Abstract
BACKGROUND Radiotherapy (RT) is a feasible adjuvant therapeutic option for managing intracranial pathologies. One of the late complications of RT that frequently develops within months following RT is radiation necrosis (RN). Corticosteroids are the first-line therapeutic option for RNs; however, in case of unfavorable outcomes or intolerability, several other options, including bevacizumab, laser interstitial thermal therapy, surgery, and hyperbaric oxygen therapy (HBOT). Our goal was to investigate the feasibility and efficacy of the application of HBOT in RNs following RT and help physicians make decisions based on the latest data in the literature. METHODS We provide a comprehensive review of the literature on the current issues of utilization of HBOT in RNs. RESULTS We included 11 studies with a total of 46 patients who underwent HBOT. Most of the cases were diagnosed with brain tumors or arteriovenous malformations. Improvement was achieved in most of the cases. DISCUSSION HBOT is a noninvasive therapeutic intervention that can play a role in adjuvant therapy concurrent with RT and chemotherapy and treating RNs. HBOT resolves the RN through 3 mechanisms, including angiogenesis, anti-inflammatory modulation, and cellular repair. Previous studies demonstrated that HBOT is a feasible and well-tolerated therapeutic option that has shown promising results in improving clinical and radiological outcomes in intracranial RNs. Complications of HBOT are usually mild and reversible. CONCLUSIONS HBOT is a feasible and effective therapeutic option in steroid-refractory RNs and is associated with favorable outcomes and a low rate of side effects.

Abstract
Objective To evaluate the potential benefits of hyperbaric oxygen intervention on people with Alzheimer's disease (AD) based on the existing randomized controlled trials (RCTs). Methods A systematic search was conducted in nine databases until November 17, 2023, for RCTs assessing the effect of hyperbaric oxygen intervention for AD. The primary outcomes included Mini-Mental State Examination (MMSE), Alzheimer's Disease Assessment Scale-Cognitive (ADAS-Cog), activities of daily living (ADL), and adverse events. All results were shown in forest plots, and sensitivity analysis was adopted to further verify the robustness of the pooled results. Results A total of 11 RCTs recruiting 847 participants were included in this meta-analysis. Based on the pooled evidence, hyperbaric oxygen could remarkably ameliorate MMSE [MD = 3.08, 95%CI (2.56, 3.61), p < 0.00001], ADAS-Cog [MD = -4.53, 95%CI (-5.05, -4.00), p < 0.00001], ADL [MD = 10.12, 95%CI (4.46, 15.79), p = 0.0005], MDA levels [SMD = -2.83, 95%CI (-5.27, -0.38), p = 0.02], SOD levels [SMD = 2.12, 95%CI (1.10, 3.15), p < 0.0001], IL-1-β levels [SMD = -1.00, 95%CI (-1.48, -0.53), p < 0.0001], and TGF-β1 levels [MD = 4.87, 95%CI (3.98, 5.76), p < 0.00001] without adverse events [OR = 1.17, 95%CI (0.68, 2.03), p = 0.58] for people with AD. The pooled results were robust after checking by sensitivity analysis. Conclusion These evidences suggest that hyperbaric oxygen is an effective and safe intervention for the treatment of AD. Further studies with more rigorous design will help to fully evaluate the clinical value of hyperbaric oxygen on cognition function in people with AD.

