There is a growing body of evidence to suggest that resistance training exercise combined with blood flow restriction (BFR) increases muscle size and strength in humans. Eccentric contraction (ECC) frequently induces severe muscle damage. However, it is not known whether and to what extent muscle damage occurs following ECC + BFR due to the difficulty of conducting definitive invasive studies. ...

Evaluation of The Acute Hormonal Responses To Concentric, Eccentric And Concentric_ Eccentric Muscle Actions in Healthy Young Men Introduction: Resistance exercise is a potent stimulus for acute increase in the concentrations of circulating hormones such as Growth Hormone (GH) and Testosterone. Conventional resistance exercise is performed using sequential concentric (CON) and eccentric (EC...

Liver dynamic contrast enhanced (DCE) MRI pharmacokinetic modelling could be useful in the assessment of diffuse liver disease and focal liver lesions, but is compromised by errors in arterial input function (AIF) sampling. In this study, we apply cardiac output correction to arterial input functions (AIFs) for liver DCE MRI and investigate the effect on dual-input single compartment hepatic pe...

introduction: radioiodine therapy is an effective method for treating thyroid cancer carcinoma, but it has some affects on normal tissues, hence dosimetry of vital organs are important to weigh the risks and benefits of this method. the aim of this study is to measure the absorbed doses of important organs by mcnp (monte carlo n particle) simulation and comparing the results of different method...

BACKGROUND Coronary artery bypass grafting (CABG) with extracorporeal circulation (ECC) is the gold standard for surgical coronary re-vascularisation. Recently, minimised extracorporeal circulation system (MECC) has been postulated a safe and advantageous alternative for multi-vessel CABG. METHOD Between January 2004 and December 2007, 244 high-risk patients (logistic EuroScore (ES)>10%) unde...

AIM We investigated architectural, functional and molecular responses of human skeletal muscle to concentric (CON) or eccentric (ECC) resistance training (RT). METHODS Twelve young males performed 10 weeks of concentric (CON) or eccentric (ECC) resistance training (RT) (n = 6 CON, 6 ECC). An additional 14 males were recruited to evaluate acute muscle fascicle behaviour and molecular signallin...

Introduction: The CT machine utilizes a bowtie filter to shape the X-ray beam and remove lower energy photons. Configuration of this bowtie filter is complex and its geometry is often not available in detail. It causes the CT dose index (CTDI) be with the different values in measurement versus Monte Carlo simulation studies and other analytical calculations. It is important esp...

PURPOSE To design a Head and Neck (H&N) anthropomorphic QA phantom that the Imaging and Radiation Oncology Core Houston (IROC-H) can use to verify the quality of intensity modulated proton therapy (IMPT) H&N treatments for institutions participating in NCI clinical trials. METHODS The phantom was created to serve as a remote auditing tool for IROC-H to evaluate an institution's IMPT planning ...

background:   to find out if there is an association between levels of salivary mutans streptococci (ms)   materials and methods:   t -test were used to find differences between groups. p   results:   p   p   p   conclusion:   present study showed a strong association between maternal and child salivary   ms levels indicating that mother’s ms count could be an important risk indicator for ecc d...
