Selenium

A photosensitive component that occurs in both crystalline and amorphous forms, is gotten chiefly as a by-product in copper refining, and is used especially in glass, semiconductor devices, and alloys. [1]

The story begins in 2004

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

Jason began demoing the test tool to various colleagues. Lots of were excited about its immediate and intuitive visual feedback, as well as its prospective to grow as a multiple-use screening structure for other web applications.

Soon after in 2004 fellow ThoughtWorker Paul Hammant saw the demonstration, and started conversations about the open sourcing of Selenium, as well as specifying 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 ‘same origin policy’. Other (then) coworkers, Aslak Hellesoy and Mike Melia, experimented with different ideas for the ‘server’ piece, including page rewording to navigate the exact same origin policy. Paul composed the initial server piece in Java, and Aslak and Obie Fernandez ported that the client chauffeur to Ruby, setting the foundation for motorists in yet more languages.

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

On the other hand, beyond ThoughtWorks …

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

Pat Lightbody ended up being involved at the same time, with an industrial concept that required him to quit his day job (Jive Software). The idea was “Hosted QA”, and it was eventually moved into Gomez’s service line. Pat dealt with Dan and Nelson making Selenium RC stable for big scale implementation. Pat had actually privately coded a grid for Hosted QA that took screenshots of web browsers in different states, and was looking after several customers concurrently. Jason had actually the same hosted QA concept a year before, however did not stop his day task to do it.

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

Why do people take selenium?

Selenium has attracted attention because of its antioxidant residential or commercial properties. Anti-oxidants secure cells from damage. Evidence that selenium supplements may lower the chances of prostate cancer has actually been blended, however most studies suggest there is no genuine advantage. Selenium does not appear to affect the risk of colorectal or lung cancer. However beware: some research studies suggest that selenium might increase the threat of non-melanoma skin cancer.

Among healthy individuals in the U.S., selenium deficiencies are unusual. But some health conditions– such as HIV, Crohn’s disease, and others– are associated with low selenium levels. Individuals who are fed intravenously are likewise at risk for low selenium. Physicians in some cases suggest that individuals with these conditions utilize selenium supplements.

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

Health Advantages of Selenium

Perhaps Effective:

1) Thyroid Conditions

Selenium is most concentrated in the thyroid and helps regulate its function. Extreme selenium shortage may hinder its function and is linked to different thyroid conditions.

Hashimoto’s Disease

Selenium supplementation can be useful for people with Hashimoto’s thyroiditis or autoimmune hypothyroidism. In an evaluation of 4 scientific research studies, selenium enhanced state of mind, basic well-being, and thyroid peroxidase antibodies in people with Hashimoto’s. The direct benefits on thyroid structure and function were less clear, though.

Tomb’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 Tomb’s illness, Se supplements significantly reduced thyroid hormonal agents.

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

The advantages of Se supplementation for Graves’ illness might be restricted to Se-deficient patients.

Other.

Some pregnant women experience slightly minimized thyroid function, also called subclinical hypothyroidism (increased TSH, typical T4).

In an analysis of over 300 pregnant women, lower selenium blood levels were connected to thyroid enlargement and damage. Selenium supplements assisted restore thyroid health, specifically after birth. Selenium was used 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 essential for getting rid of the devastating autoimmune action. It also decreased blood levels of disease-related antibodies (thyroglobulin TgAb).

2) Viral Infections

Lack of selenium can trigger the immune system and trigger even safe virus infections to advance and become dangerous. In the most extreme cases, this can result in complete cardiac arrest (Keshan illness).

Adequate selenium consumption protects immune cells and help in producing antibodies. Lower selenium levels can increase damage (through oxidative tension) in healthy cells, minimizing immune defense, triggering viruses, and triggering their faster department.

HIV infections can set off selenium shortage, while supplementation may assist battle HIV and improve results. In one trial of 18 HIV-positive individuals, selenium in mix with standard drugs improved the lifestyle. Selenium likewise blocked the duplication of the infection in cellular and animal studies.

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

In one study on kids, low selenium levels not just increased the possibility of passing away from HIV however were also connected to faster spreading of the illness.

3) Kashin-Beck Illness Avoidance

Kashin-Beck disease (KBD) is an endemic disease of the joints and bones, primarily taking place in certain China areas, especially Tibet. Selenium deficiency plays an important role, along with different ecological and genetic 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 illness by 84% in healthy children, compared with iodized salt.

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

4) Preeclampsia

Preeclampsia is defined 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 ladies, Se supplements (60-100 mcg daily for approximately 6 months) lowered the danger of preeclampsia by 72% compared with placebo. According to 13 observational research studies (1,515 participants), pregnant women with low Se levels have a greater risk of preeclampsia.

