Timing of alveolar cleft bone grafting in maxillary alveolar cleft defects
… to identify the best time for secondary alveolar cleft bone grafting, including chronological age, skeletal age, and dental age. However, few studies have employed objective methods of assessment that would permit statistical analysis. Fifty-nine patients with clefts of the alveolus who …

Articulation of whispered alveolar consonants
… articulation of whispered and normally-spoken alveolar consonants through the use of electropalatography (EPG). While whisper is a well-researched topic, most prior studies have been limited to glottal and acoustic examinations. This study aims to directly measure the articulatory changes …

Cellular Ensembles in Alveolar Homeostasis and Repair
… with different forms of damages. The primary alveolar stem cell, alveolar type-2 cells (AT2s) are sparsely distributed and make up only 5% of the surface area. Despite this organization, AT2s are still able to maintain tissue homeostasis and achieve efficient repair after injury. However, the …

Glycan polymeric prodrugs against pulmonary intracellular alveolar infections
… to target the macrophage mannose receptor on alveolar macrophage cells would eradicate or minimize bacterial replication and allow for better protection against intracellular infections. We demonstrated that mannose polymeric prodrug systems provided significantly improved protection against …

New Aspects of Alveolar Adaptive Immune Responses in COPD
… inflammation in conducting airways and the alveolar parenchyma. The inflammation, which is a consequence of inhalation of noxious gases like tobacco smoke, has traditionally been thought to be driven by innate immune responses. However, more recent studies have revealed an increase in …

Morphological Changes in Alveolar Bone Following Orthodontic Space Closure
… </em>Changes occurring in anterior alveolar bone following orthodontic tooth movement are controversial. Some research has shown that orthodontic tooth movement results in the adaptation of cortical bone; others have shown that it results in dehiscence and fenestrations.</p> …

Influence of Biomaterials in Alveolar Bone Regeneration and Preservation
… bone quantity (in height and thickness). But alveolar bone defects are very frequent, for instance due to periodontitis, traumatism or acute dental infection. Moreover, a simple tooth extraction leads to significant bone resorption. Therefore, alveolar bone regeneration is often necessary in …

YAP/TAZ REGULATES ALVEOLAR REGENERATION AND RESOLUTION OF LUNG INFLAMMATION
Alveolar epithelium plays a pivotal role in protecting the lungs from inhaled infectious agents. Therefore, the regenerative capacity of the alveolar epithelium is critical for recovery from these insults to rebuild the epithelial barrier and restore pulmonary functions. Here, we show that …

Reporte de Caso. Rabdomiosarcoma Alveolar en mama como tumor primario
Introducción El rabdomiosarcoma alveolar (RMS) como tumor primario de mama, es una tipo de cáncer con una alta morbimortalidad a nivel mundial. Se describe la fisiopatología, evolución clínica y tratamiento de un caso de Rabdomiosarcoma alveolar como tumor primario de la mama en un paciente del …

Assessment of Human Alveolar Bone Density by Using Volumetric CT Machine
<p>This study evaluated bone density in designated implants sites using cone-beam computed tomography (CBCT) and compared the measurements to those of quantitative computed tomography (QCT) and subjective bone density evaluation. Sixty-two designated implant sites in 9 human cadavers jaws were …

The role of ceramides in cigarette smoke-induced alveolar cell death
… of emphysema involves disappearance of alveolar structures, in part attributed to alveolar cell apoptosis. The mechanism by which cigarette smoke (CS) induces alveolar cell apoptosis is not known. We hypothesized that ceramides are induced by CS via specific enzymatic pathways that can …

Orthodontic tooth movement and neurotrophins in the rat dento-alveolar complex.
… tooth movement, stress is applied on the dento-alveolar complex, initiating a biological response. This response results in the remodelling of the periodontal ligament and the alveolar bone. When a force is placed on a tooth, the periodontal ligament is stretched and compressed depending on the …

Kinetics and mechanisms of accumulation for liposomal ciprofloxacin into rat alveolar macrophages
… liposomal ciprofloxacin (Lipo-CPFX) into the rat alveolar macrophage NR8383 cells were studied in vitro, in comparison to unformulated ciprofloxacin (CPFX). Upon incubation with CPFX or Lipo-CPFX, cellular drug accumulation was determined from the cell lysates or efflux was from the extracellular …

Alveolar stem cell dynamics and regulatory mechanisms in homeostasis and early oncogenesis
… and progression remain elusive. Although alveolar type II (AT2) cells, which act as stem cells in the alveolar epithelium, have been identified as key cells of origin of LUAD, little progress has been made in understanding the precise sequence of events that transform single AT2 cells into …
