Regardless of the reconstruction surgery used, the fundamental concepts of visceral reconstruction are based on the vascular support needed for the substituting graft. The vascular factor is the main element of any reconstruction technique, as an underlying condition for the visceral material stretch and, along with other factor, for the suture safety. In the case of the stomach, a consistent vascular flow and the minimal vascular anatomy variations are the first theoretical argument. A second argument is based on the intraparietal vascular network features allowing for supplementing visceral perfusion as the blood flow is stopped in one or more pediculi. Graft hypoperfusion is, however, a potential cause of failure, and the most frequently invoked complication is, therefore, a high risk of anastomosis fistulae. A series of modern techniques - arteriography data for the pre-operative vascular reconstruction or Doppler laser fluorometry intraoperative assessments, graft oximetry, laser speckle (spot) scan or the use of indocyanine green staining (ICG) - represent methods of early determination of the gastric graft perfusion/microperfusion quality used in reducing such risks. The doubts regarding the gastric perfusion mandate the use of vascular augmentation techniques. If such techniques are not used, the final outcome is uncertain and difficult to correct.

Traditional methods of plasmid delivery, including viral vectors, lipofection, and electroporation, are widely used for gene editing but have limitations, such as cellular toxicity, limited transfection efficiency in primary cells, and nonspecific side effects. Here, we report the development of nucleus pulposus cell (NPC)-mimicking nanoparticles (HIF1A@NNP) with an NPC membrane as the shell and pcDNA3.1-rHIF1A encapsulated in the core via extrusion.

Background: The use of plaque modification techniques during percutaneous coronary interventions (PCI) has increased. However, these procedures are linked to higher contrast volume and hypotensive episodes, which are risk factors for acute kidney injury (AKI). This study examined the effects of various plaque modification techniques on AKI after PCI.

IgA nephropathy (IgAN), the most prevalent primary glomerulonephritis worldwide, carries a considerable lifetime risk of kidney failure. The etiology of IgAN, however, remains incompletely understood, and effective treatment is lacking. Although the multihit model effectively identifies key steps in IgAN development and, to date, provides the best description of IgAN pathogenesis, it remains under development to fully capture the complexity of immune system dysregulation.

A modified thoracodorsal artery lateral branch (TDAL) chimeric flap was developed using dual-energy computed tomography (CT) angiography data of perforators to explore the anatomical characteristics and postoperative outcomes of TDAL flaps in complex maxillofacial defect repair. TDAL flaps were harvested from patients with locally advanced oral cancer. Preoperative perforator detection was performed with dual-energy CT angiography.

Chronic aortic dissection is a complex disease with a heterogenous clinical course. Specialised imaging is necessary for the long-term surveillance of this disease to identify patients who meet the criteria for intervention, and to monitor surgically treated patients for complications. Whilst computed tomography and magnetic resonance imaging are the most widely utilised modalities, providing a high degree of anatomical detail and reproducible aortic measurements, they are not without significant limitations.
