Sensory transmission in the gastrointestinal tract

Image The gastrointestinal (GI) tract must balance ostensibly opposite functions. On the one hand, it must undertake the process of digestion and absorption of nutrients. At the same time, the GI tract must protect itself from potential harmful antigenic and pathogenic material. Central to these processes is the ability to sense the mechanical and chemical environment in the gut wall and lumen in order to orchestrate the appropriate response that facilitates nutrient assimilation or the rapid expulsion through diarrhoea and/or vomiting. In this respect, the GI tract is richly endowed with sensory elements that monitor  thegut environment. Enteric neurones provide one source of such sensory innervation and... Read More

Mutagen produces mutations in the DNA

Image In genetics, a mutagen is a physical or chemical agent that changes the genetic material, usually DNA, of an organism and thus increases the frequency of mutations above the natural background level. As many mutations can cause cancer, mutagens are therefore also likely to be carcinogens, although not always necessarily so. All mutagens have characteristic mutational signatures with some chemicals becoming mutagenic through cellular processes. Not all mutations are caused by mutagens: so-called "spontaneous mutations" occur due to spontaneous hydrolysis, errors in DNA replication, repair and recombination. Mutagens can cause changes to the DNA and are therefore genotoxic. They can... Read More

Image Multiple sclerosis (MS) is a demyelinating disease in which the insulating covers of nerve cells in the brain and spinal cord are damaged. While the cause is unclear, the underlying mechanism is thought to be either destruction by the immune system or failure of the myelin-producing cells. CAUSES: The cause of MS is unknown; however, it is believed to occur as a result of some combination of genetic and environmental factors such as infectious agents. Theories try to combine the data into likely explanations, but none has proved definitive. While there are a number of environmental risk factors and although some are partly modifiable, further research is needed to determine whether their elimination can... Read More

Range of motion for better result.

Image The motion range (or ROM) is the linear or angular distance that a moving body will usually move while properly connected to another body. It is also called travel range (or ROT), particularly when thinking about mechanical devices and in fields of mechanical engineering. As used in the biomedical field and by weightlifters, motion range refers to the distance and direction that a joint will travel between the flexed position and the extended position. The act of attempting to increase this distance through therapeutic exercises (range of motion therapy — stretching for physiological benefit from flexion to extension) is also... Read More

Poliosis circumscripta a genetic disorder.

Image : Poliosis is the decrease or absence of melanin (or color) in head hair, eyebrows, eyelashes, or any other hairy region. When it affects hair immediately above the forehead it is popularly known as white forelock. Single or less commonly, several white patches on the hair may cause this condition. Some mistake those white patches for simple marks of birth. In poliosis, the hair bulbs of infected hair follicles contain reduced or absent melanin; skin melanocytes are generally not infected. Poliosis occurs in various hereditary syndromes, including piebaldism, Waardenburg syndrome, type I neurofibromatosis, and tuberous sclerosis. It can also occur... Read More

Zwitterions in daily life

Image A zwitterion is a molecule containing an equal number of functional group(s) charged positively and of functional group(s) charged negatively. Zwitterions may also be called internal salts. With amino acids, for example, a chemical equilibrium between the "parent" molecule and the zwitterion will be formed in solution. Betaines are zwitterions that cannot isomerize to an all-neutral form, for instance when the positive charge is on a quaternary ammonium group. Likewise, a molecule that comprises a group of phosphoniums and a group of carboxylate cannot isomerise. Although the equilibrium cannot be experimentally studied in solution between a compound and its zwitterion... Read More

Integrating Yoga Into Cancer Care

Image Although yoga has been practiced in Eastern culture for thousands of years as part of life philosophy, classes in the United States only recently have been offered to people with cancer. The word yoga is derived from the Sanskrit root yuj, meaning to bind, join, and yoke. This reflection of the union of the body, mind, and spirit is what differentiates yoga from general exercise programs. Yoga classes in the United States generally consist of asanas (postures), which are designed to exercise every muscle, nerve, and gland in the body. The postures are combined with pranayama, or rhythmic control of... Read More

