VITAMINS: The Micronutrients in Our Body !

Vitamins

The essential macronutrients are water, proteins, carbohydrates, fats, vitamins, and minerals.

In developed countries, vitamin deficiencies result mainly from poverty, food fads, drugs, or alcoholism. Vitamin toxicity (hypervitaminosis) usually results from taking megadoses of Vitamin A, D, B6, or niacin. In general, excess amounts of water-soluble vitamins are excreted via the Kidneys.

Vitamins may be Fat soluble (vitamins A, D, E, and K) or Water soluble (B vitamins and vitamin C). The B vitamins include biotin, Folate, niacin, pantothenic acid, riboflavin, thiamine, pyridoxine, and B12. After digestion and absorption, which circulatory system carries fat and fat-soluble vitamins?

“Vitamins are the essential nutrients that our body needs in small amounts. More specifically, an organic compound is defined as a vitamin when an organism requires it, but not synthesized by that organism in the required amounts (or at all). There are thirteen recognized vitamins.”

Vegans may develop vitamin B12 deficiency unless they consume yeast extracts or Asian style fermented foods. Strictly, vegetarian diets also tend to be low in calcium, iron, and zinc.

Human Microbiome and its Association With Health and Diseases

Human microbiota are distinct communities of microorganisms that resides at different body niches. Exploration of the human microbiome has become a reality due to the availability of powerful metagenomics and metatranscriptomic analysis technologies. Recent advances in sequencing and bioinformatics over the past decade help provide a deep insight into the nature of the host-microbial interactions and identification of potential deriver genes and pathways associated with human health, well-being, and predisposition to different diseases. In the present review, we outline recent studies devoted to elucidate the possible link between the microbiota and various type of diseases. The present review also highlights the potential utilization of microbiota as a potential therapeutic option to treat a wide array of human diseases.

Humans are viewed as composites of human and microbial cells. Human microbiota are complex and dynamic microbial communities composed mainly of bacteria, but also includes protozoa, archaea, viruses, and fungi that resides in and on different body niches such as oral cavity, throat, esophagus, stomach, colon, urogenital tract, respiratory tract, and skin. The number of microbial cells inhabiting human body is estimated to exceed the H.sapiens cells by 10-fold and estimated at 350 trillion microbial cells.

Herpes gladiatorum: Facts, Symptoms, Causes, Risk Factors, Diagnosis, Treatments, Prevention and Outlook.

Clinical Issues

Herpes gladiatorum is an infection caused by herpes simplex virus type 1, a virus similar to that which causes cold sores. It is common among those who engage in high-contact sports, such as wrestling, and is also known as mat herpes. Those infected with herpes will carry the virus with them for life as there is no cure.

There will be periods where the virus is inactive and no symptoms are present, and times where it is active and causes various symptoms and flare-ups.

When the virus is active, the person carrying it is infectious and can spread herpes gladiatorum to others. The virus can be transmitted by skin-to-skin contact and is easily passed from one person to the next.

In this article, we examine the symptoms of herpes gladiatorum and the parts of the body that can be affected. We also take a look at diagnosis, treatment, and prevention of the condition.

Cutting Calories Won’t Help You Lose Weight, Why ?

So, you’re looking to shed a pound or two. Time to cut back on those pesky calories, right?

Not so fast. According to Michelle Adams-Arent, a sports nutrition consultant and the Director of Science and Education for Metabolic Precision, reducing your food intake might not work like you originally thought. In fact, it might actually backfire.

'Your body is built for survival,' Adams-Arent told Business Insider. 'It doesn’t care what you want to look like.'

The minute you start cutting back on your caloric consumption, your body goes into full-on starvation mode. Translation? Your metabolic rate will actually decrease as your body tries to preserve what little nutrition it has. A lower metabolism means fewer calories burned. What’s more, research even shows burning more calories than you consume over a long period of time can increase your body fat. Not exactly the outcome you were hoping for.

Pneumonitis: Symptoms, Causes, and Treatments.

