Background. Smoking is a risk factor for gastroduodenal ulcer and gastric adenocarcinoma. However, the pathophysiological mechanisms induced by acute cigarette smoking in the human gastric mucosa are poorly understood. ...

Fire-related cues may enhance seed recruitment in flammable ecosystems and differences in fire-germination responses of invasive vs. native species can drive the invasion process. We evaluated the effects of heat shock and ...

The effects of four medicinal herbs (Arctium lappa, Plantago major, Mikania glomerata Spreng and Equisetum arvense) with anti-inflammatory properties were evaluated in a chronic obstructive pulmonary disease (COPD) model. ...

Flammable ecosystems host plants with different strategies in response to fire, such as increasing germination after the exposure to smoke and dormancy breaking by heat shocks. Cerrado is a fire-prone ecosystem, but less ...

The Cerrado (Brazilian savanna) is a biodiversity hotspot with a history of fire that goes back as far as 10 million years. Fire has influenced the evolution of several aspects of the vegetation, including reproduction and ...

Objective Experimental studies have shown that exposure to cigarette smoke has negative effects on lipid metabolism and oxidative stress status. Cigarette smoke exposure in nonpregnant and pregnant rats causes significant ...
