"We don't do any of these things because we are a death-denying culture": Sociocultural perspectives of Black and Latinx cancer caregivers.

Objectives: Cancer is an enormous public health burden among Black and Latinx cancer survivors, and they are at risk of facing barriers to accessing cancer treatment and support in the United States. This study explored the unique challenges and experiences faced by Black and Latinx cancer survivors through the lens of their caregivers, including the specific cultural, social, and systemic factors that influence cancer survivorship experience and quality of life within these communities in the United States.

Methods: We used a qualitative descriptive design for the study, and conducted 6 focus group discussions (3 Latinx and 3 Black groups) with a total of 33 caregivers of cancer survivors, (Mean age = 63 years).

Gaze behavior reveals automaticity and attention allocation during music teaching vs. observing.

In a unique case-study approach in which I served as both the research participant and the experimenter, I wore eye-tracking glasses while teaching a brief music lesson to two university students learning trumpet, then approximately two weeks later, I watched a video of the lesson and tracked my gaze again. To investigate unconscious perceptual processes engaged during music teaching, I compared my attention allocation while teaching to my attention allocation during selfobservation. My gaze behavior while teaching revealed a high level of automaticity regarding lesson sequencing and allocation of attention.

Polyploidy and the evolution of phenotypic integration: Network analysis reveals relationships among anatomy, morphology, and physiology.

Premise: Most traits are polygenic and most genes are pleiotropic, resulting in complex, integrated phenotypes. Polyploidy presents an excellent opportunity to explore the evolution of phenotypic integration as entire genomes are duplicated, allowing for new associations among traits and potentially leading to enhanced or reduced phenotypic integration. Despite the multivariate nature of phenotypic evolution, studies often rely on simplistic bivariate correlations that cannot accurately represent complex phenotypes or data reduction techniques that can obscure specific trait relationships.

Drivers of resource allocation for breeding under variable environments in a bet hedger.

The evolutionary theory of life histories predicts that there is a trade-off between survival and reproduction: since adult survival in long-lived organisms is high, then breeding investment is more variable and more dependent on conditions (e.g. food availability and individual experience).

Assessment of the Value of a Carriage System to Organize and Elevate Intravenous Tubing.

Caregiver/patient fall injury risks increase when medical tubing drapes on floors. The objective of this research was to examine the value of a novel carriage system that organizes and elevates medical and intravenous (IV) tubing. Using a prospective, multicenter, cohort design, value of the IV carriage system was assessed using a valid, reliable survey that provided the total score and scores of 3 involvement factors: personal relevance, attitude, and importance.

"He [the doctor] said I should go and wait for my death:" Dualities in care and support access among female cancer survivors.

Introduction: While some countries have positive outlooks and technology at their disposals to detect and treat cancer in its earliest stages, other countries frequently demonstrate trends of late-stage presentation and treatment hesitancy. Nigeria is a nation that has a high cancer burden, with poorer outcomes than higher income countries (HICs). To add to the body of cancer knowledge in global health, and inform relevant policies to improve cancer survivorship, our study offers insight on cancer survivors' experiences in accessing care and support in Nigeria.

Population genomic analyses support sympatric origins of parapatric morphs in a salamander.

In numerous clades, divergent sister species have largely non-overlapping geographic ranges. This pattern presumably arises because species diverged in allopatry or parapatry, prior to a subsequent contact. Here, we provide population-genomic evidence for the opposite scenario: previously sympatric ecotypes that have spatially separated into divergent monomorphic populations over large geographic scales (reverse sympatric scenario).

Can predators stabilize host-parasite interactions? Changes in aquatic predator identity alter amphibian responses and parasite abundance across life stages.

The role of parasites can change depending on the food web community. Predators, for instance, can amplify or dilute parasite effects on their hosts. Likewise, exposure to parasites or predators at one life stage can have long-term consequences on individual performance and survival, which can influence population and disease dynamics.

Low-generation fluorescent polyurethane dendrimers late-stage modification using azide-alkyne click chemistry.

