Aspirin and Prostaglandins
 
08:36
Aspirin, or acetylsalicylic acid, is one of the oldest and most well-known medications for headaches, fever, pain, and even prevention of heart attack and stroke. How does this drug cause relief of these symptoms? Check out this episode of Medicurio to learn about the quite interesting mechanism of aspirin in the body. Detailed Mechanism of Aspirin: There are two major forms of cyclooxygenase (COX) in cells. COX-1 is always made in the cell, while COX-2 is only made during inflammation. Aspirin permanently inhibits the COX-1 isoform (version) by acetylation of its active site. Therefore, aspirin’s effect lasts however long it takes for the cell to transcribe and translate new COX-1 enzymes, which usually takes a few hours. COX-1 decreases fever, pain, and inflammation, but also increases the risk of gastric ulcers by decreasing clotting and stomach mucous production. The COX-2 isoform is thought to only produce prostaglandins involved in fever, pain, and inflammation but not other functions; therefore, making a drug that inhibits COX-2 instead of COX-1 would give all the anti-inflammatory effects of aspirin without the risk of gastric ulcers. Such a drug would be a major upgrade and many companies came up with possible COX-2 inhibitors. One such drug, called rofecoxib or Vioxx, entered the market claiming that it would not cause gastric ulcers. What the drug company did not reveal was that during clinical trials, many patients suffered from heart attacks after chronic use. These problems began to surface once the general public began using Vioxx, leading to withdrawal of the drug and lawsuits against the company. Moral of the story? Research integrity is important, especially for a drug company as people’s lives are at stake. Trivia about Aspirin: It is debated if Felix Hoffmann was the true “inventor” of aspirin. Arthur Eichengrün, a fellow Bayer employee, claimed that he was the one who came up with the procedure and that Hoffmann simply performed the reaction following his guidelines. Bayer has denied this claim. Hoffmann synthesized aspirin for his father, who complained about the taste of salicylic acid that he was taking to treat his arthritis. Aspirin is extremely toxic to cats (which cannot break down aspirin) and to a lesser extent, dogs. Despite this, aspirin can still be used, just at low doses, to treat inflammation in animals. You can overdose on aspirin – at lethal doses, aspirin interferes with energy production in the mitochondria which leads to eventual death. Before death, unique symptoms such as ringing in the ears, hyperventilation, and dizziness, as well as non-specific symptoms such as vomiting and nausea appear. Overdoses are often due to chronic aspirin use, so if any of these symptoms apply to you, speak to a doctor immediately. Aspirin’s effect is increased by ingesting it with caffeine because caffeine is a stimulant, which increases blood flow to carry aspirin around the body faster and begin acting on tissue quicker. Acetaminophen (Tylenol) is not technically an NSAID because it does not decrease inflammation; however, it also works on COX enzymes so I have lumped it with the other NSAIDs in this video for simplicity.