Insufficient Evidence:

No legitimate scientific proof supports using selenium for any of the conditions in this area. Below is a summary of updated animal studies, cell-based research, or low-quality clinical trials which ought to trigger additional examination. However, you shouldn’t analyze them as supportive of any health advantage.

5) Brain Security

The advantages of fish consumption are frequently credited to polyunsaturated fats, omega-3s, however high quantities of selenium discovered in fish may be similarly crucial. Selenium works in synergy with the fatty acids, avoiding their breakdown and enhancing their beneficial results on cognition.

In one study on 200 older people, fish intake increased selenium blood levels more than omega-3 levels. According to the authors, better cognitive function in the senior may depend directly on selenium [24]

Selenium is very crucial for your brain health. Low selenium levels are linked to bad cognition, memory problems, and low neurotransmitter levels in the brain. Alzheimer’s clients had only 60% of the brain selenium levels of healthy individuals in one research study.

6) Cancer Avoidance

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

Supportive Research study

Since the 70s, research studies have actually been reporting that increased selenium consumption reduces cancer deaths and vice versa. In one research study, the dietary consumption of selenium in 27 countries was connected to less deaths from cancer. In the US, deaths from cancer were much greater in low selenium counties, in which people are most likely to be deficient.

Early studies of as much as 11,000 individuals reported that low selenium status is related to an increased cancer risk of cancer and death. The estimated danger varied from 2 to six-fold and was at times just appropriate to males.

Some current studies support early findings. A little increased selenium intake– still well listed below toxic levels– was related to a lower threat of colorectal and prostate cancer.

In 37 males, a mix of Milk thistle (Silymarin) and selenium lowered LDL, swelling, and overall cholesterol after prostate elimination surgery, possibly preventing prostate cancer regression and progression.

Conflicting Research

A considerable restriction is that the majority of research studies of selenium intake and cancer threat are observational. Observational studies can make associations, but can’t attribute any causation.

There have actually been extremely couple of scientific trials utilizing selenium as a healing representative, which are needed to determine its results. Numerous other factors– consisting of way of life, genes, gender, and age, stage, and type of cancer– will affect cancer results and the preventive action of selenium.

In one scientific trial of over 1,000 individuals with a history of nonmelanoma skin cancer, 200 µg/ day of selenium (as selenium yeast) didn’t lower the possibilities of relapse. But it did lower all-type cancer death by 50% and cancer rates by 37%. It specifically decreased the rates of prostate, colon, and lung cancer.

According to a meta-analysis of 15 scientific trials, Se supplementation may reduce the danger of lung cancer in deficient clients however increase the risk in clients with normal Se levels.

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

Discouraging Research study

In spite of a couple of promising clinical trials, the biggest evaluation current concluded that there is no evidence to support increased selenium consumption through diet plan or supplements in preventing cancer in people. This evaluation included 83 research studies and stressed those disadvantages of the readily available studies.

Selenium supplements or increased dietary consumption would unquestionably supply advantages to Se-deficient people. But considered that shortage is rather unusual, it would be best to check selenium blood levels before taking supplements. Whether or not selenium prevents cancer is still unknown while taking in excessive selenium can only be harmful.

More medical research study is required, considering genetics, dietary status, and numerous forms of selenium supplements.

7) Immune Response

Selenium shortage hinders immune function. Appropriately, selenium supplementation stimulates the body immune system, even in individuals who are not lacking. Lymphocytes of people who supplemented with selenium (200 µg/ day) were more active and effective at damaging foreign intruders and growth cells.

Selenium might be more crucial for appropriate immunity than was previously realized. Activated immune cells have actually an increased requirement for selenium and its amino-acid bound type (selenocysteine), according to recent research studies.

Great For Th2-Dominant Individuals

Selenium supplementation may assist divert the immune reaction far from the Th2-type and promote the Th1-type, which secures versus asthma, allergic reactions, viral infections and cancer.

More studies are needed to evaluate the immune-stimulating residential or commercial properties of selenium.

8) Fertility and Reproductive Health

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

In a research study of 69 males with fertility concerns, selenium supplements mildly increased sperm motility but didn’t enhance sperm density. 11% of the men who took selenium achieved paternity, compared to none in the placebo group.

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

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

In females, adequate selenium levels are especially important during early pregnancy. In one research study, ladies who experienced recurrent miscarriages were most likely to have lower selenium blood levels. Selenium deficiency was also linked to an increased possibility of miscarriages in animal research studies.

9) Heart Health

Selenium may safeguard against heart disease, probably by increasing the antioxidant glutathione, decreasing oxidative stress and preventing platelet clumping.

