Disadvantages Of Masspec Pens
Is a pen really mightier than the scalpel?
One of the most crucial aspects of cancer diagnosis and treatment is to determine the thin boundary between the lesional and normal tissues. So it is important to assess an accurate negative margin and to completely excise the tumor for a prolonged disease free state and increase the overall survival of the patient.
The conventional method for margin assessment is histopathological analysis which is labor-intensive, time-intensive and requires expertise. Another related method is the frozen section preparation which requires skilled technicians and pathologists. Though the technique is quite reliable, it has few disadvantages like freezing artefacts affecting the tissue structure and cell morphology. The intraoperative margin analysis increases the operating time and there is an

1: The operational steps of the MasSpec pen
MasSpec pen has been tested on 20 thin sections of human cancer thin and 253 tissue samples from human patients including normal tissues and cancerous tissues from ovary, breast, lung and thyroid.
It can obtain non-destructively a rich molecular information from tissue samples.
The MasSpec pen is capable of identifying histologically distinct regions in a single human tissue sample. These results show that the MasSpec pen can be used to detect cancer in margins with mixed composition of normal and cancer cells by the molecular information obtained.
Thus this recent technology in the diagnosis of cancer can be exploited for OSCC detection and diagnosis and assessment. It can be used intraoperatively also to assure the complete excision of cancerous tissue which will offer a prolonged disease-free state and increase the overall survival. Thus, the MasSpec pen, considering its performance, simple design and usage with clinically desirable features enable its use in clinics or primary health care centres for routine screening and diagnosis of OSCC leading to improved patient care and

Unit 3 G1
1153 Words | 5 PagesA laser hits the fluorescent colors to deliver light which is recognized by a confocal scanner. The scanner then creates a computerized picture from the energized microarray. The advanced picture is further handled by particular programming to change the picture of every spot to a numerical reading. The way toward measuring quality expression by means of cDNA is called expression analysis or expression profiling. By finding which genes in cancer cells are mutated, scientists can better analyze and treat growth.

Henrietta Lacks Informed Consent
976 Words | 4 PagesIn the late 1940s, scientific research began taking off as innovative technologies and diseases were being created and discovered. One important field of study during the time was cancer. Like many types of new research, there were a few problems getting the ball on the roll. One problem scientists faced was obtaining cancerous cells that would stay long enough to study. One scientist struggled with this until a particularly unique strand of cells came along.
Leaky Gut Syndrome Lab Report
528 Words | 3 PagesWhat To Know About Testing For Leaky Gut Syndrome Leaky gut syndrome, or LGS, causes a wide variety of symptoms such as skin rashes, brain fog, constipation, diarrhea, and food sensitivities. Since these symptoms are also caused by other medical conditions, it is often difficult to pinpoint leaky gut as the cause of your problems. If you suspect you have LGS, talk to your doctor about being tested. He or she may recommend the lactulose/mannitol urine test. Here is some information about how it works.

968 Words | 4 PagesNicholas Navin Laboratory. Where I helped his graduate student, Marco Leung in the research project “Investigating Cell Line Heterogeneity and Clonal Interaction in Breast and Colon Cancer Cell Line.” Understanding tumor heterogeneity and clonal interactions is of great importance in cancer research, because it can help in the development better diagnostic procedures and treatments for cancer patients. Dr. Navin increased my interest in cancer genetics, because thanks to him I learned more of the genetic processes involved in tumor development, tumor heterogeneity and metastasis. Additionally, under Dr. Navin’s mentoring I learn about cell culture, understanding heatmap and copy number profile.

Phulbotomy Research Paper
1499 Words | 6 PagesEver since we are little, most of us hate the idea of needle pricks at the doctor’s office. We cringe, cry, hold our moms hand or even embarrassingly pass out. Although we are difficult patients during the collection of blood specimens, it is actually crucially important for a Phlebotomist to perform a proper collection of specimens. Phlebotomy can be the backbone of the laboratory and provide proper diagnosis for patients. Improper collection can lead to complications, including misdiagnosis.
Skin Disease: Malignant Melanoma
719 Words | 3 PagesOther types of biopsy methods may be used such as wedge or punch biopsy, but these techniques tend to be less accurate. After the biopsy is performed a wide excision should follow. This should encompass a l good margin of healthy tissue. Any further excision will depend on the thickness of the tumor. Depending on the invasive ness of the tumor a lymph node biopsy might be conducted to see if any of the draining lymph nodes were affected (Hodgetts, 2013).

For diagnosing PMP as well as verifying the development of the disease, several tests are available. PMP can often be found during treatment of or operation performed for other medical problems. The selection of tests applicable to a particular patient as well as the frequency of the tests is discussed with a doctor. The tests vary depending on the symptoms that arise.

Cytopathology Personal Statement Examples
373 Words | 2 PagesMy interest in cytopathology sparked during my first month of pathology training when we were called for a parotid mass fine needle aspiration, it was a case of mammary analogue secretory carcinoma, seeing my attending describe the morphology of the cells to render that diagnosis, was not only inspiring but also exciting. Since that moment I waited eagerly for my first cytopathology rotation . I enjoyed every second of my cytology and FNA rotations where I was able to gain hands on experience performing FNAs, and I also realized how crucial is the patient interaction in this specialty for which my previous experience as a clinician gave me great advantage. Cytopathology is an extremely challenging field that pushes a diagnostician to integrate the clinical, morphologic and immunophenotypic features of each disease to reach the correct diagnosis.
