Evidence From Microscopy and U–Pb Geochronology as a Clue to the Influence of the Cretaceous Magmatism in the Diagenesis of Pre‐Salt Carbonate Reservoirs in the Santos Basin (Brazil)

Geological Journal, EarlyView.
Carbonates from Santos Basin revealed U–Pb ages correlated with basalt ages (A), suggesting that they were formed during magmatic events. These events placed hot CO2 in the reservoir, which, when mixed with carbonate‐rich cold water (B), led to thermal convection, enabling the formation of the U contained in the carbonates.

Lymph‐based liquid biopsy: Current progress and future potential

Interdisciplinary Medicine, EarlyView.
Recent evidence under the revised Starling principle indicates that lymph‐based liquid biopsies may offer superior diagnostic performance over blood‐based counterparts in certain clinical scenarios, such as early‐stage solid tumor detection. Currently, various biomarkers within the lymphatic system show significant diagnostic potential for a range of ...

Iodine-123 labeled reboxetine analogues for imaging of noradrenaline transporter in brain using single photon emission computed tomography [PDF]

, 2012
Preliminary investigation of the radioiodinated (S,S)-reboxetine analogue, 123I-INER, in baboons showed this tracer to have promise for imaging the noradrenaline transporter (NAT) using single photon emission computed tomography (SPECT).

Occupational burnout in nuclear medicine technologists working in Australia and New Zealand – results of a multi‐national survey

Journal of Medical Radiation Sciences, Volume 72, Issue 1, Page 25-33, March 2025.
Occupational burnout is associated with negative feelings about the workplace and is often caused by a high workload and a non‐supportive workplace. It is associated with absenteeism, high turnover of staff and decreased patient care. More than half of the New Zealand participants and three quarters of the Australian participants had moderate levels of

A Novel Method for Generating a Fused Ventilation–Perfusion Map Using CT‐Derived Ventilation and FDG‐PET for Lung Functional Avoidance in Radiotherapy: A Feasibility Study

Precision Radiation Oncology, EarlyView.
This study retrospectively analyzed two types of respiratory phase CT and PET/CT images of 20 lung cancer patients. After DIR and functional grading, three lung function images were developed, and their correlations and differences were evaluated. Abstract Background Pulmonary ventilation–perfusion function plays a crucial role in both radiotherapy ...
