The Rich Chemistry of Cyclotriveratrylene (CTV) And CT-Inspired Reactions: Anthracenes with Organic Light-Emitting Diode (OLED) Applications and the Discovery of Cascade Reactions
<p>Cyclotriveratrylene (CTV) is a supramolecular scaffold with applications in host-guest chemistry, analytical detection, drug delivery and liquid crystals. We have discovered that CTV rearranges to a highly functionalized anthracene derivative that is ideal for the synthesis of 9,10-disubstituted …

Molecular Characterization of Citrus Tristeza Virus Isolates in Commercial Citrus Grown in Belize
Isolates of Citrus Tristeza Virus (CTV) in Belize may be causing inverse stem pitting, stunting, and slow decline on sweet and sour orange rootstock combination on field trees. One isolate on Cleopatra mandarin rootstock expressed no field symptoms but may be a possible source of a detrimental …

New Cyclophanes as Supramolecular Scaffolds: The Synthesis of Tribenzo-1,4,7-Triazacyclononatriene.
… crown-shaped molecule cyclotriveratrylene (CTV). CTV has been studied extensively for its capability of binding a number of smaller organic and organometallic guests within its bowl-shaped cleft and has been used as a building block enabling the construction of more complex cryptophanes. The …

CHARACTERIZATION OF BREAST RT TREATMENT BY MULTI-INSTITUTIONAL AI-KNOWLEDGE-BASED PLANNING OPTIMIZATION MODELS
… First, an automatic segmentation model of the CTV was developed using a U-Net neural network on the MIKAPOCo dataset, achieving good agreement among the centers, comparable to manual inter-variability. Then dose prediction was conducted elegantly, treating isodoses as structures and using the …

Feasibility of Using Stereotactic Body Radiation as an Alternative to HDR for Treatment of Cervical Cancers
… were used to define a Clinical Target Volume (CTV), with a prescription of 3250 cGy to the CTV over 5 fractions. Planning started with 33 equally spaced non-coplanar beams. Beam weight optimization was used to choose the most effective beam orientations. An SBRT plan was generated using …

Treatment Planning Automation For Rectal Cancer Radiotherapy
… we used deep learning models to segment CTV and OARs and automated the inverse planning process, based on a RapidPlan model. The end-to-end process requires only the GTV contour and a CT scan as inputs. Specifically, the segmentation models could auto-segment CTV, bowel bag, large bowel, …

Adaptive Radiation Therapy Of Prostate Cancer
… cancer patients were selected for the study. The CTV included prostate and 1cm proximal seminal vesicle. PTV was created by adding 1 cm margin to CTV except 6 mm posteriorly to limit rectal dose. The treatment plans were 7 to 9 fields IMRT. CBCT was acquired before each treatment for online image …

Development of A Beam-Specific Planning Target Volume and A Robust Plan Analysis to ol For Proton Therapy
… expanding a clinical target volume (CTV) to a planning target volume (PTV). However, a PTV alone cannot adequately account for range uncertainties coupled to misaligned patient anatomy in the beam path since it does not account for the change in tissue density. In order to remedy this …

Analysis of 3D and 4D proton treatment planning for hepatic tumors
… correlation with clinical target volume (CTV) (as fraction of liver volume) is much weaker ([tau]-0.31 for 4D/3D, [tau]=0.26 for ungated/gated). There was no evidence that the tumor position within the liver influenced the [Delta]EUD. This study suggests that physicians should consider 4D …
