Abstract
Hyperlipidemia has been a huge challenge to global health, leading to the cardiovascular disease, hypertension, and diabetes. Atorvastatin calcium (AC), a widely prescribed drug for hyperlipidemia, faces huge challenges with oral administration due to poor water solubility and hepatic first-pass effects, resulting in low therapeutic efficacy. In this work, we designed and developed a hybrid microneedle (MN) patch system constructed with soluble poly(vinyl alcohol) (PVA) and AC-loaded polymeric micelles (AC@PMs) for transdermal delivery of AC to enhance the hyperlipidemia therapy. We first prepared various AC@PM formulations self-assembled from mPEG-PLA and mPEG-PLA-PEG block copolymers using a dialysis method and evaluated the physicochemical properties in combination with experiment skills and dissipative particle dynamics (DPD) simulations. Then, we encapsulated the AC@PMs into the PVA MN patch using a micromold filling method, followed by characterizing the performances, especially the structural stability, mechanical performance, and biosafety. After conducting in vivo experiments using a hyperlipidemic rat model, our findings revealed that the hybrid microneedle-mediated administration exhibited superior therapeutic efficacy when compared to oral delivery methods. In summary, we have successfully developed a hybrid microneedle (MN) patch system that holds promising potential for the efficient transdermal delivery of hydrophobic drugs.

Combination use of human menstrual blood stem cell- derived exosomes and hyperbaric oxygen therapy, synergistically promote recovery after spinal cord injury in rats. Tissue Cell 2024; 88:102378.

Abstract
Traumatic spinal cord injury (TSCI) is one of the catastrophic events in the nervous system that leads to the loss of sensory and motor function of the spinal cord at the site of injury. Considering that several factors such as apoptosis, inflammation, and oxidative stress play a role in the spread of damage caused by trauma, therefore, the treatment should also be based on multifactorial approaches. Currently, we investigated the effects of human menstrual blood stem cells (MenSCs)-derived exosomes in combination with hyperbaric oxygen therapy (HBOT) in the recovery of TSCI in rats. Ninety male mature Sprague-Dawley (SD) rats were planned into five equal groups, including; control group, TSCI group, Exo group (underwent TSCI and received MenSCs -derived exosomes), HBOT group (underwent TSCI and received HBOT), and Exo+HBOT group (underwent TSCI and received MenSCs -derived exosomes plus HBOT). After the behavioral evaluation, tissue samples were obtained for stereological, immunohistochemical, biochemical, and molecular assessments. Our results showed that the numerical density of neurons, the concentrations of antioxidative biomarkers (CAT, GSH, and SOD), and neurological function scores were significantly greater in the treatments group than in the TSCI group, and these changes were more obvious in the Exo+HBOT ones (P<0.05). This is while the numerical densities of apoptotic cells and glial cells, the levels of an oxidative factor (MDA) and proinflammatory cytokines (IL-1β and TNF-α) were considerably decreased in the treatment groups, specially the Exo+HBOT group, compared to the TSCI group (P<0.05). We conclude that the co-administration of exosomes derived from MenSCs and HBOT has more neuroprotective effects in animals with TSCI.

Eur J Pharmacol 2024; 971:176541. [PMID: 38556120 DOI: 10.1016/j.ejphar.2024.176541] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2024] [Revised: 03/22/2024] [Accepted: 03/26/2024] [Indexed: 04/02/2024]
Abstract
Spinal cord injury (SCI), a fatal condition, is characterized by progressive tissue degradation and extreme functional deficits with limited treatment options. Hesperetin, a natural flavonoid with potent antioxidant, antiapoptotic and anti-inflammatory properties, has yet to be systematically investigated for its therapeutic effects on neurological damage in rat models of SCI. In this study, rats were given oral hesperetin once daily for 28 days, and their locomotion and histopathological changes were assessed. The findings demonstrated that hesperetin alleviates neurological damage caused by SCI. The observed behavioral improvement could be due to an increase in the survival rate of neurons and oligodendrocytes. This improvement further boosted the ability to repair tissue and form myelin after SCI, ultimately resulting in better neurological outcomes. Furthermore, the present study revealed that hesperetin possesses potent antioxidant capabilities in the context of SCI, reducing the levels of harmful oxygen free radicals and increasing the activity of antioxidant enzymes. Additionally, hesperetin markedly inhibited injury-induced apoptosis, as assessed by caspase-3 immunofluorescence staining and the expression level of caspase-3, indicating the ability of hesperetin to prevent cell death after SCI. Finally, after SCI, hesperetin treatment effectively reduced the expression of inflammatory factors, including IL-1β, TNFα, and NF-kB, demonstrating the anti-inflammatory effect of hesperetin. Together, our results suggest that hesperetin should be considered a valuable therapeutic aid following SCI, as its positive effects on the nervous system, including antioxidant, anti-inflammatory and antiapoptotic effects, may be crucial mechanisms through which hesperetin exerts neuroprotective effects against SCI.

