the calcifying odontogenic cyst (coc) is a rare odontogenic cyst. only 2% of all odontogenic cysts and tumors are coc. coc associated with odontoma (cocao) reported in 24% of cocs. cocao presents a greater incidence in female, with a ratio of 2 to 1. the highest incidence of cocao occurs during the second decade with a mean age of 16 years, most frequently occurring in the maxilla (61.5%). here...

An audacious theory proposes the existence of a novel form of life—the nanobacteria (NB)—that is quite different from the ones already known, but is capable of infecting and damaging other beings, thus qualifying them as new agents of emerging infectious diseases. The theory is no less revolutionary than the famous germ theory of disease, which was put on solid ground by the efforts of Pasteur ...

Although the lower size limit of microorganisms was previously believed to be c. 0.2mm, there is evidence for the existence of microorganisms that can pass through 0.2mm-pore-size filters called ultramicrobacteria or nanobacteria. However, information on the phylogeny and biogeography of these bacteria is limited. We obtained 53 isolates of 0.2mm-passable bacteria from 31 samples collected at 2...

A solution-based strategy for fabrication of high dielectric constant (κ) nanocomposites for flexible organic field effect transistors (OFETs) has been developed. The nanocomposite was composed of a high-κ polymer, cyanoethyl pullulan (CYELP), and a high-κ nanoparticle, zirconium dioxide (ZrO2). Organic field effect transistors (OFETs) based on neat CYELP exhibited anomalous behavior during dev...

Haptophytes are an environmentally important phylum of eukaryotic phytoplankton, forming the second most abundant algal group after diatoms in recent estimates ocean biodiversity. phylogenetically and functionally diverse, including globally distributed bloom-forming calcifying species such as Emiliania Coccolithus, non-calcifying orders that may form components phytoplankton communities polar ...

A blue crab (Callinectes sapidus) expressed sequence tag project was designed for multiple purposes including discovery of genes for cuticular (exoskeletal) proteins, some of which may regulate mineralization. One of the expression libraries sequenced was from the hypodermis (the epithelium depositing the cuticle). RNAs used for cDNA synthesis were pooled from arthrodial and mid-dorsal hypoderm...
