Pulmonary emphysema is characterized by the irreversible loss of pulmonary alveoli. Despite recent advances in the understanding this disease, its treatment remains palliative. In this review, we will successively review the data suggesting (1) that alveolar regeneration systems are functional in the mammalian lung and have the potential to regrow lost alveoli, (2) that cigarette smoke, the mai...

Here we describe a new eusuchian crocodyliform, collected 130 years ago from shallow marine limestone of the late Eocene (Priabonian) fossil locality Cluj-Mănăștur, Transylvania, Romania. Diplocynodon kochi n. sp. is represented by three-dimensionally preserved incomplete skull that may have belonged to mature individual. The taxon possesses relatively narrow and elongated snout mediolaterally ...

Corona virus disease 2019 (COVID-19), a viral infection that was discovered at the end of December in Wuhan, China. The spread and transmission this is very fast even to all countries world. Meanwhile, Acute Respiratory Distress Syndrome (ARDS) an emergency condition field pulmonology occurs due fluid accumulation alveoli causes gas exchange disorders so oxygen distribution tissues were reduced...

The aim of the present study was to identify properties of pure collagen for augmentation techniques and compare to a proved xenogenic material and natural bone regeneration. For that the osteogenesis of extraction alveoli after augmentation with a collagen cone covered with an absorbable collagen membrane in a single product (PARASORB Sombrero®, Resorba) was evaluated in a pig model. Extractio...

Female rats and mice have smaller and, per body mass (BM), more alveoli and alveolar surface area (Sa) than males of their respective species. This sexual dimorphism becomes apparent about the time of sexual maturity. It is prevented in rats (not tested in mice) by ovariectomy at age 3 wk. In female mice, estrogen receptor (ER)-alpha and ER-beta are required for formation of alveoli of appropri...

Endotoxin (Lipopolysaccharide, LPS) is a potent inducer of inflammation and there is various LPS contamination in the environment, being a trigger of lung diseases and exacerbation. The objective of this study was to assess the time course of inflammation and the sensitivities of the airways and alveoli to targeted LPS inhalation in order to understand the role of LPS challenge in airway diseas...

of lungs obtained at necropsy from 44 children at or above the 50th centile dying from non-pulmonary causes were described. In the present paper some results from the analysis of 92 further pressure-volume curves are described. These were compared with the theoretically normal values according to total body length, by dividing the observed value by the theoretically normal one. This was done fo...

BACKGROUND Many animal models have been developed to study bronchopulmonary dysplasia (BPD). The preterm rabbit is a low-cost, easy-to-handle model, but it has a high mortality rate in response to the high oxygen concentrations used to induce lung injury. The aim of this study was to compare the mortality rates of two models of hyperoxia-induced lung injury in preterm rabbits. METHODS Pregnan...
