Leading Cause Behind Allergies Essay

Monozygotic twins: Monozygotic twins are also known as identical twins. These twins start their life as one egg which is fertilized by one sperm and latter splits into two eggs much earlier in the gestational period. These are very rare and have no link to heredity. But studies reveal that only one of four conceptions of twins is identical. Therefore, it seems likely that any differences between twins will have to be caused by environment rather than by genetics.

Twins, share a bond that no parent, child or sibling relationship can ever compare. There are two main types of twins, and these include: monozygotic (identical) twins and dizygotic (fraternal) twins, and they are compared by their emotional, behavioural, and cognitive similarities. (Robert Plomin, 1997). According to Social Issues Referencing, 2007, whereas Identical twins are formed from a single (mono) zygote and are genetic “carbon copies”, fraternal twins develop from two (di) separate zygotes, as a result of two eggs being fertilized by two sperms independently. (Social Issues Referencing, 2007, para. 8)

Asthma is the most common worldwide chronic condition that affects both young and old. It is a condition in which the air way passages are narrowed leading to symptoms of wheezing, shortness of breath, chest tightness, and cough (Bijanzadeh, Mahesh, Nallur 1). Asthma is caused by increased infiltration of inflammatory cells into the airway, constriction, airway smooth-muscle hypertrophy, and mucous hypersecretion in the bronchiolar walls of the lung (Bijanzadeh, Mahesh, Nallur 1). Most asthma attacks are short, a few minutes to a few hours, and the person recovers completely this is called episodic asthma disease. However, those who have acute severe asthma is much more serious because the asthma attacks lasts for days or weeks, and

Twins can be either monozygotic or dizygotic. Monozygotic or identical twins develop from one zygote, which splits and forms two embryos. They are natural clones of each other and are genetically identical. There are three types of monozygotic twins that can form, that depends on early development in the fertilized ovum or embryo splits. The first type of monozygotic twins have separate amnions and chorions. About one-third of identical twins separate before the trophoblast forms on the fifth day. The second type of identical twins that share one chorion and one amnion. This type of split happens about one percent in monozygotic twins, because the tissue splits after these structures are already developed. The third type of twins that are monozygotic, share a chorion and a different amnion. This type of split occurs in about two-thirds of identical twins. Identical twins occur in about thirty percent of births in the world, although not all twins survive long enough to be born. Dizygotic or fraternal twins occur when two sperm fertilize two separate eggs. This usually occurs when two eggs are released from the ovaries and are fertilized. Dizygotic twins normally run in females in the

Allergic rhinitis is started by an allergic immune response to inhaled allergens. Atopic people have a genetic predisposition to become sensitised to harmless allergens. Dendritic cells which act as antigen-presenting cells capture the allergen and present allergenic peptide to T lymphocytes in lymph nodes. CD4+ T cells play an important role in starting and orchestration of the allergic immune response by secretion of cytokines such as interleukins 4, 5, 10, and 13. Interleukin 4 is fundamental cytokine in driving sensitisation to allergens. Interleukin 4 stimulatesthe IgE switch in B lymphocytes. After releasing of IgE into the bloodstream it binds to receptors on the surface of mast cells and basophils. When the patient exposure to the allergen and the allergen reach nasal mucosa of sensitised individuals, they bind allergen-specific IgE on the surface of mast cells, resulting in release of inflammatory mediators such as histamine.

Most parents think that they can control their children’s diet, but they cannot monitor everything their kids eat. Some kids are really sensitive with food and it can make them allergic. Especially with severe food allergies, it can be life-threatening.

Identical twins are twins resulting from the division of a single fertilized egg, which usually share a common chorion. Identical twins have the same DNA. another name for fraternal twins is dizygotic meaning that

Over the last thirty to forty years, the incidence of atopic diseases has increased. Atopic diseases are considered the “classic allergic” diseases like dermatitis, allergic rhinitis (hay fever) and asthma. Atopy is considered the ability to produce IgE (Immunoglobulin E, which is a type of antibody that can be found in small amounts in the body but plays a major role in allergic diseases) in response to common environmental proteins like house dust mites, grass pollen, and food allergens. This increase in diseases led to research into what may be the cause. Genetic predisposition is a key factor in one’s susceptibility to atopic diseases. However, researchers concluded that this particular increase had occurred in too short of a time frame

It is reported that some people characterize allergies as an immunity, “gone wrong” because they do not have the protective antibodies a normal person would carry if exposed to an allergen. The best way to overcome histamine is to avoid complete contact with the allergen (6). There is no official cure for histamine. However, people take medications to block the action of histamine, known as antihistamines. They control or inhibit allergy symptoms caused by foreign pathogens. Allergic reactions are reduced or stopped when antihistamine bind to the histamine receptors, therefore preventing histamine from connecting with those receptors (2). The history of antihistamines dates back to the 1930s when a notable researcher and professor studied drug

One of the primary ways to deal with allergies is to reduce your exposure to your triggers. That's impossible to do if you don't know what your triggers are. If you're allergic to just a few things, you might be able to avoid them most of the time so you won't be dependent on allergy medication. Your allergens might only be found in specific places or at certain times of the year. When you know when you're likely to be exposed, you can be prepared by having medication ready or by wearing a mask or taking other measures. You'll be able to manage your allergies much better when you know what will set off your symptoms.

Having an allergy is a hard thing you have to check labels, watch what you eat, make sure you don’t eat what you are allergic to just to make sure you don’t die. You do all that to not have a reaction to the food that you are allergic to. Having an allergy can happen to anyone and my aunt is one of those victims…Stephanie has an allergy to shellfish, and it didn’t happen till she was 24.

First, there are two common classifications of twins, either fraternal or identical. A fraternal twin is when there are two eggs that are fertilized by two separate sperm. Fraternal twins can be a boy and a girl, like my brother and I, as pictured on the left. They can be any combination of the two genders. What is really interesting about this type of twin is they can come from different fathers, which is known as superfecundation.

Main point: First let me start by telling you what the really meaning of twin is. The term "twins" actually comes from the ancient German word twin or twine meaning two together. There are identical twins, and fraternal twins. Identical twins mean that they develop from one zygote that splits and forms two embryos, or dizygotic or also known as fraternal, meaning that they develop from two eggs. A big thing that people do not understand is that twins can be two girls, two boys, or even a boy and a girl. Growing up I went to school many different sets of twins and none of us act the same so when we get asked what it is like to be a twin, we can only answer for our twin experience and not for everyone.

There are two types of twins. One type of twins, called identical twins, is exact clones of each other. They share the same DNA and were made from a single split egg. More research as been done regarding these types of twins as they are the more remarkable kind. Since they are a genetic match, nature plays the
