Autism spectrum disorder (ASD) is a complex and prevalent neurodevelopmental disorder characterized by deficits in social communication and social interaction as well as repetitive behaviors. Alterations in function connectivity are widely recognized in recent electroencephalogram (EEG) studies. However, most studies have not reached consistent conclusions, which could be due to the developmental nature and the heterogeneity of ASD.

Here, EEG coherence analysis was used in a cohort of children with ASD (n=13) and matched typically developing controls (TD, n=15) to examine the functional connectivity characteristics in long-distance and short-distance electrode pairs. Subsequently, we explore the association between the connectivity strength of coherence and symptom severity in children with ASD.

Compared with TD group, individuals with ASD showed increased coherence in short-distance electrode pairs in the right temporal-parietal region (delta, alpha, beta bands), left temporal-parietal region (all frequency bands), occipital region (theta, alpha, beta bands), right central-parietal region (delta, alpha, beta bands), and the prefrontal region (only beta band). In the long-distance coherence analysis, the ASD group showed increased coherence in bilateral frontal region, temporal region, parietal region, and frontal-occipital region in alpha and beta bands. The strength of such connections was associated with symptom severity.

Our study indicates that abnormal connectivity patterns in neuroelectrophysiology may be of critical importance to acknowledge the underlying brain mechanism.

A systematic search was performed on four databases, that is, PubMed, Scopus, Web of Science, and Cochrane Library, to identify relevant articles published up to December 31, 2019. LY450139 Included studies were limited to original investigations assessing the association between prenatal exposure to ACEIs/ARBs and adverse pregnancy outcomes. Odds ratios were used as a summary effect measure. Pooled-effect estimates of each outcome were calculated by the random-effects meta-analysis. The main outcomes included overall and specific congenital malformations, low birth weight, miscarriage, elective termination of pregnancy, stillbirth, and preterm delivery. Of 19 included articles involving a total of 4 163 753 pregnant women, 13 studies reported an increased risk of, at least, one adverse pregnancy outcome in pregnant women who were exposed to ACEIs/ARBs. Meta-analysis revealed a significant association between overall congenital malformations and first trimester-only exposure to ACEIs/ARBs (OR = 1.94, 95% CI = 1.71-2.21, P less then .0001). Cardiovascular malformations, miscarriage, and stillbirth also provided a significant relation with ACEI/ARB exposure. In conclusion, prenatal exposure to ACEIs/ARBs in the first trimester of pregnancy was found to be associated with an increased risk of adverse pregnancy outcomes. Women of reproductive age should be aware of the potential teratogenic risks of these drugs if they become pregnant.The aim of this study is to evaluate the psychometric properties of the Malay version of the Swanson, Nolan, and Pelham Parent Rating Scale of attention deficit hyperactivity disorders (ADHD) symptoms (M-SNAP-IV). For this purpose, the SNAP-IV scale was translated into the Malay language and was pilot-tested on 91 parents of children aged 8 to 11 years (ADHD [n = 36] and non-ADHD children [n = 55]). The findings depicted that the M-SNAP-IV has excellent content validity, internal consistency, and test-retest reliability. The M-SNAP-IV is a valid and reliable screening tool to detect ADHD symptoms in children and has the advantages to assess the specific presentation of ADHD.The primary cilium is a sensory organelle that receives specific signals from the extracellular environment important for vertebrate development and tissue homeostasis. link2 Lamins, the major components of the nuclear lamina, are required to maintain the nuclear structure and are involved in most nuclear activities. In this study, we show that deficiency in lamin A/C causes defective ciliogenesis, accompanied by increased cytoplasmic accumulation of actin monomers and increased formation of actin filaments. Disruption of actin filaments by cytochalasin D rescues the defective ciliogenesis in lamin A/C-depleted cells. Moreover, lamin A/C-deficient cells display lower levels of nesprin 2 and defects in recruiting Arp2, myosin Va, and tau tubulin kinase 2 to the basal body during ciliogenesis. Collectively, our results uncover a functional link between nuclear lamina integrity and ciliogenesis and implicate the malfunction of primary cilia in the pathogenesis of laminopathy.STXBP1, also known as Munc-18, is a master regulator of neurotransmitter release and synaptic function in the human brain through its direct interaction with syntaxin 1A. STXBP1 binds syntaxin 1A is an inactive conformational state. STXBP1 decreases its binding affinity to syntaxin upon phosphorylation, enabling syntaxin 1A to engage in the SNARE complex, leading to neurotransmitter release. STXBP1-related disorders are well characterized by encephalopathy with epilepsy, and a diverse range of neurological and neurodevelopmental conditions. Through exome sequencing of a child with developmental delay, hypotonia, and spasticity, we found a novel de novo insertion mutation of three nucleotides in the STXBP1 coding region, resulting in an additional arginine after position 39 (R39dup). Inconclusive results from state-of-the-art variant prediction tools mandated a structure-based approach using molecular dynamics (MD) simulations of the STXBP1-syntaxin 1A complex. Comparison of the interaction interfaces of the wild-type and the R39dup complexes revealed a reduced interaction surface area in the mutant, leading to destabilization of the protein complex. Moreover, the decrease in affinity toward syntaxin 1A is similar for the phosphorylated STXBP1 and the R39dup. We applied the same MD methodology to seven additional previously reported STXBP1 mutations and reveal that the stability of the STXBP1-syntaxin 1A interface correlates with the reported clinical phenotypes. This study provides a direct link between the outcome of a novel variant in STXBP1 and protein structure and dynamics. The structural change upon mutation drives an alteration in synaptic function.

