Ultrasound treatment was done according to method by [21] with some modifications. Ultrasonic probe (JY92-IIN, Ningbo Scientz Biotechnology Co. Ltd, Ningbo, China) was used, with maximum power 1000Watt, frequency 25 kHz and probe diameter of 13mm. Pectin solutions were treated at 60% duty cycles, sonication times was fixed at 20 minutes, sonication power (200 and 400 watts). Effect of acidity on sonication was determined at pH 2, 4 and 6, by adjusting solution pH using acetic acid. Native pectin 0.25g was put in 250ml beaker suspended in 100ml deionized water to achieve low viscosity, it was stirred on a magnetic stirrer for 30 minutes, and sonic treatment was done by immersing sonic probe up to 1cm deep in the solution. After treatment, the suspension was precipitated with equal volume of 95%v/v ethanol to precipitate pectin. The content was centrifuged at 7500xg and filtrate removed. the precipitate was left in fume cupboard to remove ethanol traces then re-dissolved in deionized water and frozen at -45ᴼC and eventually freeze dried for further analysis. Ultrasound intensity was predicted according to the following equation
I=P/(πr^2 )
Where I= intensity, r =radius of the sonic probe and P= ultrasonic power. 4.2.5. Molecular weight determination
The effect of sonication on pectin molecular weight was evaluated on HPSEC according to the method described by [36,37]. The analysis was carried out on a HPSEC system equipped with a Light scattering instrument (DAWN Heleos,
The primary focus of a Diagnostic Medical Sonographer is to create images by using a high-tech instrument which will take images from inside the human body that will be used by doctors to make a medical diagnosis (Society of Diagnostic Medical Sonography, 2015).
I want to be part of the Ultrasound program because I realized that where I’m from people don’t consider going into a major like this. I was raised to become a doctor or a nurse it was either of those or your family will be disappointed. I looked at how many doctors and nurses my community has but rarely any ultrasound technicians. I also like to travel to different parts of the world and I would love to have those skills as a ultrasound technician to help those women who are unable to afford to go to a clinic to see if their baby is in good condition. A woman should never have to choose between making a decision about losing her kid, I want to be able to help those women that are struggling daily whether their baby has a health condition or even letting the parents know their baby gender.
An ultrasound is also referred to as a sonogram. It uses a high frequency sound waves to create images of the inside of the body.
Heart beating fast, adrenaline flowing, and pressure in the air, is what one would expect in a career in a medical field; extremely demanding yet very rewarding and fulfilling. When working in a health care profession, patients often place their trust in a health care stranger’s hands to determine their diagnosis and to establish a treatment strategy. According to the Journal of Diagnostic Medical Sonography, a diagnostic medical sonographer is an individual who provides patient care services utilizing ultrasound and related diagnostic procedures. In addition, the Journal of Diagnostic Medical Sonography states a diagnostic medical sonographer is a multi-specialty profession comprised of many diverse emerging clinical areas (Bendick, P.
When I tell a person that I want to pursue a degree in Diagnostic Medical Ultrasound their first thought is babies. Which I don’t blame them because that is the part of ultrasound we are exposed most too. But ultrasound is so much more than just seeing an unborn baby. There are so many amazing things that ultrasounds can do. DMU is an imaging technique used to visualize the tissue structures/internal organs of the body by recording the returning reflections of ultrasonic waves with the purpose of pathology diagnosis. There are two names it goes by, ultrasound and sonography. These two terms are often used interchangeably. Ultrasound uses sound and acoustics to produce images that are then reflected back in real time.
Pancreatic duct is dilated in region of the head and neck of the pancreas measuring up to 7 mm, nonspecific. Negative for discreet mass on this noncontrast exam. Negative for parapancreatic inflammation. Unenhanced pancreatic parenchyma otherwise appears unremarkable.
