The pathological result of torsional testis.

<p>6A-6B: the orchiectomy specimens showed that the size of torsional testis increased and the testis infarction appeared dark red or jet black; 6C-6E: HE staining showed that the lobular gap cavities of infarct testis was filled with diffuse hemorrhage and sporadic died interstitial cells, a large number of spermatogonia, extensive coagulation necrosis of spermatocytes in seminiferous tubules, interstitial hyperplasia and lymphocyte infiltration.</p

Strain Control of Giant Magnetic Anisotropy in Metallic Perovskite SrCoO_3−δ Thin Films

Magnetic materials with large magnetic anisotropy are essential for workaday applications such as permanent magnets and magnetic data storage. There is widespread interest in finding efficient ways of controlling magnetic anisotropy, among which strain control has proven to be a very powerful technique. Here, we demonstrate the strain-mediated magnetic anisotropy in SrCoO_3−δ thin film, a perovskite oxide that is metallic and adopts a cubic structure at δ ≤ 0.25. We find that the easy-magnetization axis in SrCoO_3−δ can be rotated by 90° upon application of moderate epitaxial strains ranging from −1.2 to +1.8%. The magnetic anisotropy in compressive SrCoO_3−δ thin films is huge, as shown by magnetic hysteresis loops rendering an anisotropy energy density of ∼10⁶ erg/cm³. The local variance in magnetic force microscopy upon temperature and magnetic field reveals that the evolution of magnetic domains in the SCO thin film is strongly dependent on magnetic anisotropy
