Validity and Test-Retest Reliability of the TIVRE-Basket Test for the Determination of Aerobic Power in Elite Male Basketball Players

2016

The aims of this study were to (a) determine the relationship between performance on the court-based TIVRE-Basket test and peak aerobic power determined from a criterion laboratory-based incremental treadmill test and (b) to examine the test-retest reliability of the TIVRE-Basket test in elite male basketball players. To address aim 1, 36 elite male basketball players (age: 25.2 ± 4.7 years, weight: 94.1 ± 11.4 kg, height: 195.83 ± 9.6 cm) completed a graded treadmill exercise test and the TIVRE-Basket within 72 hours. The mean distance recorded during the TIVRE-Basket test was 4001.8 ± 176.4 m, and mean VO2 peak was 54.7 ± 2.8 ml · kg(-1) · min(-1), and the correlation between the 2 parame…

Multisectorial changes in the ciliary muscle during accommodation measured with high-resolution optical coherence tomography

2019

ABSTRACT Purpose: To measure changes in the anterior ciliary muscle during accommodation at the nasal, superior, temporal, and inferior sectors by means of an anterior chamber optical coherence tomographer, and correlate them with vergence changes. Methods: Twenty-four subjects with healthy, phakic eyes, whose mean age was 27.1 ± 8.9 years, underwent measurement with an anterior chamber optical coherence tomographer. The anterior ciliary muscle was measured at the nasal, temporal, superior, and inferior sectors for 0, -1, -2, and -3 D of vergence. A linear model was used to assess the correlation of each eye parameter with the accommodative demand. Results: The anterior ciliary muscle area …

The reliability of the SADS-LA in a family study setting

1991

The joint-rater and test-retest reliability study of two translated versions of the SADS-LA (Schedule for Affective Disorders and Schizophrenia--Lifetime version--modified for the study of anxiety disorders), one in French and the other in German, have been tested in family study settings, in a sample of patients and first-degree relatives. The test-retest reliability study demonstrated that identification of major affective disorders and schizophrenia was performed with sufficient reliability; however, diagnoses of subtypes of major disorders (e.g. bipolar II disorder) and identification of minor disorders was less reliable. The implications of these findings in phenotype identification du…

Clinical evaluation of nanocrystalline hydroxyapatite paste in the treatment of human periodontal bony defects--a randomized controlled clinical tria…

2008

The aim of this study was to compare the clinical outcome of intrabony periodontal defects following treatment with a novel nanocrystalline hydroxyapatite (NHA) paste to open flap debridement.Twenty-eight subjects, each displaying one intrabony defect with probing depth (PD)or =6 mm and radiographic evidence of an intraosseous componentor =3 mm participated in the present study. Subjects were allocated randomly to treatment with NHA paste (test group) or open flap debridement (control group). At baseline and at 6 months after surgery, the following clinical parameters were recorded by a masked examiner: plaque index, gingival index, PD, clinical attachment level (CAL), and gingival recessio…

Adult attachment and gene polymorphisms of the dopamine D4 receptor and serotonin transporter (5-HTT).

2010

Recently, the Dopamine D4 Receptor Gene (DRD4) and the Serotonin Transporter Gene (5-HTT) have been found to be candidate genes for infant attachment disorganization. The present study aimed to explore the relationship of these genes to adult attachment representations. The Adult Attachment Interview was used to assess attachment representations in 167 German adults. DNA from buccal cells was genotyped for the DRD4 VNTR Exon III and 5-HTT LPR polymorphisms with respect to the presence of the 7repeat allele and the short allele, respectively. DRD4 7repeat allele carriers were significantly more likely to be securely attached than those without 7repeat but only for subjects with unloving care…

Transarterial Chemoembolization in Patients Not Eligible for Liver Transplantation: Single-Center Results

2008

OBJECTIVE. The purpose of this study was to evaluate the effectiveness of transarterial chemoembolization in the care of patients not eligible for liver transplantation.CONCLUSIONS. Prognosis depends on local response, Okuda score, α-fetoprotein level, and tumor size and is independent of the presence of portal venous thrombosis.

Circadian rhythm in the torque developed by elbow flexors during isometric contraction. Effect of sampling schedules.

1997

Time-dependent changes in elbow flexion torque have been documented according to two different sampling schedules. Seven physical education students took part in the first series of experiments, and 7 other similar subjects in the second. In both sets of experiments, the subjects performed isometric contractions: maximal and submaximal at 90 degrees in the first experiments and maximal at different angular positions in the second. After a 30-minute rest period, the torque developed was measured at 00:00, 06:00, 09:00, 12:00, 15:00, 18:00, and 21:00 h on the day of the experiment. These subjects remained in the laboratory for 24 h. In the second series of experiments, the torque developed wa…

VBM-DTI correlates of verbal intelligence: a potential link to Broca's area.

2012

Abstract Human brain lesion studies first investigated the biological roots of cognitive functions including language in the late 1800s. Neuroimaging studies have reported correlation findings with general intelligence predominantly in fronto-parietal cortical areas. However, there is still little evidence about the relationship between verbal intelligence and structural properties of the brain. We predicted that verbal performance is related to language regions of Broca's and Wernicke's areas. Verbal intelligence quotient (vIQ) was assessed in 30 healthy young subjects. T1-weighted MRI and diffusion tensor imaging data sets were acquired. Voxel-wise regression analyses were used to correla…

Candidal carriage in the oral cavity of human immunodeficiency virus–infected subjects

2002

Abstract Objectives. We sought to assess asymptomatic oral carriage of Candida species and relative density in human immunodeficiency virus-infected (HIV+) subjects, as well as to determine whether yeast carriage is associated with CD4+cell count, HIV-1 RNA quantity, gender, route of HIV transmission, antiretroviral therapy, or smoking. Study Design. A cross-sectional analysis of oral rinses from HIV+ and healthy subjects was undertaken. Oral candidal carriage and relative species were investigated in 42 HIV+ and 41 healthy individuals, all of whom were seen at the Palermo University Department of Oral Sciences, Italy. Data were managed and analyzed by means of the computer software package…

Permanent Stoma After Low Anterior Resection for Rectal Cancer

2010

BACKGROUND AND OBJECTIVES: A low anterior resection procedure for removing a rectal tumor aims to preserve the sphincter and avoid a permanent stoma. Permanent stomas are primarily necessary in cases of poor anorectal function and local recurrence. The aim of this study was to clarify whether anastomosis-related complications and local recurrence influenced the rate of permanent stomas in a long-term follow-up. METHODS: Of 1032 consecutive patients with rectal cancer, 397 were treated by low anterior resection (R0 and R1 resections) between 1985 and 2007 at the Department of General and Abdominal Surgery of the University Hospital, Mainz (Germany). All patient data were collected prospectiv…
