Future therapies for the treatment of dental decay have to consider the importance of preserving bacterial ecology while reducing biofilm adherence to teeth. A multi-species plaque-derived (MSPD) biofilm model was used to assess how concentrations of N-acetyl-l-cysteine (NAC) (0, 0·1, 1, 10%)
Acute otitis media, a polymicrobial disease of the middle ear cavity of children, is a significant public health problem worldwide. It is most frequently caused by encapsulated Streptococcus pneumoniae and nontypeable Haemophilus influenzae, although the widespread use of pneumococcal conjugate
The role of transcription factor NF-kappa B in the induction of cytokines and ICAM-1 upon stimulation with proinflammatory cytokines, IL-1 and tumor necrosis factor (TNF)-alpha was investigated in primary synovial fibroblasts obtained from patients with rheumatoid arthritis (RA). Nuclear
The antiproliferative effects of a Gingko biloba leaf extract to cells from tissues of the human oral cavity were studied. Toxicity to carcinoma HSC-2 cells was correlated with the prooxidative nature of the extract. G. biloba leaf extract generated reactive oxygen species (ROS) in cell culture
The antiproliferative and proapoptotic effects of pomegranate extract (PE), as correlated with its prooxidant activity, were studied. PE exerted greater antiproliferative effects towards cancer, than to normal, cells, isolated from the human oral cavity. In cell-free systems, PE generated hydrogen
Research question: Proinflammatory advanced glycation end products (AGE), highly elevated within the uterine cavity of obese women, compromise endometrial function. Do AGE also impact preimplantation embryo development and
The cytotoxicities of the nitric oxide (NO) donors, S-nitroso-N-acetylpencillamine (SNAP) and three glyco-SNAPs, glucose-1-SNAP, glucose-2-SNAP, and fructose-1-SNAP, towards the human gingival epithelioid S-G cell line and three human carcinoma cell lines derived from tissues of the oral cavity were
BACKGROUND
The cytotoxicity of resin-based sealer is influential on the inflammatory reaction and cell survival for oral periapical cells. In this study, pachymic acid as an antioxidant was investigated for the improvement of bone disturbance against AH Plus (Dentsply DeTrey GmbH, Konstanz,
Photodynamic therapy (PDT) is a method for treating pre-cancerous and cancerous lesions of the skin, bladder and oral cavity. However, tumour recurrence after PDT remains problematic despite good initial response. Some studies have shown that PDT induces vascular endothelial growth factor (VEGF)
OBJECTIVE
This study was conducted to assess clinically whether intervention with instruction applying respiratory rehabilitation method for expectorating sputum was useful or not to obtain more suitable sputum for smear examination of acid-fast bacilli.
METHODS
All specimens examined were sputa
Diesel exhaust particles (DEP) are known to induce adverse biological responses such as inflammation of the airway. However, the relationship between the chemical characteristics of organic compounds adsorbed on DEP and their biological effects is not yet fully understood. In this study, the
Phagocytosis of apoptotic cells is essential during development and tissue remodeling. Our previous study has shown that the P2X(7) receptor regulates phagocytosis of nonopsonized particles and bacteria. In this study, we demonstrate that P2X(7) also mediates phagocytosis of apoptotic lymphocytes
Comparative toxicity was determined for twenty potential chemopreventive agents in the Human Epithelial Cell Cytotoxicity (HECC) Assay using epithelial cell cultures from eight different tissues including: skin, kidney, breast, bronchus, cervix, prostate, oral cavity, and liver. The endpoints
Gossypol, a polyphenolic compound isolated from cottonseeds, has been reported to possess many pharmacological activities, but whether it can influence inflammasome activation remains unclear. In this study, we found that in mouse macrophages, gossypol induced cell death characterized by rapid
Oral squamous cell carcinoma (OSCC), an aggressive cancer originating in the oral cavity, is one of the leading causes of cancer deaths in males worldwide. This study investigated the antitumor activity and mechanisms of piperlongumine (PL), a natural compound isolated from Piper longum L., in human
