This study presents the development of biocompatible and biodegradable nanocomposites utilizing renewable cellulose nanocrystals (CNCs) in polycaprolactone (PCL)-based polyurethane acrylates (PUA) through in situ polymerization. First, CNCs were derived from cotton linter via acid hydrolysis; then functionalized with 3-methacryloxypropyltrimethoxysilane to produce silane-modified CNCs (S-CNCs). CNCs offered uniform dispersion in PUA up to 2 wt% loading, resulting in significant property enhancements, including ∼60 % increase in tensile strength and ∼25 % increase in Young's modulus.

Article Synopsis
  • * Researchers used three behavioral tasks (Morris water maze, Passive avoidance, and T-maze place preference) to assess the importance of these hippocampal regions for each task and confirmed the tasks' sensitivity through lidocaine injections.
  • * Findings indicate that silencing astrocytes with fluorocitrate in the dorsal hippocampus impair performance in certain tasks, while the intermediate and ventral regions show variable effects, suggesting astrocytes have specific roles in memory related to aversive and rewarding experiences in the hippoc

Background: Glioblastoma multiforme (GBM) is the most malignant brain tumor, with a poor prognosis and life expectancy of 14-16 months after diagnosis. The standard treatment for GBM consists of surgery, radiotherapy, and chemotherapy with temozolomide. Most patients become resistant to treatment after some time, and the tumor recurs.

Purpose: To evaluate the effect of early posttrabeculectomy bleb leakage on trabeculectomy surgery outcomes and success rate.

Methods: The present prospective cohort study was conducted on 203 eyes of 203 patients who underwent trabeculectomy at Torfeh and Imam Hossein Medical Centers, Tehran, Iran, between 2016 and 2021. Patients were divided into two groups: those with early bleb leakage (within the 1 month of surgery) and those without bleb leakage.

Article Synopsis
  • The study explored how intranasal air-puffing affects cognitive function and brain activity after a night of partial sleep deprivation in 26 healthy adults.
  • Participants underwent cognitive testing and EEG monitoring, revealing that nasal air-puffs helped reduce cognitive errors and improved response times after sleep deprivation.
  • Nasal air-puffing also restored certain brain activity patterns and complexity that were disrupted by sleep loss, indicating it may help counteract cognitive decline due to lack of sleep.