Dietary Fats: Healthy Fat vs. Bad Fat- Thomas DeLauer
 
08:55
http://ThomasDeLauer.com Click here to subscribe to my YouTube Channel : https://www.youtube.com/thetdelauer?sub_confirmation=1 Monounsaturated Fats: Oleic Acid - Omega 9- These Protect Cell Membranes from Free Radicals. Oleic acid replaces other omega fatty acids in cell membranes. Since oleic acid is less susceptible to oxidation damage than omega-6 and omega-3 fatty acids, replacing these fatty acids with oleic acid protects your cell membranes from free radicals and other oxidative stressors (1) Palmitoleic Acid - Omega 7- These Reduce Insulin Resistance. Omega-7 protects the insulin-producing cells of the pancreas from glucose-induced toxicity - enhances proliferation of pancreatic beta cells, helping your body optimize blood sugar control with its own natural insulin (2) Reduce Inflammation- Study from the Cleveland Clinic Wellness Institute in Ohio conducted the first randomized, controlled trial in humans of supplementation with purified omega-7. Subjects were randomly assigned to receive either an omega-7 supplement providing 220 mg palmitoleic acid or a placebo - capsules were taken once daily, with a meal, and blood testing was done at the beginning of the study and again after 30 days. At 30 days, the supplemented group showed a significant mean lowering in C-reactive protein with a 44% reduction compared with the control group. Omega-7-supplemented subjects also had 15% reductions in triglyceride levels (3) Polyunsaturated Fats: Omega 3 & 6- Omega 3’s- Eicosapentaenoic acid (EPA): This 20-carbon fatty acid's main function is to produce chemicals called eicosanoids, which help reduce inflammation. EPA also helps reduce symptoms of depression. Docosahexaenoic acid (DHA): A 22-carbon fatty acid, DHA makes up about 8% of brain weight and is extremely important for normal brain development and function. EPA and DHA support cellular membranes and keep them flexible - maintaining the fluidity of the cell membranes allows for proper communication between nerve cells and, therefore, helps to support focus and mental clarity. Alpha-linolenic acid (ALA): This 18-carbon fatty acid can be converted into EPA and DHA, although the process is not very efficient. ALA is mainly used by the body for energy (4) Omega 6’s: The most common omega-6 fat is linoleic acid, which can be converted into longer omega-6 fats such as arachidonic acid (ARA) Like EPA, ARA is used to produce eicosanoids - however, the eicosanoids produced by ARA are more pro-inflammatory. Pro-inflammatory eicosanoids are important chemicals in the immune system, but when too many of them are produced, they can increase inflammation - modern Western diet contains far more omega-6 fatty acids than necessary (4) Trans Fats: Trans fats block the production of Type 1 and 3 prostaglandins (PGs), which are derived from the omega 6 and omega 3 fats, respectfully. Type 1 and 3 PGs help you fight inflammation and benefit your hormonal and nervous system (5) Saturated Fats: Studies in favor of saturated fats- A meta-analysis study, published 2010, which pooled data from 21 studies and included nearly 348,000 adults, found no difference in the risks of heart disease and stroke between people with the lowest and highest intakes of saturated fat (6) A Japanese prospective study that followed 58,000 men for an average of 14 years found no association between saturated fat intake and heart disease, and an inverse association between saturated fat and stroke (i.e. those who ate more saturated fat had a lower risk of stroke) (7) References: 1) Oleic Acid Health Benefits: MooScience.

Microbiome – Your Microbiome and Relief From Chronic Inflammation

Almost every lifestyle disease today is affected by chronic inflammation. Some researchers would say that if you can eliminate chronic inflammation, then you can significantly reduce all diseases. If this is true, then the question is: How Do You Get Relief From Chronic Inflammation? And more importantly: How Do You Prevent Chronic Inflammation? And the answer to both of these questions is centered in what is called the (icosanoid) eicosanoid pathway. Just as there is an endothelial pathway for the creation of nitric oxide for improved cardiovascular health. There is also an eicosanoid pathway that significantly influences inflammation in your body. The easiest way to understand the eicosaniod pathway is to view it as a light switch. If you want the lights on in your room (inflammation), then you flip the switch to “ON.” If you want the lights off, then you flip the switch to “OFF.” The eicosaniod pathway works the same way. This pathway helps turn on inflammation when it's needed. And once your body has used inflammation to help in the healing process, then it turn off this process. As in nitric oxide therapy were nitric oxide is the signaling molecule used to create vasodilation for improved blood flow, the eicosaniod pathway uses two signaling molecules. One that is pro-inflammatory. And one that is anti-inflammatory. Pro-inflammatory signaling molecules are produced from omega-6 fatty acids. And anti-inflammatory signaling molecules are mainly produced from omega-3 fatty acids. As outlined in our video titled how your microbiome impacts weight loss, you will remember that steps 1 and 2 directly center on this issue of omega-6 and omega-3 fatty acids. As I shared in that video: https://www.youtube.com/watch?v=NTtsjq3ks7s&t=25s Step #1 – Eliminate omega-6 vegetable oils from your diet. Ones like Corn Oil Soybean Oil Canola Oil Vegetable Oil Peanut Oil While the food industry, and our government, have tried to convince us that these omega-6 vegetable oils are safe and heart-healthy, they are not. These oils are inflammatory, and help create an environment that allow Firmicutes to flourish, which then creates toxins that your body has to address. The easiest way for your body to remove these toxins from your system is to store them in fat cells. And the more toxins your gut microbiome produces, the more fat cells your body needs to store them. The result is weight gain through larger and more fat cells. Not only do the omega-6 vegetable oils affect your microbiome and weight management, they are also the main trigger that turns on inflammation. When used properly inflammation can be a good thing as it's involved in the wound healing process. But when the “light switch” is left on, then it becomes chronic inflammation, which contributes to almost all disease processes. Now you need to do more than just eliminate these omega-6 vegetable oils from your diet. You need to do: Step #2 – Replace the omega-6 vegetable oils with omega 3 healthy fats like Coconut Oil Avocados Grass-fed Butter Fish Rich in Omega 3s Grass-fed Beef Extra-virgin Olive Oil When used in weight management studies, these healthy, anti-inflammatory omega 3 fats create an environment where healthy gut flora can dominate, which lowers inflammation levels, produces significantly less toxins, and increases the probability of weight loss. And as we've seen, they also act as signaling molecules to turn off inflammation. Omega-3 fats also play a significant role in the prevention of: Cardiovascular Disease Neurodegenrative Disorders like Alzheimer's Disease Type II Diabetes Osteoporosis Atherosclerosis Atrial Fibrillation Osteoarthritis The bottom line to all of this information is that the key to the “relief of” and “prevention of” chronic inflammation is eliminating omega-6 fats from your diet. And replacing them with omega-3 fats. This one change can have a profound health benefit for every organ and organ system in your body. As well as helping to improve your endothelial health and function for improved blood flow. And by implementing these two steps into your diet you will also significantly influence your microbiome in a positive way.

