Journal of Cancer Therapy (JCT) , 2019, DOI: 10.4236/jct.2019.101008
Abstract: Aim: Globally, primary adenocarcinoma (AC) accounts for only 0.5% - 2% of bladder cancer (BC). Bilharziasis predisposes to AC in ~10% of BC in endemic regions. The aim was to study the clinicopathologic characteristics of this rare entity and define prognostic elements influencing disease-free (DFS) & overall survival (OS). Patients & Methods: A retrospective analysis of 42 cases of primary bladder AC presented to the National Cancer Institute of Egypt (NCI-E) during a five-year period (2010-2014), clinicopathologic profiles, management and survival were assessed. Results: The mean age was 55.5 years ± 9.77 with male predominance. Hematuria, bilharziasis & urachal type experienced in 88%, 35.7% & 4.8%, respectively. Radical surgery was employed in 64.3%. Metastatic disease (stageIVB) found in 14.3%,
Enforcement of Food Legislation and Its Impact on Food Safety: A Case Study on Food Law Enactment in Mauritius  [PDF]
Said Ajlouni, Yousof Gaungoo
Advances in Microbiology (AiM) , 2018, DOI: 10.4236/aim.2018.82008
Abstract: Foodborne diseases affect human health and cause significant economic loss. Among the proposed mitigating strategies to prevent, or at least, to reduce foodborne diseases were the enactment and proper enforcement of food legislation. In Mauritius (MU), many outbreaks have been reported since the enactment and enforcement of the Food Act 1998 (MU) and Food Regulations 1999 (MU). Therefore, it was high time to re-evaluate the impact of the food law on the pattern of foodborne diseases. The aim of this study was to evaluate how the introduction of the Mauritian food legislation had influenced the pattern of foodborne diseases and its suitability in recent years. Data were collected from the website of the Ministry of Health and Quality of Life of Mauritius from 1990 to 2015 and analysed using nonparametric statistical methods, where required. Results showed that more foodborne disease cases occurred during enforcement of the food legislation than before. The study also found that the food law was consistently enforced over the years, except during epidemics of chikungunya fever and dengue fever. Furthermore, several strengths and weaknesses were identified in the current legislation related to the risk of foodborne diseases. Comparing the Mauritian with the Australian food laws revealed some similarities and differences between the two legislations. This review showed that overall foodborne diseases in Mauritius increased and were not affected by the food law enforcement. Therefore, a revision of the law and its enforcement is necessary to make them more efficient in preventing foodborne diseases.
A Simplified Procedure for Prediction of Ultimate Strength of Beam-Column Channel Sections  [PDF]
Osama Bedair
Engineering (ENG) , 2011, DOI: 10.4236/eng.2011.310120
Abstract: A design procedure is presented to estimate the load carrying capacity of beam-column channel sections. A reduced cross-section is used to compensate for the reduction in the post-buckling stiffness. The non-linear stress distribution acting on the entire channel width is replaced by simplified linear distributions. Using this simplified concept, the maximum stress in the post-buckling state, is assumed to be carried entirely by both edges while the central region of the channel remains unstressed. Thus a fraction of the channel section is considered in resisting the applied loading. This approximation enables the structural engineer to deal with a simplified stress distribution to compute the ultimate strength instead of the non-linear one.

