Objectives: The Matrix Model is used for MA dependence in methadone services in Iran, the most populated Persian Gulf country. However, there are no studies of the efficacy of the Matrix Model for MA dependence while in treatment. The present study reports on the efficacy of sixteen weeks of the Matrix Model for MA abstinence and general health.  Methods: There were MA-dependent male (n=3...

Two studies were carried out to test the hypothesis that the fall and recovery of nasal resistance after exercise in asthmatic and non-asthmatic subjects are related to the development of bronchoconstriction after exercise. In study 1 nasal resistance (posterior rhinomanometry) and specific airway resistance (sRaw) were measured before challenge and one, five, 10 and 30 minutes after four minut...

INTRODUCTION Exhaustive and/or unaccustomed exercise, mainly involving eccentric muscle actions, induces temporary muscle damage, evidenced by delayed onset muscle soreness (DOMS) and decreased muscle function. Different strategies to recover from its signs and symptoms have been studied and, as a result, a significant number of articles on this issue have been published. OBJECTIVE To assess ...

PURPOSE To evaluate the dynamic characteristics of T2* -weighted signal change in exercising skeletal muscle of healthy subjects and peripheral artery disease (PAD) patients under a low-intensity exercise paradigm. MATERIALS AND METHODS Nine PAD patients and nine age- and sex-matched healthy volunteers underwent a low-intensity exercise paradigm while magnetic resonance imaging (MRI) (3.0T) w...

To determine the antihypertensive efficacy of aerobic exercise training in mild essential hypertension, a prospective randomized controlled trial was conducted comparing an aerobic exercise regimen to a placebo exercise regimen, with a crossover replication of the aerobic regimen in the placebo exercise group. The study took place in an outpatient research clinic in a university-affiliated Vete...

We investigated the influence of aging on the group III/IV muscle afferents in the exercise pressor reflex-mediated cardiovascular response to rhythmic exercise. Nine old (OLD; 68 ± 2 yr) and nine young (YNG; 24 ± 2 yr) males performed single-leg knee extensor exercise (15 W, 30 W, 80% max) under control conditions and with lumbar intrathecal fentanyl impairing feedback from group III/IV leg mu...

Particulate matter 2.5 (PM2.5) is an environmental pollutant linked with the risk of cardiovascular disease. Aerobic exercise performed in polluted environments may have fewer benefits because increased PM2.5 inhalation during exercise. However, vascular responses to aerobic high (HPM2.5) conditions remain unknown. This study aimed examine acute flow-mediated dilation (FMD) response moderate-in...

We analyze student affect data in order to locate bottlenecks in an introductory programming course. By tracking students’ affective states and behaviors over five laboratory sessions distributed over nine weeks, we find that students exhibit a significantly greater amount of confusion when expected to implement object-oriented constructs such as constructors and object interaction. When asked ...

Lecerof, H. (1974). Thorax, 29, 673-677. Central haemodynamics during oxygen breathing in angina pectoris. The haemodynamic effects of breathing 100% oxygen have been studied by right heart catheterization at rest and during bicycle exercise in nine male patients with coronary heart disease. Oxygen breathing produced no significant haemodynamic benefit during angina pectoris induced by physical...

Isokinetic dynamometers may provide a useful means of measuring muscle stiffness resulting from eccentric exercise because they can measure torque from computer-controlled passive movements of joints (passive resistive torque; PRT). In this study, a Biodex measured increased ankle PRT (52%; p <.001) following heel drop exercise in nine young women. Therefore, isokinetic dynamometers can provide...
