Lung injury is characterized by diffuse lung inflammation, alveolar-capillary destruction, and alveolar flooding, resulting in respiratory failure. Polydexyribonucleotide (PDRN) has an anti-inflammatory effect, decreasing inflammatory cytokines, and suppressing apoptosis. Thus, we investigated its efficacy in the treatment of lung injury, which was induced in rats using lipopolysaccharide (LPS). Rats were randomly divided into three groups according to sacrifice time, and each group split into c

Image reconstruction in fluorescence diffuse optical tomography (FDOT) is a highly ill-posed inverse problem due to a large number of unknowns and limited measurements. In FDOT, the fluorophore distribution is often sparse in the imaging domain, since most fluorophores are designed to accumulate in relatively small regions. Compressive sensing theory has shown that sparse signals can be recovered exactly from only a small number of measurements when the forward sensing matrix is sufficiently inc

Fluorescence diffuse optical tomography (FDOT) is an emerging molecular imaging modality that uses near infrared light to excite the fluorophore injected into tissue; and to reconstruct the fluorophore concentration from boundary measurements. The FDOT image reconstruction is a highly ill-posed inverse problem due to a large number of unknowns and limited number of measurements. However, the fluorophore distribution is often very sparse in the imaging domain since fluorophores are typically desi

High Resolution Image Download MS PowerPoint Slide In this study, graphene oxide (GO) was modified via electrostatic interactions and chemical grafting by silica (SiO 2 ), and two SiO 2 @GO hybrids (GO-A and GO-B, respectively) with different structures were obtained and carefully characterized. Results confirmed the successful grafting of SiO 2 onto the GO surface using both strategies. The distribution of SiO 2 particles on the surface of GO-A was denser and more agglomerated, while it was mor

The current phytochemical investigations revealed that coumarins and flavones represent the primary chemical constituents of F. erecta. Compounds 7 and 17 exhibit potent anti-inflammatory properties, linked with the inhibition of NF-κB activation by preventing the degradation of IκBα phosphorylation. These compounds may serve as promising candidates for treating or preventing certain inflammatory diseases.

The bronchial microbiome of patients with asthma differs from that of the healthy controls. Metagenomic analysis has been conducted using 16S recombinant DNA sequencing from extracellular vesicles (EVs) to identify microbiomes and provide culture-independent estimation of microbial diversity.1Lee J.H.

The incidence of pulmonary tuberculosis has been reducing, but endobronchial tuberculosis continues to be a signigicant heath problem. We performed prospectively bronchoscopy in patients diagnosed with pulmonary tuberculosis in order to evaluate the frequency of endobronchial tuberculosis and its related findings. Follow-up bronchoscopy was also performed after treatment to evaluate the incidence of endobronchial complications such as stenosis and remaining lesions. Methods : From January , 1999

Sunflower seeds (Helianthus annuus) are an uncommon source of allergy; however, some cases of allergy to sunflower seeds have been reported. Sunflower seed sensitization occurs to storage proteins (2S albumins) and lipid transfer proteins (LTPs). A 46-year-old female presented three allergic reactions within minutes of consuming sunflower seeds. A prick-to-prick test indicated a positive reaction only to sunflower seeds and a negative reaction to other nuts, such as almond, hazelnut, pistachio,
