Histamine-induced constriction of canine peripheral lung: An airway or tissue response?

open access: yes, 1991
We compared the histamine responsiveness of peripheral airways (less than 6.0 mm diam) and parenchymal tissues in eight anesthetized paralyzed open-chest mongrel dogs.

Immune regulation by histamine and histamine-secreting bacteria

open access: yes, 2017
Histamine is a biogenic amine with extensive effects on many immune cell types. Histamine and its four receptors (H1R-H4R) represent a complex system of immunoregulation with distinct effects dependent on receptor subtypes and their differential ...

Repurposing antimicrobial agents for neuroprotection: Mechanisms, clinical potential, and challenges

open access: yesNeuroprotection, EarlyView.
Antimicrobial agents exert neuroprotective effects through modulation of interconnected pathways. Tetracyclines, macrolides, antimalarial agents, sulfones, and antiparasitic agents suppress neuroinflammation, oxidative stress, and apoptosis while preserving mitochondrial function and neurotransmission.

Selection and Test of L-histidine Decarboxylase Enzyme Activity of Six Isolates of Histamine Forming Bacteria

open access: yesMakara Seri Sains, 2007
Six isolates of histamine forming bacteria were screened to see the degree of ability in producing histamine on modified Niven's medium. The result showed that the six bacteria were able to produce histamine by giving a pinkish color on the medium, which

Pharmacokinetic and Pharmacodynamic Interactions Between Anti‐Asthma Drugs and Medicinal Plants: A Comprehensive Review

open access: yesPhytotherapy Research, EarlyView.
ABSTRACT Asthma affects 260–300 million people worldwide. About 20%–35% of patients use medicinal plants with their asthma medication, often without telling their clinicians. Disclosure rates are low; up to 42% of asthma outpatients use herbal products, with no records in their charts.

Plant‐Derived Bioactives and PPAR Signaling in Functional Dyspepsia: Mechanistic Insights and Therapeutic Perspectives

open access: yesPhytotherapy Research, EarlyView.
Functional dyspepsia involves duodenal barrier dysfunction, low‐grade immune activation and altered neuroimmune signalling. Various plant‐derived bioactives may modulate PPAR signalling, reduce inflammatory and oxidative stress, and support epithelial, immune, metabolic, and sensory homeostasis.

Toll‐Like Receptor 4 Signaling in Natural N‐Acylethanolamines and Derivative NAE‐Like Compounds: Mechanisms and Implications for Neuroimmune and Inflammatory Processes in a Systematic Search Approach

open access: yesPhytotherapy Research, EarlyView.
ABSTRACT N‐acylethanolamines (NAEs) are endogenous fatty acid amides structurally related to the endocannabinoid anandamide and function as bioactive lipid mediators with broad regulatory roles in inflammation and neuroinflammation. Among pattern‐recognition receptors, Toll‐like receptor 4 (TLR4) occupies a central position in innate immune ...

Non-Enzymatic Selective Detection of Histamine in Fishery Product Samples on Boron-Doped Diamond Electrodes

open access: yesBiosensors
Histamine sensing that uses enzymatic reactions is the most common form of testing due to its selectivity for histamine. However, enzymes are difficult to store for long periods of time, and the inactivation of enzymes decreases the reliability of the ...
