Chimeric antigen receptor-T cells targeting AFP-GPC3 mediate increased antitumor efficacy in hepatocellular carcinoma.

Background And Study Aims: As a novel immunotherapy, chimeric antigen receptor T (CAR-T) cell technology is successful in treating hematologic malignancies, and exhibits potential benefits in partial solid tumors. Therapies targeting one antigen have some weaknesses, and dual-targeted CAR-T cells may be a better option. Alpha-fetoprotein (AFP) and glypican-3 (GPC3) are both highly expressed in hepatocellular carcinoma (HCC) and serve as important markers.

Exploration of the Relationship between Polycystic Ovary Syndrome and Recurrent Pregnancy Loss Based on Bioinformatics.

Background: Recurrent Pregnancy Loss (RPL) and Polycystic Ovary Syndrome (PCOS) are both common diseases involving women of childbearing age, and their pathogenesis is still not sufficiently known.

Objective: This study aimed to explore the relationship between RPL and PCOS in bioinformatics.

Methods: Two expression chips, GSE86241 (obtained from 8 PCOS patients and 9 healthy controls) and GSE73025 (obtained from 5 RPL patients and 5 healthy controls), were downloaded from the Gene Expression Omnibus (GEO) database.

Network Pharmacology, Molecular Docking, and Experimental Validation on Guiluoshi Anzang Decoction Against Premature Ovarian Insufficiency.

Background And Objectives: Premature Ovarian Insufficiency (POI) is a disease suffered by women under the age of 40 when ovarian function has declined, seriously affecting both the physical and mental health of women. Guiluoshi Anzang decoction (GLSAZD) has been used for a long time and has a unique therapeutic effect on improving ovarian function. This study aims to investigate the mechanism of GLSAZD in treating POI through network pharmacology, molecular docking, and experimental verification.

Nanotoxicity of tungsten trioxide nanosheets containing oxygen vacancy to human umbilical vein endothelial cells.

Because of the excellent performance in photochemistry, WO is increasingly applied in the field of biology and medicine. However, little is known about the mechanism of WO cytotoxicity. In this work, WO nanosheets with oxygen vacancy are synthesized by solvothermal method, then characterized and added to culture medium of human umbilical vein endothelial cells (HUVECs) with different concentrations.

Surface Oxygen Deficiency Enabled Spontaneous Antiprotein Fouling in WO Nanosheets for Biosensing in Biological Fluids.

Biofouling deteriorates the performance of sensors operated in biofluids. Protein adsorption is believed to be the first step of biofouling, which also reduces biocompatibility by further inducing cell adhesion, platelet activation, and even inflammation. Current studies of antifouling coatings are focused on polymers and hydrogels, which have succeeded in remaining resistant to protein adsorption, but their application on sensor electrodes is limited due to low conductivity and biocompatibility.

Chromosome-level genome assembly and functional characterization of terpene synthases provide insights into the volatile terpenoid biosynthesis of Wurfbainia villosa.

Wurfbainia villosa is a well-known medicinal and edible plant that is widely cultivated in the Lingnan region of China. Its dried fruits (called Fructus Amomi) are broadly used in traditional Chinese medicine for curing gastrointestinal diseases and are rich in volatile terpenoids. Here, we report a high-quality chromosome-level genome assembly of W.

Research on germplasm diversity of Amomum villosum. Lour in genuine producing area.

Background: Genuine Chinese medicine is produced from medicinal plant cultivated in a specific region and is of better quality and efficacy, more consistently qualified and famous than that from the same medicinal plant cultivated in other regions. The cultivating region of genuine medicinal plant is known as the genuine producing area. Yangchun City, which is in Guangdong Province of China, is a genuine producing area for the famous Chinese medicine Amomi Fructus (also called Sharen).

Tanshinone IIA enhances the ovarian reserve and attenuates ovarian oxidative stress in aged mice.

Background: Tanshinone IIA (TSA), a major lipophilic component extracted from the roots of Salvia miltiorrhiza Bunge, has been widely used in China for its various biological activities. However, its effect on ovarian reserve in aged mice was not studied elsewhere.

