Effects of a laminarin-rich algal extract on caecal microbiota composition, leukocyte counts, parasite specific immune responses and growth rate during Eimeria tenella infection of broiler chickens.

Coccidiosis, infection with protozoan parasites of genus Eimeria, is a major problem in poultry husbandry world-wide. The disease is currently managed by coccidiostats and live vaccines, but these approaches are not sustainable. Hence, it is important to identify new means to control the infection and/or ameliorate its detrimental effects on gut health.

Redefining Arctic boundaries in a changing climate: interdisciplinary perspectives on governance strategies.

The Arctic rapidly transforms due to global warming and increased human activities, triggering complex changes at unprecedented speeds that challenge conventional institutional responses. We analyse these changes through the lenses of social, political, and environmental boundaries and investigate their impacts on both inhabitants' livelihoods and the region's political framework. Employing an interdisciplinary approach, we highlight the complexities of understanding the interplay among global, regional, and local dynamics in an era where human and non-human aspects are entwined.

Genotyping of European Toxoplasma gondii strains by a new high-resolution next-generation sequencing-based method.

Purpose: A new high-resolution next-generation sequencing (NGS)-based method was established to type closely related European type II Toxoplasma gondii strains.

Methods: T. gondii field isolates were collected from different parts of Europe and assessed by whole genome sequencing (WGS).

An ultrasound-guided serratus anterior plane block with continuous local anaesthetic infusion and epidural analgesia for rib fracture pain.

Background: We compared analgesia with an ultrasound (US)-guided serratus anterior plane block (SAPB) to thoracic epidural analgesia (EA) with continuous local anaesthetic infusion in patients with unilateral multiple traumatic rib fractures. EA often carries contraindications in patients with multiple rib fractures (MRFs), whereby having alternative effective methods to treat rib fracture pain remains important to patient care. Thus, we hypothesised that both regional anaesthetic techniques would provide effective pain relief.

Phenotypic characterization of -specific chicken T-cells responding to parasite antigen re-stimulation.

Coccidiosis, caused by protozoan parasites of genus , is a disease with large impact on poultry production worldwide. It is well known that immunity is dependent on Th1-type responses. assessment of -specific T-cell activity would therefore be a valuable research tool but has so far proven difficult to establish.

Dual RNA-seq transcriptome analysis of caecal tissue during primary Eimeria tenella infection in chickens.

Background: Coccidiosis is an infectious disease with large negative impact on the poultry industry worldwide. It is an enteric infection caused by unicellular Apicomplexan parasites of the genus Eimeria.

Nurse leaders' perceptions and experiences of leading evidence: A qualitative enquiry.

Aim: The aim of this study was to describe nurse leaders' perceptions and experiences of leading evidence-based practices (EBP).

Background: Leaders can promote EBP in nursing with their own personal example and by striving to renew structures, processes and working cultures. However, previous studies have shown that nurse leaders have tended to be passive with regard to EBP.

Seroprevalence of in domestic pigs, sheep, cattle, wild boars, and moose in the Nordic-Baltic region: A systematic review and meta-analysis.

Background: is an important foodborne zoonotic parasite. Meat of infected animals is presumed to constitute a major source of human infection and may be a driver of geographical variation in the prevalence of anti- antibodies in humans, which is substantial in the Nordic-Baltic region in northern Europe. However, data on seroprevalence of in different animal species used for human consumption are scattered.

This study aimed to set up methodology to monitor parasite-specific T-cell activation in vitro using Eimeria tenella-infected chickens. A sonicated E. tenella sporozoite protein preparation was used for the activation of chicken spleen cell cultures.

Transformative agency and tensions in knowledge management-A qualitative interview study for nurse leaders.

Aim: To describe Finnish nurse leaders' perceptions of and experiences with knowledge management.

Background: Health science research has traditionally focused on knowledge transfer and research evidence instead of knowledge management, culture and organisational learning. Systematic reviews indicate a lack of awareness about nurse leaders' activities in knowledge management.

The aprosody of schizophrenia: Computationally derived acoustic phonetic underpinnings of monotone speech.

Objective: Acoustic phonetic methods are useful in examining some symptoms of schizophrenia; we used such methods to understand the underpinnings of aprosody. We hypothesized that, compared to controls and patients without clinically rated aprosody, patients with aprosody would exhibit reduced variability in: pitch (F0), jaw/mouth opening and tongue height (formant F1), tongue front/back position and/or lip rounding (formant F2), and intensity/loudness.

