Radiation Dose Assessment in Diagnostic Imaging Using Thermoluminescent Dosimeter-100H Dosimeters and a RANDO Phantom: Insights from Chest, Pelvic, and Skull Examinations

Journal of Medical Physics
Purpose: This study aims to evaluate radiation doses to the skin, pelvis, and skull during routine radiographic imaging procedures. Materials and Methods: Entrance skin dose (ESD) was assessed using both direct and indirect methods.

Patient-adapted organ absorbed dose and effective dose estimates in pediatric 18F-FDG positron emission tomography/computed tomography studies

BMC Medical Imaging, 2020
Background Organ absorbed doses and effective doses can be used to compare radiation exposure among medical imaging procedures, compare alternative imaging options, and guide dose optimization efforts.

L‐aspartate oxidase provides new insights into fumarate reduction in anaerobic darkness in Synechocystis sp. PCC6803

FEBS Letters, EarlyView.
Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.

In-house-developed phantoms for organ dose measurements using bovine tissues: A comparison study with CT-Expo simulation software

Journal of Radiation and Cancer Research, 2019
Background: Estimating organ dose from computed tomography (CT) procedures is still ongoing. The aim is to reduce induced cancer risk associated with over dose.

The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

FEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

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.

The ubiquitin system in normal and infected germinal center B cells

FEBS Letters, EarlyView.
The ubiquitin system plays a central role in germinal center (GC) B cells, influencing differentiation to long‐lived memory B cells. Oncogenic gammaherpesviruses gain access to memory B cells by establishing latency in GC B cells. Mapping ubiquitin mechanisms in normal and infected GC B cells will define specific molecular circuits in B cells germane ...

Modelling and reconstructing the respiratory motion of the liver [PDF]

, 2013
Respiratory organ motion is a complicating factor in tumour treatment. For dose delivery, the aim is to obtain a possibly static target in the beam's eye view whenever the beam is on.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...
