Significance of central noradrenergic system on harmaline induced tremor [PDF]

open access: yesPharmacology Biochemistry and Behavior, 1979
Since there is degeneration of substantia nigra concomitant with that of locus coeruleus (LC) in patients with Parkinson's disease, the study was performed to determine the role of central norepinephrine (NE) on harmaline induced tremor. The duration of harmaline (10 mg/kg IP) induced tremor was significantly reduced by intraventricular administration ...

TCMD: A High‐Throughput and Rapid Method for Screening Antimicrobial Ingredients from Renewable Bio‐Based Resources

open access: yesAdvanced Science, Volume 12, Issue 27, July 17, 2025.
This study develops a strategy to screen the active compounds from bio‐mixtures via combining transcriptomic profiling and molecular docking. The proposed method demonstrates 100% correction in three different biobased mixtures and is 3–20 times faster than traditional approaches.
