Designing and developing a sensitive and specific SARS-CoV-2 RBD IgG detection kit for identifying positive human samples.

Background: More than 3 y into the coronavirus 2019 (COVID-19) pandemic, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) continues to undergo mutations. In this context, the Receptor Binding Domain (RBD) is the most antigenic region among the SARS-CoV-2 Spike protein and has emerged as a promising candidate for immunological development. We designed an IgG-based indirect enzyme-linked immunoassay (ELISA) kit based on recombinant RBD, which was produced from the laboratory to 10 L industry scales in Pichia pastoris.

GLORIA - A globally representative hyperspectral in situ dataset for optical sensing of water quality.

The development of algorithms for remote sensing of water quality (RSWQ) requires a large amount of in situ data to account for the bio-geo-optical diversity of inland and coastal waters. The GLObal Reflectance community dataset for Imaging and optical sensing of Aquatic environments (GLORIA) includes 7,572 curated hyperspectral remote sensing reflectance measurements at 1 nm intervals within the 350 to 900 nm wavelength range. In addition, at least one co-located water quality measurement of chlorophyll a, total suspended solids, absorption by dissolved substances, and Secchi depth, is provided.

"I want to focus on something that I feel really good about every day": Career development in established adulthood.

In developed countries, education and career experimentation typically extends into people's twenties (Arnett, 2000, 2015; Mehta et al., 2020). Thus, people are not committing to a career path in which they can build expertise, take on increasing responsibilities, and climb an organizational ladder (Day et al.

The effects of short interventions of focused-attention vs. self-compassion mindfulness meditation on undergraduate students: Evidence from self-report, classroom performance, and ERPs.

Mindfulness-based stress reduction (MBSR) training has been shown to improve cognitive processing, wellbeing, and academic performance. However, mindfulness interventions that are integrated into non-mindfulness related courses have not been well-investigated. Further, the unique effects of different aspects of MBSR training are not as well understood.

Playing it safe; risk-induced trait responses increase survival in the face of predation.

Predation risk effects are impacts on prey caused by predators that do not include consumption. These can include changes in prey behaviour, physiology, and morphology (i.e.

Patient Abuse in Healthcare: A Theoretical Synthesis.

Patient abuse in healthcare is an emerging phenomenon in need of explanation and further analysis. Preventing abusive incidents in healthcare requires identifying structural imbalances that make mistreatment of vulnerable individuals possible. A theory synthesis of the vicious violence triangle and the socioecological model provides a framework to investigate factors that influence nurses' abusive behavior toward patients in hospitals.

Velocity correlations in jackdaw flocks in different ecological contexts.

Velocity correlation is an important feature for animal groups performing collective motions. Previous studies have mostly focused on the velocity correlation in a single ecological context. It is unclear whether correlation characteristics vary in a single species in different contexts.

The effect of circular soil biosolarization treatment on the physiology, metabolomics, and microbiome of tomato plants under certain abiotic stresses.

Soil biosolarization (SBS) is an alternative technique for soil pest control to standard techniques such as soil fumigation and soil solarization (SS). By using both solar heating and fermentation of organic amendments, faster and more effective control of soilborne pathogens can be achieved. A circular economy may be created by using the residues of a given crop as organic amendments to biosolarize fields that produce that crop, which is termed circular soil biosolarization (CSBS).

"We Live on an Island": Perspectives on Rural Family Caregivers for Adults with Alzheimer's Disease and Related Dementias in the United States.

As the United States' aging population grows, there will be increased prevalence of individuals living with Alzheimer's Disease and related dementias (ADRD), who largely rely on the support of their family caregivers. Family caregivers residing in rural areas face additional challenges with managing caregiving responsibilities and navigating support services. The purpose of this multilevel phenomenological qualitative study was to explore the assets, unique needs, and resources of rural-residing ADRD caregivers from the caregiver, provider, and policy influencers' perspectives.

Structure of the divergent human astrovirus MLB capsid spike.