Abstract
INTRODUCTION Vascular cognitive impairment (VCI) has an increasing prevalence worldwide, accounting for at least 20%-40% of all diagnoses of dementia. The decline in cognitive function seriously impairs patients' activities of daily living and social participation and reduces their quality of life. However, there is still a lack of advanced, definitive rehabilitation programmes for VCI. Hyperbaric oxygen therapy (HBOT) and repetitive transcranial magnetic stimulation (rTMS) are recognised treatments for improving cognitive impairment. The former can restore oxygen supply in the brain by increasing oxygen partial pressure in brain tissue, while the latter can enhance neuronal excitability and promote synaptic plasticity. However, no studies have explored the effect of HBO combined with rTMS on VCI. METHODS AND ANALYSIS This study is designed as a single-centre, assessor-blind, randomised controlled clinical trial with four parallel arms. A total of 72 participants will be recruited and randomly assigned to the control group, HBOT group, rTMS group and HBOT combined with rTMS group at a ratio of 1:1:1:1. All enrolled participants will receive conventional treatment. The entire intervention period is 4 weeks, with a 3-week follow-up. Outcomes will be measured at baseline (T0), after a 4-week intervention (T1) and after an additional 3-week follow-up period (T2). The primary endpoint is the Montreal Cognitive Assessment score. The secondary endpoints are Mini-Mental State Examination score, Modified Barthel Index score, latency and amplitude of P300, cerebral cortical oxygenated haemoglobin (HbO2) and deoxygenated haemoglobin (HbR) concentrations as measured by task-state functional near-infrared spectroscopy. ETHICS AND DISSEMINATION Ethics approval was obtained from the West China Hospital Clinical Trials and Biomedical Ethics Committee of Sichuan University (ethics reference: 2022 (1972)). The findings will be published in peer-reviewed journals and disseminated through scientific conferences and seminars. TRIAL REGISTRATION NUMBER ChiCTR2300068242.

Abstract
Alzheimer’s disease (AD) is a degenerative neurological disease that primarily affects the elderly. Drug therapy is the main strategy for AD treatment, but current treatments suffer from poor efficacy and a number of side effects. Non-drug therapy is attracting more attention and may be a better strategy for treatment of AD. Hypoxia is one of the important factors that contribute to the pathogenesis of AD. Multiple cellular processes synergistically promote hypoxia, including aging, hypertension, diabetes, hypoxia/obstructive sleep apnea, obesity, and traumatic brain injury. Increasing evidence has shown that hypoxia may affect multiple pathological aspects of AD, such as amyloid-beta metabolism, tau phosphorylation, autophagy, neuroinflammation, oxidative stress, endoplasmic reticulum stress, and mitochondrial and synaptic dysfunction. Treatments targeting hypoxia may delay or mitigate the progression of AD. Numerous studies have shown that oxygen therapy could improve the risk factors and clinical symptoms of AD. Increasing evidence also suggests that oxygen therapy may improve many pathological aspects of AD including amyloid-beta metabolism, tau phosphorylation, neuroinflammation, neuronal apoptosis, oxidative stress, neurotrophic factors, mitochondrial function, cerebral blood volume, and protein synthesis. In this review, we summarized the effects of oxygen therapy on AD pathogenesis and the mechanisms underlying these alterations. We expect that this review can benefit future clinical applications and therapy strategies on oxygen therapy for AD.

Abstract
Different investigations lead to the urgent need to generate validated clinical protocols as a tool for medical doctors to orientate patients under risk for a preventive approach to control Alzheimer's disease. Moreover, there is consensus that the combined effects of risk factors for the disease can be modified according to lifestyle, thus controlling at least 40% of cases. The other fraction of cases are derived from candidate genes and epigenetic components as a relevant factor in AD pathogenesis. At this point, it appears to be of critical relevance the search for molecular biomarkers that may provide information on probable pathological events and alert about early detectable risks to prevent symptomatic events of the disease. These precocious detection markers will then allow early interventions of non-symptomatic subjects at risk. Here, we summarize the status and potential avenues of prevention and highlight the usefulness of biological and reliable markers for AD.

Abstract
The World Health Organization estimates that by the year 2040, neurodegenerative diseases will be the second leading cause of death in developed countries, overtaking cancer-related deaths and exceeded only by cardiovascular disease-related death. The search for interventions has therefore become paramount to alleviate some of this burden. Based on pathways affected in neurodegenerative diseases, hyperbaric oxygen treatment (HBOT) could be a good candidate. This therapy has been used for the past 50 years for conditions such as decompression sickness and wound healing and has been shown to have promising effects in conditions associated with neurodegeneration and functional impairments. The goal of this review was to explore the history of hyperbaric oxygen therapy, its uses, and benefits, and to evaluate its effectiveness as an intervention in treating neurodegenerative diseases. Additionally, we examined common mechanisms underlying the effects of HBOT in different neurodegenerative diseases, with a special emphasis on epigenetics.

