BACKGROUNDS With respect to the knife's design in colorectal endoscopic submucosal dissection (ESD), diameter, water jet function, and electric power are important because these relate to efficient dissection. In this study, we analyzed a novel, narrow ball tip-typed ESD knife with water jet function (Flush knife BT-S, diameter: 2.2 mm, length: 2000 mm, Fujifilm Co., Tokyo, Japan) compared to a...

The integration of spray drying and agglomeration offers significant advantages, such us continuous production with lower energy consumption. However, it is a knife-edge process narrow operating window limited degrees freedom that decide between successful fluidized bed blockage due to excessive moisture. In this contribution, factors influencing the spray-through skim milk powder as model syst...

BACKGROUND AND STUDY AIMS  Few studies have directly compared endo-knives for endoscopic submucosal dissection (ESD) in humans. We compared the performances of the Mucosectom2 and SB knife Jr. PATIENTS AND METHODS  Two trainee endoscopists performed ESD of 36 lesions in this prospective, randomized controlled trial. Mucosal incision with a 1.5-mm Dual knife and submucosal dissection using the...

submucosal dissection (ESD) is a minimally invasive treatment and enables en bloc resection of large le-sions. However, ESD is a technically demanding and time-consuming procedure. 1 Here, we report a " two-sword fencing " technique with an injection needle and an ESD knife. A 74-year-old man presented with a laterally spreading tumor (LST), 7 cm in diameter, on the right wall of the rectum, an...

BACKGROUND The initial aim was to determine the rate of pathologic tissue damage when dissecting the rat sciatic nerve with either bipolar forceps or low-temperature tripolar plasma knife. The second aim was to determine the safety and effectiveness of the plasma knife during parotid surgery. METHODS A prospective, randomized, single-blind study was performed on 40 rat sciatic nerves dissecte...

OBJECTIVE To report the first case of using the insulation-tipped diathermic knife 2 (IT knife-2) for the treatment of postintubation tracheal stenosis. CLINICAL PRESENTATION AND INTERVENTION A 71-year-old female patient with a history of endotracheal intubation 3 years earlier presented with throat discomfort, gross wheezing and dyspnea. Chest imaging and bronchoscopy demonstrated a strand-l...

AIM Giant arteriovenous malformations (i.e., those greater than 6 cm maximum diameter or volume > 33 cc) are difficult to treat and often carry higher treatment morbidity and mortality rates. In our study, we reviewed the angiographic results and clinical outcomes for 11 patients with giant arteriovenous malformations who were treated between 1994 and 2012. MATERIAL AND METHODS The patients s...

purpose: to study early treatment outcomes and complications of gamma knife radiosurgery (gkrs) in patients with functional and nonfunctional adenomas. methods: one hundred patients with a pituitary adenoma who were treated between 2011 and 2014 at iran gamma knife center were studied. the patients were followed up at least 2 years. radiosurgery was performed using the leksell gamma unit. the m...

Male hamsters in which the stria terminalis (ST) had been interrupted either by electrolytic lesions or knife cuts, or normal control males, received iontophoretic injections of horseradish peroxidase in either the bed nucleus of the stria terminalis (BNST) or the medial preoptic-anterior hypothalamic area (MPOAH). Comparison of intact and ST-lesioned brains revealed the existence of a ventral ...
