13. Innate immunity and effector and regulatory mechanisms involved in allergic contact dermatitis
Abstract: Skin's innate immunity is the initial activator of immune response mechanisms, influencing the development of adaptive immunity. Some contact allergens are detected by Toll-like receptors (TLRs) and inflammasome NLR3. Keratinocytes participate in innate immunity and, in addition to functioning as an anatomical barrier, secrete cytokines, such as TN

14. Photosynthetic capacity and water use efficiency in Ricinus communis (L.) under drought stress in semi-humid and semi-arid areas
ABSTRACT Castor bean is one of the crops with potential to provide raw material for production of oils for biodiesel. This species possess adaptive mechanisms for maintaining the water status when subjected to drought stress. A better understanding these mechanisms under field conditions can unravel the survival strategies used by this species. This study ai

15. ANALYTICAL COMPARISON OF THE PERFORMANCE OF ADAPTIVE MODULATION AND CODING IN WIRELESS NETWORK UNDER RAYLEIGH FADING
Abstract In this paper, an analytic comparison between adaptive modulation (AdM) and adaptive Forward Error Correction (AdFEC) in wireless network telecommunication systems is performed. Through the Gilbert-Elliott model's, the Packet Error Rate (PER) is calculated and both the throughput and the delay, for different modulations and error correction capacity

16. Wound healing treatment by high frequency ultrasound, microcurrent, and combined therapy modifies the immune response in rats
BACKGROUND: Therapeutic high-frequency ultrasound, microcurrent, and a combination of the two have been used as potential interventions in the soft tissue healing process, but little is known about their effect on the immune system. OBJECTIVE: To evaluate the effects of therapeutic high frequency ultrasound, microcurrent, and the combined therapy of the

17. SELECTING PROFILES OF IN DEBT CLIENTS OF A BRAZILIAN TELEPHONE COMPANY: NEW LASSO AND ADAPTIVE LASSO ALGORITHMS IN THE COX MODEL
Variable selection plays an important rule in identifying possible factors that could predict the behavior of clients with respect to the bill payments. The Cox model is the standard approach for modeling the time until starting the lack of payments. Parsimony and capacity of predicting are some desirable characteristics of statistical models. This paper aim

18. Plasticity of neutrophils reveals modulatory capacity
Neutrophils are widely known as proinflammatory cells associated with tissue damage and for their early arrival at sites of infection, where they exert their phagocytic activity, release their granule contents, and subsequently die. However, this view has been challenged by emerging evidence that neutrophils have other activities and are not so short-lived.

19. A pré-medicação com midazolam antes de secção cesariana não tem efeitos adversos no neonato
Como todos os pacientes cirúrgicos, pacientes obstétricas também sentem estresse e ansieda de operatórios. Isso pode ser prevenido se forem passadas à paciente informações detalhadas sobre sua operação e se forem administrados medicamentos farmacológicos pré-operatórios. Devido aos efeitos depressivos dos sedativos nos neonatos, os medicamentos f

20. Efeitos das mudanças socioecológicas sobre a pesca artesanal e a captura incidental de Tartarugas Marinhas no Bairro São Francisco (São Sebastião, São Paulo) / Social-ecological change effects on artisanal fisheries and sea turtle by cath in São Francisco (São Sebastião, São Paulo)
O objetivo deste estudo foi investigar como as mudanças sócio ecológicas afetam a pesca artesanal e a captura incidental de tartarugas marinhas no bairro São Francisco (São Sebastião, São Paulo) e como os pescadores estão respondendo às alterações nos últimos 60 anos. Para tanto, a capacidade adaptativa de sistemas complexos e o conhecimento ecol

21. Determinantes da fraqueza e propriedades contráteis da musculatura inspiratória na insuficiência cardíaca
The inspiratory muscle weakness may be present in 30-50% of outpatients with chronic heart failure, with implications for the quality of life and prognosis. However, it is unclear what clinical and behavioral characteristics that would be associated with this dysfunction. Moreover, as are unclear the molecular mechanisms leading to dysfunction of the diaphra

22. Processamento de sinais de descargas parciais em tempo real com base em wavelets e seleção de coeficientes adaptativa espacialmente
On-line partial discharge (PD) analysis is a highly pursued feature due to the economy related to scheduled shutdowns, disassembling and transport. Nevertheless, on-site PD measurements are frequently limited by interferences found in high-voltage facilities, a situation that imposes the continued development of PD signal processing methods. In the last year

24. Identificación de mega‑ambientes para potenciar el uso de genotipos superiores de arroz en Panamá
The objective of this work was to evaluate three methods to identify mega‑environments, in order to optimize the use of the genetic potential of rice cultivars during the selection process and to make recommendations for commercial plantations in Panama. Experimental data were obtained from the test performance, between 2006 and 2008, for early maturing cu
