Speaking of backgrounds, these photos of Anna Roggenburk and Maddie Lynch are the two best OTZ photos of the season. If the background of these photos had been a rusty fence with cars in the parking lot , then these photos become simply "good". The background is extremely important. This is one reason why it was very important that OTZ be able to shoot with more "freedom" at States. As many of you know, OTZ had been prohibited by the OHSAA from selling photos from States and from even posting more than four States photos on the same page of this web site. It was an absurd restriction that was finally resolved last spring before the boys season.
Prostaglandins are synthesized from arachidonate(Lipoxygenase which catalyze the dioxygenation of polyunsaturated fatty acids) in the cell membrane by the action of phospholipase A2. Cyclooxygenase and lipoxygenase pathways, compete with one another to form prostaglandins(as well as thromboxane or leukotriene-leukotriene being a bronchial stimulator),
In the cyclooxygenase pathway, the prostaglandins D, E and F plus thromboxane and prostacyclin are made. Thromboxanes are made in platelets and cause constriction of vascular smooth muscle and platelet aggregation
Leukotrienes are made in leukocytes and macrophages via the lipoxygenase pathway. They are potent constrictors of the bronchial airways. They are also important in inflammation and hypersensitivity reactions as they increase vascular permeability.
