The Berytidae or stilt bugs are a cosmopolitan family of lygaeoid bugs, which are slender, elongate insects, with generally cylindrical bodies and very long, slender antennae and legs. Members of the tribe Hoplinini are characterized by the lack of a distinct metapleural scent channel and the possession of a dorsally directed process on the caudal edge of the male genitalia capsule (absent in X...

The entangled history of Sciacharis Broun, 1983, a genus in which nearly 240 species were placed by Herbert Franz who has apparently never studied its type species, was recently summarized by Jałoszyński (2014a, b). A synonymy of Chatchamaenus Franz with Sciacharis s. str. was demonstrated, and Maorinus Franz, 1980 was placed as a subgenus of Sciacharis (Jałoszyński 2014a). Still, the systemati...

We study the rigidification phenomenon for several thin slender bodies or shells, with a small curvature in the transversal direction to the main length, for which the propagation of singularities through the characteristics is of parabolic type. The asymptotic behavior is obtained starting with the two-dimensional Love–Kirchoff theory of plates. We consider, in a progressive study, a starting ...

In a previous study M. Hameed et al., J. Fluid Mech. 594, 307 2008 the authors investigated the influence of insoluble surfactant on the evolution of a stretched, inviscid bubble surrounded by a viscous fluid via direct numerical simulation of the Navier–Stokes equations, and showed that the presence of surfactant can cause the bubble to contract and form a quasisteady slender thread connecting...

Glucocorticoids have long been known to accelerate maturation of the intestinal tract, but the molecular mechanisms that account for their physiological function in the epithelium remain poorly characterized. Using rat intestinal epithelial cell lines (IEC-6, IEC-17, and IEC-18) as models, we have characterized glucocorticoid receptors in crypt cells and documented striking morphological, ultra...

The genus Meiyingia Holzchuh, 2010 presently consists of only one species, Meiyingia paradoxa Holzchuh, 2010 from Henan and Shaanxi, China. The genus is characterized by following characters: Head concave between antennal tubercles; clypeus narrow; frons flattened. Eyes small, finely faceted, divided with two lobes widely separated. Antennae slender; those of males longer than the body, with sp...

We describe a new technique for removing a large intraocular foreign body by 25-gauge microincision vitrectomy surgery (25G-MIVS). Noncomparative interventional case series were performed at a single centre. Two patients with a long smooth intraocular vitreal foreign body underwent phacoemulsification and aspiration, intraocular lens implantation, 25G-MIVS, and extraction of the foreign body. T...

A new species of the genus Boca Lowry & Stoddart, 1997 is described from a mesophotic coral ecosystem off southwestern Puerto Rico, in the Caribbean Sea. The new species is easily recognized from the others in the genus mainly by the following characters: (1) maxilliped, inner plate with 2 long apical simple setae; palp, articles slender, subequal in length; (2) gnathopod 1, propodus slightly e...

Whale brains have attracted the attention of neuroscientists but there are only sparse studies on whale glial cells. Here we report on immunolabeling of astrocytes by antibodies to glial fibrillary acidic protein (GFAP) or protein S-100 beta (both by the streptavidin/biotin technique), and labeling of microglial cells by Griffonia simplicifolia agglutinin (GSA I-B4, coupled to horseradish perox...

Upper canines in microchiropteran bats show a variety of cross-sectional shapes. A consistent feature of all species studied here is that the tooth is edged and not simply round or oval. Prominent sharp edges are positioned in several directions but particularly antero-medially toward the incisors and posteriorly toward the premolars. These edges appear to direct the cracks made in food items t...
