Fatigue and Recovery After High-Intensity Exercise Part I: Neuromuscular Fatigue
2004
The contribution of central and peripheral factors to muscle fatigue were quantified following a high-intensity uphill running exercise. Eight male volunteers performed an intermittent exercise at 120 % of maximal aerobic speed on a treadmill with an 18 % grade. Electrically evoked and voluntary contractions of the knee extensors and EMG of the two vastii were analyzed before and immediately after the high-intensity exercise. Isometric maximal voluntary contraction decreased slightly (-7+/-8 %; p < 0.05) after exercise but no changes were found in the level of maximal activation or in the torque produced by a 80 Hz maximal stimulation applied to the femoral nerve. Following exercise, the si…
Survival of immediately versus delayed loaded short implants: a prospective case series study
2015
Background: To assess and compare survival rates of immediately and delayed loaded short implants (7 mm) in free ends of a partially edentulous jaw with moderate-severe alveolar bone resorption. Material and Methods: 24 patients with atrophic edentulous free-ends were included in this prospective study. Four study groups were monitored monthly and their behavior was evaluated: bridges supported only by short implants and mixed short and long implant bridge groups, both with immediate and delayed loading. Failures, bone loss, probing depth and bleeding on probing were evaluated. Results: 54 Mk III Shorty TiU and 15 Brånemark System®MK III TiU implants with a length longer than 7mm were inclu…
Soft and hard tissue alterations around implants placed in an alveolar ridge with a sloped configuration.
2012
Aim: The aim of this study was to evaluate soft and hard tissue alterations around implants placed in healed, sloped ridge sites. Materials and methods: In this prospective multi-center study, 65 patients between 20 and 74 years of age and with a need for a single tooth replacement were included. All patients presented with a recipient implant site demonstrating a lingual‐buccal bone height discrepancy of 2.0‐5.0 mm and with a neighboring tooth on its mesial aspect. Implant placement (OsseoSpeed Profile implants; Astra Tech AB, M! olndal, Sweden) was performed using a non-submerged installation procedure. The implants were placed in such a way that the sloped part of the device was located …
A new morphologic classification of the alveolar ridge after distraction osteogenesis in human patients. A 17 years retrospective case series study
2020
Background To perform a morphologic classification based on the results of bone augmentation after a distraction osteogenesis. Material and Methods Thirty-four (34) patients (24 women and 10 men; mean age, 47.1 years (SD=9.5); age range, 23 to 62 years) underwent a total of 42 alveolar ridge distractions before the placement of a total of 89 dental implants. Ridge bone morphology was evaluated as the main ordinal variable. Chi-squared, Kruskal-Wallis and ANOVA one-way test were used. Results Category I (30.95%): consisted of wide alveolar rim and no bone defects Category II (28.57%): wide alveolar rim, lateral bone surface concavity. Category III (23.81%): narrow alveolar rim, lateral bone …
Relationships between satisfaction with life, posttraumatic growth, coping strategies, and resilience in cancer survivors: A network analysis approach
2021
Objective Cancer survivors' satisfaction with life should be seen through the psychological factors related to a person's capabilities to face and handle the situation. This study aimed to (1) examine the relationships of satisfaction with life, posttraumatic growth, resilience and coping strategies in a global network model, (2) find the bridge indicators between satisfaction with life and the other constructs, and (3) test for the invariance of the network structures across several moderating variables. Methods In a heterogeneous sample of 696 cancer survivors (69% female; mean age = 53.1 ± 15.44 years; median time from being diagnosed = 4 years; breast cancer was the most frequent type o…
Validity of the Colposcopic Criteria Inner Border Sign, Ridge Sign, and Rag Sign for Detection of High-Grade Cervical Intraepithelial Neoplasia
2013
OBJECTIVE: To evaluate the association of three patho-gnomonic criteria, inner border, ridge sign, and rag sign with high-grade cervical intraepithelial neoplasia (CIN) using video exoscopy. METHODS: Retrospective evaluation of video recordings of 335 patients, referred for diagnostic colposcopy, who underwent cervical biopsies, and, if indicated loop excisions, was performed. The most severe histologic diagnosis was recorded. Sensitivity, specificity, positive, negative predictive value, and likelihood ratios for highgrade CIN were calculated. RESULTS: In 285 patients (85%), a single colposcopy directed biopsy was taken; 50 patients (15%) underwent two biopsies. One hundred sixty-two patie…
Eleonora Duse's Library: The Disclosure of Aesthetic Value in Real Acting
2010
Even though Eleonora Duse (1858-1924) referred to her books as her own artistic wardrobe, her most highly valued possessions, scholars and biographers have insisted on neglecting her library and furthermore, have for many years considered it lost forever. This article explains the value of the founding and reconstructing of the Murray Edwards Eleonora Duse Collection in Cambridge. She specifically refers to a selection of books which have been renamed 'Cleopatra's Books'. They are remarkable examples which are representative of Duse's library as a whole and lay bare the roots of Duse's intellectual evolution. Many have believed the romantic notion that Duse acted out her own personal life o…
Coupling between agonist and chloride ionophore sites of the GABA(A) receptor: agonist/antagonist efficacy of 4-PIOL.
2000
Eight gamma-aminobutyric acid (GABA) mimetics were tested on their ability to differentiate native GABA(A) receptor subtypes present in various rat brain regions. In rat brain cryostat sections, little regional variations by the agonistic actions of muscimol, thiomuscimol, 4,5,6,7-tetrahydroisoazolo(5,4-c)pyridin-3-ol, piperidine-4-sulphonic acid, taurine and beta-alanine on [35S]t-butylbicyclophosphorothionate ([35S]TBPS) binding to GABA(A) receptor channels were found. They were very similar to those found for GABA itself and indicated no direct correlation with single subunit distributions for any of these compounds. Only the low-efficacy GABA mimetic 5-(4-piperidyl)isoxazol-3-ol (4-PIOL…
Behavioral effects of different enriched environments in mice treated with the cholinergic agonist PNU-282987.
2013
Abstract Environmental enrichment is an experimental model in which rodents are housed in complex environments that favor lower levels of anxiety-like behavior. PNU-282987 (PNU) is a α7 nicotinic acetylcholine receptor agonist with beneficial effects on learning though its effects on anxiety are unclear. Our main aim was to carry out a study of its effects in NMRI ( n = 96) mice reared in different environments: environmental enrichment (EE), Marlau™ cages (MC) and standard environment (SE). After a 4-month period, mice received acute treatment of PNU (2.5, 5 and 10 mg/kg) and were evaluated in the elevated plus-maze (EPM) and hole-board (HB). In the EPM, both EE and MC reared mice showed …
Exploring kainate receptor pharmacology using molecular dynamics simulations.
2010
Ionotropic glutamate receptors (iGluRs) are enticing targets for pharmaceutical research; however, the search for selective ligands is a laborious experimental process. Here we introduce a purely computational procedure as an approach to evaluate ligand–iGluR pharmacology. The ligands are docked into the closed ligand-binding domain and during the molecular dynamics (MD) simulation the bi-lobed interface either opens (partial agonist/antagonist) or stays closed (agonist) according to the properties of the ligand. The procedure is tested with closely related set of analogs of the marine toxin dysiherbaine bound to GluK1 kainate receptor. The modeling is set against the abundant binding data …
