Olmesartan‐induced gastritis with no lower gastrointestinal symptoms: A case report

open access: yesDEN Open, Volume 6, Issue 1, April 2026.
Abstract A 74‐year‐old man with decreased appetite, weight, and heartburn was referred to our hospital. His medications included olmesartan. Esophagogastroduodenoscopy (EGD) revealed antral‐dominant erosive gastritis and nodular mucosa. A gastric biopsy revealed inflammatory cell infiltration.

Ca2+-permeable AMPA receptors in homeostatic synaptic plasticity

open access: yesFrontiers in Molecular Neuroscience, 2012
Neurons possess diverse mechanisms of homeostatic adaptation to overall changes in neural and synaptic activity, which are critical for proper brain functions.

A case of duodenal pyloric gland adenoma with high‐grade dysplasia arising from ectopic gastric mucosa

open access: yesDEN Open, Volume 6, Issue 1, April 2026.
Abstract Superficial non‐ampullary duodenal epithelial tumor is a rare disease, but its frequency has reportedly been increasing in recent years. We report a case of duodenal pyloric gland adenoma with high‐grade dysplasia arising from ectopic gastric mucosa.

Caffeine-Induced Suppression of GABAergic Inhibition and Calcium-Independent Metaplasticity

open access: yesNeural Plasticity, 2016
GABAergic inhibition plays a critical role in the regulation of neuron excitability; thus, it is subject to modulations by many factors. Recent evidence suggests the elevation of intracellular calcium ([Ca2+]i) and calcium-dependent signaling molecules ...

Materiality and human cognition [PDF]

open access: yes, 2019
In this paper, we examine the role of materiality in human cognition. We address issues such as the ways in which brain functions may change in response to interactions with material forms, the attributes of material forms that may cause change in brain ...

Synaptic Plasticity and Memory: New Insights from Hippocampal Left-Right Asymmetries. [PDF]

open access: yes, 2014
All synapses are not the same. They differ in their morphology, molecular constituents, and malleability. A striking left-right asymmetry in the distribution of different types of synapse was recently uncovered at the CA3-CA1 projection in the mouse ...

Prognosis of Metaplastic Breast Cancer: A Population‐Based Matched Cohort Study

open access: yesCancer Medicine, Volume 15, Issue 2, February 2026.
ABSTRACT Purpose Metaplastic breast cancer (metBC) is a rare subtype of breast cancer known for its challenging management. The impact of this histological subtype on prognosis remains unclear. Methods Data were collected from the Swedish Cancer Registry between 2008 and 2018.

Activation of high and low affinity dopamine receptors generates a closed loop that maintains a conductance ratio and its activity correlate

open access: yesFrontiers in Neural Circuits, 2013
Neuromodulators alter network output and have the potential to destabilize a circuit. The mechanisms maintaining stability in the face of neuromodulation are not well described.

Carcinosarcoma of the Parotid With Osteosarcoma Component: A Case Report

open access: yesClinical Case Reports, Volume 14, Issue 2, February 2026.
ABSTRACT Carcinosarcomas of the salivary gland with osteosarcoma component are very rare, with only 17 cases reported. Despite multiple poor prognostic factors, our patient's outcome was favorable, highlighting the importance of early diagnosis and aggressive treatment in improving prognosis for this aggressive tumor variant.
