Cases of mimicry provide many of the nature's most convincing examples of natural selection. Here we report evidence for a case of predator mimicry in which metalmark moths in the genus Brenthia mimic jumping spiders, one of their predators. In controlled trials, Brenthia had higher survival rates than other similarly ...

Glial cytoarchitecture in human cerebral cortex is constituted by two overlapping layouts: the (general mammalian) "glial syncytium" and the (primate-specific) "interlaminar glial palisade" (IGP) composed by astroglial cells, with long, radial processes that traverse several supragranular layers. In this study, the emergence and early organization of the IGP was analyzed ...

The interest in the relationship between benzene exposure and non-Hodgkin lymphoma (NHL) appears to have been generated from a 1979 publication, which reported an increased risk of NHL among persons potentially exposed to benzene and/or coal tar fractions. More recently (1997), an increased risk of NHL was reported among 74,828 ...

To avoid the possible confounding effect of population stratification, we employed a discordant sibling study design and a liberalization of the sibling transmission disequilibrium test to confirm the association of the S18Y variant of the ubiquitin carboxi-terminal hydrolase L1 (UCHL1) gene with Parkinson's disease (PD). The study included 497 case-control ...

Massive presacral bleeding arising during gynaecological surgery can be sudden, rapid and life-threatening. Further, its control and management can be challenging, since standard measures are frequently ineffective. The use of thumbtacks to control severe presacral venous haemorrhage was first reported in 1985. Despite this, it does not appear to be ...

Glossopharyngeal neuralgia (GPN) is a rare condition in which patients present with intractable deep throat pain. Similar to trigeminal neuralgia (TN), treatment with microvascular decompression (MVD) has been successful in both. Because gamma knife surgery (GKS) has also been shown to be effective in treating TN, it seemed reasonable to ...

BACKGROUND: Chronic infections with the nematode worm Strongyloides stercoralis can occur in former WWII Far East prisoners of war (FEPOWs). The condition may be asymptomatic, but frequently causes a characteristic urticarial 'larva currens' rash. Under conditions of immunosuppression (particularly systemic corticosteroid treatment) potentially fatal dissemination of larvae ('hyperinfection') may occur. ...
