A DNA clone containing a putative enolase gene was isolated from a genomic DNA library of the anaerobic fungus Neocallimastix frontalis. It was deduced from sequence comparisons that the enolase gene was interrupted by a large 331 bp intron. The enolase gene, termed enol, has an ORF of 1308 bp and encodes a predicted 436 amino acid protein. The deduced amino acid sequence shows high identity (7...

Dendroctonus frontalisZimmermann is considered one of themost important economic and ecological forest pests in the United States, Mexico, and Central America. Recently, two apparent morphological variants of this species were discovered occurring syntopically in Central America and southern Mexico. Morphotype A beetles lack a series of Þne parallel ridges on the episternal area of the prothora...

The changes provide an interesting example of Hyperostosis frontalis interna referred to by pathologists as the Morgagni-Stewart-Morel syndrome.

one of his opinions drawn from them is supported by the following case which was admitted during the last month at the General Hospital. Mr. Hutchinson states in the report referred to that " it is only when the side of the no^e is affected that any serious inflammation of the eye ensues." The scars produced by the disease remain for life, and show well how it must have been arranged and tile c...

1. Bark beetles and their predators are useful systems for addressing questions concerning diet breadth and prey preference in arthropod natural enemies. These predators use bark beetle pheromones to locate their prey, and the response to different pheromones is a measure of prey preference. 2. Trapping experiments were conducted to examine geographic variation in the response to prey pheromone...

INTRODUCTION Normative data for jitter parameters using a disposable concentric needle have been described in a few studies. METHODS Jitter, expressed as the mean consecutive difference (MCD), was measured in the frontalis muscle in 20 subjects by voluntary contraction. RESULTS Mean MCD for individual studies (20, gaussian), all potentials (400, non-gaussian), and 18th highest value (20, ga...

The three most common Ixodes spp. ticks found on songbirds in Western Europe are Ixodes frontalis, I. arboricola and I. ricinus. As the latter species is a generalist, it shares several avian hosts with the two strictly ornithophilic species. Infestations of the three species can overlap in time and space, implying that tick-borne pathogens maintained by the ornithophilic ticks and their hosts ...

The use of parallel structures, such as a Stewart platform (SP), for machine tools is a current trend. Some powerful analytical tools are needed to analyse the effect of errors in parallel structures. A model of a SP was analysed to include all the sources of errors [1]. We developed a similar error model to a Stewart platform and a Modified Stewart platform (MSP). Both SP and MSP designs have ...
