Protein-protein interactions between virus and host are crucial for infection. SARS-CoV-2, the causative agent of COVID-19 pandemic is an RNA virus prone to mutations. Formation of a stable binding interface between the Spike (S) protein Receptor Binding Domain (RBD) of SARS-CoV-2 and Angiotensin-Converting Enzyme 2 (ACE2) of host actuates viral entry. Yet, how this binding interface evolves as virus acquires mutations during pandemic remains elusive. Here, using a high fidelity bioinformatics pipeline,...

The aim of this study was to predict the angiographic occlusion status after flow-diverter treatment with computational fluid dynamics using porous media modeling for decision-making in the treatment of large wide-neck aneurysms.MATERIALS AND METHODS:A total of 27 patients treated with flow-diverter stents were retrospectively analyzed through computational fluid dynamics using pretreatment patient-specific...
SUMMARY:"Asleep" deep brain stimulation using general anesthesia and intraoperative MR imaging guidance is considered "off-label" use by current FDA guidelines but is widely used in neurosurgical practice, and excellent safety has been demonstrated using first-generation, omnidirectional electrodes. Safety data for second-generation, directional electrodes in the interventional MR imaging environment have not yet been published. Herein, we report 34 cases of asleep deep brain stimulation using second-generation,...
BACKGROUND AND PURPOSE:Infarct core volume measurement using CTP (CT perfusion) is a mainstay paradigm for stroke treatment decision-making. Yet, there are several downfalls with cine CTP technology that can be overcome by adopting the simple perfusion reconstruction algorithm (SPIRAL) derived from multiphase CTA. We compare SPIRAL with CTP parameters for the prediction of 24-hour infarction.MATERIALS AND METHODS:Seventy-two patients had admission NCCT, multiphase CTA, CTP, and 24-hour DWI. All patients...
BACKGROUND AND PURPOSE:Treatment of dural arteriovenous fistulas can be performed by transarterial or transvenous accesses. For those fistulas located at a dural sinus wall, obliteration of the sinus might lead to a substantial risk of complications if the occluded sinus impairs normal venous drainage. For those fistulas with direct leptomeningeal venous drainage, navigation to reach the arteriovenous shunting point of a leptomeningeal vein is usually technically demanding. We report the outcomes...
BACKGROUND AND PURPOSE:Detailed arterial anatomy of the sphenoid ridge and olfactory groove meningiomas is complicated due to the fine angioarchitecture and anastomoses between each feeder.

The banana aphid, Pentalonia nigronervosa Coquerel (Hemiptera: Aphididae), is a major pest of cultivated bananas (Musa spp., order Zingiberales), primarily due to its role as a vector of Banana bunchy top virus (BBTV), the most severe viral disease of banana worldwide. Here, we generated a highly complete genome assembly of P. nigronervosa using a single PCR-free Illumina sequencing library. Using the same sequence data, we also generated complete genome assemblies of the P. nigronervosa symbiotic...
Abstract Rationale Schizophrenia is a devastating mental disease that affects nearly 1% of the population worldwide. It is well documented that the dopaminergic (DAergic) system is compromised in schizophrenia. It is of note that the mixed dopamine (DA) D1/D2 receptor agonist apomorphine induces schizophrenia-like symptoms in rodents, including disruption of memory abilities. Neuroactive steroids, comprising dehydroepiandrosterone (DHEA)...

Background: The nucleotide composition of the genome is a balance between origin and fixation rates of different mutations. For example, it is well-known that transitions occur more frequently than transversions, particularly at CpG sites. Differences in fixation rates of mutation types are less explored. Specifically, recombination-associated GC-biased gene conversion (gBGC) may differentially impact GC-changing mutations, due to differences in their genomic distributions and efficiency of mismatch...

Many bones in the vertebrate skeleton, including the limb bones, axial skeleton, and bones of the floor of the cranium, grow through the process of endochondral ossification, under the control of growth plates. The cellular and molecular mechanisms of endochondral ossification are conserved across these cartilaginous growth plates, increasing the tendency of skeletal elements to covary in size and shape. Covariation at the phenotypic, developmental, and genetic levels has been hypothesized to lead...

Abstract Programmable transcriptional regulation is a powerful tool to study gene functions. Current methods to selectively regulate target genes are mainly based on promoter exchange or on overexpressing transcriptional activators. To expand the discovery toolbox, we designed a dCas9-based RNA-guided synthetic transcription activation system for Aspergillus nidulans that uses enzymatically disabled “dead” Cas9 fused to three consecutive activation domains...
To the Editor: The standard care for chronic spontaneous urticaria includes second-generation H1-antihistamines, but such treatment is often ineffective, even with four times the dose recommended by the Food and Drug Administration. Urticarial lesions are characterized pathologically by increased…

