The data of B-scanning of 120 eyes with various diseases are analyzed. The authors pay special attention to the morphology of posterior segments of the vitreous and posterior hyaloid detachment and to relationship between tissues of the posterior segment and the type of pathological process. Sonograms with certain nosological entities are described and deciphered.

Objective: To evaluate the pharyngeal airway dimensions and regional pharyngeal adipose distribution in the young adult minipig model.
Materials And Methods: Eight 7-8-months-old Yucatan minipigs, half male and female, were sedated and placed prone to scan the pharyngeal region. Magnetic resonance imaging (MRI) was performed using dynamic turbo-field echo (TFE)-sequence with respiratory gating and adipose-weighted sequence.

The subsuperior segment (S∗), as an atypical pulmonary segment, is located between the superior and posterior basal segments. Many thoracic surgeons have no experience with anatomical segmental resection of S∗. We present a case of the posterior approach of left S∗ segmentectomy.

We describe a rare but interesting complication of totally endoscopic robotic mitral valve repair in a patient with severe mitral regurgitation. The mitral valve was repaired robotically by standard techniques, and the intraoperative transesophageal echocardiogram demonstrated no residual mitral regurgitation. However, there was unexpected hypokinesia of the posterior and lateral walls of the left ventricle, with subsequent electrocardiography showing acute ST elevations of the lateral segment.

The human cerebral cortex is known for its hemispheric specialization, which underpins a variety of functions and activities. However, it is not well understood if similar lateralization exists within the deep gray matter nuclei, such as the basal ganglia (BG) and thalamus, and their associated arteries, including the lenticulostriate arteries (LSAs). To explore this, we analyzed images from 7T MRI scans of 40 healthy young individuals.

Purpose: The purpose of this study was to characterize whether pulsed ultrasound (PUS) affects transscleral drug delivery.
Methods: Fluorescein sodium (NaF, 376 Da) and fluorescein isothiocyanate-conjugated dextran 40 (FD-40, 40 kDa) were used as model drugs. Human sclera grafts were placed in modified Franz diffusion cells and were treated by PUS (1 megahertz [MHz], 0.
