1. Evaluation of some oxidative-stress and antioxidant markers in goats during estrous cycle under Egyptian environmental conditions
ABSTRACT The objective of this study was to explore the impact of thermal stress on hormonal level and antioxidant activity in goats during various phases of the estrous cycle in the Egyptian summer. Forty cycling does were allocated to two groups (20 animals each) divided by season (mild/hot). Daily meteorological, rectal temperature, and respiratory rate d

2. Inhibitory effects on the production of inflammatory mediators and reactive oxygen species by Mori folium in lipopolysaccharide-stimulated macrophages and zebrafish
ABSTRACT Mori folium, the leaf of Morus alba L. (Moraceae), has been traditionally used for various medicinal purposes from ancient times to the present. In this study, we examined the effects of water extract of Mori folium (WEMF) on the production of inflammatory mediators, such as nitric oxide (NO) and prostaglandin E2 (PGE2), and reactive oxygen species

3. Mechanisms of action underlying the anti-inflammatory and immunomodulatory effects of propolis: a brief review
Many biological properties have been attributed to various types of propolis, including anti-inflammatory, antimicrobial, antioxidant, antitumor, wound healing, and immunomodulatory activities. This article reviewed studies published that investigated the anti-inflammatory activity of propolis of different origins and/or its isolated components, focusing on

4. Efeito anti-inflamatório do óleo essencial de Croton zehntneri pax et hofmm e do Anetol. / Anti-inflammatory effect of essential oil of Croton et pax zehntneri hofmm and Anethole.
Essential oils from the gender Croton (Euphorbiaceae) are sources of bioactive molecules, from which are obtained several compounds of diverse chemical groups and great therapeutic potential in folk medicine. The essential oil of Croton zehntneri (EOCz), popularly known as Canela-de-Cunhã, possesses anethole, estragole and eugenol as the main constituents.

6. Antiulcenogenic activity of native plants of the São Paulo State savannah pertaining to the genre Indigofera / Atividade antiulcerogenica de plantas nativas do cerrado do estado de São Paulo - pertencentes ao genero Indigofera
The genus Indigofera, which includes 700 herbaceous and bush species, is one of the six largest Leguminosae genres. In São Paulo State, Brazil, nine species of this genre were already described. Indigofera truxillensis Kunt and Indigofera suffruticosa Mill, commonly known as ?índigo?, are found predominately at São Paulo State?s savannah. There are just a

7. Glomerular actions of a free radical-generated novel prostaglandin, 8-epi-prostaglandin F2 alpha, in the rat. Evidence for interaction with thromboxane A2 receptors.
8-epi-prostaglandin F2 alpha (8-epi-PGF2 alpha) and related compounds are novel prostanoid produced by a noncyclooxygenase mechanism involving lipid peroxidation. Renal ischemia-reperfusion injury increased urinary excretion of these compounds by 300% over baseline level. Intrarenal arterial infusion at 0.5, 1, and 2 micrograms/kg per min induced dose-depend

8. Transcription Factor Nrf2 Regulates Inflammation by Mediating the Effect of 15-Deoxy-Δ12,14-Prostaglandin J2
Activated macrophages express high levels of Nrf2, a transcription factor that positively regulates the gene expression of antioxidant and detoxication enzymes. In this study, we examined how Nrf2 contributes to the anti-inflammatory process. As a model system of acute inflammation, we administered carrageenan to induce pleurisy and found that in Nrf2-defici

9. Human platelets modulate edema formation in isolated rabbit lungs.
The role of platelet glucose-6-phosphate dehydrogenase (G-6-PD) in mediating the effects of human platelets on oxidant-induced edema in the isolated perfused rabbit lung was investigated using dehydroepiandrosterone, a specific steroidal inhibitor of G-6-PD. Xanthine oxidase (0.003 and 0.012 U/ml) caused lung edema that was attenuated by coinfusion of washed

10. Thermosensitive phenotype of transgenic mice overproducing human glutathione peroxidases.
Exposure of humans and other mammals to hyperthermic conditions elicits many physiological responses to stress in various tissues leading to profound injuries, which eventually result in death. It has been suggested that hyperthermia may increase oxidative stress in tissues to form reactive oxygen species harmful to cellular functions. By using transgenic mi

11. Thioredoxin Peroxidase Secreted by Fasciola hepatica Induces the Alternative Activation of Macrophages
Alternatively activated macrophages (AAMφ) are primarily associated with the chronic stages of parasitic infections and the development of a polarized Th2 response. We have shown that Fasciola hepatica infection of BALB/c mice induces a polarized Th2 response during both the latent and chronic stage of disease. The activation status of macrophages was analy

12. Formation of non-cyclooxygenase-derived prostanoids (F2-isoprostanes) in plasma and low density lipoprotein exposed to oxidative stress in vitro.
F2-isoprostanes are prostaglandin F2-like compounds that are known to be formed in vivo by free radical oxidation of arachidonyl-containing lipids, and their plasma levels have been suggested as indicators of in vivo oxidative stress. As oxidation of LDL, a likely causal factor in atherosclerosis, involves lipid peroxidation, we investigated whether F2-isopr
