The Satellite Meeting on Na+/H+ Exchangers, held on 17 April 2010, covered a range of new developments in this field. The symposium was chaired by Dr. Larry Fliegel, University of Alberta, and the speakers were Dr. John Orlowski of McGill University, Dr. Jan Rainey of Dalhousie University, Dr. Etana Padan ...

Given the well-known difficulties in defining and detecting fatigue, it is a real challenge to incorporate it into either traffic or criminal law. Finnish traffic law forbids fatigued driving "only" on a general level concerning the driver's fitness to drive. We present several comments from Finnish traffic and local police ...

A case is presented of a 28-year-old woman with right upper lobe atelectasis secondary to sarcoid adenopathy. As most chest surgeons and physicians would currently remove the offending lymph nodes for lung reexpansion and more definitive diagnosis, the case is considered primarily for its historical interest.

During 1972 and 1973 the Salmonella and Shigella Reference Laboratory examined 133 strains of Shigella dysenteriae and Shigella boydii isolated from patients in England and Wales. Of those infected 89 had recently travelled abroad and a further seven had been in close contact with travellers recently returned to this country. ...

Four children are described who had hypoplastic optic nerves, absent septa pellucida, and various types of endocrinological dysfunction. The importance is stressed of recognizing this syndrome and of following up the growth of the patient, because now that human growth hormone is available the short stature of some blind children ...

New insecticides have been evaluated for toxicity to tsetse flies and compared with organochlorine compounds currently in use. The most toxic compounds and their estimated median lethal doses in nanograms per fly by topical application in solution to teneral Glossina austeni were: resmethrin 4, fenthion 8, dieldrin 10, propoxur 12, ...

A project of the Tides Center, CETOS is a non-profit making environmental group that is concerned with the toxicity from chemical exposures; deleterious impacts on agriculture and the environment through intensive use of pesticide; loss of endangered species caused by contamination of habitats, and the protection of genetic integrity of ...

Two children developed erythema nodosum due to Pasteurella pseudotuberculosis. Neither case showed typical signs of P. pseudotuberculosis infection, but this cause was shown by positive agglutination tests. It is suggested that this organism is a more common cause of erythema nodosum than is at present recognized.

From 1960 to 1965, 44,629 cultures were performed on persons attending chest clinics in the Niagara Peninsula.Tubercle bacilli were cultured from 965 biological specimens (2.16%) and atypical mycobacteria from 281 specimens (0.62%).Twelve subjects had more than one variety of atypical mycobacterium in their secretions, suggesting the occurrence of mutation. The ...

Light isomerizes the chromophore of rhodopsin, 11-cis retinal (formerly retinene), to the all-trans configuration. This introduces a succession of unstable intermediates-pre-lumirhodopsin, lumirhodopsin, metarhodopsin -in which all-trans retinal is still attached to the chromophoric site on opsin. Finally, retinal is hydrolyzed from opsin. The present experiments show that metarhodopsin exists in ...

Although many factors combine to make Latin America an apparently suitable region for the spread of the leptospiroses, the prevalence of these infections has been studied in relatively few areas of this part of the American continent. Of the 60 Leptospira serotypes described in the world, only seven have so ...

The toxicity of DDT, dieldrin, endrin, malathion, parathion, Systox and P4 to larvae and pupae of Culex fatigans has been studied. Two colonies of mosquitos were maintained for the purpose-one at 88 degrees +/-2 degrees F (31.1 degrees +/-1.1 degrees C) and 70%-80% relative humidity, and the other at 72 ...
