The procerus sign was described by Romanoand Colosimo (1) in two patients with progressive supranuclear palsy (PSP), being defined as the appearance of vertical wrinkles in the glabellar region and the bridge of the nose due to dystonic contractions of the procerus muscle, associated with a combination of reduced blinking, spasticity, lid retraction, and gaze palsy. This occurs because the proc...

Melanism is a common polymorphism in many insect species that also influences immune function. According to the thermal melanin hypothesis, ectothermic individuals from cooler environments have darker cuticles and higher polyphenol oxidase (PO) levels, which represent a better immunocompetence. In this study, the links among environmental temperature, melanism, and PO activity of Saccharosydne ...

To provide a systematic description of component movements of upper facial chorea in Huntington disease, consecutive videos of 25 active patients with confirmed diagnosis were scored on eye opening, eye closing, and procerus/corrugator contractions. Of the 25 patients evaluated, 76% exhibited intermittently widened palpebral fissures associated with frontalis contractions. Brief periods of repe...

Estimation of the genetic contribution of presenilin-1 and-2 mutations in a population-based study of presenile Alzheimer disease. High prevalence of pathogenic mutations in patients with early-onset dementia detected by sequence analyses of four different genes. mutation ...

The ant genus Odontomachus Latreille is reviewed for Sumatra, the sixth largest island in the world and located in western Indonesia. Previously three species were recorded from the island: O. simillimus F. Smith, O. rixosus F. Smith, and O. latidens Mayr. We add two species to the fauna, O. procerus Emery stat. nov and Odontomachus minangkabau sp. nov. The new species belongs to O. rixosus spe...

UNLABELLED Converging lines of evidence suggest a role for facial expressions in the pathophysiology and treatment of mood disorders. To determine the antidepressant effect of onabotulinumtoxinA (OBA) treatment of corrugator and procerus muscles in people with major depressive disorder, we conducted a double blind, randomized, placebo-controlled trial. In an outpatient clinical research center,...

A new genus of Encyrtidae (Hymenoptera: Chalcidoidea), Noyesencyrtus Singh gen. nov. (type species N. brachyoculus Singh sp. nov.), associated with insects inhabiting fruiting bodies of wood-decaying fungi, and two new species, Psyllaephagus kundapurensis Singh sp. nov. and Ooencyrtus hayatii Singh sp. nov., are described from the Western Ghats of Karnataka, India.

Ancyronyx montanussp. n. is described based on adults and larvae, matched using their cox1 DNA sequence data. Larvae of six additional species of Ancyronyx Erichson, 1847 were also described here for the first time, aided by cox1 or cob data: Ancyronyx helgeschneideri Freitag & Jäch, 2007, Ancyronyx minerva Freitag & Jäch, 2007, Ancyronyx patrolus Freitag & Jäch, 2007, Ancyronyx procerus Jäch, ...
