Eid, A., "Cylindrical thin-shell wormholes supported by phantom energy", The European Physical Journal Plus, vol. 131, no. 9, pp. 298, 2016. AbstractWebsite

In the framework of Darmois-Israel formalism, the general equations describing the motion of cylindrical thin-shell wormholes supported by equation of state of phantom energy are derived. The linear perturbation approach is used to investigate the stability of a cylindrical thin-shell wormhole of a static solution.

Cyclospora cayetanensis (C. cayetanensis) can cause serious diarrheal illness in immunocompromised patients. The present work aimed to detect C. cayetanensis infection among patients with renal transplantation attending the nephrology unit of Kasr Al-Aini, Faculty of Medicine, Cairo
University. A total of 50 stool samples were collected and subjected to direct microscopy to screen
for parasitic stages. A modified acid fast staining technique (Kinyoun’s method) was used to detect
C. cayetanensis oocysts. Cyclospora oocysts were revealed in 5 (10%) of the stool samples examined. Other parasites detected among the patients included Cryptosporidium parvum 5 (10%) and
Blastocystis 15 (30%). 30% of the patients were suffering from diarrhea and or colic. All C. cayetanensis positive cases were presenting with diarrhea.

Abstract

Background and Aim: Type 2 diabetes mellitus (DM) is the most common single cause of the end-stage renal disease (ESRD). Cyclophilin A (CyPA) is an 18-kD protein. The connection between diabetic nephropathy (DN) and the secreted form of CyPA (sCyPA) has been elucidated in this study that aims to investigate sCyPA correlation with renal dysfunction.

Materials and Methods: Thirty-four male adult Wistar rats weighing 180-220 g were used. Animals were divided into a study group and a control group, 17 rats in each. Streptozotocin (STZ) and nicotine amide were used to damage some pancreatic cells for induction of type 2 DM. Comparison was made between the study and the control groups. Moreover, a comparison was made between the members of the study group before and after induction of DN.

Results: The rat model that exhibited a higher concentration of urinary sCyPA was detected early in the eighth week. There was a significantly higher level of 24-h urinary CyPA in the study group compared to the control group (-value=0.004) and there was a significant elevation in the 24-h urinary Cyp-A in the study group after injection of STZ compared to the values before injection (-value <0.001). Immunohistochemical analysis of renal tissue revealed that the mean expression of CyPA was higher in the study group than in the control group. For the urinary 24-h CYP-A, using a cutoff of 1.15 ng/mL, the accuracy was 72.4%, sensitivity was (77.8%) and specificity was (67%).

Conclusion: According to this animal study, we proved that CyPA is a valuable marker for DN. It is a more sensitive, noninvasive and rapid biomarker for early detection of any renal affection in human diabetic patients.

BACKGROUND: Cyclooxygenase-2 (COX-2) is an inducible modulator of inflammation that acts through increasing prostaglandin levels and has been described as a major mediator linking inflammation to cancer. Previous studies supported that COX-2-765G>C and -1195A>G polymorphisms were associated with increased risk of several solid tissue cancers as well as some hematological malignancies.

OBJECTIVE: The aim of the study was to elucidate the association between functional COX-2 genotypes (-765G>C and -1195A>G) polymorphisms and the risk of developing mycosis fungoides (MF).

METHODS: This was a hospital-based, case-control study of 70 MF patients and 100 MF-free controls. We genotyped COX-2 -1195A>G, -765G>C, and -8473T>C polymorphisms by using the PCR-restriction fragment length polymorphism method.

RESULTS: The AA genotype in the COX-2 -1195A>G gene polymorphism and the GC genotype in the COX-2 -765G>C gene were significantly more frequent among MF patients compared to controls (p< 0.001 and p = 0.002, respectively).

CONCLUSION: The -results indicate a possible role of COX-2 genes in the pathogenesis of MF. These novel findings may allow for notable future advances, as it will enable the identification of the -individuals most susceptible to MF.

Khairy, R., "Cyclooxygenase-2 and estrogen receptor-β as possible therapeutic targets in desmoid tumors", Kasr Al Ainy Medical Journal, vol. 24, issue 2, pp. 47 - 52, 2018/5/1. AbstractWebsite

Background and aim Desmoid tumors are mainly treated by surgical excision and radiotherapy, but the failure to achieve complete response has given rise to the need for investigating the role of possible target therapy. The aim of this study was to evaluate the immunohistochemical detection of cyclooxygenase-2 (COX-2) and estrogen receptor-β (ERβ) in desmoid tumors and to assess their correlation with available clinicopathologic variables.
Materials and methods A total of 17 desmoid tumor cases (11 abdominal, five extra-abdominal, and one intra-abdominal) were examined for immunohistochemical detection of COX-2 and ERβ using monoclonal antibodies. Toluidine blue staining was performed to confirm or exclude that COX-2 immunostained cells coincide with mast cells in co-localized sections. Correlation of results with available clinicopathologic variables was done and a P value less than 0.05 was considered significant.
Results COX-2 was expressed in tumor cells in 92% of examined desmoid cases (16/17). Toluidine blue staining has shown that COX-2 immunostained cells do not coincide with the few metachromatically stained mast cells in co-localized sections. ERβ was expressed in 67.1% of tumor cells in desmoid cases (11/17); eight cases displayed high ERβ expression and three cases displayed low ERβ expression. No significant correlation was detected between ERβ or COX-2 immunohistochemical expression and patient’s age, sex, tumor size, site, margins status, and recurrence history (P>0.05).
Conclusion This study confirmed the immunohistochemical expression of COX-2 and ERβ in tumor cells of the majority of studied desmoid cases. These results introduce COX-2 and ERβ as potential therapeutic targets in desmoid tumors. Further studies with a large sample size and follow-up are recommended to validate the current results.
