Determination of milk production losses and variations of fat and protein percentages according to different levels of somatic cell count in Valle de…
2018
The somatic cell count (SCC) of milk is widely used to monitor udder health and the milk quality and because of its positive genetic correlation with mastitis this trait was included in breeding schemes of dairy sheep. The aim of this study was to estimate the loss in milk yield (MY) and related composition resulting from different levels of somatic cell count in Valle del Belice dairy sheep. Data were collected between 2006 and 2016 in 15 flocks following an A4 recording scheme. Somatic cell count (SCC), fat and protein percentage (F% and P%) were determined using mid-infrared spectroscopy. To evaluate loss in test day MY, F% and P%, five different classes of SCC were arbitrarily defined: …
The effect of visual motion stimulus characteristics on vection and visually induced motion sickness
2019
Abstract Several factors contribute to the likelihood of experiencing illusory sensations of self-motion (i.e., vection) in Virtual Reality (VR) applications. VR users can also experience adverse effects such as disorientation, oculomotor issues, or nausea known as visually induced motion sickness (VIMS). The goal of the present study was to systematically investigate three characteristics of visual motion stimuli—speed, density, and axis of rotation—and how they relate to both vection and VIMS. Two experiments were conducted. In Experiment 1, a stereoscopic stimulus containing a star field of white spheres on a black background was presented to 21 participants. The stimulus contained linea…
Pulsed electromagnetic field therapy in the treatment of pain and other symptoms in fibromyalgia: A randomized controlled study
2018
Low-energy pulsed electromagnetic field (PEMF) therapy has been suggested as a promising therapy to increase microcirculation, which is of great concern in patients with fibromyalgia. This study evaluated the effectiveness of PEMF therapy on the treatment of fibromyalgia. A group of 108 women with fibromyalgia were allocated to a 12-week treatment period with an active Bio-Electro-Magnetic-Energy-Regulation (BEMER) device and a similar treatment period with an inactive device. Each patient received active and sham treatments in a random order. Pain and stiffness were assessed on a visual analog scale (VAS, scale 0-100 mm), and functional status was assessed by the Fibromyalgia Impact Questi…
THU0520 Assessment of cardiovascular risk in patients with fibromyalgia by carotid-femoral pulse wave velocity – results of a prospective study
2018
Background Autonomic dysfunction, a basic element of fibromyalgia (FM), has been in some cases related to increased risk of cardiovascular (CV) disease. CV risk associates with aortic stiffness, which can be reliably assessed by carotid-femoral pulse wave velocity (cfPWV). Objectives Aims of this study were to test the hypothesis of increased cfPWV in a group of patients with FM and to examine its association with FM associated parameters and selected traditional CV risk factors. Methods We performed measurements of cfPWV in 99 FM patients and 102 healthy controls. The difference between cfPWV values in the two groups after controlling for possible confounding factors was evaluated through …
The effects of fractional CO2 laser, Nano-hydroxyapatite and MI paste on mechanical properties of bovine enamel after bleaching
2017
Background This study investigated the effect of post bleaching treatments to the change of enamel elastic modulus and microhardness after dental bleaching in- vitro. Material and Methods Fifty bovine incisor slab were randomly assigned into five groups (n=10). The samples were bleached for three times; 20 minutes each time, by 40% hydrogen peroxide. Next it was applied fractional CO2 laser for two minutes, Nano- hydroxy apatite (N-HA) and MI-paste for 7 days and 2 minutes per day. The sound enamel and bleached teeth without post treatment remained as control groups. The elastic modulus and microhardness were measured at three times; 24 hours, 1 and 2 months. Data were statistically analyze…
El diagnóstico de la crisis de la cultura en España: del recorte público a la crisis sistémica
2016
Since its invention in the fifties, cultural policy has been subject of analysis and reflection by Social Sciences. However, Spain, due to Franco period, has a number of distinguishing features as compared to Western European democracies. With the restoration of democracy, Spain acquires the dominant paradigm of a democratic cultural policy based on freedom, pluralism and the right to culture. However, after decades of democratic governments, diagnosis of cultural policy in Spain shows signs of systemic crisis, added to the impact of the global financial crisis at the beginning of the XXI century. In this context, scholars, using the Delphi method along with secondary sources, identify a se…
Type of surgery is associated with pain and walking difficulties among older people with previous hip fracture
2015
Aim The aim was to assess the level of lower body pain among people with previous femoral neck fracture, and whether the type of surgery was associated with pain and physical function a mean of 2 years after surgery. Methods The study included 115 community-dwelling older adults aged 60 years and older with previous femoral neck fracture, and 31 reference subjects without previous lower limb injuries. A total of 30 patients had internal fixation surgery, 70 had hemiarthroplasty and 15 had total hip replacement. All patients had surgery in the same hospital and received typical inpatient rehabilitation. From 1.6 months to 7.5 years after the fracture, the patients underwent examination inclu…
Can hip resurfacing be safely revised with short-stem total hip arthroplasty? A case series of six patients.
2021
Abstract Background The usage of short stems in primary total hip arthroplasty (THA) has constantly gained popularity over the last decade, however, to date, short stems are not eligible to be used as revision implants. The aim of this study was to retrospectively evaluate the outcome of revision surgery of failed hip resurfacing arthroplasty (HRA) using short-stem THA. Methods In a single center, retrospective analysis, 6 consecutive patients who were treated with a calcar-guided short stem after failure of HRA were evaluated. The mean follow-up was 3.25 years (SD 0.45). Patient reported outcome measurements (PROMs) were recorded using the Harris hip score (HHS) and The Western Ontario and…
Arthroscopic Reinsertion of Acute Injuries of the Scapholunate Ligament Technique and Results
2020
Abstract Objective To describe a technique for treating acute injuries of the scapholunate ligament (SLL) by performing an arthroscopic reinsertion of the SLL and dorsal capsulodesis and to present the results obtained. Methods The study deals with an analytical, prospective clinical study that included 19 consecutive patients with acute injury of the SLL. The range of joint motion, grip strength, pain according to the visual analog scale, functional outcomes according to the Mayo Wrist Score (MWS), and the QuickDASH Score were studied preoperatively and 6 and 12 months postoperatively. The complications and necessary reinterventions were recorded. Results Nineteen patients with acute injur…
Traditional process: influence on sensory properties and on consummers' expectation and liking application to "pâté de campagne"
2000
Abstract Sensory profiling of eight ‘pâtes de campagne’, of which four were produced according to a traditional process and four produced according to a non traditional process, was performed by a trained panel. Results revealed some sensory particularities of each process but also sensory differences among the eight products which were not related to the process. Expectations created by two labels, one evoking a traditional and one evoking a non traditional process for ‘pâte de campagne’, were determined for 125 consumers. The impact of these expectations on expectation after visual examination and on liking after tasting was also studied, using the same eight products. The impact of infor…
