Abstract
INTRODUCTION Variants in the GNB1 gene, which encodes the β1 subunit of a trimeric G protein, can cause moderate to severe psychomotor retardation. Acute encephalopathies have also been observed in patients with central nervous system abnormalities; however, severe neurological sequelae have not previously been reported. CASE PRESENTATIONS Patient 1 was a Japanese female with a de novo GNB1 variant (c.284 T > C). At 8 months old she contracted influenza A and developed generalized convulsions. In the acute phase, brain magnetic resonance imaging (MRI) findings indicated acute encephalopathy; diffuse cerebral atrophy was present 1 month later. Although multidisciplinary treatment was administered, she had severe neurological sequelae including spastic tetraplegia, severe intellectual disabilities, and refractory epilepsy. Patient 2 was a Japanese male with a de novo GNB1 variant (c.239 T > C). He experienced an unexplained respiratory arrest aged 17 years; refractory convulsions developed. Brain MRI at 1 month showed bilateral basal ganglia high intensities; at 3 months, diffuse cerebral cortex and white matter atrophy was observed. Despite multidisciplinary treatment, he developed severe spastic tetraplegia and mental regression. DISCUSSION We report two patients with GNB1 variants who had acute lesions on brain MRI and unexpected disease courses. In such patients with acute neurological deterioration, multidisciplinary treatment is required; patients should also be carefully observed for progression to acute encephalopathy.

Abstract
Under magnetic fields, quantum magnets often undergo exotic phase transitions with various kinds of order. The discovery of a sequence of fractional magnetization plateaus in the Shastry-Sutherland compound SrCu2(BO3)2 has played a central role in the high-field research on quantum materials, but so far this system could only be probed up to half the saturation value of the magnetization. Here, we report the first experimental and theoretical investigation of this compound up to the saturation magnetic field of 140 T and beyond. Using ultrasound and magnetostriction techniques combined with extensive tensor-network calculations (iPEPS), several spin-supersolid phases are revealed between the 1/2 plateau and saturation (1/1 plateau). Quite remarkably, the sound velocity of the 1/2 plateau exhibits a drastic decrease of -50%, related to the tetragonal-to-orthorhombic instability of the checkerboard-type magnon crystal. The unveiled nature of this paradigmatic quantum system is a new milestone for exploring exotic quantum states of matter emerging in extreme conditions.

Abstract
Background and purpose Hereditary spastic paraplegias (HSPs) are a set of heterogeneous neurodegenerative disorders characterized by bilateral lower limb spasticity. They may present from infancy onwards at any time. Although next-generation sequencing has allowed the identification of many causative genes, little is known about which genes are specifically associated with pediatric-onset variants. Methods This study retrospectively evaluated the genetic analyses, family history clinical courses, magnetic resonance imaging (MRI) findings, and electrophysiologic findings of patients diagnosed with HSP in childhood at a tertiary pediatric hospital in Japan. Genetic analyses were performed using direct sequencing, disease-associated panels, and whole-exome sequencing. Results Of the 37 patients included, 14 had a family history of HSP and 23 had a sporadic form of the disease. In 20 patients, HSP was the pure type, whereas the remaining 17 patients had complex types of HSP. Genetic data were available for 11 of the pure-type patients and 16 of those with complex types. Of these, genetic diagnoses were possible in 5 (45%) of the pure-type and 13 (81%) of the complex-type patients. SPAST variants were found in five children, KIF1A variants in four, ALS2 variants in three, SACS and L1CAM variants in two each, and an ATL1 variant in one. One child had a 10p15.3p13 duplication. Four patients with pure-type HSPs had SPAST variants and one had an ALT1 variant. The KIF1A, ALS2, SACS, and L1CAM variants and the 10p15.3p13 duplication were seen in children with complex-type HSPs, with just one complex-type patient having a SPAST variant. The identification of brain abnormalities on MRI was significantly more common among children with complex-type (11 [69%] of 16) than pure-type HSPs (one [5%] of 19) (p < 0.001). Scores on the modified Rankin Scale for Neurologic Disability were also significantly higher among children with complex-type compared with pure-type HSPs (3.5 ± 1.0 vs. 2.1 ± 0.9, p < 0.001). Conclusion Pediatric-onset HSP was found to be sporadic and genetic in a substantial proportion of patients. The causative gene patterns differed between children with pure-type and complex-type HSPs. The causative roles of SPAST and KIF1A variants in pure-type and complex-type HSPs, respectively, should be explored further.

