Evaluation of GeneXpert MTB/Rif Ultra assay performance on formalin-fixed paraffin-embedded tissues for detection.

We evaluated the Xpert MTB/Rif Ultra assay performance for (MTB) detection in formalin-fixed paraffin-embedded tissue (FFPET) compared to mycobacterial culture or laboratory-developed MTB PCR test (LDT). FFPET samples with histological features suggestive of tuberculosis from 2018 to 2023 were selected. Five hundred microlitres of tissue lysis buffer was added to FFPET scrolls and incubated at 75 °C for 5 min.

Advocacy counterstrategies to tobacco industry interference in policymaking: a scoping review of peer-reviewed literature.

Background: There has been remarkable tobacco control progress in many places around the globe. Tobacco industry interference (TII) has been identified as the most significant barrier to further implementation of the World Health Organization Framework Convention on Tobacco Control (WHO FCTC). Civil society has been recognised as a key actor in countering TII.

Tobacco industry messaging around harm: Narrative framing in PMI and BAT press releases and annual reports 2011 to 2021.

Influencing public perception is a key way in which all transnational corporations (TNCs) maintain market dominance and political power. Transnational tobacco companies (TTCs) have a long history of leveraging narratives to serve commercial ambitions. The global reach of these companies' narratives has been highlighted as a challenge in combatting public health problems caused by tobacco.

Understanding the long-term policy influence strategies of the tobacco industry: two contemporary case studies.

Objective: This paper explores transnational tobacco companies' (TTCs) long-term policy influence strategies using two case studies, harm reduction and illicit tobacco, to identify lessons for the tobacco control movement and wider efforts to address the commercial determinants of health.

Methods: Evidence from a broad combination of sources including leaked documents and findings from over two decades of TTC monitoring were reviewed for each case study and categorised using the Policy Dystopia Model, focusing on the primary discursive strategy and key instrumental (action-based) strategies used.

Results: In both case studies, TTCs seek to advance their interests by engaging primarily in reputation management, coalition management and information management strategies over the long-term to propagate their over-riding discursive strategy-'we've changed, we are part of the solution'-despite clear evidence from both case studies that this is not the case.

Room temperature atomic frequency comb storage for light.

We demonstrate coherent storage and retrieval of pulsed light using the atomic frequency comb protocol in a room temperature alkali vapor. We utilize velocity-selective optical pumping to prepare multiple velocity classes in the =4 hyperfine ground state of cesium. The frequency spacing of the classes is chosen to coincide with the =4-=5 hyperfine splitting of the 6 excited state, resulting in a broadband periodic absorbing structure consisting of two usually Doppler-broadened optical transitions.
