INTRODUCTION Figure 1: Molecular Structure of PET PET (or PETE) is also known as polyethylene terephthalate or (C10H8O4)n. Its natural state is a colorless, semi-crystalline resin when combined with other materials like glass fiber or carbon nanotubes, it increases the material’s strength. Polyethylene terephthalate melts at 260°C and Amorphous density (at 25oC) is 1.33 g/cm3. PET can be produced by 2 different reactions as a product of polymerization. The first reaction is between ethylene glycol
organism demands the search for novel candidates from plant-based sources. H. pylori infection is associated with a decreased risk of some other cancers, including gastric cardia cancer (cancer in the top portion of the stomach) and esophageal adenocarcinoma. However, these therapies have several inherent problems, including the appearance of resistance to the antibiotics used and associated adverse effects, the risk of re infection and the high cost of
esophagus, the squamous mucosa, is damaged by stomach acid and replaced with a metaplastic columnar mucosa, which results, symptomatically, in heartburn, indigestion, and chronic cough. Barrett’s Esophagus, in rare cases, can lead to esophageal adenocarcinoma. Research of this cancer link are still in early phases. There are no precise precursors known
A woman is said to be the light bulb in a family but what happens if she is unable to fulfill her roles and duties as a mother? Can we still say that a family stays happy when there is a lack of mother figure? One of the global health issues that mainly attacks women today is cervical cancer, a type of cancer that occurs in the cervix (a female reproductive organ that connects the lower part of a woman’s uterus to her vagina). Experts said that about 250, 000 women around the globe die of cervical
proctocolectomy and ileal pouch – anal anastomosis. Pathological examination of the resected specimen revealed a moderately differentiated adenocarcinoma in addition to numerous polyps which were villous, tubulo-villous and tubular adenomata with low grade dysplasia. There were oligocryptal and flat adenomata as well. The patient was diagnosed to have colonic adenocarcinoma complicating Gardner
Having a book written by a well known author about eating disorders could potentially be an indicator that this mental illness is becoming more well known and accepted into society. The book Wintergirls by Laurie Halse Anderson demonstrates, in fiction, possible side effects of severe eating disorders. The main character, Lia, has no friends left because Anorexia and purging has consumed her life, her best friend recently died due to a ruptured esophagus due to complications brought on by Bulimia
precursor to esophageal cancer (Lao-Sirieix, P., & Fitzgerald, R. C. , 2010). Around 1% of human cancers start in the esophagus — and only 19% of patients with esophageal cancer survive for five years after diagnosis , making it a serious condition. Adenocarcinoma originates in glandular cells — cells that produce fluids, such as mucus (National Cancer Institute, 2017). The cytosponge has the potential to replace endoscopies
includes glandular cell, which involves atypical glandular cells (AGCs), such as atypical endocervical or endometrial cells specified or not otherwise specified (NOS); atypical endocervical or glandular cells-AGCs that favor neoplastic; adenocarcinoma in situ; and adenocarcinoma (Bickley & Szilagyi, 2013). The third interpretation/result category is other, and can include endometrial cells in older women (Cash & Glass, 2014) or malignant neoplasms which are rare (Bickley & Szilagyi, 2013). Common causes
types of lung cancer, small cell and non-small cell, and each is treated differently. Doctors say about nine out of ten cases of all lung cancers are the non-small cell type, which is broken down into three categories: squamous cell carcinoma, adenocarcinoma, and large cell undifferentiated carcinoma. While many people have preconceived notions about lung cancer symptoms, it actually depends on the type of cancer a person has. Squamous cell lung cancer, which is more common in men, attacks near the
Reproductive system cancers.By Aaron Brophy There are many different types of cancers and each cancer has different origins, for example nervous system cancers originate in the nervous system.The different forms of cancers also have different treatments which are effective for that specific type but may make other cancers progress more for example proton therapy only works on cancers that have tumors with defined borders.however Reproductive cancers are cancers that affect the reproductive system