Background Patients diagnosed with sarcoma are hypothesized to experience a prolonged route to a cancer diagnosis. This route, the total interval, can be divided into a patient interval (the time from the appearance of symptoms to physician consultation) and diagnostic interval (time from the first consultation to diagnosis). In the current study, the authors investigated these intervals among survivors of sarcoma and identified factors associated with prolonged intervals. Methods A cross‐sectional...
Background Surgeons play a pivotal role in combating the opioid crisis that currently grips the United States. Changing surgeon behavior is difficult, and the degree to which behavioral science can steer surgeons toward decreased opioid prescribing is unclear. Methods This was a single‐institution, single‐arm, pre‐ and postintervention study examining the prescribing of opioids by urologists for adult patients undergoing prostatectomy or nephrectomy. The primary outcome was the quantity of...
Chronic Respiratory Disease, Volume 17, Issue , January-December 2020. Introduction:The COVID pandemic has had a high psychological impact on healthy populations. Increased levels of perceived stress, depression, and insomnia are expected, especially in people with pre-existing medical conditions, such as asthma and chronic obstructive pulmonary disease (COPD), who seem to be particularly vulnerable. However, the difference in psychological distress frequency between asthma and COPD patients is unknown.Objective:To...
Chronic Respiratory Disease, Volume 17, Issue , January-December 2020. The spread of the SARS-CoV-2 infection among population has imposed a re-organization of healthcare services, aiming at stratifying patients and dedicating specific areas where patients with suspected COVID-related respiratory disease could receive the necessary health care assistance while waiting for the confirmation of the diagnosis of COVID-19 disease. In this scenario, the pathway defined as a “grey zone” is strongly advocated....
Optical clearing skull window is a novel technique compared to the traditional surgery based cranial window, which could reduce the scattering of skull and make it transparent to visible light. Here, the NIR‐II optimized skull clearing window was established. In the application of NIR‐II excited THG microscopy, the imaging depth was more than 3 times as it without optical clearing, and close to it with the open‐skull window. In addition, the established skull optical clearing window promises to...
Optical Coherence Tomography angiography (OCTA) is widely used to image chorioretinal vasculature, with contrast that derives from scattering and motion of red blood cells (RBCs). In the rat eye, a scattering tracer highlights vertical vessels which are not visualized by intrinsic RBC scattering alone. The dependence of microvessel OCTA on angular orientation, explored in this work, represents a potential artifact that should be considered in the clinical interpretation of OCTA. Further details...

Further details can be found in the article by Hsiao‐Huang Chang, Yi‐Chih Chen, Chun‐Jung Huang, Chia‐Cheng...
Low-dose aspirin is recommended by the U.S. Preventive Services Task Force for primary prevention of colorectal cancer in certain individuals. However, broader implementation will require improved precision prevention approaches to identify those most likely to benefit. The major urinary metabolite of PGE2, 11α-hydroxy-9,15-dioxo-2,3,4,5-tetranor-prostane-1,20-dioic acid (PGE-M), is a biomarker for colorectal cancer risk, but it is unknown whether PGE-M is modifiable by aspirin in individuals at...
Given that high-risk human papillomavirus (HPV) is the necessary cause of virtually all cervical cancer, the clinical meaning of HPV-negative cervical precancer is unknown. We, therefore, conducted a literature search in Ovid MEDLINE, PubMed Central, and Google Scholar to identify English-language studies in which (i) HPV-negative and -positive, histologically confirmed cervical intraepithelial neoplasia grade 2 or more severe diagnoses (CIN2+) were detected and (ii) summarized statistics or deidentified...
Aspirin and statin use may lower the risk of advanced/fatal prostate cancer, possibly by reducing intraprostatic inflammation. To test this hypothesis, we investigated the association of aspirin and statin use with the presence and extent of intraprostatic inflammation, and the abundance of specific immune cell types, in benign prostate tissue from a subset of men from the placebo arm of the Prostate Cancer Prevention Trial. Men were classified as aspirin or statin users if they reported use at baseline...
Obesity and obesity-driven cancer rates are continuing to rise worldwide. We hypothesize that adipocyte–colonocyte interactions are a key driver of obesity-associated cancers. To understand the clinical relevance of visceral adipose tissue in advancing tumor growth, we analyzed paired tumor-adjacent visceral adipose, normal mucosa, and colorectal tumor tissues as well as presurgery blood samples from patients with sporadic colorectal cancer. We report that high peroxisome proliferator-activated receptor...
Obesity is the second leading environmental association with cancer risk; yet, the mechanisms by which obesity drives carcinogenesis are poorly understood. The paper published in this issue of Cancer Prevention Research by Holowatyj and colleagues explores the mechanisms of human visceral adipose–epithelial signaling using samples collected at surgery in patients with invasive colorectal cancer. They identify pathway intermediates potentially involved in the regulation of fibrosis, inflammation,...
The Women's Health Initiative (WHI) was designed to evaluate the benefits of hormone replacement therapy. The primary goal was to establish the value of synthetic progestin and estrogen or estrogen alone to reduce the risk of coronary heart disease (CHD). The estrogen/synthetic progestin trial was stopped at 5.2 years and the estrogen trial was stopped after 6.8 years. Although the estrogen/synthetic progestin trial was stopped for the anticipated rise in the risk of breast cancer, the estrogen trial...
Prostate cancer is common in countries with affluent dietary patterns and represents a heterogeneous collection of subtypes with varying behavior. Reductionist strategies focusing on individual nutrients or foods have not clearly defined risk factors. We have developed mechanisms-based dietary patterns focusing upon inflammation and chronic insulin hypersecretion, processes that are hypothesized to impact prostate carcinogenesis. In the Prostate, Lung, Colorectal, and Ovarian cancer cohort, we calculated...
Although substantial evidence supports aspirin's efficacy in colorectal cancer chemoprevention, key molecular mechanisms are uncertain. An untargeted metabolomics approach with high-resolution mass spectrometry was used to elucidate metabolic effects of aspirin treatment in human colon tissue. We measured 10,269 metabolic features in normal mucosal biopsies collected at colonoscopy after approximately 3 years of randomized treatment with placebo, 81 or 325 mg/day aspirin from 325 participants in...
