nsmission of a nerve IMPULSE along a NEURON from ONE end to the other occurs as a result of electrical CHANGES across the membrane of the neuron. The membrane of an unstimulated neuron is polarized—that is, there is a difference in electrical charge between the outside and inside of the membrane. The inside is negative with respect to the outside.Polarization is established by maintaining

What is a brain PET scan? A brain positron emission tomography (PET) scan is an imaging test that allows doctors to see how your brain is functioning. The scan captures images of the activity of the brain after radioactive “tracers” have been absorbed into the bloodstream. These tracers are “attached” to compounds like glucose (sugar). Glucose is the principal fuel of the brain. Active areas of the brain will be utilizing glucose at a higher rate than inactive areas. When highlighted under a PET scanner, it allows doctors to see how the brain is working and helps them detect any abnormalities. It’s typically an outpatient procedure. This means you’ll be able to GO about your day after the test is complete. Why is a brain PET scan performed? The test accurately details the size, shape, and function of the brain. Unlike other scans, a brain PET scan allows doctors a view of not only the structure of the brain, but how it’s functioning as well. This allows doctors to: check for cancer determine if cancer has spread to the brain diagnose dementias, including Alzheimer’s disease differentiate between Parkinson’s disease and other conditions prepare for epilepsy surgery Your doctor may have you undergo a brain PET scan regularly if you’re undergoing treatment for brain disorders. This can help them monitor the success of your treatment. How to prepare for a brain PET scan Your doctor will provide you with complete instructions to help you prepare for your brain PET scan. Alert your doctor to any medications you may be taking, whether they’re prescription, over the counter, or even nutritional supplements. You may be instructed not to eat anything for up to eight hours before your procedure. You will be able to drink water. Tell your doctor if you’re pregnant or believe you could be pregnant. The test MIGHT be unsafe for your fetus. You should ALSO tell your doctor about any medical conditions you may have. For example, people with diabetes will likely be given special instructions for the test. Fasting beforehand could negatively affect their blood sugar levels. Immediately before the test, you may be asked to change into a hospital gown and remove all of your jewelry. Of course, you want to plan your day around your appointment as well. How a brain PET scan is performed You’ll be brought into the procedure room and seated in a chair. A technician will insert an intravenous catheter (IV) into your arm. A special dye with radioactive tracers will be injected into your veins through this IV. Your body needs time to absorb the tracers as blood flows through the brain, so you’ll wait before the scan begins. This typically takes about an hour. Next, you’ll undergo the scan. This involves lying on a narrow table attached to the PET machine, which looks like a giant toilet paper roll. The table glides slowly and smoothly into the machine so the scan can be completed. The scans record brain activity as it’s happening. These can be RECORDED as video or as still images. The tracers are concentrated in areas of increased blood flow. When the desired images are stored in the computer, you’ll exit the machine. The test is then complete. Following up after a brain PET scan It’s a good idea to drink plenty of fluids after the test to help flush the tracers out of your system. Generally all tracers are out of your body after two days.  Meanwhile, a specialist trained in reading PET scans will interpret the images and share the information with your doctor. Your doctor will then go over the results at a follow-up appointment.   Explanation:The information provided for all radioisotopes includes: — Isotope; — Half-life; — Nuclear reactions; — Excitation function; — Bibliography.

When the exploration of Lake Whillans started in Antarctica, researchers did not expect to find much life. Constant subzero temperatures and lack of obvious sources of nutrients did not seem to be conditions that would support a thriving ECOSYSTEM. To their surprise, the samples retrieved from the lake showed abundant microbial life. In a different but equally harsh setting, bacteria grow at the bottom of the ocean in sea vents, where temperatures can reach 340 °C (700 °F). Microbes can be roughly classified according to the range of temperature at which they can grow. The growth rates are the highest at the optimum growth temperature for the organism. The lowest temperature at which the organism can survive and replicate is its minimum growth temperature. The highest temperature at which growth can occur is its maximum growth temperature. The following ranges of permissive growth temperatures are approximate only and can vary according to other environmental factors. Organisms categorized as mesophiles (“middle loving”) are adapted to moderate temperatures, with OPTIMAL growth temperatures ranging from room temperature (about 20 °C) to about 45 °C. As would be expected from the core temperature of the human BODY, 37 °C (98.6 °F), normal human microbiota and pathogens (e.g., E. coli, Salmonella spp., and Lactobacillus spp.) are mesophiles. Organisms called psychrotrophs, also known as psychrotolerant, prefer cooler environments, from a high temperature of 25 °C to refrigeration temperature about 4 °C. They are found in many natural environments in temperate climates. They are also responsible for the spoilage of refrigerated food. Explanation:Life in extreme environments raises fascinating questions about the adaptation of macromolecules and metabolic processes. Very low temperatures affect cells in many ways. Membranes lose their fluidity and are damaged by ice crystal formation. Chemical reactions and diffusion slow considerably. Proteins become too rigid to catalyze reactions and may undergo denaturation. At the opposite end of the temperature spectrum, HEAT denatures proteins and nucleic acids. Increased fluidity impairs metabolic processes in membranes. Some of the practical applications of the destructive effects of heat on microbes are sterilization by steam, pasteurization, and incineration of inoculating loops. Proteins in psychrophiles are, in general, rich in hydrophobic residues, display an increase in flexibility, and have a lower number of secondary stabilizing bonds when compared with homologous proteins from mesophiles. Antifreeze proteins and solutes that decrease the freezing temperature of the cytoplasm are common. The lipids in the membranes tend to be unsaturated to increase fluidity. Growth rates are much slower than those encountered at moderate temperatures. Under appropriate conditions, mesophiles and even thermophiles can survive freezing. Liquid cultures of bacteria are mixed with sterile glycerol solutions and frozen to −80 °C for long-term storage as stocks. Cultures can withstand freeze drying (lyophilization) and then be stored as powders in sealed ampules to be reconstituted with broth when needed.request; please make my ans brainly
