Molecular evidence for distinct modes of nutrient acquisition between visceral and neurotropic schistosomes of birds.

Trichobilharzia species are parasitic flatworms (called schistosomes or flukes) that cause important diseases in birds and humans, but very little is known about their molecular biology. Here, using a transcriptomics-bioinformatics-based approach, we explored molecular aspects pertaining to the nutritional requirements of Trichobilharzia szidati ('visceral fluke') and T. regenti ('neurotropic fluke') in their avian host.

[Nephroblastoma - 30-years period of its treatment in the University Hospital Motol, Prague].

Introduction: Nephroblastoma (Wilms tumor - WT) is the most common solid tumor of kidney in children. We present treatment development of WT at the Department of Pediatric Hematology and Oncology, Charles University in Prague, 2nd Faculty of Medicine and University Hospital Motol (KDHO) in the Czech Republic over 30 years. Patients that were treated prior to access to the International Society of Pediatric Oncology (SIOP) protocols are considered to be the historical group, then we have patients treated according to SIOP 9, SIOP 93-01 and SIOP 2001 protocols as full participants of SIOP studies.

PXO set of recombinant inbred strains of the rat: a new strain distribution pattern containing 448 markers.

A new PXO set of RIS represents a fixed F2 population derived from polydactylous (P) congenic strain SHR.Lx and oligodactylous (O) RI strain BXH2. The PXO strains were derived as a complementary set to current RIS (HXB, BXH) of the laboratory rat.