Folate, Methionine, and Alcohol Intake and Risk of Colorectal Adenoma

Image  Reduced methylation of DNA may contribute to loss of the normal controls on proto-oncogene expression. In humans, hypomethylation of DNA has been observed in colorectal cancers and in their adenomatous polyp precursors. Accumulation of DNA methylation abnormalities, observed during progression of human colorectal neoplasia, may be influenced by certain dietary factors. The apparent protective effect of fresh fruits and vegetables, the major folate sources, on colorectal cancer incidence suggests that a methyldeficient diet contributes to occurrence of this malignancy. Low dietary folate and methionine and high intake of alcohol may reduce levels of S-adenosylmethionlne, which is required for DNA methylation.... Read More

Evaluating Hallucinogenic or Psychedelic Drug Intoxication in an Emergency Setting

Image Under certain conditions or in an overdose setting, several classes of drugs can induce illusions, hallucinations, or delusions. However, one of the hallmark features of hallucinogens or psychedelic agents is their ability to induce states of altered or distorted perception, thought, and mood. Many hallucinogens produce classic sympathomimetic effects; that is, hyperactivity, mydriasis (dilated pupils), hypertension, tachycardia, and hyperthermia. However, the effects vary considerably, depending upon the hallucinogen ingested. Qualitative confirmation by the laboratory that the patient is suffering from hallucinogen intoxication such as marijuana use can be helpful to the clinician. However, the common toxicologic drug screens used by... Read More

Impacts of Drugs on Neurotransmission

Image Drugs of abuse alter the way people think, feel, and behave by disrupting neurotransmission, the process of communication between brain cells. Over the past few decades, studies have established that drug dependence and addiction are features of an organic brain disease caused by drugs' cumulative impacts on neurotransmission. Scientists continue to build on this essential understanding with experiments to further elucidate the physiological bases for drug abuse vulnerability as well as the full dimensions and progression of the disease. The findings provide powerful leads to new medications and behavioral treatments. A person reads. The words on the page enter the... Read More

As a part of the vertebrate innate immune system monocytes also influence the process of adaptive immunity. There are at least three subclasses of monocytes in human blood based on their phenotypic receptors. Monocytes are amoeboid in appearance, and have nongranulated cytoplasm.[1], thus are classified as agranulocytes. Containing unilobar nuclei, these cells are one of the types of mononuclear leukocytes which shelter azurophil granules. The archetypal geometry of the monocyte nucleus is ellipsoidal;... Read More

Kupffer –Browicz cells, are specialized macrophages

Image Kupffer cells, also known as stellate macrophages and Kupffer–Browicz cells, are specialized macrophages located in the liver, lining the walls of the sinusoids. They form part of the mononuclear phagocyte system Development. Their development begins in the yolk sac where they differentiate into fetal macrophages. Once they enter the blood stream, they migrate to the fetal liver where they stay. There they complete their differentiation into Kupffer cells.Function apart from clearing any bacteria, red blood cells are also broken down by phagocytic action, where the hemoglobin molecule is split. The globin chains are re-used, while the iron-containing portion, heme, is... Read More

Immunopharmacology

Image The immune system is a composite of the means by which individual organisms maintain their individual integrity in the face of constant interaction with the environment and the continuous internal process of death and removal of host cells that allows for replacement and growth. Both the innate and adaptive divisions of the immune system are critical to the maintenance of homeostasis, physical integrity, and health. Intricately interactive pathways of cells, cell surface receptors, antibodies, and cytokines provide surveillance against invasive pathogens and nonself entities and internal destruction and removal of host senescent cells. The specificity and efficacy of these immune... Read More

Immunology of Barrier Surfaces

Image Barrier surfaces are the first to come into contact with pathogens and have overlapping and unique immunological mechanisms to prevent infection. The lung, gut and skin form major physcial and immunological barriers to infection. These organs are the main portal of entry for a variety of air and food borne pathogens, allergens and other environmental pollutants.  They have the unique ability to maintain homeostasis in the face of constant external provocation.  Once this property is jeopardized, different types of diseases ensue.  Although the underlying mechanisms of some of these diseases are not known, it is now becoming clear that immune...

