Gama-Lactones from Iryanthera species

The structure of juruenolide, a constituent of Iryanthera juruensis and I. ulei is revised to (2S, 3R, 4S)-3-hydroxy-4-methyl-2-(19′-piperonyl-1′-n-nonadecyl)-butanolide. The compound is epimeric at C-3 of the γ-lactone unit with grandinolide [(2S, 3S, 4S)-3-hydroxy-4-methyl-2- (19′-phenyl-1′-n-nonadecyl)-butanolide] from I. grandis. An extract of I. juruensis contained additionally juruenolide-B [(4S)-4-methyl-2-(19′-piperonyl-1′-n-nonadec-7′-enyl)-but-2-enolide]. Analogous products with heptadecyl and pentadecyl side chains co-occur with the respective nonadecyl derivatives. © 1983.

Different esthetic techniques used in combination to improve the smile

This is a clinical case report of a patient who presented with dental stains in the buccal and proximal aspects of the anterior teeth. Buccal stains were removed using the enamel microabrasion technique, and vital tooth bleaching with carbamide peroxide was also performed. Restorative procedures employing composite resin were done for a better result in the proximal aspect of teeth. Clinical significance: The authors observed the combination of these esthetic techniques improved the patient's smile. Today, dental esthetics attempts to imitate natural teeth by making them white, well-shaped, and aligned with no spots. This has enabled the development of several esthetic techniques, such as microabrasion to remove dental enamel surface stains and surface irregularities,1-6 and vital tooth bleaching to treat yellowish teeth.7 The enamel microabrasion technique uses different abrasive agents associated with chemical solutions,1,2,4,6 allowing the removal of intrinsic, hard-texture stains, and different coloring spots on the enamel surface, as well as correction of irregularities on the dental buccal surface.1,8 The various microabrasive products include the Opalustre® (Ultradent Products, http://www.ultradent.com)or Prema® Compound (Premier Dental Products, http://www.premusa.com), a low-concentration hydrochloric acid product associated with silica microparticles that is certainly effective for microabrasion technique,4,6,9,10 providing a good safety profile for the patient and professional. The microabrasion technique also promotes micro-reduction on the adamantine surface.4,5,10 In some cases, after its completion, microabrasion may cause teeth to become darker or yellowish because of the thinner remaining enamel surface, leading to more evident observation of the dentinal tissue, which in general determines tooth color. In these clinical conditions, correction of the color pattern of dental elements can be obtained with carbamide peroxide products applied in custom trays, such as the bleaching products Whiteness Perfect at 10% or 16% (FGM Productos Odontologicos, http://www.fgm.ind.br) or Opalescence® at 10% or 15% (Ultradent Products), with a considerable margin of clinical success, provided it is well indicated, well performed, and supervised by the professional.4,6,9,10 Considering all the aforementioned aspects, the authors present a clinical case about a dental-enamel microabrasion technique used to remove buccal enamel surface stains associated with dental vital bleaching and restorative procedures in the proximal aspect of anterior teeth. - See more at: https://www.dentalaegis.com/cced/2010/08/different-esthetic-techniques-used-in-combination-to-recover-the-smile#sthash.McFoH7El.dpuf

Detecção de Brucella spp. em leite bovino não pasteurizado através da Reação de Cadeia pela Polimerase (PCR)

Brucellosis is a zoonosis caused by bacteria of the genus Brucella. Man infection occurs through contact with reproductive secretions as placenta and its lochia, semen and penile secretion of infected animals or by consuming unpasteurized milk and dairy products. With the objective of investigating the presence of bacteria in milk, 30 samples of raw milk sold illegally in the region of Botucatu, São Paulo, Brazil, as well as 50 samples of milk delivered to a dairy industry previously to its pasteurization were evaluated by the polymerase chain reaction (PCR) technique. Of the 80 samples analyzed, 10 samples (12.5%) were positive and 70 (87.5%) were negative. Among the  positive samples,  5 (16.6%)  were from  illegal traders  and other  5  (10%) were obtained  from the dairy industry. Brucella spp. positivity shows that the pathogen is representatively present in Botucatu, São Paulo, Brazil, and the risk associated to public health due to the commercialization of illegal products without pasteurization is real.