Protecting group free one-pot multicomponent Curtius reaction afforded a versatile MN type dendron, ensuring late-stage modification of both dendron and dendrimer to afford highly fluorescent symmetrical and unsymmetrical (Janus) polyurethane dendrimers. Fluorescence study of these dendrimers exhibited the Förster resonance energy transfer (FRET) between blue and mint green fluorophores.

Caste and COVID-19: Psychosocial disparities amongst rural Indian women during the coronavirus pandemic.

The COVID-19 pandemic has exacerbated preexisting mental health disparities. In India, marginalization based on caste membership, gender, and rural residence are critical determinants of inequity across the lifespan. Guided by the theoretical frameworks of minority stress and intersectionality, this study examined caste-based disparities in fear of coronavirus (FOC), mental health symptoms, and perceived loneliness amongst rural women in north India during the COVID-19 pandemic.

Evaluating the role of body size and habitat type in movement behavior in human-dominated systems: A frog's eye view.

Animal movement is a key process that connects and maintains populations on the landscape, yet for most species, we do not understand how intrinsic and extrinsic factors interact to influence individual movement behavior.Land-use/land-cover changes highlight that connectivity among populations will depend upon an individual's ability to traverse habitats, which may vary as a result of habitat permeability, individual condition, or a combination of these factors.We examined the effects of intrinsic (body size) and extrinsic (habitat type) factors on desiccation tolerance, movement, and orientation in three anuran species (American toads, ; northern leopard frogs, ; and Blanchard's cricket frogs, ) using laboratory and field studies to connect the effects of susceptibility to desiccation, size, and movement behavior in single-habitat types and at habitat edges.

Distinguishing chemically induced NADPH- and NADH-related metabolic responses using phasor analysis of UV-excited autofluorescence.

NADPH and NADH are well known for their role in antioxidant defense and energy metabolism, respectively, however distinguishing their cellular autofluorescence signals is a challenge due to their nearly identical optical properties. Recent studies applying spectral phasor analysis to autofluorescence emission during chemically induced metabolic responses showed that two-component spectral behavior, , spectral change acting as a superposition of two spectra, depended on whether one or multiple metabolic pathways were affected. Here, we use this property of spectral behavior to show that metabolic responses primarily involving NADPH or NADH can be distinguished.

Using Community Science to Better Understand Lead Exposure Risks.

Lead (Pb) is a neurotoxicant that particularly harms young children. Urban environments are often plagued with elevated Pb in soils and dusts, posing a health exposure risk from inhalation and ingestion of these contaminated media. Thus, a better understanding of where to prioritize risk screening and intervention is paramount from a public health perspective.

Factors associated with COVID-19 pandemic induced post-traumatic stress symptoms among adults living with and without HIV in Nigeria: a cross-sectional study.

Background: Nigeria is a country with high risk for traumatic incidences, now aggravated by the COVID-19 pandemic. This study aimed to identify differences in COVID-19 related post-traumatic stress symptoms (PTSS) among people living and not living with HIV; to assess whether PTSS were associated with COVID-19 pandemic-related anger, loneliness, social isolation, and social support; and to determine the association between PTSS and use of COVID-19 prevention strategies.

Methods: The data of the 3761 respondents for this analysis was extracted from a cross-sectional online survey that collected information about mental health and wellness from a convenience sample of adults, 18 years and above, in Nigeria from July to December 2020.

Individual differences in risk perception and misperception of COVID-19 in the context of political ideology.

The COVID-19 pandemic has been characterized by misinformation, politicization of public health, and extreme differences in risk assessment. In two studies, we sought to understand factors that contribute to differences in people's understanding of the virus and associated risks. We found that conservative participants reported higher levels of acceptable risk, have lower risk estimates of activities, and endorsed more misinformation.

An Adenovirus early region 4 deletion mutant induces G2/M arrest via ATM activation and reduces expression of the mitotic marker phosphorylated (ser10) histone 3.

