IL-1β-driven NF-κB transcription of ACE2 as a Mechanism of Macrophage Infection by SARS-CoV-2.

Coronavirus disease 2019 (COVID-19), caused by infection with the enveloped RNA betacoronavirus, SARS-CoV-2, led to a global pandemic involving over 7 million deaths. Macrophage inflammatory responses impact COVID-19 severity; however, it is unclear whether macrophages are infected by SARS-CoV-2. We sought to identify mechanisms regulating macrophage expression of ACE2, the primary receptor for SARS-CoV-2, and to determine if macrophages are susceptible to productive infection.

Memory Reactivation during Sleep Does Not Act Holistically on Object Memory.

Memory reactivation during sleep is thought to facilitate memory consolidation. Most sleep reactivation research has examined how reactivation of specific facts, objects, and associations benefits their overall retention. However, our memories are not unitary, and not all features of a memory persist in tandem over time.

Standardization of urinary tract infection diagnosis in the neonatal ICU: Experience at a tertiary care center.

Background: Urinary tract infections (UTIs) and antibiotic overexposure are common neonatal problems. Recently, evidence has emerged that a standardized approach to neonatal UTI can reduce unnecessary diagnosis without complications.

Mitochondrial Deoxyribonucleic Acid (mtDNA), Maternal Inheritance, and Their Role in the Development of Cancers: A Scoping Review.

Mitochondrial DNA (mtDNA) is a small, circular, double-stranded DNA inherited from the mother during fertilization. Evolutionary evidence supported by the endosymbiotic theory identifies mitochondria as an organelle that could have descended from prokaryotes. This may be the reason for the independent function and inheritance pattern shown by mtDNA.

Incremental prognostic value of echocardiographic strain and its association with mortality in cancer patients.

Background: Left ventricular global longitudinal systolic strain (GLS) has been shown to be superior to ejection fraction in detecting subclinical dysfunction in patients with cancer and predicting mortality in patients with cardiovascular disease. Cancer-related fatigue is common in the later stages of neoplastic malignancies and may be indicative of nonovert heart failure. The aim of this study was to determine whether reduced strain by echocardiography was associated with all-cause mortality in a cancer cohort.

Parallel optical nanolithography using nanoscale bowtie aperture array.

We report results of parallel optical nanolithography using nanoscale bowtie aperture array. These nanoscale bowtie aperture arrays are used to focus a laser beam into multiple nanoscale light spots for parallel nano-lithography. Our work employed a frequency-tripled diode-pumped solid state (DPSS) laser (lambda = 355 nm) and Shipley S1805 photoresist.

Three-dimensional mapping of optical near field of a nanoscale bowtie antenna.

Ridge nanoscale aperture antennas have been shown to be a high transmission nanoscale light source. They provide a small, polarization-dependent near-field optical spot with much higher transmission efficiency than circularly-shaped apertures with similar field confinement. This provides significant motivations to understand the electromagnetic fields in the immediate proximity to the apertures.

The role of continuous positive airway pressure in the treatment of hypertension in patients with obstructive sleep apnea-hypoapnea syndrome: a review of randomized trials.

Obstructive sleep apnea-hypoapnea syndrome (OSA) is a disorder that results in repetitive occlusion of the airway and hypoxemia during sleep. Epidemiologic studies have associated this disorder with increased cardiovascular morbidity and mortality. Systemic hypertension is prevalent among patients with OSA and has been recognized as a common identifiable cause of hypertension.

High-density biatrial pacing protects against atrial fibrillation by synchronizing left atrial tissue.

Purpose: The induction and sustainability of atrial fibrillation (AF) are most commonly due to pulmonary vein (PV) triggers and left atrial (LA) substrate. We hypothesized that simultaneous pacing of the PV ostia, LA, and right atrium (RA) reduces AF susceptibility by synchronizing atrial activity.

Methods: Mongrel dogs were rapidly paced and maintained in AF for 3 months before cardioversion.

Baroreflex device therapy in the treatment of hypertension.

Despite therapy with multiple optimally dosed medications, hypertension remains poorly controlled in a sizeable number of people worldwide. This has spurred interest in exploring other pharmacologic and nonpharmacologic options for treatment. The carotid baroreceptors are important in regulating blood pressure in chronic hypertension by centrally mediated sympathoinhibitory effects and other effects.

Nanopatterning using NSOM probes integrated with high transmission nanoscale bowtie aperture.

Nanoscale ridge aperture antennas have been shown to have high transmission efficiency and confined nanoscale radiation in the near field region compared with regularly-shaped apertures. The radiation enhancement is attributed to the fundamental electric-magnetic field propagating in the TE(10) mode concentrated in the gap between the ridges. This paper reports experimental demonstration of field enhancement using such ridge antenna apertures in a bowtie shape for the manufacture of nanometer size structures using an NSOM (near field scanning optical microscopy) probe integrated with nanoscale bowtie aperture.
