Direct-effect radiation chemistry of solid-state carbohydrates using EMR and DFT [PDF]

open access: yes, 2010
To contribute to a mechanistic understanding of radical reaction pathways in the sugar-phosphate backbone of DNA, we are investigating primary radicals induced by X-rays, as well as their transformation into stable radicals or diamagnetic products, in ...

Space biomedicine‐oriented bioink and biomimetic blood‒brain barrier

open access: yesVIEW, EarlyView.
Bioinks and bioprinting play a pivotal role in the successful delivery of cell models and the fabrication of tissue models for space biomedicine research. This study investigated the effects of hypergravity and vibration on two‐dimensional adherent cells and three‐dimensional embedded cells and provided methods for storing hybrid bioink and high ...

Hevea brasiliensis seeds: A novel sustainable feedstock for ethanol production

open access: yesVietnam Journal of Chemistry, EarlyView.
Abstract The rubber tree (Hevea brasiliensis) is cultivated on a large scale mainly for the extraction of latex in Brazil and Southeast Asia, also generating large quantities of seeds. These seeds currently do not have large‐scale applications and may thus be considered as a residue.

A bacterial ABC transporter enables import of mammalian host glycosaminoglycans

open access: yesScientific Reports, 2017
Glycosaminoglycans (GAGs), such as hyaluronan, chondroitin sulfate, and heparin, constitute mammalian extracellular matrices. The uronate and amino sugar residues in hyaluronan and chondroitin sulfate are linked by 1,3-glycoside bond, while heparin ...

Recovery of male DNA acquired from carrion‐feeding insects in a simulated sexual assault scenario

open access: yesJournal of Forensic Sciences, EarlyView.
Abstract When bodies of sexual assault victims are discovered in advanced stages of decomposition, the recovery of direct DNA evidence is often compromised, posing a challenge in criminal investigations. This study aimed to determine insect colonization and succession patterns on pig carcasses inoculated with semen and to assess the feasibility of ...

Influence of sugars on the reddening of triturated florets of dyer's saffron flowers

open access: yesActa Societatis Botanicorum Poloniae, 2014
Pentoses, hexoses and disaccharides were administered to the triturated florets of dyer's saffon (Carthamus tinctorius) and their effects on enzyme-catalyzed floret reddening examined spectrophotometically.

Dynamics of water of hydration near disaccharides strongly depends on solute topology: mapping density fluctuations, rotational anisotropy and h-bond exchange mechanism around disaccharides [PDF]

open access: yes, 2012
comunicação em posterDisaccharides such as trehalose are abundant components of cells and may alter the phase behavior or dynamics of phospholipid bilayers: for example, trehalose is a cryoprotectant of lipid bilayers.

Novel therapeutic targets for chronic visceral pain in gastrointestinal disorders

open access: yesBritish Journal of Pharmacology, EarlyView.
Chronic visceral pain imposes a major clinical challenge in gastroenterology and beyond, profoundly impacting patients' quality of life. However, limited understanding of its complex, multifaceted pathophysiology, encompassing both peripheral and central mechanisms, continues to impede the development of effective management strategies.

Effects of Common Food Additives Kappa‐, Iota‐ and Lambda‐Carrageenans on Intestinal Epithelial Cell Activation and Barrier Disruption

open access: yesClinical &Experimental Allergy, EarlyView.
Carrageenans, widely used food additives, disrupted intestinal epithelial integrity in a gut‐on‐a‐chip model. All types (κ‐, ɩ‐, λ‐) induced cytotoxicity, inflammation and tight junction (TJ) disruption, triggering TNF‐mediated immune responses. λ‐Carrageenan had the most severe effects, supporting the Epithelial Barrier Theory linking food additives ...

The Parasitoid Wasp Glyptapanteles porthetriae Induces a Photoperiod‐Dependent Diapause‐Like State in Its Potential Overwintering Host Lasiocampa quercus

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
We evaluated Lasiocampa quercus as an overwintering host for the koinobiont larval endoparasitoid Glyptapanteles porthetriae by exposing parasitized larvae to different environmental conditions and comparing parasitoid development with that in the primary host Lymantria dispar.
