Screening report on either Seven summurai, Wooden Camera or Totsi - Essay Example ny films from the analyst’s perspective, we can, without prompting from film critics or historians, begin to understand Kurosawa’s own sense of Japanese nationalism. Perhaps in even more depth, we might gain a sense of what can be described as traditional nationalism. In other words, in his films Kurosawa forefronts the Japanese pre World War II traditions arising out of patriarchal family, honor, humility, and loyalty to Japan’s imperial emperor. There is, too, a great expression of Kurosawa’s sentiment towards the Japanese role in World War II, and the Japanese nuclear holocaust, which brought about an end to the war in the Pacific. His expressions comes through in the director’s choices and use of symbolism, and in contrasting tradition with the move away from tradition, especially the move away from loyalty to the emperor, and towards World War II militaristic governance. This brief analysis, to focus on these elements, we’ll limit that range of focus to just one film, The Samurai Seven. This film embodies Kurosawa’s own sense of traditional nationalism, his sense of his pre and post war culture, and even comments on the Japanese nuclear holocaust. It is important to keep in mind that The Seven Samurai is a post war film. Kurosawa was well received in Japan, even before his great post World War II film career commenced, which was the period for which he is most well known. Sanshiro Sugata was financed in part by the pre World War II Japanese Film Council because, historian David Cook writes, government officials misinterpreted Kurosawa’s metaphoric message, and perceived the film to be useful as propaganda (Cook, 1996, 833). Most of the Japanese filmmaking in the pre World War II era was focused on works that would help move Japan away from imperialism, and toward a military control over the government that was eager to expand Japanese authority and control in East Asia. For the most part, Japanese cinema was very nationalistic, and,

Descriptive Ethnography - Essay Example The Hispanics as demonstrated by the young Hispanic female emphasize on respect on all their forms of communication and rarely initiate conversations since they prefer to be approached. Mostly, the Hispanics interpret eye contact as a more confrontational body language and further considers that being ignored is as a sign of disrespect and offensive. The Hispanics do avoid too much gesturing and insist on maintaining an accepting attitude. The Hispanics are never contented with some questions such as questions concerning immigration status and religion and are seen to be very expressive in communication. Majority of Hispanics are Roman Catholic which acts as the main source for both information and are also known to be people who are very proud of their heritage hence do not forget their origin (Roll & Irwin, 2008). A young Hispanic female around 19-20 talks on her cell phone while walking towards the cafeteria and is wearing a red jacket with SF 49’ers logo in the back. She m ust be a 49’ers fan or maybe because of the hotness of the 49’ers hence suggesting her love for hot things. The Hispanic girl wears big round gold earrings and has her nails painted red and well kept. She loves herself so much and adores elegance and fashion as the Hispanic culture explains. She looks fashionable and elegance as she puts her black backpack on her left shoulder. The backpack looks empty hence suggesting her love for stylishness. She wears blue jeans that look like the fancy type due to its washed out color and a logo. that is not recognizable. Her full tan purse on her right shoulder looks fuller than her backpack may be to show her adoption to the current trends and fashion of carrying purse. The purse may be carrying her make ups that ensure she looks beautiful all the time and anywhere. She walks so fast but she is not in a hurry maybe because of her fear for eyes and the fact that Hispanic culture does not recognize much the female gender. She must be hurrying to get away from the possible onlookers or admirers who may get a glimpse of her. She wears a smile on her face with her head rocking front and back perhaps to gain confidence. She does not seem to be having enough confidence especially when she is amidst many people. She does not seem to care about what happens around her as she hurriedly disappears into the cafeteria without looking sideways (Roll & Irwin, 2008). The patterns of communication amongst the African Americans are mostly familiar with Anglo American patterns. The African Americans are largely affected by the past incidents of racism and sense of subjection in their interactions thus making them show respect at all times while communicating. This group of people believe in a prolonged eye contact which is always seen as confrontational or aggressive and would mostly seek assistance from the religious leaders if need arose (Pinn, Finley & Alexander, 2009). The African Americans do not address people by their first names which are construed as lack of respect but may use the first names if they are urged to do so. This group of pe

Nonsurgical Endodontic Management Case Study

