DNA barcoding Brooklyn (New York): A first assessment of biodiversity in Marine Park by citizen scientists.

DNA barcoding is both an important research and science education tool. The technique allows for quick and accurate species identification using only minimal amounts of tissue samples taken from any organism at any developmental phase. DNA barcoding has many practical applications including furthering the study of taxonomy and monitoring biodiversity.

Accessibility and usability of parks and playgrounds.

Background: Public parks and playgrounds are an environment for leisure activity, which all generations can enjoy at low or no financial cost. Evaluating the accessibility and usability of parks and playgrounds is crucial because their design, environment (natural and built) and safety could restrict participation of persons with disabilities.

Objective: To evaluate the accessibility and usability of 21 public parks and playgrounds in three metropolitan cities of New Zealand.

Erythrokeratoderma variabilis successfully treated with topical tazarotene.

Erythrokeratoderma variabilis, also known as Mendes da Costa syndrome, is a genodermatosis belonging to the group of diseases known as the erythrokeratodermias. Erythrokeratoderma variabilis is characterized by two distinctive manifestations: well-demarcated, variable, transient, figurate patches of erythema, and localized or generalized hyperkeratotic plaques. Treatments include topical retinoic acid, salicylic acid, and alpha-hydroxy acid in petrolatum, but all have been reported to have limited, variable success rates.

Exact analysis of dose response for multiple correlated binary outcomes.

The neurotoxicity of a substance is often tested using animal bioassays. In the functional observational battery, animals are exposed to a test agent and multiple outcomes are recorded to assess toxicity, using approximately 40 animals measured on up to 30 different items. This design gives rise to a challenging statistical problem: a large number of outcomes for a small sample of subjects.

Regression of cutaneous intravascular lymphoma with rituximab.

Intravascular lymphoma, also known as malignant angioendotheliomatosis or angiotropic lymphoma, is a rare non-Hodgkin lymphoma that is usually fatal. It often presents with cutaneous and/or nervous system involvement, but the disease can involve any organ system. Clinical symptoms result from the occlusion of small vessels by tumor cells and fibrin.

Mycobacterium haemophilum infections in heart transplant recipients: case report and review of the literature.

Non-tuberculous mycobacteria are becoming increasingly important pathogens among transplant recipients. We report a case of disseminated Mycobacterium haemophilum infection in a heart transplant recipient, manifesting as cellulitis, subcutaneous nodules, septic arthritis, and pneumonitis. Our case illustrates diverse challenges in the identification and treatment of this pathogen, such as its unique culture requirements and variable antimicrobial susceptibilities.
