The effects of three different training protocols on beginners in eight weeks

2012

The aim of this study was to compare three different methods of training in order to determine the effectiveness on weight loss in relation to body composition in adults. One hundred subjects aged 18 to 38 years, with a BMI equal to or greater than 27 and a body fat percentage greater than 22% for women and 12% for men, were enrolled in this study. They were subdivided into 3 groups that followed a different protocol. Before to start the training protocols was detected the starting level of fitness by a test of maximal oxygen consumption, VO2 max and maximal strength tests that it was detected by one maximal repetition of the major muscle groups; this has allowed to draw up personalized tra…

MULTIPLE SCLEROSIS: PHYSICAL ACTIVITY AND WELL-BEING

2017

Multiple sclerosis (MS) is a chronic disease that affects central nervous system (CNS) – coexists in brain, spinal cord and optic nerves. It can process in three different courses: remitting, progressive and progressive-relapsing. Although there is still no cure for MS, effective strategies are available to modify the disease course, reduce number of relapses, rate of progressions and development of new lesions. Nowadays, moderate physical performance is strongly recommended: besides having positive effects on the body, it can have a positive effect on the psychophysical wellbeing. Essentially there are 3 types of training protocols: aerobic (endurance training), strength training (resistan…

A radical signal activates the epigenetic regulation of longevity

2013

Hormesis is an adaptive stress response implicated in longevity regulation. Schroeder et al. (2013) have now connected stress, epigenetic changes, and aging in yeast by showing that mitochondria-derived reactive oxygen species modulate the chromatin binding capacity of the histone demethylase Rph1p at subtelomeres, resulting in lifespan extension.

ADIPOSE TISSUE-TARGETED STEM CELL TRANSPLANTATION FOR INSULIN RESISTANCE-RELATED CNS DEFICITS

Compelling evidence indicates that Type 2 Diabetes (T2D) and Alzheimer’s Disease (AD) may possibly share a common pathological origin, but the underlying mechanisms remain poorly understood. T2D is a known risk factor for AD and insulin resistance (hallmark of T2D) has been extensively documented in AD patients. Notably, insulin is important for learning and memory due to its role in LTP and LTD modulation. Adipose tissue (AT) dysfunction is a risk factor for T2D, in fact elevated levels of free fatty acids are prodromal to insulin resistance and have been reported in AD brains, as well. In this study, I used a mouse model (AtENPP1Tg mouse) that recapitulates typical characteristics of huma…

INFLUENCE OF POSIDONIA OCEANICA MEADOW DENSITY ON FLOW RESISTANCE IN SHALLOW WATERS

2008

Aquatic vegetation considerably affects circulation in water bodies with influence increasing as the depth decreases. On the other hand, increasing use of mathematical circulation models for management of coastal sea waters, lagoons and marshes requires determination of such effects and in particular of flow resistance. A typical plant of inshore sandy beds, less than 40 m deep, in the Mediterranean Sea is Posidonia oceanica, which is constituted by a tuft of very thin and flexible ribbon-like leaves about 1 cm wide and up to 1.5 m long. This plant forms meadows with areal density usually ranging between 500 and 1000 plants/m2. Because of its characteristics, Posidonia oceanica constitutes …

Membrane Fouling Mitigation in MBR via the Feast–Famine Strategy to Enhance PHA Production by Activated Sludge

2022

Fouling is considered one of the main drawbacks of membrane bioreactor (MBR) technology. Among the main fouling agents, extracellular polymeric substances (EPS) are considered one of the most impactful since they cause the decrease of sludge filterability and decline of membrane flux in the long term. The present study investigated a biological strategy to reduce the membrane-fouling tendency in MBR systems. This consisted of seeding the reactor with activated sludge enriched in microorganisms with polyhydroxyalkanoate (PHA) storage ability and by imposing proper operating conditions to drive the carbon toward intracellular (PHA) rather than extracellular (EPS) accumulation. For that purpos…

Fatigue resistance: is it possible having a unique response?

2012

The mechanical characterisation of the asphalt concrete in terms of both the fatigue resistance and the stiffness modulus is necessary to use any design method of the flexible road pavements. Different kinds of test are usually used in experimental work such as bending tests, uniaxial tests, etc., but sometimes they do not give the same answer. In this paper mechanical characterization was carried out by means of fatigue tests undertaken with two most used testing machines for asphalt material: two point bending (2PB) test at IFSTTAR in Nantes (France) and four point bending (4PB) test at University of Palermo, in Palermo (Italy). Different strain controlled tests were undertaken for the sa…

Rolling resistance and traffic delay impact on a road pavement life cycle carbon footprint analysis

2017

The application of Life Cycle Assessment (LCA) to road pavements has been continuously evolving and improving over the last years, however there are several limitations and uncertainties in the introduction of some components in the framework, such as road pavement rolling resistance—in terms of pavement surface properties—and traffic delay during maintenance activities. This paper analyses the influence of methodological assumptions and the model used to estimate the increased emissions for traffic delay and road pavement rolling resistance on the results of an LCA. The Greenhouse Gases (GHG) emissions related to these two phases of a pavement LCA will be calculated for a UK case study, us…
