まとめ
フーカを吸うことは 安全だと思われがちですが 内皮の機能が急激に低下します この効果は木炭から生じる一酸化炭素によって隠されていて 伝統的な水瓶の使用は無害ではありません
科学分野:
- 心血管研究
- 肺科
- 毒理学について
背景:
- フーカの喫煙は,若者たちにタバコの安全な代替品として売り込まれる.
- 煙草 の 喫煙 は 内皮 の 機能 を 損なう の で ある が,フルーツ の 味 が ある フカ の タバコ の 影響 は 十分 に 理解 さ れ て い ませ ん.
- タバコの煙には タバコの毒素,ニコチン,木炭の燃焼産物,ナノ粒子,一酸化炭素が含まれています.
研究 の 目的:
- 若い成人の内皮機能に対するフルーツ味の水たまりタバコの急性効果を調査する.
- 炭水化物で加熱したナプキンの効果と 電気で加熱したナプキンの効果を比較する
- 一酸化炭素 (CO) が内皮機能に与える影響を特定する.
主な方法:
- 青年の吸水器喫煙者において,血のニコチン,呼気中の一酸化炭素,および腕動脈の流動媒介拡張 (FMD) を喫煙前と喫煙後に測定した.
- この研究では 炭火で加熱したナプキンを 電気で加熱したナプキンを 喫煙者と比較しました
- COの血管拡張作用を隔離するために,COガスの混合物を吸入した.
主要な成果:
- 炭水化物で加熱したナプキンは,電気で加熱したナプキンやタバコと比較して,排出されたCO濃度が大幅に高かった.
- 電気で加熱した水たまりやタバコを吸うと 口内炎が減り 腸内機能障害が起きました
- 炭火で加熱したナプキンを吸うと口腔炎は減らなかったが,COガスを吸い込むと効果が大きくなった.
結論:
- タバコを吸うと 内皮機能が急激に低下します
- 伝統的なホーカーの喫煙で炭火を燃やすことによる高レベルの一酸化炭素 (CO) は,急性内皮機能不全を隠しています.
- 大きな動脈の内皮機能に関して,水たまりを吸うことは無害ではありません.

The Carbon Cycle
43.7K
Carbon is the basis of all organic matter on Earth, and is recycled through the ecosystem in two primary processes: one in which carbon is exchanged among living organisms, and one in which carbon is cycled over long periods of time through fossilized organic remains, weathering of rocks, and volcanic activity. Human activities, including increased agricultural practices and the burning of fossil fuels, has greatly affected the balance of the natural carbon cycle.

Masking and Demasking Agents
3.6K
EDTA titrations may necessitate masking and demasking agents to temporarily protect a particular metal ion in a mixture from the EDTA reaction. These agents facilitate the sequential analysis of the metal ions by forming stable complexes with some—but not all—metal ions during certain steps.
There are many masking agents, such as cyanide, fluoride, triethanolamine, thiourea, and 2,3-bis(sulfanyl)propan-1-ol (formerly 2,3-dimercapto-1-propanol), with the masking agent chosen based on...

Carbon Skeletons
114.8K
Life on Earth is carbon-based, as all macromolecules that make up living organisms contain carbon atoms. All organic compounds have a carbon backbone. Each carbon atom is tetravalent and can bond with four other atoms, making it an extraordinarily flexible component of biological molecules. Because carbon’s valence electrons are stable, it rarely becomes an ion. As the carbon chain increases in length, structural modifications such as ring structures, double bonds, and branching side...

Internal Combustion Engine
2.7K
The internal combustion engine is a heat engine that uses the byproducts of combustion as the working fluid instead of using a heat transfer medium to transfer heat. The combustion is done in a way that produces high-pressure combustion products that can be expanded through a turbine or piston to create work. Internal combustion engines can again be categorized into three kinds: (1) spark ignition gasoline engines, most commonly used in automobiles, (2) compression ignition diesel engines that...

Oxygen Delivering System I: Nasal Cannula and Face Mask
1.6K
The human body requires oxygen to function, and when the natural process of respiration is hindered, external devices, including the following, are needed to help deliver this vital gas.
Nasal Cannula
A nasal cannula is a lightweight tube split at one end into two prongs and placed in the nostrils. It is typically used to deliver low to medium levels of oxygen.
Suggested flow rate: The suggested flow rate for a nasal cannula typically ranges between 1 and 6 L/min.
Oxygen percentage setting:...
