A genetically modified minipig model for Alzheimer's disease with SORL1 haploinsufficiency
The established causal genes in Alzheimer’s disease (AD), APP, PSEN1, and PSEN2, are functionally characterized using biomarkers, capturing an in vivo profile reflecting the disease’s initial preclinical phase. Mutations in SORL1, encoding the endosome recycling receptor SORLA, are found in 2%–3% of individuals with early-onset AD, and SORL1 haploinsufficiency appears to be causal for AD. To test whether SORL1 can function as an AD causal gene, we use CRISPR-Cas9-based gene editing to develop a model of SORL1 haploinsufficiency in Göttingen minipigs, taking advantage of porcine models for biomarker investigations. SORL1 haploinsufficiency in young adult minipigs is found to phenocopy the preclinical in vivo profile of AD observed with APP, PSEN1, and PSEN2, resulting in elevated levels of β-amyloid (Aβ) and tau preceding amyloid plaque formation and neurodegeneration, as observed in humans. Our study provides functional support for the theory that SORL1 haploinsufficiency leads to endosome cytopathology with biofluid hallmarks of autosomal dominant AD
The Importance of Protein in Leaf Selection of Folivorous Primates
Protein limitation has been considered a key factor in hypotheses on the evolution of life history and animal communities, suggesting that animals should prioritize protein in their food choice. This contrasts with the limited support that food selection studies have provided for such a priority in nonhuman primates, particularly for folivores. Here, we suggest that this discrepancy can be resolved if folivores only need to select for high protein leaves when average protein concentration in the habitat is low. To test the prediction, we applied meta-analyses to analyze published and unpublished results of food selection for protein and fiber concentrations from 24 studies (some with multiple species) of folivorous primates. To counter potential methodological flaws, we differentiated between methods analyzing total nitrogen and soluble protein concentrations. We used a meta-analysis to test for the effect of protein on food selection by primates and found a significant effect of soluble protein concentrations, but a non-significant effect for total nitrogen. Furthermore, selection for soluble protein was reinforced in forests where protein was less available. Selection for low fiber content was significant but unrelated to the fiber concentrations in representative leaf samples of a given forest. There was no relationship (either negative or positive) between the concentration of protein and fiber in the food or in representative samples of leaves. Overall our study suggests that protein selection is influenced by the protein availability in the environment, explaining the sometimes contradictory results in previous studies on protein selectio

Influence of Spiritual Dimensions on Suicide Risk: The Role of Regional Differences
The field of suicide prevention has been enriched by research on the association between spirituality and suicide. Many authors have suggested focusing on the various dimensions of religiosity in order to better understand the association between religion and suicidal risk, but it is unclear whether the relationship between spirituality and suicidality differs between countries with different cultures, life values, and sociohistorical experiences. To explore this, the aim of this multicenter study was to investigate the possible relationship between suicide and spirituality in Italy and Austria. In the two countries, two different groups of subjects participated: psychiatric patients and university students. The patients were evaluated with the Mini International Neuropsychiatric Interview. In addition, the following measures were used: a sociodemographic questionnaire, the Columbia-Suicide Severity Rating Scale-B, the Symptom-Checklist-90-Standard, and the Multidimensional Inventory for Religious/Spiritual Well-Being. Our results confirmed the multifactorial nature of the relation between suicide risk and the various religious/spiritual dimensions, including religious/spiritual well-being and hope immanent. However, regional differences moderated this relationship in both the clinical and nonclinical samples
