Lipopolysaccharides, or LPS, refer to large molecules, which consist of a lipid and a polysaccharide joined together by a covalent bond. They are located in the outer membrane of the Gram-negative bacteria. As it is, they act as endotoxins, apart from extracting strong immune responses in case of animals.

Also known as lipoglycans, Lipopolysaccharides are an important component, located in the outer membrane of Gram-negative bacteria, playing a vital role in the structural integrity of the bacteria, as well as protecting the membrane from a few chemical attacks as well. Lipopolysaccharides also improves upon, the negative charge of the cell membrane part from helping in stabilizing the entire membrane structure.

As a matter of fact, it is of vital importance for gram negative bacterial cells, resulting in death, in case it is mutated or removed. Lipopolysaccharide is an endotoxin and hence is able to draw a strong response from usual animal immune systems. As it is, a Lipopolysaccharides challenge in case of immunology refers to the exposure of a subject to a Lipopolysaccharide that might act as a toxin. It comprises of three parts:

1. Lipid A

Lipid A consists of unusual fatty acids and is implanted into the outer membrane, whereas, the rest of the lipopolysaccharides projects from the surface. Lipid A resembles a disaccharide with several fatty acid tails, which reach out to the membrane.

2. Core oligosaccharide

Core oligosaccharide consists of unusual sugars like KDO, keto-deoxyoctulosonate and heptose. As it is, the core oligosaccharide is attached with lipid A, which is also responsible for the toxicity of gram-negative bacteria.

3. O-antigen

The O-antigen of the bacteria refers to the polysaccharide side chain. O side chain is also a polysaccharide chain, which arise from the core polysaccharide. The constitution of the O side chain undergoes variation between different Gram-negative bacterial strains. As it is, O chains decide whether the Lipopolysaccharides is considered rough or smooth. Entire length O-chains would make the Lipopolysaccharides smooth; whereas, the reduction of O-chains would result in the Lipopolysaccharides getting rough.

Lipopolysaccharide has been subject to experimental research for many years, mainly because of its role in activation of many transcription factors. It also produces several types of mediators, which are involved in case of septic shock.

Cystic Fibrosis or mucoviscidosis, as it is also known as, is a hereditary disease, which affects the exocrine glands of the lungs, pancreas, intestines, and liver, resulting in progressive disability caused due to multisystem failure.

Frequent lung infections are caused due to thick mucus production. Along with that a lower secretion of pancreatic enzymes is the main reason behind greasy stools, poor growth, as well as deficiency in fat-soluble vitamins.

Apart from that, males with cystic fibrosis can be rendered infertile as a result of congenital bilateral absence of the vas deferens. Quite often symptoms of Cystic Fibrosis may show up during infancy, as well as childhood. Meconium ileus is a common feature among newborn babies with Cystic Fibrosis.

Patients, suffering from Cystic Fibrosis may be diagnosed prior to birth by way of genetic testing. As it is, newborn screening tests are becoming more and more common. The prognosis of Cystic Fibrosis may be confirmed in case of detection of high levels of salt in a sweat test. However, some false positives may also occur.

A sad aspect of this condition is the unavailability of a cure. Due to this reason, most patients suffering from cystic fibrosis die at a very young age, most of them between the age group of 20 to 30 years of age, due to lung failure. As it is, according to a rough estimate, the average life expectancy for a person suffering from Cystic Fibrosis is said to be 37 years. However, things are not that gloomy as they used to be a few years ago. Today, the availability of several new treatments, as brought around a welcome change, with the life expectancy of a patient suffering from Cystic Fibrosis increasing by a large margin.

Cystic fibrosis is believed to be one of the most common life threatening genetic diseases. Lung transplantation becomes necessary in many situations, as Cystic Fibrosis gets worsened. In the United States, 1 in 4,000 children is believed to be born with born with this condition. As it is, Cystic Fibrosis is caused due to a mutation in the gene, cystic fibrosis transmembrane conductance regulator.

This results in the production of a chloride ion channel, which is important in the creation of sweat, digestive juices, as well as mucus. In most of the cases, people without Cystic Fibrosis have two working copies of the cystic fibrosis transmembrane conductance regulator gene, only one is needed to prevent cystic fibrosis. Development of Cystic Fibrosis takes place when neither allele can produce a functional cystic fibrosis transmembrane conductance regulator protein. It is due to this reason that Cystic Fibrosis is believed to be an autosomal recessive disease.

