A mounting body of evidence in cancer research suggests that the local microenvironment tumor cells has a profound influence on progression and metastasis. In vitro studies its pharmacological modulation, however, are often hampered by technical challenges associated with creating physiological cell culture environments integrate key components their native niche such as neighboring extracellular matrix (ECM) to mimic complex microarchitecture cancerous tissue. Using early-stage breast model...
Both cytokinin (N6-benzyladenine [BA]) and auxin (2,4-dichlorophenoxyacetic acid [2,4-D]) stimulate the accumulation of an mRNA, represented by cDNA pLS216, in Nicotiana plumbaginifolia suspension culture cells. The kinetics RNA were different for two hormones; however, response to both was transient, magnitude dose dependent. Runoff transcription experiments demonstrated that transient appearance could be accounted feedback regulation not induction degradation system. mechanism appeared...
Purpose: To determine the value of dual-energy (DE) scanning with virtual noncontrast (VNC) images and iodine maps in evaluation therapeutic response to radiofrequency ablation (RFA) for hepatic tumors. Materials Methods: A total 75 patients tumors who underwent DE computed tomography (CT) after RFA, were enrolled this study. Our CT protocol included precontrast, arterial, portal phase scans. VNC created from 80 140 kVp during arterial phases. then compared true, (TNC) images, linearly...
In this paper, a frequency tunable, high-efficiency power oscillator using Gallium Nitride High Electron Mobility Transistor (GaN HEMT) for the RF source applications is designed and fabricated. The steady state oscillation occurs in delay line feedback loop which length adjusted to tune frequency. A harmonic-tuned matching network technique employed obtain high conversion efficiency characteristic of oscillator. measured output fabricated are 44.63±0.2 dBm better than 62%, respectively,...
Pet food has recently been in the spotlight as an auxiliary approach to manage oral health, since it helps dogs or cats take relatively simple care of their mouths at home. Especially, dental hygiene chew is crucial remove teeth accumulation plaque by chemical mechanical methods. This study applied 3D printing chews, which should be tailored dogs' individual tooth structure and preferences. The optimum methods for making chews based on corn starch with glycerin extrusion-based were...
Electrical cardioversion (ECV) a widely utilized intervention for persistent atrial fibrillation (AF) aimed at restoring sinus rhythm. However, ECV can be ineffective, raising questions about subsequent treatment options. This study to compare the outcomes of non-ablation therapy versus ablation following unsuccessful ECV. A total 125 consecutive patients with AF who underwent between November 2017 and August 2023 was included in this retrospective analysis. Of these, 51.2% received only...
본 연구에서는 비육후기 Duroc 품종 돼지를 대상으로 저수준의 lysine 사료에 합성 L-leucine 첨가수준이 생산성, 도체 및 육질 특성에 미치는 영향을 평가하였다. 시험동물은 평균 74±1kg의 54두를 각 처리 당 6반복, 반복 3두씩 공시하였다. 시험사료는 0.45%의 기초사료에 L-leucine을 각각 0% (CON), 1.5% (LEU 1.5) 3.0% 3.0) 첨가한 후 30일간 급여하였다.일당증체량, 사료섭취량 사료요구율은 처리구간에 유의적인 차이를 보이지 않았다. 도체특성에 있어서는 도체율 등지방두께는 처리구 간 않았으나, 등심단면적은 L-leucine의 높아짐에 따라 증가하는 경향을 나타내었다. 근내지방도는 첨가구가 대조구에 비하여 유의적으로 높았다(P<0.05). 특성에서 조지방 함량이 차이는 없었지만 첨가에 나타내었으며, CIE L*는 증가하였다(P<0.05). The objective of this study was to investigate...
We have studied a combiner that can withstand high power while minimizing insertion loss in frequency band. In particularly, because the output be per unit elements is much lower Ku band and above than low , it necessary to combine many semiconductor order make SSPA. A planar such as microstrip, number of combined increases, increases proportionally, resulting reduction overall system efficiency an increase heating value also. The also some problems due handling rate. To improve these...
Abstract Background: Wearable types of gait-assist robots have been developed to provide additional advantages such as being easily transportable, producing a more natural gait pattern, and simple control. The purpose this study was investigate the effect intensive training with newly wearable hip-assist robot on function cardiopulmonary metabolic energy efficiency in community-dwelling elderly adults. Methods: Total 27 adults age-related problems completed intervention (15 experimental...
This study was conducted to explore a new method for imparting hydrophobicity cellulose nanofiber (CNF) using rosin sizing agent. Anionic CNF made from hardwood bleached kraft pulp by micro-grinding; this anionic then used prepare cationic through quaternization. The hydrophobization of CNFs performed adding the agent and CNFs. zeta-potentials were measured identify adsorption rate in films containing rosin-sizing contact angle, FT-IR spectra burst strength analyzed after heat treatment cure...
