Article Synopsis
  • The study investigates the effectiveness of the modified furosemide responsiveness index (mFRI) as a biomarker for predicting the progression of acute kidney injury (AKI) and adverse outcomes in patients who experienced mild to moderate AKI after cardiac surgery.
  • It compared mFRI with other renal biomarkers and cytokines, finding that mFRI performed equally or better in predicting AKI progression and other serious outcomes like hospital mortality and renal replacement therapy (RRT).
  • The research suggests that using a combination of mFRI and urinary injury biomarkers improves the prediction of adverse renal outcomes more effectively than using either biomarker alone.

Discectomy is the surgical standard of care to relieve low back pain caused by intervertebral disc (IVD) herniation. However, there remains annulus fibrosus (AF) defect and nucleus pulposus (NP) degeneration, which often result in recurrent herniation (re-herniation). Herein, we develop a polyphenol-modified waterborne polyurethane bioadhesives (PPU-glues) to promote therapy prognosis after discectomy.

Oxygen uptake (V˙O2) is an essential metric for evaluating cardiopulmonary health and athletic performance, which can barely be directly measured. Heart rate (HR) is a prominent physiological indicator correlated with V˙O2 and is often used for indirect V˙O2 prediction. This study investigates the impact of HR placement on V˙O2 prediction accuracy by analyzing HR data combined with the respiratory rate (RESP) and minute ventilation (V˙E) from three anatomical locations: the chest; arm; and wrist.

Inspired by tug-of-war, a game-changing bone-tendon fixation paradigm was developed. Specifically, injectable citrate-based bioactive self-expansive and planar-fixing screw (iCSP-Scr) consisting of reactive isocyanate (NCO) terminalized citrate-based polyurethane, proanthocyanidin modified hydroxyapatite (HAp) and water (with/without porogen) was developed and administrated in the bone-tendon gap. Instead of the "point to point" tendon fixation by traditional interface screws, along with the moisture-induced crosslinking and expansion of iCSP-Scr within the confined space of the irregularly shaped bone-tendon gap, the tendon graft was evenly squeezed into the bone tunnel in a "surface to surface" manner to realize strong and stable bone-tendon fixation via physical expansion, mechanical interlocking and chemical bonding (between -NCO and the -NH, -SH groups on bone matrix).

Article Synopsis
  • - Nitrogen (N) fertilizers, especially at high levels, can enhance the ability of caterpillar larvae (Spodoptera litura) to withstand insecticides by boosting their detoxification enzymes and thickening their cuticles.
  • - Bioassays and genetic analyses revealed that larvae consuming maize with high N levels showed increased tolerance to multiple pesticides, alongside elevated expression of certain genes related to detoxification and cuticle development.
  • - This increase in pesticide tolerance due to high N fertilizer usage might lead to more frequent and intensive use of chemical insecticides, raising concerns about pest management practices.

The current disease risk prediction model with many parameters is complex to run smoothly on mobile terminals such as tablets and mobile phones in imaginative elderly care application scenarios. In order to further reduce the number of parameters in the model and enable the disease risk prediction model to run smoothly on mobile terminals, we designed a model called Motico (An Attention Mechanism Network Model for Image Data Classification). During the implementation of the Motico model, in order to protect image features, we designed an image data preprocessing method and an attention mechanism network model for image data classification.

Designing a multifunctional electrocatalyst to produce H from water, urea, urine, and wastewater, is highly desirable yet challenging because it demands precise Fermi-engineering to realize stronger π-donation from O 2p to electron(e)-deficient metal (t) d-orbitals. Here a Sr-induced phase transformed β-FeOOH/α-Ni(OH) catalyst anchored on Ni-foam (designated as pt-NFS) is introduced, where Sr produces plenteous Fe (Fe → Fe) to modulate Fermi level and e-transfer from e-rich Ni(t)-orbitals to e-deficient Fe(t)-orbitals, via strong π-donation from the π-symmetry lone-pair of O bridge. pt-NFS utilizes Fe-sites near the Sr-atom to break the H─O─H bonds and weakens the adsorption of *O while strengthening that of *OOH, toward hydrogen evolution reaction (HER) and oxygen evolution reaction (OER), respectively.
