N-acetylcysteine mitigates oxidative damage to the ovary in D-galactose-induced ovarian failure in rabbits.

Background: Oxidative damage to the ovaries is the primary cause of impaired reproductive functions in female animals. This study aimed to investigate the protective role of N-Acetyl-L-cysteine (NAC) in reducing oxidative damage in the ovaries of female rabbits.

Methods And Results: Female rabbit ovaries were treated in vitro with varying concentrations of D-galactose (D-gal): 0, 5, 10, and 15 mg/mL, and it was found that 10 mg/mL D-gal significantly disrupted follicular structures, causing disarray in granulosa cell arrangements and significantly reducing T-SOD and GSH levels (p < 0.

A Photolysis-Assist Molecular Communication for Tumor Biosensing.

Molecular communication (MC) is a promising bioinspired paradigm for exchanging molecule information among nanomachines. In this paper, we propose a synchronization-assist photolysis MC system that aims to transmit the biosensing signal of the tumor microenvironment, facilitated by mitigating redundant molecules for improved bit error rate (BER) performance. Benefits from biocompatible MC, biosensors could transmit biosensing signals of the tumor in vivo instead of converting them to electrical signals.

Bioinspired Ferroelectric Polymer Arrays as Photodetectors with Signal Transmissible to Neuron Cells.

A bioinspired photodetector with signal transmissible to neuron cells is fabricated. Photoisomerization of the dye molecules embedded in the ferroelectric polymer membrane achieves electric polarization change under visible light. The photodetector realizes high sensitivity, color recognition, transient response, and 3D visual detection with resolution of 25 000 PPI, and, impressively, directly transduces the signal to neuron cells.
