Our current understanding of unilateral condylar hyperplasia (UCH) was put forth by Obwegeser. He hypothesized that UCH is 2 separate conditions hemimandibular hyperplasia and hemimandibular elongation. This hypothesis was based on the following 3 assumptions 1) the direction of overgrowth, in UCH, is bimodal-vertical or horizontal, with rare cases growing obliquely; 2) UCH can expand a hemimandible with and without significant condylar enlargement; and 3) there is an association between the condylar expansion and the direction of overgrowth-minimal expansion resulting in horizontal growth and significant enlargement causing vertical displacement. The purpose of this study was to test these assumptions.

We analyzed the computed tomography scans of 40 patients with UCH. First, we used a Silverman Cluster analysis to determine how the direction of overgrowth is distributed in the UCH population. Next, we evaluated the relationship between hemimandibular overgrowth and condylar enlargement to confirm that ov hyperplasia and hemimandibular elongation. It also provides new insights about the pathophysiology of UCH.Homologous recombination (HR) is essential for maintaining genome stability. Although Rad51 is the key protein that drives HR, multiple auxiliary factors interact with Rad51 to potentiate its activity. Here, we present an interdisciplinary characterization of the interactions between Rad51 and these factors. Through structural analysis, we identified an evolutionarily conserved acidic patch of Rad51. The neutralization of this patch completely abolished recombinational DNA repair due to defects in the recruitment of Rad51 to DNA damage sites. This acidic patch was found to be important for the interaction with Rad55-Rad57 and essential for the interaction with Rad52. Furthermore, biochemical reconstitutions demonstrated that neutralization of this acidic patch also impaired the interaction with Rad54, indicating that a single motif is important for the interaction with multiple auxiliary factors. We propose that this patch is a fundamental motif that facilitates interactions with auxiliary factors and is therefore essential for recombinational DNA repair.A key component of outbreak control is monitoring public perceptions and public response. To determine public perceptions and public responses during the first 3 months of the coronavirus disease (COVID-19) outbreak in the Netherlands, we conducted 6 repeated surveys of ≈3,000 persons. Generalized estimating equations analyses revealed changes over time as well as differences between groups at low and high risk. Overall, respondents perceived the risks associated with COVID-19 to be considerable, were positive about the mitigation measures, trusted the information and the measures from authorities, and adopted protective measures. Substantial increases were observed in risk perceptions and self-reported protective behavior in the first weeks of the outbreak. Individual differences were based mainly on participants' age and health condition. We recommend that authorities constantly adjust their COVID-19 communication and mitigation strategies to fit public perceptions and public responses and that they tailor the information for different groups.Alveolar epithelial type II (AT2) cells secrete pulmonary surfactant via lamellar bodies (LBs). Abnormalities in LBs are associated with pulmonary disorders, including fibrosis. However, high-content screening (HCS) for LB abnormalities is limited by the lack of understanding of AT2 cell functions. selleck kinase inhibitor In the present study, we have developed LB cells harboring LB-like organelles that secrete surfactant proteins. These cells were more similar to AT2 cells than to parental A549 cells. LB cells recapitulated amiodarone (AMD)-induced LB enlargement, similar to AT2 cells of patients exposed to AMD. To reverse AMD-induced LB abnormalities, we performed HCS of approved drugs and identified 2-hydroxypropyl-β-cyclodextrin (HPβCD), a cyclic oligosaccharide, as a potential therapeutic agent. A transcriptome analysis revealed that HPβCD modulates lipid homeostasis. In addition, HPβCD inhibited AMD-induced LB abnormalities in human induced pluripotent stem cell-derived AT2 cells. Our results demonstrate that LB cells are useful for HCS and suggest that HPβCD is a candidate therapeutic agent for AMD-induced interstitial pneumonia.

Real-life pharmacological treatment patterns of patients with interstitial lung diseases (ILD) remain elusive.

The objective of this study was to determine how often and with what medications patients with ILD are treated in Canadian tertiary care clinics.

All patients with ILD prospectively enrolled in the Canadian Registry for Pulmonary Fibrosis were included in this observational study. All first instances of medication for each patient were compiled. Time between the diagnosis of ILD and the first initiation of an ILD-related medication was compared across diagnostic categories. Cox proportional hazards models were used to identify variables associated with time-to-treatment initiation, stratified by diagnostic category.

Out of 2,652 patients, a total of 1,483 (56%) were treated with an ILD-related medication during the median follow-up of 3.0 years (1.4 to 5.9), including 349/646 (54%) patients with idiopathic pulmonary fibrosis (IPF) who received an antifibrotic. Patients with IPF were treated earlier and in greater proportion compared to those with non-IPF ILD (p=0.001). Male sex and lower lung function were associated with shorter time to treatment initiation in the full cohort.

Overall, 56% of patients with ILD seen across seven Canadian specialized ILD clinics received pharmacological treatment over a median follow-up of 3 years. Further studies are needed to assess longitudinal patterns of treatment and their influence on key outcomes.
