Electrochemical nitrate reduction (NORR) to ammonia presents a promising alternative strategy to the traditional Haber-Bosch process. However, the competitive hydrogen evolution reaction (HER) reduces the Faradaic efficiency toward ammonia, while the oxygen evolution reaction (OER) increases the energy consumption. This study designs IrCu alloy nanoparticles as a bifunctional catalyst to achieve efficient NORR and OER while suppressing the unwanted HER.

Owing to autofluorescence-free feature, persistent luminescent (PersL) nanoparticles (PLNPs) become potential materials for tumor surgical navigation. However, it is still challenging to enhance PersL intensity, contrast ratio, and imaging stability so as to meet clinical demand and avoid missed detection of microlesions. Herein, integrating a tumor microenvironment (TME)-responsive strategy, sensitization enhancement, and internal-standard ratiometric method, a dual-mode PersL imaging strategy is proposed: After loading pH-responsive fluorescent molecule Rh-ADM on PLNPs ZnGaO:Cr,Mn (ZGCM-Rh8), the fluorescence resonance energy transfer (FRET) pathways between Cr and Rh-ADM, as well as Mn and Rh-ADM, could sensitize the NIR PersL emitted by Cr and quench the green PersL from Mn at acidic TME, respectively.

Photodynamic and photothermal therapy (PDT and PTT) have been widely used in tumor treatment researches owe to its advantages of spatiotemporal controlliability and non-invasiveness. Combining two phototherapy strategies together and/or with chemodynamic therapy (CDT) could achieve better therapeutic efficiency, but the resulting inconvenient dual-laser irradiation and the potential skin toxicity limit its development. Moreover, the lack of tumor-specificity causes side-effects to normal tissues.

Developing resistance to cancer treatments is a major challenge, often leading to disease recurrence and metastasis. Understanding the underlying mechanisms of therapeutic resistance is critical for developing effective strategies. O-GlcNAcylation, a post-translational modification that adds GlcNAc from the donor UDP-GlcNAc to serine and threonine residues of proteins, plays a crucial role in regulating protein function and cellular signaling, which are frequently dysregulated in cancer.

Introduction: Ventilator-associated pneumonia (VAP) causes increased time of mechanical ventilation (MV), prolonged intensive care unit (ICU) stay, and a higher mortality risk. The systematic review and meta-analysis aimed to compare the efficacies between fiberoptic bronchoscopy (FOB) and general sputum suction for the prevention of VAP in patients with invasive MV.

Methodology: Relevant randomized controlled trials (RCTs) were obtained via a search of PubMed, Embase, Cochrane Library, Wanfang, and CNKI databases.

Strong evidence indicates that environmental stressors are the risk factors for male testosterone deficiency (TD). However, the mechanisms of environmental stress-induced TD remain unclear. Based on our all-cause male reproductive cohort, we found that serum ferrous iron (Fe⁺) levels were elevated in TD donors.

Article Synopsis
  • - Infertility linked to lipopolysaccharide (LPS) exposure from infections is threatening male fertility, influencing blood-testis barrier (BTB) function essential for sperm production and overall male reproductive health.
  • - LPS treatment in mice was found to damage BTB by decreasing related protein levels, increasing biotin penetration, and harming seminiferous tubules, with the testicular macrophage M1 polarization being a major factor in this damage.
  • - Interestingly, low-dose LPS exposure can protect against these harmful effects by regulating HDAC5 levels and reducing testicular macrophage M1 polarization, suggesting potential therapeutic strategies for improving male fertility affected by LPS.

Surgical resection remains the main treatment for malignant tumors. Image-guided surgery aims to remove tumor tissue completely while preserving normal tissue, thereby reducing tumor recurrence rates and injury. However, challenges like tissue autofluorescence, limited probe penetration and low contrast restrict its use.

  • The study investigates the combined effects of phthalate esters (PAEs) on human health, using an in vitro model with human macrophages to assess toxicity and mechanisms.
  • Findings indicate that different PAEs have varying impacts on M2 macrophage polarization, with mono(2-ethylhexyl) phthalate (MEHP) being the most effective at suppressing this polarization.
  • In vivo results showed that a mixture of PAEs led to significant liver health issues, supporting the need for further analysis of the health risks associated with combined exposure to these compounds.

Photovoltaic (PV) heating is a promising technology for achieving fossil fuel-free heating and carbon neutrality in the building sector. Cost-effective energy storage plays a critical role in PV heating to solve the temporal mismatch between supply and demand. Herein, we propose the concept of using a building envelope as an active energy-storage device for a PV heating system, thus transforming the building envelope into a thermal battery.

Cadmium (Cd) is a widely distributed typical environmental pollutant and one of the most toxic heavy metals. It is well-known that environmental Cd causes testicular damage by inducing classic types of cell death such as cell apoptosis and necrosis. However, as a new type of cell death, the role and mechanism of pyroptosis in Cd-induced testicular injury remain unclear.

Low testosterone (T) levels are associated with many common diseases, such as obesity, male infertility, depression, and cardiovascular disease. It is well known that environmental cadmium (Cd) exposure can induce T decline, but the exact mechanism remains unclear. We established a murine model in which Cd exposure induced testicular T decline.

  • The study aims to evaluate the effectiveness of drug-coated balloons (DCB) compared to drug-eluting stents (DES) in patients undergoing percutaneous coronary interventions (PCI) for chronic total occlusions (CTO), highlighting that DCB may reduce the need for repeat procedures.
  • A total of 157 patients were analyzed, with 112 receiving DCB and 45 treated with DES; results showed that DCB patients had significantly lower rates of major adverse cardiac and cerebrovascular events (MACCE) at 12 months following the procedure.
  • The research concludes that DCB use in CTO cases may be safer and improve outcomes by limiting stent length, which is linked to better PCI results.
