healthy volunteers (four female, four male; age 21 +/- 3 years) participated in four experiments: (a)...
