A chat with neurotologist Dr. Kenneth Brookler MD #Insulin #Tinnitus #Ménière's Disease Fixes
Dropping by New York I took the opportunity to have another enjoyable chat with Dr. Brookler. Since our last meeting, he has been focussing in on the clinical effects of low-carb, high-fat diets. He is seeing some impressive outcomes from the approach ! He has also been researching insulin's effects on endoplasmic reticulum stress, particularly that in the beta cells of the pancreas. It speaks to the mechanisms by which hyperinsulinemia wreaks havoc, leading to the chronic diseases of the insulin resistant state.

Peter Walter (UCSF/HHMI): Unfolding the UPR
https://www.ibiology.org/cell-biology/unfolded-protein-response/ Proteins that are secreted from the cell or inserted into the plasma membrane, transit through the endoplasmic reticulum where they are properly folded and assembled and may undergo post-translational modification. Walter tells the story of the exciting discovery made in his lab of the "unfolded protein response", a feedback pathway that ensures that the cell makes enough ER to properly modify all the secreted proteins in the cell.

Diabetes Mellitus Type 1 for USMLE Step1 and USMLE Step 2
Handwritten Video Lectures on the pathophysiology, pathology, symptoms and treatment of Diabetes Mellitus Type 1 for USMLE Step 1 and Step 2. PHYSIOLOGY OF DIABETES MELLITUS TYPE 1 Islet cells have beta cells in the central which secrete insulin and beta cells which secrete glucagon. The beta cells has the GLUT2 transporter which transports glucose inside the cell. It is then acted upon by glucokinase which increases the level of ATP. ATP then deactivates KATP channels. Afterwards Calcium inlux activates vesicles of insulin to fuse with the membrane and release the insulin. Insulin is synthesized in the Rough Endoplasmic reticulum as the preproinsulin. After removla of the pre and the post Peptides to form proinsulin. After the golgi aparatus the c peptide bends over and is removed after a bond is formed between the a and b peptide. The c-peptide is a measure of endogenous insulin production. PATHOPHYSIOLOGY OF DIABETES MELLITUS TYPE 1 Destruction of the Islet Cells of Langerhan leads to hypglycemia. The genetic component of Diabetes Mellitus Type 1 involves HLA-DR3 and HLA-DR4. Autoimmune is also invovled in Diabetes Mellitus Type 1. Islet cell autoantibodies target insulin or Anti GAD65. Also Diabetes Mellitus is associated with other autoimmune disease. Viruses such as cocksackie virus also is known to cause Diabetes Mellitus. DIAGNOSIS OF DIABETES MELLITUS TYPE 1 HbA1c level greater then 6.5 percent 2 hour fasting glucose greater than 126 mgdL Oral Glucose Tolerance Test (OGTT) greater than 200 Random Plasma Glucose greater than 200 and symptomatic Anyone 1 of the previous is a diagnosis of Diabetes Mellitus SIGN AND SYMPTOMS OF DIABETES MELLITUS TYPE 1 Primary symptoms are polyuria polydypsia and weight loss occurs in approximately 90 percent of patients. Other symptoms include hyperphagia, perianal candidiasis. Diabetic Ketoacidosis also has polyuria, polydipsia, fruity death and neurological symptoms COMPLICATION OF DIABETES MELLITUS Diabetic patients who do no manage their glucose well may get diabetic neuropathy, diabetic nephropathy, diabetic retinopathy, necrobiosis lipoidica and increase risk of atherosclerosis MANAGEMENT OF DIABETES MELLITUS Insulin therapy with a goal of keeping HbA1c below 7 percent. Fast Acting Insulin includes Aspart, Lispro and Glulysine Intermediate Acting Insulin such as regular insulin and NPH Long acting insulin includes Glargine which has no peak, Determir which binds to albumin may all be using in different combination to manage glucose levels in Diabetic patients.

