The objective of the present study was to test the association between Borderline Personality Disorder (BPD) and the cathecolamine-O-methyl-transferase (COMT) low-activity (Met158) single nucleotide polymorphism (SNP). In this case-control study, DNA was obtained from venous blood of 19 BPD patients and 36 healthy subjects. COMT-Val158Met single-nucleotide polymorphism was genotyped by predesigned SNP assay. The COMT Met158 allele was over-represented in patients with BPD in comparison to normal subjects (68.4% vs 44.4%, respectively; Fisher exact test, p = .02). In terms of genotype, the Met158Met subjects were more frequent in patients versus controls (47.4% vs 22.2%, respectively), whereas the high-activity genotype Val158Val was under-represented (10.5% vs 33.3%, respectively). The allele encoding for the COMT with low enzymatic efficiency was found to be over-represented in BPD, possibly resulting in excessive synaptic dopaminergic activity and ultimately affecting externalizing behaviours, such as impulsivity and aggressiveness. 相似文献

The development of new human skeletal muscle tissue is an alternative approach to the replacement of tissue after severe damage, for example in the case of traumatic injury, where surgical reconstruction is often needed following major loss of natural tissue. Treatment to date has involved the transfer of muscle tissue from other sites, resulting in a functional loss and volume deficiency of donor sites. Approaches that seek to eliminate these problems include the relatively new solution of skeletal muscle engineering. Here there are two main components to consider: (a) the cells with their regenerative potential; and (b) the polymeric structure onto which cells are seeded and where they must perform their activities. In this paper we describe well‐defined two‐ and three‐dimensional polymeric structures able to drive the myoblast process of adhesion, proliferation and differentiation. We examine a series of polymers and protein adhesions with which to functionalize the structures, and cell‐seeding methods, with a view to defining the optimal protocol for engineering skeletal muscle tissue. All polymer samples were tested for their mechanical and biological properties, to support the validity of our results in the real context of muscle tissue engineering.

In highly hypnotizable individuals (highs), postural control is more independent of sensory information than in low hypnotizable subjects (lows). The aim of the study was to find out whether locomotion is also less affected in highs than in lows by visual suppression and changes in the neck proprioceptive input. Eighteen highs and 20 lows were asked to walk straight ahead, blindfolded, in basal conditions (face forward), during real and imagined right/left head rotation and mental computation. Highs detected deviations from the straight trajectory better than lows. Their walking direction was more straight during basal conditions and less influenced than the lows' one by mental computation and real/imagined rotation of the head. The results confirm highs' lower dependence on sensory inputs, although this cannot be definitely attributed to a better internal representation of space or to higher behavioral automaticity. 相似文献
