Political Systems in U.K and U.S Essay Example for Free

Political Systems in U.K and U.S EssayWhat are the similarities and differences between the semipolitical systems in U. K and U. S? When the U. S. Constitution was being drafted, its writers had the British Parliamentary system to base on. The British system was the system they were used to and had learnt since childhood. However, because the monarchy was one of the main things that the fountain colonists had rebelled against, any(prenominal) form of monarchy and most forms of concentrated power were avoided. The most fundamental difference between the political system in the U. K and the U. S is the constitution.The joined pronounces has a written constitution which is very difficult to change. The UK does not have a single document called the constitution but instead its constitutional alimentation are scattered over various Acts of Parliament, any of which can be changed by a simple majority in the Parliament. Similarities Both the U. S. and British political systems hav e a head of state, a court system and an upper and sink house. The U. S political system has a constitution which lays out the rules for political relation and the rights of the people, however, the U.K has documents with constitutional provisions which lay out the same rules. Both systems are democratic in nature, as governments are put in aspire and removed from power by the will of the people and both have systems of checks and balances to limit the power of any one weapon. Head of State In the U. S. political system, the president is the appointed head of state. The president is elected under the electoral college system. In the U. K. , although the prime attend usually has the spotlight on political matters and is the official head of government, the queen or king is the official head of state.The queen officially signs off on acts of parliament and, just as the U. S. president delivers the State of the Union Address every year, the queen reads the Speech from the Throne , which is written by the prime minister. In U. K, the monarch is more of a ceremonial figurehead and it is crotchety for any member of the royal family to directly interfere with the political process. The Upper House The United States has a Senate as the upper house of the legislative branch and the U. K. has the House of Lords. Under the U. S. ystem, each state, regardless of size, has two senators. Originally, senators were appointed by the governor of the state they represented but they are now elected to dish six-year terms. The House of Lords is very different. Members of the House of Lords are not elected. The 792 members of the House of Lords are members by inheritance, appointment or their rank in the Church of England they are not elected and cannot be removed by vote. This part of the political system in the U. K is not democratic. Otherwise the House of Lords serve the same utilisation as the U. S.Senate. They discuss, debate and vote on legislation passed by the lo wer house of the legislative branch. The Lower House The U. S. House of Representatives and the British House of putting green have a great deal in common. Each house is made up of representatives elected by the people. In both systems control of the lower house goes to the party that has the most seats. Under the U. K. system, the leader of the party with the most seats becomes the Prime Minister and the official head of the government. Under the U. S. system this soul would be the Speaker of the House.One other key difference is elections. Under the parliamentary system, the prime minister can go to the crown at any point and ask to dissolve Parliament. If this is done an election is called. An election can also be called if the prime minister loses the confidence of the house. This means that the prime minister lost a vote in Parliament on a matter of confidence. Matters of confidence are usually over budgetary matters. If the prime minister loses a vote of confidence, the end result is an election Other political differences.The American general election lasts almost two years, starting with the declaration of candidates for the primaries. The British general election lasts around four weeks. In the United States, no Cabinet member is allowed to be a member of the Congress because of the strict theory of the separation of the powers. In Britain, every Government Minister must be a member of one of the two Houses of Parliament and, if he or she is not already in the Parliament, he or she is made a peer. The constitutional system in the UK involves a lot of custom and practice, and much more flexibleness than the US system.For example, the timing of US presidential elections is fixed. In the UK, it is essentially the Prime Ministers choice as to when elections are to be held, up to the 5 year limit. The patience of a president in the US would have to lead either to an election or to his vice president taking up the office. In the UK, the forbearance o f a prime minister will lead to the party choosing a new leader, but there is no technically requiring this, the Queen is technically rationalise to choose whoever she wishes.

