Screening for lung cancer: A systematic review of overdiagnosis and its implications

Molecular Oncology, EarlyView.
Low‐dose computed tomography (CT) screening for lung cancer may increase overdiagnosis compared to no screening, though the risk is likely low versus chest X‐ray. Our review of 8 trials (84 660 participants) shows added costs. Further research with strict adherence to modern nodule management strategies may help determine the extent to which ...

Structure-property relationships of photofunctional diiridium(II) complexes with tetracationic charge and an unsupported Ir–Ir bond

Communications Chemistry, 2022
In contrast to the extensively studied dirhodium(II) complexes and iridium(III) complexes, neutral or dicationic dinuclear iridium(II) complexes with an unsupported ligand are underdeveloped.

A Single-Atom Iridium Heterogeneous Catalyst in Oxygen Reduction Reaction.

Angewandte Chemie, 2019
Combining the advantages of homogeneous and heterogeneous catalysts, single-atom catalysts (SACs) are bringing new opportunities to revolutionize ORR catalysis in terms of cost, activity and durability.

Gold and palladium as indicators of an extraterrestrial component in the Cetaceous/Tertiary boundary layer at Woodside Creek and Chancet Quarry, Marlborough, New Zealand : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Earth Sciences at Massey University [PDF]

, 1998
It is widely believed that a large meteorite approximately 10 km in diameter impacted Earth at the termination of the Cretaceous Period with cosmic velocity, vaporising itself, along with a greater mass of the terrestrial target rocks into a cloud of hot

Highly active iridium(I) complexes for the selective hydrogenation of carbon-carbon multiple bonds [PDF]

, 2011
New iridium(I) complexes, bearing a bulky NHC/phosphine ligand combination, have been established as extremely efficient hydrogenation catalysts that can be used at low catalyst loadings, and are compatible with functional groups which are often ...

Transcriptional network analysis of PTEN‐protein‐deficient prostate tumors reveals robust stromal reprogramming and signs of senescent paracrine communication

Molecular Oncology, EarlyView.
Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...

Formation of nanostructured iridium and polycluster diamond films [PDF]

Tekhnologiya i Konstruirovanie v Elektronnoi Apparature, 2007
Iridium films and layered structures "iridium — diamond" were formed on Al2O3, MgO and SrTiO3 substrates. Iridium films were obtained by magnetron sputtering, and polycluster diamond films — by microwave discharge method. Structure of iridium and diamond

Globally distributed iridium layer preserved within the Chicxulub impact structure

Science Advances, 2021
The preservation of the iridium-rich layer within the Chicxulub crater captures the timing of the K-Pg boundary events. The Cretaceous-Paleogene (K-Pg) mass extinction is marked globally by elevated concentrations of iridium, emplaced by a hypervelocity ...

Resonant Inelastic X-ray Scattering on Spin-Orbit Coupled Insulating Iridates

, 2010
We determine how the elementary excitations of iridium-oxide materials, which are dominated by a strong relativistic spin-orbit coupling, appear in Resonant Inelastic X-ray Scattering (RIXS). Whereas the RIXS spectral weight at the L2 x-ray edge vanishes,