A hiatus hernia refers to a medical condition marked by a protuberance on the upper part of the stomach in the thorax, due to a tear or weakness in the diaphragm. Also know as hiatal hernia, the condition is marked by symptoms, which include acid reflux, along with pain, which is quite similar to heartburn, in the chest, as well as upper stomach.

In most of the cases, patients with hiatus hernias tend to show no symptoms as such. As it is, many a time, patients tend to experience heartburn, along with regurgitation. This happens as stomach acid refluxes back into the esophagus.

Various factors increase the risk of hiatus hernia. Factors like heavy lifting or frequent bending, frequent or hard coughing, hard sneezing, pregnancy and delivery, violent vomiting, straining with constipation, obesity, as well as use of the sitting position for defecation; might lead to Hiatus hernia. This is because, such activities, lead to n increased pressure within the abdomen. Other factors, which can cause hiatus hernia, include heredity factors, smoking, as well as stress.

Diagnosis in case of hiatus hernia commonly involves an upper GI series or endoscopy. As it is, hiatus hernia can be categorized under two categories, which are as follows:

1. Sliding hiatus hernia it is the most common form of hiatus hernia and counts for more than ninety percent of the cases. In this condition, the gastro-esophageal junction tends to move above the diaphragm along with some of the stomach.
2. Rolling Hiatus hernia is the second and the less common type of Hiatus hernia. In this condition, a part of the stomach projects through the esophageal hiatus and stays along the esophagus. This happens without any movement of the gastro-esophageal junction.

As it is, most patients with hiatus hernia suffer from no discomfort and hence no treatment is required as such. However, in case the hiatal hernia has taken up a large shape, or if is of the paraesophageal type, then it is expected to cause esophageal stricture and discomfort. As it is, symptomatic patients are required to raise the head of their beds. They are also required to avoid lying down directly after meals. Such measures need to be taken, until treatment is being rendered. In case if the condition has been caused due to stress, then in that case, stress reduction techniques might be prescribed. In case of obesity, weight loss therapy might be indicated. Apart from that, medications that focus on reducing the lower esophageal sphincter pressure need to be avoided as well.

Anti-secretory drugs like proton pump inhibitors may also be used for reducing acid secretion.

A genetic disorder refers to an illness which is a result of abnormalities in genes or chromosomes. There are some diseases, which are partly caused due to a genetic disorder, while environmental factors may also be involved. Most of the disorders are very much rare and may affect one person in every several thousands or even millions.

A few type of recessive gene disorder present an advantage in the heterozygous state in case of certain environments. As it is, a haploid cell is available with only a single set of chromosomes. A diploid cell consists of two sets of chromosomes. In case of human, the somatic cells are diploid, whereas the gametes are haploid.

Genetic diseases are typically diagnosed and treated by geneticists. Genetic counselors assist the physicians and directly counsel patients.

In cases where the disorder is caused by a single mutated gene, the disorder can be passed over to following generations in many ways. Uni-parental disomy, as well as Genomic imprinting may however affect the inheritance patterns. As it is, the distinction between recessive and dominant types are not always generalized, although the distinctions between autosomal and X-linked types can be generalized. This is because the autosomal and X-linked types are distinguished purely on the basis of the chromosomal location of the gene.

Sickle-cell anemia is also believed to be a recessive condition, however, heterozygous carriers feature increased immunity towards malaria in case of early childhood, which may be suggested as a related dominant condition.

Genetic disorders can also be multi-factorial or polygenic. This means that they are probably linked with the effects of multiple genes in association with lifestyle, as well as environmental factors.
Common Multi-factoral disorders include heart disease, diabetes etc. Usually, complex disorders would cluster in families. However, they do not have any specialized pattern of inheritance, thereby making it difficult to evaluate the risk of a person inheriting or passing on such disorders. Also, complex genetic disorders are difficult to study, as well as treat, as the specific factors that are responsible for most of these disorders are still unidentified.

Disorders caused due to multi-factorial genetic disorder, include asthma, autism, autoimmune diseases such as multiple sclerosis, cancers, cleft palate, diabetes, heart disease, hypertension, inflammatory, bowel disease, mental retardation, as well as obesity.

As it is genetic disorders are disorders, which may or may not be visible. As it is, genetic disorders have often been responsible for a number of premature deaths. It is a sad aspect, that our knowledge in this regard is still so much insufficient.

Menkes’ disease, or kinky hair disease, is also known as Menkes kinky hair syndrome. It is a disorder which affects the copper levels in the body, causing a deficiency of copper in the body. As it is, copper is an essential mineral for the body and intake in limited quantities is very much necessary for the health of an individual. The condition was first described in 1962, by Menkes.