Insulin Secretion Beta Cell - Diabetes
This animation shows the regulation of insulin secretion in a beta cell. Glucose is transported via the glucose transporter GLUT2 into the cell. The enzyme glucokinase converts the glucose to glucose-6-phosphate. During glycolysis glucose-6-phosphate is metabolized and ATP as well as pyruvate are generated. The pyruvate is transported into the mitochondria where it is converted to acetyl CoA so it can enter the citric acid cycle. During the citric acid cycle more ATP is generated. The ATP-sensitive potassium channel regulates the transport of potassium ions. The elevated concentration of ATP in the cell leads to the closing of the potassium channel, thereby inducing membrane depolarization. The depolarization triggers the opening of the voltage-gated calcium channel. The influx of Ca2+ ions as well as their triggered release from the endoplasmic reticulum leads to the fusion of the insulin vesicles with the cell membrane, thereby releasing the insulin.

What Causes Diabetes?
Hi , Welcome to our YOUTUBE channel. Here we are going to tell you what causes the Diabetes. In this video we will tell you about the main causes of diabetes. The population of islet cells is established and not plastic in man after about age 20 years. Post mortem studies show that the B cell number at diagnosis of type 2 diabetes is around 50% and decreases to around 20 % after many years. A chronic increase in plasma FFA levels is harmful as shown by the important effects of these dietary components in pancreatic bet6a cell lipotoxicity. Fatty acid derivative can interfere with function of these cells and ultimately lead to their death through lipoapoptosis. Saturated fat is very harmful as compared to unsaturated fats. Saturated fats are harmful to beta cells which help in the production of insulin. The endocytosis of LDL can cause beta cell death as a result of ROS formation. Western diets rich in saturated fats cause obesity and insulin resistance and increase levels of circulating NEFAs . In addition they contribute to b cells failure in generally predisposed individuals. NEFAs cause beta cell apoptosis and may thus contribute to progressive Beat cell loss in type 2 diabetes. Type 2 diabetes is characterized by defects in both insulin secretion and insulin action but saturated fat effects the both. SFA ingestion reduced insulin sensitivity. Pancreas should increase insulin production but insulin secretion failed to compensate for insulin resistance in subjects who ingested SFA. Failure of insulin secretion to compensate for insulin resistance implies impaired beta cell function in the SFA study. Increased consumption of SFAs has a powerful short and long term effect on insulin action. Saturated fats are harmful to beta cells. Environmental factors such as diets rich in saturated fats contribute to dysfunction and death of pancreatic beta cells in diabetes, Endoplasmic reticulum stress is elicited in beta cells by saturated fatty acids.

Benefits of Olive Oil Consumption in Type 2 Diabetes Treatment.
Worldwide, type 2 diabetes is at epidemic proportions, with over 300 million already having the condition with an estimated rise to 600 million diagnosed cases by the year 2030. Information regarding reduced risk of type 2 diabetes is fairly common. However, finding information regarding treatment and management for an individual who already has type 2 diabetes can be somewhat more difficult. Therefore, this article is designed as a mini literature review of sorts, pointing to some of the recent research around olive oil and its potential benefits for use as a dietary intervention in type 2 diabetes treatment. Endoplasmic reticulum stress (ER) is a central mediator for pancreatic beta-cell dysfunction in type 2 diabetes. An in vitro study published in Biochemical and Biophysical Research Communications, 2016, investigated if tyrosol, an antioxidant polyphenolic compound found in olive oil, could protect against beta-cell dysfunction. Researchers found that tyrosol did in fact protect against beta-cell ER stress-induced cell death, suggesting that it should be explored as a therapeutic agent for improving insulin resistance and diabetes. Insulin resistance (IR) is one of the major contributors to difficulties in maintaining blood glucose control. A study published in Diabetologia, 2015, randomized 642 patients to either an olive oil enriched Mediterranean diet (MedDiet) (35 percent fat; 22 percent from monounsaturated fat) or a low-fat diet (less than 28 percent fat) to determine whether dietary intervention effects tissue-specific IR and beta-cell function. The study found that both diets improved IR, however, liver IR is improved more through a low-fat diet, while muscle IR and muscle+liver IR could benefit more from the olive oil enriched MedDiet. At this point there are no clinical trials evaluating the role of dietary patterns on the incidence of microvascular complications such as retinopathy and nephropathy in type 2 diabetes. A post hoc analysis of a cohort of type 2 diabetic participants, published in Diabetes Care, 2015, shows that a MedDiet supplemented with EVOO may protect against diabetic retinopathy, a complication leading to blindness, but not nephropathy. According to a detailed review of 2824 studies, published in the British Medical Journal, 2015, consuming a MedDiet is associated with better glycaemic control and cardiovascular risk factors, even compared to a lower fat diet. Clinical conditions associated with obesity, such as type 2 diabetes, show improvements with daily intake of conjugated linoleic acid (CLA) or extra virgin olive oil (EVOO). A study on mice published in The Journal of Nutritional Biochemistry, 2015, investigated whether dietary supplementation of CLA or EVOO could change body metabolism associated with mitochondrial energetics. The study found that while EVOO alone did not change any metabolic parameter, combined with CLA it protects against IR and liver enlargement, while the CLA improves mitochondrial action and body metabolism. According to research published in Biochimia et Biophysica Acta, 2014, oleic acid, a major biological component in olive oil, is a primary component of membrane lipids and helps to regulate membrane structures by having the ability to incorporate into phospholipids, which has various advantages to cell composition. It is also thought that membranes rich in oleic acid have increased flexibility to promote GLUT4 glucose transport into cells and help reverse saturated fatty acid-induced IR.

