Color‐Pure Organic Luminophores: Characteristics, Definitions, Physical Basis and Fundamental Design Principles

Angewandte Chemie, EarlyView.
Color‐pure all‐organic emitters, i.e., with narrow spectral characteristics, are intensively studied for high‐definition organic LEDs and multi‐color bioimaging. In order to guide targeted materials design, this educative review discusses spectral characteristics, proper definitions and units, and the physical basis of spectral broadening, to distill ...

Radiation‐Induced Tumor‐Intrinsic LTβR N‐Glycosylation Suppresses Pyroptosis Through TRIM28‐Mediated PCBP2 SUMOylation to Promote Gastric Cancer Radioresistance

Advanced Science, EarlyView.
Radiotherapy triggers LTβR N‐glycosylation, enhancing its overall protein stability and nuclear retention. This accumulation drives TRIM28‐mediated PCBP2 SUMOylation, suppressing pyroptosis and conferring gastric cancer radioresistance. Therapeutically, a targeted nanoplatform (cRGD‐Lipo@EMD) effectively disrupts this regulatory axis, offering a highly

Use of snus, its association with smoking and alcohol consumption, and related attitudes among adolescents: the Finnish National School Health Promotion Study

, 2015
Background The relationship between the use of snus and lifestyle-related habits – especially in adolescence, when these behaviours begin and become established – is not widely studied.

Factors predicting willingness to quit snus and cigarette use among young males

Scientific Reports, 2023
The health hazards of smoking are well recognised and recently knowledge about the harmful effects of nicotine and snus is accumulating. We investigated the factors increasing the willingness of young Finnish males to quit snus and cigarette smoking.

Assessing tobacco use in Swedish young adults from self-report and urinary cotinine: a validation study using the BAMSE birth cohort

BMJ Open, 2023
Objectives Studies on health effects of tobacco often rely on self-reported exposure data, which is subjective and can lead to misclassification. The aim of this study was to describe the prevalence of cigarette smoking, snus and e-cigarette use, as well

Neuron‐Derived MIF Engages VCAM1 to Fuel a Self‐Amplifying CXCL8 Loop That Drives Perineural Invasion and Metastasis in Gastric Cancer

Advanced Science, EarlyView.
Neuron‐derived MIF binds VCAM1 on gastric cancer cells and activates ERK/STAT3 signaling, leading to CXCL8 transcription and secretion. Tumor‐derived CXCL8 subsequently stimulates neuronal CXCR2 to enhance MIF production, establishing a self‐amplifying MIF–VCAM1–CXCL8 positive‐feedback loop that promotes perineural invasion, tumor progression, and ...

Snus- og røykeslutt på stand virker det? [PDF]

, 2010
Samfunnet vil ikke at unge mennesker skal røyke eller bruke snus. Hvilken virkning kan det ha å gjennomføre stand i fellesarenaene på videregående skoler hvor erfarne veiledere står klare til å samtale med elevene som passerer om tobakk og snus?

Fully Programmable Slow Light Based on a Spinor Representation of Generalized Coupled‐Resonator‐Induced Transparency

Advanced Science, EarlyView.
A programmable coupled‐resonator‐induced transparency (CRIT) platform is proposed, generalizing classical electromagnetically induced transparency (EIT) via a spinor representation. By utilizing dual‐channel gauge fields and universal unitary operations, this architecture enables dynamically engineered, reconfigurable slow‐light bands on a silicon ...

Harm perception among Swedish daily smokers regarding nicotine, NRT-products and Swedish Snus

, 2010
Background In Sweden NRT-products and Snus, are easily available and used as smoking cessation aids. However, most quit attempts are made without any cessation aids. The limited use of these products as cessation aids may be influenced by the way smokers

Emotional attachment to personal tobacco packages might affect quitting behaviour. Results from a cross-sectional survey among tobacco users

Tobacco Induced Diseases, 2018
Background Emotional attachment to your brand of cigarettes or snus might imply a lower tendency to want to quit smoking or using snus. Aim: Investigate emotional attachment to the personal snus or cigarette pack, and its potential effect on ...
