Blastomycosis is a fungal infection caused by inhaling Blastomyces dermatitidis spores. If it involves only the lungs, it is called pulmonary blastomycosis. Only about half of people with the disease have symptoms, which can include fever, cough, night sweats, muscle pains, weight loss, chest pain, and feeling tired.

Microscopic photograph of a professionally prepared slide demonstrating vulvar malignant melanoma. Melanomas of the vulva and vagina are rare, accounting for no more that 2% of melanomas among women. Melanoma of the vulva behaves like melanoma in any other location and may affect a much younger population.
The glucagon like peptide-1 receptor (GLPr) is a G proteincoupled receptor (GPCR) that mediates the action of GLP-1, a peptide hormone. The activated receptor has a strong effect on the management of type 2 diabetes mellitus and obesity, including glucose homeostasis and regulation of gastric motility and food intake.
