UV-B irradiation promotes anthocyanin biosynthesis in the leaves of .

Anthocyanins are the most valuable pigments in (). Although ultraviolet-B (UV-B) irradiation is a key environmental factor influencing anthocyanin biosynthesis in , the deep molecular mechanism remains unclear. Herein, we examined the changes in the total anthocyanin content and transcriptomic characteristics of leaves following UV-B irradiation treatment.

[The impact of anxiety levels in male soldiers with infertility on stress coping strategies and the quality of fertility life].

Objective: To explore and analyze the correlation between anxiety levels, coping strategies, and fertility quality of life in male soldiers with infertility.

Methods: A questionnaire survey was conducted on 480 male soldiers with infertility who visited the Reproductive Medicine Department of the Eastern Theater Command General Hospital from June 2022 to February 2023, analyze the impact of anxiety levels on stress coping strategies and fertility quality of life in male officers and soldiers with infertility.

Results: Self evaluation scale score is (43.

Characterization and phylogenetic analysis of the complete chloroplast genome of (Liliaceae).

The chloroplast genome and evolutionary relationship analysis of could provide fundamental genetic reference for its molecular breeding and biological research. The complete chloroplast genome of was sequenced and reported here. The genome was 152,050 bp in length, containing a pair of inverted repeated regions (26,330 bp) which were separated by a large single copy region of 82,184 bp, and a small single copy region of 17,206 bp.

Role of peroxiredoxin 2 in H2O2‑induced oxidative stress of primary Leydig cells.

Late‑onset hypogonadism is defined as a condition caused by a decline in the levels of testosterone with aging. One of the major factors contributing to the low levels of testosterone is the accumulation of reactive oxygen species (ROS) in Leydig cells during the ageing process. Peroxiredoxin 2 (Prdx2), a member of the peroxiredoxin family, is an antioxidant protein, the predominant function of which is to neutralize ROS.

Backbone and side-chain NMR assignments for the bromodomain of mouse BAZ1A (ACF1).

BAZ1A, a non-catalytic subunit of the chromatin remodeler complexes ACF and CHRAC, is thought to modulate the ATPase's activity of the complexes and participate in gene transcription, DNA damage checkpoint and double-strand break repair. Recently, the essential role of BAZ1A in mouse male fertility has also been reported. BAZ1A contains one C-terminal bromodomain, which specifically recognizes acetylation of lysine.

The Semen pH Affects Sperm Motility and Capacitation.

As the chemical environment of semen can have a profound effect on sperm quality, we examined the effect of pH on the motility, viability and capacitation of human sperm. The sperm in this study was collected from healthy males to avoid interference from other factors. The spermatozoa cultured in sperm nutrition solution at pH 5.

Long-range surface plasmon polariton waveguides embedded in fluorinated polymer.

Low-attenuation waveguides based on the propagation of long-range surface plasmon polaritons (LRSPPs) along thin Au stripes embedded in low absorption perfluorocyclobutane (PFCB) polymer are presented. A new low in propagation loss of <2.0 dB/cm was achieved for a 4 microm wide waveguide by optimizing the cladding material and fabrication process.
