Red-shifted GRAB acetylcholine sensors for multiplex imaging .

The neurotransmitter acetylcholine (ACh) is essential in both the central and peripheral nervous systems. Recent studies highlight the significance of interactions between ACh and various neuromodulators in regulating complex behaviors. The ability to simultaneously image ACh and other neuromodulators can provide valuable information regarding the mechanisms underlying these behaviors.

multiplex imaging of dynamic neurochemical networks with designed far-red dopamine sensors.

Neurochemical signals like dopamine (DA) play a crucial role in a variety of brain functions through intricate interactions with other neuromodulators and intracellular signaling pathways. However, studying these complex networks has been hindered by the challenge of detecting multiple neurochemicals simultaneously. To overcome this limitation, we developed a single-protein chemigenetic DA sensor, HaloDA1.

Semantic segmentation for weed detection in corn.

Background: Reliable, fast, and accurate weed detection in farmland is crucial for precision weed management but remains challenging due to the diverse weed species present across different fields. While deep learning models for direct weed detection have been developed in previous studies, creating a training dataset that encompasses all possible weed species, ecotypes, and growth stages is practically unfeasible. This study proposes a novel approach to detect weeds by integrating semantic segmentation with image processing.

Lipid composition and grafted PEG affect in vivo activity of liposomal mitoxantrone.

Mitoxantrone was encapsulated into pegylated SUVs using ammonium sulfate gradient method. Four formulations (LM-s, LM-p, LM-m and LM-m-L) were prepared, which were made from different PCs and exhibited different PEG grafting density. In vitro release studies revealed that drug release rate increased with decreased T(m) of PCs, and reduced PEG polymer coverage.

Encapsulation of mitoxantrone into pegylated SUVs enhances its antineoplastic efficacy.

Mitoxantrone (MIT) was encapsulated into 60, 80 and 100nm pegylated hydrogenated soy phosphatidylcholine/cholesterol (HSPC/chol) vesicles using a transmembrane (NH(4))(2)SO(4) gradient. In-vitro release studies revealed that small-sized formulation had fast drug-release rate. Acute toxicity studies performed in c57 mice proved that all pegylated liposomal MIT (plm) formulations could be well-tolerated at a dose of 9mg/kg, significantly compared to severe toxicity induced by free mitoxantrone (f-M).
