AIMS/HYPOTHESIS: Beta cell replacement is a potential cure for type 1 diabetes. In humans, islet transplants are currently infused into the liver via the portal vein, although this site has disadvantages. Here, we investigated alternative transplantation sites for human and murine islets in recipient mice, comparing the portal vein with quadriceps muscle and kidney, liver and spleen capsules. METHODS: Murine islets were isolated from C57BL6/J mice and transplanted into syngeneic recipients...

AIMS/HYPOTHESIS: Xenotransplantation has great potential to provide beta cell replacement and thereby provide a cure for large numbers of people with type 1 diabetes. Crucial to the success of xenotransplantation is establishment of the most viable sites for transplantation. METHODS: We compared porcine islet tissue transplanted into kidney, liver and spleen in pig recipients as assessed by blood glucose levels and IVGTT. RESULTS: Kidney was the superior site for porcine islet tissue transplantation, followed by liver then spleen...

Feeding cake with remaining oil content not only provides additional dietary energy but may also enrich pork with -3 fatty acids. Limited information is available on feeding camelina cake to pigs relating to feeding safety (toxicity), growth performance, and efficacy of -3 enrichment of pork. Therefore, we evaluated the effects of feeding increasing camelina cake (12.2% crude fat) inclusions in diets for nursery and grower-finisher pigs. In total, 128 pigs (9.2 kg BW) were randomly allocated by sex to 32 nursery pens for 4 wk and were then moved and combined into 16 mixed-sex grower-finisher pens...

Feeding cake with remaining oil contributes dietary energy (fat) in addition to protein (AA) and may provide an opportunity to enrich the n-3 fatty acid content of pork. Information regarding safety, growth performance, and efficacy of feeding camelina cake to pigs is limited. We therefore evaluated the effects of camelina cake inclusion in pig nursery diets. In total, 192 pigs (9.4 kg BW) were randomly allocated by sex to 48 pens, 2 heavy and 2 light pigs per pen. Pigs were fed 1 of 4 wheat-based diets including camelina cake (0%, 6%, 12%, or 18%; variety Celine) replacing soybean meal for 4 wk...

The NF-κB family of transcription factors is essential for an effective immune response, but also controls cell metabolism, proliferation and apoptosis. Its broad relevance and the high connectivity to diverse signaling pathways require a tight control of NF-κB activity. To investigate the control of NF-κB activity by phosphorylation of the NF-κB p65 subunit, we generated a knock-in mouse model in which serine 467 (the mouse homolog of human p65 serine 468) was replaced with a non-phosphorylatable alanine (S467A)...

Multiple wasp stings can induce multiple organ dysfunction by toxic reactions. However, acute pancreatitis is a rare manifestation in wasp sting injury. A 74-year-old woman visited the emergency department by anaphylactic shock because of multiple wasp stings. Acute kidney injury, rhabdomyolysis, hepatotoxicity, and coagulopathy were developed next day. Serum amylase and lipase were elevated and an abdominal computed tomography revealed an acute pancreatitis. Urine output was recovered after 16 days of oliguria (below 500 ml/day)...

OBJECTIVES: Human embryonic stem cells (hESCs) and human induced pluripotent stem cells (hiPSCs) can generate any given cell type in the human body. One challenge for cell-replacement therapy is the efficient differentiation and expansion of large quantities of progenitor cells from pluripotent stem cells produced under good manufacturing practice (GMP). FOXA2 and SOX17 double positive definitive endoderm (DE) progenitor cells can give rise to all endoderm-derived cell types in the thymus, thyroid, lung, pancreas, liver, and gastrointestinal tract...

A wandering spleen is a rare condition characterized by the malposition of the spleen due to laxity or absence of its supporting ligaments. Although Gaucher disease generally presents with massive splenomegaly, which one of the predisposing causes of a wandering spleen, literature shows only one report of a wandering spleen in a child with Gaucher disease. In this case presentation, a 13-year-oldadolescent with Gaucher disease on enzyme replacement treatment was presented, who was detected having an abdominal mass on a routine visit and diagnosed with partial torsion of a wandering spleen associated with left lobe hypoplasia of the liver...

Hepatocyte derived from human pluripotent stem cells (hPSC-HEP) have the potential to replace presently used hepatocyte sources applied in liver disease treatment and models of drug discovery and development. Established hepatocyte differentiation protocols are effective and generate hepatocytes, which recapitulate some key features of their in vivo counterparts. However, generating mature hPSC-HEP remains a challenge. In this study, we applied transcriptomics to investigate the progress of in vitro hepatic differentiation of hPSCs at the developmental stages, definitive endoderm (DE), hepatoblasts, early hPSC-HEP, and mature hPSC-HEP, to identify functional targets that enhance efficient hepatocyte differentiation...

BACKGROUND DATA: Patients with severe acute liver failure (ALF) have extreme physiologic dysfunction and often die if transplantation is not immediately available. Patients may be supported with MARS (Baxter International Inc., Deerfield, IL) until transplantation or spontaneous recovery occurs. We present the largest series in the United States of MARS therapy as temporary hepatic replacement for ALF. METHODS: MARS was used to support patients with severe liver trauma (SLT), in ALF patients as a bridge to transplantation (BTT), and as definitive therapy for toxic ingestion or idiopathic liver failure (DT) in a level 1 trauma center and large transplant center...

An experiment was conducted in a completely randomized design to explore the replacement value of toasted guar meal (TGM) for soybean meal (SBM) in commercial broiler diets. Hypothesis was tested by including graded levels (0, 6, 9, 12, 15, and 18% of diet) of TGM to replace maize-SBM on growth performance, apparent nutrient digestibility, carcass traits, and serum parameters. A total of six iso-nitrogenous and iso-caloric diets were prepared, and each diet was fed ad libitum to 12 replicates of five chicks each from 1 to 42 days of age...

Agents that modulate immune checkpoint proteins, such as cytotoxic T-lymphocyte antigen-4 (CTLA-4) and programmed death receptor-1 (PD-1), have become a mainstay in cancer treatment. The clinical benefit afforded by immune checkpoint inhibitors can be accompanied by immune-related adverse events (irAE) that affect the skin, gastrointestinal tract, liver, and endocrine system. The types of irAEs associated with immune checkpoint inhibitors are generally consistent across tumor types. Immune-related endocrine events can affect the pituitary, thyroid, and adrenal glands, as well as other downstream target organs...

BACKGROUND: Long-term continuous intra-arterial nimodipine infusion (CIAN) is a rescue therapy option in cases of severe refractory cerebral vasospasm (CV) following acute non-traumatic subarachnoid hemorrhage (SAH). However, CIAN therapy can be associated with relevant side effects. Available studies focus on intracerebral complications, whereas extracerebral side effects are rarely examined. Aim of the present study was to generate descriptive data on the clinical course during CIAN therapy and expectable extracerebral side effects...

Combined liver/kidney transplant is the preferred transplant option for most patients with primary hyperoxaluria type 1 (PH1) since orthotopic liver transplantation replaces the deficient liver-specific AGT enzyme, thus restoring normal metabolic oxalate production. However, primary hyperoxaluria type 2 (PH2) is caused by deficient glyoxylate reductase / hydroxypyruvate reductase (GRHPR), and this enzyme is widely distributed throughout the body. Though the relative abundance and activity of GRHPR in various tissues is not clear, some evidence suggests that the majority of enzyme activity may indeed reside within the liver...