Immune system's ability to fight infectious disease and cancer

Image Immunodeficiency or immunocompromise is a state in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. Most cases of immunodeficiency are acquired ("secondary") due to extrinsic factors that affect the patient's immune system. Examples of these extrinsic factors include HIV infection and environmental factors, such as nutrition. In the clinical setting, the immunosuppression by some drugs, such as steroids, can be either an adverse effect or the intended purpose of the treatment. Examples of such use is in organ transplant surgery as an anti-rejection measure and in patients suffering from an overactive immune... Read More

HIV infects vital cells in the human immune system

Image The human immunodeficiency viruses (HIV) are two species of Lentivirus (a subgroup of retrovirus) that infect humans. Over time they cause acquired immunodeficiency syndrome (AIDS), a condition in which progressive failure of the immune system allows life-threatening opportunistic infections and cancers to thrive.Without treatment, average survival time after infection with HIV is estimated to be 9 to 11 years, depending on the HIV subtype.In most cases, HIV is a sexually transmitted infection and occurs by contact with or transfer of blood, pre-ejaculate, semen, and vaginal fluids.

Prostate-specific antigen test

Image Prostate-specific antigen (PSA), also known as gamma-seminoprotein or kallikrein-3 (KLK3), is a glycoprotein enzyme encoded in humans by the KLK3 gene. PSA is a member of the kallikrein-related peptidase family and is secreted by the epithelial cells of the prostate gland. PSA is produced for the ejaculate, where it liquefies semen in the seminal coagulum and allows sperm to swim freely. It is also believed to be instrumental in dissolving cervical mucus, allowing the entry of sperm into the uterus. PSA is present in small quantities in the serum of men with healthy prostates, but is often elevated in the presence of prostate cancer or other prostate disorders. PSA is not a unique indicator of prostate cancer, but may also detect prostatitis or benign prostatic hyperplasia.

Evaluation of HepaRG Cells as an in Vitro Model for Human Drug Metabolism Studies

Image HepaRG cells, a newly developed human hepatoma cell line, differentiate into hepatocyte-like morphology by treatment with dimethyl sulfoxide (DMSO). The expression of cytochrome P450 (P450) enzymes, transporter proteins, and transcription factors was stable in differentiated HepaRG cells over a period of 6 weeks when cultured with DMSO. Compared with human hepatocytes, expression of P450 in HepaRG cells was in general lower with the exception for a considerably higher expression of CYP3A4 and CYP7A1. The expression of P450s generally decreased when DMSO was removed from the medium, whereas transporters and liver-specific factors were unaffected.

Inhibited Spontaneous Emission in Solid-State Physics and Electronics

Image It has been recognized for some time that the spontaneous emission by atoms is not necessarily a fixed and immutable property of the coupling between matter and space, but that it can be controlled by modification of the properties of the radiation field. This is equally true in the solid state, where spontaneous emission plays a fundamental role in limiting the performance of semiconductor lasers, heterojunction bipolar transistors, and solar cells. If a three-dimensionally periodic dielectric structure has an electromagnetic band gap which overlaps the electronic band edge, then spontaneous emission can be rigorously forbidden. It has been recognized for some...

Enhanced Synthesis of Leukotriene B4 by Colonic Mucosa in Inflammatory Bowel Disease

Image Leukotriene B4, an arachidonic acid metabolite, is a potent chemotactic agent, and is thought to be an important mediator of inflammation. To investigate the role of this compound as a mediator of inflammation in inflammatory bowel disease, arachidonic acid was incubated with ionophore and colonic mucosa from patients with inflammatory bowel disease and from normal subjects. Mucosa from patients with inflammatory bowel disease converted 2.17% of exogenous arachidonate to leukotriene B4; mucosa from normal subjects converted 0.37%. The production of leukotriene was blocked by sulfasalazine. To determine if inflammatory bowel mucosa contained endogenous leukotriene B4 , lipid extracts were analyzed... Read More

Toxicology: Past, Present, and Future

Image Toxicology is the study of poisons and poisoning and has an ancient and venerable history. Although there have been numerous notorious poisonings throughout the ages and rather astute descriptions of toxic agents, the scientific study of toxicology did not commence until the 19th century. There was rapid development of analytical methods in the late 19th century and then an acceleration of both method and scientific development in the latter half of the 20th century. Toxicology today can be subdivided into clinical toxicology, forensic toxicology, industrial or occupational toxicology, environmental toxicology, pharmaceutical toxicology, experimental toxicology, and workplace drug testing.

