Eocene and modern entomofauna differ-a Cretaceous-like larva in Rovno amber.

We report a 35 million-year-old lacewing larva from Ukrainian amber. This insect larva has a morphology up to now only known from 100 million-year-old amber. Therefore, this morphology survived more than 60 million years longer than previously assumed.

 Andersen & Dantas, gen. nov. (Diptera, Chironomidae, Orthocladiinae) from Brazil.

Andersen & Dantas, is erected based on the males of two species, Andersen & Dantas, from Jamanxim National Park, Pará State, Brazil, and Andersen & Dantas, from Ubajara National Park, Ceará State, Brazil. Both species have a comparatively short and wide head, with large eyes and short, five-segmented palps; a strong subapical seta on the ultimate flagellomere; scalpellate acrostichals; no setae on the wing veins except for one seta on the brachiolum; a long costal extension; and a large triangular anal point and a very long heel on the gonostylus. The systematic position of the new genus is briefly discussed.

Trajectories of Early Childhood Skill Development and Maternal Mental Health.

We investigate the impacts of a perinatal psychosocial intervention on trajectories of maternal mental health and child skills, from birth to age 3. We find improved maternal mental health and functioning (0.17 to 0.

Effect of a helium and oxygen mixture on physiological parameters of rats with cerebral arterial air embolism.

Cerebral arterial air embolism (CAE) is a serious and potentially dangerous condition that can interrupt the blood supply to the brain and cause stroke. One of the promising gas mixtures for emergency treatment of air embolism is an oxygen-helium mixture. We modeled CAE in awake rats by injecting air into the common carotid artery.

Expanding the Mesozoic Record of Early Brachyceran Fly Larvae, including New Larval Forms with Chimera-Type Morphologies.

Diptera are one of the four megadiverse groups of holometabolan insects. Flies perform numerous ecological functions, especially in their larval stages. We can assume that this was already the case in the past; however, fly larvae remain rare in most deposits.
