Three-Dimensional Skin Tissue Printing with Human Skin Cell Lines and Mouse Skin-Derived Epidermal and Dermal Cells.

Since the skin covers most surfaces of the body, it is susceptible to damage, which can be fatal depending on the degree of injury to the skin because it defends against external attack and protects internal structures. Various types of artificial skin are being studied for transplantation to repair damaged skin, and recently, the production of replaceable skin using three-dimensional (3D) bioprinting technology has also been investigated. In this study, skin tissue was produced using a 3D bioprinter with human skin cell lines and cells extracted from mouse skin, and the printing conditions were optimized.

Percutaneous Vertebroplasty Using a Rotary Cutter for Treating Kümmell's Disease with Intravertebral Vacuum Cleft.

Background: Reported data indicate that the curative effect of percutaneous vertebroplasty (PVP) on the patients with intravertebral vacuum cleft (IVC) is worse than on those without IVC.

Objectives: This study was to prospectively investigate the advantage of rotary cutter-PVP (RC-PVP) in patients with Kümmell's disease with IVC.

Study Design: A prospective outcome study.

New prehospital scoring system for traumatic brain injury to predict mortality and severe disability using motor Glasgow Coma Scale, hypotension, and hypoxia: a nationwide observational study.

Objective: Assessing the severity of injury and predicting outcomes are essential in traumatic brain injury (TBI). However, the respiratory rate and Glasgow Coma Scale (GCS) of the Revised Trauma Score (RTS) are difficult to use in the prehospital setting. This investigation aimed to develop a new prehospital trauma score for TBI (NTS-TBI) to predict mortality and disability.

Effects of the Patient-Centered Environment Program on Behavioral and Emotional Problems in Home-Dwelling Patients With Dementia.

The current pilot study examined the effects of the Patient-Centered Environment Program (PCEP) on agitation, cognition, stress, pain, sleep, and activities of daily living for home-dwelling patients with dementia. Nine individuals participated in the study. The PCEP included visual, auditory, olfactory, and tactile areas based on participants' preferences.

Infratentorial and intraparenchymal subependymoma in the cerebellum: case report.

Subependymomas are rare benign tumors located in the ventricular system. Intraparenchymal subependymoma is extremely rare; only 6 cases have been reported, and all were located in the supratentorial region. We describe a case of infratentorial, intraparenchymal subependymoma in a 28-year-old man with intermittent headache.

Spinal cystic schwannoma: an MRI evaluation.

Spinal cystic schwannomas are a very rare entity and have been reported in only a few case reports in literature; its diagnosis and management has remained a challenge. This study reviewed the results of magnetic resonance imaging (MRI) of 12 patients (7 men and 5 women; aged 37 - 67 years; mean age: 52.75 years) with pathologically proven cystic schwannoma of the spine and discussed their differential diagnosis.

Modeling the diffusion of nitric oxide produced by neuronal cells in brain ischemia.

Mathematical models of NO diffusion were established to investigate the role of nitric oxide produced by neuronal cells in brain ischemia. Results showed that NO synthesized at early stage of brain ischemia could diffuse to a far more distant than that of a resting state. We speculate the roles of NO produced by neuronal cells in brain ischemia might have two different effects, depending on its concentration.