This results in dietary phenylalanine rising to potentially harmful levels. It is autosomal recessive, indicating that for the disease to evolve, both copies of the gene have to be mutated. There are two main forms, classic PKU and variant PKU, depending on whether any enzyme activity remains. Those with one copy of the mutated gene usually have no symptoms. Babies should have a special formula with a small amount... Read More

Angelman syndrome

Image Angelman syndrome (AS) is a genetic disorder that mainly affects the nervous system. Angelman syndrome is due to a lack of function of part of chromosome 15 inherited from a person's mother. Most of the time, it is due to a deletion or mutation of the UBE3A gene on that chromosome. Occasionally, it is due to inheriting two copies of chromosome 15 from a person's father and none from their mother. As the father's versions are inactivated by a process known as genomic imprinting, no functional version of the gene remains. Angelman syndrome is typically due to a new mutation rather than one inherited from a person's parents. It is named after British pediatrician Harry Angelman, who first described... Read More

Children's pacemakers may be placed under the skin in one of several locations. Young children (infants, toddler, preschool, and young school-aged children) often have the pacemaker generator placed in the abdomen, since the fatty tissue found there... Read More

Narcotics

Image Narcotics The term narcotic originally referred medically to any psychoactive compound with sleep-inducing properties, and euphoric properties as well. In the United States, it has since become associated with opiates and opioids, commonly morphine and heroin, as well as derivatives of many of the compounds found within raw opium latex. The primary three are morphine, codeine, and thebaine (while thebaine itself is only very mildly psychoactive, it is a crucial precursor in the vast majority of semi-synthetic opioids, such as oxycodone or hydrocodone). Legally speaking, the term "narcotic" may be imprecisely defined and typically has negative connotations.When used in a legal context in the U.S., a narcotic drug is one that is totally prohibited, such as heroin, or one that...

ANESTHETIZED

Image ANESTHETIZED Anesthesia or anaesthesia (from Greek "without sensation") is a state of controlled, temporary loss of sensation or awareness that is induced for medical purposes. It may include some or all of analgesia (relief from or prevention of pain), paralysis (muscle relaxation), amnesia (loss of memory), and unconsciousness. A patient under the effects of anesthetic drugs is referred to as being anesthetized. Anesthesia enables the painless performance of medical procedures that would otherwise cause severe or intolerable pain to an unanesthetized patient, or would otherwise be technically unfeasible. Three broad categories of anesthesia exist: General anesthesia suppresses central nervous system activity and results in unconsciousness and total lack of sensation, using either injected or inhaled drugs. Sedation suppresses the... Read More

Bleeding Diathesis

Image In medicine bleeding diathesis is an unusual susceptibility to bleed mostly due to hypocoagulability (a condition of irregular and slow blood clotting), in turn caused by a coagulopathy (a defect in the system of coagulation). Therefore, this may result in the reduction of platelets being produced and leads to excessive bleeding. Several types of coagulopathy are distinguished, ranging from mild to lethal. Coagulopathy can be caused by thinning of the skin, such that the skin is weakened and is bruised easily and frequently without any trauma or injury to the body. Also, coagulopathy can be contributed by... Read More

It includes issues of blood donation, immunohematology and other laboratory testing for transfusion-transmitted diseases, management and monitoring of clinical transfusion practices, patient blood management, therapeutic apheresis, stem cell collections, cellular therapy, and coagulation. The blood donor centre is the facility that collects blood components from screened blood donors, either whole blood or separate components such as plasma or platelets only via apheresis. These blood components are then transported to a central location for... Read More

Myeloma

Image Multiple myeloma, also known as plasma cell myeloma, is a cancer of plasma cells, a type of white blood cell that normally produces antibodies. Often, no symptoms are noticed initially. As it progresses, bone pain, bleeding, frequent infections, and anaemia may occur. Complications may include amyloidosis. Multiple myeloma is considered treatable, but generally incurable. Remissions may be brought about with steroids, chemotherapy, targeted therapy, and stem cell transplant. Bisphosphonates and radiation therapy are sometimes used to reduce pain from bone lesions. The cause of multiple myeloma is unknown. Risk factors include obesity, radiation exposure, family history, and... Read More

