Hana El Mansouri, Amal Zourair, Hanane Hammaoui, Salma Amouzoune, Ibtissam Zouita, Dounia Basraoui, Hanane Rais, Hicham Jalal
Open Access Library Journal (OALib Journal) , 2019, DOI: 10.4236/oalib.1105122
Abstract:
Desmoid tumors are invasive and aggressive deep fibromatosis rare in children. They occur in muscles, their sheaths and fasciae. Medical imaging (CT and MRI) can suggest the diagnosis, guide the therapeutic management and the follow-up. We report a pediatric case of desmoid tumor of the pelvis through which we describe the clinical and radiological appearance of these tumors in children.
Curious Vascular Tumor

Case Reports in Dermatological Medicine , 2012, DOI: 10.1155/2012/542594
Abstract: Introduction. Sinusoidal hemangioma is a rare variant of acquired cavernous hemangioma predominantly occurring in females. Very few case reports have been described in the literature. Case Report. We present a case of a 46-year-old woman who noticed a slowly growing, cutaneous nodule on the left breast. Local excision of the lesion was performed and histology allowed to find a sinusoidal hemangioma. No recurrence was noticed. Conclusion. The very few reports of such a lesion in the literature reflect either rarity of such lesions or unfamiliarity of this subset among the pathologists.

Case Report. We present a case of a 46-year-old woman who noticed a slowly growing, cutaneous nodule on the left breast. Local excision of the lesion was performed and histology allowed to find a sinusoidal hemangioma. No recurrence was noticed. Conclusion. The very few reports of such a lesion in the literature reflect either rarity of such lesions or unfamiliarity of this subset among the pathologists. 1. Introduction Sinusoidal hemangioma (SH) was first described by Calonje and Fletcher [1] in 1991. They described this acquired benign vascular lesion as a rare subset of cavernous hemangioma. The lesions, occurring mostly in females, were solitary, deep dermal, or subcutaneous lobular vascular nodules histologically composed of dilated intercommunicating vascular channels lined by a single layer of endothelial cells with occasional pseudopapillae formation. They may have many clinical aspects, and microscopically some cases can mimic well-differentiated angiosarcoma. Although SHs are very rare, their clinicopathological characteristics are important to be recognized in order to avoid diagnostic pitfalls. We are reporting such a case occurring in a 46-year-old woman and briefly reviewing the literature 2. Case Report A 46-year-old woman had a painless, slowly growing, cutaneous nodule on the left breast with a duration of 6 months. Clinical examination showed a nontender, firm, slightly raised 1?cm cutaneous nodule with purplish discoloration of the overlying skin (Figure 1). There was no other systemic disease. The patient underwent an excisional biopsy of the lesion. Gross examination showed a subcutaneous, well-demarcated, and lobulated mass measuring 1?cm. Cut surface was spongy, hemorrhagic, and firm. Microscopically, the tumor was well circumscribed, located in the deep dermis and the subcutaneous tissue (Figure 2), and was composed of multiple lobules of greatly dilated, thin walled ramifying and anastomosing vascular channels (Figure 3), demonstrating a characteristic sinusoidal appearance with area of pseudopapillary pattern (Figure 3). Closely packed intercommunicating cavernous vessels filled with blood and lined by a single layer of flattened endothelial cells were observed (Figure 4). There was no significant nuclear atypia or mitoses of the endothelial cells. Six months after excision, there was no sign of recurrence. Figure 1: Breast cutaneous nodule with
H(.,.)- φ - η - Accretive Operators and Generalized Variational-Like Inclusions  [PDF]

Abstract: In this paper, we generalize H(.,.) accretive operator introduced by Zou and Huang [1] and we call it H(.,.)- φ - η - accretive operator. We define the resolvent operator associated with H(.,.)- φ - η - accretive operator and prove its Lipschitz continuity. By using these concepts an iterative algorithm is suggested to solve a generalized variational-like inclusion problem. Some examples are given to justify the definition of H(.,.)- φ - η - accretive operator.
Identification of Artificial Recharge Sites in Manchi Basin, Eastern Rajasthan (India) Using Remote Sensing and GIS Techniques  [PDF]
Subah Rais, Akram Javed
Journal of Geographic Information System (JGIS) , 2014, DOI: 10.4236/jgis.2014.62017
Abstract:

The present study is an attempt to prepare a water resource development action plan for Manchi basin in Eastern Rajasthan (India) using remote sensing and GIS techniques. Satellite data have proven to be very useful for surface study, especially in the preparation of land use/land cover and geomorphological map. Morphometric parameters are analyzed to understand the basin characteristics and its influence on the water resources for instance bifurcation ratio indicates high surface run off and low recharge in SB-I, IV, V. Low drainage density ranges from 2.41 (SB-IV) to 2.99 (SB-V) km/km2, with an average of 2.72 km/km2 showing permeable strata, dense vegetation and low relief. Analysis of shape parameters i.e. elongation ratio and circularity ratio suggest that Manchi basin is elongated in shape. Whereas, slope, geology and geomorphological mapping is done to demarcate groundwater potential zones for future exploration in the study area. Slope is inversely proportional to infiltration. Therefore, sub-basin areas having gentle slope permits less runoff and more infiltration as in alluvial plains and vice versa where hills and ridges are present. The integrated study helps in designing suitable sites for constructing water harvesting structures. Check dams, percolation tanks and nala bund are proposed at 1st, 2nd or 3rd drainage orders at SB-I and SB-IV with ravenous land (open scrub), uncultivated land, open forest & exposed rock present. Nala bund & check dam are proposed at SB-II & SB-V whereas, at SB-III check dams & percolation tanks are proposed so as to conserve the natural resources present in the basin. Finally, the best feasible water harvesting structures have been proposed within the sub-basins area using remote sensing and GIS techniques.

