Purselane oleracea leaves constituents in a group of nature antioxidant. In this study, the antioxidant extracts of whit methanol 80% and distils water done, and then purified extract, powders were dry. After wards the composition in both extractions by GC/MC detection. The antioxidant properties of the resulting powder in different concentrate utilize among two concentrate of - tocopherol (200 ppm and 500ppm) and BHT(100 ppm and 200ppm) in sunflower oil, Purselane leaves treatment with different concentration of aqueous extract and methanol extracting (0.025, 0.05 and 0.075%) at 50°c and 0,5, 10,15,20 days of indicates DPPH, phenolic compounds, peroxide value(p.v) and thiobarbituric acid (TBA) were evaluated and compared. The resulting of GC/MC showed that the major components of the aqueous extract and methanol extract including fatty acid (Palmitic acid, luric acid, behenic acid, ascorbic acid, palmetic acid, Linolenic acid, Linoleic acid) essential amino acid (Pyro glutamic acid and Glutamic acid), nature phenolic, aromatic ketone, antioxyne B and coumaran. Both extraction were also to reduce DPPH radical but the amount of phenolic components in the extraction were higher than the aqueous extract all concentration of extract of Purselane leaves peroxide value and TBHQ were able to reduce and oxidation rate of formation of hydro peroxide have reduce(p0.05). it should be noted that the quest extract of Purselane has strong antioxidant properties them extract methanol the above

Background: We tried to understand whether or not there are lowered prevalences of terminal consequences of sickle cell diseases (SCDs) with tonsilectomy.\nMethods: All cases with SCDs were taken into the study.\nResults: The study included 334 patients (164 females). There were 27 cases with tonsilectomy and 307 cases without. The mean ages, female ratios, and prevalences of associated thalassemia minors and smoking were similar in both groups (p>0.05 for all). Although the white blood cell and platelet counts of peripheric blood were higher in patients without tonsilectomy, the mean hematocrit value was lower in them, but the differences were nonsignificant probably due to the small sample size of the tonsilectomy group (p>0.05 for all). Similarly, although the painful crises per year, digital clubbing, leg ulcers, pulmonary hypertension, chronic obstructive pulmonary disease, rheumatic heart disease, avascular necrosis of bone, cirrhosis, stroke, and mortality were higher in cases without tonsilectomy, the differences were nonsignificant probably due to the same reason again (p>0.05 for all).\nConclusion: There may be an inverse relationship between prevalence of tonsilectomy and severity of SCDs, and the tonsils may act as chronic inflammatory foci accelerating the chronic endothelial damage all over the body in such patients.

The main goal of this work is to identify places with different environmental sensitivity to land degradation in Siwa Oasis (Egypt) by means of a modelling approach developed in the European Commission funded MEDALUS project (Mediterranean Desertification and Land Use) which identifies such areas on the basis of an index (Environmental Sensitive Area index, ESA index) in which environmental quality (climate, vegetation, soil) as well as, FAO/UNEP provisional methodology for the common degradation process, are integrated and mapped.\nSiwa Oasis is vulnerable to decertification due to its fragile ecosystem and intensive human activity. Studies reveal that desertification is both a natural and anthropogenic process. Three decertification indicators (vegetation, soil and climate indices) were used to assess the severity of decertification in the region with Geoinformation technology (Remote Sensing, Geographical Information System \'GIS\' and Global Positioning System \'GPS\'). The first two factors were derived from multitemporal remote sensing. The last factor was calculated from census data. The results indicated that the senetivity of the studied area are ranged from moderatelt sensitive to very severe sensitive area to degradation. Where, 48.9 % (149.52 km2) of the studied area are moderately sensitive area to degradation, while the very severe area to degradation are representing 37.56 % (102.61 km2). The rest of the study area 55.63 km2 (17.56%) are characterized by sever area to degradation. According to the FAO/UNEP methodology the most common process of land degradation are the salinity and wind erosion hazard. The slainty status of the study area shows amoderate to very severe condition except in small patches located in the eastern part of the study area, while the wind erosion status has a range form moderate to severe hazard ecept small patches has a slightwind erosion hazad located in theeastern and southern part of the oasis.

This paper is devoted to the problem of modeling of the firms\' behavior under various social and economic risks. Drawing on the theoretical concepts of the social space by Bourdieu and of the multiple orders of worth by Boltanski and Thévenot the author attempts to construct a space of the firms operate in the region, to structure this space and differentiate between main groups of companies depending on their risk perception and risk avoiding practices.

Healthcare industry is an importance area within the services sector. Sustainable Supply Chain Management (SSCM) in healthcare industry leads tremendous opportunities for healthcare managers to improve production and distribution operations in the country. This study reviews relationship an empirical study between SSCM and Kaizen Blitz (KB) in Malaysian healthcare industry. It also provides management insight about SSCM and sustainable performance. SSCM and KB are importance to the healthcare industry to maintain success and improved quality and sustainable performance. Likewise, good quality of professionals all segments of the healthcare resources to increase at, bottom line, organizational efficiencies, quality of care, and the patient safety and satisfaction. Structural Equation Modelling (SEM) has been suggested to a conceptual model of this research. According suggested conceptual model and reviewed, investigation hypothesis was developed. This paper is concluded of opportunities to work in the future research.

Objective of work: is to point out that the teeth with periodontal changes such as the presence of periodontal pockets, after proper periodontal treatment could be abutments of choice for fixed partial dentures.\n Materials and Methods: 60 subjects were divided into 3 groups, the first group were 20 patients with PIR - 4 (initial stage of periodontal disease and DPP-depth of periodontal pocket of 3 mm), and the second group were 20 patients with PIR -5 (clinically manifest stage of periodontal disease and DPP of 3-6 mm). Control group consisted of 20 subjects without clinical signs of periodontal disease and without undergone periodontal treatment.\nPariodontal changes are verified according to the modified index of Ramfjord for DPP divided in three stages: DPP of 3 mm, 3-6 mm and DPP over 6 mm. DDP was measured with special graduated probe \"Flexibile Plastic\" probe. As periods for measurement for DPP on abutments for fixed partial denture were chosen: before preparation of abutments, after 24h of preparation, 6 and 18 months from definitive cementing of fixed partial dentures.\n Results: indicated a positive progression of gingival health related to DPP after a period after 6 and 18 months.\nAfter 18 months, in participants from the first group, in 30 (75.00%) mesial and 30(75.00%) distal abutments, the average value for the depth of periodontal pockets was 3 mm, or PIR-4. In 10 (25.00%) mesial and 10 (25.00%) distal abutments,, we have identified DPP of 4 mm or PIR – 5., \n Conclusion: We can easily derive the conclusion that the teeth with damaged periodontal health and the presence of DPP should not be excluded from their use as abutments for fixed partial dentures.
