Changes of nuclear texture in mitotic cells of Drosophila melanogaster imaginal discs were studied. The distribution of voxels DAPI fluorescence intensities was used as the quantitative measure of the nuclear texture. The integral characteristics such as the portion of voxels with a given fluorescent signal level and autocorrelation of pixel intensities were used. We showed the nuclear texture has specific changes at different mitotic stages and this can be used for more precise staging of mitosis. Colchicines treatment pathologies, connected to abnormal mitoses, by nuclear-texture approach.

January 2025
Department of Galenic Pharmacy, Faculty of Pharmacy, Comenius University Bratislava, Odbojárov 10, SK-832 32 Bratislava, Slovakia.
The study focuses on the development of an in situ gelling dexamethasone (DEX) oromucosal formulation designed for the treatment of aphthous stomatitis. Three series of formulations were prepared; a first series containing DEX suspended, a second series containing DEX and, in addition, mint essential oil (EO), and a third series containing EO and DEX solubilized in propylene glycol (PG). In the composition, polymers in the role of mucoadhesive agent were interchanged (hydroxypropyl methylcellulose (HPMC), hydroxypropyl cellulose (HPC), hydroxyethyl cellulose (HEC), methyl cellulose (MC), carboxymethyl cellulose (CMC), and sodium carboxymethyl cellulose (NaCMC).

Objective: To investigate the predictive value of machine learning-based PET/CT radiomics and clinical risk factors in predicting interim efficacy in patients with follicular lymphoma (FL).
Methods: This study retrospectively analyzed data from 97 patients with FL diagnosed via histopathological examination between July 2012 and November 2023. Lesion segmentation was performed using LIFEx software, and radiomics features were extracted through the uAI Research Portal (uRP) platform, including first-order features, shape features, and texture features.
Cardiac Radiomics Analyses in Times of Photon-counting Computed Tomography for Personalized Risk Stratification in the Present and in the Future.

The need for effective early detection and optimal therapy monitoring of cardiovascular diseases as the leading cause of death has led to an adaptation of the guidelines with a focus on cardiac computed tomography (CCTA) in patients with a low to intermediate risk of coronary heart disease (CHD). In particular, the introduction of photon-counting computed tomography (PCCT) in CT diagnostics promises significant advances through higher temporal and spatial resolution, and also enables advanced texture analysis, known as radiomics analysis. Originally developed in oncological imaging, radiomics analysis is increasingly being used in cardiac imaging and research.

Department of Radiology, Section of Nuclear Medicine, Leiden University Medical Center, Leiden, The Netherlands.
Objective: Metastatic castration-resistant prostate cancer (mCRPC) is a heterogeneous disease with varying survival outcomes. This study investigated whether baseline PSMA PET/CT parameters are associated with survival and treatment response.
Methods: Sixty mCRPC patients underwent [F]PSMA-1007 PET/CT before treatment with androgen receptor-targeted agents (ARTAs) or chemotherapy.
Identification of PET/CT radiomic signature for classification of locally recurrent rectal cancer: A network-based feature selection approach.

Background: The modern approach to treating rectal cancer, which involves total mesorectal excision directed by imaging assessments, has significantly enhanced patient outcomes. However, locally recurrent rectal cancer (LRRC) continues to be a significant clinical issue. Identifying LRRC through imaging is complex, due to the mismatch between fibrosis and inflammatory pelvic tissue.
