A photosensitive element that occurs in both crystalline and amorphous types, is gotten mainly as a spin-off in copper refining, and is used particularly in glass, semiconductor devices, and alloys. [1]

The story starts in 2004

The story starts in 2004 at ThoughtWorks in Chicago, with Jason Huggins developing the Core mode as “JavaScriptTestRunner” for the testing of an internal Time and Expenses application (Python, Plone). Automatic screening of any applications is core to ThoughtWork’s style, provided the Agile leanings of this consultancy. He has help from Paul Gross and Jie Tina Wang. For them, this was a day task.

Jason started demoing the test tool to various associates. Numerous were thrilled about its immediate and intuitive visual feedback, along with its possible to grow as a reusable testing structure for other web applications.

Right after in 2004 fellow ThoughtWorker Paul Hammant saw the demonstration, and started discussions about the open sourcing of Selenium, in addition to defining a ‘driven’ mode of Selenium where you ‘d get to use Selenium over the wire from a language of your choice, that would navigate the ‘very same origin policy’. Other (then) associates, Aslak Hellesoy and Mike Melia, explore various ideas for the ‘server’ piece, including page rewriting to navigate the exact same origin policy. Paul wrote the initial server piece in Java, and Aslak and Obie Fernandez ported that the customer chauffeur to Ruby, setting the structure for motorists in yet more languages.

ThoughtWorkers in various offices around the world picked up Selenium for industrial tasks, and contributed back to Selenium from the lessons learned on these tasks. Mike Williams, Darrell Deboer, and Darren Cotterill all assisted with the increasing the capabilities and the toughness of it.

On the other hand, beyond ThoughtWorks …

At Bea, Dan Fabulich and Nelson Sproul came to the conclusion that the driver/server to internet browser architecture was not the most useful or versatile, so forked the motorist coder and crafted that into a standalone server that leveraged and bundled MortBay’s Jetty as a web-proxy. When the code was merged back it became called “Selenium Remote Control” and the old driven codeline and capability was retired.

Pat Lightbody became included at the same time, with a business concept that needed him to quit his day task (Jive Software application). The concept was “Hosted QA”, and it was ultimately moved into Gomez’s service line. Pat worked with Dan and Nelson making Selenium RC steady for big scale implementation. Pat had independently coded a grid for Hosted QA that took screenshots of web browsers in numerous states, and was looking after numerous consumers simultaneously. Jason had the very same hosted QA concept a year before, but did not stop his day task to do it.

In 2007 Dan moved to the quickly growing Redfin, which likewise part-time sponsors his time on Selenium, and encourages a speaking agenda. [2]

Why do individuals take selenium?

Selenium has attracted attention because of its antioxidant homes. Antioxidants secure cells from damage. Evidence that selenium supplements might minimize the chances of prostate cancer has been blended, however the majority of research studies recommend there is no real advantage. Selenium does not appear to impact the danger of colorectal or lung cancer. But beware: some studies recommend that selenium may increase the risk of non-melanoma skin cancer.

Among healthy people in the U.S., selenium deficiencies are unusual. But some health conditions– such as HIV, Crohn’s disease, and others– are related to low selenium levels. People who are fed intravenously are also at risk for low selenium. Medical professionals often recommend that people with these conditions utilize selenium supplements.

Selenium has actually likewise been studied for the treatment of dozens of conditions. They vary from asthma to arthritis to dandruff to infertility. However, the outcomes have actually been undetermined. [3]

Health Benefits of Selenium

Possibly Reliable:

1) Thyroid Disorders

Selenium is most concentrated in the thyroid and assists manage its function. Severe selenium deficiency may impair its function and is linked to various thyroid disorders.

Hashimoto’s Illness

Selenium supplementation can be beneficial for people with Hashimoto’s thyroiditis or autoimmune hypothyroidism. In a review of 4 scientific studies, selenium improved mood, general wellness, and thyroid peroxidase antibodies in individuals with Hashimoto’s. The direct advantages on thyroid structure and function were less clear, though.