Circulatory System

Image The circulatory system, also called the cardiovascular system or the vascular system, is an organ system that permits blood to circulate and transport nutrients (such as amino acids and electrolytes), oxygen, carbon dioxide, hormones, and blood cells to and from the cells in the body to provide nourishment and help in fighting diseases, stabilize temperature and pH, and maintain homeostasis. The circulatory system includes the lymphatic system, which circulates lymph. The passage of lymph takes much longer than that of blood. Blood is a fluid consisting of plasma, red blood cells, white blood cells, and platelets that... Read More

Hematopoietic stem cell transplantation

Image Hematopoietic stem cell transplantation is the transplantation of multipotent hematopoietic stem cells, usually derived from bone marrow, peripheral blood, or umbilical cord blood. It may be autologous (the patient's own stem cells are used), allogeneic (the stem cells come from a donor) or syngeneic (from an identical twin). It is most often performed for patients with certain cancers of the blood or bone marrow, such as multiple myeloma or leukaemia. In these cases, the recipient's immune system is usually destroyed with radiation or chemotherapy before the transplantation. Infection and graft-versus-host disease are major complications of allogeneic HSCT.... Read More

Coagulation

Image Coagulation, also known as clotting, is the process by which blood changes from a liquid to a gel, forming a blood clot. It potentially results in hemostasis, the cessation of blood loss from a damaged vessel, followed by repair. The mechanism of coagulation involves activation, adhesion and aggregation of platelets, as well as deposition and maturation of fibrin. The coagulation cascade of secondary hemostasis has two initial pathways which lead to fibrin formation. These are the contact activation pathway , and the tissue factor pathway (also known as the extrinsic pathway), which both lead to the same... Read More

Thrombosis

Image Thrombosis is the formation of a blood clot inside a blood vessel, obstructing the flow of blood through the circulatory system. When a blood vessel (a vein or an artery) is injured, the body uses platelets (thrombocytes) and fibrin to form a blood clot to prevent blood loss. Even when a blood vessel is not injured, blood clots may form in the body under certain conditions. A clot, or a piece of the clot, that breaks free and begins to travel around the body is known as an embolus. Thrombosis may occur in veins or in arteries... Read More

Leukemia

Image Leukemia, also spelled leukaemia, is a group of blood cancers that usually begin in the bone marrow and result in high numbers of abnormal blood cells. These blood cells are not fully developed and are called blasts or leukemia cells. Symptoms may include bleeding and bruising, feeling tired, fever, and an increased risk of infections. These symptoms occur due to a lack of normal blood cells. Diagnosis is typically made by blood tests or bone marrow biopsy. The exact cause of leukemia is unknown. A combination of genetic factors and environmental (non-inherited) factors are believed to play... Read More

Unicellular

Image A unicellular organism, also known as a single-celled organism, is an organism that consists of a single cell, unlike a multicellular organism that consists of multiple cells. Unicellular organisms fall into two general categories: prokaryotic organisms and eukaryotic organisms. Prokaryotes include bacteria and archaea. Many eukaryotes are multicellular, but the group includes the protozoa, unicellular algae, and unicellular fungi. Unicellular organisms are thought to be the oldest form of life, with early protocells possibly emerging 3.8–4 billion years ago Although some prokaryotes live in colonies, they are not specialised cells with differing functions. These organisms live together, and each cell... Read More

THE STUDY OF ARCHAEA

Image Archaeal cells have unique properties separating them from the other two domains, Bacteria and Eukaryota. Archaea are further divided into multiple recognized phyla. Classification is difficult because most have not been isolated in the laboratory and have only been detected by analysis of their nucleic acids in samples from their environment. Archaea and bacteria are generally similar in size and shape, although a few archaea have very different shapes, such as the flat and square cells of Haloquadratum walsbyi. Despite this morphological similarity to bacteria, archaea possess genes and several metabolic pathways that are more closely related to those of... Read More

Multicellular

Image Multicellular organisms are organisms that consist of more than one cell, in contrast to unicellular organisms.

