Chilling- and dark-regulated photoprotection in Miscanthus, an economically important C grass.

Tolerance of chilling dictates the geographical distribution, establishment, and productivity of C crops. Chilling reduces enzyme rate, limiting the sink for the absorbed light energy leading to the need for quick energy dissipation via non-photochemical quenching (NPQ). Here, we characterize NPQ upon chilling in three Miscanthus accessions representing diverse chilling tolerance in C grasses.

Prolonged Immunomodulator Delivery Boosts Monocyte Exosome Secretion and Elevates Cathelicidin/LL-37 Content.

Human cathelicidin LL-37 offers significant benefits to the immune system and in treating various diseases, but its therapeutic potential is hindered by low activity and instability in physiological environments. Here, we introduce a strategy to boost LL-37 levels in exosomes derived from THP-1 monocytes by incubating cells with electrospun nanofibers containing immunomodulators (e.g.

Gut microbiota profiling in injection drug users with and without HIV-1 infection in Puerto Rico.

Introduction: The full extent of interactions between human immunodeficiency virus (HIV) infection, injection drug use, and the human microbiome is unclear. In this study, we examined the microbiomes of HIV-positive and HIV-negative individuals, both drug-injecting and non-injecting, to identify bacterial community changes in response to HIV and drug use. We utilized a well-established cohort of people who inject drugs in Puerto Rico, a region with historically high levels of injection drug use and an HIV incidence rate disproportionately associated with drug use.

Independent and Interactive Impacts of Prenatal Exposure to Legal Substances and Childhood Trauma on Emotion Processing in Pre-Adolescents: Preliminary Findings From the ABCD Study.

Objective: This paper investigated the effects of prenatal drug exposure (PDE), childhood trauma (CT), and their interactions on the neurobiological markers for emotion processing.

Method: Here, in a non-clinical sample of pre-adolescents (9-10 years of age) from the Adolescent Brain Cognitive Development (ABCD) Study (N = 6,146), we investigate the impact of PDE to commonly used substances (ie, alcohol, cigarettes, and marijuana), CT, and their interaction on emotion processing. From the Emotional N-back functional magnetic resonance imaging task data, we selected 26 regions of interests, previously implicated in emotion processing, and conducted separate linear mixed models (108 total) and accounted for available environmental risk factors.

DeepMiRBP: a hybrid model for predicting microRNA-protein interactions based on transfer learning and cosine similarity.

Background: Interactions between microRNAs and RNA-binding proteins are crucial for microRNA-mediated gene regulation and sorting. Despite their significance, the molecular mechanisms governing these interactions remain underexplored, apart from sequence motifs identified on microRNAs. To date, only a limited number of microRNA-binding proteins have been confirmed, typically through labor-intensive experimental procedures.

This study examines the impact of the complex microbiota from long-term fermented kimchi, used as a backslop, on fermentation dynamics. The fermentation was conducted with autoclaved (group A) and non-autoclaved (NA) starter cultures. Bacterial and fungal communities were analyzed with 16S rRNA gene V4 and ITS2 region, respectively, and metabolites were profiled using gas chromatography-mass spectrometry.

Photosynthetic demands on translational machinery drive retention of redundant tRNA metabolism in plant organelles.

Eukaryotic nuclear genomes often encode distinct sets of translation machinery for function in the cytosol vs. organelles (mitochondria and plastids). This raises questions about why multiple translation systems are maintained even though they are capable of comparable functions and whether they evolve differently depending on the compartment where they operate.

Mechanochemical topological defects in an active nematic.

We propose a reaction-diffusion system that converts topological information of an active nematic into chemical signals. We show that a curvature-activated reaction dipole is sufficient for creating a system that dynamically senses topology by producing a concentration field possessing local extrema coinciding with ±1/2 defects. The enabling term is analogous to polarization charge density seen in dielectric materials.

Brain endothelial permeability, transport, and flow assessed over 10 orders of magnitude using the in situ brain perfusion technique.

Background: Cerebral blood flow normally places a limit on the magnitude of brain vascular permeability (P) that can be measured in vivo. At normal cerebral blood flow, this limit falls at the lower end of lipophilicity for most FDA-approved CNS drugs. In this study, we report on two methods that can be used to overcome this limitation and measure brain vascular permeability values that are up to ~1000 times higher using the in situ brain perfusion technique.

Shifting evaluative construal: Common and distinct neural components of moral, pragmatic, and hedonic evaluations.

People generate evaluations of different attitude objects based on their goals and aspects of the social context. Prior research suggests that people can shift between at least three types of evaluations to judge whether something is good or bad: (how costly or beneficial it is), (whether it is aligned with moral norms), and (whether it feels good; Van Bavel et al., 2012).

Room temperature polaritonic soft-spin XY Hamiltonian in organic-inorganic halide perovskites.

Exciton-polariton condensates, due to their nonlinear and coherent characteristics, have been employed to construct spin Hamiltonian lattices for potentially studying spin glass, critical dephasing, and even solving optimization problems. Here, we report the room-temperature polariton condensation and polaritonic soft-spin XY Hamiltonian lattices in an organic-inorganic halide perovskite microcavity. This is achieved through the direct integration of high-quality single-crystal samples within the cavity.

Analysis of solution-phase biomolecular interactions by liquid chromatography: General strategies and recent developments.

The analysis of biomolecular interactions is important in characterizing and understanding many fundamental processes that occur in the body and biological systems. A variety of methods are available for studying the extent and rate of binding of these interactions. Some of these techniques are homogeneous methods, with all interacting components being present in the solution-phase, while others are heterogeneous, such as involving both solution-phase and solid-phase components.

"I didn't go into medicine just to be on the phone": Emotional Expression as Sacrosanct During Derious Illness Patient-Physician Advanced Cancer Care Communication During the COVID-19 Pandemic.

Guided by communication accommodation theory, we studied 27 physician reports of patient-physician advanced cancer communication during the COVID-19 pandemic. Advanced cancer communication requires recognizing patients' psychosocial states and collaboratively engaging patients empathetically to develop the shared understanding necessary to guide decision-making. However, physicians found their communication underaccommodated, stemming from personal protection equipment, social distancing, and telemedicine.

Intrinsic and environmental drivers of pairwise cohesion in wild Canis social groups.

Animals within social groups respond to costs and benefits of sociality by adjusting the proportion of time they spend in close proximity to other individuals in the group (cohesion). Variation in cohesion between individuals, in turn, shapes important group-level processes such as subgroup formation and fission-fusion dynamics. Although critical to animal sociality, a comprehensive understanding of the factors influencing cohesion remains a gap in our knowledge of cooperative behavior in animals.
