Rational Design of Multifunctional Tacrine Derivatives as Candidates for the Treatment of Alzheimer and Parkinson Diseases

open access: yesChemMedChem, Volume 21, Issue 15, 14 August 2026.
We present a set of multifunctional tacrine derivatives, designed with the CADMA‐Chem protocol, aimed for Alzheimer and Parkinson diseases. Of the tacrines designed, TAC‐674 and TAC‐678 are the best candidates to act as multifunctional antioxidants and neuroprotectors for Alzheimer and Parkinson diseases, respectively.

Mapping Trofinetide Polypharmacology in Rett Syndrome: A Multi‐Stage Computational Analysis

open access: yesJournal of Computational Chemistry, Volume 47, Issue 21, August 5, 2026.
How can a single molecule address the complex symptoms of Rett syndrome? This computational study maps the multi‐target mechanism of trofinetide, revealing diverse modes of binding across five key receptors: GAT1, GABAA, CHRM1, AMPA, and GSK3β. From deep orthosteric anchoring to dynamic surface interactions, these structural insights provide a rational

Testing the Dry Refuge Model: Paleoecological Insights From Late Pleistocene Gomphotheres in Ecuador

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
We present paleontological evidence that may prove the Dry Refuge Model in Ecuador during the Late Pleistocene. ABSTRACT Paleoenvironmental records indicate that Neotropical regions near the Equator experienced reduced rainfall during the Last Glacial Maximum (LGM). However, some records show conflicting environmental signals.

Probiotic Stability and Antihypertensive Activity of Peptides in Aguamiel Syrup‐Fortified Milk Protein Fermented by Lacticasebacillus rhamnosus GG

open access: yeseFood, Volume 7, Issue 4, August 2026.
This study evaluates the impact of aguamiel syrup on a synbiotic fermented dairy product, focusing on antihypertensive peptide release and Lacticaseibacillus rhamnosus GG survival. While metabolic parameters remained unchanged, aguamiel syrup enhanced bioactive peptide production and antihypertensive activity (45.3%), suggesting its potential as a ...

From Crisis to Resilience: Rethinking Urban Flooding and Groundwater Recharge in Bengaluru City, India

open access: yesWorld Water Policy, Volume 12, Issue 3, August 2026.
ABSTRACT Bengaluru, a primary metropolitan centre in India, is currently grappling with the dual crises of urban flooding and severe groundwater depletion. These challenges are driven by rapid urbanization, which has seen built‐up areas increase from 42% to 86% over two decades, resulting in a dramatic loss of vegetation and wetlands.

Polarized effects of adenosine on blood–brain barrier integrity: Tightening from the luminal and opening from the abluminal side

open access: yesBritish Journal of Pharmacology, Volume 183, Issue 16, Page 4761-4777, August 2026.
Background and Purpose Adenosine as a signalling molecule modifies blood–brain barrier (BBB) tightness in pathological conditions. Our aim was to investigate the direct and polarized effects of adenosine on the BBB using co‐culture and in vivo models. Experimental Approach The expression of adenosine receptors was measured by qRT‐PCR.
