Somnoforme: A Century After The Introduction Of The "Ideal" Anesthetic Gas, James W. Heitz, Md
Somnoforme: A Century After The Introduction Of The "Ideal" Anesthetic Gas, James W. Heitz, Md
Department of Anesthesiology Faculty Papers
Since the introduction of ether as a general anesthetic, there has been a continuous quest to develop the ideal anesthetic gas. The attributes of the ideal anesthetic gas have evolved over time. At the beginning of the 20th century, the search for the ideal anesthetic was focused upon finding an anesthetic gas with rapid inhalation induction and rapid emergence that could be delivered without cumbersome apparatus and would have limited potential for toxicity. Somnoforme was a mixture of ethyl chloride, methyl chloride, and ethyl bromide designed to provide powerful efficacy with low potential for side effects by blending of several …

BACKGROUND: The perception of sour taste in humans is incompletely understood at the receptor cell level. We report here on two patients with an acquired sour ageusia. Each patient was unresponsive to sour stimuli, but both showed normal responses to bitter, sweet, and salty stimuli.
METHODS AND FINDINGS: Lingual fungiform papillae, containing taste cells, were obtained by biopsy from the two patients, and from three sour-normal individuals, and analyzed by RT-PCR. The following transcripts were undetectable in the patients, even after 50 cycles of amplification, but readily detectable in the sour-normal subjects: acid sensing ion channels (ASICs) 1a, 1beta, 2a, …

PURPOSE: This longitudinal study was designed to examine changes in medical students' empathy during medical school and to determine when the most significant changes occur.
METHOD: Four hundred fifty-six students who entered Jefferson Medical College in 2002 (n = 227) and 2004 (n = 229) completed the Jefferson Scale of Physician Empathy at five different times: at entry into medical school on orientation day and subsequently at the end of each academic year. Statistical analyses were performed for the entire cohort, as well as for the "matched" cohort (participants who identified themselves at all five test administrations) and the "unmatched" …

BACKGROUND AND OBJECTIVE: Anaesthetic preconditioning (APC) exerts cardioprotective effects by reducing infarct size and improving recovery of contractile function after ischaemia-reperfusion. The interval between brief exposure to volatile anaesthetic and sustained ischaemia, the acute memory phase, is dependent on intracellular signalling mediating this cardioprotection. Intramyocyte translocation of protein kinase C (PKC) is known to be a key mediator in APC. We examined the relationship between the time frame of the acute memory phase of sevoflurane preconditioning and intramyocyte translocation of PKC-alpha, delta and epsilon to the particulate fraction. METHODS: Isolated perfused guinea pig hearts were subjected to 30 min ischaemia …
