blood and body fluid exposure is a major occupational safety problems for health care workers. therefore, we conducted a descriptive and retrospective study to identify the characteristics of blood exposure accidents in health care settings which lasted five years (2005-2009) at the two university hospitals of sfax. we have 593 blood exposure accidents in health care settings 152 (25.6%) health...

In normal serum, saline dialysis for 48 hours in Visking casing resulted in folate clearance closely comparable to that produced by haemoglobin-coated charcoal adsorption, except in kwashiorkor where charcoal removed a greater proportion of folate. Pre- and post-dialysis values probably represented total and bound folate, respectively. Urinary folate consisted almost exclusively of dialyzable o...

BACKGROUND Telomerase is a ribonucleoprotein that maintains chromosomal telomere length. Telomerase is not active in nonmalignant somatic cells, but is activated in most human cancers. Telomerase activity in easily obtainable body fluids that bathe tumors may be a useful cancer marker, especially when used in conjunction with conventional cytology. APPROACH Results from studies that assayed t...

Biopolymers such as carrageenan or collagen can be used carriers for loading a drug to enhance drug’s bioavailability. In this work, allopurinol was loaded on carrageenan/collagen blend and the carrageenan/collagen/allopurinol (CCA) biocomposite films were prepared using ionic gelation method combined with 3D printing gel ink material. The advantages of are ease in shaping design controlling th...

Bioceramics, because of its excellent biocompatible and mechanical properties, has always been considered as the most promising materials for hard tissue repair. It is well know that an appropriate cellular response to bioceramics surfaces is essential for tissue regeneration and integration. As the in vivo implants, the implanted bioceramics are immediately coated with proteins from blood and ...

background and objective: antibiotic resistance is increasing, especially in healthcare-associated infections causing significant public health concerns worldwide. national information is required to make appropriate policies, update list of essential drugs for treatment, and evaluate the effects of intervention strategies. a nationwide surveillance of antimicrobial resistant bacteria in nosoco...
