BACKGROUND The results showed that the deciding factor is the culture medium in which the bacteria and the graphene oxide (GO) are incubated at the initial manipulation step. These findings allow better use of GO and GO-based materials more and be able to clearly apply them in the field of biomedical nanotechnology. RESULTS To study the use of GO sheets applied in the field of biomedical nano...

Hydrosols are hydrodistillation products of aromatic plants. They contain less than 1g/L of dispersed essential oils giving organoleptic properties. Hydrosols are subjected to microbial proliferation. Reasons for spoilage have to be found in the nature of substrates supporting growth and of microbiological contaminants. The composition in essential oils and the microbiota of 22 hydrosol samples...

objectives : platelet preparations are commonly used to enhance bone and soft tissue regeneration. considering the existing controversies on the efficacy of platelet products for tissue regeneration, more in vitro studies are required. the aim of the present study was to compare the in vitro effects of plasma rich in growth factors (prgf) and platelet-rich fibrin (prf) on proliferation and viab...

atherosclerosis is a chronic inflammatory disease of the arterial wall characterized by innate and adaptive immune responses to a variety of microbial and self-antigens. given the crucial role of adaptive immunity in the pathogenesis of atherosclerosis, this study was performed to investigate the proliferative response of peripheral blood mononuclear cells (pbmc) and interleukin (il)-2 producti...

The Human Microbiome Project is using next-generation sequencing and metagenomics to characterize microbial communities that inhabit our gastrointestinal tract and other body sites [1, 2]. Based on these efforts, it is becoming increasingly clear that commensal microbiota play a significant role in shaping human health and disease. Yet it will be necessary to identify important microbial metabo...

In light of recent suggestions concerning the relaxation of controls on phosphorus loading in Lake Erie, and in consideration of our current lack of baseline information on microbial communities in this system, a two-part analysis of the microbial ecology of the lake has been conducted. A comprehensive survey of the surface waters collected data on phytoplankton abundance, bacterial productivit...

Among the synthetic polymers, poly (3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) microbial polyester is one of the biocompatible and biodegradable copolymers in the nanomedicine scope. PHBV has key points and suitable properties to support cellular adhesion, proliferation and differentiation of nanofibers. Nanofibers are noticeably employed in order to enhance the performance of biomaterials,...

Studies of metagenomics and the human microbiome will tremendously expand our knowledge of the composition of microbial communities in the human body. As our understanding of microbial variation and corresponding genetic parameters is refined, this information can be applied to rational remodeling or "tailoring" of human-associated microbial communities and their associated functions. Physiolog...
