Coccidiosis is regarded as the parasitic disease with the greatest economic impact on the poultry industry due to reduced performance and increased mortality. A study was conducted to investigate the effects of in ovo administration of probiotics on hatchability, performance, immune organ weights, and lesion scores in broiler chicks during a mixed Eimeria infection. At embryonic day 18, 210 eggs were injected with either sterile water or 1×10(6) cfu probiotic bacteria. On day 3 post-hatch, half of the chicks from each treatment group were challenged with a mixed inoculum of Eimeria acervulina, Eimeria maxima and Eimeria tenella...

We describe a hernia of the swim bladder, with a concurrent mycotic granulomatous inflammation, and carcinoma of the swim bladder in a wild mullet (Mugil cephalus) referred for an exophytic dorsal mass. Grossly, the mass was white, soft, and composed of multiple cystic gas-containing chambers connected by a funnel-shaped tissue segment to the coelomic swim bladder. Histologically, the mass was characterized by cysts of variable size, multifocally contiguous with the subepithelial rete mirabile, supported by abundant fibrous tissue...

It is unclear if persistent splenomegaly in the presence of a negative positron emission tomography (PET) scan before allogeneic hematopoietic cell transplantation (HCT) influences post-transplantation outcomes in patients with lymphoma. We retrospectively reviewed records of 152 patients who underwent allogeneic HCT for various lymphomas. Centralized review of pretransplantation computed tomography (CT) and PET images was performed. Spleen volume (SV) was measured using the freehand volume segmentation tool in AW Workstation software (General Electric, Waukesha, WI)...

3D Statistical Shape Models (3D-SSM) are widely used for medical image segmentation. However, during segmentation, they typically perform a very limited unidirectional search for suitable landmark positions in the image, relying on weak learners or use-case specific appearance models that solely take local image information into account. As a consequence, segmentation errors arise, and results in general depend on the accuracy of a previous model initialization. Furthermore, these methods become subject to a tedious and use-case dependent parameter tuning in order to obtain optimized results...

BACKGROUND: We describe our experience with what is, to our knowledge, the first case of robotic assisted ex vivo partial splenectomy with auto-transplantation for a benign non parasitic cyst. MATERIALS AND METHODS: The patient is a 32 year-old female with a giant, benign splenic cyst causing persistent abdominal pain. Preoperative imaging showed a cystic lesion measuring 8.3 × 7.6 cm, in the middle portion of the spleen. Due to the central location of the bulky lesion a partial splenectomy was not feasible...

PURPOSE: Image non-uniformity may cause substantial problems in magnetic resonance (MR) imaging especially when a 3-T scanner is used. We evaluated the effect of image non-uniformity correction in gadolinium ethoxybenzyl-diethylenetriamine pentaacetic acid (Gd-EOB-DTPA)-enhanced MR imaging using a 3-T scanner. METHODS: Two commercially available methods for image non-uniformity correction, surface coil intensity correction (SCIC), and phased-array uniformity enhancement (PURE), were applied to Gd-EOB-DTPA-enhanced images acquired at 3-T in 20 patients...

Long-lived plasma cells are critical to humoral immunity as a lifelong source of protective antibodies. Antigen-activated B cells-with T-cell help-undergo affinity maturation within germinal centres and persist as long-lived IgG plasma cells in the bone marrow. Here we show that antigen-specific, induced IgM plasma cells also persist for a lifetime. Unlike long-lived IgG plasma cells, which develop in germinal centres and then home to the bone marrow, IgM plasma cells are primarily retained within the spleen and can develop even in the absence of germinal centres...

A CRISPR/Cas9 gene editing strategy has been remarkable in excising segments of integrated HIV-1 DNA sequences from the genome of latently infected human cell lines and by introducing InDel mutations, suppressing HIV-1 replication in patient-derived CD4+ T-cells, ex vivo. Here, we employed a short version of the Cas9 endonuclease, saCas9, together with a multiplex of guide RNAs (gRNAs) for targeting the viral DNA sequences within the 5'-LTR and the Gag gene for removing critically important segments of the viral DNA in transgenic mice and rats encompassing the HIV-1 genome...

Until recently, hantaviruses (family Bunyaviridae) were believed to originate from rodent reservoirs. However, genetically distinct hantaviruses were lately found in shrews and moles, as well as in bats from Africa and Asia. Bats (order Chiroptera) are considered important reservoir hosts for emerging human pathogens. Here, we report on the identification of a novel hantavirus, provisionally named Makokou virus (MAKV), in Noack's Roundleaf Bat (Hipposideros ruber) in Gabon, Central Africa. Phylogenetic analysis of the genomic l-segment showed that MAKV was the most closely related to other bat-borne hantaviruses and shared a most recent common ancestor with the Asian hantaviruses Xuan Son and Laibin...

Pancreatic neuroendocrine neoplasmas (PNENs) are classified into functioning & non-functioning tumors. The radical surgery is the only effective way for the cure & long-term survival. For the locoregional resectable tumors, the surgical resection is the first choice of treatment; the surgical procedures include local resection (enucleation) and standard resection. For the insulinomas and non-functioning tumors less than 2 cm, local resection (enucleation),distal pancreatectomy with spleen-preservation or segmental pancreatectomy are the commonly selected procedures...

Calcium (Ca^(2+))-activated chloride channel accessories (CLCAs) are putative anion channel-related proteins with diverse physiological functions. Exploring CLCA diversity is important for prediction of gene structure and function. In an effort to identify novel CLCA genes in Xenopus laevis, we successfully cloned and characterized a Xenopus laevis cDNA predicted to encode the xCLCA3 gene. Cloning of xCLCA3 was achieved by computational analysis, rapid amplification of cDNA ends (RACE), and a tissue distribution analysis by semi-quantitative reverse transcription (RT) PCR or real-time PCR...
