High-fat diet during pregnancy lowers fetal weight and has a long-lasting adverse effect on brown adipose tissue in the offspring.

Maternal obesity and malnutrition during gestation and lactation have been recognized to increase the risk of obesity and metabolic disorders in the offspring across their lifespan. However, the gestational period during which malnutrition exerts a decisive effect is unclear. Brown adipose tissue (BAT) plays a critical role in energy metabolism owing to its high efficiency in oxidizing glucose and fatty acids.

A Case of Infantile Alagille Syndrome With Severe Dyslipidemia: New Insight into Lipid Metabolism and Therapeutics.

Alagille syndrome (AGS) is an autosomal dominant genetic disorder characterized by congenital heart disease, hepatic cholestasis, dyslipidemia, and characteristic facies since infancy. Cholestatic hypercholesterolemia in patients diagnosed with AGS is occasionally refractory and resistant to conventional treatments. We report the case of a 4-month-old boy diagnosed with AGS and refractory dyslipidemia due to cholestatic liver disease.

ACE2 exerts anti-obesity effect via stimulating brown adipose tissue and induction of browning in white adipose tissue.

The angiotensin II (ANG II)-ANG II type 1 receptor (ATR) axis is a key player in the pathophysiology of obesity. Angiotensin-converting enzyme 2 (ACE2) counteracts the ANG II/ATR axis via converting ANG II to angiotensin 1-7 (Ang 1-7), which is known to have an anti-obesity effect. In this study, we hypothesized that ACE2 exerts a strong anti-obesity effect by increasing Ang 1-7 levels.

High-fat diet accelerates extreme obesity with hyperphagia in female heterozygous Mecp2-null mice.

Rett syndrome (RTT) is an X-linked neurodevelopmental disorder caused by mutation of the methyl-CpG-binding protein 2 (MECP2) gene. Although RTT has been associated with obesity, the underlying mechanism has not yet been elucidated. In this study, female heterozygous Mecp2-null mice (Mecp2+/- mice), a model of RTT, were fed a normal chow diet or high-fat diet (HFD), and the changes in molecular signaling pathways were investigated.

Erythropoietin and long-acting erythropoiesis stimulating agent ameliorate non-alcoholic fatty liver disease by increasing lipolysis and decreasing lipogenesis via EPOR/STAT pathway.

Erythropoietin (EPO) has been reported to exert a beneficial effect on glucose metabolism in obesity. However, the effect of EPO on lipid metabolism and non-alcoholic fatty liver disease (NAFLD) was unclear. Furthermore, the effect of long acting erythropoiesis stimulating agents (ESA) on metabolism has not been poorly understood.

Angiotensin 1-7 stimulates brown adipose tissue and reduces diet-induced obesity.

The renin-angiotensin system is a key regulator of metabolism with beneficial effects of the angiotensin 1-7 (Ang 1-7) peptide. We hypothesized that the antiobesity effect of Ang 1-7 was related to the stimulation of brown adipose tissue (BAT). We administered Ang 1-7 (0.

Neoadjuvant Treatment With Cyclooxygenase-2 Inhibitor and Prednisolone Allows Conservative Surgery for Inflammatory Myofibroblastic Tumor of the Bladder.

Inflammatory myofibroblastic tumor (IMT), which expresses cyclooxygenase-2 (COX-2), can be effectively treated with COX-2 inhibitor. Here, we report a case of urinary bladder IMT in a 13-year-old boy. Although total cystectomy was initially planned for complete resection of the tumor, neoadjuvant treatment with COX-2 inhibitor and prednisolone reduced the size of the tumor and enabled complete resection of the tumor by partial cystectomy.

Sorafenib Therapy for Pediatric Acute Myeloid Leukemia with FMS-like Tyrosine Kinase 3-internal Tandem Duplication Mutations: 2 Case Reports.

Sorafenib is a promising agent for treating pediatric refractory acute myeloid leukemia (AML) exhibiting FMS-like tyrosine kinase 3-internal tandem duplication (FLT3-ITD); however, its optimal use needs to be established. We report 2 cases of refractory pediatric FLT3-ITD-positive AML treated with sorafenib. Case 1 underwent stem cell transplantation (SCT) without entering remission, despite the use of chemotherapy.

FN1: a novel fusion partner of ALK in an inflammatory myofibroblastic tumor.

Inflammatory myofibroblastic tumors (IMTs) are rare tumors characterized as low-to-intermediate grade sarcomas. Rearrangements of the anaplastic lymphoma kinase (ALK) gene have been reported in IMT. Here, we describe a novel fusion gene in an IMT tumor specimen.

Successful treatment of idiopathic colitis related to XIAP deficiency with allo-HSCT using reduced-intensity conditioning.

Recently, it has been reported that Crohn's-like intractable colitis occurred in approximately 20% of the patients with XIAP deficiency, also known as X-linked lymphoproliferative disease type 2. Because treatment used for Crohn's disease is not always effective for Crohn's-like colitis related to XIAP deficiency, more effective treatment should be established. Although several studies reported allo-HSCT might be promising even for Crohn's-like colitis related to XIAP deficiency, the outcome of allo-HSCT using MAC for XIAP deficiency is extremely poor due to frequent TRM.

MRD detection of leukemia relapse using HLA typing by FACS in combination with FISH after mismatched allogeneic stem cell transplantation.

Loss of mismatched HLA is a cause of relapse following HLA-mismatched allo-SCT. We directly detected the loss of mismatched HLA alleles in relapsed leukemic cells at a MRD level using HLA typing by multicolor FACS (HLA-Flow) in combination with FISH in the BM of two patients with MLL-AF9-positive AML, at 6 and 10 months after mismatched allo-SCT. HLA-Flow with FISH analysis detected relapsed leukemic cells not expressing a mismatched HLA allele and harboring the MLL rearrangement.

Effect of a single inhalation of laninamivir octanoate in children with influenza.

Objective: The purpose of this study was to compare the efficiency and safety of a new neuraminidase inhibitor, laninamivir octanoate (LO), with zanamivir (ZN) in pediatric patients with influenza.

Methods: One hundred twelve pediatric patients ≤ 15 years, diagnosed with a rapid diagnostic test as having influenza from January to May 2011, were randomly assigned to the LO group or the ZN group, and their parents were asked to complete a questionnaire during the recovery at home. The LO group was instructed to inhale LO once (20 or 40 mg depending on age), and the ZN group was instructed to inhale ZN (20 mg) twice daily for 5 days.
