Oral alterations and oral care in bone marrow transplant patients

Os cuidados gerais relativos ao paciente submetido ao transplante de medula óssea (TMO) incluem avaliações odontológicas rotineiras, as quais devem estar inseridas em um contexto multiprofissional. A cavidade oral constitui um sítio propício a infecções com grande potencial de desenvolvimento de bacteremia, sendo que lesões infecciosas devem ser previamente tratadas e controladas pelo cirurgião-dentista. O objetivo desta revisão é discutir questões em destaque na literatura nacional e internacional referentes aos quadros inflamatórios e infecciosos orais de importância para o paciente transplantado de medula óssea, tanto os predisponentes a complicações durante o transplante, quanto os que ocorrem durante e após a terapia mielossupressora. Destaca-se na literatura a doença periodontal avançada, a qual constitui um quadro infeccioso crônico que deve ser evitado ou controlado durante o TMO, principalmente devido à presença de S. viridans. Os fatores de risco para mucosite oral (OM), doença do enxerto contra o hospedeiro (DECH) e xerostomia ainda não estão definidos, principalmente para OM e DECH. São citadas na literatura alternativas promissoras de tratamento para OM, tais como crioterapia, administração de fatores de crescimento e laserterapia. O risco aumentado de cárie é controverso e, dentre as lesões fúngicas e virais, destacam-se as infecções orais e de orofaringe por Candida e pela família de herpesvírus, de importância clínica considerável. Em pacientes pediátricos são relevantes as alterações craniofaciais e dentárias, decorrentes principalmente da radioterapia.General care in bone marrow transplant (BMT) patients includes routine dental evaluations, which must be included in a multi-professional context. The oral cavity is a site that favors infections with high potential for consequent bacteremia and so infectious lesions must be treated or controlled by the dentist. The aim of this review is to discuss key questions in national and international literature with reference to oral inflammatory conditions of BMT patients, both those with predisposition to complications during the transplant and those that emerge during and after myelosuppression therapy. The literature emphasizes advanced periodontal disease, which is a chronic infectious condition that must be avoided or controlled during BMT, particularly because of the presence of S. viridans. The risk factors for oral mucositis, graft-versus-host disease (GVHD) and xerostomia have not yet been defined, particularly for oral mucositis and GVHD. Promising alternatives in the treatment of oral mucositis, including cryotherapy, administration of growth factors and laser therapy, are emphatically mentioned. In children, craniofacial and dental alterations, particularly resulting from radiotherapy are relevant. The increased risk of caries is controversial, and among fungal and viral lesions, oral and oropharyngeal infections by Candida and the herpes virus are identified as being of considerable clinical importance

Evolutionary processes underlying latitudinal differences in reef fish biodiversity

Aim: To examine the dynamics among the processes of speciation, extinction and dispersal in marine environments using phylogenies to reveal the evolutionary mechanisms that promote latitudinal differences in biodiversity. Using phylogenetic comparative methods we assess whether tropical reef fish lineages show higher diversification rates and whether the majority of extratropical reef fish lineages have originated from tropical areas. Location: Shallow water tropical and extratropical reefs globally. Methods: Using fossil-calibrated phylogenies for four reef-associated fish families (Chaetodontidae, Labridae, Pomacentridae and Sparidae) we apply evolutionary models (GeoSSE and HiSSE) that allow the estimation of speciation, extinction and dispersal rates associated with geographical ranges and explore potential biases from unsampled characters. Results: We found that tropical lineages show higher rates of speciation and tended to have lower extinction rates. Overall, we identify higher net diversification rates for tropical lineages compared with those in extratropical regions in all four families. Rates of dispersal tended to be higher for lineages with tropical origins expanding into extratropical regions. Within the family Labridae, two tropical lineages were found to exhibit higher net diversification rates, above that expected from latitudinal differences. Main conclusions : Our results offer support for the predictions of the out of the tropics' and evolutionary speed' models of evolution, both of which highlight the marine tropics as an important evolutionary engine promoting latitudinal differences in reef fish biodiversity. Moreover, we find that two tropical labrid lineages are undergoing exceptional diversification associated with additional traits, possibly linked with the extreme sexual dichromatism observed in both clades

Ultrasound-assisted drying of orange peel in atmospheric freeze-dryer and convective dryer operated at moderate temperature

This is an Author's Accepted Manuscript of an article published in Ronaldo E. Mello, Alessia Fontana, Antonio Mulet, Jefferson Luiz, G. Correa & Juan A. Cárcel (2020) Ultrasound-assisted drying of orange peel in atmospheric freeze-dryer and convective dryer operated at moderate temperature, Drying Technology, 38:1-2, 259-267, DOI: 10.1080/07373937.2019.1645685 [copyright Taylor & Francis], available online at: http://www.tandfonline.com/10.1080/07373937.2019.1645685[EN] Atmospheric freeze-drying (AFD) at -10 degrees C and moderate temperature convective drying (MTD) at 50 degrees C without and with ultrasound application (20.5 kW/m(3)) were carried out. Alcohol insoluble residue (AIR) and its swelling capacity (SC), water retention capacity (WRC) and fat retention capacity (FRC) were measured in the dried product. Ultrasound significantly shortened the drying time in both processes, the intensification effect being more significant in atmospheric freeze-drying (57% and 27% reduction in atmospheric freeze-drying and convective drying, respectively). As regards AIR and WRC, no effect was observed of either the drying temperature or ultrasound application. On the contrary, SC was significantly lower in AFD samples. The FRC of MTD samples was similar to that of the fresh ones and higher than the values obtained for atmospheric freeze-dried samples. Therefore, convective drying at moderate temperature preserved the AIR properties better than atmospheric freeze-drying.The authors acknowledge the financial support of INIA-ERDF through project RTA2015-00060-C04-02.