Abstract
Alzheimer's disease and related dementias (ADRD) are an expanding worldwide crisis. In the absence of scientific breakthroughs, the global prevalence of ADRD will continue to increase as more people are living longer. Racial or ethnic minority groups have an increased risk and incidence of ADRD and have often been neglected by the scientific research community. There is mounting evidence that vascular insults in the brain can initiate a series of biological events leading to neurodegeneration, cognitive impairment, and ADRD. We are a group of researchers interested in developing and expanding ADRD research, with an emphasis on vascular contributions to dementia, to serve our local diverse community. Toward this goal, the primary objective of this review was to investigate and better understand health disparities in Alabama and the contributions of the social determinants of health to those disparities, particularly in the context of vascular dysfunction in ADRD. Here, we explain the neurovascular dysfunction associated with Alzheimer's disease (AD) as well as the intrinsic and extrinsic risk factors contributing to dysfunction of the neurovascular unit (NVU). Next, we ascertain ethnoregional health disparities of individuals living in Alabama, as well as relevant vascular risk factors linked to AD. We also discuss current pharmaceutical and non-pharmaceutical treatment options for neurovascular dysfunction, mild cognitive impairment (MCI) and AD, including relevant studies and ongoing clinical trials. Overall, individuals in Alabama are adversely affected by social and structural determinants of health leading to health disparities, driven by rurality, ethnic minority status, and lower socioeconomic status (SES). In general, these communities have limited access to healthcare and healthy food and other amenities resulting in decreased opportunities for early diagnosis of and pharmaceutical treatments for ADRD. Although this review is focused on the current state of health disparities of ADRD patients in Alabama, future studies must include diversity of race, ethnicity, and region to best be able to treat all individuals affected by ADRD.

Abstract
Hyperbaric oxygen therapy (HBOT) is a modality of treatment in which patients inhale 100% oxygen inside a hyperbaric chamber pressurised to greater than 1 atmosphere. The aim of this review is to discuss neuropsychological findings in various neurological disorders treated with HBOT and to open new perspectives for therapeutic improvement. A literature search was conducted in the MEDLINE (via PubMed) database from the inception up 10 May 2020. Eligibility criteria included original articles published in English. Case studies were excluded. Full-text articles were obtained from the selected studies and were reviewed on the following inclusion criteria (1) performed cognitive processes assessment (2) performed HBOT with described protocol. Two neuropsychologists independently reviewed titles, abstracts, full texts and extracted data. The initial search retrieved 1024 articles, and a total of 42 studies were finally included after applying inclusion and exclusion criteria. The search yielded controversial results with regard to the efficiency of HBOT in various neurological conditions with cognitive disturbance outcome. To the best of our knowledge this is the first state-of-the art, systematic review in the field. More objective and precise neuropsychological assessment methods are needed to exact evaluation of the efficacy of HBOT for neuropsychological deficits. Future studies should widen the assessment of HBOT effects on different cognitive domains because most of the existing studies have focussed on a single process. Finally, there is a need for further longitudinal studies.

Abstract
Fingolimod (FTY720) is a sphingosine 1-phosphate (S1P) receptor agonist. Here, to understand biological activity of FTY720 pretreatment and post-treatment on cerebral ischemia reperfusion injury (CIRI), rat transient middle cerebral artery occlusion/reperfusion (tMCAO/R) model was generated. Neurological deficit scoring was assessed after tMCAO/R. Four groups were established including sham-operated control group, operated group, and two FTY720-treated groups. Neuron damage was observed by Nissl staining. Gene expression was measured using qPCR and western blot analysis. Tumor necrosis factor α (TNF-α), interleukin 1β (IL-1β) and interleukin 6 (IL-6) levels were evaluated by enzyme-linked immunosorbent assay (ELISA). We uncovered that neurological score in two FTY720-treated groups was significantly lower than that in the operated group. FTY720 pretreatment or posttreatment groups had a significantly increased number of Nissl bodies in cerebral cortex as compared with the operated group, indicating that FTY720 administration reduced neuronal damage. Besides, FTY720 posttreatment improved memory impairment induced by tMCAO/R. In addition, IL-1β, IL-6, and TNF-α levels in the cerebral cortex and hippocampus of two FTY720-treated groups were significantly decreased in comparison to the operated group, showing that FTY720 could reduce the release of inflammatory cytokines in brain tissue. Furthermore, phosphorylation of p38MAPK and NF-κB pathway-related molecules in ischemic brain tissues of FTY720 group were markedly down-regulated compared to the operated group. Together, FTY720 pretreatment or posttreatment improved the neurological deficit of middle cerebral ischemia/reperfusion rat model and reduced neuronal damage by decreasing the levels of inflammatory cytokines and attenuating the phosphorylation levels of p38MAPK and NF-κB pathway-associated molecules. FTY720 exhibits neuroprotective effects against ischemic reperfusion injury in rats.

