Meteorological effects on the biting activity of Leptoconops americanus(Diptera: Ceratopogonidae).

Collections of biting Leptoconops americanus were made at half-hour intervals throughout the daylight hours on Stansbury Island, UT, during 9 days in May, 1993. The most favorable conditions for biting (> or = 90 bites on the ears in 15 min) included temperatures higher than 15 degrees C, minimum wind (< 5 kph), minimum cloud cover, maximum sun, and no rain. Temperatures below 10 degrees C or the presence of rain prevented almost all biting. Higher winds and cloudiness decreased biting activity, but did not eliminate it if other conditions were favorable. Although not statistically significant, there was some suggestion from the data that higher temperatures (> 25 degrees C) reduced biting. The flies did not appear to be more numerous at any particular part of the day; the biting rate simply followed meteorological conditions at the time. Ambient light varied between 1 and 10,000 foot candles during the study, with high biting rates (76 and 99 bites per 15 min) observed at levels as low as 80-100 foot candles.

Comparative analysis of macromolecules in mollusc shells.

1. Proteins and polysaccharides were isolated from the shells of molluscs; blue mussel, Mytilus edulis, chambered nautilus, Nautilus pompilius, and red abalone, Haliotus rufescens. 2. N-acetyl glucosamine was detected in nautilus but not mussel or abalone. 3. Amino acid analysis of protein fractions was completed for the three molluscs and purified proteins from the mussel were partially sequenced. 4. Calcium binding studies were carried out with some of the protein fractions.

Classics in oncology. Survey of current opinions concerning carcinoma of the breast occurring during pregnancy. J. Harold Cheek, M.D. Am. Arch. Surg. 1953.

A questionnaire dealing with problems relating to carcinoma of the breast occurring in pregnancy has been submitted to a number of physicians considered to be well informed on this subject. The replies have been tabulated and analyzed. Some features of the disease as seen in pregnancy are discussed, and some of the factors responsible for its poor prognosis are considered. The response to the survey indicates that the results of the treatment of carcinoma of the breast occurring in pregnancy are very disappointing.
