- MRIガイド下集束超音波(MRg-FUS)は、神経疾患に対する低侵襲技術です。
- 本態性振戦に対する臨床研究は2013年に日本で開始されました。
- MRg-FUSは、集束超音波を使用して、リアルタイムMRIガイド下で精密な組織凝固を作成します。
研究 の 目的:
- 神経外科におけるMRg-FUSの進歩と課題をレビューすること。
- 本態性振戦、パーキンソン病、ジストニアの治療におけるMRg-FUSの可能性を強調すること。
- 頭蓋骨透過性と美容的側面におけるさらなる技術革新の必要性について議論すること。
主な方法:
- 1024個の超音波素子を使用して、集束音響エネルギーを供給します。
- リアルタイムMRIを使用して、連続的な温度および位置フィードバックを実現します。
- 高度なソフトウェアとフィードバックにより、頭蓋骨密度と解剖学的変動性の課題に対処します。
主要な成果:
- MRg-FUSは、従来の外科手術と比較してリスクが低く、即時の治療効果をもたらします。
- 頭蓋骨補正を含む技術的進歩により、安全性と有効性が向上しました。
- 一部の集団における頭蓋骨透過性の低下や美容上の懸念など、課題は残っています。

Gene Therapy

Gene therapy is a technique where a gene is inserted into a person’s cells to prevent or treat a serious disease. The added gene may be a healthy version of the gene that is mutated in the patient, or it could be a different gene that inactivates or compensates for the patient’s disease-causing gene. For example, in patients with severe combined immunodeficiency (SCID) due to a mutation in the gene for the enzyme adenosine deaminase, a functioning version of the gene can be...

Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Focusing of Light in the Eye
5.8K
Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...

Coping Strategies: Problem Focused
503
Coping strategies are methods people use to manage, tolerate, or reduce the effects of stressors. These strategies involve both behavioral and psychological actions to handle stressful situations. One common approach is problem-focused coping, which aims to change or eliminate the source of stress rather than merely addressing its consequences. This method involves taking direct action to resolve the issue causing stress.
For example, consider a student who struggles to understand their...
