Scientists from Northwestern University in the United States have discovered what may be the weakness of the SARS-CoV-2 virus, responsible for the development of Covid-19. Each discovery comes down to the electrostatics generated between the virus and the cells of the human body. Researchers believe that it is possible to take advantage of this weakness to help fight the new coronavirus.
The process works as follows: in electrostatics, opposite charges attract each other and similar charges repel each other. This also happens between us and the virus, because our cells are negatively charged and the virus, in a region located only ten nanometers from the part of the spiny protein that invades human cells, is positively charged. Exactly this point, so hidden, is considered possibly vulnerable by scientists.
To test the theory and give hope to the world, which has for the most part suffered from the pandemic caused by Covid 19, scholars have blocked the region with a negatively charged molecule. And to the general joy of the nation, the procedure prevented the new coronavirus from reaching the host cell.
Still, according to scientists, although it is good news, a way to combat the root disease, transforming this molecule into a real treatment, available to people all over the planet, will be a long and difficult job.
Gums make gels like gelatin (which is derived mostly from pork and beef hides), and gums help to prevent ice crystals in ice cream and frozen foods. They also help retain moisture in foods so that they stay fresher longer.
You will find gums in cream cheese to help control what we in the industry call syneresis. That’s what people outside the industry call “the cheese is leaking water all over the bagel”. There are hundreds of more uses for gums. For example, they help make instant products instant, help cigar wrappers stay wrapped, keep the herbs and spices nicely suspended in your salad dressings, and much much more.
Some non-food industry uses include:
- Paper sizing
- Art work (marbleizing paper and gloss on paper works)
- Oil well drilling
- Cosmetic bases
- Mummification (not a great source of income for us any longer)
Gums are called hydrocolloids. Just a fancy name for stuff that is soluble in water. Chewing gum (chicle), by the way, is not a gum, it is a resin. It is insoluble in water, that’s why it doesn’t melt in your mouth.
- Hydro = Water
- Colloid = Dispersion of small particles in another medium
They are too small to be seen under an ordinary microscope and are too large to pass through a semi permeable membrane.
Where do they come from?
Geographically speaking, gums come from all over the world from the land and the sea. There are five primary sources of gums:
Names like guar gum, locust (carob) bean gum and other lesser known gums. These gums are similar to wheat in that they are the center (endosperm) of a seed. Locust bean gum, despite its name, does not come from insects but rather from the seed of the carob pod. Many people know carob as the natural health food store substitute for chocolate. The outside shell is made into carob powder and the inside of the seed becomes locust bean gum. Guar, unlike flour or corn starch, does not need to be heated to get thick, a big advantage in processing some foods.
Exudates is a fancy name for sap, like maple syrup. The difference between maple syrup and gums like gum arabic (acacia gum), karaya (that’s the stuff that holds your dentures in, by the way), gum ghatti and gum tragacanth is that these saps harden as they ooze from the tree. The hardened sap is picked off the tree and ground down to a fine flour. Each has its own unique attributes. Gum arabic is used extensively in flavor emulsions … most every soda you drink started off with an oil emulsion that has gum arabic in it.
Seaweed, the same stuff they wrap sushi in. You’ll see names like carrageenan, alginate, and agar-agar (sometimes called agar by those trying to be overly familiar with the weed). Some of the marine gums form gels, such as gellan gum. Agar is the stuff you put in petri dishes to grow mold in science class. Get some seaweed next time you’re at the beach, boil it and dry the stuff that comes to the top. Grind it and it is a carrageenan, alginate, etc. depending on the plant with which you started.
This may sound a little like laboratory grown, but then what is wine, vinegar, yogurt, Swiss cheese, champagne or brie? They are essentially foods modified by microbes. Xanthan gum for example (pronounced zanthan) is manufactured using a natural (microbial) fermentation process which converts corn syrup to Xanthan Gum using the microorganisim Xanthomonas campestris. This microbe (commonly found on green leaves such as cabbage) produces the Xanthan Gum as a protective coating. Xanthan Gum is used extensively in salad dressings and many other products.
Are you looking for a general dental office in Brisbane? It is important to differentiate between dentists who are in general practice and others who perform cosmetic dentistry and other specialized procedures. There is a huge difference between these two different types of dentistry. Understanding such differences will allow you, the patient, to make the proper selection of the dentist needed for the type of work you need.
A general dentist office in Brisbane will perform the most basic of dental care procedures. This means the office will perform checkups on your teeth while also performing the common cleaning procedure needed to reduce the potential for tooth decay and cavities from developing. Today, you can search for general dentistry in Brisbane online using search engines and on social media, as you can see from this Brisbane general dentistry Instagram profile.
