The Multi-States (MuSt) Theory for Emotion- and Action-regulation in Sports
2020
Feeling states – including emotional experiences – are fundamental to human adaptation, as they influence effort, attention, decision making, memory, and behavioural responses of individuals, as well as their interpersonal interactions. Thus, the ability to self-regulate is crucial for athletic success. This chapter presents the multi-states (MuSt) theory as a holistic approach for both emotion- and action-centred self-regulation for performance enhancement and optimisation. Central to the MuSt theory is the notion that a combination of emotion- and action-regulation strategies is more effective than focusing on one aspect alone. In this chapter, we describe psychobiosocial feeling states a…
Effects of Essential Hypertension on coronary Microcirculation: Focus on a Population of Hypertensives Affected by Microvascular Angina
2012
A correlation between essential hypertension and the establishmentof myocardial ischemia is nowadays universally accepted. Coronary atherosclerosis is deemed to be the most important process through which the capability of coronary district to supply a blood flow consistent with myocardial needs can be impaired, until the onset of an anginal syndrome. In this study, we verified whether hypertensives’ coronaries, seen by performing an angiographic study, are properly definable as normal, even in presence of an overt exertional angina, or if they should rather be barely defined as “macroscopically unharmed”, through the clues of a microvascular alteration
Fructose-1,6-Bisphosphate Protects Hippocampal Rat Slices from NMDA Excitotoxicity
2019
Effects of fructose 1,6-bisphosphate (F-1,6-P2) towards N-methyl-d-aspartate NMDA excitotoxicity were evaluated in rat organotypic hippocampal brain slice cultures (OHSC) challenged for 3 h with 30 &mu
The Mediating Effect of Different Exercise Programs on the Immune Profile of Frail Older Women with Cognitive Impairment.
2020
Background: Frail individuals experience an accelerated immunosenescence, and exercise has been identified as a therapy to promote a better inflammatory environment. Objective: To analyze the effects of 28-weeks of two different exercise protocols on the functional fitness and immune profiles of institutionalized pre-frail and frail women with mild cognitive impairment. Methods: Participants residing in care homes (n=60, 81±7.84 years old) were randomized into three groups: a chair elastic band muscle-strength exercise (CSE, n=21; 81±4.79), a chair multimodal exercise (CME, n=20; 80±8.19), and a control non-exercise (CGne, n=19; 80±10.01). Both CME and CSE groups performed progressive circ…
Lack of SCN1A Mutations in Familial Febrile Seizures
2002
Summary: Purpose: Mutations in the voltage-gated sodium channel subunit gene SCN1A have been associated with febrile seizures (FSs) in autosomal dominant generalized epilepsy with febrile seizures plus (GEFS+) families and severe myoclonic epilepsy of infancy. The present study assessed the role of SCN1A in familial typical FSs. Methods: FS families were selected throughout a collaborative study of the Italian League Against Epilepsy. For each index case, the entire coding region of SCN1A was screened by denaturant high-performance liquid chromatography. DNA fragments showing variant chromatograms were subsequently sequenced. Results: Thirty-two FS families accounting for 91 affected indiv…
Late gadolinium enhancement-cardiovascular magnetic resonance identifies coronary artery disease as the aetiology of left ventricular dysfunction in …
2009
Aims We evaluated the ability of late gadolinium enhancement (LGE) using cardiovascular magnetic resonance (CMR) to identify acute new-onset heart failure (HF) with left ventricular systolic dysfunction (LVSD), whether or not in relation to underlying coronary artery disease (CAD), in patients with no clinical evidence of associated ischaemic cardiomyopathy. Methods and results Hundred consecutive patients admitted with acute new-onset decompensated HF and EF ,40%, with no clinical or electrocardiographic data suggestive of CAD. The patients were classified according to the presence or absence of significant CAD (stenosis � 70% in at least one major vessel). Twenty-one patients (21%) had si…
Migraine, Cognitive Decline, and Dementia in Older Adults: A Population-Based Study
2022
Background: The potential impact of migraine on cognitive aging among older adults remains controversial. Objective: To examine the relationship of migraine and subtypes with cognitive decline and dementia in an older Swedish population. Methods: This population-based study included 3,069 participants (age ≥ 60 years) from the Swedish National study on Aging and Care in Kungsholmen, Stockholm. Baseline examination was conducted in 2001–2004, and participants were followed every 3 or 6 years until 2013–2016. Data were collected through face-to-face interviews, clinical examinations, laboratory tests, and linkage with registers. Global cognitive function was measured with the Mini-Mental Stat…
Heart-targeted overexpression of caspase3 in mice increases infarct size and depresses cardiac function
2001
Up-regulation of proapoptotic genes has been reported in heart failure and myocardial infarction. To determine whether caspase genes can affect cardiac function, a transgenic mouse was generated. Cardiac tissue-specific overexpression of the proapoptotic gene Caspase3 was induced by using the rat promoter of α-myosin heavy chain, a model that may represent a unique tool for investigating new molecules and antiapoptotic therapeutic strategies. Cardiac-specific Caspase3 expression induced transient depression of cardiac function and abnormal nuclear and myofibrillar ultrastructural damage. When subjected to myocardial ischemia–reperfusion injury, Caspase3 transgenic mice showed increased inf…
Estudio genético molecular del síndrome de Usher en España
2005
Usher syndrome (USH) associates deafness and retinitis pigmentosa (RP). It is a disease both clinically and genetically heterogeneous. It is inherited as an autosomal recessive trait and its prevalence makes it the most frequent association of hearing loss and RP. Clinically Usher syndrome is divided into type I (USH1), II (USH2) and III (USH3), according to the severity of hearing loss, age of onset of RP and the existence or not of vestibular dysfunction. There are at least 7 different localizations for USH1 and 5 genes have been identified. For USH2, 3 loci and 2 genes have been reported and USH3 is due to Clarin-1 gene. Our aim is to perform a clinical and genetic characterization of al…
Differential diagnosis problems in a patient with dysphonia and chronic lymphocytic leukemia
2014
SUMMARY Dysphonia is frequently an expression of laryngitis, especially when it comes in the evolution of an immunosuppressed patient, as happens in chronic lymphoproliferation. But other causes of dysphonia should also not be forgotten, including the possibility of new malignancies, especially due to the fact that these patients have genomic instability that predisposes to appearance of a second or even a third cancer. We present the case of a patient who developed dysphonia during chronic lymphocytic leukemia evolution. Its etiology was a mediastinal compression through lymph nodes, not linked to leukemia, but produced by metastases of a bronchopulmonary cancer, appeared recently. Dysphon…
