Impact of maternal energy drink consumption during gestation and lactation on brain health in neonatal Wistar albino rats
Abstract Energy drinks are rapidly gaining prominence in the global beverage industry, with projected sales reaching $60 billion within the next five years. These beverages often contain high levels of caffeine and the amino acid taurine, among other ingredients. The increasing consumption of energy drinks by children has sparked concerns regarding potential caffeine toxicity. In the present study, an energy drink was administrated at doses of 5 ml/Kg or 10 ml/Kg body weight. The comet assay demonstrated a significant elevation in DNA damage, evidenced by increased % DNA in tail and olive tail moment in the energy drink groups. Additionally, there were notable elevation in malondialdehyde levels as an oxidative stress marker, while reduction in superoxide dismutase activity and glutathione levels as antioxidant markers in energy drink groups. Furthermore, acetylcholinesterase activity and dopamine levels were significantly decrease in the energy drink groups compared to the control group. The high-dose groups exhibited a more pronounced effect than the low-dose groups, indicating a dose-dependent adverse effect.

Pulse sequence design for high field NMR with NV centers in dipolarly coupled samples
Abstract Diamond-based quantum sensors have enabled high-resolution NMR spectroscopy at the microscale in scenarios where fast molecular motion averages out dipolar interactions among target nuclei. However, in samples with low-diffusion, ubiquitous dipolar couplings challenge the extraction of relevant spectroscopic information. In this work we present a protocol that enables the scanning of nuclear spins in dipolarly-coupled samples at high magnetic fields with a sensor based on nitrogen vacancy (NV) ensembles. Our protocol is based on the synchronized delivery of radio frequency (RF) and microwave (MW) radiation to eliminate couplings among nuclei in the scanned sample and to efficiently extract target energy-shifts from the sample’s magnetization dynamics. In addition, the method is designed to operate at high magnetic fields leading to a larger sample thermal polarization, thus to an increased NMR signal. The precision of our method is ultimately limited by the coherence time of the sample, allowing for accurate identification of relevant energy shifts in solid-state systems.
