A case of an extruded cervical intervertebral disc at C7-D1 level with intradiscal hematoma in a 68-year-old male patient is presented. MR imaging showed a posterolateral extradural hemorrhagic lesion at C7-D1 level. It was suggestive of an epidural hematoma or a bleed within a neoplasm. A posterior approach was adopted and an extruded intervertebral disc with intradiscal hematoma was found and...

In the present study, 1.1 volume percent of nano size copper was incorporated into pure tin using hybrid microwave sintering assisted powder metallurgy route. Microwave sintered samples were extruded both at room temperature and at 230 °C. Microstructural characterization studies were conducted on the extruded samples to investigate the distribution characteristics of secondary phase and grain ...

Smooth polystyrene (PS) and polyamide 12 (PA 12) surfaces were produced via an injection molding process followed by a smoothing subsequently treated with O2 plasma to increase the number of polar groups capable hydrogen bond formation on surface. The presence related was evident from X-ray photoelectron spectroscopy (XPS) contact angle measurements. sample topographies investigated atomic forc...

BACKGROUND Endodontic instrumentation carries the risk of over extrusion of debris and bacteria. The technique used and the type of instrumentation influences this risk. AIM The purpose of this study was to evaluate and compare the K-file, ProTaper hand and ProTaper rotary instrumentation systems for the amount of apically extruded debris, irrigant solution and intracanal bacteria. DESIGN E...

Mixtures of cereals and legumes result in products with higher content of high biological value proteins. The thermoplastic extrusion promotes the transformation of chemical, physical and nutritional characteristics of the food such as starch gelatinization and promotes the inactivation of anti-nutritional compounds and enzymes. This study aimed to develop products extruded using broken rice an...

Extrusion is one of the widest used and the most basic processes of plastic forming, and the metal flow in extrusion is affected by many factors, such as friction, die shape, billet temperature and so on. Among these factors, friction is the key boundary condition to determine the property of the extruded products. In this paper research and measurements of velocity fields and impact of frictio...

A comparative study of extruded and ground maize meals as raw materials for the production of regular (12°P) and high gravity (20°P) worts was devised. Extruded water solubility index (WSI) was higher (9.8 percentage units) and crude fat was lower (2.64 percentage units) compared to ground maize. Free-amino nitrogen compounds (FAN), pH, and glucose were evaluated in regular and high gravity wor...

We conducted two trials to evaluate the effects of extruding vs dry-rolling either corn or grain sorghum on intake, digestibility, and performance of finishing steers. In Trial 1, 92 crossbred steers (average BW 413 kg) were used in a 2 x 2 factorial design. Diets contained either dry-rolled corn (RC), extruded corn (EC), dry-rolled grain sorghum (RGS), or extruded grain sorghum (EGS). Diets we...

A completely extruded talus without any remaining soft tissue attachments is extremely rare. The present report describes treatment of a 45-year-old man who sustained a completely extruded talus injury following a rock-climbing fall. Upon admission, the extruded talus was deep-frozen in our bone bank. The open ankle joint underwent massive wound debridement and irrigation for 3 days. Four days ...