The disorder is featured by thin and coarse hair, low levels of growth, as well as damage to the nervous system. As it is, Menkes syndrome normally strikes during infancy. As it is, major symptoms of Menkes disease involve weak muscle tone, seizures, sagging facial features, mental retardation, as well as developmental delay. Other symptoms include metaphyseal widening and brittle hair. In some cases, the symptoms begin to show later in childhood and are often less severe.

Menkes syndrome is said to be caused by mutations in the ATP7A gene. Due to this mutation in the ATP7A gene, copper gets poorly distributed to all the cells in the body. As a result, unusual copper accumulation takes place in some tissues and specific organs, such as the small intestine, or the kidneys. At the same time, the brain along with other tissue has to be content with unusually low levels of copper. Due to this reduced supply of copper, there is a reduction in the activity of several copper-containing enzymes, which are necessary for the proper structure and functioning of vital parts of the body, such as skin, hair, bone, blood vessels and the nervous system.

As it is, Menkes disease is an X-linked recessive disorder. Due to this reason, it is found to be substantially more common in males, as females need two defective alleles to get affected by this disease. Another disorder, which is known as occipital horn syndrome may also be found. As it is, occipital horn syndrome is a mild form of Menkes syndrome and occurs in early to middle childhood. It is featured by unusual calcium deposits in a bone at the base of the skull, coarse hair, as well as loose skin and joints.

In most cases, symptoms of Menkes syndrome show up during infancy and are mainly due to abnormal absorption copper in the intestine with secondary deficiency in copper-dependent mitochondrial enzymes. For two to three months, normal or trivially slowed development may follow. As the disease would progress severe developmental delay, along with a loss of early developmental skills would proceed. Along with that, there may be extensive neuro-degeneration in vital parts of the brain. Another effect of it can be that, arteries inside the brain can be coiled with tattered and split inner walls, which may cause rupture or blockage of the arteries. As a result of weak bones fractures might be common as well.

As it is, urine homovanillic acid/vanillylmandelic acid ratio has been projected as a feasible screening method, for earlier detection of the disease. As far as treatment is concerned, early treatment by way of intravenous or subcutaneous injections of copper supplements may be quite effective.

Hyperalgesia is a condition, which is denoted by an increased sensitivity to pain that might be caused due to damage to peripheral nerves or nociceptors. Temporary increment of sensitivity towards pain may also be caused as part of sickness behavior, or the response to infection.

As it is, hyperalgesia can be felt in discrete, focal areas, or as a more diffuse, body-wide form. Studies have revealed the possibility to experience a learned hyperalgesia of the latter form. The focal form is usually linked with injury, and is divided into two subtypes, i.e. Primary hyperalgesia and the Secondary hyperalgesia.

Hyperalgesia is believed to be induced by platelet-activating factor which comes about as an inflammatory, as well as an allergic response. This suggestively occurs through immune cells, which interact with the peripheral nervous system and releases pain inducing chemicals.
Long-term opioid use for the treatment of chronic pain, may result in opioid-induced hyperalgesia. Several studies of humans and animals have revealed that primary, as well as secondary hyperalgesia may develop in reaction to both chronic as well as acute exposure to opioids.  Such a side effect can lead to discontinuation of opioid treatment.

In case, where hyperalgesia has been caused due to chronic high doses of opioids, reduction in the dosage may cause an improved pain management. However, just like other types of nerve dysfunction, which are associated pain, the treatment of hyperalgesia may also be clinically challenging. As it is, in such situations, finding a proper drug or drug combination, which is effective in case of a particular patient might require a certain degree of trial and error.

Hyperalgesia is quite similar to other types of pain, which is associated with nerve damage, like allodynia, as well as neuropathic pain. consequently it might react to standard treatment for such conditions, by way of using several drugs such as non-steroidal anti-inflammatory drugs, glucocorticoids, tricyclic antidepressants, gabapentin, or atypical opioids such as tramadol.

As it is, stimulation of pain fibers along a pattern, which is consistent with that from inflammation changes on a form of amplification in the spinal cord, as long term potentiating. This usually occurs where the pain fibers synapse to pain pathway, which is the periaqueductal grey. Amplification in the spinal cord might therefore be another way of producing hyperalgesia.

