Cellulose-Based Materials and Their Application in Lithium-Sulfur Batteries.

Lithium-sulfur (Li-S) batteries are promising candidates for next-generation energy storage due to their high energy density, cost-effectiveness, and environmental friendliness. However, their commercialization is hindered by challenges, such as the polysulfide shuttle effect, lithium dendrite growth, and low electrical conductivity of sulfur cathodes. Cellulose, a natural, renewable, and versatile biopolymer, has emerged as a multifunctional material to address these issues.

Impact of Ex Vivo Bisphenol A Exposure on Gut Microbiota Dysbiosis and Its Association with Childhood Obesity.

Dietary exposure to the plasticiser bisphenol A (BPA), an obesogenic and endocrine disruptor from plastic and epoxy resin industries, remains prevalent despite regulatory restriction and food safety efforts. BPA can be accumulated in humans and animals, potentially exerting differential health effects based on individual metabolic capacity. This pilot study examines the impact of direct ex vivo BPA exposure on the gut microbiota of obese and normal-weight children, using 16S rRNA amplicon sequencing and anaerobic culturing combined methods.

Usefulness of immature platelet fraction measurement in predicting hematologic recovery in patients with acute leukemias undergoing high-intensity chemotherapy and stem cell transplantation.

Background And Objectives: The immature platelet fraction (IPF) count is a parameter that quantifies young and reticulated platelets in peripheral blood, which reflects platelet production in the bone marrow. It has been used as a predictive model for bone marrow recovery in patients with acute leukemia after high-intensity chemotherapy and/or stem cell transplantation. This study aimed to evaluate IPF as a predictor of hematologic recovery in these patients.

2D P-doped carbon nitride as an effective artificial solid electrolyte interphase for the protection of Li anodes.

Metallic lithium plays an important role in the development of next-generation lithium metal-based batteries. However, the uncontrolled growth of lithium dendrites limits the use of lithium metal as an anode. In this context, a stable solid electrolyte interphase (SEI) is crucial for regulating dendrite formation, stability, and cyclability of lithium metal anodes.

Reorganization of the flagellum scaffolding induces a sperm standstill during fertilization.

Mammalian sperm delve into the female reproductive tract to fertilize the female gamete. The available information about how sperm regulate their motility during the final journey to the fertilization site is extremely limited. In this work, we investigated the structural and functional changes in the sperm flagellum after acrosomal exocytosis (AE) and during the interaction with the eggs.
