Article Synopsis
  • CRISPR diagnostics face challenges like low signal efficiency and sensitivity due to their reliance on single-stranded nucleic acid fluorescent reporters.
  • The new CrisprAIE system combines CRISPR/Cas reactions with innovative aggregation-induced emission luminogens (AIEgens) for more effective fluorescence and improved clinical detection of norovirus and SARS-CoV-2.
  • CrisprAIE shows a substantial increase in sensitivity—up to 270 times better—compared to traditional CRISPR diagnostics and has potential for broader application in improving detection methods across various CRISPR-based techniques.

Pseudouridine (Ψ) is one of the most abundant modifications in cellular RNA. However, its function remains elusive, mainly due to the lack of highly sensitive and accurate detection methods. Here, we introduced 2-bromoacrylamide-assisted cyclization sequencing (BACS), which enables Ψ-to-C transitions, for quantitative profiling of Ψ at single-base resolution.

Background: β-adrenergic receptor (β-AR) overactivation is a major pathological cue associated with cardiac injury and diseases. AMPK (AMP-activated protein kinase), a conserved energy sensor, regulates energy metabolism and is cardioprotective. However, whether AMPK exerts cardioprotective effects via regulating the signaling pathway downstream of β-AR remains unclear.

Article Synopsis
  • Therapeutic HPV vaccines are needed to induce strong cellular immunity and treat existing infections but face challenges, particularly with current delivery methods like electroporation (EP), which can cause pain and muscle damage.
  • DNA-based HPV vaccines appear promising with good safety and efficacy, but EP's complexity and cost limit their clinical use.
  • In preclinical tests, lipid nanoparticles (LNPs) significantly improved the immune response from DNA vaccines compared to EP, with SM-102 LNP M showing the best results, suggesting LNPs could offer a better delivery method.

Background: Patients with relapsed or refractory hematologic cancers have a poor prognosis. Chimeric antigen receptor (CAR) T-cell therapy as a bridge to allogeneic hematopoietic stem-cell transplantation (HSCT) has the potential for long-term tumor elimination. However, pre-HSCT myeloablation and graft-versus-host disease (GVHD) prophylaxis agents have toxic effects and could eradicate residual CAR T cells and compromise antitumor effects.

The current small-scale synthesis and relatively large size of CuO have limited its practical applications. Herein, we developed a hydrolysis strategy to prepare phase-pure CuO networks composed of small granules (ca. 25 nm) on a gram scale.

Low-dimensional materials exhibit unique quantum confinement effects and morphologies as a result of their nanoscale size in one or more dimensions, making them exhibit distinctive physical properties compared to bulk counterparts. Among all low-dimensional materials, due to their atomic level thickness, two-dimensional materials possess extremely large shape anisotropy and consequently are speculated to have large optically anisotropic absorption. In this work, we demonstrate an optoelectronic device based on the combination of two-dimensional material and carbon dot with wide bandgap.

Article Synopsis
  • The study focuses on using adenosine deaminases acting on RNA (ADAR) for precise editing of RNA, addressing concerns about its effectiveness for therapy due to variable ADAR expression in tissues and species.
  • Researchers found that delivering circular ADAR-recruiting RNAs (arRNAs) using AAV (adeno-associated virus) led to around 80% editing efficiency in non-human primates without any noticeable toxicity over a 4 to 13-week period.
  • The successful correction of a genetic defect in a mouse model of Hurler syndrome suggests that AAV-delivered circular arRNAs could be a promising approach for therapeutic applications in humans.

Biologic drug discovery pipelines are designed to deliver protein therapeutics that have exquisite functional potency and selectivity while also manifesting biophysical characteristics suitable for manufacturing, storage, and convenient administration to patients. The ability to use computational methods to predict biophysical properties from protein sequence, potentially in combination with high throughput assays, could decrease timelines and increase the success rates for therapeutic developability engineering by eliminating lengthy and expensive cycles of recombinant protein production and testing. To support development of high-quality predictive models for antibody developability, we designed a sequence-diverse panel of 83 effector functionless IgG1 antibodies displaying a range of biophysical properties, produced and formulated each protein under standard platform conditions, and collected a comprehensive package of analytical data, including in vitro assays and in vivo mouse pharmacokinetics.

Background: Multiple screw-in attempts under fluoroscopy are often needed to place the pacing lead tip near or at the left bundle branch (LBB). This study was conducted to evaluate the feasibility of implanting an LBB pacing lead in the proximal LBB (PLBB) guided by intracardiac echocardiography (ICE).

Methods: The distribution of the LBB was initially determined by ICE anatomic imaging and 3-dimensional electrical mapping of His and LBB potentials in 20 patients in the first parts of the study.

Background A noninvasive coronary CT angiography (CCTA)-based radiomics technique may facilitate the identification of vulnerable plaques and patients at risk for future adverse events. Purpose To assess whether a CCTA-based radiomic signature (RS) of vulnerable plaques defined with intravascular US was associated with increased risk for future major adverse cardiac events (MACE). Materials and Methods In a retrospective study, an RS of vulnerable plaques was developed and validated using intravascular US as the reference standard.

Switchable second harmonic generation (SHG) materials have potential applications in information storage, signal processing, and so on because they can switch between SHG-on and SHG-off states.

In Canada, many mines have adopted the sublevel stoping method, such a blasthole stoping (BHS), to extract steeply deposited minerals. Sill pillars are usually kept in place in this mining method to support the weight of the overburden in underground mining. To prolong the mine's life, sill pillars will be recovered, and sill pillar recovery could cause failures, fatality, and equipment loss in the stopes.

  • Platinum-based chemotherapy, specifically toripalimab combined with paclitaxel and cisplatin, was tested against a placebo in a phase 3 trial for patients with advanced esophageal squamous cell carcinoma (ESCC).
  • The results showed that those treated with toripalimab experienced significantly better progression-free survival (PFS) and overall survival (OS) compared to the placebo group.
  • Both treatment groups had similar rates of serious side effects, indicating that the toripalimab plus chemotherapy regimen is effective and has a manageable safety profile.
