Involvement of the Endothelin Receptor Type A in the Cardiovascular Inflammatory Response Following Scorpion Envenomation.

Elevated levels of endothelin-1 (ET-1) were recorded in sera of scorpion sting patients. However, no studies focused on the mechanism of ET-1 involvement in the pathogenesis of scorpion envenomation, particularly in the cardiovascular system which is seriously affected in severe cases of scorpion stings. Inflammation induced by () scorpion venom in the heart together with the aorta was studied in mice pretreated with a specific A ETA-R) inhibitor.

Development of a new approach of immunotherapy against scorpion envenoming: Avian IgYs an alternative to equine IgGs.

Antivenom treatment has been largely used against scorpion stings. Despite their efficacy, the use of mammalian antivenoms may cause adverse effects due to the immune system activation. IgYs from hyperimmunized laying hens against venoms could be a promising alternative to equine IgGs due to the various benefits that these antibodies can provide.

Role of angiotensin II and angiotensin type-1 receptor in scorpion venom-induced cardiac and aortic tissue inflammation.

Scorpion stings are mainly associated with cardiovascular disturbances that may be the cause of death. In this study, the involvement of angiotensin II (Ang II) in cardiac and aortic inflammatory response was studied. Mice were injected with Androctonus australis hector (Aah) scorpion venom (0.

Occupation and risk of lymphoma: a multicentre prospective cohort study (EPIC).

Objectives: Evidence suggests that certain occupations and related exposures may increase the risk of malignant lymphoma. Farming, printing and paper industry, wood processing, meat handling and processing, welding, shoe and leather manufacturing and teaching profession are among the categories that have been implicated in previous studies. The relationship between occupation and malignant lymphoma has been investigated in a large European prospective study.
