Stallergenes Partners With Catalent and the Medical House for Commercialization of Adrenaline Autoinjector in Europe

...he safety and the ease-of-use for patients. The adrenaline autoinjector is designed for the emergency treatment of anaphylactic shock, mostly due to hymenoptera venom or food allergies, and for use by the patient himself or a relative in the event of an emergency. Catalent expects to submit the file of ADREF...

Emergency Treatment Found Wanting In Anaphylactic Reactions

...son, II, M.D., San Antonio, Texas, and colleagues, says that out of the 120 cases that resembled a systemic reaction, 59 of them were bitten by flying hymenoptera and 46 by fire ants. More dangerously, only 55 percent of them received injectible epinephrine or adrenaline and only 39 percent were referred t...

Trading energy for safety, bees extend legs to stay stable in wind

...ir jet. While Combes and Dudley only studied 10 species of euglossine bees, Combes says that this stabilizing behavior is likely to be seen across hymenoptera , the order of insects that includes bees, wasps, ants, and sawflies, and that turbulent airflow may decrease the flight performance of many other fly...

Insects' 'giant leap' reconstructed by founder of sociobiology

...bees, and wasps (Hymenoptera). Wilsons article surveys recent evidence that the high level of social organization called eusociality, found in some hymenoptera (and rarely in other species), is a result of natural selection on nascent colonies of species possessing features that predispose them to colonial li...

Researchers now able to look deep into heart to view triggers of a heart's beat

...the key steps in the evolution of social insects, therefore, may have been the development of a mechanism for making centrosomes from scratch. "The hymenoptera were probably derived from a species that had accessory nuclei, and in the evolution of haplodiploidy the accessory nuclei were co-opted as a way of b...

Haplodiploidy is found in many species of insects from the family hymenoptera , particularly ants , bees , and wasps .