What Are Diabetes Causes
Hi, Welcome to our YOUTUBE channel. Here we are going to tell you about various causes of diabetes. In this video we will tell you all the causes related to diabetes. After the age of 20, the population of islet cells is established and not plastic in man after age of 20 years. Post mortem studies show that beta cell number at diagnosis of type 2 diabetes is around 50 percent and decreases to around after many years. Exposure of human islet to fatty acid causes an increase in intra islet fat storage and marker of apoptosis. Saturated cells contributed more in death of beta cells. Saturated lipids are harmful to beta cells. The endocytosis of LDL can cause beta cell death as a result of ROS formation. Similarly, prolonged elevation of circulating NEFAs by lipid infusion impairs pancreatic beta cell function in vivo, particularly in individuals with a genetic predisposition to type2 diabetes. Western diets rich in saturated fats cause obesity and insulin resistance and increase levels of circulating NEFAs . In addition they contribute to beta cells failure in genetically predisposed individuals. NEFAs cause beta cell apoptosis and may thus contribute to progressive beta cell loss in type 2 diabetes. Type 2 diabetes is characterized by defects in both insulin secretion and insulin action. SFA ingestion reduced insulin sensitivity. Insulin secretion failed to compensate for insulin resistance in subjects who ingested SFA. Failure of insulin secretion to compensate for insulin resistance implies impaired beta cell function in the SFA. Increased consumption of SFAs has a powerful short and long term effect on insulin action. Saturated fats are harmful to insulin. Environmental factors such as diets rich in saturated fats contribute to dysfunction and death of pancreatic cells in diabetes.

There are many structures with specific functions. Dr. Berg explains these structures and breaks down the complexities. 1. Nucleus: DNA 2. RNA 3. Mitochondria 4. Endoplasmic Reticulum 5. Ribosomes 6. Glogi Apparatus 7. Lysosome 8. Peroxisome 9. Membranes Hey guys, I wanted to create a little video on your cells because it can be very complicated, I am gonna try to simplify it. There’s various parts of the cell, it is like a universe there are all sorts of things that’s happening. You have the center part which is called the nucleus and in the nucleus, you have what it’s called the DNA. The DNA is basically gonna give a program to tell what the rest of the cell should do as far as what the body tissue to make and what actions to perform. Then we have what’s called the RNA, there’s three different kinds but just to simplify it, you look at the RNA as the copy of the DNA. You have the copy machine of your cells. So it makes the copy of the code and then it paste it to the certain transport units that send it out to the rest of the cells. So just like the computer programmer that would write his certain code and maybe cut and paste it to the different thing to make a website, your body has an RNA to do that as well. Now it is even more amazing is the DNA and RNA could have over 10,000 errors every single day from things like radiation, chemicals, to things that oxidizes the cells, free radical damage, etc. But we have an entire repair unit in the cell that could go in there like a proofreader read the code translate the code and look for errors. Then it will cut out the section of errors replace it with new one or fuse it together. And there’s another proofreader unit that comes behind the initial proofreader to make sure they didn’t make any errors to look and read the code to make sure it is exact and they also have the capacity to cut out the bad code, put in the new code and replace it to the point that you can reduce the errors to 1 in a billion. This is incredible because when the errors are there, you have this mutation which are alterations of the code and that can lead to cancer and a lot of other diseases. Next thing we are going to talk about is the mitochondria. The mitochondria is the energy factory of the cell. It takes your foods, mixes the oxygen and it produces energy. In the body, the energy is called ATP. It is kind of the energy currency. And then you have something called the Endoplasmic Reticulum which is the part of the cell that either makes protein if its the rough part of makes lipids or steroid if its the smooth part. Because a lot of your body tissue is composed of fat and protein Hair, Nails, Brain, Nerve, etc. So this is one part of the assembly aligned in the manufacturing of the body tissue and then we have this little things called ribosomes which are basically protein making machines on steroid so they actually help in making different protein structures not just for body parts but for body chemicals like hormones, neurotransmitters, blood cells, you name it. Then we have something called the Golgi Apparatus. Dr. Eric Berg DC Bio: Dr. Berg, 52 years of age is a chiropractor who specializes in Healthy Ketosis & Intermittent Fasting.

