Optical and electrical properties of all-inorganic CsAgBiBr double perovskite single crystals.

In this work, we explored the possibility of using CsAgBiBr, a double perovskite crystal, for radiation detection. CsAgBiBr crystals were grown using the solution growth technique. The resistivity of the as-grown CsAgBiBr crystal is larger than 10 Ω cm, which is high enough to ensure low leakage current for fabrication of semiconductor radiation detectors.

Etiologic revelation and outcome of the surgical management of idiopathic granulomatous mastitis; An Egyptian centre experience.

Introduction: Idiopathic granulomatous mastitis (IGM) is a chronic inflammatory condition that is confused with cancer. It usually affects women in child bearing age. The exact aetiology and pathogenesis are still unknown, and the optimal therapeutic modality has not yet been established.

[Macular edema caused by contraction of the posterior hyaloid in diabetic retinopathy. Surgical treatment of a series of 22 cases].

We have observed some patients with diabetic macular edema who did not respond to grid laser treatment and who improved with spontaneous posterior vitreous detachment or vitrectomy. These cases have a taut and glistening vitreo-macular interface. Three such cases are presented in detail.

[Mixed photoreceptor dystrophy. Apropos of two cases].

Two observations of cone-rod dystrophy are reported. It's about two brothers. The transmission way is not defined.
