In this paper we present a new technique for fault location based on magnetic force imaging of the magnetic field. By subtracting magnetic force images acquired selleck products at different probe-to-sample distances, the effects due to background, and probe geometry can be eliminated. We demonstrate that this method is capable of locating current carrying failure sites in model circuits with sub-micrometer uncertainty. We show how the technique can be used to map current paths in the presence of interfering currents on power supply and ground lines. (C) 2008 Elsevier B.V. All rights

“Purpose of review The purpose of the present study is to provide an updated, systematic review of the recent literature on whether nutrition is important to postpone frailty. Recent findings A systematic review of recent literature (past 12 months) identified nine studies (eight of which using a cross-sectional design) exploring the relationship between nutrition and frailty. A single randomized controlled double-blind trial was published. However, Erastin mouse being a pilot study, it was characterized by a relatively small sample size, short follow-up length (i.e., 6 months), and low statistical power. Notably, available evidence shows considerable variability in participants’ selection and assessment methods, rendering difficult direct

comparisons. Size effects or magnitude of associations across the different studies cannot also be determined. Summary There is a need for long-term, adequately powered, randomized controlled trials examining nutrition (alone and/or in combination with other appropriate interventions) as a means for postponing frailty in older persons.”
“Background: Hemoparasitoses have major importance in clinical diseases of small animals for infections are highly prevalent, IPI 145 easily transmitted and difficult to control. Clinical signs are nonspecific, but laboratory abnormalities are frequent, especially changes in serum biochemistry. In veterinary medicine, laboratorial findings may favor the diagnosis of hemoparasitoses and improve the quality of treatment given to these patients. The present study

aimed at evaluating changes in serum biochemistry in dogs with molecular diagnosis of hemoparasites (Ehrlichia canis, Anaplasma platys and Leishmania sp.). Materials, Methods & Results: Molecular diagnosis for Ehrlichia canis, Anaplasma platys and Leishmania sp. were obtained in 26 dogs. A complete serum biochemical profile was determined in biochemical analyzer COBAS Mira. Biochemical analyzes, using commercial kits from Synermed, included total and partial protein by colorimetric method, creatinine by the kinetic method, urea, alanine aminotransferase (ALT), aspartate aminotrasnferase (AST), gamma glutamyl transferase (GGT) and alkaline phosphatase by enzymatic method. Considering reference values for canine species, it was observed an increase in the average value for serum urea concentration in dogs with leishmaniasis.
