A retrospective review of sex differences of white matter hyperintensities in brain MRI of patients with migraine
CONCLUSION: This study suggests that females with migraine may be more likely to have WMHs and experience constipation than males with migraine. Migraine frequency and severity were not different between sexes, nor were they significantly associated with the presence of WMHs. The findings of this study do not support a specific etiology of WMH development in individuals with migraine that differs from findings in the general population. Further studies are warranted.PMID:38785411 | DOI:10.1111/head.14714 (Source: Headache)

Dysregulated expression of cholesterol biosynthetic genes in Alzheimer's disease alters epigenomic signatures of hippocampal neurons
Neurobiol Dis. 2024 May 22:106538. doi: 10.1016/j.nbd.2024.106538. Online ahead of print.ABSTRACTAging is the main risk factor of cognitive neurodegenerative diseases such as Alzheimer's disease, with epigenome alterations as a contributing factor. Here, we compared transcriptomic/epigenomic changes in the hippocampus, modified by aging and by tauopathy, an AD-related feature. We show that the cholesterol biosynthesis pathway is severely impaired in hippocampal neurons of tauopathic but not of aged mice pointing to vulnerability of these neurons in the disease. At the epigenomic level, histone hyperacetylation was observed...

MRI-derived brain iron, grey matter volume, and risk of dementia and Parkinson's disease: Observational and genetic analysis in the UK Biobank cohort
Neurobiol Dis. 2024 May 22:106539. doi: 10.1016/j.nbd.2024.106539. Online ahead of print.ABSTRACTBACKGROUND: Iron overload is observed in neurodegenerative diseases, especially Alzheimer's disease (AD) and Parkinson's disease (PD). Homozygotes for the iron-overload (haemochromatosis) causing HFE p.C282Y variant have increased risk of dementia and PD. Whether brain iron deposition is causal or secondary to the neurodegenerative processes in the general population is unclear.METHODS: We analysed 39,533 UK Biobank participants of European genetic ancestry with brain MRI data. We studied brain iron estimated by R2* and quantit...

rdHSV-CA8 non-opioid analgesic gene therapy decreases somatosensory neuronal excitability by activating Kv7 voltage-gated potassium channels
This study tested the hypothesis that novel JDNI8 replication-defective herpes simplex-1 viral vectors (rdHSV) carrying a CA8 transgene (vHCA8) reduce primary afferent neuronal excitability. Whole-cell current clamp recordings in small DRG neurons showed that vHCA8 transduction caused prolongation of their afterhyperpolarization (AHP), an essential regulator of neuronal excitability. This AHP prolongation was completely reversed by the specific Kv7 channel inhibitor XE-991. Voltage clamp recordings indicate an effect via Kv7 channels in vHCA8-infected small DRG neurons. These data demonstrate for the first time that vHCA8 ...

New technology to address affected vs nonaffected arm contributions to ergometer performance in people poststroke
CONCLUSIONS: Poststroke participants pedaled faster with their affected arm unilaterally versus bilateral pedaling, suggesting interhemispheric interference that reduces the ability to recruit the paretic arm during bilateral exercise.PMID:38785263 | DOI:10.1080/10749357.2024.2356415 (Source: Topics in Stroke Rehabilitation)

PTEN inhibition promotes robust growth of bulbospinal respiratory axons and partial recovery of diaphragm function in a chronic model of cervical contusion spinal cord injury
In conclusion, we find that, when PTEN inhibition is targeted at a chronic time point following cervical contusion, our non-invasive PAP4 strategy can successfully promote significant regrowth of damaged respiratory neural circuitry and also partial recovery of diaphragm motor function.PMID:38789023 | DOI:10.1016/j.expneurol.2024.114816 (Source: Experimental Neurology)

Japanese medaka (Oryzias latipes) Nectin4 plays an important role against red spotted grouper nervous necrosis virus infection
In this study, nectin4 gene was cloned from medaka (OlNectin4). OlNectin4 was located on chromosome 18 and contained 11 exons, with a total genome length of 25754 bp, coding sequences of 1689 bp, coding 562 amino acids and a molecular weight of 65.5 kDa. OlNectin4 contained four regions, including an Immunoglobulin region, an Immunoglobulin C-2 Type region, a Transmembrane region and a Coiled coil region. OlNectin4 shared 47.18% and 25.00% identity to Paralichthys olivaceus and Mus musculus, respectively. In adult medaka, the transcript of nectin4 was predominantly detected in gill. During red spotted grouper nervous necro...

Neonatal resveratrol treatment in cerebral palsy model recovers neurodevelopment impairments by restoring the skeletal muscle morphology and decreases microglial activation in the cerebellum
This study aimed to investigate the effects of neonatal resveratrol treatment on neurodevelopment, skeletal muscle morphology, and cerebellar damage in CP model. Wistar rat pups were allocated to four experimental groups (n = 15/group) according CP model and treatment: Control+Saline (CS), Control+Resveratrol (CR), CP + Saline (CPS), and CP + Resveratrol (CPR). CP model associated anoxia and sensorimotor restriction. CP group showed delay in the disappearance of the palmar grasp reflex (p < 0.0001) and delay in the appearance of reflexes of negative geotaxis (p = 0.01), and free-fall righting (p < 0.0001), reduced lo...

Establishment of a novel cellular model for Alzheimer's disease in vitro studies
CONCLUSION: We can infer that the MEK1/2-ERK and NF-κβ pathways, respectively, are directly activated by the PAF C-16 and BetA chemicals. The activation of MEK1/2-ERK pathway results in the activation of the APP gene, which in turn activates the β. Amyloid protein, which in turn results in plaque. Furthermore, NF-κβ activation results in the activation of the MAPT gene, which leads to Tau and p-Tau protein activation, which ultimately results in tangles. This can be put into practice in just three days, with a high level of activity and stability that is passed down to the next three generations (subculture), with sig...
