In order to be able to look at tissues under a microscope, we need to first stain them with the right technique. Learn the main staining techniques used in histology today on our full video: https://khub.me/aux9w

As you probably know, histology is the study of the microscopic anatomy of cells and tissues. So we use staining methods to visualize and distinguish the different parts of cells and tissues since cells and their structures are usually transparent or colorless. The types of dyes used to color cells and their components can either be specific to particular structures, chemical groups or even molecules, and it can also be non-specific in which case most of the cell is stained in the same way.

When staining tissue samples, dyes that are used are either acidic or basic or a combination of the two. And why is that, you might be asking. Well, cellular structures such as nucleic acids or proteins have charged groups which are known as phosphate groups or carboxyl groups, just to name a couple. The dyes used in histology are colored organic compounds which also have a charge. Acidic dyes carry a negative charge and so they bind to positively-charged cell structures.

In the full version of this tutorial, we will cover some of the most common types of dyes used in histological staining of cells and their structures:
- basic dyes vs acidic dyes vs neutral dyes;
- hematoxylin and eosin;
- PAS - staining;
- Golgi method;
- Toluidine blue;
- Masson's trichrome;
- Osmium tetroxide;

Alzheimer's and the Brain
Alzheimer's and the Brain samer kareem 1,470 Views • 3 years ago

Alzheimer’s disease is an irreversible, progressive brain disorder that slowly destroys memory and thinking skills, and eventually the ability to carry out the simplest tasks. In most people with Alzheimer’s, symptoms first appear in their mid-60s. Estimates vary, but experts suggest that more than 5 million Americans may have Alzheimer’s. Alzheimer's disease is currently ranked as the sixth leading cause of death in the United States, but recent estimates indicate that the disorder may rank third, just behind heart disease and cancer, as a cause of death for older people. Alzheimer’s is the most common cause of dementia among older adults. Dementia is the loss of cognitive functioning—thinking, remembering, and reasoning—and behavioral abilities to such an extent that it interferes with a person’s daily life and activities. Dementia ranges in severity from the mildest stage, when it is just beginning to affect a person’s functioning, to the most severe stage, when the person must depend completely on others for basic activities of daily living. The causes of dementia can vary, depending on the types of brain changes that may be taking place. Other dementias include Lewy body dementia, frontotemporal disorders, and vascular dementia. It is common for people to have mixed dementia—a combination of two or more disorders, at least one of which is dementia. For example, some people have both Alzheimer's disease and vascular dementia. Alzheimer’s disease is named after Dr. Alois Alzheimer. In 1906, Dr. Alzheimer noticed changes in the brain tissue of a woman who had died of an unusual mental illness. Her symptoms included memory loss, language problems, and unpredictable behavior. After she died, he examined her brain and found many abnormal clumps (now called amyloid plaques) and tangled bundles of fibers (now called neurofibrillary, or tau, tangles). These plaques and tangles in the brain are still considered some of the main features of Alzheimer’s disease. Another feature is the loss of connections between nerve cells (neurons) in the brain. Neurons transmit messages between different parts of the brain, and from the brain to muscles and organs in the body.

Stem Cell Injection Alternative to Surgery
Stem Cell Injection Alternative to Surgery samer kareem 5,539 Views • 3 years ago

Adult stem cells are cells from your own body that can renew themselves and turn into other cells (differentiate). They live inside all of us in various tissues, poised to leap into action to repair damage as it occurs. As we age or have big injuries, we may not be able to recruit enough of these cells to the site to fully repair the area. Regenexx Stem Cell Procedures help overcome this problem by extracting stem cells from an area of high volume, then concentrating the cells and reinjecting them into the damaged area to help the body heal naturally.

Reyes syndrome
Reyes syndrome samer kareem 2,090 Views • 3 years ago

In Reye's syndrome, a child's blood sugar level typically drops while the levels of ammonia and acidity in his or her blood rise. At the same time, the liver may swell and develop fatty deposits. Swelling may also occur in the brain, which can cause seizures, convulsions or loss of consciousness. The signs and symptoms of Reye's syndrome typically appear about three to five days after the onset of a viral infection, such as the flu (influenza) or chickenpox, or an upper respiratory infection, such as a cold

This form of liver cancer is called primary liver cancer. Noncancerous, or benign, liver tumors are common. They do not spread to other areas of the body, and they usually do not pose a serious health risk. In most cases, benign liver tumors are not detected because they cause no symptoms.

Severe combined immunodeficiency
Severe combined immunodeficiency samer kareem 1,756 Views • 3 years ago

Severe combined immunodeficiency (SCID) is a life-threatening syndrome of recurrent infections, diarrhea, dermatitis, and failure to thrive. It is the prototype of the primary immunodeficiency diseases and is caused by numerous molecular defects that lead to severe compromise in the number and function of T cells, B cells, and occasionally natural killer (NK) cells. Clinically, most patients present before age 3 months. Without intervention, SCID usually results in severe infection and death in children by age 2 years. A committee of experts, initially sponsored by the World Health Organization (WHO), meets every 2 years with the goal to classify the group of primary immunodeficiency diseases according to current understanding of the pathways that become defective in the immune system.[1] Eight classification groups have been determined, with SCID being one of the best studied. Over the past few decades, the diverse molecular genetic causes of SCID have been identified with progress from studies of the immune system.[2] SCID is considered a pediatric emergency because survival depends on expeditious stem cell reconstitution, usually by bone marrow transplantation (BMT). Appropriate diagnosis is essential because instituting proper treatment is lifesaving. Despite the heterogeneity in the pathogenesis of immune defects, common cutaneous manifestations and typical infections can provide clinical clues in diagnosing this pediatric emergency.[3] Skin manifestations were prevalent in primary immunodeficiency disorders studied in 128 pediatric patients in Kuwait; skin infections were the most prevalent findings, seen in 39 patients (30%), followed by dermatitis in 24 (19%).[4] Skin infections were significantly more prevalent in those with congenital defects in phagocyte number, function, or both, as well as in those with well-defined immunodeficiencies. Dermatitis was evident in all patients with hyper–immunoglobulin (Ig) E syndrome and Wiskott-Aldrich syndrome.[4] Erythroderma of infancy with diffuse alopecia was seen exclusively in patients with SCID disorders, and telangiectasia in patients with ataxia telangiectasia; and partial albinism with silvery gray hair was associated with Chediak-Higashi syndrome. With the advances in BMT and gene therapy, patients now have a better likelihood of developing a functional immune system in a previously lethal genetic disease. However, once an infant develops serious infections, intervention is rarely successful.

Patent ductus arteriosus (PDA)
Patent ductus arteriosus (PDA) samer kareem 1,918 Views • 3 years ago

Patent ductus arteriosus (PDA) is a persistent opening between two major blood vessels leading from the heart. The opening, called the ductus arteriosus, is a normal part of a baby's circulatory system before birth that usually closes shortly after birth. If it remains open, however, it's called a patent ductus arteriosus. A small patent ductus arteriosus often doesn't cause problems and might never need treatment. However, a large patent ductus arteriosus left untreated can allow poorly oxygenated blood to flow in the wrong direction, weakening the heart muscle and causing heart failure and other complications. Treatment options for a patent ductus arteriosus include monitoring, medications and closure by cardiac catheterization or surgery.