Human Resources In US Healthcare

Human Resources In US Health apprehensionThe wellness address industry is the largest employer in the United States, in 2002 this industry consisted of 518,000 organizations that employed 12.9 million individuals (Fallon McConnell, 2007). The health electric charge sector employs 10.9% of all employment in the United States and has a 16% new job growth. The reason behind this growth is primarily due to two factors increase in the use of technology and the continued aging of the population (McConnell, 2006). Large numbers of individuals are needed to provide, record, and bill for the services provided to the patients. Human resources are the a reartha of the health organization because they address the need to ensure that each government agency is staffed with qualified and motivated somebodynel (Hernandez, 2009). In strategic military personnel resources supply, the human resources department is an meaning(a) member of the healthcare industry. The HR department is involved in a number of activates that together comprise of four major(ip) activity groupings hiring of employees, maintaining employees, retaining employees, and separating employees.To about people the human resources department is viewed as more administrative than advisory and as an enforcer of policies than the actual policy makers. Basically, people consider this department as where you go to get hired or to file your personal papers. thither are times when other departments may look upon the human resources department negatively and this is due to the fact that other departments may not know the rules and regulations that HR must follow for example a department manager may aim a key position that has been vacant for a few weeks and because of the vacancy the other employees in the department has to work mandatory overtime (Bohlander, Snell, Reviews, 2009) An ideal prospect has been interviewed by the HR department and is because referred to the manager for another interview, the manager then tell HR that this is the exact person they are looking for and they would same(p) this person to start in their department as soon as tomorrow, however, because of the protocols that HR must follow they are not able to hire this person before a soil check, references and a drug test has been done. The manager of the department may then complain to their senior manger that HR is taking their time or is unwilling to cooperate (Bohlander, Snell, Reviews, 2009). in that location are m whatsoever departments within the healthcare field, from different types of physicians, nurses, administration and technicians. In hospitals the human resources has a part in hiring all of these people, in private facilities that is owned by one or two physicians the HR department will in most cases knob everyone except the physicians. Physicians are some of the most important people that work in a hospital they are traditionally the focus of the health care industry. The reason is becaus e they are the people who primarily evaluate and diagnose patients conditions and inflict handling. When it comes to the hiring of a physician, it must be determine that their services will be an addition to the hospital because of their salary related costs. When there is a need for the hiring of a physician, the HR department must make sure he/she is competent, a background check must be preformed and they must make sure they are certify to practice in the state where they are practicing. Physicians must complete internship/ compliance which is a form of paid on the job prep and this is ordinarily done at a hospital. Nurses work closing with physicians because they provide the primary care to the patients in both hospital and clinic settings. The duties of nurses differ depending on the type of setting in which they are working. The different settings that nurses work in areHospitalsNursing main offices occult practiceAmbulatory center centersManaged care organizationWorksite sGovernment and private agenciesClinicsSchoolsRetirement communitiesRehabilitation centersNurses are increasingly being employed by outpatient centers and home healthcare organizations because of the trends toward discharging patients from hospitals faster and effecting many procedures in outpatient settings (Wolper, 2004). When a nurse is hired the human resources department must make sure that the nurse is licensed to practice. A nurses licensure is achieved by graduating from an accredited nursing school and completing a farmingal exam. A physician that does not have a MD or a DO degree are non-physician practitioners, they provide health services in areas similar to those of a physicians. In 47 states and the District of Columbia, they can prescribe medication (Wolper, 2004).Human resources may be recognizable as 5 different models, these are clerical, counseling, industrial relations, control and consulting model. Under clerical model, human resources perform the following du ties processor, file paper, keep records, and track various statistics and key dates and administrator of employee benefits plans. Under this model, the top manager of this department is most likely to be experiences as a benefits administrator or have a similar practitioner orientation. The counseling model is relatively common in hospitals because the total cost of employees represents a large portion of the budge and there is an emphasis on maintaining employees as effective productions. Under this model HR is likely to function as an abet for employees, place high priority on preserving privacy and confidentiality, actively stress training and development and function as a resource to managers for people problems, disputes, and disciplinary issues. The industrial relations model develops in organizations in which the work force is colligationized, and there are periodic contract negotiations and considerable activity having to do with grievances and arbitrations. HR functions specified by contract are performed automatically and as expected, with little room for flexibility or judgment in their performance. The control model find in very few organizations offers the HR department substantial power, under this model little management action is taken without the clearance of HR the HR department is sure and knowledgeable concerning all legal requirements and the HR executive will be a key member of the organizations administrative team. The consulting model is usually found in larger organizations, under this model the HR practitioners are usually expert resources, relied upon by employees, department managers, and executive management according to need. There are alternative models much(prenominal) as managerial model and financial model, under the managerial model the HR has no particular strategic mind-set or long range prep involvement. A HR function operating under the financial model displays maximum attention to HR costs, in particular, indire ct compensation costs such as health and dental insurance, life insurance, retirement plans, paid time off, and other benefits.The human resources department of any healthcare entity must protect and support the quality of the patients kinship with the healthcare entity, but it also must protect and encourage the quality of the employees relationship with the healthcare entity. The employees of the healthcare industry must provide compassion and they should consider care but their job satisfaction