Satchin's work deals specifically with the timing of food and it's relationship with our biological clocks governed by circadian rhythm and also the circadian rhythm in general. ▶︎ Get the show notes! https://www.foundmyfitness.com/episodes/satchin-panda In this video we discuss... •The fascinating history of experimentation that ultimately elucidated the location for the region of the brain necessary for a properly timed sleep-wake cycles. • The relationship between our body's "master clock" and it's many peripheral clocks. • Why infants sleep so intermittently, instead of resting for a longer, sustained duration like healthy young adults... and why this sustained rest also goes haywire in the elderly. • The fascinating work Dr. Panda took part in that lead to the discovery of a specialized light receptor in the eye that sets circadian rhythms and is known as melanopsin. • The important relationship between the relatively light insensitive melanopsin, which requires around 1,000 lux of light to be fully activated, and its control of the circadian clock by means of activation of the suprachiasmatic nucleus and suppression of melatonin. • The effects light exposure seems to have on next-day cortisol, a glucocorticoid hormone that regulates around 10-20% of the human protein-encoding genome. • The clever experimental design by which Dr. Panda and his colleagues discovered that certain circadian rhythms, especially of the liver, are entrained by when we eat, instead of how much light we get. This underlines the fact that, when managing are circadian rhythm, both elements are important! • One of the more surprising effects of time-restricted feeding in mice eating a so-called healthy diet: increases in muscle mass and even endurance in some cases.

ZsoltRonai - Polymorphic miRNA binding sites in the WFS1 gene...
Watch this Webinar on Labroots at http://www.labroots.com/virtual-event/genetics-genomics-2016 Wolframin is a major protein of the endoplasmic reticulum, it is expressed in most tissues and clinical data demonstrate its significant connection to diabetes mellitus. Loss of function mutations of the WFS1 gene result in the monogenic Wolfram-syndrome, characterized by optic atrophy, diabetes insipidus, early onset diabetes mellitus and deafness. Accordingly, polymorphic variants of the gene, which cause only minor alterations in protein function, are putative risk factors of diabetes. This presentation focuses on the association and molecular analysis of two SNPs (rs1046322 and rs9457) in the 3’ UTR region of the WFS1 gene, which are supposed to alter the binding of miRNA-668 and miRNA-185, respectively, based on in-silico data. Association analysis of the polymorphic loci and diabetes mellitus was carried out on 617 patients and 1147 health controls in the study. Genotype analysis was carried out using PCR and single base extension (SBE) reaction using the GenomeLab GeXP™ Genetic Analyzer. Functional analysis of miRNA binding was investigated by luciferase reporter system. The results suggested that rs9457 SNP “C” allele was significantly more frequent among patients with type 2 diabetes mellitus (p = 0.0008), whereas the rs1046322 variant showed a significant association with the type 1 form of the disease. Haplotype analysis confirmed the roles of the polymorphic variants in the genetic background of diabetes. In addition, the luciferase reporter experiments confirmed the data of the sequence analysis in where the rs1046322 and the rs9457 SNPs altered the binding of miRNA-668 and miRNA-185, respectively. Earlier studies indicated an association between a third variant of the 3’ UTR (rs1046320) and diabetes; however no biological function of the SNP could be observed. This is probably due to the strong linkage disequilibrium between rs9457 and rs1046322, thus the latter polymorphism could be a potential genetic marker of rs9457 miRNA-SNP.

