Decoding Codon Bias: The Role of tRNA Modifications in Tissue-Specific Translation.

The tRNA epitranscriptome has been recognized as an important player in mRNA translation regulation. Our knowledge of the role of the tRNA epitranscriptome in fine-tuning translation via codon decoding at tissue or cell levels remains incomplete. We analyzed tRNA expression and modifications as well as codon optimality across seven mouse tissues.

The Plethora of RNA-Protein Interactions Model a Basis for RNA Therapies.

The notion of RNA-based therapeutics has gained wide attractions in both academic and commercial institutions. RNA is a polymer of nucleic acids that has been proven to be impressively versatile, dating to its hypothesized RNA World origins, evidenced by its enzymatic roles in facilitating DNA replication, mRNA decay, and protein synthesis. This is underscored through the activities of riboswitches, spliceosomes, ribosomes, and telomerases.

Maternal exposure to legacy PFAS compounds PFOA and PFOS is associated with disrupted cytokine homeostasis in neonates: The Upstate KIDS study (2008-2010).

There is growing concern that exposure to per/polyfluoroalkyl substances (PFAS), persistent chemicals used widely to make consumer products water- or grease-proof, may alter immune function, leading to reduced vaccine response or greater susceptibility to infections. We investigated associations between two legacy PFAS (PFOA and PFOS) and infant cytokine levels measured in newborn dried bloodspots (NDBS) from a large population-based birth cohort in Upstate New York, to determine whether exposure to legacy PFAS is associated with variability in cytokine profiles in newborns. We performed adjusted mixed effects regressions for each cytokine against PFOS and PFOA followed by exploratory factor analysis (EFA) on specific cytokine subsets selected via the prior regressions.

Stipulations of cell and gene therapy and the ties to biomanufacturing.

Cell and gene therapy (CGT) products are emerging and innovative biopharmaceuticals that hold promise for treating diseases that are otherwise beyond the scope of conventional medicines. The evolution of CGT from a research idea to a promising therapeutic product is due to the complementary advancements across various scientific disciplines. First, the innovations and advancements in gene editing and delivery technology have provided fundamental tools to manipulate genes and cells for therapeutic pursuits.

Seasonal and periodic patterns in US COVID-19 mortality using the Variable Bandpass Periodic Block Bootstrap.

Since the emergence of the SARS-CoV-2 virus, research into the existence, extent, and pattern of seasonality has been of the highest importance for public health preparation. This study uses a novel bandpass bootstrap approach called the Variable Bandpass Periodic Block Bootstrap to investigate the periodically correlated components including seasonality within US COVID-19 mortality. Bootstrapping to produce confidence intervals for periodic characteristics such as the seasonal mean requires preservation of the periodically correlated component's correlation structure during resampling.

Stepwise reduction of an asymmetric π-expanded pyracylene towards the crystalline radical trianion.

The chemical reduction of a pyracylene-hexa--hexabenzocoronene-(HBC)-fused nanographene TPP was investigated with K and Rb metals to reveal its multi-electron acceptor abilities. The reaction of TPP with the above alkali metals, monitored by UV-vis-NIR and H NMR spectroscopy, evidenced the stepwise reduction process. The use of different solvents and secondary ligands enabled isolation of single crystals of three different reduced states of TPP with 1, 2, and 3 electrons added to its π-system.

Parsing the existential isolation-outcome association into its within- and between-patient components in naturalistic psychotherapy.

Complementing the oft-studied construct of isolation, research has increasingly focused on existential isolation (EI), or the subjective feeling of separateness in one's experience. In the clinical realm, several studies have demonstrated that higher EI is associated with more severe mental health problems at a single cross-section of time. Moreover, one study showed that higher pretreatment EI predicted worse psychotherapy outcomes.

Neighborhood opportunity and residential instability: associations with mental health in middle childhood.

Background: Neighborhood quality may contribute to child mental health, but families with young children often move, and residential instability has also been tied to adverse mental health. This study's primary goal was to disentangle the effects of neighborhood quality from those of residential instability on mental health in middle childhood.

Methods: 1,946 children from 1,652 families in the Upstate KIDS cohort from New York state, US, were followed prospectively from birth to age 10.

