Evaluation of Dihedral Angle Twin Boundaries in Cu10 wt%Zn Alloy Using Atomic Force Microscopy.

Atomic force microscopy (AFM) measurements of dihedral angles are conducted for the first time to characterize the ratio of the twin-boundary energy (γΤ) to the surface free energy (γS). In plane, twin morphology is measured with AFM, verified by scanning electron microscopy, optical microscopy, and found to be consistent. The chemical composition and homogeneity of annealed Cu10 wt%Zn sample are confirmed by energy-dispersive spectroscopy.

Dendritic cell-based vaccines in treating recurrent herpes labialis: Results of pilot clinical study.

Recurrent herpes simplex labialis caused predominantly with herpes simplexvirus 1(HSV-1) is a major problem, for which various treatments have minimal impact. Given the important role of the immune system in controlling virus infection, an activation of virus-specific immune responses, in particular,using dendritic cell (DCs) vaccines, seems to be a promising approach for the treatment of patients with frequent recurrences of herpes labialis. The current paper presents the results of a pilot study of the safety and efficacy of DC vaccines in 14 patients with recurrent HSV-1 infections.

Safety and Therapeutic Potential of M2 Macrophages in Stroke Treatment.

Our objective was to evaluate the safety and clinical efficacy of autologous M2 macrophage transplantation in nonacute stroke patients. We also evaluated whether the intrathecal administration of macrophages influences the production of cytokines by peripheral blood cells and whether the levels of cytokines correlate with stroke severity and responsiveness to cell therapy. In this study, 13 patients (12 males and 1 female with a median age of 63 years) diagnosed with ischemic (n = 10) or hemorrhagic (n = 3) stroke were subjected to cell transplantation therapy (study group).

Spleen-preserving distal pancreatectomy with resection of the splenic vessels. Should one rely on the short gastric arteries?

Context: Knowing the collaterals is essential for a spleen-preserving distal pancreatectomy with resection of the splenic vessels.

Objective: To ascertain the sources of the blood supply to the spleen after a spleen-preserving distal pancreatectomy with resection of the splenic vessels.

Methods: Perfusion of the cadaveric left gastric and right gastroepiploic arteries with methylene blue after occlusion of all the arteries except the short gastric arteries (n=10).
