PURPOSE: Dicer, an RNase III type endonuclease, is a key enzyme involved in miRNA biogenesis. It has been shown that this enzyme is essential for several aspects of postnatal kidney functions and homeostasis. In this study, we have examined conditional knockout (cKO) mice for Dicer in Pax8 (Paired-box gene 8) expressing cells to investigate the kidney protein profile. This specific model develops a glomerulocystic phenotype coupled with urinary concentration impairment, proteinuria and severe renal failure...

Decreased high-density lipoprotein (HDL) particle size, cholesterol poor, apolipoprotein A-I-rich HDL particles leading to smaller HDL particle size, may be associated with an anti-atherosclerotic effect. The data are sparse regarding the relationship between n-3 polyunsaturated fatty acids [n-3 PUFAs: eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA)] and HDL particle size. This study was designed as a hospital-based cross-sectional study to investigate the relationship between the serum levels of n-3 PUFAs and the HDL-cholesterol/apolipoprotein A-1 ratio, as estimated by the HDL particle size, in patients with the presence of one or more risk factors for atherosclerotic cardiovascular disease (ASCVD)...

BACKGROUND: A wide range of molecules are used by tapeworm metacestodes to establish successful infection in the hostile environment of the host. Reports indicating the proteins in the cestode-host interactions are limited predominantly to taeniids, with no previous data available for non-taeniid species. A non-taeniid, Hymenolepis diminuta, represents one of the most important model species in cestode biology and exhibits an exceptional developmental plasticity in its life-cycle, which involves two phylogenetically distant hosts, arthropod and vertebrate...

BACKGROUND: The nematode Trichinella pseudospiralis is an intracellular parasite of mammalian skeletal muscle cells and exists in a non-encapsulated form. Previous studies demonstrated that T. pseudospiralis could induce a lower host inflammatory response. Excretory-secretory (ES) proteins as the most important products of host-parasite interaction may play the main functional role in alleviating host inflammation. However, the ES products of T. pseudospiralis early stage are still unknown...

PURPOSE: Technetium-99m is a radioactive tracer that emits gamma rays. Its half-life time is 6 hours. Similar to other ionizing radiations, the main mechanism of radiation-induced effects is initiated through the production of Reactive Oxygen Species (ROS). The present study was designed to determine the possible protective effects of Ginkgo-Biloba and Angelica-Archangelica against oxidative organ damage that was induced by (99m)Tc-sestamibi. MATERIALS AND METHODS: The experiments were performed on thirty-six Wistar-rats which were subdivided into control groups and groups exposed to (99m)Tc-sestamibi...

Plant cell wall polysaccharides are notoriously difficult to analyze, and most methods require expensive equipment, skilled operators, and large amounts of purified material. Here, we describe a simple method for gaining detailed polysaccharide structural information, including resolution of structural isomers. For polysaccharide analysis by gel electrophoresis (PACE), plant cell wall material is hydrolyzed with glycosyl hydrolases specific to the polysaccharide of interest (e.g., mannanases for mannan). Large format polyacrylamide gels are then used to separate the released oligosaccharides, which have been fluorescently labeled...

We previously identified the aur1 gene cluster, responsible for the production of the angucycline antibiotic auricin in Streptomyces aureofaciens CCM 3239. Pulse-field gel electrophoresis showed a single, 241kb linear plasmid, pSA3239, in this strain, and several approaches confirmed the presence of the aur1 cluster in this plasmid. We report here the nucleotide sequence of this 241,076-bp plasmid. pSA3239 contains an unprecedentedly small (13bp) telomeric sequence CCCGCGGAGCGGG, which is identical to the conserved Palindrome I sequence involved in the priming of end-patching replication...

AIMS: Previous studies demonstrated a remarkable increase of urinary InsP6 by topical administration. However, the methodology used for InsP6 analysis was not specific. The aim of this paper is to measure urinary inositol phosphates InsPs using more advanced methodologies and to compare the results with those obtained by the non-specific method. MATERIALS AND METHODS: We fed 12 female rats with a diet without InsP6 for 16days. Then, we administered a topical InsP6 gel at high doses for 7days (50mgInsP6/day) or at low doses for 28days (20mgInsP6/day)...

Lizards are seasonal breeders. Cyclic reproductive nature makes lizard as a useful model for the study of the reproductively active protein secretions in the epididymis. During breeding season, the epididymides of the lizard secret proteins that mixes with the spermatozoa and create a favourable environment for sperm maturation. In this spectrum, the aim of this study is to identify and characterize proteins which are present in the lumen of the epididymis of the lizard, E. carinata during the active phase of reproduction...

PEGylation is one of the strategies used for enhancing in vivo residence time of recombinant human Granulocyte Colony-Stimulating Factor (rhG-CSF) and therefore reducing in dose frequency to better fit with patient comfort treatment. In this study, three methoxy polyethylene glycol propionaldehydes (mPEG- ALD) of 10, 20 and 30kDa MW were utilized to produce biologically active monoPEGylated rhG-CSF with enhanced molecular weight. PEGylation reactions were carried out at room temperature and pH 5.0 in the presence of cyanoborohydride and two mPEG-ALD: protein molar ratios (3:1 and 5:1)...

Studies have suggested that the phenomenon of dark cutting (Canada B4) beef may also be related to muscle glycolytic proteins. The objective of this study, therefore, was to analyze longissimus thoracis (LT; n=23), from Canada AA (n=8), atypical (AB4; pH<5.9, n=8) and typical (TB4; pH>5.9, n=7) B4 heifer and steer carcasses, for sarcoplasmic and myofibrillar proteins using 2-D gel electrophoresis and LC-MS/MS mass spectrometry. Results indicated that AB4 LT had intramuscular pH and lactate concentration similar to Canada AA but lower (P<0...

BACKGROUND: Some iodinated radio-contrast media absorb UV light and can therefore be detected by capillary zone electrophoresis (CZE). If seen, these peaks are typically small with "quantifications" of below 5g/L. Here we describe detection of a large peak on CZE that was due to the radio-contrast agent, Omnipaque(T)(M). METHODS: Serum from a patient was analysed by CZE, and the IgG, IgA, IgM and total protein concentrations were measured. The serum sample was further analysed by gel electrophoresis and immunofixation...

REVIEW
Carla Oliveira, Lucília Domingues
The final goal in recombinant protein production is to obtain high-quality pure protein samples. Indeed, the successful downstream application of a recombinant protein depends on its quality. Besides production, which is conditioned by the host, the quality of a recombinant protein product relies mainly on the purification procedure. Thus, the purification strategy must be carefully designed from the molecular level. On the other hand, the quality control of a protein sample must be performed to ensure its purity, homogeneity and structural conformity, in order to validate the recombinant production and purification process...

Vibrio parahaemolyticus (Vp) and Vibrio vulnificus (Vv) are naturally occurring estuarine bacteria and are the leading causes of seafood-associated infections and mortality in the USA. Though multiple-antibiotic resistant Vp and Vv have been reported resistance patterns in vibrios are not as well documented as other food-borne bacterial pathogens. Salinity relaying (SR) is a Post-Harvest Processing (PHP) treatment to reduce the abundance of these pathogens in shellfish harvested during the warmer months. The purpose of this study was to evaluate the antimicrobial susceptibility (AMS), pathogenicity and genetic profiles of Vp and Vv recovered from oysters during an oyster relay study...
