The objective of this study was to investigate the use of ultrasound to guide puncture in the normal coronal brain structure and determine the puncture depth of the location of the cortex, hippocampus, lateral ventricle, and striatum of newborn rats of 5−15 days. The animal was placed in a prone position. The specific positions of the cortex, hippocampus, lateral ventricle, and striatum were measured under ultrasound. Then, the rats were punctured with a stereotaxic instrument, and dye was injected. Finally, the brains of rats were taken to make frozen sections to observe the puncture results. By ultrasound, the image of the cortex, hippocampus, lateral ventricle, and striatum of the rat can be obtained and the puncture depth of the cortex (8 days: 1.02 ± 0.12, 10 days: 1.02 ± 0.08, 13 days: 1.43 ± 0.05), hippocampus (8 days: 2.63 ± 0.07, 10 days: 2.77 ± 0.14, 13 days: 2.82 ± 0.09), lateral ventricle (8 days: 2.08 ± 0.04, 10 days: 2.26 ± 0.03, 13 days: 2.40 ± 0.06), and corpus striatum (8 days: 4.57 ± 0.09, 10 days: 4.94 ± 0.31, 13 days: 5.13 ± 0.10) can be accurately measured. The rat brain structure and puncture depth changed with the age of the rats. Ultrasound technology can not only clarify the brain structure characteristics of 5—15-day-old rats but also guide the puncture and injection of the rat brain structure. The results of this study laid the foundation for the future use of ultrasound in experimental animal models of neurological diseases.","PeriodicalId":94030,"journal":{"name":"Ibrain","volume":"9 4","pages":"359-368"},"PeriodicalIF":0.0,"publicationDate":"2023-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ibra.12103","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83526379","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The cranial magnetic resonance imaging revealed changes in bilateral frontal lobe ischemic foci, bilateral frontal, ethmoid, sphenoid and maxillary sinusitis, and retinal macular degeneration. After hormone shock treatment, the condition improved. He suffered from headaches again with blurred vision in the right eye 7 months ago and was initially diagnosed with multiple sclerosis. He then was discharged after improvement due to hormone shock therapy. Oral hormone therapy was continued outside the hospital, but he stopped it due to drug side effects (details remained unclear). After cutting off, he developed a headache and visited our hospital once more, the relevant tests were performed and the patient was diagnosed with idiopathic hypertrophic pachymeningitis (IHP). The symptoms were slightly abated after hormone therapy.

Over the years, animal models of HIE have been a research hotspot to find ways to cope with HIE and thereby reduce the risk of neonatal death or disability in moderate-to-severe HIE. By reviewing the literature related to HIE over the years, it was found that nonhuman primates share a high degree of homology with human gross neural anatomy. The basic data on nonhuman primates are not yet complete, so it is urgent to mine and develop new nonhuman primate model data. In recent years, the research on nonhuman primate HIE models has been gradually enriched and the content is more novel. Therefore, the purpose of this review is to further summarize the methods for establishing the nonhuman primate HIE model and to better elucidate the relevance of the nonhuman primate model to humans by observing the behavioral manifestations, neuropathology, and a series of biomarkers of HIE in primates HIE. Finally, the most popular and desirable treatments studied in nonhuman primate models in the past 5 years are summarized.","PeriodicalId":94030,"journal":{"name":"Ibrain","volume":"9 2","pages":"183-194"},"PeriodicalIF":0.0,"publicationDate":"2023-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ibra.12097","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41124635","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing clinical trials mainly include middle-aged and elderly patients with stroke or Parkinson's disease (mostly 40–80 years old), mainly involving injection of mesenchymal stem cells and bone marrow mesenchymal stem cells through the veins and the putamen, with a dosage of mostly 106–108 cells.

MDD is a chronic mental illness that affects 300 million people across the world. Clinical manifestations of MDD include fatigue, loss of interest in routine tasks, psychomotor agitation, impaired ability to focus, suicidal ideation, hypersomnolence, altered psychosocial functioning, and appetite loss. Individuals with depression also demonstrate a reduced behavioral response while experiencing pleasure, a symptom known as anhedonia. Like MDD, PTSD is a prevalent and debilitating psychiatric disorder resulting from a traumatic incident such as sexual assault, war, severe accident, or natural disaster. Symptoms such as recalling event phases, hypervigilance, irritability, and anhedonia are common in PTSD. Both MDD and PTSD pose enormous socioeconomic burdens across the globe. The search for effective treatment with minimal side effects is still ongoing. Ketamine is known for its anesthetic and analgesic properties. Psychedelic and psychotropic effects of ketamine have been found on the nervous system, which highlights its toxicity.

The Zea–Longa score was used to evaluate the neurological function of the rats. ImageJ was used for quantification of the brain edema volume. Triphenyl tetrazolium chloride (TTC) staining of brain tissue was performed 24 h after hypoxic–ischemic (HI) to detect right brain infarction. The expression of TNF-α was detected by real-time quantitative polymerase chain reaction (RT-qPCR). Immunofluorescence staining was used to identify the localization of TNF-α; Then, the effective shRNA fragment of TNF-α was used to validate the role of TNF-α in HIE rats, and the change of neurotrofin-3 (NT-3) and tyrosine kinase receptor-C (TRKC) was examined after TNF-α-shRNA lentivirus transfection to determine downstream signaling associated with TNF-α. Protein interaction analysis was carried out to predict the links among TNF-α, NT-3, and TRKC. Cerebral edema volume and infarction increased in the right brain after the HI operation. The Zea–Longa score significantly increased within 24 h after the HI operation. The relative expression of TNF-α was upregulated after the HI operation. TNF-α was highly expressed in the right hippocampus post HI through immunofluorescence staining. Bioinformatics analysis found a direct or an indirect link among TNF-α, NT-3, and TRKC. Moreover, the interference of TNF-α increased the expression of NT-3 and TRKC.

The efficacy of the compounds was determined by behavioral experiments using the Y-maze and the Barnes maze and neurochemical testing. Both compounds reduced the effect of scopolamine treatment in the behavioral tasks at a dose of 20 mg/kg. The results of the neurochemical experiment indicated a reduction in cholinesterase activity in the prefrontal cortex and the hippocampus. The levels of antioxidant enzymes superoxide dismutase and catalase were restored compared to the scopolamine-treated groups. The docking study on rat butyrylcholinesterase (BChE) indicated tight binding, with free energies of −9.66 and −10.23 kcal/mol for compounds 30 and 33, respectively. The two aromatic amide derivatives of 2-phenyl-2-(phenylsulfonamido) acetic acid produced stable complexes with rat BChE in the molecular dynamics investigation.","PeriodicalId":94030,"journal":{"name":"Ibrain","volume":"9 1","pages":"13-31"},"PeriodicalIF":0.0,"publicationDate":"2023-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ibra.12092","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50150659","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
