Background/Aims: Adoptive therapy with regulatory T (Treg) cells to prevent graft-versus-host disease (GVHD) would benefit from a strategy to improve homing to the sites of inflammation following hematopoietic stem cell transplantation (HSCT). Although donor-derived Treg cells have mainly been used in these models, third-party-derived Treg cells are a promising alternative for cell-based immunotherapy, as they can be screened for pathogens and cell activity, and banked for GVHD prevention...

Heterotopic gastric mucosa (HGM) is a rare anomaly in the small bowel and may be the cause of intussusception when it gets a lead point in the jejunum. All cases of intussusception due to intestinal HGM have been treated with surgical resection. A 5-year-old girl presented with chief complaints of vomiting and abdominal pain for 2 weeks. A computed tomography scan of the abdomen showed intussusception at the proximal jejunal loops. Three air reductions and one saline reduction were attempted without success...

Cubic spline function was used in a genetic evaluation to model the change of yolk proportion over the lay life. A total of 19,862 yolk proportion records of 2,324 hens was used. The evaluated submodels consisted of 3 to 6 knot models. The same knots were fitted for genetic and permanent environmental splines. The residual effects were specified to be independently and normally distributed, but with heterogeneous variance for each test week. (Co)variance components were estimated by the average information restricted maximum likelihood (AIREML) method...

Egg yolk phosvitin is one of the most phosphorylated proteins in nature, and the extraordinarily high concentration of phosphate groups in its structure provides a strong metal-binding ability. Phosvitin is known to possess various functional activities, including metal-chelating, antioxidant, emulsifying, antimicrobial, and cytotoxic activities. However, little is known about the immune-enhancing activity of phosvitin. The objective of this study was to evaluate the immune-enhancing activity of phosvitin in murine RAW 264...

Locomotion issues in broiler production may decrease performance (carcass yield and traits) and lead to high financial losses. This study evaluates the addition of glucosaminoglycans in broiler diets to minimize the lack of proper bone development and joint weakening. The experiment was conducted using 2,160 broilers randomly distributed in a factorial pattern (3 × 3) using 3 levels of glucosamine sulfate (0, 0.12, and 0.24%) and 3 levels of chondroitin sulfate addition (0, 0.08, and 0.16%). Eight repetitions were used for each treatment, distributed in 72 pens with 30 broilers each...

Gelatin was extracted from broiler (Gallus gallus domesticus) skins and analyzed to compare its physicochemical properties with those of commercial bovine gelatin. The average yield of broiler skin gelatin was 6.5% on a wet weight basis. Broiler skin gelatin had more α1-and α2-chains than β-chain and contained high molecular weight (γ-chain) polymers. Glycine was the dominant amino acid in broiler skin gelatin (20.26%), followed by proline (Pro) (15.12%) then hydroxyproline (Hyp) (11.36%). Compared to commercial bovine gelatin, broiler skin gelatin had less total imino acids (Pro and Hyp) but a higher (33...

Increasing antibiotic resistance is a major public health concern. Fluoroquinolones are used to treat and prevent poultry diseases worldwide. Fluoroquinolone resistance rates are high in their countries of use. The aim of this study was to evaluate the effect of an acids-based feed additive, as well as fluoroquinolone antibiotics, on the prevalence of antibiotic-resistant E. coli. A total of 480 broiler chickens (Ross 308) were randomly assigned to 3 treatments: a control group receiving a basal diet; a group receiving a feed additive (FA) based on formic acid, acetic acid and propionic acid; and an antibiotic enrofloxacin (AB) group given the same diet, but supplemented with enrofloxacin in water...

Two broiler chicken experiments were conducted to investigate the effects of canola meal (CM) replacing soybean meal (SBM) in diets supplemented with carbohydrase and protease on performance and partitioning of energy. First, a 2 × 2 × 2 factorial arrangement of treatments was employed to evaluate: protein meals (CM vs. SBM), carbohydrase (none or 300 mg/kg), protease (none or 200 mg/kg), and their interactions. Each treatment was fed to 6 replicated pens of 16 male broilers (Ross 308) from d 10 to 35. In the second experiment, 32 broiler chicks were used in a 2 × 2 factorial arrangement to investigate CM and carbohydrase effects on energy partitioning...

The adaptation of chickens to free-range rearing systems mainly involves the locomotory behavior, which is very different in fast-growing (FG) and slow-growing (SG) strains. This study aimed to compare the effect of moderate locomotory activity (induced and prolonged) on the blood oxidative status in a slow-growing chicken strain with that in a fast-growing one. Thirty FG (Ross 308) birds and 30 SG (Hubbard) birds were divided into 2 groups for each strain and subjected to different treatments: no exercise (the control group [C]) and 1 h of walking at 4 km/h (the exercise group [E])...

The adult myogenic population of stem cells, called satellite cells, initially develop in late-term embryos. Satellite cells are the only myogenic cell that repair damaged myofibers and increase post-hatch growth. The objective of the current study was to determine if incubation temperatures and time of hatch impact growth and pectoralis major (p. major) muscle morphology. Eggs were incubated at a constant 37.8°C; however, from d 14 to 18, the eggs were subject to 39.5°C for 0, 3, or 12 h per day. Chicks were divided into early, mid, or late hatch groups based upon the time they emerged from the shell...

Mycoplasma gallisepticum (MG) is a bacterial pathogen that causes production losses in layer chickens. To combat MG, multiage layer facilities vaccinate pullets by either spray or eye-drop vaccination. The objective in this study was to evaluate the use of in ovo vaccination as a potential alternative for MG vaccination. Layer embryos at 18 d of incubation were either not-injected (control), or were hand-injected with either commercial Marek's disease vaccine diluent alone or with a high, medium, low, or very low dosage of a live attenuated strain F (FMG) vaccine suspended in the commercial diluent...

Chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids (CLIPPERS) is a central nervous system inflammatory syndrome predominantly affecting the brainstem, cerebellum, and spinal cord. Following its initial description, the salient features of CLIPPERS have been confirmed and expanded upon, but the lack of formalized diagnostic criteria has led to reports of patients with dissimilar features purported to have CLIPPERS. We evaluated clinical, radiological and pathological features of patients referred for suspected CLIPPERS and propose diagnostic criteria to discriminate CLIPPERS from non-CLIPPERS aetiologies...

Timely initiation of effective therapy is crucial for preventing disability in multiple sclerosis; however, treatment response varies greatly among patients. Comprehensive predictive models of individual treatment response are lacking. Our aims were: (i) to develop predictive algorithms for individual treatment response using demographic, clinical and paraclinical predictors in patients with multiple sclerosis; and (ii) to evaluate accuracy, and internal and external validity of these algorithms. This study evaluated 27 demographic, clinical and paraclinical predictors of individual response to seven disease-modifying therapies in MSBase, a large global cohort study...

See Schiff (doi:10.1093/awx209) for a scientific commentary on this article. Patients with acute severe traumatic brain injury may recover consciousness before self-expression. Without behavioural evidence of consciousness at the bedside, clinicians may render an inaccurate prognosis, increasing the likelihood of withholding life-sustaining therapies or denying rehabilitative services. Task-based functional magnetic resonance imaging and electroencephalography techniques have revealed covert consciousness in the chronic setting, but these techniques have not been tested in the intensive care unit...
