The computer program PAAS 3 is developed to determine the probable amino acid sequences of a peptide from sequence ion peaks experimentally obtained by mass spectrometry.
Abstract The intermolecular dehydrogenative coupling of 1,1,1,3,5,5,5-heptamethyltrisiloxane with aromatic compounds such as aryloxazolines and arylimines in the presence a catalytic amount [RuCl2(p-cymene)]2 gave corresponding ortho-silylated products good yields.
Electrospray ionization mass spectra of human hemoglobin chains and transferrin were acquired on a magnetic sector spectrometer. The observed molecular ion for each chain was in good agreement with the theoretical isotopic distribution at reasonable resolution 2000. clear separation variant beta-chain admixture normal counterpart 15,867 that differed from it by 14 Da (0.09%) ensured smaller difference could be detected. ions too broad compared shape to determine accurately, probably due...
This study aimed to validate and reanalyze urinary biomarkers for detecting colorectal cancers (CRCs). We previously conducted metabolomic analyses using capillary electrophoresis-mass spectrometry found a significant difference in various metabolites, especially polyamines, between patients with CRC healthy controls (HC). analyzed additional samples confirmed consistency the newly data. In total, we included 36 HC, 34 adenoma (AD), 214 samples, which were used subsequent analyses. Among 132...
Objective. This study evaluated the 5-year failure rate of naftopidil (NAF) or tamsulosin hydrochloride (TAM) in lower urinary tract symptoms associated with benign prostatic hyperplasia (BPH/LUTS) and compared prognostic factor two α1-blockers. Material methods. A total 131 patients International Prostate Symptom Score (IPSS) ≥ 8 IPSS quality life (IPSS-QOL) 3 BPH/LUTS receiving treatment α1-blockers had been administered NAF TAM, rates were calculated for 5 years. Age, prostate volume...
Abstract Background Cerebral blood flow (CBF) and dopamine transporter (DAT) images are clinically used for the differential diagnosis of parkinsonian disorders. Objectives This study aimed to examine correlation CBF with striatal DAT in patients Parkinson's disease (PD) atypical syndromes (APS) evaluate diagnostic power DAT‐correlated PD through machine learning each imaging modality alone or combination. Methods Fifty‐eight 71 APS (24 multiple system atrophy, 21 progressive supranuclear...
The ion optics of multi-turn time-of-flight (TOF) mass spectrometry was investigated. Two feasible systems using toroidal sector plus quadrupole lenses and cylindrical sectors doublets were found. combination a linear TOF with figure-of-eight type system is proposed. © 1997 John Wiley & Sons, Ltd.
Abstract Background Recently, robot-assisted minimally invasive esophagectomy (RAMIE) has gained popularity worldwide. Some studies have compared the long-term results of RAMIE and (MIE). However, there are no reports on outcomes in Japan. This study MIE. Methods retrospective included 86 patients with thoracic esophageal cancer who underwent or MIE at our hospital from June 2010 to December 2016. Propensity score matching (PSM) was employed, incorporating co-variables such as confounders...
