まとめ
Post-COVID-19は小線維ニューロパチー(SFN)を引き起こし、神経障害および自律神経症状を呈することがある。多肢的な非侵襲的電気診断検査は、罹患した個人におけるこれらの症状の評価に役立つ。
科学分野:
- 神経学
- 免疫学
背景:
- Post-COVID-19は、多様な神経障害および自律神経症状を呈する。
- これらの症状は小線維ニューロパチー(SFN)を示唆する可能性がある。
研究 の 目的:
- 多肢的な非侵襲的電気診断技術の有用性を評価すること。
- COVID-19後SFNが疑われる症候性個人を評価すること。
主な方法:
- 交感神経皮膚応答、皮膚サイレント期間、定量的温熱閾値、および電気化学的皮膚伝導を含む非侵襲的SFNプロトコルを利用した。
- ルーチンの神経生理学的検査および包括的な臨床的、心理測定的、機能的評価を実施した。
- 小線維ニューロパチー スクリーニングリスト(SFNSL)質問票、6分間歩行試験、NASAリーンテスト、COMPASS-31、ED-5D-5L、MFIS、およびPHQ-9を含めた。
主要な成果:
- 9人中3人(33%)がSFNの神経生理学的証拠を示した。参加者の年齢中央値は47.8歳で、COVID-19感染から中央値で23.0ヶ月後であった。全参加者が著しい障害と生活の質の低下を報告した。
結論:
- Post-COVID-19は、機能的障害および生活の質の低下と関連している。
- 神経障害および自律神経症状を示唆する患者においては、SFNを考慮すべきである。

Many organic, inorganic, and biological molecules contain spin-half nuclei such as nitrogen-15, fluorine-19, and phosphorus-31. As a result, NMR studies of these nuclei have found extensive applications in chemical and biological research.
While fluorine-19 and phosphorous-31 have high natural abundances (100%) and positive gyromagnetic ratios, nitrogen-15 has a low natural abundance and a negative gyromagnetic ratio. However, nitrogen-15 is still preferred over nitrogen-14 (which has a...

Testes: Histology
3.0K
A tough, fibrous membrane, the tunica albuginea, covers the testes, extending inward to form fibrous partitions or septa, dividing them into internal compartments called lobules. Each lobule has 1 to 3 tightly coiled seminiferous tubules where sperm production occurs. These tubules merge into a tubular network at the back of the testis, known as the rete testis. It connects to 15 to 20 efferent ductules, leading to the epididymis.

Complementation Tests
6.3K
A complementation test is a simple cross to identify whether the two mutations are located on the same gene or different genes. It was first performed by Edward Lewis in the 1940s while working on fruit flies. He developed the test to identify the location and arrangement of different mutations on chromosomes.
Organisms heterozygous for different mutations are crossed pairwise in all combinations. If present on different genes, the mutations can complement each other by providing the missing...

Significance Testing: Overview
12.7K
Significance testing is a set of statistical methods used to test whether a claim about a parameter is valid. In analytical chemistry, significance testing is used primarily to determine whether the difference between two values comes from determinate or random errors. The effect of a particular change in the measurement protocol, analyst, or sample itself can cause a deviation from the expected result. In the case of a suspected deviation/outlier, we need to be able to confirm mathematically...

Testes: Gross Anatomy

The testes, also known as testicles, are the male gonads. They are housed within the scrotum, a sac-like structure located beneath the penis. The scrotum's primary role is to regulate the temperature of the testes, which is crucial for sperm production.
Each testis is surrounded by the tunica albuginea, a dense connective tissue layer that provides structural support and protection. This layer is covered by an outer serous membrane called the tunica vaginalis, which helps reduce friction...

Testing Water Quality
391
When the quality of water for concrete preparation is uncertain, its impact on the setting time of cement and compressive strength of mortar is assessed by comparison with de-ionized or distilled water benchmarks. American Society for Testing and Materials (ASTM) C1602 requires the setting times to be within 90 minutes of the control, British Standard (BS) 3146:1980 allows a 30-minute variance in the initial setting, while British Standards European Norm (BS EN) 1008 specifies initial setting...
