Article Abstract
Drosophila melanogaster tumor models are growing in popularity, driven by the high degree of genetic as well as functional conservation to humans. The most common method to measure the effects of a tumor on distant organs of a human cancer patient is to use computed tomography (CT), often used in diagnosing cachexia, a debilitating cancer-induced syndrome most visibly characterized by loss of muscle mass. Successful application of high resolution micro-CT scanning of D. melanogaster was recently reported and we here present the segmentation of all visible larval organs at several stages of tumor development. We previously showed the strong expected reduction in muscle mass as the tumor develops, and we here report a surprisingly strong reduction also in gut and Malpighian tubules (kidney) volume. Time-point of tumor development was found to have a stronger correlation to cachectic organ volume loss than tumor volume, giving support to the previously proposed idea that tumor size does not directly determine degree of cachexia.

YOLOv12 Algorithm-Aided Detection and Classification of Lateral Malleolar Avulsion Fracture and Subfibular Ossicle Based on CT Images: A Multicenter Study.

Background: Lateral malleolar avulsion fracture (LMAF) and subfibular ossicle (SFO) are distinct entities that both present as small bone fragments near the lateral malleolus on imaging, yet require different treatment strategies. Clinical and radiological differentiation is challenging, which can impede timely and precise management. On imaging, magnetic resonance imaging (MRI) is the diagnostic gold standard for differentiating LMAF from SFO, whereas radiological differentiation on computed tomography (CT) alone is challenging in routine practice.

This study aimed to investigate the age-related alterations in mesial roots of mandibular first molar in terms of root canal curvature values, dentin thickness, interorifice distance, deviation from apical foramen, and location of apical foramen using a three-dimensional curvature measurement method and micro-computed tomography (micro-CT). Forty-five mesial roots of mandibular first molars from three age groups (Group 1: ≤ 30 years, Group 2: 31-59 years, Group 3: ≥ 60 years) were scanned using micro-CT. The central axis of each mesiobuccal and mesiolingual canal was analyzed using cubic B-spline curves to calculate canal curvature.

Purpose: To investigate the images and treatment differences for Type IIIa atlantoaxial rotary dislocation (AARD) by comparing the imaging characteristics of patients with Type III and Type IIIa AARD.
Methods: The present study retrospectively analyzed a cohort of 35 patients who underwent posterior C1-C2 intra-articular fusion due to AARD from our hospital database. Among them, 23 patients were diagnosed with Type III AARD, while the remaining 12 patients were diagnosed with Type IIIa AARD.

The development of pulmonary hypertension (PH) after splenectomy is one of the recently controversial issues. This study aims to investigate whether splenectomy itself is an independent risk factor for the development of PH or if the primary contributor to PH development is the underlying condition that necessitated splenectomy. This study was conducted prospectively.

Purpose: Crohn's disease (CD) is characterized by enteric inflammation, often resulting in strictures and penetrating complications, which may alter patient management prior to the initiation of biologic therapy. Our aim is to assess the frequency of missed stricturing and internal penetrating complications in CD patients on computed tomography enterography (CTE) and magnetic resonance enterography (MRE) performed prior to anti-TNF therapy.
Methods: We retrospectively reviewed patients from two tertiary centers who underwent CTE\MRE within six months before starting anti-TNF therapy.