Abstract: Background: Intertrochanteric fractures are of intense interest globally. They are the most frequently operated fracture type, have the highest postoperative fatality rate of surgically treated fractures, and have become a serious health resource issue due to the high cost of care required after injury. A number of problems exist when determining the best option for treatment for intertrochanteric fractures. The classification systems do not work well enough for preoperative planning and the reduction criteria have not been well defined. Methods: All patients who presented to Firoozgar Hospital, Tehran with intertrochanteric fracture, between March 20th 2013 and December 21st 2015, underwent DHS implementation, after 6-month follow-up period. Demographic data, preoperative radiographic fracture, bone quality typing (AO/OTA and Dorr classification), American Society of Anesthesiologists (ASA) score and evaluation of their correlation with the complication of fixation including nonunion and device failure were recorded and analyzed. Result: 101 patients including 54 males (53.5%) and 47 females (46.5%) underwent DHS implementation. Mean population age was 73.06 ± 16.36 years with an age range of 30 to 94 years; the most frequent age period was 76 - 85 years, injured by low-energy trauma mechanism and 23.8% patients were injured in a high-energy trauma. 56 patients completed the 6-month follow-up evaluation which ranged from 1 to 80 weeks. According to AO/OTA classification, the most common type among the patient population was A2, 27 patients (51.5%); while the most common group from Dorr classification turned to be group B (39.6%). Classification by ASA score revealed Class II to be most frequent among the patient population (56.4%). Nonunion was seen in eight of patients (14.3%). Three patients (5.4%) had device failure, two cases showed side plate breakage, and another one had screw cut out. There was no significant relationship between AO/OTA classification with the both complications i.e. the development of device failure (P = 0.85) and nonunion (P = 0.99). Non-significant correlation was found between Dorr classification with device failure (P = 0.06) and nonunion (P = 0.11). Conclusion: Regarding recent studies, more effective factor on the outcome is patient’s medical condition before surgery compared to the radiographic findings including AO/OTA and Dorr classification.

Abstract: From the earliest times, traditional theatre in Southeast Asia has been shaped by a wide range of religious and cultural influences—those deriving from animism, Hinduism, Buddhism, Islam, as well as from Chinese and western traditions. The overwhelming influences, especially of Hinduism, have had the tendency to obscure contributions from the Middle- and Near-East. The view that Islam, with rare exceptions, prohibits performing arts has resulted in a negligence of these arts forms in Muslim societies with the possible exception of Indonesia. This paper highlights significant elements of Islamic culture that have shaped Indonesian and Malay traditional theatre through the adaptation of borrowed genres such as taziya, as well as locally created styles of shadow play (wayang kulit) and the doll-puppet theatre (wayang golek); the use of important themes from Islamic literature, in particular thosederived from Hikayat Amir Hamza; as well as esoteric interpretationsof certain episodes originally derived from pre-Islamic sources,including the Mahabharata, in terms of Sufism to make them both highly meaningful and acceptable to Muslim audiences.

Zahedan Journal of Research in Medical Sciences , 2010,
Abstract: Background: Diabetes mellitus is a metabolic disorder as old as mankind and its incidence is considered to be high all over the world. Oxidative stress is strongly associated with development and the complications of diabetes. Antioxidant agents, especially with the origin of plants, are of more importance in the treatment of diabetic complications. The main objective of the present study was to evaluate the effect of extract of the grape seed on antioxidants status in streptozotocin induced diabetic rats.Material and methods: In this laboratory experimental study which conducted in Islamic Azad University of Tabriz research center. Forty male Wistar rats were randomly assigned into four equal groups including healthy control group, healthy group treated with grape seed extract (40 mg/kg), diabetic control group and diabetic group treated with grape seed extract (40 mg/kg). The experimental rats were treated in related groups for 12 weeks and at the end of experiment serum level of malonaldehyde (MDA) and anti-oxidant enzymes activity including superoxide dismutase (SOD), glutathione peroxidase (GPx) and catalase (CAT) were measured in red blood cells. Statistically, comparison of the groups was carried out using one-way analysis of variance followed by Bonferroni post-hoc test. Differences were considered statistically significant at p< 0.05. Results: Diabetic rats showed significant increase in the value of MDA and a decrease in the activities of SOD, GPx and CAT of red blood cells (p<0.001). Oral administration of grape seed extract resulted in significant reduction in the level of MDA and significant increase in the activities of SOD, GPx and CAT of red blood cells (p<0.001). Conclusion: The results of this study provide confirmatory evidence of oxidative stress in diabetes and show the anti-oxidative effect of grape seed extract
Sequential quantum cloning under real-life conditions

