Little is known about baseline concentrations of adrenal hormones and hormonal responses to stress in sea ducks, although significant population declines documented in several species suggest that sea ducks are exposed to increased levels of environmental stress. Such declines have been observed in geographically distinct harlequin duck populations. We performed an adrenocorticotropic hormone (...

Background: Collodion baby is a rare condition (i.e., 1:300000 birth), which is referred to a neonate covered with a tight and shiny membrane desquamating within two weeks. This condition takes place as a result of the epidermal cornification disorder. Given the impairment of the skin barrier function, these neonates are at the risk of several complications, including hypernatremic dehydration,...

Harlequin bug, Murgantia histrionica (Hahn), is a pest of cole crops in the USA. Laboratory toxicity assays revealed that the neonicotinoid insecticides imidacloprid, thiamethoxam, dinotefuran, and clothianidin are toxic to harlequin bug nymphs; LC50 = 0.57, 0.52, 0.39, and 0.39 ppm, respectively. Field experiments were conducted to evaluate the efficacy of these insecticides over time when app...

We report on WSRT observations of HI and OH absorption at a redshift of z = 0.885 towards the radio lens PKS 1830−21. The mm wave transitions of several molecular species have already been observed in absorption towards PKS 1830−21 at this redshift. At mm wavelengths the source structure is dominated by two extremely compact components, the northeast (NE) and southwest (SW) components. At lower...

The harlequin ladybird, Harmonia axyridis, has emerged as a model species for invasion biology, reflecting its remarkable capacity to outcompete native ladybird species when introduced into new habitats. This ability may be associated with its prominent resistance to pathogens and intraguild predation. We recently showed that the constitutive antibacterial activity present in the haemolymph of ...

SUMMARY We propose a parametric model, HiCNorm, to remove systematic biases in the raw Hi-C contact maps, resulting in a simple, fast, yet accurate normalization procedure. Compared with the existing Hi-C normalization method developed by Yaffe and Tanay, HiCNorm has fewer parameters, runs >1000 times faster and achieves higher reproducibility.

Molecular and geological evidence indicates that the emergence of the Isthmus of Panamá influenced the historical biogeography of the Neotropics in a complex, staggered manner dating back at least 9 Myr bp. To assess the influence of Isthmus formation on the biogeography of the harlequin beetle-riding pseudoscorpion, Cordylochernes scorpioides, we analysed mitochondrial COI sequence data from 7...

Harlequin syndrome is a rare autonomic disorder characterized by unilateral facial flushing and sweating with contralateral anhidrosis induced by exercise, heat, and emotion. It is usually idiopathic but could be the first manifestation of several serious underlying medical conditions. Medical or surgical treatments are not required for idiopathic Harlequin syndrome, but social and psychologica...

RATIONALE Harlequin syndrome is an extremely rare benign condition characterized by unilateral facial flushing and sweating. PATIENT CONCERN An 11-year-old boy presented with complaint of a right neck mass of 1-month duration. DIAGNOSIS The preoperative diagnosis was neurogenic tumor of vagus nerve or sympathetic nerve. INTERVENTIONS We performed right neck mass removal under general anes...
