Research project Essay Example | Topics and Well Written Essays - 750 words

Research project - Essay Example To prove the effectiveness of the instrument, the researchers collected the blood sample from a donor and tested it. They measured the diameters of the white and the red blood cells, and they got accurate values. Additionally, they measure the quantities of different blood components, and they got accurate values too (Optical society of America, 2012). The devices work through the Spectrally Encoded Confocal Microscopy (SECM). Through this technique, the images are formed after the split of light beams to form a line of purple to red colors. When scanning a person’s blood, a probe is placed close to the person’s skin. The red to purple line is then directed towards the blood vessels. When the blood cells pass the line, they split it into scattered colors forming images (Optical society of America, 2012). The technique is advantageous over other blood scan systems, since it does not rely on the complicated equipments and harmful fluorescent dyes. However, the researchers discovered that one of the challenges of using this technology is the difficulties in finding the blood vessels depths (Optical society of America, 2012). 2. The use of optical microscopy in studying the blood characteristics will make the work of the medical experts easier. In the paper, the researchers have demonstrated the viability of the Spectrally Encoded Flow Cytometry (SEFC). ... They compared the SEFC imaging using the in vivo, and the in Vitro imaging system. The researchers used Healthy volunteers who pressed their lower lips against the probe of the in vivo imaging. For the in vitro imaging, blood was collected from the healthy donors using venipuncture. The results showed that the SEFC in vivo imaging system produce clearer images compared to the in vitro imaging system (Golan, Yeheskely-Hayon & Minai, 2012). This is because it was possible to see and count even the smallest capillaries. Additionally, more images were observable in the in vivo imaging system. However, while using the in vivo system, the researchers experienced some challenges while trying to find the image depths (Golan, Yeheskely-Hayon & Minai, 2012). Through the study, the researchers discovered that the SEFC in vivo can show the characteristics of people’s blood components and the technique is non-invasive (Golan, Yeheskely-Hayon & Minai, 2012). The use of SEFC will be helpful in tracking the hematocrit levels, which is useful when studying the circulation alterations before and after surgeries (Golan, Yeheskely-Hayon & Minai, 2012). The study highlights the effectiveness of SEFC in visualizing cell deformation especially for those patients with sickle cell anemia. However, the researchers suggested that additional studies regarding the potential of the in vivo SEFC are necessary. This is because an upgrade in system is necessary to increase the imaging depth (Golan, Yeheskely-Hayon & Minai, 2012). 3 I All the articles demonstrate the potential of the SEFC in carrying out blood tests. The authors of both articles criticize the technology, and they think that further research is

Concussion Essay Example | Topics and Well Written Essays - 250 words

Concussion - Essay Example This can either cause a direct injury to the brain to produce swelling or formation of a hematoma (blood clot) that compress over different brain structures (Starkey, 2013). Concussion may or may not be associated with loss of consciousness. Other symptoms include nausea, vomiting, headache, unsteady gait, photophobia, retrograde amnesia and disorientation of other neurological functions. There are four grading of concussion depending on signs and symptoms of the patient (Barry, Dillingham and McGuire, 2002). When the severity of damage to the brain tissue is more, patient presents with more deteriorating signs and symptoms and graded high on the grading scale. Management and rehabilitation plan also depends on the severity or grading and the frequency of head injury. As injury is internal, much focus is on rest during rehabilitation process for healing. Sport players are asked to abstain from contact activities to prevent any superimposed injury that can result in â€Å"second impact syndrome† (Barry, Dillingham and McGuire,
