Abstract: objective: the purpose of the study was to assess pharmacists′ current practice, perception and knowledge towards the use of herbal products in abu dhabi, united arab emirates (uae). the study assessed the need for incorporating herbal medicine as a separate topic in under- graduate pharmacy student curricula. methods: the study was done on 600 pharmacists employed in abu dhabi, who were contacted electronically, out of which 271 had completed the survey. the data was collected using a structured questionnaire. results: pharmacists′ use of herbal products is high in the uae, as they have a high belief on the effectiveness of herbal products, and only age was found to be the most predominant variable that was influencing pharmacists′ personal use of herbal products (p-value=0.0171). pharmacists were more knowledgeable on the uses/indications of herbal products (47%) rather than on other areas. knowledge of the dispensing mode (prescription only or over the counter medicines) mandated by the ministry of health was quite good, however, it is to be noted that the source of information on the dispensing mode was provided by medical representatives (48%). knowledge of dispensing mode of herbal products was found to be significantly influenced by the place of work with more knowledge of the dispensing mode by pharmacists working in the private sector (p-value 0.0007). the results from the study also underscores the need for including herbal medicine as a separate topic in pharmacy college curriculum and to provide for more seminars and continuing pharmacy education programs targeting pharmacists in the emirate of abu dhabi. conclusions: pharmacists need to be informed on indications, drug interactions, adverse events and precautions of herbal products. concerned bodies must also provide them with regular continuing education programs apart from putting their efforts to incorporate relevant topics on herbal medicine in the pharmacy students′ curriculum.
Payers endorse generics to enhance prescribing efficiency: impact and future implications, a case history approach
Brian Godman, BSc, PhD,Mohammed Abuelkhair, PharmD,Agnes Vitry, PharmD, PhD,Shajahan Abdu, MD
Generics and Biosimilars Initiative Journal , 2012,
Abstract: Introduction: Pharmaceutical expenditure continues to rise driven by a number of factors including ageing populations and the continued launch of new premium-priced drugs. Increasing use of generics versus originators and patent-protected products of the same or related classes can help conserve valuable resources. However, concerns with their effectiveness and safety compared to originators as well as only limited introduction of measures to promote their demand in some countries have led to variable use among countries. Countries need to learn from each other to further enhance their prescribing efficiency.Study Objectives: Firstly to review successful case histories from different countries, and secondly, raise awareness about potential pitfalls that could undermine the success of future measures in order to provide future guidance on conserving resources in relation to generics. Methods: A narrative review of case histories selected by co-authors using a range of different approaches. Systematic reviews are published elsewhere.Results: Twelve case histories were selected depicting both supply- and demand-side measures. These include Croatia where the introduction of additional measures helped reduce drug expenditure as well as debt whilst improving access to new medicines, Lithuania where recent reforms decreased pharmaceutical expenditure in 2010 whilst the number of prescriptions increased by 9% versus 2009; Scotland where despite a 6.2 fold increase in statin utilisation, multiple measures limited the increase in reimbursed expenditure to just 7% in 2010 vs 2001; Sweden where the introduction of monthly auctions for generics has helped lower prices; and the US where managed care organisations actively encourage cross therapeutic opportunities for generics substitution where the safety and efficacy of a generic drug is similar to a patent-protected product in the class or related class to conserve resources.Conclusion: Payers across Australia, Europe, Middle East (United Arab Emirates), and US have introduced multiple measures to both enhance the prescribing of generics and obtain lower prices, with the result that they are increasingly able to take advantage of the availability of generics. However, due to growing pressures on healthcare resources, it is important that countries accelerate the sharing of lessons learned about which policies and new measures are most effective in controlling costs.

Pharmacists were more knowledgeable on the uses/indications of herbal products (47%) rather than on other areas. Knowledge of the dispensing mode (prescription only or over the counter medicines) mandated by the Ministry of Health was quite good, however, it is to be noted that the source of information on the dispensing mode was provided by medical representatives (48%). Knowledge of dispensing mode of herbal products was found to be significantly influenced by the place of work with more knowledge of the dispensing mode by pharmacists working in the private sector (p-value 0.0007). The results from the study also underscores the need for including herbal medicine as a separate topic in pharmacy college curriculum and to provide for more seminars and continuing pharmacy education programs targeting pharmacists in the Emirate of Abu Dhabi.Conclusions: Pharmacists need to be informed on indications, drug interactions, adverse events and precautions of herbal products. Concerned bodies must also provide them with regular continuing education programs apart from putting their efforts to incorporate relevant topics on herbal medicine in the pharmacy students’ curriculum.