Objectives: This study aimed to explore the effect of TSA on the ovarian reserve of aged mice as well as young mice.

Point-of-care COPD diagnostics: biomarkers, sampling, paper-based analytical devices, and perspectives.

Chronic obstructive pulmonary disease (COPD) has become the third leading cause of global death. Insufficiency in early diagnosis and treatment of COPD, especially COPD exacerbations, leads to a tremendous economic burden and medical costs. A cost-effective and timely prevention requires decentralized point-of-care diagnostics at patients' residences at affordable prices.

Mitigating hook effect in one-step quantitative sandwich lateral flow assay by timed conjugate release.

Sandwich lateral flow assay (LFA) is one of the most successfully commercialized paper-based biosensors, which offers a rapid, low-cost, one-step assay. Despite its advantages, conventional sandwich LFA is fundamentally limited by the high-dose "hook" effect-a phenomenon that occurs at very high analyte concentrations and results in false-negative results. In this paper, we present a novel strategy of automatic timed detection antibody release to mitigate the hook effect in sandwich LFA without additional manual steps.

Research on the reproductive biological characteristics of Amomum villosum Lour. and Amomum longiligulare T. L. Wu.

Objective: To explore the influence of biological characteristics on the yield of Amomum villosum Lour. and Amomum longiligulare T. L.

Exploring antimicrobial mechanism of essential oil of Amomum villosum Lour through metabolomics based on gas chromatography-mass spectrometry in methicillin-resistant Staphylococcus aureus.

Amomum villosum Lour (A. villosum Lour) has medicinal properties and has been widely used in China for many years. Herein we aimed to investigate the antibacterial mechanism and the metabolome variation caused by A.

[Study on ecological stereoscopic cultivation mode of Amomum villosum-Dimocarpus longan].

In order to set up a technical standard for planting Amomum villosum in wood forest in the future, we analyzed the relationship between the ecological factors and the yield of A. villosum planted in five Dimocarpus imocarpus longan wood forests and five miscellaneous wood forests in Yangchun city, to find out the dominant factors that affect the yield of A. villosum.

HDAC inhibitors suppress c-Jun/Fra-1-mediated proliferation through transcriptionally downregulating MKK7 and Raf1 in neuroblastoma cells.

Activator protein 1 (AP-1) is a transcriptional factor composed of the dimeric members of bZIP proteins, which are frequently deregulated in human cancer cells. In this study, we aimed to identify an oncogenic AP-1 dimer critical for the proliferation of neuroblastoma cells and to investigate whether histone deacetylase inhibitors (HDACIs), a new generation of anticancer agents, could target the AP-1 dimer. We report here that HDACIs including trichostatin A, suberoylanilidehydroxamic acid, valproic acid and M344 can transcriptionally suppress both c-Jun and Fra-1, preceding their inhibition of cell growth.

Synthesis of α,α-difluoromethylene alkynes by palladium-catalyzed gem-difluoropropargylation of aryl and alkenyl boron reagents.

gem-Difluoropropargyl bromides are versatile intermediates in organic synthesis, but have rarely been employed in transition-metal-catalyzed cross-coupling reactions. The first palladium-catalyzed gem-difluoropropargylation of organoboron reagents with gem-difluoropropargyl bromides is now reported. The reaction proceeds under mild reaction conditions with high regioselectivity; it features a broad substrate scope and excellent functional-group compatibility and thus provides an attractive approach for the synthesis of complex fluorinated molecules, in particular for drug discovery and development.

Nickel-catalyzed cross-coupling of functionalized difluoromethyl bromides and chlorides with aryl boronic acids: a general method for difluoroalkylated arenes.

Transition-metal-catalyzed difluoroalkylation of aromatics remains challenging despite the importance of difluoroalkylated arenes in medicinal chemistry. Herein, the first successful example of nickel-catalyzed difluoroalkylation of aryl boronic acids is described. The reaction allows access to a variety of functionalized difluoromethyl bromides and chlorides, and paves the way to highly cost-efficient synthesis of a wide range of difluoroalkylated arenes.