Abstract
BACKGROUND Chronic use of tramadol can cause neurotoxic effects and subsequently cause neurodegeneration in the cerebellum. The main damage mechanisms identified are oxidative stress and inflammation. Currently, we investigated the effects of coenzyme Q10 (CoQ10) in attenuates of neurodegeneration in the cerebellum induced by chronic exposure to tramadol. MATERIAL AND METHODS Seventy-two male mature albino rats were allocated into four equal groups, including; non-treated group, CoQ10 group (which received CoQ10 at 200 mg/kg/day orally for three weeks), tramadol group (which received tramadol hydrochloride at 50 mg/kg/day orally for three weeks), and tramadol+CoQ10 group (which received tramadol and CoQ10 at the same doses as the previous groups). Tissue samples were obtained for stereological, immunohistochemical, biochemical, and molecular evaluations. Also, functional tests were performed to evaluate behavioral properties. RESULTS We found a significant increase in stereological parameters, antioxidant factors (catalase, glutathione, and superoxide dismutase), and behavioral function scores in the tramadol+CoQ10 group compared to the tramadol group (p < 0.05). In addition, malondialdehyde levels, the density of apoptotic cells, as well as the expression of pro-inflammatory (tumor necrosis factor-alpha, interleukin 1 beta, and interleukin 6) and autophagy (lysosome-associated membrane protein 2, autophagy-related 5, beclin 1, and autophagy-related 12) genes were considerably reduced in the tramadol+CoQ10 group compared to the tramadol group (p < 0.05). CONCLUSION We conclude that the administration of CoQ10 has neuroprotective effects in the cerebellum of rats that have chronic exposure to tramadol.

Abstract
BACKGROUND Traumatic brain injury (TBI) is an important and growing cause of disability worldwide, and its cognitive consequences may be particularly significant. This study assessed the neuroprotective impacts of estradiol (E2), myrtenol (Myr), and the combination of the two on the neurological outcome, hemodynamic parameters, learning and memory, brain-derived neurotrophic factor (BDNF) level, phosphoinositide 3-kinases (PI3K/AKT) signaling, and inflammatory and oxidative factors in the hippocampus after TBI. METHODS Eighty-four adult male Wistar rats were randomly divided into 12 groups with seven rats in each (six groups to measure intracranial pressure, cerebral perfusion pressure, brain water content, and veterinary coma scale, and six groups for behavioral and molecular studies): sham, TBI, TBI/vehicle, TBI/Myr, TBI/E2, and TBI/Myr + E2 (Myr 50 mg/kg and E2 33.3 μg/kg via inhalation for 30 min after TBI induction). Brain injury was induced by using Marmarou's method. Briefly, a 300-g weight was dropped down from a 2-m height through a free-falling tube onto the head of the anesthetized animals. RESULTS Veterinary coma scale, learning and memory, brain water content, intracranial pressure, and cerebral perfusion pressure were impaired following TBI, and inflammation and oxidative stress were raised in the hippocampus after TBI. The BDNF level and PI3K/AKT signaling were impaired due to TBI. Inhalation of Myr and E2 had protective effects against all negative consequences of TBI by decreasing brain edema and the hippocampal content of inflammatory and oxidant factors and also by improving BDNF and PI3K/AKT in the hippocampus. Based on these data, there were no differences between alone and combination administrations. CONCLUSIONS Our results propose that Myr and E2 have neuroprotective effects on cognition impairments due to TBI.

Abstract
Spinal cord injury (SCI) following trauma is a devastating neurological event that can lead to loss of sensory and motor functions. However, the most effective measures to prevent the spread of damage are treatment measures in the early stages. Currently, we investigated the combined effects of hyperbaric oxygen (HBO) along with epigallocatechin-3-gallate (EGCG) in the recovery of SCI in rats. Ninety male mature Sprague-Dawley rats were randomly planned into five equal groups (n = 18). In addition to sham group that only underwent laminectomy, SCI rats were allocated into 4 groups as follows: control group; HBO group; EGCG group; and HBO + EGCG group. Tissue samples at the lesion site were obtained for stereological, immunohistochemical, biochemical, and molecular evaluation. In addition, behavioral tests were performed to assess of neurological functions. The finding indicated that the stereological parameters, antioxidant factors (CAT, GSH, and SOD), IL-10 gene expression levels and neurological functions were considerably increased in the treatment groups in comparison with control group, and these changes were more obvious in the HBO + EGCG group (P < 0.05). On the other hand, we observed that the density of apoptotic cells and gliosis, the biochemical levels of MDA and the expression levels of inflammatory genes (TNF-α and IL-1β) in the treatment groups, especially the HBO + EGCG group, were considerably reduced in comparison with control group (P < 0.05). We conclude that co-administration of HBO and EGCG has a synergistic neuroprotective effects in animals undergoing SCI.

