Cirrhosis is a common and terminal outcome of many chronic liver conditions. A urinary metabonomic study using gas chromatography–mass spectrometry (GC–MS) and ultra performance liquid chromatography time-of-flight mass spectrometry (UPLC–TOFMS) was carried out to elucidate the pathophysiological basis of posthepatitis B cirrhosis in 63 posthepatitis B cirrhosis patients and 31 health controls. Urinary metabolic profile and corresponding differential metabolites associated with Child-Pugh (CP) grading of liver function were characterized, in addition to the blood routine, liver, and renal function tests. Multivariate statistical tools including principal component analysis (PCA) and orthogonal partial least-squares-discriminant analysis (OPLS-DA) were employed in the metabolite analysis along with a univariate statistical method, Wilcoxon–Mann–Whitney test. The alterations of differential metabolites contributing to the intergroup variation between healthy controls and cirrhotic patients, and among cirrho...

The successful applicability of gene therapy approaches will heavily rely on the development of efficient and safe nonviral gene delivery vectors, for example, cell-penetrating peptides (CPPs). CPPs can condense oligonucleotides and plasmid DNA (pDNA) into nanoparticles, thus allowing the t ... more
Dendrimers feature a defined number of terminal groups that may bind RNA or be functionalized with bioactive molecules. These competing uses of terminal groups may create an impasse if the requisite density of ligands depletes the number of terminal groups for binding sufficient RNA, or vic ... more
The development of clay bionanocomposites requires processing routes with nanostructural control. Moreover, moisture durability is a concern with water-soluble biopolymers. Here, oriented bionanocomposite coatings with strong in-plane orientation of clay platelets are for the first time pre ... more
Scientists are reporting discovery of a potential biochemical basis for the apparent cancer-fighting ability of broccoli and its veggie cousins. They found for the first time that certain substances in the vegetables appear to target and block a defective gene associated with cancer. Their ... more
Scientists in Japan are reporting development of a faster, less expensive version of the fabled polymerase chain reaction (PCR) a DNA test widely used in criminal investigations, disease diagnosis, biological research and other applications. The new method could lead to expanded use of PCR ... more
Researchers at Rice University in Texas have developed a new approach to fighting cancer, based on nanoscale particles that can both detect and destroy cancerous cells. The report appears in the American Chemical Society's journal Nano Letters. Current molecular imaging approaches only dete ... more