Nonsurgical Endodontic Management Case Study Introduction The main aim of any endodontic treatment is to thoroughly debride and disinfect the root canal system followed by the contouring of root canal walls and apical tip, for the purpose of sealing the root canal completely with a condensed, inert filling material. Failure to acknowledge the presence of an additional root canal during an endodontic treatment is amongst the major causes of an endodontic treatment failure. Other causes include inappropriate canal instrumentation, incomplete obturation and untreated major canals. An important key to success of any root canal treatment is proper understanding of the anatomy of root canal system this can be achieved by knowledge of the morphology of the root and root canal systems of teeth and diagnostic imaging techniques are required for successful root canal treatment, especially in mandibular premolar teeth (England et al. 1991). In-depth knowledge about the occurrence of atypical external and internal root canal morphologies contributes to the success of root canal treatment. It has been indicated by slowey that due to the variations in the root canal anatomy of mandibular premolars, they have a high flare up and failure rate and are hence the most difficult teeth to treat. Both the mandibular first and second premolars most often have a single root and a single canal, however, anomalies of the root and root canal systems as well as multiple canals have been reported in the literature (Baisden et al. 1992, Robinson et al. 2002).4 Zillich and Dowson have, in a definitive anatomical study, unveiled the occurrence of three canals in mandibular second premolars to be 0.4%.5 The mandibular first premolars show a large variation in the occurrence of number of root canals and apical foramina. Data from anatomical studies report that three rooted mandibular first premolars are rare, about 0.2%.6 This case report presents a case of a successful nonsurgical endodontic management of a mandibular first premolar with three separate roots using Cone Beam Computed Tomography (CBCT). Case Report A twenty four year old female patient of Indian origin, with the chief complaint of intermittent pain along with food lodgement in the lower left back region of jaw since 3 months, was referred to the Post Graduate Department of Conservative Dentistry and Endodontics. Patient also complained of bleeding from gums while brushing since eight months. Medical and dental history was non-contributory. On clinical examination, patients oral hygiene was found to be moderate. Deep occlusal carious lesion was seen with respect to tooth # 34 and 35 and both the teeth were found to be tender on percussion, with no associated periodontal pockets. Neither the affected nor the contralateral side of the crown of the mandibular first premolar showed any unusual anatomy in terms of number of cusps and dimensions. A lingering response was seen on heat testing and electric pulp testing. No evidence of swelling or sinus tract was seen. Intra oral periapical radiographic evaluation of the involved tooth revealed normal mandibular first premolar root anatomy. There was widening of the periodontal ligament space with periapical radiolucency around the root of tooth #34. A diagnosis of irreversible pulpitis was made based on clinical and radiographic evidences. After the administration of local anesthesia (2% Lidocaine with1:80,000 adrenaline), access was gained to the pulp chamber under isolation and conventional access opening was done to locate the canal. Tactile examination of the walls of the major canals was done with a small precurved pathfinder file, while locating the canal, which was proceeded slowly down each wall of the major canal, probing for a catch. A slight catch may indicate the orifice of an additional canal, especially in case of the buccal and lingual walls, because these are not generally visible on the radiograph. . On thorough inspection of the pulp chamber floor, three separate root canal orifices were detected (one mesiobuccal, one mesiolingual, and one distal). With the help of a pathfinder file, access cavity was temporarily sealed with Cavit, and to confirm the root morphology, the patient was referred to an oral and maxillofacial radiologist for a cone-beam computed tomography. CBCT of the mandible was performe d using the CS 3D imaging, after obtaining an informed consent of the patient. A three-dimensional image of the mandible was obtained. The involved tooth was focused, and the morphology was obtained in transverse, axial, and sagittal sections with a thickness of 0.48 mm, along with three-dimensional reconstructed images. The axial image obtained from CBCT confirmed the presence of three roots in mandibular first pre molar # 34. The roots were found to be mesiobuccal, mesiolingual and distal . After re-isolating the tooth, coronal flaring of all the three canals was carried out using Gates Glidden drills and working length was determined using an apex locator, which was later confirmed by a radiograph. The canals were cleaned and shaped up to ISO #35 masterapical file under copious irrigation with 2.5% sodium hypochlorite and 17% EDTA. The root canals were dried with sterile paper points, followed by temporary sealing of the access cavity with Cavit (3M ESPE AG, Seefeld, Germany). The patient was re-scheduled a week after for follow up. The tooth was found to be completely asymptomatic after a week, and the roots canals were obturated by cold lateral compaction of gutta-percha using AH26 sealer (Kemdent; Associated Dental Products Ltd, Wiltshire, UK). A postoperative radiograph was taken (Figure 3B), and the access cavity was permanently restored using universal amalgam restorative material. Discussion Diagnosis and management of extra roots and root canals in mandibular premolars is one of the major challenges in endodontics. 