[Anti-breast cancer effect of a mitochondrion-targeted derivative of ergosterol peroxide in vitro and in vivo].

This study aims to explore the effect and mechanism of a mitochondrion-targeted derivative of ergosterol peroxide(Mito-EP) on breast cancer. The methyl thiazolyl tetrazolium(MTT) assay was employed to examine the proliferation of MDA-MB-231 cells treated with different concentrations(0, 0.075, 0.

Comparison of DNA-Gold Nanoparticle Conjugation Methods: Application in Lateral Flow Nucleic Acid Biosensors.

Lateral flow nucleic acid biosensors (LFNABs) have attracted extensive attention due to their rapid turnaround time, low cost, and results that are visible to the naked eye. One of the key steps to develop LFNABs is to prepare DNA-gold nanoparticle (DNA-AuNP) conjugates, which affect the sensitivity of LFNABs significantly. To date, various conjugation methods-including the salt-aging method, microwave-assisted dry heating method, freeze-thaw method, low-pH method, and butanol dehydration method-have been reported to prepare DNA-AuNP conjugates.

Disease Quantification of Liver Lymphoma in CT Images without Lesion Segmentation.

Aim: This study aimed to automatically implement liver disease quantification (DQ) in lymphoma using CT images without lesion segmentation.

Background: Computed Tomography (CT) imaging manifestations of liver lymphoma include diffuse infiltration, blurred boundaries, vascular drift signs, and multiple lesions, making liver lymphoma segmentation extremely challenging.

Methods: The method includes two steps: liver recognition and liver disease quantification.
