Use this video to show students about the back of the Makey Makey and how to light an LED with a coincell battery. Explain that they should NOT light an LED by placing the positive leg on the 5V output, as it is too much power for a multilayer pcb normal LED. Instead, they’re going to use the “Key out” pin on the Makey Makey, so they’ll have to build a switch or close the circuit by hand to turn on the LED.

Honey: Benefits, Applications And Properties

In addition, components of honey polyphenols counteract direct apoptotic challenges from amyloid beta, induced methylmercury and retinoid. Raw honey and honey polyphenol reduce microglia-induced neuroinflammation induced by immunogenic neurotoxins or ischemia damage. Most importantly, honey polyphenols counteract neuroinflammation in the hippocampus, a brain structure involved in memory. Honey polyphenols prevent memory impairment and induce memory production at the molecular level. Several studies propose that modifications of specific neural circuits underlie the improvement of memory and neuropharmacological effects of honey. However, more studies are needed to determine the ultimate biochemical impact of honey on mitochondrial dysfunction, apoptosis, necrosis, excitotoxicity and neuroinflammation, and anxiolytic, antitinociceptive, anticonvulsant and antidepressant activities need to be investigated in more detail.

Liver activity of superoxide dismutase also decreased in juvenile rats supplemented with 5 g/kg of Lamb honey. Gelam’s honey reduced oxidative damage in young and middle-aged rats by modulating the activities of antioxidant enzymes that were more prominent at a higher concentration compared to the lower concentration. Another study indicates that honey has these antioxidant and free radical-clearing properties, mainly because of its phenolic compounds. Type 2 diabetes consists of progressive hyperglycemia, insulin resistance and β-pancreatic cell insufficiency, which can result from glucose toxicity, inflammatory cytokines and oxidative stress, and is responsible for 90-95% of all diabetes cases. The results indicated the in vitro antioxidant property of Gelam’s honey and flavonoids in hamster β cells, creating a protective effect against hyperglycemia.

The main composition of honey is carbohydrates that contribute 95-97% of the dry weight. In addition, honey contains important compounds, such as proteins, vitamins, amino acids, minerals and organic acids. Pure honey also consists of flavonoids, polyphenols, reducing compounds, alkaloids, glycosides, cardiac glycosides, anthraquinone and volatile substances.

Cancer cells are characterized by insufficient apoptotic turnover and uncontrolled cell proliferation. Honey causes apoptosis in many types of cancer cells due to depolarization of the mitochondrial membrane. Honey increases the activation of caspase 3 and the cleavage of poly (ADP-ribose) polymerase in human colon cancer cell lines, which is related to its high phenolic component. In addition, it does apoptosis by modulating the expression of pro- and antiapoptotic proteins in colon cancer.

Pasteurized or “regular” honey is treated with heat, which kills yeast (extending shelf life) and potentially harmful bacteria, Jones explains. Honey naturally contains botulism spores, which are toxins released by a bacterium called Clostridium botulinum, according to the National Organization for Rare Disorders. And while “the amounts fit durch den Winter in honey are generally not significant enough to affect healthy adults,” they can technically lead to botulism, a rare but potentially fatal disease that can cause paralysis, according to Doebrich. However, pasteurization removes spores, making pasteurized honey the optimal choice from a food safety standpoint, Doebrich says.

However, some environmental factors can strongly influence the composition of honey, such as temperature and humidity. The antimicrobial activity in most honeys is due to the enzymatic production of hydrogen peroxide. However, honey without peroxide (namely manuka honey) exhibits significant antibacterial effects even when hydrogen peroxide activity is blocked. Manuka honey is a unique type of honey that is made in Australia and New Zealand by bees that pollinate the native shrub of leptospermum scoparium. The mechanism may be related to honey’s low pH and high sugar content that is enough to stunt the growth of microbes, according to the National Center for Biotechnology Information, part of the U.S.

The antitumor effects of honey were strongly correlated with its ability to induce cell apoptosis and with its antioxidant power. The effect of Aloe vera along with honey has also been studied and the whole has the ability to modulate tumor growth, reduce cell proliferation, and also increase sensitivity to apoptosis. The antitumor effects of honey were strongly correlated with its ability to induce cell apoptosis and with its antioxidant activity.

