Although the histopathogenetic process of keratin pearls is still poorly understood, acceleration of keratinization in squamous cell carcinoma (SCC) cells may represent one possible therapeutic avenue. Based on our histopathological observations, we have hypothesized that SCC cells are keratinized by phagocytosis of extravasated erythrocytes. To confirm this hypothesis, we firstly examined imma...

We present an approach for the design and implementation of embedded real-time software running on a distributed platform. The approach consists of a high-level specification layer instantiated by Giotto programs and a low-level verification and execution layer instantiated by Schedule carrying code (SCC). We explain a methodology in which several code suppliers, coordinated by a resource manag...

IntroductionThis study aimed to analyse cervical lymphocytic populations in HIV+ and HIV− patients correlate different lesions with HIV viral load presence of high-risk HPV types.Material methodsA total 132 histological specimens from 40 72 were evaluated for CD4+ CD8+ T cell distribution, types, peripheral blood CD4+/CD8+ ratio.ResultsHigh-grade squamous intraepithelial (HSIL) carcinoma (SCC) ...

Human papilloma virus (HPV) is an etiologic agent in a subset of oropharyngeal squamous cell carcinomas (SCCs). The aim of this study was to sub-classify SCC of the oropharynx based upon histologic features into nonkeratinizing (NK) SCC, keratinizing (K) SCC, and hybrid SCC, and determine the frequency of HPV and patient survival in each group. Patients with oropharyngeal SCC with a minimum of ...

Abstract SCC of a series AFA stainless steels with different Al and Nb contents were studied in supercritical CO 2 by SSRT. The results show that element plays precipitation strengthening on the mechanical properties, while it shows few effects corrosion properties. surface oxide film Al-free material only consisted amorphous Cr O 3 Cr-rich spinel. With addition Al, layers are formed significan...

Bit-interleaved coded modulation with iterative detection for MIMO systems demands an efficient APP detector that delivers soft information about the coded bits. The list-sequential detector is a reduced-complexity approximation to an exhaustive APP detector. It uses a tree search employing the stack algorithm to find dominant terms of the log-likelihood ratio. The commonly used symbol-by-symbo...

BACKGROUND The cytology of oral squamous cell carcinoma (SCC) is challenging because oral SCC cells tend to be well differentiated and lack nuclear atypia, often resulting in a false negative diagnosis. The purpose of this study was to establish practical cytological parameters specific to oral SCCs. METHODS We reviewed 123 cases of malignancy and 53 of non-neoplastic lesions of the oral muco...

Distributed storage systems take advantage of the network, storage and computational resources to provide a scalable infrastructure. But in such large system, failures are frequent and expected. Data replication is the common technique to provide fault-tolerance but suffers from its important storage consumption. Erasure coding is an alternative that offers the same data protection but reduces ...

Systems for the digital transmission of voice have traditionally been xed rate in anti-jam situations. This design severely limits the potential of the communication system in the case of voice since compression of speech is a lossy process. Bit errors in the transmission of voice coded speech cause degradation which can be compensated for in several ways. The standard method is to trade o chan...
