Quantifying intratumoral heterogeneity within sub-regions to predict high-grade patterns in clinical stage I solid lung adenocarcinoma.
BMC Cancer
January 2025
Department of Radiology, Xiangtan Central Hospital, Xiangtan, 411000, P. R. China.
Background: This study aims to quantify intratumoral heterogeneity (ITH) using preoperative CT image and evaluate its ability to predict pathological high-grade patterns, specifically micropapillary and/or solid components (MP/S), in patients diagnosed with clinical stage I solid lung adenocarcinoma (LADC).
Methods: In this retrospective study, we enrolled 457 patients who were postoperatively diagnosed with clinical stage I solid LADC from two medical centers, assigning them to either a training set (n = 304) or a test set (n = 153). Sub-regions within the tumor were identified using the K-means method.
Semi-field experiments reveal contrasted predation and movement patterns of aquatic macroinvertebrate predators of Anopheles gambiae larvae.

Background: Members of the Anopheles gambiae complex are major malaria vectors in sub-Saharan Africa. Their larval stages inhabit a variety of aquatic habitats in which, under natural circumstances, they are preyed upon by different taxa of aquatic macroinvertebrate predators. Understanding the potential impact of predators on malaria vector larval population dynamics is important for enabling integrated local mosquito control programmes with a stronger emphasis on biocontrol approaches.

Swimming is a popular sport with several health benefits, but its effects on bone quality are controversial possibly due to distinct effects on different anatomical regions. Our aim was to investigate the effect of 8-month swimming on bone growth, mass, geometry, trabecular microarchitecture and osteocyte density of the lumbar vertebrae, femur and tibia of male rats. Wistar rat models were assigned to either a swimming (n = 10; 2h/d, 5 d/week) or a physically active control group (n = 10) for 8 months, after which they were sacrificed and their lumbar vertebrae, femur and tibia assessed for bone mass, cortical geometry, trabecular microarchitecture and osteocyte density through µ-CT and histology.

Department of Endodontics, Faculty of Odontology, Malmö University, 205 06 Malmö, Sweden.
To compare pain characteristics, impact of pain and characteristics of patients with painful root-filled teeth with and without signs of inflammatory dental disease. This cross-sectional study was performed in the Public Dental Health services, Region Örebro County, Sweden. Adult patients with ≥1 root-filled tooth identified at their regular check-up were included and assigned to one of two groups; those with ≥1 sign of inflammatory dental disease (DD+) and those without any such sign (DD-).

School of Physical Education and Sports Science, Soochow University, Suzhou 215021, China. Electronic address:
Background: Medical training therapy (MTT) is an advanced, individualized rehabilitation approach that integrates multiple methods to improve physical function. It is widely applied to rehabilitate sports injuries. This randomized study evaluated MTT's effects on physical injury rehabilitation, mental function, and athletic performance in elite rock climbers.
