A fibrin gel-loaded Gouqi-derived nanovesicle (GqDNV) repairs the heart after myocardial infarction by inhibiting p38 MAPK/NF-κB p65 pathway.

The restoration of cardiac function post-myocardial infarction (MI) remains a significant clinical challenge. Emerging evidence indicates that Goji berries ("Gouqi" in Chinese) and their extracts exhibit substantial cardioprotective properties. Here, we introduce fibrin gel-loaded Gouqi-derived nanovesicles (GqDNVs-gel) as a delivery system targeted at the infarcted myocardium.

Gouqi-derived Nanovesicles (GqDNVs) promoted MC3T3-E1 cells proliferation and improve fracture healing.

Protective effects of bone marrow mesenchymal stem cell-derived exosomes loaded cerium dioxide nanoparticle against deoxynivalenol-induced liver damage.

Background: Deoxynivalenol (DON), a mycotoxin produced by Fusarium species, posed significant threats to food safety and human health due to its widespread prevalence and detrimental effects. Upon exposure, the liver, which played a crucial role in detoxifying DON, experienced depleted antioxidant levels and heightened inflammatory responses. Bone marrow mesenchymal stem cell (BMSC)-derived exosomes (BMSC-exos) exhibited therapeutic potential by promoting cellular repair and delivering bioactive substances, such as cerium dioxide nanoparticles (CeO₂ NPs), which are recognized for their ability to mitigate oxidative stress and inflammation.

Competing endogenous RNA networks were associated with fat accumulation in skeletal muscle of aged male mice.

Muscle aging contributed to morbidity and mortality in the elderly adults by leading to severe outcomes such as frailty, falls and fractures. Post-transcriptional regulation especially competing endogenous RNA (ceRNA) mechanism may modulate the process of skeletal muscle aging. RNA-seq was performed in quadriceps of 6-month-old (adult) and 22-month-old (aged) male mice to identify differentially expressed ncRNAs and mRNAs and further construct ceRNA networks.

Construction of 5-Fluorouracil and Gallium Corrole Conjugates for Enhanced Photodynamic Therapy.

Molecular hybridization is a well-established strategy for developing new drugs. In the pursuit of promising photosensitizers (PSs) with enhanced photodynamic therapy (PDT) efficiency, a series of novel 5-fluorouracil (5FU) gallium corrole conjugates () were designed and synthesized by hybridizing a chemotherapeutic drug and PSs. Their photodynamic antitumor activity was also evaluated.

Gouqi-derived nanovesicles (GqDNVs) inhibited dexamethasone-induced muscle atrophy associating with AMPK/SIRT1/PGC1α signaling pathway.

With the increasing trend of global aging, sarcopenia has become a significant public health issue. Goji berry, also known as "Gou qi zi" in China, is a traditional Chinese herb that can enhance the structure and function of muscles and bones. Otherwise, previous excellent publications illustrated that plant-derived exosome-like nanoparticles can exert good bioactive functions in different aging or disease models.

Structures and growth pathways of AuCl (n ≤ 7) cluster anions.

Gold chloride clusters play an important role in catalysis and materials chemistry. Due to the diversity of their species and isomers, there is still a dearth of structural studies at the molecular level. In this work, anions of AuCl and AuCl (n = 2-4) clusters were obtained by laser desorption/ionization mass spectrometry (LDI MS), and the most stable isomers of AuCl were determined after a thorough search and optimization at the TPSSh/aug-cc-pVTZ/ECP60MDF level.

Effects of Timing and Types of Protein Supplementation on Improving Muscle Mass, Strength, and Physical Performance in Adults Undergoing Resistance Training: A Network Meta-Analysis.

Precise protein supplementation strategies for muscle improvement are still lacking. The timing or type of protein supplementation has been debated as a window of opportunity to improve muscle mass, strength, and physical performance. We conducted a network meta-analysis of randomized controlled trials with protein supplements and resistance training.

Structural Characterization of the Metalized Radical Cations of Adenosine ([Ade+Li-H] and [Ade+Na-H]) by Infrared Multiphoton Dissociation Spectroscopy and Theoretical Studies.

Nucleoside radicals are key intermediates in the process of DNA damage, and alkali metal ions are a common group of ions in living organisms. However, so far, there has been a significant lack of research on the structural effects of alkali metal ions on nucleoside free radicals. In this study, we report a new method for generating metalized nucleoside radical cations in the gas phase.

Deoxynivalenol Exposure Induced Colon Damage in Mice Independent of the Gut Microbiota.

Scope: To investigate whether deoxynivalenol (DON) can induce intestinal damage through gut microbiota in mice.

Methods And Results: Mice are orally administered DON (1 mg kg bw day ) for 4 weeks, and then recipient mice receive fecal microbiota transplantation (FMT) from DON-exposed mice after antibiotic treatment. Furthermore, the mice are orally treated with DON (1 mg kg bw day ) for 4 weeks after antibiotic treatment.

Human milk extracellular vesicles enhance muscle growth and physical performance of immature mice associating with Akt/mTOR/p70s6k signaling pathway.

Extracellular vesicles (EVs) play an important role in human and bovine milk composition. According to excellent published studies, it also exerts various functions in the gut, bone, or immune system. However, the effects of milk-derived EVs on skeletal muscle growth and performance have yet to be fully explored.

The circadian rhythm gene Bmal1 ameliorates acute deoxynivalenol-induced liver damage.

Deoxynivalenol (DON) is widely emerging in various grain crops, milk, and wine products, which can trigger different toxic effects on humans and animals by inhalation or ingestion. It also imposes a considerable financial loss on the agriculture and food industry each year. Previous studies have reported acute and chronic toxicity of DON in liver, and liver is not only the main detoxification organ for DON but also the circadian clock oscillator directly or indirectly regulates critical physiologically hepatic functions under different physiological and pathological conditions.

A novel method for photon unfolding spectroscopy of protein ions in the gas phase.

In this study, a new experimental method for photon unfolding spectroscopy of protein ions based on a Fourier transform ion cyclotron resonance (FT ICR) mass spectrometer was developed. The method of short-time Fourier transform has been applied here to obtain decay curves of target ions trapped in the cell of the FT ICR mass spectrometer. Based on the decay constants, the collision cross sections (CCSs) of target ions were calculated using the energetic hard-sphere model.

Accurate assessment of parabens exposure in healthy Chinese female adults: Findings from a multi-pathway exposure assessment coupled with intervention study.

Exposure of humans to parabens is widespread and urinary parabens are widely used as exposure biomarkers. However, are the levels of these chemicals suitable to assess exposure to parabens? We conducted an intervention study by controlling the use of personal care products (PCPs) to explore the exposure of parabens. Ten female participants were recruited who were treated with different types of PCPs during the 18-day study period.
