Chemosensory genes play a central role in sensing chemical signals and guiding insect behavior. The Chinese honeybee, Apis cerana cerana, is one of the most important insect species in China in terms of resource production, and providing high-quality products for human consumption, and also serves as an important pollinator. Communication and foraging behavior of worker bees is likely linked to a complex chemosensory system. Here, we used transcriptome sequencing on adult A. c. cerana workers of different ages to identify the major chemosensory gene families and the differentially expressed genes(DEGs), and to investigate their expression profiles...

In the highly fragmented landscape of central Europe, dispersal is of particular importance as it determines the long-term survival of animal populations. Dispersal not only secures the re-colonization of patches where populations went extinct, it may also rescue small populations and thus prevent local extinction events. As dispersal involves different individual fitness costs, the decision to disperse should not be random but context-dependent and often will be biased towards a certain group of individuals (e...

Planar cell polarity (PCP)-signaling and associated tissue polarization are evolutionarily conserved. A well documented feature of PCP-signaling in vertebrates is its link to centriole/cilia positioning, although the relationship of PCP and ciliogenesis is still debated. A recent report in Drosophila established that Frizzled (Fz)-PCP core signaling has an instructive input to polarized centriole positioning in non-ciliated Drosophila wing epithelia as a PCP read-out. Here, we review the impact of this observation in the context of recent descriptions of the relationship(s) of core Fz-PCP signaling and cilia/centriole positioning in epithelial and non-epithelial cells...

An efficient ferrocenyl BODIPY based dark quencher has been developed and employed to construct a FRET-based fluorescent probe that contains a biotin moiety as a potential directing ligand for cancer cells and a glutathione-cleavable disulfide linker connecting the quencher and a distyryl BODIPY fluorophore. This molecular probe is deactivated in the native form through FRET followed by intramolecular charge transfer due to the ferrocenyl unit. However, upon interaction with glutathione in phosphate buffered saline and inside cancer cells, the fluorescence emission is significantly increased due to detachment of the fluorophore from the quencher...

Dural arteriovenous fistulas (DAVFs) presenting with ocular symptoms, such as exophthalmos and chemosis, are commonly situated in cavernous sinus (CS). DAVFs at the sphenoid wing with a drainage route into the superior orbital vein (SOV) should be considered as one of differential diagnosis of ocular symptoms. A 41-year-old woman presented with progressive left-sided chemosis and proptosis after left pulsating tinnitus that disappeared spontaneously. Cerebral angiography showed that the fistula was situated along the inferior edge of the superior orbital fissure on the greater sphenoid wing and drained solely into the SOV without flowing into the CS that caused ocular symptoms...

Fraud in milk and dairy products occurs when cow milk is added to sheep and goat milk for economic reasons. No reliable, selective, and sensitive method exists for quantifying the milk percentage of different species. This work reports the development and validation of a proteomics-based method for the qualitative detection and quantitative determination of cow, sheep, and goat milks in the raw materials used for dairy products. β-Lactoglobulin was selected as the protein marker because it is a major protein in milk and whey powder...

PURPOSE: The classic symptoms and signs of carotid cavernous sinus fistula or cavernous sinus dural arteriovenous fistula (AVF) consist of eye redness, exophthalmos, and gaze abnormality. The angiography findings typically consist of arteriovenous shunt at cavernous sinüs with ophthalmic venous drainage with or without cortical venous reflux. In rare circumstances, the shunts are localized outside the cavernous sinus, but mimic symptoms and radiography of the cavernous shunt. We would like to present the other locations of the arteriovenous shunt, which mimic the clinical presentation of carotid cavernous fistulae, and analyze venous drainages...

Forensic entomology is primarily concerned with the estimation of time since death and involves determination of the age of immature insects colonising decomposing remains. Accurate age determination of puparia is usually accomplished by dissection, which means destructive sampling of evidence. As part of improving abilities to correctly identify species and developmental age, it is highly desirable to have available non-destructive methods. In this study, we acquired external hyperspectral imaging (HSI) data (77 spectral bands, 389-892 nm) from the dorsal and ventral sides of individual puparia of two species of blowfly (Diptera: Calliphoridae), Calliphora dubia Macquart 1855 and Chrysomya rufifacies Macquart 1842...
