Associations Between Anticipatory Grief and Post-Bereavement Depression and Post-Loss Grief of Family Members of Dying Patients With Cancer in Palliative Care Units: A Cohort Study.

Anticipatory grief is associated with post-bereavement grief; however, reports on the influence of pre-loss depression are limited. Therefore, we investigated the association between the anticipatory grief of family members and post-loss and post-depression grief adjusted for pre-loss depression. This cohort study included the family members of dying patients with cancer.

Acoustic measurement and statistical characterization of direct-printed, variable-porosity aluminum foams.

Additive manufacturing has expanded greatly in recent years with the promise of being able to create complex and custom structures at will. Enhanced control over the microstructure properties, such as percent porosity, is valuable to the acoustic design of materials. In this work, aluminum foams are fabricated using a modified powder bed fusion method, which enables voxel-by-voxel printing of structures ranging from fully dense to approximately 50% porosity.

Effects of sampling seasons and locations on fish environmental DNA metabarcoding in dam reservoirs.

Environmental DNA (eDNA) analysis has seen rapid development in the last decade, as a novel biodiversity monitoring method. Previous studies have evaluated optimal strategies, at several experimental steps of eDNA metabarcoding, for the simultaneous detection of fish species. However, optimal sampling strategies, especially the season and the location of water sampling, have not been evaluated thoroughly.

New PCR primers for metabarcoding environmental DNA from freshwater eels, genus Anguilla.

Freshwater eels of the genus Anguilla comprise 16 species that include three subspecies and are characterized by their unique catadromous life cycles. Their life histories and nocturnal life styles make it difficult to observe them in freshwater and marine habitats. To investigate their distribution and ecology in aquatic environments, we developed new PCR primers for metabarcoding environmental DNA (eDNA) from Anguilla.
