Although smoking prevalence has declined in recent years, certain subpopulations continue to smoke at disproportionately high rates and show resistance to cessation treatments. Individuals showing cognitive and affective impairments, including emotional distress and deficits in attention, memory, and inhibitory control, particularly in the context of psychiatric conditions, such as attention-de...

background: histopathological diagnosis of lesions arising from the intake of tobacco is based on subjective evaluation of morphological alterations within the lesional tissue. oral exfoliative cytology is a non-invasive diagnostic technique for early detection of oral premalignant and malignant lesions. morphometric techniques have been advocated as objective and reproducible methods of detect...

the influence of salinity on the different polyamine fractions (free, conjugated, and bound) was compared in a natrophilic halophyte (beta vulgaris l. cv. ic) and a salt sensitive glycophyte (nicotiana rustica l. cv. basmas). low-level salinity (25 mm nacl) and high salinity (150 and 50 mm nacl for sugar beet and tobacco, respectively) were supplied in hydroponics. under low salinity shoot dry ...

This study experimentally tested the effects of 2 types of content commonly found in anti-tobacco television messages-content focused on communicating a health threat about tobacco use (fear) and content containing disgust-related images-on how viewers processed these messages. In a 2 x 2 within-subjects experiment, participants watched anti-tobacco television ads that varied in the amount of f...

A member of the potato proteinase inhibitor II (PPI-II) gene family under the control of the cauliflower mosaic virus 35S promoter has been introduced into tobacco (Nicotiana tabacum). Purification of the PPI-II protein that accumulates in transgenic tobacco has confirmed that the N-terminal signal sequence is removed and that the inhibitor accumulates as a protein of the expected size (21 kD)....

Image analysis based on color thresholding is the reference method for measuring severity as percent area affected. It deemed to produce accurate results, usually considered “true” value. More than a dozen applications have been used task in phytopathometry studies, but none was coded R language. Here we introduced and evaluated pliman, suite of plant images. In particular, show functions compu...

onion thrips, thrips tabaci lindeman, is a broadly distributed pest that attacks a wide range of crops. to investigate the intra-specific morphometric variation and the genetic diversity of the species in iran, four populations from tobacco plus 18 populations from onion were studied in some 17 provinces of iran. morphological analysis, using principal components and canonical discriminant anal...

Background: Both hypertension (HTN) and tobacco addiction pose a threat to the health, environment, and socioeconomic status (SES) of the people. When tobacco use disorder exists in people with HTN, it hastens the disease progress and causes early complications. The present study aimed to study the knowledge and practice of tobacco addiction in patients with HT...
