All manuscripts submitted to Global Journals should include: Title the title page must carry an informative title that reflects the content, a running title (less than 45 characters together with spaces), names of the authors and co-authors, and the place(s) where the work was carried out. By optimizing your paper for search engines, you will amplify the chance of someone finding it. Keywords A major lynchpin of research work for the writing of research papers is the keyword search, which one will employ to find both library and internet resources. Up to eleven keywords or very brief phrases have to be given to help data retrieval, mining, and indexing. Ask, "What words would a source have to include to be truly valuable in a research paper? Tables, Figures, and Figure Legends Tables: Tables should be cautiously designed, uncrowned, and include only essential data. Color charges: Authors are advised to pay the full cost for the reproduction of their color artwork. Hence, please note that if there is color artwork in your manuscript when it is accepted for publication, we would require you to complete and return a Color Work Agreement form before your paper can be published. Also, you can email your editor to remove the color fee after acceptance of the paper. This may be done by asking several questions of yourself, like "Will I be able to carry out a search in this area? Think like evaluators: If you are in confusion or getting demotivated because your paper may not be accepted by the evaluators, then think, and try to evaluate your paper like an evaluator. Try to understand what an evaluator wants in your research paper, and you will automatically have your answer. Make blueprints of paper: the outline is the plan or framework that will help you to arrange your thoughts. But remember that all points of your outline must be related to the topic you have chosen. Use of computer is recommended: As you are doing research in the field of medical research then this point is quite obvious. If you are not capable of judging good software, then you can lose the quality of your paper unknowingly. There are various programs available to help you which you can get through the internet. If you have all the required books, place importance on reading, selecting, and analyzing the specified information. Use big pictures: You may use encyclopedias like Wikipedia to get pictures with the best resolution. Bookmarks are useful: When you read any book or magazine, you generally use bookmarks, right? Revise what you wrote: When you write anything, always read it, summarize it, and then finalize it. Make every effort: Make every effort to mention what you are going to write in your paper. Polish your work with good writing skills and always give an evaluator what he wants. Produce good diagrams of your own: Always try to include good charts or diagrams in your paper to improve quality. Using several unnecessary diagrams will degrade the quality of your paper by creating a hodgepodge. Pick a good study spot: Always try to pick a spot for your research which is quiet. In a research paper, do not start sentences with conjunctions or finish them with prepositions. When writing formally, it is advisable to never split an infinitive because someone will (wrongly) complain. Arrangement of information: Each section of the main body should start with an opening sentence, and there should be a changeover at the end of the section. Divide your research work into parts, and do a particular part in a particular time slot.

In 1939 he and Felix Bloch made the first measurement of the magnetic moment of the neutron, a characteristic of the strength and direction of its magnetic field. Alvarez worked on microwave radar research at the Massachusetts Institute of Technology, Cambridge (194043), and participated in the development of the atomic bomb at the Los Alamos Scientific Laboratory, Los Alamos, N. He also participated in the development of microwave beacons, linear radar antennas, the ground-controlled landing approach system, and a method for aerial bombing using radar to locate targets. In this accelerator, electric fields are set up as standing waves within a cylindrical metal 300 7 Luis W. The electric field is zero inside the drift tubes, and, if their lengths are properly chosen, the protons cross the gap between adjacent drift tubes when the direction of the field