Abstract: Although antiphospholipid (APL) antibodies are still not clearly known, yet they have association with thromboembolic events associated with hepatitis C virus (HCV) infection. Moreover, high percent of HCV infections and thromboembolic risk was associated among thalassemic patients. So our aim was to screen and evaluate the significance of ACL and anti β-2 glycoprotein seroprevelance among patients receiving repeated blood transfusions, in patients with infectious diseases as chronic HCV disorders, and in healthy subjects resident in Egypt, a tropical country endemic for hepatitis and to evaluate these tests as rapid markers for early detection of thrombotic HCV infection among chronic liver disorders and cases receiving repeated blood transfusion aiming at early anticoagulant therapy.The study was carried out on 70 patients attending Tropical, Hepatology and Hematology departments in Alexandria Main University Hospital, Egypt as well as 30 healthy subjects served as controls. Group I; 35 chronic liver disorders as chronic HCV, cirrhosis and Hepatocellular carcinoma(HCC) diagnosed by clinical, ultrasound and histopathology. Group II ; 35 receiving repeated blood transfusion as thalassemia. Group III; healthy relatives –ve for HCV antibody of matched age and sex. Both markers were screened by commercial enzyme immunosorbant assays (ELISA) (Calbiotech,USA). Our results revealed that patients with chronic HCV infection had higher anticardiolipin (ACL) IgG and antibeta2GP1 IgG compared to healthy controls. (26.6%) 8 patients from group I had high ACL IgG compared to 6 patients (20%) of group II .The study also revealed that anti β-2 glycoprotein IgG was higher among Group I and II compared to controls group III. Group I was higher than group II. Three patients (10%) of group I had high antiβ2 glycoprotein1 IgG compared to 2 patients (6.6%) among group II . We can conclude that anticardiolipin (ACL)alone is not diagnostic for thrombosis & it should be accompanied with antibeta(β )2glycoprotein-1 in serum of the same patient to be considered a cause of thrombosis in chronic HCV patients. So, ACL alone can not be considered rapid marker of thrombosis in HCV positive patients. We recommend anti β2 glycoprotein as a biomarker predicting thrombotic HCV infection

Abstract: A total of 1682 heterotrophic nitrogen removal (HNR) bacteria isolated from sedimentary and water of striped catfish ponds were classified in four kinds of heterotrophic ammonia-oxidizing bacteria (402 isolates), nitrite-oxidizing bacteria (438 isolates), nitrate-oxidizing bacteria (444 isolates) and heterotrophic nitrifying and denitrifying bacteria (398 isolates). The virtually complete 16S rRNA gene was PCR amplified and sequenced. The sequences from the selected HNR bacteria showed high degrees of similarity to those of the GenBank references strains (between 97% and 99.8%). Phylogenetic trees based on the 16S rDNA sequences displayed high consistency, with nodes supported by high bootstrap (500) values. These presumptive HNR isolates were divided four groups that included members of genera Arthrobacter, Corynebacterium, Rhodococcus (high G+C content gram-positive bacteria), Bacillus (low G+C content gram-positive bacteria) and Pseudomonas (gram-negative bacteria). Based on Pi value (nucleotide diversity), heterotrophic ammonium-oxidizing bacteria group had highest values and heterotrophic nitrifying-denitrifying bacteria group had the lowest values and Theta values (per sequence) from S of SNP for DNA polymorphism showed that heterotrophic nitrate-oxidizing bacteria group had the highest theta values in comparison of three groups. The present study, the HNR bacteria from sedimentary and water of striped catfish ponds, showed a very diverse community of HNR bacteria with a relatively high number of species involved in sedimentary and water samples and many isolates have nitrogen utilization ability at high concentration (800 – 1200 mM) and high G+C gram-positive bacteria strain occupied higher than low G+C gram-positive bacteria strain.

Abstract: A total of 2318 heterotrophic nitrogen removal (HNR) bacteria isolated from piggery wastes (after biogas container) were classified in four kinds of heterotrophic ammonia-oxidizing bacteria (569 isolates), nitrite-oxidizing bacteria (580 isolates), nitrate-oxidizing bacteria (600 isolates) and heterotrophic nitrifying and denitrifying bacteria (569 isolates). The virtually complete 16S rRNA gene was PCR amplified and sequenced. The sequences from the selected HNR bacteria showed high degrees of similarity to those of the GenBank references strains (between 97% and 99.8%). Phylogenetic trees based on the 16S rDNA sequences displayed high consistency, with nodes supported by high bootstrap (500) values. These presumptive HNR isolates were divided four groups that included members of genera Arthrobacter, Corynebacterium, Rhodococcus (high G+C content gram-positive bacteria), Staphylococcus, Bacillus (low G+C content gram-positive bacteria) and Klebsiella (gram-negative bacteria). Based on Pi value (nucleotide diversity), heterotrophic ammonium-oxidizing bac-teria group had highest values and heterotrophic nitrifying-denitrifying bacteria group had the lowest values and Theta values (per sequence) from S of SNP for DNA polymorphism showed that heterotrophic nitrate-oxidizing bacteria group had the highest theta values in comparison of three groups. The present study, the HNR bacteria from piggery wastes, showed a very diverse community of HNR bacteria with a relatively high number of species involved in solid-wastewater samples and many isolates have nitrogen utilization ability at high concentration (800 – 1200 mM) and high G+C gram-positive bacteria strain occupied higher than low G+C gram-positive bacteria strain.

Abstract: A mixture of antioxidants found in a commercial food supplement called Citozym (CIZ), showed a preventive capability on experimental prostate hyperplasia induced by testosterone propionate (TP) in C57BL6/N mice. Treatments by CIZ were given orally and started 10 days before the induction of prostate hyperplasia. TP significantly increased prostate size and weight ratio, and this induced increase was significantly inhibited in CIZ-treated mice in comparison with positive controls in a dose-dependent manner. We conclude that CIZ can prevent TP-induced prostate hyperplasia and therefore may be beneficial in the management of benign prostatic hyperplasia.
