Studies of the effects of physical activity on cognition suggest that aerobic fitness can improve cognitive abilities. However, the physiological mechanisms for the cognitive benefit of aerobic fitness are less well understood. We examined the association between aerobic fitness and cerebrovascular function with neurocognitive functions in healthy, young adults. Participants aged 18-29 years underwent measurements of cerebral vasomotor reactivity (CVMR) in response to rebreathing-induced hypercapnia, maximal oxygen uptake (VO2 max) during cycle ergometry to voluntary exhaustion, and simple- and complex-neurocognitive assessments at rest...

Chronic kidney disease affects more than 10% of the population. Programming studies have examined the interrelationship between environmental factors in early life and differences in morbidity and mortality between individuals. A number of important principles has been identified, namely permanent structural modifications of organs and cells, long-lasting adjustments of endocrine regulatory circuits, as well as altered gene transcription. Risk factors include intrauterine deficiencies by disturbed placental function or maternal malnutrition, prematurity, intrauterine and postnatal stress, intrauterine and postnatal overnutrition, as well as dietary dysbalances in postnatal life...

OBJECTIVE: Previous studies have demonstrated the importance of intensive optimal medical therapy (OMT) in patients with coronary artery disease (CAD). To investigate our hypothesis that patients with and without OMT achievement differed with respect to the risk of future cardiac events, we investigated the endothelial function in patients with CAD who underwent percutaneous coronary intervention (PCI) and contemporary medical therapy. METHODS: We conducted a prospective longitudinal cohort study to evaluate the endothelial function in 96 consecutive patients at 12 h after admission and 3 months at <12 h after admission and at 3 months after discharge by measuring the brachial artery dilatation after 5 min of forearm ischemia flow-mediated dilation (FMD)...

: Cancer patients are commonly associated with various physical and psychological symptoms. In view of this matter, palliative care is usually given to relieve those symptoms, improve quality of life, and increase medication adherence. Antidepressants are generally accepted for the treatment of depression among patients with or without cancer. Some other potential benefits of these medications have been experienced in clinical practice. Therefore, this study aimed to review the use of antidepressant for physical and psychological symptoms in cancer...

BACKGROUND: Humans are continuously exposed to particles in the gastrointestinal tract. Exposure may occur directly through ingestion of particles via food or indirectly by removal of inhaled material from the airways by the mucociliary clearance system. We examined the effects of food-grade particle exposure on vasomotor function and systemic oxidative stress in an ex vivo study and intragastrically exposed rats. METHODS: In an ex vivo study, aorta rings from naïve Sprague-Dawley rats were exposed for 30 min to food-grade TiO2 (E171), benchmark TiO2 (Aeroxide P25), food-grade vegetable carbon (E153) or benchmark carbon black (Printex 90)...

BACKGROUND: Ischemia-reperfusion (IR) injury impairs microcirculatory function by reducing nitric oxide (NO) bioavailability and increasing sympathetic tone. This study non-invasively examined the effects of acute upper limb IR injury on local thermal hyperemia (LTH) in glabrous and non-glabrous finger skin. MATERIALS AND METHODS: In ten healthy males, LTH was examined twice (~7-10 d apart) for each skin type on the index finger using laser-Doppler flowmetry in a counterbalanced design with either 1) 20 min ischemia, followed by reperfusion (ISCH) or 2) time-matched control (SHAM)...

Impaired ovarian function and menopausal symptoms are common after cancer treatment. Menopausal symptoms often occur at an earlier age in women with cancer, and may be more severe than in natural menopause; they may be the most persistent and troubling sequelae of cancer. A third of female patients with cancer report dissatisfaction with the quality and length of physician-patient discussions about reproductive health, including menopause. Systemic menopausal hormone therapy is the most effective treatment for menopausal symptoms, but it is not suitable for all patients after cancer - where it is unsuitable, alternative effective non-hormonal treatments are available...

OBJECTIVE: Mice with global null mutation of Ceacam1 (Cc1-/-), display impairment of insulin clearance that causes hyperinsulinemia followed by insulin resistance, elevated hepatic de novo lipogenesis, and visceral obesity. In addition, they manifest abnormal vascular permeability and elevated blood pressure. Liver-specific rescuing of Ceacam1 reversed all of the metabolic abnormalities in Cc1-/-liver+ mice. The current study examined whether Cc1-/- male mice develop endothelial and cardiac dysfunction and whether this relates to the metabolic abnormalities caused by defective insulin extraction...

Sutton and Clauss presented a detailed review about the effectiveness of zolpidem, discussing recoveries from brain damage due to strokes, trauma and hypoxia. A significant finding has been the unexpected and paradoxical increment of brain activity in vegetative state/unresponsive wakefulness syndrome (VS/UWS). On the contrary, zolpidem is considered one of the best sleep inducers in normal subjects. We have studied series of VS/UWS cases after zolpidem intake. We have demonstrated EEG activation, increment of BOLD signal in different brain regions, and an autonomic influence, mainly characterized by a vagolytic chronotropic effect without a significant increment of the vasomotor sympathetic tone...

Both patients with non-ischaemic systolic heart failure and patients with type 2 diabetes (T2DM) often have reduced myocardial blood flow without significant coronary atherosclerosis. However, the mechanisms are not fully understood. The aim of this study was to investigate whether perfusion is reduced additionally when the 2 are combined. In a cross-sectional study, we scanned patients with non-ischaemic systolic heart failure with and without T2DM using Rubidium-82 positron emission tomography/computed tomography at rest and adenosine-induced stress, thereby obtaining the myocardial flow reserve (myocardial flow reserve (MFR) = stress flow/rest flow) as a measure of the myocardial vasomotor function; 28 patients with T2DM and 123 without T2DM were included...

Reduced clearance of lipoproteins by HDL scavenger receptor class B1 (SR-B1) plays an important role in occlusive coronary artery disease. However, it is not clear how much microvascular dysfunction contributes to ischemic cardiomyopathy. Our aim was to determine the distribution of vascular dysfunction in vivo in the coronary circulation of male mice after brief exposure to Paigen high fat diet, and whether this vasomotor dysfunction involved nitric oxide (NO) and or endothelium derived hyperpolarization factors (EDHF)...

Androgen deprivation therapy (ADT) is the mainstay of treatment of patients with relapsed or metastatic hormone-sensitive prostatic carcinoma. The dramatic reduction of serum testosterone levels induced by ADT produces multiple side effects as vasomotor flushing, sexual dysfunction, fatigue, impairment of cognitive function, reduced quality of sleep, gynecomastia and anemia, that are able to decrease health-related quality of life (QoL). In addition, hormonal therapy can interfere with bone metabolism and induce metabolic and cardiovascular complications...
