Abstract The room temperature compression experiments of as-extruded AZ31 magnesium alloy under different loading speeds were carried out on a universal tensile testing machine. fracture failure characteristics and mechanism the analyzed by scanning electron microscope (SEM) optical (OM). results show that during test, crushed sample has certain pier coarseness, macro is located at one third sa...

Magnesium sulfate is widely used in obstetrics and is drug of choice in two important complications of pregnancy, preeclampsia and preterm labor. The antagonistic effects of magnesium sulfate on calcium ion and on platelet aggregation may lead to changes in bleeding time. This study was conducted to evaluate the effect of magnesium sulfate on bleeding time in women with threatened preterm labor...

to study the role of preoperative intravenous magnesium sulphate in decreasing post-cesarean pain and opioid requirement during first 24hrs.in a double blind randomized clinical trial, prior to induction of general anesthesia, fifty elective cesarean candidates were randomly assigned to one of the two groups of placebo or magnesium sulfate. after surgery visual analogue scale (vas) and infused ...

Magnesium orthopaedic fracture fixation devices can potentially provide significant clinical benefits, such as the elimination of secondary surgeries for device removal due to in-vivo resorption and reduced stress shielding stiffness. However, development, approval, adoption magnesium has been hindered by excessively high rates corrosion that structural integrity be catastrophically before heal...

BACKGROUND Magnesium plays a role in glucose and insulin homeostasis and evidence suggests that magnesium intake is associated with insulin resistance (IR). However, data is inconsistent and most studies have not adequately controlled for critical confounding factors. OBJECTIVE The study investigated the association between magnesium intake and IR in normal-weight (NW), overweight (OW) and ob...

Magnetic magnesium alloys can be utilised as a load sensitive material, in which the inverse magnetostrictive effect is used in order to measure the actual loads in structural components manufactured from such lightweight sensor alloys. To achieve a material which exhibits magnetic properties, magnesium is alloyed with ferromagnetic materials like cobalt or samarium-cobalt. In order to improve ...