"Where There's a Will There's a Way": The Impact of State Variations in the Implementation of Continuous Coverage on Access to Postpartum Care During the Pandemic Emergency.

Objectives: To explore how the Medicaid continuous coverage requirement and unwinding process was implemented in three states with diverse existing policy environments and implications for the implementation of post-emergency 12-month postpartum extensions.

Data Sources: State data on unwinding performance and qualitative in-depth interviews with 48 stakeholders and patient-facing healthcare workers in Texas, New York and New Jersey.

Study Design: State Medicaid stakeholders and patient-facing healthcare workers in each state were interviewed with the goal of gaining insights into: (1) How the continuous coverage requirement was implemented; (2) What effects continuous coverage had on access to care for postpartum mothers; (3) How states are implementing the pandemic unwinding and postpartum extensions.

Population-Based vs. Health System and Insurer Records: Significant Underdiagnosis of Pcos - A Systematic Review.

Background: Polycystic ovary syndrome (PCOS) is one of the most prevalent cardio-metabolic disorders in women. However, PCOS diagnosis is often missed or delayed, which may have serious physical and mental health consequences. The extent of underdiagnosis remains unknown.

Hospital Boarding Creates Critical Shortcomings in Disaster Preparedness.

Hospital patient boarding in emergency departments has reached unprecedented crisis levels over the past 4 years. Boarding and crowding has been demonstrated by prior literature to have adverse effects on patient care as well as increased associated costs. Importantly, the increase in hospital patient boarding has created critical shortcomings in disaster preparedness by limiting the capacity of emergency departments to respond to mass casualty incidents due to space and staffing constraints.

Quick Freezing-Induced Au Nanoparticle Aggregates (QFIAAs) for Near-IR (NIR) Surface-Enhanced Raman Scattering (SERS) Substrates.

Here, we report a simple method to prepare near-IR (NIR) surface-enhanced Raman scattering (SERS) substrates by quickly freezing a citrate-capped Au nanoparticle (AuNP) solution in liquid nitrogen, followed by thawing it at room temperature. This process aggregates AuNPs in a controlled manner by forming ice crystals with smaller grain sizes when compared to a slow freezing process. The resulting smaller AuNP aggregates remain suspended in solution long enough to conduct high-throughput chemical analysis in a microwell plate using the NIR SERS spectroscopy.

Stabilizing Contorted Doubly-Reduced Tetraphenylene with Heavy Alkali Metal Complexation: Crystallographic and Theoretical Evidence.

The two-fold reduction of tetrabenzo[a,c,e,g]cyclooctatetraene (TBCOT, or tetraphenylene, 1) with K, Rb, and Cs metals reveals a distinctive core transformation pathway: a newly formed C-C bond converts the central eight-membered ring into a twisted core with two fused five-membered rings. This C-C bond of 1.589(3)-1.

Workplace factors associated with job satisfaction among dental hygienists and assistants in the United States.

Previous research has assessed job satisfaction and related workplace factors among healthcare workers. However, studies on dental care professionals are limited. This study aimed to evaluate job satisfaction among US dental hygienists (DHs) and assistants (DAs) and identify workplace factors contributing to their job satisfaction or dissatisfaction.

Health workforce issues and challenges in the post-pandemic era.

The health workforce is an essential component of our health care delivery system. A well-trained, sufficiently sized, and diverse workforce is critical to meet the health care needs of the population. However, in this postpandemic era, many challenges persist.

Continuing Education Certificate in Trauma Skills Among Emergency Nurses: A National Sample Survey Analysis.

Background: Trauma population health indicators are worsening in the United States. Nurses working in trauma care settings require specialized training for patient care. Little is known about national enumeration of nurses who hold skill-based trauma certificates.

Serendipitous Discovery of Dearomatized Dimers in Anthracene Derivative Oxidation.

We present the serendipitous discovery of an unusual dimer formed from anthracene-derived polyarenes. Unlike the typical oxidative coupling of substituted aromatic scaffolds, the reaction yielded a dearomatized enone dimer as the sole product. This dearomatized motif, notably, does not undergo the commonly observed rearomatization, and no biaryl products were detected.

