Nuclear imaging in Parkinson's disease: The past, the present, and the future.

The current review analyzed Parkinson's disease-related (PD) literature published from 1817 to 2021 and specifically concentrated on imaging-related works published from the 1960s to 2021. We analyzed the history of PD-related imaging development, its current condition, and pointed out some understudied aspects to be investigated in the future. The present review is specifically concentrated on nuclear imaging techniques.

Enhancing capacity and synthesis of [68Ga]68-Ga-PSMA-HBED-CC with the lyophilized ready-to-use kit for nuclear pharmacy applications.

Introduction: The authors describe the newly proposed synthesis technique for the gallium-68 (Ga-68)-labeled tracer ([Ga]Ga-PSMA-HBED-CC) for imaging expression of the prostate-specific membrane antigen (PSMA). An effort was applied to design the lyophilized cold kit (isoPROtrace-11) as a time-saving technique resulting in increased radiochemical yields.

Procedures: The initial material for labeling was obtained from a Ge/Ga-generator.

Genetic screen of the yeast environmental stress response dynamics uncovers distinct regulatory phases.

Cells respond to environmental fluctuations by regulating multiple transcriptional programs. This response can be studied by measuring the effect of environmental changes on the transcriptome or the proteome of the cell at the end of the response. However, the dynamics of the response reflect the working of the regulatory mechanisms in action.

Semiautomated synthesis of a novel [18F] amine fluorocyanoborane for PET imaging studies. Radiosynthesis and in vivo characterization in rats.

A novel fluorine-18 labeled amine fluorocyanoborane derivative was synthesized from the bromo-derivative precursor in 22% radiochemical yield. The [18F] labeling was accomplished by a semiautomatic method that is based on the synthesis of Ag 18F from Ag2CO3 and H 18F in a platinum dish followed by sonication of the bromo-precursor with Ag 18F in dry benzene to produce [18F] labeled amine fluorocyanoborane which was used with no further purification. A total of 50 microCi of the [18F] labeled amine fluorocyanoborane was injected into normal, female Sprague-Dawley rats (250-300 g) via the tail vein and monitored by Positron emission tomography (PET)/CT to detect its biodistribution in the rat body.

Synthesis and antifungal activity of a novel series of alkyldimethylamine cyanoboranes and their derivatives.

A series of new amine cyanoborane derivatives were synthesized and exhibited antifungal activity. A long alkyl chain attached to the nitrogen of the amine cyanoboranes and carboxyboranes enhances antifungal activity. An enhanced activity was also obtained upon the halogenation of the amine cyanoboranes as well as in the presence of C=C double bond at the end of the N-alkyl group.