For details, see http://ecampus.oregonstate.edu/soc/ecatalog/ecourselist.htm?termcode=all&subject=BB 9. Course materials at http://davincipress.com/bb450.html Highlights - Fatty Acid Oxidation 1. Fats are broken down to fatty acids and glycerol by enzymes known as lipases. Hormone sensitive triacylglycerol lipase is the only regulated enzyme of fat or fatty acid breakdown. 2. Triacylglycerol lipase action cleaves the first fatty acid off of a fat and this step is necessary before the other lipase can act to remove the other fatty acids from a fat. 3. Fatty acid oxidation occurs in the matrix of the mitochondrion. In the cell, fatty acids are attached to CoA and then at the mitochondrion, the CoA is replaced by carnitine. Inside the mitochondrial matrix, the carnitine is replace by CoA again. 4. Steps in fatty acid oxidation include dehydrogenation, hydration, oxidation, and thiolytic cleavage. The dehydrogenation and oxidation reactions yield reduced electron carriers. Thiolytic cleavage is catalyzed by the enzyme called thiolase. 5. The first reaction of fatty acid oxidation involves acyl dehydrogenases. These are specific for fatty acids with long, medium, or short chains. The medium chain acyl dehydrogenase has been implicated in some instances of sudden infant death syndrome. 6. The long chain acyl dehydrogenases are found in peroxisomes and this is where oxidation of long chain fatty acids (longer than 16 carbons) begins. Oxidation involves transfer of electrons to oxygen to make hydrogen peroxide, instead of FADH2. 7. The first step of oxidation generates a trans-intermediate plus FADH2. The second step involves addition of water across the trans double bond to create an intermediate in with an OH on carbon 3 in the L configuration. The third step involves oxidation of the hydroxyl intermediate to a ketone on carbon 3. The last step involves cleaving off of an acetyl-CoA and production of a fatty acyl-CoA with two fewer carbons. 8. Oxidation of biologically occurring fatty acids with cis double bonds requires two additional enzymes compared to oxidation of saturated fatty acids. These enzymes are enoyl-CoA-isomerase and 2,4-dienoyl-CoA-reductase. 9. Enoyl-CoA-isomerase converts cis or trans bonds between carbons 3 and 4 to trans bonds between carbons 2 and 3. 10. 2,4-dienoyl-CoA reductase acts on intermediates that have double bonds between carbons 2-3 and 4-5. It uses NADPH to reduce the two double bonds to one double bond and the resulting double bond is placed in a cis configuration between carbons 3-4. 11. Oxidation of fatty acids with odd numbers of carbons yields a final product of propionyl-CoA, not acetyl-CoA. 12. Conversion of propionyl-CoA to succinyl-CoA requires three steps. The first is addition of a carboxyl-group to the middle carbon in the molecule. 13. Ketone bodies are produced by the body when glucose precursors are not available to make glucose. Examples of ketone bodies include acetoacetate and hydroxybutyrate. Diabetics have problems with glucose metabolism and may produce ketone bodies to provide energy to keep the brain alive. One can detect this by the smell of acetone on their breath. Fatty Acid Biosynthesis 1. The process occurs similarly to beta-oxidation, though in reverse. Important distinctions are noted below in a-f. a. Fatty acid synthesis up to palmitate occurs in the cytoplasm. b. Fatty acids are built using an acyl carrier protein (ACP),. c. NADPH is used to donate electrons in synthesis. d. A three carbon molecule, malonyl-ACP donates two carbons to the growing fatty acid chain - a carbon dioxide is lost in the process. e. Synthesis of fatty acids longer than 16 carbons occurs in endoplasmic reticulum or mitochondrion. f. In fatty acid biosynthesis, a D-hydroxyl intermediate is formed at carbon #3. 2. Acetyl-CoA carboxylase catalyzes the addition of a carboxyl group to acetyl-CoA to form malonyl-CoA. 3. The enzymes of fatty acid synthesis apart from acetyl-CoA carboxylase are contained in a complex known as fatty acid synthase. 4. Fatty acid synthase produces the saturated 16 carbon fatty acid known as palmitate.