Physics , 2012, DOI: 10.1103/PhysRevA.85.052323
Abstract: We consider a sequential implementation of the optimal quantum cloning machine of Gisin and Massar and propose optimization protocols for experimental realization of such a quantum cloner subject to the real-life restrictions. We demonstrate how exploiting the matrix-product state (MPS) formalism and the ensuing variational optimization techniques reveals the intriguing algebraic structure of the Gisin-Massar output of the cloning procedure and brings about significant improvements to the optimality of the sequential cloning prescription of Delgado et al [Phys. Rev. Lett. 98, 150502 (2007)]. Our numerical results show that the orthodox paradigm of optimal quantum cloning can in practice be realized in a much more economical manner by utilizing a considerably lesser amount of informational and numerical resources than hitherto estimated. Instead of the previously predicted linear scaling of the required ancilla dimension D with the number of qubits n, our recipe allows a realization of such a sequential cloning setup with an experimentally manageable ancilla of dimension at most D=3 up to n=15 qubits. We also address satisfactorily the possibility of providing an optimal range of sequential ancilla-qubit interactions for optimal cloning of arbitrary states under realistic experimental circumstances when only a restricted class of such bipartite interactions can be engineered in practice.
Efficient classical simulation of the Gisin-Massar quantum cloning machine

Physics , 2013,
Abstract: We provide here the technical details of the recently proposed tensor-network protocol for classical simulation of the Gisin-Massar quantum cloner by the authors [Phys. Rev. A, 85, 052323 (2012)]. The protocol essentially instructs how to efficiently simulate an optimal quantum cloning machine of Gisin-Massar on a classical computer. A viable computational platform for generation on demand of arbitrary number of optimal clones with controllable numerical resources is realized by rephrasing the Gisin-Massar output state in terms of the hierarchy of the so-called matrix-product states (MPS) and invoking parity features peculiar to such an output.

Abstract: Objective: To evaluate the association between type 2 diabetes mellitus and the reduction of mandibular residual ridge in completely edentulous patients wearing complete dentures and to investigate the ef-fect of gender, age and years of edentulousness / den-ture wearing on ridge resorption on both groups. Methods: Seventy-two (36 men and 36 women) with a mean age 63.5 years (range of 52 to 73 years) com-pletely edentulous denture-wearing patients were included in this study. Of these, there were 40 patients with type 2 diabetes mellitus and 32 control subjects participated in the study. Resorption in the mandibular residual ridges was assessed by using the mental foramen and the inferior border of the mandible, as they appear in panoramic radiographs, as reference points using Wical and Swoope Analysis method. Measurements were performed using “Dijite” Digital Caliper. The amount of mandibular ridge resorption was calculated and correlated with type 2 diabetes mellitus and the results were compared with control group. Differences in gender, age and years of edentulousness were investigated. Statistical analysis was performed using SPSS (V11.0). A 2-sample t-test was used to evaluate the differences in mean values of mandibular ridge resorption between diabetics and controls. Level of significance was set at 0.05. Results: The mean mandibular residual ridge resorption of all participants is 8.0 mm (26.9%), diabetic group significantly (P < 0.01) had two times more resorption compared with control group (35.8% versus 18.0%). Females recorded greater amount of resorption in diabetics 49.7% versus 21.8% (P < 0.001) and in controls 22.3% versus 13.7%, (P < 0.05) compared to males, respectively. There were no differences in both groups regarding the age of subjects and the length of time they have been edentulous and years of denture wearing. The amount of mandibular residual ridge resorption was directly related to the number of years of edentulousness. Conclusion: Completely edentulous, denture-wearing diabetics, women in particular, are at more risk to have ridge resorption than “nondiabetic” subjects. Reduced mandibular height is directly related to years of edentulousness and denture wear-ing with greater amount of resorption among diabet-ics.
