October 2024

Université de Bordeaux, CNRS, Bordeaux INP, Laboratoire de chimie des polymères organiques (LCPO), UMR 5629, F-33600 Pessac, France.

Article Synopsis
  • Alginates are marine polysaccharides that can bind calcium ions and form hydrogels, making them useful in the biomedical field, though their production as nanogels is difficult.
  • The study introduces a self-assembly method to create stable alginate-based nanogels by combining guluronate blocks from alginates with dextran chains, resulting in micellar structures in the presence of divalent ions.
  • Using techniques like dynamic light scattering and small-angle neutron scattering, researchers found that these micelles have a consistent size of about 8 nm and can exchange ions, demonstrating dynamic behavior even in the presence of agents that can disassemble them.

Genetic-Dependent Brain Signatures of Resilience: Interactions among Childhood Abuse, Genetic Risks and Brain Function.

bioRxiv

September 2024

National Clinical Research Center for Aging and Medicine at Huashan Hospital, MOE Key Laboratory of Computational Neuroscience and Brain-Inspired Intelligence, Institute of Science and Technology for Brain-Inspired Intelligence, Fudan University, Shanghai 200433, China.

Article Synopsis
  • Resilience to emotional disorders in adolescents, particularly after childhood abuse, is influenced by brain responses to environmental stressors, but the specific brain signatures of resilience are still being studied.
  • Research identified two brain networks linked to resilience, with a notable finding that girls with greater activation in a specific orbitofrontal network experienced fewer emotional symptoms after childhood abuse when they had a higher genetic risk for depression.
  • The study suggests these genetic influences on brain activity can predict emotional disorders in late adolescence, highlighting the potential for developing resilience-based interventions to improve adolescent mental health.

Several high-quality, randomized, sham-controlled trials have provided evidence supporting the efficacy and safety of radiofrequency, ultrasound and alcohol catheter-based renal denervation (RDN) for reducing blood pressure (BP). A French clinical consensus document has therefore been developed to propose guidance for the appropriate use of RDN in the management of hypertension along with a dedicated care pathway and management strategy. The French experts group concluded that RDN can serve as an adjunct therapy for patients with confirmed uncontrolled, resistant essential hypertension despite treatment with≥3 antihypertensive drugs, including a long-acting calcium channel blocker, a renin-angiotensin system blocker and a thiazide/thiazide-like diuretic at maximally tolerated doses.

Electronic address:

Article Synopsis
  • Lipid droplets (LD) are essential for storing triglycerides and play a significant role in regulating inflammation in cells, influenced by adipose triglyceride lipase (ATGL).
  • The study examined the effects of inhibiting ATGL and the genetic loss of ATGL in microglia on inflammatory responses, particularly focusing on cytokine expression and phagocytosis during LPS-induced inflammation.
  • Findings showed that ATGL inhibition led to reduced expression of pro-inflammatory cytokines (like IL-1β and IL-6), decreased inflammation-related behaviors, and altered lipid profiles, signifying ATGL's critical role in modulating neuroinflammatory responses.

Unravelling taphono-myths. First large-scale study of histotaphonomic changes and diagenesis in bone from modern surface depositions.

PLoS One

September 2024

Skeletal Biology and Forensic Anthropology Research Group, School of Archaeology and Anthropology, Australian National University, Canberra, Australian Capital Territory, Australia.

The use of diagenetic alterations in bone microstructure ('histotaphonomy') as indicators of funerary treatment in the past and for post-mortem interval calculations in forensic cases has received increasing attention in the last decade. Studies have used histological changes to conclude in-situ decomposition, mummification, infanticide and post-mortem interval. There has been very little attempt to experimentally validate the links between decomposition, depositional conditions, time-since-death and microscopic changes in human bone so that meaningful interpretations of archaeological and forensic observations can be made.

Molar Incisor Hypomineralisation as a Dental Caries Risk Factor - Is It True?

Monogr Oral Sci

September 2024

Department of Cariology, Centre for Dentistry and Oral Hygiene, University of Groningen, University Medical Centre Groningen, Groningen, The Netherlands.

The development of the human dentition is susceptible to disruption owing to its intricate and delicate nature, encompassing variations in tooth number, anatomical configuration, and the characteristics of enamel, dentine, and cementum. This chapter will specifically address the prevalent defect of molar incisor hypomineralisation (MIH), which can impose a significant treatment burden on individuals. MIH is linked to deleterious alterations in the properties of affected enamel, which can lead to rapid enamel breakdown and carious lesion formation in those at a heightened caries risk.

Coping with collapse: Functional robustness of coral-reef fish network to simulated cascade extinction.

Glob Chang Biol

September 2024

Mediterranean Institute for Agriculture, Environment and Development (MED), Global Change and Sustainability Institute (CHANGE), Institute for Advanced Studies and Research (IIFA), University of Evora, Evora, Portugal.

Human activities and climate change have accelerated species losses and degradation of ecosystems to unprecedented levels. Both theoretical and empirical evidence suggest that extinction cascades contribute substantially to global species loss. The effects of extinction cascades can ripple across levels of ecological organization, causing not only the secondary loss of taxonomic diversity but also functional diversity erosion.

An Expedient Route to Bio-Based Polyacrylate Alternatives with Inherent Post-Chemical Modification and Degradation Capabilities by Organic Catalysis for Polymerization of Muconate Esters.

Angew Chem Int Ed Engl

December 2024

Laboratoire de Chimie des Polymères Organiques (LCPO), Université de Bordeaux, CNRS, Bordeaux INP, UMR 5629, 16 av. Pey Berland, 33607, Pessac cedex, France.

The quest for polymers that would be at the same time bio-based and degradable after usage, in addition to offering chemical post-modification options, remains a daunting challenge in contemporary polymer science. Despite advances in polymer chemistry, attempts at controlling the chain-growth polymerization of muconate esters remain unexplored. Here we show that dialkyl muconates can be rapidly polymerized by organocatalyzed group transfer polymerization (O-GTP).
