Cicatrização: conceitos atuais e recursos auxiliares - Parte II

Abstract: Na Parte I deste artigo, publicada na edicao anterior dos Anais Brasileiros de Dermatologia, foram revisados os conceitos de cicatrizacao e foi ressaltada a importância da atuacao multidisciplinar na abordagem das feridas, compreendendo-se o paciente como um todo. Nesta Parte II sao apresentados os recursos que podem auxiliar o processo de cicatrizacao, bem como os diversos tipos de curativos disponiveis e a sua respectiva indicacao.

Antimicrobial Photodynamic Therapy Combined With Conventional Endodontic Treatment to Eliminate Root Canal Biofilm Infection

Abstract: Background and Objective: To compare the effectiveness of antimicrobial photodynamic therapy (PDT), standard endodontic treatment and the combined treatment to eliminate bacterial biofilms present in infected root canals. Study Design/Materials and Methods: Ten singlerooted freshly extracted human teeth wereinoculated with stable bioluminescent Gram-negative bacteria, Proteus mirabilis and Pseudomonas aeruginosa to form 3-day biofilms in prepared root canals. Bioluminescence imaging was used to serially quantify bacterial burdens. PDT employed a conjugate between polyethylenimine and chlorin(e6) as the photosensitizer (PS) and 660-nm diode laserlightdeliveredintotherootcanalviaa200-mfiber,and thiswascomparedandcombinedwithstandardendodontic treatment using mechanical debridement and antiseptic irrigation. Results: Endodontic therapy alone reduced bacterial bioluminescence by 90% while PDT alone reduced bioluminescence by 95%. The combination reduced bioluminescence by >98%, and importantly the bacterial regrowth observed 24 hours after treatment was much less for the combination (P<0.0005) than for either single treatment.

Rapid responses of plants to temperature changes

Abstract: Temperature is one of the main environmental factors that affect plant metabolism. Considering that plants are sessile, their survival depends on the efficient activation of resistance responses to thermal stress. In this comprehensive review, we discuss recent work on rapid biochemical and physiological adjustments, herein referred to as those occurring during the first few hours or a few days after the beginning of the change in the ambient temperature. The short-term metabolic modulation after plant exposure to heat and cold, including chilling and freezing, is discussed. Effects on photosynthesis, cell membranes, antioxidant system, production of heat shock proteins and nitric oxide, as well as an overview of signaling events to heat or cold stress are presented. In addition, we also discuss the acclimation process that occurs when the plant acquires resistance to an increase or decrease in temperature, adjusting its homeostasis and steady-state physiology to the new temperatures. Finally, we present studies with tropical plants that aim at elucidating the effects of temperature and the identification of the resilience levels of these plants to the expected climate changes, and which seek the development of techniques for germplasm conservation of endangered species.
