Kaposi's sarcoma (KS) develops in a variety of clinical states and is the most common tumor seen in patients with HIV-1 infection. KS develops as a multifocal mucocutaneous disease with subsequent spread to visceral organs, and it has been argued to be a benign proliferation caused by its multifocality at initial presentation, lack of aneuploidy, and spontaneous regression upon withdrawal of im...
The knowledge of the soil saturated hydraulic conductivity (Ks) is essential for irrigation management purposes and for hydrological modelling. Several attempts have been done to estimate Ks in base of a number of soil parameters. However, a reliable enough model for qualitative Ks estimation based on the expert assessment of field characteristics had not been developed up to date. Five field c...
Recent evidence suggesting vascular endothelial growth factor-C (VEGF-C), which is a regulator of lymphatic and vascular endothelial development, raised the question whether this molecule could be involved in Kaposi's sarcoma (KS), a strongly angiogenic and inflammatory tumor often associated with infection by human immunodeficiency virus-1. This disease is characterized by the presence of a co...
Purpose Synthesis of keratan sulfate (KS) relies on coordinated action of multiple enzymes, including the N-acetylglucosamine-transferring enzyme, β-1,3-N-acetylglucosaminyltransferase-7 (β3GnT7). A mouse model deficient in β3GnT7 was developed to explore structural changes in KS and the extracellular matrix (ECM; i.e., the corneal stroma), elucidate the KS biosynthesis mechanism, and understan...
Kaposi's sarcoma (KS) is the major AIDS-associated malignancy. It is characterized by the proliferation of spindle cells, inflammatory infiltrate, and aberrant angiogenesis caused by Kaposi's sarcoma herpesvirus (KSHV) infection. Small GTPase Rac1, an inflammatory signaling mediator triggering reactive oxygen species (ROS) production by NADPH-oxidases, is implicated in carcinogenesis and tumor ...
A variety of assays for the diagnosis human herpesvirus 8 (HHV-8) infection have been reported. We compared several such assays with a panel of 88 specimens from human immunodeficiency virus (HIV)-infected patients with Kaposi's sarcoma (KS) (current-KS patients; n = 30), HIV-infected patients who later developed KS (later-KS patients; n = 13), HIV-infected patients without KS (no-KS patients; ...
Kaposi's sarcoma (KS) in general, and acquired immunodeficiency syndrome-related KS (AIDS-KS) in particular, is a highly invasive and intensely angiogenic neoplasm of unknown cellular origin. We have recently established AIDS-KS cells in long term culture and reported the development of KS-like lesions in nude mice inoculated with these cells. Here, we have examined the in vitro invasiveness of...
Nisin (50 microg/ml), EDTA (0.02 M, disodium salt), sodium lactate (NaL, 2%), and potassium sorbate (KS, 0.02%) were tested individually and in various combinations as sanitizer treatments for reducing Salmonella on whole and fresh-cut cantaloupe. Whole cantaloupe and fresh-cut pieces were inoculated with a five-strain cocktail of Salmonella to give 4.76 +/- 0.23 log CFU/cm2 and 3.42 +/- 0.13 l...
We present a measurement of the branching ratio BR(K → π±e∓ν̄(ν)) performed using the KLOE detector. KS-mesons are produced in the reaction e +e− → φ → KSKL at the DAΦNE collider. In a sample of ∼5 × 10 6 KS-tagged events we find 624± 30 semileptonic KS decays. Normalizing to the KS→π +π− count in the same data sample, we obtain BR(KS → πeν)= (6.91 ± 0.37) × 10 −4, in agreement with the Standard...
Klinefelter syndrome (KS) (47,XXY) is the most common male sex chromosome aneuploidy. Diagnosis and clinical supervision remain a challenge due to varying phenotypic presentation and insufficient characterization of the syndrome. Here we combine health data-driven epidemiology and molecular level systems biology to improve the understanding of KS and the molecular interplay influencing its como...
