Extracorporeal ultrasound-guided high intensity focused ultrasound therapy: Present limitations
Extracorporeal ultrasound-guided high intensity focused ultrasound (USgFU) ablates solid lesions non-invasively. Limitations manifested in preclinical and clinical trials are discussed in brief. The ablation efficiency (necrosis rate) is low. Tissue responses are monitored in real time during USgFU treatment, based upon the appearance of hyperecho within the insonated volume. However, hyperecho does not necessarily...

New antimicrobial peptides purified directly from Bullacta exarata
Endogenous antimicrobial peptides are exciting candidates as new antibacterial agents due to their broad antimicrobia spectra, highly selective toxicities and the difficulty for bacteria to develop resistance to these peptides. Marine invertebrates, which rely solely on innate immune system for host defense, are the spectacular resources for new antimicrobial compounds. In order to seek for new effective...

A modified arithmetical method of Reed and Muench for determination of a relatively ideal median lethal dose (LD50)
Reed L.J. and Muench H. introduced arithmetical method for determination of median lethal dose (LD50) in 1938. Since then the same method has not been revised for better precision and accuracy. Therefore this paper examined the possibility of modifying the method and arrived at logical conclusion. The possible modifications involve calculating per cent of test animals both that died and survived at all the test dose...