There are many types of cancers in the world. Each and every one of them has their own origin, for example, reproductive cancers, which can be in both males and females. In men there are multiple types of reproductive cancers. One of them is known as prostate cancer, which is located in the prostate and is a small walnut-shape that produces seminal fluid that nourishes and transports sperm, according to Fig.1 (Mayo Foundation, 2015). It is a common cancer in men and can develop in three different
Intruduction Salivary duct carcinoma (SDC) is an uncommon, extremely aggressive malignancy arising from the ductal epithelium of salivary glands. Salivary duct carcinoma is an inaccurate name for this entity because other salivary tumors are also of excretory or terminal ductal origin. It was originally reported by Oscar Kleinsasser in 1968 as Speichelgangcarcinome. SDC has been also termed cribiform salivary carcinoma of excretory ducts, intraductal carcinoma, and infiltrating salivary duct carcinoma
well as in the exocrine cells. Pancreatic tumors are clinically significant because some have an extremely poor prognosis and some produce serious clinical symptoms (4). The most common and lethal form of pancreatic cancer is pancreatic ductal adenocarcinoma (PDA). It originates in the exocrine region of the pancreas. PDA is the fourth leading cause of cancer death, ranking only behind lung cancer, colorectal cancer, and breast cancer.(4) At the time of diagnosis, 85–90% of patients have inoperable
mucocutaneous bleeding is an evidence of DIC. Disseminated intravascular coagulation has acute and chronic phases. In acute phase, a patient will have severe symptoms while in chronic phase a patient may suffer from inflammation of blood vessels or adenocarcinoma. DIC started by activating the coagulation factors at any stage in the pathway. First step in the pathway started by activating the thrombin, which then
Most cystic lesions of the major salivary gland are cystic neoplasms. Benign cysts are epithelial lined cavities usually containing fluid or semisolid material, incidence is 2-5%. Benign cysts of the salivary gland are classified into three types: a) Lymphoepithelial cysts b) Salivary duct cysts c) Dysgenetic cysts[28] a) Lymphoepithelial cyst Bernier and Bhaskar introduced the term lymphoepithelial cysts to stress that it is not an embryologic remnant. Lymphoepithelial cysts are considered distinct
consumption are methods of preventing the disease (MSKCC,n.d; NCI, 2013). Figure 1 shows an example of where SCC occurs within the esophagus. Esophageal cancer also appears in the glands lining the lower part of the esophagus, a condition called adenocarcinoma (AC), and is sometimes attributed to acid reflux, or the upward flow of acid into the esophagus from the stomach (NCI, 2013). Extreme levels of acid reflux may be a symptom of a severe condition called Barrett’s esophagus, a condition causing
Cancer is not one disease, but it is a large group of almost 100 diseases. It is characterized by uncontrolled growth of the cells in the human body and by the ability of these cells to migrate from the original site and spread to other sites. If cancer spread is not controlled, it may leads to death. Normal cells divide into new cells, then die in an orderly fashion. During the first years of a person’s life, normal cells divide faster, and after becoming an adult, cells divide to
Cells go through a process called mitosis in order to divide and produce more cells. When cells go through mitosis, the DNA replicates and the cell divides in two separate daughter cells. The cells will go through five stages when they divide; interphase, prophase, metaphase, anaphase and telophase. The regulation of cell growth is not constant and is determined by feedback from the cell. Cells may reproduce because of cell growth, cell replacement or regeneration. When a cell must reproduce, it
ABSTRACT Minor salivary gland neoplasms of the buccal mucosa are relatively uncommon. Adenoid cystic carcinoma (ACC), a well-defined entity, occurs most of the times in the parotid, submandibular glands and palate, as far as the intraoral site is concerned. Adenoid cystic carcinoma tends to have an indolent, extended clinical course with wide local infiltration and late distant metastases. We are presenting a case of an adenoid cystic carcinoma of the buccal mucosa in a 65-year-old male patient.
A simple diarrhea can ruin someone else’s day, but how worse can it be when an individual suffers from stomach cancer? This type of cancer develops once the cancer cells take over the lining of the stomach. It then spreads on to the other locations inside your body. It is also considered as the top 5 leading cancer types throughout the world. To know more about stomach cancer, read the article below: Stomach Cancer Gastric cancer, also known as stomach cancer, is the growth of abnormal cells in