Prudence Sinclair interviews Dr. Barry Sears -  What would you do if you got cancer?

Find out what Dr. Barry Sears would do if God forbid he was diagnosed with Cancer. Subscribe to my channel to get more interviews. wwwprudenncesinclair.com Dr. Barry Sears: Dr. Barry Sears is a leading authority on the dietary control of hormonal response. A former research scientist at the Boston University School of Medicine and the Massachusetts Institute of Technology, Dr. Sears has dedicated his research efforts over the past 30 years to the study of lipids. He holds 13 U.S. Patents in the areas of intravenous drug delivery systems and hormonal regulation for the treatment of cardiovascular disease. A turning point in his research occurred in 1982. That year the Nobel Prize in Medicine was awarded for discoveries of the role that specialized hormones known as eicosanoids play in the development of cardiovascular disease, diabetes, auto-immune diseases, and cancer. Since eicosanoids are only generated from dietary fat, Dr. Sears reasoned that one could apply intravenous drug-delivery principles to nutrition in order to control these exceptionally powerful hormonal responses with laser-like precision. In essence, his approach treats food as if it were a drug. This area of his research led to various patents in the area of hormonal control by essentially using food as an oral drug-delivery system to modulate eicosanoids, especially for cardiovascular, diabetic, and neurological patients.

We aim to determine whether genetic variability in these routes may contribute to cardiovascular (CV) risk in renal transplant recipients. Methods: In a cohort of 355 patients, we determined the presence of two polymorphisms, CYP2C8*3 and CYP2J2*7, known to affect eicosanoid levels. Associations with CV mortality, CV event-free long-term survival and graft survival were retrospectively investigated by logistic regression models. Results: CYP2J2*7 showed a statistical trend towards higher CV mortality (p = .06) and lower cardiac or cerebral event-free long-term survival (p = .05), whilst CYP2C8*3 displayed a significant inverse association with the risk of CV event (hazard ratio [HR] = 0.34 [0.15–0.78], p = .01). The association of CYP2J2*7 with CV mortality became significant when the analysis was restrained to 316 patients without a history of CV events prior to transplantation (HR = 15.72 [2.83–91.94], p = .005). In this subgroup of patients both single nucleotide polymorphisms (SNPs) were significantly associated with event-free survival. HR values were 5.44 (1.60–18.51), p = .007 and 0.26 (0.09–0.75), p = .012 for CYP2J2*7 and CYP2C8*3, respectively. Conclusions: Our results show, for the first time to our knowledge, that two SNPs in CYP2C8 and CYP2J2, which synthesize EETs, may modify CV outcomes in renal transplant recipients, a population that is already at a high risk of suffering these events.

