まとめ
インドシアニングリーン(ICG)リンパ造影法による上肢のリンパドレナージのマッピングは、前腕の主要な経路を明らかにする。前腕背側の経路は上腕の経路にのみ排出され、乳がん関連リンパ浮腫(BCRL)のリスクにおいてその重要性が強調される。
科学分野:
- 解剖学; 生理学; 医用画像処理
背景:
- 従来のリンパ解剖学は死体解剖に依存している。; インドシアニングリーン(ICG)リンパ造影法は、表在リンパ系に関する機能的な洞察を提供する。; ICGリンパ造影法は、上肢における主要な解剖学的変異を詳細に説明する。
研究 の 目的:
- 上肢表在リンパ系の機能的解剖をマッピングする。; ICGリンパ造影法を用いて主要な解剖学的変異と経路の接続性を特定する。; 乳がん関連リンパ浮腫(BCRL)のリスクとリンパドレナージパターンを相関させる。
主な方法:
- 健常な女性ボランティアを対象に上肢のICGリンパ造影法を実施した。; 手/手首および上腕の標準的な部位にICGを注入した。; 4つの主要な前腕経路とその4つの上腕経路への接続性を分析した。
主要な成果:
- 90本の腕(45人のボランティア)を分析した。; 後撓骨および尺骨前腕経路は主に背側に走行する。; 前撓骨および尺骨前腕経路は掌側にのみ走行する。; 特定の前腕経路は、上腕リンパ管との明確な接続を示した。
結論:
- 前腕背側のリンパ管は、外側および三頭筋上腕経路にのみ排出される。; これらの前腕背側の経路は、BCRLリスクの理解に不可欠である。; 上肢リンパ系の解剖学的変異は、BCRLの予防と治療にとって重要である。

What is Variation?
17.6K
Apart from the measures of central tendency, distribution, outliers, and the changing characteristics of data with time, an important characteristic of any data set is its variation or spread. In some data sets, the data values are concentrated closely near the mean; in others, the data values are more widely spread out from the mean.
The range, standard deviation, standard error, and variance are the different measures of variation.
Range: The range is the difference between its maximum and...

Development of the Lymphatic System
2.0K
The development of lymphatic tissues and vessels in embryonic life begins around the fifth week. These structures originate from the mesoderm layer, with lymph sacs emerging from developing veins.
The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...

Variation
7.7K
An important characteristic of any set of data is the variation in the data. In some data sets, the data values are concentrated closely near the mean; in other data sets, the data values are more widely spread out from the mean. The most common measure of variation, or spread, is the standard deviation, which is the square root of variance.
When independent and dependent variables are plotted on a scatter plot, the slope of a line is a value that describes the rate of change between the two...

Conservative Site-specific Recombination and Phase Variation
6.7K
Because the DNA segments are cut and reorganized in a direction-specific manner, site-specific recombination has emerged as an efficient genetic engineering technique. Flippase and Cyclization recombinases or Flp and Cre, respectively, are two members of the tyrosine recombinase family derived from bacteriophages, that are used to mediate site-specific DNA insertions, deletions, and targeted expression of proteins in mammalian cell lines.

Major Organs of the Digestive System

The digestive system is responsible for the ingestion of food, secretion of enzymes, mixing and digesting food, absorption of the nutrients and defecation. The human digestive system consists of two major parts: the gastrointestinal tract and the accessory digestive organs.

Variation of Atmospheric Pressure
4.1K
Change in atmospheric pressure with height is particularly interesting. The decrease in atmospheric pressure with increasing altitude is due to the decreasing gravitational force per unit area as we move away from the surface of the earth.
Assuming the air temperature is constant at a given altitude and that the ideal gas law of thermodynamics describes the atmosphere to a good approximation, one can find the variation of atmospheric pressure with height.
Let p(y) be the atmospheric pressure at...
