From balloons to rubber bands, things always break faster when stretched. Or do they? University of Illinois scientists studying chemical bonds now have shown this isn't always the case, and their results may have profound implications for the stability of proteins to mechanical stress and the design of new high-tech polymers. http://www.physorg.com/news164457846.html Chemistry Wed, 17 Jun 2009 12:20:02 EST news164457846 Haemorrhoids are considered one of the most frequent diseases of the anal region with high prevalence (nearly 50% of proctological visits in a colorectal unit), involving any age and affecting both sexes. Numerous modalities and techniques have been developed to treat symptomatic hemorrhoids ranging from simple dietary measures and bowel habit regulation, through a number of non-operative procedures, to different techniques of excision of diseased analCushions. The vast amount of treatment options means none are close to perfection. Nonsurgical methods aim at tissue fixation (sclerotherapy, cr yotherapy, photocoagulation, laser), or fixation with tissue excision [rubber band ligation (RBL)]. RBL is considered the most widely used procedure, and it offers the possibility to resolve hemorrhoidal disease without the need for hospitalization or anaesthesia, and with lower incidence of complications. http://www.physorg.com/news147366439.html Medicine & Health Mon, 01 Dec 2008 15:07:19 EST news147366439
