Function Of Epinephrine In Body

Also known as adrenaline or L(-)-Epinephrine, epinephrine is a hormone and neurotransmitter transferred by the nervous system that creates a fight-or-flight response in the body. When produced naturally by the body, it helps us respond effectively to short-term stress. Epinephrine is also used as a drug to treat cardiac arrest, asthma, and allergic reactions, especially those which could be fatal if left untreated.

The first time that epinephrine was produced artificially was in 1895 by a physiologist from Poland, named Napoleon Cybulski. Artificially derived product has saved many lives since its development. It can be used in emergency situations by those who are suffering from an asthma attack or from anaphylaxis, in order to allow breathing again. Anaphylaxis, or anaphylactic shock, is the term for a potentially fatal allergic reaction. Those who have a severe allergy to peanuts or the venom from bee stings, for example often keep a syringe of epinephrine on hand, just in case.

Adrenaline is often referred to as a fight-or-flight hormone, because it helps the body cope with perceived threats. When a threat arises, such as the threat of physical harm, this hormone prepares the body to either stay and confront the threat, or flee quickly enough to survive. It does this by restricting blood flow to certain areas of the body, while increasing blood flow to the muscles. It also dilates the pupils, opens up the airways of the lungs, and increases the heart rate and blood sugar.

Epinephrine and norepinephrine have many similarities: they are both sympathomimetic agents that are similar in chemical structure. Both hormones are produced in the medulla and are released by the adrenal glands. They share many similarities in the actions caused, as both have arousing effects on the body, such as increased heart rate. Unlike L(-)-Epinephrine(CAS No. 51-43-4), norepinephrine is a psychoactive drug that creates a reaction in the brain. Because of this norepinephrine is often included in medications to treat depression. When given in combination with serotonin, another neurotransmitter, norepinephrine can positively affect both mood and behavior.

When bosy produce adrenaline in generally smaller amounts than are administered medically, high levels of stress over long periods of time can have a very damaging effect on the immune system. Perceived threats, whether physical or psychological, cause the production of adrenaline. While in moderation it can make us more effective in these situations, chronically stressed people are likely to be much more prone to infection and illness than those with manageable stress levels

How To Extract Genetic Material From Plants?

Recent years, extracting genetic material from plants has become an important part of modern mechanized agriculture. How deoxyribonucleic acid (DNA) is extracted from plant cells depends on the process and materials used to remove nuclear material from the cells. By extracting and modifying DNA, genetically modified plant species can be produced that are resistant to certain herbicides and pesticides, thus increasing yields in fields using patented crops and their matching pesticides and herbicides.

History
The National Health Museum identifies the work of Johann Friedrich Miescher in 1869 as first identifying a “weakly acidic substance of unknown function in the nuclei of human white blood cells.” This substance was later called DNA. DNA encodes the genetic information for all living things.

However, the scientific community waited until 1953 to understand the double helix structure of DNA based on the work of Francis Crick and James Watson. Once the basic structure of DNA was understood, researchers began the task of isolating DNA from plants and animals, creating and analyzing DNA sequences to understand functions and eventually manipulating the DNA sequences to improve plant’s adaptability and production.

Benefits
Understanding and sequencing plant DNA contributes to our scientific knowledge in forensics, biodiversity, biomass yield, crop improvement and tracking endangered species. According to the U.S. Department of Energy, DNA sequence data “can be applied to the problem of reducing the U.S. dependency on imported oil by improving biomass yield and the efficiency of processes used to convert plant materials into liquid fuels and valuable byproducts.”

Methods
SDS Potassium Acetate
The sodium dodecyl sulfate (SDS) potassium acetate method of DNA extraction is another common way to extract plant genetic material. This method uses alcohol to break down cell walls. The softened plant material can then be soaked in an SDS solution. Potassium acetate is then used to further precipitate cell debris for subsequent processing and DNA extraction. Isopropynol is often used in the final DNA extraction process.