Selenium deficiency ultimately triggers harmful, reactive compounds to develop, making capillary less flexible and platelets more “sticky”. For example, in men with cardiovascular disease, low selenium may cause platelets to clump together and narrow blood vessels, possibly getting worse heart health.

The medical outcomes are still mixed, though. In one research study, low selenium was linked to a 2- to three-fold increase in heart problem, while in another research study men with low selenium were at an increased risk of heart attacks or stroke. However other little research studies didn’t discover any clear link between heart problem risk and selenium levels.

In 668 elderly Swedish individuals, supplements with selenium (200 μg) and coenzyme Q10 (200 mg) for four years significantly decreased the risk of heart failure. It stopped by 50% in previously Se-deficient patients and by 62% in clients with moderate Se levels.

Patients with high Se levels didn’t take advantage of supplementation, suggesting once again that the advantages might be limited to Se-deficient people.

Additional research study should determine whether selenium supplementation safeguards versus heart problem and under which occasions.

10) Mood and Stress And Anxiety

Low selenium levels have actually 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 improved state of mind, energy levels, and reduced anxiety.

Selenium supplements over 8 weeks significantly improved depression and mildly reduced stress and anxiety in a research study on senior citizens living in assisted living home.

Selenium Blood Test & & Typical Varieties

The margin in between selenium shortage, ideal and above-optimal levels and toxicity is extremely narrow. Knowing your selenium status can be useful in identifying prospective illness.

The most typical method to measure selenium status is using blood biomarkers that reflect selenium consumption, which can include the following:.

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

To increase durability, fight swelling, and help in cancer prevention, even higher blood levels have actually been researched. Slightly above-optimal consumption might decrease the threat of lung, prostate and colorectal cancers, however the proof is undetermined.

Aside from blood tests, long-lasting selenium status can additionally be examined by determining selenium concentrations in toe nails and hair. [4]

16 Fascinating Selenium Realities

Selenium is a chemical component discovered in a wide range of products. Here are some fascinating truths about selenium:.

  • Selenium gets its name from the Greek word “selene,” which indicates “moon.” Selene was the Greek goddess of the moon.

  • Selenium was found jointly in 1817 by Swedish chemists Jöns Jakob Berzelius (1779– 1848) and Johan Gottlieb Gahn (1745– 1818).
  • Although it is uncommonly discovered, selenium does exist in fairly pure type, complimentary in nature.
  • Selenium is a nonmetal. Like numerous nonmetals, it displays different 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 aspect. A single nut supplies enough selenium to fulfill the day-to-day requirement for a human grownup.
  • English electrical engineer Willoughby Smith (1828– 1891) found that selenium reacts to light (photoelectric effect), leading to its use 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 printer and copy machines, in steels, and in semiconductors.
  • There are six natural isotopes of selenium. One is radioactive, while the other five are stable. Nevertheless, the half-life of the unsteady isotope is so long that it is essentially steady. Another 23 unstable isotopes have actually been produced.
  • Some plants need high levels of selenium to endure, so the presence of those plants suggests the soil is abundant in the aspect.
  • Liquid selenium displays exceptionally high surface stress.
  • Selenium is necessary to a number of enzymes, including antioxidant enzymes glutathione peroxidase and thioredoxin reductase and the deiodinase enzymes that transform thyroid hormonal agents into other forms.
  • Roughly 2,000 tons of selenium are extracted yearly worldwide.
  • Selenium is most typically produced as a by-product of copper refining.
  • The aspect was featured in the movies “Ghostbusters” and “Development.” [5]

Chemical value of selenium

Selenium is an element present in the table of elements of all the existing components discovered by humans. The different chemical and essential homes of selenium are pointed out listed below.

Selenium inhabits the 34th element in the table of elements. This likewise implies that the atomic number of selenium is 34.

Like every other element on the table of elements, selenium has an atomic symbol, too, which is ‘Se.’ This atomic sign is used when expressing a chemical reaction involving selenium or one of its compounds.

  • The atomic mass, or weight, of selenium is 78.96.
  • Selenium’s state at room temperature level 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 only six of them are called steady isotopes.
  • Selenium is placed right below sulfur, and both aspects share comparable physical as well as chemical homes.
  • There are numerous allotropes of selenium, but only three are popular. The first one is amorphous selenium, which exists in powder and vitreous or glassy kinds. While in the previous, 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 stable allotropic kind 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 discovered separately in nature, but it is typically present as a compound such as zinc selenide or selenium dioxide.
  • It is also a part of uncommon minerals like clausthalite.
  • When it is utilized in chemical reactions, selenous acid is an efficient catalyst.
  • Out of all the selenium compounds, hydrogen selenide is the most poisonous one. It exists in gaseous type.
  • Taking selenium supplements when it is already present in high amounts in your natural diet can cause selenium poisoning.

