In this paper, we consider a heat engines composed of two interactional qubits with spin-orbit interaction (Dzyaloshinskii–Moriya (DM)) subject to an external magnetic field, so that each qubit is coupled with cold or hot source. One intention of this work is to investigate the following question: is it possible the effects of DM lead to improve basic thermodynamic quantities in this heat engine are coupled to local environments that are not necessarily at equilibrium? Moreover, we study whether or not quantum correlations can be helpful in the performance of quantum work engines. For this end, we investigate the effects of the temperature and the interaction rate of each qubit with its surrounding environment on quantum correlations such as quantum coherence and quantum discord and quantum entanglements, as well as the generated work. Finally we compare three quantum correlations (entanglement, discord, and coherence) with thermodynamic parameters and show that the output work is positive for what values of the magnetic field so that this cycle can be considered as a thermal machine.
Background: The process of steroidogenesis is crucial to the normal function of the ovaries. In individuals with polycystic ovary syndrome (PCOS), the activity of related enzymes in this process is disrupted. In the present study, the effect of trans-anethole was investigated on gene expression of steroidogenesis enzymes in PCOS model rats. Materials and Methods: In this experimental study, thirty female rats were divided into six groups (n=5 per group). Fifteen PCOS rats in three groups received intraperitoneal injections of distilled water, 50, and 80 mg/kg of trans-anethole, respectively. Also, 15 intact rats in three groups received intraperitoneal injections of distilled water, 50, and 80 mg/kg trans-anethole. The expression of steroidogenesis genes was determined using real-time reverse transcription polymerase chain reaction. Results: The mRNA level of Cyp19 significantly increased in intact rats receiving 80 mg/kg trans-anethole compared to the control group. The Cyp19 level in PCOS groups was significantly reduced compared to the control group. The mRNA level of Cyp19 in PCOS groups that resived 50 or 80 mg/kg trans-anethole increased compared to PCOS rats, but this increase was not statistically significant. The mRNA level of Cyp17 did not significantly change in intact and PCOS rats that received trans-anethole compared to the control group. Conclusion: Trans-anethole may improve PCOS complications due to its involvement in regulating steroidogenesis.
