Background Sprint performance is an essential skill to target within soccer, which can be likely achieved with a variety of methods, including different on-field training options. One such method could be heavy resisted sprint training. However, the effects of such overload on sprint performance and the related kinetic changes are unknown in a professional setting. Another unknown factor is whether violating kinematic specificity via heavy resistance will lead to changes in unloaded sprinting kinematics. We investigated whether heavy resisted sled training (HS) affects sprint performance, kinetics, sagittal plane kinematics, and spatiotemporal parameters in professional male soccer players…

Acute estradiol protects CA1 neurons from ischemia-induced apoptotic cell death via the PI3K/Akt pathway

2010

Global ischemia arising during cardiac arrest or cardiac surgery causes highly selective, delayed death of hippocampal CA1 neurons. Exogenous estradiol ameliorates global ischemia-induced neuronal death and cognitive impairment in male and female rodents. However, the molecular mechanisms by which a single acute injection of estradiol administered after the ischemic event intervenes in global ischemia-induced apoptotic cell death are unclear. Here we show that acute estradiol acts via the phosphoinositide 3-kinase (PI3K)/protein kinase B (Akt) signaling cascade to protect CA1 neurons in ovariectomized female rats. We demonstrate that global ischemia promotes early activation of glycogen syn…

Value of serial magnetic resonance imaging in the assessment of brain metastases volume control during stereotactic radiosurgery

2016

AIM To evaluate brain metastases volume control capabilities of stereotactic radiosurgery (SRS) through serial magnetic resonance (MR) imaging follow-up. METHODS MR examinations of 54 brain metastases in 31 patients before and after SRS were reviewed. Patients were included in this study if they had a pre-treatment MR examination and serial follow-up MR examinations at 6 wk, 9 wk, 12 wk, and 12 mo after SRS. The metastasis volume change was categorized at each follow-up as increased (> 20% of the initial volume), stable (± 20% of the initial volume) or decreased (< 20% of the initial volume). RESULTS A local tumor control with a significant (P < 0.05) volume decrease was observed in 25 meta…

A common role for psychotropic medications: memory impairment.

2002

Summary The psychopathologic profile of mental disorders is very diverse and psychotropic medications used to treat them differ in their chemical structure. Nevertheless, these drugs share these four characteristics: delayed onset of clinical response, not one of them can be said to cure, there is a high number of non-responders, and the mechanism responsible for their therapeutic action is not known. It is hypothesized that the action of psychotropic medications is memory impairment, understanding memory as the trace left in the nervous system not only by individual experiences but also by genetic and epigenetic phenomena. It is suggested that it would be beneficial to translate some resea…

Behavioural treatment of improper eating by an institutionalised woman with profound intellectual disability—description of a successful intervention

2002

Intensive 11-day behavioural training of an institutionalised woman with profound intellectual disability was used to teach proper eating by reducing her eating errors. The methods used included an increased number of learning opportunities, graduated guidance, the use of social reinforcement, and mild punishment through simple correction of eating errors. The treatment was faded into a maintenance phase. After the intensive training phase, the participant ceased to eat with her fingers from a plate, and her eating changed to a more tidy habit. She was also released from having her hand tied during the meals. The results were maintained during an informal follow-up 4 years later.

Goals of Care in Emergency Abdominal Surgery in the Elderly and Frail Patient

2021

Elderly and frail patients are often those at highest risk during surgical procedures both in terms of intraoperative complications and postoperative outcome. It is clear that the best therapeutic result in the elderly and frail patient can be obtained through multidisciplinary management of the problem. In the management of elderly and frail patients undergoing to emergency surgery, we can make a series of considerations that guide our decision-making process. First, correct diagnosis can be difficult because of the impaired cognitive and physical status of the patient or other clinical conditions and medications that mask signs and symptoms. Second, the choice of the treatment to be carri…

Hemostasis in brain tumor surgery using the Aquamantys system

2014

Background: Adequate hemostasis in cranial and spinal tumor surgery is of paramount importance in neurosurgical practice. Generalized ooze bleeding from the surgical walls cavity, coming from neoplastic vessels or nervous tissue, may be problematic. Recent technical advances have dramatically reduced intraoperative complications related to blood loss. Several techniques are usually employed to control hemostasis in tumor surgery, including preoperative embolization, intraoperative hypotension, electrical coagulation, and local application of fibrin sealants or hemostatic matrix, which influence coagulation. Material/Methods: Our aim in this study was to evaluate the efficacy and the safety …

Emergency MRI in Clinical Peracute Brain Stem and Hemispheric Stroke

1998

We show the capability and results of MRI examinations of peracute brainstem and hemispheric stroke patients in clinical emergency situations. The hypothesis that CT scan is faster and more accurate under this conditions is to be disproved.

Brain Morphometry and Psychobehavioural Measures in Autistic Low-Functioning Subjects

1997

In the last two decades neurological research has significantly increased knowledge on the neuroanatomic bases of autism. Several autopsy and quantitative magnetic resonance imaging (MRI) studies have reported central nervous system (CNS) abnormalities which may underlie the social, language and cognitive dysfunction typical of the autistic disorder.Despite the wealth of evidence that the “autistic brain” is different from normal in a number of structures, the relationship between the severity of the developmental impairment in autism and the degree of the brain abnormality remains unknown.The aim of the present study is to correlate the areas of some brain regions, as calculated on the bas…

Unfavorable influence of structured exercise program on total leisure-time physical activity

2012

In randomized controlled trials (RCTs), with customized structured physical exercise activity (SPEA) interventions, the dose of leisure-time physical activity (LTPA) should exceed the LTPA dose of the nonexercising control (C) group. This increase is required to substantiate health improvements achievable by exercise. We aimed to compare the dose of SPEA, LTPA, and total LTPA (SPEA + LTPA) between a randomized Nordic walking (NW) group, a power-type resistance training (RT) group, and a C group during a 12-week exercise intervention in obese middle-aged men (n = 144) with impaired glucose regulation. The dose of physical activity was measured with diaries using metabolic equivalents. No sig…