produces acceleration and are shielded by the drift tubes when the field in the tank would decelerate them. The lengths of the drift tubes are proportional to the speeds of the particles that pass through them. In addition to this work, Alvarez also developed the liquid hydrogen bubble chamber in which subatomic particles and their reactions are detected. They postulated that the iridium had been deposited following the impact on Earth of an asteroid or comet and that the catastrophic climatic effects of this massive impact caused the extinction of the dinosaurs. Courtesy of the this widely publicized Lawrence Radiation Laboratory, theory gradually gained the University of California, Berkeley 301 7 the 100 Most Influential Scientists of All Time 7 support as the most plausible explanation of the abrupt demise of the dinosaurs. June 7, 1954, Wilmslow, Cheshire) B ritish mathematician and logician Alan Mathison Turing made major contributions to mathematics, cryptanalysis, logic, philosophy, and biology and to the new areas later named computer science, cognitive science, artificial intelligence, and artificial life. The Entscheidungsproblem seeks an effective method for deciding which mathematical statements are provable within a given formal mathematical system and which are not. In 1936 Turing and Church independently showed that in general this problem has no solution, proving that no consistent formal system of arithmetic is decidable. At the outbreak of hostilities with Germany in September 1939, he joined the wartime headquarters of the Government Code and Cypher School at Bletchley Park, Buckinghamshire. The British government had just been given the details of efforts by the Poles, assisted by the French, to break the 303 7 the 100 Most Influential Scientists of All Time 7 Enigma code, used by the German military for their radio communications. As early as 1932, a small team of Polish mathematician-cryptanalysts, led by Marian Rejewski, had succeeded in reconstructing the internal wiring of the type of Enigma machine used by the Germans, and by 1938 they had devised a code-breaking machine, code-named Bomba (the Polish word for a type of ice cream). The Bomba depended for its success on German operating procedures, and a change in procedures in May 1940 rendered the Bomba virtually useless. During 1939 and the spring of 1940, Turing and others designed a radically different code-breaking machine known as the Bombe. By early 1942 the Bletchley Park cryptanalysts were decoding about 39,000 intercepted messages each month, which rose subsequently to more than 84,000 per month. At the end of the war, Turing was made an officer of the Order of the British Empire for his code-breaking work. Turing 7 honour that went to the Royal Society Computing Machine Laboratory at the University of Manchester in June 1948. His earlier theoretical concept of a universal Turing machine had been a fundamental influence on the Manchester computer project from its inception. Artificial Intelligence Pioneer Turing was a founding father of modern cognitive science and a leading early exponent of the hypothesis that the human brain is in large part a digital computing machine. He theorized that the cortex at birth is an "unorganised machine" that through "training" becomes organized "into a universal machine or something like it. In March 1952 he was prosecuted for homosexuality, then a crime in Britain, and sentenced to 12 months of hormone "therapy"-a treatment that he seems to have borne with amused fortitude. Judged a security risk by the British government, Turing lost his security clearance and his access to ongoing government work with codes and computers. He spent the rest of his short career at the University of Manchester, where he was appointed to a specially created readership in the theory of computing in May 1953. He wrote "The Chemical Basis of Morphogenesis," which described some of his research on the development of pattern and form in living organisms, and he used the Ferranti Mark I computer to model chemical mechanisms by which genes could control the development of anatomical structure in plants and animals. In the midst of this groundbreaking work, Turing was discovered dead in his bed, poisoned by cyanide. A homemade apparatus for silver-plating teaspoons, which included a tank of cyanide, was found in the room next to his bedroom.

