It is a very practical tropics companion for the increasing number of medical students and junior doctors who have the opportunity to practice medicine in the tropics. The Integrates the basic science book integrates basic science with clinical practice, with disease-orientated with clinical practice descriptions and clinical presentations on a system-by-system basis. Core introductory text for the For this new sixth edition the text has been brought fully up to date throughout. The student and the practitioner highly structured and improved text is designed to facilitate easy access to information, making the book an ideal resource for clinical attachments and revision. Major update throughout and There is a new chapter that covers infections in special groups, as well as coverage new chapter on infections in of sepsis and septic shock.
The tendency today cheap aciphex 20 mg with mastercard gastritis back pain, not surprisingly, is to avoid having to keep any exotic types on the payroll if at all possible, and to play safe and secure the financing of a new title right from the start by selling part of an edition to a pharmaceutical company. Thirdly, and this is perhaps the saddest point for doctors: morals are becoming rougher, the rules of courtesy are sinking into oblivion. Flying Publisher generation ago, old people say, courtesy and reserve ruled over any contact between doctors and publishers. In the age of rapid production, the doctor is becoming a supplier of raw material, has to meet delivery deadlines more than ever and is treated the way many people tend to treat delivery men: rudely. But to come back to the point mentioned at the beginning, that publishers are an important supervisory factor for the quality of our texts. In principle, supervisory bodies make sense, but are publishers the right ones for the job? Who has the right to decide whether something written by someone who has been practising his profession for 20 or 30 years should be published? The short-term image boost is stronger if your book is published by an established publishing house. The arguments that go against an author having a contract with a traditional publisher are: as a rule, you have to cede the rights to your own text; it is seldom possible today to persuade publishers to present a free parallel publication of the text on the internet; producing your own book can be considerably more lucrative. Thus, the following speak in favour of publishing your medical textbook by yourself: 1. The better establishment of your textbook in the long-term, since the parallel publication of a text both as a book and an internet version is still rare today. This gives you a selective advantage over authors who continue to publish their texts as books only. We therefore advise all colleagues to produce and market their textbooks themselves. Print: the share that print costs have in the retail price depends on the size of circulation and the price. Distribution: the share of distribution costs amounts to approximately 45% of the retail price. This percentage is irrespective of the distribution channels (book wholesaler, sponsors). Profit: depending on circulation, profit is somewhere between 27 (100% - 45% - 28%) and more than 40% (100% - 45% - 13. The future reader (R) goes into a bookshop (B) and pays the retail price (yellow arrow). The bookseller or wholesaler pays the publishing house (X) after deducting a sales margin of 30 to 45%. The publisher has previously transferred payment for the printing costs to the print shop (P) and pays the authors off over several months or years. The publishers are out of the game and the authors market the books directly through the most important specialised medical bookshops. The future reader (R) goes into the bookstore (B), pays the retail price, and the bookseller remits 70% of this to the authors (A). The authors have previously transferred payment of the printing costs to the print shop (P). In this diagram, we have replaced the bookstore with a sponsor, such as a foundation (S). The sponsor pays the authors for the discounted books, and the authors in turn pay the printer (P). The reader (R) generally receives the books free of charge and is grateful (blue arrow). One or more sponsors have taken on a circulation of 1000 books and give the books away to doctors who are interested. Blue arrow: gratitude In chapters 2 and 4 we go on to develop the thoroughly fascinating subject of financing and we will see that it is by no means ruinous to manufacture and market books. We also investigate the sales figures needed to make book production financially interesting. You already know that profits from book production can be two to six times higher than an authorās royalties. Whoever starts running now might be first past the post, and whoever gets established first will have a head start which will make it hard for competitors to catch up. If you keep your copyright, you are your own master and can enjoy previously undreamed of liberties.
But once you have understood the basic word roots discount 10 mg aciphex overnight delivery gastritis symptoms burning, combining word forms, prefixes and suffix you will find that anatomical terminologies are not as difficult as you first imagined. Anatomical positions are universally accepted as the starting points for positional references to the body. In anatomical position the subject is standing erect and facing the observer, the feet are together, and the arms are hanging at the sides with the palms facing forward. Relative means the location of one part of the body is always described in relation to another part of the body. Body parts Regions The body can generally be described to have areas of: Axial body part: - It is the part of the body near the axis of the body. It is customary to subdivide the abdominal area into nine regions or more easily in to four quadrants. The two main body cavities are the larger ventral (anterior) and the smaller, dorsal (posterior) body cavity. It consists of the right and left pleural cavities and mediastinum (the portion of tissues and organs that separates the left and right lung). It is divided into superior abdominal and inferior pelvic cavity by imaginary line passing at upper pelvis. The anatomical term opposite to lateral is: - a) Proximal b) Distal c) Medial d) Superficial e) Caudal. This phenomenon is called: a) Anatomical integrity b) Physiological stablity c) Homeostasis d) Hemostasis e) Body stasis 3. A plane that divided the body into anterior and posterior parts is: - a) Medial plane b) Coronal or frontal plane c) Sagital plane d) Transverse plane e) Oblique plane 5. Cytology: - It is a branch of science concerned with a study of cells Cell Theory explains about a) All living organisms are composed of cell and cell products. To know more about cell, we can divide the cell in to four principal parts: - Plasma (cell) membrane: it is the outer lining, limiting membrane separating the cell internal parts from extra cellular materials & external environment. Cytoplasm: cytoplasm is the substance that surrounds organelles and is located between the nucleus and plasma membrane 17 Human Anatomy and Physiology Organelles: these are permanent structures with characteristic morphology that are highly specialized in specific cellular activity. Extra cellular materials are also referred to as the matrix, which are substances external to the cell surface. The quality selective permeability Movement across-cell membrane Movements a cross membrane takes place in two ways. Simple diffusion, the random movements of molecules from area of high concentration to the area of low concentration. Facilitated diffusion, larger molecules, which are not soluble in lipid need protein channel to pass through the plasma membrane. Osmosis, a special type of diffusion referring to the passage of water through a selectively permeable membrane from an area of high water concentration to lower water concentration. Filtration, small molecules pass through selectively permeable membrane in response to force of pressure. Active movements across membranes Substances move through a selectively permeable membrane from areas of low concentration on side of a membrane to an area of higher concentration on the other side. But if equilibrium reached and still more molecules are needed, they must be pumped 20 Human Anatomy and Physiology through the membrane against concentration gradient. It includes: Pinocytoss ā cell drinking Receptor ā mediated Endocytosis- Endocytosis with the help of receptor. It is thick semi transparent, elastic fluid containing suspended particles and a series of minute tubules and filaments that form cytoskeleton. The inorganic components exist as solutions 21 Human Anatomy and Physiology because they are soluble in water. In the nucleus a jelly like fluid that fill the nucleus is karylymph (neucleoplasm), which contain the genetic material called chromosome. They are site of protein synthesis 22 Human Anatomy and Physiology c) Endoplasmic reticulum is a double membrane channel. Various products are transported from one portion of the cell to another via the endoplasmic reticulum. Each mitochondria posses two membrane, one is smooth (upper) membrane and the other is arranged with series of folds called cristae.
