Inferior vena cava tumor thrombus that directly infiltrated from paracaval lymph node metastases in a patient with recurrent hepatocellular carcinoma.

Herein, we present the case of a patient with recurrent hepatocellular carcinoma (HCC) who had paracaval lymph node (LN) metastases with an inferior vena cava (IVC) tumor thrombus after a hepatectomy. A 65-year-old man with chronic hepatitis B virus infection received an extended anterior segmentectomy because of two hepatic tumors, located in segments 7 and 8. Histological examination of both resected specimens showed mostly moderately differentiated HCC with some poorly differentiated areas, and liver cirrhosis (A2/F4).

Exacerbation and remission of pulmonary micronodules with lymphangioleiomyomatosis around the time of childbirth.

We present a case of multifocal micronodular pneumocyte hyperplasia (MMPH), lymphangiomyomatosis (LAM) and angiomyolipoma (AML) in a 33-year-old woman with tuberous sclerosis complex referred to us during her first pregnancy. Computed tomography of the chest showed diffuse micronodules and cysts in both lungs. Compared to those before pregnancy, the number of micronodules increased evidently.

Attenuation of portal hypertension by continuous portal infusion of PGE1 and immunologic impact in adult-to-adult living-donor liver transplantation.

Background: Small-for-size syndrome remains the greatest limiting factor of expanding segmental liver transplantation from living donors. Portal hyperperfusion is considered to substantially contribute to small-for-size syndrome. We investigated the impact of continuous portal infusion of prostaglandin E1 (PGE1) on small-for-size grafts (SFSGs) in adult-to-adult living-donor liver transplantation (LDLT).

Multi-system progressive angiomatosis in a dog resembling blue rubber bleb nevus syndrome in humans.

A six-year-old, neutered, female golden retriever was presented with generalised, dark purple to black cutaneous nodules and gastrointestinal haemorrhage. Histopathologically, all cutaneous nodules were diagnosed as benign cavernous haemangiomas. Endoscopic analysis revealed similar nodules in the oesophagus, stomach and duodenum.

Expression of recipient CD47 on rat insulinoma cell xenografts prevents macrophage-mediated rejection through SIRPα inhibitory signaling in mice.

We have previously proven that the interspecies incompatibility of CD47 is responsible for in vitro phagocytosis of xenogeneic cells by host macrophages. Utilizing an in vivo model in the present study, we investigated whether genetically engineered expression of mouse CD47 in rat insulinoma cells (INS-1E) could inhibit macrophage-mediated xenograft rejection. INS-1E cells transfected with the pRc/CMV-mouse CD47 vector (mCD47-INS-1E) induced SIRPα-tyrosine phosphorylation in mouse macrophages in vitro, whereas cells transfected with the control vector (cont-INS-1E) did not.

Usefulness of cefovecin disk-diffusion test for predicting mecA gene-containing strains of Staphylococcus pseudintermedius and clinical efficacy of cefovecin in dogs with superficial pyoderma.

Background: Cefovecin has been widely used to treat skin infections in dogs. The relationship of the cefovecin disk-diffusion test results to the presence of the mecA gene and the clinical efficacy of cefovecin have not been fully evaluated.

Hypothesis/objectives: To determine the usefulness of an in vitro cefovecin disk-diffusion test in predicting the presence of the mecA gene in Staphylococcus pseudintermedius, as well as the in vivo efficacy of cefovecin therapy in dogs with superficial pyoderma.

Skin lipid profiling in normal and seborrhoeic shih tzu dogs.

Background: Seborrhoea is a clinical condition resulting in excessive lipid and/or scale on the skin and is a common and important skin disease of dogs. However, there is little information on the skin surface lipid composition of dogs with seborrhoea.

Hypothesis/objectives: To compare skin surface lipid profiles in normal and seborrhoeic shih tzu dogs.

Epidermal structure created by canine hair follicle keratinocytes enriched with bulge cells in a three-dimensional skin equivalent model in vitro: implications for regenerative therapy of canine epidermis.

Background: Keratinocytes in the hair follicle bulge region have a high proliferative capacity, with characteristics of epithelial stem cells. This cell population might thus be an ideal source for generating the interfollicular epidermis in a canine skin equivalent.

Hypothesis/objectives: This study was designed to determine the ability of canine hair follicle bulge cell-enriched keratinocytes to construct canine living skin equivalents with interfollicular epidermis in vitro.

Novel Therapy for Atherosclerosis Using Recombinant Immunotoxin Against Folate Receptor β-Expressing Macrophages.

