Wheat bin-mapped expressed sequence tags and good levels of collinearity among the wheat Snn3 regions, rice (Oryza sativa), and Brachypodium distachyon were exploited for saturation and fine mapping of the Snn3-D1 locus. Markers delineating the Snn3-D1 locus to a 1.4 cM interval will be useful for initiating positional cloning. Further characterization of how these

homoeologous genes mediate recognition of the same pathogen effector should enhance understanding of host manipulation by necrotrophic pathogens in causing disease.”
“Background: A direct relation exists between sodium and calcium excretion, but randomized studies evaluating the sustained effect of a low-salt diet on idiopathic Blasticidin S chemical structure hypercalciuria, one of the main risk factors for calcium-oxalate stone formation, are still lacking.

Objective: Our goal was to evaluate the effect of a low-salt diet on urinary calcium excretion in patients affected by idiopathic calcium nephrolithiasis.

Design: Patients affected by idiopathic calcium stone disease and hypercalciuria (> 300 mg Ca/d in men and > 250 mg Ca/d in women) were randomly assigned to receive either water therapy alone (control diet) or water therapy and a low-salt diet (low-sodium diet) for 3 mo. Twenty-four-hour urine samples

were obtained twice from

all patients: one sample at baseline on a free diet and one sample after 3 mo of treatment.

Results: LGK-974 mouse A total of 210 patients were randomly assigned to receive a control diet Selleck APR-246 (n = 102) or a low-sodium diet (n = 108); 13 patients (2 on the control diet, 11 on the low-sodium diet) withdrew from the trial. At the follow-up visit, patients on the low-sodium diet had lower urinary sodium (mean +/- SD: 68 +/- 43 mmol/d at 3 mo compared with 228 +/- 57 mmol/d at baseline; P < 0.001). Concomitant with this change, they showed lower urinary calcium (271 +/- 86 mg/d at 3 mo compared with 361 +/- 129 mg/d on the control diet, P < 0.001) and lower oxalate excretion (28 +/- 8 mg/d at 3 mo compared with 32 +/- 10 mg/d on the control diet, P = 0.001). Urinary calcium was within the normal range in 61.9% of the patients on the low-salt diet and in 34.0% of those on the control diet (difference: +27.9%; 95% CI: +14.4%, + 41.3%; P < 0.001).

Conclusion: A low-salt diet can reduce calcium excretion in hyper-calciuric stone formers. This trial was registered at clinicaltrials. gov as NCT01005082. Am J Clin Nutr 2010;91:565-70.”