8-18 Therefore, the clinician must have an appropriate knowledge about the normal root canal anatomy and the most common variations associated. Inability to find, debride and obturate a root canal has been reported to be a major reason for failures in endodontic treatment. 19Based on race, only one study by Trope et al. has showed an increased prevalence of two or more canals in mandibular first premolar in African American patients as compared to Caucasian American patients .20 The failure rate in mandibular first premolar was shown to be 11.45% according to the Washington study. 21This might be due to the extreme variations in the root canal morphology of the mandibular premolar teeth and therefore poses an endodontic challenge to the clinician. Considering the high prevalence of aberrations in these teeth, an endodontist must suspect the presence of one or more missed canals, when a patient returns with persistent post-operative pain or sensitivity to hot and cold. Judicious use of high-end diagnostic aids should also be considered in such cases. Radiographs obtain two-dimensional images of three dimensional objects, resulting in superimposition of the images. Therefore, they are of limited use in complex root canal anatomy cases. Interpretation based on a two-dimensional radiograph may circumspect the clinician of the presence of aberrant root canal anatomy but cannot completely show the morphological structure of the root canals and their interrelations .22 Based on the results of previous studies carried out by Kottoor et al., and La et al. wherein spiral CT was used for the confirmatory diagnosis of morphological aberrations in the root canal anatomy, CBCT of the involved tooth was planned in the present case .23-25 The 3D CBCT images in this study revealed three roots (mesiobuccal, mesiolingual and distal ), with three distinct canals, each canal having a separate apical orifice as compared to the two dimensional radiograph which showed only one root, just like the anatomy of a typical single-rooted mandibular first premolar, that led to a false diagnosis and treatment plan. This is probably why the mandibular first premolar is known as an enigma to the endodontist. However, the high cost and inaccessibility to the patient as well as the extra radiations as compared to the standard radiographic methods makes its routine use limited.We can therefore conclude that a thorough knowledge of the root canal anatomy and its variations, careful interpretation of the radiographs, close clinical examination of the floor of the chamber and proper techniques of access opening along with adequate magnification are essential for successful treatment outcome. Conclusion The mandibular premolar teeth can present with extremely complex root and root canal system morphology, and if not considered during treatment can lead to difficulties when performing root canal treatment. The use of 3D CBCT is a valuable tool in studying the variations that may occur in root canal anatomy.

Deadbeat Parents :: essays research papers

Parents who do not pay their child support are deadbeat parents. This creates a hardship for the case managers in the child support office, the legal staff in preparing documents and court appearances, but most importantly, the children who are the recipients of the child support. Child support enforcement exists to help ensure that every child receives the support that is required by law. This process begins through court ordered divorce, paternity genetic testing, or application made directly to the child support office. Through a court ordered divorce proceeding, the absent parent (the individual who is not awarded custody) is required to pay child support. Guidelines are established for determining the amount to be paid and an order is established. If an individual is in disagreement with an order a paternity genetic test can be given. A custodial parent can complete an application to submit to the local child support enforcement office. Once this is received, the application goe s through several processes. First, an establishment case manager reviews the paperwork and has appointments with both parties involved. Once the order is established, through the case manager or child support court, the case goes to an enforcement case manager. This person is responsible for enforcing the child support order by maintaining contact with the absent parent, securing employment information, address, etc. If an individual fails to comply with the order, another process begins. The case is referred to the legal department for enforcement. Paperwork issued from the court is mailed to the individual requiring them to appear in court on a specific date and time. If they do appear, they are given an opportunity to explain why they are not meeting their order. If this is acceptable by the judge, they are given another opportunity to comply. In most cases, the absent parents do not show up for court and a contempt warrant is issued. These deadbeats are not easily found. The ch ild support enforcement office has to depend on information received from concerned citizens.

