Performance Enhancement for Non-Line-of-Sight Ultraviolet Communication Systems

Da-Jiang Ge, Guangbin Zhou, Jie Li

This paper proposes a non-line-of-sight (NLOS) ultraviolet (UV) communication system based on non-coherent two-dimensional optical code division multiple access (OCDMA). Eye diagram analysis is employed to assess the system's performance in terms of transmission distance and noise resilience. Comparative experiments between the …

TW ‐7 Alleviate Apoptosis of Embryos Derived From Vitrified MII Oocytes by Downregulation of JNK Signaling in Mice

Yaozong Wei, Jianpeng Qin, Xiangyi Chen, Fan Xu et autres

ABSTRACT Previous studies have shown that walnut‐derived peptide TW‐7 is a powerful antioxidant, which can significantly improve the embryonic development potential of vitrified mouse MII oocytes. However, the underlying mechanism is still unknown. RNA sequencing indicated that the differentially expressed genes of …

Base Promoted Hydrogenation of N -Heteroarenes with Ammonia Borane and DMSO

Zhenkang Ai, Xinya Yuan, Guangbin Zhou, Guodong Zhang et autres

Herein, we report a sodium tert -butoxide-promoted reduction of N -heteroarenes using ammonia borane and dimethyl sulfoxide (DMSO) under mild reaction conditions. This method demonstrates broad functional group compatibility across diverse N -heteroarene substrates. Notably, substituting DMSO with deuterated DMSO- d 6 …

Decoding the Molecular Landscape of Prepubertal Oocyte Maturation: GTPBP4 as a Key Driver of In Vitro Developmental Competence

Jianpeng Qin, Yaozong Wei, Ao Ning, Wenqi Hu et autres

The intricate mechanisms driving oocyte maturation remain only partially understood, especially within the domains of domestic animal reproduction and translational medicine. In the case of prepubertal girls, the clinical challenge is especially pronounced, as ovarian tissue cryopreservation-though promising-remains an experimental technique necessitating …

Abnormalities in mitochondrial energy metabolism induced by cryopreservation negatively affect goat sperm motility

Shengqin Zang, Xiangyi Chen, Bo Pan, Ao Ning et autres

The motility of sperm decreases following cryopreservation, which is closely associated with mitochondrial function. However, the alterations in mitochondrial metabolism after sperm freezing in goats remain unclear. This experiment aimed to investigate the impact of ultra-low temperature freezing on goat sperm’s mitochondrial …

Oxidative Stress and Antioxidation in Testicular Leydig: Implications for Male Fertility

Ming Zhang, Yujun Tang, Hao Li, Guangbin Zhou et autres

Leydig cells, pivotal for male fertility, undergo significant oxidative stress due to their proximity to macrophages and reactive oxygen species (ROS) generated by extracellular structures. This stress disrupts Leydig cell function, impairing steroidogenesis and spermatogenesis, ultimately leading to male infertility. Oxidative stress …

Integrated ultrasensitive metabolomics and single-cell transcriptomics identify crucial regulators of sheep oocyte maturation and early embryo development in vitro

Bo Pan, Jianpeng Qin, Kunlin Du, Luyao Zhang et autres

INTRODUCTION: Developmental competence of oocytes matured in vitro is limited due to a lack of complete understanding of metabolism and metabolic gene expression during oocyte maturation and embryo development. Conventional metabolic analysis requires a large number of samples and is not efficiently …

The walnut-derived peptide TW-7 improves mouse parthenogenetic embryo development of vitrified MII oocytes potentially by promoting histone lactylation

Yaozong Wei, Bo Pan, Jianpeng Qin, Beijia Cao et autres

BACKGROUND: Previous studies have shown that the vitrification of metaphase II (MII) oocytes significantly represses their developmental potential. Abnormally increased oxidative stress is the probable factor; however, the underlying mechanism remains unclear. The walnut-derived peptide TW-7 was initially isolated and purified from …

Development of a Cobalt Catalyst from ZIF‐67 and Application in the Hydrogenation of N‐Heteroarenes

Xinya Yuan, Guangbin Zhou, Tianyi Zhou, Pan Gao et autres

Abstract Hydrogenation of N‐heteroarenes to saturated N‐heterocycles is an important reaction in organic synthesis. Hydrogen is a green reducing reagent and has been widely applied in industrial production. The development of an appropriate catalyst to realize hydrogenation at low pressure and temperature …
