Long‐range transport of terrestrial particulate organic carbon to the open ocean by sediment resuspension

Limnology and Oceanography, EarlyView.
Abstract The transport of particulate organic carbon (POC) from land to deep‐sea sediments is a critical component of the global carbon cycle. However, the transport processes of terrestrial POC across continental shelves remain poorly understood due to the complexity of these systems.

Sternal nonunion on bone scintigraphy: A case report [PDF]

, 2013
Sternal non-union is a severe complication of sternotomy closure following open heart surgeries. Healing problems typically occur in 0.3% to 5% of patients. Technetium-99m methylene diphosphonate (99mTc-MDP) bone scintigraphy has been used to assess bone

The deep ocean as a major sink for terrestrial organic carbon

Limnology and Oceanography Letters, EarlyView.
Abstract Rivers transport ~200 Tg of particulate organic carbon (POC) to the global ocean annually, of which 30% is known to be buried in continental‐shelf sediments. The fate of the remaining “missing” terrestrial POC (POCterr) remains uncertain, with proposed explanations including rapid remineralization or transport to the remote deep ocean.

Self‐Assembly of Noncanonical Peptides: A New Frontier in Cancer Therapeutics and Beyond

Macromolecular Bioscience, EarlyView.
Representative examples of noncanonical peptide assemblies in anticancer therapeutics, biomaterials, regenerative medicine, molecular imaging, and catalysis are discussed, highlighting enzyme‐instructed self‐assembly as a valuable approach for constructing biomimetic and bioinspired materials that bridge the interface between biological systems and ...

Automatic bone marrow segmentation for precise [177Lu]Lu‐PSMA‐617 dosimetry

Medical Physics, EarlyView.
Abstract Background Bone marrow (BM) is the dominant dose‐limiting organ in [177Lu]Lu‐PSMA‐617 therapy for patients with metastasized castration resistant prostate cancer, where BM dosimetry is challenging due to segmentation. Purpose We aim to develop an automatic image‐based segmentation method on peri‐therapeutic sequential [177Lu]Lu‐PSMA‐617 images

Accuracy of a whole‐body single‐photon emission computed tomography with a thallium‐bromide detector: Verification via Monte Carlo simulations

Medical Physics, EarlyView.
Abstract Background Single‐photon emission computed tomography (SPECT) devices equipped with cadmium–zinc–telluride (CZT) detectors achieve high contrast resolution because of their enhanced energy resolution. Recently, thallium bromide (TlBr) has gained attention as a detector material because of its high atomic number and density.

Instantaneous in vivo distal edge verification in intensity‐modulated proton therapy by means of PET imaging

Medical Physics, EarlyView.
Abstract Background Intensity‐modulated proton therapy (IMPT) holds promise for improving outcomes in head‐and‐neck cancer (HNC) patients by enhancing organ‐at‐risk (OAR) sparing. A key challenge in IMPT is ensuring an accurate dose delivery at the distal edge of the tumor, where the steep dose gradients make treatment precision highly sensitive to ...

Reference datasets for commissioning of model‐based dose calculation algorithms for electronic brachytherapy

Medical Physics, EarlyView.
Abstract Purpose This work provides the first two clinical test cases for commissioning electronic brachytherapy (eBT) model‐based dose calculation algorithms (MBDCAs) for skin irradiation using surface applicators. Acquisition and Validation Methods The test cases utilize the INTRABEAM 30 mm surface applicator.

The 10% Rule in Sentinel Node Biopsy: Is Removal of All Threshold Nodes Necessary?

Otolaryngology–Head and Neck Surgery, EarlyView.
Abstract Objective Sentinel lymph node biopsy (SLNB) procedures have been guided by the “10% rule,” which stipulates that any lymph node (LN) with gamma probe activity (GPA) measured at 10% of the most radioactive sentinel lymph nodes (SLNs) should be excised.
