Culture-based analysis of ascitic fluid has shown that a wide range of bacterial species can be isolated. Despite this, even where the most modern practice is applied, ascites fluid culture is negative in approximately 20% of patients with clinical manifestations suggestive of SBP, including elevated ascites polymorphonuclear leukocyte (PMN) counts. Where there is evidence of infection, delaying treatment until the ascitic fluid culture grows bacteria may result in the death of the patient from overwhelming infection [3] .

This hierarchical architecture provides the integration of a large number of IPs in a single on-chip system. The network encoding and decoding schemes for CDMA transmission are provided. The proposed CDMA NoC architecture is compared to the conventional architecture in terms of latency, area and power dissipation. The overall area required to implement the proposed CDMA NoC design is reduced by 24.2%. The design decreases the latency of the network by 40%. The total power consumption required to achieve the proposed design is also decreased by 25%.

We studied variation in the mitochondrial 16S rRNA gene within 12 populations from different ecogeographical regions of Egypt. Our results indicate a high genetic variation among L. quinquestriatus populations with five haplotypes existing. Our data also suggests the existence of a distinct population of L. quinquestriatus in Sinai which may be a separate species.

Six ecologically distinct zoogeographical regions are targeted in a collection scheme. The ecological and historical biogeography of the present-day distribution of the scorpion fauna of Egypt is discussed.

Aim of Study: Validation of a noninvasive test called P2/MS and its comparison with other noninvasive tests for the detection of high risk esophageal varices. Patients and Methods: We prospectively enrolled 125 consecutive patients with liver cirrhosis. Complete blood count [CBC], Platelet count by direct method, Liver functions [serum bilirubin, AST, ALT, prothrombin time and concentration and serum albumin], kidney functions, hepatitis markers for B & C, abdominal ultrasonography and upper gastrointestinal endoscopy were done for each patient. Calculation of P2/MS [Platelet count) 2 /{monocyte fraction (%) × segmented neutrophil fraction (%)], API [age-platelet index], APRI [AST-to-platelet ratio index], SPRI [spleen-toplatelet ratio index], ASPRI [age-spleen-to-platelet ratio index] scores and correlating the different scores with the grade of esophageal varices found on upper endoscopy. Results: During processing of our patient's data, we found certain relation between segmented neutrophils, monocytes, platelet count, total bilirubin and the degree of esophageal varices for the detection of high risk varices and a new equation was formulated and we called it P2/MS-B. In predicting high risk esophageal varices HREV, the area under the curve for this new variable was [0.909, 95% confidence interval 0.858-0.961, p = 0.000] which was significantly higher than all the other variables including P2/MS for the detection of HREV. The sensitivity of the new equation for the detection of HREV is 85.3%, the specificity is 83.1%, the positive predictive value is 87.9%, the negative predicative value is 86.0 % and the overall accuracy of the test is 85.6%. Conclusion: A newly detected noninvasive variable for detecting HREV may reliably screen liver cirrhosis patients for HREV and avoid unnecessary endoscopy in low risk patients.

The aim of this study was to assess the role of faecal calprotectin in differentiating between both groups of patients in order avoid the use of invasive diagnostic procedures in patients with low probability of having functional disorders.
