The applicability of a deep learning model for the virtual staining of plant cell structures using bright-field microscopy was investigated. The training dataset consisted of microscopy images of tobacco BY-2 cells with the plasma membrane stained with the fluorescent dye PlasMem Bright Green and the cell nucleus labeled with Histone-red fluorescent protein. The trained models successfully detected the expansion of cell nuclei upon aphidicolin treatment and a decrease in the cell aspect ratio upon propyzamide treatment, demonstrating its utility in cell morphometry.

This study aimed to synthesize MgFeLnO (where, Ln = Yb, Pr, Gd, and Nd) ferrite nanoparticles via the sol-gel process and investigate their structural, morphological, and magnetic properties for potential hyperthermia applications. X-ray diffraction analysis (XRD) confirmed the cubic spinel structure for all samples. Transmission electron microscopy (TEM) images revealed nanometer-scale dimensions and nearly spherical morphology.

This study presents an efficient and interpretable framework for unsupervised detection of low, very low, and extreme birth weights. While traditional approaches to managing class imbalance require labeled data, our study explores the use of unsupervised learning to detect anomalies indicative of low birth weight scenarios.

Medications known as 'cognitive enhancers' are increasingly being consumed off-label by healthy people, raising concerns about their safety. The aim of our study was to profile behavioral performance upon oral administration of methylphenidate (2.5 mg/kg) and modafinil (64 mg/kg) - two popular cognitive enhancers - and upon their discontinuation.

Methods based on enzyme labelling strategies have been widely developed for capacitance immunoassays, but most suffer from low sensitivity and are unfavorable for routine use in the early stages of diagnostics. Herein, we designed a highly efficient capacitance immunosensing method for the low-abundance neuroblastoma biomarker neuron-specific enolase (NSE) using an interdigitated micro-comb electrode. Initially, monoclonal mouse anti-human NSE capture antibodies were immobilized on the interdigitated gold electrodes using bovine serum albumin.
