The Institute of Ismaili Studies

The Institute of Ismaili Studies (IIS) aims at promoting scholarship and learning on Islam in the context of civilizational studies in general. Utilizing all relevant modern disciplines, it encourages research into Islamic history, with particular reference to its significance for the Muslim societies in contemporary times. While the IIS' interests encompass the Muslim world as a whole, it pays particular attention to Shi'ism and to Ismailism due to the relative neglect of these fields in modern Islamic scholarship

Expression of hepatocyte growth factor and its receptor c-met, correlates with severity of pathological injury in experimental alcoholic liver disease.

Expression of hepatocyte growth factor (HGF) and its receptor, c-met is up-regulated in various forms of liver injury. This study evaluated the relationship between HGF and c-met expression and pathological changes in experimental alcoholic liver disease. Rats (5 per group) were fed ethanol and a diet containing saturated fat corn oil or fish oil by intragastric infusion. Dextrose isocalorically replaced ethanol in controls. In a second set of experiments, Kupffer cells, endothelial cells and hepatocytes were isolated from rats in each group. Pathological evaluation and analysis of HGF and c-met expression were performed in liver and the different cell types. Increased expression of HGF and c-met expression was detected in the liver of rats showing necroinflammatory changes. The Kupffer and endothelial cells were primarily responsible for the increase in HGF, c-met expression was seen only in hepatocytes. Thus, up-regulation of HGF and c-met occurred in the presence of the necrosis and inflammation suggesting that HGF may be acting to protect against liver injury or accelerate the regenerative process

The way forward to public health in Gulf Cooperation Council (GCC) countries: a need for public health systems and law

Introduction: Public health systems in the Gulf Cooperation Council (GCC) Countries are not well established. The existing systems do not match with the current health challenges and with the use of innovative technology in healthcare (diagnosis, treatment or rehabilitation). This paper is intended to give an overview of the public health situation in these countries. It discusses the need for effective and integrated system of public health laws that plays important role in addressing high priorities in public health. Conclusion: The GCC countries have the infrastructure for estab¬lishing a national public health system. However it needs an effective integrated and organized mechanism to shape this system; based on acceptable guidelines and criteria in such a way that they are institutional and capable of meeting the population needs. This system should be cost- effective and investment in health sector should be looked upon as a sustained investment in human and societal development. Despite the great efforts exerted and achievements made, there are great challenges ahead that can be overcome by exhibiting a strong political will and having a united approach of all stakeholders

Health promotion, disease prevention and periodic health checks: perceptions and practice among family physicians in eastern Mediterranean region

Introduction: The aim of this study was to identify the current practices and perceptions of family physicians regarding health promotion, disease prevention including periodic screening and health checks in Eastern Mediterranean Region. Methods: A multi-country cross-sectional study was conducted in six countries of EMR, from September 2014 to March 2015. Family Physicians who were currently practicing in different countries of EMR were invited to participate in the study through email. A pre-tested structured questionnaire was used for data collection. Data was entered and analyzed on SPSS 19 and logistic regression analysis was performed. Results: A total of 100 physicians data was included in the final analysis. The majority were female physicians (76%): 63% were 25 to 35 years of age. Approximately 53% of Family physicians always recommend periodic screening and health checks to their patients. The common screening question asked to patients in medical history was related to their blood pressure (86%). Almost all (99%) of the Family physicians believe they should conduct periodic health checks. Those who had postgraduate training in Family Medicine (OR: 0.5; 95% CI: 0.39-1.67) and attended CME sessions regularly (OR: 0.11; 95% CI: 0.01-0.93), are more likely to recommend periodic screening and health checks to their patients. Conclusion: Periodic screening and health check is an important strategy to prevent disease and maintain health. It is an underutilized practice and a great need exists for its implementation in family practice

Perioperative antibiotics for prevention of acute endophthalmitis after cataract surgery

Endophthalmitis is a severe inflammation of the anterior or posterior (or both) chambers of the eye that may be sterile or associated with infection. It is a potentially vision-threatening complication of cataract surgery. Prophylactic measures for endophthalmitis are targeted against various sources of infection

Toll-like receptor-2 deficiency enhances non-alcoholic steatohepatitis

<p>Abstract</p> <p>Background</p> <p>Previously we reported that mice deficient in toll-like receptor 4 (TLR-4) signalling were protected from diet-induced non-alcoholic steatohepatitis (NASH). Another member of the toll-like receptor family, TLR-2, has been shown to play a role in lipid trafficking via uptake of diacylated lipoproteins. However, a role for TLR-2 in NASH has not been elucidated. The objectives of the current study were to examine the influence of dietary fat quality and TLR-2 on NASH pathogenesis.</p> <p>Methods</p> <p>Steatohepatitis was induced in male Db, C57BL/6 and TLR-2^-/-mice by feeding an L-amino acid-defined diet that was deficient in methionine and choline (MCDD). Mice fed the base diet supplemented with methionine and choline (control diet; CD) were used as controls. To determine the role of fat quality, MCDD was enriched with polyunsaturated corn oil (PUFA) or coconut oil that is comprised mostly of saturated fat (SAFA); the total amount of each fat was 112.9 g/kg of diet. After 8 weeks of feeding CD or MCDD, hepatic steatosis, inflammation and necrosis were evaluated in histological sections. Total RNA was extracted from frozen liver samples and mRNA expression of TNFα, collagen α1, IL-10, peroxisome proliferator-activated receptor-γ (PPAR-γ), TLR-4, and CD14, was analyzed via real-time PCR. Protein levels of TLR-2 were analyzed by western blot.</p> <p>Results</p> <p>Panlobular macrovessicular steatosis and diffuse leukocyte infiltration were noted in PUFA-fed Db mice. Histological scores demonstrated significantly less steatosis, inflammation and necrosis in SAFA-fed mice of all mouse strains. However, compared to wild type mice, hepatocellular damage was notably more severe in TLR-2^-/-mice. Consistent with histological findings, mRNA expression of TNFα was elevated by approximately 3-fold in TLR-2^-/-mice; PPAR-γ expression was blunted in this strain compared to wild type. Expression of the matrix protein collagen αI was also significantly higher in TLR-2^-/-mice, indicating a pro-fibrogenic state. Sensitivity to steatohepatitis due to dietary fat or TLR-2 deficiency correlated significantly with alterations in the expression of TLR-4 as well as the co-receptor CD-14.</p> <p>Conclusions</p> <p>Our findings suggest that dietary saturated fat plays a protective role against MCDD-induced steatohepatitis, whereas TLR-2 deficiency exacerbated NASH. The mechanism underlying the response to dietary fat and TLR-2 likely involves altered signalling via the TLR-4 pathway.</p

