as drug delivery systems nanoparticulan widely investigated because of many advantages such as smaller size,controlled drug release potential targeting ability, enhancement of therapeutic efficacy and reduction oftoxicity. so, carbon nanotubes have recently received considerable attention as alternative drug delivery carrierin this study we investigate interaction of tamoxifen with open-end of ...

OBJECTIVE The purpose of this study was to develop a novel scoring system to screen subjects who have a high risk for colorectal neoplasia. STUDY DESIGN AND SETTING We retrospectively analyzed 1061 subjects undergoing total colonoscopy (TCS) for the first time at Gihoku Kosei Hospital. The characteristics and habits of the subjects were analyzed using a multivariate logistic regression analys...

Submitted on: 06/20/2009 Approved on: 09/10/2009 We declare no confl ict of interest. aBStRaCt Introduction: Needle infiltration of local anesthetic is a painful procedure, thus, a topical anesthetic is a comfortable alternative. However, it is difficult to deliver transcutaneous polar drugs. Iontophoresis is a noninvasive technique that uses electrical current for releasing electrically charge...

Synopsis of Video Botulinum Toxin A (BTxA) is used widespread in neurology and plastic surgery with very good results. Some groups used BTxA for the treatment of detrusor hyperreflexia in spinal cord injury. We propose BTxA in children with incomplete spinal lesion and detrusor hyperreflexia refractory to anticholinergic medication, where bladder augmentation is the only alternative. We enrolle...

Whole-exome sequencing (WES) has been increasingly useful for the diagnosis of patients with rare causes of anemia, particularly when there is an atypical clinical presentation or targeted genotyping approaches are inconclusive. Here, we describe a 20-yr-old man with a lifelong moderate-to-severe anemia with accompanying splenomegaly who lacked a definitive diagnosis. After a thorough clinical ...

4(S)-Hydroxyproline (Hyp) residues constitute about 10% of most forms of collagen, the most abundant protein in vertebrates. X-Ray diffraction analysis was used to ascertain how the structure of proline residues is affected by the inductive effect elicited by the hydroxyl group of Hyp residues. N-Acetylproline methylester (1), N-acetyl-4(S)-hydroxyproline methylester (2) and N-acetyl-4(S)- fluo...

PURPOSE To determine if models of ovarian clear cell carcinomas (OCCCs) harbouring defects in homologous recombination (HR) DNA repair of double strand breaks (DSBs) are sensitive to cisplatin and/or PARP inhibition. EXPERIMENTAL DESIGN The HR status of 12 OCCC cell lines was determined using RAD51/γH2AX foci formation assays. Sensitivity to cisplatin and the PARP inhibitor BMN-673 was correl...

Two tetramethyl-substituted dispiro-1,2,4,5-tetraoxanes (7,8,15, 16-tetraoxadispiro[5.2.5.2]hexadecanes) 3 and 4 were designed as metabolically stable analogues of the dimethyl-substituted dispiro-1, 2,4,5-tetraoxane prototype WR 148999 (2). For a positive control we selected the sterically unhindered tetraoxane 5 (7,8,15, 16-tetraoxadispiro[5.2.5.2]hexadecane), devoid of any substituents. Tetr...
