A problem basic to molecular genetics involves the explanation of a mutation brought about by a base alteration in only one of the two DNA strands. Considering a semiconservative model of DNA replication ( MESELSON and STAHL 1958) one would expect stable alterations to cause a mutation in one half the progeny of a cell carrying only one set of genetic information. However, frequently pure mutan...

Bioadhesives In article 2203404 by Nasim Annabi, Ali Khademhosseini, and Paul S. Weiss co-workers, an efficient chemical route for mussel-inspired functionalization of natural biomacromolecules is developed to enhance sutureless sealing surgical wounds. Compared standard catechol functionalization, poly(catechol) modification gelatin leads injectable bioglues with rapid gelation hemorrhage cont...

BACKGROUND Antimicrobial agents have been used as a chemotherapeutic agent to improve oral health. This in vitro study was carried out to determine the antimicrobial activity of ten Iranian-made toothpastes against commonly found bacteria in the oral cavity. METHODS The microorganisms used in this study were Streptococcus mutans, Streptococcus sanguis, Actinomyces viscosus and Candida albican...

This paper illustrates four bronzeLevantine fenestrated axes dating back from the Early Bronze IVB (2200-2000/1950 BC)to Middle I(2000/1950-1800 BC)preserved in collection of British Museum.1The study gets underway some recent discoveries (‘Enot Shumi, Sana’iye, al-Nasim) and takes opportunity to re-analyze corpus Levantine axes, update it by defining diagnostic chronological characteristics, h...
