Rationale And Objectives: The study aimed to evaluate demographic and radiological characteristics of breast incidentalomas found on 18-fluorodeoxyglucose Positron Emission Tomography-Computed Tomography (F-FDG PET-CT) performed for extramammary indications.
Materials And Methods: A total of 12633 F-FDG PET-CT scans performed between January 1, 2018 and January 1, 2024, were retrospectively reviewed. Breast incidentalomas that had undergone breast imaging, tissue diagnosis, or at least 2-year radiological follow-up were included.
'Opponent channels model' (OCM) is the widely accepted model for cortical representation of sound lateralization. Stimulus-specific 'release from adaptation' (RFA) in cortical responses has been used in previous studies to test the predictions of this model. However, these attempts were shown to be prone to confounds of spurious responses such as those to auditory motion and sound onset.

- The study focuses on an 8-year-old Labrador dog that suffered from degenerative skeletal changes after being involved in a road traffic accident, eventually leading to its death despite medical interventions.
- Researchers conducted a CT scan on the dog’s humerus and discovered osteophytes, or bone spurs, that formed a almost complete ring structure, which suggested issues related to joint mobility.
- During the dissection of the bones, they found a thin membrane covering the supratrochlear foramen that the CT scan did not detect, indicating limitations in imaging techniques for identifying certain soft tissue abnormalities.
Motivation: Phylogenetic reconstruction is a fundamental problem in computational biology. The Neighbor Joining (NJ) algorithm offers an efficient distance-based solution to this problem, which often serves as the foundation for more advanced statistical methods. Despite prior efforts to enhance the speed of NJ, the computation of the n2 entries of the distance matrix, where n is the number of phylogenetic tree leaves, continues to pose a limitation in scaling NJ to larger datasets.

- Noise-induced cochlear synaptopathy leads to the permanent loss of synapses between inner hair cells (IHCs) and spiral ganglion neurons (SGNs) without affecting overall hearing thresholds.
- In experiments with C57BL/6 N mice exposed to various noise levels, significant changes in auditory brainstem responses (ABRs) were observed, indicating loss of IHC synaptic connections and impaired hearing ability over time.
- The study revealed that while the number of synaptic pairs decreased significantly, the IHC postsynapses were more resilient than the presynaptic ribbons, highlighting the vulnerability of these synapses to noise trauma at high decibel levels.