Adenovirus (Ad) type 5 (Ad5) early region 4 (E4) proteins inhibit the DNA damage response (DDR) including activation of the DDR kinase ATM and its substrates, which can induce G2/M cell cycle arrest. Infection with Ad5 or the E4 deletion mutant H5dl1007 (1007) resulted in the accumulation of post G1 cells with > 2 N cellular DNA content. A greater fraction of cells with 4 N DNA content was observed in 1007 infections compared to Ad5; this population was dependent on activation of ATM.

Algae to angiosperms: Autofluorescence for rapid visualization of plant anatomy among diverse taxa.

Premise: Fluorescence microscopy is an effective tool for viewing plant internal anatomy. However, using fluorescent antibodies or labels hinders throughput. We present a minimal protocol that takes advantage of inherent autofluorescence and aldehyde-induced fluorescence in plant cellular and subcellular structures to markedly increase throughput in cellular and ultrastructural visualization.

Folding-controlled assembly of -phenylene-based macrocycles.

The self-assembly of foldamers into macrocycles is a simple approach to non-biological higher-order structure. Previous work on the co-assembly of -phenylene foldamers with rod-shaped linkers has shown that folding and self-assembly affect each other; that is, the combination leads to new emergent behavior, such as access to otherwise unfavorable folding states. To this point this relationship has been passive.

Elusive structural changes of New Delhi metallo-β-lactamase revealed by ultraviolet photodissociation mass spectrometry.

We use mass spectrometry (MS), under denaturing and non-denaturing solution conditions, along with ultraviolet photodissociation (UVPD) to characterize structural variations in New Delhi metallo-β-lactamase (NDM) upon perturbation by ligands or mutation. Mapping changes in the abundances and distributions of fragment ions enables sensitive detection of structural alterations throughout the protein. Binding of three covalent inhibitors was characterized: a pentafluorphenyl ester, an -aryloxycarbonyl hydroxamate, and ebselen.

Globally, plant-soil feedbacks are weak predictors of plant abundance.

Plant-soil feedbacks (PSFs) have been shown to strongly affect plant performance under controlled conditions, and PSFs are thought to have far reaching consequences for plant population dynamics and the structuring of plant communities. However, thus far the relationship between PSF and plant species abundance in the field is not consistent. Here, we synthesize PSF experiments from tropical forests to semiarid grasslands, and test for a positive relationship between plant abundance in the field and PSFs estimated from controlled bioassays.

Drinking Water Quality and Provision in Six Low-Income, Peri-Urban Communities of Lusaka, Zambia.

Lusaka, Zambia, is a rapidly growing city located on a vulnerable karstic dolomite aquifer that provides most of the city's drinking water. Over 65% of residents live in peri-urban communities with inadequate sanitation leading to widespread groundwater contamination and the spread of waterborne diseases such as cholera. To fill the water service gap, Water Trusts were created: public/private partnerships designed to provide clean water to peri-urban community residents.

Genetic modification of the flavonoid pathway alters growth and reveals flexible responses to enhanced UVB - Role of foliar condensed tannins.

Accumulation of certain phenolics is a well-known response of plants to enhanced UVB radiation (280-315 nm), but few experiments have compared the relative importance of different phenolic groups for UVB resilience. To study how an altered phenolic profile affects the responses and resilience of silver birch () to enhanced UVB, we used RNA interference (RNAi) targeting dihydroflavonol reductase (DFR), anthocyanidin synthase (ANS), or anthocyanidin reductase (ANR) to change the accumulation of phenolics. The unmodified control line and RNAi-modified plants were grown for 51 days under ambient or +32% enhanced UVB dose in a greenhouse.

Temperature, topography, soil characteristics, and NDVI drive habitat preferences of a shade-tolerant invasive grass.

Aim: Despite the large literature documenting the negative effects of invasive grasses, we lack an understanding of the drivers of their habitat suitability, especially for shade-tolerant species that do not respond positively to canopy disturbance. We aimed to understand the environmental niche and potential spatial distribution of a relatively new invasive species, wavyleaf basketgrass ( (Ard.) Roem.
