Benefits of eggs in one’s diet

milica Articles, Diet Leave a comment   , , , , ,

Our organism needs many substances daily in order to maintain itself. Those substances we receive through our food. A good diet is extremely important for our health. A diet should include eggs. However, the eggs we eat should be of high quality so that they serve well enough their purpose in our meals.

Why are eggs important for our health and general condition?

Eggs are rich in many essential for the organism substances.  Each egg contains the following:

  • Choline – 26.5%
  • Tryptophan – 25%
  • Selenium – 22%
  • Iodine – 18%
  • Vitamin B2 – 15.2%
  • Protein – 12.5%
  • Molybdenum – 11.3%
  • Vitamin B12 – 9.1%
  • Phosphorus – 8.6%
  • Vitamin B5 – 7%
  • Vitamin D – 6.6%
  • Calories – 4%

Organisms are complexes of systems, which contain organs. Organs are made out of tissues, which are made out of cells. This makes obvious that the cell is the smallest but essential living structure , which builds up the body. Cells are made out of inorganic and organic substances. The basic organic substance which defines the structure and functions of the cell are the proteins. They are also called polypeptides. Simple polypeptides contain of only amino acids. They bond with each other through peptide bonds and build the protein.  People and animals receive the needed amino acids through their food. The amino acids of the proteins are 20 different ones. 8 of those 20 we cannot synthesize in our cells and therefore can receive them only through our food.  Eggs contain 12.5% proteins, which make them one really great source for this essential organic substance for the body.

The rest of the substances in eggs are really important as well. For example,  Choline is part of different fat containing structures of the cell membrane. Also it takes part in substances in the brain.  For example phosphatidylcholine and sphingomyelin, which are important constructive substances in the brain, or acetylcholine which is a neurotransmitter, taking part in transmitting signals from one neuron to another. Another example is the Vitamin B12 is important for producing the red blood cells or erythrocytes. They are the basic component of the blood and are important for carrying oxygen and carbon dioxide in the organism. Vitamin D is essential for the bones – their growth and health.

How many eggs can you eat?

Usually a good amount is 40 eggs per week. That mean maximum of 5 or 6 eggs per day. The fact that eating too many eggs is unhealthy is because of the cholesterol, contained in them. Cholesterol is really important for the cell membrane and other structures in the cell. When taking in too much quantities, it accumulates on the wall of blood vessels and that leads to different cardiovascular problems.

 


Tourette syndrome

milica Articles, Diseases Leave a comment   , ,

There are syndromes that do not have a lethal outcome in the fetus or the child. Such a syndrome is the Tourette one.  People with this syndrome undergo so called tics, which can occur repetitively during the day or night during sleep. However, the frequency of the tics during sleep is decreased.

What is typical of the tics?

The tics are characterized by involuntary movements and vocalizations.  There are two types of tics – simple and complex.

Simple tics include brief, sudden movements, which are triggered by a limited number of muscle groups.  For example such are eye movements, shoulder shrugging, grimaces and others.  There could be also vocalizations such as throat-clearing and grunting sounds.

Complex tics include movements which are triggered by a larger number of muscle groups. Typical of those tics are that there could be several specific movements at the time. For example head jerking and shoulder shrugging. The vocalizations also include throat-clearing, grunting, sometimes even barking. Complex tics are characterized by more noticeable vocalizations that include whole words and phrases, which are inappropriate. For example swearing. None of the movements or vocalizations are voluntary even though in some of the cases it seems as if they are.

There is another classification of the tics. According to it, tics can be vocal or motor.

A really dangerous side of these tics is that with the complex type there could be movements that threaten the health or life of the person. For example hitting oneself.

What can trigger a tic?

Tics can be triggered by seeing or hearing other people making movements or sounds similar to the ones during a tic. An example of this is hearing somebody clearing their throat.

Is there a treatment?

So far there is not a medicine that can completely cure this syndrome. There are neuroleptics that can relieve the symptoms of people with more complex tics that interfere with their normal functioning. Those neuroleptics have also side effects, such as Parkinson like symptoms, tremors and others. One effective way of avoiding these side effects is by taking at first a normal dose of neuroleptics which with time decreases before the side effects appear.


Embryology – the study of early human development

milica Articles, Embryology, Microbiology Leave a comment   , , , , , ,

What is Embryology?

Embryology is a study following each stage of early human development, the so called prenatal development. The name derives from the Greek word “embryo” which means unborn and “logus” which stands for science, therefore this is a science which studies the unborn.

What is a prenatal development?

Embryology analyses all of the processes that form the human being – from the forming of the reproductive cells all the way to the formation of the fetus body and organs.  Prenatal development means the developmental process of forming a fetus from a single cell. The whole process could be derived in two stages. The first one is called organogenesis and the second is the fetal period.