T h e y all h a d a skin condition (eczema) w h i c h was presumably sufficiently intractable to have reached a specialist clinic. Concern about potentially more serious side effects has recently centred on the topical corticosteroids and the possible deliterious effects w h e n used in large quantities over long periods of time. Thus, fears have been expressed that suppression of natural corticosteroid production m a y take place as a result of absorption of topical corticosteroids through the skin. Also, there have been reports of skin atrophy on the face, and the appearance of striae on the thighs, a m o n g people taking topical corticosteroid medication over long periods of time. In these circumstances it might be anticipated that the side effects of corticosteroids would be both c o m m o n and unrecognised until they reached an advanced stage. W h e n atrophy of the skin occurs it is reversible and there is strong evidence that fears over natural corticosteroid suppression are exaggerated. T h u s Wilson et al (1973) found that in two reasonably comparable groups of patients 96 per cent of those w h o were being treated with halogenated topical corticosteroids had plasma corticosteroid levels of more than 6 mg/100 ml (the conventional lower limit of the normal) compared w i t h 99 per cent of the control group but concluded that such adrenal suppression as does occur is likely to be transient. N o correlation could be found between corticosteroid levels and duration of treatment. If only a very small proportion of these patients had plasma corticosteroid levels below normal limits, and then probably only transiently, it is highly unlikely that many clinically important cases of adrenal suppression are occurring in the less resistant skin conditions dealt with in general practice. There is also some suggestive evidence of teratogenic effects based on foetal abnormalities among animals exposed to corticosteroids. T h e decision illustrates the dilemma in which the Committee on Safety of Medicines must often find itself placed. T h e problem is to balance the benefits against the detrimental effects and it is understandable that when the possibility of teratogenicity is raised, however remote it might be in the particular case, the committee will take the path of caution until evidence is obtained to show that no risk exists. Other physical agents, however, are valuable in what is more clearly recognised as dermatology, including ultra violet rays for the treatment of psoriasis and acne and to promote healing of burns, ulcers, and wounds. Freezing with carbon dioxide snow has been widely used for naevi, warts and rodent ulcers while liquid nitrogen is used particularly for warts. Dermabrasion (or plastic planing) is another technique used in dermatology, mainly to lessen the unsightliness of raised scars, especially in acne vulgaris. Electrocautery is used for destroying small lesions while f i g u r a tion and coagulation can be achieved with the special electric currents used in diathermy. First, there is still often a stigma attached to skin conditions, an association with uncleanness. Skin disorder may also give rise to acute embarrassment, as for example with psoriasis or eczema, or among people given to excessive blushing and sweating. In these cases psychotherapy may be useful in helping people to live with their condition, though, in the primary medical care situation, there are likely to be cases requiring very delicate j u d g e m e n t w h e n the doctor wonders whether he ought to intervene on his o w n initiative. Second, it is claimed that m a n y skin conditions h a v e psychological causes, and b y inference, that psychotherapy c a n cure or alleviate these conditions.

These laboratory capabilities are significant, as many countries continue to lack access to certification quality surveillance for polio eradication or measles/ rubella elimination. This Public Health Reports / 2014 Supplement 3 / Volume 129 Recommendations 37 number is not sufficient to meet the programmatic demands of the polio eradication efforts. Then, on February 8, 2013, attacks on clinics in Northern Nigeria resulted in the deaths of nine polio vaccine workers just after the end of a four-day polio vaccination campaign. For instance, two-thirds of the total measles deaths averted are a result of measles immunizations administered through routine programs. For example, one in every five children continues to go unvaccinated against measles. Strategies such as better data collection and enhanced surveillance activities will improve the quality of existing programs and will translate to more children receiving the full benefits of immunization. Importantly, strong routine systems can serve as a platform for delivering other health interventions. Immunization coverage monitoring and disease surveillance Global health experts have argued that ". The performance of a national immunization program is evaluated both by monitoring the accuracy and reach of vaccine coverage and by measuring the impact the program has had on reducing the disease burden within a population. Surveillance can also help determine whether the major contributor to disease is failure to vaccinate or vaccine failure. If failure to vaccinate is a contributor to disease, then improving vaccine uptake would be the focus of interventions. If vaccine failure is a contributor to disease, then changes in the immunization schedule. Official coverage estimates are often based on administrative data of doses administered in clinics divided by estimates of the target population to be vaccinated. Data regarding the number of vaccine doses administered are collected by national governments via local public health authorities in the course of routine and cam- Public Health Reports / 2014 Supplement 3 / Volume 129 Recommendations 39 paign immunization program work. However, methodologies for collecting both administrative and survey data are often problematic,113 and recent analyses have unveiled persistent discrepancies between coverage estimates based on officially reported administrative data and data collected through household surveys by international organizations. Another criticism of administrative data is the potential for donor funding to influence officially reported immunization coverage. However, establishing immunization registries at the national or district level does not necessarily require the creation or uptake of new and expensive technologies to strengthen data gathering efforts. For example, the country of Oman successfully sustained immunization coverage of 98% for 10 years using a paper-based registry.

