Dose calculations for [¹³¹I] meta-iodobenzylguanidine-induced bystander effects

, 2014
Targeted radiotherapy is a potentially useful treatment for some cancers and may be potentiated by bystander effects. However, without estimation of absorbed dose, it is difficult to compare the effects with conventional external radiation treatment ...

Correlation between Body Mass Index and Radiation Dose Metrics in Adult Thorax and Abdomen Computed Tomography Examination: A Cross-sectional Study [PDF]

Journal of Clinical and Diagnostic Research
Introduction: Computed Tomography (CT) procedures contribute significantly to medical radiation exposure and therefore necessitate the implementation of optimisation measures that balance diagnostic image quality with patient safety. Body Mass Index (BMI)

Prediction of Dose Length Product for chest CT Examinations using Artificial Neural Networks (ANN)

, 2022
Abstract This study aimed to design an Artificial Neural Network modelling to estimate the remarkable dose length product (DLP) value during the chest computed tomography (CT) examinations for quality assurance in a retrospective, cross-sectional study.

ON THE AUTOMORPHISMS OF THE NONSPLIT CARTAN MODULAR CURVES OF PRIME LEVEL [PDF]

, 2016
We study the automorphisms of the nonsplit Cartan modular curves Xns(p) of prime level p. We prove that if p ≥ 29 all the automorphisms preserve the cusps.

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

FEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Radiation dose metrics in multidetector computed tomography examinations: A multicentre retrospective study from seven tertiary care hospitals in Kerala, South India

Indian Journal of Radiology and Imaging, 2018
Background: Presently, computed tomography (CT) is the most important source of medical radiation exposure. CT radiation doses vary considerably across institutions depending on the protocol and make of equipment.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...
