BACKGROUND An isthmocele is a scar defect in the uterine wall due to a cesarean section. Its prevalence is unknown,but it has been associated with secondary ***,we present a case where the patient suffered from an isthmocele that was associated with persistent hydrometra,which developed during in vitro *** SUMMARY The patient underwent hysteroscopic surgery,which successfully resolved the isthmocele as well as the hydrometra. Afterward,two high-quality,euploid embryos,determined by morphological assessment and pre-implantation genetic diagnostic testing,were transferred. This resulted in uterine pregnancy,as determined byserum β-human chorionic gonadotropin levels on day 14(180 m U/mL) and ultrasound-confirmed presence of a gestational sac with a positive embryocardia at week 6. The pregnancy reached 36 wk without any complications,and the product was born in good health. We report a successful isthmocele treatment in a patient with secondary infertility,in which the isthmocele was the cause of persistent *** Hydrometra caused by secondary cesarean is an infertility factor,which can be corrected by hysteroscopy plus ablation of the isthmocele.

In this paper we pursue the study of the best approximation operator extended from L~Φ to L~φ, where φ denotes the derivative of the function Φ. We get pointwise convergence for the coefficients of the extended best approximation polynomials for a wide class of function f, closely related to the Calder′on–Zygmund class t_m^p(x) which had been introduced in 1961. We also obtain weak and strong type inequalities for a maximal operator related to the extended best polynomial approximation and a norm convergence result for the coefficients is derived. In most of these results, we have to consider Matuszewska–Orlicz indices for the function φ.

The purpose of this review article is to present some of the recent contributions that show the use of thermo-dynamics to describe biological systems and their evolution, illustrating the agreement that this theory pre-sents with the field of evolution. Organic systems are described as thermodynamic systems where entropy is produced by the irreversible processes, considering as an established fact that this entropy is eliminated through their frontiers to preserve life. The necessary and sufficient conditions to describe the evolution of life in the negentropy principle are established. Underlining the fact that the necessary condition requires formulation, which is founded on the principle of minimum entropy production for open systems operating near equilibrium. Other formulations are mentioned, particularly the information theory, the energy inten-siveness hypothesis and the theory of open systems far from equilibrium. Finally suggesting the possibility of considering the lineal formulation as a viable alternative;that is, given the internal constrictions under which a biological system operates, it is possible that the validity of its application is broader than it has been suggested.
