Nanopharmacology

This research maps the knowledge translation process for two different types of nanotechnologies applied to cancer: liposomes and metallic nanostructures (MNs). We performed a structural analysis of citation networks and text mining supported in controlled vocabularies. In the case of liposomes, our results identify subnetworks (invisible colleges) associated with different therapeutic strategies: nanopharmacology, hyperthermia, and gene therapy. Only in the pharmacological strategy was an organized knowledge translation process identified, which, however, is monopolized by the liposomal doxorubicins...

Nanopharmacology is a relatively newer branch of pharmacology which investigates interaction of a nanomedicine with living systems at the nanoscale level. Modern medicine is increasingly concerned with various surface modified nanocarriers, such as dendrimers, nanoparticles, carbon based nanomaterials, polymer-drug nanoconjugates, etc., which have immense therapeutic potential by target specific drug delivery, using nanoscaffolding and nanocontainers, owing to the specific physical, chemical and biological properties of these moieties that is related to their nanoscale size range...

Nanoparticles (NP) and nanoparticulated drug delivery promise to be the breakthrough for therapy in medicine but raise concerns in terms of nanotoxicity. We present quantitative murine biokinetics assays using polyelectrolyte-multilayer-coated gold NP (AuNP, core diameter 15 and 80 nm; (198)Au radio-labeled). Those were stably conjugated either with human serum albumin (alb-AuNP) or apolipoprotein E (apoE-AuNP), prior to intravenous injection. We compare the biokinetics of protein-AuNP-conjugates with citrate-stabilized AuNP (cit-AuNP)...

The paper is devoted to the new direction of science - carbonology. Carbon is the base of organic compounds. Compounds of carbon with metals are known. The article gives a brief description of the three allotropic forms of carbon (soot, graphite, diamond), and various types of hybridization in organic structures, describes the role of biogenic carbon. At the end of the twentieth century new carbon nanostructures were discovered: fullerenes and carbon nanotubes. Scientists all over the world study physical, chemical, pharmacological and toxicological properties of the allotropes of carbon structures, which are promising for nanochemistry, nanopharmacology and nanotoxicology...

Modern approaches to increasing the efficiency of liposomal transport of substances are discussed. Examples of creating new nanopharmacological drugs that exceed the pharmacokinetic characteristic of their classical analogs are given.

INTRODUCTION: Advanced cases of uterine carcinomas with parametrial and fornix infiltration often cause massive genital bleeding, with severe anemia, fast deterioration, and a high risk of death for patients; women with advanced uterine cancer (UC) and genital massive bleeding were treated using an endovascular therapy in local anesthesia. METHODS: Ten women with advanced UC and genital massive bleeding were hospitalized for a high risk of immediate death; after blood transfusions and resuscitation therapy, the patients were submitted to an experimental nanopharmacologic endovascular therapy in local anesthesia...

Nanotechnology is giving us a glimpse into a nascent field of nanopharmacology that deals with pharmacological phenomena at molecular scale. This review presents our perspective on the use of scanning probe microscopy techniques with special emphasis to multidimensional atomic force microscopy (m-AFM) to explore this new field with a particular emphasis to define targets, design therapeutics, and track outcomes of molecular-scale pharmacological interactions. The approach will be to first discuss operating principles of m-AFM and provide representative examples of studies to understand human health and disease at the molecular level and then to address different strategies in defining target macromolecules, screening potential drug candidates, developing and characterizing of drug delivery systems, and monitoring target-drug interactions...

In the general sense, nanomedicine is defined as the application of nanotechnologies including nanobiothechnologies in medicine. Under conditions of current rapid development of nanotechnologies, many terms and definitions lack clarity and precision and boundaries between traditional and nanotechnologies are equally poorly determined. Evidently, dimensional parameters alone are insufficient to refer someone or other work to the field of nanotechnology (e.g., nanomedicine). Fundamental novelty of nanomedicine as a branch of knowledge and technology is exemplified by the developments in pharmacology and design of medicinal products that brought about new nanomedical (nanopharmacological, nanopharmaceutical) drugs...

A new trend of scientific-technical and medical researches has been formed which unites nanoscience, nanotechnology, nanomedicine, nanopharmacology. Nanoparticles are the main product of nanotechnologies. Nanoparticles are organic and inorganic structures, their size being less than one hundred nanometers (nano from Greece nanos--a dwarf; particle is a separate unit which is separated from the whole). Prefix nano means 10(-9) m. Nanosizes are values from 1 to 100 nanometers, micro-sizes--from 100 to 1000 nanometers, and above 1000 nanometers--are macrosizes...

The literature data and own investigations of the use of the nanotechnologies in medicine have been analyzed in the article. First investigations in the field of nanotechnology made the basis of new decisions in medicine, pharmacology, gene engineering and robot technology. Miniaturisation defines new chemical, physical and biological characteristics of biological objects, which differ from macroobject's characteristics. Study of this unique properties allows developing new technologies and methods in medicine...

Based on Nanotechnology methods, Nanomedicine and Nanotecnology will obtain significant advances in areas such as Diagnostic, Regenerative Medicine and pharmacological Therapeutics. With nanotechnology-based drug delivery systems,important improvement on pharmacokinetics of drugs will take place, due to increased solubility, protection against decrease in drug effects due to excessive metabolism and subsequent increase of bioavailability. Improvement on pharmacodynamic parameters will occur also due to increased drug concentration in target tissues...

Ever increasing use of engineered carbon nanoparticles in nanopharmacology for selective imaging, sensor or drug delivery systems has increased the potential for blood platelet-nanoparticle interactions. We studied the effects of engineered and combustion-derived carbon nanoparticles on human platelet aggregation in vitro and rat vascular thrombosis in vivo. Multiplewall (MWNT), singlewall (SWNT) nanotubes, C60 fullerenes (C60CS) and mixed carbon nanoparticles (MCN) (0.2-300 microg ml(-1)) were investigated...

CONTEXT: Homeopathic medicine developed significant popularity in the nineteenth century in the United States and Europe as a result of its successes treating the infectious disease epidemics during that era. Homeopathic medicine is a medical system that is specifically oriented to using nanopharmacologic and ultramolecular doses of medicines to strengthen a person's immune and defense system rather than directly attacking the microbial agents. OBJECTIVES: To review the literature referenced in MEDLINE and in nonindexed homeopathic journals for placebo-controlled clinical trials using homeopathic medicines to treat people with AIDS or who are human immunodeficiency virus (HIV)-positive and to consider a different theoretical and methodological approach to treating people with the viral infection...
