Fundamental biases in affective information processing are modulated by individual differences in the emotional response to environmental stimuli that may be partly based on the individual's genetic make-up. To extend prior dot probe studies on attention genetics, we used a visual-search paradigm (VSP) with pictures of angry and happy faces of both sexes as targets, neutral faces as distractors, and a varying set size. Participants were selected a priori depending on their 5-HTTLPR (s/s, s/l, l/l; on a constant rs25531 A-allele background) and COMTval158met (val/val, valmet, met/met) genotypes and were matched for sex and age. We demonstrate a bias towards angry male faces (as opposed to happy male faces) irrespective of 5-HTTLPR genotype in the first experimental block that was maintained during the second experimental block only in carriers of the s-allele, which implies differential habituation processes. While a bias towards angry male faces was observed irrespective of COMTval158met genotype, only individuals with the val/val genotype exhibited a bias towards a happy female face (as opposed to an angry female face). In sum, our results both replicate and extend prior findings in the field of attention genetics and add important pieces of information to the research on attentional biases in emotion processing.

Three mares underwent diagnostic laparoscopy because of suspicion of post-partum uterine ruptures. All three horses showed clinical signs of a uterine rupture between 1 and 3 days after parturition and underwent diagnostic laparoscopy. In all cases a full thickness uterine rupture could be detected and was sutured laparoscopically. Availability of suture material and surgeon experience were responsible for the surgical methods chosen for repair. In the first case, a hand-assisted laparoscopic approach was chosen for suturing the ruptured uterus, whereas in the other cases the approach was entirely laparoscopic. In the second case, extracorporeal knots were used for the repair and in the last case described a barbed loop suture was available for closure of the uterus. Two of three mares were alive for at least 12 months after surgery without any abdominal problems. One of these mares delivered a healthy foal 2 years after surgery. The remaining mare died 3 months after surgery but no necropsy was done. Laparoscopy should be considered for post-partum mares with signs of peritonitis to access the uterus and repair a rupture if it is accessible. A laparoscopic approach using intracorporeal knots or barbed sutures for the repair of the uterine rupture as well as a handassisted laparoscopic approach are feasible. The use of the barbed suture for intracorporeal closure makes the minimal invasive laparoscopic technique easier to perform.
