Scaling of shoot and root respiration of woody and herbaceous plants.
Proc Biol Sci
January 2025
Faculty of Engineering, Hokkaido University, Sapporo 060-8628, Japan.
Woody and herbaceous plants are the main components of global terrestrial ecosystems, and their growth, adaptation and survival depend largely on the metabolism of shoots and roots. Therefore, understanding size-scaling of metabolic rates in woody and herbaceous plants, and in shoots and roots, is a fundamental issue in ecology. However, few empirical studies have examined metabolic scaling exponents across a wide range of plant sizes.

Background: Extracellular matrix (ECM) is a three-dimensional (3D) structure found around cells in the tissues of many organisms. It is composed mainly of fibrous proteins, such as collagen and elastin, and adhesive glycoproteins, such as fibronectin and laminin-as well as proteoglycans, such as hyaluronic acid. The ECM performs several essential functions, including structural support of tissues, regulation of cell communication, adhesion, migration, and differentiation by providing biochemical and biomechanical cues to the cells.

The reason why certain bacteria, , (PA), produce acetylated alginate (Alg) in their biofilms remains one of the most intriguing facts in microbiology. Being the main structural component of the secreted biofilm, like the one formed in the lungs of cystic fibrosis (CF) patients, Alg plays a crucial role in protecting the bacteria from environmental stress and potential threats. Nonetheless, to investigate the PA biofilm environment and its lack of susceptibility to antibiotic treatment, the currently developed biofilm models use native seaweed Alg, which is a non-acetylated Alg.

Botany Discipline, School of Biological Sciences and Biotechnology, Goa University, Goa, India.
The dairy industry is a significant sector within the food industries, known for its high-water consumption and consequent generation of dairy wastewater (DWW), which is rich in pollutants like Chemical Oxygen Demand (COD) and Biological Oxygen Demand (BOD). Improper disposal of DWW poses serious environmental challenges, including eutrophication and highlighting the need for sustainable biological treatment methods. This study investigates the potential of indigenous cyanobacterial strains , , , and for the bioremediation of DWW.

Department of Drug Sciences, University of Pavia, Pavia, 27100, Italy.
Purpose: The main purpose of the study was the formulation development of nanogels (NHs) composed of chondroitin sulfate (CS) and low molecular weight chitosan (lCH), loaded with a naringenin-β-cyclodextrin complex (NAR/β-CD), as a potential treatment for early-stage diabetic retinopathy.
Methods: Different formulations of NHs were prepared by varying polymer concentration, lCH ratio, and pH and, then, characterized for particle size, zeta potential, particle concentration (particles/mL) and morphology. Cytotoxicity and internalization were assessed in vitro using Human Umbilical Vein Endothelial Cells (HUVEC).
