1. Effect of Lavandula dentata extract on Ovalbumin-induced Asthma in Male Guinea Pigs
Resumo A asma é uma doença inflamatória dos pulmões e causa estresse oxidativo. Lavandula dentata é uma erva aromática com atividades anti-oxidantes e antiinflamatórias. Este estudo examinou a atividade do extrato de L. dentata em um modelo de asma de cobaia. Os machos adultos foram divididos em cinco grupos: o primeiro grupo foi controle, o segundo

2. Stability and rheological behavior of coconut oil-in-water emulsions formed by biopolymers
Abstract Proteins are frequently used as emulsifiers and stabilizers. In this work, two proteins with different isoelectric points were used: lactoferrin and ovalbumin. Solutions containing different proteins ratios, with different pH values, were stored for 7 days at 25 °C to analyze the system stability. Systems containing 3% w/v lactoferrin remained sta

3. Imbalance of γδT17/γδTreg cells in the pathogenesis of allergic asthma induced by ovalbumin
We aimed to explore the imbalance between the T helper 17 γδT cells (γδT17) and the regulatory γδT cells (γδTreg) in asthmatic mice. Male Balb/c mice were randomly divided into the normal control group and the asthmatic model group. The asthmatic model group mice were intraperitoneally injected with the mixture of ovalbumin (OVA)/Al(OH)3 and then act

4. Warifteine, an alkaloid of Cissampelos sympodialis, modulates allergic profile in a chronic allergic rhinitis model
ABSTRACT Cissampelos sympodialis Eichler, Menispermaceae, a Brazilian medicinal plant and its alkaloid warifteine present immunomodulatory activity on asthma experimental model by reducing antigen-specific IgE levels, eosinophil infiltration and lung hyperactivity. Allergic rhinitis is a chronic inflammatory disorder of the nasal tissue that affect the quali

5. Tangeretin has anti-asthmatic effects via regulating PI3K and Notch signaling and modulating Th1/Th2/Th17 cytokine balance in neonatal asthmatic mice
Asthma is a chronic allergic disease characterized by airway inflammation, airway hyper-responsiveness (AHR), and mucus hypersecretion. T-lymphocytes are involved in the pathogenesis of asthma, mediating airway inflammatory reactions by secreting cytokines. The phosphoinositide 3-kinase (PI3K) and Notch signaling pathways are associated with T cell signaling

6. Gene Polymorphisms are Associated with Eggshell Ultrastructure Organization in Hens
ABSTRACT Background: Eggshell ultrastructure organization, including effective layer thickness, mammillary layer thickness, and average size of mammillary cones, is important for breeding and significantly influences eggshell mechanical properties. Several matrix proteins were known to be important in eggshell formation. However, the proteins and variation

7. Enhancement of anti-OVA IgG2c production in vivo by enalapril
Angiotensin-converting enzyme (ACE) inhibitors have non-hemodynamic, pleiotropic effects on the immune response. The effects of ACE inhibitors on the production of cytokines and T-cell functions are well established. However, little is known on the effects of these medicines on humoral response to foreign antigens. In this study, we investigated the effect o

8. Gestation and breastfeeding in schistosomotic mothers differently modulate the immune response of adult offspring to postnatal Schistosoma mansoni infection
Schistosoma mansoni antigens in the early life alter homologous and heterologous immunity during postnatal infections. We evaluate the immunity to parasite antigens and ovalbumin (OA) in adult mice born/suckled by schistosomotic mothers. Newborns were divided into: born (BIM), suckled (SIM) or born/suckled (BSIM) in schistosomotic mothers, and animals from n

9. Toxocara canis and the allergic process
The protective effect of infectious agents against allergic reactions has been thoroughly investigated. Current studies have demonstrated the ability of some helminths to modulate the immune response of infected hosts. The objective of the present study was to investigate the relationship between Toxocara canis infection and the development of an allergic re

10. Treatment with 1,25(OH)2D3induced HDAC2 expression and reduced NF-κB p65 expression in a rat model of OVA-induced asthma
Recent evidence indicates that a deficiency of 1,25-dihydroxyvitamin D3 (1,25[OH]2D3) may influence asthma pathogenesis; however, its roles in regulating specific molecular transcription mechanisms remain unclear. We aimed to investigate the effect of 1,25(OH)2D3 on the expression and enzyme activity of histone deacetylase 2 (HDAC2) and its synergistic effec

11. The preventive effects of natural adjuvants, G2 and G2F on tracheal responsiveness and serum IL-4 and IFN-γ (th1/th2 balance) in sensitized guinea pigs
OBJECTIVE:The effects of natural adjuvants on lung inflammation and tracheal responsiveness were examined in sensitized guinea pigs.METHODS:The responses of guinea pig tracheal chains and the serum levels of interleukin-4 and interferon-gamma were examined in control pigs and three other groups of guinea pigs: the sensitized group and two other sensitized gr

12. Synthesis and evaluation of artificial antigens for astragaloside IV
The objective of this study was to produce artificial antigens for astragaloside IV that could be used to prepare antibodies against astragaloside IV screened in Radix astragali (Astragalus membranaceus (Fisch) Bunge, Fabaceae) and its preparations, using an indirect ELISA. Astragaloside IV was coupled to carrier proteins, bovine serum albumin and ovalbumin
