Identifying the motive force is central to explaining chromosome motions during mitosis. Presently, there is no consensus on what it is. The author has proposed a minimal assumptions model for the dynamics of post-attachment chromosome motions based on nanoscale electrostatics. Given the electrical properties of tubulin and the dynamic instability of microtubules, it is possible to account for prometaphase post-attachment, metaphase, and anaphase chromosome motions within a comprehensive model. The model addresses all of the following in a unified manner: Efficiency of aster and spindle assembly and the motive force for the motion of asters and forming half-spindles. Chromatid pair attachment. Motion of monovalently attached chromatid pairs. Motion of bivalently attached chromatid pairs and chromosome congression. Metaphase chromatid pair oscillations. Chromatid separation and anaphase-A chromosome motion. Anaphase-B pole separation. An ab-initio calculation of the maximum tension force exerted by a microtubule during mitosis that falls within the experimental range. Poleward force generation of chromosomes at poles with associated microtubule flux.

White biotechnology, or industrial biotechnology as it is also known, refers to the use of living cells and/or their enzymes to create industrial products that are more easily degradable, require less energy, create less waste during production and sometimes perform better than products created using traditional chemical processes. Over the last decade considerable progress has been made in white biotechnology research, and further major scientific and technological breakthroughs are expected in the future. Fungi are ubiquitous in nature and have been sorted out from different habitats, including extreme environments (high temperature, low temperature, salinity and pH), and may be associated with plants (epiphytic, endophytic and rhizospheric). The fungal strains are beneficial as well as harmful for human beings. The beneficial fungal strains may play important roles in the agricultural, industrial, and medical sectors. The fungal strains and their products (enzymes, bioactive compounds, and secondary metabolites) are very useful for industry (e.g., the discovery of penicillin from Penicillium chrysogenum). This discovery was a milestone in the development of white biotechnology as the industrial production of penicillin and antibiotics using fungi moved industrial biotechnology into the modern era, transforming it into a global industrial technology. Since then, white biotechnology has steadily developed and now plays a key role in several industrial sectors, providing both high value nutraceutical and pharmaceutical products. The fungal strains and bioactive compounds also play an important role in environmental cleaning. This volume covers the latest developments and research in white biotechnology with a focus on diversity and enzymes.

This book summarizes early pioneering achievements in the field of human neural stem cell (hNSC) research and combines them with the latest advances in stem cell technology, including reprogramming and gene editing. The powerful potential of hNSC to generate and repair the developing and adult CNS has been confirmed by numerous experimental in vitro and in vivo studies. The book presents methods for hNSC derivation and discusses the mechanisms underlying NSC in vitro fate decisions and their in vivo therapeutic mode of action. The long-standing dogma that the human central nervous system (CNS) lacks the ability to regenerate was refuted at the end of the 20th century, when evidence of the presence of neurogenic zones in the adult human brain was found. These neurogenic zones are home to human neural stem cells (hNSCs), which are capable of self-renewing and differentiating into neurons, astrocytes and oligodendrocytes. NSCs isolated from human CNS have a number of clinical advantages, especially the innate potential to differentiate into functional neural cells. Nevertheless, their full clinical exploitation has been hindered by limited access to the tissue and low expansion potential. The search for an alternative to CNS sources of autologous, therapeutically competent hNSCs was the driving force for the many studies proving the in vitro plasticity of different somatic stem cells to generate NSCs and their functional progeny. Now the era of induced pluripotent stem cells has opened entirely new opportunities to achieve research and therapeutic goals with the aid of hNSCs.
This book addresses various aspects of the current castor bean research, including genetics, biotechnology, comparative genomics, and more specific topics such as oil metabolism and the ricin toxin. It also presents the whole genome sequencing of the castor bean and its impact on the mining of gene families and future plant breeding. Castor bean (Ricinus communis), an oilseed plant, belongs to the Euphorbiaceae (spurge) family. It is a tropical and subtropical crop valued for the high quality and uniform nature of its oil, which is mostly composed of the uncommon fatty acid ricinoleate. Castor bean oil has important industrial applications for the production of lubricants, cosmetics, medicines, and specialty chemicals, and castor bean has also been proposed as a biodiesel crop that does not pose concerns regarding the "food versus fuel" debate. However, it accumulates the type 2 ribosome-inactivating protein ricin in its seeds, and health concerns posed by ricin's high toxicity have prevented broader cultivation. Recently, there has been renewed interest in castor bean due to potential biosecurity issues.
