Predictors of Successful Tobacco Cessation After Receiving an E-Cigarette Based Smoking Cessation Intervention.
Tob Use Insights
October 2024
Norwich Medical School, University of East Anglia, Norwich, UK.
Introduction: E-cigarettes have been shown to be effective for tobacco smoking cessation. Predicting those who are most likely to achieve smoking abstinence after receiving an e-cigarette based smoking cessation intervention could help to target interventions more efficiently.
Methods: A secondary analysis of baseline characteristics of 505 people who received an emergency department based smoking cessation intervention incorporating brief advice, provision of an e-cigarette starter kit and referral to stop smoking services.
Evidence on the ecological and physical effects of built structures in shallow, tropical coral reefs: a systematic map.
Environ Evid
May 2024
National Centers for Coastal Ocean Science, National Ocean Service, National Oceanic and Atmospheric Administration, 101 Pivers Island Road, Beaufort, NC, 28516, USA.
Article Synopsis
- Shallow tropical coral reefs are under threat from climate change, coastal development, pollution, and physical disturbances, prompting efforts to restore these ecosystems using built structures.
- Restoration practitioners are increasingly employing various types of built structures, including artificial and natural interventions, but there is a lack of synthesized evidence on their effectiveness in enhancing coral growth and survival.
- To address this knowledge gap, a systematic review was conducted to map global evidence on the performance of these built structures in shallow tropical coral ecosystems across contexts like restoration and coastal protection.
Preliminary exploration of the expression of acetylcholinesterase in normal human T lymphocytes and leukemic Jurkat T cells.

The classic enzymatic function of acetylcholinesterase (AChE) is the hydrolysis of acetylcholine (ACh) in the neuronal synapse. However, AChE is also present in nonneuronal cells such as lymphocytes. Various studies have proposed the participation of AChE in the development of cancer.

Genetics
July 2024
Genetics Graduate Interdisciplinary Program, University of Arizona, Tucson, AZ, 85721, USA.
Article Synopsis
- The primary ribosomal RNA (rRNA) genes are found in large tandem repeats across all organisms, causing instability that can affect gene copy numbers, but the specific conditions influencing this remain unclear.
- Targeted damage to the rRNA genes on the Y chromosome revealed that complete loss of rDNA results in lethal effects in Drosophila after embryogenesis, hindering larval development.
- The study also explored how the presence of retrotransposons-R1 and R2 is linked to rDNA copy number, revealing a complex relationship between X- and Y-linked rDNA and suggesting a connection between nucleolar dominance and amplification of rDNA in Drosophila.
TGF-β2 Induces Ribosome Activity, Alters Ribosome Composition and Inhibits IRES-Mediated Translation in Chondrocytes.

Alterations in cell fate are often attributed to (epigenetic) regulation of gene expression. An emerging paradigm focuses on specialized ribosomes within a cell. However, little evidence exists for the dynamic regulation of ribosome composition and function.
