Dendroctonus frontalis Zimmermann (Coleoptera: Scolytinae) is the most serious pest of pines (Pinus spp.) in Mexico. Conspecifics are attracted to trees undergoing colonization by the aggregation pheromone frontalin, which is synergized by odors of pine oleoresin released from beetle-damaged host tissue. Synthetic racemic frontalin combined with turpentine has been the operational bait used in ...

BACKGROUND The forehead is a common site for injection of botulinum neurotoxin type A (BoNT-A) to treat hyperactive facial muscles. Unexpected side effects of BoNT-A injection may occur because the anatomy of the forehead musculature is not fully characterized. OBJECTIVES The authors described the lateral border of the frontalis in terms of facial landmarks and reference lines to determine th...

Hyperostosis frontalis interna is a curious abnormality of the inner tables of the frontal bones of the skull, said to have been first described by Morgagni in 1761. It consists of aggregations of smooth, rounded enostoses which are covered by dura mater and project into the cranial cavity. Most are about 0 5 to 1 0 cm. in diameter at their bases and attain a similar height. The enostoses do no...

Seventeen patients with ptosis as a feature of chronic progressive external ophthalmoplegia were managed in accordance with a new protocol. An anterior approach levator advancement was performed on seven patients (13 lids) with more than 4 mm of levator function and a brow suspension procedure on eight patients (14 lids) with minimal levator function, in whom the frontalis muscle was relatively...

Scherer's Component Process Model provides a theoretical framework for research on the production mechanism of emotion and facial emotional expression. The model predicts that appraisal results drive facial expressions, which unfold sequentially and cumulatively over time. In two experiments, we examined facial muscle activity changes (via facial electromyography recordings over the corrugator,...

BACKGROUND Ptosis is an abnormally low position of the upper eyelid. Congenital ptosis should be corrected in early years of childhood. The aim of this study was to assess the efficacy and complications of frontalis suspension using silicon tube for simple congenital blepharoptosis with poor levator function.
