Synthesis of 7.7-Dichlorobicyclo [4.1.0]Heptane †Phase...

Abstract The preparation of 7.7-dichlorobicyclo [4.1.0]heptane which is also known as 7,7-dichloronorcarane was done by reacting cyclohexene , chloroform and a base( 50% aqueous sodium hydroxide) with benzyl triethylammonium chloride. The latter being a water soluble phase transfer catalyst (PTC).reaction was performed at room temperature and was distilled at atmospheric pressure. The mechanism of action of the above mentioned PTC is described in the text along with the mechanism for the addition of a dichlorocarbene. The percentage yield obtained was 38.80%. This is considerably low due to an unfortunate spillage of the product at the stage of semi- micro distillation. Introduction Phase transfer catalysts (PCT) are used to†¦show more content†¦The vigorous stirring also increases the turbulence in the reaction flask which facilitates collisions between the primary reactants. This is needed for the reaction to occur at an optimum rate. Hence, the rate constants of the reaction increase as stirring speed increases. If the reaction mixture was not stirred at high speeds, the reaction will not proceed to yield maximum product in the given time and will result in low percentage yields. It was during this stirring time that the action of the PTC is significant. The mechanism of action of the PTC is illustrated and explained below. The base used in this reaction is a strong one (NaOH) which dissociated completely in the aqueous phase to give an excess of OH ions which is needed for the generation of the dichlorocarbene in the organic phase. As seen above, benzyl triethylammonium chloride undergoes a nucleophillic substitution with NaOH. The hydroxyl group f rom the base displaces the chloride group on the PTC which results in the formation of a quaternary ammonium hydroxide. The PTC is now able to transport the OH ion to the organic phase where it can react with chloroform. The three step mechanism describing the formation of 7.7-dichlorobicyclo [4.1.0]heptane is illustrated and explained below. In step one, the hydroxyl group

Urban Population Of Ethiopia And Its Socio Economic And...

Today’s world society is rapidly becoming urbanite and such rapid urbanization comes up with its multi variant socio economic and environmental consequences. Among many variables characterizing urbanization in the century, the most prominent one is population growth rate. World urban growth population rate is about 1.8% where as that of Africa and Ethiopia is 4.4% and 5% respectively (UN- Habitat 2004/2005; PASDEP 2006). Though Ethiopia is one of the least urbanized countries where about 83.8% of population lives in the rural areas, it is one of the countries where high urbanization process taking place. Currently, urban population of Ethiopia is about 11.7 million. Studies show that the figure will increase to 17.8 million in 2015 and 22 million by 2020, with annual growth rate of 5% (yewoynishet, 2007; PASDEP, 2006). Over the years, rising population has led to unsustainable exploitation of natural resources for the consumption of environmental good and services. Unplanned economic growth, industrialization and vehicular emission could also affect urban environment. The effect of these problems might include degradation and pollution of environment like ground water, soil, river bank, air and other urban ecosystem (Cobbett, 2006; National Urban Planning Institute of Ethiopia, NUPI, 2003). Regarding to this, the 1960s were the milestone that marked the birth of the environmental movement.

