PhoCl is a photocleavable protein engineered from a green-to-red photoconvertible fluorescent protein by circular permutation, and has been used in various optogenetic applications including precise control of protein localization and activity in cells. Upon violet light illumination, PhoCl undergoes a β-elimination reaction to be cleaved at the chromophore, resulting in spontaneous dissociation into a large empty barrel and a small C-terminal peptide. However, the structural determinants and the mechanism of the PhoCl photocleavage remain elusive, hindering the further development of more robust photocleavable optogenetic tools.

The systematic identification and functional characterization of noncanonical translation products, such as novel peptides, will facilitate the understanding of the human genome and provide new insights into cell biology. Here, we constructed a high-coverage peptide sequencing reference library with 11,668,944 open reading frames and employed an ultrafiltration tandem mass spectrometry assay to identify novel peptides. Through these methods, we discovered 8945 previously unannotated peptides from normal gastric tissues, gastric cancer tissues and cell lines, nearly half of which were derived from noncoding RNAs.

Riverine NO and N fluxes, key components of the global nitrogen budget, are known to be influenced by river size (often represented by average river width), yet the specific mechanisms behind these effects remain unclear. This study examined how environmental and microbial factors influenced sediment NO and N fluxes across rivers with varying widths (2.8 to 2,000 m) in China.

This study investigates the chemical complexity and toxicity of volatile organic compounds (VOCs) emitted from national petrochemical industrial parks and their effects on air quality in an industrial area of Nanjing, China. Field measurements were conducted from 1 December 2022, to 17 April 2023, focusing on VOC concentrations and speciations, diurnal variations, ozone formation potential (OFP), source identification, and associated health risks. The results revealed an average total VOC (TVOC) concentration of 15.

Background: Laparoscopic parenchyma-sparing hepatectomy (PSH) is an effective treatment for colorectal liver metastases (CRLMs), but ensuring the safety and radicality of the procedure, particularly for deep-seated tumors, remains challenging. Surgical navigation technologies such as augmented reality navigation (ARN) and indocyanine green fluorescence imaging (ICG-FI) are increasingly utilized to guide surgery, yet their efficacy for CRLMs is unclear. This study aims to evaluate the short- and long-term outcomes of ARN combined with ICG-FI-guided (ARN-FI) laparoscopic PSH for CRLMs.

In this study, we aimed to develop nanobodies targeting receptor tyrosine kinase-like orphan receptor 1 (ROR1) for cancer diagnosis and therapy. We immunized alpacas with ROR1, extracted RNA from their blood, and converted it to complementary DNA (cDNA) to amplify the VHH (variable domain of heavy-chain antibodies) sequence. This sequence was used to construct a phage library with a capacity of 8 ×10.

Article Synopsis
  • The study highlights the rarity and under-exploration of self-cleaving ribozymes in the human genome, focusing on LINE-1 and OR4K15.
  • Researchers found that these ribozymes consist of two short essential segments totaling only 35 and 31 nucleotides, making them the simplest known self-cleaving ribozymes.
  • The ribozymes exhibit unique structural characteristics, resembling lantern shapes, with significant differences in mutational impact compared to related ribozyme classes, suggesting they represent a primitive ribozyme structure.

Low-light image enhancement aims to enhance the visibility and contrast of low-light images while eliminating complex degradation issues such as noise, artifacts, and color distortions. Most existing low-light image enhancement methods either focus on quality while neglecting computational efficiency or have limited learning and generalization capabilities. To address these issues, we propose a Bilateral Enhancement Network with signal-to-noise ratio fusion, called BiEnNet, for lightweight and generalizable low-light image enhancement.

Article Synopsis
  • Prediction models help make medical decisions by estimating risks, advising high-risk individuals to undergo interventions while suggesting low-risk individuals avoid them.
  • Traditional models may overlook the complexities of interventions since they often assess risk at just one point in time, while in reality, decisions are made repeatedly and may change over time.
  • The article discusses how to formulate estimands for making better sequential predictions about interventions, using the example of choosing between vaginal delivery and cesarean section to inform future research and improve decision-making in clinical practice.

  • Hydraulic fracturing is crucial for extracting resources from tight volcanic rock reservoirs, which possess unique physical characteristics influenced by geological events like volcanic activity.
  • A study using true triaxial fracturing simulations revealed that these reservoirs have significant heterogeneity and can develop complex fracture networks, influenced by natural fractures, fluid viscosity, and fracturing fluid type.
  • Results showed that lower-viscosity fluids, like slickwater, enhance fracture formation, while supercritical carbon dioxide improves complexity due to its ability to permeate microfractures effectively.
