primary pleuropulmonary synovial sarcomas are rare soft tissue malignancies; combined metastatic involvement of the heart is extremely rare. in this case report, a 17-year-old female presented with a history of chest pain. chest radiographs revealed a round mass in the left upper hemithorax, and computed tomography (ct) showed a well-defined heterogeneous enhancing mass abutting the pleura. a c...

Abstract The QCD axion is a particle postulated to exist since the 1970s explain strong-CP problem in physics. It could also account for all of observed dark matter Universe. resonant interaction detection experiment (ARIADNE) intends detect by sensing fictitious ‘magnetic field’ created its coupling spin. Short-range axion-mediated interactions can occur between sample laser-polarized 3 He nuc...

PURPOSE The most recent Varian(®) micro multileaf collimator (MLC), the High Definition (HD120) MLC, was modeled using the BEAMNRC Monte Carlo code. This model was incorporated into a Varian medical linear accelerator, for a 6 MV beam, in static and dynamic mode. The model was validated by comparing simulated profiles with measurements. METHODS The Varian(®) Trilogy(®) (2300C/D) accelerator m...

A cemented, cast CoCr alloy, Omnifit Plus femoral stem was retrieved following mid-stem fracture after 24 years in vivo. The patient was an active 55-year-old male with a high body mass index (31.3) and no traumatic incidents before stem fracture. Fractographic and fatigue-based failure analyses were performed to illuminate the etiology of fracture and retrospectively predict the device lifetim...

The regulation of chromatin mobility in response to DNA damage is important for homologous recombination in yeast. Anchorage reduces rates of recombination, whereas increased chromatin mobility correlates with more efficient homology search. Here we tracked the mobility and localization of spontaneous S-phase lesions bound by Rad52, and find that these foci have reduced movement, unlike enzymat...

We have developed a cDNA library screening method which allows the simultaneous screening of >10 ( 12 ) double-stranded plasmid cDNA molecules with minimal a priori sequence knowledge. A biotinylated, gene-specific oligonucleotide probe along with abutting 'blocking' oligos is hybridized to the plasmid cDNA library and the target plasmid retrieved with paramagnetic streptavidin beads and transf...
