Characterization of adsorption of aqueous arsenite and arsenate onto charred dolomite in microcolumn systems.

In this work, the removal of arsenite, As(III), and arsenate, As(V), from aqueous solutions onto thermally processed dolomite (charred dolomite) via microcolumn was evaluated. The effects of mass of adsorbent (0.5-2 g), initial arsenic concentration (50-2000 ppb) and particle size (<0.

Assessment of antifungal activity of herbal and conventional toothpastes against clinical isolates of Candida albicans.

Objective: To detect the anticandidal activity of nine toothpastes containing sodium fluoride, sodium monofluorophosphate and herbal extracts as an active ingredients against 45 oral and non oral Candida albicans (C. albicans) isolates.

Methods: The antifungal activity of these toothpaste formulations was determined using a standard agar well diffusion method.

Molecular analysis and susceptibility patterns of methicillin-resistant Staphylococcus aureus strains causing community- and health care-associated infections in the northern region of Palestine.

Background: Community acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) is a major global problem. This study attempted to investigate the prevalence of nasal carriage of Staphylococcus aureus and methicillin-resistant Staphylococcus aureus (MRSA) strains among 360 healthy university students at An-Najah National University, Palestine. For the purpose of comparing the staphylococcal cassette chromosome methicillin resistant determinant (SCCmec) type of MRSA, 46 clinical MRSA isolates were also included in this study.

Effect of ethanolic extract of Ecballium elaterium against Staphylococcus aureus and Candida albicans.

Objective: To evaluate the antimicrobial activity of ethanolic extract of Ecballium elaterium (E. elaterium) fruits alone against Staphylococcus aureus (S. aureus) strains and Candida albicans (C.

Full-thickness skin necrosis after arginine extravasation--a case report and review of literature.

The arginine test is highly useful in the evaluation of short-stature children and adolescents. Extravasation of arginine can cause full-thickness skin necrosis that requires serious surgical intervention with aesthetic and functional sequellea. The authors describe a case of distal forearm skin necrosis caused by arginine extravasation that was treated by wide debridement and a combination of groin flap and later with split-thickness skin graft.
