1. Peptidomic analysis of the venom of the solitary bee Xylocopa appendiculata circumvolans
Abstract Background: Among the hymenopteran insect venoms, those from social wasps and bees - such as honeybee, hornets and paper wasps - have been well documented. Their venoms are composed of a number of peptides and proteins and used for defending their nests and themselves from predators. In contrast, the venoms of solitary wasps and bees have not been

2. Relationship among Apis mellifera L. stings, swarming and climate conditions in the city of Rio Claro, SP, Brazil
The presence of bees (Apis mellifera L.) in urban areas has increased in recent years due to environmental disturbances caused by humans. Bee migration to cities may provoke serious accidents, since some people present allergic reactions to their venoms. In Rio Claro city, São Paulo state, Brazil, the number of calls to the fire brigade for removal of bee s

3. Identification of proteins from honeybee venom (Apis mellifera L.) immunoreactives to antivenom serum through a proteomic approach / Identificação das proteínas do veneno de abelhas africanizadas (Apis mellifera L.) imunoreativas ao soro antiveneno por abordagem proteômica
O estudo de venenos de artrópodes é de grande interesse para melhorar os tratamentos contra envenenamentos e oferece uma ótima ferramenta para melhor compreensão dos sistemas nervoso e imunológico, coagulação sanguínea e respostas inflamatórias. As abelhas são um dos animais venenosos mais estudados e a elucidação do seu proteoma é de interesse

4. Hymenoptera venom review focusing on Apis mellifera
Hymenoptera venoms are complex mixtures containing simple organic molecules, proteins, peptides, and other bioactive elements. Several of these components have been isolated and characterized, and their primary structures determined by biochemical techniques. These compounds are responsible for many toxic or allergic reactions in different organisms, such as

5. Low concentrations of indomethacin inhibit phospholipase A2 of rabbit polymorphonuclear leukocytes.
Inhibition of prostaglandin synthesis by indomethacin, a drug with anti-inflammatory properties, has been attributed to its action on fatty acid cyclooxygenase. However, prostaglandin synthesis would also be inhibited if precursor fatty acids were not supplied. We find that indomethacin inhibits phospholipase A2 (phosphatide 2-acylhydrolase, EC 3.1.1.4) of r

6. Phospholipase A2 activity can protect renal tubules from oxygen deprivation injury.
During hypoxic or ischemic renal tubular injury, phospholipase A2 (PLA2) induces membrane deacylation, causing fatty acid accumulation and phospholipid breakdown. Because these changes can compromise cellular integrity, PLA2 activity has been widely proposed as a critical mediator of hypoxic renal tubular injury and, hence, of ischemic acute renal failure. T
