1. Histopathological characterization of Coffea arabica cultivar IPR 106 resistance to Meloidogyne paranaensis
ABSTRACT: Meloidogyne species are widely distributed in coffee growing areas in Brazil, where M. paranaensis is responsible to significant losses to the crop. One of the main management strategies is the use of resistant cultivars, such as Apoatã rootstock and cultivars IPR 100 and IPR 106. However, the parasitic relationship between coffee and M. paranaens

2. Does hypersensitive teeth show pulp inflammation?
RESUMO Objetivo: Este estudo investigou a presença de resposta inflamatória na polpa dentária de ratos apresentando hipersensibilidade dentinária induzida por episódios erosivos. Métodos: Dezesseis ratos Wistar foram alimentados com ração peletizada isenta de sacarose por 12 horas; enquanto a dieta estava ausente no restante do período diário, os

3. An experimental study of exenatide effects on renal injury in diabetic rats
Abstract Purpose: To investigate the effects of exenatide on renal injury in streptozotocin-induced diabetic rats. Methods: Fifty SD rats were randomly divided into normal control, model, exenatide-1, exenatide-2 and exenatide-3 groups, 10 rats in each group. The diabetic nephropathy model was constructed in later 4 groups. Then, the later 3 groups were

4. Correlation of serum IgE levels and clinical manifestations in patients with actinic prurigo
Abstract BACKGROUND: Actinic prurigo is an idiopathic photodermatosis, the pathophysiology of which has been hypothesized to involve subtype IV type b (Th2) hypersensitive response, whereby IL4, IL5, and IL13 are secreted and mediate the production of B cells, IgE, and IgG4. OBJECTIVES: To examine the association of serum IgE levels and the clinical severi

5. Defense responses to Meloidogyne exigua in resistant coffee cultivar and non-host plant
The resistance of coffee plants to Meloidogyne exigua is conferred by the gene Mex-1. However, the mechanisms of resistance still need to be clarified. Therefore, the penetration, development and reproduction of two populations of M. exigua (M1, isolated from the coffee plant and M2, from rubber tree) in susceptible (Coffea arabica 'Catuai') and resistant (C

6. Interação molecular planta-nematóide.
ABSTRACT: The endoparasitic sedentary phytonematodes of genera Heterodera, Globodera (known as cyst nematodes, CN) and Meloidogyne (the root-knot nematodes, RKN) are major crop phytopathogens, causing estimated losses of US$ 125 billion annually in the world. These plant-parasitic nematodes share some parasitism mechanisms, which ensure host-tissue invasion

7. Functional changes of dendritic cells in hypersensivity reactions to amoxicillin
A better understanding of dendritic cell (DC) involvement in responses to haptenic drugs is needed, because it represents a possible approach to the development of an in vitro test, which could identify patients prone to drug allergies. There are two main DC subsets: plasmacytoid DC (pDC) and myeloid DC (mDC). β-lactams form hapten-carrier conjugates and ma

8. Ocorrência, identificação e caracterização das espécies de xanthomonas, causadoras de mancha bacteriana em tomate para mesa no Brasil
Tomato bacterial spot is caused by at least four Xanthomonas species (Xanthomonas euvesicatoria, X. vesicatoria, X. perforans and X. gardneri), and is one of the most important diseases of both processing and fresh market tomato crops in Brazil. Eighty one isolates, collected from 23 commercial tomato fields, located in southern, southeastern, central-west a

9. Caracterização dos componentes extracelulares produzidos em cultura de célula de Rubus fruticosus (amora-preta) durante resposta de hipersensibilidade / Characterization of the extracellular compounds released from Rubus fruticosus (blackberry) cell during a hypersensitive response.
The plant-pathogen interactions trigger a series of signals that are not yet completely understood. One of the mechanisms is the hypersensitive response (HR), which is characterized by cell death in the infection site in order to prevent pathogen proliferation. Our previous studies with different elicitors demonstrated the correlation between the formation o

10. Identificação de genes diferencialmente expressos em tomateiro induzidos por ácido salicílico e por Fusarium oxysporum f. sp. lycopersici.
To identify tomato plant (Lycopersicon esculentum Mill), cv. BRH, genes which answer to plant pathogen Fusarium oxysporum f. sp. lycopersici and salicylic acid, the carrier molecule for activation of responses of plant defense, it was used the suppression subtractive hybridization (SSH) technique, from leaf cDNAs, 24h after salicylic acid, library denominate

11. Genes associated with hypersensitive response (HR) in the citrus EST database (CitEST)
Plants are continuously exposed to pathogen attack, but successful infection is rare because they protect themselves against pathogens using a wide range of response mechanisms. One of them is the hypersensitive response (HR), which is a form of cell death often associated with plant resistance to pathogen infection to prevent the [email protected] sebpg@c

12. study of the effects of hypersensitive response on cell wall in blackberry-black cell culture (Rubus fruticosus) / Estudo do efeito de respostas de hipersensibilidade sobre a parede celular em cultura de células de amora-preta (Rubus fruticosus)
Como os outros organismos, as plantas têm a habilidade de se defenderem através do reconhecimento de patógenos (resposta de hipersensibilidade - RH), causando a morte imediata das células no sítio primário da infecção, desta maneira oferecendo resistência ao seu crescimento. A RH é caracterizada pela necrose dos tecidos neste local, através de mui