, on the other hand, polymer concentration had negative correlation with sonolysis. Sweet potato pectin posseed good antioxidant activity which was enhanced by sonication process. Moreover, this research showed the potential application of ultrasonic in pectin depolymerization, which could also be applied in other polymers. Further study should be carried out to elucidate the degraded pectin materials composition and structure, its potential applications in plant protection, antimicrobial, anticancer, prebiotic
The Life of an Ultrasound Tech Ultrasound technicians, also known as sonographers, play a very important role in the medical field. One must be skillfully trained and strong-willed to pursue such a career. This career can either be extremely rewarding or stressful and troubling, depending upon the workplace you choose to perform in. There are many ups and downs to the job that should be considered before diving into the world of sonography. Before actually becoming a diagnostic medical sonographer, some education and training is required.
Diagnostic Medical Sonographer program matches my intelligence for several different reasons. The Anatomy and Physiology of the human body intrigues me just thinking about how the different organs, bones, and systems work. My deep interest in this area is one of the many reasons I decided to pursue a career in this field.
Ever since I had been a little girl, I have had a love for people and caring for them. I like to study them to figure out how and what they are feeling. If something is wrong, I enjoy problem solving to find ways to fix the situation or at least make the person feel better. I am also fond of watching people develop and grow, which is why when I bumped into ultrasound sonography, I fell in love.
Pregnancy is a beautiful time in a woman’s life. A mother waits nine long months to meet their bundle of joy they created with their partner. A mother can feel their belly grow, the baby move, and can even feel tiny sensations like hiccups. What a mother can’t do is actually see their little bundle of joy without having an ultrasound preformed. This paper will go over a brief history of obstetric ultrasound along with a slight explanation of why they are performed and include the benefits along with the possible risks of the procedure.
When someone hears the word “ultrasound” the first thing that one thinks of is probably a baby. People think of the black and white little image that shows the fetus for the first time. It’s fascinating to think that a small machine can process out a live image of the inside of a woman womb. Having the ability to get an image of a growing fetus was not always possible. It wasn’t until the mid-1950’s that obstetric ultrasound was introduced. (add reference) Before this woman had to struggle not knowing anything about their developing child. There was no way for them to find out the estimate age of the pregnancy, administer the growth, or the wellbeing of the fetus. Now in the 21st century ultrasound for pregnant woman is a common procedure they are required to get done. With this image modality, a woman can have an administer pregnancy during the nine months it takes for the fetus to develop.
Ultrasound is a therapeutic modality that uses vibrations which are produced mechanically at a higher frequency than sound waves. These waves are referred to as ultrasonic as they are unable to be heard by humans (Robertson et al, 2006). The success of the use of ultrasound has been recorded as early as the 1930’s, when in Berlin, sciatica in patients had been shown to have improved greatly. This evidently resulted in further research and new treatment methods being created (Stanley, 1958). Since then a lot of research has been carried out and advances in the use of ultrasound has been made and are continuing to be made all the time. The effects of ultrasound in rehabilitation will be researched and examined to understand its effectiveness.
I felt excited every week because I like hand on experience on patient at same I know that I gain my knowledge through clinical. Every unique clinical experience, every particular lab, and every clinical simulation help me. I watched a mammogram, ultrasound, and CT scans as usually. I like to watch more in mammogram and CT than ultrasound because ultrasound it is completing and hard to understand. Now that I know I take every x-ray exam and even take the patient to their room when the tech was busy. One time I was taking chest XR on hyper asthenic patient, and first I raise the tube in order to some light on the shoulder. Since the patient board chest, I cut off the costphrenic angle, then I take another cassette crosswise to get the rest of
Ultrasound or ultrasonography is a medical imaging technique that uses high frequency sound waves. It is a high pitch frequency that cannot be heard by the human ear. In ultra sound the following happens: High frequency sound pulses (1-5megahertz) are transmitted from the ultrasound machine into your body using a probe. The sound wave will travel into your body until it hits an object such as soft tissue and bone. When the sound wave hits these objects some of the wave will be reflected back to the probe. While some waves may carry on further till they hit another object and then reflected back. The probe picks up these reflected sound waves and relays them to the machine. The distance and time from the probe,
