Aim: The aim of this study is to evaluate radioprotective effects of Cerebrolysin (CBL) in rats' brain tissues after local irradiation.
Background: CBL has demonstrated antioxidant, anti-inflammatory, and tissue repair properties. In this study, the radioprotective effects of CBL in the brain tissues of rats after Irradiation (IR) (50 mg/ kg) were evaluated.
Objective: The levels of different oxidative stress markers, including malondialdehyde (MDA), nitric oxide (NO), glutathione peroxidase (GPx), catalase (CAT), and superoxide dismutase (SOD) were examined after treatment with radiation and CBL.
Methods: First, 20 male adult Wistar rats weighing 180-200 g were used. The animals were exposed to a single fraction of 15Gy using a linear accelerator unit at a dose rate of 200 cGy/mine. In this study, to check the amount of oxidative stress following the IR, the level of four markers MDA, NO, GPx, CAT, and SOD were examined and measured using the spectrophotometric method and purchased kits.
Results: The results showed that compared to the IR group, the administration of CBL increases the levels of GPX and SOD significantly (p < 0.05).
Conclusion: Our finding suggests that CBL has radioprotective effects on the brain by enhancing antioxidant defense mechanisms.

Clinical research in boron neutron capture therapy (BNCT) has been conducted worldwide. Currently, the Monte Carlo (MC) method is the only dose calculation algorithm implemented in the treatment planning system for the clinical treatment of BNCT. We previously developed the MC-RD calculation method, which combines the MC method and the removal-diffusion (RD) equation, for fast dose calculation in BNCT.

Background: Red blood cell (RBC) aggregation can be initiated by calcium and tissue factor, which may independently contribute to microvascular and macrovascular thrombosis after injury and transfusion. Previous studies have demonstrated that increased blood storage duration may contribute to thrombotic events. The aims of this study were to first determine the effect of blood product components, age, and hematocrit (HCT) on the aggregability of RBCs, followed by measurement of RBC aggregability in two specific injury models including traumatic brain injury (TBI) and hemorrhagic shock.

Median craniofacial hypoplasia is characterized by tissue deficiency of the midline facial structures and/or brain. Patients can present with a wide variety of facial differences that may or may not require operative intervention. Common reconstructive procedures include cleft lip and/or palate repair, rhinoplasty, and orthognathic surgery, among others.

ING5 targets Moz/Morf and HBO1 HAT complexes that alter acetylation of H3 and H4 core histones, affecting gene expression. Previous experiments in vitro indicated that ING5 functions to maintain stem cell character in normal and in cancer stem cells.

Oxidative stress and neuroinflammation play a pivotal role in pathomechanisms of brain ischemia. Our research aimed to formulate a nanotheranostic system for delivering carnosic acid as a neuroprotective agent with anti-oxidative and anti-inflammatory properties to ischemic brain tissue, mimicked by organotypic hippocampal cultures (OHCs) exposed to oxygen-glucose deprivation (OGD). In the first part of this study, the nanocarriers were formulated by encapsulating two types of nanocores (nanoemulsion (AOT) and polymeric (PCL)) containing CA into multilayer shells using the sequential adsorption of charged nanoobjects method.
