AI Article Synopsis

  • Polydatin, derived from the herb Polygonum cuspidatum, was studied for its potential protective effects against learning and memory issues caused by hypoxic-ischemic brain injury (HIBI) in neonatal rats.
  • The study found that neonatal rats with induced HIBI exhibited memory deficits, but those treated with polydatin showed improved long-term learning and memory abilities.
  • It was also discovered that polydatin increases the expression of brain-derived neurotrophic factor (BDNF) in the hippocampus, suggesting that its protective effects against brain tissue injury and memory impairment may involve the enhancement of BDNF levels.

Article Abstract

Polydatin is a key component of Polygonum cuspidatum, a herb with medical and nutritional value. The present study investigated the protective effect of polydatin against learning and memory impairment in neonatal rats with hypoxic‑ischemic brain injury (HIBI). The unilateral common carotid artery ligation method was used to generate neonatal HIBI rats. Y‑maze testing revealed that rats with HIBI exhibited memory impairment, while rats with HIBI treated with polydatin displayed enhanced long‑term learning and memory. Of note, polydatin was found to upregulate the expression of hippocampal brain‑derived neurotrophic factor (BDNF) in rats with HIBI. BDNF has a role in protecting HIBI‑induced brain tissue injury and alleviating memory impairment. These findings showed that polydatin had a protective effect against learning and memory impairment in neonatal rats with HIBI and that the protective effect may be mediated through the upregulation of BDNF.

Medical volume data are rapidly increasing, growing from gigabytes to petabytes, which presents significant challenges in organisation, storage, transmission, manipulation, and rendering. To address the challenges, we propose an end-to-end architecture for data compression, leveraging advanced deep learning technologies. This architecture consists of three key modules: downsampling, implicit neural representation (INR), and super-resolution (SR).

Koopman operator theory has found significant success in learning models of complex, real-world dynamical systems, enabling prediction and control. The greater interpretability and lower computational costs of these models, compared to traditional machine learning methodologies, make Koopman learning an especially appealing approach. Despite this, little work has been performed on endowing Koopman learning with the ability to leverage its own failures.

In the present study, the effects of the acetylcholinesterase (AChE) enzyme inhibitor rivastigmine (RIVA) on spike-wave discharges (SWDs), memory impairment, anxiety-like behavior, and the transient receptor potential vanilloid 1 (TRPV1) gene expression were investigated in genetic absence epileptic Wistar Albino Glaxo/Rijswijk (WAG/Rij) rats. After tripolar electrodes were implanted on the WAG/Rij rats' skulls, single doses of 0.125, 0.

Background: Our previous studies reported that D-galactose (D-gal) administration for four to eight weeks caused metabolic disturbance, brain mitochondrial dysfunction, and brain aging, leading to cognitive dysfunction in similar with natural aging condition. Spermidine is a polyamine that can be found naturally. Spermidine has been showed the beneficial effects on various models, such as attenuating metabolic/gut impairments in obesity, and ameliorating memory loss in aged model.

Background: Alzheimer's disease (AD) is the most common tauopathy and characterized by the progressive accumulation of Aß and tau. Tau is expressed in two major isoforms containing either 3 or 4 c-terminal repeats labeled as 3R and 4R tau. While these two isoforms occur in roughly equimolar ratios in AD, most research focus and mouse models of tau center only the 4Rtau protein and not 3Rtau.
