Biphasic effect of extracellular ATP on human and rat airways is due to multiple P2 purinoceptor activation

open access: yesRespiratory Research, 2005
Background Extracellular ATP may modulate airway responsiveness. Studies on ATP-induced contraction and [Ca2+]i signalling in airway smooth muscle are rather controversial and discrepancies exist regarding both ATP effects and signalling pathways.

Protease-activated receptor-2 peptides activate neurokinin-1 receptors in the mouse isolated trachea [PDF]

open access: yes, 2006
Protective roles for protease-activated receptor-2 (PAR2) in the airways including activation of epithelial chloride (Cl-) secretion are based on the use of presumably PAR(2)-selective peptide agonists.

Comparative histological, histochemical, and histometric evaluation of the esophagus in two avian species with different feeding habits (Ciconia ciconia and Buteo buteo)

open access: yesThe Anatomical Record, EarlyView.
Histological structure of esophagus. Abstract The aim of this study was to conduct a comparative evaluation of the histological and histochemical organization of the esophagus in two avian species with different feeding ecologies. A total of 6 individuals were used for this purpose (3 storks, 3 common buzzards).

Learning beyond the lab: A gamified approach to anatomy education in a museum‐based experience

open access: yesAnatomical Sciences Education, EarlyView.
Abstract Anatomy education, traditionally rooted in descriptive instruction and cadaveric dissection, is undergoing a significant transformation through the integration of educational technologies and contemporary pedagogical strategies. Among these, active learning methodologies, such as gamified‐based learning, have emerged as approaches designed to ...

Effects of Vanadate on Responses of Guinea-pig Isolated Trachea to Spasmogens

open access: yes, 1993
The effects of vanadate on the contractility of the guinea-pig isolated trachea was examined. Vanadate (0·1 Mm) produced a sustained contraction that was abolished in Ca2+-free EGTA (0·1 Mm)-containing physiological salt solution but was resistant to ...

Histamine and the mechanisms of nausea and vomiting: Translating the uncertain pharmacology of cyclizine

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Abstract Cyclizine is a long‐established, short‐acting drug, registered for preventing motion sickness, post‐operative nausea and vomiting (PONV) and ‘vomiting of known cause’. The latter is not defined but may include pregnancy and patients receiving palliative care, historically accepted without large, controlled trials.

Histochemical localization of adrenergic nerves in the guinea‐pig trachea

open access: yes, 1973
Specific catecholamine fluorescence was demonstrated in guinea‐pig trachea in fine, varicose, nerve fibres running parallel to the tracheal smooth muscle fibres. The density of nerves in tracheal smooth muscle was greater at the laryngeal end than at the

Compliant hydrogel cuff coating with real‐time pressure monitoring and antibiofilm capabilities for ventilator‐associated pneumonia prophylaxis

open access: yesBMEMat, EarlyView.
A soft‐compliant hydrogel cuff coating combines real‐time pressure monitoring with intrinsic antibacterial activity for prophylaxis of ventilator‐associated pneumonia. A flexible pressure‐sensing patch is embedded in the coating to enable wireless dynamic monitoring of endotracheal cuff pressure through Bluetooth.

Role of the epithelial layer in the generation of superoxide anion by the guinea-pig isolated trachea

open access: yesMediators of Inflammation, 1998
The lucigenin-dependent chemiluminescence generation by guinea-pig isolated tracheal two rings preparations was studied. Tracheal preparations stimulated with phorbol myristate acetate (PMA) or opsonized zymosan generated chemiluminescence.