For example, a 2010 study looked at the effects of honey compared to those of cough medications and antihistamines on nocturnal cough in children with upper respiratory tract infections (e.g., flu, tonsillitis, sinus infection). The study found that honey provided the most symptom relief for all three substances. Additional research also supports this, suggesting that the benefits of honey may make it an effective cough treatment. If you’re on a mission to strengthen your body’s natural defenses, look for honey. But antioxidants like those found in honey can help keep these free radicals at bay.

Honey contains mainly sugar, as well as a mixture of amino acids, vitamins, minerals, iron, zinc and antioxidants. In addition to its use as a natural sweetener, honey is used as an anti-inflammatory, antioxidant and antibacterial agent. People often use honey orally to treat cough and topically to treat burns and promote wound healing. Honey contains antioxidants, such as phenolic compounds that prevent cellular oxidative damage that leads to aging, diseases such as cancer, metabolic disorders, cardiovascular dysfunction, and even death. The antioxidant effect of honey was compared in young and middle-aged rats, rats were given pure water, which were supplemented with 2.5 and 5.0 g / kg of Gelam honey for 30 days. The results showed that honey supplementation of Gelam reduced DNA damage, plasma levels of malondialdehyde and glutathione peroxidase.

Influenza is a highly contagious respiratory disease of viral origin that causes even more deaths than respiratory syncytial virus at all ages, except in children under one year of age. Influenza viruses are transmitted through the air from person to person, especially from droplets emitted when coughing and sneezing, and pose a serious threat to human health, and there is an urgent need to develop new drugs against these viruses. The results showed that honey in general, and in particular Manuka honey, has a powerful inhibitory activity against the influenza virus, demonstrating a potential medicinal value. In addition to honey, propolis has also been studied against the flu virus and seems to reduce the activity of the flu virus.

What Is Suction Cup Therapy?? Advantages And Applications

The detoxifying effect of Cupping on the skin and circulation is also significant, with a visible improvement in skin color after three to five treatments. The suction cup removes toxins and improves blood flow through veins and arteries. Especially useful for athletes is the potential of suction cups to illuminate muscle spasms.

In dry suction cups, the caregiver soaks some alcohol material, turns it on and places it in the cup to remove oxygen. In wet suction cups, the caregiver pierces the skin slightly to draw a small amount of blood and then places the cups on the patient’s body. In wet suction cups, also known as “hijama”, the practitioner puts the cups on the skin before making piercings or needle cuts. After a few minutes of suction, the cup is removed so that the professional can infuse small cuts on the raised skin to release blood and toxins. The therapist can use pressure to accelerate blood flow before placing another cup on the site for a few more minutes.

A therapeutic treatment for the suction cup includes heating and placing cups, usually made of glass, on the skin. Heating the air in the cup creates a vacuum and when applied to the skin, the tissue is inserted into the cup. This increases blood flow, releases the fascia or connective tissue and is believed to stimulate healing. It is similar to how deep tissue massage can be used to break scar tissue and reduce pain.

Let’s move forward quickly to today and suction cups have become a very popular form of alternative medicine. The time it takes to experience the benefits of suction cup therapy is unknown and may depend on the specific condition. For example, the 2018 review suggested a possible protocol for low back pain of five sessions of dry suction cups with a 3-7 day break between sessions. The wet suction cup involves piercing the skin before the suction starts, removing some of the person’s blood during the procedure. This type of suction cup is less common in the United States, where professionals must have a permit for medical professionals.

Instead of putting pressure on muscles, suction is used to lift the skin and muscles. If you’ve been interested in trying a suction cup therapy, here are nine benefits to expect. Once suction has occurred, the cups can be moved gently through the deep tissue massage skin (often called “sliding puppies”). Medical massage oils are sometimes applied to improve the movement of glass cups along the skin. Sucking on the cups ensures that the skin and the superficial muscle layer are lightly pulled onto the cup.

The process involves the use of heated or suction cups, except before the cups are applied, small punctures are produced on the skin surface. Once the cups are placed over the cups, the suction force draws blood from the penetrating plates. Cutouts can increase blood circulation in the area where the cups are placed. The main principle is to create a wave of blood flow under the cup to bring in fresh, oxygen-rich blood cells along with white blood cells and receptors to relieve pain so that local healing can take place. Originally from China, suction cup therapy is an ancient and universal practice with a rich usage history that includes both East and West. Cutting is a healing method that uses suction to create negative pressure to move the skin away from the underlying tissues.

