LC-MS/MS Analyzing Praziquantel and 4-Hydroxypraziquantel Enantiomers in Black Goat Plasma and Mechanism of Stereoselective Pharmacokinetics.

Praziquantel (PZQ) is the most effective treatment for schistosomiasis, commonly administered as a racemic mixture of the two enantiomers. Despite many reports on the pharmacokinetics of PZQ, the stereoselective pharmacokinetics of PZQ and its major metabolite 4-hydroxypraziquantel (4-OH-PZQ) remain poorly understood in goats. In this study, the chiral LC-MS/MS method was further optimized for separating and quantifying PZQ, trans-4-OH-PZQ, and cis-4-OH-PZQ and their enantiomers and then applied for the molecular pharmacokinetics of three analytes in black goat plasma.

Theoretical and Experimental Research on the Short-Range Structure in Gallium Melts Based on the Wulff Cluster Model.

In this paper, the short-range ordering structures of Ga melts has been investigated using the Wulff cluster model (WCM). The structures with a Wulff shape outside and crystal symmetry inside have been derived as the equivalent system to describe the short-range-order (SRO) distribution of the Ga melts. It is observed that the simulated HTXRD patterns of the Ga WCM are in excellent agreement with the experimental data at various temperatures (523 K, 623 K, and 723 K).

Radiative Warming Glass for High-Latitude Cold Regions.

Traditional window glazing, with inherently adverse energy-efficient optical properties, leads to colossal energy losses. Energy-saving glass requires a customized optical design for different climate zones. Compared with the widely researched radiative cooling technology which is preferable to be used in low-altitude hot regions; conversely in high-latitude cold regions, high solar transmittance (T) and low mid-infrared thermal emissivity (ε) are the key characteristics of high-performance radiative warming window glass, while the current low-emissivity (low-e) glass is far from ideal.

AENK ameliorates cognitive impairment and prevents Tau hyperphosphorylation through inhibiting AEP-mediated cleavage of SET in rats with ischemic stroke.

Brain damage induced by ischemia promotes the development of cognitive dysfunction, thus increasing the risk of dementia such as Alzheimer's disease (AD). Studies indicate that cellular acidification-triggered activation of asparagine endopeptidase (AEP) plays a key role in ischemic brain injury, through multiple molecular pathways, including cleavage of its substrates such as SET (inhibitor 2 of PP2A, I ) and Tau. However, whether direct targeting AEP can effectively prevent post-stroke cognitive impairment (PSCI) remains unanswered.

Ultrasound nanobubble-based combinational strategies of loaded miR-107-3p and CD133 Ab for anti-PD-L1 and anti-hepatocellular cancer stem cells.

Background: CD133 is regarded as a marker and target for cancer stem cells (CSCs) in various types of tumors, including hepatocellular carcinoma (HCC). The expressions of CD133 and programmed cell death ligand 1 (PD-L1) in CSCs exhibit a positive feedback regulatory effect. This effect promotes CSC proliferation and immune escape, ultimately leading to tumor progression and poor prognosis.

APOM Modulates the Glycolysis Process in Liver Cancer Cells by Controlling the Expression and Activity of HK2 via the Notch Pathway.

The metabolic pathway of aerobic glycolysis in tumor cells has garnered significant attention in tumor research because of its high activation in cancer cells. Previous research conducted by our team has demonstrated that Apolipoprotein M (APOM) exhibits potential as a factor against liver cancer. However, further investigations are needed to elucidate the precise approach and mechanism that are involved in this process.

R2R3-MYB transcription factors RrMYB12 and RrMYB111 regulate the accumulation of flavonols and anthocyanins.

Roses () are a famous flower with high ornamental and economic value. But the petals of roses are usually pink and purple, which restricted its application in garden settings. Flavonols and anthocyanins are crucial secondary metabolites related to flower pigmentation in plants.

Light-Directed Self-Powered Metal-Organic Framework Based Nanorobots for Deep Tumor Penetration.

Effective intratumoral distribution of anticancer agents with good tumor penetration is of great practical importance for oncotherapy. How to break the limitation of traditional passive drug delivery relying on blood circulatory system into solid tumors remains a challenge. Herein, a light-directed self-powered nanorobot based on zirconium-based porphyrin metal-organic framework (MOF) is reported for smart delivery of chemodrug and photosensitizer for deep tumor penetration.

Enhanced electro-catalysis for methanol oxidation reaction performance by edge defects of ordered mesoporous carbon.

Heteroatom-doped carbon materials are widely used to improve the electrocatalytic oxidation of methanol; however, the underlying mechanisms driving this enhancement remain poorly understood. A major challenge lies in developing non-doped carbon supports with tunable intrinsic defect types tailored for metal-based catalysts. In this study, we synthesize a series of ordered mesoporous carbon (OMC) supports with adjustable edge defect densities by varying roasting temperatures and employing a zinc (Zn) evaporation strategy to systematically investigate the impact of edge defects on methanol oxidation reaction (MOR) performance.

Expert consensus on sequential surgery following conversion therapy based on combination of immune checkpoint inhibitors and antiangiogenic targeted drugs for advanced hepatocellular carcinoma (2024 edition).

Up to half of hepatocellular carcinoma (HCC) cases are diagnosed at an advanced stage, for which effective treatment options are lacking, resulting in a poor prognosis. Over the past few years, the combination of immune checkpoint inhibitors and anti-angiogenic targeted therapy has proven highly efficacious in treating advanced HCC, significantly extending patients' survival and providing a potential for sequential curative surgery. After sequential curative hepatectomy or liver transplantation following conversion therapy, patients can receive long-term survival benefits.

Effects of synbiotics surpass probiotics alone in improving type 2 diabetes mellitus: A randomized, double-blind, placebo-controlled trial.

Background And Aims: Combining probiotics and prebiotics in synbiotics may present a synergistic approach to improve type 2 diabetes mellitus (T2DM); however, further evidence is required to establish the comparative efficacy of synbiotics versus probiotics. This study aimed to evaluate the effects of Bifidobacterium animalis subsp. lactis MN-Gup (MN-Gup) and a synbiotic mixture of MN-Gup and galactooligosaccharide (MN-Gup-GOS) on glycemic control in T2DM patients and explore possible mechanisms.

Extraction of short-chain fatty acid ethyl Ester in Baijiu using covalent organic framework-based magnetic nanoparticles: Theoretical screening and experimental validation.

Short-chain fatty acid ethyl esters (SFAEEs) are critical aroma compounds in Baijiu, and their wider concentration range can lead to differences in the quality grade of Baijiu. Efficiently designing an SFAEEs adsorbent before instrument analysis remains challenging. In this work, nine functionalized covalent organic frameworks (COFs) with different postmodification groups were designed for targeting SFAEEs.

Non-image-forming photoreceptors improve visual orientation selectivity and image perception.

It has long been a decades-old dogma that image perception is mediated solely by rods and cones, while intrinsically photosensitive retinal ganglion cells (ipRGCs) are responsible only for non-image-forming vision, such as circadian photoentrainment and pupillary light reflexes. Surprisingly, we discovered that ipRGC activation enhances the orientation selectivity of layer 2/3 neurons in the primary visual cortex (V1) of mice by both increasing preferred-orientation responses and narrowing tuning bandwidth. Mechanistically, we found that the tuning properties of V1 excitatory and inhibitory neurons are differentially influenced by ipRGC activation, leading to a reshaping of the excitatory/inhibitory balance that enhances visual cortical orientation selectivity.
