Surgical Science (SS) , 2015, DOI: 10.4236/ss.2015.63021

Situs inversus, a very rare congenital anomaly of reversal site of thoracic and abdominal organs, can be very problematic to surgeon while dealing with a case of trauma in emergency. Surgical procedures are considered difficult, complex and more challenging in patients with this condition due to the anatomical difference and position of organs. We came across an interesting and very rare case of isolated blunt traumatic diaphragmatic injury in a case of situs inversus. Traumatic injuries of the diaphragm are uncommon and isolated blunt traumatic injuries of diaphragm are very rare. Our case is very unique of its kind of situs inversus with isolated right sided diaphragmatic rupture in a 60-year-old male patient presenting 4 hours after blunt trauma to chest and abdomen.

Surgical Science (SS) , 2015, DOI: 10.4236/ss.2015.63024

Background: Gallstones are generally uncommon in infants and children. Formation of gallstone is a very poorly understood phenomenon. In general, the risk factors for cholithiasis in infants include patients who are ill, are receiving hyperalimentation, are premature, have congenital anomalies and have necrotizing enterocolitis. Children aged 1 - 5 years most frequently have hemolysis as the underlying condition [1]. Materials and Methods: From Jan 2012 to Feb 2014, a study entitled “A Prospective Study of Cholelithiasis in Children” was conducted in Postgraduate Department of General Surgery Govt. Medical College Srinagar. The patients selected for the study were in the age group of 1 to 14 years of either sex. There were a total of 141 cases, out of which only 38 had ultrasound documented gallstones. All the patients included in the study were evaluated for prevalence, clinical presentation, and pathological features of gallstones, and were analysed for metabolic causes of gallstones. Results: The prevalence of chliothiasis in symptomatic patients was found to be 26.95% higher than the prevalence of gallstones in children in other parts of world, also the mean age of presentation was 9.3 years ranging from 6 - 14 years. Male to female ratio was 3:2 and male predominance was found in all age groups contrary to female predominance in adults. Most common presenting symptom was right upper quadrant pain followed by vomiting and nausea similar to presentation of symptomatic gallstones in adults. 4 patients had a positive family history of cholithiasis in the first degree relatives; 25 (65.7%) patients had no underlying risk factor for gallstones contrary to presumption that gallstones in children are mostly secondary to some hematological disorder or other predisposing factors. Chronic cholecystities was found in 81% of patients with gallstones and composition of gallstones retrieved was different from those of adult gallstones with calcium carbonate gallstones relatively common in children but composition of black and brown stones was almost similar to adult stones. Conclusion: Gallstone disease was increasingly gaining recognition in peadiatic practice due to significant documented increase in non-heamolytic cases

Alfar Nafae, Raiees Ahmad, Amber Aliya, Yawar Nisar, Pervaze Salam, Imtiyaz Ahmad
Surgical Science (SS) , 2016, DOI: 10.4236/ss.2016.71002
Abstract: Background: Carcinoma stomach remains a major malignancy and accounts for 10.4% of cancer related deaths globally. Despite improvement in chemo-radiotherapy, surgery remains the primary curative modality with special emphasis on lymphadenectomy. However the extent of lymphadenectomy performed by surgeons all over the world differs. Generally speaking, in Japan and Korea, the standard curative protocol would entail a “D2” lymphadenectomy whereas in the western world it would be considered unnecessary and the standard protocol would entail a standard “D1” lymphadenectomy. Thus prompting a newer surgical therapy of modified D2 in dissection in which pancreas and spleen are preserved. Lymph nodes surrounding stomach are divided into 20 stations and these are classified into three groups depending upon the location of the primary tumour. Aims & Objectives: The aims and objectives are to compare: 1) operative time of modified D2 gastrectomy with that of D1 gastrectomy; 2) operative morbidity and mortality of modified D2 gastrectomy with that of D1 gastrectomy; 3) the disease recurrence between modified D2 & D1 gastrectomy. Materials & Method: The study entitled D1 versus modified D2 gastrectomy for Ca stomach—a prospective, comparative study was conducted in the Postgraduate Department of General Surgery, Government Medical College, Srinagar as a prospective, comparative study over a period of three years 2012-2014. Patients with resectable gastric cancer were taken as subjects for the study and were divided in 2 groups that were closely matched to avoid any bias. Assessment of both the groups was done in identical fashion as per standard protocol. One group underwent gastrectomy with D1 lymph node dissection whereas the other group underwent gastrectomy with a modified D2 lymph node dissection (spleen and pancreas preservation). The type of lymphadenectomy was decided on randomization (simple random sampling). Results: After comparing the two procedures, it was noted that: 1) modified D2 lymphadenectomy took on an average 2 hours more than D1 gastrectomy; 2) operative mortality was same in both the procedures. Operative morbidity was seen more in modified D2 group than D1 group however this difference was statistically insignificant; 3) number of recurrence was quite significant in D1 group but no recurrence was seen in modified D2 group. Conclusion: On the basis of the study, we recommend that modified D2 gastrectomy is a better procedure than D1

