Abstract
The aim of this study was to determine whether changes in body position alter feline electrocardiographic parameters. Forty-seven cats referred to the Feline Unit of the University of Bristol had electrocardiograms (ECGs) recorded. Only cats presenting in sinus rhythm were included in the study (n = 41). ECGs were recorded either as part of the investigation for potential cardiac disease (n = 38) or as a preanesthetic screen (n = 3). Standard 6-lead ECGs (leads I, II, III, aVR, aVL, and aVF) were recorded in 3 different recumbent positions in the 41 cats. Recordings were 1st made in right lateral (RL) recumbency, followed by sternal (ST) and then left lateral (LL) recumbency. Measurements were taken of the amplitude and duration of P waves and QRS complexes and duration of PQ and QT intervals from lead II was taken in the 3 different positions. Mean electrical axis (MEA) also was calculated. Repeated measures analysis of variance was performed and identified a significant difference in R wave amplitudes (P = .009) and MEA (P = .037) among the 3 different body positions. Two-tailed paired t-tests demonstrated that the R wave amplitude differed significantly both in ST (P = .025) and LL recumbency (P = .009). The mean R wave amplitude was reduced in both ST and LL recumbency when compared with RL recumbency. The MEA only was significantly different in LL recumbency (P = .037). ST and LL recumbencies should not be used for recording ECGs in cats if amplitudes and MEA are to be compared with standard references.

Abstract
Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a disease characterised by infiltration of the myocardium by adipose and fibrous tissue. The disease is an important cause of sudden death in humans, but has rarely been described in animals. This report describes ARVC in two cats with right-sided congestive heart failure. One cat had also experienced previous episodes of syncope. Standard six-lead and 24-hour (Holter) electrocardiogram recording revealed complete atrioventricular block and multiform ventricular ectopics in both cats, with the addition of ventricular tachycardia, ventricular bigeminy and R-on-T phenomenon in one of them. On echocardiography, the right ventricle and atrium were massively dilated and hypokinetic. The survival times of the cats were three days and 16 days following diagnosis. Histopathology in one case revealed fibro-fatty infiltration of the myocardium, predominantly affecting the right ventricular free wall.

Abstract
Research achievements at the Johns Hopkins School of Medicine over the past century are too numerous to document in anything but a catalog. But a group of Hopkins physicians and researchers compiled a representative sample of papers documenting the intellectual history of the institution, reproducing them in a two-volume text. A discussion with one of the editors, A. McGehee Harvey, M.D., offers some insight into the process of selecting papers to be included in this historic publication.

Abstract
A method was developed to demonstrate recA-dependent P22-repressor breakdown in vivo by SDS-polyacrylamide electrophoresis of unfractionated extracts of phage-infected, lysogenic Salmonella typhimurium strains TA1530 rec+ and TA1530 recA1-. The antirepressor of P22 is not cleaved by recA protein. Under conditions of unregulated ant-overproduction (Harvey et al. 1981) antirepressor protects c2-repressor in vivo against proteolytic cleavage by recA protein.

Abstract
Phage P22 defective in gene 24 and harbouring the Oc mutation k5 in OR exhibits a strongly increased c2-repressor synthesis after infection of non-lysogenic S. typhimurium. The repressor synthesis depends strictly on an intact c1 gene. The kinetics of its synthesis, as monitored by polyacrylamide gel electrophoresis, is the same as with P22 c+, namely a turn off 8-10 min after infection. - After infection of P22-lysogenic bacteria with either P22 24- k5 or P22 24- k5 c1, much lower amounts of repressor are synthesized but again with the same kinetics. These results suggest a cro-like function acting at PRE and PRM of P22. The possible reason for the c2 overproduction is discussed.

Abstract
Analysis of phage-specified protein synthesis after phage infection of UV-irradiated cells shows a turn-off of early gene expression, a regulatory event that is independent of the known P22 regulatory functions. This supports the suggestion of a cro lambda-like function in P22. We have identified the products of genes 18 and int as contributing to the complex 40,000 dalton band in our SDS-polyacrylamide gels. Both gene products appear to be subject to regulation by the cro-like function of P22. Proteins of 33,000, 29,000, 27,000, 25,000, and 24,000 MW, specified by as yet unidentified P22 genes of the early leftward operon, are regulated by the same function. Our data suggest that the cro-like function is expressed from the early rightward operon.