The Manipulation Of Immunoglobulin Architecture Essay Free Essays

Immunoglobulins, produced by B-lymphocytes, are the chief go-betweens of humoral unsusceptibility, and lacks at this degree affect the organic structure ‘s response to infection. The use of Ig position in the intervention of human diseases consists of two chief paths that have the intent to augment the concentration and alter Ig in the affected host. On one manus lies the external disposal of human Ig in patients that are wholly lacking or compromised and are considered to profit widely from an endovenous extract. We will write a custom essay sample on The Manipulation Of Immunoglobulin Architecture Essay or any similar topic only for you Order Now The other is the use of immunoglobulin production via indirect immunisation ( inoculation ) that forces the human organic structure to bring forth a series of Igs that are antigen specific for the peculiar antigen administered via the inoculation path. Immunosupression ( i.e. the lowering of the innate immune response ) has been widely used in malignant neoplastic disease therapeutics and is discussed last. IV ADMINISTRATION OF IMMUNOGLOBULIN ( inactive immunisation ) The U.S. Food and Drug Administration ( FDA ) have approved endovenous auxiliary Ig interventions for a series of chiseled diseases such as: primary immunodeficiency, immune-mediated thrombopenia, Kawasaki disease, hematopoietic root cell organ transplant ( in patients A ; gt ; 20 old ages ) , chronic B-cell lymphocytic leukaemia, and HIV in kids. However, Ig merchandises which are chiefly unfertile, purified Ig G ( IgG ) derived from a pool of givers ( normally 3,000-10,000 ) are besides normally used throughout the universe for the intervention of assorted other diseases such as idiopathic diseases ( unknown cause diseases such as perennial abortions ) and infections. The curative usage of Ig IV interventions consists chiefly of supplying with an increased protection versus infection for immunocompromised patients, may besides assist prevent patients with Kawasaki disease from developing coronary arteria aneurism or increase the figure of thrombocytes in patients who have life endangering idiopathic thrombopenia peliosis ( ITP ) and prolong sustaining of transplants in graft surgery ( Shehata et al, 2010 ) . However, the fact that the Ig is gathered through a pool of givers, poses a important infection menace to the infused persons. Although the hazard for HIV and Hepatitis B transmittal remains low due chiefly to obligatory proving since 1995, the hazard for acquisition of several other viruses and bacteriums, or even smaller life signifiers such as prions and mycoplasma is considered important ( Carbone, 2007 ) . Furthermore, the transfused Ig is non 100 % pure, since it frequently contains little sums of cytokines, CD4 cells, CD8 cells, and human leucocyte antigens ( HLA ) . All the above blood merchandises are known to bring forth and rarefy a important inflammatory reaction to the infused host, and presently the effects caused by these by merchandises of Ig interventions is non sufficiently elucidated. IgG has a half life in the circulation of about 21 yearss, so endovenous extracts of about 600 milligrams of IgG per kilogram organic structure weight given every 3 to 4 hebdomads maintain an IgG degree of about 500 mg/dl ( about 50 % of degrees in healthy grownups ( Quartier,1999 ) . Activation of inflammatory tracts by the extract procedure ( extract related reaction ) or by composites formed by antibody adhering within the receiver host seems a likely mechanism for the inauspicious effects mentioned above. The rate and badness of reactions to endovenous preparations of IgG are greatly reduced by decelerating the rate of extract and by administrating a prophylaxis with paracetamol and an antihistamine. However, its usage is still non accepted in many instances with the illustration of a Cochrane Systematic Review ( Ohlsson, 2010 ) that has late concluded that there is still deficient grounds to back up the everyday disposal of IVIG in babies with suspected or later proved neonatal infection. For instances such as primary lack where immunoglobulins act as replacing therapy and are perfectly indispensable for endurance, new IVIGs have been developed such as the Flebogamma 5 % IVIG intervention ( Ballow, 2009 ) , which is considered to further heighten the pathogen safety border due to pasteurisation and pore microfiltration. Inoculation Recent progresss in inoculation include the betterment of viral-vector vaccinums that nowadays remain the best agencies to bring on cellular unsusceptibility and are demoing promise for the initiation of strong humoral responses. Targets range from certain types of malignant neoplastic disease to a huge array of infective diseases ( Draper and Heeney, 2010 ) . The chief job with this design is that the innate immune system readily recognises the viruses and viral vectors used in the vaccinum readying that renders this means insecure for wider usage, such as cistron therapy ( Huang, 2009 ) . The outgrowth of biological stuffs that can impact the immune system is a underdeveloped field aboard immunology. These stuffs can present antigens through specific intracellular tracts, leting tight control of the manner antigen presentation to T cells. Materials are besides being designed as adjuvants, to mime specific ‘hazardous ‘ signals in order to pull strings the attendant cytokine environment, which influences how antigens are farther interpreted by T cells. The development of contraceptive vaccinums against human papilomavirus has been hailed as one of the most important progresss of recent old ages by most communities and research workers and it is expected to dramatically cut down the mortality in HPV associated cervical and anal malignant neoplastic diseases, but has besides given rise to strict scientific argument ( Hampl, 2009 ) . IDIOTYPE VACCINATION In hematologic malignances, the spread of usage of a different type of inoculation is idiotype B-cell inoculation. Each patient ‘s B-cell malignance is normally derived from a individual expanded B-cell ringer, which expresses an Ig ( Ig ) with a alone idiotype ( Id, variable parts of Ig ) . Therefore, this idiotype can be regarded as possible mark in clinical malignant neoplastic disease inoculation attacks against the clonal B cell line. Currently it is a non-approved, experimental curative option for patients with lymphoma and myeloma. The pertinence of Id vaccinums for B-cell malignances such as chronic lymphocytic leukaemia, mantle cell lymphoma and multiple myeloma demands to be farther tested ( Inoges, 2010 ) . OTHER TYPES OF IMMUNOMODULATION Systemic immunomodulation, besides known as accessory therapy, has been a intervention mode in a assortment of clinical diseases to hike the immune response even though the antigens are non ever known or are sick defined. Systemic immunomodulation often consequences in unwelcome effects, most notably autoimmune disease activation. The therapies include: Interferon In the past several decennaries, IFN has emerged as a major curative mode for several malignant and non-malignant diseases, including hepatitis C, carcinoid tumours, hairy cell leukaemia, and Kaposi ‘s sarcoma. However, apart from the broad side-effect scope profile, IFN is besides found to bring on autoimmune responses with the production of autoantibodies chiefly autoimmune thyroid disease ( ATD ) and thyroiditis ( Kong et al, 2009 ) , ( Tomer, 2007 ) . Interleukin-2 IL-2 is used for the intervention of metastatic melanoma. Similar to IFN, IL-2 has been reported to bring on the development of several autoimmune conditions, most notably ATD. Flt3 ligand To heighten the immune response to a peptide vaccinum derived from a household member of human cuticular growing factor receptor ( Her-2/rat neu ) in prostate malignant neoplastic disease patients, human recombinant flt3 ligand, a growth/differentiation stimulator for dendritic cells, is used as a systemic adjuvant. It is unknown whether the Flt3 ligand can besides bring on autoimmunity. MONOCLONAL ANTIBODIES Monoclonal antibodies ( MoAbs ) have been introduced for the intervention of assorted malignant neoplastic diseases, and their ability to adhere to any specific mark within the organic structure is so used favorably in therapeutics to direct an immune response against the binding tissue site. A recent reappraisal has found little to no infective complications to their usage in assorted types of malignances, although allogeneic in nature ( Rafailidis et al, 2007 ) . Mentions Ballow M.