Microorganisms

Image Microorganisms include all unicellular organisms and so are extremely diverse. Of the three domains of life identified by Carl Woese, all of the Archaea and Bacteria are microorganisms. These were previously grouped together in the two domain system as Prokaryotes, the other being the eukaryotes. The third domain Eukaryota includes all multicellular organisms and many unicellular protists and protozoans. Some protists are related to animals and some to green plants. They live in almost every habitat from the poles to the equator, deserts, geysers, rocks and the deep sea. Some are adapted to extremes such as very hot or very... Read More

Fungi

Image characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Similar to animals, fungi are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the Eumycota (true fungi or Eumycetes), which share a... Read More

Prevention of osteoporosis includes a proper diet during childhood and efforts to avoid medications that increase the rate of bone loss. Efforts to prevent... Read More

Insulin

Image Insulin  is a peptide hormone produced by beta cells of the pancreatic islets; it is considered to be the main anabolic hormone of the body. It regulates the metabolism of carbohydrates, fats and protein by promoting the absorption of carbohydrates, especially glucose from the blood into liver, fat and skeletal muscle cells. In these tissues the absorbed glucose is converted into either glycogen via glycogenesis or fats (triglycerides) via lipogenesis, or, in the case of the liver, into both. Glucose production and secretion by the liver is strongly inhibited by high concentrations of insulin in the blood.... Read More

Thyroid gland

Image The thyroid, or thyroid gland, is an endocrine gland in the neck consisting of two connected lobes. The lower two thirds of the lobes are connected by a thin band of tissue called the thyroid isthmus. The thyroid is located at the front of the neck, below the Adam's apple. Microscopically, the functional unit of the thyroid gland is the spherical thyroid follicle, lined with follicular cells, and occasional Para follicular cells that surround a lumen containing colloid. The thyroid gland secretes three hormones: the two thyroid hormones – triiodothyronine, and thyroxin, and a peptide hormone, calcitonin.... Read More

Overweight

Image Obesity is a medical condition in which excess body fat has accumulated to an extent that it may have a negative effect on health. People are generally considered obese when their body mass index (BMI), a measurement obtained by dividing a person's weight by the square of the person's height, is over 30 kg/m2; the range 25–30 kg/m2 is defined as overweight. Some East Asian countries use lower values. Obesity is most commonly caused by a combination of excessive food intake, lack of physical activity, and genetic susceptibility. A few cases are caused primarily by genes, endocrine... Read More

Hormones

Image A hormone is any member of a class of signaling molecules, produced by glands in multicellular organisms that are transported by the circulatory system to target distant organs to regulate physiology and behavior. Hormones serve to communicate between organs and tissues for physiological regulation and behavioral activities such as digestion, metabolism, respiration, tissue function, sensory perception, sleep, excretion, lactation, stress induction, growth and development, movement, reproduction, and mood manipulation. Hormones affect distant cells by binding to specific receptor proteins in the target cell, resulting in a change in cell function. Hormone secretion may occur in many tissues.... Read More

Hyperglycemia

Image Hyperglycemia is a condition in which an excessive amount of glucose circulates in the blood plasma. This is generally a blood sugar level higher than 11.1 mmol/l (200 mg/dl). For diabetics, glucose levels that are considered to be too hyperglycemic can vary from person to person, mainly due to the person's renal threshold of glucose and overall glucose tolerance. The degree of hyperglycemia can change over time depending on the metabolic cause, for example, impaired glucose tolerance or fasting glucose, and it can depend on treatment. Temporary hyperglycemia is often benign and asymptomatic. Blood glucose levels can rise well above normal and cause pathological and functional changes for significant... Read More

Endocrine glands

Image Endocrine glands  Endocrine glands are ductless glands of the endocrine system that secrete their products, hormones, directly into the blood. The major glands of the endocrine system include the pineal gland, pituitary gland, pancreas, ovaries, testes, thyroid gland, parathyroid gland, hypothalamus and adrenal glands. The pituitary gland hangs from the base of the brain by the pituitary stalk, and is enclosed by bone. It consists of a hormone-producing glandular portion the anterior pituitary and a neural portion the posterior pituitary, which is an extension of the hypothalamus. Four of the six anterior pituitary hormones are tropic hormones that regulate the function of other endocrine organs. Most anterior pituitary hormones exhibit a diurnal rhythm of release, which is subject to modification by stimuli influencing the hypothalamus.... Read More
