Whole-Body Vibration Training Increases Stem/Progenitor Cell Circulation Levels and May Attenuate Inflammation.

Introduction: Whole-body vibration training (WBVT) may benefit individuals with difficulty participating in physical exercise. The objective was to explore the effects of WBVT on circulating stem/progenitor cell (CPC) and cytokine levels.

Methods: Healthy male subjects each performed three activities randomly on separate days: (1) standing platform vibration, (2) repetitive leg squat exercise; and (3) in combination.

Racial differences in sensitivity of blood pressure to aldosterone.

Blacks in comparison with whites are at risk for a more serious form of hypertension with high rates of complications. Greater sodium retention is thought to underlie the blood pressure (BP)-determining physiology of blacks, but specific mechanisms have not been identified. In a prospective observational study of BP, 226 black children and 314 white children (mean age, 10.

Limbic responses to reward cues correlate with antisocial trait density in heavy drinkers.

Antisocial traits are common among alcoholics- particularly in certain subtypes. Although people with antisocial tendencies show atypical brain activation in some emotion and reward paradigms, how the brain reward systems of heavy drinkers (HD) are influenced by antisocial traits remains unclear. We used subjects' preferred alcohol drink odors (AO), appetitive (ApCO) and non-appetitive (NApO) control odors in functional magnetic resonance imaging (fMRI) to determine if reward system responses varied as a function of antisocial trait density (ASD).

Trochanteric excision following persistent nonunion of the greater trochanter.

Trochanteric nonunion associated with total hip arthroplasty (THA) may result from 1 of 3 situations: 1) isolated fracture of the greater trochanter; 2) complication of trochanteric osteotomy; or 3) fracture secondary to cystic formation or osteolysis from wear debris post-THA. Isolated fracture of the greater trochanter can occur during primary or revision THA or as a result of trauma in the post-THA patient. It is estimated that approximately 5% of intraoperative femoral fractures involve just the greater trochanter.

Use of antidementia agents in vascular dementia: beyond Alzheimer disease.

Vascular dementia (VaD) is the second leading cause of dementia and is often underdiagnosed. Stroke is the leading cause of VaD, although it may also develop secondary to a variety of other cerebrovascular or cardiovascular conditions. Currently, no drugs are approved for the treatment of VaD.

Development and implementation of nonpharmacologic protocols for the management of patients with Alzheimer's disease and their families in a multiracial primary care setting.

Purpose: Most patients and families with dementia are cared for in primary care clinics. These clinics are seldom designed to provide the necessary comprehensive care. The purpose of this article is to describe nonpharmacologic protocols for the management of patients with Alzheimer's disease and their families that are administered as part of a multifaceted care-management intervention program in a multiracial primary care clinic.

Multiple sclerosis: low-frequency temporal blood oxygen level-dependent fluctuations indicate reduced functional connectivity initial results.

Purpose: To study the correlation of low-frequency blood oxygenation level-dependent (BOLD) fluctuations on magnetic resonance (MR) images obtained of the left- and right-hemisphere primary motor regions in healthy control subjects and patients with multiple sclerosis (MS).

Materials And Methods: Sixteen healthy volunteers and 20 patients with MS underwent MR imaging with a 1.5-T imager by using a protocol designed to monitor low-frequency BOLD fluctuations.

Response of patients with Alzheimer disease to rivastigmine treatment is predicted by the rate of disease progression.

Background: Evidence suggests that disease severity predicts the response of patients with Alzheimer disease (AD) to cholinesterase inhibitor treatment, raising the question of whether disease progression also predicts response to this treatment.

Objective: To evaluate retrospectively whether rate of disease progression during placebo treatment affects response to subsequent rivastigmine tartrate therapy for patients with mild to moderately severe AD.

Design: A 26-week, open-label extension study following a 26-week, double-blind, randomized, placebo-controlled trial.

Incidence of dementia and Alzheimer disease in 2 communities: Yoruba residing in Ibadan, Nigeria, and African Americans residing in Indianapolis, Indiana.

Context: Alzheimer disease (AD) represents a major and increasing public health problem. If populations were identified with significantly lower or higher incidence rates of AD, the search for risk factors in the genesis of AD could be greatly enhanced.

Objective: To compare incidence rates of dementia and AD in 2 diverse, elderly community-dwelling populations.

Breast cancer in vivo: contrast enhancement with thermoacoustic CT at 434 MHz-feasibility study.

The authors performed thermoacoustic computed tomography (CT) with 434-MHz radio waves in five patients with documented breast cancer. Three of the patients underwent imaging before chemotherapy was initiated and two at the conclusion of their primary chemotherapy. In the former three patients, thermoacoustic CT demonstrated contrast enhancement in the region of the tumor.