A framework of multi-view machine learning for biological spectral unmixing of fluorophores with overlapping excitation and emission spectra.

The accuracy of assigning fluorophore identity and abundance, known as spectral unmixing, in biological fluorescence microscopy images remains a significant challenge due to the substantial overlap in emission spectra among fluorophores. In traditional laser scanning confocal spectral microscopy, fluorophore information is acquired by recording emission spectra with a single combination of discrete excitation wavelengths. However, organic fluorophores possess characteristic excitation spectra in addition to their unique emission spectral signatures.

A simple phylogenetic approach to analyze hypermutated HIV proviruses reveals insights into their dynamics and persistence during antiretroviral therapy.

Hypermutated proviruses, which arise in a single Human Immunodeficiency Virus (HIV) replication cycle when host antiviral APOBEC3 proteins introduce extensive guanine to adenine mutations throughout the viral genome, persist in all people living with HIV receiving antiretroviral therapy (ART). However, hypermutated sequences are routinely excluded from phylogenetic trees because their extensive mutations complicate phylogenetic inference, and as a result, we know relatively little about their within-host evolutionary origins and dynamics. Using >1400 longitudinal single-genome-amplified HIV sequences isolated from six women over a median of 18 years of follow-up-including plasma HIV RNA sequences collected over a median of 9 years between seroconversion and ART initiation, and >500 proviruses isolated over a median of 9 years on ART-we evaluated three approaches for masking hypermutation in nucleotide alignments.

Unveiling the Contribution of Hydrogen Radicals to Per- and Polyfluoroalkyl Substances (PFASs) Defluorination: Applicability and Degradation Mechanisms.

At present, the defluorination of per- and polyfluoroalkyl substances (PFASs), including perfluoroether compounds as substitutes of perfluorooctanoic acid (PFOA) and perfluorooctanesulfonate, is limited by the effective active species produced during the oxidation-reduction process. The contribution of the hydrogen radical (•H) as a companion active substance in the photoreduction and electrocatalytic degradation of PFASs has been neglected. Herein, we demonstrate that perfluorocarboxylic acids and perfluoroether compounds such as PFOA and hexafluoropropylene oxide dimer acid (GenX) underwent near-complete photodegradation and effective defluorination by continuously generating •H through perfluoroalkyl radical activation of water under UV irradiation without any reagents and catalysts.

Simulated retail food environments: A literature review of systems science approaches to advance equity in access to healthy diets.

As researchers increasingly utilize systems science simulation modeling (SSSM), little is known about how and by whom SSSMs are being leveraged to address inequities in access to healthy diets. We evaluated the extent to which studies (n = 66) employing SSSM to examine retail food environments (RFEs): included three pillars of equity (social position, human capital, socioeconomic and political context) that shape RFEs and access to healthy diets; grounded model design and development in theory; engaged with diverse stakeholders and lived experiences related to RFEs; and translated model findings towards addressing inequities in RFEs. Most studies (n = 58) included some model characteristics related to social position (e.

Stereo-seq of the prefrontal cortex in aging and Alzheimer's disease.

Aging increases the risk for Alzheimer's disease (AD), driving pathological changes like amyloid-β (Aβ) buildup, inflammation, and oxidative stress, especially in the prefrontal cortex (PFC). We present the first subcellular-resolution spatial transcriptome atlas of the human prefrontal cortex (PFC), generated with Stereo-seq from six male AD cases at varying neuropathological stages and six age-matched male controls. Our analyses revealed distinct transcriptional alterations across PFC layers, highlighted disruptions in laminar structure, and exposed AD-related shifts in layer-to-layer and cell-cell interactions.

Assessing Gaps in Integrated HIV and STI Testing Among New York State-Funded Providers by Pre-Exposure Prophylaxis Status: Implications for Status-Neutral Programming.

Background: In the United States, up to 75% of primary care patients go untested for HIV each year, and nearly two-thirds of adults report never having been tested for HIV. Integrated HIV and STI testing, combining these tests into a single visit, is recommended as a status neutral approach to prevention.

Setting: Over 200 New York State Department of Health-funded primary care clinics, hospitals, health centers and community-based organizations funded to conduct integrated screening.
