Stem cells are undifferentiated biological cells that can differentiate into specialized cells and can divide (through mitosis) to produce more stem cells. They are found in multicellular organisms. In mammals, there are two broad types of stem cells: embryonic stem cells, which are isolated from the inner cell mass of blastocysts, and adult stem cells, which are found in various tissues. In adult organisms, stem cells and progenitor cells act as a repair system for the body, replenishing adult tissues. In a developing embryo, stem cells can differentiate into all the specialized cells: ectoderm, endoderm, and mesoderm while also maintaining the normal turnover of regenerative organs, such as blood, skin, or intestinal tissues.
Above: Why Do Brazilians Speak Portuguese And Not Spanish?
Unlike other Latin American countries, Brazil’s official language is Portuguese, not Spanish. So what led to the country’s different language?
Brazil, is the largest country in both South America and Latin America. As the world’s fifth largest country by both area and population, it is the largest country to have Portuguese as an official language and the only country in the Americas. Bounded by the Atlantic Ocean on the east, Brazil has a coastline of 7,491 km (4,655 mi). Brazil borders all other South American countries except Ecuador and Chile and covers approximately 47.3% of the continent’s land area. Brazil’s Amazon River basin includes a vast tropical forest, home to diverse wildlife, a variety of ecological systems, and extensive natural resources spanning numerous protected habitats. This unique environmental heritage makes Brazil the subject of significant global interest and debate regarding deforestation and environmental protection.
Glaucoma is a leading cause of blindness worldwide. Vision loss from glaucoma occurs when axons in the optic nerve become damaged and can no longer carry visual information to the brain.
Glaucoma is most often treated by lowering pressure in the eye with drugs, laser surgery, or traditional surgery. However, these treatments can only preserve remaining vision; they don’t improve or restore vision that has already been lost due to glaucoma.
Why Is Vision Loss In Glaucoma Permanent?
The nervous system is divided into the peripheral and the central systems. Damaged peripheral nerves, in your arm for example, can regenerate after injury. However, the optic nerve and the spinal cord are in the central nervous system and unfortunately cannot regenerate after injury. This is why vision loss from glaucoma, like paralysis from spinal cord injury, is permanent. The unique cellular environment of nerve cells in the central nervous system may be why regeneration is prevented.
Angola is officially known as the Republic of Angola and is a country in Southern Africa. It is the seventh largest country in Africa, and is bordered by Namibia to the south, the Democratic Republic of the Congo to the north, Zambia to the east, and the Atlantic Ocean to west. The capital and largest city is Luanda.
The standard of living in Angola remains low for the majority of the population, and life expectancy and infant mortality rates in Angola are among the worst in the world. In addition, the majority of the wealth in Angola is concentrated in a disproportionately small sector of the population.
Angola currently has over 24.3 million people that span various tribal groups, customs, and traditions. The official language of Angola is Portuguese due to the fact that it was a Portuguese colony until 1975 (that same year Angola descended into an intense civil war that lasted until 2002). Angola is currently the deadliest place in the world for kids and the most dangerous country in Africa for children.
What Is Leukemia?
Leukemia is a cancer of blood forming tissues, hindering the ability of the body to fight infection.
Leukemia is rare compared to other diseases of the body.
Leukemia affects approximately 20,000 to 200,000 people in the United States per year.
Leukemia always requires lab tests or imaging of the cells, tissues, and organs of the body.
Leukemia requires a medical diagnosis from a doctor or medical professional.
Leukemia is treatable by a doctor or medical professional.
Symptoms of Leukemia
Many patients with slow growing types of leukemia do not have symptoms. Rapidly growing types of leukemia may cause symptoms that include fatigue, weight loss, frequent infections, and easy bleeding or bruising.
People With Leukemia May Experience:
1) Pain in the bone or joints.
2) Whole body chills, dizziness, fatigue, fever, nausea, night sweats, weakness, or sweating.
3) Gastrointestinal symptoms such as blood in stool or diarrhea.
4) Skin rashes or red spots.
5) Common symptoms also include bleeding, easy bruising, headache, mouth ulcer, nosebleed, shortness of breath, swelling, swollen lymph nodes, or unintentional weight loss.
Leukemia Is Treatable By A Doctor Or Medical Professional
Treatment for Leukemia is highly variable. For slow growing types of leukemia, treatment may include monitoring. For aggressive types of leukemia, treatment may include chemotherapy that is sometimes followed by radiation and stem cell transplants.
