Patients with Alzheimer's Have Type 2 Diabetes, With Associated Increased Advanced Glycation End Products (AGEs) and Increased Expression of Receptor for AGEDs

 

Advanced Glycation End Products

Advanced glycation end products (AGEs) are lipid or protein materials that become highly glycated due to contact with sugars. They are a bio-marker implicated in aging and the development, or worsening, of many degenerative diseases, such as diabetes, atherosclerosis, chronic kidney disease, and Alzheimer's disease

They play an important role in the development and aging of both healthy and unhealthy cells, as well as in the occurrence and progression of several degenerative diseases. These include cirrhosis of the liver, fatty liver, and multiple sclerosis. They also cause the destruction of the red blood cell (RBC), the formation of advanced glycation end products or AME (products of glycation) inside the red blood cells and the premature aging of tissues. Most of these proteins are unstable and changes their function when exposed to varying sugars. This process can be triggered by a number of environmental factors, including obesity, chronic alcohol abuse, hormonal changes, insulin resistance, tobacco use, anti-inflammatory drugs, medications used in the treatment of cancer, and environmental toxins.

In recent years, there have been a number of new studies that have examined the effect of advanced glycation end products on the human body. These studies have revealed that excessive accumulation of unprocessed proteins in cells may be a contributing factor in diabetes, obesity, cardiovascular disease, osteoporosis, rheumatoid arthritis, Alzheimer's disease, stroke, and many degenerative diseases. Some of these diseases are associated with increased concentrations of unprocessed sugars in the blood, as well as elevated blood pH levels. It has been proposed that the excessive levels of glucose within the cells may be produced via the glycation of proteins, which then contribute to the pathogenesis of most degenerative diseases.

Damage-associated molecular pattern interaction with their central receptor, receptor for advanced glycation end products, has found to increase the risk of Covid-19 in obese/diabetic patients. In November 2020, vTv Therapeutics Inc., a U.S.-based clinical-stage biopharmaceutical company, reported baseline characteristics for the enrolled subjects in the ongoing Elevage clinical study of azeliragon as a potential treatment for mild Alzheimer’s disease in people with type 2 diabetes. Approximately 35% of patients with Alzheimer’s disease have type 2 diabetes, with associated increased advanced glycation end products and increased expression of the Receptor for Advanced Glycation End products, the target for azeliragon.

Bell shaped pepper is a member of the Capsicum Baccatum species, which includes the Ají pepper

Image
  Bell pepper is the normal name for a cultivar gathering of the species Capsicum annuum, generally developed for their consumable, bell-shaped natural products, which are described by a polished outside of various shadings, including red, yellow, green, and orange. Bell peppers are now and then gathered with less impactful pepper assortments of Capsicum annuum known as "sweet peppers." There additionally are assortments of C. annuum that are impactful or hot, like the cayenne and jalapeño peppers. Bell shaped peppers contain a latent quality that disposes of capsaisin, the alkaloid that causes "hotness" in different plants in the family Capsicum. With their perfectly shaped structure and strikingly shaded outside of assorted shadings, bell peppers have been classified "the Christmas decorations of the vegetable world," to which is added a crunchy surface and tart taste (GMF 2008). Expanding on the variety in nature, bell shaped peppers mirror the notew...

Light Linear Alpha Olefins Are Produces through Oligomerization of Ethylene and by Fischer-Tropsch Synthesis

Image
  Light linear alpha olefins are commonly manufactured by two main routes: oligomerization of ethylene and by Fischer-Tropsch synthesis followed by purification. They are manufactured for a variety of reasons. One such reason is to use them as fabric and other textile applications in clothing manufacture. Various companies use ethylene trimerization process that produces only 1-hexene. In the U.S., Chevron Phillips Chemical Company, LLC, uses this process. Another commercial process, offered by a technology licensor IFP, dimerizes ethylene to high purity 1-butene. There are a wide range of applications for light linear alpha olefins . They are predominantly use in production of polyethylene, linear aldehyde, fatty acids, linear alcohols. Alpha olefins are also used in production of synthetic lubricant basestock and to make surfactants in a blend with higher linear alpha olefins. Another common use of light linear alpha olefins includes printing and apparel industries, agricul...

How is Tissue Banking Beneficial to People with Severe Morbidity, Chronic Diseases, and Organ Transplant Surgery?

Image
  Tissue banking alludes to the movement of gathering, stockpiling, handling, and circulation of transplantable human tissues. This industry fills in as a store of disposed of tissue and organs, both legitimately and wrongfully. These organs are here and there taken from criminal bodies or the dead groups of lawbreakers. Some of the time they may come from individuals who kick the bucket in emergency clinics. Whatever they are, every one of the organs are normally taken to a focal tissue bank which at that point discards them as indicated by neighborhood enactment. This interaction of collecting organs happens both when passing. There are numerous elements that decide when organs come from dead bodies. The fundamental one is that the organ must be dead and not yet deteriorating. Numerous organs must be eliminated from individuals who have passed on of sicknesses and ailments as these organs are not, at this point valuable. Some are even too harmed to possibly be helpful any longe...