Background: Folate receptor β (FRβ) is induced during macrophage activation. A recombinant immunotoxin consisting of the truncated Pseudomonas exotoxin A (PE38) conjugated to an anti-FRβ antibody (anti-FRβ-PE38) has been reported to kill activated macrophages in inflammatory diseases. To elucidate the effect of an immunotoxin targeting FRβ on atherosclerosis, we determined the presence of FRβ-expressing macrophages in atherosclerotic lesions and administered the FRβ immunotoxin in apolipoprotein E-deficient mice.

Loss of the protease dimerization inhibition activity of tipranavir (TPV) and its association with the acquisition of resistance to TPV by HIV-1.

Tipranavir (TPV), a protease inhibitor (PI) inhibiting the enzymatic activity and dimerization of HIV-1 protease, exerts potent activity against multi-PI-resistant HIV-1 isolates. When a mixture of 11 multi-PI-resistant (but TPV-sensitive) clinical isolates (HIV(11MIX)), which included HIV(B) and HIV(C), was selected against TPV, HIV(11MIX) rapidly (by 10 passages [HIV(11MIX)(P10)]) acquired high-level TPV resistance and replicated at high concentrations of TPV. HIV(11MIX)(P10) contained various amino acid substitutions, including I54V and V82T.

CYP90A1/CPD, a brassinosteroid biosynthetic cytochrome P450 of Arabidopsis, catalyzes C-3 oxidation.

Brassinosteroids (BRs) are steroidal phytohormones that regulate plant growth and development. Whereas in Arabidopsis the network-like routes of BR biosynthesis have been elucidated in considerable detail, the roles of some of the biosynthetic enzymes and their participation in the different subpathways remained to be clarified. We investigated the function of the cytochrome P450 monooxygenase CYP90A1/CPD, which earlier had been proposed to act as a BR C-23 hydroxylase.

Cerebral palsy, neurogenic bladder, and outcomes of lifetime care.

Aim: To determine the prevalence of symptomatic neurogenic bladder (SNB) and social and functional variables in a large sample of people with cerebral palsy (CP).

Method: The medical records of 214 individuals (96 females, 118 males) with CP between the years 1990 and 2000 were retrospectively reviewed. Individuals with frequency, urgency, or incontinence were assigned Gross Motor Function Classification System levels and underwent cystometrogram/electromyelogram studies.

Controlling the bleeding of jejunal varices formed at the site of choledochojejunostomy: report of 2 cases and a review of the literature.

Hemorrhage from jejunal varices formed at the site of Roux-en-Y choledochojejunostomy is rather rare, and no guidelines have so far been established for its treatment. This report presents the cases of 2 patients with jejunal varices formed at the site of choledochojejunostomy that were treated using different methods. An obstruction of the extrahepatic portal vein resulted in massive gastrointestinal bleeding in both cases CASE 1: A 59-year-old male developed jejunal varices at the site of choledochojejunostomy.

Surgical treatment for portosystemic encephalopathy in patients with liver cirrhosis: Occlusion of portosystemic shunt in combination with splenectomy.

Aim:   Operative ligation of the portosystemic shunt may control hepatic encephalopathy effectively, but the subsequent increase in portal vein pressure (PVP) leads to high mortality. Splenectomy can decrease inflow into the portal system, resulting in decreased portal pressure.

Methods:   We retrospectively examined the effect of splenectomy in combination with shunt closure on portosystemic encephalopathy.

Incidental renal cell carcinoma presenting in a renal transplant recipient with autosomal dominant polycystic kidney disease: a case report.

Introduction: We report an instructive case of incidental renal cell carcinoma in a patient with autosomal dominant polycystic kidney disease who underwent simultaneous bilateral native nephrectomy and living donor renal transplantation.

Case Presentation: A 57-year-old Asian man with end-stage kidney disease due to autosomal dominant polycystic kidney disease received a living kidney graft from his brother. Because of recurrent infection, chronic pain and enlarged kidneys, he underwent a bilateral nephrectomy with concomitant renal transplantation.

Renal vein extension using an autologous renal vein in a living donor with double inferior vena cava: a case report.

Background: When the kidney from a living donor with a double inferior vena cava (IVC) is harvested for renal transplantation, the short length of the renal vein may eventually create a technical problem for graft implantation. Herein, we have reported a rare case of renal vein extension using an autologous renal vein in a living donor with a double IVC.

Case Report: A 70-year-old man with end-stage renal disease owing to autosomal-dominant polycystic kidney disease underwent a living donor kidney graft from his wife who had a double IVC.

Safety and feasibility of diet-treated donors with steatotic livers at the initial consultation for living-donor liver transplantation.

