Cardiovascular Plasticity and Adaptation of High‐Altitude Birds and Mammals

open access: yesIntegrative Zoology, EarlyView.
This schematic depicts the cardiovascular adaptations of mammals and birds to high‐altitude hypoxia. It highlights key phenotypic changes in oxygen transport and cardiac responses, driven by molecular mechanisms including transcriptional regulation and genetic modifications.

Nanoparticles in the treatment of chronic lung diseases [PDF]

open access: yes, 2019
Nanoparticles, although considered a topic of modern medicine, actually have an interesting history. Currently, advances in nanomedicine hold great promise as drug carrier systems for sustained release and targeted delivery of diverse therapeutic agents.

The Paediatric BCG Vaccine Century: From Historical Success to Future Innovations

open access: yesActa Paediatrica, EarlyView.
ABSTRACT Aim The tuberculosis (TB) vaccine, Bacille‐Calmette‐Guérin (BCG), protects infants against severe forms of primary TB. Yet, it does not protect against pulmonary reactivation TB in adults. Methods A literature review was conducted between 1st January and 28th February 2025 using PubMed, Google Scholar and reports of the World Health ...

Transcriptomic analysis reveals lipid metabolism and macrophage involvement associated with nintedanib treatment in a rat bleomycin model

open access: yesBritish Journal of Pharmacology, EarlyView.
In this study, nintedanib reduced lung fibrosis in a rat double‐hit bleomycin‐induced model. Transcriptomic analysis revealed two key gene signatures related to the effect of the molecule: one involving mesenchymal cells affecting known fibrotic pathways and another linking mainly macrophages to lipid metabolism.

Experimental pneumonia induced by a Bordetella parapertussis-like organism in the ovine and murine lung : a thesis presented in partial fulfillment (70%) of the requirements for the degree of Master of Philosophy in Veterinary Pathology at Massey University [PDF]

open access: yes, 1987
Thirty-four specific pathogen-free (SPF) Swiss mice were intranasally inoculated with a suspension containing about 3 x 10 7 colony-forming units (CFU)/ml of a B. parapertussis-like organism isolated from pneumonic ovine lung.

Flow‐controlled expiration improves gas exchange in anaesthetised horses undergoing orthopaedic surgery

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background Flow‐controlled expiration (FLEX) has been shown to significantly enhance oxygenation in horses under laboratory conditions. Objective This study aims to corroborate these findings by evaluating the effects of FLEX on gas exchange in a randomised clinical trial involving a large population of clinical horses undergoing orthopaedic ...

3D virtual histology demonstrates tumour connectivity in spread through air spaces (STAS) of non‐small cell lung cancer

open access: yesHistopathology, EarlyView.
STAS‐positive lung nodules were analysed using histology, clinical CT, and synchrotron‐based μCT. μCT enables 3D spatial insights of STAS clusters which appear consistently connected to alveolar or vascular structures, suggesting non‐random distribution.

High prevalence of loss of Claudin‐18 expression in invasive non‐mucinous lung adenocarcinoma: Potential diagnostic implications in routine practice

open access: yesHistopathology, EarlyView.
Loss of Claudin‐18 (Cldn18) expression is a frequent and specific feature of non‐mucinous lung adenocarcinoma (NM‐LUAD). Cldn18 immunohistochemistry may serve as an ancillary tool for distinguishing malignant from non‐neoplastic alveolar epithelium, as well as for differentiating NM‐LUADs with mucin production from M‐LUADs, particularly in small or ...

Pulmonary alveolar microlithiasis: A case report and brief review of literature [PDF]

open access: yesCaspian Journal of Internal Medicine
Background: Pulmonary alveolar microlithiasis (PAM), a rare autosomal recessive pulmonary disease, is mainly characterized by extensive calcium phosphate microliths deposition in the alveoli. The major mutation, causing the characteristic of this disease,