Pneumonitis is a disorder where a person has an allergic reaction in their lungs caused by certain inhaled substances. The condition is also referred to as hypersensitivity pneumonitis.

The reaction they have to these substances can cause air sacs in one or both lungs to become inflamed. If untreated, the condition can cause long-term damage to the lungs. However, pneumonitis can be completely reversed if action is taken quickly. 

In this article, we take a look at the symptoms, causes, and treatments of pneumonitis. We also examine the differences between the condition and the more familiar pneumonia.

Symptoms of pneumonitis include shortness of breath, rattling sounds
in the lungs, and coughing.

Heterogeneity in Tuberculosis.

Infection with Mycobacterium tuberculosis, the causative agent of tuberculosis (TB), results in a range of clinical presentations in humans. Most infections manifest as a clinically asymptomatic, contained state that is termed latent TB infection (LTBI); a smaller subset of infected individuals present with symptomatic, active TB. Within these two seemingly binary states, there is a spectrum of host outcomes that have varying symptoms, microbiologies, immune responses and pathologies. Recently, it has become apparent that there is diversity of infection even within a single individual. A good understanding of the heterogeneity that is intrinsic to TB — at both the population level and the individual level — is crucial to inform the development of intervention strategies that account for and target the unique, complex and independent nature of the local host–pathogen interactions that occur in this infection. In this Review, we draw on model systems and human data to discuss multiple facets of TB biology and their relationship to the overall heterogeneity observed in the human disease.

Researchers are only beginning to understand the roles of the hundreds of proteins involved in reading, writing, and erasing the epigenome. One of the epigenetic regulators, SP140, which is mutated in a number autoimmune disorders, including Crohn’s disease and multiple sclerosis, is also essential to macrophage function and intestinal homeostasis in both humans and mice, scientists reported today (March 3) in Science Immunology.

“Many immune-mediated disorders are driven by a combination of genetic susceptibility as well as environmental influences [so] epigenetics is a suitable critical juncture between those two aspects of the disease,” said coauthor Kate Jeffrey, a researcher investigating the epigenetic control of innate immunity at Massachusetts General Hospital.

What It Means When You Dream About Being Naked In Public

You’re at the office and everything is normal... Until you get up during a meeting to give a presentation and you realize you are totally naked. 

It’s a dream many people have had in some iteration. But experts still aren’t entirely sure what it means.

Most psychologists agree it probably doesn’t represent a literal desire to be naked in public, but more likely is related to being embarrassed about something about yourself that other people don’t know about you.

Other psychologists have suggested this type of dream comes from harboring feels of guilt or inferiority ― or may be triggered by feeling neglected or deprived of attention in the past.

Of course some people think it means nothing at all. But neuroscientists and psychologists are convinced that, apart from meaning, dreams serve an important role in maintaining our mental and emotional health.

Decades of research suggest that dreams help us make memories, solve the problems we struggle with in our waking hours and process emotions ― even unpleasant ones where you accidentally expose yourself to everyone at work.

How Does Alcohol Affect My Blood Sugar Levels?

It is not uncommon to enjoy a glass of wine with dinner or to have drinks after work with friends. Alcohol consumption is very prevalent in the United States.

According to the National Institute on Alcohol Abuse and Alcoholism, in 2014:

• 87.6 percent of people age 18 and older reported drinking alcohol at some point in their lifetime
• 71 percent reported drinking in the past year
• 56.9 percent reported drinking in the past month

For many people, a glass of alcohol here and there does not pose a problem. For those with certain health conditions such as diabetes, however, alcohol can affect blood sugar levels and pose a health risk. It is important for them to understand what alcohol is and how it affects blood sugar levels.

Take This Vitamin And You Will NEVER Get Another Bite From A Mosquito Again!

Ah… summer. Longer days, sunny skies, sandy beaches… and mosquitoes. Lots and lots of mosquitoes.

For some, this isn’t too big of a deal, as mosquito repellent has been on the market since 1956.

