Fungi are commonly identified as the cause for dairy food spoilage. This can lead to substantial economic losses for the dairy industry as well as consumer dissatisfaction. In this context, biopreservation of fermented dairy products using lactic acid bacteria, propionibacteria and fungi capable of producing a large range of antifungal metabolites is of major interest. In a previous study, extensive screening was performed in vitro and in situ to select 3 dairy fermentates (derived from Acidipropionibacterium jensenii CIRM-BIA1774, Lactobacillus rhamnosus CIRM-BIA1952 and Mucor lanceolatus UBOCC-A-109193, respectively) with antifungal activity. The aim of the present study was to determine the main compounds responsible for this antifungal activity. Fifty-six known antifungal compounds as well as volatiles were targeted using different analytical methods (conventional LC and GC, GC-MS, LC-QToF). The most abundant antifungal compounds in P. jensenii-, L. rhamnosus- and M. lanceolatus-derived fermentates corresponded to propionic and acetic acids, lactic and acetic acids, and butyric acid, respectively. see more Many other antifungal compounds (organic acids, free fatty acids, volatile compounds) were identified but at lower levels. In addition, an untargeted approach using nano LC-MS/MS identified a 9-amino acid peptide derived from αs2-casein in the L. rhamnosus-derived fermentate. This peptide inhibited M. racemosus and R. mucilaginosa in vitro. This study provides new insights on the molecules involved in antifungal activities of food-grade microorganism fermentates which could be used as antifungal ingredients in the dairy industry. OBJECTIVE A common reason for organ rejection after transplantation is the lack of adherence regarding immunosuppressive medication (ISM). A variety of different aspects can promote non-adherent behavior, including the relationship between perceived benefits and concerns regarding ISM ("necessity-concerns-framework"). Little is known about the variables associated with this framework. METHODS As part of this cross-sectional study, 570 patients after kidney transplantation who participated in a structured multimodal follow-up program (KTx360°) were examined in two transplant centers in Lower Saxony. We used the Beliefs about Medicines Questionnaire (BMQ) to evaluate the patients' believes and concerns regarding their ISM. RESULTS The mean age of the participants was 51.9 (SD 14.17) years, 58.4% were men, and 25.8% had ≥12 years of school attendance. The mean time since transplantation was 65.9 months. In patients undergoing kidney transplantation, the perceived benefit of ISM mostly exceeded the concerns. We found an association between lower perceived benefits and greater concerns and lower adherence. Also, a higher perceived necessity was significantly associated with higher age and lower levels of depression and anxiety. Greater concerns were significantly associated with more symptoms of depression and anxiety, lower perceived social support, and lower kidney functioning (eGFR). CONCLUSION Even though patients after kidney transplantation usually acknowledge the importance of their ISM, they still have considerable concerns that are associated with less adherence and various psychosocial risk factors. Further longitudinal studies are needed to assess the extent to which beliefs about medication are variable and can be individually addressed to improve adherence. OBJECTIVE In research on Type D personality, its subcomponents negative affectivity (NA) and social inhibition (SI) are hypothesized to have a synergistic effect on various medical and psychosocial outcomes. As some methods to analyze Type D personality have been criticized, this study investigated whether these methods adequately detect a Type D effect. METHOD We used a simulation and two empirical illustrations to investigate each method's performance (bias, power and false positives) in detecting the Type D effect. RESULTS Our simulation showed that the two most commonly used methods to assess the Type D effect (subgroup methods) were primarily picking up the presence of NA or SI main effects, indicating that these methods might falsely suggest synergistic Type D effects. Moreover, these methods failed to detect the combined presence of the NA and SI main effects, resulting in significant Type D effects when only one of the NA/SI main effects was present. The method that best detected Type D effects modeled the continuous NA/SI main effects and their statistical interaction in a regression analysis. Reanalysis of two empirical Type D personality datasets confirmed the patterns found in our simulation. CONCLUSION This study showed that Type D effects should be modeled with a continuous interaction approach. Other approaches showed either more bias, more false positive findings or lower power. We recommend against using subgroup approaches to operationalize Type D personality, as these methods are biased, regardless of whether the Type D effect is synergistic or additive in nature. Spontaneous alternation behaviour (SAB) is the tendency to systematically alternate directional choices in successive maze arms. Originally discovered in rats, SAB has been extensively investigated in a broad range of species. In humans, however, SAB has been mostly ignored, possibly due to the difficulties arising from the use of life-size mazes. We here propose to close this gap by advancing the study of human SAB by use of virtual reality (VR). Alternation rates in humans were examined in three experiments, each deploying a specific type of virtual maze. The three virtual mazes tested 1) the effect of a concurrent cognitive task on baseline alternation rates, 2) the differential influence of locomotor and visual factors on alternation behaviour, and 3) the direction alternation in an unrestricted open space. We report a general tendency in adult human walkers to alternate walking directions in the classical T-maze context. The search for an effect of a concurrent cognitive task and the influence of locomotor and visual factors on alternation behaviour remained inconclusive. No evidence for alternation behaviour in an open space was found. Together, the experimental series elucidates the presence and characteristics of SAB in humans and paves the way for the systematic study of its neurocognitive basis.
