Intracavitary Electron FLASH Radiotherapy in a Canine Cancer Patient With Oral Malignant Melanoma

PURPOSE/OBJECTIVE(S): Studies of electron FLASH radiotherapy (FLASH-RT) in companion animals are being conducted at several institutions. High energy electron beams are generally suitable for treatment of superficial cancers, but of limited use for deep-seated tumors. In this case report, the feasibility of intracavitary electron FLASH-RT is demonstrated.MATERIALS/METHODS: A canine cancer patient

Distal cholangiocarcinoma - from novel biomarkers to clinical management and outcome

Cholangiocarcinoma is an aggressive malignacy arising from the biliary tree. Anatomical subtypes ofcholangiocarcinoma differs in tumor biology and clinical management. Distal cholangiocarcinoma (dCCA)originates from the common bile duct. Radical resection is the only curative treatment, for dCCA it entails apancreatoduodenectomy (Whipple procedure). Other periampullary cancers treated with pancrea

Time-dependent evaluation of recommender systems

Evaluation of recommender systems is an actively discussed topic in the recommender system community. However, some aspects of evaluation have received little to no attention, one of them being whether evaluating recommender system algorithms with single-number metrics is sufficient. When presenting results as a single number, the only possible assumption is a stable performance over time regardle

Proposed cutoff for fetal scalp blood lactate in intrapartum fetal surveillance based on neonatal outcomes : a large prospective observational study

OBJECTIVE: Determination of lactate in fetal scalp blood (FBS) during labour has been recognised since the 1970s. The internationally accepted cutoff of >4.8 mmol/l indicating fetal acidosis is exclusive for the point-of-care device (POC) LactatePro™, which is no longer in production. The aim of this study was to establish a new cutoff for scalp lactate based on neonatal outcomes with the use of t

Circular rnas in hedgehog signaling activation and hedgehog‐mediated medulloblastoma tumors

Within the past decade, circular RNAs have largely emerged as novel regulators of human biology, including brain function and cancer development. On the other hand, the Hedgehog pathway has established roles in regulating biological processes, including tumorigenesis. Here, the circular RNA transcriptome, in the context of Hedgehog signaling activation of medulloblastoma Daoy and human embryonic p

Renal dysfunction after total knee replacement is not aggravated by bone cement

Background: Total knee replacement (TKR) has been associated with postoperative renal dysfunction. The use of monomeric methylmethacrylate (MMA) bone cement causes hypotension by several mechanisms. Methods: In 30 patients undergoing TKR with (n=16), or without (n=14) bone cement, serum levels of creatinine, cystatin C and creatine kinase (CK) and urinary levels of creatinine and markers for glome

Income tax progressivity and inflation during the world wars

This paper studies the impact of inflation on income taxes in Sweden, the UK, and the United States during the world wars. As tax reforms were rising top marginal rates and reducing exemption thresholds, extraordinary levels of inflation eroded the real value of exemptions, brackets, and deductions. The micro-simulation of actual and alternative scenarios shows that inflation made the tax less pro

Accessibility and quality of drug company disclosures of payments to healthcare professionals and organisations in 37 countries: A European policy review

Objectives: To examine the accessibility and quality of drug company payment data in Europe.Design: Comparative policy review of payment data in countries with different regulatory approaches to disclosure.Setting; 37 European countries.Participants: European Federation of Pharmaceutical Industries and Associations, its trade group and their drug company members; eurosfordocs.eu, an independent da

Cryogels with affinity ligands as tools in protein purification

Affinity chromatography is one of the well-known separation techniques especially if high purity is desired. Introducing ligands on monolithic structure gives the possibility for purifying complex media such as plasma and crude extract. This chapter is focusing on the preparation of cryogels as monolithic column and immobilization of concanavalin A on its surface as ligand for capturing the glycop

Why is a truth-predicate like a pronoun?

I begin with an exposition of the two main variants of the Prosentential Theory of Truth (PT), those of Dorothy Grover et al. and Robert Brandom. Three main types of criticisms are then put forward: (1) material criticisms to the effect that (PT) does not adequately explain the linguistic data, (2) an objection to the effect that no variant of (PT) gives a properly unified account of the various o

Charity and Error-Theoretic Nominalism

I here investigate whether there is any version of the principle of charity both strong enough to conflict with an error-theoretic version of nominalism about abstract objects (EN), and supported by the considerations adduced in favour of interpretive charity in the literature. I argue that in order to be strong enough, the principle, which I call “(Charity)”, would have to read, “For all expressi

Tuning the selective permeability of polydisperse polymer networks

We study the permeability and selectivity ('permselectivity') of model membranes made of polydisperse polymer networks for molecular penetrant transport, using coarse-grained, implicit-solvent computer simulations. In our work, permeability P is determined on the linear-response level using the solution-diffusion model, P = KDin, i.e., by calculating the equilibrium penetrant partition ratio K and

A sensitive assay for dNTPs based on long synthetic oligonucleotides, EvaGreen dye and inhibitor-resistant high-fidelity DNA polymerase

Deoxyribonucleoside triphosphates (dNTPs) are vital for the biosynthesis and repair of DNA. Their cellular concentration peaks during the S phase of the cell cycle. In non-proliferating cells, dNTP concentrations are low, making their reliable quantification from tissue samples of heterogeneous cellular composition challenging. Partly because of this, the current knowledge related to the regulatio

High methylmercury uptake by green algae in Lake Titicaca : Potential implications for remediation

Anthropogenic pressure in the high altitude lakes such as Titicaca and Uru (Bolivia) may favor the production of methylmercury (MeHg) known to accumulate in trophic chains. Periphyton associated with emerged aquatic plants (totoras) from the lake shores accumulates and demethylates MeHg providing a potential cost-effective water treatment technique. In this laboratory study, we measured the MeHg u

Fetal haemoglobin and bronchopulmonary dysplasia in neonates : An observational study

Objective: Early decrease in fetal haemoglobin (HbF) is an indicator of loss of endogenous blood components that might have predictive value for development of bronchopulmonary dysplasia (BPD). The link between HbF and BPD has not been evaluated. Design: Retrospective observational study. Setting: Tertiary level neonatal intensive care unit, referral centre for Southern Sweden. Patients: 452 very

Reclaiming constructive alignment

Constructive Alignment (CA) is neither the panacea, nor the unalloyed evil depicted in the majority of higher education discourses. But rather, the theory is a heuristic and accessible representation of commonly agreed upon aspects of modern curriculum and educational theory, designed explicitly to support learning and teaching. However, when imposed top-down for accountability purposes, or used a

Mono endo-6- And bis endo,endo-12-N,N-diethylcarbamoyl derivatives of Tröger’s Base. Synthesis and exo-endo isomerization study

An efficient synthetic route to the mono-endo-6- and bis-endo,endo-6,12-N,N-diethylcarbamoyl derivatives of Tröger’s base (TB), endo-7 and endo-8, is reported. Studies of reaction time, proton source, and additive allowed establishment of optimized conditions for the conversion of exo-7 into the corresponding isomer endo-7. With a longer reaction time, the exo,exo-6,12 bis-carbamoyl derivative exo