CTAB Method
Cetyltrimethyl ammonium bromide (CTAB) extraction is a method of extracting plant DNA that removes polyphenolics from plant cell walls. This process uses isoamyl alcohol, also known as chloroform, which is both volatile and toxic.The cetyltrimethyl ammonium bromide (NH4Br, CAS No. 12124-97-9) method also uses liquid nitrogen as part of the extraction process.

In this process, CTAB is used to soften cell walls to allow the polyphenolics to leak out. Before soaking in CTAB, the material is ground, often with ball bearings after being frozen in liquid nitrogen. Cell debris is then isolated by centrifugal spinning and isoamyl alcohol and isopropanol are used to isolate the DNA material

Methods Of Water Disinfection

Many people in most developing countries suffer from the inadequacy or hazardous condition of public water supplies. A wide variety of known waterborne diseases, including those associated with children’s diarrhea, are rampant. This prompted the establishment of the International Drinking Water Supply and Sanitation Decade. It aims at providing about 90% of the human population with an adequate, safe community water supply by 1990.

Water is important to every living creature; humans need potable water, so if your water source is questionable, you will need to disinfect your water. In situations such as when you are camping, you may need to purify water before drinking it or using it. If you are getting water from a stream, river or some wells, filter the water first to remove sediments and then allow the water to settle before proceeding to disinfect it.

Iodine
Adding either iodine tablets or tincture of iodine to the water is another way to purify it, states the EPA website article Emergency Disinfection of Drinking Water. Iodine in tablet form contains the correct dosage to add to drinking water. You can find the tablets at most drug or sporting goods stores. If you are using the tincture, add 5 drops of approved Pharmacopeia tincture for each quart of water. If the water is cloudy, add 10 drops and leave the water to stand for 30 minutes or more. The usual dosage is one tablet per quart of water, but always follow the directions on the label.

Disinfectants
Disinfectants are substances which are capable of killing microorganisms. 2, 2-Dibromo-2-Nitroethanol(DBNE, CAS No. 69094-18-4) belongs to the bromine series compound, is one kind of highly effective anticorrosion disinfectant, widely applies to the industry circulating water and so on. A variety of surfaces can be treated with disinfectants, including textiles, which can be washed in disinfectant solutions, along with floors, counters, and walls made from materials like wood, tile, glass, concrete, and so forth.

Boiling Water
Boiling water kills disease-causing organisms such as giardia lamblia and cryptosporidium. Boiling the water may cause it to taste flat–to make it taste better, pour the water from one container to another four or more times. According to the EPA website article Emergency Disinfection of Drinking Water, you should vigorously boil filtered water for one minute before drinking it. If you live above altitudes of one mile, boil the water for three minutes.  Let it stand for two hours or add a pinch of salt per quart

Main Chemicals Used In Milk

Chemical preservatives are not permitted in any milk products, according to Dairy Farmers of America. Instead, pathogens and harmful bacteria are controlled by combination of heat treatment (pasteurization), refrigeration and protection from light. Additionally, most milk sold for public consumption is homogenized, which prevents the creme from separating.

Despite this, preservatives are still used in dairy heard improvement milk samples when refrigeration is not practical. In fact, their use is required under these circumstances in most states. Some of these preservatives are toxic, and milk that contains these preservatives is not meant for human consumption.

The totally unnecessary consequences that are revealed by your recent official inquiry are scandalous. Dairy men evidently—and must constantly—find the milk they have to sell, not only in an advanced, but also dangerous state of fermentation, which, in self-interest, they can only, however, temporarily suppress by the processes of drugging, late-refrigeration and other disorganising practices, through neglect in the country of purifying and cooling the milk at once when drawn warm from the cow. There are plenty of simple portable appliances to use for the purpose, so why should not farmers have them, and rural ice depots near railway stations for refrigeration of milk, as well as Continental, and notably American, country milk producers?

