Quantitative and Qualitative tools for a physical education program that increases inclusion of children with disabilities

Aim: New technologies in PE provide children with the opportunity (a) to improve motor learning and self-efficacy, (b) model and stucture new prospective of the educational process (Clapham et al.,2015). The purpose of this study is to evalute and compare (a) the development of motor coordination of primary school\u2019s children in relation to BMI, (b) effects of strategies that utilize interactive video game technology (T0 vs T1), (c) enjoyment and physical selfefficacy between EG and CG. Methods: The study has been conducted in a primary school of Puglia, Italy. The sample includes 65 children, separated into two groups in relation to sex and BMI: EG (M: 22, age,10.09 \ub1 0.30; F:19, age 10.10 \ub1 0.31) and CG (M: 12, age, 10 \ub1 0.42; F: 12, age 10 \ub1 0.0). The experimental program consists of 10 lessons, using specialised interactive video game technology to point out unusual motor responses. For the CG has been used teaching styles of production. The following tests have been proposed before and after the intervention: MOBAK 5 (Hermann and Seelig 2016), PSP_C (physical self-efficacy) and PACES (enjoyment). Results: Besides the descriptive statistics (M \ub1 DS), T-test was used in order to highlights significative differences between T0-T1, indipendently from sex differences. The significance value was set at p\0.05. Data analysis revealed significative differences between EG for boys and girls about (a) Control Object and Self-Movement (p\0.05); (b) and physical self efficacy scale (p\0.05). Conclusions: The use of modern technologies and different teaching styles in PE promote motor learning and self-efficacy in children. The trail of new and different instruments are needed to enhance educational environments and develop intrinsic motivation to motor activities. References 1. Clapham, E.D. et al. (2015).

A Simplified Thermal Model to Control the Energy Fluxes and to Improve the Performance of Buildings

Abstract The article describes an accurate and suitable simplified tool aimed at evaluating, controlling and managing heat energy fluxes in buildings. The focus is the development of a Resistance-Capacitance (RC) thermal model able to represent the envelope thermal inertia on an hourly time basis. The single RC module simulates the thermal response of a single opaque or transparent element of the envelope. Each module consists of 3 Resistances and 2 Capacitances and is connected to the other modules by thermal nodes and coupled to an air internal temperature node in order to obtain a realistic exemplification of the specific boundary conditions and gains distribution in the conditioned space. The differential balance equations in each node have been solved with an explicit numerical method using Modelica simulation tool. A monitoring campaign was carried out on an outdoor test cell in order to observe the real thermal dynamic behaviour and the real hourly energy needs. The results of the model have been compared with the experimental collected data. The results are presented in terms of temperatures and heating power hourly profiles and cumulative daily energy needs. Finally the Bland-Altmann plot has been used to verify the accuracy and the shortcomings of the proposed thermal model

Platelet aggregation is affected by nitrosothiols in patients with chronic hepatitis: in vivo and in vitro studies

AIM: To investigate the relationship among the number of platelets and plasma levels of S-nitrosothiols (S-NO), nitrite, total non-protein SH (NPSH), glutathione (GSH), cysteine (CYS), malondialdehyde (MDA), 4-hydroxininenal (4HNE), tumor necrosis factor-alpha (TNFalpha) and interleukin (IL)-6 in patients with chronic hepatitis C (CH). METHODS: In vitro the aggregation of platelets derived from controls and CH patients was evaluated before and after the addition of adenosine diphosphate (ADP) and collagen, both in basal conditions and after incubation with nitrosoglutathione (GSNO). RESULTS: In vivo, S-NO plasma levels increased significantly in CH patients and they were significantly directly correlated with platelet numbers. Patients with platelet counts 150000/microL. In vitro, the ADP and collagen aggregation time was increased in platelets from patients and not from controls; in addition, platelets from CH patients but not from controls also showed a latency time after exposure to collagen

C5a receptor and thymocyte apoptosis in sepsis

In sepsis, apoptosis occurs in many different organs. The mediators responsible for induction of apoptosis are not clearly known, although there are some suggestions that C5a and the C5a receptor (C5aR) might be directly linked to apoptosis. In the cecal ligation/puncture (CLP) model of sepsis in rats, apoptosis occurs early in a variety of organs, especially in the thymus. We demonstrate that thymocytes from normal rats show specific, saturable, and high affinity binding of 125Iâ labeled recombinant rat C5a. C5a binding to thymocytes was significantly increased 3 h after CLP and also when thymocytes from normal rats were first incubated in vitro with lipopolysaccharide (LPS) or ILâ 6. The expression of C5aR mRNA in thymocytes was markedly increased 3, 6, and 12 h after CLP and increased similarly when normal thymocytes were first exposed to LPS or ILâ 6 in vitro. Thymocytes obtained 2 or 3 h after CLP and exposed in vitro to C5a, but not normal thymocytes, underwent increased apoptosis, as demonstrated by annexinâ V binding, coinciding with increased activation of caspases 3, 6, and 8. These data provide the first direct evidence that in the early onset of sepsis, increased expression of C5aR occurs in thymocytes, which increases their susceptibility to C5aâ induced apoptosis.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/154251/1/fsb2fj020033fje-sup-0001.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/154251/2/fsb2fj020033fje.pd

Pharmacological characterization of a new Ca2+ sensitizer

The benzimidazole molecule was modified to synthesize a Ca(2+) sensitizer devoid of additional effects associated with Ca(2+) overload. Newly synthesized compounds, termed 1, 2, 3, 4, and 5, were evaluated in spontaneously beating and electrically driven atria from reserpine-treated guinea pigs. Compound 3 resulted as the most effective positive inotropic agent, and experiments were performed to study its mechanism of action. In spontaneously beating atria, the inotropic effect of 3 was concentration-dependent (3.0 microM-0.3 mM). Compound 3 was more potent and more active than the structurally related Ca(2+) sensitizers sulmazole and caffeine, but unlike them it did not increase the heart rate. In electrically driven atria, the inotropic activity of 3 was well preserved and it was not inhibited by propranolol, prazosin, ranitidine, pyrilamine, carbachol, adenosine deaminase, or ruthenium red. At high concentrations (0.1-1.0 mM) 3 inhibited phosphodiesterase-III, whereas it did not affect Na(+)/K(+)-ATPase, sarcolemmal Ca(2+)-ATPase, Na(+)/Ca(2+) exchange carrier, or sarcoplasmic reticulum Ca(2+) pump activities of guinea pig heart. In skinned fibers obtained from guinea pig papillary muscle and skeletal soleus muscle, compound 3 (0.1 mM, 1 mM) shifted the pCa/tension relation curve to the left, with no effect on maximal tension and no signs of toxicity. Compound 3 did not influence the basal or raised tone of guinea pig isolated aorta rings, whose cells do not contain the contractile protein troponin. The present results indicate that the inotropic effect of compound 3 seems to be primarily sustained by sensitization of the contractile proteins to Ca(2+)
