Obstructive sleep apnea and Alzheimer’s disease-related cerebrospinal fluid biomarkers in mild cognitive impairment

2020

Abstract Previous studies have demonstrated that sleep-breathing disorders, and especially obstructive sleep apnea (OSA), can be observed in patients with a higher risk of progression to Alzheimer’s disease (AD). Recent evidence indicates that cerebrospinal fluid (CSF) AD-biomarkers are associated with OSA. In this study, we investigated these associations in a sample of patients with mild cognitive impairment (MCI), a condition that is considered the first clinical phase of AD, when patients showed biomarkers consistent with AD pathology. A total of 57 patients (mean age = 66.19; SD = 7.13) with MCI were included in the study. An overnight polysomnography recording was used to assess objec…

Factores de rendimiento en el desplazamiento del tenista influenciados por el calzado. (Performance factors on tennis player displacements influenced…

2009

Los desplazamientos laterales son de gran importancia en el tenis. Sin embargo, no ha sido publicado ningun estudio sobre el efecto del calzado sobre el rendimiento en este tipo de movimientos. En el estudio participaron 5 jugadores habituales de tenis y se analizaron 10 calzados comerciales de tenis. El movimiento estudiado consistio en un desplazamiento lateral con parada y cambio de sentido, registrandose las fuerzas mediante una plataforma dinamometrica Dinascan-IBV y grabandose el movimiento con dos camaras de video S-VHS Panasonic WV-BL600. Los resultados de los ANOVAs realizados mostraron que algunas de las variables analizadas eran dependientes del calzado (p < 0.05). De estas, dest…

Differences in sedentary time and physical activity among mothers and children using a movement-to-music video program in the home environment: a pil…

2016

Measured objectively, less than a quarter of adults and under half of preschool children in Finland meet the physical activity recommendations. Moreover, higher sedentary time among parents (such as watching television) is associated with higher sedentary time of their children. The study introduces an intervention based on reducing sedentary behavior among mothers and their children. It utilizes a combination of music and exercise via a motivation-targeting movement-to-music video program in the home environment. Data were collected in summer 2014 from Finland’s Pirkanmaa region. Each mother–child pair (n = 24, child age: 4–7 years) was assigned to the intervention and control group. Both …

Effects of obesity on periodontal tissue remodeling during orthodontic movement.

Made available in DSpace on 2021-06-25T15:01:37Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-04-01 Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP) German Research Foundation (DFG) Introduction: Orthodontic movement triggers a sequence of cellular and molecular events that may be affected by different systemic conditions. This study evaluated the effect of obesity on rat periodontal tissue remodeling induced by mechanical orthodontic force. Methods: Thirty-two Holtzman rats were distributed into 4 groups: control, obesity induction (O), orthodontic movement (M), and obesity induction and orthodontic movement (OM). Obesity was induced by a high-fat diet for 90 days. Af…

Type II diabetics with macrovascular complications: polymorphonuclear leukocyte (PMN) filtration, PMN membrane fluidity and cytosolic Ca2+ content af…

1998

We evaluated polymorphonuclear (PMN) filtration parameters, membrane fluidity and cytosolic Ca2+ content in 21 normal subjects and in 18 type II diabetics with macrovascular complications (MVC). Evaluations were carried out at baseline and after in vitro activation prolonged for 5 and 15 min. PMA (4-phorbol 12-myristate 13-acetate) and fMLP (N-formyl-methionyl-leucyl-phenylalanine) were used as stimulating agents. TMA-DPH (1-[4-(trimethylamino)phenyl]-6-phenyl-1,3,5-hexatriene) was used as fluorescent probe for the membrane fluidity tests and Fura 2-AM for the cytosolic Ca2+ content. A significant variation was evident in PMN filtration parameters at 5 and 15 min. No variation was present i…

Eye Kinematics of Athletes in Non-Familiar Sports Situations

2008

Biological motion can hardly be imitated, starting from how a person observes and learns motor behaviour. We recorded eye movements of 13 female ball games athletes and 13 age-matched controls observing videos of unfamiliar sports. The athletes are better at alternating between faster and slower eye movement modalities. They initially use longer but fewer fixations than the non-athletes.

Evaluation of movement and brain activity

2021

Clinical neurophysiology studies can contribute important information about the physiology of human movement and the pathophysiology and diagnosis of different movement disorders. Some techniques can be accomplished in a routine clinical neurophysiology laboratory and others require some special equipment. This review, initiating a series of articles on this topic, focuses on the methods and techniques. The methods reviewed include EMG, EEG, MEG, evoked potentials, coherence, accelerometry, coherence, posturography (balance), gait, and sleep studies. Functional MRI (fMRI) is also reviewed as a physiological method that can be used independently or together with other methods. A few applicat…

Lack of Accredited Clinical Training in Movement Disorders in Europe, Egypt, and Tunisia.

2020

BACKGROUND: Little information is available on the official postgraduate and subspecialty training programs in movement disorders (MD) in Europe and North Africa.OBJECTIVE: To survey the accessible MD clinical training in these regions.METHODS: We designed a survey on clinical training in MD in different medical fields, at postgraduate and specialized levels. We assessed the characteristics of the participants and the facilities for MD care in their respective countries. We examined whether there are structured, or even accredited postgraduate, or subspecialty MD training programs in neurology, neurosurgery, internal medicine, geriatrics, neuroradiology, neuropediatrics, and general practic…

Acute reversible parkinsonism in a diabetic-uremic patient.

2005

Acute movement disorders with basal ganglia lesions have been recently described in diabetic-uremic patients of Asian descent. The process is often reversible, with a favourable clinical outcome. Metabolic (i.e. uremic toxins) and microangiopathic changes have been suggested to be involved in its pathophysiology, even though racial and/or genetic factors might play a role too. In this report, we present a Caucasian diabetic patient with a long-lasting mild uremia in which acute parkinsonism occurred after a steep and unexpected increase of the serum creatinine. The follow-up demonstrated a significant improvement of the neurological signs and symptoms, the creatinine level lowered close to …
