Blood Drug Testing Procedure In Sports

Blood testing is used in the identification of drugs like EPO and artificial oxygen carriers by examining the haematocrit or blood count. Additionally, a blood profile of an athlete is developed to figure out average readings for each individual. This will help for blood doping tests later. The anonymity and representative methods are same as that of urine sampling.

The athlete is suggested to select and verify the testing and collection apparatus before a phlebotomist (an individual trained to draw blood) takes two samples of blood promptly into bottles A and B. The bottles stay in the custody of the athlete (who is always guided by an official) until they are closed in the sample collection kit. Then, samples are delivered to a lab for testing. If the sample A is positive, then B sample is tested. If the result is positive with sample B, concerning governing bodies are informed.

Know about Dental Sealants

Dental sealants is one of the dental procedures. It is used to prevent the  formation of cavities in a mouth. Dental sealants are made of thin plastic material which can be applied to the surface of the backside of the tooth to prevent formation of bacteria or plaque which can lead to tooth loss. In order to prevent plaque, dental sealants are used and applied on the surface of the backside of the tooth. 

Generally backside teeth contains grooves and whenever we eat food, food substances are remained in these grooves. This can lead to formation of plaque which results in tooth decay, which in turn leads to tooth loss.

If we apply sealants to those surfaces of back teeth, the sealants protect back teeth against the formation of plaque. These sealants are available in clean white color. Dental sealants are applied to children and teenagers because in these ages only there will be more chances of forming the plaque.

So, dental sealants are useful for keeping your teeth clean.

How Drug Testing Is Done In Sports?

Most of the drug testing in sports aims at the performance enhancing drugs. Typical culprits are athletes who take testosterone to build muscles and erythropoietin which builds strength by intensifying red blood cell amount to carry oxygen. Drug testing is also done for cocaine and even alcohol and other banned list of drugs.

The labs uses a scientific sorter technique known as chromatography to detect the drugs. Chemists will simplify a mixture into its constituents depending on their molecular weight, acidity, or readiness to disperse in water. They pass a sample upon a column filled with a material, like silica, a finely crushed glass which combines with the mixture to isolate it. Molecules will get separated by the time they take to run over the column. Then, technicians will find the mass of every molecule. These two measurements jointly serve as an indication for a drug.


Sensitive testing can explain difference between testosterone which is made synthetically or naturally produced in the body by considering carbon. Synthetic testosterone is deficient in carbon thirteen. In this way they can detect the small quantities of synthetic testosterone in athlete's urine.


Chemists test for erythropoietin in other way as it is a large protein. A high molecular weight (30,000 compared to 400 for a steroid), is too big to pass over a column. Technicians attach a sample in a gel and pass it under an electrical field and identifies erythropoietin molecule based on its weight.

Impact of Drug Abuse on Driving

Drugs are not only dangerous due to their harmful health effects, but also due to their impact on the physical, mental, social and driving skills of a person. Today, many people are driving under the influence of substances. According to National Survey on Drug Use and Health 2008, about 10 million people aged 12 or above drove under the influence of illicit drugs in 2008 in America. That means about 4 percent of the population aged 12 years or older drove under the influence of the drugs.

One of the main concerns of driving under the influence of drugs is that they act on the brain and impair the person’s motor skills, reaction time, and judgment and hand eye coordination. Drugged driving not only puts the abused driver at risk, but also others who share the road along with him.

Marijuana is the commonly abused illegal drug detected in impaired drivers, or motor vehicle crash victims. Many people drive under the influence of alcohol and become victims of crashes. Alcohol abuse can be easily detected by alcohol breathalyzers. The blood alcohol concentration (BAC) more than 0.08% is said to impair a person’s driving performance. So BAC concentration of 0.08% is fixed as the legal limit in America. Other drugs often used by drivers include benzodiazepines, cocaine, amphetamines and opiates.

Application Of Barcode Printers In Government And Electronics

Barcode has wide range of applications in many industries. Few applications of barcode printers and labels in Government are:
  • Used to create employee ID and visitor badges using easy-to-use desktop printers
  • Used effectively to perform record keeping and fulfill data recording requirements with bar codes.
  • Used for healthcare to produce protected patient wristbands, track equipment and supplies, enhance inventory management and security in the pharmacy, and used to guarantee patient safety using unit-of-use pharmaceutical labeling.
  • Used to generate security and tracking programs for all personnel, visitors, and equipment using wide range of printers for producing asset tracking tags, shipment protection, component ID labels, location labels to safeguard tour and abandoned check-in/check-out applications, document authentication, etc.
Few applications of barcode printers in electronics are:
  • Used to produce high resolution barcoding for circuit boards
  • Serial plates
  • Product identification labels
  • UL-recognized/CSA-accepted solutions
  • Used to create tamper evident labels
  • Used to create self-laminating piggyback labels for rough environments

Three Fitness Training Mistakes

Beginners of physical fitness training must take many precautions before doing workouts in order to prevent injuries. Three common fitness training mistakes are:
crossfit Brooklyn

Overtraining: Overtraining is the most commonly observed mistake in fitness training and in mostly beginners. It causes heavy reaction to those who proceeds to work the body outside the limits of manageable repair. Overtraining is caused due to body's inability to recover the physical stress associated with fitness and exercise and some times result in muscle tear, intensely weakened immune system, and chronic fatigue. The excellent goal to get into a good shape will not be achieved if training is done every day in a week for hours at a time. Rest should be taken to make the body to naturally recover and strengthen the muscles for future session.

Elimination of carbohydrates: Many publicly marketed diets which emphasize the disaster related to carbohydrate consumption, presumes that weight loss can be only attained by complete absence of carbohydrates in a given diet. This is possibly the most common misconception observed in diet trend followers today, and moreover a dangerous and unhealthy method to follow.

The truth is, sugars, corn syrup, bleached flour, and other elementary carbohydrates are all supplements and ingredients which must be avoided, as they will stimulate negative effects within the body. Complex carbohydrates found in whole grains, wheat, oats, and more are very essential to the body, and helps in weight loss by retaining and increasing the metabolism even in physically inactive state.

Too much cardio: Cardio workout practices are outstanding, and very important for the improvement of a healthy lifestyle. But too much cardio creates undesirable problems in fitness and health. Over-doing of cardio exercises makes the body to begin extracting energy from its muscle storages, instead of utilizing its fat and carbohydrates storages for energy and nourishment. This makes the body to exhaust drastically, and also reduces the strength of immune system and mental process to a very low level. Cardio routines should not be done more than 45 minutes in the beginning in order to have a healthy life.
