まとめ
再発または難治性リンパ腫患者は、原発性リンパ腫患者と比較して、異なる腸内細菌叢と代謝プロファイルを示す。これらの腸内細菌叢とメタボロームの変動は、リンパ腫治療のための新しい治療標的を提供する可能性がある。
科学分野:
- マイクロバイオーム研究、メタボロミクス、腫瘍学
背景:
- 再発または難治性リンパ腫(R/RL)は、重大な治療上の課題をもたらす。R/RLにおける腸内細菌叢とメタボロームの理解は、新しい治療戦略の特定のために不可欠である。
研究 の 目的:
- R/RL患者と原発性、治療未治療のリンパ腫(PL)患者の間で、腸内細菌叢組成と代謝プロファイルの違いを調査すること。これらの違いに基づいてR/RLの潜在的な治療標的を探索すること。
主な方法:
- 16S rDNAシーケンスを用いた糞便微生物叢解析。差次的発現代謝物の同定のための非標的メタボロミクス。R/RL(n=14)およびPL(n=7)コホート間の腸内細菌叢および代謝物プロファイルの比較。
主要な成果:
- R/RL患者では腸内細菌叢の変化が認められ、ActinobacteriotaとAlphaproteobacteriaが増加し、Erysipelotrichales、Morganellaceae、Faecalibacterium、Clostridium、Klebsiella、Ruminococcusが減少した。アミノ酸やUDP-N-アセチルグルコサミンを含む7つの代謝物がR/RL群で有意に上方制御された。KEGGパスウェイ解析により、R/RLにおける中心炭素代謝とアミノ酸代謝の亢進が示唆された。
結論:
- 腸内細菌叢と代謝の変化は、R/RLの病態生理と関連している。糞便微生物移植などを介した腸内細菌叢の調節は、R/RL患者の腸内免疫微小環境を改善する可能性がある。これらの仮説生成的な発見には、さらなる大規模な検証が必要である。

Alterations in Respiration II
1.8K
There are numerous types of normal and abnormal respiration. Based on ventilatory movements, breathing patterns are classified as regular, deep, or shallow. Examples include Biot's breathing, Cheyne-Stokes respiration, Kussmaul's breathing, hyperventilation, and hypoventilation. Each pattern is clinically significant and aids in evaluating patients.
In Biot's breathing, the respiratory rate and depth are irregular, alternating between periods of deep gasping and apnea. Common causes...

Altered States of Awareness
1.1K
Altered states of consciousness represent significant deviations from one's normal mental state. These deviations can range from subtle changes in awareness to profound transformations in perception, thought processes, and sensory experiences. Altered states of consciousness can be triggered by various factors, including drug use, meditation, hypnosis, illness, or even intense fatigue.

Alterations in Blood Pressure
2.2K
Alterations in blood pressure, such as hypertension (high blood pressure) and hypotension (low blood pressure), significantly affect human health. Understanding these conditions' classifications, causes, and symptoms is essential for effective management and treatment.
Hypertension (High blood pressure)
Hypertension occurs when blood pressure readings consistently exceed the normal range. It is diagnosed when systolic blood pressure (the top number, indicating pressure while the heart...

Ribosome Profiling
4.2K
Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.

Carbohydrate Metabolism
14.2K
Carbohydrates are polymers composed of molecules containing atoms of carbon, hydrogen and oxygen. One gram of carbohydrate can provide four kilo-calories of energy, which makes it the most efficient instant energy source.
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...
