The purpose of the present study was to investigate the effect of Luteolin(Lut) on myocardial ischemia reperfusion injury and explore the underlying mechanism. Myocardial ischemia reperfusion injury (I/R) model was induced with 30min of left anterior descending (LAD) occlusion followed by 24h of reperfusion. In vivo, the rats were randomly divided into 5 groups: (1)Sham, (2)I/R, (3)I/R+Lut(40mg/kg), (4)I/R+Lut(80mg/kg) and (5)I/R+Lut(160mg/kg). In vitro, the H9c2 cells were assigned to five groups: (1)control, (2)hypoxia-reoxygenation(H/R), (3)H/R+Lut(5μM), (4)H/R+Lut(10μM) and (5)H/R+Lut(20μM)...

Here, a new metabolic pathway for the production of 5-aminovalerate (5AVA) from l-lysine via cadaverine as intermediate was established and this three-step-pathway comprises l-lysine decarboxylase (LdcC), putrescine transaminase (PatA) and γ-aminobutyraldehyde dehydrogenase (PatD). Since Corynebacterium glutamicum is used for industrial l-lysine production, the pathway was established in this bacterium. Upon expression of ldcC, patA and patD from Escherichia coli in C. glutamicum wild type, production 5AVA was achieved...

OBJECTIVES: Hepatic glutamic pyruvic transaminase (GPT; also known as alanine aminotransferase) is a gluconeogenesis enzyme that catalyzes conversions between alanine and pyruvic acid. It is also used as a blood biomarker for hepatic damage. In this study, we investigated whether insulin regulates GPT expression, as it does for other gluconeogenesis genes, and if this involves the epigenetic modification of histone acetylation. METHODS: Human liver-derived HepG2 cells were cultured with 0...

Background.: Adults with the tick-borne disease human granulocytic anaplasmosis (HGA) have a spectrum of acute febrile illnesses that, if untreated, might be severe. Clinical presentation and outcomes of children with HGA have been poorly described. Methods.: A retrospective analysis was conducted to determine the frequency, presentation, and outcomes of pediatric patients with HGA between 1994 and 2015 in a region of Wisconsin in which HGA is highly endemic. Patients with related International Classification of Diseases Ninth and Tenth Revision (ICD-9 and ICD-10, respectively) codes or positive HGA laboratory test results were evaluated and classified as having had confirmed, probable, or suspected HGA on the basis of the Centers for Disease Control and Prevention (CDC) case definition...

BACKGROUND: Micronutrient deficiencies are common among adults living with HIV disease, particularly in low-income settings where the diet may be low in essential vitamins and minerals. Some micronutrients play critical roles in maintenance of the immune system, and routine supplementation could therefore be beneficial. This is an update of a Cochrane Review previously published in 2010. OBJECTIVES: To assess whether micronutrient supplements are effective and safe in reducing mortality and HIV-related morbidity of HIV-positive adults (excluding pregnant women)...

Chiral amines are essential precursors in the production of biologically active compounds, including several important drugs. Among the biocatalytic strategies that have been developed for their synthesis, the use of ω-transaminases (ω-TA) appears as an attractive alternative allowing the stereoselective amination of prochiral ketones. However, the problems associated with narrow substrate specificity, unfavourable reaction equilibrium and expensive amine donors still hamper its industrial application. The search for novel enzymes from nature can contribute to expand the catalytic repertoire of ω-TA and help to circumvent some of these problems...

Various cell populations expressing NK1.1 contribute to innate host defense and systemic inflammatory responses, but their role in hemorrhagic shock and trauma remains uncertain. NK1.1(+) cells were depleted by i.p. administration of anti-NK1.1 (or isotype control) on two consecutive days, followed by hemorrhagic shock with resuscitation and peripheral tissue trauma (HS/T). The plasma levels of IL-6, MCP-1, alanine transaminase (ALT), and aspartate aminotransferase (AST) were measured at 6 and 24 h. Histology in liver and gut were examined at 6 and 24 h...

Atherosclerosis was previously thought to be a disease that primarily involves lipid accumulation in the arterial wall. In this report, we investigated the effect of Viola mandshurica W. Becker (V. mandshurica) water extract on atherosclerosis in apolipoprotein E deficient (ApoE[Formula: see text]) mice. The administration of V. mandshurica to high-fat diet-fed mice reduced body weight, liver weight, and serum levels of lipids (total cholesterol, low-density lipoprotein-cholesterol, triglycerides), glucose, alanine transaminase, and aspartate transaminase...

NAFLD is an important concern, as it can be identified in the majority of T2D persons and tracks with adverse outcome ((1,2) ). In the current issue of the Journal, Feng et al describe effects of liraglutide, gliclazide, and metformin in a well-characterized group of patients with poorly controlled type 2 diabetes (T2D) and nonalcoholic fatty liver disease (NAFLD), whose HbA1c levels decreased from 8.9 to 5.9%, from 9.0 to 6.5%, and from 9.4 to 6.0%, respectively ((3) ). Intrahepatic fat decreased from baseline levels around 35% in all groups, by approximately 60% with liraglutide, significantly more than the decrease of approximately 30% with gliclazide, and the reduction in transaminase levels was only significant with liraglutide and with metformin...

Common side effects of clofarabine (CFB) are liver toxicity, particularly a transient elevation of transaminases and skin toxicity. We studied the correlation of pharmacokinetic (PK) parameters with these toxicities and the efficacy of CFB in patients with relapsed or refractory acute myeloid leukemia. Clofarabine PK parameters showed large inter-individual variability. A higher CFB area under the curve was significantly associated with higher transaminase levels (p = .011 for aspartate aminotransferase (AST), adjusted for age, sex, cumulated CFB dosage, baseline AST, and glomerular filtration rate (GFR))...

Non-alcoholic fatty liver disease (NAFLD) may be a cause of hepatocellular carcinoma (HCC), but its high prevalence challenges current surveillance strategies. We aimed to evaluate HCC incidences in different risk stratifications for non-cirrhotic NAFLD. Using Taiwan's National Health Insurance Research Database, we located 31,571 patients with NAFLD between the years 1998 and 2012. After excluding other causes of hepatitis, underlying cirrhosis, or malignancy, 18,080 patients were recruited for final analysis...

Lysosomal acid lipase deficiency (LAL-D) is still a little recognized genetic disease with significant morbidity and mortality in children and adults. This document provides guidance on when to suspect LAL-D and how to diagnose it. It is recommended to add lysosomal acid lipase deficiency to the List of differential diagnoses of sepsis, oncological diseases, storage diseases, persistent diarrhea, chronic malnutrition, and hemophagocytic lymphohistiocytosis. It should also be considered in young patients with dyslipidemia and atherosclerosis as well as diseases associated with fatty liver and/or hepatomegaly...

We present 4 normal-weight sibling children with lysosomal acid lipase deficiency (LAL-D). LAL-D was considered in the differential diagnosis based on the absence of secondary causes and primary inherited traits for their marked hyperlipidemia, together with unexplained hepatic transaminase elevation. Residual lysosomal acid lipase activity confirmed the diagnosis. DNA sequencing of LIPA indicated that the siblings were compound heterozygotes (c.894G>A and c.428+1G>A). This case describes the unusual occurrence of all offspring from the same nonconsanguineous mother and father inheriting compound heterozygosity of a recessive trait and the identification of an apparently unique LIPA mutation (c...