Abstract: This study explored the African American college students’ retention behavior and identifies the effect of different social, psychological and other factors. Randomly selected students from predominant African American university completed the perceived stress scale, self-motivation scale, parental involvement, childhood economic situation, mentorship and drug and alcohol use questionnaire. Non-parametric analyses suggested that higher stress level, childhood poverty, lack of parental involvement or support, without a mentor support and lack of self-motivation increase the likelihood of dropping out from college. This study’s findings have important implications for college retention among African American students.
Assessment of Surfactant Modified Activated Carbon for Improving Water Quality  [PDF]

Journal of Encapsulation and Adsorption Sciences (JEAS) , 2019, DOI: 10.4236/jeas.2019.91002
Abstract: Effluents containing inorganic contaminants are releasing into the environment untreated despite being hazardous to man and environment. It is costly and unsustainable to use conventional methods to remove them from dilute aqueous solution. Adsorption involving granular activated carbon is an alternative method for treating such effluents. Granular activated carbon is structurally strong, highly resistance to attrition and wearing, large and can easily separate from the effluents. However, its surface is highly hydrophobic and has little surface charge thereby reducing its adsorption capacity for anion or cation. This article reviews surfactant modification of activated carbon to enhance its adsorption capacity for inorganic contaminants and key factors affecting the adsorption efficiency. They include initial concentration of contaminants, contact time, solution pH, solution temperature, adsorbent concentration, ionic strength, competing ions, type of surfactant, and surfactant concentration. The modified activated carbon usually shows maximum contaminant uptake around its critical micelles concentration. Surfactant modification reduces specific surface area and/or micro pore volume but hot NaOH or HNO3 treatment before surfactant modification minimises this drawbacks and increases the net surface charge. Overall, surfactant modification is a simple but efficient method of enhancing adsorption capacity of activated carbon for removing anion or cation from aqueous solution. However, a handful publication is available on the regeneration of the spent (saturated) surfactant modified activated carbons. Hence, more research efforts should be directed towards proper regenerating reagents and the optimise conditions such as contact time, concentration, and temperature for regenerating spent modified activated carbons.

Objectives: Diabetic nephropathy is the leading cause of chronic kidney disease. The pathogenesis of DN remains incompletely understood. It has been recently demonstrated that inflammatory processes play a significant role in the development and progression of DN. Toll-like receptors play a fundamental role in the innate immune system by triggering proinflammatory signaling pathways. Our aim is to evaluate the expression of TLRs on monocytes and relate their expression with inflammation in HD patients with & without diabetic nephropathy. Method: In a case control study (60) patients from Alkasr El Aini Hospital on hemodialysis were divided into two groups: Group 1, 30 patients on heamodialysis not due to diabetic nephropathy, Group 2, 30 patients on heamodialysis due to diabetic nephropathy, compared to Group 3, including 30 healthy controls. All participants were subjected to: Full medical history, complete physical examination, Serum creatinine, uric acid, A1C, fundus examination, detection of TLR2, TLR expression by real time PCR in peripheral blood mononuclear cells. Data were statically calculated using SPSS, comparision between groups was done using student T test comparing 2 groups, correlation using spearman’s correlation. Results: Diabetic had significantly increased TLR2, TLR4 mRNA in peripheral blood mononuclear cells compared to controls and non diabetics patient on heamodialysis (p < 0.001), TLR2, TLR4 significantly correlated with dialysis duration in diabetic (p < 0.001), no correlation with A1C in relation to TLR2 (p = 0.078), TLR4 (p = 0.163). Conclusion: TLR2, TLR4 were significantly elevated in diabetic on dialysis initiating event in the pathogenesis of DN, providing a link between hyperglycemia and hypoxia with inflammation and fibrosis within the kidney. Hence, therapeutic interventions aimed at targeting the inflammatory component through interruption of TLR signaling may be a novel strategy to target prevention and treatment of DN.

