H2Oh! Water is actually two liquids disguised as one.

H2Oh!

Earth's most precious liquid is weird, and if it wasn't we would die. Now experiments have uncovered its secret: it's not one liquid, it's two

“WATER is very strange,” says Anders Nilsson. He should know: he has been studying the stuff for most of his working life. His claim may be hard for the rest of us to swallow – after all, what could be more ordinary than water? Its behaviour is so familiar, its appearance so commonplace, that we are tricked into assuming that it is more or less the same as everything else. But water is uniquely weird. If it weren’t, none of us would be here to notice.

For example, if water weren’t densest at around 4°C rather than as ice, lakes and rivers would freeze from the bottom up, slowly killing their inhabitants. If it weren’t so spectacularly good at absorbing heat, the planet would have boiled over long ago. And if its molecules, barrelling through membranes or darting down veins, weren’t so good at sweeping other chemicals along, plants and animals would die of malnutrition.

Scientists have been plumbing the depths of water’s strangeness since at least the time of Galileo, to no avail. But now, thanks to the work of Nilsson and others, we might be on the verge of understanding why it behaves the way it does. Their explanation is as strange and wonderful as the stuff itself: water isn’t one liquid, but two.

On one level, it’s no surprise that water comes in multiple forms. It exists in three phases, as a solid, liquid or gas, depending on the temperature and pressure where you find it. At sea level, water turns to steam at 100°C, but at altitude, where the atmospheric pressure is reduced, you can get …

Cutaneous Leishmaniasis: Immune Responses in Protection and Pathogenesis.

Immunology

Cutaneous leishmaniasis is a major public health problem and causes a range of diseases from self-healing infections to chronic disfiguring disease. Currently, there is no vaccine for leishmaniasis, and drug therapy is often ineffective. Since the discovery of CD4+ T helper 1 (TH1) cells and TH2 cells 30 years ago, studies of cutaneous leishmaniasis in mice have answered basic immunological questions concerning the development and maintenance of CD4+ T cell subsets. However, new strategies for controlling the human disease have not been forthcoming. Nevertheless, advances in our knowledge of the cells that participate in protection against Leishmania infection and the cells that mediate increased pathology have highlighted new approaches for vaccine development and immunotherapy. In this Review, we discuss the early events associated with infection, the CD4+ T cells that mediate protective immunity and the pathological role that CD8+ T cells can have in cutaneous leishmaniasis.

Cutaneous leishmaniasis — which is caused by several protozoal parasites of the genus Leishmania — is endemic to South and Central America, Northern Africa, the Middle East and parts of Asia, and an estimated 1 million new cases arise each year. Of particular interest to immunologists is the wide range of clinical manifestations associated with this disease, which, similar to tuberculosis and leprosy, is dictated largely by the type and magnitude of the immune response of the host. As in most infections, the immune response to cutaneous leishmaniasis depends on many host factors, as well as on the differences between the infecting Leishmania spp. Experimental infections in mice also exhibit a spectrum of clinical presentations depending on the mouse strain and the infecting parasite species or strain used.

• Cutaneous leishmaniasis exhibits a wide spectrum of clinical presentations that is determined largely by the host immune response. The host immune response to infection is influenced both by host genetics and the Leishmania spp. and/or strain.
• The rapid recruitment of neutrophils and inflammatory monocytes following infection with Leishmania influences the course of disease. Neutrophils can have both protective and deleterious roles, whereas inflammatory monocytes kill Leishmania parasites and differentiate into monocyte-derived dendritic cells that promote the development of protective CD4+ T helper 1 (TH1) cells.
• Control of Leishmania infection depends on the production of interferon-γ by CD4+ TH1 cells, which leads to enhanced killing by macrophages due to the production of reactive oxygen species and nitric oxide.
• CD8+ T cells recruited to Leishmania lesions exhibit a cytolytic profile and lyse infected cells without killing the parasites, which leads to enhanced inflammation and increased severity of disease. Controlling these pathogenic CD8+ T cells, or the downstream mediators of inflammation that they induce, is a new approach to leishmaniasis immunotherapy.
• Infection with Leishmania generates several types of CD4+ T cells that mediate resistance to reinfection, including effector T cells, effector memory T cells, central memory T cells and tissue-resident memory T cells. There is currently no Leishmania vaccine, and a hurdle for vaccine development is that the most effective T cells are short-lived effector T cells; targeting longer lived central memory and tissue-resident memory T cells is an alternative approach.

Roitt's Essential Immunology - the textbook of choice for students and instructors of immunology worldwide

Roitt’s Essential Immunology clearly explains the key principles needed by medical and health sciences students, from the basis of immunity to clinical applications.  A brand new introduction sets the scene to section 1, Fundamentals of Immunology, introducing the microbial world and the strategies the body employs to defend itself. Each chapter then guides the reader through a different part of the immune system, and explains the role of each cell or molecule individually, and then as a whole.  Section 2, Applied Immunology, discusses what happens when things go wrong, and the role the immune system plays alongside the damaging effects of a disease, including cancer, immunodeficiency, allergies and transplantation and the beneficial effects of vaccines......

Practical Textbook of Biochemistry for Medical Students 2nd Edition ebook

This book is in resonance with the Textbook of Biochemistry for Medical Students, by Vasudevan et al, which is now in the 7th edition. That textbook is now accepted not only inside India, but also various other countries in the world. The Spanish edition of the Textbook is already in market and a Russian edition is in preparation. Students are advised to clear the doubts by going through that main textbook. This practical book is prepared after consulting the syllabi of MBBS course of various universities. The contents are divided into qualitative and quantitative experiments, which the students are supposed to do by themselves in the practical classes. Further, a few more experiments are given, which may not be possible for the student to do by himself/herself. Some of these will be demonstrated in the practical classes. In the end, a few case reports are also included, which will be useful for the students to prepare the practical examinations.

The Theory of Disappearing Microbiota and the Epidemics of Chronic Diseases.

In the present era, medical scientists have been confounded by the increasing incidence of multiple diseases across the world, beginning first in developed countries, and gradually spreading to other areas as they develop. These include the rises in cases of obesity, asthma, hay fever, food allergies, inflammatory bowel disease, juvenile (type 1) diabetes and autism, among many others. Are these diseases, which affect different body systems, unrelated or can a unified theory explain the increased incidence of all of these?

I believe that the latter possibility is true, and that the central theory to explain why these diseases have arisen and by what mechanism is based on modern changes in early life events that are related to the human microbiome. According to this theory, the microbiome of humans and of other animals is not accidental, but has been selected over long time periods to optimize host reproductive success through interactions between the microbiota and host physiology. Early life is the crucial period during which the adult microbiome becomes established, and development of the host and of the microbiota occur together in a conjoined manner through a dynamic equilibrium that follows a well-choreographed path. In early life, the context is set for the important developmental decisions that are required for the immune system to distinguish between what is self and what is not self, for metabolic organs to partition how much energy to expend or to save, and for the brain to determine how to respond socially to a person who might be either a friend or a foe.
