    Abstract Ischemic stroke resulting from blockade of brain vessels lacks effective treatments, prompting exploration for potential therapies. Among promising candidates, microRNA-149 (miR-149) has been investigated for its role in alleviating oxidative stress, inflammation, and neurodegeneration associated with ischemic conditions. To evaluate its therapeutic effect, male Wistar rats were categorized into five groups, each consisting of 27 rats: sham, MCAO, lentiviral control, lentiviral miR-149, and miR149-5p mimic. Treatments were microinjected intracerebroventricularly (ICV) (right side), and ischemia was induced using middle cerebral artery occlusion (MCAO) procedure. Post-MCAO, neurological function, histopathological changes, blood-brain barrier (BBB) permeability, cerebral edema, and mRNA levels of Fas ligand (Faslg) and glutamate ionotropic NMDA receptor 1 (GRIN1) were assessed, alongside biochemical assays. MiR-149 administration improved neurological function, reduced brain damage, preserved BBB integrity, and attenuated cerebral edema. Upregulation of miR149-5p decreased Faslg and GRIN1 expression in ischemic brain regions. MiR-149 also reduced oxidative stress, enhanced antioxidant activity, decreased caspase-1 and - 3 activity, and modulated inflammatory factors in ischemic brain regions. Moreover, DNA fragmentation as an index of cell death decreased following miR-149 treatment. In conclusion, the study underscores miR-149 potential as a neuroprotective agent against ischemic stroke, showcasing its efficacy in modulating various mechanisms and supporting its candidacy as a promising therapeutic target for innovative strategies in stroke treatment.

    Abstract It has been proven that olive associated products such as olive leaf extract (OLE) causes significant reduction in cancer cells viability and proliferation. Female BALB/c adult mice were divided into four groups. Three days prior to oral treatments, tumors were transplanted. First group were treated with distilled water and other three groups were received, respectively, 75, 150, and 225 mg/kg/day of OLE for three weeks. For assessment of anti-angiogenesis and pro-apoptotic effect of OLE on tumor tissue, tumor volume, cell mitosis and apoptosis, and also vascular endothelial growth factor (VEGF) and endostatin levels were assessed. OLE treatment with 150 and 225 mg/kg/day lead to significant reduction in tumor volume and cell mitosis compared with the control group, while the same doses significantly increase tumor cell apoptosis. OLE treatment with 150 mg/kg/day increase endostatin levels, while the same dose did not significantly decrease VEGF levels. The VEGF level is significantly reduced by the treatment with OLE 225 mg/kg/day for three weeks. Although, further studies are needed to clarify anti-angiogenesis and anti-apoptotic mechanism of OLE, consumption of OLE polyphenols after tumor transplantation reduced spontaneous mouse mammary tumor growth.

    Abstract A ratiometric fluorescent nanoprobe is developed with a wide color variation for visual determination of spermine (SP) and spermidine (SD) in meat samples. The green emission provided from the combination of yellow emissive quantum dots and blue emissive carbon dots turns into pink when SP or SD are present. The results show that the developed sensor has good linearity in the range of 0.5-10 and 0.5-80 µM for SP and SD and suitable detection limits were achieved including 0.2 and 2.1 µM for SP and SD. The probe was highly selective in the presence of amino acids and other biogenic amines. RGB indices were extracted to build a combinational logic gate for visual and simultaneous detection of SP and SD. The dual functional logic gate was easy to design and convenient to operate. Finally, a portable sensor was fabricated for visual, rapid and on-site assessment of meat freshness.

    Plain language summary: A stroke is a medical condition in which poor blood flow to the brain results in cell death. After an interruption of blood flow, energy stores are rapidly depleted, and complex cellular cascades induce excitotoxic cell death. So far, no effective and specific treatment has been suggested for the stroke. In this study, the neuroprotective effects of the viola odorata extract (VOE) were screened. The V. odorata extract exhibited excellent neuroprotective effects by reducing infarct volume and inducing downregulation of

    Abstract Blood-brain barrier (BBB) disruption, inflammation, and cell death are the pathogenic mechanisms of cerebral ischemia/reperfusion (I/R) injury. Nicorandil protects ischemic injury via some of these mechanisms. The aim of this study was to investigate the therapeutic effects of this drug on the brain ischemia after transient middle cerebral artery occlusion (MCAO) and clarify the NF-jB and Nrf2-dependent mechanisms modulated by this drug. Sixty-six rats were randomized into sham, MCAO and MCAO + nicorandil groups with oral gavage for 3 days. Cerebral I/R injury were induced by a transient MCAO for 1 h and neurobehavioral scores were performed for 3 days. In addition to measurement of BBB disruption and brain water content, the total and infarct volume, density, and total number of neurons, non-neurons and dead neurons in the right cortex were estimated by unbiased stereological methods. RT-PCR was performed to analyze the expression levels of NFjB and Nrf2. Although nicorandil treatment in the sub-acute brain ischemia did not have a prominent effect on neurobehavioral function and number of neurons, non-neurons and dead neurons probably through up-regulation of NF-jB, it, however, improved ischemia-induced BBB disruption and brain edema and showed a significant reduction in the infarction volume probably through up-regulation of Nrf2.