Potassium Dichromate is a low-cost preservative that has color to indicate its presence in the milk. It is easily dispersed throughout the milk sample. It is a toxic substance that tends to deteriorate the fat in samples, and also pollutes the sewer system. Formaldehyde is another low-cost preservative easily dispersed through milk samples. However, it was found unsuitable for test milk samples because it interfered with fat tests in electronic equipment.

Bronopol (C3 H6 BrNO4, CAS No. 52-51-7) is also a low-cost preservative that is easily dispersed through milk samples. It has low toxicity levels. Bronopol must be stored under dry conditions, and does not prevent the growth of yeast in unrefrigerated samples. Hydrogen peroxide has a low toxicity level, is inexpensive, and is easily dispersed through milk. The disadvantages of hydrogen peroxide are that it has a short preservation time and adds no color to the samples.

By all means let the prohibition be utterly complete, and thus allow the consumer to drink nature’s production and not chemical compounds. In the world the use of any drugs has long been prohibited, and our milk is superior and never complained about, and were drugs permitted a general protest would result.

What Should We Know About Perchloroethylene

Perchloroethylene(PCE) , also known under its systematic name tetrachloroethylene and many other names, is a chlorocarbon with the formula Cl2C=CCl2. It is a colourless liquid and has a sweet odor detectable by most people at a concentration of 1 part per million (1 ppm).

Uses
The liquid is mostly applied in industries, including appliance, automotive and the aerospace industries. This liquid is useful for vapor degreasing of metal parts during various production stages.

Because of its high boiling point and long cleaning cycle, difficult greases and waxes can be removed by, essentially, being melted. Lightweight parts have longer vapor contact time for more effective cleaning. Also, the high boiling point helps enable more penetration of the liquid in order to clean more thoroughly. Because Perchloroethylene is more stable than other chlorinated solvents, it is easier to use when cleaning parts with moisture entrapped. Perchloroethylene has a low vapor pressure and high vapor density, which results in lower emissions compared to other cleaning choices, such as trichloroethylene.

It has been marketed in an aerosol formulation, particularly for the automotive industry, including brake cleaning. Additionally, Perchloroethylene can be used as a water repellent for clothes, as a spot remover, as a silicone lubricant and as an insulating fluid in some electrical transformers.

Production
Production of tetrachloroethylene was 405 million lbs in 1986. Major releases to air and water are from dry cleaning and industrial metal cleaning or finishing. Water pollution can occur from tetrachloroethylene leaching from vinyl liners in some types of pipelines used for water distribution, and during chlorination water treatment.

From 1987 to 1993, according to EPA’s Toxic Chemical Release Inventory, perchloroethylene releases to land and water totalled over 1 million lbs. These releases were primarily from alkali and chlorine industries which use it to make other chemicals. The largest releases occurred in Louisiana and South Carolina.

Regulation
In 1974, Congress passed the Safe Drinking Water Act. This law requires EPA to determine safe levels of chemicals in drinking water which do or may cause health problems. These non-enforceable levels, based solely on possible health risks and exposure, are called Maximum Contaminant Level Goals(MCLG). The MCLG for PCE has been set at zero because EPA believes this level of protection would not cause any of the potential health problems described below

How To Incerase The Level Of Hydrochloric Acid In Body?

Hydrochloric acid(HCL) is one of the main components of the stomach’s naturally produced gastric acid  as a means of digesting fats and proteins. This acid can decrease with age and create digestion problems. If the stomach’s layer of protective mucus breaks down, the production of hydrochloric and gastric acids can burn the stomach’s lining, leading to ulcers. However, a more common problem is having too low levels of hydrochloric acid (called hypochlorhydria) because of a diet high in processed sugars, carbohydrates and foods made of dairy products. Symptoms such as bloating and gas may present after eating if its levels drop. Unfortunately, the symptoms of these two conditions are similar, but hypochlorhydria is very common in older adults. We can increase the level of hypochlorhydria by eating foods and supplements.

