Muscle architecture is an important component of muscle function, and recent studies have shown changes in muscle architecture with fatigue. The stretch-shortening cycle is a natural way to study human locomotion, but little is known about how muscle architecture is affected by this type of exercise. This study investigated potential changes in medial gastrocnemius (MG) muscle architecture after exhaustive stretch-shortening cycle exercise. Male athletes (n = 10) performed maximal voluntary contractions (MVC) and maximal drop jump (DJ) tests before and after an exercise task consisting of 100 maximal DJs followed by successive rebound jumping to 70% of the initial maximal height. The exerci…

Beurteilung der Durchgängigkeit von koronaren Bypassgefäßen mit einer 2D T2-gewichteten Turbo-Spin-Echo-Sequenz (HASTE) in Atemanhaltetechnik

1999

AIM To evaluate the patency of coronary artery bypass grafts with a 2D T2-weighted breath-hold turbo-spin-echo sequence. METHODS 38 patients with 97 grafts (19 internal mammary artery and 78 saphenous vein grafts) and a total of 120 distal anastomoses were studied at 1.5 Tesla in supine position using a phased array body coil. An ECG gated 2D T2-weighted breath-hold turbo-spin-echo sequence (HASTE) was performed. Reference method was selective coronary angiography. The image material was evaluated independently by two radiologists (observer one, a radiological fellow and the second a staff radiologist). RESULTS Observer 1 reached a sensitivity of 96% (72/75) and a specificity of 91% (20/22)…

Implant-specific follow-up imaging of treated intracranial aneurysms: TOF-MRA vs. metal artifact reduced intravenous flat panel computed tomography a…

2017

Aim To compare the diagnostic quality of time-of-flight magnetic resonance angiography (TOF-MRA) and metal-artefact-reduction (MAR) flat-panel-detector computed tomography angiography (FPCTA) and to determine the imaging technique best suited for evaluation endovascular and surgically treated aneurysms. Methods The image quality of TOF-MRA and MAR-FPCTA of 44 intracranial implants (coiling: n= 20; clipping: n= 15; coiling + stenting: n= 9) in a patient cohort of 25 was evaluated by two independent readers. Images obtained using MAR-FPCTA (20 second scan time, 496 projections, intravenous contrast medium administration; Artis Zee, Siemens Healthcare, Forchheim) were compared with TOF-MRA-ima…

Preliminary study of the neuromuscular activation during barefoot and shod running

2015

El objetivo del presente estudio preliminar fue comparar la actividad muscular de los músculos tibial anterior, peroneo lateral largo, gastrocnemio medial y gastrocnemio lateral entre la carrera con y sin calzado, y la influencia de la fatiga. 7 participantes realizaron una carrera de fatiga de 20 minutos al 75% de su velocidad aeróbica máxima en cinta con 1% de pendiente. Se midió la actividad mioeléctrica de los músculos antes mencionados tanto antes como después de la prueba de fatiga en dos condiciones: con calzado y sin calzado. Los resultados mostraron una mayor actividad del tibial anterior durante la carrera en fatiga descalzo respecto a la carrera calzado y una mayor actividad del …

Application of IPL technology in Acne Vulgaris treatment: a case report

2018

Background: Intense pulsed light (IPL) technology has been used by cosmetic and medical practitioner since 1990. Initially it was only used to remove unnecessary hair, but over time, it began to be used for anti-aging treatments, removing erythema, acne lesions, and acne scars. Aim of the study: The aim of this study is to investigate how the use of IPL technology has affected acne lesions and to determine whether the condition of the patient’s skin has improved. Material and methods: A young woman who was struggling with ordinary acne underwent a series of treatments using IPL technology to reduce skin eruptions. Results: The study subject was a 22-year-old patient who had been suffering f…

Abstract Background Clinical management ranges from surveillance or curettage to wide resection for atypical to higher-grade cartilaginous tumours, respectively. Our aim was to investigate the performance of computed tomography (CT) radiomics-based machine learning for classification of atypical cartilaginous tumours and higher-grade chondrosarcomas of long bones. Methods One-hundred-twenty patients with histology-proven lesions were retrospectively included. The training cohort consisted of 84 CT scans from centre 1 (n=55 G1 or atypical cartilaginous tumours; n=29 G2-G4 chondrosarcomas). The external test cohort consisted of the CT component of 36 positron emission tomography-CT scans from…

Evaluating resurfacing modalities in aesthetics.

2022

Abstract Skin resurfacing for cutaneous rejuvenation has evolved with the development of a plethora of nonsurgical and minimally invasive modalities. We have highlighted the advances in laser therapy, chemical peels, radiofrequency, microneedling, and platelet-rich plasma therapy. We have also included studies providing head-to-head comparisons between procedures and discussed relevant debates in the field. We have examined additionally combination treatments and resurfacing in acne scars, melasma, and skin of color.

Übereinstimmung von klinischer Beurteilung, Heidelberg-Retina-Tomograph (HRT) und Nerve Fiber Analyzer (GDx) in der Glaukomdiagnostik

2004

BACKGROUND We have made a comparison of clinical evaluation, Heidelberg-Retina-Tomograph (HRT) and Nerve Fiber Analyzer (GDx) in diagnosing glaucoma. MATERIALS AND METHODS One eye of 38 glaucoma patients and 26 non-glaucoma patients was examined with HRT and GDx. Assignment of the patients into the two groups by clinical evaluation was performed on the basis of visual field and optic disc results. As classification criterion for glaucoma/non-glaucoma by means of the instruments we employed the statistical classification of the HRT and "the number" of the GDx. Statistical analysis was performed with Cohen's kappa and McNemar tests. Additionally, ROC curves for evaluation of the sensitivity a…

Cranial nerve function in workers exposed to polychlorinated dioxins and furans

2002

OBJECTIVE: To look for possible effects of polychlorinated dioxins and furans (PCDD/F) on cranial nerve function. MATERIAL AND METHODS: Clinical and neurophysiological examinations [visual and brainstem auditory evoked potentials (VEP and BAEP), blink reflex] in 121 PCDD/F exposed workers of one pesticide producing plant. RESULTS: BAEP abnormalities were more frequent in workers with chloracne (6 of 33 workers, 18.2%) than in those without chloracne (7 of 84, 8.3%), but this was not statistically significant (chi2: 2.33). VEP abnormalities were seen in one worker with and two without chloracne. Clinically visual functions were normal except in one worker, who was amaurotic since birth. Blin…