But, if you’re like me at all and you not only want to stop smelling like the burnt remains of a chemical plant after using repellent, but also are scared of the adverse effects of DEET in sprays and are more prone to getting bit (seriously though, mosquitoes seemed to love me and only me at parties), then taking Vitamin B1 could be your saving grace.

Vitamin B1 (also known as thiamine) is an essential vitamin your body needs. It can be found in foods such as yeast, oatmeal, brown rice, asparagus, kale, liver and eggs and is important in fighting stress and boosting immunity.

Why Cockroach Milk Is the New Health Obsession

Health freaks will go to extreme lengths in the name of nutrients (and staying one step ahead of the trend), but I'm not afraid to say it: The latest "superfood" is just plain gross.

Taking stomach-churning to a whole new level is cockroach milk, which is comprised of the nutrient-rich milk crystals found inside the Pacific Beetle cockroach. This species uses said protein crystals as food for cockroach infants, but new research suggests that it could be beneficial to humans, too, as it's one of the most nourishing and highly caloric substances on the planet. It boasts four times as much protein as cow's milk, but also contains essential amino acids that promote cell growth, lipids that keep our bodies healthy, and sugars that fuel energy.

New Understanding Of Pulmonary Hypertension Leads To Promising Drug Targets

A groundbreaking new study led by researchers from the University of Pittsburgh and UPMC has identified a new group of compounds that could have robust effects in treating pulmonary hypertension (PH), an enigmatic but sometimes fatal disease of the blood vessels of the lungs that currently has no cure. The findings, which were published today in the Journal of Clinical Investigation, highlight the use of these drugs to alter vessel stiffness and its downstream control of metabolism, a link previously unknown for people suffering from the progressive disease.

“If we aim to cure this disease, the next set of medications and treatments should be those that target the origin at the molecular level,” said Stephen Y. Chan, M.D., Ph.D., director of the UPMC Center for Pulmonary Vascular Biology and Medicine at the Vascular Medicine Institute at Pitt, and senior author of the study. “As a community, we are struggling right now to understand those origins of PH, and this study aimed to address that untapped need.”

Liver Cancer Risk Influenced By Blood Selenium Levels

The risk of developing liver cancer may be significantly higher for people who have low levels of the nutrient selenium in their blood, suggests a new study published in the American Journal of Clinical Nutrition.

Selenium is a trace mineral present in soil, animal products, and plant-based foods, including seafood, Brazil nuts, organ meats, milk, and eggs.

The selenium content of food varies greatly, as it depends on how much of the element is in the plants animals consume, as well as how much is in the soil in which plants grow.

According to the National Institutes of Health (NIH), selenium is essential for human health, with beneficial roles for reproduction, the immune system, and DNA synthesis.

Studies have also shown that selenium has antioxidant properties, meaning it can protect against oxidative stress - the process by which uncharged molecules called free radicals damage cells.

1. FATIGUE

Fatigue is a common symptom in many types of cancer, including breast cancer. The thing is this type of fatigue cannot be alleviated by sleep or rest. Cancer-related fatigue is not caused by physical strain and is often accompanied by other symptoms such as pain, sleep disturbance and depression. This fatigue is caused by an imbalance of chemicals in the body the cancer creates, according to scientists.

The Common Cold and That Dreaded Flu Virus

Here it is again, the cold and flu season when we all head indoors to share our sneezes and viruses. It’s time to get serious about preventing illness, and that means caring for our personal air filter: the nose.

Viruses are the worst seasonal offenders, and colds are the most common virus we pass around. But the influenza virus is so much worse than a cold. Most folks do not really understand the difference between these two illnesses, yet the difference can be deadly.

Influenza, commonly called “the flu,” is caused by the influenza virus. This is a specific respiratory virus quite different than the cold virus. The entire respiratory tract—including the nose, throat, and lungs—becomes infected. The illness is severe and can be life-threatening; children, the elderly, and those who have underlying medical conditions are at greatest risk for complications.
