‎A gyrogroup is a nonassociative group-like structure modelled on the ‎space of relativistically admissible velocities with a binary ‎operation given by Einstein's velocity addition law‎. ‎In this ‎article‎, ‎we present a few of groups sitting inside a gyrogroup G‎, ‎including the commutator subgyrogroup‎, ‎the left nucleus‎, ‎and the ‎radical of G‎. ‎The normal closure of the commutator subgyr...

titanium dioxide (tio2) nanoparticles, with an average size of about 45 nm, were encapsulated by polystyrene using in situ nitroxide mediated radical polymerization   in the presence of 3-aminopropyl triethoxy silane (aptes) as a coupling agent and 2, 2, 6, 6-tetramethylpiperidinyl-1-oxy  as a initiator. first, the initiator for nmrp was covalently bonded onto the surface of titanium dioxide na...

PURPOSE In this retrospective study, we aimed to compare the clinical characteristics of inguinal hernia developed after radical retropubic surgery for prostate cancer to the hernia without previous radical prostatectomy. METHODS Twenty-three patients (group A) who had radical retropubic surgery for prostate cancer underwent laparoscopic or open tension-free inguinal hernia repair from March ...

Different studies have demonstrated that the bioactivity of hydroxyflavones is due to their antioxidant and free radical scavenging activity. Recently, most interest has been devoted to structure-activity relationships; however, the main problems encountered in these studies are the low solubility of some hydroxyflavones in aqueous solution and the pro-oxidant character of the hydroxyl group at...

Purpose. Intravesical Bacillus Calmette-Guerin (BCG) immunotherapy is indicated for high-grade nonmuscle-invasive bladder cancer (NMIBC). The efficacy of BCG in patients with a history of previous pelvic radiotherapy (RT) may be diminished. We evaluated the outcomes of radical cystectomy for BCG-treated recurrent bladder cancer in patients with a history of RT for prostate cancer (PC). Methods....

Treatment of triphenylphosphine (Ph(3)P) with an excess of diisopropyl azodicarboxylate at 0-25 °C resulted in the formation of a symmetrical tetraalkyl tetrazetidinetetracarboxylate radical cation, containing the elusive cyclic N(4) ring system. Electron paramagnetic resonance (EPR) spectroscopy revealed a 9-line spectrum, with hyperfine coupling constants indicative of four almost magneticall...

The Pax gene family consists of tissue-specific transcriptional regulators that always contain a highly conserved DNA-binding domain with six cx-helices (paired domain), and, in many cases, a complete or residual homeodomain. Numerous genes of this family have been identified in animals, with the largest number found in vertebrates. Our evolutionary analyses indicate that the vertebrate Pax gen...
