Pesticide exposure is associated with deleterious health effects. Prior studies suggest Latino farmworkers perceive little control over their occupational health. Using the Health Belief Model as a theoretical guide, we explored the perceptions of Latino farmworkers working in tobacco in North Carolina (n = 72) about benefits and facilitators of pesticide protective behaviors as well as barriers, and strategies to overcome barriers to their use. Interviews were conducted with participants at farmworker housing during non-work time...

Ascorbate oxidase (AO) plays an important role in cell growth through the modulation of reduction/oxidation (redox) control of the apoplast. Here, a cotton (Gossypium hirsutum) apoplastic ascorbate oxidase gene (GhAO1) was obtained from fast elongating fiber tissues. GhAO1 belongs to the multicopper oxidase (MCO) family and includes a signal peptide and several transmembrane regions. Analyses of quantitative real-time polymerase chain reaction (QRT-PCR) and enzyme activity showed that GhAO1 was expressed abundantly in 15-day post-anthesis (dpa) wild-type (WT) fibers in comparison with fuzzless-lintless (fl) mutant ovules...

While the effectiveness of substance use prevention programs such as the Strengthening Families Program 10-14 (SFP) has been demonstrated in the USA, European SFP adaptations have not replicated these sizable effects. Following the rationale of the risk moderation hypothesis positing that elevated risk groups may benefit more from a preventive intervention than lower-risk groups, we reanalyzed evaluation data from a randomized controlled trial testing the adapted German version of SFP (SFP-D). We hypothesized a differential impact of risk status on intervention results...

This study is an assessment of the influence of parent's tobacco use on prospective tobacco use trajectories among young offspring. The study is based on unit level data from District Level Household and Facility Survey-4 (2012-2013) comprising 27,706 youths in 15-24 years' age group from northeastern states of India and used multilevel regression to identify the potential risk factors of tobacco consumption. The likelihood of using tobacco was found to be 3.4 and 1.14 times more, respectively, for the youths coresiding with mothers who use tobacco and fathers who use tobacco, in comparison to youths staying with parents not taking tobacco...

Anthocyanins are responsible for the different colors of ornamental plants. Grape hyacinth (Muscari armeniacum), a monocot plant with bulbous flowers, is popular for its fascinating blue color. In the present study, we functionally characterized an R2R3-MYB transcription factor gene MaAN2 from M. armeniacum. Our results indicated that MaAN2 participates in controlling anthocyanin biosynthesis. Sequence alignment and phylogenetic analysis suggested that MaAN2 belonged to the R2R3-MYB family AN2 subgroup. The anthocyanin accumulation of grape hyacinth flowers was positively correlated with the expression of MaAN2...

BACKGROUND: Nicotine and cigarette smoking (CS) are associated with addiction behavior, drug-seeking, and abuse. However, the mechanisms that mediate this association especially, the role of brain-derived neurotrophic factor (BDNF), dopamine (DA), and nuclear factor erythroid 2-related factor 2 (Nrf2) signaling in the cerebral cortex, are not fully known. Therefore, we hypothesized that overexpression of BDNF and DA, and suppression of Nrf2 contribute to several pathological and behavioral alterations in adult cerebral cortex...

Human vitronectin (hVN) is a glycoprotein that functions as a cell adhesion molecule and a regulator of coagulation in blood plasma and the extracellular matrix. In vitro, hVN is added to serum-free media in order to promote the adhesion of animal cells to tissue culture surfaces and the proliferation of undifferentiated stem cells. Here, we report the production of hVN in Nicotiana benthamiana using the inducible In Plant Activation (INPACT) hyper-expression platform. N. benthamiana plants were transformed with an INPACT expression cassette encoding hVN, and both the Tobacco yellow dwarf virus Rep/RepA activator and Tomato bushy stunt virus p19 gene under the transcriptional control of the ethanol-inducible AlcR:alcA gene switch...

Entomopathogenic nematodes in the Heterorhabditis genus and their symbiotic Photorhabdus bacteria are important biocontrol agents of insect pests and models for the study of microbe-host interactions. In this work, we used larvae of the tobacco budworm (Heliothis virescens) as a model to study its defensive mechanisms against Heterorhabditis bacteriophora nematodes carrying symbiotic Photorhabdus temperata. We first determined time points of initial nematode entry and release of bacteria into the haemolymph to perform transcriptional analysis of insect gene expression during these steps in the infective process...

Circulating miRNAs have shown great promises as non-invasive diagnostic and predictive biomarkers in several solid tumors. While the miRNA profiles of renal tumors have been extensively explored, knowledge of their circulating counterparts is limited. Our study aimed to provide a large-scale genome-wide profiling of plasma circulating miRNA in clear-cell renal cell carcinoma (ccRCC). Plasma samples from 94 ccRCC cases and 100 controls were screened for 754 circulating micro-RNAs (miRNA) by TaqMan arrays. Analyses including known risk factors for renal cancer, namely age, sex, hypertension, obesity, diabetes, tobacco smoking and alcohol consumption, highlighted that circulating miRNA profiles were tightly correlated with the stage of the disease...

OBJECTIVES: Messages from organizations with high, compared to low, credibility may be more persuasive. Whereas the tobacco industry has long recognized the importance of credibility in promoting its messages and public image, the source credibility of key tobacco control organizations has gone largely unmeasured. To assess credibility of a key tobacco regulator, we developed a scale of the US Food and Drug Administration (FDA) tobacco-related credibility. METHODS: We developed and tested 30 items reflective of the dimensions of source credibility (trust, expertise, and public interest) and FDA's tobacco regulatory roles in a sample of 1353 US adults and assessed reliability and validity...

Urease from Canavalia ensiformis seeds was the first enzyme ever to be crystallized, in 1926. These proteins, found in plants, bacteria and fungi, present different biological properties including catalytic hydrolysis of urea, and also enzyme-independent activities, such as induction of exocytosis, pro-inflammatory effects, neurotoxicity, antifungal and insecticidal properties. Urease is toxic to insects and fungi per se but part of this toxicity relies on an internal peptide (~11 kDa), which is released upon digestion of the protein by insect enzymes...

Lung malignancy is the foremost cause of cancer-related deaths globally and is frequently related to long-term tobacco smoking. Recent studies reveal that the expression of matrix metalloproteinases (MMPs) is extremely high in lung tumors compared to non-malignant lung tissue. MMPs are zinc-dependent proteases and are involved in the degradation of extracellular matrix (ECM). Several investigations have shown that MMPs manipulate the activity of non-ECM molecules, including cytokines, growth factors and receptors which control the tumor microenvironment...

Background: Despite efforts to reduce disadvantages across society, widening health disparities have been observed in Minnesota. This research examined whether observed declines in state-wide smoking prevalence were experienced equally by all adults with varying educational attainment. Methods: Serial cross-sectional data from the 2003, 2007, 2010 and 2014 Minnesota Adult Tobacco Survey (MATS) were analyzed. Weighted regression analyses for smoking status, time to first cigarette, cigarettes per day and non-cigarette other tobacco products (OTP) were conducted across education levels...

We assessed compliance of waterpipe product packaging and labelling with the Framework Convention on Tobacco Control's Article 11. We evaluated samples collected at a trade fair against ten domains: health warning location, size, use of pictorials, use of colour, and packaging information on constituents and emissions. We also evaluated waterpipe accessories (e.g., charcoal) for misleading claims. Ten of 15 tobacco products had health warnings on their principal display areas, covering a median of 22.4 per cent (interquartile range 19...
