- This study aimed to identify distinct subgroups of adults in a general population sample (N = 2,500; 52.6% females) based on their scores on three psychopathy dimensions. Using latent profile analysis, five groups were identified among males and females separately, including a psychopathic personality group. Multivariate analyses of variance showed that this latter group had higher levels of aggression, offending, substance use, attention-deficit/hyperactivity symptoms, internalizing problems, and maltreatment than most of the other groups. Associated features of males and females with a psychopathic personality were very similar; however, salient gender differences did emerge. Specifically, females with a psychopathic personality were more frequently exposed to sexual abuse, expressed more emotional difficulties, and engaged in higher levels of relational aggression. In conclusion, person-oriented analyses identified adults with a personality that looks like psychopathy, and furthered our understanding of gender similarities and differences in these adults.

Tidskriftsartikel (refereegranskat)abstract
- Vibrio campbelliiis one of the major bacterial pathogens for animals reared in aquaculture, affecting both vertebrates and invertebrates, and causes significant economic losses. It is now evident that the expressions of virulence factors in this pathogen are regulated by the density of the bacterial population. This type of regulation, termed quorum sensing (QS), is mediated by extracellular signal molecules called autoinducers. In this study, the impact of sodium ascorbate (NaAs) on the virulence ofV. campbelliiwas investigated under bothin vitroandin vivoconditions, to develop a natural anti-infective strategy to containV. campbelliiinfection in aquacultured animals. Results showed that NaAs significantly decreased swimming motility, biofilm production, and the production of virulence enzymes, such as lipase, caseinase, phospholipase, and hemolysin inV. campbellii. Consistent with this, pretreatment ofV. campbelliiwith NaAs before inoculation into the rearing water resulted in significantly increased survival of gnotobiotic brine shrimp larvae, when compared to larvae challenged with untreatedV. campbellii. Furthermore, NaAs could interfere with QS-regulated bioluminescence inV. campbellii, suggesting the QS-inhibitory activity largely determines the protective effect of NaAs toward the brine shrimp. In essence, due to the potent anti-virulence effects observed inin vitrostudies and the clinical brine shrimp-V. campbelliiinfection model, NaAs constitute a promising novel strategy for the control ofV. campbelliiinfections in aquaculture.

- Prolactin has many physiological effects and seems to be involved in the human quality of life and well-being. The aim of this study was to describe health related quality of life, fatigue and daytime sleepiness in women with untreated hyperprolactinemia. In total 32 women (mean age 37.0 ± 10.9) with verified hyperprolactinemia completed a questionnaire including questions on fatigue, measured with the Swedish version of the Fatigue Impact Scale (FIS), propensity to fall in sleep, measured with the Swedish version of the Epworth Sleepiness Scale (ESS), and Health related quality of life (HRQoL), measured by the Short-Form-36 scale (SF-36). For comparison Swedish normative data were used. The women were also interviewed regarding different symptoms related to hyperprolactinemia and the answers were analyzed using qualitative content analysis. HRQoL, as measured with SF-36, was significantly lower in all dimensions, except in physical function, compared to the Swedish reference population. Total FIS was 54.3 (41.1) and mean score on the ESS was 8.7 (4.2) indicating increased fatigue and deterioration in night sleep. The women felt very tired, and several of them rarely felt rested in the morning. The restless night sleep and the fatigue during the daytime got them to feel feeble and sometimes to find it difficult to concentrate, which affected both their mood and life in general. Women diagnosed with hyperprolactinemia reported deterioration in night sleep, increased rate of fatigue, and a reduced health related quality of life in comparison with the reference population.

- Pomatoschistus minutus show paternal care in a resource defence mating system. We investigated the effect of nest-site availability on parasitic spawning. Each experimental pool contained four potentially nest-building males, four females and nests-sites in shortage (2) or excess (6). Both treatments were conducted in two populations; one with natural nest-sites in excess, one with a nest-site shortage. Microsatellite-DNA revealed that all nest-holders had fertilized most of the eggs they tended. Yet, 35% of the nests contained eggs fertilized by another male and 14.4% of the males had performed parasitic spawning. There was no site or treatment effect. Several females spawned in two nests, which coincided with parasitic spawnings, suggesting a cost to the nest-holder in terms of lost mating success. Nest-holders with and without eggs and non-nesting males all spawned parasitically, generating a significantly lower opportunity for sexual selection compared to if there had been no parasitic spawning.