Abstract
Hyperbaric oxygen treatment (HBOT)—the medical use of oxygen at environmental pressure greater than one atmosphere absolute—is a very effective therapy for several approved clinical situations, such as carbon monoxide intoxication, incurable diabetes or radiation-injury wounds, and smoke inhalation. In recent years, it has also been used to improve cognition, neuro-wellness, and quality of life following brain trauma and stroke. This opens new avenues for the elderly, including the treatment of neurological and neurodegenerative diseases and improvement of cognition and brain metabolism in cases of mild cognitive impairment. Alongside its integration into clinics, basic research studies have elucidated HBOT’s mechanisms of action and its effects on cellular processes, transcription factors, mitochondrial function, oxidative stress, and inflammation. Therefore, HBOT is becoming a major player in 21st century research and clinical treatments. The following review will discuss the basic mechanisms of HBOT, and its effects on cellular processes, cognition, and brain disorders.

The activation of spinal astrocytes and release of neuroinflammatory mediators are important events in neuropathic pain (NP) pathogenesis. In this study, we investigated the role of Wnt10a/β-catenin signalling in kindlin-1-mediated astrocyte activation using a chronic constriction injury (CCI) NP rat model. Using kindlin-1 overexpression and knockdown plasmids, we assessed hyperalgesia, changes in spinal astrocyte activation and the release of inflammatory mediators in a NP rat model. We also performed coimmunoprecipitation, Western blotting and real-time polymerase chain reaction (PCR) to characterize the underlying mechanisms of kindlin-1 in astrocyte cultures in vitro. Kindlin-1 was significantly upregulated in CCI rats and promoted hyperalgesia. Moreover, we observed increased kindlin-1, Wnt10a and glial fibrillary acidic protein (GFAP; biomarker for astroglial injury) levels and the release of inflammatory mediators in NP rats (p < 0.05). Inhibiting GFAP in vitro led to decreased kindlin-1 levels, prevented astrocyte activation, decreased Wnt10a level and the release of inflammatory mediators (p < 0.05). Coimmunoprecipitation showed that kindlin-1 can interact with Wnt10a. We showed that kindlin-1-mediated astrocyte activation was associated with Wnt10a/β-catenin signalling and the downstream release of inflammatory mediators in a CCI NP rat model. Our findings provide novel insights into the molecular mechanisms of kindlin-1-mediated astrocyte activation after CCI.

Abstract
Alzheimer disease (AD) is the most common type of dementia characterized by the progressive cognitive and social decline. Clinical drug targets have heavily focused on the amyloid hypothesis, with amyloid beta (Aβ), and tau proteins as key pathophysiologic markers of AD. However, no effective treatment has been developed so far, which prompts researchers to focus on other aspects of AD beyond Aβ, and tau proteins. Additionally, there is a mounting epidemiologic evidence that various environmental factors influence the development of dementia and that dementia etiology is likely heterogenous. In the past decades, new risk factors or potential etiologies have been widely studied. Here, we review several novel epidemiologic and clinical research developments that focus on sleep, hypoxia, diet, gut microbiota, and hearing impairment and their links to AD published in recent years. At the frontiers of AD research, these findings and updates could be worthy of further attention.

