Spiders have highly developed mechanosensory systems, some of which provide access to forms of stimulation alien to our own sensations. Studies of hair-shaped air movement detectors (trichobothria) and tactile sensors have uncovered an outstanding refinement of the processes of stimulus uptake and stimulus transformation, which reflect details of both ...

Comparative Biochemistry and Physiology, 1966
Abstract 1. 1. The reported diversity of excretory products of spiders and the small number of species investigated in this regard prompted a reinvestigation of the excreta of these arthropods. 2. 2. Guanine was the only purine detected in the chromatographic analysis of excreta obtained from 34 species representing 17 families.

Toxicon, 1988
Descriptions of the principal venomous spiders in Brazil, of the genera Phoneutria, Loxosceles, Latrodectus and Scaptocosa, are given, together with a list of species and their geographical distribution. Detailed information on their habitat, behaviour and venom quantity, symptomatology of human accidents and epidemiology is given and recommendations ...

Hepatology, 1989
Nailfold capillary microscopical and hormonal investigations were carried out in 25 patients with cirrhosis of the liver and in 20 age- and sex-matched controls. Several structural and functional capillary microscopical parameters were significantly different between the group of cirrhotics as a whole and the controls; no ...

The Chemistry of Spider Toxins and Spider Silk
Angewandte Chemie International Edition in English, 1997AbstractSpiders have a bad reputation because of their predacious and hidden way of life. Nevertheless, they developed a finely tuned system, based on the use of venom and silk, which enabled them to compete successfully in evolution. Only recently has the mystery of the chemistry of their silk and venom begun to unravel, although the first ...
