From the Paper
"Buffers and buffer reactions are one of the most important reactions in the human body. The body has a limited tolerance for changes in pH. The ability to maintain proper pH can present as a primary cause of concern, or it can represent a secondary complication. The most common problem associated with pH shifts are heart arrythmias and pulmonary problems. The six chemicals discussed in this research are the most important ones for maintenance of proper pH. However, there are many others that play a minor role. Understanding how the body maintains homeostasis is one of the most important concepts that any medical professional can know."

From the Paper
"This substance was discovered in 1824 by the Swedish chemist Jons Jakob Berzelius. (SILICON or SILICA) It has an atomic number of fourteen and has various metallic characteristics. An important fact is that silica is never found in its natural state but as a silicate ion (SiO4), combined with oxygen. (SILICON or SILICA). It is found in silica-rich rocks such as obsidian, granite, diorite, and sandstone. Feldspar and quartz are the most significant silicate minerals. (SILICON or SILICA). Silica is also be found in "... skeletal parts of various protists and animals, such as certain sarcodines ...diatoms , and sponges , and in the stems and other tissue of higher plants" ( Silica)."

Conclusion
From the Paper
"The shape of a bacterium is used to determine its name. Since Streptococcus mutans is of a spherical shape, the bacteria were named as coccus. The major genera of Streptococci were named as Streptococcus and Staphylococcus. Another name associated with Streptococci is diplococcoi though a change by a gram negative in its feature would put them in a completely different genus like Neisseria or Branhamella. Streptococci are also found in other forms though the major shapes are in the form of a small comma known as Vibrios and a spiral shape known as Treponema."

Summary
From the Paper
"Periodontal disease affects up to 90% of the population and surgery has been the first choice of therapy. Surgery, however, does not restore lost periodontium. Restoration can happen if periodontal ligament cells can colonize root surfaces over gingival epithelial cells, gingival fibroblasts or osteoblasts. The application of microporous membranes under periodontal flaps during surgery eventually brought this effect about. A biodegradable membrane would make a follow-up surgery unnecessary and benefit both patient and surgeon from further health condition and cost."

Abstract
This paper explains that antidepressants are a group of psychoactive medications that alleviate the signs and symptoms of mood disorders with a pre-dominantly depressive mood. The paper then explains that an understanding of the major mechanisms of action of these drugs can be best accomplished through understanding the pathogenesis of mood disorders. The paper then relates that, by understanding the mechanism of SSRI (e.g. venflaxine), it is possible theoretically to infer the neurobiological component of the pathogenesis of increased suicidality in depressed adolescents.
From the Paper
"The psychopharmacologic effectiveness of anti-depressants center around one of three mechanisms of action: increasing serotonin and norepinephrine levels through blocking of presynaptic 5-HT and norepinephrine receptors (i.e. interruption of negative feedback for neurotransmitter regulation), blocking of serotonin or norepinephrine reuptake by the presynaptic neuron or inhibition of MAO to interrupt deactivation of these neurotransmitters (Bhalla & Aronson). Selective serotonin reuptake inhibitors (SSRIs) will be discussed in further detail."

Abstract
This paper explains that the search for life beyond this planet must be built on a solid understanding of how life managed to emerge on Earth. The author examines the development of extraterrestrial theories about the origins of life by beginning with an examination of previous theories of origin. The paper then presents current research and the empirical basis for current theories with implications for the search for extraterrestrial life. The author also offers some possible avenues of future research and examination, which could help refine the understanding of the origins of life in the universe.
From the Paper
"In fact, the presence of a liquid like water seems to be the only major prerequisite for the development of life. Without a liquid, the complex chemical reactions required for the emergence of life are presumed impossible. But, that's not to say that the liquid in question must be water. Many researchers are exploring the possibility of life developing in more unorthodox liquids, such as methane, ammonia, or even sulfuric acid. Life on earth may have simply developed to take advantage of the very abundant liquid water; water's presence may have only been happenstance."

Abstract
This paper examines why organic chemistry is important in the writer's life. Specifically, the paper looks at how organic chemistry can offer tips on how to better treat oneself. Further the paper also offers insight into why human beings act as they do and why the human brain occasionally malfunctions - sometimes with tragic consequences. More than that, the writer looks at what organic chemistry can teach us about the surrounding world - and what it can teach human beings about the past and future.
From the Paper
"Organic Chemistry is important to each and every one of us in the sense that it reveals to students the myriad ways in which chemicals reacting and interacting within the body allow us to perform our daily activities - and shape the kinds of human beings we become. For instance, students need to know all about vitamins C and E and what these elements do within their bodies so that they can know all about why it is vital that certain fruits and vegetables be ingested by them on a daily basis. In my own case, it was not until I came to understand what I was doing to myself on an organic, physiological and biological level when I neglected certain foods that I began to see an improvement in my own health and in my vitality over the course of a long day."

Abstract
The paper examines the effects of lysergic acid diethylamide (LSD) on the central nervous system and focuses on the body of research about the link between its interaction with serotonin receptors and the onset of hallucinations. The paper discusses how although one receptor in particular is believed to be the key, the lack of research on the subject in general precludes a definitive determination at this time.
From the Paper
"Lysergic acid diethylamide (LSD) causes hallucinations and detachment from reality. Since neuro psychiatric disorders such as schizophrenia present very similar symptoms, these profound if episodic perceptual distortions can be viewed as symptoms of temporary damage to the Central Nervous System. Serotonin receptor activation has long been thought be directly affected by LSD, yet after 30 plus years of research, the precise mechanism by which LSD bonds with which of several serotonin receptors, remains a matter of conjecture."

Abstract
In this progress report, a student addresses the importance of learning to have patience with the difficult and time-consuming procedures of an advanced chemistry course. The paper points out that, in chemistry experiments and operations, it takes great lengths of time to separate various chemicals, such as acids and other various bonding agents and solvents. The paper recounts the student's attempt to speed up one such process, only to realize he had ruined it. Through this error, he realized that he had not been patient enough to effectively see the bonding procedure to its conclusion. The paper concludes with a list of helpful future strategies for dealing with impatience.
From the Paper
"After the class, my professor asked me to have a meeting about the project. Although she was annoyed at the failure of my actions, she was extremely open to solutions to the problem. I had not even realized that I had rushed the project at first, but she had quickly understood what had gone wrong. Our discussion lasted for nearly an hour, and we both came to the conclusion that there needed to be exercises for me to solve my problem with patience. Although I had clearly understood how to accomplish the projects in class, there was another dimension of chemistry, which I needed to learn. The professor was telling me that chemistry was more than just tables, procedures and memorization, but had more to do with learning to manage one's time in an efficient manner. This discussion awakened me to the realization that I had to learn to properly evaluate my time, especially at this advanced stage of chemical studies."