    Abstract Background and purpose: Oxidative stress and neuroinflammation are the main causes of cerebral ischemia. Saponin with steroid or triterpenoid compounds with a sugar part has strong antioxidant and anti-inflammatory properties. The aim of this study was to evaluate the effect of saponin on cerebral edema, Bax gene expression level, and ischemic neurological defects. Materials and methods: In this experimental study, 24 male Wistar rats were divided into three groups: sham, stroke, and stroke+saponin. Rats in the stroke+saponin group received intravenous injection of saponin (3mg/kg) 30 minutes before cerebral ischemia. Each group was divided into two subgroups: brain edema (n=5) and gene expression level investigation (n=3). Cerebral ischemia was induced by middle cerebral artery occlusion model. After 24 hrs, we investigated neurological deficits resulting from ischemia (Kruskal-Wallis test), the degree of brain edema, and Bax gene expression levels in the cortex, piriform cortex-amygdala, striatum, and hippocampus (one-way ANOVA). Results: Findings indicated a significant decrease in the score of neurological defects resulting from ischemia, the amount of cerebral edema, and the level of Bax gene expression in stroke+saponin group (P<0.05). Conclusion: This study showed that saponin pretreatment in rats with ischemia-reperfusion injury can be effective in reducing the damage caused by cerebral ischemia.

    Abstract Background: The therapeutic effects of dimethyl fumarate (DMF) in patients with multiple sclerosis and animal models of neurologic disease were reported. The density and the distribution pattern of motor neurons are important in transmitting the signal and controlling the movement-related functions. The present study evaluated the effects of DMF treatment on the neurological functions, infarct volume, and spatial distribution of the neurons in the primary motor cortex after cerebral ischemia.
    Methods: Thirty-three Sprague-Dawley rats were randomly divided into three groups: The sham group underwent surgery without middle cerebral artery occlusion (MCAO) and drug. The vehicle and treatment groups after MCAO received a vehicle or DMF for three consecutive days. Post-stroke neurological and motor functions were assessed. At the end of the third day, the brains were removed, and the cerebral infarct volume was evaluated. We used cresyl violet staining to analyze the density and the spatial arrangement of motor cortical neurons using Voronoi tessellation.
    Results: Treatment of the brain ischemia for three days with DMF could not significantly reduce the neurological and motor function deficits and infarct volume. However, it reduced the neuronal area and death and preserved their spatial distribution in the normal regular pattern.
    Conclusion: Cerebral ischemia decreased the neuronal density of the primary motor cortex and changed their distributions to a random pattern. DMF treatment during sub-acute ischemic stroke did not significantly improve the neurological deficit scores. However, it could prevent neuronal swelling and death and preserved the spatial distribution of the cortical neurons in their normal pattern.

    Abstract Introduction: MicroRNAs (miRNAs or miRs) are non-coding RNAs. Studies have shown that miRNAs are expressed aberrantly in stroke. The miR1 enhances ischemic damage, and a previous study has demonstrated that reduction of miR1 level has a neuroprotective effect on the Middle Cerebral Artery Occlusion (MCAO). Since apoptosis is one of the important processes in neural protection, the possible effect of miR1 on this pathway has been tested in this study. Post-ischemic administration of miR1 antagomir reduces infarct volume via bcl-w and bad expression.
    Methods: Rats were divided into four experimental groups: sham, control, positive control, and antagomir treatment group. One hour after MCAO surgery, the rats were received intravenously (Tail vein) 0.1 mL Normal Saline (NS), 0.1 mL rapamycin, and 300 pmol/g miR1 antagomir (soluble in 0.1 mL normal saline) in control, positive control, and treatment group, respectively. Twenty-four hours after reperfusion infarct volume was measured. The expression of miR1, bcl-w, and bad were analyzed using real-time PCR in sham, control, and treated groups.
    Results: Our results indicate that administration of miR1 antagomir reduces infarct volume significantly, it also decreases miR1 and bad expression while increases bcl-w expression.
    Conclusion: Understanding the precise neuroprotective mechanism of miR1 antagomir can make it a proper treatment and an innovative approach for stroke therapy.
