INTRODUCTION: Individually, neurometabolic diseases are ultra rare, but for some of them there is an effective treatment. DEVELOPMENT: Several recent therapeutic advances are reviewed. Today, the possibilities of treatment for lysosomal diseases have improved. In recent years the use of enzyme replacement therapy has become more widely extended to treat mucopolysaccharidosis type IVA (Morquio A), mucopolysaccharidosis type VII (Sly syndrome), lysosomal acid lipase deficiency and alpha-mannosidosis...

Microbial enrichments cultures are a useful strategy to speed up the search for enzymes that can be employed in industrial processes. Lipases have gained special attention because they show unique properties such as: broad substrate specificity, enantio- and regio-selectivity and stability in organic solvents. A major goal is to identify novel lipolytic enzymes from microorganisms living in cold extreme environments such as high Andean soils, of relevance to our study being their capability be used in industrial processes...

Determining optimum stocking density of the white shrimp Litopenaeus vannamei (Boone) is a big concern for shrimp farmers. However, few studies have assessed the influence of stocking density on the antioxidant status, immunology, digestive enzyme activities, and growth performance of white shrimp in biofloc systems. In this study, these parameters of white shrimp in a biofloc system were compared at three stocking densities: 300 orgs m(-3) as low stocking density (LD), 400 orgs m(-3) as medium stocking density (MD), and 500 orgs m(-3) as high stocking density (HD)...

A sulphated polysaccharide from brown algae Sargassum vulgare (SVSP) was extracted and examined with respect to chemical, structural characterization and hypolipidemic effects. SVSP consisted mainly of sulphate and total sugars with low levels of lipids and proteins. Its structure was studied by nuclear magnetic resonance (RMN), gas chromatography-mass spectrometry (GC-MS), infra-red spectroscopic, differential scanning calorimetry and X-ray diffraction analysis. Allowing us therefore to revealed that SVSP was composed of glucose, rhamnose, xylose, galactose, mannose and arabinose with XRD pattern that was typical for a semi-crystalline polymer and complexities of the spectra reflected its homogeneous structure...

Severe hypertriglyceridemia is defined at a plasma triglyceride (TG) concentration of >885 mg/dl and may result - in particular when clinical symptoms appear before the age of 40 - from "large variant" mutations in genes which influence the function of the lipoprotein lipase (LPL). For diagnosis, secondary factors have to be excluded and treated before further genetic tests are considered. Typical symptoms in almost all patients are recurrent, sometimes severe abdominal pain attacks, which can result in acute pancreatitis, the most important, sometimes life-threatening complication...

Transhiatal herniation of the pancreas is rare. Acute pancreatitis secondary to this phenomenon is particularly unusual. A 102-year-old woman presented with 1 day of severe chest pain, vomiting, dyspnea, and diaphoresis. Serum lipase was elevated, and computed tomography angiogram of the chest and magnetic resonance cholangiopancreatography revealed a hiatal hernia containing the pancreas, with associated findings of pancreatitis. Pancreatitis in this setting may be due to repetitive trauma or ischemia from sliding, intermittent folding of the pancreatic duct, or pancreatic incarceration...

In liver steatosis i.e., fatty liver), hepatocytes accumulate many large neutral lipid-storage organelles known as lipid droplets (LDs). LDs are important in the maintenance of energy homeostasis, but the signaling mechanisms that stimulate LD metabolism in hepatocytes are poorly defined. In adipocytes, catecholamines target the β-adrenergic (β-AR)/cAMP pathway to activate cytosolic lipases and induce their recruitment to the LD surface. Therefore, the goal of this study was to determine whether hepatocytes, like adipocytes, also undergo cAMP-mediated lipolysis in response to β-AR stimulation...

Mycobacterium tuberculosis causes tuberculosis in humans and predominantly infects alveolar macrophages. To survive inside host lesions and to evade immune surveillance, this pathogen has developed many strategies. For example, M. tuberculosis uses host-derived lipids/fatty acids as nutrients for prolonged persistence within hypoxic host microenvironments. M. tuberculosis imports these metabolites through its respective transporters, and in the case of host fatty acids, a pertinent question arises: does M. tuberculosis have the enzyme(s) for cleavage of fatty acids from host lipids? We show herein that a previously uncharacterized membrane-associated M...