- The accumulation of biofloc in a rearing media that may bring about some adverse effects on the cultured fish, can be addressed by using a settlement tank. This study aimed to compare the production performance and flesh quality of red tilapia Oreochromis sp. in biofloc systems with and without a settlement tank. This study comprised of two treatments, i.e. biofloc system with settlement tank (Bioras) and biofloc system without settlement tank (Biofloc), each maintined in triplicates. Fish was reared in outdoor tarpaulin tanks with a diameter of 3 m and a height of 1.2 m, which were filled with about 5 m3 of water. Tilapia with an initial average weight of 100 g was cultured at an initial density of 5 kg m- 3 for 112 days with a partial harvest conducted on day 42. The fish was fed with a commercial diet containing 30.5% crude protein to apparent satiation twice a day. The results showed that the production performance of red tilapia in Bioras (75 kg) was higher than that of the conventional biofloc system (70 kg). Mild deformities and limited parasite infestation were observed in the gills of the fish housed in the Bioras system. The fish quality was similar between the treatments, except for the hardness (8.4 kgf), gumminess (3.4 kgf), and chewiness (1.8 kgf), which was higher in the fish housed in the conventional biofloc system. The increase in fish growth in Bioras system could not compensate the increase in cost for the investment and operation of the settling tank, which was about 17% higher in the Bioras system. In conclusion, the present study confirmed that the addition of a settlement tank can be beneficial in controlling biofloc biomass and could improve the growth performance, but not yet profitable for red tilapia commercial production.

- Inclusive differential cross sections dsigma(pA)/dx(F) and dsigma(pA)/dp(t)(2) for the production of K-S(0), Lambda, and (&ULambda;) over bar particles are measured at HERA in proton-induced reactions on C, Al, Ti, and W targets. The incident beam energy is 920 GeV, corresponding to roots = 41.6 GeV in the proton-nucleon system. The ratios of differential cross sections dsigma(pA)(K-S(0))/dsigma(pA)(Lambda) and dsigma(pA)((&ULambda;) over bar)/dsigma(pA) (Lambda) are measured to be 6.2 +/- 0.5 and 0.66 +/- 0.07, respectively, for x(F) approximate to -0.06. No significant dependence upon the target material is observed. Within errors, the slopes of the transverse momentum distributions da,Ald t also show no significant dependence upon the target material. The dependence of the extrapolated total cross sections sigma(pA) on the atomic mass A of the target material is discussed, and the deduced cross sections per nucleon sigma(pN) are compared with results obtained at other energies.

- Using the HERA-B detector, the b (b) over bar production cross section has been measured in 920 GeV proton collisions on carbon and titanium targets. The b (b) over bar production was tagged via inclusive bottom quark decays into J/psi by exploiting the longitudinal separation of J/psi --> l(+)l(-) decay vertices from the primary proton-nucleus interaction. Both e(+)e(-) and mu(+)mu(-) channels have been reconstructed and the combined analysis yields the cross section sigma(b (b) over bar) = 32(-12)(+14)(stat) (+6)(-7)(sys) nb/nucleon.

- Background: The W allele of the G460W polymorphism in the adducin-1 gene has been occasionally associated with increased blood pressure (BP). The aim of this study was to test whether the G460W variant is associated with BP levels and BP progression rate and whether G460W associations with BP are affected by sex, body mass index (BMI), or age. Methods: The G460W polymorphism was genotyped in the population-based Malmo Diet and Cancer-cardiovascular arm (MDC-CVA; n = 6103), of whom 53% had also been examined 11 +/- 4.4 years earlier in the Malmo Preventive Project (MPP). Results: Among subjects without antihypertensive treatment (AHT) in the MDC-CVA (n = 5009), there was no difference between carriers (38%) and noncarriers (62%) of the W allele in systolic BP (139.2 +/- 18.2 v 139.2 +/- 18.5 mm Hg; P = .99) or diastolic BP (85.9 +/- 9.1 v 86.1 +/- 9.2 mm Hg; P = .49). In subjects free from AHT in the MPP and MDC (n = 2637) there was no difference between carriers (38%) and noncarriers (62%) in progression of systolic BP (2.0 +/- 2.5 v 2.0 +/- 2.7 mm Hg/year; P = .45) or diastolic BP (0.59 +/- 1.6 v 0.56 +/- 1.5 mm Hg/year; P = .66) from MPP to MDC. At MDC-CVA BP was influenced by interaction between the G460W and BMI (P = .02 for systolic BP and P = .002 for diastolic BP) and by interaction between G460W and sex (P = .03 for systolic BP and P = .02 for diastolic BP), a result further confirmed by stratified analysis showing that female carriers of the W allele belonging to the upper tertile of BMI had increased systolic BP (146.1 +/- 18.6 v 141.2 +/- 18.6 mm Hg; P < .001), diastolic BP (88.7 +/- 8.7 v 86.1 +/- 8.7 mm Hg; P < .001), and prevalence of hypertension (72.5% v 61.8 %; P = .001). Conclusions: Our data suggest that the G460W polymorphism influences BP when BMI and sex are taken into account.
