Excitation functions of the Kr(d, α)Br, Kr(d, n)Rb and Kr(d, x)Kr reactions were measured for the first time in the energy range up to 13 MeV using the stacked gas cell technique and activation method. Highly enriched Kr was used as target material. The maximum cross section of the Kr(d, α)Br reaction at 13 MeV amounts to 21 mb and the calculated yield of Br over the energy range Ed = 13 → 4 Me...

using the gaussian 2003 software and mp2/ 6–311 ++ g** method for he: he, ne:ne andmp2/6-31g method for ar: ar, kr: kr and hf/sto-3g method for xe: xe, the optimizedinteraction energies between two like atoms of rare gases (he, ne, ar, kr and xe) as a functionof the distances between the centers of two considered atoms were evaluated and the resultswere interpreted according to the lennard – jo...

Transcriptional regulation by p53 is thought to play a role in its ability to suppress tumorigenesis. However, there remain gaps in understanding about how p53 regulates transcription and how disrupting this function may promote cancer. Here we report a role in these processes for the kidney cancer–related gene KR-POK (ZBTB7C), a POZ domain and Kr€ uppel-like zinc finger transcription factor th...

Prostaglandin 9-ketoreductase (PG-9-KR) was purified from pig kidney to homogeneity, as judged by SDS/PAGE using an improved procedure. The enzyme is pro-S stereoselective with regard to hydrogen transfer from NADPH with prostaglandin E2 as substrate and reduces its 9-keto group with approximately 90% stereoselectivity to form prostaglandin F2 alpha. Approximately 8% of the prostaglandin F form...

Hyperpolarized (hp) (83)Kr is a promising MRI contrast agent for the diagnosis of pulmonary diseases affecting the surface of the respiratory zone. However, the distinct physical properties of (83)Kr that enable unique MRI contrast also complicate the production of hp (83)Kr. This work presents a previously unexplored approach in the generation of hp (83)Kr that can likewise be used for the pro...

The (83)Kr magnetic resonance (MR) relaxation time T(1) of krypton gas in contact with model surfaces was previously found to be highly sensitive to surface composition, surface-to-volume ratio, and surface temperature. The work presented here explored aspects of pulmonary (83)Kr T(1) relaxation measurements in excised lungs from healthy rats using hyperpolarized (hp) (83)Kr with approximately ...

The role of acquired error-detection capabilities in skill learning was investigated by manipulating the delay of knowledge of results (KR). Compared with delayed feedback, instantaneous KR should be detrimental to the learning of error-detection capabilities because it should tend to block spontaneous subjective evaluation of response-produced feedback. Weaker error-detection capabilities shou...

Stem-toxic small molecules have been developed to induce selective cell death of pluripotent stem cells (PSCs) to lower the risk of teratoma formation. However, despite their high efficacies, chemical-based approaches may carry unexpected toxicities on specific differentiated cell types. Herein, we took advantage of KillerRed (KR) as a suicide gene, to selectively induce phototoxicity using vis...

OBJECTIVE We developed a Revised Korean version of the Geriatric Depression Scale (GDS-KR) and examined its reliability, validity, and factor structures. We also estimated its optimal cutoff scores for major depressive disorder (MDD) and minor depressive disorder (MnDD) stratified by age and education. METHODS The GDS-KR was administered to 888 subjects (61 MDD patients, 45 MnDD patients, and...

Feedback has been considered a fundamental component of the motor learning process (MAGILL, 2007; SCHMIDT & LEE, 2011; SCHMIDT & WRISBERG, 2008). During and after the execution of a movement, the learner normally receives two types of feedback about the performance, intrinsic and augmented. Intrinsic feedback is information that comes from the sensory system and augmented feedback comes from an...
