The natural hormones

This book develops the mathematical tools essential for students in the life sciences to describe interacting systems and predict their behavior. From predator-prey populations in an ecosystem, to hormone regulation within the body, the natural world abounds in dynamical systems that affect us profoundly.

Ebook "Plant hormones: Biosynthesis, signal transduction, action! (Revised third edition)" is a description of these natural chemicals: how they are synthesized and metabolized, how they act at both the organismal and molecular levels, how we measure them, a description of some of the roles they play in regulating plant growth and development, and the prospects for the genetic engineering of hormone levels or responses in crop plants.

Ebook "Advanced technologies for managing insect pests" among the highlights of this book is the use of novel insecticides acting on a specific site in an insect group and are compatible with natural enemies and the environment. One of such approaches is based on disrupting the activity of biochemical sites acting on transcription factors such as the Helix-Loop-Helix (bHLH) family, anti juvenile hormone (AJH) agents that target JH biosynthetic enzymes, G-protein coupled receptors (GPCR) and bursicon as a target for insect control.

Tregs are able of suppressing tumor-specific efector cells, such as lymphocytes CD8+, CD4+ and Natural Killer cells. Different drugs, especially different schedules of administration, like metronomic chemotherapy (mCHT), seem to be able to increase anticancer immunity, by acting on downregulation of Tregs.

Numerous studies of lingzhi, mainly in Vietnam, China, Korea, Japan and United States, have shown its effectiveness in treatment of a very wide range of diseases and symptoms. Lingzhi is the only known source of a group of triterpenes (those similar to steroid hormones), polysaccharides, cumarin, alkaloids... But the study on chemical constituents of lingzhi still has a shortage. In this paper we reported our last investigation on the chemical composition of Ganoderma lucidum, cultivated in Hanoi city.

Endocrine Disruptors (ED) are substances that impede the normal performance of the endocrine system. It leads to several adverse effects on health such as abnormalities of the reproductive, skeletal, immune, metabolic, neurological, cardiovascular system as well as several types of carcinomas. These could be either naturally occurring organic substances such as phytoestrogens or artificially synthesised chemicals employed in the manufacture of plastics, plasticizers, pesticides, synthetic hormones, pharma compounds etc.

Tamoxifen is used in hormone therapy for estrogen-receptor (ER)-positive breast cancer, but also has chemopreventative effects against ER-negative breast cancers. This study sought to investigate whether oral iron-saturated bovine lactoferrin (Fe-Lf), a natural product which enhances chemotherapy, could improve the chemotherapeutic effects of tamoxifen in the treatment of ER-negative breast cancers.
