Histamine: A Mediator of Intestinal Disorders—A Review

open access: yesMetabolites, 2022
Within the gastrointestinal tract, histamine is present at relatively high concentrations, especially during inflammatory processes. Histamine is a biogenic amine with numerous effects on many cell types, mediated by the activation of its four different ...

o‐Terphenyl‐Based Family of Conjugated Macrocycles: Selective Recognition of Phenylalanine in Water and Interaction With Insulin

open access: yesAngewandte Chemie International Edition, EarlyView.
This study presents the synthesis and binding properties of a new family of o‐terphenyl‐based macrocycles, TP[n] (n = 2‐8). The trimer variant efficiently binds phenylalanine in water with a 10‐fold selectivity compared to other amino acids and aromatic neurotransmitters.

Pathophysiological Roles of Histamine Receptors in Cancer Progression: Implications and Perspectives as Potential Molecular Targets

open access: yesBiomolecules, 2021
High levels of histamine and histamine receptors (HRs), including H1R~H4R, are found in many different types of tumor cells and cells in the tumor microenvironment, suggesting their involvement in tumor progression.

A receptor-based analysis of local ecosystems in the human brain. [PDF]

open access: yes, 2017
BackgroundAs a complex system, the brain is a self-organizing entity that depends on local interactions among cells. Its regions (anatomically defined nuclei and areas) can be conceptualized as cellular ecosystems, but the similarity of their functional ...

Ursolic Acid Alleviates Orchitis via Modulating Ferroptosis in Peritubular Myoid Cells of Testis

open access: yesAnimal Research and One Health, EarlyView.
Ursolic acid modulates key ferroptosis‐related pathways in the peritubular myoid cells of the testis in forest musk deer. ABSTRACT Chronic stress adversely affects reproductive health, increasing susceptibility to pathologies such as orchitis. Additionally, the maintenance of iron homeostasis is essential for preserving the function of the testicles ...

Hippocampal histamine receptors and conflictive exploration in the rat: studies using the elevated asymmetric plus-maze

open access: yesBrazilian Journal of Medical and Biological Research, 1997
The possible role of histamine receptors in the hippocampal formation on the exploratory motivation and emotionality of the rat was studied. An elevated asymmetric plus-maze composed of 4 different arms (no walls, single high wall, high and low walls and

Gut Health in Ostriches (Struthio camelus): Insights Into Intestinal Structure, Functions, Microbiome, and Improvement Strategies

open access: yesAnimal Research and One Health, EarlyView.
Our paper systematically reviews the intestinal structure, function, and microbiota of ostriches, along with strategies for improving their gut health. We analyze how these factors collectively influence intestinal homeostasis and ostrich welfare, emphasizing probiotics as a promising intervention to enhance gut health, boost population well‐being, and

Navigating adverse immunostimulation: A practical guide for clinical researchers

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Problem Setting As drug development moves towards more complex products, early clinical development programmes are increasingly hampered by unwanted and/or unexpected activation of the immune system (adverse immune stimulation, AIS). Solution At the Centre for Human Drug Research, we have introduced standardized procedures to make AIS manageable, while
