Two major quantitative trait loci (QTL) for morphine consumption and preference exist between these strains on chromosomes (Chrs.) 6 and 10 when
the two-bottle choice involves morphine in saccharin vs quinine in saccharin. Here, we report the refinement of the Chr. 10 QTL in subcongenic strains of D2. B6-Mop2 congenic mice described previously. With these subcongenic mouse strains, we have divided the introgressed region of Chr. 10 containing the QTL gene(s) into two segments, one between the acromere and Stxbp5 (in D2.B6-Mop2-P1 mice) and the other between marker D10Mit211 and marker D10Mit51 (in D2.B6-Mop2-D1 mice). We find that, similar to B6 mice, the D2.B6-Mop2-P1 congenic mice exhibit a strong preference for morphine over quinine, whereas D2.B6-Mop2-D1 check details Givinostat chemical structure congenic mice avoid morphine (similar to D2 mice). We have also created a line of double congenic mice, B6.D2-Mop2. Qui, which contains both Chr. 10 and Chr. 6 QTL. We find that they are intermediate in their morphine preference scores when compared with B6 and D2 animals. Overall, these data suggest that the gene(s) involved in morphine preference in the morphine-quinine two-bottle choice paradigm are contained within the proximal region of Chr. 10 (which
harbors Oprm1) between the acromere and Stxbp5, as well as on distal Chr. 6 between marker D6Mit10 and the telomere.”
“The storage conditions of the donor kidney may influence the deleterious consequences of ischemia/reperfusion (IR), which remains a major source of complications in clinical practice. Delayed graft function (DGF), seen in 20% to 50% of transplanted cadaver kidneys, is a major risk factor affecting early and long-term graft survival, patient management, and costs of transplantation. Cold preservation plays a key role in this process and is based on hypothermia and high potassium solutions. In this review, the authors focused on the major molecular mechanisms of cold storage (CS) injury at the cellular level, which have been recently
evidenced with modern Amoxicillin biochemical and cell biologic methods. These newly uncovered aspects of cold preservation injury are often not fully addressed by preservation solutions in current clinical practice. The role of new molecules such as polyethylene glycol (PEG) is presented and their properties are analyzed in the organ preservation context. PEG improves organ function recovery and reduces inflammation and fibrosis development in several models. Because organs shortage is also a real public health problem, organs from non-heart beating donors or marginal donors are now used to expand pool of organs. As a consequence, the development of better organ preservation methods remains a major target and deserves scientific consideration.”