Abstract
Alzheimer's disease (AD) is considered as the most common cause of dementia in elderly population. While the exact mechanism of AD has not been discovered, hyperbolic oxygen therapy (HBOT) has been proven to be effective in the treatment of this degenerative disease. The objectives of this article are to review the literature available on molecular and physiological mechanisms underlying HBOT and its efficacy in treating AD and to review the effectiveness of HBOT as an alternate treatment intervention in both human and animal models. 391 full text articles were included in the review after literature search between 1980-2021 from two online data base (ScienceDirect and PubMed). The following key words were used: 'hyperbaric oxygen therapy' and 'Alzheimer disease.' Based on the outcomes of clinical and experimental studies, this review advocates the use of HBOT for the treatment of AD. This review explores future directions and recommends further research into a treatment protocol that will maintain long-term cognitive health of AD patients.

Abstract
Background: Neuronal apoptosis and inflammation in the ventral horn of the spinal cord contribute to denervated muscle atrophy post-burn. Hyperbaric oxygen therapy (HBOT) exerts anti-inflammation and neuroprotection. Furthermore, hypoxia-inducible factor (HIF)-1α has been reported to promote inflammation and apoptosis. We investigated the therapeutic potential of HBOT and the role of HIF-1α post-burn. Methods: Sprague-Dawley rats were divided into three groups: a control group, an untreated burn group receiving burn and sham treatment, and a HBOT group receiving burn injury and HBOT. The burn injury was induced with 75ºC ± 5ºC at the right hindpaw. HBOT (100% oxygen at 2.5 atmosphere, 90 min/day) and sham HBOT (21% oxygen at 1 atmosphere, 90 min/day) was started on day 28 after burn injury and continued for 14 treatments (days 28-41). Incapacitance (hind limb weight bearing) testing was conducted before burn and weekly after burn. At day 42 post-burn, the gastrocnemius muscle and the spinal cord ventral horn were analyzed. Results: HBOT improved burn-induced weight bearing imbalance. At day 42 post-burn, less gastrocnemius muscle atrophy and fibrosis were noted in the HBOT group than in the untreated burn group. In the ventral horn, HBOT attenuated the neuronal apoptosis and glial activation post-burn. The increases in phosphorylated AKT/mTOR post-burn were reduced after HBOT. HBOT also inhibited HIF-1α signaling, as determined by immunofluorescence and western blot. Conclusions: HBOT reduces burn-induced neuronal apoptosis in the ventral horn, possibly through HIF-1α signaling.

Abstract
Recent studies have shown that hyperbaric oxygen (HBO) has a therapeutic effect on
vascular dementia (VD); however, the exact mechanism remains unclear. This article aims to
reveal the protective effects and underlying mechanisms of HBO on VD. A total of 158
patients with VD were prospectively included in the study and were randomly divided into
control group and HBO group. The control group was given conventional treatment and the
HBO group was treated with HBO in addition to conventional treatment. The following HBO
protocol was practiced: 5 days per week, 60 min each, 100% oxygen at 2 standard
atmospheric pressures for 12 weeks. The Mini-Mental State Examination (MMSE) scores and
serum Humanin levels were detected before and after treatments in both groups. The
baseline characteristics were not different dramatically between groups
(p > 0.05). There was no significant difference in MMSE scores and
serum Humanin levels between the two groups before treatment (p >
0.05). After treatment, compared with the control group, the MMSE scores and serum Humanin
levels in the HBO group were significantly increased (p < 0.05).
Spearman correlation analysis showed that the serum Humanin levels were positively
correlated with MMSE scores (r = 0.409, p < 0.05) and
this correlation was independent of baseline characteristics (β = 0.312,
p < 0.05). HBO therapy can improve cognitive function in patients
with VD, and its mechanism may be related to elevated serum Humanin levels.