Abstract
BACKGROUND Malignant hyperthermia is an extremely dangerous condition that can occur with exposure to volatile inhalant anesthetics and depolarizing muscle relaxants, and that requires immediate intervention. Neurological complications have rarely been reported, with no reports of electroencephalographic abnormalities or encephalopathy. Here, we report a case of severe electroencephalographic abnormality in the acute phase of malignant hyperthermia that eventually led to diffuse cerebral cortical damage. CASE PRESENTATION A 15-month-old Japanese boy underwent a Rastelli procedure to correct a double-outlet right ventricle and pulmonary atresia. Sevoflurane was used for induction and maintenance of anesthesia during surgery. After withdrawal from the heart-lung machine, his body temperature rose at a rate of 0.1 ℃/minute, and when he left the operating room, his core body temperature had reached 42 ℃. After admission to the intensive care unit, tachycardia, high PaCO2, and progressive metabolic acidosis were observed. A clinical grading scale score of 63 indicated malignant hyperthermia, and dantrolene was administered. The pupils were dilated, and the electroencephalogram showed persistent generalized continuous multifocal spikes. Midazolam, levetiracetam, and fosphenytoin were administered without improvement, and thiamylal and ketamine were infused continuously. After the electroencephalogram shifted to burst suppression, the epileptic firing gradually decreased, and the background electroencephalogram became lower in amplitude. Magnetic resonance imaging of the head performed after the patient was hemodynamically stable suggested diffuse cerebral cortical damage. Severe mental retardation, hypertonia, and quadriplegia were observed as neurological complications. CONCLUSIONS In this case, despite the use of high-dose anticonvulsants, the patient showed severe electroencephalogram abnormality, resulting in diffuse cortical damage. Hyperthermia is known to damage the central nervous system by causing increased brain pressure and cerebral edema, which may have triggered the severe neuronal excitation that we observed in this case. The presence of systemic inflammatory response syndrome and the patient's background, including young age and ethnicity, might also have been factors. Malignant hyperthermia can be complicated by encephalopathy, and continuous electroencephalogram monitoring should be considered.

Abstract
Say-Barber-Biesecker-Young-Simpson syndrome (SBBYSS) and genitopatellar syndrome (GPS) are caused by variants of lysine acetyltransferase 6B (KAT6B). These variants tend to occur in the terminal exons of KAT6B. Here, we report a patient with global developmental delay, intellectual disability, autistic behavior, muscular hypotonia, facial dysmorphism, and seizures caused by a novel missense variant in exon 7 of KAT6B. The patient showed a phenotype differing from those of SBBYSS and GPS. We also report patients with missense variants in the proximal exons of KAT6B showing dysmorphic features and autistic behavior not resembling the characteristics of SBBYSS and GPS. Missense variants in the proximal exons of KAT6B may have a dominant negative effect or cause gain of function, leading to unique phenotypes not resembling those of SBBYSS and GPS.

