Malignant pheochromocytoma invading the ureteral wall muscle layer: A case report.

Pheochromocytoma is a neuroendocrine tumor for which surgical resection is the main treatment.Malignant pheochromocytoma is very rare. Here,we present a case of adrenal pheochromocytoma invading the ureteral wall muscle layer, which resulted in left adrenal and left nephrectomy.

The Chloroplast Protease AMOS1/EGY1 Affects Phosphate Homeostasis under Phosphate Stress.

Plastid intramembrane proteases in Arabidopsis (Arabidopsis thaliana) are involved in jasmonic acid biosynthesis, chloroplast development, and flower morphology. Here, we show that Ammonium-Overly-Sensitive1 (AMOS1), a member of the family of plastid intramembrane proteases, plays an important role in the maintenance of phosphate (P) homeostasis under P stress. Loss of function of AMOS1 revealed a striking resistance to P starvation.

[Study on Differential Optical Absorption Spectroscopy Data Processing Based on Chirp-Z Transformation].

Differential optical absorption spectroscopy (DOAS) is a commonly used atmospheric pollution monitoring method. Denoising of monitoring spectral data will improve the inversion accuracy. Fourier transform filtering method is effectively capable of filtering out the noise in the spectral data.