is important. The major managerial function surrounding human resources areStrategic PlanningRecruitment and SelectionRetentionCompensation and BenefitsPerformance EvaluationTraining and EducationLegal and Regulatory IssuesStrategic planning is the process of matching the human resources of an tune with its goals and objectives. In strategic HR planning, the human resources department is an important member of the executive committee. Recruitment and selection go away hiring of the bes t candidate with the needed skills. When recruiting people for a new position, it is important to recruit internally as well as externally, because a member of the current staff may be appropriate for the position. It is important that new recruits fit into the organizational horticulture but it is also critical to assess the organizational culture to ensure that it is not a source of retention problems. For example doctors lack of respect for nurses in some organizations has created a retention problem for nurses. The process of recruitment, selection, and training is intensive and expensive, in both actual cost and opportunity costs. High compensation is a factor that will enhance retention of workers, benefits is also important in retention. Performance evaluation is a way to define the level of competence of an employee as measured against a certain standard level of skills and knowledge. To encourage the practice of performance evaluation, many health care organizations, espec ially integrated health care systems are implementing, pay for performance, compensation plans. Pay for performance can be based on individual, tem, organization goals.Human Resources not only have to deal with many challenges such as training and education mandates, health care organizations must be knowledgeable of the legal and regulatory issues related to the HR department in general. This is especially when it deals with safety in the workplace and union regulations, because of the potential for exposure to blood borne pathogens and radiological substance. Health care organization must have appropriate safety measures in place to protect their employee against injury, as well as appropriate training to facilitate the use of these safety measures. Another challenge in HR is planning is very important in the HR department by planning correctly (McConnell, 2006). HR can avoid having a surplus or a shortage. If HR has hired as well as many employees for the health care faculty the n there would be a surplus but it do not hire enough then there would be a shortage. The health care organization is very diverse, diversity means a wider range of people bringing a greater variety of approaches to work, ideas, lifestyles issues and many other things. Human resource policies must address these differences in order to attract, retain, and maximize the contributions of all members of the changing workforce.Human resource planning in the 21st century is a much more comprehensive set of analyses and examinations to ensure that the HR department function optimally contributes to the organizations overall business success. Human resources function is striving toward creating stronger business partnerships within the organization, the need for thorough and accurate HR planning is likely to be unique to each organization. There are equitys that affect different aspects of employment relationship, the human resources department must be aware of these pieces of formula. A s ignificant legislation was the Civil Rights Act of 1964 this legislation marked the beginning of significant changes in relations between the government and business in the United States (McConnell, 2006). Before the Civil Rights Act, businesses were free to treat their employees basically as they chose, there were only two exceptions wage and hour laws and labor relations laws. Prior to 1964, the only laws that had noticeable impact on the employment relationship were the plumb Labor Standards Act and related state laws, and the National Labor Relations Act. Employees payment of wages and other related conditions of employment were governed under the Fair Labor Standards Act (McConnell, 2006). The relationship between work organizations and labor unions were governed under the National Labor Relations Act. The Social Security Act provided low income decrepit people with social insurance. In 1937 this act was expanded to provide benefits to survivors of covered workers who became permanently disabled. The Health Insurance Portability and Accountability Act (HIPAA) went into effect on July 1st, 1997 this law ensures that most persons who change jobs will receive continuous health insurance without regard to many preexisting health conditions (McConnell, 2006).Organization need to consider a variety of issues when analyzing the impact of HIPAA on their organization. Some issues that may impact their organization areHIPAA is about improving the efficiency and cost effectiveness of the healthcare system. exceptional resources, both in terms of dollars, staffing, and timeConvergence of e-health strategies and HIPAA objectives, which are clearly connect in the areas of standardization and technical security measures.Constraining effects of legacy systems within industry, which add to cost of compliance as well as ongoing dependency on vendors.There will be a dim impact on overall healthcare industry electronic communications and transactions HIPAA have pave th e way for increasingly sophisticated e-health and other healthcare e-commerce and communications applications as well as for new uses of evolving technologies, such as hand held devices and wireless access (Fallon, McConnell, 2007).There are a few healthcare industry forecasts that will directly impact job summary. In healthcare technology is ever and quickly changing and such technology makes new procedures and treatment possible. These new treatments and procedures provide a solution that meets medical needs for a number of patients, which leads to an increasing survival rate and the rising life expectancy of the nation as a whole. It is believed that over the next 15 years, there will be a shortage of physicians in the United States. We may also chaffer a similar trend in the supply of nurses. With the demand for quality healthcare increasing by an aging population demanding more health care service, the nursing shortage will be an important strategic human resource issue in t he health care industry (Shi, 2007). Job analysis will play an important role. Since the healthcare industry is forever changing, the idea of strategic job analysis surely will become a major focus on healthcare organizations. Strategic job analysis is the identification and specification of future jobs takes and responsibilities and the knowledge, skills, and abilities needed to perform those jobs that presently do not currently exist but are anticipated to be needed in the future. There should be also be anticipation of the future changes in terms of laws and regulations, employee demographics, profession shortages, technology, information, technology, and other possible changes (Shi, 2007). It is important for human resources to know which jobs and associated tasks will be needed in the future, along with identifying the knowledge, skills, abilities, and other requirements needed to perform such jobs, will be a potential advantage for health care organization desiring to effecti vely compete in the future.