Stellera chamaejasme L. is a poisonous plant with rich resources and is thus highly valuable in terms of new pesticide development. Isochamaejasmin (ICM), one of the main ingredients in S. chamaejasme has drawn much attention owing to its antitumour properties. However, the toxicity and mode of action of ICM on insects are still not clear. In this article, the larva and neuronal cell (AW1) of Helicoverpa zea were used to clarify the insecticidal activity of ICM as well as its toxic mechanism at the cellular level.

The results confirmed that ICM has potential toxicity against H. zea both in vivo and in vitro via time- and dose-dependent manners. Moreover, we found that ICM caused DNA damage and increased the levels of γH2AX and OGG1 in AW1 cells. Results also showed decline in the mitochondrial membrane potential (MMP), upregulation of Bax/Bcl-2 expression resulting in the release of cytochrome c into the cytosol, activation of caspase-3/9, and cleavage of poly ADP-ribose polymerase (PARP) as a result of exposure to ICM. Additionally, a dose-dependent rise in the reactive oxygen species (ROS) levels, accumulation of a lipid peroxidation product, and inactivation of antioxidant enzymes were found in ICM-treated cells.

These findings confirmed the insecticidal activity of ICM. Furthermore, the results revealed that ICM could cause DNA damage and induce apoptosis via the mitochondrial pathway in AW1 cells. This study provides the basic information needed to understand the toxicity and mechanisms of action of ICM, which could potentially be used to develop it as a new insecticide.

This article describes the management of a DC associated with tooth 21 in a seven-year-old Caucasian child with a history of multiple TDIs to the primary maxillary incisors. Chronic periapical inflammation associated with a necrotic pulp in tooth 61 was identified as the likely cause of the lesion. Initial conservative management involved marsupialization of the lesion by extracting the necrotic tooth 61. Following significant decompression of the cyst, surgical enucleation was carried out under general anaesthesia and an orthodontic attachment was bonded to the crown of the unerupted tooth 21 to facilitate traction. Histopathological assessment of the enucleated tissue confirmed it to be a DC. Two years after the initial presentation, teeth 21 and 22 had erupted into the oral cavity, improving patient aesthetics. However, the root of tooth 22 was transposed with the crown of the unerupted tooth 23. This case highlights the undesirable sequelae that may occur following delayed and inappropriate management of TDIs.

The Thai Type1 Diabetes and Diabetes Diagnosed Before Age 30 Years Registry, Care and Network was established in 2014 and involved 31 hospitals. The objective of the registry was to evaluate glycemic control and complications of patients with type1 diabetes.

Patients' demographics, clinical data, frequencies of daily self-monitoring of blood glucose (SMBG), glycemic control and complications were collected.

Among the 1,907 type1 diabetes patients, the mean age was 21.2±11.3years. The mean glycated hemoglobin level was 9.35±2.41%, with significant variations among age groups (P<0.001). Conventional insulin treatment and intensive insulin treatment were used in 43 and 57% of patients, respectively. link3 Mean glycated hemoglobin levels were significantly higher in patients treated with conventional insulin treatment compared to those treated with intensive insulin treatment (9.63±2.34 vs 9.17±2.46%, P=0.002). Compared to the conventional insulin treatment group, significantly more patients in the intensive insulin treatment group achieved good glycemic control (P<0.001), and fewer had diabetic retinopathy (P=0.031). The prevalence of microvascular complications increased significantly with age (P<0.001). Multivariate analysis showed good glycemic control to be associated with age 25 to <45years, intensive insulin treatment with SMBG three or more times daily and diabetes duration of 1 to <5years.

Most Thai type1 diabetes patients were not meeting the recommended glycemic target. As a result of this study, the national program to improve the quality of diabetes treatment and education has been implemented, and the results are ongoing.