Abstract
Chronic hypoxia is considered as one of the important environmental factors contributing to the pathogenesis of Alzheimer's disease (AD). Many chronic hypoxia-causing comorbidities, such as obstructive sleep apnea syndrome (OSAS) and chronic obstructive pulmonary disease (COPD), have been reported to be closely associated with AD. Increasing evidence has documented that chronic hypoxia may affect many pathological aspects of AD including amyloid β (Aβ) metabolism, tau phosphorylation, autophagy, neuroinflammation, oxidative stress, endoplasmic reticulum (ER) stress, and mitochondrial and synaptic dysfunction, which may collectively result in neurodegeneration in the brain. In this Review, we briefly summarize the effects of chronic hypoxia on AD pathogenesis and discuss the underlying mechanisms. Since chronic hypoxia is common in the elderly and may contribute to the pathogenesis of AD, prospective prevention and treatment targeting hypoxia may be helpful to delay or alleviate AD.

Abstract
Hyperbaric oxygen (HBO2) became a mainstay for treating decompression sickness (DCS) because bubbles are associated with the disorder. Inflammatory processes including production of circulating microparticles (MPs) have now been shown to occur with DCS, leading to questions regarding pathophysiology and the role for HBO2. We investigated effects of HBO2 on mice exposed to 790 kPa air pressure for 2 h, which triggers elevations of MPs ladened with interleukin (IL)-1β that cause diffuse vascular injuries. Exposure to 283 kPa O2 (HBO2) inhibited MP elevations at 2 h postdecompression by 50% when applied either prophylactically or as treatment after decompression, and the MP number remained suppressed for 13 h in the prophylactic group. Particle content of IL-1β at 2 h postdecompression was 139.3 ± 16.2 [means ± SE; n = 11, P < 0.05) pg/million MPs vs. 8.2 ± 1.0 ( n = 15) in control mice, whereas it was 31.5 ± 6.1 ( n = 6, not significant vs. control (NS)] in mice exposed to HBO2 prophylactically, and 16.6 ± 6.3 ( n = 7, NS) when HBO2 was administered postdecompression. IL-1β content in MPs was similar in HBO2-exposed mice at 13 h postdecompression. HBO2 also inhibited decompression-associated neutrophil activation and diffuse vascular leak. Immunoprecipitation studies demonstrated that HBO2 inhibits high-pressure-mediated neutrophil nucleotide-binding domain, leucine-rich-containing family, pyrin domain-containing-3 inflammasome oligomerization. Furthermore, MPs isolated from decompressed mice cause vascular injuries when injected into naïve mice, but if decompressed mice were exposed to HBO2 before MP harvest, vascular injuries were inhibited. We conclude that HBO2 impedes high-pressure/decompression-mediated inflammatory events by inhibiting inflammasome formation and IL-1β production. NEW & NOTEWORTHY High pressure/decompression causes vascular damage because it stimulates production of microparticles that contain high concentrations of interleukin-1β, and hyperbaric oxygen can prevent injuries.

Galangin Inhibits Thrombin-Induced MMP-9 Expression in SK-N-SH Cells via Protein Kinase-Dependent NF-κB Phosphorylation. Int J Mol Sci 2018; 19:ijms19124084.

Abstract
Galangin, a member of the flavonol compounds of the flavonoids, could exert anti-inflammatory effects in various cell types. It has been used for the treatment of arthritis, airway inflammation, stroke, and cognitive impairment. Thrombin, one of the regulators of matrix metalloproteinase (MMPs), has been known as a vital factor of physiological and pathological processes, including cell migration, the blood–brain barrier breakdown, brain edema formation, neuroinflammation, and neuronal death. MMP-9 especially may contribute to neurodegenerative diseases. However, the effect of galangin in combating thrombin-induced MMP-9 expression is not well understood in neurons. Therefore, we attempted to explore the molecular mechanisms by which galangin inhibited MMP-9 expression and cell migration induced by thrombin in SK-N-SH cells (a human neuroblastoma cell line). Gelatin zymography, western blot, real-time PCR, and cell migration assay were used to elucidate the inhibitory effects of galangin on the thrmbin-mediated responses. The results showed that galangin markedly attenuated the thrombin-stimulated phosphorylation of proto-oncogene tyrosine-protein kinase (c-Src), proline-rich tyrosine kinase 2 (Pyk2), protein kinase C (PKC)α/β/δ, protein kinase B (Akt), mammalian target of rapamycin (mTOR), p42/p44 mitogen-activated protein kinase (MAPK), Jun amino-terminal kinases (JNK)1/2, p38 MAPK, forkhead box protein O1 (FoxO1), p65, and c-Jun and suppressed MMP-9 expression and cell migration in SK-N-SH cells. Our results concluded that galangin blocked the thrombin-induced MMP-9 expression in SK-N-SH cells via inhibiting c-Src, Pyk2, PKCα/βII/δ, Akt, mTOR, p42/p44 MAPK, JNK1/2, p38 MAPK, FoxO1, c-Jun, and p65 phosphorylation and ultimately attenuated cell migration. Therefore, galangin may be a potential candidate for the management of brain inflammatory diseases.

