knowledge of results (KR) consists of presenting KR for each of a set of trials only after the last trial in the set has been completed. In experiment 1, motivated by a guidance hypothesis for KR, we searched for an optimal number of trials to be contained in the summary KR. Using a coincident-timing task with summary lengths of 1, 5, 10, and 15 trials, in a delayed no-KR retention test of lear...

Angiogenesis is important in the development and progression of cancer, therefore the therapeutic approach based on anti-angiogenesis may represent a promising therapeutic option. KR-31831 is a novel anti-ischemic agent. Previously, we reported the anti-angiogenic activity of KR-31831. In the present study we investigated the molecular mechanisms underlying anti-angiogenic activity of KR-31831....

It is a poem originally written in Urdu by the Pakistani Poet Akhtar Raza Saleemi. The speaks of scene that set desolate valley, surrounded mountains, where three men are conversing with each other, but someone listening, and awareness it causing them to freeze form statue. an allegorical poetic tale about censorship panopticon.

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...

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...

The relaxation of electronically excited atomic manganese isolated in solid rare gas matrices is observed from recorded emission spectra, to be strongly site specific. z 6P state excitation of Mn atoms isolated in the red absorption site in Ar and Kr produces narrow a 4D and a 6D state emissions while blue-site excitation produces z 6P state fluorescence and broadened a 4D and a 6D emissions. M...

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...
