Views From State-Level Policy Actors About the US Federal Government COVID-19 Response.

The United States takes a federalist approach to pandemic responses while the bulk of pandemic powers sits at the state level. Thus, comprehensive accounts of how state health officials managed the crisis and how the federal government affected those efforts are needed to better understand the governmental response to the COVID-19 pandemic. This article reports the results of semistructured interviews with 29 state-level policy actors from 16 US states.

Alterations in care for children with special healthcare needs during the early COVID-19 pandemic: ethical and policy considerations.

Healthcare delivery and access, both in the United States and globally, were negatively affected during the entirety of the COVID-19 pandemic. This was particularly true during the first year when countries grappled with high rates of illness and implemented non-pharmaceutical interventions such as stay-at-home orders. Among children with special healthcare needs, research from the United Kingdom (U.

Behavioural responses of to standard pyrethroid and PBO-treated bednets of different operational ages.

To combat pyrethroid insecticide resistance, there has been widespread distribution of pyrethroid-treated bednets (ITNs) co-impregnated with piperonyl butoxide (PBO), a synergist that inhibits enzyme activity to block metabolic resistance. While PBO impacts physiological resistance, mosquito behavioural responses when attempting to blood-feed through nets may be more dependent on net characteristics, in particular the insecticide treatment and operational age of nets. These potentially interacting effects are currently not well characterised.

"Lives versus livelihoods": Conflict and coherence between policy objectives in the COVID-19 pandemic.

Many policies were put in place during the COVID-19 pandemic in the United States to manage the negative impact of the coronavirus. Limiting severe illness and death was one important objective of these policies, but it is widely acknowledged by public health ethicists that pandemic policies needed to consider other factors. Drawing on semi-structured interviews with 38 people across 17 states who participated in the state-level COVID-19 pandemic policy process, we examine how those actors recounted their engagement with four different objectives over the course of the pandemic: protecting public health with respect to COVID-19 (which we refer to as pathogen-focused disease prevention), protecting the economy, promoting the public's broader health and wellbeing, and preserving and restoring individual freedoms.

Increasing Proteome Coverage Through a Reduction in Analyte Complexity in Single-Cell Equivalent Samples.

The advancement of sophisticated instrumentation in mass spectrometry has catalyzed an in-depth exploration of complex proteomes. This exploration necessitates a nuanced balance in experimental design, particularly between quantitative precision and the enumeration of analytes detected. In bottom-up proteomics, a key challenge is that oversampling of abundant proteins can adversely affect the identification of a diverse array of unique proteins.

Disruption of Circadian Clock Induces Abnormal Mammary Morphology and Aggressive Basal Tumorigenesis by Enhancing LILRB4 Signaling.

Epidemiological studies have shown that circadian rhythm disruption (CRD) is associated with the risk of breast cancer. However, the role of CRD in mammary gland morphology and aggressive basal mammary tumorigenesis and the molecular mechanisms underlying CRD and cancer risk remain unknown. To investigate the effect of CRD on aggressive tumorigenesis, a genetically engineered mouse model that recapitulates the human basal type of breast cancer was used for this study.

'Staying in the lane' of public health? Boundary-work in the roles of state health officials and experts in COVID-19 policymaking.

The state-level COVID-19 response in the United States necessitated collaboration between governor' offices, health departments and numerous other departments and outside experts. To gain insight into how health officials and experts contributed to advising on COVID-19 policies, we conducted semi-structured interviews with 25 individuals with a health specialisation who were involved in COVID-19 policymaking, taking place between February and December 2022. We found two diverging understandings of the role of health officials and experts in COVID-19 policymaking: the role of 'staying in the lane' of public health in terms of the information that they collected, their advocacy for policies and their area of expertise and the role of engaging in the balancing of multiple considerations, such as public health, feasibility and competing objectives (such as the economy) in the crafting of pandemic policy.

Video augmentation of the WHO cone assay to quantify mosquito behavioural responses to insecticide-treated nets.

Background: Insecticide-treated nets (ITNs) using pyrethroids have been the main vector control tools deployed in malaria endemic countries and are responsible for the dramatic reduction in African malaria cases in the early 2000s. The World Health Organization (WHO) cone test was designed to assess the rapid toxicity effects of pyrethroid exposure on mosquito vectors but has yielded no insights beyond 60-min knockdown and 24-h mortality. As dual-active-ingredient (AI) ITNs become more widespread, bioassays that can provide realistic assessment of single- and dual-treated ITNs (i.

Acquired resistance to KRAS G12C small-molecule inhibitors via genetic/nongenetic mechanisms in lung cancer.

Inherent or acquired resistance to sotorasib poses a substantialt challenge for NSCLC treatment. Here, we demonstrate that acquired resistance to sotorasib in isogenic cells correlated with increased expression of integrin β4 (ITGB4), a component of the focal adhesion complex. Silencing ITGB4 in tolerant cells improved sotorasib sensitivity, while overexpressing ITGB4 enhanced tolerance to sotorasib by supporting AKT-mTOR bypass signaling.

Mapping indoor resting behavior reveals a preference vulnerable to householder-led vector control.