Methods: Audiorecorded speech was obtained from 98 patients (including 25 with clinically rated aprosody and 29 without) and 102 unaffected controls using five tasks: one describing a drawing, two based on spontaneous speech elicited through a question (Tasks 2 and 3), and two based on reading prose excerpts (Tasks 4 and 5).

A systematic review of factors influencing knowledge management and the nurse leaders' role.

Aim: To describe factors facilitating or inhibiting the development of registered nurses' competency and nurse leader's role in knowledge management.

Background: Nurses' competency directly influences patient safety and the quality and effectiveness of patient care. Challenges of nurse leaders in knowledge management include acquiring, assessing and utilising current knowledge and assessing and enhancing competency.

Pasture is a risk factor for Toxoplasma gondii infection in fattening pigs.

As consumer awareness of animal welfare increases throughout Europe, housing of pigs in more animal-friendly systems is becoming more common. There is concern that these free-range and organic management systems increase the prevalence of zoonotic meat-borne pathogens, such as Toxoplasma gondii. In this study we compared the seroprevalence of T.

Serglycin proteoglycans limit enteropathy in Trichinella spiralis-infected mice.

Background: Serglycin proteoglycans are essential for maturation of secretory granules and for the correct granular storage of cationic proteases in hematopoietic cells, e.g. mast cells.

Monitoring of local CD8β-expressing cell populations during Eimeria tenella infection of naïve and immune chickens.

The purpose of this study was to monitor abundance and activation of local CD8β-expressing T-cell populations during Eimeria tenella infections of naïve chickens and chickens immune by previous infections. Chickens were infected with E. tenella up to three times.

Expression of perforin, granzyme A and Fas ligand mRNA in caecal tissues upon Eimeria tenella infection of naïve and immune chickens.

Cytotoxic cells of the immune system may kill infected or transformed host cells via the perforin/granzyme or the Fas ligand (FasL) pathways. The purpose of this study was to determine mRNA expression of perforin, granzyme A and FasL in Eimeria tenella-infected tissues at primary infection and infection of immune chickens as an indirect measure of cytotoxic cell activity. Chickens were rendered immune by repeated E.

Associations of acoustically measured tongue/jaw movements and portion of time speaking with negative symptom severity in patients with schizophrenia in Italy and the United States.

This is the first cross-language study of the effect of schizophrenia on speech as measured by analyzing phonetic parameters with sound spectrography. We hypothesized that reduced variability in pitch and formants would be correlated with negative symptom severity in two samples of patients with schizophrenia, one from Italy, and one from the United States. Audio recordings of spontaneous speech were available from 40 patients.

CD107a as a marker of activation in chicken cytotoxic T cells.

The study aimed to evaluate cell surface mobilisation of CD107a as a general activation marker on chicken cytotoxic T cells (CTL). Experiments comprised establishment of an in vitro model for activation-induced CD107a mobilisation and design of a marker panel for the detection of CD107a mobilisation on chicken CTL isolated from different tissues. Moreover, CD107a mobilisation was analysed on CTL isolated from airways of infectious bronchitis virus (IBV)-infected birds direct ex vivo and upon in vitro stimulation.

"Meat juice" is not a homogeneous serological matrix.

Meat juice samples are used in serological assays to monitor infectious diseases within the food chain. However, evidence of inferior sensitivity, presumably due to low levels of antibodies in the meat juice compared to serum, has been presented, and it has been suggested that adjusting the dilution factor of meat juice in proportion to its blood content could improve sensitivity. In the present study, the agreement between Toxoplasma gondii-specific immunoglobulin G (IgG) levels in meat juice and serum was evaluated, and whether the level of immunoglobulins in meat juice was dependent on its blood content.

Toxoplasma gondii seroprevalence in wild boars (Sus scrofa) in Sweden and evaluation of ELISA test performance.

Toxoplasma gondii is a zoonotic protozoan parasite, infecting a wide range of warm-blooded animals. The Swedish wild boar population is expanding and increased hunting provides its meat to a growing group of consumers. We performed a spatio-temporal investigation of T.

Cytokine mRNA expression in bronchoalveolar lavage cells during Dictyocaulus viviparus infection in calves.

The purpose of this study was to monitor local cytokine responses to Dictyocaulus viviparus in calves during primary infection and re-infection. Bronchoalveolar lavage fluid (BALF) was collected weekly from experimentally infected calves and interleukin-2 (IL-2), IL-4, IL-5, IL-10 and IFN-γ mRNA expression was quantified in BALF cells. The major finding was a prominent transient increase in IL-4 mRNA expression, compared with that of uninfected calves, observed in BALF cells collected 2-3 weeks post-primary D.
