Implementing accelerometer technologies in beef operations is an alternative to increase precision in estrous detection. We hypothesized that (1) the accelerometer algorithm has similar accuracy in detecting behavioral estrus as does visual observation of pressure-sensitive sensors (estrus patches) in grazing beef cows; (2) variables measured by the accelerometer, such as estrus intensity, are associated with hormonal, ovarian, and uterine variables monitored before, during, and after estrus; and (3) the accelerometer variables are associated with the probability of pregnancy in grazing beef cows submitted to embryo transfer (ET). Fifty cows were fitted with accelerometer and patches to detect estrus after a synchronization protocol in eight subsequent rounds.

This study investigated, for the first time, the alterations in the uterine echotexture and blood flow in cyclic and acyclic (inactive ovary) goats using ultrasonography. The study aimed also to evaluate the metabolomic changes in the plasma of cyclic and acyclic goats. Furthermore, the histopathological approach was applied to the specimens of the uterus to validate the findings of this study.

Objective: Understanding the relationship between genetic structure and the molecular changes involved in endometrial cancer (EC) provides an opportunity to personalize treatments and incorporate targeted therapies.
Method: We compared cytogenetic and molecular features observed in tumoral and adjacent healthy tissue endometrium samples in EC patients.
Results: Non-clonal chromosome aberrations (NCCAs) frequently in patients with EC, especially in 10,15,17,22, X chromosomes and were monitored in 73.
Oncologic and pregnancy outcomes of fertility-sparing treatment with medroxyprogesterone acetate in women with premalignant and malignant endometrial lesions: A case series.

Introduction: Current trends of delaying childbearing and the increasing incidence of endometrial cancer in nulliparous woman necessitate research and development of fertility sparing treatments. Hormonal therapy with progestins offers an alternative to surgical treatment for a select group of patients of reproductive-age, who wish to preserve their reproductive potential.
Materials And Methods: The study evaluates the effectiveness of medroxyprogesterone acetate therapy in patients with early-stage endometrial cancer, atypical endometrial hyperplasia or atypical polypoid adenomyoma, seeking to preserve fertility.
Recent trends and impact of localized surface plasmon resonance (LSPR) and surface-enhanced Raman spectroscopy (SERS) in modern analysis.

An optical biosensor is a specialized analytical device that utilizes the principles of optics and light in bimolecular processes. Localized surface plasmon resonance (LSPR) is a phenomenon in the realm of nanophotonics that occurs when metallic nanoparticles (NPs) or nanostructures interact with incident light. Conversely, surface-enhanced Raman spectroscopy (SERS) is an influential analytical technique based on Raman scattering, wherein it amplifies the Raman signals of molecules when they are situated near specific and specially designed nanostructures.
