Changes in blood flow in ovine follicles and serumconcentration of estradiol 17 beta (E2) and nitric oxide (NO) around the time of ovulation in Ossimi ewes

Research Abstract
The aim of the present study was to examine the relation between follicular blood flow of the ovulatory follicle and the levels of serum E2 and nitric oxide (NO) in Ossimi ewe. Seven cyclic ewes were synchronized with a double injection PGF2. The follicular wave was examined daily until ovulation (disappearance of the large dominant follicle ultrasonographically) with transrectal color Doppler ultrasonography (8–10 MHz linear array transducer). The number of recruited follicles was 4.8 ± 0.9 (3–8 follicles) with diameter of 2.8 ± 0.1 mm. The interval from PGF2 injection to follicle deviation was 2.35 ± 0.07 days. The diameter of the first largest follicle (LF1) at recruitment day was 4 ± 0.3 mm while the diameter of the second largest follicle (LF2) was 3.7 ± 0.1 mm. The diameter of LF1 at the day of deviation was 5.1 ± 0.5 mm while the diameter of the LF2 was 4 ± 0.7 mm. The diameter of the ovulatory follicle was 6.1 ± 0.5 at day of ovulation. We detected the blood flow area of the ovulatory follicle at D2. At ovulation, the blood flow area and blood flow area percent increased significantly to be 11.9 ± 0.6 mm2 and 44 ± 3.4% respectively. The results showed a positive correlation between E2 and NO (r = 0.85, P 0.009). Both increased concomitantly with the diameter of the ovulatory follicle. Besides, NO and E2 reached a maximum level at ovulation (12.1 ± 1.8 ng/ml and 16.4 ± 1.7 pg/ml respectively).

Persistence of TEL-AML1 fusion gene as minimal residual disease has no additive prognostic value in CD 10 positive B-acute lymphoblastic leukemia: a FISH study

Research Abstract
Objectives : We have analyzed t(12;21)(p13:q22) in an attempt to evaluate the frequency and prognostic significance of TEL-AML1 fusion gene in patients with childhood CD 10 positive B-ALL by fluorescence in situ hybridization (FISH). Also, we have monitored the prognostic value of this gene as a minimal residual disease (MRD). Methods: All bone marrow samples of eighty patients diagnosed as CD 10 positive B-ALL in South Egypt Cancer Institute were evaluated by fluorescence in situ hybridization (FISH) for t(12;21) in newly diagnosed cases and after morphological complete remission as a minimal residual disease (MRD). We determined the prognostic significance of TEL-AML1 fusion represented by disease course and survival. Results: TEL-AML1 fusion gene was positive in (37.5%) in newly diagnosed patients. There was a significant correlation between TEL-AML1 fusion gene both at diagnosis (r = 0.5, P = 0.003) and as a MRD (r = 0.4, P = 0.01) with favorable course. Kaplan-Meier curve for the presence of TEL-AML1 fusion at the diagnosis was associated with a better probability of overall survival (OS); mean survival time was 47 ± 1 month, in contrast to 28 ± 5 month in its absence (P = 0.006). Also, the persistence at TEL-AML1 fusion as a MRD was not significantly associated with a better probability of OS; the mean survival time was 42 ± 2 months in the presence of MRD and it was 40 ± 1 months in its absence. So, persistence of TEL-AML1 fusion as a MRD had no additive prognostic value over its measurement at diagnosis in terms of predicting the probability of OS. Conclusion: For most patients, the presence of TEL-AML1 fusion gene at diagnosis suggests a favorable prognosis. The present study suggests that persistence of TEL-AML1 fusion as MRD has no additive prognostic value.

Diagnostic performance and predictive value of rheumatoid factor anti-cyclic-citrullinated peptide antibodies and HLA-DRB1 locus genes in rheumatoid arthritis

Research Abstract
Background: We evaluated the significance of the genes, defined as DRB1*04 or DRB1*01, in rheumatoid arthritis (RA) patients. We focused on the role of genetic and serologic markers to predict disease activity and destructive process of joints. Methods: Sixty patients with RA were examined. Radiographic changes were evaluated by (Larsen score) and disease activity was measured by disease activity score 28 (DAS28). The markers analyzed were: erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), rheumatoid factor (RF), anti-cyclic citrullinated peptides (anti-CCP2) and HLA-DRB1 alleles typed by PCR. Results: In this study, anti-CCP antibodies, CRP, RF and AKA were detected in 83.3%, 56.7%, 71.7% and 52% of patients respectively. HLA-DRB1*01 was found in 45% of patients and 35% of them had one or two HLA-DRB1*04 alleles. According to DRB1*04 subtypes, (DRB1* 0405) was present in of 80% them. For prediction of grade of activity, the independent predictors were anti- CCP (OR 19.6), and DRB1*04 positive allele (OR 5.1). The combination of DRB1*04 + anti-CCP antibodies gave increase in the specificity and positive predictive value to 92% and 90 respectively. As regards to the prediction of radiological joint damage, the independent predictors were HLADRB1* 04, HLA-DRB1*01, RF, and CRP > 18 (OR 5.5, 4.5, 2.5, 2.0 respectively). Conclusion: Our findings suggest that anti-CCP2 is superior to RF for the detection of RA and provided predictive information on joint destruction and disease activity. The presence of RA associated antibodies (ACCP or RF) and/or the SE genes are indicative for a poorer radiological outcome and higher grade of activity.