Grave’s Disease

Graves’ illness (GD) is an autoimmune illness in which the thyroid ends up being bigger and overactive. In 38 selenium-deficient clients with Grave’s disease, Se supplementation significantly lowered thyroid hormonal agents.

However, it revealed no short-term advantages in another trial of 30 GD patients with regular selenium levels.

The advantages of Se supplements for Graves’ disease may be restricted to Se-deficient patients.

Other.

Some pregnant females experience mildly decreased thyroid function, also called subclinical hypothyroidism (increased TSH, regular T4).

In an analysis of over 300 pregnant females, lower selenium blood levels were linked to thyroid enlargement and damage. Selenium supplements helped bring back thyroid health, particularly after birth. Selenium was utilized in the form of Selenomethionine, a naturally-occurring selenium-bound amino acid.

In mice with autoimmune thyroiditis, selenium increased T-reg immune cells, which are vital for getting rid of the destructive autoimmune reaction. It likewise decreased blood levels of disease-related antibodies (thyroglobulin TgAb).

2) Viral Infections

Absence of selenium can set off the immune system and cause even safe virus infections to advance and become harmful. In the most severe cases, this can result in complete cardiac arrest (Keshan disease).

Adequate selenium consumption secures immune cells and help in producing antibodies. Lower selenium levels can increase damage (by means of oxidative stress) in healthy cells, reducing immune defense, activating viruses, and activating their faster department.

HIV infections can trigger selenium deficiency, while supplements may assist fight HIV and enhance results. In one trial of 18 HIV-positive individuals, selenium in combination with standard drugs enhanced the lifestyle. Selenium likewise blocked the replication of the infection in cellular and animal research studies.

Selenium levels may forecast the illness result in HIV-positive individuals. In one research study, selenium-deficient HIV clients were almost 20 times more likely to die from HIV than those with regular selenium levels.

In one study on kids, low selenium levels not only increased the likelihood of passing away from HIV but were also linked to faster dispersing of the disease.

3) Kashin-Beck Illness Prevention

Kashin-Beck illness (KBD) is an endemic disease of the joints and bones, mainly happening in particular China regions, particularly Tibet. Selenium shortage plays an important role, along with various environmental and hereditary elements.

According to a meta-analysis of 11 Chinese clinical trials with 2652 patients, adding Se-enriched salt to a diet plan decreases the odds of Kashin-Beck disease by 84% in healthy kids, compared to iodized salt.

However, Se supplementation didn’t enhance joint pain or mobility in 324 children with Kashin-Beck illness. The authors emphasized the function of iodine shortage in KBD.

4) Preeclampsia

Preeclampsia is identified by high blood pressure, swelling, and the presence of protein in the urine during pregnancy.

In a meta-analysis of 3 trials with 439 pregnant women, Se supplements (60-100 mcg daily for approximately 6 months) reduced the risk of preeclampsia by 72% compared to placebo. According to 13 observational studies (1,515 individuals), pregnant women with low Se levels have a greater danger of preeclampsia.

Insufficient Evidence:

No legitimate clinical evidence supports making use of selenium for any of the conditions in this area. Below is a summary of updated animal studies, cell-based research study, or low-quality medical trials which must stimulate additional investigation. However, you shouldn’t translate them as encouraging of any health benefit.

5) Brain Defense

The advantages of fish consumption are frequently attributed to polyunsaturated fats, omega-3s, however high amounts of selenium found in fish might be similarly essential. Selenium works in synergy with the fats, avoiding their breakdown and boosting their advantageous results on cognition.

In one study on 200 older people, fish consumption increased selenium blood levels more than omega-3 levels. According to the authors, better cognitive function in the elderly might depend straight on selenium [24]

Selenium is extremely essential for your brain health. Low selenium levels are connected to poor cognition, memory issues, and low neurotransmitter levels in the brain. Alzheimer’s clients had only 60% of the brain selenium levels of healthy people in one research study.