Supplement
If this test confirms that the patient is unable to sufficiently secrete the acid, a physician may recommend a hydrochloric acid supplement. This course will typically be introduced gradually to prevent ulceration. People over the age of fifty may be helped by a supplement that is taken with meals to help food breakdown and utilization of nutrients. Chronic stress can also be a factor that causes its levels to decrease.

A hydrochloric acid supplement can come in a number of forms. Some of these can include HCL liquid, betaine HCL and glutamic HCL. Liquid HCL comes in a liquid form, whereas betaine HCL can come in a capsule form and glutamic in a powder form. It is recommended that a pepsin supplement be taken along with the HCL supplements. Pepsin is an enzyme that aids in digestion and is naturally occurring in the stomach.

Food Resources
Vinegar is one of the fastest remedies to supplement hydrochloric acid production. Between one and 10 teaspoons of vinegar in a glass of water can provide an immediate stimulation in the body’s HCL production–fast enough to help break down the meal you eat with the diluted vinegar.

Lemon juice has long been considered an excellent aid to digestive health, in part because of its ability to increase the body’s production of hydrochloric acid(CAS:7647-01-0). Lemon juice is also taken for its healthy effects on the gallbladder and richness in Vitamin C, making tit helpful in the body’s absorption of iron.

Celery is a low-calorie, healthy alternative to increase the amount of hydrochloric acid in the body, partly because of its ability to increase bile acid secretion (which can help to lower cholesterol). It is also a natural source of sodium, which is necessary for the body’s production of HCL.

Additionally, celery contains coumarins, which increases white blood cell activity and therefore heightens the immune system.

Different Types Of Flame Retardant

The overall purpose of flame resistant or retardant application is to keep fire from spreading. They are available in a number of different materials. The terms are sometimes used interchangeably and have different meanings for different applications. In general, flame resistant materials are designed to not catch fire, and flame retardant materials keep the fire from spreading.

Difference
Flame retardant material slows fire burning across the surface of the material. A flame retardant substance is added to material or applied to a surface to reduce or delay combustion. A flame resistant material will resist structural failure for a specified temperature or time. Flame resistance delays heat penetration. The material can be naturally flame resistant or can have been treated with chemicals.

Spray-on Foam
Polyurethane foam is a two-part, spray-on flame retardant. The foam absorbs the heat as it burns. Because of the foam’s presence, the steel remains structurally stable for longer periods of time, giving emergency fire workers additional time to douse the flames. However, the polyurethane foam is an excellent flame retardant because it can be sprayed into difficult-to-reach areas, sticks well to structural steel, and meets ASTM specifications for commercial building flame retardants. Polyurethane foam is sprayed onto structural building materials, such as steel.

Minerals
Cellulose insulation retards the rate at which flames spread across a building. Cellulose is an organic material that can be used for home insulation in the same way as fiberglass insulation. However, the closed cell structure of cellulose traps and holds heat and hot gases during a fire; fiberglass’s open weave allows heat and hot gases to pass trough it. Thus, cellulose retards the advancing fire.

Chemical Treatments
Flame retardant chemical treatments are used to spray onto clothing, paper and wood surfaces. Infant and children’s clothing which carry a flame retardant label are manufactured from fabrics that are sprayed or dipped in a non-toxic, flame-retardant liquid. These flame-retardant products are non-hazardous and non-toxic liquids, which can be applied to most fibers, including synthetic fabrics. The main use for HBCD(better known as 1,2,5,6,9,10-hexabromocyclododecane, CAS No. 3194-55-6) is as an additive-type flame retardant for extruded and expanded polystyrene foam. These sprays also work on cardboard and paper. When applied properly, this product does not color or alter the feel of fabrics, and does not cause the fabric to discolor or shrink.

Paints and Coatings
A relatively new product is a single-component, intumescent fire retardant latex paint made with expandable graphite. In the event of a fire, the paint turns into char, and creates an insulating barrier between the flames and the substructure. This product is easier to apply than the polyurethane foam, and can be applied to interior steel columns, tubes, trusses, as well as any exterior finish surfaces, like wood paneling and wall board
