background: leukoplakia is a common, potentially premalignant lesion with malignant transformation rate from 1 to 17% with highest transformation rate for the lesions on the floor of the mouth, soft palate and tongue. one of the main etiological factors is consuming areca nut and its commercial preparations which generate high levels of reactive oxygen species during their metabolism. so the ai...

To experiment properly, scientists from many research areas need large sets of real world data. Information retrieval scientists for example often need to evaluate their algorithms on a dataset or a gold standard. The availability of these datasets often is insufficient and authors with the same goal do not evaluate their approaches on the same data. To make research results more transparent an...

Background: Areca nut (Areca catechu Linn.) is the seed of fruit oriental palm that commonly used among Southeast Asian communities. Chrysanthemum (Dendrathema grandiflora) a flowering plant originating from East Asia and dominantly grows in China. Both these plants have strong antioxidant activities. To investigate m...

Interleukin-10 (IL10) is an immunosuppressive cytokine which may facilitate carcinogenesis by down-regulating interferon-gamma production and supporting tumor escape from the immune response. Polymorphisms within the promoter of IL10 gene may not only contribute to differential IL10 expression levels among individuals but also to oral cancer susceptibility. In this hospital-based study, the ass...

Oral submucous fibrosis (OSF), regarded as a precancerous condition, is characterized by juxta-epithelial inflammatory reaction followed by fibro-elastic change in the lamina properia and epithelial atrophy. The pathologic mechanisms of OSF still need to be further clarified. In the study, we investigated the functional expression of SSEA-4, which is a well-known stemness marker, in myofibrobla...

Oral submucous fibrosis (OSF) is a high-risk precancerous condition of the oral cavity. Areca nut chewing is its key etiologic factor, but the full pathogenesis is still obscure. In this study, microarray analysis was used to characterize the mRNA changes of 14,500 genes in four OSF and four normal buccal mucosa samples to identify novel biomarkers of OSF. Five candidate genes with the most dif...

Natural fibers are gaining the interest of scientist and engineering in packaging, low cost housing and other general applications. In the present study, adhesive tensile and moisture absorption properties of randomly distributed areca fibre and maize powder reinforced urea formaldehyde composites has been investigated. Composites were prepared by hydraulic hot press at 150C and 100 bar pressur...

This investigation is primarily concerned with the effect of fly ash, basalt powder, and tungsten carbide (WC) on mechanical, microstructural, tribological behaviour areca fiber-reinforced composites. The fillers (5–10 wt. %) were included fiber epoxy reinforced In comparison to composites without fillers, inclusion WC increased tensile strength by 33–48.2 MPa. an A2 composite containing (20 %)...

ABSTRACTPinang Yaki (Areca vestiaria) is one of the plants that grows in North Sulawesi area, precisely on slopes Mount Soputan, Mahawu, Ambang, and Bogani Nani Wartabone National Park, which a type wild palm, turns out to have multifunctions (Simbala, 2007). The people (Mongondow Minahasa tribes) usually use this plant empirically cure various diseases such as diabetes diarrhea 2006). This stu...