Ways to make learning a fun experience in school

East is east and west is west. Never the twain shall meet' said Rudyard Kipling. ‘Learning is learning and fun is fun. Never the twain shall meet' said a student. It is time to make that possible now. It is time to end the era in which children hated school. It is time to get rid of the old teaching techniques and keep in pace with modern day technology. It is time to stop using the chalk on the board and make a change in the lives of the generations to come. We are making progress. India in the 1 lth century had schooling in gurukuls.Young boys were taught archery and sword fighting skills. Children used to sit under trees with their slates and chalks and practice sums. Today, we belong to a digital generation that demands innovative methods of absorbing information. Scope in this field is tremendous. Over the years, schools have moved from black boards to smart boards, from typewriters to computers and from a rigid education system to a spontaneous fun experience of school. T he oxford dictionary defines fun as ‘light amusement' but every individual has his own definition of fun.We always find it funny when a child remembers the xact dialogues of the latest film but finds it difficult to answer the questions from their history text book. So to create and exciting atmosphere, the interest of a child is crucial. Audio-video and movies with children's favorite stars help in absorbing the required knowledge. Recorded food preparation television shows and scenes from famous plays can be shown. Colorful pictorials and animations speak louder than a thousand words. Learning in groups with friends also reinforces many facts. Occasional challenges like quizzes and spelling bees help in building an attitude f or many students.Practicals are very beneficial. It would be great to have a multi touch technology where a science student could perform a surgery or an electronics student could assemble and disassemble a computer or a car on the I-pad. User friendly applications would help art students practice their paintings on the smart board before actually starting on a canvas. Online interaction is fun where social studies are concerned. E-program software can be used to exchange knowledge of cultures over the globe. Software should be made in the form of stories with songs as it reinforces important points in the minds of children.Students spend countless hours on social networking sites. These sites can be used for group discussions if the students are too shy to open up in class. Teachers should be provided suitable platforms to host classroom online communities. Project ideas can be shared and there is a teacher and student collaboration. The classroom should be extended beyond the four walls. Projects give need for individual research which pushes students and gives them reason to learn more about their subject. A lot of new ideas and creative inventions are needed for transforming the traditional classroom with ophisticated teaching tools.Visiting destinations of projects is very realistic and enriching. Project tours can be conducted if required, thus increasing the examples and applications of these technologies are growing exponentially. These are the solutions to meet the needs of the 21st century learning environment. Such an exciting environment is a must for an enhanced schooling experience. We do not know for sure where these technologies are taking us but indeed students are finding good strong results. Through everyday explorations like these in the classroom, we are building steps towards the future..

