Dementia Care Research and Psychosocial Factors.

Background: Despite data showing nutritional interventions high in antioxidant/anti-inflammatory properties (anthocyanin-rich foods such as blueberries/elderberries) may decrease risk of memory loss and cognitive decline, evidence for such effects in mild cognitive impairment (MCI) patients is limited. Therefore, we examined preliminary effects of American elderberry (Sambucus nigra canadensis) juice on cognition and inflammatory markers in MCI patients in a double-blind placebo-controlled trial.

Method: MCI patients (N =  24, M =  76.

Metabolic reprogramming of macrophages by PKM2 promotes IL-10 production via adenosine.

Macrophages play a crucial role in immune responses and undergo metabolic reprogramming to fulfill their functions. The tetramerization of the glycolytic enzyme pyruvate kinase M2 (PKM2) induces the production of the anti-inflammatory cytokine interleukin (IL)-10 in vivo, but the underlying mechanism remains elusive. Here, we report that PKM2 activation with the pharmacological agent TEPP-46 increases IL-10 production in LPS-activated macrophages by metabolic reprogramming, leading to the production and release of ATP from glycolysis.

Natural sampling and aliasing of marine geochemical signals.

It is well known that the sedimentary rock record is both incomplete and biased by spatially highly variable rates of sedimentation. Without absolute age constraints of sufficient resolution, the temporal correlation of spatially disjunct records is therefore problematic and uncertain, but these effects have rarely been analysed quantitatively using signal processing methods. Here we use a computational process model to illustrate and analyse how spatial and temporal geochemical records can be biased by the inherent, heterogenous processes of marine sedimentation and preservation.

Preclinical and clinical study on type 3 metabotropic glutamate receptors in Parkinson's disease.

Metabotropic glutamate (mGlu) receptors are candidate drug targets for therapeutic intervention in Parkinson's disease (PD). Here we focused on mGlu3, a receptor subtype involved in synaptic regulation and neuroinflammation. mGlu3 mice showed an enhanced nigro-striatal damage and microglial activation in response to 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP).

A group version of the OurRelationship program within residential substance use treatment: preliminary evidence for improving responses to romantic relationship conflict for those dealing with substance misuse.

The aim of this study was to pilot an adapted version of an online relationships program with residents in treatment for alcohol and other drugs (AOD). The OurRelationship (OR) Program, which is based on Integrative Behavioral Couples Therapy, was piloted in a group-based format to determine whether residents' participation in the program would result in decreases in residents' destructive responses and increases in constructive responses to relationship conflict scenarios as well as reductions in negative affect experienced during these conflict scenarios. Residents ( = 104) across six residential facilities participated in the pilot over 4 weeks.