Lalita Ramakrishnan (Cambridge) 2: The Troublesome Tubercle in Tuberculosis
 
29:42
https://www.ibiology.org/human-disease/tuberculosis-pathogenesis/#part-2 Lalita Ramakrishnan gives an introduction to tuberculosis (TB) pathogenesis, gives an overview of Mycobacterium tuberculosis’ life cycle, and explains how the TB bacteria gain entry into the host. Part 1: An Introduction to Tuberculosis: The Pathogenic Personality of the Tubercle bacillus: Lalita Ramakrishnan gives an introduction to tuberculosis (TB) pathogenesis, and gives an overview of Mycobacterium tuberculosis’ life cycle. Part 2: The Troublesome Tubercle in Tuberculosis: After the tuberculosis (TB) bacteria infect macrophages, a complex structure called a granuloma develops. Ramakrishnan explains how her laboratory used a zebrafish model of TB to study the involvement of granulomas in TB progression. Part 3: Tuberculosis as an Inflammatory Disease: Lalita Ramakrishnan’s laboratory has studied the molecular pathogenesis of TB using the power of forward genetics in the zebrafish. Talk Overview: In this seminar, Dr. Lalita Ramakrishnan gives an introduction to tuberculosis (TB) pathogenesis, and gives an overview of Mycobacterium tuberculosis’ life cycle. She explains how the TB bacteria gain entry into the host by using specific lipids to avoid microbicidal macrophages and recruit growth-permissive ones. Once inside the macrophage, the bacteria use multiple virulence genes to survive intracellularly. In particular, Ramakrishnan discusses bacterial efflux pumps that, in addition to promoting intracellular survival, also induce tolerance to multiple antibiotics. Most individuals have effective counterstrategies so that they are able to clear TB infection by a combination of innate and adaptive immunity. Yet scientists have not been able to understand these defense strategies enough to harness them and create an effective vaccine against TB. After the TB bacteria infect macrophages, a complex structure called a granuloma develops. Different immune cells arrive at the granuloma to surround the bacterial infection and fight the disease. In her second lecture, Ramakrishnan explains how her laboratory used a zebrafish model of TB to study the involvement of granulomas in TB progression. Although granulomas were thought to constrain infection, her laboratory showed that the bacteria hijack the granulomas to spread the disease. For example, Ramakrishnan showed that TB bacteria promote the recruitment of new macrophages to the granuloma that engulf dying infected macrophages to expand infection. Ramakrishnan’s laboratory has studied the molecular pathogenesis of TB using the power of forward genetics in the zebrafish. They discovered that mutations in LTA4H, a key enzyme in the eicosanoid pathway that alters the levels of the cytokine tumor necrosis factor (TNF), affect tuberculosis pathogenesis by regulating the inflammatory response. This work showed that a balance of TNF is required for good TB prognosis, and neither high nor low inflammation was favorable. Correspondingly, they showed that genetic variation in LTA4H in humans helps explain patterns of TB meningitis survival when patients were exposed to a treatment that suppresses the inflammatory response. Speaker Biography: Dr. Lalita Ramakrishnan is a professor of immunology and infectious diseases at the University of Cambridge, UK. She received her medical degree from the Baroda Medical College in India, and her PhD in Immunology from Tufts University in Boston. After completing her medical residency at Tufts and a fellowship in Infectious Diseases at the University of California, San Francisco, she joined the lab of Dr. Stanley Falkow at Stanford University as a postdoctoral fellow.  There she developed Mycobacterium marinum as a model for to study tuberculosis pathogenesis. She then joined the faculty at the University of Washington, where her laboratory developed the zebrafish infected with M. marinum as a model for tuberculosis. In 2014, she moved to the University of Cambridge, where her laboratory continues to unravel the molecular underpinnings of TB pathogenesis. Ramakrishnan’s work has been recognized with several awards and honors, including the NIH Director’s Pioneer Award, the Wellcome Trust Principal Research Fellowship and election to the US National Academy of Sciences (2015).

