Diversity and plasticity are hallmarks of mononuclear phagocytes, which are reflected in plaque formation and evolution. Different monocyte subsets, which differentially contribute to plaque infiltration and to atherosclerosis complications, have been identified. Similarly, depending on different environmental signals plaque-associated macrophages can express polarized pro- and antiatherogenic ...

Plaque formation can be controlled either chemically or mechanically. Chemical plaque removal suffers lots of disadvantages like chemical agent can't penetrate the biofilm or the amount of agent which has penetrated is very less to kill bacteria present and also long term use of chemical plaque control agents can lead to staining of teeth. So, mechanical removal of supragingival plaque remains ...

The current study describes the histopathology of angiographic chronic total occlusions including residual lumen patency, intimal plaque composition, patterns of neovascular channel formation, intimal plaque calcification, and cellular inflammation, analyzed according to occlusion duration and intimal plaque type (fibrocalcific vs. lipid laden vs. mixed). Histologic findings are related to prev...

Radioautographic evidence using CaCl2 is presented to demonstrate that the aorta has an inherent ability to bind calcium ion regardless of age, sex or species. The binding occurs primarily in the intima and is not homogeneously distributed. Experiments with boiled aorta suggest that the primary substance responsible is collagen. The binding of calcium by the aorta has a marked effect upon the s...

A mathematical analysis of the formation of hemolytic plaques in agar is presented. The results can be used to calculate the rate constant for antigen-antibody association and the distribution of antibody secretion rates. The limitations of the treatment and estimates of the expected errors involved are briefly discussed.

Mussel (Mytilus californianus) adhesion to marine surfaces involves an intricate and adaptive synergy of molecules and spatio-temporal processes. Although the molecules, such as mussel foot proteins (mfps), are well characterized, deposition details remain vague and speculative. Developing methods for the precise surveillance of conditions that apply during mfp deposition would aid both in unde...

In Alzheimer's disease (AD), hallmark β-amyloid deposits are characterized by the presence of activated microglia around them. Despite an extensive characterization of the relation of amyloid plaques with microglia, little is known about the initiation of this interaction. In this study, the detailed investigation of very small plaques in brain slices in AD transgenic mice of the line APP-PS1(d...

A total of one hundred twenty-one (121) adult male and female subjects completed a 6-month, double-blind clinical study comparing the effect on supragingival plaque formation and gingivitis of a dentifrice containing 0.3% Triclosan and 2.0% of a copolymer of methoxyethylene and maleic acid to a placebo dentifrice. Both the Triclosan/copolymer and placebo dentifrices contained 0.243% sodium fluo...

Hydroponic experiments were conducted to investigate the effect of radial oxygen loss (ROL) and external aeration on iron (Fe) plaque formation, and arsenic (As) accumulation and speciation in rice (Oryza sativa L.). The data showed that there were significant correlations between ROL and Fe concentrations in Fe plaque produced on different genotypes of rice. There were also significant differe...

PURPOSE Several antiplaque agents are being available in the market in spite of vast development of modern medical science, satisfactory treatment of 'oral diseases' by newer drugs is not fully achieved, rather the chemical compounds has exposed the patients to it is different ill effects, therefore, there is interest to find out effective remedy of any disease by harmless herbal drugs thus the...
