Here, we present a hot injection synthesis of colloidal Ag chalcogenide nanocrystals (Ag(2)Se, Ag(2)Te, and Ag(2)S) that resulted in exceptionally small nanocrystal sizes in the range between 2 and 4 nm. Ag chalcogenide nanocrystals exhibit band gap energies within the near-infrared spectral region, making these materials promising as environmentally benign alternatives to established infrared ...

Pharmacotherapy is a major treatment method in healthcare centers, and the injection of powdered drugs is among common pharmacotherapy techniques. Medication errors and nosocomial infections are among major health issues in the world. On the other hand, powdered drugs are widely used in hospitals; however, drug mixture is a very time-consuming process. The objective of this invention was to acc...

The ability to detect low-abundance proteins in human body fluids plays a critical role proteomic research achieve comprehensive understanding of protein functions and early-stage disease diagnosis reduce mortality rates. Ultrasensitive (sub-fM), rapid, simple “mix-and-read” plasmonic colorimetric biosensing large-size (≈180 kDa) biofluids using an ultralow-noise multilayer molybdenum disulfide...

totally implantable venous access devices (tivad) or implantable catheter ports are devices which can be implanted subcutaneously. they enable prolonged and repeated access to the vascular system, into the peritoneal cavity or intravertebral space. this device is particularly useful for repeated medical injection, for blood sampling or transfusion of blood and blood derivatives and for total pa...

device-associated nosocomial infection is a significant part of nosocomial infection and can cause the majority of its mortality, morbidity, extra lengths of hospital stay and cost. in a 13-year review, the online database was searched for full articles to find research on epidemiology of device-associated nosocomial infection in pediatric and neonatal wards. twenty two papers were included fiv...

statement of problem: snoring is the most common sleep disorder which in itself may only be viewed as an obnoxious disturbance in human society; however it must be considered a potential indicator of significant medical problems such as: hypertension, obstructive sleep apnea, cerebrovascular infarction and ischemic heart disease. purpose: the purpose of this study was to evaluate the effectiven...

introduction:  stereotactic  radiosurgery  is  a  technique  for  the  treatment  of  intracranial  lesions  with  highly  collimated  x-ray  beam.  linac-based  radiosurgery  is  currently  performed  by  two  techniques:  couch or pedestal mounted. in the first technique, a device is required to affix patient's head to a couch  and  moreover  to  translate  it  accurately.  structure  of...