Abstract
BACKGROUND There is growing interest in examining objective markers for early identification and behavioral intervention to prevent dementia and mild cognitive impairment in clinical and community settings. OBJECTIVE To investigate the association between salivary alpha-amylase as an objective measure of psychological stress response and mild cognitive impairment for the implication of psychological stress in the development of mild cognitive impairment. DESIGN, SETTING, AND PARTICIPANTS This cross-sectional study involved 865 participants aged ≥ 65 years. A saliva sample was collected in the morning, and the levels of salivary alpha-amylase were assayed. Mild cognitive impairment was evaluated using the Japanese version of the Montreal Cognitive Assessment; a score < 26 was indicative of mild cognitive impairment. A multivariable logistic regression model was used to examine the association of salivary alpha-amylase and mild cognitive impairment after adjusting for age, sex, current drinking status, current smoking status, body mass index, hypertension, diabetes mellitus, physical activity, education, social support, social network, and heart rate variability. RESULTS Salivary alpha-amylase was associated with mild cognitive impairment (the multivariable-adjusted odds ratio [95% confidence interval] for the 1-standard deviation increment of log-transformed salivary alpha-amylase was 1.24 [1.07-1.44]). This significant association persisted after adjusting for various confounding factors. CONCLUSION Elevation of salivary alpha-amylase was associated with mild cognitive impairment among Japanese community-dwelling older adults. This suggests that salivary alpha-amylase is a useful objective marker of psychological stress responses associated with mild cognitive impairment.

Abstract
Magnetoresistance of the correlated narrow-gap semiconductor FeSi was investigated by the radio frequency self-resonant spiral coil technique in magnetic fields up to 500 T, which is supplied by an electromagnetic flux compression megagauss generator. Semiconductor-to-metal transition accomplishes around 270 T observed as a sharp kink in the magnetoresistance, which implies the closing of the hybridization gap by the Zeeman shift of band edges. In the temperature-magnetic field phase diagram, the semiconductor-metal transition field is found to be almost independent of temperature, which is in contrast to a characteristic magnetic field associated with the hopping magnetoconduction in the in-gap localized states, exhibiting a notable temperature dependence.

Abstract
Single-turn coil (STC) technique is a convenient way to generate ultrahigh magnetic fields of more than 100 T. During the field generation, the STC explosively destructs outward due to the Maxwell stress and Joule heating. Unfortunately, the STC does not work at its full potential because it has already expanded when the maximum magnetic field is reached. Here, we propose an easy way to delay the expansion and increase the maximum field by using a mass-loaded STC. By loading clay on the STC, the field profile drastically changes, and the maximum field increases by 4%. This method offers access to higher magnetic fields for physical property measurements.

Abstract
BACKGROUND Marked decreases in serum creatine kinase levels have been noted in Duchenne and Becker muscular dystrophies as rare complications of autoimmune or autoinflammatory diseases. SUBJECTS AND METHODS The influence of systemic inflammation on serum creatine kinase levels was reviewed from the charts of three subjects with Fukuyama congenital muscular dystrophy. RESULTS A total of 30 infectious events were identified. Elevated serum C-reactive protein levels coincided with decreased creatine kinase levels on 19 occasions. In one subject, administration of 2 mg/kg/d prednisolone for bronchial asthma resulted in a decrease in creatine kinase level on six other occasions. CONCLUSION Apart from an increase in endogenous cortisol secretion, certain inflammation-related molecules could play a role in mitigating muscle cell damage in Fukuyama congenital muscular dystrophy during febrile infectious episodes. Corticosteroids may be a promising agent for the treatment of muscular symptoms in this disorder.

Abstract
The entire magnetization process of TlCuCl_{3} has been experimentally investigated up to 100 T employing the single-turn technique. The upper critical field H_{c2} is observed to be 86.1 T at 2 K. A convex slope of the M-H curve between the lower and upper critical fields (H_{c1} and H_{c2}) is clearly observed, which indicates that a particle-hole symmetry is broken in TlCuCl_{3}. By quantum Monte Carlo simulation and the bond-operator theory method, we find that the particle-hole symmetry breaking results from strong interdimer interactions.

