We examined complement-dependent cytotoxicity (CDC) by hexamer formation-enhanced CD20 mAb Hx-7D8 of patient-derived chronic lymphocytic leukemia (CLL) cells that are relatively resistant to CDC. CDC was analyzed in normal human serum (NHS) and serum from an individual genetically deficient for C9. Hx-7D8 was able to kill up to 80% of CLL cells in complete absence of C9. We conclude that the na...

Content Defined Chunking (CDC) is an important component in data deduplication, which affects both the deduplication ratio as well as deduplication performance. The sliding-window-based CDC algorithm and its variants have been the most popular CDC algorithms for the last 15 years. However, their performance is limited in certain application scenarios since they have to slide byte by byte. The a...

BACKGROUND/AIMS Our clinical experience and recent published literatures suggest that Clostridium difficile colitis (CDC) has become more common and potentially more pathogenic in recent years. The aim of study was to evaluate changes in the epidemiological features of CDC in hospitalized patients in Korea. METHODS We retrospectively reviewed all patients of CDC diagnosed at Kangnam St. Mary ...

Much of our understanding of the function and regulation of the Cdc14 family of dual-specificity phosphatases originates from studies in yeasts. In these unicellular organisms Cdc14 is an important regulator of M-phase events. In contrast, the Caenorhabditis elegans homolog, cdc-14, is not necessary for mitosis, rather it is crucial for G(1)/S regulation to establish developmental cell-cycle qu...

In several countries, surveillance of insect vectors is accomplished with automatic traps. This study addressed the performance of Mosquito Magnet® Independence (MMI) in comparison with those of CDC with CO2 and lactic acid (CDC-A) and CDC light trap (CDC-LT). The collection sites were in a rural region located in a fragment of secondary tropical Atlantic rainforest, southeastern Brazil. Limatu...

Septins are GTP-binding cytoskeletal proteins that contribute to cell polarity, vesicle trafficking, cytokinesis and cell morphogenesis. Here we have characterised the six septins encoded by the genome of the model filamentous fungus Neurospora crassa. Analysis of septin null mutants demonstrated that septins limit the sites of emergence of germ tubes and are important for septation and conidia...

Direction relations between extended spatial objects are important commonsense knowledge. Recently, Goyal and Egenhofer proposed a formal model, known as Cardinal Direction Calculus (CDC), for representing direction relations between connected plane regions. CDC is perhaps the most expressive qualitative calculus for directional information, and has attracted increasing interest from areas such...

Collecting duct carcinoma (CDC) is a rare renal neoplasm that is associated with poor prognosis due to its highly aggressive course and limited response to immuno- or chemotherapy. Histologically, CDC is defined as a subtype of renal cell carcinomas, but in some cases, it is difficult to differentiate from urothelial carcinomas (UC). Therefore the aim of this study was to determine genetic alte...

We tested bile acid oxazoline derivatives of chenodeoxycholic (CDC-OX), 7-ketolithocholic (7-KLC-OX), ursodeoxycholic (UDC-OX), and deoxycholic (DC-OX) as inhibitors of the 7-epimerization of the primary bile acids cholic acid (CA) and CDC in cultures of four species of bacteria and the human fecal flora. The organisms tested elaborate a 7 alpha- and/or 7 beta-hydroxysteroid dehydrogenase (HSDH...