Quality Improvement in Gastroenterology-Free-Samples for Students

Question: Discuss about the hand hygiene based on PDSA Model Quality Improvement in Gastroenterology Health Care Centre. Answer: Introduction Quality and safety management is crucial in the context of prevention of infections within an acute healthcare setup. The quality management here refers to taking care of the overall aspects of healthcare which are pivotal in maintaining an aseptic condition within the care setting. For the current study we have taken into consideration hand hygiene which helps in reducing the chances of infection within a hospital framework. The focus has been narrowed down to the application of the project initiative within the Gastroenterology Healthcare centre, Toronto upon the Plan DO Study Act (PDSA) model. The paper discusses the issue in more detail focussing upon the importance of hand hygiene and relation of the same in ensuring health improvements within the concerned department. The study further elaborates the role of the nurses in ensuring the efficiency of the aforementioned processes. Description of issue Hand hygiene has been described as the single most effective method of infection prevention (CDC, 2002; World Health Organization [WHO], 2009). The cleaning of hands before, after and during surgical processes is crucial in the prevention of infection through the spread of microorganisms. As commented by Septimus et al. (2014), increased use of hand hygiene equipments have been seen to reduce the incidents of infection spread within healthcare centres. Some of the disinfectants which could be used over here are soap dispensers, alcohol based foam dispensers, paper towel dispensers. The statistical figures showed a 24 % reduction in the healthcare associated infections after the implementation of the disinfection process on a regular basis. This resulted in saving approximately 27 % of the cost of antibiotics (Moraros, Lemstra, Nwankwo, 2016). In the present context, precautionary measures must be taken in dealing with patients suffering from gastrointestinal issues. The staff may encounter exposure to pathogens such as Clostridium difficile, vancomycin resistant enterococci (VRE), carbapenam resistant enterobacteriaceae (CRE). In this respect, rigorous cleaning of the environment with EPA-registered hospital disinfectant has been seen to eliminate some of the microbial agents such as C. difficile which have been known to result in acute gastric infection in individuals (Jones et al., 2016).The aspects of hand hygiene have been further discussed with respect to the PDSA model. The model has four active components such as Plan, Do, Study and Act. The application of the model helps in evaluation of the different steps which could be taken for improvement of quality within the Gastroenterology health care centre. The different steps of the model have been represented with the help of flowchart as follows: What are we trying to accomplish? How will we know that change is an improvement? What changes can we make that will result in improvement? Evaluation of the current scenario through the PDSA model helps in the identification of the problem situation. The goal is to improve quality of services delivered within the Gastroenterology healthcare units through implementation of hand hygiene methods. In this respect, the hand hygiene practices have been promulgated as the cornerstone of preventing infection by IPAC Canada. The improvements brought about by the implementation of such methods can be measured using survey analysis. The reduction in the rate of infection after the application of the cleaning methods could be compared with that of situation before the application of the control methods. The figures so obtained provide an overview about the various loopholes and gaps within the delivery of the care services. The gaps could be further improved with the application of stricter control measures which enhances the quality of the care services. Application of hand hygiene based on PDSA The PDSA model is based upon the objectives of learning through planning, executing the plan, study the gaps in the processes and act accordingly for the mitigation of the gaps. The models have been discussed in more details below: Plan (P): Will implementing sufficient standards of hand hygiene enhance quality care within the gastroenterology wards of the hospital? Will sufficient staff education about the disinfection process help in reducing the rate of infection? What are the necessary standards and guidelines which have to be implemented for achieving success in the above outcome? Do (D): The healthcare team need to do planned activities for bringing about the change Study (S) Did the planning go right? Was optimum education regarding the disinfection process given to the staffs? Were adequate policies and programs followed for the implementation of the objectives within the gastroenterology healthcare centres? Act (A): Based on the results obtained from above interrogation, the gaps or the loopholes are identified which the team could further work upon. Strength of the model There are a number of strengths of the PDSA model such as collective problem and solution ownership. As commented by Smiddy, O'Connell Creedon (2015), the collaborative mode of working helps in building positive relationship between team members. The PDSA model helps in empowerment of team members through common goal synthesis for achieving better clinical outcomes. The PDSA provides a structured environment for the realization of the clinical outcomes (Dai, Milkman, Hofmann Staats, 2015). The PDSA cycles allow the staff to better understand the organizational processes. It promotes a gradual shift in accountability for problems from management to the frontline staff. Limitations of the PDSA model There are a number