This study addresses the thermal management challenge in battery systems by enhancing phase change material composites with Ni-P and Ni-P-Cu coatings on phase change material/expanded graphite structures. Traditional phase change materials are limited by low thermal conductivity and mechanical stability, which restricts their effectiveness in high-demand applications. Unlike previous studies, this work integrates Ni-P and Ni-P-Cu coatings to significantly improve both the thermal conductivity and mechanical strength of phase change material/expanded graphite composites, filling a crucial gap in battery thermal management solutions.

This study evaluates the protective effects of sinapic acid (SA), a polyphenolic compound with diverse biological activities, against ethanol-induced gastric ulcers in rats. A gastric ulcer model was established using ethanol (ETH), and the experimental groups received either omeprazole (OMEP, 20 mg/kg) or SA at doses of 20 mg/kg and 40 mg/kg via oral gavage for 14 days. Biochemical markers, including total antioxidant status (TAS), total oxidant status (TOS), oxidative stress index (OSI), malondialdehyde (MDA), and myeloperoxidase (MPO) activity, were assessed alongside proinflammatory cytokines (tumor necrosis factor-alpha (TNF-α), interleukin-1 beta (IL-1β), and IL-6) using ELISA.

Article Synopsis
  • The study investigates the relationship between language impairments and central auditory processing difficulties in children with self-limited epilepsy characterized by centrotemporal spikes, examining how these issues relate to seizure timing and neuropsychiatric aspects.
  • Two groups of patients based on seizure timing underwent various assessments, revealing that both groups performed significantly worse on auditory processing tests compared to healthy controls, with some differences in expressive language scores.
  • Findings indicate that children experiencing seizures at night may show more behavioral issues and impulsivity compared to those with seizures in the morning, highlighting the complex interactions between epilepsy, language, and neuropsychiatric functioning.

Article Synopsis
  • The study compares macular vessel density (VD) in patients with macula-off rhegmatogenous retinal detachment (RRD) who underwent vitrectomy using either gas or silicone oil (SO) tamponade.
  • Fifty patients participated, and results showed that both groups had significant improvements in best-corrected visual acuity (BCVA) after surgery, but the gas tamponade group had better outcomes.
  • The silicone oil group had lower VD in certain retinal layers, indicating possible toxic effects on macular perfusion, while gas tamponade appeared to preserve VD, suggesting a preference for gas tamponade in these cases.

Liraglutide and other glucagon-like peptide 1 receptor agonists (GLP-1RAs) are effective weight loss drugs, but how they suppress appetite remains unclear. One potential mechanism is by activating neurons that inhibit the hunger-promoting Agouti-related peptide (AgRP) neurons of the arcuate hypothalamus (Arc). To identify these afferents, we developed a method combining rabies-based connectomics with single-nucleus transcriptomics.

  • This study explored the use of diffusion-weighted MRI to evaluate prostate cancer patients with Gleason score 7 tumors before radiotherapy, focusing on the correlation between MRI results, cancer characteristics, and treatment outcomes.
  • It was found that tumors classified as GS 3+4 had higher ADC values compared to GS 4+3 tumors, indicating a difference in disease aggression, with lower ADC values linked to poorer survival rates.
  • The research concluded that ADC values could serve as an effective biomarker to distinguish between different types of GS 7 tumors, with lower values correlating with a higher risk of disease progression and worse long-term outcomes.

The first search for soft unclustered energy patterns (SUEPs) is performed using an integrated luminosity of 138  fb^{-1} of proton-proton collision data at sqrt[s]=13  TeV, collected in 2016-2018 by the CMS detector at the LHC. Such SUEPs are predicted by hidden valley models with a new, confining force with a large 't Hooft coupling. In events with boosted topologies, selected by high-threshold hadronic triggers, the multiplicity and sphericity of clustered tracks are used to reject the background from standard model quantum chromodynamics.