Advance innovation in use of biomarkers, technology, and triangulation · Consideruseofavailablebiomarkerstoassesscoveragedatadiscrepanciesand impact, while accelerating investment of future biomarker technologies. This information is sometimes supplemented by parental recall136 (or replaced by parental recall if no immunization card is available). At the household level, research has shown that the methodology used to collect information from families can be problematic. Household survey data quality might be improved by increasing the publicity, promotion, and availability of immunization cards and improving communication between parents and health-care providers about what immunizations are being given and how many doses are needed. The cost of this approach could be minimized by using dried blood spots, saliva, or a random subsample in conjunction with immunization cards and parental recall. The comparison of the antibody titers with immunization cards and parental recall would also provide valuable information. Mobile and digital technologies are also being explored as a user-friendly way to improve field data collection. They then work with government and public health officials to formulate action plans to address those gaps. For example, global polio eradication goals and regional goals for measles/rubella elimination require certification-standard surveillance to verify when endemic transmission has been successfully interrupted. On the other hand, disease-specific initiatives have also led to fragmented, duplicative efforts that result in missed opportunities to coordinate information sharing and maximize limited resources. Resources required for adequate surveillance and program monitoring are minimal compared with program costs of implementing immunization programs. These small investments make the public health system more effective and efficient, resulting in cost savings.

To be protective against acute gastrointestinal effects of copper and provide an adequate margin of safety in populations with normal copper homeostasis 0. Staining of laundry and sanitary ware occurs at copper concentrations above 1 mg/litre. In most instances where copper tubing is used as a plumbing material, concentrations of copper will be below the guideline value. However, there are some conditions, such as highly acidic or aggressive waters, that will give rise to much higher copper concentrations, and the use of copper tubing may not be appropriate in such circumstances. This evaluation was based solely on studies of gastrointestinal effects of copper-contaminated drinking-water. The available data on toxicity in animals were not considered helpful in establishing the upper limit of the acceptable range of oral intake due to uncertainty about an appropriate model for humans, but they help to establish a mode of action for the response. The data on the gastrointestinal effects of copper must be used with caution, since the effects observed are influenced by the concentration of ingested copper to a greater extent than the total mass or dose ingested in a 24-h period. Recent studies have delineated the threshold for the effects of copper in drinking-water on the gastrointestinal tract, but there is still some uncertainty regarding the long-term effects of copper on sensitive populations, such as carriers of the gene for Wilson disease and other metabolic disorders of copper homeostasis. In the first edition of the Guidelines for Drinking-water Quality, published in 1984, a guideline value of 1. The guideline value was considered provisional because of the uncertainties regarding copper toxicity in humans. This guideline value was retained in the addendum to the Guidelines published in 1998 and remained provisional as a result of uncertainties in the doseresponse relationship between copper in drinking-water and acute gastrointestinal effects in humans. Copper can also give rise to taste problems at concentrations above 5 mg/litre and can stain laundry and sanitary ware at concentrations above 1 mg/litre. Geneva, World Health Organization, International Programme on Chemical Safety (Environmental Health Criteria 200). It is used as a pre- and post-emergence herbicide for the control of annual grasses and broadleaf weeds. The mechanism of mammary gland tumour development in SpragueDawley rats is currently under investigation and may prove to be hormonal (cf. Cyanazine is also teratogenic in Fischer 344 rats at dose levels of 25 mg/kg of body weight per day and higher. In the first edition of the Guidelines for Drinking-water Quality, published in 1984, no guideline value for triazine herbicides, which include cyanazine, was recommended after a detailed evaluation of the compounds. Cyanazine was not evaluated in the second edition of the Guidelines for Drinking-water Quality, published in 1993.