Newspapers’ role in society Essay

Mass media is a distinctive element of today’s society. Together, the different elements are a product of societal change, forced regulations, rising living standards, and technological modernization. Mass media includes mediums such as magazines, television, internet, radio, cinema, video games, and cellular telephones. The ability to mass communicate with these devices has had such a massive impact that Denis McQuail describes that â€Å"the mass media has primary and crucial importance for the integration of the diverse secular worlds of modern men into coherence and unity† (32). There is no doubt among theorists that media is influencing society, but there are different theories that suggest that it may be society influencing media, not media influencing society. This essay shall look at newspapers’ past and present, and how they will continue to affect the world we live in. In the early 1950s after WWII, American communication made deep inroads into Europe, and words like â€Å"mass†, â€Å"effects†, and â€Å"functions† organized research on both sides of the Atlantic (Curran 407). Almost a decade later, some of the biggest research took place in 1959, when Elihu Katz argued that people need to concentrate less on what the media do to people and more on what people do with media (McQuail 71). Dennis McQuail sides with Katz, in believing that peoples contact with media is of utmost importance, stating, â€Å"media is helping in enabling people to bring about a more satisfying relationship between themselves and the people around them† (71). The views are across the board, pointing in both directions, but research continues even today as to what extent life is changing because of emerging technologies. Not only the substance of what is being communicated is important, but just as vital is the process. Technological innovations have assisted in supplying content for our media forms, and also the circuits and motherboards of how they are made are affecting the ways which society operates. Both aspects have a hand in the creation of the world we live in today, and should be realized when reading this essay. Mass media first appeared on the scene as newspapers. The newspaper was the first medium of communication with a genuinely mass character. U.S newspaper firms had slow growth until the 1800s. It was in the 1830s that the population concentration in cities and the spread of mass literacy provided  a market for mass press (Wells 7). The news could finally be spread on paper, rather than word of mouth. The entire world was suddenly in-the-know about what was happening around them. Newspapers made the transition from the realm of the educated, to serving a wide range of people from this time thought the Civil War (Grant, Meadows 8). The development of advertising, telegraph, and improved production methods have assisted newspapers in reaching a worldwide audience, and eventually being the main source of news for years to come. To this day 97% of towns have only one newspaper to choose from for local news (Wells 7). This idea of newspaper monopolies is discouraging to the market, because only one view is being seen on the issue. No single company is at fault though, because starting a newspaper or radio station these days requires far more investment and risk then in previous years. Despite other forms of news, the newspapers industry is still growing today. In 2002, there were over 10,000 newspaper firms in the United States, and over half the country reading a newspaper daily (Grant, Meadows 9). The future of newspapers looks to be heading toward the digital world, against many wishes of traditional newspaper readers. Flexibility from digital methods has increased newspapers’ ability to deliver zoned editions that reduce unprofitable readership in areas far away from print facilities (Grant, Meadows 10). By the end of the 20th century, over two-thirds of U.S. newspapers maintained websites that offered classified advertising (Grant, Meadows 10). According to the U.S. Department of Commerce, the majority of the population prefers to purchase the printed edition rather than viewing the electronic edition (Grant, Meadows 11). This may change though, because digital news is rather new, and websites such as cnn.com can be updated on the hour informing viewers of up-to-the minute news, instead of waiting for the next days edition to receive that same news.

Phases of Preclinical Trials in Drug Development

Phases of Preclinical Trials in Drug Development Introduction The developments of drugs often undergo various processes before being introduced into the market. One of the processes is the preclinical trials. Preclinical trials are conducted to ascertain the effectiveness of the drug on the treatment of the targeted disease (Mulay, 2001). According to the procedures and regulations governing drug development, preclinical trials are conducted in various stages ranging from the first stage to the third stage of phase.Advertising We will write a custom research paper sample on Phases of Preclinical Trials in Drug Development specifically for you for only $16.05 $11/page Learn More Each phase has distinct characteristics, activities and requirements as defined by the regulatory bodies. Apart from determining the effectiveness of the drug, pre-clinical trials are conducted to establish any side effects of the new drugs that may cause harm to individuals (Mulay, 2001). In other words, pre-clinical trials are con ducted to ascertain the effectiveness, mode of application as well as other clinical aspects of the drug before its administration. Preclinical trial phases in drug development In most countries, pre-clinical trials are conducted in three stages or phases. In the first phase, clinical trials are conducted in order to observe the behavior of the new drug in a small sample. In essence, the experiments are conducted