Type 2 immune cells play a pivotal role in allergic rhinitis (AR). Increasing evidence shows that inhibition of cholinergic nerve activity decreases the severity of airway diseases including asthma and AR. However, the role of the cholinergic receptor muscarinic 3 (m3) in type 2 inflammation in AR is unknown.

We aimed to investigate the effect of m3 on the type 2 immune response, including both T helper 2 (Th2)-mediated and type 2 innate lymphocyte (ILC2)-mediated inflammation, in AR.

Peripheral blood mononuclear cells (PBMCs) from human were cultured in vitro. Treatment with the m3 antagonist 1,1-dimethyl-4-diphenylacetoxypiperidinium iodide (4-DAMP) was used. The percentages of Th2 and ILC2 cells in PBMCs were evaluated by flow cytometry. AR mouse models were established by house dust mite (HDM) sensitization, and treated with tiotropium intranasally. The expression of Th2 cytokines, ILC2 cytokines and related factors in the nasal mucosa was assessed by immunohistochemistry and quantitative real-time polymerase chain reaction. Serum HDM-specific immunoglobulin E (sIgE) level was detected by enzyme-linked immunosorbent assay.

Both Th2 and ILC2 percentages in PBMCs were decreased after 4-DAMP treatment. Similarly, the levels of Th2 cytokines (interleukin 4 [IL-4] and IL-13) and ILC2 cytokines and related factors (IL-25, IL-33, GATA3 and RORα) were significantly decreased in the nasal mucosa of AR mice after tiotropium treatment. Furthermore, tiotropium treatment decreased the nasal symptom score, the serum sIgE level and eosinophil infiltration in AR mice. In addition, tiotropium decreased phospholipase Cγ1 (PLCγ1), PLCγ2, nuclear factor of activated T cell 1 (NFATc1), and NFATc2 mRNA levels in AR mice.

Antagonism of m3 alleviated type 2 inflammation in the nasal mucosa of AR mice.

