Background/aim: Surgeons often face with the problem when selecting a reconstructive method for nasal skin defects. The aim of this study was to determine functional and aesthetic character-istics of different reconstructive methods used for skin defects in different regions of the nose.
Methods: The study involved 44 patients with basocellular carcinoma in nasal area. The nasal skin was divided into four subunits: the tip, the alar lobules, the side-walls and the dorsum. The average skin defect size was 10 mm in diameter. Local flaps and full thickness skin grafts were used in the study. We analyzed the functional and esthetic results of dif-ferent reconstructive methods used for nasal defects in different regions of the nose 12 months after the surgery.
Results: The study shows that different reconstructive methods produce dif-ferent functional and esthetic results in the same nasal subunits and that the same reconstructive method produces different re-sults in different nasal subunits.
Conclusions: Estimation the postoperative functional and esthetic characteristics of different reconstructive methods is one of the basic preconditions of suc-cessful reconstruction.

Background: Rheumatoid arthritis (RA) is a chronic autoimmune disease which afflicts about nearly 1% of global population. RA results in synovitis and cartilage/bone damage, even disability which aggravates the health burden. Many drugs are used to relieve RA, such as glucocorticoids (GCs), non-steroidal anti-inflammatory drugs (NSAIDs), and disease-modifying anti-rheumatic drugs (DMARDs) in the clinical treatment.

Background: Conventional hip joint MRI scans necessitate lengthy scan durations, posing challenges for patient comfort and clinical efficiency. Previously, accelerated imaging techniques were constrained by a trade-off between noise and resolution. Leveraging deep learning-based reconstruction (DLR) holds the potential to mitigate scan time without compromising image quality.

Purpose: It was noticed that anterior choroidal artery (AChoA) aneurysms appear to rupture at relatively smaller sizes compared with aneurysms in other intracranial locations, based on anecdotal clinical experience. We therefore aimed to compare ruptured AChoA aneurysms with other ruptured aneurysms in other intracranial locations, pertaining to aneurysm dimensions. This may help in finding out if the rupture risk stratification, based on the amalgamation of aneurysms of multiple locations in one group, precisely estimates aneurysm rupture risk.

The brain is composed of a dense and ramified vascular network of arteries, veins and capillaries of various sizes. One way to assess the risk of cerebrovascular pathologies is to use computational models to predict the physiological effects of reduced blood supply and correlate these responses with observations of brain damage. Therefore, it is crucial to establish a detailed 3D organization of the brain vasculature, which could be used to develop more accurate in silico models.

Electron tomography can provide additional morphological information not easily obtained by conventional transmission electron microscopy of thin sections. It uses a goniometer stage in the electron microscope to tilt the specimen and collect a series of 2D images from different orientations, which are combined to provide a 3D volume tomogram and a colored reconstruction of the morphological feature(s) of interest. Here we describe the protocols for its use in visualizing changes in organelle morphology after depletion of the SNARE proteins VAMP7 and VAMP8 and to study VAMP7 localization on endolysosomes/lysosomes.