Pediatric Developmental Care Plan

Pediatric Developmental Care PlanRunning Head PEDIATRIC DEVELOPMENTAL typographyPediatric Developmental PaperArlena DavisSubjectiveClarissa is a 3 year old girl with upper respiratory infection. She has always lived with her pa involves and, grandmother in the akin place. Her parents are mainly responsible for raising her since she was born. However, the pip-squeak spends most of the time with her grandmother as the parents go to work. The electric chargegiver described the pip-squeak as calm, playful, calefactive tempered and shy. The grandmother spends more than 8 hours with the child as her parents go to work at 8.00am and come back at 5.00pm. The child wakes up at 8. 00 am and eats her meals with the grandmother. However, the child interacts with her parents during dinner and bedtime. The caregiver and the child interact well as the toddler shows affection by hugging. However, the caregiver identified the childs upsetting behaviors including pushing people when she is angry . The caregiver disciplines the child when she misbehaved or went to breakneck places (Burns et al., 2013).Additionally, the parents worry astir(predicate) the childs recourse at nucleotide since she likes going to self-destructive places. The grandmother finds it challenging to control the childs movement since she is starting to learn about her surroundings. The parents also do not rifle adequate sustainment from family members as they only rely on the childs grandmother. However, they count on few friends for help since they have a long accessible network (Burns et al., 2013). The parents and the grandmother do not spend adequate time with friends, and thus the small tender circle. The father is involved in the care giving role according to the grandmother and the mother. The father is helpful as he assists in feeding the child and playing with her. In addition, the mother did not have complications during pregnancy and the baby was not born premature. The baby was almo st 3.2 kgs and 19 inches at birth. The parents take the child for healthcare at different facilities including indispens adequate to(p)ness rooms and walk-in clinics (Burns et al., 2013).The child has normal growth, appetite, bowel movement, urination and sleep patterns. However, the caregiver claims the child got sick often and she has to call her parents to take her to the hospital. Despite the sickness, the child has managed to learn new words and sounds. The child does not have visual and hearing (Burns et al., 2008). The child interacts well with other people, but the caregiver is worried about the Childs frequent sickness. The family has no major issues and concerns as there is one ill, alcoholic, using drugs or behaving strangely (Provence Apfel, 2001). The family has satisfactory housing and lives in a safe neighborhood. The family does not deal with fear of violence and no one owns a gun. Nonetheless, the family has financial problems and found it challenging to fulfill basic needs like paying rent and bills.ObservationThe child has had normal sodding(a) and motor study from 6 months up to now according to the caregiver (Provence Apfel, 2001). The child was able to sit alone, resist and grasp objects with the index and thumb figure according to the caregiver by 12 months. She could walk independently and scribble with crayon on paper. Additionally, she could build powers of cubes by the age of 18 months and squat and stand at 21 months. Also, she could jump off floor with two feet. She can hold crayon with thumb and finger and duplicate cross on the paper. The child has also had a normal social and turned on(p) development as reported by the caregiver. The child was able to differentiate the main caregiver from other people and establish social contact by smiling by 6 months. She also played social games and enjoyed playing with dolls. She also showed affection to the caregiver and helped her with house chores and organizing things. Neverthel ess, she expressed differ emotions including anger, anxiety and sadness by 12 months. She also found it challenging to fall in while playing with other children. The child has no language development problems as she can speak and answer comprehension questions well. She has coping and self- development issues (Provence Apfel, 2001). She pushes apart unwanted people, diet and objects. On the other hand, she can feed self with a spoon and drink from the cup without assistance. She also helps with dressing. Therefore, the childs gross and fine motor development, language development and coping and self-help development are at age level. The childs social and emotional development is on a lower floor age level.AssessmentClarissa has a normal development in different areas including language, fine and gross motor, coping and self- help development (Provence Apfel, 2001). However, she has an abnormal social and emotional development. She is