Abstract
Salivary glands (SGs) are very important for maintaining the physiological functions of the mouth. When SGs regenerate and repair from various damages, including mechanical, radiological, and immune diseases, acinar and granular duct cells originate from intercalated duct cells. However, the recovery is often insufficient because of SGs' limited self-repair function. Furthermore, the precise repair mechanism has been unclear. Here, we focused on CD49f, one of the putative stem cell markers, and characterized CD49f positive cells (CD49f+ cells) isolated from male murine SGs. CD49f+ cells possess self-renewal ability and express epithelial and pluripotent markers. Compared to CD49f negative cells, freshly isolated CD49f+ cells highly expressed inhibin beta A and beta B, which are components of activin that has anti-proliferative effects. Notably, an inhibitor of activin, follistatin was expressed in mechanically-damaged SGs, meanwhile no follistatin was expressed in normal SGs in vivo. Moreover, sub-cultured CD49f+ cells highly expressed both Follistatin and a series of proliferative genes, expressions of which were decreased by Follistatin siRNA. These findings indicated that the molecular interaction between activin and follistatin may induce CD49f+ cells proliferation in the regeneration and repair of mouse SGs.

Abstract
AIM To describe beneficial effects of callosotomy on KCNQ2-related intractable epilepsy. CASE REPORT Our patient was a 10-year-old girl who had developed epilepsy during the neonatal period, accompanied by a suppression-burst pattern on the electroencephalography (EEG). The patient showed profound psychomotor developmental delay since early infancy. Daily seizures of versive posturing and ocular deviation were transiently controlled by carbamazepine and valproate at the age of 1 year; however, the seizures gradually increased to up to 50 times per day. Ictal EEG and positron emission tomography revealed an epileptic focus in the left frontal lobe at age 5 years. Total callosotomy resulted in marked reduction of epileptic seizures thereafter, as well as improved responses to external auditory and visual stimuli. Whole exome sequencing at age 9 identified a de novo missense variant in KCNQ2 (NM_172107.3:c.563A > C:p.(Gln188Pro)). CONCLUSION This case supports that epilepsy surgery could benefit children with epileptic encephalopathy, even with the etiology of channelopathy.

Abstract
Patients with infantile Alexander disease (AxD) usually do not survive beyond their early teens without life support care because of progressive central hypoventilation. We present the autopsy report of a woman with infantile AxD carrying an R239C mutation in the glial fibrillary acidic protein gene, who survived 39 years. She presented with psychomotor retardation in infancy and regressed after age 5. Brain computed tomography scans showed bilateral low frontal white matter density. She became quadriplegic with bulbar palsy and was intellectually handicapped after a measles infection at age 7. Tube feeding was introduced because of dysphagia at age 15. Noninvasive positive pressure ventilation was required due to central hypoventilation in her early thirties. She died of neurogenic respiratory failure at 39 years. Autopsy findings revealed a markedly atrophic brain (709 g, -6.0 standard deviation), especially in the frontal lobe, cerebellum, and brainstem portions. We found demyelination, gliosis, and cystic lesions throughout the brain, and we saw Rosenthal fibers accumulating in the perivascular spaces. We also identified a variety of abnormalities in other organs such as pancreatic necrosis, completely desquamated epithelium in the lower esophagus and stomach, foreign-body giant cells in the colon submucosa, glomerular sclerosis, and multiple bladder stones. This is the first autopsied case report of a patient with infantile AxD with long survival, who showed not only central nervous system characteristic findings, but also unexpected pathological changes in other organs.

Abstract
Introduction
Obstructive sleep apnea (OSA) is one of the common causes of hypertension. Therefore, we examine the longitudinal effect of continuous positive airway pressure (CPAP) therapy and its adherence on blood pressure among OSA patients.
Methods
One thousand two hundred ninety-three (male 1,130, female 163) patients, who were diagnosed with OSA and underwent CPAP therapy were investigated for longitudinal changes (24 months observation period) in the levels of blood pressure and body weight. The longitudinal analyses were performed by mixed effect model. Multiple Imputation with Chained Equations was also used to impute missing data. Good CPAP adherence is defined as more than 70% of the time using CPAP more than 4hours at all the measuring. Poor CPAP adherence is defined as less than 70% of the time using CPAP more than 4hours at all the measuring time points.
Results
The patient group with good CPAP adherences), compared to poor CPAP adherence, showed significant diastolic blood pressure reduction in 24 months follow-up period (β=-0.13, p=0.03) despite a lack of significant weight loss (β=-0.02, p=0.59). However, no significant associations were found between systolic blood pressure and CPAP adherence (β=-0.14, p=0.11).
Conclusion
CPAP therapy was found to have a longitudinal effect on diastolic blood pressure despite a lack of significant weight loss.

