Colorectal cancer is one of the most common causes of cancer mortality worldwide, and innovative drugs for the treatment of colorectal cancer are continually being developed. 5-Fluorouracil (5-FU) is a common clinical chemotherapeutic drug. Acquired resistance to 5-FU is a clinical challenge in colorectal cancer treatment.

Cross-Modal Graph Contrastive Learning with Cellular Images.

Constructing discriminative representations of molecules lies at the core of a number of domains such as drug discovery, chemistry, and medicine. State-of-the-art methods employ graph neural networks and self-supervised learning (SSL) to learn unlabeled data for structural representations, which can then be fine-tuned for downstream tasks. Albeit powerful, these methods are pre-trained solely on molecular structures and thus often struggle with tasks involved in intricate biological processes.

Occupational Factors Associated With Burnout Among a Sample of 9-1-1 Public Safety Telecommunicators in Washington State.

Introduction: This study aimed to investigate occupational factors associated with burnout among a sample of 9-1-1 public safety telecommunicators (PSTs).

Methods: An online survey measuring organizational factors (ie, perceived visibility and inclusion in the agency, respectful culture, leadership support, perceived gratitude, and coworker conflict); job characteristic s (ie, work-life integration, overtime, salary satisfaction, and job meaningfulness); and burnout, demographic, and call center characteristics was emailed to a sample of PSTs.

Analysis: Descriptive, bivariate, and multiple linear regression analyses were used to characterize the sample and investigate relationships among variables.

Structure, Regulation, and Significance of Cyanobacterial and Chloroplast Adenosine Triphosphate Synthase in the Adaptability of Oxygenic Photosynthetic Organisms.

In cyanobacteria and chloroplasts (in algae and plants), ATP synthase plays a pivotal role as a photosynthetic membrane complex responsible for producing ATP from adenosine diphosphate and inorganic phosphate, utilizing a proton motive force gradient induced by photosynthesis. These two ATP synthases exhibit similarities in gene organization, amino acid sequences of subunits, structure, and functional mechanisms, suggesting that cyanobacterial ATP synthase is probably the evolutionary precursor to chloroplast ATP synthase. In this review, we explore the precise synthesis and assembly of ATP synthase subunits to address the uneven stoichiometry within the complex during transcription, translation, and assembly processes.

Molecular and immune characterization of Chinese early-stage non-squamous non-small cell lung cancer: a multi-omics cohort study.
