Objective: To develop an individualized prediction model for myelosuppression risk in lung cancer patients undergoing platinum-based doublet chemotherapy and validate its predictive efficacy.
Methods: A retrospective analysis was conducted on the clinical data of 584 lung cancer patients who received platinum-based doublet chemotherapy at The Affiliated Hospital of Qingdao University between January 2016 and December 2020. Patients were randomly assigned to a training cohort (n=391) and a validation cohort (n=193).
Piezo1, which maintains the integrity and function of the intestinal epithelial barrier, is essential for colonic epithelial homeostasis. However, whether and how Piezo1 regulates colon stem cell fate remains unclear. Here, we show that Piezo1 inhibition promotes colon stem cell proliferation.

This study detected miRNA, protein expression, and metabolic substances in the plasma exosomes of horses before and after competition, providing new insights for post-race recovery and care of horses.
Method: Eight three-year-old horses that had undergone training were selected as the research subjects, with four horses that had not competed as the control group and four horses that had participated in the competition for half an hour as the training group.
Chronic stress can affect brain function through various mechanisms, leading to the development of anxiety disorders. The chronic unpredictable mild stress (CUMS) is a classic model of chronic stress. This study evaluated the effects of different durations of CUMS on anxiety-like behavior, inflammation, and tryptophan metabolism in C57BL/6N mice.

To address the pH limitations of traditional Cr(VI) adsorbents, converting Cr(VI) anions into the more stable Cr(III) cations through a reduction reaction is an effective strategy. Therefore, in this study, gallic acid (GA), with a high redox potential, was selected as the reducing agent, together with chitosan (CS) as the substrate, and sodium alginate (SA) as the gelling agent. A novel SCG composite material was successfully prepared using the sol-gel crosslinking method, which efficiently captured and reduced Cr(VI) while immobilizing Cr(III).

This condition typically stems from either insufficient insulin secretion or a functional defect in the insulin itself. Clinically, diabetes is primarily classified into type 1 diabetes mellitus (T1DM) and type 2 diabetes mellitus (T2DM), with T2DM comprising nearly 90% of all diagnosed cases.

Background: Research indicates that there may be an association between plasma lipidome levels and the incidence of diabetic retinopathy (DR) in patients. However, the potential causality of this relationship is yet to be determined. To investigate this matter further, we employed a two-sample Mendelian randomization (MR) analysis to comprehensively assess the causality between lipidome levels and DR.

While theoretical studies suggest that preexisting defects in ice generate "off-lattice" water molecules, triggering bulk ice melting, direct experimental evidence of their form has been lacking as the transparent and transient nature of ice poses significant challenges for observation with current techniques. Here, we introduce an ice-melting-induced lyophilization (IMIL) technique that employs graphene-based nanoprobes to replicate and track liquid evolution within melting bulk ice.