It is a reaction product of organic precursors with hypochlorous acid in the presence of ammonium ion. Concentrations detected in drinking-water treated with chlorine and chloramine were 0. There are few data on the oral toxicity of cyanogen chloride, and the guideline value is based, therefore, on cyanide. The guideline value is 70 mg/litre for cyanide as total cyanogenic compounds (see Cyanide in section 12. The 1993 Guidelines derived a health-based guideline value for cyanogen chloride based on cyanide, as cyanogen chloride is rapidly metabolized to cyanide in the body and as there are few data on the oral toxicity of cyanogen chloride. The results of these studies, however, are inconsistent; the associations found are weak, and conflicting conclusions have been reached by the investigators. Most of the studies did not provide information on exposure specifically to 2,4-D, and the risk was related to the general category of chlorophenoxy herbicides, a group that includes 2,4,5-trichlorophenoxyacetic acid (2,4,5-T), which was potentially contaminated with dioxins.

His condition, therefore, represents an emergency best handled either by careful endotracheal intubation under direct bronchoscopic guidance, and/or immediate transfer to the operating theater for bronchoscopic resection. Keeping the patient seated helps maintain airway patency (versus the reclined position). Keeping the patient awake and not sedated helps retain his capacity to cough in order to clear secretions as needed. Careful technique will be required to avoid significant bleeding and further airway obstruction. It is likely this tumor can be removed in toto, although it may be necessary to insert an airway stent, which might be placed at the 163 time of the initial procedure, or at a later date if needed. After the procedure, the patient is best served by hospitalization in the intensive care unit for further stabilization. A 72-year-old woman with unresectable esophageal cancer is admitted to the Intensive Care Unit with bilateral lower lobe pulmonary infiltrates, and suspected aspiration pneumonia based on history. This is the second time in three weeks that she is admitted to the hospital, and her condition appears to be worsening. You decide to perform flexible bronchoscopy as part of the critical care evaluation. Recurrent aspiration is a frequent symptom, and if the tumor is impinging on the esophagus, will also cause increasing dysphagia. Prior radiation therapy is the most common risk factor for esophago-respiratory fistulas. Palliative treatment might include insertion of an esophageal stent, and in some cases, insertion of both an esophageal and airway stent depending on symptoms, and whether there is evidence of central airway obstruction (1-5). Mediastinal adenopathy from Tuberculosis can erode into the airway, especially at the level of the carina and subcarina, but usually, there is evidence of white, creamy, caseating material and a history of tuberculosis. Airway and Esophageal Stenting in Patients with Advanced Esophageal Cancer and Pulmonary Involvement. Please send us your opinion regarding Bronchoscopy Education Project materials by contacting your national bronchology association or emailing us at Question 1: Bronchoscopy is expected to change management decisions in approximately 50% of patients with neutropenia and pulmonary infiltrates. Question 2: Bronchoscopy can be expected to provide diagnostic information in more than 60% of oncologic patients with acute respiratory failure. Question 4: Bronchoscopy may reveal acute lung injury, infection, colonization, airway strictures, or rejection in up to 70% of critically ill lung transplant recipients. Question 6: Lidocaine overdose-related seizures (as part of bronchoscopy topical anesthesia) is most likely in critically ill elderly patients with liver disease. Question 7: Clopidogrel should be stopped at least 5-7 days prior to bronchoscopy with bronchoalveolar lavage in critically ill patients. Question 8: Fentanyl and midazolam are choice agents for moderate sedation in critically ill patients because of their rapid onset of action, rapid time to peak effect, and short duration of action. Question 9: Flexible bronchoscopy is warranted in all patients with suspected or witnessed inhalation injury. List the indications for bronchoscopy in inhalation and burn victims and describe at least three possible bronchoscopic findings with subsequent management. Enumerate five rules for evaluating patients with a known or suspected difficult airway. Describe at least five laryngeal or subglottic airway abnormalities that might represent a difficult airway warranting awake intubation or deployment of a specialized multidisciplinary difficult airway management team. The tip of the bronchoscope is in the midtrachea and you are able to visualize normal appearing vocal cords upon scope insertion. Which of the following is the best maneuver to proceed with successful intubation? Without moving the flexible bronchoscope, withdraw the endotracheal tube slightly, then rotate it 90 degrees counterclockwise or clockwise in order to reverse the locations of its beveled end and Murphy eye.