Due to the high content of bioactive compounds, herbal teas are being investigated as adjuvant in chronic disease management. Studies have shown that mango leaf tea contain mangiferin, total phenolics and antioxidants, compounds with many functional properties. Therefore, this study aims to evaluate the anti-obesity effects of tea from Mangifera indica L. leaves, Ubá variety (TML), in obese rats fed a high-fat diet (HFD). For this, adult male Wistar rats were divided into three groups (n=8): the control group (fed AIN-93 diet), obese group (fed a HFD) and treated group (fed a HFD and supplemented with TML for 8 weeks)...

Peiyi Shen, Yiren Yue, Kee-Hong Kim, Yeonhwa Park
Excess fat accumulation and abnormal metabolism are involved in numerous diseases and thus the research on identification of compounds that can regulate energy homeostasis could significantly facilitate the current effort to prevent and/or treat metabolic disorders. Piceatannol, one of the natural stilbenes, was previously found to decrease lipid accumulation of 3T3-L1 adipocytes. However, its role in fat metabolism in vivo is not known. Thus, Caenorhabditis elegans as an animal model was used in the current study to determine the effect of piceatannol on fat accumulation and its underlying mechanisms...

Isoquercitrin, (IQ, quercetin-3-O-β-d-glucopyranoside) is known for strong chemoprotectant activities. Acylation of flavonoid glucosides with carboxylic acids containing an aromatic ring brings entirely new properties to these compounds. Here, we describe the chemical and enzymatic synthesis of a series of IQ derivatives at the C-6″. IQ benzoate, phenylacetate, phenylpropanoate and cinnamate were prepared from respective vinyl esters using Novozym 435 (Lipase B from Candida antarctica immobilized on acrylic resin)...

Thrombotic microangiopathy (TMA) occurring after acute pancreatitis is rarely described. Without prompt intervention, TMA can be, and often is, lethal, so prompt recognition is important. Here, we present a case of a 61-year-old woman with a history of alcohol misuse who presented with epigastric pain, nausea and vomiting after binge drinking. Elevated serum lipase and imaging were suggestive of acute-on-chronic pancreatitis. Although the patient's symptoms of acute pancreatitis subsided, her anaemia, thrombocytopenia and acute kidney injury worsened...

STUDY QUESTION: Does the deletion of adipose triglyceride lipase (Atgl) gene impair male fertility? SUMMARY ANSWER: The deletion of Atgl gene impaired male fertility but the effect was partially reversed by a low long chain triglyceride (TG) diet. WHAT IS KNOWN ALREADY: ATGL specifically hydrolyses long-chain fatty acid triglyceride (TG) to diacylglycerol and a high level of expression of ATGL in testes has been reported. However, the role of ATGL in male fertility is unknown...

Recently the Centrifugal Partition Chromatography (CPC) device is investigated as a reactor for biocatalytic reactions, as it enables biocatalyst immobilization without solid support and continuous operation of biphasic reaction systems. However, a detailed determination of the enzymes behavior in the CPC reactor and comparison to a classical stirred tank reactor (STR) for biphasic enzyme catalysis is not shown yet. In this study, the performance of an enzymatic biphasic hydrolysis reaction using lipase from Candida rugosa is systematically evaluated using a STR...

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...

An improved method based on the p-nitrophenyl long chain esters method is proposed for measuring lipase hydrolytic activity in aqueous media. Using ethylene glycol as co-solvent for hydrophobic p-nitrophenyl substrates in aqueous buffer, lipase activity is measured by following the release of p-nitrophenol. This fast and easy to handle method improves the solubility of both substrate and product, and also the stability of the substrate. It avoids the use of solvents such as ethanol or propanol, permits the comparison of all the p-nitrophenol acyl ester substrates and allows the influence of ions like Ca(+2) to be studied, while avoiding turbidity in the reaction medium...

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...
