Electromyographic validation of the trapezius and serratus anterior muscles in rowing exercises with closed grip.

Because the lack of specialized textbooks, the select of basic exercises for physical conditioning programmes is based on empirical knowledge. This fact led the authors to propose the study on electromyographic activity of the trapezius (upper portion) (TS) and the serratus anterior (lower portion) (SI) muscles in rowing exercises with closed grip in three different modalities. The tests were carried out with 24 male volunteers, 18 to 25 years old, by using a two-channel TECA TE 4 electromyograph and Hewlett Packard surface electrodes.

Electromyographic validation of the trapezius and serratus anterior muscles in rowing exercises with middle grip.

Because the lack of textbooks based on electromyographic studies in the area of exercises for physical conditioning, the authors proposed to study the trapezius (upper portion) (TS) and the serratus anterior (lower portion) (SI) muscles during the execution of four different modalities of rowing exercises with middle grip in 24 male volunteers, 18 to 25 years old. For the recordings, it was used a two-channel TECA TE 4 electromyograph and Hewlett Packard surface electrodes. For the movements, a supine bench and a 120 cm-long bar made of low weight wood were used.

Crash protection for children in ambulances.

The objectives of the study were to determine the most effective and reliable means of restraining children on an ambulance cot and to develop recommended field procedures for emergency medical service providers. A series of crash tests at 48 km/h were conducted using convertible child restraints, car beds, and harness systems tested with 3-year, infant, and 6-year size dummies. Belt configuration and backrest position were varied.

The association between risk-taking behavior and the use of safety devices in adolescents.

The purpose of this research study was to measure the association between risk taking behavior in adolescents and their use of safety devices. The study focused on three safety devices: seat belts, motorcycle helmets, and bicycle helmets. This is a secondary data analysis using data from the Youth Risk Behavior Survey conducted by the Centers for Disease Control and Prevention.

Implementing a comprehensive child restraint program in a pediatric hospital: an effective model.

Motor vehicle crashes remain a leading cause of death and injury to young children. Appropriate child safety seats and child safety restraints can provide life-saving protection to children riding in motor vehicles. Many children, however, travel unrestrained or improperly restrained.

The incidence of thyroid abnormalities in adults irradiated for lymphoma.

The aim of the study was to investigate the incidence of thyroid abnormalities in neck irradiated lymphoma patients. Of the 298 patients who had irradiation to the neck for lymphoma between 1966-1988, 174 were found to be alive and free of disease. These patients were invited to participate in the study.

Electromyographic validation of the trapezius and serratus anterior muscles in the rowing and frontal-lateral cross, dumbbells exercises.

The trapezius and serratus anterior muscles were studied in four modalities of rowing exercises executed with two grips, middle and closed, in comparison with the four different modalities of frontal-lateral cross, dumbbells exercise. It was used 24 male volunteers, 18 to 25 years old using a 2-channel TECA TE 4 electromyograph and Hewlett Packard surface electrodes. The results showed that TS acted in a higher significant way in all the modalities of rowing than in the supine lateral raise, inclined supine lateral raise and reverse supine lateral raise, dumbbells exercices, and demonstrated no standing frontal-lateral cross, dumbbells.

Feline immunodeficiency virus infection is characterized by B7+CTLA4+ T cell apoptosis.

The B7.1 and B7.2 costimulatory molecules on antigen-presenting cells provide second signals for regulating T cell immune responses via CD28 and cytotoxic T lymphocyte antigen 4 (CTLA4) on T cells.

Electromyographic validation of the trapezius and serratus anterior muscles in frontal-lateral cross, dumbbells exercises.

Based on the lack of electromyographic researches on sport and programmes of physical conditioning, we can say that it is necessary to reexamine some exercises routinely used in the programmes of physical conditioning. Thus, the trapezius and serratus anterior muscles were studied electromyographically so that we could evaluate the validity in some ways of execution of the frontal-lateral cross, dumbbells exercises for the development of these muscles. We analyzed 24 male volunteers, 18 to 25 years old, using a 2-channel TECA TE 4 electromyograph and Hewlett Packard surface electrodes.

Polymorphic expression in the CD8alpha chain surface receptor of African lions (Panthera leo).

Free-ranging African lion (Panthera leo) peripheral blood mononuclear cells (PBMC) were examined using flow cytometry and antibodies developed for use in the domestic cat to determine if phenotypic changes occurred in lion lymphocytes as a result of feline immunodeficiency virus (FIV) infection. The percentage of CD8 cells from lion peripheral blood was considerably lower than in the domestic cat. Lions with elevated levels of CD8+ cells were typically infected with FIV, similar to observations in the domestic cat.

