Galaxamide alleviates cisplatin-induced premature ovarian insufficiency via the PI3K signaling pathway in HeLa tumor-bearing mice.

Background: It is challenging to improve the effects of chemotherapy and reduce its adverse impact on the ovaries. Our previous study suggested that the combination of galaxamide could enhance the antitumor effect of cisplatin (CIS) in HeLa cell xenograft mice. However, their potential effects on ovarian tissues remain unknown.

Exaggerated placental site in a cesarean scar: Misdiagnosed as gestational trophoblastic neoplasia: A case report.

The present study reports a rare case of an exaggerated placental site (EPS) in a caesarean scar that was misdiagnosed as gestational trophoblastic neoplasia (GTN) by imaging, resulting in unnecessary surgical treatment. A 38-year-old woman underwent hysteroscopic resection of a cesarean scar pregnancy (CSP). The patient's serum β-human chorionic gonadotropin (β-hCG) level was elevated (76,196 mIU/ml) at the 24-day postoperative follow-up visit.

Research on the Fault Diagnosis Method of an Internal Gear Pump Based on a Convolutional Auto-Encoder and PSO-LSSVM.

The raw signals produced by internal gear pumps are susceptible to noises brought on by mechanical vibrations and the surrounding environment, and the sample count collected during the various operating periods is not distributed evenly. Accurately diagnosing faults in internal gear pumps is significantly complicated by these factors. In light of these issues, accelerated life testing was performed in order to collect signals from an internal gear pump during various operating periods.

End-to-End Continuous/Discontinuous Feature Fusion Method with Attention for Rolling Bearing Fault Diagnosis.

Mechanical equipment failure may cause massive economic and even life loss. Therefore, the diagnosis of the failures of machine parts in time is crucial. The rolling bearings are one of the most valuable parts, which have attracted the focus of fault diagnosis.

Numerical simulation and experimental evaluation of flow ripple characteristics of Truninger pump.

Compared with involute internal gear pumps and gerotor pumps, lower flow ripple is the main advantage of Truninger pumps. Understanding the flow ripple mechanism and characteristics is of great significance to guide the design and manufacture of this type of pump. In this paper, the theoretical flow ripple and flow ripple rate expressions of the pump are derived based on the vector ray method, and the effects of variations of the design parameters of the pump on the theoretical flow ripple characteristics are studied.

Palladium (III) Fluoride Bulk and PdF/GaO/PdF Magnetic Tunnel Junction: Multiple Spin-Gapless Semiconducting, Perfect Spin Filtering, and High Tunnel Magnetoresistance.

Spin-gapless semiconductors (SGSs) with Dirac-like band crossings may exhibit massless fermions and dissipationless transport properties. In this study, by applying the density functional theory, novel multiple linear-type spin-gapless semiconducting band structures were found in a synthesized R 3 - c -type bulk PdF compound, which has potential applications in ultra-fast and ultra-low power spintronic devices. The effects of spin-orbit coupling and on-site Coulomb interaction were determined for the bulk material in this study.
