Filter by:The aim of the present research is to define the effects of short manual treatment of soft tissues compared to mechanisms explaining in Delayed Onset Muscle Soreness (DOMS) among sport climbers and to address the mechanisms of peripheral and central sensitization involved in DOMS phenomena.
DETERMINE trial is a prospective multicenter multinational cohort study. This study will be carried out to predict the risk of bloodstream infections (BSIs) or other types of invasive infection with carbapenem resistant K.pneumoniae in patients being colonized by CRKp. The results of DETERMINE trial would be quite important to prevent unnecessary coverage of carbapenem resistant Klebsiella pneumoniae in empirical treatment of colonized patients. In this study, both risk score model and decision tree algorithm will be constructed and compared with each other in terms of sensitivity, specificity, positive predictive value and negative predictive value.
Cranial USG is simple and easy method to assess preterm infant brain. Some studies showed that brain volumes of preterm infants could be calculated by measurement of 2D distances. Our aim in this study was to compare brain volume obtained by USG and MRI.
The study is a prospective clinical study which investigates the use of new diagnostic methods to localize aggressive lymphoma involving the central nervous system(CNS). By measuring cell-free tumor DNA and metabolomics in cerebrospinal fluid and blood in patients with systemic Diffuse Large B-cell Lymphoma the investigators aim to improve the diagnostic certainty of an impending relapse of lymphoma in CNS.
Shoulder impingement syndrome is the most common shoulder disorder in overhead athletes. It describes a mechanical compression of subacromial bursa and rotator cuff tendons during arm movement, which results in pain and injuries. Most of previous studies focus on investigating motor performance in individuals with shoulder impingement syndrome and found altered scapular kinematics and muscle activation may contribute to the impingement. Recently few studies found changes in the central nervous system, decreases in corticospinal excitability and increases in inhibition in scapular muscles, by using transcranial magnetic stimulation (TMS). Although more studies are still needed to investigate the changes in central nervous system in the individuals with impingement syndrome, the changes in central nervous system are believed to be associated with the deficits of impingement syndrome. However, the exercise protocols for the impingement syndrome are usually designed to restore scapular kinematics and muscle activation, including scapular muscle strengthening exercise and scapular control exercise. To our knowledge, no study has investigated whether these exercise protocols can reverse these changes in the corticospinal system. The objectives of this proposal are to understand neuromuscular and neurophysiological mechanisms of the scapula-focused exercise protocols to improve the effectiveness of treatment. The study aims to investigate the effects of scapular muscle strengthening training and scapular control training on the scapular kinematics, muscle activation and corticospinal system. The study also aims to investigate whether any other cortical mechanisms are also affected by the shoulder impingement syndrome. We will recruit 70 overhead athletes with shoulder impingement syndrome and 22 healthy control athletes. Subjects with shoulder impingement syndrome will randomly receive either scapular muscle strengthening or scapular control training. When performing the exercise, subjects in the scapular control training group will receive electromyography feedback and cues but those in the strengthening training group will not. Immediate effects of these two training protocols on scapular kinematics, muscle activation, and neurophysiological measures will be tested before and after the training. Neurophysiological measures will be tested by TMS, including corticospinal excitability, cortical inhibition, intracortical inhibition, and intracortical facilitation.
To compare responses to acute oral doses of ethanol in healthy young adults who experience mainly stimulant subjective effects from the drug or mainly sedative effects.
To evaluate the relationship of extraversion to both the acute subjective and behavioral effects of alcohol, and the neural reactivity to the anticipation of reward.
This study is a clinical trial to determine the safety of inoculating G207 (an experimental virus therapy) into a recurrent or refractory cerebellar brain tumor. The safety of combining G207 with a single low dose of radiation, designed to enhance virus replication, tumor cell killing, and an anti-tumor immune response, will also be tested.

Xanamem™ is being developed as a potential drug for Alzheimer's disease. This study drug has been designed to change the cortisol levels in the brain. Cortisol is a naturally occurring hormone in the body. It is believed that reducing the level of cortisol will be a benefit in the treatment of Alzheimer's disease. The XanaHES study is testing the safety and tolerability of Xanamem. It is planned to enrol approximately 84 participants, male and female aged from 50 to 75 who are in good health, in the study at 1 centre in Australia. The XanaHES Phase I study is a single-blind study. Subjects will be randomised to receive either 20mg once daily Xanamem or Placebo in cohort 1. Once all subjects have completed the study treatment of 12 weeks, a dose escalation committee will decide if a new cohort, cohort 2, with 30mg once daily vs placebo is started.
Brain metastases (BM) are the most prevalent tumors of the central nervous system (CNS), with a ratio of 10: 1 in relation to primary tumors. In prospective studies, whole-brain radiotherapy (WBRT) reduced the risk of local recurrence after resection of brain metastases from 46-59% to 10-28%. Furthermore, WBRT reduces the incidence of new metastases and death from disease, but no apparent improvement in overall survival (OS). Due to the potential neurocognitive effects associated with WBRT compared to isolated focal approach, several authors have suggested delaying WBRT and perform focal adjuvant RT after resection of isolated BM. In this context, intraoperative radiotherapy (IORT) in the cavity after resection of BM may be an appealing option. The primary objectives of this study are to evaluate local control (LC) and the control of brain disease (LC associated with the absence of new distant BM) after IORT for one completely resected supratentorial BM in the presence of up to 10 lesions suggestive of BM.
