Although some commercial vaccines against grass carp reovirus (GCRV) are available, given the many varieties of GCRV and limited types of vaccines, the disease caused by GCRV remains a major problem, which leads to economic losses in grass carp aquaculture. A reovirus strain (GCRV-HN14) was recently isolated from local diseased fish in our laboratory. The S11 segment of GCRV-HN14 was speculated to encode the virus capsid protein VP35. In our study, the S11 segment was cloned into the eukaryotic expression vector pcDNA3...

Vaccination of chicks with Salmonella (S.) Typhimurium aroA deletion mutants has previously been shown to inhibit intestinal colonization of wild-type S. Typhimurium strains. In Australia, Bioproperties VaxSafe™ STM1 strain is the only licensed and commercially available S. Typhimurium vaccine. This vaccine is a live attenuated aroA deletion mutant. Currently, it is recommended that the first dose of the STM1 vaccine is administered through coarse spray. It is unclear whether this mode of administration effectively permits intestinal colonization...

BACKGROUND AND OBJECTIVE: Adrenal tumours occur on adrenal glands surrounded by organs and osteoid. These tumours can be categorized as either functional, non-functional, malign, or benign. Depending on their appearance in the abdomen, adrenal tumours can arise from one adrenal gland (unilateral) or from both adrenal glands (bilateral) and can connect with other organs, including the liver, spleen, pancreas, etc. This connection phenomenon constitutes the most important handicap against adrenal tumour segmentation...

People broadly use medicinal plants although their safety and efficacy are often neglected. Several Cactaceae plants are used for medicinal purposes, but Pilosocereus gounellei (xique-xique) has been little studied for their pharmacological properties. In this study, a saline extract from Pilosocereus gounellei stem was evaluated for acute toxicity, effects on motor function, and antinociceptive activity in mice. Thin-layer chromatography and high-performance liquid chromatography revealed the presence of flavonoids and reducing sugars...

Background: Chronic Hepatitis C virus (HCV) infection and liver cirrhosis may be associated with atherosclerosis and coronary artery disease (CAD). There are two phases to atherosclerosis, Subclinical and Clinical. Assessment of atherosclerosis may be started at its Subclinical phase by the evaluation of Epicardial Fat Thickness (EpFT) and Carotid Intima Thickness (CIMT). Aim of the study: The aim of the study was to evaluate Clinical and Subclinical atherosclerosis in chronic HCV patients with and without liver cirrhosis by evaluating CIMT and EpFT and correlating the results with Child-Pugh functional scoring of cirrhosis as well as with ultrasound and laboratory parameters that define the severity of liver disease...

The ability of immunoglobulin (Ig) to recognize pathogens is critical for optimal immune fitness. Early events that shape preimmune Ig repertoires, expressed on IgM+ IgD+ B cells as B cell receptors (BCRs), are poorly defined. Here, we studied germ-free mice and conventionalized littermates to explore the hypothesis that symbiotic microbes help shape the preimmune Ig repertoire. Ig-binding assays showed that exposure to conventional microbial symbionts enriched frequencies of antibacterial IgM+ IgD+ B cells in intestine and spleen...

Recent advances in 3D fully convolutional networks (FCN) have made it feasible to produce dense voxel-wise predictions of volumetric images. In this work, we show that a multi-class 3D FCN trained on manually labeled CT scans of several anatomical structures (ranging from the large organs to thin vessels) can achieve competitive segmentation results, while avoiding the need for handcrafting features or training class-specific models. To this end, we propose a two-stage, coarse-to-fine approach that will first use a 3D FCN to roughly define a candidate region, which will then be used as input to a second 3D FCN...

The red panda ( Ailurus fulgens) is classified as an endangered species by the International Union for Conservation of Nature and Natural Resources. The aim of this study was to describe the normal radiographic abdominal anatomy in red pandas to provide guidance for clinical use. Radiography of the abdomen was performed in nine captive red pandas during their annual health examinations. Seven of nine animals had six lumbar vertebrae. The sacrum consisted mainly (8/9) of three fused segments. Hypaxial muscles were easily seen in animals weighing 5 kg and above...

Geese are capable of digesting and making use of a high-fiber diet, but the mechanism is not well understood and would be of great significance for the development and utilization of roughage resources. In this study, we investigated the effect of dietary fiber (source: corn stover and alfalfa, included at 5% or 8%) on microflora in goose intestines. We used 35-day-old Carlos geese in which we first studied the influence of fiber ingestion on diet digestibility and immune organ indices of geese and found that high dietary fiber (8% content) significantly increased feed intake, the digestibility of neutral and acid detergent fiber, and thymus, bursa, and spleen size...

REVIEW

Comprising the majority of leukocytes in humans, neutrophils are the first immune cells to respond to inflammatory or infectious etiologies and are crucial participants in the proper functioning of both innate and adaptive immune responses. From their initial appearance in the liver, thymus, and spleen at around the eighth week of human gestation to their generation in large numbers in the bone marrow at the end of term gestation, the differentiation of the pluripotent hematopoietic stem cell into a mature, segmented neutrophil is a highly controlled process where the transcriptional regulators C/EBP-α and C/EBP-ε play a vital role...

Transarterial chemoembolization (TACE) with drug-eluting beads (DC beads) may enhance drug delivery to tumours and reduce systemic toxicity. TACE with DC beads leads to significantly fewer serious side-effects compared with conventional TACE. A 66-year-old man with hepatocellular carcinoma (HCC) complained of continuous abdominal pain 1 month after TACE with DC beads. At the time of TACE, angiography revealed severe stenosis of both hepatic arteries. The diagnostic work up on admission suggested severe bile duct injury with regional bile duct dilatation, segmental liver and spleen infarction, necrotizing pancreatitis, as well as gastric and duodenal ulcers...

Anatomical evaluation of multiple abdominal and thoracic organs is generally performed with computed tomography images. Owing to the large field-of-view of these images, automatic segmentation strategies are typically required, facilitating the clinical evaluation. Multi-atlas segmentation (MAS) strategies have been widely used with this process, requiring multiple alignments between the target image and the set of known datasets, and subsequently fusing the alignment results to obtain the final segmentation...