Ahmed Ibrahim, Abdel Salam Hamdy
Journal of Surface Engineered Materials and Advanced Technology (JSEMAT) , 2011, DOI: 10.4236/jsemat.2011.13015
Abstract: Air Plasma spray process was used to deposit a conventional and nanostructured Al2O3-13 wt% TiO2 coatings on a stainless steel substrates. Morphology of the powder particles, microstructure and phase composition of the coatings were characterized by XRD and SEM. Potentiodynamic polarization tests and Electrochemical Impedance Spectro- scopy (EIS) were used to analyze the corrosion of the coated substrate in 3.5% NaCl solutions to determine the opti-mum conditions for corrosion protection. The fatigue strength and hardness of the coatings were investigated. The experimental data indicated that the nanostructured coated samples exhibited higher hardness and fatigue strength compared to the conventional coated samples. On the other hand, the conventional coatings showed a better localized corrosion resistance than the nanostructured coatings.

Abstract: Background: Primary hyperhidrosis of the upper limbs is characterized by over activity of the eccrine sweat glands, primarily occurring on palmar, plantar and axillary regions. It is distressing and often socially disabling condition. Conservative treatment is usually not effective in controlling the disease mainly due to adverse effect of therapies. Endoscopic thoracic sympathectomy is considered as the treatment of choice, causing minimal morbidity and high success rates and patient satisfaction. Objective: The study aims to evaluate the long-term outcomes of single port bilateralthoracoscopic dorsal sympathectomyin treatment of primary hyperhidrosis of the palm and axilla. Methods: In this prospective study, performed primarily by a single surgeon, between August 1st 2010, and August 1st 2012, we performed 200 thoracoscopies on 100 patients with signs and symptoms of primary palmar and axillary hyperhidrosis in different age groups and in both genders, and all were studied and analyzed following treatment by single-port bilateral thoracoscopic dorsal sympathectomy in Sulaimani teaching hospital. Results: Total of 99 patients were satisfied with the outcome of post-surgery with a follow-up in the mean of 27 months and only one patient was reported no change in symptoms postoperatively. Complications reported in 6 patients inform of compensatory sweating (n = 2), Gestatory sweating (n = 1), Pneumothorax (n = 1), Intraoperative minor bleeding (n = 1) and only 1% failure rate was reported. No mortality was reported. Conclusions: Single port bilateral thoracoscopic thoracic sympathectomy is a very effective method in the management of primary hyperhidrosis. Single port provides less postoperative pain, safety, short operative time, and quick method for the treatment of primary hyperhidrosis in comparison to two or three ports approaches.
Application of the Improved Kudryashov Method to Solve the Fractional Nonlinear Partial Differential Equations  [PDF]
Md. Abdus Salam, Umme Habiba
Journal of Applied Mathematics and Physics (JAMP) , 2019, DOI: 10.4236/jamp.2019.74061
Abstract: Our purpose of this paper is to apply the improved Kudryashov method for solving various types of nonlinear fractional partial differential equations. As an application, the time-space fractional Korteweg-de Vries-Burger (KdV-Burger) equation is solved using this method and we get some new travelling wave solutions. To acquire our purpose a complex transformation has been also used to reduce nonlinear fractional partial differential equations to nonlinear ordinary differential equations of integer order, in the sense of the Jumarie’s modified Riemann-Liouville derivative. Afterwards, the improved Kudryashov method is implemented and we get our required reliable solutions where the results are justified by mathematical software Maple-13.
STUDENTS‘ FIRST IMPRESSION OF SECOND LIFE: A case from the United Arab Emirates
The Turkish Online Journal of Distance Education , 2011,
Abstract: Emerging 3D virtual worlds such as Second Life can offer students with opportunities to enhance learning using rich collaborative asynchronous media. Virtual worlds are believed to impact the future of higher education and therefore, universities across the world are immersing themselves inside virtual worlds to establish a unique learning and research environments. This research examines the viability of Second Life as an educational platform from the perspective of a group of students in an Islamic society context. The students were attending one of the universities in the United Arab Emirates. The analysis indicates that students experienced both positive and negative aspects of Second Life. The results do encourage further experimentation in this positive novel way for learning.
