Mineralogical and radiological studies on some Paleozoic yellow ochre deposits in Southwestern Sinai, Egypt.

Yellow ochre is the basic material used in the manufacture of yellow oxide (a commercial product). Yellow ochre samples were taken from three different formations in southwestern Sinai: Abu Hamata, Um Bogma, and Abu Zarab. Yellow ochre occasionally exists in Abu Hamata Formation particularly in El Ferah area, associated with Fe-Mn ore in Wadi El Sahu (Um Bogma Formation) and in Himayer area (Abu Zarab Formation).

Antimicrobial Potential of Different Isolates of Combined with Liquid Chromatography Tandem Mass Spectrometry Chemical Profiling.

The antimicrobial resistance of pathogenic microorganisms against commercial drugs has become a major problem worldwide. This study is the first of its kind to be carried out in Egypt to produce antimicrobial pharmaceuticals from isolated native taxa of the fungal , followed by a chemical investigation of the existing bioactive metabolites. Here, of the 155 clinical specimens in total, 100 pathogenic microbial isolates were found to be multi-drug resistant (MDR) bacteria.

Photocatalytic Activity of Revolutionary and 's Bio-Capped Silver Nanoparticles for Industrial Wastewater Treatment.

More suitable wastewater treatment schemes need to be developed to get rid of harmful dyes and pigments before they are discharged, primarily from apparel and textile factories, into water bodies. Silver nanoparticles (Ag-NPs) are very effective, reductive nanocatalysts that can degrade many organic dyes. In this study, Ag-NPs are stabilized and capped with bioactive compounds such as , , and from marine macroalgae extracts to produce Ag[GE], Ag[TE], and Ag[EE] NPs.

Navel orange peel hydroethanolic extract, naringin and naringenin have anti-diabetic potentials in type 2 diabetic rats.

The therapy of Type 2 Diabetes Mellitus (T2DM) stays a challenging issue. During the last decade, there has been an interest in the expansion of anti-diabetic drugs especially those of natural sources. Thus, the aim of this study was to assess the anti-hyperglycemic and the anti-hyperlipidemic effects as well as the anti-oxidant activities of navel orange hydroethanolic extract and its constituting flavonoids naringin and naringenin on nicotineamide (NA)/streptozotocin (STZ)-induced type 2 diabetic rats.

Neonatal and Maternal 25-OH Vitamin D Serum Levels in Neonates with Early-Onset Sepsis.

Vitamin D is a fat-soluble vitamin that is important for calcium metabolism and plays an important role in the immune functions. The aim of this study was to measure neonatal and maternal 25-OH vitamin D serum levels in neonates with early onset sepsis. The study included fifty neonates with early onset sepsis (25 full-term and 25 preterm infants) and thirty age and sex matched healthy neonates as controls.

The impact of dexmedetomidine infusion in sparing morphine consumption in off-pump coronary artery bypass grafting.

Purpose: Recovery from off-pump coronary artery bypass (OPCAB) has been reported to be more advantageous than conventional coronary artery bypass grafting with regard to both hospital and intensive care unit length of stay. Dexmedetomidine is a selective α-2 agonist that has been used successfully as an adjunct to narcotics in adult and pediatric cardiac surgery. The aim of this study was to assess the effect of dexmedetomidine on the recovery, total narcotic consumption, and total hospital and intensive care unit length of stay in patients undergoing OPCAB.

A comparative study between amiodarone and magnesium sulfate as antiarrhythmic agents for prophylaxis against atrial fibrillation following lobectomy.

Purpose: Atrial fibrillations are common after thoracic surgery. Amiodarone and magnesium sulfate have been used for the management of atrial fibrillation following cardiac and non-cardiac surgery. However, to our knowledge, comparisons of both drugs with each other and with a control group in relation to the prevention of AF following lung surgery have not been performed.

Safety of patient meals in 2 hospitals in Alexandria, Egypt before and after training of food handlers.

We assessed the food safety knowledge and food handling practices of 23 food handlers in 2 hospitals in Alexandria, Egypt [Gamal Abdel Nasser (GAN) and Medical Research Institute (MRI)] before and after a food safety training programme, and also the bacteriological quality of patient meals and kitchen equipment. There was a significant improvement in all knowledge-associated parameters except for personal hygiene in GAN. There was an improvement in the food safety practices in both hospitals.
