A glycoprotein (GP) which is immunochemically and biologically related to human prostatic acid phosphatase (PAP) has been isolated from human seminal plasma by ammonium sulfate precipitation followed by sequential concanavalin A:Sepharose 4B column, anion-exchange chromatography and gel filtration. The purified GP was shown to be homogeneous by disc- and sodium dodecyl sulfate: polyacrylamide g...

Introduction: Cervical cancer is the third most commonly diagnosed cancer worldwide. Pap smears and HPV vaccinations allow for prevention, diagnosis and improved treatment for cervical cancer. Concerns have been raised about decreased Pap smear compliance due to misconceptions about the role of HPV vaccinations. This study aimed to assess the compliance of, the knowledge about and the barriers ...

The aim of this study was to compare direct visual inspection (DVI) with Pap smear in diagnosis of precancerous lesion of cervix. A total of 1500 women were screened cytologically as well as clinically with direct visual inspection of cervix after application of acetic acid (DVI). A total of 1500 women were screened cytologically as well as clinically with direct visual inspection of cervix aft...

Abiotic stress, such as drought and high salinity, activates a network of signaling cascades that lead to the expression of many stress-responsive genes in plants. The Arabidopsis FIERY1 (FRY1) protein is a negative regulator of stress and abscisic acid (ABA) signaling and exhibits both an inositol polyphosphatase and a 3',5'-bisphosphate nucleotidase activity in vitro. The FRY1 nucleotidase de...

Pokeweed antiviral protein (PAP) belongs to the family of type I ribosome‑inactivating proteins (RIPs): Ribotoxins, which function by depurinating the sarcin‑ricin loop of ribosomal RNA. In addition to its antibacterial and antifungal properties, PAP has shown promise in antiviral and targeted tumor therapy owing to its ability to depurinate viral RNA and eukaryotic rRNA. Several PAP genes are ...

Purple acid phosphatases (PAPs) are binuclear hydrolases that catalyse the hydrolysis of a range of phosphorylated substrates. Human PAP is a major histochemical marker for the diagnosis of osteoporosis. In patients suffering from this disorder, PAP activity contributes to increased bone resorption and, therefore, human PAP is a key target for the development of anti-osteoporotic drugs. This ma...

The mechanism by which bi-and trivalent cations affect human liver phosphatidatephosphohydrolase (PAP) activity was investigated. Bivalent cations up to 1 mM increased PAP activity whereas at higher concentrations the activity of the enzyme decreased. The stimulatory concentration for trivalent cations such as Al3+ and Cr3+, however, was much lower being 2 m M and 1 m M, respectively. All catio...

BACKGROUND The pancreatitis-associated protein (PAP) is increased in the serum of active inflammatory bowel disease (IBD) patients and its levels seem to be correlated with disease activity. Our aim was to evaluate the usefulness of serum and fecal PAP measurements to predict relapse in patients with inactive IBD. MATERIALS AND METHODS We undertook a 12-month prospective study that included 6...

We have previously reported the purification of a 37-kd platelet-agglutinating protein (PAP p37) from the plasma of a patient with thrombotic thrombocytopenic purpura (TTP) that was shown to be present in a subset of TTP patients. The platelet agglutination induced by PAP p37 has been shown to be inhibited by IgG from normal human adults and the same TTP patient after recovery. To elucidate the...
