We have been waiting with bated breath for the results of Wayne State University’s study on the potential for us to influence our body’s response to cold exposure, and are excited to finally share them. The full study is published in the science journal NeuroImage and you can read the full synopsis below. For more great content visit: https://www.wimhofmethod.com/ ===== "Brain Over Body" - A study on the willful regulation of autonomic function during cold exposure The defence of body temperature against environmental thermal challenges is a core objective of homeostatic regulation governed by the autonomic nervous system. Autonomous mechanisms of thermoregulation are only weakly affected by top-down modulation, allowing only transient tolerance for extreme cold. There is however, anecdotal evidence of a unique set of individuals known for extreme cold tolerance. Here we present a case study of a 57-year old Dutch national, Wim Hof, the so-called “Iceman”, with the ability to withstand frequent prolonged periods of extreme cold exposure based on the practice of a self-developed technique involving a combination of forced breathing, cold exposure and meditation (collectively referred to as the Wim Hof Method, henceforth “WHM”). The relative contributions of the brain and the periphery that endow the Iceman with these capabilities is unknown. To investigate this, we conducted multi-modal imaging assessments of the brain and the periphery using a combination of fMRI and PET/CT imaging. Thermoregulatory defence was evoked by subjecting the Iceman (and a cohort of typical controls) to a fMRI paradigm designed to generate periods of mild hypothermia interspersed by periods of return to basal core body temperature. fMRI was acquired in two separate sessions: in a typical (passive) state and following the practice of WHM. In addition, the Iceman also underwent a whole body PET/CT imaging session using the tracers C11-hydroxyephedrine (HED) and 18F-fluorodeoxyglucose (FDG) during both thermoneutral and prolonged mild cold conditions. This acquisition allowed us to determine changes in sympathetic innervation (HED) and glucose consumption (FDG) in muscle and fat tissues in the absence of the WHM. fMRI analyses indicated that the WHM activates primary control centers for descending pain/cold stimuli modulation in the periaqueductal gray (PAG), possibly initiating a stress-induced analgesic response. In addition, the WHM also engages higher-order cortical areas (left anterior and right middle insula) that are uniquely associated with self-reflection, and which facilitate both internal focus and sustained attention in the presence of averse (e.g. cold) external stimuli. However, the activation of brown adipose tissue (BAT) was unremarkable. Finally, forceful respiration results in increased sympathetic innervation and glucose consumption in intercostal muscle, generating heat that dissipates to lung tissue and warms circulating blood in the pulmonary capillaries. Our results provide compelling evidence for the primacy of the brain (CNS) rather than the body (peripheral mechanisms) in mediating the Iceman's responses to cold exposure. They also suggest the compelling possibility that the WHM might allow practitioners to develop higher level of control over key components of the autonomous system, with implications for lifestyle interventions that might ameliorate multiple clinical syndromes.

If a plant has enough water, minerals and energy it will grow right? Well sort of… but there is more to it - like why do plants bend towards the light and not just grow straight? And how come the stem grows up but the roots grow down? It isn’t as if a plant has eyes to tell it where the sun is. Plants are packed full of hormones, sending messages around to its different parts. Where humans have the creatively named ‘growth hormone’, plants have hormones called auxins. Auxin is produced in the stem tips and roots, and controls the direction of growth in response to different stimuli including light and gravity. Having been made in the tips of the stems and roots, auxin is moved in solution by diffusion to older parts of the plant. In the stem, the auxin causes the cells to change in elasticity. More elastic cells absorb more water, and can grow longer. Strangely though, stems and roots respond differently to high concentrations of auxins. Whilst the stem cells grow more, the root cells actually grow less. So auxins make plants grow, but why do they bend towards the light? How do they know to do this when they don’t have eyes? The bending happens because the light hits the one side more and breaks down the auxins in that side of the stem. So then growth slows down on the ‘light’ side. The faster growth on the ‘dark’ side causes the shoots and leaves to turn towards the light - which is ideal for the plant for photosynthesis. Auxin is produced in the tips of growing shoots. If the tips are cut off, then no auxin can be produced and so no plant growth. If the tips are covered, whilst auxin is still produced, light cannot break it down and so phototropism cannot occur: the plant just grows straight up and does not bend towards the light. Auxins have the opposite effect on root cells. In roots, auxins cause less growth. The shaded side of roots contain more auxins, and so they grow less. This enables the ‘light’ side of the roots to grow more and bend away from the light. And if that wasn’t weird enough, we have opposites happening with auxins and gravity too. In a horizontal root, the bottom side contains more auxins and grows less, so the root bends downwards in the direction of gravity. So positive geotropism. But of course, the stem responds differently. In a horizontal stem, again the bottom side contains more auxins because it is less directly hit by sunlight. But because auxins cause growth in stems, the bottom side grows more causing the stem to bend upwards, against the direction of gravity. So negative geotropism. But I am giving auxins too much credit; they don’t work alone. They have a partner in crime; cytokinins. You don’t need to know anything about these hormones other than the fact that they work alongside auxins. There is another plant hormone that you do need to be aware of… Gibberellins. Once a seed germinates, the roots and shoots start to grow. But for this, the seed needs energy. Luckily, the seed releases a hormone called gibberellin which causes the starch in the seed to turn into sugars and provide the seed with energy to grow. As well as causing shoot growth, gibberellins can also stimulate flowering and fruits in some plants. And they also work with auxins to cause stem elongation.

