HBI Transcription Factor-Mediated ROS Homeostasis Regulates Nitrate Signal Transduction.

Plant Cell 2021 Jun 15. Epub 2021 Jun 15.

The Key Laboratory of Plant Development and Environmental Adaptation Biology, Ministry of Education, School of Life Sciences, Shandong University, Qingdao, 266237, China.

Nitrate is both an important nutrient and a critical signaling molecule that regulates plant metabolism, growth, and development. Although several components of the nitrate signaling pathway have been identified, the molecular mechanism of nitrate signaling remains unclear. Here, we showed that the growth-related transcription factors HOMOLOG OF BRASSINOSTEROID ENHANCED EXPRESSION2 INTERACTING WITH IBH1 (HBI1) and its three closest homologs (HBIs) positively regulate nitrate signaling in Arabidopsis thaliana.

Robot-assisted arm therapy in neurological health conditions: rationale and methodology for the evidence synthesis in the CICERONE Italian Consensus Conference.

Eur J Phys Rehabil Med 2021 Jun 15. Epub 2021 Jun 15.

Department of Electrical and Information Engineering, Politecnico di Bari, Bari, Italy.

Background: Robot-assisted Arm Therapy (RAT) has been increasingly applied in the last years for promoting functional recovery in patients with disabilities related to neurological health conditions. Evidence of a knowledge-to-action gap for applying robot-assisted technologies in the rehabilitation of patients with neurological health conditions and the difficulty to apply and tailor the knowledge to the local contexts solicited the need for a national consensus conference on these interventions.

A human isogenic iPSC-derived cell line panel identifies major regulators of aberrant astrocyte proliferation in Down syndrome.

Commun Biol 2021 Jun 14;4(1):730. Epub 2021 Jun 14.

Department of Pediatrics, Graduate School of Medicine, Osaka University, Suita, Osaka, Japan.

Astrocytes exert adverse effects on the brains of individuals with Down syndrome (DS). Although a neurogenic-to-gliogenic shift in the fate-specification step has been reported, the mechanisms and key regulators underlying the accelerated proliferation of astrocyte precursor cells (APCs) in DS remain elusive. Here, we established a human isogenic cell line panel based on DS-specific induced pluripotent stem cells, the XIST-mediated transcriptional silencing system in trisomic chromosome 21, and genome/chromosome-editing technologies to eliminate phenotypic fluctuations caused by genetic variation.

Exploring temporal interactions of crash counts in California using distinct log-linear contingency table models.

Int J Inj Contr Saf Promot 2021 Jun 14:1-16. Epub 2021 Jun 14.

Division of Research, Innovation and System Information, California Department of Transportation, Sacramento, CA, USA.

Temporal trait of crashes has huge impact on road crash occurrence and a large proportion of research have considered different time periods to determine the causes and features of crash occurrence or frequency. Compared with other safety studies based on a single time interval, considerably less research has relied on the use of multiple time units, especially for the time intervals of less than one year. The research aims to fill the gap by investigating the temporal distribution of crash counts using multiple time spans including hour, weekday and month. Read More

Exploiting single-electron transfer in Lewis pairs for catalytic bond-forming reactions.

Chem Sci 2020 Mar 20;11(17):4305-4311. Epub 2020 Mar 20.

Institute of Transformative Bio-Molecules (WPI-ITbM), Department of Molecular and Macromolecular Chemistry, Graduate School of Engineering, Nagoya University Nagoya 464-8601 Japan

A single-electron transfer (SET) between tris(pentafluorophenyl)borane (B(CF)) and ,-dialkylanilines is reported, which is operative the formation of an electron donor-acceptor (EDA) complex involving π-orbital interactions as a key intermediate under dark conditions or visible-light irradiation depending on the structure of the aniline derivatives. This inherent SET in the Lewis pairs initiates the generation of the corresponding α-aminoalkyl radicals and their additions to electron-deficient olefins, revealing the ability of B(CF) to act as an effective one-electron redox catalyst.

Human tRNAs with inosine 34 are essential to efficiently translate eukarya-specific low-complexity proteins.

Nucleic Acids Res 2021 Jun 14. Epub 2021 Jun 14.

Institute for Research in Biomedicine, The Barcelona Institute of Science and Technology, Barcelona, Catalonia 08028, Spain.

The modification of adenosine to inosine at the wobble position (I34) of tRNA anticodons is an abundant and essential feature of eukaryotic tRNAs. The expansion of inosine-containing tRNAs in eukaryotes followed the transformation of the homodimeric bacterial enzyme TadA, which generates I34 in tRNAArg and tRNALeu, into the heterodimeric eukaryotic enzyme ADAT, which modifies up to eight different tRNAs. The emergence of ADAT and its larger set of substrates, strongly influenced the tRNA composition and codon usage of eukaryotic genomes. Read More

Monitoring Diagnostic Safety Risks in Emergency Departments: Protocol for a Machine Learning Study.

JMIR Res Protoc 2021 Jun 14;10(6):e24642. Epub 2021 Jun 14.

Health Care Delivery Research, Kern Center for the Science of Health Care Delivery, Mayo Clinic, Rochester, MN, United States.

Background: Diagnostic decision making, especially in emergency departments, is a highly complex cognitive process that involves uncertainty and susceptibility to errors. A combination of factors, including patient factors (eg, history, behaviors, complexity, and comorbidity), provider-care team factors (eg, cognitive load and information gathering and synthesis), and system factors (eg, health information technology, crowding, shift-based work, and interruptions) may contribute to diagnostic errors. Using electronic triggers to identify records of patients with certain patterns of care, such as escalation of care, has been useful to screen for diagnostic errors. Read More

Channing Division of Network Medicine, Brigham and Women's Hospital and Harvard Medical School, Boston, MA, 02115, USA.

Finding an optimal set of nodes, called key players, whose activation (or removal) would maximally enhance (or degrade) certain network functionality, is a fundamental class of problems in network science. Potential applications include network immunization, epidemic control, drug design, and viral marketing. Due to their general NP-hard nature, those problems typically cannot be solved by exact algorithms with polynomial time complexity. Read More