Arginine Reverses Ethanol-Induced Inflammatory and Fibrotic changes in Liver despite continued Ethanol Administration

We investigated the potential of arginine to reverse pathological changes in alcohol-induced liver injury. Four groups (six rats/group) of male Wistar rats were fed a fish oil-ethanol diet for 6 (group 2) or 8 (group 1) weeks. Rats in group 3 were fed fish oil-ethanol for 6 weeks, after which they were administered arginine with fish oil-ethanol for an additional 2 weeks. Rats in group 4 were fed fish oil-dextrose for 8 weeks. Liver samples were analyzed for histopathology, lipid peroxidation, cytochrome P4502E1 activity, nuclear factor-κB, and levels of messenger RNA for tumor necrosis factor-α, cyclooxygenase-2, and inducible nitric oxide synthase. Concentrations of endotoxin were measured in plasma. The most severe inflammation and fibrosis was detected in groups 1 and 2, as were the highest levels of endotoxin, lipid peroxidation, cytochrome P450 2E1 activity, activation of nuclear factor-κB, and mRNA levels for tumor necrosis factor-α, cyclooxygenase-2, and inducible nitric oxide synthase. Plasma nitric oxide was also increased as was nitrotyrosine in liver. After arginine was administered, there was marked improvement in the pathological changes accompanied by decreased levels of endotoxin, lipid peroxidation, activation of nuclear factor-κB, tumor necrosis factor-α, cyclooxygenase-2, inducible nitric oxide, and nitrotyrosine staining. The therapeutic effects of arginine are probably secondary to increased levels of nitric oxide but other effects of arginine cannot be excluded

Two cultures, one identity: formulations of Australian Isma'ili Muslim identity

The Shi'a Imami Nizari Isma'ili Muslims have often been considered the "poster child" for pluralistic integration (Cayo 2008). This ethos has been inculcated within members of the community, with its adherents seeing themselves as a diverse and multi-ethnic collective. Nevertheless, despite this purported pluralism, social research on the Isma'ilis has primarily focused on the diasporic and post-diasporic migrant communities of South Asian descent, the 'first and second-generation immigrants,' in the Euro-American context (Mukadam and Mawani 2006, 2009; Nanji 1983, 1986). The experiences of co-religionists in other contexts have often been neglected. This study examines how members of the self-described geographically and socially isolated Isma'ili community in Australia construct their identity vis-à-vis the larger, global, Isma'ili community, and how they have responded to the potential of identity threat given the arrival of another group of Isma’ilis with a differing migratory history integrating into the extant community. Using the approach of identity process theory, this study examines how salient features of identity are constructed amongst the Australian Isma'ilis, how religion and identity take on multiple meanings within the Australian Isma'ili context, and, finally, sheds light on the self-sufficiency of this community despite geographic and social isolation

New leadership model for family physicians in the Eastern Mediterranean region: a pilot study across selected countries

Background: Family Medicine is growing rapidly across the Eastern Mediterranean Region. However, it needs support in terms of overall health system development. This will require strong leadership in family medicine to implement the change required to improve current conditions. Objective: To collect data that will support the development of a leadership program for the future family physicians in the region. Methods: A cross-sectional study was conducted from July 2016 to September 2016 in eight countries of the Eastern Mediterranean Region, (Bahrain, Egypt, Iraq, Jordan, Kuwait, Qatar, Pakistan, and Saudi Arabia). These countries were selected to obtain perceptions of Family Physicians (FPs) regarding the current leadership model and to explore the need for a new future innovative model in Family Medicine (FM) across the region. Results: The information of 68 family physicians was included in the final analysis. The majority of the FPs was females as compared to males (71% vs. 29%). Forty-four percent of the FPs had 10 to 19 years of experience. Almost all of the FPs (96%) had completed some training in family medicine after graduation. About three fifths of the FPs had completed postgraduate qualifications and out of those, 64% had passed Board or Membership Examinations. Twenty-one percent of them are currently in a leadership role and 45% who were not in any leadership role responded that the current situation of FM in their country is poor. All of the leaders believed that it is important to develop strong leadership in FM to take the specialty forward. Almost similar proportions (67% and 64%) of leaders and non-leaders thought that establishing regional associations would enhance the FM practice model. Approximately two thirds of leaders (67%) responded that the current role of decision makers in the Ministry of Health (MOH) regarding capacity building in FM is not effective. The majority of the FPs (54% and 38%) considers that the existing postgraduate curriculum does not address leadership skill development in FM. Eighty-eight percent of the FPs both from leadership and non-leadership groups agreed that academic institutions and practicing FPs can play an effective leadership role in taking FM forward. Conclusion: The Family Medicine specialty will have to develop leadership capabilities in line with today’s fast-moving changes in healthcare for it to obtain the due recognition in the healthcare delivery system