Mohammed O. Mohammed
International Journal of Clinical Medicine (IJCM) , 2014, DOI: 10.4236/ijcm.2014.519151
Abstract: Background: Helicobacter pylori is the most common chronic bacterial infection, and a significant etiological factor in acid peptic diseases and gastric cancer. Dyspepsia is a common gastrointestinal disorder, and the most common indication for gastroscopy. Detection of H. pylori during endoscopy has become standard clinical practice. Elevated levels of inflammatory markers such as C-reactive protein (CRP), are associated with pathological changes, and hence give useful information for exact diagnosis and therapy. Objectives: To determine the relationship between endoscopic findings, highly sensitive C-reactive protein level (hs-CRP) and H. pylori infection among dyspeptic patients using serological tests, stool antigen for H. pylori and antral histology. Methods: This was a prospective study; patients with dyspepsia, who referred to Kurdistan Teaching Center of Gastroenterology & Hepatology in Sulaimani City were assessed, during the period of December 2012 to March 2014. They underwent gastroscopy, and biopsies were taken from the corpus and antral portions of antral portion for histopathological exam. Patients’ serum samples were tested for H. pylori infection using ELISA method to detect (IgG & IgA) anti-bodies and stool samples were examined using rapid immunoassay method to detect H. pylori antigens. hs-CRP was assessed using ELISA. Results: One hundred dyspeptic patients were included in the study. The mean age was 34.2 years and male comprised 54% of the study samples. The common findings in oesophagogastroduodenoscopy (OGD) examination were antral gastropathy (59%) and duodenal ulcer (21%). A statistically significant (P < 0.01) correlation was found between hs-CRP and H. pylori IgG and IgA levels (titer). There was a highly significant (P < 0.01) correlation between the level of H. pylori IgG and the endoscopic findings. The highest serum level of H. pylori IgG was found in duodenal ulcer and antral gastritis, (88.86 ± 42.0) and (70.05 ± 35.2) Au/ml, respectively. There was a highly significant correlation (P < 0.01) between endoscopic findings and H. pylori positive antral biopsy, in duodenal ulcer, antral gastritis and duodenitis was 100%, 94.9% and 75% respectively. Also duodenal ulcer and antral gastritis showed high mean and percentage but no significant differences in both H. pylori IgA and stool Antigen.

Applied Mathematics (AM) , 2012, DOI: 10.4236/am.2012.38130
Abstract: The paper deals with the existence of nonzero periodic solution of systems, where k∈(0, π/T), α, β are n×n real nonsingular matrices, μ=(μ1…μn), f(t, u)=(f1(t, u),…,fn(t, u))∈C([0, T]×□n+,□+) is periodic of period T in the t variable are continuous and nonnegative functions. We determine the Green’s function and prove that the existence of nonzero periodic positive solutions if one of . In addition, if all i=(1…n)where λ1 is the principle eigenvalues of the corresponding linear systems. The proof based on the fixed point index theorem in cones. Application of our result is given to such systems with specific nonlinearities.

Agricultural Sciences (AS) , 2013, DOI: 10.4236/as.2013.47046
Abstract:

Citruses are the worlds’ second fruit crops by volume next to banana. It is one of the most important commodity in tropical Africa as source of foreign currency, raw material for agro-industries and source of employment. The production and productivity of citrus in tropical Africa including Ethiopia are critically threatened by a number of diseases. Among others, pseudocercospora leaf and fruit spot of citrus caused by a fungus Pseudocercospora angolensis is the most destructive disease of citrus. Literature reviews have been made by searching the available information on leaf and fruit spot of citrus. Journal articles, research papers, workshop proceedings, Thesis research, manuals, and quarantine regulations were among the information sources of the review. The disease is widespread in 22 African countries including Ethiopia with a single report around Yemen in the Arabian Peninsula. Scattered research efforts have been made by different researchers in Africa mainly dealing with its geographic distribution, biology, and management practices. Fungicides, plant extracts/essential oils, and host resistance are among the research efforts made for the control of P. angolensis. Even though the disease is not yet reported to the rest of the world, it becomes a serious concern as an important quarantine pest thereby critically affecting the world trade and germplasm exchange of the citrus industry. Therefore, the purpose of this paper is to compile the scattered information on various aspects of leaf and fruit spot of citrus mainly to avail the information for researchers, development workers and policy people. Moreover, this review will suggest future research and development direction towards better understanding and sustainable management practices of the disease.

