Background: To determine the efficacy of three different antiseptic solutions (Control group (I), Antibiotic solution – Neomycin and polymyxin (II), Chlorhexidine 0.4% (III), and povidone – iodine 10% (IV)) in disinfecting contaminated bone fragments. Methods: Under sterile conditions, the femora of 12 rabbits were removed and cut into six millimeter pieces. A total of 200 bone specimens were ...

Effective protocols are introduced for parthenogenesis activation in oocytes. Hydrostatic pressure can act as a mechanical stimulator that rearranges egg contents, leading to new structural or molecular combination. Alternatively, mechanical stimulation could stimulate a mechanically-gated process, such as opening or closing of stretch activated ion channels. This study, investigated the use of...