6) Cancer Avoidance

The function of selenium in cancer prevention is a hot subject of debate and the findings are clashing. Selenium supplements aren’t approved for cancer prevention or treatment.

Encouraging Research

Since the 70s, studies have been reporting that increased selenium consumption decreases cancer deaths and vice versa. In one study, the dietary consumption of selenium in 27 nations was linked to fewer deaths from cancer. In the US, deaths from cancer were much higher in low selenium counties, in which individuals are most likely to be deficient.

Early research studies of approximately 11,000 individuals reported that low selenium status is related to an increased cancer threat of cancer and death. The approximated risk ranged from 2 to six-fold and was at times just applicable to men.

Some current research studies support early findings. Slightly increased selenium consumption– still well below poisonous levels– was associated with a lower threat of colorectal and prostate cancer.

In 37 guys, a combination of Milk thistle (Silymarin) and selenium minimized LDL, swelling, and total cholesterol after prostate removal surgery, possibly avoiding prostate cancer relapse and progression.

Conflicting Research

A substantial limitation is that the majority of research studies of selenium consumption and cancer danger are observational. Observational research studies can make associations, but can’t attribute any causation.

There have been really few scientific trials using selenium as a restorative representative, which are needed to identify its impacts. Numerous other factors– consisting of lifestyle, genes, gender, and age, phase, and kind of cancer– will impact cancer outcomes and the preventive action of selenium.

In one clinical trial of over 1,000 people with a history of nonmelanoma skin cancer, 200 µg/ day of selenium (as selenium yeast) didn’t lower the possibilities of regression. But it did lower all-type cancer mortality by 50% and cancer rates by 37%. It particularly lowered the rates of prostate, colon, and lung cancer.

According to a meta-analysis of 15 clinical trials, Se supplements may decrease the risk of lung cancer in deficient patients but increase the danger in patients with typical Se levels.

Once again, the benefits of Se supplementation in fact came from fixing a deficiency.

Discouraging Research

Regardless of a number of promising clinical trials, the largest evaluation up-to-date concluded that there is no evidence to support increased selenium consumption through diet plan or supplements in preventing cancer in people. This evaluation consisted of 83 research studies and stressed those drawbacks of the readily available research studies.

Selenium supplements or increased dietary intake would certainly supply advantages to Se-deficient people. However considered that deficiency is quite rare, it would be best to inspect selenium blood levels before taking supplements. Whether selenium prevents cancer is still unidentified while taking in excessive selenium can only be hazardous.

More medical research is required, taking into account genetics, dietary status, and numerous types of selenium supplements.

7) Immune Action

Selenium deficiency impairs immune function. Accordingly, selenium supplementation stimulates the body immune system, even in individuals who are not deficient. Lymphocytes of individuals who supplemented with selenium (200 µg/ day) were more active and effective at ruining foreign invaders and growth cells.

Selenium might be more crucial for appropriate resistance than was previously realized. Triggered immune cells have actually an increased need for selenium and its amino-acid bound type (selenocysteine), according to current studies.

Helpful For Th2-Dominant People

Selenium supplements might help divert the immune response away from the Th2-type and promote the Th1-type, which protects against asthma, allergic reactions, viral infections and cancer.

More research studies are needed to examine the immune-stimulating homes of selenium.

8) Fertility and Reproductive Health

Balanced selenium levels are essential for reproductive health in both males and females. In guys, selenium is very important for producing sperm and testosterone.

In a study of 69 guys with fertility problems, selenium supplements mildly increased sperm motility however didn’t enhance sperm density. 11% of the men who took selenium attained paternity, compared to none in the placebo group.

However, Se supplements had no advantages on sperm count, motility, or quality in a similar trial of 33 clients.

In studies on male rats, selenium increased testosterone levels however only in rats who were selenium-deficient.

