It is commonly claimed that the folk category of emotion does not constitute a natural kind, due to the significant compositional differences between its members, especially basic and complex emotions. Arguably, however, this conclusion stems from the dualistic philosophical anthropology underlying the discussion, which presupposes a metaphysical "split" between mind and body. This is the case irrespective of whether a traditional or biological (homology-based) approach to natural kinds is adopted. Since the origins of this increasingly disputed anthropology can ultimately be traced to Descartes' substance dualism, its adverse effects can likewise be addressed using a contemporary theory of emotion developed from Spinoza, one of Descartes' earliest critics on this issue. Furthermore, a Spinozistic view of emotion accords with the recent shift to a hierarchical approach to homology, which recognises that the evolutionary lineage of complex biological units should be traced via relational qualities rather than physical characteristics. Both the Spinozistic approach to emotion and the hierarchical approach to homology show that the compositional variation in the folk category of emotion does not necessarily preclude it from constituting a natural kind.
  The objective of this investigation was to determine the daily follitropin delta dose (µg) providing a similar ovarian response to 150IU/day follitropin alfa.
 
  The study was a post-hoc analysis of ovarian response in 1591 IVF/intracytoplasmic sperm injection (ICSI) patients undergoing ovarian stimulation in a gonadotrophin-releasing hormone antagonist protocol in two recent randomized, assessor-blind, controlled trials in the development programme for follitropin delta a phase II dose-response trial with a reference arm of a fixed daily dose of 150IU follitropin alfa throughout stimulation, and a phase III efficacy trial with a comparator arm of 150IU/day follitropin alfa as a starting dose.
 
  Daily follitropin delta doses of 10.0µg (95% confidence interval [CI] 7.9-12.8) and 10.3µg (95% CI 9.7-10.8) yielded the same number of oocytes as 150IU/day follitropin alfa for all patients participating in the phase II and III trials, respectively. When analysing patients with either normal or high ovarian reserve (based on serum anti-Mullerian hormone ≥15pmol/l) and no dose changes, the same number of oocytes was obtained with 150IU/day follitropin alfa and daily doses of follitropin delta of 9.7µg (95% CI 7.5-12.4) and 9.3µg (95% CI 8.6-10.1) in the two trials.  https://www.selleckchem.com/products/cdk2-inhibitor-73.html  Daily follitropin delta doses in the range 9.5-10.4µg were consistently estimated to correspond to 150IU/day follitropin alfa for serum oestradiol concentration and number of follicles ≥12mm at the end of stimulation across analysis populations in the phase III trial.
 
  A daily follitropin delta dose of 10µg provides a similar ovarian response to 150IU/day follitropin alfa in IVF/ICSI patients.
 A daily follitropin delta dose of 10 µg provides a similar ovarian response to 150 IU/day follitropin alfa in IVF/ICSI patients.The value of artificial intelligence to benefit infertile patients is a subject of debate. This paper presents the experience of one aspect of artificial intelligence, machine learning, coupled with patient empathy to improve utilization of assisted reproductive technology (ART), which is an important aspect of care that is under-recognized. Although ART provides very effective options for infertile patients to build families, patients often discontinue ART when further treatment is likely to be beneficial and most of these patients do not achieve pregnancy without medical aid. Use of ART is only in part dependent on financial considerations; stress and other factors play a major role, as shown by high discontinuation rates despite reimbursement. This commentary discusses challenges and strategies to providing personalized ART prognostics based on machine learning, and presents a case study where appropriate use of such prognostics in ART centres is associated with a trend towards increased ART utilization.Oocyte vitrification is an attractive and efficient option in the long-term management of endometriosis patients. Which women would benefit from banked oocytes when pregnancy is attempted, and whether oocyte vitrification should be carried out before or after the surgical management of endometriosis, is still debated. On the basis of recent data, and in the absence of cost-effective modelling, a personalized strategy should assess crucial variables, such as type of surgery, effect on oocyte yield and the huge heterogeneity of the clinical scenarios possibly requiring surgery. Research into a more tailored approach to maximize the result of each available intervention, e.g. hormones, surgery, assisted reproductive technology or their combination to prevent infertility and reduce the actual burden of personal and societal cost of the disease, is recommended.
  Long non-coding RNA (lncRNA) do not show protein translation but do have gene regulatory functions in several disease states. Studies have shown that lncRNA differ in overweight women with polycystic ovary syndrome (PCOS), increased insulin resistance and hyperandrogenaemia. The objective of this study was to determine the lncRNA in serum in age- and weight-matched non-obese women with and without PCOS.
 
  In this prospective pilot cohort study, lncRNA were measured in serum in 13 non-obese women with PCOS and 10 control women undergoing IVF.
 
  There was no difference between groups in terms of age, body mass index or insulin resistance. Women with PCOS showed a higher free androgen index (FAI; P = 0.03) and anti-Müllerian hormone (AMH) concentration (P = 0.001). A total of 29 lncRNA (P≤0.05) differed between PCOS groups. lncRNA AC095350.1 correlated with age (r = 0.79, P = 0.04), but no correlation was seen between the significantly different lncRNA and FAI or AMH values. Functional pathway assessment using the Ingenuity Pathway Assessment tool showed no relationships for the lncRNA.
 
  lncRNA in serum differed between non-obese women with PCOS and the control group, and the pattern of expression differed from that reported in obese women with PCOS from the same ethnic population; however, it but did not correlate with androgen or insulin resistance.
