Gaining Insight into SARS-CoV-2 Infection and COVID-19 Severity Using Self-supervised Edge Features and Graph Neural Networks [PDF]

arXiv, 2020
A molecular and cellular understanding of how SARS-CoV-2 variably infects and causes severe COVID-19 remains a bottleneck in developing interventions to end the pandemic. We sought to use deep learning to study the biology of SARS-CoV-2 infection and COVID-19 severity by identifying transcriptomic patterns and cell types associated with SARS-CoV-2 ...

Experimental Pulmonary Granuloma Mimicking Sarcoidosis Induced by Propionibacterium acnes in Mice [PDF]

, 2010
Propionibacterium acnes has been implicated as an etiologic agent of sarcoidosis since the isolation of this bacterium from sarcoid lesions. We experimentally produced a murine pulmonary granuloma model using P.

Semaphorin 3E–Plexin D1 Axis Drives Lung Fibrosis through ErbB2‐Mediated Fibroblast Activation

Advanced Science, EarlyView.
TGF‐β1 stimulation in fibroblasts leads to increased Furin expression, Furin‐mediated cleavage of P87‐Sema3E to P61‐Sema3E, which affects fibroblast function through the autocrine pathway, and the P61‐Sema3E‐PlexinD1 axis promotes fibroblast activation, proliferation and migration by affecting ErbB2 phosphorylation, which in turn activates the ErbB2 ...

Imaging of acute dissemination of tuberculosis caused by alveolar lavage surgery in endobronchial tuberculosis characterized by caseous necrosis

Respirology Case Reports
Large amount of caseating overlying on bronchus were detected under bronchoscopy in our case. Bronchoalveolar lavage is a major method for diagnosing tuberculosis (TB). TB dissemination caused by bronchoalveolar lavage is very rare.

Diagnostic Yield of Bronchoscopic Alveolar Lavage Gene Xpert MTB/Rif in Smear Negative Clinico-Radiologically Suspected Case of Pulmonary Tuberculosis

Journal of Nobel Medical College, 2022
Background: Early diagnosis of pulmonary tuberculosis is difficult but dreaded complications like cavitations, abscess, disseminations and fibrosis of lung parenchyma can be avoided.

The Lung Microbiome Modulates Pain‐Like Behavior Via the Lung–Brain Axis in a Nitroglycerin‐Induced Chronic Migraine Mouse Model

Advanced Science, EarlyView.
Intratracheal neomycin alters pulmonary microbiota, activating the vagus nerve via lung brain‐derived neurotrophic factor/tropomyosin receptor kinase B (BDNF/TrkB) pathway, further projecting to nucleus of solitary tract (NTS), then dorsal raphe nucleus (DRN), where activated serotoninergic neurons increase brain serotonin, alleviating migraine.

Treatment of Aspergillosis. [PDF]

, 2018
Infections caused by Aspergillus spp. remain associated with high morbidity and mortality. While mold-active antifungal prophylaxis has led to a decrease of occurrence of invasive aspergillosis (IA) in those patients most at risk for infection ...

Single‐Cell Sequencing‐Guided Annotation of Rare Tumor Cells for Deep Learning‐Based Cytopathologic Diagnosis of Early Lung Cancer

Advanced Science, EarlyView.
This study presents an innovative method to generate high‐quality, objectively annotated cytology datasets without relying on expert involvement. Large‐scale single‐cell DNA sequencing is used as an objective ground truth of cell annotation for generating an accurate, unbiased dataset of exfoliated tumor cells from bronchoalveolar lavage cytology ...

Blocking of the CD80/86 axis as a therapeutic approach to prevent progression to more severe forms of COVID-19 [PDF]

arXiv, 2020
In its more severe forms, COVID-19 progresses towards an excessive immune response, leading to the systemic overexpression of proinflammatory cytokines like IL6, mostly from the infected lungs. This cytokine storm can cause multiple organ damage and death. Consequently, there is a pressing need to identify therapies to treat and prevent severe symptoms
