Comparative Study
Comparison of mesenchymal stem cell sheets and chondrocyte sheets in a rabbit growth plate injury model.
The treatment of posttraumatic deformities and differences in length between the extremities resulting from physeal injury remains controversial. The aims of this study were to compare the efficacy of tissue-engineered, monolayer, and allogeneic mesenchymal stem cell sheets and chondrocyte sheets for physeal arrest treatment and to investigate cell sheet technology as a novel method for cell transplantation in physeal cartilage repair. ⋯ Our results support the hypothesis that MSC or chondrocyte transplantation using the cell-sheet technique described in the present study aids in the regeneration of cartilage tissue during physeal arrest after growth plate damage.

To investigate the correlation between the Glasgow-Blatchford score, shock index, and Forrest classification in patients with peptic ulcer bleeding (PUB). ⋯ A moderate correlation was observed between the Glasgow-Blatchford score and shock index in patients with PUB, and the correlation between the Forrest classification and Glasgow-Blatchford score or shock index was relatively low.

Comparative Study
Real-Life Comparison of the Viewing Angle and the Image Quality of Two Commonly Used Viewing Systems for Vitreoretinal Surgery.
To compare the clinical use, image quality and viewing angle of a commonly used contact wide angle viewing (WAV) system (Advanced Visual Instruments (AVI) Panoramic Imaging Systems, NY, USA) with a commonly used noncontact WAV system (Leica RUV800, Leica Microsystems, Switzerland). ⋯ Both WAV systems provided high image quality and adequate viewing angles in most cases. However, the contact system appeared to provide a superior image quality and/or a wider viewing angle in more challenging situations. The difficulty of holding the contact lens in place was found to be moderate.

Gastrointestinal (GI) cancers are among the most common cancers in the world. Many risk factors may increase the chance of developing GI cancers. In recent years, a number of epidemiological studies have reported evidence of carcinogenic effects of opium in humans. This study aimed to investigate the relationship between opium use and GI cancer. ⋯ Opium, in the form used among drug users in this area, can lead to an increased risk of GI cancers. Fruit and vegetables have a protective and modifying effect on the risk of GI cancer development caused by opium consumption.

The aim of this study was to investigate the possible toxicity of the Ankaferd Blood Stopper (ABS) on the neural system. ⋯ No clinical or histopathological evidence for the neurotoxic effect of the ABS was observed in the present study. Our findings might precipitate the use of ABS on human subjects regarding medulla spinalis surgery.
