The analysis of humour

INTRODUCTION Theories of humour are traditionally divided into two classes: superiority or relief theories, and incongruity or ambiguity theories. As their names imply, the former tend to ascribe amusement primarily to a particular attitude of mind, while the latter account for it by describing its objects as having a particular quality. Enjoyment as an attitude is always a response to an object present to the mind or feelings. If, then, enjoyment in amusement is identical with feelings of superiority or relief, its objects must always display characteristics of inferiority or inhibition. But the enjoyment of humour seems to be distinguishable from a reaction to particular kinds of topic, and from any personal relation felt between the subject and the objects of his amusement. Incongruity theories do not explicitly ascribe the enjoyment of humour to a particular range of topics.

Mechanisms of endothelin-1 induced reactive oxygen species production in vascular adventitial fibroblasts

With the relationship between endothelin-1 (ET-1) stimulation and reactive oxygen species (ROS) production unknown in adventitial fibroblasts, I examined the ROS response to ET-1 and angiotensin (Ang II). ET-1 -induced ROS peaked following 4 hrs of ET-1 stimulation and was inhibited by an ETA receptor antagonist (BQ 123, 1 uM) an extracellular signal-regulated kinase (ERK) 1/2 inhibitor (PD98059, 10 uM), and by both a specific, apocynin (10 uM), and non-specific, diphenyleneiodonium (10 uM), NAD(P)H oxidase inhibitor. NOX2 knockout fibroblasts did not produce an ET-1 induced change in ROS levels. Ang II treatment increased ROS levels in a biphasic manner, with the second peak occurring 6 hrs following stimulation. The secondary phase of Ang II induced ROS was inhibited by an ATi receptor antagonist, Losartan (100 uM) and BQ 123. In conclusion, ET-1 induces ROS production primarily through an ETA-ERKl/2 NOX2 pathway, additionally, Ang II-induced ROS production also involves an ETa pathway.

John Adams Smith letter, Jan. 14, 1813

Transcript: New York Jan. 14. 1813. My dear uncle, I had nearly concluded to have made my [jaunt?] earlier than I had mentioned in my last letter to you, for Swartout had intended to have written by me to Father & yourself; having [Louisa?] concluded not so soon to depart he sends me his letters which I forward in mail, I shall hope to have letters from home soon, it is a great pleasure to hear from any of you. I said last week in Hollands letter mentioning [bladeworth?] account, I have explained to him. It is a mistake about me agreeing to pay Mr. [Dening?] [their?] account. Caroline mentions to me your jaunt to [Sophia?], but I regret our friend there should be unpleasantly situated. I have not yet seen Col. Willett but will see him as mentioned. I have neglected to go there for some time which has been remiss in me. We have nothing new I believe unless it be that Armstrong & Jones of Philadelphia have been nominated as Secretarys of War & the Navy & [cer?] this in all probability may be appointed. There may be room for speculation, but perhaps it is not probable that Canada will be ceded to American Valor in the year 1813. There is a Bill before congress by which it may be made penal to enter on board American vessels, either British subjects or naturalized Americans, which it is presoomed by many will [spon?] the accommodation of Peace – may be yes may be no – the proof of the pudding is in the eating of it. I imagine pacification is not so near at hand although it is much to be desired. Whatever might be for the honor & prosperity of the Country I would strenuously advocate, aloof from partial & party considerations. We have not a word as yet what the Council at Albany may be thinking of as yet. I suppose these things will come in time, perhaps untimely to many. I desire for the present not to be found among the untimely. I am your sincerely, with love to all. John Adams Smith
