The growth of mass communication system results the need for high gain compactable multi-antenna base station by employing recently introduced Multi-Input Multi-Output (MIMO) concept. A dual-band silicon patch antenna MIMO operating at 2.4GHz and 5GHz has been designed stimulated are presented in this paper. with dielectric constant 2.2 material RT-duroid efficiency low substrate loss. ADS soft...

In recent years, remarkable advances in sensitive analytical techniques have enabled the analysis of drugs in unconventional samples, such as sweat. In a study conducted during a methadone maintenance program, PharmChek sweat patches were applied to 20 subjects. The subjects were orally administered methadone in 1 dosage/day, and doses ranged from 80 to 100 mg. The sweat patch was applied 10 mi...

A new frontier in the administration of therapeutic drugs to veterinary species is transdermal drug delivery. The primary challenge in developing these systems is rooted in the wide differences in skin structure and function seen in species ranging from cats to cows. The efficacy of a transdermal system is primarily dependent upon the barrier properties of the targeted species skin, as well as ...

Mucoadhesive buccal patch releasing drug in the oral cavity at a predetermined rate may present distinct advantages over traditional dosage forms, such as tablets, gels and solutions. A buccal patch for systemic administration of acyclovir in the oral cavity was developed using polymers hydroxy propyl methyl cellulose (K4M), hydroxy propyl methyl cellulose (K15M), sodium carboxy methyl cellulos...

BACKGROUND In-stent restenosis (ISR) is the major limitation of percutaneous coronary stenting procedure. The elements like nickel, chromate and molybdenum are known to cause contact allergy. Hypersensitivity reaction, against these metal ions, may be one of the reasons of ISR. Cobalt chromium coronary stents, which are increasingly being used in percutaneous coronary interventions, have more n...

We examined the use of social information in fruitfly larvae, which represent an ideal model system owing to their robust learning abilities, small number of neurons and well-studied neurogenetics. Focal larvae showed attraction to the distinct odour emanating from food occupied by other larvae. In controlled learning experiments, focal larvae preferred novel odours previously paired with food ...

Acute left atrial thrombosis at the site of the resection of the primary cribriform septum is an exceedingly rare and important complication after atrial septal defect (ASD) closure with a pericardial or synthetic patch. This case report presents a mobile thrombus noted on the left atrium at the raw surface site of a resected cribriform primary septum that was not caught in the suture line with...