Train With The Most Effective Methods For Six Pack Abs: http://go.sixpackabs.com/scienf9ed Check Out Thomas' Channel: http://www.YouTube.com/TheTDeLauer What's going on, SixPackAbs.com? Thomas here to talk about fat - or rather, fats - both good and bad ones. I want you to take this knowledge about fats moving forward and incorporate into the fasting lifestyle I've broken down for you in all my videos. Let's dive right in: 2:21 - Monounsaturated Fats -Monounsaturated fats are fat molecules that have one unsaturated carbon bond in the molecule, also known as a double bond. -Oils that contain monounsaturated fats are typically liquid at room temperature but start to turn solid when chilled. -Oleic Acid - Omega 9 - helps to reduce blood pressure, but occupies a particular part of a cell, making it become extra protected. -Palmitoleic Acid - Omega 7 - helps the body utilize fats more efficiently and dramatically reducing insulin resistance. -Omega-7 protects the insulin-producing cells of the pancreas from glucose-induced toxicity. -Omega-7 & Inflammation: http://www.ncbi.nlm.nih.gov/pubmed/25499944 4:35 - Polyunsaturated Fats - Omega 3 & 6 -Eicosapentaenoic Acid (EPA) in Omega 3 is a 20-carob fatty acid and its main function is to produce chemicals called eicosanoids, which help reduce inflammation. -Docosahexaenoic Acid (DHA) in Omega 3 is a 22-carbon fatty acid that makes up about 8% of brain weight and is extremely important for normal brain development and function. -Alpha-linolenic Acid (ALA) in Omega 3 is an 18-carbon fatty acid that can be converted into EPA and DHA, although the process is not very efficient. -Omega 6 is found in the so-called "healthy fats" like vegetable oil, safflower oil, canola oil, etc. -Like EPA, Omega 6 is used to produce eicosanoids - however, the eicosanoids it produces are more pro-inflammatory. 6:54 - Trans Fats -Mechanically-altered fats. -It takes 51 days to begin breaking down trans fats... -Trans fats block the production of Type 1 and 3 prostaglandins, which are derived from the omega-6 and omega-3 fats. -Stay away from Cool Whip and things that have "partially-hydrogenated soybean oil." 7:48 - Saturated Fats -Coconut oil, palm oil, and fats that come from animals that are sustained and ethically raised. -These are NOT bad. -There is zero correlation between stroke and cardiovascular risk for those that consume high levels of saturated fats as opposed to those who consume a high level of regular fats: http://ajcn.nutrition.org/content/91/3/535 The point of today's video is MODERATION. Saturated fats are good for your immune system, tremendously powerful for your brain health, and yield a plethora of other health benefits the mainstream media has led you to think otherwise about.

The Endocannabinoid System [ECS] and its Role in Metabolic Processes
 
07:41
The Endocannabinoid System: An Overview 'Marijuana has been used as a medicine for thousands of years with evidence dating back to 2000 BC, but only in the past few decades have scientists truly understood how it works. What led to this understanding was the discovery of the endocannabinoid system; a unique biological system that facilitates the effects of marijuana within the human body. The endocannabinoid system is a central regulatory system that affects a wide range of biological processes. It consists of a group of molecules known as cannabinoids as well as the cannabinoid receptors that they bind to. Although marijuana is a source of over 60 cannabinoids (including THC and CBD), the human body produces a number of cannabinoids as well. These endogenous cannabinoids include anandamide and 2-arachidonoylglycerol (2-AG) and are present in all human beings. Decades of scientific research on the endocannabinoid system has resulted in the discovery of two types of cannabinoid receptors, CB1 and CB2. These receptors are found in various parts of the body, but are most prominent in the brain and immune system. Cannabinoid receptors act as binding sites for endogenous cannabinoids as well as cannabinoids found in marijuana. When cannabinoids bind to CB1 or CB2 receptors, they act to change the way the body functions. While cannabinoid receptors are primarily expressed in the brain and immune system, researchers have identified cannabinoid receptors in a variety of other places as well, including the peripheral nervous system, cardiovascular system, reproductive system, and gastrointestinal and urinary tracts. Cannabinoid receptors continue to be identified in unique parts of the body as research on the endocannabinoid system progresses.' Full article ~ http://www.truthonpot.com/2013/03/22/the-endocannabinoid-system-an-overview/ Wiki - Endocannabinoid System 'The endocannabinoid system is a group of neuromodulatory lipids and their receptors in the brain that are involved in a variety of physiological processes including appetite, pain-sensation, mood, and memory; it mediates the psychoactive effects of cannabis and, broadly speaking, includes: The endogenous arachidonate-based lipids, anandamide (N-arachidonoylethanolamide, AEA) and 2-arachidonoylglycerol (2-AG); these are known as "endocannabinoids" and are physiological ligands for the cannabinoid receptors. Endocannabinoids are all eicosanoids. The enzymes that synthesize and degrade the endocannabinoids, such as fatty acid amide hydrolase or monoacylglycerol lipase. The cannabinoid receptors CB1 and CB2, two G protein-coupled receptors that are located in the central and peripheral nervous systems. The endocannabinoid system has been studied using genetic and pharmacological methods. These studies have revealed that cannabinoids act as neuromodulators for a variety of physiological processes, including motor learning, synaptic plasticity, appetite, and pain sensation.' Full article ~http://en.wikipedia.org/wiki/Endocannabinoid_system National Center for Biotechnology Information (NCBI) - The Endocannabinoid System as an Emerging Target of Pharmacotherapy 'The recent identification of cannabinoid receptors and their endogenous lipid ligands has triggered an exponential growth of studies exploring the endocannabinoid system and its regulatory functions in health and disease. Such studies have been greatly facilitated by the introduction of selective cannabinoid receptor antagonists and inhibitors of endocannabinoid metabolism and transport, as well as mice deficient in cannabinoid receptors or the endocannabinoid-degrading enzyme fatty acid amidohydrolase. In the past decade, the endocannabinoid system has been implicated in a growing number of physiological functions, both in the central and peripheral nervous systems and in peripheral organs. More importantly, modulating the activity of the endocannabinoid system turned out to hold therapeutic promise in a wide range of disparate diseases and pathological conditions, ranging from mood and anxiety disorders, movement disorders such as Parkinson’s and Huntington’s disease, neuropathic pain, multiple sclerosis and spinal cord injury, to cancer, atherosclerosis, myocardial infarction, stroke, hypertension, glaucoma, obesity/metabolic syndrome, and osteoporosis, to name just a few.'

