This study shows that both abiotic and chemical stresses could be followed through biomarker analysis and that some of these determinations are potential endpoints in a quick soil contamination assessment procedure. (C) 2008 Elsevier Ltd. All rights reserved.”
“Purpose of review

Hirschsprung disease is relatively common in children. Surgical techniques are available to remove the aganglionic bowel and reconstruct the intestinal tract. Despite many advances, these children

may still be difficult to diagnose, and may have ongoing functional problems after surgical correction.

Recent findings

The genetic basis and cause of Hirschsprung disease are becoming increasingly clearer. Definitive diagnosis is based on rectal biopsy, but more sophisticated techniques MK-2206 mouse are permitting find protocol earlier and more accurate diagnosis. Surgical correction has evolved from routine use of a colostomy and open laparotomy to one-stage transanal and laparoscopic approaches. The range of postoperative problems is reviewed so that the practicing pediatrician and primary care physician can effectively care for these children. Future advances may include better genotype-phenotype correlation and development of neuronal stem cell techniques.

Summary

Pediatricians and primary care physicians

have an important role to play in diagnosing and managing children with Hirschsprung disease.”
“Eleven alkylphenols were isolated CX-6258 from the aerial parts of Dactylis glomerata subsp. hispanica, six of them described for the first time. The structural characterization of these compounds has been elucidated by 1D and 2D NMR techniques. The fragmentation patterns of the metabolites obtained by GC-MS analysis allowed the side chain to be elucidated. The allelopathic potential

of three alkylphenols, representative of each homologous series of alkylphenols from D. glomerata subsp. hispanica, has been assayed on D. glomerata subsp. hispanica and an herbaceous coexisting species, Phleum subulatum. The bioassay results showed a high auto-stimulation values of germination and root and shoot elongation for D. glomerata subsp. hispanica at high concentrations.

“Background and Purpose: Renal mass protocol CT (RMP-CT) using multiphase abdomen and pelvis CT imaging is the mainstay for diagnosis, characterization, and follow-up for renal masses; however, it is associated with ionizing radiation to the patient. We sought to quantify the effective dose associated with RMP-CT and to determine how patient factors affect radiation exposure. Material and Methods: We retrospectively reviewed the records of 247 patients undergoing management of a small renal mass (cT(1a)) between 2005 and 2011 at our institution. Body mass index (BMI) was categorized as normal weight, overweight, obese, and morbidly obese (25, 25.
