Amazonian Dark Earths (ADE) are a unique type of soils developed through intense anthropogenic activities that transformed the original soils into Anthrosols throughout the Brazilian Amazon Basin. We conducted a comparative molecularlevel investigation of soil organic C (SOC) speciation in ADE (ages between 600 and 8700 years B.P.) and adjacent soils using ultraviolet photo-oxidation coupled wi...

dyke-davidoff-masson syndrome (ddms) is a syndrome associated with refractory epilepsy. ddms is a rare syndrome characterized by seizures, facial asymmetry, contralateral hemiplegia and mental retardation. the characteristic radiologic features are cerebral hemiatrophy with homolateral hypertrophy of the skull and sinuses. the case was an 18 years old female with seizures, hemiparesis of the ri...

the term biomining have been coined to refer to the use of microorganisms in mining processes as in the biooxidation of refractory gold minerals. the biooxidation of refractory gold ores presents similar characteristics when compared with roasting and pressure oxidation. almost without exception, microbial extraction procedures are more environmentally friendly. the isolated bacteria in this st...

objective the lennox-gastaut syndrome (lgs: the triad of intractable seizures of various types, a slow spike-wave pattern in eeg and mental retardation) is one of the most difficult epilepsy syndromes to treat. the aim of this study was to evaluate the efficacy and safety of zonisamide (zns) as add-on therapy in seizures of children with lgs. materials & methods in a quasi- experimental study, ...

PURPOSE To evaluate the anatomical and functional outcome of intravitreal dexamethasone implant for macular edema secondary to central (C) or branch (B) retinal vein occlusion (RVO) in patients with persistent macular edema (ME) refractory to intravitreal antivascular endothelial growth factor (VEGF) treatment compared to treatment naïve patients and to dexamethasone-refractory eyes switched to...

Progression of prostate cancer to androgen-refractory disease is correlated with increased expression of growth factors and receptors capable of establishing autocrine and/or paracrine growth-stimulatory loops. Many of these growth factor receptors engage Ras as part of their normal signaling activities, raising the possibility that activation of endogenous c-Ras could be a common mechanism for...

BACKGROUND Ghosal Type Hematodiaphyseal Dysplasia is an autosomal recessive disorder characterized by refractory anemia and diaphyseal bone dysplasia. CASE CHARACTERISTICS A 3 y 9 mo-old male child presented with progressive anemia and bowing of thighs. Child was found to have a previously reported homozygous point mutation c.1238G>A, (p.Arg413Glu) in Exon 16 of TBXAS1 gene. OUTCOME Low dos...
