Background:The A3243G mutation in the tRNALeu gene (UUR), is one of the most common pathogenic mitochondrial DNA (mtDNA) mutations in France, and is associated with highly variable and heterogeneous disease phenotypes. To define the relationships between the A3243G mutation and
Background:A central question in evolutionary biology is how cryptic species maintain species cohesiveness in an area of sympatry. The coexistence of sympatrically living cryptic species requires the evolution of species-specific signalling and recognition systems. In nocturnal, dispersed living species, specific
Background:Botulism is a rare disease caused by intoxication leading to muscle weakness and rapidly progressive dysphagia. With adequate therapy signs of recovery can be observed within several days. In the last few years, brain imaging studies carried out in healthy
Background:The present study aimed at assessing the psychometric properties of psychosocial determinants of physical activity-related measures in Iranian adolescent girls.Methods:Several measures of psychosocial determinants of physical activity were translated from English into Persian using the back-translation technique. These translated measures
Background:In rural Gambia, birth season predicts infection-related adult mortality, providing evidence that seasonal factors in early life may programme immune development. This study tested whether lymphocyte subpopulations assessed by automated full blood count and flow cytometry in cord blood and
Background:The principles of protein folding and evolution pose problems of very high inherent complexity. Often these problems are tackled using simplified protein models,e.g. lattice proteins.The CPSP-tools package provides programs to solve exactly and completelythe problems typical of studies using 3D
In various settings, drug market policing strategies have been found to have unintended negative effects on health service use among injection drug users (IDU). This has prompted calls for more effective coordination of policing and public health efforts. In Vancouver,
Background:Music is ever present in our daily lives, establishing a link between humans and the arts through the senses and pleasure. Sound technicians are the link between musicians and audiences or consumers. Recently, general concern has arisen regarding occurrences of
Background:As computational performance steadily increases, so does interest in extending one-particle-per-molecule models to larger physiological problems. Such models however require elementary rate constants to calculate time-dependent rate coefficients under physiological conditions. Unfortunately, even when in vivo kinetic data is available,
Background:Although orthotopic heart transplantation has been an effective treatment for end-stage heart failure, the incidence of allograft failure has increased, necessitating treatment options. Cardiac retransplantation remains the only viable long-term solution for end-stage cardiac allograft failure. Given the limited number
Background:Particulate systems are well known to be able to deliver drugs with high efficiency and fewer adverse side effects, possibly by endocytosis of the drug carriers. On the other hand, cationic compounds and assemblies exhibit a general antimicrobial action. In
Background:Cancer risks of migrants might differ from risks of the indigenous population due to differences in socioeconomic status, life style, or genetic factors. The aim of this study was to investigate cancer patterns among children of Turkish descent in Germany.
Background:Patients with psychosocial problems may benefit from a variety of community, educational, recreational and voluntary sector resources, but GPs often under-refer to these through lack of knowledge and time. This study evaluated the acceptability and effectiveness of graduate primary care
The use of cardiopulmonary bypass as an adjunct to airway surgery for non-malignant diseases in adults is not well established in the UK. We are reporting two cases which demonstrate the additional benefits of using cardiopulmonary bypass during difficult bronchoscopy
IntroductionHepatic and splenic hemangiomas are common benign tumors that mainly affect female patients. Giant splenic hemangiomas are extremely rare, especially when correlated with multiple hepatic hemangiomas. Pathogenetic mechanisms between hemangiomas and oral contraceptives, as well as therapeutic approaches, are analyzed
Primm said, "It's not on the radar screen. There are not enough voices being raised." Primm said the spread of HIV among black women in particular has not received the same media attention as other groups. He said HIV/AIDS cases
The report, as well as testimony from hospital officials, is part of a two-day hearing on hospital preparedness (Miller, Washington Times , 5/6). HHS Secretary Mike Leavitt and Department of Homeland Security Secretary Michael Chertoff will testify on the issue
The program, called the Community Action Against the HIV/AIDS Scourge, will be launched in 27 districts in the country. With funding from USAID , IHAA will train people living with the disease to become network support agents to improve the
We are proud to honor 30 psychiatrists from 21 states, who are stars within the nation's mental healthcare system," said NAMI national executive director Michael J. Fitzpatrick. "They each have shown an exemplary commitment to treatment and recovery for people
