Novel Benzimidazole-Endowed Chalcones as α-Glucosidase and α-Amylase Inhibitors: An Insight into Structural and Computational Studies.

In search of novel antidiabetic agents, we synthesized a new series of chalcones with benzimidazole scaffolds by an efficient 'one-pot' nitro reductive cyclization method and evaluated their α-glucosidase and α-amylase inhibition studies. The 'one-pot' nitro reductive cyclization method offered a simple route for the preparation of benzimidazoles with excellent yield and higher purity compared to the other conventional acid- or base-catalyzed cyclization methods. H, C NMR, IR, and mass spectrum data were used to characterize the compounds.

Structural Quality Indicators in Radiation Oncology: Insights and Implications.

Aims: Over the past two decades, significant progress has been made in the development of quality indicators (QIs) within the field of radiotherapy (RT). However, most of the literature has predominantly focused on process and outcome-related QIs, with limited attention given to structural QIs. This review aims to address this gap by providing insights into structural QIs in RT and examining the complexities and considerations involved in establishing universal standards for these indicators across RT facilities globally.

Moving towards process-based radiotherapy quality assurance using statistical process control.

Monitoring Radiotherapy Quality Assurance (QA) using Statistical Process Control (SPC) methods has gained wide acceptance. The significance of understanding the SPC methodologies has increased among the medical physics community with the release of Task Group (TG) reports from the American Association of Physicists in Medicine (AAPM) on patient-specific QA (PSQA) (TG-218) and Proton therapy QA (TG-224). Even though these reports recommend using SPC for QA analysis, physicists have ambiguities and doubts in choosing proper SPC tools and methodologies.

Experimental determination of thermal neutron fluence around Elekta Versa HD linear accelerator for various photon energies.

A complex neutron spectrum generated along with a useful photon beam imposes an additional radiation protection risk around medical linear accelerators (linac). The thermal neutron component of this complex neutron spectrum formed during different photon modes of operation of Elekta Versa HD linac has been quantified using Indium foil activation technique. The thermal neutron fluence (Φ ) at isocenter for 15 MV, 10 MV and 10 MV FFF beams was found to be 2.
