DRUG MISUSE AND SELF-MEDICATION AMONG PHARMACY STUDENTS IN JORDAN.

Objective: Aim: To estimate risks and prevalence of self-medication and potential abuse risk among pharmacy students in Jordanian Universities.

Patients And Methods: Materials and Methods: A cross-sectional study design was conducted with 450 students, selected using multistage sampling methods, from seven different universities. Data was collected by self-administrated questionnaires covering demographic and academic information, health-related information, use of self-medication, and pattern of self-medication among pharmacy students.

Extracellular vesicles are conduits for E. coli heat-labile enterotoxin (LT) and the B-subunits of LT and cholera toxin in immune cell-to-cell communication.

Several pathogens excrete their toxins either directly into the host or through extracellular vesicles. Enterotoxigenic E. coli is capable of secreting heat-labile toxin LT in extracellular vesicles (EVs) which are delivered to mammalian cells.

Uniqueness of RNA Coliphage Qβ Display System in Directed Evolutionary Biotechnology.

Phage display technology involves the surface genetic engineering of phages to expose desirable proteins or peptides whose gene sequences are packaged within phage genomes, thereby rendering direct linkage between genotype with phenotype feasible. This has resulted in phage display systems becoming invaluable components of directed evolutionary biotechnology. The M13 is a DNA phage display system which dominates this technology and usually involves selected proteins or peptides being displayed through surface engineering of its minor coat proteins.
