The Law of Conservation of Mass dates from Antoine Lavoisier's 1789 discovery that mass is neither created nor destroyed in chemical reactions. In other words, the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction.
Antibiotic Gentamicin, when mixed with DePuy Orthopaedics bone cement products, may weaken the bond between cement and bone in joint replacement patients, and cause the prosthetic to slide off of the bone after the patient has suffered a great deal of pain and immobility.
Clindamycin is a lincosamide antibiotic. It is usually used to treat infections with anaerobic bacteria but can also be used to treat some protozoal diseases, such as malaria. It is a common topical treatment for acne, and can be useful against some methicillin-resistant Staphylococcus aureus (MRSA) infections.hese antibiotics exert their activity by binding to bacterial ribosomes and preventing the initiation of protein synthesis. Streptomycin binds to 30S subunit of the bacterial ribosome, specifically to the S12 protein which is involved in the initiation of protein synthesis.
