Phenomenography: A useful methodology for midwifery research.

Aims: To outline the theoretical, philosophical, and major assumptions associated with phenomenography and then address the application of a phenomenographical approach within the context of midwifery research.

Background: Phenemonography is a little-known qualitative research approach amongst the main design traditions of phenomenology, grounded theory, case study, and ethnography more typically used within midwifery research. Phenomenography aims to describe the qualitatively different ways that people perceive, conceptualize, or experience a phenomenon.

Identification and characterization of potential performance-related gut microbiotas in broiler chickens across various feeding trials.

Three broiler feeding trials were investigated in order to identify gut bacteria consistently linked with improvements in bird performance as measured by feed efficiency. Trials were done in various geographic locations and varied in diet composition, broiler breed, and bird age. Gut microbial communities were investigated using microbial profiling.

A monoclonal antibody that interferes with the post-aggregation adhesion of Dictyostelium discoideum cells.

A monoclonal antibody that interferes with the EDTA-resistant adhesion of Dictyostelium discoideum slug cells recognised a carbohydrate epitope on four major antigens (95, 90, 35 and 30 kDa) in slug cells. The 35 and 30 kDa antigens were specific for stalks and spores, respectively. The 30 kDa antigen was identified as the cell surface glycoprotein, PsA.
