Depressive Symptoms and Amyloid Pathology.

Importance: Depressive symptoms are associated with cognitive decline in older individuals. Uncertainty about underlying mechanisms hampers diagnostic and therapeutic efforts. This large-scale study aimed to elucidate the association between depressive symptoms and amyloid pathology.

Light-dependent variations in fatty acid profiles and gene expression in Antarctic microalgal cultures.

Photosynthetic eukaryotic microalgae are key primary producers in the Antarctic sea ice environment. Anticipated changes in sea ice thickness and snow load due to climate change may cause substantial shifts in available light to these ice-associated organisms. This study used a laboratory-based experiment to investigate how light levels, simulating different sea ice and snow thicknesses, affect fatty acid (FA) composition in two ice associated microalgae species, the pennate diatom Nitzschia cf.

Distance and Orientation Dependence of Triplet-Triplet Energy Transfer Couplings Based on Nonorthogonal Multireference Wave Functions.

Triplet-triplet energy transfer (TEnT) is of particular interest in various photochemical, photobiological, and energy science processes. It involves the exchange of spin and energy of electrons between two molecular fragments. Here, quasi-diabatic self-consistent field solutions were used to obtain the diabatic states involved in TEnT.

The Mellow Babies parenting programme: role of group processes and interpersonal change mechanisms.

Introduction: Group-based parenting programmes have specific mechanisms of change compared to individual delivery. The Mechanisms of Action in Group-based Interventions framework (MAGI); distinguishes between interpersonal and intrapersonal mechanisms of change. This paper articulates a theory of change for Mellow Babies, a 14-week attachment-based group parenting programme for mothers of infants aged under 18 months, identifying the inter and intrapersonal change processes.

The importance of group factors in the delivery of group-based parenting programmes: a process evaluation of Mellow Babies.

Introduction: The role of the group has been largely overlooked within evaluations of group-based parenting programmes. Group contextual factors, including size and level of homogeneity, may impact on essential group processes, such as group identification and cohesion, that are necessary to activate interpersonal change mechanisms and attain programme outcomes. This process evaluation of Mellow Babies, a 14-week attachment-based group parenting programme for mothers of infants aged under 18 months, explores how group context affected mother and practitioner experiences of the programme.