Abstract
Individuals with posttraumatic stress disorder (PTSD) are characterized by fear memory problems and hypocortisolemia of which traumatic stress-induced monoaminergic disruption over infralimbic (IL) cortex is considered the key mechanism. Hyperbaric oxygen therapy (HBOT) has recently proven its utility in treating several mental disorders but remains unexplored for PTSD. The present study aimed to examine the effects of 5-day HBO paradigm on traumatic stress (single prolonged stress, SPS, an animal model of PTSD)-induced dysregulation of fear memory/anxiety profiles and related abnormalities in IL monoamines and plasma corticosterone. Rats were randomly assigned to four groups (CON-sham, CON-HBOT, SPS-sham, and SPS-HBOT) and received Pavlovian fear conditioning test or elevated-T maze (ETM). The extracellular and tissue levels of monoamines over the IL cortex and the activity of the hypothalamus-pituitary-adrenal axis (i.e., the plasma corticosterone level and expression of the glucocorticoid receptor (GR) in the IL, hippocampus, amygdala, and hypothalamus) were measured. The results demonstrated that HBOT restored behaviorally the SPS-impaired fear extinction retrieval ability and SPS-induced conditioned anxiety, and neurochemically the SPS-reduced IL monoamines efflux level, and the corticosterone profiles. The present study shows some positive effects of HBOT in both behavioral and neurochemical profiles of PTSD outcomes.

Abstract
Recent studies indicate that hyperbaric oxygen therapy (HBOT), a well-established therapy for decompression illness, could be a potential therapy for Alzheimer's disease (AD). However, due to oxygen toxicity i.e., increased oxidative stress implicated in HBOT, the risk and benefit of HBOT for AD patients need to be further assessed clinically.

Abstract
Background Hyperbaric oxygen therapy is increasingly used in adjuvant therapies to treat neuropathic pain. However, the specific targets of hyperbaric oxygen treatment in neuropathic pain remain unclear. Recently, we found that hyperbaric oxygen therapy produces an antinociceptive response via the kindlin-1/wnt-10a signaling pathway in a chronic pain injury model in rats. Methods The rats received an intraperitoneal injection of AAV-FERMT1 or an adeno-associated virus control vector 20 days before the chronic constriction injury operation. During five consecutive days of hyperbaric oxygen treatment, mechanical withdrawal threshold and thermal withdrawal latency tests were performed. Then, kindlin-1 expression was examined by real-time polymerase chain reaction and Western blot analysis. Meanwhile, the activation of glial cells and the production of TNF-α, IL-1β, and fractalkine were also determined. Results Our findings demonstrated that hyperbaric oxygen therapy inhibited the chronic constriction injury–induced increase in kindlin-1 expression. Furthermore, overexpression of kindlin-1 reversed the antinociceptive effects of hyperbaric oxygen therapy. The observed hyperbaric oxygen–induced reductions in glial cell activation and neuroinflammation, as indicated by the production of TNF-α, IL-1β, and fractalkine, were also prominently diminished in the group with kindlin-1 overexpression. Conclusions Our findings demonstrate that kindlin-1 is a key protein in the action of hyperbaric oxygen therapy in the treatment of neuropathic pain. Indeed, interference with kindlin-1 may be a drug target for reducing the neuroinflammatory responses of the glial population in neuropathic pain.
