まとめ
死後生検は、感染症調査において、死検に代わる実用的で低侵襲な代替手段です。これらの生検は、研究および臨床設定でのアクセスを向上させ、効率的かつ費用対効果の高い高品質の組織サンプルを提供します。
科学分野:
- 病理学;感染症;医療診断
背景:
- 死検は感染症調査の標準であるが、アウトブレイク時のインフラ、人員、安全上の懸念などの限界に直面している。;死後超音波ガイド下生検は、必須の組織サンプリングのための低侵襲で実用的な代替手段を提供する。
研究 の 目的:
- 死後生検を、死亡したCOVID-19患者に対する従来の死検の実行可能な代替手段として評価すること。;死検と比較した死後生検の品質、実現可能性、および費用対効果を評価すること。
主な方法:
- 死亡したCOVID-19患者60例の症例シリーズを研究し、死検および超音波ガイド下生検によって108例の死後検体を採取した。;生検は死後1時間以内にベッドサイドで行われた。サンプルは、形態学的、免疫組織化学的(IHC)、および透過型電子顕微鏡(TEM)技術を使用して分析された。;臨床および疫学的データは死前に収集された。
主要な成果:
- 死後生検は、死検(180ユーロ対1500〜3000ユーロ)よりも迅速、低侵襲、かつ費用対効果が高かった。;免疫組織化学(IHC)および透過型電子顕微鏡(TEM)に適した高品質のサンプルが得られ、成功率は脾臓の67%から肝臓の100%であった。;低侵襲アプローチにより、特に完全な死検が不可能な場合に、家族の受け入れが増加した。
結論:
- 死後生検は死検の価値ある代替手段であり、アクセシビリティの向上、コストの削減、および処理速度の向上により高品質のサンプルが得られる。;その低侵襲性と主要臓器のサンプリング能力は、臨床および研究設定での実現可能性を高める。;この方法は、新興疾患の調査および死後病理の理解におけるより広範な応用をサポートする。

Post-traumatic stress disorder (PTSD) is a psychiatric condition that arises following exposure to traumatic events such as natural disasters, forced displacement, or severe accidents. It significantly impairs individuals' ability to cope with daily activities and disrupts their emotional and psychological equilibrium.
Symptoms and Behavioral Manifestations
A spectrum of distressing symptoms characterizes PTSD. Recurrent flashbacks, where individuals involuntarily relive traumatic events,...

Ultrasound I: Abdominal Ultrasonography
1.8K
Introduction:
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...

Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.

Post-translational Translocation of Proteins to the RER
7.8K
A sizable fraction of proteins destined for ER are first synthesized in the cell cytosol and then transported across the ER membrane–a process called post-translational translocation. Similar to cotranslationally translocated proteins, these proteins also use the Sec translocon complex to enter the ER lumen.
Targeting proteins to the ER
Hsp40 and Hsp70 chaperone molecules bind the translated proteins in the cytosol to prevent their folding. The chaperone binding helps to keep the signal...
