Scientists discover Alzheimer’s hidden “death switch” in the brain

-
Image
A team led by neurobiologist Prof. Dr. Hilmar Bading at Heidelberg University has identified a key molecular process that drives the progression of Alzheimer's disease. Working with researchers from Shandong University (China), the scientists used a mouse model of Alzheimer's to show that a harmful protein interaction causes brain cells to die, leading to cognitive decline. The findings point to new possibilities for developing more effective treatments. The harmful protein interaction involves two components previously studied: the NMDA receptor and the TRPM4 ion channel. NMDA receptors play an essential role in communication between nerve cells and are located on the cell surface, both at synapses and in areas outside these junctions. They are activated by glutamate, a key neurotransmitter. When NMDA receptors function within synapses, they support neuron survival and help maintain cognitive function. However, when TRPM4 interacts with NMDA receptors outside synap...

Kenya coins replace leaders with animals

-
Image
copyright KENYA CENTRAL BANK Kenya has dropped the images of presidents from newly minted cash coins, in what is seen as an attempt to prevent their glorification. Previous coins bore the images of Kenya's three ex-rulers: Jomo Kenyatta, Daniel arap Moi and Mwai Kibaki. Many Kenyans saw this as an attempt by their leaders to promote themselves, and to personalise the state. The new ones have images of the country's famous wildlife, including lions, elephants, giraffes and rhinos. President Uhuru Kenyatta - the son of Kenya's first leader Jomo Kenyatta - said the new coins were a "big change" and showed "our nation has come a long way". All three of the incumbent's predecessors had their images printed on the currency during their rule. Mr Kibaki, who won elections in 2002 ending Mr Moi's 24-year rule, broke a promise not to have his image printed on money. copyrightGETTY IMAGES Notes with images of Kenya's founding leader Jomo Ken...

Sickle Cell Test

-
Image
1. Objective The objective of the Sickle Cell Test was to detect the presence of Hemoglobin S (HbS), which caused sickle cell disease or sickle cell trait. The test aimed to screen or diagnose individuals who inherited the mutated beta-globin gene. 2. Principle The principle of the test was based on the fact that Hemoglobin S polymerized under low oxygen tension, causing red blood cells to become crescent or sickle-shaped. These abnormally shaped cells were detected microscopically (sickling test), through solubility tests, or by electrophoresis to differentiate hemoglobin types. 3. Materials • Anticoagulated blood sample (EDTA) • Sodium metabisulfite (for sickling test) • Microscope and glass slides • Hemoglobin electrophoresis equipment (for confirmatory test) • Solubility test reagent kit (for rapid screening) • Coverslips • Test tubes and pipettes • Gloves and safety equipment 4. Procedure (Microscopic Sickling Test) 1. A drop of the patient’s blood was placed on a clea...