Lesson on Bile Acid Synthesis Pathway: Classic and Alternative Pathways, Primary and Secondary Bile Acids and Bile Salts. Bile acids are produced from cholesterol in the liver. Primary bile acids are produced via the classic and alternative bile acid synthesis pathways. Primary bile acids can also be conjugated to amino acids like glycine and taurine, which aids in bile acids ability to emulsify fats. Furthermore, primary bile acids can be processed by bacterial enzymes to form secondary bile acids. Hey everyone. In this lesson, you will learn about bile acid synthesis via the classic and alternative pathways. You will also learn the chemical structural modifications of cholesterol that occur to produce a primary bile acid. Furthermore, you will also learn the differences between primary and secondary bile acids, and bile salts and why it is important that we conjugate amino acids to bile acids during synthesis. -------------------------------------------------------------------------------------------------------- Check out some of my other lessons.

Hypertension nursing NCLEX review about pathophysiology, treatment, nursing interventions, and pharmacology. Hypertension is the amount of resistance of blood pumping through the body/arteries. It affects organ systems of the body such as the cardiovascular, brain, kidneys, and eyes. A normal blood pressure is less than 120/80 (systolic blood pressure/diastolic pressure). Nursing interventions include assessing hypertension risk factors, obtaining blood pressure readings, evaluating medication compliance, and monitoring for side effects of pharmacological medications used for hypertension.

Glaucoma is a group of eye diseases in which the optic nerve is damaged leading to irreversible loss of vision. In most cases, this damage is due to an increased pressure within the eye. The eye produces a fluid called aqueous humor which is secreted by the ciliary body into the posterior chamber - a space between the iris and the lens. It then flows through the pupil into the anterior chamber between the iris and the cornea. From here, it drains through a sponge-like structure located at the base of the iris called the trabecular meshwork and leaves the eye. In a healthy eye, the rate of secretion balances the rate of drainage. In people with glaucoma, the drainage canal is partially or completely blocked. Fluid builds up in the chambers and this increases pressure within the eye. The pressure drives the lens back and presses on the vitreous body which in turn compresses and damages the blood vessels and nerve fibers running at the back of the eye. These damaged nerve fibers result in patches of vision loss, and if left untreated, may lead to total blindness. There are two main types of glaucoma: open-angle and angle-closure. Open-angle glaucoma , or chronic glaucoma, is caused by partial blockage of the drainage canal. The angle between the cornea and the iris is "open", meaning the entrance to the drain is clear, but the flow of aqueous humor is somewhat slow. The pressure builds up gradually in the eye over a long period of time. Symptoms appear gradually, starting from peripheral vision loss, and may go on unnoticed until the central vision is affected. Progression of glaucoma can be stopped with medical treatments, but part of vision that is already lost can not be restored. This is why it's very important to detect signs of glaucoma early with regular eye exams. Angle-closure glaucoma, or acute glaucoma, is caused by a sudden and complete blockage of aqueous humor drainage. The pressure within the eye rises rapidly and may lead to total vision loss quickly. Certain anatomical features of the eye such as narrow drainage angle, shallow anterior chamber, thin and droopy iris, make it easier to develop acute glaucoma. Typically, this happens when the pupil is dilated and the lens is stick to the back of the iris. This prevents the aqueous humor from flowing through the pupil into the anterior chamber. Accumulation of fluid in the posterior chamber presses on the iris causing it to bulge outward and block the drainage angle completely. Acute angle-closure glaucoma is a medical emergency and requires immediate attention.