Many mosquito vectors rest inside human habitations, a behavioral trait that is exploited for vector control by indoor residual spraying (IRS) of interior walls with insecticide. Although IRS and its refined version targeted IRS are very effective against , they are expensive and logistically challenging to deliver in densely populated urban areas where outbreaks of dengue and other arboviruses are the greatest challenge. In experiments in Recife, Brazil, we set out to quantify the indoor resting behavior of at a level beyond that previously reported.

Tidyproteomics: an open-source R package and data object for quantitative proteomics post analysis and visualization.

Background: The analysis of mass spectrometry-based quantitative proteomics data can be challenging given the variety of established analysis platforms, the differences in reporting formats, and a general lack of approachable standardized post-processing analyses such as sample group statistics, quantitative variation and even data filtering. We developed tidyproteomics to facilitate basic analysis, improve data interoperability and potentially ease the integration of new processing algorithms, mainly through the use of a simplified data-object.

Results: The R package tidyproteomics was developed as both a framework for standardizing quantitative proteomics data and a platform for analysis workflows, containing discrete functions that can be connected end-to-end, thus making it easier to define complex analyses by breaking them into small stepwise units.

Inputs and Outputs of the Mammalian Circadian Clock.

Circadian rhythms in mammals are coordinated by the central circadian pacemaker, the suprachiasmatic nucleus (SCN). Light and other environmental inputs change the timing of the SCN neural network oscillator, which, in turn, sends output signals that entrain daily behavioral and physiological rhythms. While much is known about the molecular, neuronal, and network properties of the SCN itself, the circuits linking the outside world to the SCN and the SCN to rhythmic outputs are understudied.

The Widening Gap between the Digital Capability of the Care Workforce and Technology-Enabled Healthcare Delivery: A Nursing and Allied Health Analysis.

There is a need to ensure that healthcare organisations enable their workforces to use digital methods in service delivery. This study aimed to evaluate the current level of digital understanding and ability in nursing, midwifery, and allied health workforces and identify some of the training requirements to improve digital literacy in these health professionals. Representatives from eight healthcare organizations in Victoria, Australia participated in focus groups.

From Housewives to Employees, the Mental Benefits of Employment across Women with Different Gender Role Attitudes and Parenthood Status.

Previous studies suggest that paid employment can improve workers' mental health status by offering a series of manifest and latent benefits (i.e., income, self-achievement and social engagement), which motivates policymakers' ongoing promotion of labour force participation as an approach to protect women's mental health status.

Mechanisms of chlorate toxicity and resistance in Pseudomonas aeruginosa.

Pseudomonas aeruginosa is an opportunistic bacterial pathogen that often encounters hypoxic/anoxic environments within the host, which increases its tolerance to many conventional antibiotics. Toward identifying novel treatments, we explored the therapeutic potential of chlorate, a pro-drug that kills hypoxic/anoxic, antibiotic-tolerant P. aeruginosa populations.

MTCH2 is a mitochondrial outer membrane protein insertase.

In the mitochondrial outer membrane, α-helical transmembrane proteins play critical roles in cytoplasmic-mitochondrial communication. Using genome-wide CRISPR screens, we identified mitochondrial carrier homolog 2 (MTCH2), and its paralog MTCH1, and showed that it is required for insertion of biophysically diverse tail-anchored (TA), signal-anchored, and multipass proteins, but not outer membrane β-barrel proteins. Purified MTCH2 was sufficient to mediate insertion into reconstituted proteoliposomes.

Surface cysteines could protect the SARS-CoV-2 main protease from oxidative damage.

The SARS-CoV-2 main protease (M) is responsible for cleaving twelve nonstructural proteins from the viral polyprotein. M, a cysteine protease, is characterized by a large number of noncatalytic cysteine (Cys) residues, none involved in disulfide bonds. In the absence of a tertiary-structure stabilizing role for these residues, a possible alternative is that they are involved in redox processes.

The Social Bridging Project: Intergenerational Phone-Based Connections With Older Adults During the COVID-19 Pandemic.

Millions of Americans aged 65 are socially isolated and millions more report feeling lonely. Social isolation and loneliness in older adults were compounded by stay-at-home orders and other COVID-19 prevention measures. Although many Americans experienced no difficulties transitioning to the use of electronic devices as their primary means of communication and connection, some older adults were not similarly able to espouse this shift.

Circadian neurons in the paraventricular nucleus entrain and sustain daily rhythms in glucocorticoids.

Signals from the central circadian pacemaker, the suprachiasmatic nucleus (SCN), must be decoded to generate daily rhythms in hormone release. Here, we hypothesized that the SCN entrains rhythms in the paraventricular nucleus (PVN) to time the daily release of corticosterone. In vivo recording revealed a critical circuit from SCN vasoactive intestinal peptide (SCN)-producing neurons to PVN corticotropin-releasing hormone (PVN)-producing neurons.

Point absorbers in Advanced LIGO.

Small, highly absorbing points are randomly present on the surfaces of the main interferometer optics in Advanced LIGO. The resulting nanometer scale thermo-elastic deformations and substrate lenses from these micron-scale absorbers significantly reduce the sensitivity of the interferometer directly though a reduction in the power-recycling gain and indirect interactions with the feedback control system. We review the expected surface deformation from point absorbers and provide a pedagogical description of the impact on power buildup in second generation gravitational wave detectors (dual-recycled Fabry-Perot Michelson interferometers).
