The choreographies of the elimination of faeces-An ethnographic study of the institutionalized body care practices of older people in different health care settings.

Aim: To explore the choreographies of the elimination of faeces of older people to gain insight into the institutionalized practices of body care of older people in hospitals and long-term care settings.

Design: A qualitative ethnographic study, drawing on a perspective of socio-material theory. Reported in accordance with the Standards for Reporting Qualitative Research.

Policies to promote breeding for lice-resistant salmon: Incentives designed for resilient and sustainable growth in aquaculture.

Sea lice represent a persistent and growing problem, challenging the resilience and growth of the salmon aquaculture industry. In this Norwegian case study, we studied and discuss how the absence of policy instruments directed at stimulating breeding for lice resistance (LR) might be explained. We found well-documented opportunities for selection progress for LR.

Body care of older people in different institutionalized settings: A systematic mapping review of international nursing research from a Scandinavian perspective.

Body care is considered a key aspect of nursing and imperative for the health, wellbeing, and dignity of older people. In Scandinavian countries, body care as a professional practice has undergone considerable changes, bringing new understandings, values, and dilemmas into nursing. A systematic mapping review was conducted with the aims of identifying and mapping international nursing research on body care of older people in different institutionalized settings in the healthcare system and to critically discuss the dominant assumptions within the research by adapting a problematization approach.

Serum albumin and HCO3- regulate separate pools of ATP in human spermatozoa.

Study Question: Do the known capacitating agents HCO(3)(-) and serum albumin regulate the generation of ATP required for sperm motility and capacitation?

Summary Answer: Serum albumin and HCO(3)(-) seem to regulate two separate pools of ATP by different mechanisms in human spermatozoa.

What Is Known Already: Sperm capacitation is a maturation process that naturally occurs in the female reproductive tract preparing the sperm cell for fertilization. It is a highly energy-depending process as it involves hyperactive motility and substantial levels of protein phosphorylation.

Structure and function of the human sperm-specific isoform of protein kinase A (PKA) catalytic subunit Cα2.

Protein kinase A (PKA) exists as several tissue-specific isoforms that through phosphorylation of serine and threonine residues of substrate proteins act as key regulators of a number of cellular processes. We here demonstrate that the human sperm-specific isoform of PKA named Cα2 is important for sperm motility and thus male fertility. Furthermore, we report on the first three-dimensional crystal structure of human apo Cα2 to 2.
