Grambank reveals the importance of genealogical constraints on linguistic diversity and highlights the impact of language loss.

While global patterns of human genetic diversity are increasingly well characterized, the diversity of human languages remains less systematically described. Here, we outline the Grambank database. With over 400,000 data points and 2400 languages, Grambank is the largest comparative grammatical database available.

Role of gallium SPECT-CT in the diagnosis of left ventricular assist device infections.

Infection remains a well-established complication after the placement of left ventricular assist devices (LVADs). Defining the extent of infection is a challenging task as there are few effective imaging modalities and no standardized guidelines regarding imaging in the diagnosis of device-related infections (DRIs). The use of gallium with single photon emission tomography-computed tomography (Ga-SPECT-CT) has not been previously reported in localizing DRIs.

Human papillomavirus 6a lesions of the lower eyelid and genitalia.

A 42-year-old white man presented with a lower eyelid lesion and recurrent condylomata acuminata of his genitalia due to human papillomavirus (HPV) type 6a. Polymerase chain reaction analysis of both lesions was performed. The eyelid lesion was excised and found to be a papilloma caused by HPV6a infection.