Background: The purpose of this study was to evaluate both safety of diet-treated donors and the feasibility of their use for living-donor liver transplantation (LDLT).

Methods: A total of 128 living donors were enrolled in this study between April 2003 and March 2010. Of them, 41 were diagnosed with hepatic steatosis at the initial consultation.

Effect of switching from salmeterol/fluticasone to formoterol/ budesonide combinations in patients with uncontrolled asthma.

Background: Combination therapy with an inhaled corticosteroid (ICS) and a long-acting β(2)-agonist (LABA) in a single inhaler is the mainstay of asthma management and salmeterol/fluticasone combination (SFC) and fixed-dose formoterol/budesonide combination (FBC) are currently available in Japan; however, there is nothing to choose between the two. The purpose of this study was to clarify the effect of switching from SFC to FBC in patients with asthma not adequately controlled under the former treatment regimen.

Methods: This was a prospective, multicenter, open-label, uncontrolled longitudinal study in 87 adult patients with an Asthma Control Questionnaire, 5-item version (ACQ5) score of greater than 0.

Complex vascular reconstruction using donor's vessel grafts in orthotopic liver transplantation.

The vascular abnormalities of recipients are associated with reconstructive difficulties with an increased risk of postoperative complications. We performed an orthotopic liver transplantation that required a complex vascular reconstruction using donor vascular grafts. A patient with hepatitis B virus cirrhosis received a liver from a brain-dead donor.

Optimization of immunosuppressive therapy based on a multiparametric mixed lymphocyte reaction assay reduces infectious complications and mortality in living donor liver transplant recipients.

Aim: We investigated the clinical relevance of immune monitoring by a multiparametric mixed lymphocyte reaction (MLR) assay, wherein the number and phenotype of alloreactive precursors can be quantified by combining the results of carboxyfluorescein diacetate succinimidyl ester labeling and flow cytometry analysis.

Methods: In 51 adult patients undergoing living donor liver transplantation (OLT), immunosuppressive drugs were dosed on the basis of immune monitoring by the MLR assay (optimized protocol: group O). In 64 other patients, the agents were prescribed according to empirical regimens (empirical protocol: group E).

Therapeutic effect of Yokukansan on social isolation-induced aggressive behavior of zinc-deficient and pair-fed mice.

In patients with dementia including Alzheimer's disease, hallucinations, agitation/aggression and irritability are known to frequently occur and as distressing behavioral and psychological symptoms of dementia (BPSD). On the basis of the evidence on clinical efficacy and safety of Yokukansan, a traditional Japanese herbal medicine, on BPSD, in the present study, Yokukansan was examined in the therapeutic effects on social isolation-induced aggressive behavior of zinc-deficient and pair-fed mice. Yokukansan was p.

Systematic changes in the perceived posture of the wrist and elbow during formation of a phantom hand and arm.

Our previous study showed that a fully flexed or extended hand became perceived as an extended or flexed 'phantom' hand as ischemic anesthesia progressed (Inui et al. in J Physiol 589:5775-5784, 2011). Here, we examined what happened if the hand was held in the midposition before and during the anesthesia.

Involvement of glucocorticoid-mediated Zn2+ signaling in attenuation of hippocampal CA1 LTP by acute stress.

Glucocorticoid-glutamatergic interactions have been proposed as a potential model to explain stress-mediated impairment of cognition. However, it is unknown whether glucocorticoid-zincergic interactions are involved in this impairment. Histochemically reactive zinc (Zn(2+)) is co-released with glutamate from zincergic neurons.

Effects of estrogen and progesterone on cerebrovascular responses to euoxic hypercapnia in women.

Objectives: To determine the cerebral blood flow response to step changes in end-tidal Pco(2) in premenopausal women (n = 10; mean age±standard deviation 27.0±6.4 years) during the follicular (FP), mid-cycle (MC) and luteal (LP) phases of the menstrual cycle.

Gene transcription analysis in lesional skin of canine epitheliotropic cutaneous lymphoma using quantitative real-time RT-PCR.

Canine epitheliotropic cutaneous lymphoma (cECL) is characterized by infiltration of neoplastic lymphocytes in the skin with a specific tropism for the epidermis. Migration of lymphocytes is strictly controlled by interactions between chemokines and chemokine receptors, which may be involved in the pathogenesis of cECL. In this study, we investigated mRNA transcription levels of several chemokines (CCL17, CCL19, CCL21, CCL22, CCL27, CCL28 and CXCL10) and chemokine receptors (CCR4, CCR7, CCR10 and CXCR3) in lesional skin of cECL by quantitative real-time RT-PCR.