The Connecticut Cardiovascular Consortium: a unique, state-wide research collaboration to advance clinical outcomes in patients with heart disease.

The establishment of "best clinical practices" founded upon evidence-based medicine has become an increasingly important priority. Frequently, management guidelines are derived from published research data and disseminated among practitioners to help optimize patient care. The ultimate clinical impact of these guidelines in the "real world," however, is often clouded by an incomplete assessment of patient outcomes throughout the continuum of health-care delivery models.

Electromyographic validation of the trapezius and serratus anterior muscles in military press exercises with middle grip.

Electromyographic activity of the trapezius muscle and serratus anterior muscle was analysed in 24 male volunteers using a 2-channel TECA TE 4 electromyograp, during the execution of four different modalities of military press exercises with middle grip. The trapezius acted preferentially in the modalities standing press behind neck; and sitting forward and press behind neck, while SI did not show any significative difference among the modalities. The high levels of action potentials with which TS and SI acted justify the inclusion of these exercises in physical programmes.

Components of a proper hospital discharge for elders.

Significance: Effective discharge planning is a vital link in continuity of care for elders. Previous studies identify problems with planning for elders' discharge from the hospital and problems elders encounter managing care post-discharge. However, little attention has been given to identifying effective discharge planning processes.

Electromyographic validation of the trapezius and serratus anterior muscles in military press exercises with open and middle grip.

Electromyographic activity of the trapezius muscle and serratus anterior muscle was analysed in 4 different modalities of military press exercises, each of them with 2 grips: open and middle. It was analyzed 24 male volunteers using a 2-channel TECA TE 4 electromyograph and Hewlett Packard surface electrodes. The TS and SI muscles acted with high and very high activity in all the modalities of military press exercises.

Interventions for women as family caregivers.

Family caregivers are the mainstay of long-term care, as they enable chronically ill elders and children to remain at home. The majority of family caregivers are women and historically their caregiving role has been viewed as an extension of their roles as wife and mother. Although numerous studies report the stresses associated with family caregiving and are predictors of burden, less attention has been given to interventions for family caregivers.

Electromyographic validation of the trapezius and serratus anterior muscles in military press exercises with open grip.

It was studied the trapezius muscle and serratus anterior muscle in 24 male volunteers using a 2-channel TECA TE 4 electromyograph and Hewlett Packard surface electrodes, during the execution of four different modalities of military press exercises with open grip. The results showed that TS acted significantly in the modalities standing and sitting press behind neck, while SI acted in all the modalities, i.e.

Lawn mower-related injuries to children.

Lawn mower-related injuries to children are relatively common and can result in severe injury or death. Many amputations during childhood are caused by power mowers. Pediatricians have an important role as advocates and educators to promote the prevention of these injuries.

Spontaneous inflammatory disease in HLA-B27 transgenic mice does not require transporter of antigenic peptides.

HLA-B27 is strongly linked with a group of human diseases called spondyloarthropathies. Even though HLA-B27 as an MHC class I molecule would be expected to present endogenously processed peptides such as cytosolic or viral proteins, many of the B27-linked diseases begin after an infection with an enterobacteria, an exogenous antigen. In our previous studies, we have described development of spontaneous inflammatory disease in HLA-B27 transgenic mice expressing beta(2)m free heavy chains on the cell surface.

Discharge planning for older people: a review of current research.

The NHS and Community Care Act 1990 emphasized the importance of discharge planning for elders and recognized the role of community health nurses in promoting continuity of care. Given the emphasis on discharge planning for vulnerable populations at policy level, it is timely for nurses to examine the research literature for evidence that may guide practice. This article reviews the key findings of research related specifically to discharge planning for older people and suggests areas in which additional research is needed.

Transporting children with orthopaedic conditions and surgeries.

While motor vehicle crashes remain one of the leading causes of death and injury to children, proper and consistent use of child safety seats and safety belts can greatly improve children's chances of survival in motor vehicle crashes. Children with orthopaedic conditions and children after orthopaedic surgery, however, may be restricted to specialized child restraint options that are capable of providing proper fit and safe travel for a period of time after the procedure. To assure proper selection and avoid secondary injury, parents and health care professionals need to be aware of best practices for transporting children postoperatively and of restraint options that exist for children with orthopaedic conditions.

Measuring continuity of elders' posthospital care.

Continuity of care is a critical component of quality patient care, yet the paucity of reliable and valid measures of continuity of care make it difficult to ascertain the extent to which continuity has been achieved. The purpose of this article is to describe the development of an instrument to measure continuity of care that incorporates the perspectives of elders hospitalized for a chronic illness and their family caregivers. The instrument was used, and its reliability and validity examined, in a series of studies related to elders' posthospital transition.
