Selective Synthesis of Oligosaccharides by Mechanochemical Hydrolysis of Chitin over a Carbon‐Based Catalyst

open access: yesAngewandte Chemie, Volume 135, Issue 3, January 16, 2023., 2023
An activated carbon catalyst having weak acid sites hydrolyzes chitin to chitin‐oligosaccharides selectively in the presence of mechanical milling. Our system preferentially cleaves large molecules over small oligomers, thus maximizing the selectivity and yield of chitin‐oligosaccharides.

Antifungal Compounds from the Leaves of Rhynchosia minima

open access: yesChemistry &Biodiversity, Volume 19, Issue 12, December 2022., 2022
Abstract Rhynchosia minima, commonly known as jumby bean, is used as a remedy for respiratory ailments in various parts of the world. It is also used by South African traditional healers to treat heart or chest pain. This study aimed to investigate the bioactive constituents of the leaf extracts of R.

Network structure of inter-industry flows [PDF]

open access: yesPhysica A 392, (2013) 6427-6441, 2012
We study the structure of inter-industry relationships using networks of money flows between industries in 20 national economies. We find these networks vary around a typical structure characterized by a Weibull link weight distribution, exponential industry size distribution, and a common community structure.

Asymmetric preparation of antifungal 1-(4 -chlorophenyl)-1-cyclopropyl methanol and 1-(4 -chlorophenyl)-2-phenylethanol. Study of the detoxification mechanism by Botrytis cinerea [PDF]

open access: yes, 2011
Chiral alcohols are important as bioactive compounds or as precursors to such molecules. On the basis of the different antifungal properties of the enantiopure alcohol derivatives of 4-chlorophenyl cyclopropyl ketone and benzyl 4-chlorophenyl ketone ...

Genotoxicity and Cytotoxicity Exerted by Pesticides in Different Biotic Matrices-An Overview of More Than a Decade of Experimental Evaluation [PDF]

open access: yes, 2014
Agrochemicals represent one of the most important sources of environmental pollution. Although attempts to reduce agrochemical use through organic agricultural practices and the use of other technologies to control pests continue, the problem is still

Epipolythiodioxopiperazine‐Based Natural Products: Building Blocks, Biosynthesis and Biological Activities

open access: yesChemBioChem, Volume 23, Issue 23, December 5, 2022., 2022
Housing sulfur: Certain fungi produce diketopiperazine compounds with a transannular sulfur bridge. These so‐called epipolythiodioxopiperzines are toxic by non‐specifically interacting with intracellular proteins and contribute to fungal pathogenicity. Producer strains serve as bio‐pesticides but also question safety of food fermentation.

Optimal control of anthracnose using mixed strategies [PDF]

open access: yes, 2014
In this paper we propose and study a spatial diffusion model for the control of anthracnose disease in a bounded domain. The model is a generalization of the one previously developed in [14]. We use the model to simulate two different types of control strategies against anthracnose disease. Strategies that employ chemical fungicides are modeled using a

Optimization of the bi-oleothermal treatment process for wood preservation and fireproofing [PDF]

open access: yes, 2011
The bi-oleothermal© process (combination of oil and heat treatment) is a well mastered alternative method for wood protection. However, the fire behavior and resistance to decay of bi-oleothermally treated wood are not good enough to ensure performance ...

Ovarian Function Restoration with Biomimetic Scaffold Incorporating Angiogenic Molecules and Antioxidant in Chemotherapy‐Induced Perimenopausal Model

open access: yesAdvanced Healthcare Materials, EarlyView.
This study developed a biomimetic scaffold incorporating PDRN and melatonin to restore ovarian function in chemotherapy‐induced premature ovarian insufficiency, enhancing cell survival, folliculogenesis, and hormone normalization, while improving fertility rates and offspring in a mouse model, offering a promising strategy for ovarian function ...
