The hidden role of heterotrophic bacteria in early carbonate diagenesis.

Microbial impacts on early carbonate diagenesis, particularly the formation of Mg-carbonates at low temperatures, have long eluded scientists. Our breakthrough laboratory experiments with two species of halophilic aerobic bacteria and marine carbonate grains reveal that these bacteria created a distinctive protodolomite (disordered dolomite) rim around the grains. Scanning Electron Microscopy (SEM) and X-ray Diffraction (XRD) confirmed the protodolomite formation, while solid-state nuclear magnetic resonance (NMR) revealed bacterial interactions with carboxylated organic matter, such as extracellular polymeric substances (EPS).

Magnetic resonance-guided stereotactic body radiation therapy for pancreatic oligometastases from renal cell carcinoma.

Stereotactic body radiation therapy (SBRT) may be a non-invasive strategy to treat patients with pancreatic oligometastases from renal cell carcinoma (RCC). We analyzed 11 patients treated with MR-guided SBRT to 31 pancreatic oligometastases. At a median follow-up of 31.

Overview of the Head and Neck Tumor Segmentation for Magnetic Resonance Guided Applications (HNTS-MRG) 2024 Challenge.

Magnetic resonance (MR)-guided radiation therapy (RT) is enhancing head and neck cancer (HNC) treatment through superior soft tissue contrast and longitudinal imaging capabilities. However, manual tumor segmentation remains a significant challenge, spurring interest in artificial intelligence (AI)-driven automation. To accelerate innovation in this field, we present the Head and Neck Tumor Segmentation for MR-Guided Applications (HNTS-MRG) 2024 Challenge, a satellite event of the 27th International Conference on Medical Image Computing and Computer Assisted Intervention.

The association between tobacco and alcohol use and health outcomes in individuals living with diabetes and prediabetes in South Africa: A cross-sectional study.

Background: Smoking and alcohol misuse are lifestyle factors that can be controlled and have significant health effects. Both these factors increase the risk of developing conditions such as diabetes mellitus because they affect glucose metabolism and can interfere with blood glucose control in individuals with diabetes. Research on tobacco and alcohol use and specific health outcomes among adults with prediabetes or type 2 diabetes mellitus (T2DM) could provide valuable information leading to more efficient treatment and management of this disease.

Barriers and facilitators of healthcare professionals in integrating shared decision-making in pancreatic cancer treatment: A network approach.

Purpose: Shared decision-making (SDM) is crucial in pancreatic cancer treatment due to its choice-sensitive nature and limited prognosis. Treatment of pancreatic cancer is organized in a network approach. Several obstacles exist on different levels-patient, healthcare professional, organizational, societal-that impede integration of SDM.
