Background: Intrahepatic cholangiocarcinoma (ICC) presents a significant clinical challenge due to its high fatality rate and limited surgical candidacy. With only 30-40% of patients eligible for surgery upon diagnosis, alternative therapies are imperative. This study assesses the efficacy of Yttrium-90 (Y-90) radioembolization for unresectable ICC patients in a non-university tertiary care center (NUTCC).

Vitamin D is essential for cattle and can be synthesized in the skin under ultraviolet irradiation. This study investigated the effects of narrow-band UV-B irradiation during automatic milking on blood vitamin D concentration and the influence of hair and black skin areas on cutaneous vitamin D synthesis in Holstein Friesian cows. Fifty-one cows were stratified by milk yield, days after calving, and percentage of black skin, then divided into three groups: shaved and irradiated (80 J/m), unshaved and irradiated (129-305 J/m), and a control group.

The radiation exposure to bystanders from nuclear medicine patients is a common concern raised in nuclear medicine departments. The GATE (Geant4 Application for Tomographic Emission) Monte Carlo radiation transport application was used to estimate the dose to a bystander. Two voxelised phantoms were utilised in a GATE Monte Carlo simulation as the radiation source and target.

The heat shock protein 90 (Hsp90) family of molecular chaperones mediates the folding and activation of ~ 400 client proteins, many of which contribute to oncogenesis. As a result, Hsp90 pan-inhibitors, which inhibit all four Hsp90 isoforms, have been investigated in the clinic for the treatment of cancer. Unfortunately, detrimental side effects were observed and hindered the clinical development of pan-Hsp90 inhibitors.

Background And Purpose: The SOFT (Stereotactic ablative radiotherapy of infra-diaphragmatic sOFT tissue metastases) trial assesses the safety and efficacy of risk-adapted MR-guided stereotactic ablative radiotherapy (SABR) of infra-diaphragmatic soft tissue metastasis in patients with oligometastatic disease (OMD) (clinicaltrials.gov ID NCT04407897). This paper reports the one-year efficacy analysis and evaluates associations between local control (LC) and clinical and dosimetric parameters.
