Histone deacetylase 3 controls lung alveolar macrophage development and homeostasis

open access: yesNature Communications, 2020
Alveolar macrophages are known to derive from embryonic precursors although the regulation of this process is poorly understood. Here the authors propose a key role for histone deacetylase 3 as an epigenetic regulator of lung alveolar macrophage ...

Rehabilitation of the alveolar bone after tooth extraction. Analysis of methods

open access: yesЭндодонтия Today, 2020
Resorption of the alveolar bone after tooth extraction is an irreversible process due to biological bone remodeling. It will greatly complicate the further treatment of patients for dental implantation, since for the latter a prerequisite is a sufficient

Alveoloplasty: A Case Report of Recontouring The Alveolar Process

open access: yesInternational Journal of Research in Pharmaceutical Sciences, 2020
Alveoloplasty is one of the common pre-prosthetic surgical procedure carried out in dental surgical practice setups. A. T. Willard in 1853 advocated reduction of the alveolar ridge to bring about the complete proximity of soft tissues over the alveolus. Sir O. T.

Can the reduced level of alveolar bone in the initial stages of juvenile periodontitis anterior to the first molar be explained as arrest in alveolar bone growth?

open access: yesDental Hypotheses, 2013
Introduction : It is generally agreed that juvenile periodontitis is more likely caused by genetic factors than environmental/bacterial factors. Until now, all research reports focus on alveolar bone destruction as a characteristic symptom.

Clinical classification of tooth position in the alveolar bone housing with periodontal defects

open access: yesJournal of Dental Sciences, 2021
A new classification of tooth position in the alveolar bone housing, which indicates the width of alveolar bone for buccolingual direction, with bone defects caused by periodontal disease is proposed.

Quantification of Alveolar Recruitment for the Optimization of Mechanical Ventilation using Quasi-static Pressure Volume Curve [PDF]

open access: yesarXiv, 2018
Quasi-static, pulmonary pressure-volume (P-V) curves over an inflation-deflation cycle are analyzed using a respiratory system model (RSM), which had been developed for quantitative characterization of the mechanical behavior of the total respiratory system.

Crossed hemifacial hyperplasia: A diagnostic dilemma

open access: yesJournal of Indian Society of Pedodontics and Preventive Dentistry, 2007
Crossed hemifacial hyperplasia is a rare condition producing facial asymmetry and overgrowth of the extremities of the opposite side. Very few cases are reported in literature.

Evidence of Chaotic Mixing in the Alveolar Region of the Lung [PDF]

open access: yesarXiv
We report an experimental and numerical investigation to study the role of asymmetry in the expansion-contraction of the acinar wall on the particle transport in the acinus. We model the acinar flow feature using a T-section by appropriately matching the dimensionless numbers to that in the acinus of healthy human subjects.
