Ovarian Cyst, Dairy cows, Stress

Ovarian Cyst Ovarian cyst is an abnormal follicular structure that forms due to ovulation failure, reaching larger diameter than ovarian follicle and persists for ≥10 days. This structure may regress spontaneously, stay permanently or be luteinized (Ball & Peter, 2004; Noakes et al., 2018), (Figure. 1). Ovarian cyst is more common in dairy than beef cows, especially in high milk production cows. It often occurs during the postpartum period (Hafez & Hafez, 2000; Noakes et al., 2018, Peter et al., 2009). Peter et al. (2018) consider the ovarian cyst as a development of anestrous case of persistence structures of dominant follicles, but Noakes et al. (2018) do not consider the importance of CL absence in this case. The failure in luteinizing hormone (LH) releasing mechanism is the most evident cause of ovarian cyst which is not related to deficiency in Gonadotropin-releasing hormone (GnRH) but it is related to low sensitivity of hypothalamic-pituitary axis to elevated secretion of

  Thermotolerance and plasticity of camel somatic cells exposed to acute and chronic heat stress   In this work Saadeldin et al., (2020) studied the effect of acute and chronic heat stress (HS) on camel and porcine granulosa cells. The study included morphological, proteomic and redox changes induced by HS. The changes in gene expression, morphological changes-involved pathways and protection mechanisms were studied too. It is a complete research that is a base for future HS studies.     Saadeldin, I. M., Swelum, A. A. A., Elsafadi, M., Mahmood, A., Osama, A., Shikshaky, H., ... & Magdeldin, S. (2020).
