BACKGROUND Elevated heart rate represents an independent risk factor for cardiovascular outcome in patients with heart disease. In the sinoatrial node, rate increase is mediated by β(1) adrenoceptor mediated activation of the Gα(s) pathway. We hypothesized that genetic inactivation of the stimulatory Gα(s) protein in the sinoatrial node would provide sinus rate control and would prevent inappro...

alzheimer's disease (ad), a common and debilitating neurodegenerative disorder, affect more than 65 million individuals throughout the world. this disability plays a crucial role in daily activities such as driving. several studies have investigated the relationship between cognitive functions and driving safety. the current study revises the literature on the relation between road safety ...

abstract alzheimer’s disease (ad) is the most common cause of dementia in elderly people. the prevalence of alzheimer diseases is increasing in the world due to population aging. metabolic disease such as diabetes and obesity play important role in alzheimer disease. hyperglycemia can play important role in brain damage. it causes cognitive impairments, functional and structural alterations in ...

Objective(s): Epidemiological and biochemical studies conducted over the past two decades have established a strong link between type 2 diabetes mellitus (T2DM) and Alzheimer’s disease (AD). However, the exact mechanisms through which aberrations in insulin signaling associated with T2DM contribute to cognitive decline are not yet known. Materials and Methods: In an effort to explore possible m...

OBJECTIVE The objective of the current study was to detect Staphylococcus aureus colonization and the presence of superantigen in atopic dermatitis (AD) in Egyptian patients, and to determine its effect on disease severity and serum interleukin (IL)-4 levels. METHODS Swabs were taken from the skin of 30 patients with AD. S. aureus isolates were screened for the presence of genes of exotoxins ...

One of the most serious neurodegenerative disorders is Alzheimer disease (AD). As the population is aging and due to the fact that AD is more common in aged people, more attention must be paid to this disease. One of the main characteristics of AD is dementia which starts with loss of short term memory, then progresses and causes various brain dysfunctions such as loss of long term memory. Inte...

conclusions both task-related and resting fmri techniques have the potential to detect early brain dysfunction related to ad. however, the use of fmri in ad populations thus far has been limited to a relatively small number of research groups. results bold fmri is considered to reflect the joined synaptic activity of neurons through mri signal changes because of alterations in blood flow, blood...

people with alzheimer disease (ad) have decreases in brain cell function that may increase their risks as drivers. the changes in brain cells affect memory (at first, short-term memory and then much later, long-term memory) and other thinking functions. in addition, people with early ad, though often very functional in many areas of life, may not be as competent behind the wheel of a car as tho...
