The QT variability index (QTVI), which measures the instability of myocardial repolarization, is usually calculated from a single electrocardiogram (ECG) recording and can be easily applied in children. It is well known that frequency analysis of heart rate variability (HRV) can detect autonomic balance, but it is not clear whether QTVI is correlated with autonomic tone. Therefore, we evaluated the association between QTVI and HRV to elucidate whether QTVI is correlated with autonomic nervedoi:10.1007/s00246-020-02399-8 pmid:32572546 fatcat:5fl4b6lfp5exnjfy43be44byry

The RR and QT intervals of 60 continuous heart beats were measured, and the QTVI was calculated using the formula of Berger et al. Frequency analysis of HRV, including the QTVI analysis region, was conducted for 2 min and the ratio of low-frequency (LF) components to high-frequency (HF) components (LF/HF) and HF/(LF + HF) ratio was calculated as indicators of autonomic nerve activity. Then, the correlations between QTVI and these parameters were assessed. QTVI showed a significant positive correlation with LF/HF ratio (r = 0.45, p < 0.001) and negative correlation with HF/(LF + HF) ratio (r = -0.429, p < 0.001). These correlations remained after adjustment for sex and age. QTVI, which is calculated from non-invasive ECG and can detect abnormal myocardial repolarization, is significantly correlated with frequency analysis of HRV parameters. QTVI reflects autonomic nerve balance in children.
Objectives To evaluate the clinical utility of transrectal power Doppler imaging (PDI) of the prostate for detecting prostate cancer in patients with abnormally high serum levels of prostate speci®c antigen (PSA). Patients and methods Patients (107) with abnormally high serum PSA levels were assessed using a digital rectal examination (DRE), transrectal ultrasonography (TRUS) and PDI. Any hypervascular lesion on PDI was graded on a scale of 0±3, where grade 1±3 was considered positive and gradedoi:10.1046/j.1464-410x.2000.00663.x pmid:10848693 fatcat:lpilrlc425c7tgjz4af4lddwwa

Results Needle biopsy con®rmed prostate cancer in 41 (24%) of the 170 patients. PDI was positive in 68, of whom 40 (59%) had prostate cancer; all those but one having prostate cancer were positive on PDI. Thus, PDI had a high sensitivity of 98% (40/41) and a negative predictive value of 99% (101/102). PDI could have saved a signi®cant number of patients from undergoing unnecessary biopsies, compared with DRE and TRUS (P < 0.001). Conclusion The use of PDI in detecting prostate cancer might reduce the number of unnecessary needle biopsies of the prostate in patients with abnormally high serum PSA levels.

━━ Background. A pulmonary tumorlet is a rare tumor-like lesion, recognized as hyperplasia of neuroendocrine cells. Most tumorlets are incidentally found in resected lung specimens with chronic respiratory diseases. The association of pulmonary tumorlets with primary lung carcinoma is extremely rare. Cases. Case 1: Computed tomography (CT) showed a 50-mm tumor in the right lower lobe and swelling of the ipsilateral hilar lymph node. The tumor was diagnosed as non-small cell carcinoma by adoi:10.2482/haigan.61.959 fatcat:2fjcvh6vejcvzdjzbsbxa4v7y4

A tumorlet was found near the carcinoma tissue. Case 2: CT showed a 40×30-mm mass in S 5 of the right middle lobe with a 3-mm nodular shadow. The right middle lobe was resected, and a histopathological examination revealed adenocarcinoma and a tumorlet 3×1.5 mm in size near the carcinoma tissue. Conclusion. Although it is important to differentiate lung tumorlets from malignant tumors, the number of reports is small because of their rarity. We experienced two cases of pulmonary tumorlets complicated by primary lung cancer.
A water-soluble polymer having galactose pendant groups was prepared by the synthesis and radical polymerization of p-vinylbenzyl galactoside. Copolymerization of the galactoside with p-vinylphenyl acetate and subsequent [ 125 l]labeling by a chloramine-T method afforded a radio-labeled galactose-containing polymer, and the body distribution of the polymer in mice was examined along with that of galactosylated bovine serum albumin (BSA).

