CONTEXT Biomass serves as a major fuel source for >50% of the world's population. The global burden of disease attributed to indoor air pollution from biomass combustion accounts for approximately 3% of worldwide disability-adjusted life-years lost. This is due to pneumonia in children and chronic obstructive pulmonary disease and lung cancer in women. CASE PRESENTATION A 53-year-old man from...

The paper presents the results of our study on effect one type pyrogenic factor (smoke) after burning coniferous wood chips several bioindicators (soil enzymes, microorganisms, mesofauna, plants agricultural crops). Exposition to smoke for 60 minutes was found significantly affect enzymatic activity common chernozem. Fumigation caused a decrease in such enzymes as catalase, peroxidase, polyphen...

The monitoring and tracking of urban air pollution is a challenging environmental issue. approach synchronous 3-D detection wind using solo coherent Doppler lidar (CDWL) developed demonstrated. distribution pollutant depicted by the backscatter coefficient based on signal intensity CDWL. Then, high-resolution field derived to track local source with its diffusion analyze transboundary episodes....

Over the course of industrial manufacturing, additional heat within extract systems is usually released into atmosphere and its intrinsic energy wasted. This paper investigated a cold abatement smoke system for fire testing wall furnace to determine viability in recovering from hot smoke. Three scenarios were investigated: 1) was closed only 300°C present; 2) took ambient air around recovery oc...

The plant hormones strigolactones and smoke-derived karrikins are butenolide signals that control distinct aspects of plant development. Perception of both molecules in Arabidopsis thaliana requires the F-box protein MORE AXILLARY GROWTH2 (MAX2). Recent studies suggest that the homologous SUPPRESSOR OF MAX2 1 (SMAX1) in Arabidopsis and DWARF53 (D53) in rice (Oryza sativa) are downstream targets...

Karrikins are butenolides derived from burnt vegetation that stimulate seed germination and enhance seedling responses to light. Strigolactones are endogenous butenolide hormones that regulate shoot and root architecture, and stimulate the branching of arbuscular mycorrhizal fungi. Thus, karrikins and strigolactones are structurally similar but physiologically distinct plant growth regulators. ...

Cigarette smoke is a profound proinflammatory stimulus that causes acute lung inflammation and chronic lung disease, including chronic obstructive pulmonary disease (COPD, emphysema, and chronic bronchitis), via a variety of mechanisms, including oxidative stress. Cigarette smoke contains high levels of free radicals, whereas inflammatory cells, including macrophages and neutrophils, express en...

Cigarette smoke is the most important environmental risk factor for developing age-related macular degeneration (AMD). Damage to the retinal pigment epithelium (RPE) caused by cigarette smoke may underlie the etiology of AMD. This study investigated the molecular and cellular effects of cigarette smoke exposure on human RPE cells. ARPE-19 or primary human RPE cells were exposed to cigarette smo...