Phenolic compounds, organic acids and antioxidant activity of grape juices produced from new Brazilian varieties planted in the Northeast Region of Brazil.

The phenolic compounds, organic acids and the antioxidant activity were determined for grape juice samples from new Brazilian varieties grown in the Sub-middle São Francisco Valley in the Northeast Region of Brazil. The results showed that the Brazilian grape juices have high antioxidant activity, which was significantly correlated with the phenolic compounds catechin, epicatechin gallate, procyanidin B1, rutin, gallic acid, caffeic acid, p-coumaric acid, pelargonidin-3-glucoside, cyanidin-3-glucoside, cyaniding-3,5-diglucoside and delphinidin-3-glucoside. The produced juice samples showed higher concentrations of trans-resveratrol than those observed in juices made from different varieties of grapes from traditional growing regions. Organic acids concentrations were similar to those of juices produced from other classical varieties. It was demonstrated that it is possible to prepare juices from grapes of new varieties grown in the Northeast of Brazil containing a high content of bioactive compounds and typical characteristics of the tropical viticulture practised in the Sub-middle São Francisco Valley

Electronic Tongue Based on Nanostructured Hybrid Films of Gold Nanoparticles and Phthalocyanines for Milk Analysis

The use of gold nanoparticles combined with other organic and inorganic materials for designing nanostructured films has demonstrated their versatility for various applications, including optoelectronic devices and chemical sensors. In this study, we reported the synthesis and characterization of gold nanoparticles stabilized with poly(allylamine hydrochloride) (Au@PAH NPs), as well as the capability of this material to form multilayer Layer-by-Layer (LbL) nanostructured films with metal tetrasulfonated phthalocyanines (MTsPc). Film growth was monitored by UV-Vis absorption spectroscopy, atomic force microscopy (AFM), and Fourier transform infrared spectroscopy (FTIR). Once LbL films have been applied as active layers in chemical sensors, Au@PAH/MTsPc and PAH/MTsPc LbL films were used in an electronic tongue system for milk analysis regarding fat content. The capacitance data were treated using Principal Component Analysis (PCA), revealing the role played by the gold nanoparticles on the LbL films electrical properties, enabling this kind of system to be used for analyzing complex matrices such as milk without any prior pretreatment

Métodos de campo para o estudo de formigas em cultivo de cana-de-açúcar na região sudeste do Brasil

The harvest of sugarcane is still traditionally done manually with the burning of straw in most cultivated areas in Brazil. However, burning has been gradually eliminated with the relatively recent use of mechanical harvesting. This will result in significant changes in the agroecosystem, as the straw will remain in the field. No investigation on Formicidae found in sugarcane plantations in Southeastern Brazil harvested by this new system has been done yet. Because of their feeding habits, many species of this family may act as predators of several sugarcane pests. In this study, the sampling efficacy of pitfall traps, baits, and underground traps with two types of attractants were evaluated. Pitfall traps gave the largest richness, while abundance was the highest from baiting. Community composition and structure differed in relation to the sampling methods used. The myrmecofauna collected with the same method with different baits was similar. Pitfall trapping was the most efficient method in this type of ecosystem; and sardine, the best attractant, due to its easy handing in the field.A colheita de cana-de-açúcar é efetuada manualmente e com a queima da palha em grande parte da área de cultivo. Porém, esse manejo deverá ser completamente substituído pela mecanizado. O emprego desse sistema de colheita é relativamente recente e pode resultar em alterações significativas no agroecossistema, em função da manutenção da palha no ambiente. Descrições sobre métodos de coleta de Formicidae, cujas espécies podem ser predadoras de diversas pragas da cultura, ainda são inexistentes em agroecossistemas que usam esse novo tipo de manejo. Assim, o objetivo do trabalho foi avaliar o uso de diferentes métodos de coleta: pitfall, isca e armadilhas subterrâneas; sendo os dois últimos com dois tipos de atrativos. A maior riqueza foi obtida com pitfall e a maior abundância com isca; a composição e a estrutura das comunidades diferem em relação ao método usado. A fauna coletada com um mesmo método, porém com atrativos diferentes, é similar. O uso de pitfall proporciona a amostragem da fauna predadora do cultivo, o que é importante para os programas de controle natural de pragas; e para quantificar a abundância da maior parte dessa fauna, a sardinha é o melhor material atrativo, devido à facilidade de manipulação no campo
