Filter-Less Color-Selective Photodetector Derived from Integration of Parallel Perovskite Photoelectric Response Units.

Color-selective photodetectors (PDs) play an indispensable role in spectral recognition, image sensing, and other fields. Nevertheless, complex filters and delicate optical paths in such devices significantly increase their complexity and size, which subsequently impede their integration in smart optoelectronic chips for universal applications. This work demonstrates the successful fabrication of filter-less color-selective perovskite PDs by integrating three perovskite units with different photoresponse on a single chip.

Recent advances in single-cell genomics are improving our understanding of the molecular mechanisms of AMD. However, the pathophysiology of this multifactorial disease is complicated and still an ongoing challenge.

Transcriptomic and Metabolomic Changes Reveal the Immunomodulatory Function of Casein Phosphopeptide-Selenium Chelate in Beagle Dogs.

Casein phosphopeptide-selenium chelate (CPP-Se) is an organic compound produced by the chelation of casein phosphopeptide with selenium. This compound showed the ability to modulate canine immune response in our previous study; but its effect on the peripheral blood transcriptome and serum metabolome was unknown. This study aims to reveal the potential mechanism behind the immunomodulatory function of CPP-Se.

The ovarian-related effects of polystyrene nanoplastics on human ovarian granulosa cells and female mice.

Nanoplastics (NPs) have recently emerged in the context of global plastic pollution. They may be more toxic than macroplastics litter and microplastic fragments due to its abundances, tiny sizes, and cellular accessibility. The female reproductive toxicity of NPs has been widely documented for aquatic animals, but their effects and underlying mechanisms remain poorly understood in mammals.

Improved Dual-Polarity Response via Pyro-phototronic Effect for Filterless Visible Light Communication.

Dual-polarity response photodetectors (PDs) take full advantage of the directivity of the photocurrent to identify optical information. The dual-polarity signal ratio, a key parameter that represents the equilibrium degree of responses to different lights, is proposed for the first time. The synchronous enhancement of dual-polarity photocurrents and the amelioration of the dual-polarity signal ratio are beneficial to the practical applications.

RNAsmc: A integrated tool for comparing RNA secondary structure and evaluating allosteric effects.

RNA structure plays a crucial role in gene regulation, in RNA stability and the essential biological processes. RNA secondary structure (RSS) motifs are the basic building blocks for investigating the biological mechanisms of structure.

Effects of Casein Phosphopeptide-Selenium Complex on the Immune Functions in Beagle Dogs.

The health of pets is becoming a growing concern for the pet industry and its owners. Immunity is one of the foundational supports for health, thus developing a functional bioactive substance that can boost pets' immunity is essential. Many studies have shown that casein phosphopeptide (CPP) and selenium (Se) can individually regulate immunity in many species, but there has been no reported research on the immunomodulatory function of casein phosphopeptide-selenium complex (CPP-Se).

Transcriptome-wide mA profiling reveals mRNA post-transcriptional modification of boar sperm during cryopreservation.

Background: Cryopreservation induces transcriptomic and epigenetic modifications that strongly impairs sperm quality and function, and thus decrease reproductive performance. N-methyladenosine (mA) RNA methylation varies in response to stress and has been implicated in multiple important biological processes, including post-transcriptional fate of mRNA, metabolism, and apoptosis. This study aimed to explore whether cryopreservation induces mA modification of mRNAs associated with sperm energy metabolism, cryoinjuries, and freezability.
