Regular foot test for diabetic patients

Diabetic patients have greater risk of developing problems with their feet, due to the damage high blood sugar can cause to sensation and circulation.

Incurable foot ulcers or any injury can lead to amputation as a result of lack of sensitivity at that part of the body.

Diabetic patients must undergo annual check up, people should also perform the touch toes test to make sure their feet are still sensitive.

The test involves very lightly touching six toes, three on each foot to find out how many of the touches are felt. The touch must be gentle, light as a feather and brief.

If sensation is impaired you may not realise if minor damage has occurred and left untreated may increase the risk of infection.

Visit your doctor as soon as you discovered a cut or have any concerns about your foot and legs.

Where does blood come from?

Sweden scientists have discovered how the first blood cells form during human development as they change from endothelial cells to hematopoietic.

A laboratory model of human stem cell was developed, observing the expression of blood cell and endothelial cell genes in each individual cell, a progression from an endothelial state was found.

 Niel-Bjarne Woods, was in charge of the study, he said understanding how the first human blood cells develop will provide more information on how to generate blood stem cells for treatment of blood disorder.

Human blood is composed of several specialized cells for different purposes like providing oxygen and immune response against viruses and bacteria.

During embryonic development, the first stem cells form and leads to production of all the blood cells you will produce in your lifetime.

The cells changing to blood in the embryo begin as endothelial cells that make up the walls of the developing arteries. After sometime, it developed into tightly packed spindle shaped endothelial cells and later detach to form round cells of the blood and released into circulation.

Sudden hypotension may cause dementia

Blood pressure is the force of blood pushing against the wall of the arteries as the heart pumps out blood.

Hypotension is low blood pressure, particularly in the arteries of the systemic circulation.

Blood pressure naturally goes up and down all the time, adjusting to heart requirement based on daily activities.
Reading lower than 90 mm Hg systolic or 60 mm Hg diastolic is low blood pressure.

 Sudden drop in blood pressure can stop  blood flow to the  brain and this can cause severe decline in mental ability that interfere with daily life. People suffering from hypotension are at the risk of developing dementia.

 Shortage of  blood flowing to the brain can damage brain cells and this can disrupt cells communication in the brain.
