1. Introduction The invention of radio, one of the most important inventions of the 20 th century is attributed to Guglielmo Marconi of Italy. Though it is disputed whether Nikola Tesla's patent on radio precedes that of Marconi, it is well-known that the first demonstration of radio transmission over several thousand miles was done by Marconi in the year 1901. There have been other claims of r...

Iminophosphoranes are coupled with CO2 and carbon-, nitrogen-, oxygen-, sulfur-based nucleophiles to synthesize acyclic (radio)pharmaceuticals in high yield.

G-protein-coupled brain receptors provide abundant targets for psychotropic drugs and have been widely explored by PET (positron-emission tomography) brain imaging. PET is a nuclear medicine technique consisting in injecting molecules that have been radiolabeled with positron-emitters such as fluoride-18 or carbon-11. When such radiotracers can be implemented in animal models or humans, they ar...

a chemiluminescence (cl) method has been developed for the determination of hydroxyzine (hyd) and its metabolite cetirizine (cet). the method is based on sensitizing effect of cet and hyd on the weak cl reaction between ru(phen)32+ and acidic ce(iv). a mechanism for the cl reaction has been proposed on the basis of uv-vis, fluorescent and cl spectra. by using the recommended procedure, the cali...

Radiotherapy and radiology have been indispensable components in cancer care for many years. The detection limit of small tumor foci as well as the development of radio-resistance and severe side effects towards normal tissues led to the development of strategies to improve radio-diagnostic and -therapeutic approaches by pharmaceuticals. The term "radiopharmaceutical" has been used for drugs la...

Animal imaging is getting tremendous importance in biomedical research areas including drug delivery, radiobiology and cancer research. Even though, imaging techniques like CT, PET, SPECT, MRI are available for experimental animals, luminescence-based molecular imaging is still considered as crucial and common tool for biomedical laboratories due to easy handling/maintenance, cost effectiveness...

The design of a low-cost beacon receiver based on software defined radio is presented. The motivation for such a receiver is to investigate atmospheric impairments at the Ka frequency band. The receiver has been tested by the Hotbird 13A, ASTRA 3B and Alphasat satellite beacon signals. A GNU Radio software development toolkit and a USRP device were used for the development of a beacon receiver ...

widespread use of pharmaceuticals has resulted in mixture concentrations ranging from mg/l in effluent to µg/l concentrations in surface water. in a 2008 study, 13 pharmaceuticals, ranging in amounts from 0.0028 to 0.1757 µg/l, were identified in the tennessee river, usa and its tributaries. in order to address the need for risk assessment of environmentally relevant pharmaceutical mixtures, da...
