Hydroethanolic Extract of Morus nigra L. Leaves: A Dual PPAR-α/γ Agonist with Anti-Inflammatory Properties in Lipopolysaccharide-Stimulated RAW 264.7.

Inhibition of systemic inflammation has been a beneficial strategy in treating several non-communicable diseases, which represent one of the major causes of mortality in the world. The Peroxisome Proliferator-Activated Receptors (PPAR) are interesting pharmacological targets, since they can act both through the metabolic and anti-inflammatory pathways. L.

Sequencing and characterization of an L-asparaginase gene from a new species of Penicillium section Citrina isolated from Cerrado.

The enzyme L-asparaginase (L-ASNase) is used in the treatment of Acute Lymphoblastic Leukemia. The preparations of this enzyme for clinical use are derived from bacterial sources and its use is associated with serious adverse reactions. In this context, it is important to find new sources of L-ASNase.

Transcriptomic studies on Purpureocillium lilacinum reveal molecular mechanisms of response to fluconazole and itraconazole.

Filamentous fungus Purpureocillium lilacinum is an emerging pathogen that infects immunocompromised and immunocompetent individuals and is resistant to several azole molecules. Although azole resistance mechanisms are well studied in Aspergillus sp. and Candida sp.

Optimization of aqueous two-phase micellar system for partial purification of L-asparaginase from Penicillium sp. grown in wheat bran as agro-industrial residue.

L-asparaginase has been used in the remission of malignant neoplasms such as acute lymphoblastic leukemia. The search for new sources of this enzyme has become attractive for therapeutics. Traditional methods for biomolecule purification involve several steps.

Interferences that impact measuring optimal L-asparaginase activity and consequent errors interpreting these data.

L-asparaginase is an enzyme produced by microorganisms, plants, and animals, which is used clinically for the treatment for acute lymphoblastic leukemia (ALL) and, in the food industry, to control acrylamide formation in baked foods. The purpose of this review was to evaluate the available literature regarding microbial sources of L-asparaginase, culture media used to achieve maximum enzyme expression in microbial fermentations, and assay methods employed to assess L-asparaginase activity. Studies were gathered by searching PubMed, and Web of Science databases before January 22, 2018, with no time restrictions.

Optimization of Xylanase Production from in Soybean Residue.

Enzymatic hydrolysis is an important but expensive step in the process to obtain enzyme derived products. Thus, the production of efficient enzymes is of great interest for this biotechnological application. The production of xylanase by in soybean residues was optimized using 2 × 2 factorial designs.

Optimization and purification of l-asparaginase from fungi: A systematic review.

The purpose of this systematic review was to identify the available literature of the l-asparaginase producing fungi. This study followed the Preferred Reporting Items for Systematic Reviews. The search was conducted on five databases: LILACS, PubMed, Science Direct, Scopus and Web of Science up until July 20th, 2016, with no time or language restrictions.

Neurological manifestations of congenital Zika virus infection.

Introduction: In 2015, it was observed a rise in the number of microcephalic newborns associated with a history of non-specific febrile sickness and rash during pregnancy in Brazil. Since then, microcephaly has emerged as a public health concern. A few months after, the causal relation between congenital microcephaly and the Zika virus was discovered.

Extracts of Morus nigra L. Leaves Standardized in Chlorogenic Acid, Rutin and Isoquercitrin: Tyrosinase Inhibition and Cytotoxicity.

Melanogenesis is a process responsible for melanin production, which is stored in melanocytes containing tyrosinase. Inhibition of this enzyme is a target in the cosmetics industry, since it controls undesirable skin conditions such as hyperpigmentation due to the overproduction of melanin. Species of the Morus genus are known for the beneficial uses offered in different parts of its plants, including tyrosinase inhibition.

A biotechnology perspective of fungal proteases.

Proteases hydrolyze the peptide bonds of proteins into peptides and amino acids, being found in all living organisms, and are essential for cell growth and differentiation. Proteolytic enzymes have potential application in a wide number of industrial processes such as food, laundry detergent and pharmaceutical. Proteases from microbial sources have dominated applications in industrial sectors.

Significant differences in integration sites of Moloney murine leukemia virus/Moloney murine sarcoma virus retroviral vector carrying recombinant coagulation factor IX in two human cell lines.

Ligation-mediated-PCR was performed followed by the mapping of 177 and 150 integration sites from HepG2 and Hek293 transduced with chimera vector carrying recombinant human Factor IX (rhFIX) cDNA, respectively. The sequences were analyzed for chromosome preference, CpG, transcription start site (TSS), repetitive elements, fragile sites and target genes. In HepG2, rhFIX was had an increased preference for chromosomes 6 and 17; the median distance to the nearest CpG islands was 15,240 base pairs and 37 % of the integrations occurred in RefSeq genes.

Recombinant glycoprotein production in human cell lines.

The most important properties of a protein are determined by its primary structure, its amino acid sequence. However, protein features can be also modified by a large number of posttranslational modifications. These modifications can occur during or after the synthesis process, and glycosylation appears as the most common posttranslational modification.

Patents in therapeutic recombinant protein production using mammalian cells.

The industrial production of recombinant proteins preferentially requires the generation of stable cell lines expressing proteins in a quick, relatively facile, and a reproducible manner. Different methods are used to insert exogenous DNA into the host cell, and choosing the appropriate producing cell is of paramount importance for the efficient production and quality of the recombinant protein. This review addresses the advances in recombinant protein production in mammalian cell lines, according to key patents from the last 30 years.

Isolated superficial peroneal nerve lesion in pure neural leprosy: case report.

Patients with leprosy may have only nerve involvement without skin changes. These cases are known as pure neural leprosy and can be seen in 10% of leprosy patients. Most patients have mononeuritic or multiple mononeuritic neuropathy patterns.
