Introduction Autoimmune Disease by Dr. Kelly Cobb
The immune system represents an interface between a constant ever-changing external environment and an internal system that is striving to maintain homeostasis and defend its boundaries from harmful foreign invaders.
Nutraceuticals, gene expression and healthy aging
The document discusses healthy aging and the effects of nutraceuticals on gene expression. It covers several topics related to aging including the hallmarks of aging like inflammation, glycation, methylation, and oxidative stress. It provides information on maintaining healthy aging through diet, nutraceutical supplementation, and exercise. Tips are given on anti-inflammatory herbs, foods rich in omega-3, and ways to reduce advanced glycation end products and chronic inflammation.
[Challenge:Future] A death instead of the evolution
Modern medicine and lifestyle changes have decreased human lifespans contrary to expectations of continued evolution and longevity. Ancestors faced physical challenges and epidemics but led active lives without processed foods, smoking, or sedentary lifestyles. The WHO now considers 75-90 as an broad age range for being elderly rather than a sign of old age before 75 due to decreased average lifespans from modern conveniences and health risks despite medical advancements.

This document discusses malaria and new generations of anti-malarial drugs. It defines malaria as a sickness caused by the bite of a female Anopheles mosquito, which transmits Plasmodium parasites. The most dangerous species is P. falciparum, which can accumulate in vital organs and cause death. Artemisinin was discovered in the 1960s-1970s and acts by releasing reactive radicals when it comes into contact with iron in the parasite, destroying it. Chloroquine was discovered earlier but became widely used in 1946; it prevents toxic haem groups from accumulating in red blood cells and kills the parasite, though resistance has developed.

Structural elucidation is the determination of the chemical structure of uncharacterized substances such as natural products. It uses various chromatography and spectrometric techniques including MPLC, HPLC, MS, 1D and 2D NMR. Spectroscopic methods like NMR, IR, MS, UV-Vis are the main tools used to identify molecular structures, monitor reactions, and analyze purity. These techniques can determine functional groups, molecular weights, and apply empirical rules to quantify substituent effects and elucidate unknown structures. Concentrations are also measured spectrophotometrically using Beer-Lambert's law.
Medicinal Species of the Genus Artemisia
This document summarizes several medicinal species from the genus Artemisia. It discusses five species - wormwood (Artemisia absinthium), sweet Annie (Artemisia annua), mugwort (Artemisia vulgaris), white mugwort (Artemisia ludoviciana), and tarragon (Artemisia dracunculus). For each species, it provides distinguishing characteristics, geographic range, traditional uses, and medicinal properties. Key points include wormwood's use in absinthe and magic, sweet Annie's role in treating malaria, and the uses of mugwort and white mugwort in Traditional Chinese Medicine and Native American traditions.
journal :Artemisinin resistance in se asia
The document summarizes a study on the spread of artemisinin resistance in Plasmodium falciparum malaria. The study found:
1) Parasite clearance rates varied significantly between sites in Southeast Asia, with the slowest clearance in western Cambodia and eastern Thailand, indicating higher levels of resistance.
2) Resistance has spread from western Cambodia to other parts of mainland Southeast Asia but was much lower or absent elsewhere studied, including Africa.
3) Genetic markers were identified that correlate parasite clearance rates with mutations, helping define the current extent and severity of artemisinin resistance globally.
Semi synthetic artemisinin_Dr. Mansij Biswas
This document summarizes the history and development of semi-synthetic artemisinin as an antimalarial drug. It discusses how artemisinin was originally extracted from sweet wormwood but is now partially produced synthetically through fermentation and chemical conversion. This has made the drug more stable in supply and lower in price, improving access for developing countries. The development involved researchers at UC Berkeley, Amyris, Sanofi, and was funded through partnerships including the Bill & Melinda Gates Foundation. The semi-synthetic production method is expected to provide a steady supply of artemisinin to treat millions annually.