Abstract: This article is to shed some light on the socio-cultural and linguistic profiles of Maghnia speech community and that this homogeneous society has a shared linguistic system and norms, although the use of language differs depending on certain social parameters including gender, age and the educational background. In other terms, Maghnia speakers share the same religious principles, language and history. Maghnia speech community in particular has been influenced by many social and political factors throughout its history. The main factor which makes this society different is its geographical location and contact with Morocco.
Elaboration and Characterization of AuCl Semiconductor Nanocrystals Embedded in KCL Single Crystals  [PDF]
Fouzia Zehani, Miloud Sebais, Hanane Zaioune
Journal of Modern Physics (JMP) , 2012, DOI: 10.4236/jmp.2012.37073
Abstract: In this work, we investigated the structural and the optical properties of AuCl semiconductor nanocrystals embedded in KCl single crystals. The AuCl nanocrystals were obtained by doping the KCl crystalline matrix with gold using the Czochralski method. The X-ray diffraction showed the formation of the AuCl nanocrystals in KCl with a tetragonal structure. The average radius of the AuCl nanocrystals is estimated using the Scherrer formula. The photoluminescence spectra presented a band emission situated at 580 nm leading to the formation of the AuCl nanocrystals within KCl.
Comparison of Alternative Strategies for Multilevel Optimization of Hierarchical Systems  [PDF]
Saber DorMohammadi, Masoud Rais-Rohani
Applied Mathematics (AM) , 2012, DOI: 10.4236/am.2012.330204
Abstract: The augmented Lagrangian penalty formulation and four different coordination strategies are used to examine the nu- merical behavior of Analytical Target Cascading (ATC) for multilevel optimization of hierarchical systems. The coordination strategies considered include augmented Lagrangian using the method of multipliers and alternating direction method of multipliers, diagonal quadratic approximation, and truncated diagonal quadratic approximation. Properties examined include computational cost and solution accuracy based on the selected values for the different parameters that appear in each formulation. The different strategies are implemented using two- and three-level decomposed example problems. While the results show the interaction between the selected ATC formulation and the values of associated parameters, they clearly highlight the impact they could have on both the solution accuracy and computational cost.

Abstract: Background: Purpose of our study was to find out correlation between estimated Glomerular Filtration Rate (GFR) by Modification of Diet in Renal Disease (MDRD) formula and Glomerular Filtration Rate by Cockcroft-Gault equations, in patients with chronic kidney disease (CKD), and to see whether they can be used interchangeably. Methods: We conducted a cross section study of 70 patients presented to the nephrology clinic over a period of one year. We compared the Glomerular Filtration Rate by these two formulas in five stages of Chronic Kidney Disease. Abbreviated 4 variable Modification of Diet in Renal Disease formula was used.Results: Age range was 15 - 79 years; Male 49%, Female 51%. The correlation (r) between eGFR by MDRD and eGFR by Cockcroft-Gault equation for CKD stages 1 to 5 was 0.64; 0.31; 0.32; 0.67; and 0.45 respectively. The correlation (r) between creatinine clearance by 24 hour urine collection and MDRD formula was 0.84 (P: 0.001). The correlation (r) between creatinine clearance by 24 hour urine collection Cockcroft-Gault equation was 0.79 (P: 0.001). Conclusion: We conclude that Cockcroft-Gault equation correlates best with MDRD formula at CKD stages 4 and one. Cockcroft-Gault equation underestimated eGFR in stages 1, 2 and 3 of chronic Kidney Disease.

Abstract:

The ill effects of green revolution include residues of extensively used chemical pesticides in various environmental components. The present study was designed to analyze the levels of organochlorine pesticide residues along with chemical composition in buffalo milk samples collected from different localities of Delhi. Milk monitoring can yield information about the kinds and quantities of pesticides in the environment as well as in our daily diet. In this study, the residue of three different organochlorine pesticides, namely Hexachlorocyclohexane (HCH), Dichlorodiphenyltrichloroethane (DDT) and Endosulfan have been reported. Residues of Lindane exceeded the Maximum Residual Limit values in 50% of the samples is a cause of serious concern. The p,p-DDT was detected in 70% of the samples with p,p’-DDE (dichlorodiphenyldichloroethylene) in 80% of the milk samples of different parts of Delhi state. DDD (Dichlorodiphenyldichloroethane) another metabolite of p,p’-DDT was detected in 65% of the milk samples. The analysis indicates that DDT is the major contaminants in different parts of Delhi state. α and β endosulfan were detected in 35% and 40% of the samples analyzed. The statistical correlation shows no significant correlation between chemical compositions of the samples. The presence of multiple chemicals in virtually all samples of buffalo milk raises new questions about the possible toxicological impacts of chemical mixtures on an infant’s developing nervous and immune systems and reproductive organs.
