Background: Numerous cone beam computed tomography (CBCT) studies have been done to analyze the canal anatomy of maxillary molars. However, research on comparison of symmetry in contralateral molars in the Indian population is limited.
Aim: The aim of this study is to identify and assess the variations in the internal anatomy based on Vertucci's classification and to compare the prevalence of additional canals in contralateral maxillary first molar (Mx 1 M) and maxillary second molar (Mx 2 M) using CBCT.
Settings And Design: A total of 120 small and medium field of view CBCT images with Mx1M and Mx2M were collected and retrospectively evaluated.
Materials And Methods: Coronal, sagittal, and axial views of CBCT scans were analyzed by scrolling the scans, adjusting the contrast and brightness, and magnifying the canal configuration, along with additional canals and symmetry were identified and recorded.
Statistical Analysis: Data were analyzed using McNemar's test and Chi-square test.
Results: Both Mx1M and Mx2M showed bilateral symmetry in the mesiobuccal root with Type I canal anatomy in 86.1% and 97.8%, respectively. The MB2 canal was evident in 34.1% of Mx1M and 8.4% of Mx2M.
Conclusion: Variations such a single-rooted and two-rooted teeth in Mx2M with Type I Vertucci's canal anatomy were seen. The MB2 canal was the only additional canal found.

The tuna keel is a mechanosensory structure.
iScience

Museum of Comparative Zoology, Harvard University, Cambridge, MA 02138, USA.
Tunas are high-performance pelagic fishes of considerable economic importance and have a suite of biological adaptations for high-speed locomotion. In contrast to our understanding of tuna body and muscle function, mechanosensory systems of tuna are poorly understood. Here we present the discovery of a remarkable sensory lateral line canal within the bilateral tuna keels with tubules that extend to the upper and lower keel surfaces.

Department of Neurology, Second Affiliated Hospital of Xuzhou Medical University, Xuzhou, Jiangsu, China.
Objective: To investigate changes of brain functional activity in patients with acute unilateral vestibulopathy (AUVP) using functional magnetic resonance imaging (fMRI).
Methods: We studied 32 AUVP patients and 30 healthy controls (HC) who received resting-state fMRI scanning. Methods of voxel-based amplitude of low-frequency fluctuation (ALFF) and seed-based functional connectivity (FC) were adopted to compare the difference in brain function between the two groups.
New insights into the goals of transgender male versus non-binary individuals considering metoidioplasty and phalloplasty gender-affirming surgery.
J Sex Med
January 2025
Department of Surgery, Section of Urology, Dartmouth Hitchcock Medical Center, Lebanon, NH 03756, United States.
Background: Understanding patient goals for metoidioplasty and phalloplasty gender-affirming surgery (MaPGAS) is paramount to achieving satisfactory, preference-sensitive outcomes, yet there is a lack of understanding of MaPGAS priorities and how these may vary between transgender men and non-binary individuals assigned female at birth (AFAB).
Aim: To understand the surgical goals of transgender men and non-binary individuals AFAB considering MaPGAS.
Methods: An online survey was created following literature review and qualitative interviews and distributed via social media and a community health center to participants AFAB aged ≥18 years who had considered but not yet undergone MaPGAS.
Effectiveness of Root Canal Irrigation and Dressing for the Treatment of Asymptomatic Apical Periodontitis: A Systematic Review Assessing Complementary Timeframes.

Sodium hypochlorite (NaOCl), ethylenediaminetetraacetic acid (EDTA), and calcium hydroxide (Ca(OH)) are used in root canal treatment. However, further research is needed to assess their effectiveness at time points not considered in previous guidelines. This review complements the systematic review by Rossi-Fedele and Rödig (2023) by considering time points excluded by the latter.

However, most simulators lack the ability to mimic the differing anatomic complexities between patients, such as variable external auditory canal (EAC) size. We developed a novel low-cost, medium-fidelity 3-dimensional-printed PET simulator with different EAC sizes to better reflect procedure complexity.