Organogenesis includes the first 8 weeks after conception. It studies the processes of forming the zygote and the organ primordia. The zygote is the diploid cell forming as the result of uniting the male reproductive cell – sperm and the female reproductive cell –  oocyte. Both of those cells are haploid and in their union they form a diploid zygote. This is really important in keeping the specific genome of the particular specie. For example, each human has 46 chromosomes in each of their cells. That means they are diploid or 2n.These chromosomes are homologous and therefore form 23 pairs. Each reproductive cell has 23 chromosomes formed during gametogenesis, therefore they are haploid (n).  This makes it possible when fusing the sperm and the oocyte each with 23 chromosomes to create a 46 chromosome carrying cell – the zygote.

The fetal period includes the time between 9th week of pregnancy until birth. During fetal period cells, tissues and organs keep on differentiating, while the fetus gains weight and increases in size.

It has been proven that different factors can have an influence on prenatal development. More vulnerable to such effects is the stage of organogenesis, because this is the time where each organ forms. During fetal period organs keep on developing but their basic structure is already formed. Factors could have an effect during fetal period as well, but it would not be that strong as in organogenesis.


Why is Embryology important for us?
In the past embryology had more of an observing importance, rather than today where its knowledge is used to take care of different problems during pregnancy. Most of these problems have an impact on the postnatal development as well.  Many experiments and findings in other  sciences are extremely important in Embryology. They have fundamental importance in understanding each process that leads to the forming of a fetus.  Embryology gives us a chance to create better health care strategies, therefore there would be better outcomes in reproduction.  Having more and more knowledge makes it possible to have better techniques for prenatal diagnosis, treatments, solving the problems of infertility, preventing birth defects. A great percent of the abortions and child’s death is caused by birth defects. For example there is a type of numerical abnormality in chromosomes, where the fetus has 47 instead of 46 chromosomes. In such cases a particular pair of chromosomes has not two but three chromosomes. This is called trisomy. Trisomy 13is an abnormality where the fetus has three chromosomes of number 13. More than 90% of the children die before they were even given birth.

Tea – the second most common drink in the world

milica Articles, Diet Leave a comment   , , , ,

Tea is one easy to prepare type of drink, which especially with today’s technology could be made within minutes. It is the second most common drink in the world after water. This is for sure not by chance.

Why do people like tea?

The answer is quite simple – it is delicious. What is better than having a hot cup of nice, just prepared tea with a spoon of honey in it. The amazing aromatic scent of the tea even makes it a pleasure. There are so many different types of tea tastes – from fruits and flowers to mixtures of different herbs. There are so many people who do this on a daily basis and feel the power this kind of relaxation gives them.

Why is it good to drink tea every day?

Most of the people believe that tea dehydrates their bodies. Probably the reason for this is the sustaining of caffeine in it. Yes, taken in high doses it could lead to dehydration. However, the concentration of caffeine in tea is not that high and there is no such effect as dehydration of the body. Even doctors recommend to their patients when they have the flu to drink tea. It is a hot drink which would help for the throat but also would sum up to the necessary amount of liquid needed to be consumed daily. Especially while having a disease, drinking tea is extremely helpful. Yes, it is not a traditional medicine, but it has substances which are extremely important for the organism, for its normal processes and protection. This also proves that drinking tea daily could mean keeping your body healthy and protecting it from the antigens which could attack it.

Some of those substances are :

  • Polyphenols
  • Vitamin A
  • Vitamin E
  • Vitamin C

Polyphenols act as antioxidants in the body. These substances are really important of taking care of free radicals in the organism. Free radicals have a harmful effect on cells and tissues, therefore on the whole body as well. Vitamin A acts also as an antioxidant. Vitamin E is important for maintaining the health of the heart, as well for the structures in the skin. Vitamin C is important for keeping the resistance and immunity in the organism. It is extremely important for smokers, since nicotine decreases the amount of Vitamin C in the body, therefore it has a really bad effect on the whole state of the organism.

How many cups of tea should be taken for a healthy effect?

Even one cup of tea daily would be better than none. However, of course like any other substance, which people can intake, overdosing could mean harm. Usually the best amount is to drink four or five cups of tea daily. No more, no less than this.

Does tea have an effect on people who want to lose weight?

Tea has a major effect on the body’s metabolism. Metabolism is actually in guilt for putting on weight. If you have a slow metabolism, then even if you take the perfect amount of food substances daily this would not help to reduce weight. Usually normal pace of metabolism means a normal amount of food substances daily and keeping your permanent weight. Fast metabolism means even overeating sometimes would not have a large impact on your weight. There are certain diseases where metabolism slows down and this makes the people prone to putting on weight. Tea in such cases helps quite a lot to maintain a normal metabolism.