Abstract
BACKGROUND Commercial drivers suffering from excessive daytime sleepiness (EDS) have been identified as a major cause of road traffic accidents. Alcohol usage directly affects sleep, adversely affecting next-day alertness and performance. AIMS To examine the relationship between alcohol consumption and EDS among commercial truck drivers in Japan and the implications of this on public health. METHODS All participants in this cross-sectional study were commercial motor vehicle drivers from Tokyo and Niigata Prefecture. Participants completed a self-administered questionnaire with details of their age, body mass index, alcohol consumption, Epworth Sleepiness Scale (ESS) score and tobacco usage. Participants' oxygen desaturation index was determined by a pulse oximetry device that participants took home. RESULTS A total of 1422 males registered with the Japan Trucking Association and aged 20-69 years participated. The multivariate-adjusted odds ratio (OR) of EDS among participants aged <43 years was 0.81 (95% confidence interval (CI) 0.47-1.40) for light drinkers, 0.93 (95% CI 0.51-1.70) for moderate drinkers and 0.61 (95% CI 0.21-1.79) for heavy drinkers, compared to non-drinkers. The multivariate-adjusted OR among participants aged ≥43 years was 1.42 (95% CI 0.59-3.45) for light drinkers, 1.53 (95% CI 0.63-3.75) for moderate drinkers and 3.37 (95% CI 1.14-9.96) for heavy drinkers (P for interaction = 0.05). CONCLUSION We found that the association between ESS and alcohol intake was more evident among those aged ≥43 years, who reported higher levels of EDS with increased alcohol consumption.

Abstract
Interaction cross sections for ^{42-51}Ca on a carbon target at 280 MeV/nucleon have been measured for the first time. The neutron number dependence of derived root-mean-square matter radii shows a significant increase beyond the neutron magic number N=28. Furthermore, this enhancement of matter radii is much larger than that of the previously measured charge radii, indicating a novel growth in neutron skin thickness. A simple examination based on the Fermi-type distribution, and mean field calculations point out that this anomalous enhancement of the nuclear size beyond N=28 results from an enlargement of the core by a sudden increase in the surface diffuseness of the neutron density distribution, which implies the swelling of the bare ^{48}Ca core in Ca isotopes beyond N=28.

Abstract
Christianson syndrome (CS) is an X-linked intellectual disorder caused by mutations in the SLC9A6 gene. Clinical features of CS include an inability to speak, truncal ataxia, postnatal microcephaly, hyperkinesis, and epilepsy. Almost all patients with CS develop drug-resistant epilepsy-its most serious complication. We report two cases of CS with drug-resistant epilpesy associated with the Lennox-Gastaut syndrome (LGS). One patient experienced generalized tonic seizures since 9 months of age with cognitive regression, which evolved to include atonic seizures at the age of 7 years. Electroencephalography (EEG) showed generalized slow spike-wave complexes and generalized paroxysmal fast activity. Seizures remained drug-resistant despite multiple anti-seizure drugs. The second patient experienced generalized tonic seizures since the age of 17 months and arrested development. EEG showed generalized slow spike-wave complexes, with frequent atonic seizures since the age of 6 years. Electrical status epilepticus during slow-wave sleep (ESES) developed at the age of 7 years. Our cases illustrate that CS may cause LGS in addition to other developmental and epileptic encephalopathies of the neonatal and infantile period. We suggest that generalized tonic or tonic-clonic seizures and generalized slow spike-wave complexes in interictal EEG be included as potential electroclinical features of epilepsy in CS.

