“Background:

Genetic epilepsy with febrile seizures plus (GEFS+) is a familial epilepsy syndrome with extremely variable expressivity. Mutations in 5 genes that raise susceptibility to GEFS+ have been discovered, but they account for only a small proportion of families.\n\nMethods: We identified a 4-generation family containing 15 affected individuals with a range of phenotypes in the GEFS+ spectrum, including febrile seizures, febrile seizures plus, epilepsy, and severe epilepsy with developmental delay. We performed a genome-wide linkage analysis using microsatellite markers and then saturated the potential linkage region identified by this screen with more markers. We evaluated the evidence for linkage using both model-based and model-ree (posterior probability of linkage [PPL]) analyses. We sequenced 16 candidate genes and screened for copy number abnormalities in the minimal genetic region.\n\nResults: CYT387 price All 15 affected subjects and 1 obligate carrier shared a haplotype of markers at chromosome 6q16.3-22.31,

an 18.1-megabase region flanked by markers D6S962 and D6S287. The maximum multipoint lod score in this region was 4.68. PPL analysis indicated an 89% probability of linkage. Sequencing of 16 candidate genes did not reveal a causative mutation. No deletions or duplications were identified.\n\nConclusions: We report a novel susceptibility locus for genetic epilepsy with febrile seizures plus at 6q16.3-22.31, in which there are no known genes associated with ion channels or neurotransmitter receptors. The identification of the responsible TH-302 clinical trial gene in this region is likely to lead to the discovery of novel mechanisms of febrile seizures and epilepsy.

“We investigated sorption characteristics of two commonly used herbicides, atrazine and imazethapyr, in 101 soils with allophanic and non-allophanic clays of New Zealand using the batch equilibration technique. Soil properties, such as organic carbon (OC) content, texture,

CP-868596 in vitro pH, amount and type of clay, and cation-exchange capacity (CEC), were tested against the sorption coefficients (K(d)) of these herbicides. There was a wide variation in the sorption affinities of the soils, as the K(d) values of atrazine and imazethapyr ranged from 0.7 to 52.1 and from 0.1 to 11.3 L kg(-1), respectively. For atrazine, the sorption affinities for the allophanic set of soils (mean K(d) of 8.5 L kg(-1)) were greater than for the non-allophanic set of soils (mean K(d) of 7.5 L kg(-1)). However, no effect of allophanic status was found for imazethapyr sorption (mean K(d) of 0.82 and 0.76 L kg(-1) for allophanic and non-allophanic, respectively). None of the measured soil properties could alone explain adequately the sorption behavior of the herbicides. The variation of OC soil sorption coefficients, K(oc), was also larger for atrazine (mean K(oc) of 126.9 L kg(-1)) than for imazethapyr (mean K(oc) of 13.2 L kg(-1)).
