The predominant features of Harlequin syndrome are unilateral facial flushing and sweating. Harlequin syndrome has been reported in different clinical conditions including brain stem infarction, superior mediastinal neurinoma, and internal jugular vein catheterization.1,2 Idiopathic and iatrogenic cases have been reported. The clinical features of Horner syndrome are ptosis, miosis, enophthalmo...

Harlequin ichthyosis is a rare and the most severe form of congenital ichthyosis. Although prenatal diagnosis isdifficult for this disorder, recently, this obstacle has markedly improved with the use of DNA-based prenataldiagnosis. Here in, we presented a neonate with harlequin ichthyosis born by assisted reproductive technology(ART). In this case, the diagnosis of harlequin ichthyosis was not ...

Harlequin toads (Atelopus) are among the most severely impacted amphibians by the emergence of chytridiomycosis, a fungal disease caused by the pathogen Batrachochytrium dendrobatidis (Bd). Many species disappeared while others suffered drastic contractions of their geographic distribution to lower altitudes. A diminished virulence of Bd in warm habitats was proposed to explain the survival of ...

Reproductive strategy affects population dynamics and genetic parameters that can, in turn, affect evolutionary processes during the course of biological invasion. Life-history traits associated with reproductive strategy are therefore potentially good candidates for rapid evolutionary shifts during invasions. In a series of mating trials, we examined mixed groups of four males from invasive an...

Highly birefringent (Hi-Bi) air-clad silica microfibers (MFs) with wavelength and sub-wavelength scale transverse dimensions are studied theoretically and experimentally. Hi-Bi MFs are taper-drawn from the standard SMF-28 single mode fibers that are "pre-processed" by "cutting away" parts of the silica cladding on opposite sides of the fiber with a femtosecond infrared laser. Such Hi-Bi MFs hav...

OBJECTIVE To explore all the common clinical and biological variables that are characteristic of Systemic onset Juvenile Chronic Arthritis (SoJCA) in order to determine which of them are suitable as predictors of a bad articular outcome (persistence of inflammatory symptoms and/or established limitation of the range of motion (ROM). MATERIAL AND METHODS Clinical charts for 124 SoJCA patients ...

The use of biological control agents to control pests is an alternative to pesticides and a tool to manage invasive alien species. However, biocontrol agents can themselves become invasive species under certain conditions. The harlequin ladybird (Harmonia axyridis) is a native Asian biocontrol agent that has become a successful invader. We reviewed articles containing "Harmonia axyridis" to gat...

Harlequin bug, Murgantia histrionica (Hahn) (Hemiptera: Pentatomidae), is a piercing-sucking pest of cole crops, causing cosmetic damage in low populations, while heavy pest pressure can kill plants or entire fields. Field studies were conducted to evaluate a trap crop for control of harlequin bug in collard. Field-cage choice tests found that potential trap crop plant species, mustard (Brassic...

The relationship between Harlequin Duck Histrionicus histrionicus distribution and stonefly (Plecoptera) nymph availability in the Maligne Valley watershed, Jasper National Park, Canada, was investigated from 1999 to 2000. Invertebrate sampling and duck counts were concentrated in the Maligne Lake Outlet (MLO), Middle Maligne River and Lower Maligne River. Harlequin Ducks were more likely to us...
