Drug delivery carriers can maintain effective therapeutic concentrations in the eye. To this end, we developed lipid nanoparticles (L/NPs) in which the surface was modified with positively charged chitosan, which engaged in hydrogen bonding with the phospholipid membrane. We evaluated in vitro corneal permeability and release characteristics, ocular irritation, and drug dynamics of modified and...

Inflammation is one of the major toxic effects reported in the literature following nanoparticle (NP) exposure. Knowing the importance of neutrophils to orchestrate inflammation, it is surprising that the direct role of NPs on neutrophil biology is poorly documented. Here, we investigated if ZnO NPs can alter neutrophil biology. We found that ZnO NPs increased the cell size, induced cell shape ...

In the present article, we describe a study of antitumor activity in breast cell lines using silver nanoparticles (Ag NPs) synthesized by a microbiological method. These Ag NPs were tested for their antitumor activity against MCF7 and T47D cancer cells and MCF10-A normal breast cell line. We analyzed cell viability, apoptosis induction, and endocytosis activity of those cell lines and we observ...

Inorganic nanoparticles (NPs) appear as the forefront functional structure in nanotechnology. The preparation of functional materials based on inorganic NPs requires their assembly onto well-defined structures. Within this context, self-assembly at air-liquid interfaces is probably the best candidate for a universal procedure for active materials composed of assembled NPs. The detailed in situ ...

BACKGROUND Today, the commonly used antibiotics may more and more frequently be ineffective against multiple pathogens, due to the selection of resistant microbial strains. As a result, an effort to find a new approach for solving this issue has been considered. AIM The aim of this study is to investigate antimicrobial properties of allicin, silver nanoparticles (Ag NPs) and their combination...

Objective(s): Semiconductor zinc oxide nanoparticles (ZnO NPs) have unique properties, such as inherent selectivity and photosensitization effects under ultraviolet (UV) radiation. ZnO NPs serve as promising anticancer agents. However, UV radiation limits their penetration into the body. In most clinical settings, it is essential to use high-energy photons in the treatment of deep-seated tumors...

This experimental study investigates the possible protective effects of Gum Arabic (GA) and its nanoparticles in hepato- reno-toxicity induced by bromobenzene (BB) rats mechanisms action. Thirty-five adult male albino were sorted into following: Group 1 (control), 2 (NPs), 3 (GA, received ml/kg 10%w/v aqueous suspension), 4 (Gum-NPs, GA loaded NPs), 5 (BB), 460 mg/kg, 6 (GA+BB) 7 (GA-NPs+BB). T...

PURPOSE The interaction of Porphyromonas gingivalis with commensal streptococci promotes P. gingivalis colonization of the oral cavity. We previously showed that a synthetic peptide (BAR) derived from Streptococcus gordonii potently inhibited the formation of P. gingivalis/S. gordonii biofilms (IC50 =1.3 µM) and reduced P. gingivalis virulence in a mouse model of periodontitis. Thus, BAR repres...

Glioma has one of the highest mortality rates among primary brain tumors. The clinical treatment for glioma is very difficult due to its infiltration and specific growth locations. To achieve improved drug delivery to a brain tumor, we report the preparation and in vitro and in vivo evaluation of curcumin nanoparticles (Cur-NPs). The cyclic hexapeptide c(RGDf(N-me) VK)-C (cHP) has increased aff...

Neuropsychiatric symptoms (NPS) in Alzheimer's disease (AD) are widespread and disabling. This has been known since Dr. Alois Alzheimer's first case, Frau Auguste D., presented with emotional distress and delusions of infidelity/excessive jealousy, followed by cognitive symptoms. Being cognizant of this, in 2010 the Alzheimer's Association convened a research roundtable on the topic of NPS in A...