Despite their worldwide prevalence and association with human disease, the molecular bases of human astrovirus (HAstV) infection and evolution remain poorly characterized. Here, we report the structure of the capsid protein spike of the divergent HAstV MLB clade (HAstV MLB). While the structure shares a similar folding topology with that of classical-clade HAstV spikes, it is otherwise strikingly different.

Structure-Activity Relationships for Psilocybin, Baeocystin, Aeruginascin, and Related Analogues to Produce Pharmacological Effects in Mice.

4-Phosphoryloxy-,-dimethyltryptamine (psilocybin) is a naturally occurring tertiary amine found in many mushroom species. Psilocybin is a prodrug for 4-hydroxy-,-dimethyltryptamine (psilocin), which induces psychedelic effects via agonist activity at the serotonin (5-HT) 2A receptor (5-HT). Several other 4-position ring-substituted tryptamines are present in psilocybin-containing mushrooms, including the secondary amine 4-phosphoryloxy--methyltryptamine (baeocystin) and the quaternary ammonium 4-phosphoryloxy-,,-trimethyltryptamine (aeruginascin), but these compounds are not well studied.

Social and vocal complexity in bottlenose dolphins.

Bottlenose dolphins are highly social, renowned for their vocal flexibility, and possess highly enlarged brains relative to their body size. Here, we discuss some of the defining features of bottlenose dolphin social and vocal complexity and place this in the context of their cognitive evolution.

Accumulation of fluorescent advanced glycation end products and carboxymethyl-lysine in human cortical and trabecular bone.

Chemical crosslinks known as advanced glycation end-products (AGEs) are associated with increased bone fracture risk and deteriorated bone mechanical properties. However, measurement of bone AGEs via ex vivo and in vitro methods has been limited to quantification of bulk fluorescent AGEs (fAGEs) and pentosidine only, which is a crosslinking fluorescent AGE. However, a non-crosslinking and non-fluorescent AGE such as carboxymethyl-lysine (CML) is found to be 40-100 times higher in quantity than pentosidine, but only one previous study has reported it in cortical bone, and one study reported it in trabecular bone.

Coastal upwelling generates cryptic temperature refugia.

Understanding the effects of climate-mediated environmental variation on the distribution of organisms is critically important in an era of global change. We used wavelet analysis to quantify the spatiotemporal (co)variation in daily water temperature for predicting the distribution of cryptic refugia across 16 intertidal sites that were characterized as 'no', 'weak' or 'strong' upwelling and spanned 2000 km of the European Atlantic Coast. Sites experiencing weak upwelling exhibited high synchrony in temperature but low levels of co-variability at monthly to weekly timescales, whereas the opposite was true for sites experiencing strong upwelling.

Brain Age Prediction/Classification through Recurrent Deep Learning with Electroencephalogram Recordings of Seizure Subjects.

With modern population growth and an increase in the average lifespan, more patients are becoming afflicted with neurodegenerative diseases such as dementia and Alzheimer's. Patients with a history of epilepsy, drug abuse, and mental health disorders such as depression have a larger risk of developing Alzheimer's and other neurodegenerative diseases later in life. Utilizing recordings of patients' brain waves obtained from the Temple University abnormal electroencephalogram (EEG) corpus, deep leaning long short-term memory neural networks are utilized to classify and predict patients' brain ages.

Bis(oxotremorine) fumarate bis-(fumaric acid).

The title compound, bis-(oxotremorine) fumarate bis-(fumaric acid) {systematic name: 1-[4-(2-oxopyrrolidin-1-yl)but-2-yn-yl]pyrrolidinium (2)-but-2-ene-di-o-ate bis-[(2)-but-2-enedioic acid]}, 2CHNO·CHO ·2CHO, has a single oxotremorine monocation protonated at the pyrrolidine nitro-gen, one fumaric acid mol-ecule and half of a fumarate dianion in the asymmetric unit. The ions and fumaric acid mol-ecules are held together by N-H⋯O and O-H-⋯O hydrogen bonds in 40-membered rings with graph-set notation (40). The fumarate ions join these rings into infinite chains along [001].

Predator-induced transgenerational plasticity in animals: a meta-analysis.