NSAIDs and risk of stroke -Video abstract 54159
 
03:23
Video abstract of Review paper "Risk of stroke associated with nonsteroidal anti-inflammatory drugs" published in the open access journal Vascular Health and Risk Managment by Park K and Bavry AA. Abstract: Nonsteroidal anti-inflammatory drugs (NSAIDs), both cyclooxygenase (COX)-2-selective and nonselective agents, have been associated with the increased risk of adverse cardiovascular events. The majority of studies have focused on myocardial infarction as the primary cardiovascular outcome. However, the association between NSAIDs and the risk of stroke events is not as clear, although an understanding of this association is important since stroke continues to be a significant cause of morbidity and mortality. Various factors may contribute to an association between NSAIDs and stroke, including hypertension and thrombosis. Additionally, the risk may vary with different NSAID types. In this review, we discuss the relevant literature assessing the possible association between NSAID use and stroke events, along with the potential mechanisms and the possible directions for future study.

Lalita Ramakrishnan (Cambridge) 3: Tuberculosis as an Inflammatory Disease
 
32:27
https://www.ibiology.org/human-disease/tuberculosis-pathogenesis/#part-3 Lalita Ramakrishnan gives an introduction to tuberculosis (TB) pathogenesis, gives an overview of Mycobacterium tuberculosis’ life cycle, and explains how the TB bacteria gain entry into the host. Part 1: An Introduction to Tuberculosis: The Pathogenic Personality of the Tubercle bacillus: Lalita Ramakrishnan gives an introduction to tuberculosis (TB) pathogenesis, and gives an overview of Mycobacterium tuberculosis’ life cycle. Part 2: The Troublesome Tubercle in Tuberculosis: After the tuberculosis (TB) bacteria infect macrophages, a complex structure called a granuloma develops. Ramakrishnan explains how her laboratory used a zebrafish model of TB to study the involvement of granulomas in TB progression. Part 3: Tuberculosis as an Inflammatory Disease: Lalita Ramakrishnan’s laboratory has studied the molecular pathogenesis of TB using the power of forward genetics in the zebrafish. Talk Overview: In this seminar, Dr. Lalita Ramakrishnan gives an introduction to tuberculosis (TB) pathogenesis, and gives an overview of Mycobacterium tuberculosis’ life cycle. She explains how the TB bacteria gain entry into the host by using specific lipids to avoid microbicidal macrophages and recruit growth-permissive ones. Once inside the macrophage, the bacteria use multiple virulence genes to survive intracellularly. In particular, Ramakrishnan discusses bacterial efflux pumps that, in addition to promoting intracellular survival, also induce tolerance to multiple antibiotics. Most individuals have effective counterstrategies so that they are able to clear TB infection by a combination of innate and adaptive immunity. Yet scientists have not been able to understand these defense strategies enough to harness them and create an effective vaccine against TB. After the TB bacteria infect macrophages, a complex structure called a granuloma develops. Different immune cells arrive at the granuloma to surround the bacterial infection and fight the disease. In her second lecture, Ramakrishnan explains how her laboratory used a zebrafish model of TB to study the involvement of granulomas in TB progression. Although granulomas were thought to constrain infection, her laboratory showed that the bacteria hijack the granulomas to spread the disease. For example, Ramakrishnan showed that TB bacteria promote the recruitment of new macrophages to the granuloma that engulf dying infected macrophages to expand infection. Ramakrishnan’s laboratory has studied the molecular pathogenesis of TB using the power of forward genetics in the zebrafish. They discovered that mutations in LTA4H, a key enzyme in the eicosanoid pathway that alters the levels of the cytokine tumor necrosis factor (TNF), affect tuberculosis pathogenesis by regulating the inflammatory response. This work showed that a balance of TNF is required for good TB prognosis, and neither high nor low inflammation was favorable. Correspondingly, they showed that genetic variation in LTA4H in humans helps explain patterns of TB meningitis survival when patients were exposed to a treatment that suppresses the inflammatory response. Speaker Biography: Dr. Lalita Ramakrishnan is a professor of immunology and infectious diseases at the University of Cambridge, UK. She received her medical degree from the Baroda Medical College in India, and her PhD in Immunology from Tufts University in Boston. After completing her medical residency at Tufts and a fellowship in Infectious Diseases at the University of California, San Francisco, she joined the lab of Dr. Stanley Falkow at Stanford University as a postdoctoral fellow.  There she developed Mycobacterium marinum as a model for to study tuberculosis pathogenesis. She then joined the faculty at the University of Washington, where her laboratory developed the zebrafish infected with M. marinum as a model for tuberculosis. In 2014, she moved to the University of Cambridge, where her laboratory continues to unravel the molecular underpinnings of TB pathogenesis. Ramakrishnan’s work has been recognized with several awards and honors, including the NIH Director’s Pioneer Award, the Wellcome Trust Principal Research Fellowship and election to the US National Academy of Sciences (2015).

