Download The Poison Paradox: Chemicals As Friends and Foes by John Timbrell PDF

By John Timbrell

Each day we're surrounded via chemical substances which are in all likelihood destructive. a few of these we take deliberately within the type of medicinal drugs; a few we take unknowingly throughout the foodstuff we consume, and the surroundings round us. John Timbrell explores what makes specific chemical substances destructive, what their results are, and the way we will try out for them. He examines medicines akin to Paracetamol and what it does to the physique; Ricin, the main poisonous substance identified to guy; Paraquat, a greatly on hand weedkiller; and the way the puffer fish, eaten as a delicacy in Japan, can kill. utilizing case stories from all over the international, equivalent to the Spanish Oil syndrome which remodeled 20,000 humans sick in Madrid, Timbrell uncovers the proof at the back of chemical scares. He indicates how, with a rational, medical, and balanced method, hazards will be assessed and controlled competently.

Download BMP Receptor by Reddi A. PDF

By Reddi A.

Bone morphogenetic proteins (BMPs) are osteotro-phic and osteoinductive cytokines. BMPs are pleio-tropic cytokines with activities not just on bone and cartilage but additionally on mind, the teeth, epidermis, middle, lung, kidney, and a number of different tissues. They act on chemotaxis. mitosis, differentiation, mobile survival and telephone demise. The organic activities of BMPs are med-iated via binding to express BMP receptors varieties I and II. there's a collaboration among the receptors and downstream substrates corresponding to receptor-regulated R-Smads 1, five, and eight. The phosphorylated R-Smads companion with Co-Smad. Smad4. and input the nucleus to start up the transcription of BMP-responsive genes. Smad6 inhibits the job of kind I BMP receptor protein kinase. therefore, the BMP receptors supply a finely regulated homeostatic procedure with assessments and balances.

Recent Advances in Polyphenol Research

Volume 2

Edited by means of Santos-Buelga, Escribano-Bailon and Lattanzio

Plant phenolics are secondary metabolites that represent the most universal and frequent teams of drugs in vegetation. Polyphenols have a wide and numerous array of necessary results on either crops and animals. for instance they're recognized as antioxidants, hormones, components of crucial oils and average neurotransmitters.

Sponsored through Groupe Polyphenols, this booklet, that's the second one quantity during this ground-breaking sequence, is edited by means of Celestino Santos-Buelga, Maria Teresa Escribano-Bailon, and Vincenzo Lattanzio, who've drawn jointly a powerful checklist of the world over revered authors, every one offering leading edge chapters overlaying many of the significant issues of modern learn and interest.

Information integrated during this very important new addition to the sequence comprise the next areas:

• Flavonoid chemistry of the leguminosae

• Chemistry and organic job of ellagitannins

• Chemistry and serve as of anthocyanins in plants

• An replace of chemical pathways resulting in new phenolic pigments in the course of wine ageing

• Metabolic engineering of the flavonoid pathway

• the interpretation of chemical homes of polyphenols into organic task with affects in human health

• Plant phenolic compounds controlling leaf movement

• organic task of phenolics in plants

Chemists, biochemists, plant scientists, pharmacognosists and pharmacologists, nutrition scientists and nutritionists will all locate this ebook a useful source. Libraries in all universities and study institutions the place those topics are studied and taught must have copies on their cabinets.

By Professor Francis Dov Por (auth.)

There are few achievements of contemporary guy that may examine to the Suez Canal. In Egypt-the land of the main well-known wonders of antiquity-the Suez Canal used to be equipped because the first technical ask yourself ofthe commercial revolution. Ferdinand de Lesseps used to be a guy straddling epochs-the romantic utopism of Saint­ Simon and the fashionable global of technocracy. the large undertaking used to be at its commence shouldered through the crowds of tens of millions of compelled workers nonetheless on hand and ended as a show-piece for contemporary mechanical earth-moving concepts. The canal developers themselves have been nonetheless polyhistors within the outdated feel: engineers­ cum-zoologists; naval officers-cum-geologists; diplomats meddling with chem­ istry. in the course of the 4 generations of the lifestyles of the Suez Canal, the fateful expert narrowmindedness turned steadily worse. The engineers con­ tinued their paintings in and round the Canal, yet they grew to become oblivious and unresponsive to the environmental effect, to the interesting alterations within the biotic surroundings which they have been generating with their very own hands.

Download Vorbild Natur: Bionik-Design für funktionelles Gestalten by Werner Nachtigall PDF

By Werner Nachtigall

Von der Natur für die Technik lernen: für unsere Zeit eine gebieterische Forderung. Denn technische Lösungen mit natürlichen Vorbildern helfen, fabric und Energie zu sparen und Umweltressourcen zu schonen. Werner Nachtigall zeigt, wie guy Grundkonzepte der Natur als Bionik-Design übernehmen und eigenständig weiterentwickeln kann. Vom Staunen über die "Wunder der Natur" führt er die Leser zum Verständnis der biologischen Prozesse und Konstruktionsprinzipien. Viele Beispiele geben eine Vorstellung davon, wie sich diese Prinzipien in die Welt der Technik übertragen lassen. Biologie und Technik treffen sich so zum Wohle der Menschen und der Umwelt. Prof. Dr. W. Nachtigall, geb. 1934, ist seit 1969 Ordinarius für Zoologie an der Universität Saarbrücken. Dort baute er neben seinem Spezialgebiet, der Bewegungsphysiologie, schon sehr früh den Kontakt zu den Nachbardisziplinen aus und gründete die Forschungs- und Ausbildungsrichtung "Technische Biologie und Bionik".
