Adrenal oncocytoma: a rare presentation of a benign 18F-fluorodeoxyglucose PET avid virilising adrenal tumour.

A woman in her 70s presented with features of hyperandrogenism including clitoral enlargement and deepening of her voice. Biochemical investigations revealed raised plasma androgens and urinary androgen metabolites and imaging findings showed a highly F-18 fluorodeoxyglucose (FDG)-PET avid left adrenal tumour initially suspected to be a malignant adrenocortical carcinoma (ACC). She subsequently underwent an uncomplicated laparoscopic adrenalectomy where complete resection of her tumour was achieved.

Simultaneous prediction of the API concentration and mass gain of film coated tablets using Near-Infrared and Raman spectroscopy and data fusion.

This study investigates the simultaneous prediction of active pharmaceutical ingredient (API) concentration and mass gain in film-coated tablets using Partial Least Squares (PLS) regression combined with three data fusion (DF) techniques: Low-Level (LLDF), Mid-Level (MLDF), and High-Level (HLDF). Near-Infrared (NIR) and Raman spectroscopy were utilized in both reflection and transmission modes, providing four types of spectral data per tablet. Transmission models proved more effective for API prediction by capturing data from the entire tablet, while reflection models excelled in assessing mass gain by focusing on the surface layer.
