A new technique for ligating vessels and similar structures that offers more security is described. The aim of the study was to test whether this hypothesis was correct. Six different types of knots, including the one described in this article were compared by a strength-testing study. The knots were tied on a silicon tube through which a constant air flow of 795.10 mmHg of pressure circulated. Tension of 2 kg was then applied to both loose ends of the suture filament (polyglyconate n degrees 1 gauge) for 25 seconds. Then, 15 seconds after the tension was released an overpressure of 2250.31 mmHg was applied to the system. Two computerized pressure sensors were applied to both ends of the tube. The newly described knot reached the highest strangulating force (997.63 mmHg) and had the highest resistance to slippage. From these results, we conclude that the new knot is far more secure for vessel and duct ligature and that it represents a new and useful tool for surgeons in both open and laparoscopic surgery.

Background: Hindfoot endoscopy is an effective treatment for posterior ankle impingement syndrome (PAIS) and flexor hallucis longus (FHL) tendon disorders. However, FHL tendoscopy, especially from the posteromedial portal, carries a risk of tibial nerve damage. A needle-arthroscopic system with a 1.

This research was conducted to determine the relationship between plant defense responses and the extent of treatment applied to either the aerial parts or roots of the plant. The experimental treatments included different methods of application (spraying versus soil drenching), varying treatment areas (one-sixth, one-third, half, or all of the plant's aerial parts and roots) with SA, and infecting the plants with root-knot nematodes. Evaluation of plant growth and nematode pathogenicity indices in the greenhouse section, HO accumulation rate, and phenylalanine ammonia lyase enzyme activity (in aerial parts and roots) were carried out in biochemical experiments.

Background: Total laparoscopic hysterectomy (TLH) is nowadays the standard to treat benign and malignant disease occurring in the uterus, but the number of robotic-assisted surgeries is increasing worldwide. To facilitate the handling of sutures in a bi- and tri-dimensional plane, a new type of suture material has been developed, named barbed sutures, which are in use in different indications. In comparison to conventional suture materials, the barbs anchor the suture in the tissue, provide tissue approximation and prevent slippage without the need for knot tying.

Background: The primary treatment for cervical insufficiency is cervical cerclage (mechanical support) with vaginal progesterone (biochemical support). Cerclage is a surgical procedure that mechanically increases the tensile capacity of the cervix. Therefore, it is necessary to analyse the effects of cerclage from a mechanical point of view.
