A Brief Note On Helicobacter Pylori - 1355 Words

HELICOBACTER PYLORI Helicobacter pylori have been implicated in cases of chronic gastritis, peptic ulcer diseases( includes duodenal and gastric ulcers). Even though these diseases were linked to stress factors, in 1983, Australian microbiologists Warren and Marshall proved that gastritis and peptic ulcer diseases were infectious diseases caused by a bacterium (1). This bacterium has also been linked to gastric carcinoma and Mucosa associated lymphocyte (MALT) lymphoma (2) This organism was formerly classified under the genus Campylobacter because scientists found a campylobacter-like bacterium in the gastric mucus of patients with chronic gastritis. It was thus formerly called Campylobacter pylori, however, further study of the organism at genetic level by analyzing a sequence of the 16s rRNA gene necessitated the formation of a new genus, hence the name Helicobacter pylori (3). Helicobacter pylori is a Gram negative spiral shaped microaerophilic rod (4). The term microaerophilic means that the organism requires small amounts of oxygen to survive. It is also a rapidly motile organism due to the multiple polar flagella (4). The bacterium is approximately 3Â µm long and 0.5Â µm in diameter. The organism has 4-7 polar sheathed flagella which helps it to move in the gastric mucus in the stomach (3). It is also a fastidious organism. This means that it requires special nutrients to grow. The common media for isolation include Skirrow’s medium with vancomycin, polymixin B,

Gender Discrimination Free Essays

Social stratification is the structured form of social inequality within a ranked group of people that bring about unequal financial rewards, such as a person’s income, and power or property, which is brought upon by wealth in a society. The social stratification systems come in many different ways and forms. For example, slavery, castes, social class, race, and gender are just some of the issues that are affected by stratification. We will write a custom essay sample on Gender Discrimination or any similar topic only for you Order Now This essay will particularly focus on the issue of stratification by gender, or in other words, gender inequality. Gender inequality or also known as gender stratification, is the unequal distribution of a society’s wealth, power, and privilege between females and males. (Scott and Schwartz, 2000). When the issue is approached, it is evident that the majority of the women are the oppressed as in turn the men being the oppressor. This idea of the oppressed vs. the oppressor is evident throughout history; even in religious terms, some can date back to God’s creation. For example, in the Bible, God had caught Adam and Eve eat from the tree of the knowledge of good and evil, which was forbidden. It is written in the Bible, â€Å"To the woman he (God) said, I will greatly increase your pain in childbearing; with pain you will give birth to children. Your desire will be for you husband, and he will rule over you. † (Genesis 3:16). Around the mid-nineteenth century until nowadays, three beliefs about women and men have prevailed as part of biology or evolution. One, men and women have different psychological and sexual natures, two- men are inherently the dominant or superior sex, and three – both male female difference and male dominance are natural. † (Bem, 1993). Considering these three beliefs, women experience gender inequality in different environments, stereotypes, and occupations. For example, women are stereotyped to be only a stay at home wife and to be in an environment where they are responsible for cleaning the house, cooking dinner, and taking care of the children. Nowadays, there are more women known to have jobs and not a stay at home wife, but yet they are still responsible, or show some responsibility for cleaning the house, cooking dinner, and taking care of the children. As for occupations among women, they experience the limitations of the occupations available. Women also experience less pay or earnings, and the devaluation of their work by society. An article, Social Class and Gender, written by Nancy Andes, expresses occupational stratification by gender inequality through the comparison of three theoretical frameworks or perspectives. The first theoretical framework is the sex segregation model, which is where sex is the only characteristic that affects the placement of a worker into a profession or occupation. The second theoretical framework is the pure class model, which is where the workers’ position of determined by their status or position in the society and how much authority and ownership they possess. The third theoretical framework that is used is the integrated gendered social class model, which is where gender and class perform together that affect the positioning of women and or men in the labor force. After Andes introduces the three theoretical frameworks, she explains each frameworks or approaches in depth, in relation to a table that expresses the earnings and occupations of men and women. The source of the table, or known as empirical evidence, is taken from the UC Bureau of the Census in 1989. The table expressed many different types of employment in the labor force. Within that employment of occupation, the table included the percentage of women within that occupation, women’s annual earnings within the occupation, and even the men’s annual earnings in that same occupation.

A Domestic Dilemma by Carson M Essay Example For Students

A Domestic Dilemma by Carson M Essay Carson McCullers story A Domestic Dilemma depicts a family torn by both compassion and suffering. Martin, a loving and understanding husband must deal with his familys problems. Martins wife, Emily, distraught by her new environment, initiates her familys difficulties with her drinking habits. The story examines a familys severe problems, and yet also illustrates the depth of love and loyalty that allows people to survive adversity. McCullers examines within the depth of one family how the full spectrum of love can destroy the romantics of love. The conflicts in the family surround Martin and Emilys relationship. Emilys drinking habits initiate a confrontation with Martin. When Martin inquires about his wifes earlier drinking, she immediately responds because I drink a couple of sherries in the afternoon youre trying to make out a drunkard in a sharp, unforgiving tone(99). According to Roberta Caplan, some people may drink abusively during a personal crisis and then resume normal dri nking (Groiler) which explains Emilys rhythmic sorrow filled with alcohol(102). In addition, fear and worry for his wife an children make Martin feel uneasy. Returning from work a year ago, Martin stumbled upon his children crying and his wife intoxicated after the baby had been dropped on her frail skull(100). Martin then hired a maid in order to watch the children and look after Emily(100). Significantly, the settings effect on the familys relationship demolishes their closeness. Martins surroundings seemed vast and somehow desolate because he is aware of his wifes displeasure living up north (97). Being away from her family and friends in Alabama, Emily takes out her frustration of her new environment on her family(100). Many flaws exist within this family;however, the family still seeks comfort in one another. Although Martins family faces dilemmas, the love in the family remains evident. Initially, the devotion that Martin shows towards his children illustrates his good nature. Martin views his childrens faces as radiant as flower petals, equally loved (103). Moreover illustrating his love for his children, Martin kissed the tiny hand that lay palm-upward (103). Furthermore, Martins hope to hold his family together exhibits his affection for his family. Martin constantly attempts to calm his wife in order to avoid displays of anger(101). Please go upstairs,(101) Martin begs of his wife so the children do not get upset seeing their mother frustrated. Lastly, the physical and emotional desire for Emily that Martin has, further shows how he cares for his family. Comforting his wife, Martin exhibits his love for her(104). Martin watched Emily as she slept and his old anger vanished(104). McCullers fully examines the immense complexities of love(104) in depicting both the conflict an love within one family, and how this can tear a family apart. Problems such as drinking excessively cause relationships to deteriorate. The dependence on each other and love for one another holds a family together. Ultimately, McCullers past encounters with alcohol and family drove her to write this story which shows that the choices people make vary depending on their intentions(Groiler).
