This paper describes the first record of Sejida (= Sejina) family Sejidae (superfamily Sejoidea) from Burmese amber, based on deutonymphs. Specimens were found in amber piece along with a wasp (Hymenoptera: Scelionidae), flies (Diptera: Ceratopogonidae) and thrips (Thysanoptera: Adiheterothripidae). traces back to mid-Cretaceous (ca. 100 Ma) represents not only oldest valid Mesostigmata, but it...

Amber is a fossilized tree resin that ranges in age from the Carboniferous to Cenozoic. It occurs globally Arctic Antarctica. As petrifies and turns into amber, it can enclose preserve other materials. with inclusions help reconstruct past biodiversity ecosystems. Some amber contains fossils representing oldest most detailed records of critical evolutionary traits or markers. Inclusions even ca...

Amber, a plant resin, exhibits an anti-stress effect and is used in traditional medicine. Recently, it has been speculated that amber may possess anti-depressive effect. However, there no evidence to support this efficacy. Thus, study investigated the oxidative-stress-ameliorating effects of extract mice subjected restraint stress. Mice were treated with (25 50 mg/kg, p.o.) bupropion (10 as pos...

Pondweed bugs (Hemiptera: Mesoveliidae), considered a sister group to all other Gerromorpha, are exceedingly rare as fossils. Therefore, each new discovery of a fossil mesoveliid is of high interest, giving new insight into their early evolutionary history and diversity and enabling the testing of their proposed relationships. Here, we report the discovery of new mesoveliid material from Spanis...

Investigation of fossils in lower Eocene Fushun amber from China keeps proving to be of major importance for understanding Eocene Euro-Asian insect diversity and distribution. Three new species of predatory biting midges in the fossil genera Mantohelea and Gedanohelea are described. Mantohelea sinica n. sp., Gedanohelea fushunensis n. sp. and Gedanohelea liaoningensis n. sp. from Eocene Fushun ...

All light is not equal: blue wavelengths are the most potent portion of the visible electromagnetic spectrum for circadian regulation. Therefore, blocking blue light could create a form of physiologic darkness. Because the timing and quantity of light and darkness both affect sleep, evening use of amber lenses to block blue light might affect sleep quality. Mood is also affected by light and sl...

Serratia entomophila and Serratia proteamaculans cause amber disease in the grass grub Costelytra zealandica (Coleoptera: Scarabaeidae), an important pasture pest in New Zealand. Larval disease symptoms include cessation of feeding, clearance of the gut, amber coloration, and eventual death. A 115-kb plasmid, pADAP, identified in S. entomophila is required for disease causation and, when introd...

Aquaporins are integral membrane proteins from a larger family of major intrinsic proteins that formpores in the membrane of biological cells. Aquaporins form tetramers in the cell membrane with eachmonomer acting as a water channel.In this research, the AQP4 tetramer was modeled from its PDBstructure file, then, we have performed the intraction of aquaporin4 in different temperatures (298k,300...

Nucleic acid force fields have been shown to reproduce structural properties of DNA and RNA very well, but comparative studies with respect to thermodynamic properties are rare. As a test for thermodynamic properties, we have computed hydration free energies and chloroform-to-water partition coefficients of nucleobases using the AMBER-99, AMBER-gaff, CHARMM-27, GROMOS-45a4/53a6 and OPLS-AA forc...
