Acetals derived from racemic 1,3-alkanediols undergo kinetic resolution in chiral oxazaborolidinone-mediated ring-cleavage reaction with nucleophiles such as enol silanes and allylic silanes. Enantioselectivity of the reaction is affected by nucleophiles, the N-sulfonyl groups of oxazaborolidinones, ...
An allergic reactionis the body's way of responding to an "invader." When the body senses a foreign substance, called an antigen, the immune system is triggered. The immune system normally protects the body from harmful agents such as bacteria and toxins. Its overreaction to a harmless substa...
Although most prescription medications are safe for use, some patients have an abnormal immune system that reacts poorly with certain drugs.Patients who have a sulfa allergy, for example, should not take the medication Bactrim DS because they will develop an allergic reaction to one of the compou...
A quick reaction is an indicator of the severity of the reaction (local or systemic Anaphylaxis) Mediated by antibodies...IgE Releases histamine TQ! Antigens: Antibiotics or other drugs, bee stings, anesthetics, food products Type I Severe Immediate Allergic Reaction that appears in previously sens...
Some bioactive agents include but are not limited to: antibiotics such as tobramycin, entamycin, and vancomycin; clotting factors such as Factors I-VIII, thrombin, and fibrinogen; cytokines for example basic fibroblast growth factor (bFGF), platelet derived growth factor (PDGF), vascular endothelial...
With all symptoms you just described it is quite possible that you have allergic reaction on narcotic pain meds. Rash and breathlessness are common sings of allergic reaction. However you can not check this. What did your doctor say? Did you tell him/her about these reactions (meaning rash ...
When I was twenty, I had an allergic reaction to a sulfa antibiotic. I broke out in itchy hives while I was taking the sulfa, but the hives went away as soon as I stopped taking it. I had no other symptoms nor lasting effects. I don’t recall whether or not I took Benadryl to ...
in patients with severe allergic responses to sulfonamide antibiotics, the risk of severe reaction with other sulfa-containing drugs such as acetazolamide was thought to outweigh potential benefits. however, recent studies of the chemical structure and mechanisms of immune response to these drugs suggest...
