A unique set of plesiomorphic characters, and its association with an ancient gymnosperm, Araucaria araucana, have made Pentasetacus araucariae a putative relict of a lineage of gymnosperm-associated mites, itself possibly basal to all extant eriophyoids. However, the suboptimal description of this species is impeding morphological comparisons with other… (More)
This study examines the area of eye movement dysfunctions as an indicator of vulnerability to schizophrenia. Eye movement performance was investigated with three different paradigms: Smooth Pursuit Eye Movements (SPEM); Visually Guided Saccades (VGS); and Antisaccades (AS) in 21 clinically stable patients with schizophrenia, 21 of their healthy, biological… (More)
Clinical studies show that schizophrenic and depressive subjects have problems with daily life activities, and neuropsychological studies tend to explain these problems in terms of a dysexecutive syndrome. Verbal fluency and sentence arrangement are tasks considered to focus on two aspects of the dysexecutive syndrome known as initiation and supervision… (More)
We report ten cases of insufficiency fracture of the sacrum, a recently individualized pathological entity. These fractures occur in elderly women with pronounced osteopenia of the pelvis. The clinical symptoms are low back pain and sometimes mechanical radiculalgia. Histories of previous injury are rare. In 50 per cent of the cases X-ray films of the… (More)
Understanding the ecology and evolutionary history of symbionts and their hosts requires accurate taxonomic knowledge, including clear species boundaries and phylogenies. Tortoise mites (Mesostigmata: Uropodoidea) are among the most diverse arthropod associates of bark beetles (Curculionidae: Scolytinae), but their taxonomy and host associations are largely… (More)
Two new species of mites of the genus Zygoseius Berlese, Zygoseius papaversp. n. and Zygoseius lindquistisp. n., collected from moss and flood debris, respectively, in a creek in Chiapas State, Mexico, are described herein.
