Ankyrin repeat and FYVE domain containing 1 (ANKFY1) is an indispensable protein in the development of cerebellar Purkinje cells. Our preliminary study revealed that its absence caused progressive spastic ataxia, accompanied by the loss of Purkinje cells in mice. Here, we generated Ankfy1-floxed (Ankfy1) mice, in which conditional inactivation of the Ankfy1 gene was achieved specifically in cerebellar Purkinje cells via crossing with a transgenic mouse strain expressing Cre recombinase under the regulatory control of the Purkinje cell protein 2 (PCP2) promoter.

Cross-linked polyethylene power cables are widely used in high-voltage DC transmission lines, owing to their good dielectric and physical-chemical properties. However, the production process of XLPE involves cross-linking and degassing, in which the cross-linking process produces a variety of cross-linking by-products, and the changes in the properties of the cable insulation caused by the degassing process are not well understood. XLPE samples were degassed at 90 °C for 7 and 14 days in this paper, and the main by-products were found to be α-methylstyrene, acetophenone, and cumyl alcohol, the contents of which all declined after the degassing treatment.

In order to develop efficient protocols for CO reduction with less expensive and more convenient hydrogen sources, the catalytic reactivities of group 10 metal hydride complexes supported by a PNCNP pincer ligand, [2,6-(BuPNH)CH]MH (M = Ni, ; Pd, ; Pt, ), against the hydroboration of CO with NH·BH and NaBH have been explored. Both and readily react with CO at room temperature to form the corresponding formato complexes, [2,6-(BuPNH)CH]MOC(O)H (M = Ni, ; Pd, ), in nearly quantitative yields.

Autosomal recessive spastic ataxia of Charlevoix-Saguenay (ARSACS) is a rare and early-onset neurodegenerative disease caused by variants of the SACS gene which maps to chromosome 13q11 and encodes sacsin protein. Sacsin is highly expressed in large motor neurons, in particular cerebellar Purkinje cells. This article has provided a review for the structure and function of sacsin protein and the mechanisms underlying abnormalities of sacsin in ARSACS disease.

The preparation of primary amines from nitriles has been a subject of continuing interest, and many different methods have been reported for this process. We report in this paper an alternative method for transforming nitriles into primary amines. In this work, a wide range of nitriles were reduced to primary amines by 1.

Epilepsy and migraine are among the most prevalent neurological disorders. By being comorbid, the presence of one disorder increases the likelihood of the other. Although several similar clinical features of epilepsy and migraine have been observed as early as the 19th century, only in recent years have researchers engaged in finding a common pathogenic mechanism between them.

A palladium(II) hydride complex supported by a benzene-based PNCNP pincer ligand, [2,6-(BuPNH)CH]PdH (1), has been synthesized two different routes: the reaction of the corresponding chloride complex with LiAlH and the reaction of the corresponding nitrate complex with KOCH. Complex 1 exhibits strong deprotonating ability and versatile catalytic activity. Acetamide can be readily deprotonated by complex 1 to form the corresponding acetamido complex, [2,6-(BuPNH)CH]PdNHC(O)CH, in high yield.

The coordination mode of the BH ligand in transition metal tetrahydroborate complexes is mainly dominated by the nature of the metal centres. However, other factors can also play important roles sometimes. In order to rationalize the coordination modes and the stability of the BH ligand in group 10 metal tetrahydroborate pincer complexes, [2,6-(BuPO)CH]Pt(η-HBH) and [CH--(NCHPBu)B]M(η-HBH) (M = Ni, Pt) were prepared and characterized.

The ageing characteristic of XLPE insulation of operating a 110 kV power cable with different service time is studied in this paper. The microscopic morphology of XLPE films from different cables were characterized by using Differential Scanning Calorimetry (DSC), X-ray Diffraction method (XRD), and Fourier Transform Infrared Spectroscopy (FTIR) methods, and the dielectric, mechanical, and electrical properties of XLPE were also measured. The relationship of several typical property parameters with the cable service time were established, and the ageing mechanism of XLPE insulation of the operating cable was also analyzed.

The nature and magnitude of nocebo responses in primary headache disorders are still unknown. To assess the distribution and possible predictors of nocebo responses in primary headache treatments, databases, including PubMed, EMBASE, and Cochrane Library were searched from 1988 to December 31, 2020, for parallel-group, double-blind, randomized placebo-controlled trials of pharmacologic treatments of primary headaches. The nocebo responses were calculated using a random effects meta-analysis model.

Spinocerebellar ataxia (SCA) is a group of autosomal dominant hereditary diseases. Based on their inheritance pattern, they can be divided into SCAs caused by expansion of microsatellite repeats or point mutations. Although SCAs may be diagnosed based on their clinical characteristics and results of genetic testing, their treatment still remains as a challenge.

The purpose of this study was to investigate the comfort of aircraft passengers during long flights and to determine the effects of the seatback angle and the seat pitch on passengers' upper body muscles (neck, shoulder, and lower back) and subjective comfort. All subjects sat on an aircraft seat for 2 h with different levels of seatback angle and seat pitch. Subjective discomfort scores and root mean square (RMS) and mean power frequency (MPF) values were used to evaluate muscle fatigue, and all data were calculated for every 15-min interval.

Congenital muscular dystrophy with laminin-α2 deficiency, also known as MDC1A, displays an extensive phenotypic and genetic heterogeneity. The combination of clinical, biochemical, and genetic findings must be considered to obtain the precise diagnosis and provide appropriate genetic counseling. Here we report one individual from a family presenting with clinical features including seizure attack, slight weakness of proximal leg muscles, and mild cognitive impairment with increased small angular fibers, decreased expression of α-DG and β-DG, normal expression of laminin-α2, and severe white matter changes.

The existing data about whether acid sensing ion channels (ASICs) are proconvulsant or anticonvulsant are controversial. Particularly, acid sensing ion channel 3 (ASIC3) is the most sensitive to extracellular pH and has the characteristic ability to generate a biphasic current, but few studies have focused on the role of ASIC3 in seizure. Here we found ASIC3 expression was increased in the hippocampus of pilocarpine induced seizure rats, as well as in hippocampal neuronal cultures undergoing epileptiform discharge elicited by Mg-free media.

Article Synopsis
  • The study investigates Guillain-Barré syndrome (GBS) subtypes and their clinical features in southern China, focusing on comparisons between demyelinating (AIDP) and axonal forms (AMAN), particularly how infections and age impact severity.
  • A retrospective review of 1,056 patients' medical records from 31 hospitals between 2013 to 2016 reveals that AIDP is the most common subtype, while AMAN tends to present more severely and with distinct preceding infections.
  • Findings suggest that prior respiratory infections are linked to AIDP, while gastrointestinal infections correlate with more severe AMAN cases; age also influences disease severity and recovery, with children and the elderly being affected more severely.
