Abstract

Simple Summary: This study aimed to evaluate the outcomes and prognostic factors for multicentric lymphoma in 38 small breed dogs (weighing under 15 kg) treated with combination chemotherapy with vincristine, cyclophosphamide, doxorubicin, and prednisolone between January 2014 and May 2020. Significant factors for longer mean survival time in the complete remission group included being under 10 years old, no cardiovascular heart disease, and no prior hospitalization due to chemotherapy side effects. These results will help confirm the clinical characteristics and outcomes in small breed dogs with lymphoma and provide insights into the most effective treatments and prognosis for these animals. Lymphoma is one of the most common malignant tumors in dogs. Combination chemotherapy with vincristine, cyclophosphamide, doxorubicin, and prednisolone (CHOP) is the most effective treatment for multicentric lymphoma. Previous studies have evaluated the response of large dogs to CHOP treatment and identified prognostic factors; however, studies on small dogs are lacking. In this study, we investigated the outcomes and prognostic factors for small dogs with multicentric lymphoma treated with CHOP. The responses of patients to CHOP treatment were assessed, and 54.3% were evaluated as being in complete remission (CR), 31.4% in partial remission (PR), and 14.3% in no remission (NR). The overall response rate was 85.7%. The median survival times for CR, PR, and NR patients were 683 days (85–1496 days), 241 days (15–777 days), and 119 days (61–308 days), respectively. Among the CR patients, survival was longer under the following conditions: age under 10 years (p = 0.011), no cardiovascular heart disease (p = 0.046), and no history of hospitalization due to side effects from chemotherapy (p = 0.002). These results might help clinicians build treatment plans for multicentric lymphoma in small breed dogs. [ABSTRACT FROM AUTHOR]

27. An Enhanced Continuation Power Flow Method Using Hybrid Parameterization.

Author

Abstract

The rapid integration of renewable energy sources and the increasing complexity of modern power systems urge the development of advanced methods for ensuring power system stability. This paper presents a novel continuation power flow (CPF) method that combines two well-known parameterization techniques: natural parameterization and arc-length parameterization. The proposed hybrid approach significantly improves computational efficiency, reducing processing time by 32.76% compared to conventional methods while maintaining high accuracy. The method enables faster and more reliable stability assessments by efficiently managing the complexities and uncertainties, particularly in grids with high penetration of renewable energy.

34. Physics and computational simulations of plasma burn-through for tokamak start-up

Abstract

This thesis will discuss the fundamental process of high temperature plasma formation, consisting of the Townsend avalanche phase and the subsequent plasma burn-through phase. By means of the applied electric field, the gas is partially ionized by the avalanche process. In order for the electron temperature to increase, the remaining neutrals need to be fully ionized in the plasma burn-through phase, as radiation is the main contribution to the electron power loss. The radiated power loss can be significantly affected by impurities resulting from interaction with the plasma facing components. The parallel transport to the surrounding walls is determined by the so called connection length in the plasma. Previously, plasma burn-through was simulated with the assumptions of constant particle confinement time and impurity fraction. In the new plasma burn-through simulator, called the DYON code, the treatment of particle confinement time is improved with a transonic ambipolar model for parallel transport, by using the effective connection length determined by the magnetic field lines, and Bohm diffusion model for perpendicular transport. In addition, the dynamic evolution of impurity content is calculated in a self-consistent way, using plasma wall interaction models. The recycling of the particles at the walls is also modelled. For a specific application, the recent installation of a beryllium wall at Joint European Torus (JET) enabled to investigate the effects of plasma facing components on plasma formation and build-up of plasma current in the device. According to the JET experiments the Townsend avalanche phase was not influenced by the replacement of the wall material. However, failures during the plasma burn-through phase, that could occur with a carbon wall, are not observed with a beryllium wall. In order to obtain a deeper insight in these effects this thesis will present detailed modelling of plasma burn-through. For the first time a quantitative validation of the simulation results to experimental data is documented. The simulation results with the DYON code show consistent good agreement against JET data obtained with the carbon wall as well as the beryllium wall. According to the DYON results, the radiation barrier in a carbon wall is dominated by the carbon radiation. The radiation barrier in the beryllium wall is mainly from the deuterium radiation rather than the beryllium radiation, as far as the radiated power from other impurities (i.e. carbon, nitrogen, etc) is not significant. These issues are of crucial importance for the International Thermonuclear Experimental Reactor (ITER) where the allowable toroidal electric field for plasma formation is limited to 0.35 V/m, which is significantly lower compared to the typical loop voltage ( 1 V/m) used in the current devices. Using the validated DYON code, predictive simulations for ITER are given, showing a need for RF heating to allow reliable plasma burn-through.

Abstract

Background: Currently, there is no clearly established therapy to treat mild cognitive impairment (MCI); consequently, alternative therapies, such as acupuncture, have been attempted. In many clinical studies, the potential benefits of acupuncture for cognitive improvement have been identified in clinical outcomes; however, the mechanism remains unclear. Accordingly, this study aims to investigate the therapeutic mechanism of acupuncture therapy using functional near-infrared spectroscopy and its feasibility in treating individuals with impaired cognitive function. Methods: This study is designed to be a prospective, two-arm, parallel clinical trial involving 24 participants. The patient group will be treated with acupuncture twice per week for 12 weeks; meanwhile, the healthy control group will not undergo acupuncture treatment. Functional near-infrared spectroscopy assessment and a working memory test will be performed at baseline and every 6 weeks to investigate the therapeutic mechanism of acupuncture. The primary outcome will be measured using the Korean version of the Montreal Cognitive Assessment. The secondary outcomes will be the Alzheimer's Disease Assessment Scale-cognitive subscale score, working memory task accuracy, response rate, response time, and hemodynamic response of the prefrontal lobe. The outcomes will be evaluated at baseline, and at 6 and 12 weeks after subject allocation. Discussion: This clinical pilot trial is designed to determine the feasibility of acupuncture as an effective and safe treatment for improving cognitive function in patients with MCI. Results of this study may provide guidance for future larger-scale clinical trials. Trial registration: Clinical Research Information Service (CRIS), Republic of Korea: KCT0002451.