Immune Deficiency
Immune deficiency occurs when the immune system is weakened or not functioning properly. There are two main types - primary and secondary immune deficiency. Primary immune deficiency is present from birth and can involve deficiencies in phagocytic cells, B cells, or T cells. Secondary immune deficiency develops due to external factors like infections, malnutrition, or drugs. Common symptoms include recurrent infections of the skin, lungs, sinuses and other organs. Diagnosis involves medical history, exams, and lab tests. Treatment depends on the underlying cause but may include antibiotics, immunoglobulin replacement therapy, stem cell transplants, or gene therapy.
The Immune System & Nature's Sunshine Supplements
The document discusses the human immune system and concerns about immune function. It describes the immune system as a complex network of cells, tissues, and organs that protect the body. The main concerns discussed are the rise of antibiotic-resistant infections, lack of new antibiotic development, toxic exposures, stress, sleep deprivation, sedentary lifestyles, and nutrient-poor diets. The document then summarizes the functions of the immune system and key cells involved in immune responses. It emphasizes establishing a healthy lifestyle and diet to support optimal immune function.
Pernicious anemia
A decrease in red blood cells when the body can't absorb enough red blood cells.It is an organ specific autoimmune diseases in which the body’s immune system attacks the lining of the stomach.
It was considered as a deadly disease due to the lack of available treatment.
Pernicious anemia is most common in caucasian persons of north European ancestry than in other racial groups.
Nutrition for human immune system
This document discusses how proper nutrition is essential for supporting the human immune system. It outlines the key cells and components of the immune system and explains how certain nutrients like protein, vitamins, minerals, antioxidants and phytonutrients promote immune function. Maintaining adequate intake of these nutrients through a diet high in foods like eggs, fish, citrus fruits and vegetables can help the immune system fight infections and disease.
Immunity THE BODY’S DEFENSES
The document discusses the body's defense mechanisms against disease. It describes three lines of defense: external barriers like skin and mucus, internal barriers like stomach acid, and the immune system. The immune system uses nonspecific defenses like phagocytes and the inflammatory response. It also has specific immune defenses like antibodies and lymphocytes. Antibodies provide humoral immunity while lymphocytes provide cell-mediated immunity. The document also covers immune system disorders like allergies and AIDS.
AUTOIMMUNITY
Autoimmunity occurs when the immune system attacks the body's own tissues and organs. In an autoimmune disease, antibodies produced by the immune system called autoantibodies mistakenly attack healthy cells in the body. Common autoimmune diseases include type 1 diabetes, Hashimoto's disease, multiple sclerosis, Graves' disease, rheumatoid arthritis, and systemic lupus erythematosus. The causes of autoimmunity are complex and involve genetic, environmental, and hormonal factors. Current treatments aim to reduce symptoms by suppressing the overactive immune response through medications like steroids, immunosuppressants, or plasmapheresis.
Microbiology and Infectious Disease
The document provides an overview of the immune system and infectious diseases. It discusses the immune system's first-line defenses like skin and internal barriers. When pathogens breach these defenses, the immune system mounts specific responses through lymphocytes and antibodies. Vaccines provide active immunity by exposing the body to antigens in a controlled way. The document also discusses how microorganisms were first observed under microscopes and how scientists later linked bacteria, viruses and other microbes to transmitting infectious diseases.
L6_immunity__system.ppt
The immune system has both innate (non-specific) defenses and adaptive (specific) defenses. The innate system uses physical and chemical barriers like skin and mucus as well as cells that attack foreign substances. If pathogens breach these defenses, the adaptive system mounts an antigen-specific response using B cells, T cells, and antibodies. Vaccines help active immunity develop by exposing the body to antigens without causing disease. The immune system defends the body but can also cause issues like allergies and asthma when improperly activated.

Immunochemistry
Immunochemistry involves the study of the molecular mechanisms of the immune system, especially antibodies, antigens, and their interactions. The document defines innate and active/passive immunity. Innate immunity refers to nonspecific defenses like skin, chemicals, and immune cells that attack foreign cells. Active immunity results from antibody production when exposed to an antigen, while passive immunity involves the transfer of readymade antibodies. The mechanisms of the immune system include physical barriers, chemicals, blood cells, macrophages, inflammation, fever, interferons, natural killer cells, and the complement system.
AQA GCSE Science: Biology B1 Revision
A combination of a balanced diet and regular exercise is needed to help keep the body healthy and defend against infectious diseases. Our bodies have multiple lines of defense against pathogens like bacteria and viruses, including physical barriers, chemicals, white blood cells, and immunity through vaccination or previous exposure. However, some bacteria are developing resistance to antibiotics, so they should now only be used to treat serious infections.
Lymphoid system and cytokines
The lymphatic system is a network of tissues and organs that help rid the body of toxins, waste and other unwanted materials. The primary function of the lymphatic system is to transport lymph, a fluid containing infection-fighting white blood cells, throughout the body.
Ch 43 immunity
This document provides an overview of the human immune system and its defenses against disease. It discusses the external barriers of skin and mucus, internal responses like phagocytosis and inflammation, and the adaptive immune system involving B and T cells and antibody production. It covers active and passive immunity, immune responses, antigen recognition, and immune system disorders like autoimmunity, allergy, and AIDS. The immune system provides multilayered defenses that have largely evolved to protect the body from infectious diseases, toxins, and other foreign invaders.

The document discusses the immune system and pathogens. It describes how the immune system responds to antigens through nonspecific defenses like skin and mucus membranes, and specific defenses using white blood cells and antibodies. Pathogens that can cause disease include bacteria, viruses, fungi, protozoa, and worms. They are transmitted through various methods like air, food, water, direct contact, needles, or animals. The immune system mounts its defense through phagocytes that destroy microbes, interferon that inhibits viruses, and lymphocytes that produce antibodies for specific pathogens. Disorders like HIV/AIDS occur when the immune system is compromised, such as by a retrovirus like HIV that attacks T-cells.
Autoimmunity
This document discusses autoimmunity and autoimmune diseases. It begins by explaining how the immune system can mistakenly attack self-antigens, leading to autoimmunity. Several organ-specific and systemic autoimmune diseases are described in detail, including how they are mediated by direct cellular damage, stimulating or blocking autoantibodies. Current treatments aim to suppress the immune system generally but do not cure the underlying condition. Experimental therapies discussed include T-cell vaccination, peptide blockade of MHC molecules, and monoclonal antibodies.
