Background: Ellagitannins are well-recognized for their antioxidant, chemopreventive, anti-inflammatory, and neuroprotective efficacy. Due to their poor absorption and extensive catabolism, it is proposed that urolithins, as ellagic acid (EA) metabolites, are the real active molecules exerting these biological functions.

Objectives: This research evaluated the inhibitory effects of EA, urolithin A (Uro A), and urolithin B (Uro B) on the activity of recombinant human matrix metalloproteinase 9 (rhMMP-9).

In the present work, physio-biochemical and DNA methylation analysis were conducted in wheat (Triticum aestivum L.) cultivars "Bolani" (drought-tolerant) and "Sistan" (drought-sensitive) during drought treatments: well-watered (at 90% field capacity (FC)), mild stress (at 50% FC, and severe stress (at 25% FC). During severe stress, O and HO content in cultivar Sistan showed significant increase (by 1.

Introduction: Iron oxide nanoparticles (FeO-NPs) are small magnetic particles that are widely used in different aspects of biology and medicine in modern life. FeO-NP accumulated in the living cells due to the absence of an active system to excrete the iron ions and damages cellular organelles by high reactivity.

Methods: Herein cytotoxic effects of FeO-NP with a size of 50 nm on the primary culture of neonatal rat hippocampus were investigated using 2,5-diphenyltetrazolium bromide (MTT) assay.

Article Synopsis
  • Outer membrane vesicles (OMVs) are nanoparticles produced by gram-negative bacteria, classified into native (nOMVs) and non-native (dOMVs) based on their production methods.
  • OMVs can effectively induce immune responses and have become valuable in biomedical applications, including vaccines for infections and cancer therapy.
  • Various factors like growth conditions, genetic modifications, and stressors can influence OMV production, and recent research explores their use as adjuvants, drug delivery systems, and enzyme carriers.

The hippocampus is a part of the brain's medial temporal lobe that is located under the cortex. It belongs to the limbic system and helps to collect and transfer information from short-term to long-term memory, as well as spatial orientation in each mammalian brain hemisphere. After more than two centuries of research in brain asymmetry, the hippocampus has attracted much attention in the study of brain lateralization.

Objective: Thyroid hormones play an essential role in metabolism regulation and circadian rhythm control. Recent studies approved their role in normal development and healthy function of central nervous system (CNS). The thyroid gland is a component of the hypothalamic-pituitary-thyroid axis disrupted during thyrotoxicosis and hypothyroidism, two main clinical conditions that induce more liability against dementia-related disease.

Background: Advanced age is associated with a decline in the natural oocytes, low oocyte yield, and also increases the assisted reproductive technology (ART) failure rate, and consequently resulted in a pregnancy rate decrease. Platelet-rich plasma (PRP) is one of the proposed therapeutic strategies for women with poor ovarian response (POR). Because of the autologous source of PRP, the lowest risks of disease transmission, immunogenic and allergic reactions have been expected.

Despite the regulatory role of Tau protein in the stabilization and assembly of microtubules, this protein has an important function in the protection and stabilizing of DNA molecules in the cell nucleus. In the present study, it has been indicated that glycation of lysine residues (Lys-267, Lys-274, and Lys-280) in the microtubule-binding domain (MBD) can considerably decrease its binding affinity to DNA molecules. The structural analysis also confirmed that the decreased glycated tau-DNA complex's stability was due to structural modification of this protein after the glycation process.

Herein proteomic profiling of the rat hippocampus from the kindling and pilocarpine models of epilepsy was performed to achieve new potential targets for treating epileptic seizures. A total of 144 differently expressed proteins in both left and right hippocampi by two-dimensional electrophoresis coupled to matrix-assisted laser desorption-mass spectrometry were identified across the rat models of epilepsy. Based on network analysis, the majority of differentially expressed proteins were associated with Ca homeostasis.

Article Synopsis
  • The study focused on Iranian HIV-1-infected patients with low CD4+ counts (<100 cells/mm³) to evaluate the presence of cytomegalovirus (CMV) viremia and its relationship with CD4+ counts and retinitis.
  • Out of 82 patients, 39 exhibited detectable CMV viral loads, with those experiencing retinitis having higher viral loads compared to others; however, no significant link was found between CMV levels and CD4+ counts.
  • The findings indicate a need for further research on CMV viral load's role in diagnosing and predicting outcomes for patients with CMV end-organ disease (CMV-EOD) in the context of HIV infection.