The excretion of the synthetic vinyl polymer from the liver was very slow, and 92% and 63% of the administered radioactivity still remained in the liver 2 and 24 h after the injection, respectively, while only 18% of the radioactivity was recovered 2h after the injection of [ 14 C]labeled galactosylated BSA.

To realize context aware applications for smart home environments, it is necessary to recognize function or usage of objects as well as categories of them. On conventional research for environment recognition in an indoor environment, most of previous methods are based on shape models. In this paper, we propose a method for recognizing objects focused on the relationship between human actions and functions of objects. Such relationship becomes obvious on human action patterns when he or shedoi:10.1109/fgcn.2008.62 dblp:conf/fgcn/MikiKK08 fatcat:rc2mxah46ndtjmztteh3qjzncu

By learning human actions toward objects statistically, objects can be recognized. Finally, we performed experiments and confirmed that objects can be recognized from human actions without shape models.

Guidelines require commissioning for deformable image registration (DIR) software before clinical use. The accuracy of DIR software depends upon data used. If common datasets for the DIR commissioning are available, the DIR results using the common datasets would be useful as an accuracy benchmark. Thus, the DIR-database (DIR-DB) was developed for DIR accuracy check and was open to access, which included radiotherapy plan data. This study was approved by Institutional Review Board (IRB).

Cone-beam computed tomography (CBCT) images for patient setup were also collected and recorded in the DIR-DB, if it is available. All recorded data were anonymized and were allowed to access by users in Japan with the IRB approval. The accuracy metrics of DIR; Hausdorff distance, mean distance to agreement, Dice similarity coefficient, Jaccard were put up on the DIR-DB web site. The number of recorded cases were 11 cases for head and neck, 16 cases for thorax, 7 cases for abdomen, 8 cases for pelvis and 6 cases for prostate treated with brachytherapy. The number of case for CBCT was 17 cases. It was meaningful for DIR accuracy check in Japan that the DIR-DB and DIR results using the data in the database were released.
The LHD experiment has gone through 5 campaign periods over the past 4 years, during which the diagnostics data continues to grow and the primary 28 measurements produce about 620 MB/shot in 150 shot/day 3-minute cycles. In 2002, 30-minute long-pulse experiments will be carried out in LHD, where real-time operations are indispensable for plasma measurements and data acquisition. The new scheme for utilizing conventional CAMAC digitizers in long-pulse experiments has been discussed and examined.doi:10.1016/s0920-3796(03)00329-6 fatcat:jgnx2phwifbdderl6ig33aajne

The new CompactPCI-based digitizer frontend has performed about 84 MB/s continuous acquisition in benchmarks, and has been formulated with the conventional CA-MAC system to make concurrent acquisitions.
The solid-phase analytical derivatization of phenols with pentafluoropyridine is performed. Fourteen phenols including chlorophenols and alkylphenols, could be efficiently adsorbed on a strong anion-exchange solid phase, Oasis MAX. The phenols adsorbed on Oasis MAX as phenolate ions were desorbed after derivatization with pentafluoropyridine. After optimization of the adsorption and derivatization, we established a procedure for the determination of the phenols in water samples by means ofdoi:10.1016/j.chroma.2004.05.012 pmid:15296382 fatcat:dlgsxmg7ibbjdoegkjkns37dnm

By processing 100 ml samples, the method detection limits (MDLs) were in the range of 0.45-2.3 ng/l for the alkylphenols (8.5 ng/l for nonylphenol) and 2.4-16 ng/l for the others. Compared with the biphasic reaction system, the signal-to-noise ratios obtained by the solid-phase analytical derivatization were significantly higher. This is ascribed to the fact that coexisting neutral and acidic compounds are efficiently removed from the sample solution by this solid-phase analytical derivatization system.
