Selective Endocytic Uptake of Targeted Liposomes Occurs within a Narrow Range of Liposome Diameters.

Cell surface receptors facilitate signaling and nutrient uptake. These processes are dynamic, requiring receptors to be actively recycled by endocytosis. Due to their differential expression in disease states, receptors are often the target of drug-carrier particles, which are adorned with ligands that bind specifically to receptors.

Steric pressure between glycosylated transmembrane proteins inhibits internalization by endocytosis.

Clathrin-mediated endocytosis is essential for the removal of transmembrane proteins from the plasma membrane in all eukaryotic cells. Many transmembrane proteins are glycosylated. These proteins collectively comprise the glycocalyx, a sugar-rich layer at the cell surface, which is responsible for intercellular adhesion and recognition.

Investigation of an XDR- ST2 outbreak in an intensive care unit of a Lebanese tertiary care hospital.

We sought to investigate the genetic epidemiological relatedness of carbapenem-resistant (CRAB) strains of a suspected outbreak in a Lebanese tertiary care hospital to implement necessary infection prevention and control measures. Twenty-eight nonduplicate CRAB isolates detected among hospitalized patients between January 2016 and July 2017 were studied by real-time polymerase chain reaction (PCR), pulsed-field gel electrophoresis and multilocus sequence typing analyses. Twenty-seven isolates harbored , of which one also carried .

Molecular mechanisms of antimicrobial resistance in Acinetobacter baumannii, with a special focus on its epidemiology in Lebanon.

Acinetobacter baumannii is an opportunistic bacterium involved in several types of infection with high mortality and morbidity, especially in intensive care units. Treatment of these infections remains a challenge due to the worldwide emergence of broad-spectrum resistance to many antibiotics. Following the implementation of molecular techniques to study A.