unable to manage her emotions when playing w ith other children, with the caregiver and other people. She expresses negative emotions including anger and sadness. She pushes away people, objects and foods she does not like. The caregiver and the child interact well as she shows affection to the caregiver by hugging. The child has a positive relationship with the family members including mother and father. Nonetheless, the frequent sickness may affect the childs development as she has upper respiratory infection (Provence Apfel, 2001). The family seeks medical care from the emergency room or walk-in clinics when the child is sick. However, the family concerns include inadequate finances to meet basic needs and safety of the child at home. The child spends most of the time with the grandmother and she is unable to control and prevent the child from going to dangerous places. The family members have a small social network as they do not spend sufficient time with friends. They get financial and social support from the grandmothe r and few friends. The family has no history of alcoholism or fear of violence.PlanThe following interventions will be implemented to address the concerns and issues raised by the caregiver and parents. Improving the safety at home is critical to prevent accidents. In this case, parents and the grandmother will be educated on the importance of safety at home to improve the childs wellbeing. Dangerous substances including poisonous liquids should be stored far from the child to decrease accidents (Burns et al., 2008). The home should be redesigned to eliminate dangerous places and hence promote the childs safety. Adaptations including fireguards and stair gates make the home safe. Further, providing medical care to the child is important to improve her health military issue and quality of life. Different medications will be administered to treat upper respiratory infections including Tylenol, Motrin, Benadryl and cough drugs. Additionally, social support interventions will be provid ed to improve the social wellbeing of the family. Social support interventions are important in increasing social networks or circles and enhancing physical and mental wellbeing (Burns et al., 2013). The parents and the grandmother will be able to share their concerns with friends and get necessary support. Lastly, the child should socialize with caregiver, peers and other adults to develop social and emotional skills. Adults should respond to the childs signals in a reliable and predictable manner to enable her regulate emotions (Burns et al., 2013).ReferenceBurns, C. E., Dunn, A. M., Brady, M.

Anticancer Efficacy of Curcumin Analysis

Anti crabby person Efficacy of Curcumin Analysisnuclear factor-B (NF-B) is a transcription factor that is essential in the regulation of immune and inflammatory responses.1 It influences a diverse target of gene expressions that regulate apoptosis, facilitate cell survival, proliferation, and differentiation.1,2 ahead cell stimulation, NF-B dimers that are located in the cytoplasm are inactive.3 Prior to activation, NF-B dimers consisting of RelA, c-REL, and p50 are held in the cytoplasm by restrictive B (IB) proteins.3,8 The IB kinase (IKK) complex is activated by various extracellular signals such as proinflammatory cytokines and viral infections.3,4 This IKK complex phosphorylates two conserved serine residues and targets NF-B-bound IBs, which firmnesss in ubiquitin-mediated dissociation of IB from NF-B, thus leading to translocation of activated NF-B into the nucleus.2,7 The activation of NF-B promotes tumor invasion, metastasis, and al bases malignant cells to escape apoptos is. Consequently, many chemotherapeutical drugs have been found to activate NF-B, thus contributing to chemoresistance and chemotherapy failure.3 Increasing evidence suggests that, the inhibition of NF-B activation can reduce chemoresistance and improve the effectiveness of chemotherapeutic agents.3Among the compounds that have been reported, curcumin was found to inhibit the activation of NF-B and thus, induce apoptosis in tumor cells.6 Unfortunately, its clinical applications remains hold due to its poor bioavailability and low potency6, these prompted researchers to chemically modify curcumin in order to increase its potency against NF-B and cancerous cells.8In this issue, Qui et al.8 reports progress in the synthesis and identification of new 4-arylidene curcumin analogues as a potential chemotherapeutic agent. Different kinds of 4-arylidene curcumin analogues were synthesized by coupling 1, 3-diketones curcumin analogues with various aromatic aldehydes in toluene with aceti c acid, using piperidine as a particle accelerator (figure 1).The chemotherapeutic activities of the synthesized compounds were tested on the growth of A549 lung adenocarcinoma cells with curcumin used as control. The authors reported that majority of the 4-arylidene curcumin