abstract background: fatigue is the most common side effect of chemotherapy in children with acute lymphoblastic leukemia (all).acupressure is one of the most popular non‑pharmacologic methods used to reduce fatigue in other settings. the aim of the study was to evaluate the effect of acupressure on reducing fatigue among children with all compared with a placebo treatment. materials and method...

A procedure to predict the fatigue fracture life of high-heat-load components made of GlidCop has been successfully established. This method is based upon the Manson-Coffin equation with a cumulative linear damage law. This prediction was achieved by consolidating the results of experiments and analyses, and considered the effects of environment and creep. A low-cycle-fatigue test for GlidCop w...

PURPOSE To investigate the process of fatigue in orbicularis oris muscles by analyzing the median frequency of electromyographic signal and the referred fatigue time, according to the breathing mode and the facial pattern. METHODS The participants were 70 children, aged 6 to 12 years, who matched the established criteria. To be classified as 36 nasal-breathing and 34 mouth-breathing children,...

purpose: to investigate the effects of sodium bicarbonate (nahco3) on exhaustive activity and physiological parameters of fatigue in conscripts. materials and methods: thirty conscripts did wingate test in two groups: sodium bicarbonate group (treatment) and placebo (control) group. in both groups, sodium bicarbonate (0.3 g/kg of body mass) or placebo was ingested 60 minutes before the training...

Experimental investigation was conducted on corroded composite push-out specimens to study the behavior of shear studs subjected to fatigue loading. A total of eight standard EC4 push-out specimens were tested. The expected corrosion rate of test specimens ranged from 0 to 50%. The main purpose of these tests was to determine the fatigue life and the reduction effect caused by the corrosion on ...

OBJECTIVES To compare cognitive and emotional outcomes between patients with aneurysmal and perimesencephalic subarachnoid haemorrhage and norm scores. DESIGN First measurement in prospective cohort study. PATIENTS Sixty-seven patients with subarachnoid haemorrhage, were divided into perimesencephalic (n = 8) and aneurysmal (n = 59) subarachnoid haemorrhage groups. METHODS Patients comple...

Fatigue tests are a very time consuming process in engineering, in which also a lot of energy is required. Speeding up fatigue tests and making them less energy consuming, would lead to major profits. The aim of this study is to obtain these profits by the development of a new bending fatigue test. In addition, the objective is to apply this new method to the bending fatigue test of rings from ...

BACKGROUND AND PURPOSE Pain is currently evaluated with "subjective" methods (eg, patient self-report). This study aimed to test whether fatigue indexes are able to accurately discriminate between subjects with and subjects without low back pain. SUBJECTS Sixty subjects separated into 2 groups--a group with low back pain (n=30) and a group without low back pain (n=30)--participated in this st...

Fatigue refers to the decrement of response seen with repeated stimulation and is a prominent attribute of nociceptors. Whether fatigue in nociceptors involves transduction, spike initiation, or conduction mechanisms is unknown. We investigated systematically how electrical, mechanical, and heat conditioning stimuli (eCS, mCS, hCS) affected the subsequent response to a test-heat stimulus applie...

the purpose of this study was to investigate the effect of caffeine ingestion on anaerobic power; fatigue index and blood lactate levels in boys athlete students. among voluntarers 16 subjects were selected and devided into two caffeine and placebo groups in a simple – randomized manner base on fatigue index in the pretest. they were asked to prevent from doing intensified activities 24 hours p...