using a small population to prove various assertions as well as to establish some aspects of clinical practices during the administration of the drug (Hackshaw, 2011). In addition, the findings in the first phase inform the procedures as well as activities in the subsequent phases. In other words, some aspects in phase two and three are based on the findings of the first phase. In the second phase, further trials are conducted to provide more data particularly on the safety of the new drug and the way it work to treat the target disease (Mulay, 2001). The second phase estab lishes the pharmacological processes as well as the side effects of the drug. In the final phase, the pre-clinical trials are conducted in a larger sample and compare the effects of the drug on the experiment and the standard effect or treatment. The procedure and activities in the third phase is almost a repetition of the first phase. However, the population used for the trials in the third phase is large. In fact, the researchers and medical practitioners conduct the pre-clinical trials through elaborate experimental processes designed to examine the effect of the drug on the subjects as well as the changes in the behavior due to the effects of the new drug (Hackshaw, 2011). Every phase in the preclinical trials is intended to give diverse data concerning the treatment process of the new drug. The information required includes, safety, working processes as well as the doses (Spilker, 2000). In essence, preclinical trials are intended to provide more information on the laboratory p roof of the underlying hypothesis concerning the application of new drug and treatment processes.Advertising Looking for research paper on health medicine? Let's see if we can help you! Get your first paper with 15% OFF Learn More However, before the preclinical trials, the new drug is subjected to the laboratory tests to prove the underlying hypothesis. The laboratory experiments involve testing of theoretical hypothesis on the drug formulation (Mulay, 2001). The laboratory process is always an elaborate process and takes several years to turn theoretical concept into practical treatment. The laboratory experimentations confirm the effectiveness of the new drug. The pre-clinical trials are based on the results from the laboratory experimentations. Similarities and differences in the first and the third phases in the preclinical trials As indicated, the first and the third phase are similar in many cases. However, the differences also exist in many fronts. T he main aim in the first phase of preclinical trial involves establishing the safety of consumption of new drug (Spilker, 2000). The first phase follows the laboratory experimentation process. Therefore, the first phase in the preclinical trials is conducted on individuals. The procedures in establishing the effectiveness of the drug in the first phase are similar to the procedures in the third phase. In proving such drugs or treatment, the doctors carry out activities ranging from amassing statistics on the dose, timing as well as the wellbeing of the treatment. The involvements of people in the first phase of preclinical trials enable first-hand treatment or the amalgamation of various therapies (Spilker, 2000). The activities involved in the first phase of preclinical trials involve the steady amplification of the prescribed amount of drug under study. The gradual increase in the dosage known as dose escalation enables the dosage that produces optimal results without causing hars h side effects. In the process, the patients are initially administered with smaller amounts of the drug dosage (Hackshaw, 2011). In most cases, side effects are not observed in the first administration of the drug to a patient. The drug has to be applied to several patients in order to establish the side effects. Also included in the first phase of preclinical trials is the method of administering the drug. Investigators establish if the drug is administered orally or injected into the bloodstream. In addition, the fisrt phase establishes the reactions of the drug in the body including the way the drug spread into the body. The prescribed procedures are similar to the third phase and the only difference is the population of the patients being used. The performances of the first phase of preclinical trials are estimated to last for about a year. In addition, the first phase of preclinical trials often encompasses a minimal number of participants ranging from ten to twenty a distinct ive difference with other phases. Further, the first phase offer treatment to individuals’ diseases working against the preceding therapies (Mulay, 2001). In contrast, the third phase of preclinical trials aims are to undertake comparison measures between the latest therapies portraying potential outcomes when administered to a small number of patients exhibiting a particular ailment and the contemporary care standards of the explicit malady (Hackshaw, 2011).Advertising We will write a custom research paper sample on Phases of Preclinical Trials in Drug Development specifically for you for only $16.05 $11/page Learn More In addition, the third phase involves gathering of data from a large figure of patients. As a result, the doctors are capable of establishing the effectiveness of the new drug as well as the extent of its side effects on the patients compared to the current standards. Another important aspect of the third phase of preclinical trials is that the experiments are often carried out as random trials. In essence, investigations on the standard application of the drug are conducted unevenly. Further, the third phase of clinical trials not only focus on the patients with a specific malady, but also encompass patients of diverse ages, ethnicities and both sexes thereby producing results applicable for a large population sample (Hackshaw, 2011). Given the long