In ladies, sufficient selenium levels are specifically essential throughout early pregnancy. In one study, females who suffered from persistent miscarriages were more likely to have lower selenium blood levels. Selenium deficiency was also linked to an increased probability of miscarriages in animal studies.

9) Heart Health

Selenium might protect against heart disease, most likely by enhancing the antioxidant glutathione, lowering oxidative tension and avoiding platelet clumping.

Selenium deficiency ultimately triggers damaging, reactive substances to develop, making capillary less versatile and platelets more “sticky”. For example, in males with cardiovascular disease, low selenium might cause platelets to clump together and narrow capillary, potentially worsening heart health.

The medical results are still combined, though. In one research study, low selenium was connected to a 2- to three-fold boost in cardiovascular disease, while in another study guys with low selenium were at an increased danger of heart attacks or stroke. However other small research studies didn’t discover any clear link between heart disease danger and selenium levels.

In 668 senior Swedish people, supplements with selenium (200 μg) and coenzyme Q10 (200 mg) for four years considerably lowered the threat of cardiac arrest. It visited 50% in formerly Se-deficient clients and by 62% in clients with moderate Se levels.

Clients with high Se levels didn’t gain from supplementation, recommending once again that the benefits might be limited to Se-deficient individuals.

More research study must determine whether selenium supplementation protects versus heart disease and under which occasions.

10) Mood and Anxiety

Low selenium levels have been linked to anxiety, stress and anxiety, exhaustion, and mental confusion. In one research study of 50 people, selenium supplementation (100 mcg/day) over 5 weeks enhanced state of mind, energy levels, and reduced anxiety.

Selenium supplements over 8 weeks visibly enhanced depression and slightly minimized anxiety in a research study on elders residing in assisted living home.

Selenium Blood Test & & Typical Ranges

The margin between selenium deficiency, optimal and above-optimal levels and toxicity is really narrow. Knowing your selenium status can be useful in identifying potential health problems.

The most typical way to determine selenium status is using blood biomarkers that show selenium intake, which can consist of the following:.

  • Elemental selenium (normal variety: 70– 160 ng/mL)
  • glutathione peroxidase
  • Selenoprotein P, the main supplier of selenium to tissues

To increase longevity, fight swelling, and aid in cancer prevention, even higher blood levels have been investigated. A little above-optimal consumption may reduce the danger of lung, prostate and colorectal cancers, but the evidence is undetermined.

Aside from blood tests, long-term selenium status can additionally be assessed by measuring selenium concentrations in toenails and hair. [4]

16 Intriguing Selenium Facts

Selenium is a chemical component found in a wide range of items. Here are some fascinating facts about selenium:.

  • Selenium is a nonmetal. Like lots of nonmetals, it exhibits various colors and structures (allotropes) depending upon the conditions.
  • Brazil nuts are high in selenium, even if they are grown in soil that is not rich in the component. A single nut offers enough selenium to fulfill the day-to-day requirement for a human grownup.
  • English electrical engineer Willoughby Smith (1828– 1891) discovered that selenium responds to light (photoelectric impact), causing its usage as a light sensor in the 1870s. Scottish-born American creator Alexander Graham Bell (1847– 1922) made a selenium-based photophone in 1879.
  • The main use of selenium is to decolorize glass, to color glass red, and to make the pigment China Red. Other uses are in photocells, in laser printers and copy machines, in steels, and in semiconductors.
  • There are 6 natural isotopes of selenium. One is radioactive, while the other five are steady. However, the half-life of the unstable isotope is so long that it is basically steady. Another 23 unstable isotopes have actually been produced.
  • Some plants require high levels of selenium to endure, so the presence of those plants indicates the soil is rich in the component.
  • Liquid selenium exhibits extremely high surface area stress.

  • The aspect was included in the films “Ghostbusters” and “Development.” [5]

Chemical worth of selenium

Selenium is an aspect present in the periodic table of all the existing components found by human beings. The numerous chemical and essential properties of selenium are discussed below.