analogues exhibited potent antitumour activities against A549 growth with GI50 in the range of 0.23 0.93 M, term very poor antiproliferation activities of curcumin was observed at 15.23 M. This shows a 10- to 60-fold increase in the potency of 4-arylidene curcumin analogues over the parent compound, curcumin. Remarkably, the cytotoxic activities of these newly designed curcumin analogues were not limited to A549 cells. The growth of other carcinoma cells H1944, squamous cells H157, and large carcinoma cells H460, were effectively hold by selected 4-acrylidene curcumin analogues, with GI50 values at micromolar concentrations low to 0.07 M. Likewise, in a related study, Zambre et al.9 reported that copper(II ) conjugates of Knoevenagel condensates of curcumin analogue showed inhibitory activities against human leukemic KBM-5 cells. Taken together, these two forms of curcumin analogues offer new possibilities at both ends as potential antitumour agents.One of the key curcumin targets that is important for the survival of cancer is IB kinase (IKK), which regulates NF-B activation.6 Activated NF-B is situated in the nucleus to promote transcription that is triggered by tumor-necrosis factor (TNF).1,5 Thus, Qiu et al.8 used nuclear translocation of NF-B in response to TNF as the main indicator to examine the mode of action of curcumin in comparison to 4-arylidene curcumin analogue. A549 cells were treated in a 384-well surface format with curcumin and its new analogue respectively, before the addition of TNF to trigger nuclear translocation of NF-B p65 subunit. As a result, curcumin inhibited TNF-induced nuclear translocation of NF-B with a mean IC50 of 9.5 M, which is consistent with the work of Kasinski et al.4 Interestingly, most of the synthesized 4-arylidene curcumin analogue showed im prove inhibitory activities against NF-B translocation with mean IC50 values in the range of 1.0 4.9 . This finding proved the superiority of the newly designed curcumin analogue over curcumin in blocking nuclear translocation of NF-B. Consequently, in a related paper, Zambre et al.9 developed novel curcumin analogues that were synthesized using Knoevenagel muscle contraction to convert enolic diketones of curcumin into non-enolizable ones. The synthesized compounds were examined for their potential in blocking TNF-induced NF-B activation. It was reported that copper(II) conjugates of Knoevenagel condensates of curcumin showed greater potentials in blocking TNF-induced NF-B activation than curcumin, confirmatory the potency superiority of curcumin analogues over the parental curcumin.NF-B is principally activated by IKK in its well organized signaling pathways.2,7 As a result, Qiu et al.8 favour three potent newly synthesized 4-arylidene curcumin analogues A, B and C to directly investigate their effect on IKK enzymatic activity, with curcumin used as control. Report was given that upon stimulation of A549 cells with TNF, TNF induced considerable IB phosphorylation followed by degradation of the phosphorylated IB. However, following the treatment of the cells with curcumin and its newly designed analogue, respectively, curcumin inhibited IB phosphorylation and degradation at high concentrations, while the selected potent newly synthesized curcumin analogues significantly inhibited IB phosphorylation and degradation at a decline concentration with IC50 values in micromolar range of 2.2 5.0 . Again, this showed that the 4-arylidene curcumin analogues exhibited greater inhibitory activities against IB than curcumin. In another study, Kasinski et al.4 proposed that the inhibitory activities of curcumin and its analogues may be a result of direct inhibitio n of IKK kinase. To examine this model, the authors performed a reconstituted IKK inhibition assay with recombinant IKK, report showed that the addition of curcumin in various tested concentrations had no significant effect in inhibiting IKK.4 However, in this issue8, the selected newly synthesized curcumin analogues induced a dose dependent inhibition of IKK. Thus, the structural modification of these curcumin analogues results to improved inhibitory activities over curcumin in the in vitro IKK kinase assay.Furthermore, they compared the anticancer efficacy of curcumin and its newly designed analogues. The authors reported that the synthesized 4-arylidene curcumin analogues inhibited colony formation of lung cancer cells at low concentrations in the micromolar range of less than 0.2 0.4 M.8 However, curcumin also inhibited colony formation of cancer cells at higher concentration (4 M). Again, this finding showed the superiority in potency of 4-arylidene curcumin analogues over the parent compound as an anticancer agent. Thus, the chemical modification of the parental curcumin has led to identification of new 4-arylidene curcumin analogues as potential anticancer agents targeting NF-B signaling pathway.REFERENCES1 Baud V, Karin M.