timeline in the third phase of clinical trials, large sample or population is required to complete the investigation. In most cases, the sample range between seven hundred to two thousand participants. Moreover, the success of the drug in the third phase preclinical trial leads to the application to the approval of the drug by the authorized bodies such as Food and Drug Administration (FDA). The approval of the drug due the successes in the preclinical trials shows that the drug can be administered for a precise use. Investigator brochure The IB (Investigatorâ€⠄¢s Brochure) is an all-inclusive document in drug development. Actually, during the drug preclinical trials, the manuscript sums up the body of info acquired in the study. Once the IB is obtained, it is modernized with fresh information. Throughout the entire procedure of drug development, the document (IB) is critically significant (Hackshaw, 2011). The human areas under discussion gathered in preclinical and clinical trials in study of drugs gets Investigator’s Brochure relevant when compiling data. All through the clinical trials, the investigators obtain essential insights from the IB for the administration of study subjects and study conducts (Hackshaw, 2011). The clinical trial protocol with protection measures and key aspects are set up by the investigator’s brochure. The key aspects may encompass, safety-monitoring procedures, techniques of administration, frequency and dosing intervals, as well as study of drugs. On the other hand, an IB helps the investigato r to clearly comprehend the safety measures, observations, specified examination, adverse reactions, and any possible risks accruing during the clinical trials (Mulay, 2001). In brief, the brochure is a guide and an abstract for the segment of the investigator.Advertising Looking for research paper on health medicine? Let's see if we can help you! Get your first paper with 15% OFF Learn More The background knowledge in pharmaceuticals is critical in the investigation process during the third phase of preclinical trials. Moreover, based on the pharmacology and previous human experience of the investigational products, a clinical investigator should be in custody of the guidance (Mulay, 2001). The guide should consider treatment and identification of undesirable drug reaction and probable overdose. The information on the IB must be kept updated through a responsible sponsor. Contents of the investigator brochure in stage one of the product developments The investigator brochure explains all the activities taking place in the first phase of the product development. The brochure explains in details the required insights for the management and conduct of the investigators at the preclinical trials (Spilker, 2000). In addition, the brochure explains the study subjects as well as the effects of the drug throughout the first phase of the preclinical process. The information inc ludes the name of the drug, the development process, the way it works as well as the formula (Spilker, 2000). The specified data regarding the drug are obtained from the results of the laboratory tests. In essence, the investigator brochure in phase one will contain more information about the product. Further, the investigator brochure provides the investigator a summary of the information that guides the trials as well as possible risks and uncertainties that may be encountered during the study (Mulay, 2001). In fact, the brochure will provide the dose development procedure and the characteristics of the subjects that were used in the first phase of preclinical trial. In addition, the brochure will have detailed information regarding the potential risks or the adverse effects of the drug (Spilker, 2000). Moreover, the information concerning the use of the drug, whether in combination or applied singly will also be contained in the first phase investigator brochure. In the dose data , the brochure will provide more information on dose escalations and the observed side effects. Since the first phase is critical in the product development, the investigator brochure will contain more information that provides insights in the application of the drug (Hackshaw, 2011). Moreover, information concerning the drug administration will also be contained on the brochure. In addition, the investigator brochure also indicates how the side effects should be treated. In other words, the investigator brochure contains details on the possible side effects and the manner in which such adverse effects should be countered (Hackshaw, 2011). All the information in the brochure is based on the procedure provided and the results obtained from the trials. In the first phase of the product development, the investigator brochure provides direction on the identification and management on the negative effects of the drug. Conclusion The development of new drug undergoes various stages before being authorized to be used. The phase includes preclinical trials, which are conducted to ascertain the effectiveness of the drug. The preclinical trials are in phases. The first phase of preclinical trials tests the effectiveness and behavior differences of the subjects due to the administration of the new drug in a small sample. Similar aims and procedures are conducted in phase three. However, the third phase requires a large population. The major difference between phase one and phase three is the sample population where the third phase applies the larger sample population. The investigator brochure is critical in the provision of information during the preclinical trials. Specific to first phase of the preclinical trial, the investigator brochure provide the information concerning the new drug. Besides the product information and the investigation procedures, the first phase investigator brochure contains the information concerning the doses, timings as well as the safety of the product.
