The role of lipid metabolism in neuronal senescence

open access: yesFEBS Open Bio, Volume 16, Issue 5, Page 857-869, May 2026.
Disrupted lipid metabolism, through alterations in lipid species or lipid droplet accumulation, can drive neuronal senescence. However, lipid dyshomeostasis can also occur alongside neuronal senescence, further amplifying tissue damage. Delineating how lipid‐induced senescence emerges in neurons and glial cells, and how it contributes to ageing and ...

Gut–Brain Connection: Deciphering Causal Pathways Between Gut Microbiota and Neuroimaging Profiles Through Mendelian Randomization

open access: yesFood Science &Nutrition, Volume 14, Issue 5, May 2026.
This graphical abstract illustrates the bidirectional causal relationships between gut microbiota and brain network connectivity identified using Mendelian randomization analysis. Genome‐wide association study data from the MiBioGen consortium (gut microbiota) and the UK Biobank (brain imaging‐derived phenotypes across seven resting‐state networks ...

Collateral and risk sharing in group lending: evidence from an urban microcredit program [PDF]

open access: yes
Empirical research on group lending is extensive, but without allowance for collateral to mitigate strategic default. Indeed, lack of credit access has motivated microcredit in rural areas of developing countries, where agents with collateral are very ...

Unveiling the Bidirectional Relationship on the Effect of Gut Microbiota and Female Infertility: A Narrative Review

open access: yesHealth Science Reports, Volume 9, Issue 5, May 2026.
ABSTRACT Background and Aims Dysbiosis is the substitution of the normal gut flora with a dysfunctional array of organisms that influences the outcome of multiple inflammatory pathways, contributing to systemic inflammation and various disease states. It has historically been understudied, with outcomes that may directly or indirectly cause pathologies.

Carrier screening in the reproductive setting—Are there medical implications for the heterozygote?—A guide for clinicians

open access: yesPregnancy, Volume 2, Issue 3, May 2026.
Abstract Carrier screening for genetic conditions performed preconception or during pregnancy allows identification of fetal risk for inherited autosomal recessive and X‐linked conditions. The goal is to identify at‐risk patients/couples and offer them reproductive options such as preimplantation genetic diagnosis, prenatal testing, or targeted newborn

Enteric Nervous System Damage by Food Contaminants: A Pathway to Neurodegeneration?

open access: yesComprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 3, May 2026.
ABSTRACT The enteric nervous system (ENS), a key component of the gut–brain axis, has emerged as a critical player in the pathogenesis of Parkinson's disease (PD). It is the first neural system exposed to food contaminants (FCs)—a diverse group of ubiquitous toxic compounds fortuitously present in food derived from production, processing, storage, or ...

Fusion of implementers for spinors on the circle

open access: yes, 2019
We consider the space of odd spinors on the circle, and a decomposition into spinors supported on either the top or on the bottom half of the circle. If an operator preserves this decomposition, and acts on the bottom half in the same way as a second ...