There is growing evidence that the environment experienced by one generation can influence phenotypes in the next generation via transgenerational plasticity (TGP). One of the best-studied examples of TGP in animals is predator-induced transgenerational plasticity, whereby exposing parents to predation risk triggers changes in offspring phenotypes. Yet, there is a lack of general consensus synthesizing the predator-prey literature with existing theory pertaining to ecology and evolution of TGP.

Perceived stigma, barriers, and facilitators experienced by members of the opioid use disorder community when seeking healthcare.

Introduction: Healthcare professionals, particularly nurses, have negative attitudes towards individuals with opioid use disorder (OUD) and these attitudes can contribute to suboptimal care. The aim of this study was to identify stigma, barriers and facilitators experienced by members of the OUD community when interacting with the healthcare system.

Design: A qualitative exploratory design used semi-structured focus group interviews to address the study aim.

Highly selective fluorescent probe with an ideal pH profile for the rapid and unambiguous determination of subcellular labile iron (III) pools in human cells.

A convenient tool for detecting iron ions in subcellular structures is desired for better understanding its roles in biological systems. In this work, a new Fe sensor, 2-(2-((1-(6-acetylpyridin-2-yl)ethylidene)amino)ethyl)-3',6'-bis(diethylamino)spiro[isoindoline-1,9'-xanthen]-3-one (RhPK), which operates across the entire cellular pH range and is capable of unambiguously detecting Fe ion in live human cells at subcellular resolution, is reported. The sensor exhibits high selectivity and sensitivity toward Fe with a rapid fluorescence response and a 12-fold increase in intensity upon the addition of 1 equivalent Fe at pH 7.

Documentation Burden in Nursing and Its Role in Clinician Burnout Syndrome.

Objectives: The purpose of this study is to understand the relationship between documentation burden and clinician burnout syndrome in nurses working in direct patient care. The Office of the National Coordinator considers documentation burden a high priority problem. However, the presence of documentation burden in nurses working in direct patient care is not well known.

The methanol and ethanol solvates of 4-glutarato-,-diiso-propyl-tryptamine.

The solid-state structures of two solvated forms of 4-glutarato-,-diiso-propyl-tryptamine were determined by single-crystal X-ray diffraction, namely, 5-[(3-{2-[bis(propan-2-yl)azaniumyl]ethyl}-1-indol-4-yl)oxy]-5-oxopentanoate meth-anol monosolvate, CHNO·CHOH, and the analogous ethanol monosolvate, CHNO·CHO. In both compounds, the 4-glutarato-,-di-iso--pro-pyl-tryptamine exists as a zwitterion with a protonated tertiary ammonium and a deprotonated glutarato carboxyl-ate. The tryptamine zwitterions and alcohol solvates in both structures combine to produce near identical hydrogen-bonding networks, with N-H⋯O and O-H⋯O hydrogen bonds joining the mol-ecules together in two-dimensional networks parallel to the (100) plane.

Role of hydrogen bonding in bulk aqueous phase decomposition, complexation, and covalent hydration of pyruvic acid.

Pyruvic acid (PA) is a model for amphiphilic oxygenated organic compounds, and together with its hydrogen-bonded (H-bonded) water complexes, their presence can alter atmospheric aerosol formation. However, the fundamental understanding of PA reaction mechanisms in different environments is still being debated. Here, the role of H-bonding on PA's degradation, complexation, and covalent hydration in bulk aqueous phase is investigated theoretically.

Microcin MccI47 selectively inhibits enteric bacteria and reduces carbapenem-resistant colonization when administered an engineered live biotherapeutic.

The gastrointestinal (GI) tract is the reservoir for multidrug resistant (MDR) pathogens, specifically carbapenem-resistant (CR) and other , which often lead to the spread of antimicrobial resistance genes, severe extraintestinal infections, and lethal outcomes. Selective GI decolonization has been proposed as a new strategy for preventing transmission to other body sites and minimizing spreading to susceptible individuals. Here, we purify the to-date uncharacterized class IIb microcin I47 (MccI47) and demonstrate potent inhibition of numerous , including multidrug-resistant clinical isolates, at concentrations resembling those of commonly prescribed antibiotics.
