Clinical Depression - is the most frequently encountered mental illness. Clinical depression is now considered a physical condition in which there is a fault in the brain chemistry. It may afflict up to 5% or more of the population. Symptoms of depression include a distinct change in mood accompanied with an extreme feeling of hopelessness. Other symptoms include: loss of appetite; weight loss; headaches; sleeplessness; loss of energy; and tiredness. Symptoms of anxiety are also quite common. Suicide is common in about 15% of depressed patients. Bipolar Disorder - is also known as manic†¦show more content†¦Rohypnol - is a drug associated with rave parties and comes from the benzodiazepine family. It is considered to be the â€Å"date rape† drug and has become famous for its use in committing sexual assault. It is often given to an unsuspecting victim by dissolving it in beverage while they are unaware. It is similar to Valium TM but has ten times its strength. In combination with alcohol, it can be deadly. Rohypnol is highly addictive and has severe withdrawal symptoms. Its use can cause deep sedation, respiratory distress, blackouts for up 24 hours, and amnesia. Ecstasy - is known as Methylene Dioxy Meth Amphetamine (MDMA) and has street names such as X, Rolls, E, Adam, Beans and Buddies. The initial use of ecstasy results in: increased heart rate; increased blood pressure; dilation of pupils and bronchi; brain stimulation; increased motor activity; tightening of jaw muscles; grinding of jaws; overheating; sweating; heat stroke; and dehydration. The long-term use of ecstasy can result in irreparable brain damage. 3.) Higher doses of designer drugs can result in paranoia, depression and violent irrational behaviour. In general, designer drugs can create a wide range of physical problems such as: hypertension; uncontrolled tremors; total paralysis; seizures; permanent drain damage; and death. 4.) Opioids - are typically used to treat pain. They can produce a feeling of euphoria by affecting regions of the brain that enable us to perceiveShow MoreRelatedRole of Gluthathione Pathway in Discovering Anticancer Compound793 Words   |  3 Pagesanticancer drug, there are several criteria we have to look into. For instance, the role of metabolism, cell environment and also protein homeostasis should be taken into account in discovering anticancer drug. To obtain the pharmacokinetic profile of an anticancer drug during the discovery process, metabolism plays a crucial role where the metabolic liability and the potential drug-drug interactions have to be determined (John Wiley and sons, 2001). Consequently, the metabolic stability of the drug hasRead MoreAspects of Stress Essays550 Words   |  3 PagesResistance Stage: This kicks in when the alarm reaction stage is at a full. The parasympathetic nervous system looks for ways to use resources more cautiously. The body attempts to recharge lost energy and set the body back into a state of homeostasis. Fight or flight is less affective now, so strategies such as denial are used instead. Exhaustion Stage: Eventually the resistances of the last two stages break down and the original states of ANS are regained (sweating, increasedRead MoreIntroduction:. Homeostasis Is The Process Of Maintaining1003 Words   |  5 PagesIntroduction: Homeostasis is the process of maintaining a fairly constant interval environment. Homeostatic mechanisms help us to be independent of our external environment. It helps us regulate our body temperature, pH, concentration of dissolved substance in the body fluids, concentration of glucose in blood, concentration of oxygen and carbon dioxide in the blood and body fluids, blood pressure and concentration of metabolic wastes. Without it, we wouldn’t be able to survive and adapt to our environmentRead MoreThe Effect Of Prostaglandins On The Inflammation Pathway And The Mechanism Of Action Of Nsaids1412 Words   |  6 Pagesstimulus is removed, the reaction will stop and the inflammatory cells will be returned to pre-inflammatory numbers. Prostaglandins play an important role in immune reactions and are therefore often targeted by anti-inflammatory drugs, such as non-steroid anti-inflammatory drugs (NSAIDs). The specific role of prostaglandins and the mechanism of action of NSAIDs will be discussed (Ricciotti; FitzGerald, 2011). Figure 1. Basic diagram of acute inflammation (Reilkoff; Bucala et al., 2011) ProstaglandinsRead MoreCapture Myopathy: Syndrome within Captive Animals Essays645 Words   |  3 Pageswhite muscle disease, the muscle when used causes a change of metabolism from using oxygen to using the stored energy within the muscle. The change up allows for lactic acid to build up and make its way into the bloodstream where it changes the homeostasis of the body: the body pH and the heart output. In essence, if the heart is inefficiently pumping the correct oxygen to the muscle, the muscle will begin to deteriorate and ultimately lead to damages to the kidney and the effector organs.

In times of homeostasis we are comfortable and stable both physically and mentally. Stressors are life events, that may cause physical, mental, emotional, psychological or spiri tual stress and our body and mind â€Å"cope† to attempt to regain that stability of homeostasis Pearson Education, 2015). Both subconscious and conscious responses are used to cope with stressRead MoreThe Scientific Exploration Of Human Motivation997 Words   |  4 Pagessignaling to us we must have because food and water are essential for us to live. When our behavior is directed by means of survival this is something known as homeostasis. â€Å"According to drive theory, the body maintains a condition of homeostasis, in which any particular system is in balance or equilibrium (C.L. Hull, 1951). Any departure from homeostasis, such as depletion of nutrients or a drop in temperature, produces an aroused condition, or drive, which impels the individual to engage in appropriateRead MoreConventional Drug Delivery Systems ( Ddss )1421 Words   |  6 PagesAbstract: With the emergence of more novel and effective drug therapies, increased importance is being placed upon the methods by which these drugs are being delivered to the body. Different methodologies have been heavily investigated as possible solutions , one of these methods are intelligent or ‘Smart polymeric drug-delivery systems’. â€Å"Stimuli responsive† and â€Å"self regulating† drug delivery systems have captured the imagination of researchers, in large part because they suggest a means to mimicRead MoreViruses : The Characteristics Of Life Processes969 Words   |  4 Pagesvirus is constantly changing, it is hard to manufacture drugs and vaccines to combat it. Not all drugs and vaccines will be able to eliminate all of the virions, there will be a few remaining that have resisted the drug/vaccine and will be able to survive and infect more cells, producing more viruses. Those are the two life processes that viruses have. Viruses cannot maintain homeostasis, and this is a very important life process. Homeostasis is being able to control and monitor the internal conditionsRead MoreProteomics Essay754 Words   |  4 Pages4.2 Combination of proteomics and interactomics The study of PPI is fundamental to define the molecular networks that contribute to homeostasis of living organisms. Disruptions in protein interaction networks have been shown to cause diseases in both human and animals. For instance, PPI disturbances have been shown to be involved in cancer caused by p53 mutations [47], neurodegenerative diseases resulting from protein aggregates accumulation [48], and virus-host interactions [49]. Therefore, the
