Nanoparticles in Humans - Experiments, Methods, and Strategies (Hardcover): Lev S. Ruzer Nanoparticles in Humans - Experiments, Methods, and Strategies (Hardcover)
Lev S. Ruzer
R2,097 Discovery Miles 20 970 Shipped within 7 - 12 working days

A review of the literature on the environmental health implications of the developing nanotechnology industry shows that the potential problem of exposure to airborne nanoparticles has not been adequately assessed. The health and safety of nanotechnology workers is of concern because these groups are likely to be exposed to elevated concentrations of nanomaterials. A gap exists between currently available particle measurement methods and those appropriate for nanoaerosol exposure assessment.
Nanoparticles in Humans: Experiments, Methods and Strategies presents new ideas, methods, and experimental results to measure the surface area and local deposition of nanoparticles in lungs and the true effectiveness of respirators. It includes a nanoparticles dosimetric road map that can be used as a general strategy for the assessment of dose, which is the most important physical cause of health effect in case of nanoparticles exposure.
This book proposes the 1 nm radioactive particle, called unattached activity of radon progeny, which can be used as a useful and safe experimental tool for nanoparticles study, including human study. Such ideas have not been presented in other publications before. It discusses problems related to the general strategy of risk assessment in nanoparticles exposure and concrete parameters related to dosage, which is the main cause of the health effects associated with nanoparticles.
The book uniquely uses graphs and diagrams to build an understanding of the methods for measuring the surface area and local deposition of nanoparticles in lungs and the effectiveness of respirators in case of nanoparticles exposure.

Plant endophytes are a potential source for the production of bioactive compounds that can fight against devastating diseases in both plants and humans. Among these endophytic microorganisms, endophytic fungi are one of the dominant group of microorganisms with a potential role in plant growth promotion and the discovery of noble bioactive natural products. Endophytic fungi possess several bioactivities like anticancer, antimicrobial, insecticidal, plant growth stimulants, crop protection, phytoremediation, etc. Presence of modular biosynthetic genes clusters like PKS and NRPS in several endophytic fungi underscores the need to understand and explore such organisms. This volume presents and demonstrates the applied aspects of endophytic fungi. Practical applications of such endophytes are discussed in detail, including studies in pharmaceutical development and agricultural management of important microbial diseases. The beneficial effects that endophytic fungi provide to host plants-enhancing growth, increasing fitness, strengthening tolerance to abiotic and biotic stresses through secondary metabolites-are also discussed. The reader is provided with a comprehensive and detailed understanding of such relationships between endophytic fungi and their host.

R984 R895 Discovery Miles 8 950 Save R89 (9%) Shipped within 7 - 12 working days

This thesis lays the groundwork for the automatic supervision of the laser incision process, which aims to complement surgeons' perception of the state of tissues and enhance their control over laser incisions. The research problem is formulated as the estimation of variables that are representative of the state of tissues during laser cutting. Prior research in this area leveraged numerical computation methods that bear a high computational cost and are not straightforward to use in a surgical setting. This book proposes a novel solution to this problem, using models inspired by the ability of experienced surgeons to perform precise and clean laser cutting. It shows that these new models, which were extracted from experimental data using statistical learning techniques, are straightforward to use in a surgical setup, allowing greater precision in laser-based surgical procedures.

This authored monograph supplies empirical evidence for the Bayesian brain hypothesis by modeling event-related potentials (ERP) of the human electroencephalogram (EEG) during successive trials in cognitive tasks. The employed observer models are useful to compute probability distributions over observable events and hidden states, depending on which are present in the respective tasks. Bayesian model selection is then used to choose the model which best explains the ERP amplitude fluctuations. Thus, this book constitutes a decisive step towards a better understanding of the neural coding and computing of probabilities following Bayesian rules. The target audience primarily comprises research experts in the field of computational neurosciences, but the book may also be beneficial for graduate students who want to specialize in this field.

R2,463 Discovery Miles 24 630 Shipped within 7 - 12 working days

In the area of controlled release of active substances, such as drugs, a strong interest in nanoparticles as carriers of active ingredients has arisen. Some of the active components are extremely hydrophobic, without cellular permeability and susceptible to metabolic degradation. Owing to this, their use is limited. This kind of agent can be transported without any problem through physiological media by using nanoparticles. The size of particles is an important parameter because it governs the efficiency of the delivery system. For this type of application, particles that have a diameter smaller than 1 m are especially useful. Polymeric nanoparticles that have diameters in the colloidal range are produced by means of polymerization processes in dispersed media. Drugs are taken up into the nanoparticles by adsorption, absorption, or "entrapment," or covalent bonding and they are delivered (release) by desorption, diffusion, polymer degradation, or a combination of these mechanisms. Nanoparticles (including nanogels) that release their contents by external triggering open up new possibilities for therapeutic strategies. External triggering by light, heat, change in pH, or application of ultrasound opens up the possibility to release the material on demand. If only a part of the wall of the nanoparticle (nanocapsule) is responsive, we are dealing with the so-called nanobottles, a nanocontainer with the active substance and a lid on the container that can be "opened" and "closed" by external triggering. This book focuses on responsive nanoparticles and brings together two interesting areas: nanoparticles and responsive polymers. The concept of the book is that of a systematic approach from nanoparticles synthesis via responsive polymers to nanobottles. The second part of the book presents contributions from experts in the field and provides a state-of-the-art overview of the field.

This work represents an inventive attempt to apply recent advances in nanotechnology to identify and characterise novel polymer systems for drug delivery through the skin. Atomic force microscopy (AFM) measurements of the nanoscale mechanical properties of topical, drug-containing polymeric films enabled the author to identify optimal compositions, in terms of flexibility and substantivity, for application to the skin. To elucidate the enhanced drug release from polyacrylate films incorporating medium chain triglycerides, the author combined AFM studies with the complementary technique of Raman micro-spectroscopy. This experimental strategy revealed that the significant increase in the drug released from these films is the result of a nanoscale two-phase structure. Finally, in experiments examining the microporation of skin using femtosecond laser ablation, the author demonstrated that the threshold at which the skin's barrier function is undermined can be dramatically reduced by the pre-application of ink. The approach allows thermal damage at the pore edge to be minimised, suggesting a very real potential for substantially increasing drug delivery in a minimally invasive fashion.
