Spin-Dependent First-Principles Study on Optoelectronic Properties of Neodymium Zirconates Pyrochlores NdZrO in Fd-3m and Pmma Phases.

Rare-earth zirconate pyrochlores (REZrO) are of much fundamental and technological interest as optoelectronic, scintillator and thermal barrier coating materials. For the first time, we report the detailed optoelectronic properties of rare-earth zirconates NdZrO in both, i.e.

Immuno-histological changes in lupus nephritis in female patients: a four-year study.

The objective of this study was to classify renal biopsies of all female patients diagnosed to have systemic lupus erythematosus at the College of Medicine, King Abdul Aziz University Hospital, Jeddah, Saudi Arabia over a period of four years between 19th January 2002 and 30th April 2006. Lupus nephritis was classified according to the modified WHO classification. The immunofluorescence pattern was also studied.

Lupus nephritis. Clinicopathological correlation.

Objective: To classify all renal biopsies of lupus nephritis patients presenting in the last 10 years, according to the modified World Health Organization (WHO) classification using the facilities of light, fluorescent, and electron microscopy. To assess the activity and chronicity indices of renal biopsies according to the National Institute of Health protocol, and to correlate the histological findings with the clinical features of the patients presented up to the time of biopsy.

Methods: Seventy-eight patients with lupus nephritis, biopsied over 10 years between January 1995 to December 2005 in King Abdul-Aziz University Hospital, Jeddah, Kingdom of Saudi Arabia were reviewed by 2 histopathologists with the assistance of a nephrologist.

Urinary Bladder Botryoid Rhabdomyosarcoma with Immature Cartilage in a 24-year-old Male Patient: A Case Report.

We report a case of botryoid rhabdomyosarcoma with cartilaginous differentiation in the urinary bladder of a 24-year-old male. The tumor possessed the diagnostic histologic and immuno-histochemical characteristics of botryoid rhabdomyosarcoma. Foci of immature cartilage were noted within the tumor.