Selenium occupies the 34th element in the periodic table. This also indicates that the atomic number of selenium is 34.

Like every other element on the table of elements, selenium has an atomic sign, too, which is ‘Se.’ This atomic sign is utilized when expressing a chain reaction including selenium or among its compounds.

  • The atomic mass, or weight, of selenium is 78.96.
  • Selenium’s state at room temperature is solid.
  • The melting point of selenium is 428 F (220 C), and its boiling point is 1,264.64 F (684.8 C).
  • Selenium has many isotopes, however just six of them are referred to as steady isotopes.
  • Selenium is positioned right below sulfur, and both aspects share similar physical along with chemical homes.
  • There are many allotropes of selenium, but only three are popular. The first one is amorphous selenium, which exists in powder and vitreous or glassy types. While in the former, it is red in color, in the latter stage it is black.
  • Another allotrope of selenium is crystalline hexagonal selenium, which is considered to be the most steady allotropic type of selenium. This allotrope is metal gray.
  • The 3rd allotrope is crystalline monoclinic selenium, which exists in a crimson color.
  • Selenium is grouped as a chalcogen and is a non-metal.
  • It can be found individually in nature, however it is often present as a compound such as zinc selenide or selenium dioxide.
  • It is also a part of rare minerals like clausthalite.

  • Out of all the selenium compounds, hydrogen selenide is the most harmful one. It is present in gaseous type.
  • Taking selenium supplements when it is already present in high amounts in your natural diet plan can cause selenium poisoning.

Plants With High Amounts Of Selenium

Selenium’s natural abundance on earth can be found in lots of locations. Research has actually discovered that levels of selenium are high in seafood and some kinds of organ meat. It is even present in the water that individuals drink in some places.

If there is selenium present in the soil, it can affect the quantity of selenium in the food that grows in it. This is further affected by factors such as the pH of the soil.

Vegetables such as cauliflower, cabbage, and broccoli also have a high level of selenium existence.

Plants like Brazil nuts and garlic, when grown in soil that has a rich amount of selenium, can collect the mineral too.

Some grains and cereals like wheat can have a relatively high content of selenium too. [6]

Use of selenium supplements

Individuals can get selenium through multivitamins and other dietary supplements. These may consist of the mineral in various types, including selenomethionine and salt selenate.

The Dietary Guidelines for Americans, 2020– 2025Trusted Source encourage individuals to get their nutrients from food sources instead of supplements. Consuming a varied and healthful diet is more vital than concentrating on individual nutrients as the key to health.

When taking any supplement, it is essential to acquire it from a reputable source. In the United States, the Fda (FDA) does not keep an eye on supplements for quality, pureness, product packaging, or strength. [7]

Signs of Selenium Deficiency You Might Be Disregarding

Selenium Deficiency Sign: You’re losing your hair

Among the most crucial things on selenium’s to-do list: assist convert your T4 thyroid hormonal agent into the more active type called T3, discusses Small. If you run low, you might suffer from signs of hypothyroidism, among which is hair loss. “There can be numerous factors for loss of hair, so it’s your health professional’s job to know what to evaluate for,” states Small.

Selenium Shortage Sign: You’re so exhausted

Another typical hypothyroid sign: fatigue. This may be a result of poor selenium levels decreasing your thyroid. “We wish to knock out the apparent way of life elements prior to looking at selenium,” says Small. That may be guaranteeing that your diet has appropriate levels of carbs, protein, and fat, trying to find a vitamin D shortage, or analyzing iron levels. Then, make sure to follow these healthy practices for your thyroid.

Selenium Deficiency Symptom: You’re putting on weight

When you experience undesirable weight gain, you’ll wish to get to the origin. Once again, your thyroid’s thirst for selenium might contribute, and fixing that insufficiency can assist your thyroid get back online. Although Small very first take a look at diet when a client is gaining weight, she will think about screening selenium levels down the line. To learn why you’re loading on the pounds, think about these surprising reasons for weight gain.

