Comparison of 2 Doses of Intravenous (IV) Temsirolimus (Temsr) in Patients with Relapsed/Refractory Mantle Cell Lymphoma (MCL)
2016
Abstract Introduction: Temsr (Torisel®) administered at 175 mg IV once weekly for first 3 weeks, followed by 75mg IV once weekly (Temsr 175/75 mg) is approved in the European Union for the treatment of adult patients with relapsed and/or refractory MCL based on an overall positive benefit-risk relationship demonstrated for this treatment regimen in the pivotal phase III study (Hess et al. J Clin Oncol. 2009;27:3822-9). This ongoing phase 4, multicenter, randomized, open-label study was conducted to explore whether similar efficacy can be achieved for the treatment of patients with relapsed/refractory MCL with a Temsr regimen that is expected to yield fewer side effects than the Temsr 175/75…
The Stretch-Shortening Cycle
2006
Neuromuscular fatigue has traditionally been examined using isolated forms of either isometric, concentric or eccentric actions. However, none of these actions are naturally occurring in human (or animal) ground locomotion. The basic muscle function is defined as the stretch-shortening cycle (SSC), where the preactivated muscle is first stretched (eccentric action) and then followed by the shortening (concentric) action. As the SSC taxes the skeletal muscles very strongly mechanically, its influence on the reflex activation becomes apparent and very different from the isolated forms of muscle actions mentioned above. The ground contact phases of running, jumping and hopping etc. are example…
Effects of power training on neuromuscular performance and mechanical efficiency
2007
Effects of power training with stretch-shortening cycle (SSC) exercises on mechanical efficiency (ME) were investigated with 9 young women who trained 3 times a week for 4 months. The training included various types of jumping exercises. Before and after the training as well as after the detraining (2 months) the subjects performed 6 different submaximal exercises with a special sledge apparatus. Each exercise involved 60 muscle actions lasting for a total of 3 min per testing condition. The work intensities were determined individually according to the recordings of distance obtained during the single maximal concentric exercises. The training caused the greatest changes of ME in condition…
Interaction between muscle stiffness and stretch reflex sensitivity after long-term stretch-shortening cycle exercise
1998
The short latency stretch-reflex component (M1) and its interactions with muscle stiffness and with muscle performance were investigated before and after long-term stretch-shortening cycle (SSC) exercise. Dramatic fatigue induced reduction in maximal SSC performance capability, and electromyographic activity was accompanied by a consistent decrease in the M1 reflex component and eccentric peak stiffness of the muscle. It can be suggested, therefore, that the decreased muscle performance is not simply a direct effect of central or peripheral fatigue, but is partly due to impairment of the ability to utilize stiffness-related elastic energy.
Muscle conduction velocity, strength, neural activity, and morphological changes after eccentric and concentric training
2014
This study compared the effects of concentric and eccentric training on neuromuscular adaptations in young subjects. Twenty-two men and women were assigned to one of two groups: concentric (CON, n = 11) and eccentric (ECC, n = 11) training. Training consisted of 6 weeks of isokinetic exercise, performed twice weekly, starting with two sets of eight repetitions, and progressing to five sets of 10 repetitions. Subjects were tested in strength variables [concentric, eccentric, and isometric peak torque (PT), and rate of force development (RFD)], muscle conduction velocity (CV), neuromuscular activity, vastus lateralis (VL) muscle thickness, and echo intensity as determined by ultrasonography. …
Analysis of the antibiotic prophylaxis prescribed by Spanish oral surgeons
2009
Aim: To identify prophylactic antibiotic prescription practices among Spanish dentists with preferential dedication to Oral Surgery in different types of tooth extraction surgeries. Method: Members of the Spanish Oral Surgery Society were surveyed on antibiotic prophylaxis use in 4 different tooth extraction modalities scaled according to their surgical invasiveness. Results: Sixty-nine of the 105 distributed questionnaires were returned completed. Thirteen percent of the surveyed surgeons would prescribe antibiotics to prevent postoperative wound infection when confronted with conventional tooth extraction lasting less than 5 minutes. In the case of surgery lasting more than 5 minutes, the…
Differences in myoelectric activity of the lumbar muscles between recurrent and chronic low back pain: a cross-sectional study
2021
Abstract Background Altered lower back muscle activity is proposed as a contributing factor to the reoccurrence and chronicity of low back pain (LBP). This study compared lumbar muscle activity during trunk extension in patients with continuous chronic LBP (CLBP), non-continuous CLBP, recurrent LBP (RLBP) and healthy subjects. Methods In 75 subjects (16 continuous CLBP, 15 non-continuous CLBP, 23 RLBP, 21 healthy controls), surface electromyographic (EMG) activity of the lumbar erector spinae (ES), multifidus (MF), latissimus dorsi (LD) and gluteus maximus (GM) was recorded during the concentric, holding and eccentric phase of a modified Biering Sorenson exercise. Results Continuous CLBP pa…

La configuración constitucional del medio ambiente como derecho
2016
La aparición del derecho al medio ambiente se produce por la toma de conciencia del deterioro del entorno por causas antrópicas. El entorno influye en los seres humanos y condiciona los modelos sociales, la cultura o los modelos urbanos. Así mismo, el hombre influye en el medio a través, igualmente, de la cultura y los modelos sociales, pero de forma inmediata y con más intensidad a partir del siglo XIX por la actividad agrícola e industrial que se produce como consecuencia de la Revolución industrial. El modelo de producción que se instaura a partir de ese momento trajo como consecuencia un manifiesto deterioro ambiental. Frente a esta agresión ambiental, con repercusiones en la salud ambi…
Descubriendo nuevos antibióticos producidos por bacterias del suelo
2019
El abuso y/o uso inadecuado de antibióticos es actualmente un grave problema en nuestra sociedad que hace que los microorganismos adquieran resistencias frente a estos compuestos antimicrobianos. Estas resistencias son debidas a la presión de selección que ejercemos sobre los microorganismos, lo que dificulta el tratamiento de las enfermedades que causan algunos de ellos. Por lo tanto, se hace necesario la búsqueda de nuevos antibióticos mediante distintas estrategias, siendo una de ellas la relacionada con la participación ciudadana. El objetivo principal del presente proyecto, basado en una estrategia de Aprendizaje-Servicio (ApS), se ha centrado en la realización de una propuesta educati…
