Breadth and function of antibody response to acute SARS-CoV-2 infection in humans.

Serological and plasmablast responses and plasmablast-derived IgG monoclonal antibodies (MAbs) have been analysed in three COVID-19 patients with different clinical severities. Potent humoral responses were detected within 3 weeks of onset of illness in all patients and the serological titre was elicited soon after or concomitantly with peripheral plasmablast response. An average of 13.

Systematic evaluation of multiple qPCR platforms, NanoString and miRNA-Seq for microRNA biomarker discovery in human biofluids.

Aberrant miRNA expression has been associated with many diseases, and extracellular miRNAs that circulate in the bloodstream are remarkably stable. Recently, there has been growing interest in identifying cell-free circulating miRNAs that can serve as non-invasive biomarkers for early detection of disease or selection of treatment options. However, quantifying miRNA levels in biofluids is technically challenging due to their low abundance.

Stressful life events, depression, and the moderating role of psychophysiological reactivity in patients with pediatric inflammatory bowel disease.

Objective: The development of depressive symptoms in youth with IBD is a concerning disease complication, as higher levels of depressive symptoms have been associated with poorer quality of life and lower medication adherence. Previous research has examined the association between disease activity and depression, but few studies have examined individual differences in experience of stressful life events in relation to depressive symptoms. The purpose of the current study is to examine the relation between stressful life events and depression within pediatric IBD and to determine whether individual differences in stress response moderates this association.

Temperament and Health-Related Quality of Life in Newly Diagnosed Pediatric Inflammatory Bowel Disease.

Objective: Health-related quality of life (HRQOL) is typically examined from a deficit standpoint, meaning that little is known about factors associated with higher HRQOL in pediatric illness samples. The aim of the current study was to investigate demographic, disease, and temperamental factors associated with child and parent-report of HRQOL in youth newly diagnosed with inflammatory bowel disease (IBD).

Methods: Participants included 52 youth ages 8-17 diagnosed with IBD and their caregivers who each completed ratings of the child's HRQOL.

Is microfluidics the "assembly line" for CRISPR-Cas9 gene-editing?

Acclaimed as one of the biggest scientific breakthroughs, the technology of CRISPR has brought significant improvement in the biotechnological spectrum-from editing genetic defects in diseases for gene therapy to modifying organisms for the production of biofuels. Since its inception, the CRISPR-Cas9 system has become easier and more versatile to use. Many variants have been found, giving the CRISPR toolkit a great range that includes the activation and repression of genes aside from the previously known knockout and knockin of genes.

Nonpolio Enterovirus Activity during the COVID-19 Pandemic, Taiwan, 2020.

In Taiwan, lower nonpolio enterovirus activity during the coronavirus disease pandemic in 2020 compared with 2014-2019 might be attributable to adherence to nonpharmaceutical interventions. The preventable fraction among unexposed persons indicated that 90% of nonpolio enterovirus activity might have been prevented during 2014-2019 by adopting the same measures enforced in 2020.

Comprehensive Transcriptomic Analysis Identifies as a Survival-Related Sialyltransferase Gene in Breast Cancer.

Hypersialylation caused by the overexpression of sialyltransferases (STs) is a common feature in cancer that is associated with several characteristics of tumorigenesis. Thus, identifying cancer-associated STs is critical for cancer therapy. However, ST screening has been frequently conducted in cell line models.

Oxidative stress mediates age-related hypertrophy of ligamentum flavum by inducing inflammation, fibrosis, and apoptosis through activating Akt and MAPK pathways.

The role of oxidative stress in ligamentum flavum (LF) hypertrophy has not been elucidated. We hypothesize that oxidative stress induces inflammatory responses and the subsequent fibrotic processes in LF, via activation of the Akt and MAPK pathways. Specimens of LFs were collected during surgeries for lumbar disc herniation (LDH) or lumbar spinal stenosis (LSS).

Reproductive potential does not cause loss of heat shock response performance in honey bees.

In other species characterized to date, aging, as a function of reproductive potential, results in the breakdown of proteaostasis and a decreased capacity to mount responses by the heat shock response (HSR) and other proteostatic network pathways. Our understanding of the maintenance of stress pathways, such as the HSR, in honey bees, and in the reproductive queen in particular, is incomplete. Based on the findings in other species showing an inverse relationship between reproductive potential and HSR function, one might predict that that HSR function would be lost in the reproductive queens.

Effect of a Neuropilin-1-Derived Virus Receptor Trap on Enterovirus A71 Infection .

We discovered that neuropilin 1 (NRP1) is a new receptor candidate to mediate enterovirus A71 (EVA71) into cells. In the engineered form as a decoy receptor, NRP1 was able to recognize and neutralize EVA71 but not enterovirus D68 or coxsackievirus B3 (CVB3). NRP1 recognizes EVA71 through a novel domain on the VP3 capsid protein.

A Strategy to Treat COVID-19 Disease With Targeted Delivery of Inhalable Liposomal Hydroxychloroquine: A Preclinical Pharmacokinetic Study.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a newly identified pathogen causing the coronavirus disease 2019 (COVID-19) pandemic. Hydroxychloroquine (HCQ), an antimalarial and anti-inflammatory drug, has been shown to inhibit SARS-CoV-2 infection in vitro and tested in clinical studies. However, achievement of lung concentrations predicted to have in vivo antiviral efficacy might not be possible with the currently proposed oral dosing regimens.

An Examination of Parent-Reported Facilitators and Barriers to Organized Physical Activity Engagement for Youth With Neurodevelopmental Disorders, Physical, and Medical Conditions.

Organized physical activity (OPA) is an important contributor to physical, social, and emotional health and well-being; however, young people with disabilities are participating at lower rates than their peers without disabilities. This study aimed to (1) compare facilitators and barriers to OPA for young people with disabilities who currently do and do not participate in OPA and (2) to assess whether groups differed in the type of internal and external assets they reported. Parents of 218 young people (41% with a primary diagnosis of autism spectrum disorder) with a diverse representation of disabilities completed an online survey.

The Inverse Care Law might not apply to preventative health services in community pharmacy.

Introduction: The Inverse Care Law states that healthcare availability is inversely related to the needs of the population served. Increasing the provision of community pharmacy (CP) services for cardiovascular disease has been suggested to improve equity of healthcare access, particularly for screening, but few studies examine this. The aim of this study was to determine how the availability and uptake of cardiovascular disease (CVD) prevention services in CPs varies according to practice and local population characteristics.

Parent and Family Functioning in Pediatric Inflammatory Bowel Disease.

Although the impact of pediatric inflammatory bowel disease (IBD) extends beyond the patient to their parents and families, the focus of previous literature has largely been on investigating the patient's medical and psychosocial functioning, with less consideration of the family system. Having a comprehensive understanding of parent and family functioning within the context of pediatric IBD is important given the role parents and family members have in the successful management of the disease and caring of the child. The current review paper aggregates the empirical research regarding parent and family functioning, including comparisons to normative samples, other illness groups, and how functioning relates to child psychosocial and health outcomes.
