INTRODUCTION: Biliary reconstruction is a cornerstone of living-donor liver transplantation (LDLT). The routine uses of trans-anastomotic biliary catheters in biliary reconstruction had been a controversial issue. We describe a rare complication related to the use of trans-anastomotic biliary catheter after LDLT. In this case, intestinal obstruction occurred early after LDLT due to internal herniation of the small bowel around trans-anastomotic biliary catheter. PRESENTATION: A 42 years male patient with end stage liver disease underwent LDLT utilizing a right hemi-liver graft...

Pharmaceutical drugs, such as diclofenac (DCF), are frequently detected in the marine environment, and recent evidence has pointed out their toxicity to non-target marine biota. Concomitantly, altered environmental conditions associated with climate change (e.g. warming and acidification) can also affect the physiology of marine organisms. Yet, the underlying interactions between these environmental stressors (pharmaceutical exposure and climate change-related stressors) still require a deeper understanding...

Maternal nutrient restriction during gestation can exert long-term negative effects on offspring health and performance. Arginine supplementation may rescue some of the negative effects elicited by maternal nutrient restriction. We tested the hypothesis that maternal arginine supplementation during gestation would rescue deleterious effects of nutrient restriction on in vitro O2 consumption in the liver and jejunum and hypothalamic protein expression of proopiomelanocortin (POMC), neuropeptide Y (NPY), agouti-related peptide (AgRP), and neuronal nitric oxide synthase (nNOS), and the colocalization of nNOS and active phosphor-signal transducer and activator of transcription 3 (pSTAT3) in female offspring...

In response to a number of late, repetitive bleeding episodes from the site of the enteric anastomosis, we herein analyze the clinical courses and etiologies of 379 consecutively performed pancreas transplants between January 2000 and December 2016. Duodenojejunostomies for enteric drainage were performed at the upper jejunum in a side to side, double layer fashion. Five patients (1.3%) developed recurrent late hemorrhagic episodes originating from the graft duodenal anastomosis. Bleeding from the anastomotic site was associated with hematochezia, hemodynamic instability and decrease of serum hemoglobin...

Human lead (Pb) exposure induces many adverse health effects, including some related to lead accumulation in organs. Although lead bio-distribution in the body has been described, the molecular mechanism underlying distribution and excretion is not well understood. The transport of essential and toxic metals is principally mediated by proteins. How lead affects the expression of metal transporter proteins in the principal metal excretory organs, i.e., the liver and kidney, is unknown. Considering that co-administration of melatonin and lead reduces the toxic effects of lead and lead levels in the blood in vivo, we examined how lead and co-administration of lead and melatonin affect the gene and protein expression of metal transporter proteins (ZIP8, ZIP14, CTR1 and DMT1) in these organs...

Structural changes in the liver of CBA mice were studied during the development of experimental hepatocarcinoma-29 inoculated into the hip. A decrease in the volume density of hepatocyte cytoplasm, mitochondria, endoplasmic reticulum, and lipid inclusions and an increase in the volume density of lysosomal structures during tumor growth were observed. All stages of intracellular autophagy were recorded by the method of electron microscopy. These stages included the appearance of autophagosomes, autophagolysosomes, and secondary lysosomes in the hepatocyte cytoplasm...

BACKGROUND: The aim of this work was to confirm that post-selective internal radiation therapy (SIRT) 90 Y-PET/CT-based dosimetry correlates with lesion metabolic response and to determine its correlation with overall survival (OS) in liver-only metastases from colorectal cancer (mCRC) patients treated with SIRT. Twenty-four mCRC patients underwent pre/post-SIRT FDG-PET/CT and post-SIRT 90 Y-PET/CT. Lesions delineated on pre/post-SIRT FDG-PET/CT were classified as non-metabolic responders (total lesion glycolysis (TLG)-decrease < 15%) and high-metabolic responders (TLG-decrease ≥ 50%)...

Ovine and caprine malignant theileriosis (OCMT), a critical condition in small ruminant production, causes lethal infections. In September 2016, a total number of 400 goats of Marghoz breed (the largest population of goat breed in Iran), in northwest of Iran, were examined for approximately 25 pre-partum abortions and 7 goats' mortality for a period of 3 days. A dead goat and her aborted fetus were brought into the Urmia Veterinary Hospital for further diagnostic investigations. The microbiological assessments including direct microscopical examination of the vaginal discharges and placentome with respect to the differential staining (Gram's staining method), conventional pure culturing, fetal abomasal contents, and the liver were negative...

Phototherapy and photochemotherapy (PUVA) are important treatment modalities in inflammatory skin diseases such as psoriasis and atopic dermatitis as well as in cutaneous T‑cell lymphoma (e.g., mycosis fungoides/Sezary syndrome). Many of these skin diseases are accompanied by distracting pruritus. In addition, patients may suffer from intense pruritus in systemic diseases of the kidney and liver as well as of the endocrine and hematopoietic system. UV-light during phototherapy is capable of not only improving the inflammatory skin lesions but also of reducing the pruritus in skin and systemic diseases...

Severe liver abscess infections caused by hypervirulent clonal-group CG23 Klebsiella pneumoniae have been increasingly reported since the mid-1980s. Strains typically possess several virulence factors including an integrative, conjugative element ICEKp encoding the siderophore yersiniabactin and genotoxin colibactin. Here we investigate CG23's evolutionary history, showing several deep-branching sublineages associated with distinct ICEKp acquisitions. Over 80% of liver abscess isolates belong to sublineage CG23-I, which emerged in ~1928 following acquisition of ICEKp10 (encoding yersiniabactin and colibactin), and then disseminated globally within the human population...
