Is There Any Difference in the Plasma Homocysteine Levels of Diabetes Mellitus Type Ii Patients, Impaired Glucose Tolerance Subjects and Normal People?
M Mohammadi,A Amin-Alroaaya,H Rezvanian,A Kachoie
Journal of Shahid Sadoughi University of Medical Sciences , 2005,
Abstract: Introduction: Hyperhomocysteinemia is associated with an increased risk of cardiovascular disease in diabetic patients. The aim of this study was to determine plasma homocysteine levels in diabetics and compare with control persons and also evaluation of correlation between plasma homocysteine concentration and diabetic related variables. Methods: This study was done on 39 type II diabetic patients, 27 subjects with impaired glucose tolerance and 23 normal persons referring to Endocrine and Metabolism Research Center of Medical university of Isfahan. Physical characteristics were recorded. After an overnight fast, a blood sample was drawn for determination of FPG, HbA1c – homocysteine, Cr. Cholesterol – Triglyceride and HDL- Cholesterol. Mean plasma homocysteine levels in the groups were compared by one way ANOVA. The Correlation of different parameters was tested by Pearson’s correlation. Results: There was no statistically significant difference in the plasma homocysteine levels of all the groups.(P=0.71). Correlation between homocysteine levels and HbA1c was not significant (P=0.42) in diabetic patients. Conclusions: The findings suggest that diabetes does not influence plasma homocysteine levels.Also, there is no correlation between plasma homocysteine levels and HbA1c in diabetic patients

Abstract: al anticoagulation to reduce risk of stroke in patients with atrial fibrillation: current and future therapies Review (1488) Total Article Views Authors: Amin A Published Date January 2013 Volume 2013:8 Pages 75 - 84 DOI: http://dx.doi.org/10.2147/CIA.S37818 Received: 06 September 2012 Accepted: 29 November 2012 Published: 22 January 2013 Alpesh Amin Hospitalist Program, University of California, Irvine, Orange, CA, USA Abstract: Atrial fibrillation (AF) is associated with an increased incidence and severity of strokes. The burden of AF-related stroke is expected to increase in parallel with the aging of the population. Oral anticoagulation with warfarin has been the pharmacologic standard for stroke risk reduction in patients with AF. When used with close attention to dosing and monitoring, warfarin is effective prophylactic therapy against thromboembolic stroke. However, it is underused by physicians, in part because of the known risks of adverse events with warfarin. Consequently, many patients with AF live with an avoidably elevated risk of stroke. New options, ie, oral anticoagulants with novel mechanisms of action, have recently been approved to reduce the risk of stroke in AF, and others are in development. These newer agents may address some of the complexities of warfarin use while providing similar or better efficacy and safety.

Topical negative pressure in managing severe peritonitis: A positive contribution?
Amin Ibrahim Amin, Irshad A Shaikh
World Journal of Gastroenterology , 2009,
Abstract: AIM: To assess the use of topical negative pressure (TNP) in the management of severe peritonitis.METHODS: This is a four-year prospective analysis from January 2005 to December 2008 of 20 patients requiring TNP following laparotomy for severe peritonitis.RESULTS: There were 11 males with an average age of (59.3 ± 3.95) years. Nine had a perforated viscus, five had anastomotic leaks, three had iatrogenic bowel injury, and a further three had severe pelvic inflammatory disease. TNP and the VAC Abdominal Dressing System were initially used. These were changed every two to three days. Abdominal closure was achieved in 15/20 patients within 4.53 ± 1.64 d. One patient required relaparotomy due to residual sepsis. Two patients with severe faecal peritonitis due to perforated diverticular disease received primary anastomosis at second look laparotomy, as sepsis and their general condition improved. In the remaining 5/20 cases, the abdomen was left open due to bowel oedema and or abdominal wall oedema. Dressing was switched to TNP and VAC GranuFoam . Three of the five patients returned a few months later for abdominal wall reconstruction and restoration of intestinal continuity. Two patients developed intestinal fistulae. All 20 patients survived.CONCLUSION: The use of TNP is safe. Further studies are needed to assess its value in managing these difficult cases.

These procedures strongly activate the clotting cascade and increase the risk of venous thromboembolism (VTE). While everyone can agree that VTE is a serious and preventable problem following orthopedic surgery, not everyone agrees on best practice guidelines. This is compounded by the fact that there are multiple methods of VTE prevention including various chemoprophylactic and mechanical options as well as multiple organizations that have developed sometimes conflicting guidelines for VTE prevention including the American College of Chest Physicians and the American Academy of Orthopedic Surgery. The purpose of this paper is to present the available research on prominent chemoprophylactic VTE options for orthopedic surgery, examine and compare leading VTE prevention guidelines, and discuss the ramifications for noncompliance with industry standard guidelines.

Inflaton fragmentation: Emergence of pseudo-stable inflaton lumps (oscillons) after inflation
Mustafa A. Amin
Physics , 2010,
Abstract: We investigate the emergence of large, localized, pseudo-stable configurations (oscillons) from inflaton fragmentation at the end of inflation. We predict the number density of large oscillons, and the conditions necessary for their emergence in a class of inflationary models. Analytic estimates are provided for a 3+1 and 1+1-dimensional universe. We test our predictions with detailed numerical simulations in 1+1-dimensions. We see a zoo of oscillons emerging from the simulations, including the usual small amplitude "sech" oscillons as well as large "flat-topped" oscillons. The emergent oscillons account for approximately 80 per cent of the energy density of the inflaton.
K-Oscillons: Oscillons with Non-Canonical Kinetic Terms
Mustafa A. Amin
Physics , 2013, DOI: 10.1103/PhysRevD.87.123505
Abstract: Oscillons are long-lived, localized, oscillatory scalar field configurations. In this work we derive a condition for the existence of small-amplitude oscillons (and provide solutions) in scalar field theories with non-canonical kinetic terms. While oscillons have been studied extensively in the canonical case, this is the first example of oscillons in scalar field theories with non-canonical kinetic terms. In particular, we demonstrate the existence of oscillons supported solely by the non-canonical kinetic terms, without any need for nonlinear terms in the potential. In the small-amplitude limit, we provide an explicit condition for their stability in d+1 dimensions against long-wavelength perturbations. We show that for d > 2, there exists a long-wavelength instability which can lead to radial collapse of small-amplitude oscillons.

Abstract: During operating of the X-ray machines, if the protection of X-ray rooms is insufficient, not only the patient but also clinical staffs as well as public are exposed to high X-ray dosage and they are affected from X-ray related to the dose level. In the present survey, by testing the radiological leakage and scatter from X-rays machines in radiology departments of 7 randomly selected hospitals in Duhok governorate, the effects dose of X-ray to the both control panel area and the patients waiting or visiting area who are located near the radiography room, were measured. The dose was recorded for a range of peak kilovoltage (kVp) and mAs values to find efficiency of shielding materials (barriers) of radiography rooms for different X-rays level. The measurements were performed at one meter above the ground surface which was the same height of X-rays tube by using Gamma Scout dosimeter. From the measurement results, it was seen that the most hospitals barriers (doors and walls) were not appropriate to the standards except 2 hospitals. The maximum effective doses were measured in uncontrolled area of Khazer hospital which was 82.48 ± 0.73 mSv·yr-1 that was much more than the reference dose limits and in controlled area of Haval Banda Zaroka hospital which was 12.98 ± 0.16 mSv·yr-1. In result, the knowledge about the radiation dose affecting the radiologists and public in the selected hospitals was obtained, and by informing the radiologists and the hospitals managements, the necessary regulations would be planned.
