Four species of mycenoid fungi are reported as luminescent (or putatively luminescent) on the basis of specimens collected from São Paulo State, Brazil. Two of them represent new species (Mycena oculisnymphae, Resinomycena petarensis), and two represent new reports of luminescence in previously described species (M. deformis, M. globulispora). Comprehensive descriptions, illustrations, photographs, and comparisons with phenetically similar species are provided. Sequences of nuc rDNA internal transcribed spacer regions were generated for barcoding purposes and for comparisons with similar species...

BACKGROUND: The purpose of this RCT was to compare the extended plantar limb (modified) chevron osteotomy with the scarf osteotomy in correcting hallux valgus deformity and improving functional scores and patient satisfaction. METHODS: Patients were randomly assigned and kept blind to surgical allocation. Cases requiring additional procedures including the Akin osteotomy were excluded. Outcomes were measured at 1 year following surgery. RESULTS: 84 patients (109 feet) were analysed (60 modified chevron; 49 Scarf)...

BACKGROUND AND AIMS: Although mycorrhizal associations are predominantly generalist, specialized mycorrhizal interactions have repeatedly evolved in Orchidaceae, suggesting a potential role in limiting the geographical range of orchid species. In particular, the Australian orchid flora is characterized by high mycorrhizal specialization and short-range endemism. This study investigates the mycorrhizae used by Pheladenia deformis, one of the few orchid species to occur across the Australian continent...

The secretion of the hypertrophied metapleural gland of the antCrematogaster deformis contains a mixture of phenols, consisting mainly of 3-propylphenol, 3-pentylphenol, 3,4-dihydro-8-hydroxy-3-methylisocoumarin (mellein), 5-propylresorcinol, and 5-pentylresorcinol. The secretion is released, as a repellent, when the highly vulnerable petiolar-postpetiolar region of the abdomen is attacked by enemy ants. In addition, small amounts of the secretion are released regularly to serve as an antiseptic, which is considered the original function of the gland...

Different cortical malformations were produced in rats by a single dose of X-rays (200 cGy) given on different days during gestation. These include large cortical ectopic masses after irradiation on day 14; segmentation of the cerebral cortex following irradiation on days 15, 17, 19; and a four-layered "lissencephalic" cortex following irradiation on day 16. Other types of cortical malformation were produced in rats aged 0-2 days by one of the following procedures: focal cortical freezing, focal electrocoagulation, cortical aspiration, and focal brushing of the meninges with a blunt needle covered with cotton...

Morphology of the cerebral cortex was studied in fetuses on gestational Day 21 following oral administration of several doses of ethanol (for total doses of 10, 15, or 18 g/kg) to pregnant rats on gestational Days 14 and 15, a critical period for the development of the cerebral cortex. All doses of ethanol were associated with a reduction in maternal weight gain, fetal body weight, and placental weight. Only the high dose of ethanol (total dose 18 g/kg) caused significant fetal cortical thinning. Acute exposure of pregnant rats to ethanol produced dose-dependent malformations of the cerebral cortex and hippocampus in fetuses...

An iron-containing product in the acetone extract from the lichen Cladonia deformis has been investigated using chemical, spectroscopic and X-ray crystallographic methods. Visible-near UV, EPR and IR spectra indicate that the iron is present as high-spin Fe(III) and coordinates in an oxygen-containing environment arising from graciliformin (or graciliformin-like) ligands. This has been confirmed by an XAS (X-ray absorption) study using synchrotron radiation. Comparison of the EXAFS and XANES results with those obtained from a model, tris(pent-2,4-dionato)Fe(III), and detailed fitting using the single-scattering, curved-wave formalism for the EXAFS strongly supports the presence of a Fe(III) coordinated to five oxygen atoms from the graciliformin...

The characteristic features of micropolygyria were demonstrated in the cerebral and cerebellar gray matter of two cases, 5 and 16 years old males, of congenital muscular dystrophy. (Fokuyama type). The micropolygyria of the cerebral cortex showed an undifferentiated cytoarchitecture, e. g. status verrucosus deformis. On the surface of cortical molecular layer, subpial mesenchymal fibres, tangential myelin fibres and marginal glial fibres were observed to be still proliferated even at the stages examined and all the fibres were caved into the cortical cell layer associated with the molecular layer, without secondary sulcus formation...
