INTRODUCTION: Epilepsy surgery is an effective treatment for refractory focal epilepsy. Risks of surgery need to be considered when advising individuals of treatment options. We describe the frequency and nature of physical adverse events associated with epilepsy surgery in a single center. MATERIAL AND METHODS: We reviewed the prospectively maintained records of adults who underwent epilepsy surgery at our center between 1990 and 2014 to identify peri/postsurgical adverse events...

OBJECTIVE: A major terror attack occurred in the Paris region on 13th November 2015. This event was widely showed, described, and commented in the media. Media consumption may lead to a widespread diffusion of trauma-related symptoms following a collective trauma. These effects may depend on the type of media and emotion regulation strategies used by the media consumer. METHOD: Trauma history, traumatic symptoms, media consumption, psychological distress, and emotion regulation strategies of 451 young adults were assessed by an online survey...

Mitochondria undergo morphological changes through fusion and fission for their quality control, which are vital for neuronal function. In this study, we examined three-dimensional morphologies of mitochondria in motor neurons under normal, nerve injured, and nerve injured plus fission-impaired conditions using the focused ion beam/scanning electron microscopy (FIB/SEM), because the FIB/SEM technology is a powerful tool to demonstrate both 3D images of whole organelle and the intra-organellar structure simultaneously...

Telomerase expression and activity appear elevated in >80% of human cancers. The activity of the telomerase may serve as a diagnostic marker for malignancy, and an indicator of the proliferative potential of somatic and stem cells. The telomeric repeat amplification protocol (TRAP) is a sensitive and accurate PCR-based assay for telomerase detection and measurement. Here, we describe a quantitative PCR-based TRAP assay (qTRAP) that is more convenient and amenable to high-throughput applications compared to traditional gel-based TRAP assays...

PURPOSE: Smartphones are prevalently used among adolescents; however, nighttime exposure to blue-enriched light, through electric devices, is known to induce delays of the circadian rhythm phases and poor morning somatic conditions. We therefore investigated whether evening smartphone use may affect sleep-wake cycle and cardiac autonomic nervous system (ANS) activity after awaking in dormitory students. METHODS: The participants were high school students, living under dormitory rules regarding the curfew, study, meals, lights-out, and wake-up times...

Context: Gastrointestinal Stromal Tumors (GISTs) are mesenchymal tumors of the gastrointestinal tract arising from the interstitial cells of Cajal. Succinate dehydrogenase (SDH) deficient GISTs are a unique class of GIST defined by: loss of immunohistochemical expression of SDHB indicating dysfunction of the mitochondrial complex 2, lack of driver mutations in KIT and PDGFRA, and a distinctive morphology and natural history. To date, all reported SDH-deficient GISTs have arisen in the stomach...

Insulin-like growth factor 1 (IGF1) is a multifunctional peptide that is involved in a wide range of physiological and patho-physiological processes in many animal species, ranging from somatic growth in children to metabolism, and tissue regeneration and repair in adults. The IGF1 gene is under multifactorial regulation in the few species in which it has been studied, with major control being exerted by growth hormone (GH) through a gene expression pathway involving inducible binding of the STAT5b transcription factor to dispersed enhancer elements...

We wish to identify determinants of endothelial lineage. Murine embryonic stem cells (mESC) were fused with human endothelial cells in stable, non-dividing, heterokaryons. Using RNA-seq it is possible to discriminate between human and mouse transcripts in these chimeric heterokaryons. We observed a temporal pattern of gene expression in the ESCs of the heterokaryons that recapitulated ontogeny, with early mesodermal factors being expressed before mature endothelial genes. A set of transcriptional factors not known to be involved in endothelial development was upregulated, one of which was POU class 3 homeobox 2 (Pou3f2)...

BACKGROUND: Increased activity of the three major physiological stress systems (immune-inflammatory system, hypothalamic-pituitary-adrenal-axis [HPA-axis], and autonomic nervous system [ANS]) is part of the pathophysiology of various somatic and psychiatric diseases. Oxidative damage is a key mechanism in both ageing and disease. Elucidating the relationship between these stress systems and oxidative damage would contribute to the understanding of the role of physiological stress in disease...