Plants With High Quantities Of Selenium

Selenium’s natural abundance on earth can be found in numerous places. Research study has discovered that levels of selenium are high in seafood and some sort 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 amount of selenium in the food that grows in it. This is more 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 an abundant quantity of selenium, can gather the mineral too.

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

Use of selenium supplements

Individuals can get selenium through multivitamins and other dietary supplements. These might contain the mineral in various forms, including selenomethionine and sodium selenate.

The Dietary Standards for Americans, 2020– 2025Trusted Source motivate individuals to get their nutrients from food sources rather than supplements. Consuming a diverse and healthful diet is more important than concentrating on specific nutrients as the key to health.

When taking any supplement, it is important to buy it from a reliable source. In the United States, the Food and Drug Administration (FDA) does not keep track of supplements for quality, purity, product packaging, or strength. [7]

Signs of Selenium Shortage You May Be Disregarding

Selenium Shortage Symptom: You’re losing your hair

One of the most crucial things on selenium’s to-do list: assist convert your T4 thyroid hormone into the more active kind called T3, explains Little. If you run low, you may struggle with signs of hypothyroidism, among which is hair loss. “There can be many reasons for hair loss, so it’s your health professional’s job to understand what to evaluate for,” says Small.

Selenium Shortage Sign: You’re so exhausted

Another common hypothyroid symptom: fatigue. This might be a result of poor selenium levels decreasing your thyroid. “We want to knock out the obvious way of life aspects before looking at selenium,” states Small. That might be making sure that your diet plan has appropriate levels of carbohydrates, protein, and fat, looking for a vitamin D shortage, or examining iron levels. Then, make sure to follow these healthy habits for your thyroid.

Selenium Shortage Sign: You’re gaining weight

When you experience undesirable weight gain, you’ll wish to get to the origin. Once again, your thyroid’s thirst for selenium might play a role, and fixing that inadequacy can help your thyroid return online. Although Small very first take a look at diet when a client is gaining weight, she will consider testing selenium levels down the line. To discover why you’re packing on the pounds, think about these unexpected causes of weight gain.

Selenium Shortage Sign: You’re not operating at your best

Selenium is needed to form selenoproteins, states Little, consisting of glutathione peroxidase: “It is among the body’s primary methods to take harmful toxins and turn them into safe byproducts,” she says. “Deficiencies in this can lead to pretty serious health consequences,” she notes.

Selenium Shortage Sign: You may be at a greater threat for certain cancers

You’re probably up for doing whatever you can to prevent cancer– and maintaining maximum 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 in between selenium and cancer. They found a 31 percent lower risk of cancer related to higher selenium direct exposure, particularly with stomach, bladder, and prostate cancer. However other trials stopped working to reveal a benefit from selenium. Without concrete proof, the authors conclude that supplements most likely aren’t the answer. Instead, concentrate on the foods you can consume that will provide a series 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 certain you’re washing your hands routinely, you got the influenza shot, and you’re sleeping long enough and peacefully (try these 13 secrets from sleep physicians). But you’re not doing yourself any favors if your selenium levels are low. “Without the ability to effectively make glutathione peroxidase, your immune system can’t function appropriately, and you may discover you’re sick more often,” says Small.

Selenium Shortage Symptom: Your body is under a great deal of stress

Selenium is an effective disease-fighting antioxidant. “Oxidative stress causes damage to cells throughout your body. Any time you can protect your cells from oxidative stress is an advantage,” says Small. Find go-to methods to simmer down in the minute, sleep enough to assist your body recuperate, and eat well– including getting adequate selenium in your diet plan.

Selenium Shortage Symptom: You have shortness of breath

Those selenoproteins have another vital job: to secure your heart. A man who had Crohn’s disease stated his case: He suffered from inflamed legs and shortness of breath and it was later found that he had a selenium deficiency that caused his cardiac arrest. But the jury is still out on supplements: Although low selenium levels have actually been associated with a higher danger of heart problem, professionals are reluctant to recommend taking selenium pills. Rather, adhere to a healthy, selenium-rich diet. [8]

Selenium side effects

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

Long term use of high selenium dosages can lead to dangerous adverse effects. Stop taking selenium and call your medical professional simultaneously if you have:.

  • nausea, vomiting;
  • lack of energy, feeling irritable or extremely tired
  • loss of hair, mild rash, fragile or agonizing fingernails, or white streaks on the nails;
  • tremors, feeling light-headed;
  • muscle inflammation;
  • flushing (warmth, inflammation, or tingly feeling);
  • metallic taste, halitosis, strong body odor; or
  • simple bruising or bleeding. [9]
