Primary effusion lymphoma (PEL) is a rare type of non-Hodgkin lymphoma that mainly occurs in immunodeficient patients and is associated with infection by human herpes virus-8 (HHV-8). It develops in serous cavities, causing lymphomatous effusions in the absence of lymphadenopathy or organomegaly.1,2 Previous studies suggested that PEL occurs almost exclusively in HIVinfected patients. It was fi...

Complex states in glasses can be neatly expressed by the potential energy landscape (PEL). However, because PEL is highly multi-dimensional it is difficult to describe how the system moves around in PEL. Here we demonstrate that it is possible to predict the evolution of macroscopic state in a metallic glass, such as ageing and rejuvenation, through a set of simple equations describing excitati...

BACKGROUND Kaposi sarcoma-associated herpesvirus (KSHV) is the etiologic agent of primary effusion lymphomas (PEL). PEL cell lines infected with KSHV, but negative for Epstein-Barr virus have a tumorigenic potential in non-obese diabetic/severe combined immunodeficient mice and result in efficient engraftment and formation of malignant ascites with notable abdominal distension, consistent with ...

Fractional pel motion compensation generally improves coding efficiency due to more precise motion accuracy and low path filtering effect in generating image at fractional pel positions. In H.264, quarter pel motion compensation is applied, where image at half pel position is generated by 6 tap Wiener filter. And the adaptive interpolation filter technique, which adaptively changes filter chara...

Biofilm formation is a complex, ordered process. In the opportunistic pathogen Pseudomonas aeruginosa, Psl and Pel exopolysaccharides and extracellular DNA (eDNA) serve as structural components of the biofilm matrix. Despite intensive study, Pel's chemical structure and spatial localization within mature biofilms remain unknown. Using specialized carbohydrate chemical analyses, we unexpectedly ...

A dynamic mathematical model has been developed and validated to describe the synthesis of pectate lyases (Pels), the major virulence factors in Dickeya dadantii. This work focuses on the simultaneous modeling of the metabolic degradation of pectin by Pel enzymes and the genetic regulation of pel genes by 2-keto-3-deoxygluconate (KDG), a catabolite product of pectin that inactivates KdgR, one o...

Pseudomonas aeruginosa is a Gram-negative bacterium associated with nosocomial infections and cystic fibrosis. Chronic bacterial infections are increasingly associated with the biofilm lifestyle in which microcolonies are embedded in an extracellular matrix. Screening procedures for identifying biofilm-deficient strains have allowed the characterization of several key determinants involved in t...

Hypothesis Anthocyanins possess well-known biological effects and suppress DNA damage induced by therapeutic topoisomerase poisons. Our study focusses on the modulatory effects of anthocyanidins-malvidin (MAL) and pelargonidin (PEL)-on topoisomerase II poison mitoxantrone (MXT)-induced cytotoxicity and genotoxicity in in vitro and in vivo conditions. Study design HepG2 cells were treated with M...

BACKGROUND The International Staging System for multiple myeloma has increased the importance of accurate measurement of serum albumin. Two common albumin assays, bromcresol green (BCG) and agarose gel protein electrophoresis (PEL), frequently yield discordant results, creating confusion regarding which assay is superior for use in myeloma. METHODS We measured albumin by BCG on a Roche Modula...

The peculiar site of development of primary effusion lymphoma (PEL) highlights a specific role of body cavities in the pathogenesis of this neoplasia. We used a xenograft murine model of PEL to characterize the contribution of the host microenvironment to PEL growth. The activity of a murine (ie, host-specific) interferon-alpha(1) (IFN-alpha(1))-expressing lentiviral vector (mIFN-alpha(1)-LV) w...
