Gonococcal infections are usually localized to the urogenital tract, but may sometimes spread extragenitally and cause cutaneous manifestations, arthritis, tenosynovitis, meningitis, endocarditis, or perihepatitis (Stajano, 1920; Bruusgaard and Thjotta, 1925; Curtis, 1930; Fitz-Hugh, 1934; Williams, 1938; Abu-Nassar, Hill, Fred, and Yow, 1963; Keiser, Ruben, Wolinsky, and Kushner, 1968; Amman, ...

[1] Three alternate China-wide temperature composites covering the last 2000 years were established by combining multiple paleoclimate proxy records obtained from ice cores, tree rings, lake sediments and historical documents. Five periods of temperature variation can be identified: a warm stage in AD 0–240, a cold interval between AD 240 and 800, a return to warm conditions from AD 800–1400, i...

Fluctuations in the length of the day affect developmental processes and behaviors of many organisms. Mammals and birds reproduce in spring in response to lengthening days and insects pupate in autumn when daylength shortens. These phenomena, called photoperiodism, allow detection of seasonal changes and anticipation of environmental conditions such as low temperatures and desiccation. Photoper...

2 Sumner, F. B., and Huestis, R. R., Genetics, Sept., 1921. 3 Almost nothing has been done in the way of hybridizing subspecies. But after all subspecies do not differ in any essential way from species. Whether or not two groups of mammals or birds are regarded as species or subspecies depends upon whether the intergrading forms have been preserved. The extremes are often more widely distinct t...

Neurosurgery as a distinct speciality has been around for 100 years. Some of the earliest women neurosurgeons were European, emerging from 1920′s onwards. Here we detail rise in neurosurgery across Europe with decade by account big events and firsts continent. The themes are seen stories pioneers enormous resilience, camaraderie, trailblazing triumphing system great obstacles challenges. Our jo...

[1] The paucity of high‐resolution paleoclimate records limits our ability to extend instrumental data into a longer time‐frame and to better understand multidecadal climate variations in the Mid‐Atlantic region. Here we present an ∼2 year‐resolution endogenic calcite dO record for the last ∼240 years from a freeze core at White Lake in northern New Jersey. The dO data, consistent with the pale...