Variation of the Spectrum of Operators in Infinite Dimensional Spaces  [PDF]
Mohammed Yahdi
Advances in Pure Mathematics (APM) , 2013, DOI: 10.4236/apm.2013.37080
Abstract:

The paper investigates the variation of the spectrum of operators in infinite dimensional Banach spaces. Consider the space of bounded operators on a separable Banach space when equipped with the strong operator topology, and the Polish space of compact subsets of the closed unit disc of the complex plane when equipped with the Hausdorff topology. Then, it is shown that the unit spectrum function is Borel from the space of bounded operators into the Polish space of compact subsets of the closed unit disc. Alternative results are given when other topologies are used.

A New Expression for Rhotrix  [PDF]
Abdul Mohammed
Advances in Linear Algebra & Matrix Theory (ALAMT) , 2014, DOI: 10.4236/alamt.2014.42011
Abstract:
This paper presents a new technique for expressing rhotrices in a generalize form. The method involves using multiple array indexes as analogous to matrix expressions, unlike the earlier method in the literature, which can only be functional in a single array computational environment. The new rhotrix look will encourage the study of rhotrix algebra and analysis from a better perspective. In addition, computing efficiency and accuracy will also be improved, particularly when the operations in rhotrix space over the new expression are algorithmatized for computing machines.

American Journal of Climate Change (AJCC) , 2015, DOI: 10.4236/ajcc.2015.44027
Abstract: In order to provide a better benchmark for climate simulation programs, climate data at Global Historical Climatology Network (GHCN) and Global Summary of the Day (GSOD) archived by the National Climate Data Center (NCDC) are used to ascertain the nature of climate change over the last century. After data validation, about 6000 stations are considered globally to determine the change in mean temperature, and about 5000 stations to determine that change in maximum and minimum temperatures. Global nature of temperature and its change are presented separately for January and July. Both maximum and minimum daily temperatures are used in the analysis. Trend of global change in annual precipitation is also reported here. Least square linear regression is used to ascertain the nature of these changes. Global nature of temperatures in both January and July show bimodal distributions, with the geographical region between the tropics in one mode and the region outside the tropic in another mode. The individual distributions of temperatures of both these regions show separate and similar histograms. Results indicate that over the last century, temperature in January increased more than that during July. Furthermore the minimum temperature in each case increased more than the maximum temperature. Ten separate estimates of temperature change are obtained from the data presented here using different methods. Considering all these estimates, the mean rise in temperature during January was 2.19°C, and during July was 1.72°C. The geographical nature of the rise in temperature shows that though it rises in most locations, the temperature also reduces along eastern Asia, some parts of central Russia, along south-eastern Australia, and along the east coast of the United States. Predominant rise in temperature is mostly over Europe, and in the arctic. Change in precipitation shows that though there is significant reduction rainfall globally, rainfall increases along the equator, in areas around the Gulf of Mexico, along eastern Asia, along the western coast of India, and along the eastern coast of Australia.

Mohammed Mansur
Journal of Applied Mathematics and Physics (JAMP) , 2015, DOI: 10.4236/jamp.2015.38125
Abstract:

The objective of the present experimental work is to investigate the performance of a wrapped screen heat pipe for atmospheric air heating to compare with the limits of this pipe. The experiment was conducted using copper pipe material and acetone as working fluid at different vapor temperatures. The testing also consists of a heater, a blower for heat removal (condenser), temperature measuring device, a vapor temperature probe, acetone charging system, and a vacuum pump. The copper outside diameterof the pipe is 0.022 m, with a total length of 0.6 m. The results showed that the pipe wall temperature (Tw) for a wrapped screen heat pipe has a rapid increase and takes 50 min to reach steady state at (Q = 63 W). The vapour temperature of working fluid increases as the heat load increases at constant air velocity. It was also been found that the range of vapour temperature deceases as the filling ratio increases that means the increasing of the filling ratio results the decrease of the maximum vapour temperature and the variation in the vapour temperature. The best recorded filling ratio is 0.6 which has the lowest vapour temperature at highest heat load. The maximum heat transport limit for this pipe is 80 W and the maximum temperature difference for air is 5C.
