Article Synopsis
  • A universal stress protein (USP) family exists in a variety of species, including wheat, and is important for responding to different stress conditions such as heat and toxins.
  • Researchers discovered 88 USP genes in wheat and classified them into four distinct subfamilies, showing evolutionary conservation between monocots and dicots.
  • Experiments revealed that the TaUSP85 gene plays a crucial role in enhancing stress tolerance and silencing this gene led to adverse effects like wilting and increased damage in wheat plants, indicating the significance of USPs in plant stress responses.

Achieving a narrow emission bandwidth is long pursued for display applications. Among all primary colors, obtaining pure red emission with high visual perception is the most challenging. In this work, CsPbI halide perovskite nanoplatelets (NPLs) with rigorously controlled 2D  [PbI] octahedron layer number (n) are demonstrated.

Background: Flavonoids are one of the bioactive ingredients of Lonicera macranthoides (L. macranthoides), however, their biosynthesis in the flower is still unclear. In this study, combined transcriptomic and targeted metabolomic analyses were performed to clarify the flavonoids biosynthesis during flowering of L.

Dihydroquinazolinone (DHQZ) has recently been harnessed as a ketone-derived pro-aromatic reagent extensively employed in (metalla)photoredox reactions as versatile group transfer agents. In this work, we outline a column chromatography-free protocol for the multigram-scale synthesis of pro-aromatic DHQZs as well as its use in a gram-scale nickel/photoredox dual-catalyzed cross-coupling in single-batch, photoflow, and simultaneous multiple smaller batches. While the single-batch approach leveraged moderate yields, a simple plug-flow photoreactor also exhibited amenable productivity (up to 45 % yield) despite the use of a heterogeneous base.

The regulation of gene expression in mammalian cells by combining various cis-regulatory features has rarely been discussed. In this study, we constructed expression vectors containing various combinations of regulatory elements to examine the regulation of gene expression by different combinations of cis-regulatory elements. The effects of four promoters (CMV promoter, PGK promoter, Polr2a promoter, and EF-1α core promoter), two enhancers (CMV enhancer and SV40 enhancer), two introns (EF-1α intron A and hybrid intron), two terminators (CYC1 terminator and TEF terminator), and their different combinations on downstream gene expression were compared in various mammalian cells using fluorescence microscopy to observe fluorescence, quantitative real-time PCR (qRT-PCR), and western blot.

Purpose: Benign prostatic hyperplasia (BPH) describes common noncancerous prostate enlargement. BPH is usually associated with lower urinary tract symptoms and an increased risk of cerebrovascular diseases, such as stroke and its recurrence. White matter hyperintensities (WMHs), markers of cerebral injury, increase the risk of stroke, cognitive impairment, dementia, and death.

Pseudorabies virus (PRV) is a contagious herpesvirus that causes Aujeszky's disease and economic losses worldwide. Liver X receptors (LXRs) belong to the nuclear receptor superfamily and are critical for the control of lipid homeostasis. However, the role of LXR in PRV infection has not been fully established.

The C-S activation and sulfur removal from native thiols is challenging, which limits their application as feedstock materials in organic synthesis despite their natural abundance. Herein, we introduce a per-/polyfluoroaryl moiety, which serves as a redox-active scaffold, into sp-hybridized thiols to activate the C-S bond. Using a Ni catalyst with MgBr as an additive, the S group can be removed to yield an aliphatic radical that can react with an aryl halide in a reductive cross-coupling.

Herein we report ketones as feedstock materials in radical cross-coupling reactions under Ni/photoredox dual catalysis. In this approach, simple condensation first converts ketones into prearomatic intermediates that then act as activated radical sources for cross-coupling with aryl halides. Our strategy enables the direct benzylation/benzoylation of (hetero)arenes under mild reaction conditions with high functional group tolerance.

Sidewall emission of a micro-scale light emitting diode (micro-LED) improves the light extraction efficiency, but it causes mismatched angular distributions between AlGaInP-based red micro-LED and InGaN-based blue/green counterparts due to material difference. As a result, color shift of RGB micro-LED displays may become visually noticeable. To address this issue, we first analyze the angular distributions of RGB micro-LEDs and obtain good agreement between simulation and experiment.

Transcription factors regulate alteration of transcription levels. Recently, huge amount of transcriptomic data are accumulated via the application of high throughput sequencing technology, and it is reasonable to postulate that in-depth analysis of transcription data could be used to enhance gene annotation. In this study, we chose the gene family of rice WRKY transcription factors.

Objective: To investigate the clinical significance of changes in T wave and ST segment amplitudes on electrocardiogram (ECG) from supine to standing position in children with unexplained chest tightness or pain in resting stage.

Methods: A total of 122 6-14-year-old children with a chief complaint of unexplained chest tightness or pain (resting stage) underwent head-up tilt test (HUTT). According to HUTT results, these children were divided into HUTT-positive (n=61) and HUTT-negative groups (n=61).

Objective: To investigate the clinical significance of 24-hour blood pressure monitoring (ABPM) for evaluating the treatment outcome of nerve-mediated syncope (NMS) in children.

Methods: Twenty-eight children with NMS confirmed by a head-up tilt table test (HUTT) (12 males and 16 females, aged 6-13 years) and with a chief complaint of unexplained syncope or pre-syncope between February 2010 and August 2012, were included in the study. These children received health education combined with therapy using oral rehydration salts solution and were then reexamined for clinical symptoms as well as HUTT and ABPM results.