The incidence of AMD increases with age. Retinal pigment epithelial (RPE) cells maintain retinal homeostasis and support the functionality of photoreceptors. In the pathogenesis of AMD, the degeneration of the RPE cells precedes photoreceptor cell death. RPE cells are susceptible to oxidative stress, and chronic inflammation involving nucleotide-binding domain, leucine-rich repeat and pyrin domain 3 (NLRP3) inflammasome activation and impaired autophagy are challenges faced by aged RPE cells in AMD. There are two types of AMD, dry (85-90%) and wet (10-15%) disease forms. Choroidal neovascularization is typical for wet AMD, and anti-vascular endothelial growth factor (anti-VEGF) injections are used to prevent the progression of the disease but there is no curative treatment. There is no cure for the dry disease form, but antioxidants have been proposed as a potential treatment option. Ageing is thets.The sleep cycle alternates between REM and NREM sleep, but the mechanisms by which this cycle is generated are totally unknown. We found that a periodic transient increase of the dopamine level in the amygdala during NREM sleep terminates NREM sleep and initiates REM sleep. This mechanism also plays a role in cataplectic attack, which is a pathological intrusion of REM sleep into wakefulness in narcoleptics.Electroencephalography (EEG) and magnetoencephalography (MEG) are the only noninvasive imaging methods of human brain function with temporal resolutions of millisecond-order. MEG has theoretically superior spatial resolution to EEG. However, the weak signal of MEG can only be measured with the superconducting quantum interference device (SQUID). SQUID-MEG equipment has extremely high manufacture and running costs. Moreover, the theoretically high spatial resolution is practically limited by the necessary setback distances between the sensors and scalp, because the Dewar vessel containing liquid helium for the SQUIDs requires a thick vacuum wall. MAPK inhibitor The latest developments in room temperature magnetometers, such as tunnel magnetic resistance (TMR) sensors, may solve the problem of setback distance in MEG scanners. Here I review my personal research history of MEG from the era of single-channel SQUID-MEG to the present era of single-channel TMR-MEG. I also propose the major considerations for the future development of MEG systems.Cerebellar ataxia with neuropathy and vestibular areflexia syndrome (CANVAS) is characterized by the triad of cerebellar ataxia, bilateral vestibular impairment, and sensory neuropathy. The responsible anatomical region for the sensory disturbance in CANVAS is reportedly the dorsal root ganglion, which suggests neuronopathy rather than neuropathy as the pathomechanism of this peripheral nervous system disorder. Early on, motor neuron involvement was considered rare in CANVAS. The etiology of CANVAS includes the homozygous pentanucleotide repeat expansion within the RFC1 gene, resulting in diverse phenotypes and motor deficits such as brisk reflex, extensor plantar responses, or spasticity of the upper motor neurons and muscle wasting, weakness, cramp, or fasciculation of the lower motor neurons. CANVAS patients with AAGGG repeat expansions may show motor neuron involvement, with considerable variation in the reported frequencies. In contrast, although some patients with ACAGG repeat expansions also show motor neuron involvement, its frequency remains elusive.Recently, the biallelic expansion of an AAGGG repeat in RFC1 was reported as a cause of cerebellar ataxia with neuropathy and vestibular areflexia syndrome. This mutation has also been reported in more selected nervous disorders, including pure sensory axonal polyneuropathy. Thus, the multisystem disorders caused by this mutation are now considered RFC1-related spectrum disorders. Here, we review the previous reports about RFC1-related spectrum disorders from the aspect of neuropathy.Replication factor C subunit 1 (RFC1) spectrum disorders are characterized by a variety of symptoms, including cerebellar ataxia, sensory neuropathy, and vestibular dysfunction, which may occur singularly or in various combinations. RFC1 spectrum disorders may mimic the clinical manifestations and imaging findings of multiple system atrophy. We describe the prevalence, genetic features, and imaging findings of RFC1 spectrum disorders.Among patients with RFC1 spectrum disorders represented by the phenotype of cerebellar ataxia with neuropathy and vestibular areflexia syndrome (CANVAS), at least 60% are known to manifest chronic, paroxysmal, and spasmodic dry cough. Chronic cough is a key diagnostic feature of RFC1-related diseases. It is often the first symptom and, in some cases, precedes neurological symptoms such as ataxia and sensory disturbance for more than 30 years. Although the pathogenesis of the cough remains unclear, it is possible that impairment of the vagus nerve, which includes an afferent pathway of the cough reflex, or the cerebellum would have contributed to the generation of the cough.More than 90% of replication factor c subunit 1 (RFC1) gene-related spectrum disorders such as cerebellar ataxia with neuropathy and vestibular areflexia syndrome (CANVAS) have bilateral vestibular dysfunction. A case with CANVAS presented in this paper showed repeat extension of AAGGG in the intron region of the RFC1 gene, and showed bilateral vestibular dysfunction in caloric test, vestibular evoked myogenic potential, video Head Impulse Test and rotary chair test. Visual enhanced vestibulo-ocular reflex tests also revealed abnormalities, suggesting the presence of combined lesions of the cerebellum and brainstem including vestibular nuclei.Cerebellar ataxia with neuropathy and vestibular areflexia syndrome (CANVAS) is characterized by neuropathological changes such as loss of Purkinje cells and degeneration of the posterior column of the spinal cord. In the peripheral nervous system, CANVAS is associated with loss of ganglion cells in the dorsal root and vestibular ganglia. Some patients may show degeneration of the inferior olivary nucleus, corticospinal tracts, and the facial and trigeminal ganglia. Further research is warranted to determine whether differences in lesion distribution are attributable to differences in genetic abnormalities and their combinations. To date, aggregates of abnormal proteins such as intranuclear inclusion bodies characteristic of this disease have not been identified in the nervous system.Biallelic intronic repeat expansion in the RFC1 gene was reported as a cause of cerebellar ataxia with neuropathy and vestibular areflexia syndrome (CANVAS). Its clinical features include late-onset cerebellar ataxia, sensory neuropathy (or neuronopathy), bilateral vestibular impairment, autonomic dysfunction, chronic cough, pyramidal sign, or parkinsonism. Repeat conformations heterogeneity is observed along with the possible phenotype-genotype correlation while its molecular pathogenesis remains uncovered.Cerebellar ataxia with neuropathy and vestibular areflexia syndrome (CANVAS) refers to a multi-system neurodegenerative disorder, with middle-age onset, which mainly presents with progressive imbalance. Imbalance is attributable to isolated or combined impairment of the cerebellar, proprioceptive, and vestibular systems. Chronic spasmodic cough, which usually precedes neurological symptoms, serves as a useful diagnostic clue to CANVAS. Diagnostic criteria have been proposed for CANVAS in 2016, based on 3 cardinal features. In 2019, a biallelic intronic AAGGG repeat expansion (AAGGG)exp in the replication factor complex subunit 1 gene (RFC1) was identified as a genetic contributor to CANVAS, and (ACGGG)exp in RFC1 was subsequently confirmed as a causative factor for CANVAS. Genetic screening for RFC1 has shown that CANVAS is an overlooked entity in patients with cerebellar ataxia or sensory neuropathy, which highlights more restricted phenotypes that exclusively involve one of the aforementioned systems. The phenotypic spectrum of RFC1-related disorders has been expanding since the discovery of (AAGGG)exp or (ACGGG)exp in the RFC1. Studies have reported atypical features, including parkinsonism, motor neuron involvement, cognitive decline, and sleep disorders. Currently, a wide variety of clinical conditions associated with biallelic intronic pentanucleotide repeat expansion in RFC1 are classified as RFC1 CANVAS/spectrum disorder.
Traditionally, simultaneous liver kidney transplantation (SLK) has been performed using a subcostal incision for the liver allograft and a lower abdominal incision for kidney transplantation (dual incision, DI). At our institution, we performed SLK using a single subcostal incision (SI). The aim of this study was to report the outcomes of single versus dual incisions for SLK.

A retrospective cohort study of consecutive SLK procedures performed at our center from January 2015 to April 2021 was performed. The demographic characteristics, complications, intraoperative findings, and complications after SI and DI were statistically compared.

A total 37 SLK were performed (19 DI and 18 SI). The age and indications for transplantation were comparable between the two groups. Patient in SI group had significantly higher MELD score (27.0±1.5vs. 31.7±1.5, p=.038). The cold ischemic time of kidney transplantation (599±26min vs. 447±27min, p<.001) and the total surgical time (508±21min vs. 423±22min, p=.008) were significantly shorter in the SI group.
