Active immunization with a novel recombinant GnRH vaccine inhibits reproductive function in male goats.

Gonadotropin-releasing hormone (GnRH) vaccines have been widely used to effectively inhibit gonadal development and reproductive function. To improve the immunogenicity of GnRH, we developed and evaluated the effects of GnRH6-kisspeptin-CRM197 immunization on the reproductive function in male goats. Thirty 3-month-old male goats (n = 30) were randomly assigned to control, surgical, and immunized groups.

Programming a bacterial biosensor for directed evolution of tryptophan hydroxylase via high-throughput droplet sorting.

The modification of tryptophan hydroxylase (TPH) for the biosynthesis of 5-hydroxytryptophan (5-HTP) has recently become a focus of research. In this study, we established a droplet-based ultrahigh-throughput microfluidic screening platform (DTSP) to improve the industrial properties of TPH, whereas a bacterial biosensor for L-tryptophan (L-Trp) detection was engineered to improve sensitivity. The promoter pJ23111 achieved a strong negative correlation between the L-Trp concentration and the fluorescence output of the biosensor.

Epigenomic Landscape of Human Cumulus Cells in Premature Ovarian Insufficiency Using Single-Base Resolution Methylome and Hydroxymethylome.

Premature ovarian insufficiency (POI) has recently been reported to be linked with epigenetic changes. Previous studies have focused on the regulation of individual genes associated with ovarian function through single-gene epigenetic variations; however, there is a deficiency in the comprehensive comprehension of the epigenetic profile for POI. Therefore, we conducted a multi-omics study integrating methylation, hydroxymethylation and transcriptome sequencing analyses in cumulus cells from women with POI and their matched controls.

Study on identification of diagnostic biomarkers in serum for papillary thyroid cancer in different iodine nutrition regions.

BackgroundAt present, there is a lack of efficient biomarkers for the diagnosis of thyroid cancer, and the influence of natural factors such as high iodine exposure on the expression of biomarkers remains unclear.MethodsSerum samples from papillary thyroid cancer (PTC) and non-cancer controls matched 1:1 in different iodine nutritional regions were analyzed metabolomically using an ultra-high performance liquid chromatography-Orbitrap Exploris mass spectrometry (UHPLC-OE-MS) platform. Then the data were randomly divided into training and test sets in a 1:1 ratio according to the different iodine nutritional regions and different PTC status.

A feasible approach to chromophores removal and color reduction in industrial lignin via deep eutectic solvent/isopropanol treatment.

The dark coloration of industrial lignin significantly limits its potential for applications in high-value products. This work reported a practical strategy for lignin color reduction through the synergistic treatment of acidic deep eutectic solvent and isopropanol (DES-IPA). The results showed that the DES-IPA treatment could effectively remove the p-coumarate units and methoxy groups in lignin.

Effect of electroacupuncture on metabolic alterations in the hippocampus and dorsal raphe nucleus of Wistar Kyoto rats.

Depression is underpinned by a complex pathogenesis that involves the hippocampus and dorsal raphe nucleus (DRN) of the central nervous system. Although electroacupuncture (EA) is proven to be safe and effective for alleviating depression symptoms and causes minimal side effects its underlying therapeutic mechanism remains unclear. In this study, we performed targeted metabolomics to identify metabolite alterations in the hippocampus and DRN of Wistar Kyoto (WKY) rats and elucidate the role and potential mechanism of action of EA.

Novel neonicotinoid insecticide cycloxaprid exhibits sublethal toxicity to honeybee (Apis mellifera L.) workers by disturbing olfactory sensitivity and energy metabolism.

The risk of neonicotinoid insecticides to honeybees is a global issue. Cycloxaprid (CYC) is a novel neonicotinoid insecticide with outstanding activities, good safety profiles, and no cross-resistance with other neonicotinoids. Information on the environmental risks of CYC is limited, especially its effects on honeybees.

Tailored Lead-Free KNN/BFO Perovskite Ferroelectric Film Heterostructures for Enhanced Electrofunctional Properties via Interface-Modulated Bilayer Design.

In this work, a bilayer lead-free perovskite ferroelectric structure was fabricated comprising a highly polar BiFeO (BFO) bottom layer and a less polar (KNa)NbO (KNN) top layer. The BFO sublayer, deposited via radio frequency magnetron sputtering without postgrowth annealing, not only exhibited enhanced crystallinity but also promoted superior microstructural properties in the sol-gel derived KNN overlayer, thereby ensuring excellent intrinsic electrical properties. Compared to the poorly crystallized single-layer KNN films directly synthesized on LNO-buffered (100)-Si substrate, the KNN layer in the bilayer structure demonstrated a strong (100) texture, along with a dense, homogeneous, fine-grained morphology.

Origin and cross-species transmission of bat coronaviruses in China.

Bats are presumed reservoirs of diverse coronaviruses (CoVs) including progenitors of Severe Acute Respiratory Syndrome (SARS)-CoV and SARS-CoV-2, the causative agent of COVID-19. However, the evolution and diversification of these coronaviruses remains poorly understood. Here we use a Bayesian statistical framework and a large sequence data set from bat-CoVs (including 589 novel CoV sequences) in China to study their macroevolution, cross-species transmission and dispersal.
