13. Mechanistic effect of the human GJB6 gene and its mutations in HaCaT cell proliferation and apoptosis
We constructed lentiviral vectors containing the human wild-type GJB6 gene and the mutant variants A88V and G11R. The three proteins were stably expressed by the Tet-on system in the HaCaT cell line and used to study the functional effect of the variants. The CCK-8 assay and flow cytometric analyses were used to determine the levels of cell proliferation and

14. Modulation of the prostaglandin-endoperoxide synthase 2 gene expression by variant haplotypes: influence of the 3′-untranslated region
The inducible inflammatory enzyme cycloxigenase-2 is up-regulated in cancer, and favors tumor progression. Cycloxigenase-2 is encoded by the prostaglandin-endoperoxide synthase 2 (PTGS2) gene, which presents sequence variations in the promoter region (PR) and in the 3′-untranslated region (3′-UTR). Different PR (rs689465, rs689466, rs20417) and 3′-UTR

15. Effect of ultrasound streaming on the disinfection of flattened root canals prepared by rotary and reciprocating systems
Abstract New technical and scientific developments have been advocated to promote the success of the endodontic treatment. In addition to rotary and reciprocating systems, irrigating solution agitation has been suggested and passive ultrasonic irrigation (PUI) is the most used. Objective: To evaluate, in vitro, the effect of ultrasound streaming (US) in the

16. MICROEMULSION OF BRAZIL NUT OIL AS A NATURAL PRODUCT TO IMPROVE SUPEROXIDE RELEASE IN HUMAN PHAGOCYTES
The aim of this study was to develop and characterize a Brazil nut oil microemulsion system and determine the effect of this microemulsion on the superoxide release in human phagocytes. The microemulsion was formulated using distilled water, Brazil nut as the oily phase, Sorbitan monooleate, Polysorbate 80, and butan-1-ol. Hydrophile-lipophile balance of Bra

18. Bioactive compounds and antioxidant activity analysis during orange vinegar production
Abstract Citrus fruits are significant sources of bioactive compounds, such as ascorbic acid, polyphenols and carotenoids, due to their antioxidant properties important for human nutrition. In addition, since oranges possess high sugar content (8-15%), making vinegars from alcoholic orange substrates, with functional characteristics is a possible development

19. Actividad de enzimas del estrés oxidativo en plantas de tomate cv. Amalia en respuesta al plomo
ABSTRACT Contamination of soils by heavy metals is a result of human activity, agriculture and industry. Among heavy metals, lead is a potential pollutant that in plants causes numerous symptoms of toxicity such as stunted growth, blackening of the root system and generalized chlorosis. The activity of superoxide dismutase enzyme (SOD; EC 1.15.1.1) and gluta

20. REDESCRIPCIÓN DE POTAMOLITHUS SUPERSULCATUS PILSBRY, 1896 (GASTROPODA, TATEIDAE) DEL SUR DE LA CUENCA DEL PLATA
ABSTRACT The genus Potamolithus Pilsbry, 1896 (Gastropoda; Tateidae), has 31 species, 22 of which are distributed in Argentina in Del Plata basin, defining the Uruguay River and the Río de la Plata as a “hotspot” of diversity in freshwater gastropods. However, most of its species has been described only by conchology characters and a few has anatomical

21. Are astrocytes executive cells within the central nervous system?
ABSTRACT Experimental evidence suggests that astrocytes play a crucial role in the physiology of the central nervous system (CNS) by modulating synaptic activity and plasticity. Based on what is currently known we postulate that astrocytes are fundamental, along with neurons, for the information processing that takes place within the CNS. On the other hand,

22. Mature B cell neoplasms: retrospective analysis of 93 cases diagnosed between 2011 and 2014 in a University Hospital in southern Brazil
ABSTRACT BACKGROUND: According to the 2008 World Health Organization classification, mature B-cell neoplasms are a heterogeneous group of diseases that include B-cell lymphomas and plasma cell disorders. These neoplasms can have very different clinical behaviors, from highly aggressive to indolent, and therefore require diverse treatment strategies. OBJECT

23. EVALUATION OF THE THERAPEUTIC EFFICACY OF LEVAMISOLE HYDROCHLORIDE ON THIRD-STAGE LARVAE OF Lagochilascaris minor IN EXPERIMENTALLY INFECTED MICE
Lagochilascariosis, a disease caused by Lagochilascaris minor, affects the neck, sinuses, tonsils, lungs, the sacral region, dental alveoli, eyeballs and the central nervous system of humans. A cycle of autoinfection may occur in human host tissues characterized by the presence of eggs, larvae and adult worms. This peculiarity of the cycle hinders therapy, s

24. 40K, 226Ra AND 228Ra SERIES IN BOVINE AND POULTRY FEED AND IN DICALCIUM PHOSPHATE (DCP) SAMPLES BY GAMMA-RAY SPECTROMETRY
The aim of this study is to determine the amounts of radionuclides' activity present in samples of feed for young and adult chicken and feed for dairy and beef cattle, as well as in dicalcium phosphate (DCP) (CaHPO4), used as a nutritional supplement for animal feed. Radioactivity in these samples is due to the presence of the 238U and 232Th radioactive seri
