Acute kidney injury (AKI) predominantly affects hospitalized patients, particularly those in intensive care units, and has emerged as a significant global public health concern. Several factors, including severe cardiovascular disease, surgery-induced renal ischemia, nephrotoxic drugs, and sepsis, contribute to the development of AKI. Despite the implementation of various clinical strategies to prevent or treat AKI, its morbidity and mortality remain high, and there are no clinically effective therapeutic agents available.

Compared with the traditional extraction process, ultrasound has been used to enhance the extraction efficiency of various plant-based proteins. To reveal the mechanism of ultrasound-enhanced extraction of proteins, adaptive neuro-fuzzy inference system (ANFIS) algorithm and numerical simulation based on Fick's law were applied to illustrate the mass transfer behavior of millet proteins under different ultrasonic conditions including solid-liquid ratios (S/L ratios), pH and acoustic energy density levels (AED).

Objective: To determine trends in gallbladder cancer incidence and mortality rates over 12 years and quantitatively analyze the influence of demographic factors on these rates in China.
Methods: We performed a retrospective study of 98,860 Chinese citizens using the Chinese Cancer Registry, a national database.
Background: The administration of platinum-based drugs such as cisplatin and its derivatives, which are frequently used during clinical chemotherapy, is highly restricted due to the incidence of nephrotoxicity. The present study focused on investigating cisplatin-induced nephrotoxicity from the perspective of energy metabolism, renal transporter expression and urinary toxin accumulation.
Methods: This study investigated cisplatin's toxic effects, including nephrotoxicity, cardiotoxicity, hepatotoxicity, pulmonary toxicity, and splenotoxicity.
Acute kidney injury (AKI) is a worldwide public health problem with high morbidity and mortality. Cisplatin is a widely used chemotherapeutic agent for treating solid tumors, but the induction of AKI restricts its clinical application. In this study, the effect of cisplatin on the expression of organic ion transporters was investigated through in vivo and in vitro experiments.

Compared with white rice (WR), colored rice (CR) has more nutritional value because it contains rich active ingredients. In this study, the potential mechanism of CR (red rice (RR), green rice (GR), black rice (BR), and purple rice (PR)) for immunomodulation was explored by UPLC-Q-TOF, network pharmacology, and cell experiment.

Study Design: An experimental study. Place and Duration of the Study: Experimental Animal Laboratory of Lanzhou University, Gansu, China, and the Department of Pharmacy, The First Hospital of Lanzhou University, Gansu, China, from July 2022 to October 2023.
Early identification of drug-induced acute kidney injury (AKI) is essential to prevent renal damage. The renal tubules are typically the first to exhibit damage, frequently accompanied by changes in renal tubular transporters. With this in mind, we have identified an endogenous substrate of the renal tubular transporters that may serve as a biomarker for early detection of drug-induced AKI.

The renal tubular organic cation transporter 2 (OCT2) and multidrug and toxin extrusion protein 1 (MATE1) mediate the vectorial elimination of many drugs and toxins from the kidney, and endogenous biomarkers for vectorial transport (OCT2-MATE1) would allow more accurate drug dosing and help to characterize drug-drug interactions and toxicity. Human serum uptake in OCT2-overexpressing cells and metabolomics analysis were carried out. Potential biomarkers were verified in vitro and in vivo.

Methods: 108patients were divided into two groups: pneumonia group (52 cases) and non-pneumonia group (56 cases), according to whether the patients developed SAP within 7 days of admission. General information was compared between the two groups, like age, gender, history of hypertension, diabetes mellitus, cardiovascular disease, dysphagia, smoking and alcoholhistory.
Renal tubular secretion mediated by organic anion transporters (OATs) and the multidrug resistance-associated protein 4 (MRP4) is an important means of drug and toxin excretion. Unfortunately, there are no biomarkers to evaluate their function. The aim of this study was to identify and characterize an endogenous biomarker of the renal tubular OATs-MRP4 channel.

However, there are many limitations for drug dosage adjustment based on serum creatinine levels, one of which is the limited understanding of creatinine's tubular transport. Thus, we aimed to complement and advance the renal tubular transport of creatinine by activity-based protein profiling (ABPP) and transporter-overexpression technology.

As a result, the knockout of either OAT1 or OAT3 is not reflected in a change in the excretion of organic anionic substrates. To date, only the mOAT1 and mOAT3 individual knockout mouse models have been available.
