Introduction: Sri Lanka became a signatory to the WHO Frame Work Convention on Tobacco Control in September 2003, and this was ratified in November 2003. With a view to reduce the use of tobacco in Sri Lanka, the National Authority on Tobacco and Alcohol Act (NATA) No. 27 of 2006 was implemented.
Aim: To assess the behavior changes related to tobacco use among adolescents and young adults following exposure to tobacco control measures were implemented by NATA.
Materials And Methods: A case-control study was conducted on 42 adolescent (aged 13-19 years) and 156 young adult (aged 20-39 years) men living in Anuradhapura Divisional Secretary area in Sri Lanka. Cases (current quitters) and controls (current smokers) were compared to ascertain the outcome following the exposure to tobacco control measures. A self-administered questionnaire and focus group discussions were used to ascertain the exposure status in cases and controls. Confounding was controlled by stratification and randomization. Univariate analysis was performed by Backward Stepwise (Likelihood Ratio) method.
Results: Among 198 respondents, 66 (27.3% adolescents and 72.7% young adults) were quitters, while 132 smokers (18.2% adolescents and 81.8% young adults) were current smokers. Exposure to the anti-smoking media messages revealed that TV was the strongest media that motivated smokers to quit smoking. Majority (66%) of cases and control were not exposed to tobacco promotion advertisements, while 47% of the cases and 50% of the control had never seen tobacco advertisements during community events. All cases (66) as well as 89% (118) of the control had not noticed competitions or prizes sponsored by tobacco industry during last year ( P = 0.13).
Conclusion: Tobacco control measures implemented by NATA had a favorable influence on behavior change related to smoking among quitters and current smokers.

Background: Understanding based on up-to-date data on the burden of non-communicable diseases (NCDs) is limited, especially regarding how subtypes contribute to the overall NCD burden and the attributable risk factors across locations and subtypes. We aimed to report the global, regional, and national burden of NCDs, subtypes, and attributable risk factors in 2021, and trends from 1990 to 2021 by age, sex, and socio-demographic index (SDI).
Materials And Methods: We used data from the Global Burden of Disease Study 2021 to estimate the prevalence, deaths, and disability-adjusted life years (DALYs) for NCDs and subtypes, along with attributable risk factors.
Differences in the effectiveness of individual-level smoking cessation interventions by socioeconomic status.

Background: People from lower socioeconomic groups are more likely to smoke and less likely to succeed in achieving abstinence, making tobacco smoking a leading driver of health inequalities. Contextual factors affecting subpopulations may moderate the efficacy of individual-level smoking cessation interventions. It is not known whether any intervention performs differently across socioeconomically-diverse populations and contexts.

Volatile organic compounds (VOCs) produced by potential plant growth-promoting rhizobacteria (PGPR) play an important role in plant interactions. However, the mechanisms underlying this phenomenon are not well understood. Our findings show that the influence of VOCs from the PGPR strain (EXTN-1) on tobacco plant growth is dependent on the culture media used.

Introduction: Rural regions generally report higher smoking rates than urban centers, which increases the risk of tobacco related harms and consequences, and makes promoting smoking cessation in these areas a priority. Mass distribution of nicotine replacement therapy (NRT) by postal mail has been found to increase the odds of successful cessation attempts. Understanding factors that contribute to the use of NRT could help maximize this intervention's effectiveness.

Bacterial wilt caused by Ralstonia solanacearum is a devastating disease affecting a great many crops including peanut. The pathogen damages plants via secreting type Ш effector proteins (T3Es) into hosts for pathogenicity. Here, we characterized RipAU was among the most toxic effectors as ΔRipAU completely lost its pathogenicity to peanuts.