The body’s blood pH is strictly regulated within a narrow range between 7.35 and 7.45. This is because even a minor change in acidity may have devastating effects on protein stability and biochemical processes. Normal cellular metabolism constantly produces and excretes carbon dioxide into the blood. Carbon dioxide combines with water to make carbonic acid which dissociates into hydrogen ions and bicarbonate. This equilibrium is central to understand acid-base regulation. CONTINUED carbon dioxide production by all cells of the body drives the equilibrium to the right to generate more hydrogen ions. Because pH is basically a function of hydrogen ion concentration, more hydrogen means higher acidity and lower pH. Normal metabolism, therefore, constantly makes the blood more acidic. The body must react to keep the blood pH within the normal limits. This is achieved by 2 mechanisms: - Elimination of carbon dioxide through exhalation. The amount of carbon dioxide exhaled by the lungs is regulated in response to changes in acidity. A decrease in pH is sensed by central or arterial chemoreceptors and leads to deeper, faster breathing; more carbon dioxide is exhaled, less hydrogen is made, blood acidity decreases and blood pH returns to normal. Pulmonary regulation is fast, usually effective within minutes to hours. - Excretion of hydrogen ions and reabsorption of bicarbonate through the kidneys. The kidneys control blood pH by adjusting the amount of excreted acids and reabsorbed bicarbonate. Renal regulation is slower; it usually takes days to respond to pH disturbances. Pathologic changes may cause acid-base disturbances. Acidosis refers to a process that causes increased acidity, while alkalosis refers to one that causes increased alkalinity. It’s not uncommon for a patient to have several processes going on at once, some of them in opposite directions. The resulting plasma pH may be normal; too acidic, called acidemia; or too basic, called alkalemia. Acidosis may result from inadequate function of the lungs which causes arterial carbon dioxide to accumulate. This is RESPIRATORY acidosis. On the other hand, METABOLIC acidosis may result from excessive production of metabolic acids, decreased ability of the kidneys to excrete acids, ingestion of acids, or loss of alkali. Metabolic acidosis is characterized by primary decrease in plasma bicarbonate.

Today, Craig is going to dive into the controversy of monetary and fiscal policy. Monetary and fiscal policy are ways the government, and most notably the Federal Reserve, influences the economy - for better or for worse. So we’re going to start by looking at monetary policy, and specifically how the Federal Reserve uses interests rates as a means of controlling (or at least attempting to control) inflation. We’ll then move onto fiscal policy - that is the government’s use of taxation to raise and spend money. It’s all, well, pretty controversial, but as it seems Americans hate taxes the most, monetary policy is most often used - meaning that the Federal Reserve plays a hugely significant role in steering the U.S. economy.

Your cells have to divide when you're growing, to heal wounds, and to replace dead cells. But how do cells know when to divide and when not to divide? We can't have cells just growing willy-nilly! That's what cancer is, and that's bad. Luckily, cells obey something called the cell cycle, which is regulated by a variety of signaling molecules, which tell the cell when to divide and when to chill out. Let's look at the phases of this cycle and some of its regulatory mechanisms now.

