Subregional Functional Connectivity of the Precuneus as a Preclinical Biomarker in Alzheimer’s Disease

open access: yesNeurology Research International, Volume 2026, Issue 1, 2026.
Introduction The precuneus (Pc) is a central hub integrating diverse brain functions, and it is early involved in Alzheimer’s disease (AD) pathophysiology, yet its subregional vulnerability remains poorly understood. This study aims to delineate the differential involvement and vulnerability of these subdivisions in the early stages of AD.

Differential gene expression in Chorthippus parallelus (Zetterstedt, 1821) (Orthoptera: Acrididae: Gomphocerinae) induced by Wolbachia infection

open access: yesInsect Science, Volume 32, Issue 6, Page 2105-2124, December 2025.
Distinct lineages of the grasshopper Chorthippus parallelus (Orthoptera: Acrididae) form a well‐known hybrid zone (HZ) in the Pyrenees mountain range; the Iberian endemism C. p. erythropus (Cpe) and the subspecies C. p. parallelus, (Cpp) widely distributed throughout the rest of Europe. Both subspecies differ in diverse traits, including the strains of

Neurotoxic amyloid β‐peptide and tau produce cytokine‐like effects on PMCA in glioblastoma cell lines, enhancing its activity and isoforms expression

open access: yesFEBS Open Bio, Volume 15, Issue 8, Page 1350-1364, August 2025.
Two biomarkers of Alzheimer's disease, amyloid β‐peptide (Aβ) and tau, induce the transformation of U‐251 and other glioblastoma cell lines into neurotoxic A1‐like reactive astrocytes. This transformation is produced by cytokines and is followed by upregulation of PMCA activity and isoform expression, and is closely associated with inflammation, as ...

Salivary/Serum Progesterone Ratio Differs Between Menstrual Cycle Phases but Not Between Populations: Implications for Health, Reproductive, and Behavioral Research

open access: yesAmerican Journal of Human Biology, Volume 37, Issue 7, July 2025.
Scatterplot of paired measurements of PFree‐SAL (y‐axis, log scale) versus PTotal‐VEN (x‐axis, log scale) for each of our 36 Bolivian study participants. Dotted diagonals represent lines of constant uptake fraction (UF = PFree‐SAL/PTotal‐VEN) from 0.2% to 100%. The solid red line represents the linear regression model for luteal phase pairs (red dots),