Abstract
A peak field of 1200 T was generated by the electromagnetic flux-compression (EMFC) technique with a newly developed megagauss generator system. Magnetic fields closely up to the turn-around peak were recorded by a reflection-type Faraday rotation magnetic-field optical-fiber probe. The performance was analyzed and compared with data obtained by the preceding EMFC experiments to show a significant increase in the liner imploding speed of up to 5 km/s.

Abstract
BACKGROUND Non-invasive positive pressure ventilation (NPPV) in children has recently increased worldwide and is used not only for neuromuscular diseases but for various other diseases. However, there have been few observational studies on long-term NPPV in children in Japan. METHODS Based on medical records, we retrospectively evaluated patients aged ≤20 years who were initiated long-term NPPV at our hospital from January 2001 to December 2015. RESULTS A total of 53 patients on long-term NPPV were identified; 38 (72%) had severe motor and intellectual disabilities (SMID). Compared to those with non-neuromuscular diseases, those with neuromuscular diseases had significantly more planned initiations and less frequent use of oxygen. Regarding patient outcome, 34 patients continued NPPV (64%), and there were three discontinues (6%), seven tracheostomies (13%), and nine deaths (17%). The continuation rate was high among those with neuromuscular disorders (15/19 cases, 79%) and that of tracheotomy was high in those with metabolic/degenerative diseases (3/9 cases, 33%). Ten patients transitioned to adult care, accounting for 29% of the 34 continuing patients. CONCLUSION This is the first observational study on long-term NPPV use in children in Japan that examined outcomes in patients with a range of disorders. The initiation situation, management, and outcomes differed between patients with neuromuscular and non-neuronal muscular diseases. Long-term use of NPPV is possible in many cases, including children with SMID, but can be challenging to continue in patients with progressive diseases such as metabolic/degenerative diseases. Careful discussions regarding the management of each patient are necessary.

Abstract
ZusammenfassungEine 2013 von der „International Federation of Clinical Neurophysiology“ gegründete Taskforce hat eine international konsensfähige EEG-Terminologie entwickelt. Im Folgenden soll das Resultat – die 2. Version des Standardized Computer-based Organized Reporting of EEG (SCORE) - vorgestellt werden. Die Terminologie wurde im Rahmen eines Softwarepaketes (SCORE-EEG) in der klinischen Praxis an über 12.000 EEGs getestet. Die Auswahl der Begriffe ist kontextabhängig: die initiale Auswahl bestimmt, welche weiteren Auswahlmöglichkeiten zur Verfügung stehen. Im Verlauf wird automatisch ein Befund erstellt und dessen Einzelmerkmale in eine Datenbank eingespeist. SCORE verfügt über Module spezifisch für die Befundung epileptischer Anfälle, sowie charakteristischer neonataler und intensivmedizinische EEG-Merkmale. SCORE ist nicht nur ein nützliches Werkzeug im ambulanten, klinischen und wissenschaftlichen Setting, es erleichtert auch Qualitätssicherung, Datenaustausch und die EEG-Aus und Weiterbildung.

Abstract
We have developed an artificial organ conditioning system in order not only to condition but also evaluate the viability for transplant graft of kidneys which have been stored for a long time and damaged by warm ischaemia following cardiac arrest. The conditioning system consisted of an artificial lung, a roller pump, an organ chamber and perfusate. The perfusate was prepared with electrolytes, fluorocarbon, amino acid, glucose, an oxygen scavenger and so on. Conditioning was performed by continuous perfusion under mild hypothermia at 24° C. Mildly damaged kidneys (0 and 30 minutes warm ischaemia rabbit kidneys) were well conditioned but severely damaged kidneys failed to produce urination. Our device successfully exposed the viability of stored kidneys and the successful conditioning of damaged kidneys due to warm ischaemia avoiding transplantation. By establishing our method, the harvesting of kidneys following cardiac arrest will be feasible.

