Background: Obstructive sleep apnea (OSA) and chronic obstructive pulmonary disease (COPD) are associated with unfavorable outcomes following coronary artery bypass grafting (CABG). The purpose of this study was to compare in-hospital outcomes of patients with COPD alone versus OSA-COPD overlap after CABG.

Methods: Data of adults ≥ 18 years old with COPD who received elective CABG between 2005 and 2018 were extracted from the US Nationwide Inpatient Sample (NIS).

The small RNAs on living cell membranes were recently found to be -glycosylated and terminated with sialic acids, although the glycosylation sites and potential functions remain unclear. Herein, we designed a second-generation hierarchical coding strategy (HieCo 2) for in situ visualization of cell surface RNA-specific sialylation. After covalently binding DNA codes to sialic acids and then binding a DNA code to a target RNA via sequence specificity, cascade decoding processes were performed with subsequent signal amplification that enabled sensitive in situ visualization of low-abundance Y5 RNA-specific sialic acids on living cell membranes.

Glycan oxidation on the cell surface occurs in many specific life processes including pathogen-cell interactions. This work develops a surface-enhanced Raman scattering (SERS) imaging strategy for quantitative monitoring of protein-specific glycan oxidation mediated pathogen-cell interactions by utilizing Raman reporter DTNB and aptamer co-assembled platinum shelled gold nanoparticles (Au@Pt-DTNB/Apt). Using () and MCF-7 cells as models, Au@Pt-DTNB/Apt can specifically bind to MUC1 protein on the cell surface containing heavy galactose (Gal) and -acetylgalactosamine (GalNAc) modification.

Albumin-manganese-based nanocomposites (AMNs) characterized by simple preparation and good biocompatibility have been widely used for -weighted magnetic resonance imaging (MRI) and cancer theranostics. Herein, an aggregation and crosslinking assembly strategy was proposed to achieve the sensitization to relaxivity of the albumin-manganese nanocomposite. At a relatively low Mn content (0.

With multiple emissions ranging from NIR-IIb to visible lights, near-infrared light-excited lanthanide nanoparticle (LnNP) is an ideal in-vivo theranostic platform to achieve imaging guided phototherapy. However, current reported LnNPs typically demonstrate simultaneous up and downconversion emissions with fixed single excitation light, which impairs therapeutic efficiency and generates side effect during navigation. Here we develop a lanthanide-based conversion switching nanoparticle (CSNP) with independent activation of 1550 nm NIR-IIb downconversion emission under 808 nm excitation and 345/450 nm upconversion emission under 980 nm excitation.

-GlcNAcylation is involved in many biological processes including cancerization. Nevertheless, its quantification in single living cells is still a bottleneck. Here we develop a quantitative SERS imaging strategy for mapping the -GlcNAcylation distribution of single living cells.

Sialylation plays an important role in tumor-related physiological processes. Therefore, intervention of sialylation has great potential to explore new paths for tumor therapy. In view of the immune modulation of sialic acid (SA) on tumors, this work designs a multifunctional mesoporous silica nanoparticle (MFMSN) to divert intracellular sialylation for tumor suppression.

Protein-membrane interactions play important roles in signal transductions and functional regulation of membrane proteins. Here, we design a molecular dynamometer (MDM) for analyzing protein-membrane interaction on living cells. The MDM is constructed by assembling an artificial lipid bilayer and alkylated Cy3-DNA azide (azide-Cy3-C) on a silica bubble.

The plasma membrane repair holds significance for maintaining cell survival and homeostasis. To achieve the sensitive visualization of membrane repair process for revealing its mechanism, this work designs a perforation-induced surface-enhanced Raman spectroscopy (SERS) strategy by conjugating Raman reporter (4-mercaptobenzoic acid) loaded gold nanostars with pore-forming protein streptolysin O (SLO) to induce the SERS signal on living cells. The SERS signal obviously decreases with the initiation of membrane repair and the degradation of SLO pores due to the departure of gold-nanostar-conjugated SLO.

Background: Phyllodes tumors (PTs) are well known for local recurrence and progression. Less than 10% of these tumors grow larger than 10 cm. Distant metastases have been reported in up to 22% of malignant PTs, with most metastases being discovered in the lungs.

A functional dual-color indicator is designed for in situ visualization of intracellular glycosylation. Using O-GlcNAcylation as model, the indicator is constructed on a poly-GlcNAc-coated gold nanoparticle (AuNP) by assembling dye labeled lectin (FSWGA) and then another dye-labeled GlcNAc (FGlcNAc) through the two opposite subunits of FSWGA. These dyes possess negligible overlapping emission and can be quenched by AuNP.

A screening strategy involving designed extractors and collectors was used for the nondestructive quantitation of gangliosides on cell surfaces. The extractors were constructed by functionalizing maleimide silica bubbles with a DNA probe, which contains an endonuclease cleavage site and a boronic acid end to extract cell-surface sialic acid-containing compounds through simple centrifugation. After the extractors containing the extracted compounds were incubated with endonuclease, the released oligonucleotide-gangliosides were selectively collected by silanized collector bubbles through hydrophobic interactions.

Background: Adrenal myelolipoma is an uncommon, benign, and hormonally non-functioning tumor that is composed of mature adipose tissue and normal hematopoietic tissue. Most cases to date are asymptomatic or have epigastric pain. Acute hemorrhage is the most dramatic manifestation of adrenal myelolipoma; though, it is a rare entity.
