Diarrhea is the condition characterized by atleast three liquid or loose bowel movements each day. It typically lasts for a few days and can result in dehydration owing to fluid loss. Diarrhea is of three types- short duration bloody diarrhea, short duration watery diarrhea and persistent diarrhea. Irritable behavior and loss of the normal stretchiness of the skin are common signs of the disease. If it becomes severe, it can result in decreased urination, fast heart rate, loss of skin color and decrease in responsiveness. The underlying cause of the disease can be attributed to an infection of the intestines. Lactose intolerance, non-celiac gluten sensitivity, irritable bowel syndrome, celiac disease, hyperthyroidism, bile acid diarrhea, etc. are other causes of diarrhea. Oral rehydration solution and zinc tablets are ideal treatment strategies for diarrhea. This book is a comprehensive clinical guide to diarrhea. The topics included herein are of utmost significance and bound to provide incredible insights to readers. This book is appropriate for students seeking detailed information on this medical condition as well as for experts.

Chemotherapy is a form of chemical drug therapy that is used to destroy rapidly growing cells of a body. It is a systemic therapy as it affects the whole body. It is primarily used in the treatment of cancer. However, it can also be used in the treatment of immune system disorders, such as rheumatoid arthritis or lupus. It lowers the number of cancer cells in the body, reduces metastasis, shrinks the tumor and reduces symptoms. When cancer is at an advanced stage, chemotherapy is used to relieve pain and symptoms. It can be delivered directly into the tumor to a specific part of the body through localized treatment, or administered orally, topically or in single shots. Due to its systemic nature, chemotherapy drugs target the cells in the blood, lining of the intestinal tract, the skin and the hair as well as where fast growing cells reside. This leads to side effects such as diarrhea, fatigue, mouth sores, easy bruising and bleeding, dry mouth, neuropathy, infections, memory problems, etc. Though many of these symptoms subside after conclusion of the treatment, damage to internal organs may also be incurred. This book elucidates new techniques and applications of chemotherapy in a multidisciplinary manner.

Cancer immunotherapy is a growing field of oncology that is concerned with the artificial stimulation of the immune system for the treatment of cancer. This is achieved by enhancing the body's natural ability to fight cancer. In cancer immunotherapy, antibody proteins of the immune system detect cancer cells by binding to them. The chief difference between normal and modified immunotherapy antibodies lies in the fact that while the former binds to external pathogens, the latter binds to tumor antigens thereby identifying and marking the cancer cells for the immune system to kill or inhibit their growth. Cancer immunotherapy can be passive, hybrid or active. Hybrid therapy is a combination of active and passive therapies. In active immunotherapy, the immune system is directed to attack tumor cells by targeting tumor antigens. Passive immunotherapies improve existing anti-tumor responses by using lymphocytes, cytokines and monoclonal antibodies. Some of the approved immunotherapy antibodies are nivolumab, alemtuzumab, ofatumumab, ipilimumab and rituximab. This book elucidates new techniques and applications of cancer immunotherapy in a multidisciplinary manner. It explores all the important aspects of cancer immunotherapy research and practice in the present day scenario. It will prove to be immensely beneficial to students and researchers in this field.

The condition characterized by the abnormal enlargement or thickening of the heart muscle that results from an increase in the size of cardiomyocyte and changes in other heart muscle components like the extracellular matrix is termed as cardiac hypertrophy.

HIV or human immunodeficiency virus is the cause of HIV/AIDS. It is a retrovirus, which infects the human immune system, particularly the CD4+ T cells, macrophages and dendritic cells. HIV is of two types- HIV-1 and HIV-2. HIV-1 is more infective and virulent. It causes the majority of HIV infections worldwide. HIV-2 is comparatively less pathogenic than HIV-1 and has lower transmission rates. However, both lead to AIDS in individuals and also mutate to develop drug resistance. Once HIV enters the body, it undergoes a period of rapid viral replication, which then reduces CD4+ T cells. This results in a weakening of the immune system, thus allowing opportunistic infections to occur. The treatment of AIDS aims at slowing the progression of the disease, using antiretroviral therapy. This therapy consists of a combination of at least two classes of antiretroviral agents, non-nucleoside reverse transcriptase inhibitor and nucleoside analog reverse transcriptase inhibitors. This book covers in detail some existing theories and innovative concepts revolving around HIV medicine. Different approaches, evaluations, methodologies and advanced studies on HIV/AIDS and its management have been included herein.

Living organisms require oxygen for survival, but it is also a highly reactive molecule that can damage organisms by producing reactive oxygen species. Oxidation is the chemical reaction that produces free radicals and thereby leads to chain reactions with the potential to damage the cells of organisms. Antioxidants inhibit oxidation. Ascorbic acid or thiols are antioxidants that can terminate these chain reactions. Organisms have a complex system of antioxidant metabolites and enzymes that work in tandem to prevent oxidative damage to DNA, proteins and lipids. However, reactive oxygen species have useful cellular functions as well, such as redox signaling. Antioxidant systems therefore do not remove oxidants completely but keep them at an optimum level. The role of oxidative stress in degenerative diseases, such as diabetes, kidney disease, neurological disorders, obesity, cancer and aging is understood. This makes antioxidant dietary supplements a potential strategy to overcome these conditions. This book provides comprehensive insights into antioxidants and their role in human health and disease. It will also provide interesting topics for research, which interested readers can take up. With state-of-the-art inputs by acclaimed experts of this field, this book targets students and professionals.
