Check list of first recorded dragonfly (Odonata: Anisoptera) fauna of District Lower Dir, Khyber Pakhtunkhwa, Pakistan [PDF]

open access: yesArthropods, 2014
The dragonflies (Odonata: Anisoptera) are large, intermediate to small size, having different colours and variable morphological characters. They also carry ornamental and environmental indicator values.

Flight of the dragons: a global review of migration in Odonata

open access: yesBiological Reviews, EarlyView.
ABSTRACT Insects are the most abundant and ecologically important animal migrants. Yet, we know relatively little about the patterns and processes underlying insect migration. Dragonflies (Anisoptera) and damselflies (Zygoptera) comprise the ancient insect order Odonata, whose ancestors were the first organisms to fly on Earth.

Do egg parasitoids increase the tendency of Lestes sponsa (Odonata: Lestidae) to oviposit underwater?

open access: yesEuropean Journal of Entomology, 2015
The selection of oviposition sites by insects can significantly affect egg mortality. Spreadwing damselflies (Odonata: Lestidae) predominantly lay their eggs in parts of plants growing above the surface of water and only occasionally also those parts ...

Calcified Plaque Detachment: Alternative Calcified Plaque Modification After Coronary Intravascular Lithotripsy

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Calcified plaque (CP) detachment (CD) and calcium fracture (CF) can occur following coronary intravascular lithotripsy (IVL). The extent to which CF alone facilitates stent expansion during CP modification with IVL remains unclear. Aims This study aimed to investigate the clinical implications of IVL‐induced CD.

Motorway as a barrier to dispersal of the threatened dragonfly Sympetrum depressiusculum (Odonata: Libellulidae): Consequence of mortality or crossing avoidance?

open access: yesEuropean Journal of Entomology, 2017
Infrastructure is one of the main causes of landscape fragmentation, which results in isolation and loss of populations. Although the negative effect of roads on insects is well documented, only a minority of studies has focused on roads in the context ...

Investigating the Cytoskeleton of DRGs Using Cryo‐Electron Microscopy and Deep Learning

open access: yesCytoskeleton, EarlyView.
ABSTRACT We describe a method for determining the ultrastructural organization of axons and varicosities of cultured dorsal root ganglion (DRG) neurons using cryogenic electron microscopy (cryo‐EM). Cryo‐EM reveals the dimensions, proximity, and overall organization of biological specimens in a near‐native state, avoiding artifacts of fixation and ...

Jaw‐specific stem cell dynamics are associated with distinct enamel architecture in mouse incisors

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background The continuously growing mouse incisor serves as a model for stem cell‐driven tooth renewal. Although mice possess maxillary and mandibular incisors, most studies have focused on the mandible. Potential differences in structure and renewal between these serially homologous organs remain insufficiently characterized.

Bio‐inspired vision: From principle, material architectures to system‐level integration

open access: yesFlexMat, EarlyView.
This review introduces the development and mechanism of electronic and ionic bio‐inspired vision devices respectively. Then, it explores the impact of structure on bio‐inspired visual performance from the scale of intrinsic materials and device. Finally, it concludes that only by combining advanced software and technology can more complex vision ...

FAM107A loss facilitates TTK‐OPTN‐mediated mitophagy to drive docetaxel resistance in castration‐resistant prostate cancer

open access: yesInterdisciplinary Medicine, EarlyView.
In the progression of docetaxel resistance, downregulation of FAM107A releases its transcriptional repression of TTK, leading to TTK upregulation. TTK enhances the interaction and phosphorylation of OPTN. This activates mitophagy in tumor cells, facilitates clearance of damaged mitochondria, reduces intracellular reactive oxygen species accumulation ...