Histamine, Prostaglandin, Leukotrienes, Bradkinin, PGE2 LTB4 Chemotactic Factors
 
14:05
http://www.stomponstep1.com/histamine-prostaglandin-leukotrienes-bradkinin-pge2-ltb4-chemotactic-factors/ There are a groups of inflammatory signals that play key roles in the early phases of acute inflammation. These signals cause the cardinal signs of inflamation and are involved in the inflammatory mechanism. The Cardinal Signs of Inflammation are the signs and symptoms that results directly from acute inflammation. * Fever is associated with inflamation and is caused by the release of PGE2 (Prostaglandin E2), however it is not a cardinal sign of inflammation. Histamine is released from mast cells in response to cell injury, complement activation, or membrane bound IgE being crosslinked by antigen. Histamine then increases venule permeability, dilates the arterioles and prepares the vessel wall for neutrophil extravasion. In other words, Histamine is the main signal that initiates the fluid phase (But it gets helps from other cytokines). Histamine is the mediator of type 1 hypersensitive reactions (anaphylaxis & allergies) and signals stomach acid to be secretion. Antihistamines that primarily antagonize the H1 Histamine receptors are used to treat allergic symptoms, while antihistamines that primarily antagonize the H2 Histamine receptor are used to treat things like GERD and Peptic Ulcer Disease. Histamine has the help of other signals during acute inflammation. Following injury, Coagulation Factor XII (Hageman Factor) is activated by exposed collagen in the vessel wall. Factor XII then initiates the Kinin-Kallikrein System that creates Bradykinin. Bradykinin plays an important role in pain, arteriole dilation and increased venule permability during acute inflammation. We will cover elsewhere the effect coagulation factor 12 has on clotting. Angiotensin Converting Enzyme (ACE) breaks down bradykinin. Therefore, ACE Inhibitors increase bradykinin levels which can cause cough, angioedema and vasodilation. Arachidonic Acid is created when cell membrane phospholipids are acted upon by Phospholipase A2. Arachidonic Acid which is acted upon by Cycloxygenase to create Prostaglandins or Lipoxygenase to create Leukotrienes. Both classes of signal molecule play a role in acute inflammation by contributing to the fluid phase (arteriole dilation and venule permeability). PGE2 (Prostaglandin A2) is involved in the signaling process for pain and fever. LTB4, a specific type of leukotriene, is also a Chemotactic Factors which means it attracts neurtophils to the site of injury (AKA leukocytosis). The other main Chemotactic Factors are IL-8 and C5a. We will discuss prostaglandins and leukotrienes in many other videos as they are involved with the pathophysiology and treatment of many disease. Leukotrienes are involved in the pathophysiology of Asthma and their action is antagonized by receptor blocker Montelukast. Both class of molecule can be reduced to lessen the pain and inflammation. Corticosteroids inhibit Phospholipase A2 to decrease the levels of prostaglandins and Leukotrienes. NSAIDs inhibit Cyclooxygenase to decrease prostaglandin levels. Synthetic prostaglandins can be used to keep a Patent Ductus Arteriosus open in a newborn (if they have a congential heart defect that requires that route of blood flow), while an NSAID like Indomethacin can be used to close a PDA. Nuetrophils are the predominant inflammatory cell in acute inflammation. They phagocytose (engulf) infected or necrotic cells and use free radicals to destroy them. They also release granules full of proteins and enzymes that help fight infection or clear cellular debris. Neutrophils are attracted to and activated by chemotactic factors (Leukotriene B4, C5a, and Interleukin-8) created during acute inflammation. Neutrophil extravasation (AKA Leukocyte extravasation) is the process by which neutrophils exit the circulatory system into the damaged tissue. Later in the inflammatory process Macrophages use these same steps to get to the effected tissue.

