Nervous System Development Overview The development of a single human fertilized egg into an individual is largely mysterious. In the process, the developmental central nervous system is the most complex. The central nervous system is formed by the ectoderm of the embryo. In the neuroblast stage, the notochord is the central axis of the embryo that runs through the embryo early and induces the undifferentiated ectodermal cells above it to transform into the primordium of the central nervous system. First, the dorsal ectoderm cells above the notochord are elongated and thickened to form a front wide and narrow nerve plate; the edge of the nerve plate is thickened and pleated to form a nerve pleat; the central plate of the nerve plate is concave to form a nerve groove. Then, the nerve pleat moves to the midline of the back and finally closes to form a neural tube. The anterior part of the neural tube develops into a brain, and the posterior part develops into a spinal cord. From this ... Continue reading →

With the continuous development of nanotechnology, gold nanoparticles are widely used in the field of medicine. Gold nanoparticles not only have good controllability, biocompatibility, and biosorption, but also have a high degree of stability, and can achieve specific biometrics and functions through surface modification. Therefore, it has become an important nanomaterial in biomedicine. The Role of Gold Nanoparticles Gold nanoparticles alias AuNPs and nano gold, their diameters are 1~100 nm. Gold nanoparticles are nano-sized particles of gold, and the powder is black or dark brown. The nano-gold solution is generally a sol dispersed in aqueous solution, so it is also called colloidal gold, water-soluble colloidal gold nanoparticles, and so on. The gold nanoparticles with different particle sizes show different colors. The color of colloidal gold is related to many factors. The colloidal gold with a small particle size (2-5nm) is yellow, the colloidal gold with a medium particle ... Continue reading →

Micelles refer to molecularly ordered aggregates that begin to form in large quantities after the surfactant concentration reaches a certain value in an aqueous solution. In micelles, the hydrophobic groups of surfactant molecules aggregate to form the core of the micelle, and the hydrophilic polar groups form the outer layer of the micelle. Liposomes are an artificial membrane. In the water, the hydrophilic head of the phospholipid molecule is inserted into the water, and the hydrophobic tail of the liposome extends into the air. After stirring, a spherical liposome with a double layer of lipid molecules is formed, with a diameter ranging from 25 to 1000 nm. Micelles and liposomes are both nanoscale carrier systems commonly used to improve drug delivery or cosmetic formulations. From their definitions, we can see that there are certain differences between the two. Differences in Structure and Composition Micelles: Micelles are tiny particles made of surfactant molecules (also called ... Continue reading →

Chemical Characterization is a powerful methodology for addressing biocompatibility endpoints, providing a risk assessment of biocompatibility using chemical, biocompatibility, and patient exposure data. Chemical Characterization involves the extraction of the device with various solvents, chemical analysis of compounds extracted from the device, and an evaluation of the toxicological risk associated with the patient exposure to the extracted compounds. Standard for Chemical Characterization "Chemical Characterization of materials", part eighteen of the Biological evaluation of medical devices standards (ISO 10993-18), gives out the general considerations for the analytical approach including the intended use of device contact time (blood, mucosal, skin contact), material composition, and surface area calculations. It also outlines for the extractables, the study design, solvents, temperature, and duration should be taken into account; while for the leachables, the drug ... Continue reading →

Rheumatoid arthritis (RA) is a chronic autoimmune condition that primarily affects the joints, causing inflammation, pain, and potential joint damage. Understanding the progression of RA involves recognizing the four stages that individuals may experience over time. Let's delve into what are the 4 stages of rheumatoid arthritis, shedding light on the evolving nature of rheumatoid arthritis. Stage 1: Early RA The initial stage of rheumatoid arthritis is often referred to as early RA. During this phase, individuals may experience joint pain, swelling, and stiffness. These symptoms typically manifest on both sides of the body and may initially affect smaller joints, such as those in the fingers and toes. Morning stiffness lasting more than 30 minutes is a common hallmark of early RA. At this stage, joint inflammation may not be readily apparent on imaging tests like X-rays, making the diagnosis challenging. However, blood tests measuring markers like rheumatoid factor (RF) and ... Continue reading →
