Quantitative MRI evaluation of iron deposition in patients with transfusion-dependent thalassemia: clinical management insights.

Background: In patients with thalassemia, different organs are affected differently by iron overload. Nevertheless, the reasons for this could be the same key transporters. This study investigated the iron deposition in different organs of transfusion-dependent thalassemia (TDT) patients and its correlation.

Segmentation tracking and clustering system enables accurate multi-animal tracking of social behaviors.

Accurate analysis of social behaviors in animals is hindered by methodological challenges. Here, we develop a segmentation tracking and clustering system (STCS) to address two major challenges in computational neuroethology: reliable multi-animal tracking and pose estimation under complex interaction conditions and providing interpretable insights into social differences guided by genotype information. We established a comprehensive, long-term, multi-animal-tracking dataset across various experimental settings.

Targeting gut microbiota as a therapeutic target in T2DM: A review of multi-target interactions of probiotics, prebiotics, postbiotics, and synbiotics with the intestinal barrier.

The global epidemic of type 2 diabetes mellitus (T2DM) imposes a substantial burden on public health and healthcare expenditures, thereby driving the pursuit of cost-effective preventive and therapeutic strategies. Emerging evidence suggests a potential association between dysbiosis of gut microbiota and its metabolites with T2DM, indicating that targeted interventions aimed at modulating gut microbiota may represent a promising therapeutic approach for the management of T2DM. In this review, we concentrated on the multifaceted interactions between the gut microbiota and the intestinal barrier in the context of T2DM.

The efficacy and safety of tofacitinib in anti-melanoma differentiation-associated gene 5 antibody positive dermatomyositis associated interstitial lung disease: a systematic review and meta-analysis.

Background: The presence of anti-melanoma differentiation-associated gene 5 (MDA5) antibodies in dermatomyositis (DM) is associated with an increased risk of developing rapidly progressive interstitial lung disease (RP-ILD) and a poor prognosis.

Objectives: We aimed to explore whether tofacitinib could improve the prognosis of Anti-MDA5 antibody positive DM-interstitial lung disease (ILD).

Design: Systematic review and meta-analysis.

Functional Separator with Poly(Acrylic Acid)-Enabled LiCO-Free Garnet Coating for Long-Cycling Lithium Metal Batteries.

Lithium metal batteries (LMBs) possess a theoretical energy density far surpassing that of commercial lithium-ion batteries (LIBs), positioning them as one of the most promising next-generation energy storage systems. Modifying separators with composite coatings comprising oxide solid-state electrolyte (SSE) particles and polymers can improve the cycling stability and safety of LMBs. However, exposure to air forms LiCO on oxide SSE particles, diminishing their ion flux regulation at the electrode/electrolyte interface.

Computed tomography image quality in patients with primary hepatocellular carcinoma: intraindividual comparison of contrast agent concentrations.

Objective: This study aimed to assess the impact of the different concentrations of iodine contrast agents used on the quality of computed tomography (CT) images obtained intraindividually in hepatocellular carcinoma patients.

Methods: In this retrospective study, data from a cohort of 29 patients diagnosed with primary hepatocellular carcinoma who had undergone two preoperative CT-enhanced examinations within a 3-month timeframe were analyzed. Each patient was randomly assigned to receive either a low-concentration contrast agent (300 mg I/mL iohexol) or a high-concentration contrast agent (350 mg I/mL iohexol) for the first scan and the alternative contrast agent for the second scan.

Synchronized long-term delivery of growth hormone and insulin-like growth factor 1 through poly (lactic-co-glycolic acid) nanoparticles on polycaprolactone scaffolds for enhanced osteochondral regeneration.

The regeneration of osteochondral defects is challenging due to the complex structure of the osteochondral unit. This study aimed to develop a biomimetic scaffold by loading growth hormone (GH) and insulin-like growth factor-1 (IGF-1) into poly (lactic-co-glycolic acid) (PLGA) nanoparticles and incorporating them into polycaprolactone (PCL) scaffolds to promote synchronized osteochondral regeneration. The nanoparticles were successfully immobilized onto PCL scaffolds pre-modified with polydopamine (PDA) to enhance cell adhesion and proliferation.

Organ-Specific Iron Overload in Non-Transfusion-Dependent Thalassemia Patients: Insights from Quantitative MRI Evaluation.

Objective: To elucidate the iron load in different organs of non-transfusion-dependent thalassemia (NTDT) patients using magnetic resonance imaging (MRI) T2* scan.

Methods: Thirty-four NTDT patients, including 28 NTDT iron chelation without and 6 NTDT with iron chelation, together with 15 normal controls, underwent MRI examination between December 2022 and July 2024 were enrolled in the study. Measured T2* of the pituitary gland, kidney cortex, heart, liver, pancreas, spleen.

Preparation and characterization of porous corn starch-based antibacterial sustained-release intelligent film.

A novel porous corn starch-based antibacterial sustained-release intelligent film was prepared with the porous corn starch as the substrate, purple corn cob anthocyanin (PCA) as the indicator, and tangerine peel essential oil as the antibacterial agent, and its properties were studied. The results showed that the porous corn starch-based antimicrobial sustained-release indicator film had good mechanical strength, surface hydrophobicity and light transmittance. The tensile strength of the sustained-release indicator film (PLSt-12) prepared by porous corn starch with an enzymatic hydrolysis time of 12 h was 14.

Artificial Electron Channels Enable Contact Prelithiation of Li-Ion Battery Anodes with Ultrahigh Li-Source Utilization.

Contact prelithiation is widely used to compensate for the initial capacity loss of lithium-ion batteries (LIBs). However, the low utilization of the Li source, which suffers from the deteriorated contact interfaces, results in cycling degeneration. Herein, Li-Ag alloy-based artificial electron channels (AECs) are established in Li source/graphite anode contact interfaces to promote Li-source conversion.

Long-term intermittent oral administration of selective COX-2 inhibitor improved the clinical outcomes of COVID-19 in patients with cirrhosis.

Objectives: Patients with cirrhosis are more susceptible to coronavirus disease 2019 (COVID-19) due to immune dysfunction. In this retrospective study we aimed to investigate whether suppression of mild systemic inflammation with selective cyclooxygenase-2 inhibitor (COX-2-I) during chronic care of cirrhotic patients would reduce the occurrence of acute decompensated events and improve patient prognosis of COVID-19.

Methods: Medical records of cirrhotic patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection were sequentially reviewed.
