Summary: A novel strategy utilizing time-lapse flow cytometry (TLFC) was developed to determine capacitation-related physiological parameters in human sperm. TLFC was found to be a robust method for measuring absolute values of membrane potential and intracellular pH, as well as qualitatively evaluating changes in intracellular calcium concentration. Analysis of sperm samples from two types of donors revealed significant differences in these key physiological parameters between known paternity and no-known paternity samples.

Summary: Using two complementary proteomic methods, this study identified 57 differentially abundant proteins in fertile and subfertile rooster sperm. These proteins are involved in various molecular pathways such as flagellum integrity and movement, mitochondrial functions, sperm maturation, storage in female tract, and oocyte-sperm interaction. The data provides new insights into the complexity of male fertility in chickens and suggests the use of a combination of markers for predicting male fertility.

Summary: In this study, the effects of Thymoquinone nanoparticles (TQNPs) on frozen-thawed buffalo sperm were investigated. TQNPs supplementation improved sperm quality, including membrane integrity and progressive motility. TQNPs also reduced oxidative stress and improved antioxidant capacity. Additionally, TQNPs decreased acrosome exocytosis and apoptosis-like changes. The use of TQNPs-treated sperm resulted in higher non-return rates in buffalo cows, indicating improved fertility.

Summary: The study investigated the role of mitochondrial activity in sperm fertilizing ability during capacitation in mice, finding that MMP increase depends on capacitation and H89-sensitive events, high MMP is associated with sperm motility, and mitochondrial function is needed mainly for zona pellucida penetration. Additionally, mitochondrial activity is fundamental for sperm function in fertilization.

Summary: This study demonstrated the existence of positive genetic covariance between a male secondary sexual trait, such as ornament size, and competitive fertilization success. The findings suggest that indirect postcopulatory sexual selection may magnify net selection on ornamental trait expression under certain conditions.

Summary: In this study, the relativistic R-matrix method is used to investigate the electron-impact broadening of spectral lines produced by highly charged Ar XV ions. The results considering resonance structures differ significantly from the distorted wave approach. A new empirical formula with a correction term is proposed to account for the effect of resonances in a relatively wide range of plasma conditions. The fitting parameters for all 47 calculated transitions are provided, with an estimated accuracy within 1%.

Summary: Placental dysfunction refers to impaired placental function and inadequate supply of oxygen and nutrients to the fetus, resulting in fetal growth restriction. Deficient trophoblast syncytialization, inadequate trophoblast invasion, and impaired vascular remodeling contribute to placental dysfunction. Abnormal expression of proteins and signaling pathways involved in trophoblast syncytialization has been found in the placentas of pregnancies complicated by intrauterine growth restriction (IUGR).

Summary: This study reports the reactivity properties of Cu(III)-CF3 compounds with anilines, showing distinct reactivities based on their basicity, resulting in the formation of formamides or hydrazines. This is achieved through the competing generation of difluorocarbene and N-centered radicals, controlled by the basicity of the reaction solution. The study demonstrates the unusual use of high-valent Cu(III) trifluoromethyl compounds as hydrogen-abstracting reagents for dehydrogenative reactions.

Summary: This study reports the geminal amino- and oxy-trifluoromethylation of ortho-ethynyl anilines/ phenols using phenCu(III)(CF3)(3), which provides a concise and controllable synthesis of valuable trifluoromethylated N and O-heterocyclic compounds. The method circumvents the regioselectivity issue often encountered in C H trifluoromethylation of arenes/heteroarenes and suppresses the competing vicinal fluoro-trifluoromethylation of terminal alkynes. The synthetic value of Cu(III) CF3 compounds in medicinal chemistry is highlighted.

Summary: V/LiF is an important window material for investigating phase transition of materials under ultra-high pressure, which is a fundamental issue in condensed matter physics. However, the large mismatch in lattice and thermal properties makes vanadium growth on LiF a big challenge. In this study, over 1.5 μm thick vanadium films were successfully grown on LiF using facing target sputtering (FTS), and transmission electron microscopy (TEM) observation revealed vertically well-aligned columnar crystals with numerous micro-sized gaps in the grown vanadium films. Particle-in-cell Monte Carlo collision (PIC-MCC) and Kinetic Monte Carlo (KMC) methods were used to simulate plasma discharge behavior, sputtered atom transport, and film growth to understand the deposition mechanism. A growth model of the vanadium film was established based on experimental and simulation results, and the micro-sized gaps in the columnar crystals were found to contribute to the release of residual stresses caused by the large mismatch, which can be explained by the grain boundary relaxation model.

Summary: In this paper, a systematic investigation was conducted on the correlation of processing parameters, plastic deformation, and mechanical properties of the machined surface layer for hardened H13 steel. The results indicate that edge micro-geometry significantly influences the depth of the plastic deformation layer, and the automated ball indentation (ABI) technique was used to assess the mechanical properties of the machined surface layers. The study reveals the relationship between processing parameters, depth of plastic deformation, and mechanical properties.

The <010> orientation is closely related to the higher stability of oxygen close-packed planes under O-rich condition. The <010>-oriented ss-Ga2O3 film-based MSM type detector exhibits ultra-fast response speed.

Summary: The study aims to investigate the effects of growth differentiation factor-15 (GDF-15) on all-cause death, cardiovascular death, MI, and stroke in patients with coronary artery disease (CAD). The results showed that patients with elevated GDF-15 levels had significantly increased risks of all-cause death, cardiovascular death, and MI, but a lower predictive effect on stroke. Further studies are needed to explore the association between GDF-15 and stroke outcome.
