A 10-year-old female patient presented with a rapidly growing nodular mass lesion on her right frontal area. On skull radiography and computed tomography (CT) imaging, this mass had a well-demarcated punch-out lesion with a transdiploic, exophytic soft tissue mass nodule on the frontal scalp. Magnetic resonance (MR) imaging revealed the presence of a(More)
Cyclin-dependent kinases (Cdks) have been attractive targets for the development of anticancer therapeutic agents. In an effort to generate a new class of anti-Cdk inhibitors, we synthesized aryl aminopyrimidines and examined the effect of these compounds in both in vitro kinase assays and cultured cells. Two of these compounds, BMI-1026 and BMI-1042,(More)
Let G be a graph on n vertices with r := n/2 and let λ1 ≥ · · · ≥ λn be adjacency eigenvalues of G. Then the Hückel energy of G, HE(G), is defined as HE(G) = (2 P r i=1 λi, if n = 2r; 2 P r i=1 λi + λr+1, if n = 2r + 1. The concept of Hückel energy was introduced by Coulson as it gives a good approximation for the π-electron energy of molecular graphs. We(More)
BACKGROUND It is widely accepted that cervical interlaminar steroid injection (CIESI) is more effective in treating radicular pain than axial neck pain, but without direct comparison. And the differences of effect after CIESI according to MRI findings are inconsistent. In this retrospective study, we evaluated the therapeutic response of CIESI according to(More)
Psychrobacter alimentarius PAMC 27889, a Gram-negative, psychrophilic bacterium, was isolated from an Antarctic rock sample. Here, we report the complete genome of P. alimentarius PAMC 27889, which has the nonmevalonate methylerythritol phosphate pathway of terpenoid biosynthesis and a complete gene cluster for benzoate degradation.
OBJECTIVE High-molecular-weight hydroxyethyl starch (HES) compromises blood coagulation more than does low-molecular-weight HES. We compared the effects of low- and high-molecular-weight HES for the treatment of vasospasm and investigated the dose relationship with each other. METHODS Retrospectively, in a series of consecutive 102 patients with(More)
Because the activation of matrix metalloproteinases (MMP) is a key factor in the metastatic process, compounds with the ability to inhibit MMP activity have a potential in the treatment of tumor. From the examination of 2000 plant extracts, obovatal isolated from the extract of the leaves of Magnolia obovata THUNB was a potent inhibitor of MMP-2 enzyme in(More)
The hydroxamic acid analogues (2) of the natural product gelastatins (1) were prepared by 1 step conversion reaction. The synthetic analogues (2) showed potent enzymatic inhibitory activities against MMP-2, MMP-9, and TACE IC50's of 6, 23, and 28 nM, respectively. In addition, 2 were able to inhibit TNF-alpha production effectively in mice as well as in a(More)
Cryobacterium arcticum PAMC 27867, a psychrotolerant, Gram-positive bacterium, was isolated from a sedimentary rock sample collected at Eureka Spurs in northern Victoria Land, Antarctica. Here, we report the genome sequence of C. arcticum PAMC 27867.
BACKGROUND The active involvement of anesthesiologists in chronic pain management has been associated with an increase in the number of related medical dispute cases. METHODS Using the Korean Society of Anesthesiologists Legislation Committee database covering case files from July 2009 to June 2016, we explored injuries and liability characteristics in a(More)
