BACKGROUND Urinary metabolite measurements are often normalized to levels of the ubiquitous metabolite creatinine (CRT) to take account of variations in fluid export. Following CRT normalization, excesses of porphyrins and isoprostanes have been reported in the urines of children with neurodevelopmental disorders. It was suggested (Whiteley et al., 2006, Pediatr. Int. 2006; 48: 292-297) that ur...

Zambia is endemic for Taenia solium taeniosis and cysticercosis. In this single-centered, cross-sectional, community-based study, the role of neurocysticercosis (NCC) as a cause of epilepsy was examined. People with epilepsy (PWE, n = 56) were identified in an endemic area using a screening questionnaire followed by in-depth interviews and neurological examination. Computed tomography (CT) was ...

Ethiopian wolves, Canis simensis, are an endangered carnivore endemic to the Ethiopian highlands. Although previous studies have focused on aspects of Ethiopian wolf biology, including diet, territoriality, reproduction and infectious diseases such as rabies, little is known of their helminth parasites. In the current study, faecal samples were collected from 94 wild Ethiopian wolves in the Bal...

Abstract Toxocariasis is a zoonotic disease caused mainly by Toxocara canis and cati diagnosis in dogs cats an important tool for its control. For this reason, new coprological loop-mediated isothermal amplification (LAMP) assay was developed the simultaneous detection of these species. The primer set designed on region mitochondrial cox -1 gene. Amplification conditions were evaluated using te...

A reversed-phase h.p.l.c. system, with an ODS-Hypersil column with acetonitrile or methanol in ammonium acetate buffer as mobile phase, is described for the separation of uro-and copro-porphyrinogen isomers. The porphyrinogens are detected amperometrically with sensitivity comparable with that of the fluorescent detection of porphyrins. The effects of pH, buffer concentration and organic modifi...

ABSTRACT Coprophanaeus lancifer is a copro-necrophagous beetle endemic to the Amazon region. Although beetles belonging subfamily Scarabaeinae primarily feed on dung, some have greater diet plasticity that includes carrion, fungi, rotten fruits and invertebrates. The of scavenger C. mainly consists vertebrate carcasses, although it also attracted mammal faeces. Here, we describe first record th...

The porphyrinogens are colorless, reduced porphyrins containing 6 extra atoms of hydrogen. They have been reported to occur in biological materials by Fischer, who isolated COPRO’gen’ from the feces of his porphyria patient Petry (l), and by Watson, Schwartz, and coworkers, who showed that COPRO’gen was present in the urine of some of their patients with various porphyrias (2). Suspicions that ...
