Adenovirus-based therapies have encountered significant challenges due to host immunity, particularly from pre-existing antibodies. Many trials have struggled to evade antibody response; however, the efficiency of these efforts was limited by the diversity of antibody Fv-region recognizing multiple amino acid sequences. In this study, we developed an antibody-evading adenovirus vector by encoding a plasma-rich protein transferrin-binding domain.

Predicting whether a patient with cancer will benefit from immune checkpoint inhibitors (ICIs) without resorting to advanced genomic or immunologic assays is an important clinical need. To address this, we developed and evaluated SCORPIO, a machine learning system that utilizes routine blood tests (complete blood count and comprehensive metabolic profile) alongside clinical characteristics from 9,745 ICI-treated patients across 21 cancer types. SCORPIO was trained on data from 1,628 patients across 17 cancer types from Memorial Sloan Kettering Cancer Center.

Nanoporous metals have unique potentials for energy applications with a high surface area despite the percolating structure. Yet, a highly corrosive environment is required for the synthesis of porous metals with conventional dealloying methods, limiting the large-scale fabrication of porous structures for reactive metals. In this study, we synthesize a highly reactive Mg nanoporous system through a facile organic solution-based approach without any harsh etching.

Cellular growth and organismal development are remarkably complex processes that require the nutrient-responsive kinase mechanistic target of rapamycin complex 1 (mTORC1). Anticipating that important mTORC1 functions remained to be identified, we employed genetic and bioinformatic screening in C. elegans to uncover mechanisms of mTORC1 action.

We report a photosynthetic method for producing 2H-benzo[b][1,4]oxazin-2-ones from aryl azides and α-ketoacids. This method is highly sustainable, requiring only visible light irradiation of the substrates and no external additives. Furthermore, we implemented a continuous-flow system to achieve efficient light irradiation and rapid mixing, significantly improving reaction efficiency and reducing reaction time compared to the batch process.

Article Synopsis
  • Spatial transcriptomics (ST) technologies allow for in-depth gene expression analysis at a very fine scale, but traditional methods face challenges due to complex tissue structures and irregular cell shapes.
  • The new method, FICTURE, offers a segmentation-free approach that can analyze large-scale transcriptome data with submicron precision, making it compatible with different types of ST data.
  • FICTURE is significantly more efficient than existing methods and improves our understanding of intricate tissue architectures in challenging areas like vascular and fibrotic tissues, enhancing the exploration of high-resolution spatial transcriptomics.

Immunotherapy targeting immune checkpoints (ICPs), such as programmed death-ligand-1 (PD-L1), is used as a treatment option for advanced or metastatic non-small cell lung cancer (NSCLC). However, overall response rate to anti-PD-L1 treatment is limited due to antigen heterogeneity and the immune-suppressive tumor microenvironment. Human leukocyte antigen-G (HLA-G), an ICP as well as a neoexpressed tumor-associated antigen, is previously demonstrated to be a beneficial target in combination with anti-PD-L1.

  • Researchers conducted a trial comparing edoxaban monotherapy with dual antithrombotic therapy in patients with atrial fibrillation and stable coronary artery disease to assess risks of stroke and other serious outcomes.
  • The study involved 1,040 patients, with results showing fewer primary-outcome events in those on edoxaban alone (6.8% vs. 16.2% for dual therapy), indicating it may be safer.
  • Although the incidence of major bleeding was higher in the dual therapy group (14.2% vs. 4.7%), the major ischemic events were similar for both treatment groups.

A new asymmetric synthetic route to (+)- and (-)-limaspermidine was devised, starting with chirally resolved enantiomerically pure 2-pyrone Diels-Alder cycloadducts. This route utilizes intramolecular Pd-catalyzed aromatic C-H amidation and imino-Diels-Alder reactions to construct the key indoline and indolizidine subunits onto the central cyclohexane core, allowing the straightforward formal total syntheses of both (+)- and (-)-limaspermidine.

Photoreceptor degeneration is a major cause of untreatable blindness worldwide and has recently been targeted by emerging technologies, including cell- and gene-based therapies. Cell types of neural lineage have shown promise for replacing either photoreceptors or retinal pigment epithelial cells following delivery to the subretinal space, while cells of bone marrow lineage have been tested for retinal trophic effects following delivery to the vitreous cavity. Here we explore an alternate approach in which cells from the immature neural retinal are delivered to the vitreous cavity with the goal of providing trophic support for degenerating photoreceptors.

Obesity is a heritable disease, characterised by excess adiposity that is measured by body mass index (BMI). While over 1,000 genetic loci are associated with BMI, less is known about the genetic contribution to adiposity trajectories over adulthood. We derive adiposity-change phenotypes from 24.

  • - SARS-CoV-2 is continuously evolving, posing challenges to existing vaccines and treatments, which has led to the development of a new pipeline for creating effective VHH antibodies and bispecifics to neutralize various virus variants.
  • - High-affinity VHH antibodies were discovered through targeted phage library techniques, resulting in a bispecific construct that effectively combats multiple SARS-CoV-2 variants, showing enhanced resistance to antigenic escape.
  • - The new tetravalent bispecific platform enables speedy development and production of antibodies, providing flexible and potent responses to emerging variants, making it a promising method for ongoing viral management.

Article Synopsis
  • - The study investigates the effectiveness of amivantamab plus lazertinib compared to osimertinib in treating patients with advanced non-small-cell lung cancer (NSCLC) caused by specific genetic mutations.
  • - Results showed that patients receiving the amivantamab-lazertinib treatment had a significantly longer progression-free survival (23.7 months) than those on osimertinib (16.6 months), and the response rate was similar among both groups.
  • - Side effects primarily related to treatment were noted, but the overall survival analysis indicated a potential benefit for amivantamab-lazertinib over osimertinib, with fewer serious complications leading to treatment discontinuation.

This study investigates the hydrogen (H) production performance and bacterial communities in mesophilic (37 °C) and thermophilic (50 °C) H-producing consortia derived from different inoculum sources and utilizing food waste as a substrate. This study found notable variations in H production characteristics among these consortia. Among the mesophilic consortia (MC), the W-MC obtained with wetland (W) as the inoculum source exhibited the highest hydrogen production (3900 mL·L and 117 mL·L·h), while among the thermophilic consortia (TC), the FP-TC obtained with forest puddle sediment (FP) as the inoculum source showed the highest performance (2112 mL·L and 127 mL·L·h).
