The method of creation of compressive terminal colon anastomosis with implants of TN-10 titanium nikelid was developed. Experimental studies carried out on 60 mongrel dogs demonstrated higher physical strength and biological containment of these anastomoses compared with manual and mechanical ones. Regeneration completed earlier after surgery and was accompanied by less inflammation. Clinical study was carried out in 54 patients. There were no lethal outcomes, insufficiency of anastomosis was seen in 1 (1.9%) case.

Fixed-point thickness measurement is commonly used in corrosion detection within petrochemical enterprises, but it suffers from low detection efficiency for localized thinning, limitations regarding measurement locations, and high equipment costs due to insulation and cooling layers. To address these challenges, this paper introduces a wireless passive ultrasonic thickness measurement technique based on a pulse compression algorithm. The research methodology encompassed the development of mathematical and circuit models for single coil and wireless energy transmission, the proposal of a three-terminal wireless energy mutual coupling system, and the establishment of a finite element model simulating the ultrasonic body wave thickness measurement and wireless energy transmission system.

Transarterial embolization (TAE) is an image-guided, minimally invasive procedure for treating various clinical conditions by delivering embolic agents to occlude diseased arteries. Conventional embolic agents focus on vessel occlusion but can cause unintended long-term inflammation and ischemia in healthy tissues. Next-generation embolic agents must exhibit biocompatibility, biodegradability, and effective drug delivery, yet some degradable microspheres degrade too quickly, leading to the potential migration of fragments into distal blood vessels causing off-target embolization.

This article introduces an innovative multipurpose system that integrates a solar power plant with a coastal wind farm to generate refrigeration for refinery processes and industrial air conditioning. The system comprises multiple wind turbines, solar power plants, the Kalina cycle to provide partial energy for the absorption refrigeration cycle used in industrial air conditioning, and a compression refrigeration cycle for propane gas liquefaction. An extensive energy and exergy analysis was conducted on the proposed system, considering various thermodynamic parameters such as the solar power plant's energy output, the absorption chiller's cooling load, the electricity generated by the turbines, the wind turbines' power output, and the energy efficiency and exergy of each cycle within the system.

Objectives: Information from indocyanine green (ICG) lymphography (ICG-L) can be used to guide an individual's lymphedema therapy plan. However, the mechanisms for this clinical translation are not well described. This study proposes a novel clinical decision support tool for translating ICG-L findings into individualized lymphedema therapy plans and describes subsequent changes in plan features of manual lymphatic drainage and compression.

Background: Rotational vertebral artery occlusion, or bow hunter's syndrome (BHS), is a rare but clinically important cause of vertebrobasilar insufficiency. Extrinsic compression of the artery is usually caused by osteophytes, fibrous bands, or lateral disc herniation and typically occurs in the setting of anatomical variations, leading to dynamic compromise of the posterior circulation. Neoplastic causes of BHS are rare.
