the neuregulin is a member of the epidermal growth factors (egf) family of receptor kinases, was originally identified as the product of the transforming gene derived from chemically induced rat neuroblastoms. a variety of different protein isoforms are produced from single neuregulin gene. four distinct vertebrate gene encode neuregulin, prosaically named nrg1, nrg2, nrg3, and nrg4. most of bi...

The iodinated radiopaques are widely used in radiologicals procedures for their higher quality and for better pathological diagnosis. Since they are numerous and can lead to cellular toxicity and/or genotoxicity, this study was carried out to investigate the efficacy of two routine compounds, that is, urographin 76% and telbrix 38. For this purpose, the metaphasic chromosomes of 30 patients un...

The prompt use of computerized tomography has significantly enhanced the early localization of traumatic posterior fossa hematoma of the brain. Consequently, timely surgical intervention has been possible before irreversible damage has set in. The result is an overall improvement in the survival of patients with this condition. The clinical presentations of 2 children who developed traumatic po...

1 KEY POINTS • Exercise and nutrition can influence brain development in youth. • Exercise and nutrition can slow down and reverse cognitive decline in the elderly. • Exercise and nutrition influences brain health through several mechanisms that create new neurons (neurogenesis). • Fatigue during exercise can reside in the brain. • Nutritional interventions may influence the occurrence of “cent...

Introduction: Computerized programs for brain empowerment with regular, intensive, and continuous cognitive exercises improve functions such as attention in deficit hyperactivity disorder. This review study aimed to identify effective computerized improving children adolescents disorder (ADHD). Method: descriptive narrative was done 2018 through library searching keywords including "attention d...

Cardiopulmonary exercise testing is useful in diagnosing the cause of exercise intolerance, in evaluating disability, and in defining the response to therapy. This testing modality is firmly founded on physiological principles. An efficient interaction of the body's systems is required to transport oxygen to the exercising muscles; failure of any system will yield characteristic changes in the ...

The purpose of this study was to develop a computerized exercise expert system (CEES) that creates tailored exercise plans for older adults. A panel of experts was selected in the areas of medicine, exercise physiology, health promotion, exercise psychology, and gerontology. The experts communicated with the principal investigator and the project members by mail, email, telephone, and expert me...

Neurorehabilitation is increasingly taking account of scientific findings. Research areas directing stroke rehabilitation are neurophysiology; adaptability to use and activity; biomechanics; skill learning; and exercise science (task, context specificity). Understanding impairments and adaptations enables a reappraisal of interventions-for example, changes in motor control resulting from impair...

Phenylketonuria is the most common inborn error of metabolism. Adult patients often discontinue dietary treatment and can subsequently develop serious brain dysfunction. Some of them, however, do not present any symptoms, despite long-term exposition to high blood phenylalanine concentration. As the extent of brain toxicity of hyperphenylalaninemia is not clear in adults, new diagnostic methods...