Other effects of tea

There are certain types of tea, which lead to the so called “tea drunk” state. People describe it to be similar to the alcohol buzz. Such type of tea for example is the Oolong.

Tea was proven to be useful for people – for their overall health and protection against diseases. It is good for hydration when taken in normal quantities. Do your body a favor and prepare a nice, hot cup of tea.


Trichomonas vaginalis

milica Articles, Parasitology 1 , ,

 

     Trichomonas vaginalis is a flagellated protozoan, which means it contains only of one cell, which has cytoplasma and nucleus, seperated from the outside world by a cell membrane.

The parasite has 4 flagella on the front end of the cell and one going vertically to the body. It differentiates the so called undulating membrane. The nucleus is situated in the front of the cell. On the opposite side of the undulating membrane, in the front end of the cell, there is a cytostome. A conspicuous barb-like axostyle projects opposite the four flagella, coming out from the back end of the cell. Its lenght is 7 to 30 micrometers. It has no cyst form but it is possible to live up to 24 hours in urine, semen or even water.

It does not have mitochondria and therefore the necessary enzymes and cytochromes in order to conduct oxidative phosphorylation. Therefore the needed proteins are transmitted throughout the cell membrane. Some of the needed substances are gothered by phagocytosis. The needed energy is acquired by anaerobic breaking of glucose to glycerol and succinate in the process of glycolisis.

This parasite is found in the vagina of  women and urethra of both men and women. It is one of the most common parasites on earth. The acidity in the vagina ( pH 5,9 to 6,5) makes it extremely enviramental-friendly for the parasite.

The way this parasite is transmitting is by sexual interaction. With men there is usually no signs of an infection. However, women experience in most cases symptoms such as a fluid, different in colour – from yellowish to greenish, called vaginal fluid. This is due to the infection of the vaginal wall, called colpitis, caused by the parasite.

T. vaginalis is also known to cause different complications such as low birth weight, preterm delivery, predisposing to HIV infection, cervical cancer. It is also found in the urinary tract, fallopian tubes and pelvis, as it can cause pneumonia, bronchitis and oral lesions.

Treatment is considered to be extremely hard but not impossible. Usually antibiotics are prescribed – metronidazole or tinidazole. Since it is really easy to be infected, again in most cases there is treatment provided for both sexual partners. Even though men experience most of the times no symptoms they are still transmitting the parasite to their sexual partners. Symptoms with men could be those of urethritis(purulent or clear discharge).

Using condoms in order to prevent transmitting this parasite reduces the chances of  doing so, but NOT completely.

 


Cola – one of the most unhealthy soft drinks

milica Articles, Diet Leave a comment   , , , , ,

For years Coca Cola company has been offering ones of the most well sold and demanded products on the market. Millions of people around the world have tried out drinking cola. Most of them even drink it on a daily basis. How many cans of cola do you drink per day? How about per week? Did you ever think about what is it that makes cola so wanted and addictive? In the past cola was produced using Cocaine. This is actually where the name of it started – Coke. As years followed, the manufacturers had to change their formula so that it fits the health requirements. Instead of Cocaine nowadays they use caffeine. However, the addictive and unhealthy effect is still present.

Let’s take a look at what the basic ingredients of a can of cola are:

  • Sugar ( approximately 10 teaspoons of sugar)
  • Carbonated water
  • Caffeine
  • Phosphoric acid

The sugar you observe with one can of cola is actually the amount you need for the whole day. This fast intake increases your blood sugar, making your pancreas produce more insulin in order to turn the additional sugar into fat. This reaction could be compared to the so called stress of the organism. Everything taken in greater quantities in the organism is extremely unhealthy. The reason that you do not vomit after taking in so much sugar at once is the presence of phosphoric acid in the cola.

The phosphoric acid binds important for the organism minerals – calcium, magnesium and zinc. Due to the caffeine there is an urge to urinate and because of that you release through your urine the water from the cola, together with the phosphoric acid that is bound to the important minerals. Just as an example those minerals are extremely important for healthy and hard bones. Magnesium is also really important for the cell organels that produce proteins. Calcium is also really important for muscle contractions. So instead of letting your organism use these minerals for essential needs, they are simply wasted with every can of cola.

The caffeine leads to increase in blood pressure and dilation of the pupils. The liver releases sugar in the blood and the receptors of adenosine in the brain are blocked. At the same time a higher amount of dopamine is produced in the body, which affects the pleasure receptors. This is how heroin affects the brain and causes addiction.

The effect does not last long and once it is gone there are different mental states such as irritation. Each can of cola has 140 calories, therefore it is even worse for people who are trying to lose weight.

Now try to imagine what it is like for your organism every time when you let yourself have a can of cola. Think about the mood change which it gives you after drinking it. One great favor to yourself that you can do is to quit drinking cola.