Abstract
The most important factors in the non-optimal healing of diabetic wounds are the lack of a suitable scaffold in the wound site for the migration and replacement of cells, as well as the lack of blood supply and effective growth factors in the wound site. Herein we investigated whether a bioengineered micro-porous three-dimensional decellularized amniotic membrane-scaffold (DAMS) in combination with adipose-derived stem cells (ASCs) could promote healing in ischemic wounds in diabetic type 1 rat. The diabetic animals were randomly divided into non-treated (untreated group), engraftment by DAMS (DAMS group), transplanted by ASCs (ASC group), and DAMS in combination with ASCs (DAMS+ASC group). Stereological, immunohistochemical, molecular, and tensiometrical assessments were performed on post-surgical days 7, 14, and 21. We found that the rate of wound closure, the volumes of new epidermis and dermis, the numerical density of fibroblasts and blood vessels, the numbers of proliferating cells and collagen deposition as well as biomechanical properties of the healed wounds were significantly higher in the treatment groups in comparison to the untreated group, and were the highest in DAMS+ASC ones. The transcripts for TGF-β and VEGF genes were significantly upregulated in all treatment regimens compared to the untreated group and were the highest for DAMS+ASC group. This is while expression of TNF-α and IL-1β as well as cell density of neutrophils decreased more significantly in DAMS+ASC group as compared with other groups. Overall, it was found that using both DAMS engraftment and ASC transplantation has more impact on diabetic wound healing.

Abstract
BACKGROUND Oxidative stress, inflammation and cell apoptosis are the most important destructive factors in the spread of damage following trauma to the spinal cord. Therefore, presently, we investigated the synergistic effects of quercetin along with hyperbaric oxygen therapy (HBOT) as strong antioxidant, anti-inflammatory and anti-apoptotic compounds in the recovery of traumatic spinal cord injury (TSCI) in a rat model. MATERIAL AND METHODS Seventy-five male mature Sprague-Dawley rats allocated into 5 groups, including: Sham group (SG), TSCI group, Quercetin group (underwent TSCI and received quercetin), HBOT group (underwent TSCI and received HBOT), and Quercetin+ HBOT group (underwent TSCI and received quercetin plus HBOT). Finally, the spinal cord samples at the traumatic site were harvested and various characteristics were evaluated, including the total volumes of the spinal cord and its central cavity as well as the numerical density of neuron and glial cells by stereological method, oxidant (malondialdehyde; MDA) and antioxidant (glutathione; GSH, superoxide dismutase; SOD and catalase; CAT) factors by biochemical method, molecular levels of IL-10, TNF-α and IL-1β by qRT-PCR method, and cell apoptosis by immunohistochemistry method against Caspase-3 antibody. Furthermore, Basso-Beattie-Bresnahan (BBB) and electromyography latency (EMG Latency) tests were performed to evaluate neurological functions. RESULTS Findings demonstrated that the stereological characteristics, biochemical factors (except MDA), expression of IL-10 gene and behavioral functions were significantly better in Quercetin, HBOT and Quercetin+HBOT groups than TSCI group, and were greater in Quercetin+HBOT ones (P < 0.05). While MDA levels, expression of TNF-α and IL-1β genes as well as the density of apoptotic cells significantly more decreased in Quercetin+HBOT group compared to other treated groups (P < 0.05). CONCLUSION Overall, co-administration of quercetin with HBOT has synergistic neuroprotective effects in animals underwent TSCI.

Abstract
Spinal cord injury (SCI) is a devastating neurological condition prevalent worldwide. Where the pathological mechanisms underlying SCI are concerned, we can distinguish between primary injury caused by initial mechanical damage and secondary injury characterized by a series of biological responses, such as vascular dysfunction, oxidative stress, neurotransmitter toxicity, lipid peroxidation, and immune-inflammatory response. Secondary injury causes further tissue loss and dysfunction, and the immune response appears to be the key molecular mechanism affecting injured tissue regeneration and functional recovery from SCI. Immune response after SCI involves the activation of different immune cells and the production of immunity-associated chemicals. With the development of new biological technologies, such as transcriptomics, the heterogeneity of immune cells and chemicals can be classified with greater precision. In this review, we focus on the current understanding of the heterogeneity of these immune components and the roles they play in SCI, including reactive astrogliosis and glial scar formation, neutrophil migration, macrophage transformation, resident microglia activation and proliferation, and the humoral immunity mediated by T and B cells. We also summarize findings from clinical trials of immunomodulatory therapies for SCI and briefly review promising therapeutic drugs currently being researched.
