Distinguishing Chronic Inflammatory Demyelinating Polyneuropathy From Mimic Disorders: The Role of Statistical Modeling.

Background And Aims: Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is difficult to distinguish from mimicking disorders, with misdiagnosis resulting in IVIG overutilization. We evaluate a clinical-electrophysiological model to facilitate CIDP versus mimic neuropathy prediction.

Methods: Using the European Academy of Neurology/Peripheral Nerve Society (EAN/PNS) 2021 CIDP guidelines we derived 26 clinical and 144 nerve conduction variables.

Solid-State High Harmonic Generation in Common Large Bandgap Substrate Materials.

Solid-state high harmonic generation (sHHG) spectroscopy is an emerging ultrafast technique for studying key material properties such as electronic structure at and away from equilibrium. sHHG anisotropy measurements, where sHHG spectra are recorded depending on the driving electric field relative to the crystal lattice, have become a powerful tool for studying crystal symmetries. Previous works on two-dimensional materials and other quantum materials have often used substrate-supported samples, assuming that all sHHG signals originate from the sample due to the relatively large bandgap of the substrate.

Isocycloseram, a novel isoxazoline insecticide seed treatment for protection of wheat and barley and mortality of wireworms, Limonius californicus (Coleoptera: Elateridae).

Populations of various economic species of wireworms are increasing in the key cereal crop production areas of Canada and the United States. To address this problem, seed treatments are under development that both provide crop protection and significantly reduce populations equivalent in effectiveness to the formerly used but now deregistered organochlorine lindane. Herein, we evaluated isocycloseram (PLINAZOLIN technology), the first isoxazoline (GABA-gated Chloride Channel Allosteric Modulator) agricultural insecticide, as a seed treatment for the protection of cereal crops from the sugarbeet wireworm, Limonius californicus (Mannerheim).

Electron Transfer Dynamics at Dye-Sensitized SnO/TiO Core/Shell Electrodes in Aqueous/Nonaqueous Electrolyte Mixtures.

The dynamics of photoinduced electron transfer were measured at dye-sensitized photoanodes in aqueous (acetate buffer), nonaqueous (acetonitrile), and mixed solvent electrolytes by nanosecond transient absorption spectroscopy (TAS) and ultrafast optical-pump terahertz-probe spectroscopy (OPTP). Higher injection efficiencies were found in mixed solvent electrolytes for dye-sensitized SnO/TiO core/shell electrodes, whereas the injection efficiency of dye-sensitized TiO electrodes decreased with the increasing acetonitrile concentration. The trend in injection efficiency for the TiO electrodes was consistent with the solvent-dependent trend in the semiconductor flat band potential.

Reproductive Outcomes of Patients Undergoing Uterine Artery Embolization for Uterine Fibroids: Proceedings from The Dr. James B. Spies Summit for Uterine Fibroid Research-A Society of Interventional Radiology Foundation Research Consensus Panel.

Reproductive outcomes after uterine artery embolization (UAE) for the treatment of uterine fibroids are challenging to study, leaving several unanswered questions surrounding the future fertility of patients undergoing the procedure. Subject matter experts from interventional radiology, diagnostic radiology, obstetrics and gynecology, and reproductive medicine participated in a Society of Interventional Radiology (SIR) Foundation Research Consensus Panel to discuss and prioritize critical research topics focusing on fertility and reproductive outcomes in patients undergoing UAE for symptomatic uterine fibroids. After presentations and discussion of research ideas, the panelists prioritized the following topics for further investigation: (a) a prospective study of factors that influence implantation and gene expression in patients undergoing UAE or myomectomy over 1 year; (b) refinement of a classification system for uterine fibroids that can allow for more focused study design, which may include burden of fibroid disease; and (c) conjoint analysis/discrete choice experiments to better characterize those patients for whom fertility preservation is a high priority.

γ-Amino Alcohols via Energy Transfer Enabled Brook Rearrangement.

In the long-standing quest to synthesize fundamental building blocks with key functional group motifs, photochemistry in the recent past has comprehensively established its attractiveness. Amino alcohols are not only functionally diverse but are ubiquitous in the biologically active realm of compounds. We developed bench-stable bifunctional reagents that could then access the sparsely reported γ-amino alcohols directly from feedstock alkenes through energy transfer (EnT) photocatalysis.

Polymorphisms in two key anthocyanic genes of clivia (Clivia miniata L.) reveal evidence of selection and possible association with flower pigmentation.

Members of the genus Clivia show considerable variation in flower pigmentation and morphology. Such variation is affected by mutations that emerge in candidate flower development genes over time. Besides population history, mutations can further illuminate the effects of demographic events in populations in addition to population genetic parameters including selection, recombination, and linkage disequilibrium (LD).

A solid-state high harmonic generation spectrometer with cryogenic cooling.

Solid-state high harmonic generation (sHHG) spectroscopy is a promising technique for studying electronic structure, symmetry, and dynamics in condensed matter systems. Here, we report on the implementation of an advanced sHHG spectrometer based on a vacuum chamber and closed-cycle helium cryostat. Using an in situ temperature probe, it is demonstrated that the sample interaction region retains cryogenic temperature during the application of high-intensity femtosecond laser pulses that generate high harmonics.

Communicating with Your Department Chair: A Primer on How to Advocate for Your IR Section.

Many interventional radiologists express concern about communicating their practice needs to their radiology department chairs. As a result, they may have difficulty getting support for hiring of additional physicians and staff, capital investments in equipment, and marketing of IR services. Some perceive that chairs have a preference for diagnostic radiology initiatives over interventional and want to know why.

MIDA- and TIDA-Boronates Stabilize α-Radicals Through B-N Hyperconjugation.

Multifunctional organoboron compounds increasingly enable the simple generation of complex, Csp -rich small molecules. The ability of boron-containing functional groups to modify the reactivity of α-radicals has also enabled a myriad of chemical reactions. Boronic esters with vacant p-orbitals have a significant stabilizing effect on α-radicals due to delocalization of spin density into the empty orbital.

Modulation of Synaptic Plasticity Genes Associated to DNA Damage in a Model of Huntington's Disease.

Huntington's disease (HD) is a disease characterized by the progressive degeneration of nerve cells in the brain. DNA damage has been implicated in many neurological disorders; however, the association between this damage and the impaired signaling related to neurodegeneration is still unclear. The transcription factor c-AMP-responsive element binding protein (CREB) has a relevant role in the neuronal plasticity process regulating the expression of several genes, including brain-derived neurotrophic factor (BDNF).

Microbial biofilms as living photoconductors due to ultrafast electron transfer in cytochrome OmcS nanowires.

Light-induced microbial electron transfer has potential for efficient production of value-added chemicals, biofuels and biodegradable materials owing to diversified metabolic pathways. However, most microbes lack photoactive proteins and require synthetic photosensitizers that suffer from photocorrosion, photodegradation, cytotoxicity, and generation of photoexcited radicals that are harmful to cells, thus severely limiting the catalytic performance. Therefore, there is a pressing need for biocompatible photoconductive materials for efficient electronic interface between microbes and electrodes.
