Swimming bacteria display a remarkable tendency to move along flat surfaces for prolonged times. This behavior may have a biological importance but can also be exploited by using microfabricated structures to manipulate bacteria. The main physical mechanism behind the surface entrapment of swimming bacteria is, however, still an open question. By studying the swimming motion of Escherichia coli...

Stent entrapment is a very rare complication of percutaneous coronary intervention. The interventional approach could be a treatment strategy. However, if it does not work, surgical treatment should be considered. Here, we report a case of surgical treatment of stent entrapment in the left coronary sinus of a 53-year-old male patient.

In this study, nystatin liposomal formulation was prepared and characterized. The physicochemical properties of formulations including vesicle size, drug entrapment stability and in vitro release were studied. The highest entrapment efficiency of nystatin into liposomes was obtained about 70% when cholesterol (CHO) was added to the formulations prepared with dipalmitoylphosphatidylcholine. In a...

BACKGROUND Low drug entrapment efficiency of hydrophilic drugs into poly(lactic-co-glycolic acid) (PLGA) nanoparticles is a major drawback. The objective of this work was to investigate different methods of producing PLGA nanoparticles containing minocycline, a drug suitable for periodontal infections. METHODS Different methods, such as single and double solvent evaporation emulsion, ion pair...

Cubital tunnel syndrome is the most common form of ulnar nerve entrapment and the second most common entrapment neuropathy of the upper extremity after carpal tunnel syndrome. However, bilateral compressive ulnar neuropathy is a rare condition. Electro diagnostic studies are a valid and reliable means of confirming the diagnosis.

The hypothesis that the chronic tennis-elbow syndrome is caused by an entrapment neuropathy of the radial nerve (Roles and Maudsley 1972) was put to the test prospectively in ten patients. Detailed orthopaedic, neurological and neurophysiological examinations did not reveal any involvement of the radial nerve. It is concluded that this syndrome cannot be explained by an entrapment neuropathy.

Popliteal artery entrapment syndrome is a rare cause of peripheral vascular disease, often affecting young adults. Multiple studies have shown that osteochondromas can cause vascular injury. Intermittent compression, pseudoaneurysm, thrombosis, distal embolism, and venous thrombosis have all been described as possible complications. Here we present a case of popliteal arterial entrapment type I...

La rétinopathie d'irradiation est une pathologie vasculaire rétinienne iatrogène, chronique et progressive, secondaire à une radiothérapie de tumeurs intraoculaires ou de tumeurs malignes avoisinantes. Il s'agit d'une microangiopathie rétinienne occlusive retardée et progressive qui regroupe la rétinopathie (ischémique ou proliférante) et la maculopathie (ischémique ou œdémateuse). Une neuropat...
