Photothermal therapy (PTT) is a promising approach for treating glioblastoma multiforme (GBM) with minimal invasiveness and favorable outcomes. Conjugated polymers as photothermal agents offer stability, biocompatibility, and adjustable absorption capacity. However, existing polymers face limitations in achieving high photothermal conversion efficiency and strong absorbance in the near-infrared (NIR) region, posing a risk of damaging healthy tissues surrounding GBM during precise PTT.

Article Synopsis
  • Rapid diagnosis of mental health issues in college students is vital, leading to the development of a machine learning model aimed at simplifying the University Personality Inventory (UPI) while addressing its limitations.
  • The study involved administering the UPI to 5,155 students and comparing three machine learning models, finding the Random Forest model to have the highest accuracy at 89.4% while reducing the UPI items from 60 to just 6.
  • The research suggests that this simplified tool can help students quickly assess their mental health, promoting timely intervention and better overall mental well-being.

Earthen sites in China are widely exposed to freeze-thaw environments. There is a lack of knowledge about the spatial distribution patterns of freeze-thaw deterioration and environments, as well as preventive conservation strategies and subsequent refined research on the freeze-thaw deterioration of earthen sites. In this study, the freeze-thaw deterioration process of earthen sites was divided into two periods.

π-stacking interaction, as a fundamental type of intermolecular interaction, plays a crucial role in generating new functional molecules, altering the optoelectronic properties of materials, and maintaining protein structural stability. However, regulating intermolecular π-π interactions at the single-molecule level without altering the molecular conformation as well as the chemical properties remains a significant challenge. To this end, conductance measurement with thousands of single molecular junctions employing a series of aromatic molecules, we demonstrate that the π-π coupling between neighboring aromatic molecules with rigid structures in a circuit can be greatly enhanced by increasing the bias voltage.

Article Synopsis
  • * This enhancement leads to higher transmission coefficients and electrical conductance at the Fermi energy, as well as a steep transmission function that increases the Seebeck coefficient.
  • * Altering electrode distances and varying heteroatom positions further confirms the robustness of the edge substitution effect, suggesting its potential for developing efficient thermoelectric devices.

Photothermal therapy (PTT) using near-infrared (NIR) conjugated polymers as photosensitizers has exhibited enormous potential for tumor treatment. However, most NIR conjugated polymers have poor therapeutic efficacy due to their faint absorbance in the NIR region and low photothermal conversion efficiency (PCE). Herein, a valuable strategy for designing NIR polymeric photosensitizer PEKBs with an enhanced PCE accompanied by strong NIR absorbance is proposed by means of inserting TPA-AQ as a thermally activated delayed fluorescence unit into a polymeric backbone.

Video object detection is a fundamental and important task in computer vision. One mainstay solution for this task is to aggregate features from different frames to enhance the detection on the current frame. Off-the-shelf feature aggregation paradigms for video object detection typically rely on inferring feature-to-feature (Fea2Fea) relations.

Article Synopsis
  • - The study investigated the role of DNA methylation, an epigenetic marker, in tomato breeding by analyzing wild tomatoes, landraces, and cultivars through whole-genome sequencing and metabolic profiling, identifying 8,375 differentially methylated regions (DMRs).
  • - It was found that DNA methylation levels decrease from domestication to improvement, with over 20% of DMRs overlapping with selective sweeps and many being linked to adjacent SNPs rather than being directly associated with them.
  • - The research identified 13 candidate genes and a more detailed polyphenol biosynthetic pathway, showcasing that DNA methylation can enhance our understanding of metabolite diversity in plants alongside traditional SNP profiling.

Tomato () is the most valuable fruit and horticultural crop species worldwide. Compared with the fruits of their progenitors, those of modern tomato cultivars are, however, often described as having unsatisfactory taste or lacking flavor. The flavor of a tomato fruit arises from a complex mix of tastes and volatile metabolites, including sugars, acids, amino acids, and various volatiles.

Purpose: To investigate the risk factors for thoracic ossification of the ligamentum flavum (TOLF), especially the relationship between BMI and TOLF.

Methods: A total of 856 individuals consisting of 326 controls without ossification of spinal ligaments and 530 TOLF inpatients who underwent thoracic spine decompression surgery at our hospital between January 2013 and September 2020 were included. All subjects were classified into 4 grades: Grade 0) control; Grade 1) single-segment TOLF; Grade 2) multi-segment TOLF; and Grade 3) TOLF combined thoracic ossification of the posterior longitudinal ligament (T-OPLL).
