BACKGROUND Three-dimensional ultrasound (3DUS) at simulation compared to 3DUS at treatment is an image guidance option for partial breast irradiation (PBI). This study assessed if user dependence in acquiring and contouring 3DUS (operator variability) contributed to variation in seroma shifts calculated for breast IGRT. METHODS Eligible patients met breast criteria for current randomized PBI ...

Purpose: Early relationships formed between parent and child are thought to guide the child’s feelings, thoughts and expectations in subsequent adult relationships. We examined the relationship between two four category models of perceptions of parenting and adult attachment style among a nonclinical cohort. Parenting style was assessed using the Parental Bonding Instrument (PBI) and adult atta...

A new fluorescent derivative of cholesterol, N,N'-(N-(2-(3β-cholest-5-en-3yl-formamido)ethyl) pyrene-1-sulfonamido)ethyl perylene-3,4:9,10-tetracarboxylic acid bisimide (CPPBI), was designed and synthesized. In the design, pyrene (Py) and perylene bisimide (PBI) were specially chosen as the energy donor and the acceptor, respectively. Fluorescence studies revealed that (1) CPPBI shows a strong ...

In connection with the determination of serum protein-bound iodine (PBI), it is occasionally advantageous to have available reagents with a very low iodine blank. Of the reagents required in a PBI procedure employing dialysis, wet combustion with 112S04 and Cr (VI), volatilization of iodine after liberation with 113P03, and estimation of iodine by means of the Ce (IV)-As (III) reaction, the Cr ...

PURPOSE To assess toxicity and clinical outcome, in breast cancer patients treated with external beam partial breast irradiation (PBI) consisting of 35 Gy in 7 daily fractions (5 Gy/fraction). MATERIALS AND METHODS Patients affected by early-stage breast cancer were enrolled in this phase II trial. Patients had to be 60 years old or over and treated with breast conservative surgery for early ...

We present a formal approach for combining programming by demonstration (PbD) with programming by instruction (PbI)—a largely unsolved problem. Our solution is based on the integration of two successful formalisms: version space algebras and the logic programming language Golog. Version space algebras have been successfully applied to programming by demonstration. Intuitively, a version space d...

Abstract Simple reaction procedure, boiling of an equimolar mixture [Re(Cl)(CO) 3 (dppv)] (dppv— cis -1,2-bis(diphenylphosphino)-ethene), 2-(2-pyridyl)benzimidazole (pbi), and TlClO 4 in o -dichlorobenzene solution, leads to two, chromatographically separable, isomers [Re(CO) 2 (dppv)(pbi)] complex. The obtained species, the yellow-emissive [ OC -6–54] orange-emissive -6–53] isomers, have been ...

Here, we demonstrate a new approach for the synthesis of ion exchange microfibers with finely tuned anhydrous conductivity. This work presents microfluidics as a system to control the size and phosphoric acid (PA) doping level of the polybenzimidazole (PBI) microfibers. It has been shown that the PA doping level can be controlled by varying the flow ratios in the microfluidic channel. The diame...

Proximity searching consists in retrieving objects out of a database similar to a given query. Nowadays, when multimedia databases are growing up, this is an elementary task. The permutation based index (PBI) and its variants are excellent techniques to solve proximity searching in high dimensional spaces, however they have been surmountable in low dimensional ones. Another PBI’s drawback is th...

Shifting sites of blood cell production during development is common across widely divergent phyla. In zebrafish, like other vertebrates, hematopoietic development has been roughly divided into two waves, termed primitive and definitive. Primitive hematopoiesis is characterized by the generation of embryonic erythrocytes in the intermediate cell mass and a distinct population of macrophages tha...
