Isolation and characterization of 24 polymorphic microsatellite loci for the study of genetic population structure of the sheepshead Archosargus probatocephalus (Actinopterygii, Perciformes, Sparidae)

Background The sheepshead (Archosargus probatocephalus) is found in nearshore waters from Nova Scotia, Canada, to Rio Grande do Sul, Brazil. In the southeastern United States two subspecies are recognized based on a number of meristic characters, primarily counts of melanistic pigment bars. The only previous study based on mtDNA control-region sequence found limited divergence...

The systemic lupus erythematosus travel burden survey: baseline data among a South Carolina cohort

Background Many studies on the impact of systemic lupus erythematosus or lupus have identified patient travel costs as being problematic. We administered a survey that examined the impact of self-rated travel burden on lupus patients. The systemic lupus erythematosus travel burden survey included 41 patients enrolled in the systemic lupus erythematosus database project at the...

CABRA: Cluster and Annotate Blast Results Algorithm

Background Basic local alignment search tool (BLAST) searches are frequently used to look for homologous sequences and to annotate a query protein, but the increasing size of protein databases makes it difficult to review all results from a similarity search. Findings We developed a web tool called Cluster and Annotate Blast Results Algorithm (CABRA), which enables a rapid BLAST...

Arbutin encapsulated micelles improved transdermal delivery and suppression of cellular melanin production

Background Hyperpigmentation is a skin disorder characterized by elevated production of melanin. Current treatment approaches mainly rely on the application of skin lightening chemicals, most of which have safety issues. Efficacy of delivery of the active ingredients to the target organ has also been a challenge. Transdermal based drug delivery platform has been shown to improve...

Aortic aneurysm with complete atrioventricular block and acute coronary syndrome

Background Acute aortic dissection (AAD) is a highly lethal and prevalent cardiovascular emergency. AAD can develop into atrioventricular conductivity disorders caused by coronary artery dissection, with acute myocardial infarction (AMI) being the most frequent clinical sign. In many deceased patients, the diagnosis is not confirmed until autopsy, and 85 % receive the wrong...

Simulated-use validation of a sponge ATP method for determining the adequacy of manual cleaning of endoscope channels

Development and testing of a new system for assessing wheel-running behaviour in rodents

Background Wheel running is one of the most widely studied behaviours in laboratory rodents. As a result, improved approaches for the objective monitoring and gathering of more detailed information is increasingly becoming important for evaluating rodent wheel-running behaviour. Here our aim was to develop a new quantitative wheel-running system that can be used for most typical...

The limits of defaults: why french fries trump apple slices

Background Healthy default food choices have been suggested as a way to encourage better nutrition without restricting choice. Will they work with children and their favorite foods? Methods A group of children, 6–8 years old, were treated to lunch at fast food restaurant on 2 days 2 weeks apart. On both days the children were served chicken nuggets and a drink. On the first day...

Assessing patients’ attitudes to opt-out HIV rapid screening in community dental clinics: a cross-sectional Canadian experience

Background As a public health initiative, provided-initiated HIV screening test in dental settings has long been available in the U.S.; it was only in 2011 that such setting was used in Canada. The objective of this paper was to assess patients’ response to, and attitudes towards, an opt-out rapid HIV screening test in a dental setting in Vancouver, Canada. Methods A cross...

Dengue fever with diffuse cerebral hemorrhages, subdural hematoma and cranial diabetes insipidus

Background Neurological manifestations in dengue fever occur in <1 % of the patients and known to be due to multisystem dysfunction secondary to vascular leakage. Occurrence of wide spread cerebral haemorrhages with subdural hematoma during the leakage phase without profound thrombocytopenia and occurrence of cranial diabetes insipidus are extremely rare and had not been reported...

Subclinical inflammation in relation to insulin resistance in prediabetic subjects with nonalcoholic fatty liver disease

Background Nonalcoholic fatty liver disease (NAFLD) is a metabolic disease commonly associated with obesity, type 2 diabetes, and inflammation-all features of insulin resistant syndrome. However, very limited data are available regarding the association of subclinical inflammation and insulin resistance with NAFLD in a prediabetic state. We, therefore, conducted the study to...

Genotyping-by-sequencing in an orphan plant species Physocarpus opulifolius helps identify the evolutionary origins of the genus Prunus

Background The Rosaceae family encompasses numerous genera exhibiting morphological diversification in fruit types and plant habit as well as a wide variety of chromosome numbers. Comparative genomics between various Rosaceous genera has led to the hypothesis that the ancestral genome of the family contained nine chromosomes, however, the synteny studies performed in the Rosaceae...

Application of a framework for determining number of drugs

Background There are many different methodologies used in the literature for determining the number of drugs used by a patient, and many are incompletely described. This may be attributable to the lack of a framework to help investigators choose and describe their methods and the lack of evidence on the implications of the choice. The purpose of the study was to propose a...

Sleep duration and treatment compliance: a population-based cross-sectional study of hypertensive patients in Bangladesh

Background Treatment with appropriate medication is a key factor to control hypertension and reduce the associated risk of complications. However, compliance with treatment is often sub-optimal, especially in developing countries. Our aim in this cross-sectional study is to investigate whether there is an association between sleep duration and treatment compliance among skilled...

Impact of serotype and sequence type on the preferential aerosolization of Streptococcus suis

Background Streptococcus suis is a swine pathogen that causes pneumonia, septicemia and meningitis. It is also an important zoonotic agent responsible of several outbreaks in China. S. suis strains are classified into 35 serotypes based on the composition of their polysaccharide capsule. S. suis serotype 2 causes the majority of severe infections in pigs and in human, and can be...

Lung function and associations with multiple dimensions of dental health: a prospective observational cross-sectional study

Background Epidemiological data suggest an association between respiratory diseases and periodontal health. However, the link between the overall dental status and single lung function measures, within a practical clinical context, is not well studied. Methods Following a prospective cross-sectional design, consecutive adult patients were evaluated. Next to spirometry...

Cases of human brucellosis in Sweden linked to Middle East and Africa

Background Human brucellosis cases are still reported each year in Sweden despite eradication of the disease in animals. Epidemiological investigation has never been conducted to trace back the source of human infection in the country. The purpose of the study was to identify the source of infection for 16 human brucellosis cases that occurred in Sweden, during the period 2008...

Development and validation of the Japanese version of cognitive flexibility scale

Background Various instruments have been developed to assess cognitive flexibility, which is an important construct in psychology. Among these, the self-report cognitive flexibility scale (CFS) is particularly popular for use with English speakers; however, there is not yet a Japanese version of this scale. This study reports on the development of a Japanese version of the...
