Comparison of traditional Chinese acupuncture, minimal acupuncture at non-acupoints and conventional treatment for chronic sinusitis.

Objectives: To compare traditional Chinese acupuncture, minimal acupuncture at non-acupoints and conventional treatment for chronic sinusitis.

Design: A three-armed single blind randomised controlled study.

Setting: In an outpatient specialist clinic, we recruited 65 patients with symptoms of sinusitis >3 months and signs of sinusitis on computed tomography (CT).

Environmental interactions of Sulphlex pavement.

Sulphlex, a mixture of elemental sulfur and plasticizers, has been considered for use as an asphalt substitute in road construction. Because this material contains substantial quantities of elemental sulfur, it is a potential substrate for growth of sulfur-oxidising bacteria. Experiments, performed to determine the susceptibility of Sulphlex in Sulphlex-containing media to degradation by Thiobacillus thiooxidans, resulted in breakdown of the Sulphlex material and concomitant production of acid.

Wheel running of kangaroo rats, Dipodomys merriami, as related to food deprivation and body composition.

Kangaroo rats deprived of food ran themselves to death in 48 h in wheel cages. Despite the loss of 14.5% of body weight the ratio of water to protein was the same after the run as it was in control rats.

Capacity of young males and females for running in desert heat.

Tolerance for sustained activity in the desert at about 40 degrees C was assessed on high school students, mostly athletically oriented and scholastically superior. The 14 males compared with the 12 females had an aerobic capacity greater by about one-half and a percentage of body fat smaller by about one-half. Each sex attained about the same percentage of aerobic capacity in their maximal sustained effort.

Physiological adjustments of young men to five-hour desert walks.

Seven young men undertook a desert walk of 30 km at a rate of 100 m/min. Six finished; the seventh stopped after 24 km. Each satisfied his thirst with cool tap water each hour.
