conclusions p. gingivalis and p. intermedia could play a role in implant failure by changing the expression profiles of genes related to bone formation and resorption. results viability was reduced to 56.8% (p. gingivalis) and 52.75% (p. intermedia) at 1000 multiplicity. amongst 48 genes examined, expressions of bmper, smad1, il8 and nfrkb were found to be highly upregulated by both bacterial c...

Background: Viral infections such as Epstein-Barr virus and Herpes simplex virus may play a role in the pathogenesis of Behçet’s disease (BD). Interferons (INF) are natural defense mechanisms against viruses and inhibit their activities by enhancing major histocompatibility complex class I and cytokine expression. This study evaluated the efficacy of INF-α-2b on mucocutaneous lesions of BD. Met...

A key control point in the initiation of protein synthesis in mammalian cells is the recycling of eukaryotic initiation factor (eIF)-2 by the guanine nucleotide exchange factor eIF-2B. In mammalian cells, eIF-2B is a complex of five different subunits termed epsilon, delta, gamma, beta and alpha. To clone cDNAs for the beta subunit of rabbit eIF-2B, amino acid sequence data was first obtained a...

Chronic inflammatory airway diseases, such as bronchial asthma and chronic obstructive pulmonary disease, are common respiratory disorders worldwide. Exacerbations of these diseases are frequent and worsen patients' respiratory condition and overall health. However, the mechanisms of exacerbation have not been fully elucidated. Recently, it was reported that interleukin (IL)-17A might play an i...

Hemangiomas are benign tumors of the vascular endothelium and are the most common tumors of infancy. These tumors are characterized by an initial phase of rapid proliferation, which is followed, in most cases, by spontaneous involution. Although most lesions resolve without complication, there are some cases in which hemangiomas can be life threatening when occurring near a vital structure. Tre...

BACKGROUND Prostate cancer frequently metastasizes to bone. However, unlike many other tumors that produce osteolytic lesions, prostate cancer produces osteoblastic lesions through unknown mechanisms. In the current study, we explored the ability and mechanism of an osteotropic prostate cancer cell line (C4-2B) to induce mineralization. METHODS C4-2B cells were grown in promineralization medi...

Pharmacological studies suggest that A(2B) adenosine receptors mediate proinflammatory effects of adenosine in human mast cells in part by up-regulating production of Th2 cytokines and angiogenic factors. This concept has been recently challenged by the finding that mast cells cultured from bone marrow-derived mast cells (BMMCs) of A(2B) knockout mice display an enhanced degranulation in respon...

We take advantage of the Shiromizu et al. covariant formalism to find out brane properties originating from five dimensional bulk spacetime. Making a different choice for conformal factor $e^{-2b(z)}$ compared Estrada [24], we reach new solution with lot interesting properties, where $b(z) = ln(1/\sqrt{cosh2\mu z})$. The non-local tensor $E_{ab}$ rooted 5-dimensional Riemann gives an anisotropi...

Mucosal neuromas are a form of neurogenic tumour that arises in the oral cavity as a component of multiple endocrine neoplasia type 2b (MEN 2b). The syndrome is characterized with other features like tumors of the endocrine glands and skeletal abnormalities. Mutation at codon 918 of the RET protooncogene is a consistent feature among people affected with MEN 2. There are few reports describing ...
