A Novel CDC42 Variant with Impaired Thymopoiesis, IL-7R Signaling, PAK1 Binding, and TCR Repertoire Diversity.

Genetic variants in cell division cycle 42 (CDC42) can manifest with dysmorphic features, autoinflammation, hemophagocytic lymphohistiocytosis, and thrombocytopenia, whereas defective thymopoiesis is a rare disease manifestation. We report a novel CDC42 missense variant (c.46A > G, p.

Proactive Health Support: Exploring Face-to-Face Start-Up Sessions Between Participants and Registered Nurses at the Onset of Telephone-Based Self-Management Support.

Proactive Health Support (PaHS) is a large-scale intervention in Denmark carried out by registered nurses (RNs) who provide self-management support to people at risk of hospital admission to enhance their health, coping, and quality of life. PaHS is initiated with a face-to-face session followed by telephone conversations. We aimed to explore the start-up sessions, including if and how the relationship between participants and RNs developed at the onset of PaHS.

Genetic liability to ADHD and substance use disorders in individuals with ADHD.

Aims: 1) To investigate whether genetic liability to attention-deficit/hyperactivity disorder (ADHD), indexed by polygenic risk scores for ADHD (PRS-ADHD), is associated with substance use disorders (SUD) in individuals with ADHD. 2) To investigate whether other individual- or family-related risk factors for SUD could mediate or confound this association.

Design: Population-based cohort study SETTING AND PARTICIPANTS: ADHD cases in the iPSYCH sample (a Danish case-cohort sample of genotyped cases with specific mental disorders), born in Denmark between 1981 and 2003 (N = 13 116).

Protective effect of in-feed specific IgM towards Yersinia ruckeri in rainbow trout.

Tightened regulations and an environmentally friendly approaches in fish production have greatly reduced the use of antibiotics but green solutions are continuously being explored. The use of functional feed may have a potential in the aquaculture sector in securing biomass and minimizing the loss from disease. In the present study, we tested the concept that blood from the fish slaughterhouse can be used for mass purification of specific antibodies which subsequently can be used for feeding fish and thereby confer protection against diseases.

Natural Pig Plasma Immunoglobulins Have Anti-Bacterial Effects: Potential for Use as Feed Supplement for Treatment of Intestinal Infections in Pigs.

There is an increasing demand for non-antibiotics solutions to control infectious disease in intensive pig production. Here, one such alternative, namely pig antibodies purified from slaughterhouse blood was investigated in order to elucidate its potential usability to control post-weaning diarrhoea (PWD), which is one of the top indications for antibiotics usage in the pig production. A very cost-efficient and rapid one-step expanded bed adsorption (EBA) chromatography procedure was used to purify pig immunoglobulin G from slaughterhouse pig plasma (more than 100 litres), resulting in >85% pure pig IgG (ppIgG).

A novel core fractionation process of human plasma by expanded bed adsorption chromatography.

Current plasma fractionation technology combines ethanol precipitation with packed bed chromatography. We have developed a novel core fractionation process comprising five expanded bed adsorption (EBA) chromatographic steps on high-density modified agarose/tungsten carbide beads. Plasma was first chromatographed on two diethyl amino-ethyl (DEAE)-tungsten carbide agarose adsorbents (respective mean particle diameters of d(v)(0.