How to prime IV tubing line (primary infusion) and how to spike a IV bag for nursing. The purpose of spiking an IV bag and priming IV tubing is to administer IV therapy to a patient by allowing the fluid from the bag to transfuse into the patient's blood stream. As the nurse, you will be doing this several times per day. It is standard nursing care because during a patient's hospitalization they will at some point receive IV fluids, medications, blood products, or fat emulsions. What does spiking the IV bag mean? It means you will be penetrating the IV bag with the spike of the IV tubing so the contents in the bag can flow into the IV tubing and then into the patient's blood. What does priming the IV tubing mean? It means you will be allowing the solution in the bag to flow through the tubing to remove any air in the line. It is very important to remove any air or bubbles from the tubing before infusion so an air embolism can be avoided. When you perform this nursing skill, it is important to remember to label the IV tubing when the IV therapy was initiated, because it expires. The CDC recommends changing IV tubing that is used continuously and not used for blood, blood products, or fat emulsion (TPN, Lipids) every 96 hours. It is very important to follow your hospital's protocol which are based on the CDC's recommendations. Some hospital require you change IV tubing every 72 hours. In addition, if the IV tubing is used for the administration of blood, blood products, or fat emulsions it should be changed every 24 hours. Again, follow your hospital's protocols.

Course materials at http://oregonstate.edu/instruct/bb450 Lecture Highlights Allostery/Regulation I 1. A manmade artificial substrate, known as PALA, binds to ATCase and inhibits the enzyme, but interestingly locks it in the R state. Though the enzyme can't catalyze a reaction when bound to PALA, it is clear that its form changes, again indicating that enzymes are changed by the binding of substrate and that T and R states exist. 2. Protein kinase A is an enzyme involved in covalent modification of enzymes. Like all kinases, it catalyzes the addition of a phosphate to a molecule. Since it is a protein kinase, the molecules it attaches a phosphate to are protein molecules. 3. Phosphates get attached to hydroxyl side chains in proteins. Protein kinase A attaches phosphate to serine or threonine. Other protein kinases can attach phosphate to tyrosine side chains. 4. Protein kinase A is controlled by allosteric means. It is composed of two regulatory subunits and two catalytic subunits. The overall complex is called R2C2. When the catalytic subunits are bound to the regulatory subunits, they cannot catalyze reactions. However, when the molecule cAMP binds to the regulatory subunits, the catalytic subunits are released and are thus active. When active, they covalently modify proteins by adding phosphates. 5. Zymogens are enzymes that are synthesized in an inactive form whose activation requires covalent modification, usually proteolytic cleavage. Examples include digestive enzymes, such as trypsin, chymotrypsin, elastase, and carboxypeptidase whose enzymatic activity might be harmful to the tissue where they are being made. 6. Trypsin is the primary activator of an entire class of proteolytic enzymes. Improper activation of trypsin in or close to the pancreas can lead to pancreatitis, which arises when the proteases attack proteins in the pancreas. 7. Activation of chymotrypsinogen to chymotrypsin, for example, requires trypsin. Trypsin makes an initial cleavage beween amino acids 15 and 16. A disulfide bond keeps the two pieces from coming completely apart, however. This creates an intermediately active form of chymotrypsin called pi-chymotrypsin. This form cleaves itself to remove two dipeptides and this results in full chymotrypsin activity. The three polypeptide pieces are held together by disulfide bonds. Note that three very minor changes in the chymotrypsinogen zymogen have converted a completely inactive enzyme to a fully active one. 8. Alpha-one-antitrypsin is an inhibitor of many proteases, including trypsin and elastase. Normally alpha-one-antitrypsin binds to elastase and prevents it from damaging tissue. People deficient in the factor have proteins in their alveolar walls of the lung (and other connective tissue proteins) destroyed, ultimately resulting in emphysema. Smoke from cigarettes will react with HEALTHY alpha-one-antitrypsin, causing a methionine residue to be oxidized. This oxidation, in turn, prevents alpha-one-antitrypsin from binding to elastase, allowing elastase to damage alveolar tissue and eventually cause emphysema. 9. Blood clotting is a process that is also tightly controlled by zymogens. The process is a cascade of catalytic events in which one enzyme activates another, which in turn activates hundreds/thousands, which in turn activate millions. Cascades are great for amplifying a signal. 10. Two pathways activate the clotting process, the intrinsic pathway and the extrinsic pathway. Ultimately these cascades lead to the conversion of prothrombin (zymogen) to thrombin (active enzyme). Thrombin, in turn, converts fibrinogen (zymogen) to fibrin (mesh former as a result of polymerization).

Synopsis: In a rare unanimous, bipartisan vote, the House passed a resolution calling for the Attorney General’s release of the Mueller report to the public. The Special Counsel regulations require Mueller to submit his report to the AG, with further disclosure coming at the AG’s discretion.