Selenium Shortage Symptom: You’re not functioning at your finest

Selenium is required to form selenoproteins, states Little, including glutathione peroxidase: “It is among the body’s primary ways to take hazardous toxic substances and turn them into harmless by-products,” she states. “Deficiencies in this can lead to quite serious health consequences,” she keeps in mind.

Selenium Deficiency Sign: You may be at a higher risk for certain cancers

You’re most likely up for doing whatever you can to prevent cancer– and keeping optimum levels of selenium might reshuffle the deck in your favor. In a 2014 Cochrane Review, researchers evaluated 55 observational studies to look at the link between selenium and cancer. They found a 31 percent lower risk of cancer associated with higher selenium exposure, particularly with stomach, bladder, and prostate cancer. However other trials stopped working to show a gain from selenium. Without concrete proof, the authors conclude that supplements probably aren’t the response. Rather, concentrate on the foods you can eat that will supply a variety of health benefits, including selenium-rich foods like asparagus, broccoli, and mushrooms. And while you’re at it, you might want to avoid these 10 unexpected things that can trigger cancer.

Selenium Deficiency Symptom: You’re sick all the time

Initially, make sure you’re cleaning your hands routinely, you got the influenza shot, and you’re sleeping long enough and soundly (try these 13 tricks from sleep physicians). However you’re refraining from doing yourself any prefers if your selenium levels are low. “Without the ability to properly make glutathione peroxidase, your body immune system can’t operate appropriately, and you might find you’re sick more frequently,” says Small.

Selenium Deficiency Symptom: Your body is under a lot of stress

Selenium is a powerful disease-fighting antioxidant. “Oxidative stress causes damage to cells throughout your body. At any time you can safeguard your cells from oxidative stress is an advantage,” states Small. Discover go-to methods to simmer down in the moment, sleep enough to help your body recuperate, and eat well– including getting adequate selenium in your diet plan.

Selenium Shortage Sign: You have shortness of breath

Those selenoproteins have another important task: to protect your heart. A male who had Crohn’s disease recounted his case: He suffered from inflamed legs and shortness of breath and it was later found that he had a selenium shortage that triggered his heart failure. However the jury is still out on supplements: Although low selenium levels have actually been related to a higher threat of heart disease, experts hesitate to suggest taking selenium tablets. Rather, stick to a healthy, selenium-rich diet. [8]

Selenium negative effects

Get emergency situation medical aid if you have any of these indications of an allergy: hives; difficult breathing; swelling of your face, lips, tongue, or throat.

Long term use of high selenium dosages can cause unsafe negative effects. Stop taking selenium and call your physician at the same time if you have:.

  • nausea, vomiting;
  • absence of energy, feeling irritable or extremely worn out
  • hair loss, moderate rash, fragile or unpleasant fingernails, or white streaks on the nails;
  • tremors, feeling light-headed;
  • muscle tenderness;
  • flushing (heat, soreness, or tingly feeling);
  • metal taste, foul breath, strong body odor; or
  • easy bruising or bleeding. [9]

The quantity of medication that you take depends upon the strength of the medication. Also, the number of doses you take each day, the time permitted in between doses, and the length of time you take the medication depend upon the medical problem for which you are using the medication.

For selenium:.

For oral dosage kind (tablets):.

To prevent shortage, the quantity is based upon regular daily recommended consumption:.

  • Adult and teenage males– 40 to 70 micrograms (mcg) each day.
  • Grownup and teenage women– 45 to 55 mcg daily.
  • Pregnant women– 65 mcg per day.
  • Breast-feeding women– 75 mcg daily.
  • Children 7 to 10 years of age– 30 mcg daily.
  • Children 4 to 6 years of age– 20 mcg per day.
  • Children birth to 3 years of age– 10 to 20 mcg each day.

To deal with shortage:

Grownups, teenagers, and kids– Treatment dose is figured out by prescriber for each individual based upon seriousness of shortage.
