HCN4 is the main isoform expressed in the sinoatrial node, but low levels of HCN1 and HCN2 have also been reported.The current through HCN channels, called the pacemaker current (I f), plays a key role in the generation and modulation of cardiac rhythmicity, [13] as they are responsible for the spontaneous depolarization in pacemaker action potentials in the heart.
The Việt Minh (Vietnamese: [vîət mīŋ̟] ⓘ, chữ Hán: 越盟) is the common and abbreviated name of the League for Independence of Vietnam (Vietnamese: Việt Nam Độc lập Đồng minh [1] or Việt Nam Độc lập Đồng minh Hội, chữ Hán: 越南獨立同盟(會); French: Ligue pour l'indépendance du Viêt Nam), which was a communist-led national independence coalition ...

The Ho Chi Minh Trail (Vietnamese: Đường mòn Hồ Chí Minh), also called Annamite Range Trail (Vietnamese: Đường Trường Sơn) was a logistical network of roads and trails that ran from North Vietnam to South Vietnam through the kingdoms of Laos and Cambodia.
NaCN + H + → HCN + Na + Because the salt is derived from a weak acid, sodium cyanide readily reverts to HCN by hydrolysis; the moist solid emits small amounts of hydrogen cyanide, which is thought to smell like bitter almonds (not everyone can smell it—the ability thereof is due to a genetic trait [7]). Sodium cyanide reacts rapidly with ...
HCN may refer to: Science and mathematics. HCN channel, a cellular ion channel; Highly composite number, a type of integer; Hydrogen cyanide, chemical with the ...
The only evidence that he was in the United States is a single letter to French colonial administrators dated 15 December 1912 and postmarked New York City (he gave his address as the poste restante in Le Havre and his occupation as a sailor) [22] and a postcard to Phan Chu Trinh in Paris where he mentioned working at the Omni Parker House ...
Since the initial detection, HCNH + has also been observed in TMC-1 [15] [16] as well as DR 21(OH) [15]. [17] The initial detection toward Sgr B2 has also been confirmed. [15] [18] All 3 of these sources are dense molecular clouds, and to date HCNH + has not been detected in diffuse interstellar material.
