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;

Unborn Baby saved After Mother Is Wounded In Missile Strike in Syria
Unborn Baby saved After Mother Is Wounded In Missile Strike in Syria Surgeon 14,223 Views • 2 years ago

Doctors save the life of an unborn baby who was injured along with her mother in a missile attack in the Syrian city of Aleppo. The video shows a team of emergency medical workers delivering the baby by Cesarean section and then treating the newborn for the shrapnel wounds covering her body and one very large gash in her head. “Medics can be seen frantically reviving the baby, after delivering her by emergency cesarean, as she lies motionless,” the article states. “Eventually the tiny newborn begins to cry and seemingly comes to life as she is given an oxygen mask and rubbed vigorously.” “According to Reuters, the woman also has three other children, all of whom were injured in the attack, but are reported by doctors in the hospital to be in a good condition,” the Daily Mirror article states. The article does not provide the gestational age of the baby before it was delivered. The article said the pregnant woman was hit by a barrel bomb – “crude explosives and shrapnel and dropped from helicopters used by [Syrian] President Bashir al-Assad’s regime." The article notes an estimated 7.6 million Syrians have been displaced by the ongoing civil war and that 320,000, including 11,000 children, have been killed in the conflict. The Daily Mirror also reports that the doctors suggested that the tiny girl be named Amal, which means hope in Arabic.

Open heart (coronary artery bypass, or CABG) surgery is performed in order to reroute, or "bypass," blood around blocked arteries, thereby improving the supply of oxygen-rich blood to the heart. Surgeons usually use an artery from the chest wall to construct the "detour" around the blocked part of the artery. Veins from the legs are also used.