of limitations of the application of the PDSA model such as loss of momentum due to the removal of a team member. The jumping of the steps of the PDCA cycle may result in adequate learning which fails to address the root cause of the problem (Smiddy et al., 2015). The analysis of the problem situation through PDSA requires unit specific and time sensitive data and is dependent upon human labour for sufficient collection of data. In order to work through individual steps of the PDSA cycle sufficiently longer time is required. Role of the nurse The nurses play a critical role in reducing the rate of infection within a clinical setup by the implementation of sufficient policies and procedures. The influences excised by the nurses within the control of infection can be divided into a number of factors such as intrapersonal, interpersonal and organizational factors. The intrapersonal factors here refer to the level of knowledge, skills along with perceptions or values possessed by the nurses which influence their set of practices. The interpersonal factors refer to the relation of the nurses with their friends, peers and patients which further govern the success of the implementation objectives. The organizational factors refer to the policies norms and culture, which helps in the establishment of the IPAC standards of clinical hygiene and safety. Additionally, inter facility collaboration can promote organizational learning regarding techniques and procedures such as alcohol rub for cleansing hands before, after and during p atient handling, which can prevent spread of infection (Ellingson et al., 2014).The attending nurses need to maintain proper quarantine in dealing with highly infectious cases. They should wash their hands during each step of attending to the patient such as making the bed of the patient along with handing and management of the contaminated soils and articles of the patients. Strength In his respect skill building, peer to peer role modelling have been seen to positively influence the implementation of infection control procedures. As commented by Allegranzi, Sax Pittet (2013), the old and experienced nurses can preceptor the newly enrolled nurses about the disinfection methods and control. The nurses also play a significant role in educating the patients and the respective family members of the patient about the disinfection process. Limitations In a care set up dealing with patients who have been kept in under quarantine, the nurses have to monitor that the family members of the patient are allowed restricted entry. There are similar situations where the nurse has to persuade the family members of the visiting patients to rub their hand with alcohol before they could meet or touch their loved ones (Al-Tawfiq Pittet, 2013). The application of such restrictions often results in heated exchange of words between the nursing professionals and the visitors to the hospitals. Therefore, such ethical barriers limit the potential contributions of the nursing professionals within a care setup. Physicians role In this respect, the physicians attending to the patient can act as a go-to person by the family members of the patient being admitted to the hospital with serious infections. Therefore, they need to practice effective communication skills, where they need to be empathetic in their approach. As commented by Abdella et al. (2014), values and compassion serves as the core factors for ensuring less ethical dilemmas are faced by the practising physicians as per the IPAC hygiene standards. The physicians need to look upon the hygiene standards implied by the nursing professionals and educate the same. They also need to be careful with the equipments for treating patients in the gastroenterological wards. The instruments should be dipped in ethanol after every use. Critical solution by managers In this respect, the managers of the healthcare centres can act as volunteers for the promotion of programs such as antimicrobial stewardship. The antimicrobial stewardship is an excellent tool for improving the clinical outcomes of patients with severe microbial infections by analysing each step from infection contraction to recovery, through constant research into the clinical data and active record keeping (Al-Tawfiq Pittet, 2013). The programs can be also used for educating the staffs for coping with future recurrence of such infections. The implementation of the program can be used for meeting with the loopholes of hand hygiene techniques implemented within the medical wards. The institution wide programs for guideline compliance should be followed by the responsible management for reporting of the cases of infection to the higher authorities, which can help in controlling the rate of infection. Application of PDSA model by managers for controlling the rate of infection in gastroenterology wards Factors Attributes Plan (P) Will implementing antimicrobial stewardship address the loopholes of hand hygiene alone? Will education of the staff in the relevant fields address the issue? What necessary steps need to be taken for the implementation of the program? Do (D) The managers of the institution need to negotiate with the higher authorities for bringing about the change Study (S) Does the clinic possess sufficient infrastructure for supporting the implementation of the program? Did the staff possess sufficient knowledge about the antimicrobial stewardship program? Act(A) The management needs to organise sufficient workshops and training programs for educating the staff in the alternate methods of hygiene implementation Table 1: PDSA model applied by the managers for controlling infection rate in hospitals and clinics (Source: Author) Figure1: Antimicrobial stewardship program (Source: Davey et al., 2015) Strengths and limitations of the managers in healthcare wards The