How many cells are held within one sheath of Gloeocapsa? If all human body cells have the same DNA molecules with the same genes, then what accounts for differences in cell types (red blood cells, skin cells, nerve cells, muscle cells, etc.)? If all human body cells have...
an iron containing molecule that is responsible for binding oxygen. Each red blood cell can contain over 250 million molecules of hemoglobin which also gives the cells their red color. Red blood cells are created in the bone marrow through a process known as erythropoiesis, which takes on averag...
Most substances that pass the intestinal barrier pass through a cell, not around it. These cells, then, selectively carry certain molecules across the barrier into the body while blocking passage of other substances. On the other side of the cells (now inside the body), in the lamina propria...
Consuming ultra-processed foods that are typically high in salt, sugar, and fat—and cheap and accessible—may boost the risk of heart disease, diabetes, anxiety, depression, and cognitive decline.
Atherosclerosis is the root cause of many cardiovascular diseases. Extensive research in preclinical models and emerging evidence in humans have established the crucial roles of the innate and adaptive immune systems in driving atherosclerosis-associated
Molecules in urine and blood can reveal how much of a person’s diet comes from ultra-processed foods, according to a study published inPLOS Medicinetoday1. The paper suggests that these measurements provide an objective way to track consumption of ultra-processed food — and would be useful ...
These properties are important in detecting ethanol in a sample by infrared (IR) spectroscopy. Read More Types of Devices: Intoxilyzer Diagram of the Intoxilyzer This device uses infrared (IR) spectroscopy, which identifies molecules based on the way they absorb IR light. Molecules...
Indeed, as with neuroactive metabolites, cell wall components of microorganisms in the intestinal lumen or attached to epithelial cells are poised to induce epithelial cells to release molecules that in turn modulate neural signaling or that act directly on primary afferent axons. 3. Colonization of ...
of proteins, but also the structures of DNA, RNA and other molecules, such as ligands. Crucially, this update will allow researchers to better predict and study how different molecules in the human body geometrically interact with each other—and anticip...
At the cellular level, medical illustrators must understand how to usemicroscopy techniquesin order to find references for accurate depictions of cellular structures. Objects at the smallest scale — atoms and many molecules — are smaller than the wavelength of visible light. This means they arebel...
