OBJECTIVES To screen novel small molecule compounds for inhibition of Mycoplasma bovis growth and to characterize their activity in terms of dose-dependency and ability to function in milk. METHODS Using a tetrazolium salt cytotoxicity assay, 480 natural compounds were screened to determine which of the small molecules have the potential to become therapeutic options for M. bovis prevention a...

OBJECTIVE Green tea extract (GTE) was shown to be effective in preserving periodontal ligament fibroblasts (PDLFs) of avulsed teeth. This study aimed at determining the potential of GTE in preserving the viability of PDLFs comparing with different storage media. MATERIALS AND METHODS Periodontal ligament cells were obtained from freshly extracted healthy impacted third molars and cultured in ...

BACKGROUND In the pathophysiology of implant failure, metal ions and inflammation-driven osteoclasts (OC) play a crucial role. The aim of this study was to investigate whether vanadium (V) ions induce differentiation of monocytic OC precursors into osteoresorptive multinucleated cells. In addition, the influence of V ions on the activation and function of in vitro generated OC was observed. M...

Mesoporous silica nanoparticles (MSNs) have been synthesized and loaded with both aluminum chloride phthalocyanine (AlClPc) and cisplatin as combinatorial therapeutics for treating cancer. The structural and photophysical properties of the MSN materials were characterized by different spectroscopic and microscopic techniques. Intracellular uptake and cytotoxicity were evaluated in human cervica...

In recent years, algae have been highlighted as potential sources of anticancer agents. Laminarin is a molecule found in marine brown algae that has potentially beneficial biological activities. However, these activities have not been investigated. In the present study, we examined the effects of laminarin on HT-29 cells and analyzed its effect on...

Purpose: To evaluate the influence of triamcinolone acetonide on the proliferation of retinal pigment epithelum cells in an experimental cell culture study. Methods: Pooled fresh porcine retinal pigment epithelium cell cultures were exposed to triamcinolone acetonide in increasing concentrations after the solvent agent had been removed. The proliferation rate was measured using the (3-(4,5-dime...

DNA single strand breaks (SSBs) are one of the most frequent DNA lesions in genomic DNA generated either by oxidative stress or during the base excision repair pathways. Here we established a new real-time assay to assess an imbalance of DNA SSB repair by indirectly measuring PARP-1 activation through the depletion of intracellular NAD(P)H. A water-soluble tetrazolium salt is used to monitor th...

AIM The increased consumption of traditional medicinal plants has been driven by the notion that herbal products are safe and efficient. The purpose of this study was to evaluate the safety and the protective effect of a hydro alcoholic extract of Desmodium adscendens (DA) on liver (HEPG2) and kidney (LLC-PK1) cells. MATERIALS AND METHODS A hydro alcoholic extract of DA was used. HEPG2 or LLC...

Endocrine resistance is a major problem with anti-estrogen treatments and how to overcome resistance is a major concern in the clinic. Reliable measurement of cell viability, proliferation, growth inhibition and death is important in screening for drug treatment efficacy in vitro. This report describes and compares commonly used proliferation assays for induced estrogen-responsive MCF-7 breast ...