managers can influence positive organizational processes along with guaranteeing swift flow of funds through active engagement with stakeholders, for implementation of the some of the hygiene maintenance protocols and devices. As commented by Smolowitz et al. (2015), the negotiations skills of the mangers are particularly important in generating organizational change by focussing more upon the outcomes. The managers can act as preceptors by training the newly recruited staff about ways to improve organizational performance by employing active engagement policies. However, the lack of trained staff and additional funds often delimit the role of the managers. Additionally, organizational disputes often hinder the application of the said objectives and programs. Effectiveness of Registered nurse in establishment of quality improvement initiative The registered nurse can play an effective role in controlling the spread of infection within a clinical set up. Some of the methods which could be applied by the registered nurse are maintaining active documentation entailing the patient record and history (Unroe et al., 2015). The time of recurrence of chronic infections can be noted down by the nurse. As commented by Grol et al. ( 2013), the relapse of chronic infection can often be related to breach of hygiene practices. The registered nurse can prepare a screening chart detailing the steps that needs to be followed for dealing with a patient suffering from highly contagious infection. The registered nurse can take appropriate action to ensure the protection of the patients. The RN can brief the attending physician regarding the immunization of the patient based upon which referral and isolation strategies could be applied. As asserted by Blot, Vogelaers Blot (2015), advocating an aseptic environment and transmission control processes can prevent the spread of infection. In this respect, some of the recommended nursing standards prescribed by NANB play a crucial role in the prevention of infection through transmission. The NANB standards could be discussed in details for understanding the role played by the registered nurses in infection control. The nursing standards have been four types such as: Standard1: Application of evidence informed measures for control and prevention of infection through microorganisms. The nurse can follow a systematic approach to care by adhering to the guidelines of Public Health Agency Canada. Here, the nurse can track the immunization status of the clients based upon which appropriate quarantine measures could be implemented. This also helps in planning the hygiene standards to be implemented and practised for particular patient population. Standard 2: Application of professional judgement The nursing professional is supposed to take adequate measures for the prevention of chance contamination of the skin and the mucous membranes with microorganisms. Additionally, modification of the practise methods stressing upon the use of personal protective equipments for infection prevention and control can restrict the spread of infection. The use of personal protective equipments such as gloves can reduce the chances of contamination and transmission of contamination (Smolowitz et al., 2015). Standard 3: reduction of risk to self and others through appropriate handling, cleaning, and disposal of materials and equipments. The use of safety devices such as sharp disposal containers, needleless IV systems along with safe disposal can reduce the risk of accidents by checking the spread of microbial agents. In this respect, marking some of the items as single use only can prevent the usage of such articles again. As commented by Murphy (2013), failure in implying with the hygiene standards can be a serious breach of policies and procedures. Standard 4: Use of timely communication strategies with clients and significant others Effective communication of health information to the clients explaining the use of isolation and masks to the patients and the respective family members of the patients can be helpful. As commented by Davey et al. (2015), open communication with the healthcare team can help in the establishment of the safety and hygiene measures. Recommendations for hand hygiene initiative A number of steps could be taken for the implementation of the hand hygiene practices within a care set up. In this response maintaining an aseptic condition is pivotal within the context of an acute health care set up. During the process of handling and management of the patients affected with infectious disease, the nursing professionals need to rub their hands with alcohol everytime after handling such patient population. This helps in the prevention and control of disease through microbial contamination. Additionally, some of the measures which could be implemented over here are provision of sufficient education and training to the health staff regarding the aseptic conditions and methods which could be implemented by them within the care setup. Moreover, evidence based measures along with implementation of the nursing standards (NANB) can reduce the recurrence or breach of protocols of hygiene within an acute hospital and care setup (Melnyk et al., 2014). Conclusion The assignment uses the PDSA model for evaluating the different intervention and approaches implemented within a care set up for establishing sufficient standards of hand hygiene. The application of the model analyses the affectivity of different steps and measures such as team planning of activities along with role-modelling of significant practice methods which prevents future recurrence of such accidents. In this respect, some of the standards of nursing practices can be applied along with promulgation of antimicrobial stewardship can also facilitate in meeting with the demands of health and hygiene standards.
