        Genetic parameters for daily milk somatic cell score and relationships with yield traits of primiparous Holstein cattle in Iran

        ( Khabat Kheirabadi ),( Mohammad Razmkabir ) 한국동물자원과학회(구 한국축산학회) 2016 한국축산학회지 Vol.58 No.10

        Background: Despite the importance of relationships between somatic cell score (SCS) and currently selected traits (milk, fat and protein yield) of Holstein cows, there was a lack of comprehensive literature for it in Iran. Therefore we tried to examine heritabilities and relationships between these traits using a fixed-regression animal model and Bayesian inference. The data set consisted of 1,078,966 test-day observations from 146,765 primiparous daughters of 1930 sires, with calvings from 2002 to 2013. Results: Marginal posterior means of heritability estimates for SCS (0.03 ± 0.002) were distinctly lower than those for milk (0.204 ± 0.006), fat (0.096 ± 0.004) and protein (0.147 ± 0.005) yields. In the case of phenotypic correlations, the relationships between production and SCS were near zero at the beginning of lactation but become increasingly negative as days in milk increased. Although all environmental correlations between production and SCS were negative (-0.177 ± 0.007, -0.165 ± 0.008 and -0.152 ± 0.007 between SCS and milk, fat, and protein yield, respectively), slightly antagonistic genetic correlations were found; with posterior mean of relationships ranging from 0.01 ± 0.039 to 0.11 ± 0.036. This genetic opposition was distinctly higher for protein than for fat. Conclusion: Although small, the positive genetic correlations suggest some genetic antagonism between desired increased milk production and reduced SCS (i.e., single-trait selection for increased milk production will also increase SCS).

        Brain-derived Neurotrophic Factor and High Sensitive C-reactive Protein in Bipolar Depression and Unipolar Depression: The Practical Usage as a Discriminatory Tool

        Shima Shahyad(Shima Shahyad ),Gholam Reza Kheirabadi(Gholam Reza Kheirabadi ),Gila Pirzad Jahromi(Gila Pirzad Jahromi ),Muhammad Massaly(Muhammad Massaly ) 대한정신약물학회 2023 CLINICAL PSYCHOPHARMACOLOGY AND NEUROSCIENCE Vol.21 No.1

        Objective: Brain-derived neurotrophic factor (BDNF) and high sensitive C-reactive protein (hs-CRP) have been reported to play roles in depression and bipolar disorder (BD). However, the probable discriminatory properties of these biologic markers are less investigated. We aimed to assess the serum BDNF and hs-CRP levels among Iranian patients with major depressive disorder (MDD) and BD during a depressive episode and investigate the optimum cut-off point for differential diagnosis of BD and MDD. Methods: We recruited 30 patients with MDD, 30 with BD in depressive mood and 30 healthy comparators. Blood sample was taken from each participant to measure BDNF and hs-CRP levels. We also used receiver operating characteristic (ROC) curve analysis to find an optimal cut-off point for differentiating MDD from BD according to pre-defined variables. Results: The mean age of total study population was 37.3 ± 5.0 years (males: 49%). BDNF was significantly lower in patients with BD, followed by MDD subjects and healthy controls 541.0 ± 601.0 pg/ml vs. 809.5 ± 433.3 pg/ml vs. 1,482.1 ± 519.8, respectively, p < 0.001). The area under curve of ROC curve analysis for BD versus MDD was 0.704 (95% confidence interval: 0.564−0.844, p = 0.007). We also found that the BDNF cut-off value of 504 could appropriately distinguished BD from MDD (sensitivity: 73%, specificity: 70%). No significant association were identified in terms of hs-CRP levels. Conclusion: Patients suffering from BD had lowest BDNF levels compared to MDD or healthy adults and this biomarker could play a practical role differentiating MDD from BD. Several studies are required confirming our outcomes.

      • Investigating Sexual Function and Affecting Factors in Women with Breast Cancer in Iran

        Shandiz, Fatemeh Homaee,Karimi, Fatemeh Zahra,Rahimi, Nafiseh,Abdolahi, Mahboubeh,Anbaran, Zahra Khosravi,Ghasemi, Mina,Mazlom, Seyed Reza,Kheirabadi, Aghileh Nasaghchi Asian Pacific Journal of Cancer Prevention 2016 Asian Pacific journal of cancer prevention Vol.17 No.7

        Background: Since the breast is strongly relevant to sexual desire, and physical and sexual attractiveness, the high prevalence of breast cancer (BC) in Iran and long-term survival of patients experiencing side effects means that measures to identify associated sexual problems are necessary. Therefore, this study was conducted to assess sexual function and affecting factors in women with BC. Materials and Methods: This cross-sectional study was performed on 94 women with BC, referred to Imam Reza (AS) Hospital, Mashhad, Iran, in 2014. The data were collected through demographic and clinical questionnaires and also a sexual function questionnaire and analyzed using SPSS version 16. Results: The total score of women's sexual function was about $24.3{\pm}4.41$. Of the total, 63 (71.3%) reported sexual dysfunction, for example reduced satisfaction or more pain. Age was the only significantly related factor. Conclusions: Breast cancer can adversely affect women's sexual function and decrease quality of life. Thus, taking measures to overcome women's sexual problems are necessary.