Patient carriers of a C9orf72 repeat expansion exhibit remarkable heterogeneous clinical and pathological characteristics suggesting the presence of modifying factors. In accordance with other repeat expansion diseases, repeat length is the prime candidate as a genetic modifier. Observations of earlier onset ages in younger generations of large families suggested a mechanism of disease anticipation. Yet, studies of repeat size and onset age have led to conflicting results. Also, the correlation between repeat size and diagnosis is poorly understood...

REVIEW

Germinal centers (GCs) form in secondary lymphoid tissues in response to antigenic challenge and are the site of somatic hypermutation, generating GC B cells with increasing affinity for the inciting agent that are positively selected over time. However, it is not until GC B cells differentiate into memory B cells and plasma cells and egress from the GC back into the circulation that effective long-lived humoral immunity is conferred upon the host. Here we review what is known about the signals that initiate the transition from a GC B cell into the memory B cell and plasma cell compartments and the downstream transcriptional regulation of these processes...

BACKGROUND: Dimensional approaches in highly prevalent psychiatric disorders like depression or anxiety could lead to a better understanding of pathogenesis and advantages in early detection and prevention. In an effort to better understand associations of brain structural variation across the depression/anxiety spectra, we investigated minor subclinical symptoms in a non-clinical healthy population. METHODS: We studied 177 healthy subjects from the community, who underwent high-resolution T1-weighted 3T MRI and completed the symptom-checklist-90 (SCL-90-R)...

Mutation analysis in single-cell genomes is prone to artifacts associated with cell lysis and whole-genome amplification. Here we addressed these issues by developing single-cell multiple displacement amplification (SCMDA) and a general-purpose single-cell-variant caller, SCcaller (https://github.com/biosinodx/SCcaller/). By comparing SCMDA-amplified single cells with unamplified clones from the same population, we validated the procedure as a firm foundation for standardized somatic-mutation analysis in single-cell genomics...

The major breast cancer suppressor proteins BRCA1 and BRCA2 play essential roles in homologous recombination (HR)-mediated DNA repair, which is thought to be critical for tumor suppression. The two BRCA proteins are linked by a third tumor suppressor, PALB2, in the HR pathway. While truncating mutations in these genes are generally pathogenic, interpretation of missense variants remains a challenge. To date, patient-derived missense variants that disrupt PALB2 binding have been identified in BRCA1 and BRCA2; however, there has not been sufficient evidence to prove their pathogenicity in humans, and no variants in PALB2 that disrupt either its BRCA1 or BRCA2 binding have been reported...

Several studies have investigated which management practices have the greatest effect on udder health, but little information is available on how broadly the recommended milking practices are adopted across Canada. The National Dairy Study 2015 was designed to gather dairy cattle health and management data on dairy farms across Canada. The objectives of the present study were to describe the current proportions of adoption of milking practices on Canadian dairy farms, and identify factors associated with their use on farms...

Extensive efforts have been made to identify more feed-efficient dairy cows, yet it is unclear how selection for feed efficiency will influence metabolic health. The objectives of this research were to determine the relationships between residual feed intake (RFI), a measure of feed efficiency, body condition score (BCS) change, and hyperketonemia (HYK) incidence. Blood and milk samples were collected twice weekly from cows 5 to 18 d postcalving for a total of 4 samples. Hyperketonemia was diagnosed at a blood β-hydroxybutyrate (BHB) ≥1...

Few studies have focused on premenstrual symptoms in employees. This study explored the prevalence of premenstrual symptoms in 7,193 female employees aged 18-55 years in a large electronics manufacturer in Taiwan from August 2014 to December 2014 and examined whether regular exercise was associated with premenstrual symptoms. Information was collected on demographics, lifestyle, menstrual history, menstrual pain, and premenstrual symptoms. Half of the participants reported irregular menstruation; 79.4% reported a moderate menstruation amount, and half reported little impact of menstrual pain at work...

Although the assessment of empathy has moved from general empathy to differentiating between cognitive and affective empathy, no instruments have assessed somatic (motor) empathy, and none have separated positive from negative affect empathy. The main objective of this study was to develop a 30-item self-report cognitive, affective, and somatic empathy scale (CASES) with positive and negative affect components for use with children and adolescents. A community sample of 428 male and female 11-year-olds completed the CASES together with validity questionnaires and were assessed on IQ...