A Fungal Disease Origin for 'Hearing Voices' (Schizophrenia)
This video describes how a common fungal infection, prenatal trauma, and the endoplasmic reticulum inside cells interact to cause the experience of 'voices'. Surprisingly, almost the entire human population has this problem, but most people can suppress the volume of their 'voices' adequately. Two approaches for treatment are discussed: a quick, one voice at a time treatment; or one that eliminates all voices simultaneously by using a psychoneuroimmunology technique that makes the client immune to the fungus. The video was created by Piotr Kawecki and narrated by Dr. McFetridge from the Institute for the Study of Peak States.

Cancer Cells Send Signals Boosting Survival and Drug Resistance in Other Cancer Cells
Presented By: Jeffrey James Rodvold, PhD - Postdoctoral Researcher, UCSD Speaker Biography: Jeffrey is an expert in tumor microenvironment biology. Currently a postdoctoral researcher, he completed his PhD in Biomedical Sciences at UC San Diego focused on the unfolded protein response (UPR) within the tumor microenvironment. His research involved elucidating how the tumor microenvironment becomes dysregulated within both the cancer cell and immune infiltrate compartments through the production of signaling molecules cancers cells producing during the UPR. He earned his BS in Bioengineering : (Biotechnology) from UC San Diego in 2010 where he performed research in the fields of biomaterials and stem cell mechanotransduction. Webinar: Cancer Cells Send Signals Boosting Survival and Drug Resistance in Other Cancer Cells Webinar Abstract: Successful tumor outgrowth requires the coordination of a variety of cell intrinsic and cell extrinsic signaling events. These events include those establishing a tumor microenvironment (TME) that both enables tumor cell survival and disables anti-tumor immunity. Recent reports demonstrate that these events require molecules produced by resident tumor cells. Tumor-borne signals within the tumor microenvironment propagate tumor cell fitness and immune hijacking. The endoplasmic reticulum (ER) stress is an adaptive response to a variety of TME insults, including hypoxia and nutrient deprivation, raising the possibility that ER stress could serve as a potential source of tumor cell fitness and immune dysregulation. To that end, we induced cancer cells of various origin to undergo ER stress and harvested the resulting conditioned medium (CM) to explore its effects on both recipient cancer cells and immune cells. Cell culture medium became an invaluable tool to our studies as it allowed us to recreate stimuli existent within the tumor microenvironment under controlled conditions. Our results revealed that the CM of cancer cells undergoing ER stress transmits ER stress to recipient cells. On the one hand, myeloid cells (macrophages and dendritic cells) treated with the CM of ER stressed cancer cells acquire a mixed pro-inflammatory and immune suppressive phenotype, which restrained T cell anti-tumor immunity and facilitated tumor growth in vivo. On the other hand, cancer cells treated with the CM of ER stressed cancer cells acquire cellular fitness to a variety of challenges including nutrient deprivation and chemotherapies. When implanted into immune competent hosts, ER stress experienced cancer cells grew at markedly faster rates than inexperienced ones. These findings support the existence of a novel mechanism used by tumor cells to restrain anti-tumor immunity while enhancing cellular fitness with the TME.

Role of PTP1B in the regulation of the immune system
Obesity is associated with insulin resistance, type 2 diabetes, cardiovascular disease, cancer and many other devastating diseases. Obesity is also a state of chronic inflammation and, as such, the cells in our immune system become overactive. Professor Mirela Delibegovic is studying proteins crucial in the on/off switches in our immune cells, called tyrosine phosphatases. Using the latest DNA sequencing technology, this research will improve our understanding of the immune system and allow development of specific therapies for different diseases.

O dobramento das proteínas pode ser afetado ainda por processos fisiológicos, tais como o acúmulo de grandes quantidades de proteínas imaturas no RE ocasionado por um excesso de nutrientes que estimulam a produção da insulina. Quando há excesso de proteínas localizadas no reticulo ocorre sobrecarga da capacidade de dobramento, condições essas que alteram a homeostase do RE e comprometem seu adequado funcionamento, gerando um estado conhecido como estresse do reticulo endoplasmático, que em resposta celular ao estresse, ativa um denominado mecanismo adaptativo a proteínas desdobradas chamada de Unfolded Protein Response, a UPR.
