Variations of 14-C around AD 775 and AD 1795 - due to solar activity
, 2015 The motivation for our study is the disputed cause for the strong variation of 14-C around AD 775. Our method is to compare the 14-C variation around AD 775 with other periods of strong variability.

Peptide‐Based Biomaterials as a Promising Tool for Cancer Radiotherapy
Advanced Science, EarlyView.This review provides a systematic overview of peptide‐based biomaterials in tumor radiotherapy, covering their roles as both radiosensitizers and radiopharmaceuticals. Peptide‐based radiosensitizers are generally divided into three categories: peptides as direct radiosensitizers, peptides as carriers of radiosensitizers, and targeted‐peptide‐modified ...

Who Pulled the Trigger: a Supernova or an AGB Star?
, 2010 The short-lived radioisotope $^{60}$Fe requires production in a core collapse supernova or AGB star immediately before its incorporation into the earliest solar system solids. Shock waves from a somewhat distant supernova, or a relatively nearby AGB star,

Fluorescence Guided Surgery in Gastric Cancer: What Do We Have and What Can We Do?
Annals of Gastroenterological Surgery, EarlyView.ABSTRACT Background and Objective Fluorescence imaging has emerged as a valuable adjunct in gastric surgery, enhancing resection precision and oncologic outcomes. However, the use of indocyanine green (ICG) remains controversial due to uncertainties in efficacy and administration. A lack of standardized protocols persists.

Conceptual Design Study of 13 MeV Proton Cyclotron [PDF]
, 2012 A study to determine the conceptual design of a 13 MeV proton cyclotron for PET (Positron Emission Tomography) facility has been carried out. Based on studies on reactions of PET radioisotopes production, reaction cross-sections and some design ...

Advanced NanoBiomed Research, EarlyView.A new ethoxyethanol derivative of iminofullerene, F2, is synthesized and labeled with 99mTc to produce 99mTc‐F2. In vitro, compound F2 inhibits the activation of primary mouse bone marrow‐derived macrophages stimulated with lipopolysaccharide. Moreover, 99mTc‐F2 is selectively enriched in the injured joints of mice. Inflammatory macrophages play a role

Chemistry – A European Journal, Volume 31, Issue 41, July 22, 2025.We designed and synthesized novel mannose‐6‐phosphate (M6P) derivatives to enhance their binding affinity for the CI‐M6P/IGF2 receptor, which plays a key role in lysosomal targeting. Using a fluorescence polarization assay, we evaluated di‐, tri‐, and penta‐M6P peptides and modified M6P analogs.

Chemistry – A European Journal, Volume 31, Issue 41, July 22, 2025.A double click‐strategy combining copper‐catalyzed azide‐alkyne cycloaddition with (thia‐)Diels‐Alder reactions involving a reactive s‐cis‐constrained diene is reported. Three different one‐pot protocols (i.e., sequential or three‐component reactions) are proposed and offer valuable guidance for future applications.

Drivers of dissolved organic matter processing in subterranean estuaries
Limnology and Oceanography Letters, Volume 10, Issue 4, Page 536-546, August 2025.Abstract Subterranean estuaries (i.e., seawater‐fresh groundwater mixing zones at coastal aquifers) are highly reactive boundaries between continental groundwater and coastal surface seawater. Because particulate organic matter is retained in shallow sediments, internal microbial transformations rely on dissolved organic matter (DOM) supply and ...