While routine lipid screening plays an important role in cardiovascular risk assessment it does not provide a complete picture of your health. In fact, nearly 50% of all heart attacks and strokes occur in patients with ‘normal’ cholesterol levels. Recent evidence goes beyond lipids to suggest that inflammation within the artery wall is the primary contributor to this residual risk for heart attack and stroke. Inflammation contributes to both vulnerable plaque formation and to plaque rupture.

Importance of Measuring the Inhibition of Platelet Thromboxanes by Aspirin ...
 
01:12:47
Presented at Clinical Research & Diagnostics 2017 - https://www.labroots.com/virtual-event/clinical-diagnostics-research Luis Lopez, MD - Medical Director, Corgenix Inc. Luis R. Lopez, M.D., is the founder of Corgenix, Inc. (Broomfield, Colorado, USA) and currently serves as the Company's Medical Director. He received his MD degree in Lima, Peru, with Internal Medicine residency and postgraduate training in Clinical Immunology and Rheumatology at the University of Colorado Health Sciences Center in Denver Colorado. Dr. Lopez has worked in the field of immunodiagnostic of systemic autoimmune diseases including autoimmune-mediated atherothrombotic syndromes such as systemic lupus erythematosus (SLE) and antiphospholipid syndrome (APS). Recent work and publications have included serologic biomarkers to assess the risk of atherosclerotic cardiovascular diseases (CVD) such as oxidized low-density lipoprotein, ß2-Glycoprotein I and CRP complexes as well as pro-thrombotic platelet (urinary thromboxanes, 11dhTxB2) and inflammatory-derived F2-Isoprostanes metabolites. Importance of Measuring the Inhibition of Platelet Thromboxanes by Aspirin in Cardiovascular Disease Management and Prevention Antiplatelet therapy with aspirin (ASA) is widely used in cardiovascular disease (CVD) prevention because it inhibits platelet cyclooxygenase-1 (COX-1) and thromboxane A2 (TXA2)-mediated platelet aggregation, but not everyone fully benefit from ASA due to incomplete TXA2 suppression. Among the mechanisms to explain ASA failure (poor ASA response or ASA resistance), oxidative stress and inflammation have emerged as relevant factors. The relationship of urinary 11-dehydro-thromboxane B2 (11dhTxB2), an inactive stable metabolite of TxA2, and oxidative stress (urinary 8-isoPGF2α) in a cohort of stable coronary artery disease (CAD) patients on ASA treatment with the risk of adverse outcomes (mortality) was investigated. In this session, the effect of aspirin on platelet cyclooxygenase COX-1 and thromboxane (TxA2) inhibition, and its use in cardiovascular disease prevention will be reviewed. This review will include current laboratory measurement of urinary 11dhTxB2, a stable inactive metabolite of TxA2, to assess ASA response as a risk factor of CVD including mortality. Study results confirmed that laboratory measurement of urinary 11dhTxB2 represents a strong independent risk factor for all-cause mortality among stable CAD patients on ASA therapy. These results also indicate that 8-isoPGF2α and COX-2 thromboxane production not affected by ASA may maintain platelet hyperactivity irrespective of COX-1 inhibition. Poor ASA inhibition of 11dhTxB2 (ASA resistance) may prompt additional anti-oxidative and/or anti-inflammatory therapy in these patients aimed at modifying 5-year mortality risk.
