Brain BDNF Levels Elevation Induced by Physical Training is Reduced after Unilateral Common Carotid Artery Occlusion in Rats

2014

International audience; We investigated the contribution of blood flow elevation in the cerebrovasculature to physical training-induced brain-derived neurotrophic factor (BDNF) levels elevation in the brain. Brain-derived neurotrophic factor protein levels were measured in the motor cortex 24 h after the last session of a forced treadmill walking (30 minutes a day, 18 m/minute for 7 consecutive days). Unilateral common carotid artery occlusion and modulation of exercise intensity (0 versus -10% inclination of the treadmill) were used as strategies to reduce the (normal) elevation of flow in the cerebrovasculature occurring during exercise. Administration of N-nitro-L-arginine methyl ester (…

INTEGRATIVE APPROACH BETWEEN GENE VARIANTS, NEUROENDOCRINE EFFECTORS AND ANXIETY RESPONSE: A PILOT STUDY

2016

The aim of this study is to investigate the neurobiology of stress/emotionality, creating a multidisciplinary assessment model, which can help to provide psychological and physiological responses depending on the genetic background related to sport performances, social closeness and performance anxiety management in team sports. We enrolled 20 female volleyball players aged 13 ± 1 years old played in two different teams during a regional championship final. Saliva collection was carried out before and after the match. In order to evaluate the neuroendocrine effectors involved in stress and performance, we analyzed cortisol and progesterone levels through Elisa standard kit as well as HSP70 …

Sexually Dimorphic Behavioral Profile in a Transgenic Model Enabling Targeted Recombination in Active Neurons in Response to Ketamine and (2R,6R)-Hyd…

2020

Background: Rapid-acting antidepressants ketamine and (2R,6R)-hydroxynorketamine ((2R,6R)-HNK) have overcome some of the major limitations of classical antidepressants. However, little is known about sex-specific differences in the behavioral and molecular effects of ketamine and (2R,6R)-HNK in rodents. Methods: We treated mice with an intraperitoneal injection of either saline, ketamine (30 mg kg&minus

Ketogenic and Modified Mediterranean Diet as a Tool to Counteract Neuroinflammation in Multiple Sclerosis: Nutritional Suggestions.

2022

Ketogenic Diet is a nutritional pattern often used as dietotherapy in inflammatory diseases, including neurological disorders. Applied on epileptic children since 1920, in recent years it has been taken into account again as a tool to both reduce inflammatory burdens and ameliorate the nutritional status of patients affected by different pathologies. Multiple sclerosis (MS) is considered an immune-mediated neuro-inflammatory disease and diet is a possible factor in its pathogenesis. The aim of this work is to investigate the main potential targets of MS-related impairments, in particular the cognitive deficits, focusing on the alteration of biomarkers such as the Brain Derived-Neurotrophic …

Lactate Threshold Training Program on Patients with Multiple Sclerosis: A Multidisciplinary Approach

2021

Physical activity could play a key role in improving the quality of life, particularly in patients with nervous system diseases such as multiple sclerosis (MS). Through lactacid anaerobic training, this study aims to investigate the effects at a bio-psycho-physical level to counteract the chronic fatigue associated with the pathology, and to improve mental health at a psychological and neurotrophic level. Eight subjects (age: 34.88 ± 4.45 years) affected by multiple sclerosis were involved. A lactate threshold training program was administered biweekly for 12 weeks at the beginning of the study (T0), at the end of the study (T1) and at 9 months after the end of the study (T2), with physical…

ATTIVITA’ FISICA LATTACIDA IN SOGGETTI AFFETTI DA SCLEROSI MULTIPLA: UN MODELLO DI ANALISI INTERDISCIPLINARE

La qualità della vita è considerata un prodotto derivante da benessere fisico, mentale e sociale e può ovviamente essere compromessa in soggetti affetti da sclerosi multipla (SM), malattia autoimmune cronica demielinizzante che può presentare disturbi abbastanza variegati. Oggetto della presente tesi di dottorato è stato quello di testare un modello di approccio interdisciplinare che possa migliorare la qualità della vita nei pazienti affetti da SM, attraverso la promozione dell'attività fisica, considerando i benefici indotti dalla stessa sullo stato di salute sia fisico che mentale dei pazienti affetti da questa patologia. Particolare attenzione è stata rivolta alla valutazione dei fattor…
