could find no other major social or environmental change that occurred in the population we served which mighthave explained these striking findings. We agree with Dr Platt that it would have been advantageous to compare our experience with that of similar districts in England. Despite strenuous efforts, however, we could not obtain comparable data of this type. The experience in the Edinburgh ...

This paper describes a partial reimplementation of Doug Smith's CYPRESS algorithm design system within the Soar problem-solving architecture. The system, CYPRESS-SOAR, reproduces most of CYPRESS' behavior in the synthesis of three divide-and-conquer sorting algorithms from formal specifications. CYPRESS-Soar is based on heuristic search of problem spaces, and uses search to compensate for missi...

Objective: To determine the efficacy of the antihistamine bepotastine on treating nasal symptoms in patients with Japanese cedar and cypress pollinosis, based on two previous studies that looked at bepotastine OD's inhibitory effect on symptom onset after exposure. Design and methods: Randomized double-blind placebo controlled, parallel study. Twenty-eight volunteers with Japanese cedar and cyp...

In the swampy floodplains of North Carolina’s Black River stand ancient trees with a story to tell. Many of these bald cypress (Taxodium distichum) were well over a millennium old when Columbus discovered the Western Hemisphere. As it turns out, their locale has greatly promoted their longevity: by being relatively inaccessible, the trees have been spared from loggers’ saws. But the inexorable ...

Forest management often results in changes in soil microbial communities. To understand how forest management can change microbial communities, we studied soil microbial abundance and community structure in a natural Chamaecyparis (NCP) forest, a disturbed Chamaecyparis (DCP) forest, a secondary (regenerated) Chamaecyparis (SCP) forest and a secondary (reforested) Cryptomeria (SCD) forest. We a...

BACKGROUND Cupressaceae pollen allergy is a worldwide winter pollinosis. Exposure to cypress pollen has increased enormously during recent decades, and cypress pollen allergy has become a major health problem, especially in Mediterranean countries. OBJECTIVES We aimed to evaluate the prevalence of cypress pollen sensitization and allergy in the Montpellier area and the symptoms presented by s...
