Inverse association between type 2 diabetes and aortic root dimension in hypertensive patients

2017

Background Some data support the concept that aortic root diameter (ARD) in hypertension may be regarded as a marker of subclinical organ damage. The impact of type 2 diabetes mellitus (DM) on cardiac structure and function is known, although the relationship between DM and ARD is not clear. The aim of our study was to evaluate the influence of DM on ARD in hypertensive patients. Methods We enrolled 1693 hypertensive patients (aged 63.7 ± 9.6 years). The population was divided into two groups: the first one with DM (n = 747) and the second one without DM (n = 946). ARD was measured by echocardiography at level of Valsalva's sinuses using echocardiography M-mode tracings. It was considered a…

However, the scientific literature shows mainly the theoretical information about their mutual connections. The lack of information about these …

The Rolf Method of Structural Integration and Pelvic Floor Muscle Facilitation: Preliminary Results of a Randomized, Interventional Study

2020

The management of pelvic floor dysfunctions might need to be based on a comprehensive neuro-musculoskeletal therapy such as The Rolf Method of Structural Integration (SI). The aim of the study was to evaluate the pelvic floor muscle (PFM) after the tenth session of SI by using surface electromyography (sEMG). This was a randomized, interventional study. Thirty-three healthy women were randomly assigned to the experimental (SI) or control group. The outcome measures included PFM bioelectrical activity, assessed using sEMG and endovaginal probes. An intervention in the SI group included 60 min of SI once a week, and teaching on how to contract and relax PFMs

The influence of the C1-inhibitor BERINERT® and the protein-free haemodialysate ACTIHAEMYL20%® on the evolution of the depth of scald burns in a porc…

1997

Standardized deep partial-thickness burns were inflicted on domestic pigs by scalding 30 per cent of the skin surface for 25 s with 75 degrees C hot water. The animals (n = 18; weight 25-35 kg) were divided into three groups: I, control group (n = 6), Ringer's lactate only; II, haemodialysate group (n = 6), Ringer's lactate and a protein-free haemodialysate of calf-blood (ACTIHAEMYL20%; AH) and III, C1-inhibitor group (n = 6), Ringer's lactate and C1-inhibitor (C1-INH; BERINERT). Skin biopsies were taken at defined time points (4, 28, 52 and 76 h) and investigated histologically. Depth of burn was determined morphometrically after coloration with a modified MTT-staining on frozen sections o…

New applicator improves waterjet dissection quality

2010

Waterjet dissection is accomplished with Helix Hydro-Jet, but a new device with improved operative handling and potentially superior dissection qualities has been developed.Eighty-four fresh cadaveric pig brains were simultaneously cut with Helix Hydro-Jet and Erbejet 2. A commonly used applicator and a new applicator for the Helix Hydro-Jet were directly compared to the new Erbejet 2. Under standardised conditions, different pressure levels were applied to the brain surface without arachnoids. Technical features, cutting depth, tissue damage and differences of applicators were examined.Microscopic analysis of cutting depth revealed different dissection characteristics of both the devices. …

Towards EEG-Based Haptic Interaction within Virtual Environments

2019

International audience; Current virtual environments (VE) enable perceiving haptic stimuli to facilitate 3D user interaction, but lack brain-interfacial contents. Using electroencephalography (EEG), we undertook a feasibility study on exploring event-related potential (ERP) patterns of the user's brain responses during haptic interaction within a VE. The interaction was flying a virtual drone along a curved transmission line to detect defects under the stimuli (e.g., force increase and/or vibrotactile cues). We found that there were variations in the peak amplitudes and latencies (as ERP patterns) of the responses at about 200 ms post the onset of the stimuli. The largest negative peak occu…

Use of a Virtual Environment to Engage Motor and Postural Abilities in Elderly Subjects With and Without Mild Cognitive Impairment (MAAMI Project)

2016

Objectives: In the context of rehabilitation, the use of new technology such as Virtual Reality Technology (VRT) offers multiple possibilities to modulate the functional stimulation of subjects according to needs. Material and methods: In this study, the validity and reliability of our VRT system were investigated in fifteen healthy aged adults (HAA) and seven aged subjects with mild cognitive impairment (MCI). One implicit session was designed through two virtual environments (VEs) in order to induce the adapted activities associated with balance and postural control. In comparison, the same activities were achieved in explicit sessions with a physiotherapist. This cross-over study made us…

Expression of differentiation antigens and growth-related genes in normal kidney, autosomal dominant polycystic kidney disease, and renal cell carcin…

1992

Cellular differentiation and mRNA levels of genes involved in kidney growth were investigated in normal kidney cells, cyst-lining epithelial cells of polycystic kidney disease, and renal carcinoma cells (RCC). All cells comparatively studied exhibited an antigenic phenotype of proximal tubular cells as shown by the expression of a panel of brush border membrane enzymes and kidney-associated cell surface antigens. The epithelial developmental antigen Exo-1 was expressed in 50% to 80% of cyst-lining epithelia in polycystic kidney tissue and in 20% to 30% of polycystic kidney cells cultured in vitro. Normal kidney cells and RCC were negative under identical culture conditions. The expression o…

Pedobarography: A Review on Methods and Practical Use in Foot Disorders

2021

Pedobarographic examination is a non-invasive method that enables the quantitative and qualitative evaluation of plantar pressure distribution, notably the plantar pressure distribution, referring to the function of the entire musculoskeletal system. This is a scoping review that aims to update knowledge on the practical use of pedobarography in foot disorders. We also attempted to systematize the methodological principles of conducting the pedobarographic examination. We searched Medline/PubMed, Embase, Web of Science, and the Cochrane Database of Systematic Reviews for the articles on the methodology of pedobarography. The search encompassed clinical trials, randomized controlled trials, …
