Modeling the key factors that could influence the diffusion of CO from a wellbore blowout in the Ordos Basin, China.

Carbon dioxide (CO) blowout from a wellbore is regarded as a potential environment risk of a CO capture and storage (CCS) project. In this paper, an assumed blowout of a wellbore was examined for China's Shenhua CCS demonstration project. The significant factors that influenced the diffusion of CO were identified by using a response surface method with the Box-Behnken experiment design.

[Disease resistance signal transfer between roots of different tomato plants through common arbuscular mycorrhiza networks].

Common mycorrhizal networks (CMNs) are the underground conduits of nutrient exchange between plants. However, whether the CMNs can serve as the underground conduits of chemical communication to transfer the disease resistance signals between plants are unknown. By inoculating arbuscular mycorrhizal fungus (AMF) Glomus mosseae to establish CMNs between 'donor' and 'receiver' tomato plants, and by inoculating Alternaria solani, the causal agent of tomato early blight disease, to the 'donor' plants, this paper studied whether the potential disease resistance signals can be transferred between the 'donor' and 'receiver' plants roots.

[Mechanism of tomato plants enhanced disease resistance against early blight primed by arbuscular mycorrhizal fungus Glomus versiforme].

Arbuscular mycorrhiza (AM) can not only improve host plants nutrient absorption, but also enhance their disease resistance. Taking the tomato (Lycopersicon esculentum) seedlings preinoculated with axbuscular mycorrhizal fungus (AMF) Glomus versiforme as test materials, this paper studied their protective enzyme activities and defense-related genes expression, and their resistance against a fungal pathogen Alternaria solani Sorauer which causes early blight. The seedlings pre-inoculated with AMF and later inoculated with A.

Smoking risk and the likelihood of quitting among African-American female light and heavy smokers.

While African-American females are more likely to be light smokers compared to their counterparts of other racially classified social groups (RCSGs), they are more likely to carry a heavier burden of smoking-related morbidity and mortality. Thus, it is critical that African-American female light smokers are targeted to engage in smoking cessation. Research has revealed that African-American women are less likely to have a successful quit attempt following a cessation intervention than females from other RCSGs.

Identification and synthesis of novel alkaloids from the root system of Nicotiana tabacum: affinity for neuronal nicotinic acetylcholine receptors.

A novel pyridine derivative, 3,5-bis-(1-methyl-pyrrolidin-2-yl)-pyridine, and a pair of diastereomers of 1,1'-dimethyl-[2,3']bipyrrolidinyl were isolated from the root of Nicotiana tabacum plants and identified as novel alkaloids by GC-MS analysis. The structures of these new alkaloids were confirmed by total synthesis. The affinities of these novel alkaloids, and other structurally related compounds for alpha4beta2*, alpha7* neuronal nicotinic acetylcholine receptors (nAChRs), and for nAChRs mediating nicotine-evoked dopamine release from rat striatum were also assessed.

Toxicity of dipyridyl compounds and related compounds.

Five dipyridyl isomers, 2,2'-, 2,3'-, 2,4'-, 3,3'-, and 4,4'-dipyridyl, are products resulting from the pyrolytic degradation of tobacco products and degradation of the herbicide paraquat, and therefore may be present in the environment. In this article, the toxicological properties of these dipyridyl isomers in humans and animals are reviewed. Epidemiological studies suggest that cancerous skin lesions in workers involved in the manufacturing of paraquat may be associated with exposure to dipyridyl compounds.

Elimination of alkaloids from plant-derived human monoclonal antibody.

A human antiviral monoclonal antibody (mAb) expressed in transgenic tobacco plants was purified from the tobacco leaf by two different methods. In one method, total protein precipitated with ammonium sulfate was applied to a Hi-Trap protein A column (column method). In the second method, leaf supernatant obtained after liquid nitrogen leaf grinding was directly immunoprecipitated using protein A-agarose beads (immunoprecipitation method).