Of course, if you do suffer from a cavity, a dentist will do what is needed to drill through the cavity, remove the decay and deliver the fillings needed to restore or improve the condition of the tooth.
In some cases, the condition will be so bad that a root canal may be required. While not a basic procedure, this is not a very difficult one to perform. Root canal is a procedure that all general dentists can perform. It is not something that you consider to be enjoyable but you are generally expected to recover from it shortly after the procedure is done.
Far too often, people will not visit their dentist at regularly scheduled intervals. This is a huge mistake because it can lead to a bad situation getting worse. This would mean more work would be required because the problem was not given attention when it was just starting. Why make a bad situation worse when getting a basic checkup would eliminate such problems?
The inguinal hernia is the escape of bowels from the normal site through a hernial gate appearing in the pelvic area. In common opinion, the inguinal hernia is a trivial problem, since it is often treated with a routine intervention, in day hospital or outpatient. But frequently the inguinal hernia is annoying, often disabling and even fatal if strangled and untreated.
It is also calculated that 10% of the hernia already treated are relapsing. Considering that the number of interventions exceeds 100,000 per year, the social cost of this process is transparent, furthermore, during pre-surgery for recurrence, the risk of lesion of the testicular vessels increases.
The inguinal hernia is, therefore, not to be underestimated. In medicine, the issue is very much felt, so much to lead to the development of well over 80 methods to solve the problem satisfactorily.
What Is the Inguinal Hernia?
The inguinal hernia is the escape, at the level of the groin and precisely in the direction of the so-called inguinal canal, of an abdominal bowel. In general, the abdominal bowel that is the protagonist of the inguinal hernia is the intestine; more rarely, it is the bladder or a portion of adipose tissue located close to the abdominal organs bordering the inguinal canal.
Inguinal Hernia: How Common Is It?
Among the various types of hernia ( disc, Hiatal, crural, umbilical, diaphragmatic, etc.), the inguinal hernia is the most widespread by far (between 70 and 80% of all episodes of hernia are cases of hernia inguinal).
Men suffer the most: according to some estimates, the male population, compared to the female one, would be 7 to 10 times more at risk of developing an inguinal hernia. The inguinal hernia is typical of middle-aged adults, but it can also occur in children and the elderly.
In most cases, the inguinal hernia appears on the right side of the human body; more rarely, it forms on the left or both sides (bilateral inguinal hernia ).
Where Is the Inguinal Hernia?
The inguinal hernia is formed in the anatomical point where the inguinal canal resides; as the name suggests, the inguinal canal resides at the groin level, i.e. in the border space between the abdomen and lower limbs.
Not all inguinal hernias are detectable in the same position within the confines of the groin; the exact location, moreover, varies depending on where the abdominal bowel reaches inside the inguinal canal, once it has come out.
Hiatal hernia (as described in the Medscape article ), as such, does not cause particular disturbances but creates the conditions for the development of other pathologies.
The initial symptoms may be similar to those of esophagitis: intense salivation, hoarseness, repeated belching, especially after large meals, feeling of weight in the stomach, acid regurgitation, intense and persistent burning behind the sternum (retrosternal heartburn).
Sometimes the pain radiates from the stomach (epigastric area) to the neck and back between the shoulder blades, so much so that, in intensity and duration, it can be completely similar to the pain of heart origin such as an anginal crisis. In particular, these symptoms can worsen during intense exertion or during pregnancy, situations that increase intra-abdominal pressure.
Typical is the aggravation of symptoms when assuming the horizontal position or leaning forward, as when tying shoes. Image showing hiatal hernia seen with radiography simplifying the symptoms they can be divided into three categories: digestive, cardiorespiratory and general.
Difficulty indigestion, regurgitation, belching, retrosternal burning. In some cases, there may be constipation, diarrhoea, pain in the mouth of the stomach (epigastric site) and, more rarely, vomiting.
Dyspnoea (laboured breathing), a sudden change in heart rate which slows (bradycardia) or accelerates (night tachycardia), pain in the heart area (angina pectoris), dizziness.
Anaemia due to gastric malabsorption of iron or due to lesions of the gastroesophageal mucosa that causes bleeding (blood loss).
The severity of the symptoms varies according to the type and size of the hernia. Often, precisely because of the multiplicity of symptoms, when you have a stomach ache or digestion is severe, you tend to blame the hiatal hernia.
But it’s not always his fault. Hiatal hernia usually does not cause severe pain which can instead be caused by other pathologies, such as a peptic ulcer or even heart disease.
When you suffer from pain in the upper part of the stomach or poor digestion, you should not immediately blame your hiatal hernia, but instead go to the doctor for a thorough check-up.
