Rabbit Anti-Human OPRM1 (Phospho-Ser375) polyclonal antibody

Dogs are a social species and, as such, often exhibit behaviors to maintain contact with their family. Separation-related behaviors are commonly seen in companion dogs and are second only to aggression as the reason for referral to behavior specialists. Separation anxiety profoundly affects the welfare of the dog and owner, and their relationship. A small proportion of dogs diagnosed with separation anxiety also maintain close proximity to one person in the household, a behavior labeled as "hyperattachment" by some authors. Opinions in the literature vary as to the role of attachment in the etiology of separation anxiety. Four candidate genes that were previously associated with social affiliative behaviors and attachment in a range of rodents and primates were analyzed for case-control association with separation-related distress in 42 Australian golden retrievers. Four haplotypes were taken forward and assessed for quantitative allelic association in 55 golden retrievers (including the initial test set). By analysis of variance, a single risk variant haplotype within 500 kilobases of drd2 maintained significance in the wider sample set. (C) 2016 Elsevier Inc. All rights reserved.

Aims Our study aimed to evaluate the impacts of the cytochrome P450 (CYP) 2B6-G516T and CYP2D6 genetic polymorphisms on pharmacokinetic and clinical parameters in patients receiving methadone maintenance treatment. Methods Opioid PhArmacoLogy (OPAL) was a clinical survey of the sociodemographic characteristics, history and consequences of pathology associated with methadone maintenance treatment response and current addictive comorbidities. A subgroup of 72 methadone patients was genotyped. Results When comparing the three CYP2B6 genotype groups, the methadone (R)- and (S)-methadone enantiomer concentrations/doses (concentrations relative to doses) were different (P = .029, P = .0019). The CYP2D6 phenotypes did not seem to be relevant with regard to methadone levels. On multivariate analysis, neither the CYP2B6 genotype nor the CYP2D6 phenotype explained the (R)-methadone concentration/dose values (P = .92; P = .86); the (S)-methadone concentration/dose values (P = .052; P = .95 [although there was a difference between the TT group and GT and GG groups {P = .019}]); or opiate cessation (P = .12; P = .90). Conclusion The genotyping of CYP2B6 G516T could be an interesting tool to explore methadone intervariability.