As it is, one unusual cause of focal hyperalgesia is believed to be platypus venom. The release of pro-inflammatory cytokines activated leukocytes, which are triggered by endotoxins, lipo-polysaccharides, as well as other signals of infection, may also be a major cause of Hyperalgesia.

Neuralgia or neuropathic pain refers to as non-nociceptive pain. Neuralgia is a pain, which is caused due to a change in neurological function or structure. As it is, Neuralgia exists without any continuous nociceptive input. The condition was first recognized by Weir Mitchell, who was a Civil War surgeon.

It is said that he made extensive study in this regard, when he observed hyperalgesia and chronic pain in case of his patients, who were having nerve lesions in the extremities, along with certain cases where no lesions were observed. He termed the condition as causalgia which has since then been known as Complex Regional Pain Syndrome Type 1 and Type 2, where Type 1 denotes a condition in which no clear nerve injury is present, while Type 2 denotes a case in which nerve damage is clear.

Neuralgia can be categorized under two categories, i.e. central Neuralgia and peripheral Neuralgia. This abnormal pain has been believed to be associated to four possible mechanisms, i.e. ion gate malfunctions, the nerve becomes mechanically sensitive, cross signals between large and small fibers; and malfunction caused due to damage in the central processor.

It is quite difficult to diagnose Neuralgia and most treatments tend to show little or no effectiveness. As far as diagnosis is concerned, it usually involves location of the damaged nerve byway of identification of the missing sensory or motor function. It might involve tests like a nerve conduction test, or an EMG test. As it is, Neuralgia is far more complex to treat than other cases of pain, as it does not respond adequately to normal pain medications.

As it is, special medications tend to become more specific in case to Neuralgia and usually fall under the group of membrane stabilizing drugs or antidepressants like Lyrica, Neurontin and Cymbalta. Now, while in most cases, patients did not respond well to surgical treatments, in some cases, neural augmentative surgeries have shown some success.

As it is, Neuralgia is a form of chronic pain, which can be extremely hard to diagnose. A major reason for this is the fact, that Neuralgia is a very rare disease. It is worth mentioning that, women are more likely to be affected than men, especially those over 50, who are at a greatest risk. In some of the cases, multiple sclerosis has been linked to nerve damage, resulting in pain. Therefore, doctors are likely to ask about family history in order to help in diagnosis. As it is, nothing unusual is visible in brain scans; therefore diagnosis is generally based on the description of the symptoms and the responsiveness to the medication process.

Heart disease is actually a very wide term and is a term, which is often used to describe a variety of different diseases, which affect the heart. As a matter of fact, it is one of the leading causes of deaths, all across the world. It is estimated to cause on an average one death every 34 seconds in the United States alone.

As explained earlier, heart disease is a term which is used for denoting a number of diseases. The following are a few major types o disease, which are covered under heart disease:

1. Coronary heart disease
Coronary artery disease refers to a disease of the artery, which is caused due to the accumulation of atheromatous plaques along the walls of the arteries, which supply the myocardium. Myocardial infarction or heart attack and angina pectoris or chest pain are major symptoms of conditions which are caused due to coronary heart disease. According a rough estimate, more than four hundred and fifty thousand people die due to coronary heart disease every year in America.

2. Cardiomyopathy
Cardiomyopathy refers to the deterioration of the function of the myocardium, or the actual heart muscle, which may be caused due to any reason. People with cardiomyopathy are quite often subject to the risk of arrhythmia, as well as sudden cardiac death.

3. Cardiovascular disease
Cardiovascular disease refers to any disease, which affect the heart itself, along with the blood vessel system; particularly the veins as well as the arteries linked to the heart. Extensive studies in regard to disease dimorphism reveal that women suffering from cardiovascular disease generally suffer from types which affect the blood vessels; whereas in case of men, they normally suffer from types that affect the heart muscle itself. Common causes of cardiovascular diseases are hypertension, hypercholesterolemia, diabetes mellitus and hyperhomocysteinemia.

4. Heart failure
Heart failure, or congestive heart failure refers to a condition that can be caused due to any structural, as well as functional cardiac disorder, which impairs the capacity of the heart to fill with or pump a sufficient amount of blood throughout the body, thereby leading to the heart, as well as body’s failure.

5. Hypertensive heart disease
Hypertensive heart disease refers to a heart disease, which is caused due to high blood pressure, particularly localized high blood pressure. As it is, hypertensive heart disease, leads to Congestive heart failure, Coronary heart disease, left ventricular hypertrophy, Hypertensive cardiomyopathy and Cardiac arrhythmias.