Abstract
Cryofiltration (CRYO) removes cryogel, which is a combination of fibrinogen (Fbg) and fibronectin (FN), containing pathological substances. The purpose of this study was to measure cryogel EDA(+) FN and study the relationship between EDA(+) FN and clinical symptoms in patients with rheumatoid arthritis, SLE and polymyositis. Cryogel contains 51 times more EDA(+) FN than plasma. The patients with rheumatoid arthritis showed a high level of EDA(+) FN in their plasma, and the EDA(+) FN level in plasma corresponded with changes in joint pain. We calculated the clearance level at several points in cryofiltration, and the reduction enabled us to evaluate the CRYO device. The EDA(+) FN clearance was 23.3 ± 6.4 ml/min, the pFN clearance 16.5 ± 4.1 ml/min, and the Fbg clearance 22.9 ± 5.7 ml/min. As the plasma flow in cryofiltration was 30 ml/min, a clearance of EDA(+) FN and Fbg, approximately 23 ml/min, was obviously high. The study of the plasma level change of EDA(+) FN during cryofiltration revealed a temporary elevation. These results suggest that the EDA(+) FN was most efficiently reduced by cryofiltration, would become a good indicator on plasmapheresis, and might move from other tissues into the blood during cryofiltration.

Abstract
Ameloblasts responsible for enamel formation express matrix metalloproteinase 20 (MMP20), an enzyme that cleaves enamel matrix proteins, including amelogenin (AMELX) and ameloblastin (AMBN). Previously, we showed that continuously erupting incisors from transgenic mice overexpressing active MMP20 had a massive cell infiltrate present within their enamel space, leading to enamel mineralization defects. However, effects of MMP20 overexpression on mouse molars were not analyzed, although these teeth more accurately represent human odontogenesis. Therefore, MMP20-overexpressing mice ( Mmp20+/+Tg+) were assessed by multiscale analyses, combining several approaches from high-resolution micro-computed tomography to enamel organ immunoblots. During the secretory stage at postnatal day 6 (P6), Mmp20+/+Tg+ mice had a discontinuous ameloblast layer and, unlike incisors, molar P12 maturation stage ameloblasts abnormally migrated away from the enamel layer into the stratum intermedium/stellate reticulum. TOPflash assays performed in vitro demonstrated that MMP20 expression promoted β-catenin nuclear localization and that MMP20 expression promoted invasion through Matrigel-coated filters. However, for both assays, significant differences were eliminated in the presence of the β-catenin inhibitor ICG-001. This suggests that MMP20 activity promotes cell migration via the Wnt pathway. In vivo, the unique molar migration of amelogenin-expressing ameloblasts was associated with abnormal deposition of ectopic calcified nodules surrounding the adherent enamel layer. Enamel content was assessed just prior to eruption at P15. Compared to wild-type, Mmp20+/+Tg+ molars exhibited significant reductions in enamel thickness (70%), volume (60%), and mineral density (40%), and MMP20 overexpression resulted in premature cleavage of AMBN, which likely contributed to the severe defects in enamel mineralization. In addition, Mmp20+/+Tg+ mouse molar enamel organs had increased levels of inactive p-cofilin, a protein that regulates cell polarity. These data demonstrate that increased MMP20 activity in molars causes premature degradation of ameloblastin and inactivation of cofilin, which may contribute to pathological Wnt-mediated cell migration away from the enamel layer.

Abstract
Spinal muscular atrophy with respiratory distress type 1 (SMARD1) is characterized by severe respiratory failure due to diaphragmatic paralysis and distal muscular weakness in early infancy. After an initial decline in respiratory state and motor function until 1-2years of age, residual capabilities reach a plateau. We report the peripheral neuropathological findings of a patient with SMARD1 at 1year and 1month of age, when his muscle strength and respiratory symptoms had deteriorated and then stabilized for several months. Peripheral nerve biopsy revealed severely progressed axonal degeneration. This finding suggests the rapid progression of peripheral axonal neuropathy in SMARD1 that leads to its characteristic clinical course of respiratory failure and paralysis in the early infantile period.
