Characterization of Mechanical Properties and Grain Size of Stainless Steel 316L via Metal Powder Injection Molding.

The metal powder injection molding process is completed by mixing a metal powder and a binder, performing an injection molding and degreasing process, and then performing a sintering process for high density. The disadvantage of metal powder injection molding is that defects occurring during the process affect mechanical properties, which are worse in mechanical properties than in products manufactured by cold-rolling. In this study, the mechanical properties and microstructure of stainless steel 316L manufactured by the metal powder injection molding process were analyzed.

Simultaneous bilateral stenosis of the vertebral arteries treated by unilateral decompression: a case report.

A 56-year-old man presented with a 3-month history of progressive dizziness. His dizziness was aggravated when his head was rotated to the right side. Diagnostic angiography showed that a normal right-sided vertebral artery in the neutral position became an abnormal vertebral artery with two stenotic lesions at the C3-4 and C5-6 levels when the patient's head was turned to the right.

Distribution of viral RNA in mouse tissues during acute phase of coxsackievirus B5 infection.

Objective: To investigate histopathological changes and distribution of coxsackievirus B5 (CVB5) RNA in mouse heart, liver, and pancreas during the acute phase of infection.

Methods: C3H/HeJ male mice, aged 3-4 weeks, were inoculated intraperitoneally with 5 x 10(5) plaque-forming units of CVB5 and sacrificed at 1, 2, 3, 4, 7 and 10 days postinfection (p.i.
