BACKGROUND We aimed to compare the sensitive and quality-controlled KRAS testing with direct sequencing and to assess the impact on decision making of treatment. PATIENTS AND METHODS We analysed genomic DNA isolated from macrodissected formalin-fixed paraffin-embedded specimens by direct sequencing and an amplification refractory mutation system-Scorpion(More)
BACKGROUND KRAS mutations are predictive markers for the efficacy of anti-EGFR antibody therapies in patients with metastatic colorectal cancer. Although the mutational status of KRAS is reportedly highly concordant between primary and metastatic lesions, it is not yet clear whether genotoxic chemotherapies might induce additional mutations. METHODS A(More)
The behavioral effects of L-dopa or cabergoline alone were compared with those of the joint administration of the two drugs in 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-lesioned parkinsonian cynomolgus monkeys with attention to the induction of hyperactivity and dyskinesia. Cabergoline alone at 0.2 mg/kg or less improved in a dose-dependent(More)
Sclerosing stromal tumor (SST) is an extremely rare benign tumor of the ovary that is derived from the sex cord stroma [1,2] and occurs in young women [3-11]. Preoperative diagnosis of the tumor is difficult as it often mimics a malignant tumor. Oophorectomy is usually performed in many cases of young women [3], and diagnosis of SST is made based on(More)
We studied the characterization of cabergoline, a new ergot alkaloid derivative and a selective dopamine D2 receptor agonist, in comparison to bromocriptine and pergolide in reserpine-treated rodents. Cabergoline (0.25-1.0 mg/kg, s.c.) improved dose-dependently the reserpine-induced akinesia that was assessed on the locomotor activity, and the efficacy(More)
