Using a novel PCR approach, we have cloned a cDNA encoding the entire high molecular weight tau molecule from rat dorsal root ganglia. The resulting 2080 bp cDNA differs from low molecular weight rat brain tau by the insertion of a novel 762 bp region (exon 4a) between exons 4 and 5. This cDNA clone is identical in sequence with a high molecular weight tau (HMW) cDNA from rat PC12 tumor cells a...

1. By the double immunodiffusion technique, highly purified high molecular weight urokinase (HMW-UK; MW 53, 000, 124, 000 IU/mg protein) and low molecular weight urokinase (LMW-UK; MW 32, 000, 230, 000 IU/mg protein) revealed the same antigenicity, and their fibrinolytic activities were equally quenched with rabbit antisera against both enzymes. 2. Specific antisera against the functionally-act...

To broaden the specificity of the Abs recognizing human melanoma-associated Ags (MAAs), we have isolated human single-chain fragment of the V region (scFv) fragments by panning the synthetic phage Ab library (#1) with the human melanoma cell lines S5 and SK-MEL-28. All of the isolated scFv fragments reacted with the mouse mAb defined high molecular weight melanoma-associated Ag (HMW-MAA). scFv ...

Antibiotic resistance is threatening to make gonorrhoea untreatable. Point-of-care (POC) tests that detect resistance promise individually tailored treatment, but might lead to more treatment and higher levels of resistance. We investigate the impact of POC tests on antibiotic-resistant gonorrhoea. We used data about the prevalence and incidence of gonorrhoea in men who have sex with men (MSM) ...

BACKGROUND Polylactic-co-glycolic acid (PLGA) nanoparticles have been used to increase the relative oral bioavailability of hydrophobic compounds and polyphenols in recent years, but the effects of the molecular weight of PLGA on bioavailability are still unknown. This study investigated the influence of polymer molecular weight on the relative oral bioavailability of curcumin, and explored the...

A new method of sequential extraction of proteins followed by quantitative and qualitative determination by reverse-phased high-performance liquid chromatography (RP-HPLC) was used to analyse the effect of environmental conditions (3N fertilisation rates, two varieties, two sites and two growing seasons) on quantitative and qualitative variation of wheat storage proteins. The results showed tha...

BACKGROUND Adiponectin is shown to be inversely associated with development and progression of various cancers. We evaluated whether adiponectin level was associated with the prevalence and histological grade of hepatocellular carcinoma (HCC), and liver fibrosis in patients with hepatitis C virus (HCV) infection. METHODS A case-control study was conducted on 97 HCC patients (cases) and 97 pat...

BACKGROUND Studies have reported an increase in median Lipoprotein (Lp) (a) in patients with high molecular weight (HMW) apolipoprotein (apo) (a) isoforms and renal impairment. Some studies identify Lp (a) levels as a risk factor for vascular disease in renal failure whilst others have demonstrated an association with apo (a) isoform type and vascular disease. METHODS A total of 239 patients ...

Fibrin degradation results in the formation of fibrin degradation products (FDPs) of different molecular weights, which include D-dimer. Commercial D-dimer assays recognize multiple forms of FDP with different specificity. As a result, the absence of an international D-dimer standard and the marked discrepancy in the D-dimer values in the same samples measured by assays from different manufactu...

D hordein, a prolamin storage protein of barley endosperms, is highly homologous to the high molecular weight (HWM) glutenin subunits, which are the major determinants of bread-making quality in wheat flour. In hexaploid wheat (AABBDD), each genome contains two paralogous copies of HMW-glutenin genes that encode the x- and y-type HMW-glutenin subunits. Previously, we reported the sequence analy...
