Article Synopsis
  • This study investigates the safety and effectiveness of using umbilical cord-derived stem cells to help repair heart function in patients who experienced acute STEMI and had reduced left ventricular ejection fraction (LVEF) after revascularization.
  • Eight patients participated, with six completing the study, and there were no serious adverse events reported during the treatment or follow-up.
  • Results showed significant improvements in heart function, including increased LVEF and decreased NT-proBNP levels, suggesting the therapy could be promising, but further research is needed.

Article Synopsis
  • - Recent trends show a surge in popularity for oxygenated water brands claiming health benefits, particularly for athletes aiming to enhance performance by improving oxygen levels in the body.
  • - A study aimed to investigate the effects of oxygenated water on uric acid metabolism in rats, using NMR spectroscopy to characterize the water and measure serum uric acid levels after inducing hyperuricemia with oxonic acid.
  • - Results indicated that rats drinking oxygenated water experienced lower serum uric acid levels and improved uric acid metabolism compared to those drinking regular water, suggesting that oxygenated water could be an effective supportive therapy for hyperuricemia.

Dental caries (tooth decay) is the most frequent oral disease in humans. Filling cavities with a dental restorative material is the most common treatment, and glass ionomer cements are the main fluoride ion release restorative materials. The goal of this study was to develop a restorative compound with superior fluoride ion release and recharge abilities.

Background/purpose: Spinal cord injury (SCI) is a devastating medical condition for which no effective pharmacological interventions exist. l-Theanine (LT), a major amino acid component of green tea, exhibits potent antioxidative and anti-inflammatory activities and protects against various neural injuries. Here, we evaluated the potential therapeutic effects of LT on the recovery of behavioral motor functions after SCI in rats and the underlying neuroprotective mechanisms.

Rotenone (ROT)-induced neurotoxicity has been used for decades as an animal model of Parkinson's disease (PD) in humans. This model exhibits pathophysiological features similar to those reported in patients with PD, namely, striatal nitrosative and oxidative stress, mitochondrial dysfunction, and neural cytoarchitecture alteration. (-)Epigallocatechin-3-gallate (EGCG), the most abundant and potent green tea catechin, has notable anti-oxidative, anti-inflammatory, and neuroprotective effects.

Molar pits and fissures tend to be affected by caries due to cleaning difficulties. As such, the filling of pits and cracks with sealants is common to deter the onset of caries. However, current clinical practices rely on sealants that lack the ability to release and recharge fluoride ions.

Traditional photodynamic therapy (PDT) is limited by the penetration depth of visible light. Although the light source has been changed to near infrared, infrared light is unable to overcome the penetration barrier and it is only effective at the surface of the tumors. In this study, we used X-ray as a light source for deep-seated tumor treatment.

HepG2 cell death with magnetic hyperthermia (MHT) using hydroxyapatite nanoparticles (mHAPs) and alternating magnetic fields (AMF) was investigated in vitro. The mHAPs were synthesized as thermo-seeds by co-precipitation with the addition of Fe. The grain size of the HAPs and iron oxide magnetic were 39.

Unlabelled: Recently, photodynamic therapy (PDT) is one of the new clinical options by generating cytotoxic reactive oxygen species (ROS) to kill cancer cells. However, the optical approach of PDT is limited by tissue penetration depth of visible light. In this study, we propose that a ROS-enhanced nanoparticle, hafnium-doped hydroxyapatite (Hf:HAp), which is a material to yield large quantities of ROS inside the cells when the nanoparticles are bombarded with high penetrating power of ionizing radiation.