Heart diseases are often caused due to obesity. Apart from that, smoking is also a major factor, which substantially increases the risk of heart diseases.

Thermoception is the sense by which the human body perceives the temperature. You can easily understand that what its importance is. In fact I must say that this is the most important property of the body of any organism. If something goes wrong in this process then what is going to happen you can easily understand. I must say that sometimes you will feel too hot and sometimes you will feel too cold. In fact your whole metabolism becomes weak. And I must say that the thermoception  is really the most important thing you will ever come across.

A particularly specialized form of the thermoception is used by the crotalinae and boide. They really show a very advanced form of protection. The sensors indirectly detect infrared radiation by its heating effect on the skin inside the pit. They can work out which part of the pit is hottest, and therefore the direction of the heat source, which could be a warm-blooded prey animal. By combining information from both pits, the snake can also estimate the distance of the object.

I must say that this disease can be very lethal. Suppose it’s a summer seasons then you must know that your skin filters out the heat and you feel better. But if you are suffering from this disease then you will definitely feel lots more heat than it actually wood be.

The major symptom of the thermoception is the extreme heat or extreme cold. In fact your immunity towards the heat will die and I must say that you will start feeling a lot more problem in maintaining the body heat.

As far as the cure is concerned I must say that you will definitely find it to be very quiet curable. There are many reasons for you not to worry about this disease. I must say that you will just have to take one capsule a day and you will soon get the result. I must say that the disease when found first was really a very big worry but as the time passed by I must say that the scientists were able to find its cure.

At present I must say that the disease just requires a little medication and you will feel a lot safer. The thermoception really look like incurable but I must say that it is quiet curable. However you should really take some precautions. They are as follows:

1. Don’t go out in the heat without sunscreen. I really feel that it could really be very dangerous for you.
2. Take bath regularly.
3. Try to avoid dust affecting your skin.

There are many more precautions which you will have to take but these are the most important one.

Wilson’s thyroid syndrome, or Wilson’s temperature syndrome, as it is also known as; is a condition, marked by low thyroid function. This condition was first addressed in 1990, by E. Denis Wilson, M.D., of Longwood, Florida. Although, Mr. Wilson, also came up with a medicinal cure for this condition; the cure has not been recognized by the American Thyroid Association.

Wilson’s Thyroid syndrome shows symptoms, which are similar to low thyroid function, like headaches, fatigue, fluid retention, hair loss, irritability, decreased memory, depression, unhealthy nails, as well as easy weight gain. Apart from that, there are several other symptoms, which are shown by a patient suffering from Wilson’s thyroid syndrome. In fact, it is said, that the syndrome can show, virtually every symptom that one can think of. It is also propagated as one of the most widespread of all chronic diseases and in all probability is responsible for a greater toll than by any other medical condition or disease.

According to Mr. Dennis Wilson, in most cases, where patients show signs of low thyroid function; the condition is not a result of improper secretion of thyroid hormone, caused by a glandular dysfunction of the thyroid gland. It is instead, a result of a block in the alteration of the less active form of thyroid hormone to a more active form, i.e. from T4 to T3. It is also said to be caused by a viable reticence of the action of T3 on body cells, as a result of high levels of its inactive mirror image, also known as reverse T3. It is relatively common for this syndrome, to strike rather suddenly and is said to be triggered by factors, such as pregnancy, stress, excessive production of estrogen and deficiency of progesterone.

Many dissimilar symptoms have been associated with low thyroid function Now, low thyroid function used to be a condition, which was diagnosed on the basis of the symptoms, along with the cholesterol levels. That was before the arrival of blood tests for thyroid hormone. It was only after the introduction of the thyroid blood tests, that doctors included these tests into the diagnosis procedure of hypothyroidism i.e. impairment of the thyroid gland itself.

Another big name in this field has been that of Broda Otto Barnes, who is considered to be a torch bearer in the analysis of the thyroid gland. Barnes has made notable contribution in this field since the 1940s. It was he who argued that low thyroid function is often subject to under diagnosis, as well as misdiagnosis. So, the cases, which are not detected in blood thyroid hormone levels, are often identified by low body temperatures. According to him, low thyroid symptoms were caused due to hypothyroidism.

However, the American Thyroid Association, which is a professional organization, has maintained its stance in regard to Wilson’s Thyroid Syndrome. It also issued a Statement on Wilson’s Syndrome, suggesting that it has not found any scientific evidence in this regard that could support the existence of this syndrome. Dr. Wilson continues to do his research in this direction and has garnered support from many quarters.
