To explore the efficacy of modified shortening levator palpebrae superioris muscle on patients with ptosis. A total 78 mild or moderate ptosis admitted to our hospital were enrolled and assigned a control group an observation group. Patients in treated frontalis suspension those two groups was compared. The effective correction rate significantly higher than that ( 92.59 % vs. 78.72 %) at 1st 7...

Introduction: Diverse anatomical characteristics and varied kinetic spectra determine the specific contraction patterns of individuals' frontal facial musculature. Objective: To identify and classify the frontal facial musculature contraction patterns in patients who sought care for treating frontal facial wrinkles. Methods: Retrospective analysis of pictures taken from 83 patients.The muscular...

OBJECTIVE To estimate jitter parameters in myasthenia gravis in stimulated frontalis and extensor digitorum muscles using the concentric needle electrode. METHODS Forty-two confirmed myasthenia gravis patients, being 22 males (aged 45.6±17.2 years-old) were studied. Jitter was expressed as the mean consecutive difference (MCD). RESULTS MCD in extensor digitorum was 61.6 µs (abnormal in 85.7...

OBJECTIVE The transpalpebral resection of the corrugator and depressor supercilii muscles is a new treatment option for migraine headaches. Hyperactive contractility of these muscles can provoke the peripheral compression of the supratrochlear nerve and induce a neurogenic inflammation triggering the symptoms of migraine. In order to gather detailed knowledge of the respective anatomy in the ey...

The southern pine beetle Dendroctonus frontalis Zimmermann (Coleoptera: Curculionidae: Scolytinae) is attracted to an aggregation pheromone that includes the multifunctional pheromone component endo-brevicomin. The effect of endo-brevicomin on attractive lures varies from strong enhancement to reduction of beetle attraction depending upon release rate, lure component spacing, and proximity of b...

We evaluated whether Dendroctonus frontalis Zimmermann populations were inßuenced by nontrophic interactions involving commensal mites, their mutualistic bluestain fungus Ophiostoma minus (Hedgc.) H. and P. Sydow, and beetle-mutualistic mycangial fungi. We tested for effects of delayed, nonlinear, or positive feedback fromO. minus and mites onD. frontalis population growth. We predicted that (1...

Dendroctonus frontalis Zimmermann (Coleoptera: Curculionidae: Scolytinae) is a major economic pest of pines in the United States, Mexico, and Central America.We report biochemical investigations relevant to the taxonomic status and semiochemistry of two distinct morphotypes ofD. frontalis recently detected in theCentralAmerican region.MorphotypeAbeetles (pre-episternal area of prothorax of both...

Subtle differences in pheromone components of sympatric species should be attractive only to the producing species and unattractive or repellent to the nonproducing species, and thereby maintain reproductive isolation and reduce competition between species. Bark beetles Dendroctonus brevicomis and D. frontalis (Coleoptera: Curculionidae) are known to have common pheromone components, except for...

PURPOSE The purpose of this study is to report a case of nontuberculous mycobacterial infection after frontalis sling surgery. METHOD A 65-year-old man presented with bilateral painful, erythematous lesions in the brow and upper eyelids. He had a history of frontalis sling surgery for myopathic ptosis 2 years back and all lesions were found localized to the tract of the silicone rod used in t...
