Human brains typically grow through development, then remain the same size in adulthood, and often shrink through age-related degeneration that induces cognitive decline and impaired functionality. In most cases, however, the neural and organismal changes that accompany shrinkage, especially early in the process, remain unknown. Paralleling neurodegenerative phenotypes, the Eurasian common shrew Sorex araneus, shrinks its brain in autumn through winter, but then reverses this process by rapidly regrowing the brain come spring. To identify the molecular underpinnings and parallels to human neurodegeneration of this unique brain size change, we analyzed multi-organ, season-specific transcriptomics and metabolomic data. Simultaneous with brain shrinkage, we discovered system-wide metabolic shifts from lipid to glucose metabolism, as well as neuroprotection of brain metabolic homeostasis through reduced cholesterol efflux. These mechanisms rely on a finely tuned brain-liver crosstalk tha...

中国劳动力动态调查
“中国劳动力动态调查” （China Labor-force Dynamics Survey，简称 CLDS）是“985”三期“中山大学社会科学特色数据库建设”专项内容，CLDS的目的是通过对中国城乡以村/居为追踪范围的家庭、劳动力个体开展每两年一次的动态追踪调查，系统地监测村/居社区的社会结构和家庭、劳动力个体的变化与相互影响，建立劳动力、家庭和社区三个层次上的追踪数据库，从而为进行实证导向的高质量的理论研究和政策研究提供基础数据。

MMOral
MMOral是一个针对全景X光片解读的大规模多模态指令数据集和基准。它包括20,563张带有1.3百万条指令跟随实例的注释图像，涵盖了多种任务类型，如属性提取、报告生成、视觉问答和基于图像的对话。此外，我们还提出了MMOral-Bench，这是一个涵盖牙科五个关键诊断维度的综合评估套件。我们评估了64个LVLMs在MMOral-Bench上的表现，发现即使是表现最好的模型GPT-4o，也只能达到41.45%的准确率，这揭示了当前模型在这一领域的显著局限性。为了促进该特定领域的发展，我们还提出了OralGPT，它使用我们精心策划的MMOral指令数据集对Qwen2.5-VL-7B进行监督微调。值得注意的是，一个SFT周期就为LVLMs带来了显著的性能提升，例如，OralGPT表现出24.73%的改进。MMOral和OralGPT都具有作为智能牙科关键基础的巨大潜力，并使牙科领域中的多模态AI系统更具临床意义。数据集、模型、基准和评估套件可在上述网址获取。

Data From NSCLC-Radiomics
This collection contains images from 422 non-small cell lung cancer (NSCLC) patients. For these patients pretreatment CT scans, manual delineation by a radiation oncologist of the 3D volume of the gross tumor volume and clinical outcome data are available. This dataset refers to the Lung1 dataset of the study published in Nature Communications. In short, this publication applies a radiomic approach to computed tomography data of 1,019 patients with lung or head-and-neck cancer. Radiomics refers to the comprehensive quantification of tumour phenotypes by applying a large number of quantitative image features. In present analysis 440 features quantifying tumour image intensity, shape and texture, were extracted. We found that a large number of radiomic features have prognostic power in independent data sets, many of which were not identified as significant before. Radiogenomics analysis revealed that a prognostic radiomic signature, capturing intra-tumour heterogeneity, was associated with underlying gene-expression patterns. These data suggest that radiomics identifies a general prognostic phenotype existing in both lung and head-and-neck cancer. This may have a clinical impact as imaging is routinely used in clinical practice, providing an unprecedented opportunity to improve decision-support in cancer treatment at low cost. The dataset described here (Lung1) was used to build a prognostic radiomic signature. The Lung3 dataset used to investigate the association of radiomic imaging features with gene-expression profiles consisting of 89 NSCLC CT scans with outcome data can be found here: NSCLC-Radiomics-Genomics.
