Modeling the continua in the outcomes of biotic interactions

open access: yesEcology, Volume 104, Issue 4, April 2023., 2023
Abstract The outcome of many ecological interactions lies somewhere along a continuum between pure positive and pure negative effects. Although the popularity of this idea has notoriously risen in the last decades, with the occurrence of continua in interaction outcomes invoked for a wide variety of interactions, the absence of a precise theoretical ...

Recent Advances in the Development and Synthesis of Carbohydrate‐Based Molecules with Promising Antibacterial Activity

open access: yesEuropean Journal of Organic Chemistry, Volume 26, Issue 4, January 24, 2023., 2023
In this review, the potential of carbohydrates as starting materials for the synthesis of antimicrobial agents is explored. The most recent and successful reports of sugar‐based bactericides, bacteriostatic agents, and adhesin binders are covered with focus on the methodologies employed in their synthesis, resulting in a useful compilation of state‐of ...

Enhanced Gene Delivery Triggered by Dual pH/Redox Responsive Host‐Guest Dimerization of Cyclooligosaccharide Star Polycations

open access: yesMacromolecular Rapid Communications, Volume 43, Issue 11, June 2022., 2022
Star polycations consisting of a central trehalose‐based cyclooligosaccharide and radial tetraethyleneimine arms form supramolecular dimers with bis‐adamantane guests that are preorganized for pDNA condensation. The incorporation of a redox‐sensitive disulfide bridge on the guest structure enables a dual pH/redox‐sensitive regulation mechanism that ...

Integrated Assessment of Indoor Air Pollution and Associated Health Risks in a Hemodialysis Unit

open access: yesIndoor Air, Volume 2026, Issue 1, 2026.
Indoor air quality (IAQ) is critical for protecting occupant health, particularly in healthcare settings such as hemodialysis (HD) units, where patients spend prolonged periods indoors. This study assessed IAQ in an HD treatment room over 1 year, identified pollutant sources using indoor/outdoor (I/O) ratios, and evaluated associated health risks for ...

Handling Parameter Variations during the Treatment of Type 1 Diabetes Mellitus: In Silico Results

open access: yesMathematical Problems in Engineering, Volume 2019, Issue 1, 2019., 2019
Type 1 diabetic patients need a strict treatment to regulate blood glucose concentration in a target range. Despite the development of different control strategies, the model parameter variations, given by physiological changes, can generate an inaccurate treatment and in consequence hyperglycemia and hypoglycemia episodes.

Seasonal Breeding and Morphological Variation Across Age and Sex in the Antioquia Brushfinch (Atlapetes blancae)

open access: yesEcology and Evolution, Volume 15, Issue 11, November 2025.
The reproductive season of A. blancae most likely spans from February through August with peak reproductive activity during May, and is highly correlated to day length, and precipitation during the first rainy season of the year, furthermore, it is also highly correlated with the reproductive activity of many other species in the genus Atlapetes ...