Just stand still and have your certified suction cup therapist apply this therapy can have positive effects on your health. The suction cup is similar to receiving a deep tissue massage because it provides muscle relief. Windy therapy helps increase the pressure on tight muscles and provides a relaxing experience. Combined with being quiet in a quiet environment, the process can be extremely relaxing. In the 1950s, Chinese and Russian doctors and scientists conducted extensive studies to determine the effects of suction cup therapy and found that strong suction was in fact clinically effective and beneficial.

The reduction has even shown positive effects when used to relieve cancer pain compared to pharmaceutical drugs. By creating suction and vacuum pressure, you can smooth and strengthen tight muscles, loosen adhesions and remove limiting connective tissues. It can be used to move deep inflammation to the skin surface to release it and drain excess fluid and toxins by opening the lymphatic pathways.

Since suction cups also help reduce inflammation in the body, athletes can expect an improvement in their blood flow, which in turn is beneficial when it comes to boosting their body’s immune system. TCM teaches that it is the stagnation of qi and blood that causes pain and illness. The suction cup stimulates the local blood circulation of qi and blood in the area to be treated, so that swelling, pain and tension are resolved. From a Western physiological perspective, the suction cup loosens the connective tissue or fascia and stimulates blood flow to the surface. Cutting stimulates tissue relaxation and better cell-to-cell communication. Research by the American physiologist and acupuncturist Helene Langevin has documented changes at the cellular level using an ultrasound camera.

Increased blood flow allows your body to wash away toxins, restore lymph circulation and help wash away edema, reducing scars. Studies have shown the positive effects of suction cups on stretch marks and scars, even in areas far from the area where the cups are applied. By sucking the cups, the circulation to the area where the cups are placed is increased.

3 Reasons Why Pneumatic Cylinders Fail In Applications

Even with an extensive and consistently applied preventive maintenance program, pneumatic cylinder repairs will still be required. Likewise, a pneumatic device can drift when power is turned off, or a controlled device with a two-position valve can move unexpectedly when air is reapplied, and these conditions should also be considered. The soft starter valve in the air preparation unit helps to mitigate the Pneumatic air bladder impact in these situations, but movement by replication of air pressure can still cause damage to the machine. Therefore, the valve must be held in place by a fail-safe device, such as a spring, and / or properly interlaced. When an emergency stop is pressed, the pneumatic solenoids are made without tension. If possible, direction control valves should return to an exhaustive state of power loss, Figure 2.

Even the strongest and most resistant hydraulic systems fail from time to time and can contain 100 explanations. Many of these failures can be prevented if conditions are properly controlled and a proactive rather than reactive position is taken to maintain the hydraulic system. But if something goes wrong, count on Air-Way Global Manufacturing to keep it running. With an extensive inventory of hydraulic mounting and hose mounting, we specialize in short delivery times and have products at hand and ready for shipment in an instant. It is often easy to know when a hydraulic system fails: symptoms can be: high temperatures, low pressure measurements and slow or erratic operation are obvious problems.

During installation, a poor location choice that would introduce contaminated air inlet into the air compressor can start a ticking time pump in case of air compressor failure. Failure to verify correct alignment of the clutch after transmission and reception may result in sudden failure due to bearings for both the electric motor and the compression unit. Failure to verify that the electrical specifications and infrastructure are correct may cause critical disturbances that are unlikely to be covered by the warranty.

Regular maintenance and correct use of tools also help extend tool life and optimize performance. Polluting jam: Your pneumatic system may fail if your parts are blocked with contaminants such as solids, water and oil. Prolonged exposure to industrial environments containing chemicals, paints or welding spatter results in harmful seals, covered holes and broken surface finishes.

We can trace most hydraulic problems to some common causes, which are listed below. There are many standards to consider when designing and installing pneumatic components on a machine. Air preparation, valves and cylinders play a key role in safe pneumatic control. Proper design and application of these and other pneumatic system components, along with compliance with basic pneumatic design requirements, will result in a safer machine. Much of what is stated in the above standards is beyond the scope of this article.

In these high-risk applications, redundant and monitored valves should be used to protect operators by standards. Air preparation must also include an air filter with filter elements from 5 to 40 microns, a break-resistant container, a metal cover and manual, semi-automatic or automatic drainage. The filter automatically removes moisture and provides protection against particle contamination, a common cause of failure. A controller must be used, integral or separate from the filter, it must be relieved itself and contain a meter. The placement of your air compressor is crucial for the livelihood of your entire compressed air system.
