The role of intravenous glutamine administration in critical care patients with acute kidney injury: a narrative review

引用

Emergency and Critical Care Medicine 2024年第3期4卷 117-125页

作者： jonny j. Larasati A.d. Ramadhani B.P. Hernowo B.A. Pasiak T.f. faculty of Medicine Universitas Prima Indonesia Medan Indonesia department of Internal Medicine Gatot Soebroto Central Army Hospital Dki Jakarta Indonesia faculty of Medicine of the jakarta Veteran National development University Dki Jakarta Indonesia faculty of Military Medicine Indonesia Defense University West Java Indonesia

The kidneys are complex organs responsible for waste removal and various regulatory functions. Critically ill patients often experience acute kidney injury (AKI). Although renal replacement therapy is used to manage AKI, nutritional therapy is crucial. Glutamine, an amino acid involved in cellular functions, has potential benefits when administered intravenously to critically ill patients. This administration is associated with reduced mortality rates, infectious complications, and hospitalization duration. However, its use in patients with AKI remains controversial. Glutamine is used by various organs, including the kidneys, and its metabolism affects several important pathways. Intravenous glutamine supplementation at specific doses can improve blood marker levels and restore plasma glutamine concentrations. Moreover, this supplementation reduces infections, enhances immune responses, decreases disease severity scores, and reduces complications in critically ill patients. However, caution is advised in patients with multiple organ failure, particularly AKI, as high doses of glutamine may increase mortality rates. Hyperglutaminemia can have adverse effects. Monitoring and appropriate dosing can help to mitigate these risks. Kidneys rely on glutamine for various essential functions. Thus, the use of intravenous glutamine in critically ill patients with AKI remains controversial. despite its potential benefits in terms of infection reduction, immunomodulation, and improved outcomes, careful consideration of the patient's condition, dosage, and treatment duration is necessary. further research is needed to establish optimal guidelines for glutamine administration in this patient population. © Wolters Kluwer Health, Inc.

A multi-shot target wheel assembly for high-repetition-rate, laser-driven proton acceleration

High Power Laser Science and Engineering 2024年第02期 91-98页

作者： j.Pe?as A.Bembibre d.Cortina-Gil L.martín A.Reija C.Ruiz M.Seimetz A.Alejo j.Benlliure Instituto Galego de física de Altas Enerxías Universidade de Santiago de Compostela Laboratorio Láser de Aceleración y Aplicaciones RIAIDT Universidade de Santiago de Compostela Instituto Universitario de física fundamental y matemáticas y dpto.de didáctica de la matemática y de las Ciencias Experimentales Universidad de Salamanca Instituto de Instrumentación para Imagen Molecular (I3M) CSIC-Universitat Politècnica de València

A multi-shot target assembly and automatic alignment procedure for laser–plasma proton acceleration at high repetition rate are introduced. The assembly is based on a multi-target rotating wheel capable of hosting more than 5000 targets,mounted on a 3d motorized stage to allow rapid replenishment and alignment of the target material between laser irradiations. The automatic alignment procedure consists of a detailed mapping of the impact positions at the target surface prior to the irradiation that ensures stable operation of the target, which alongside the purpose-built design of the target wheel, enables operation at rates up to 10 Hz. Stable and continuous laser-driven proton acceleration at 10 Hz is demonstrated, with observed cut-off energy stability about 15%.

Engineering vascularised organoid-on-a-chip: strategies, advances and future perspectives

引用

Biomaterials Translational 2024年第1期5卷 21-32页

作者： Li Z. Yu d. Zhou C. Wang f. Lu K. Liu Y. Xu j. Xuan L. Wang X. department of Micro/Nano Electronics School of Electronic Information and Electrical Engineering Shanghai Jiao Tong University Shanghai China Institute of Medical Robotics Shanghai Jiao Tong University Shanghai China National Key Laboratory of Advanced Micro and Nano manufacture Technology Shanghai Jiao Tong University Shanghai China National Center for Translational Medicine (Shanghai) SHU Branch Shanghai University Shanghai China

In recent years, advances in microfabrication technology and tissue engineering have propelled the development of a novel drug screening and disease modelling platform known as organoid-on-a-chip. This platform integrates organoids and organ-on-a-chip technologies, emerging as a promising approach for in vitro modelling of human organ physiology. Organoid-on-a-chip devices leverage microfluidic systems to simulate the physiological microenvironment of specific organs, offering a more dynamic and flexible setting that can mimic a more comprehensive human biological context. However, the lack of functional vasculature has remained a significant challenge in this technology. Vascularisation is crucial for the long-term culture and in vitro modelling of organoids, holding important implications for drug development and personalised medical approaches. This review provides an overview of research progress in developing vascularised organoid-on-a-chip models, addressing methods for in vitro vascularisation and advancements in vascularised organoids. The aim is to serve as a reference for future endeavors in constructing fully functional vascularised organoid-on-a-chip platforms. © 2024, Chinese Medical Multimedia Press Co Ltd.

The sessile drop method was applied to the experimental investigation of the wetting and spreading behaviors of liquid Mg drops on pure Ni *** comparison,the experiments were performed in two variants:(1)using the Capillary Purification(CP)procedure,which allows the non-contact heating and squeezing of a pure oxide-free Mg drop;(2)by classical Contact Heating(CH)*** high-temperature tests were performed under isothermal conditions(CP:760℃for 30 s;CH:715℃for 300 s)using Ar+5 wt%H_(2) *** the sessile drop tests,images of the Mg/Ni couples were recorded by CCd cameras(57 fps),which were then applied to calculate the contact angles of metal/substrate *** and transmission electron microscopy analyses,both coupled with energy-dispersive X-ray spectroscopy,were used for detailed structural characterization of the solidified *** was found that an oxide-free Mg drop obtained by the CP procedure showed a wetting phenomenon on the Ni substrate(an average contact angleθfollowed by fast spreading and good wetting over the Ni substrate(θ_((CP))~20°in 5 s)to form a final contact angle ofθ_(f(CP))~18°.In contrast,a different wetting behavior was observed for the CH procedure,where the unavoidable primary oxide film on the Mg surface blocked the spreading of liquid Mg showing apparently non-wetting behavior after 300 s contact at the test ***,in both cases,the deep craters formed in the Ni substrates under the Mg drops and significant change in the structure of initially pure Mg drops to Mg-Ni alloys suggest a strong dissolution of Ni in liquid Mg and apparent values of the final contact angles measured for the Mg/Ni system.

Molecular oxygen abundance is a key parameter in understanding the chemical network of the interstellar *** estimate the molecular oxygen column density and abundance for a sample of Galactic massive star formation regions based on observations from the Submillimiter Wave Astronomy Satellite(SWAS)*** obtained an averaged O_(2)spectrum based on this sample using the(SWAS)survey data(O_(2),487.249 GHz,N=3-1,j=3-2).No emission or absorption feature is seen around the supposed central velocity with a total integration time of t_(total)=8.67×10^(3)hr and an rms noise per channel of 1.45 m *** a kinetic temperature T_(kin)=30 K,we derive the 3σupper limit of the O_(2)column density to be 3.3×10^(15)cm^(-2),close to the lowest values reported in Galactic massive star formation regions in previous *** corresponding O_(2)abundance upper limit is6.7×10^(-8),lower than all previous results based on SWAS observations and is close to the lowest reported value in massive star formation *** a galactic scale,our statistical results confirm a generally low O_(2)abundance for Galactic massive star formation *** abundance is also lower than results reported in extragalactic sources.
