Jong-Geun Seo, Gun-Hee Lee, Sung-Pa Park
PURPOSE: Apathy as a state of decreased motivation has not been highlighted in people with epilepsy (PWE). We investigated its clinical significance in PWE. METHODS: We invited adult PWE who had been administered antiepileptic drugs (AEDs) for at least 1year and compared them with age- and gender-matched healthy controls. Eligible participants completed several questionnaires including the Apathy Evaluation Scale-Self (AES-S), the Korean version of the Neurological Disorders Depression Inventory for Epilepsy (K-NDDI-E), the Generalized Anxiety Disorder-7 (GAD-7), the Epworth Sleepiness Scale (ESS), and the Insomnia Severity Index (ISI), and the Quality of Life in Epilepsy-10 (QOLIE-10)...

The effect of various anthropogenic sources of noise (e.g. sonar, seismic surveys) on the behaviour of marine mammals is sometimes quantified as a dose-response relationship, where the probability of an animal behaviourally 'responding' (e.g. avoiding the source) increases with 'dose' (or received level of noise). To do this, however, requires a definition of a 'significant' response (avoidance), which can be difficult to quantify. There is also the potential that the animal 'avoids' not only the source of noise but also the vessel operating the source, complicating the relationship...

Zooplankton underpin the health and productivity of global marine ecosystems. Here we present evidence that suggests seismic surveys cause significant mortality to zooplankton populations. Seismic surveys are used extensively to explore for petroleum resources using intense, low-frequency, acoustic impulse signals. Experimental air gun signal exposure decreased zooplankton abundance when compared with controls, as measured by sonar (~3-4 dB drop within 15-30 min) and net tows (median 64% decrease within 1 h), and caused a two- to threefold increase in dead adult and larval zooplankton...

BACKGROUND: The World Health Organization has declared suicide a global ealth crisis, predicting that ~1.53 million people will commit suicide annually by 2020. OBJECTIVE: A study from South Africa reviewed 1 018 suicide cases in Pretoria over 4 years (1997 - 2000). Our study was undertaken to establish whether there have been substantial changes in the profile of suicide victims who died in Pretoria a decade later. METHODS: Case records at the Pretoria Medico-Legal Laboratory were reviewed retrospectively from 2007 to 2010...

There is a critical knowledge gap regarding the impacts of seismic air gun signals on the physiology of adult crustaceans. We conducted four controlled field experiments to examine the impact of seismic acoustic signals on spiny lobster, Jasus edwardsii. Seismic air gun exposure suppressed total haemocyte count (THC) for up to 120days post-exposure, suggesting a chronic negative impact of immune competency. THC levels after 365days post-exposure, were elevated two fold, potentially indicating an immune response to infection...

Vapor phase carbon (C)-reduction-based syntheses of C nanotubes and graphene, which are highly functional solid C nanomaterials, have received extensive attention in the field of materials science. This study suggests a revolutionary method for precisely controlling the C structures by oxidizing solid C nanomaterials into gaseous products in the opposite manner of the conventional approach. This gaseous nanocarving enables the modulation of inherent metal assembly in metal/C hybrid nanomaterials because of the promoted C oxidation at the metal/C interface, which produces inner pores inside C nanomaterials...

Mass public shootings are typically followed by a spike in gun sales as well as calls for stricter gun control laws. What remains unclear is whether the spike in gun sales is motivated by increased threat perceptions or by concerns about gun control, or whether the sales are mainly driven by non-owners purchasing guns or gun owners adding to their collection. Two surveys of gun owners and non-owners, conducted immediately before and after the Orlando shooting, allowed us to assess its impact on threat perceptions and on gun-purchasing intentions...

The nanosphere lithography (NSL) method can be developed to deposit the Au-Ag triangle hexagonal nanoparticle arrays for the generation of localized surface plasmon resonance. Previously, we have found that the parameters used to form the NSL masks and the physical methods required to deposit the Au-Ag thin films had large effects on the geometry properties of the nanoparticle arrays. Considering this, the different parameters used to grow the Au-Ag triangle hexagonal nanoparticle arrays were investigated. A single-layer NSL mask was formed by using self-assembly nano-scale polystyrene (PS) nanospheres with an average radius of 265 nm...

OBJECTIVES: Reducing access to firearms as a suicide prevention strategy is limited in the US today because of divergent cultural attitudes and political contentiousness surrounding gun restrictions. This research examined the effects of culturally-specific suicide prevention messages on the likelihood of restricting firearm access during periods of suicide risk. METHODS: Focus groups and key informant interviews were conducted with rural gun owners in order to develop a suicide prevention message that highlighted the importance of restricting access to firearms during periods of risk without threatening second amendment concerns...

BACKGROUND: Repetitive transcranial magnetic stimulation (TMS) is a non-invasive, safe, and efficacious treatment for depression. TMS has been shown to normalize abnormal functional connectivity of cortico-cortical circuits in depression and baseline functional connectivity of these circuits predicts treatment response. Less is known about the relationship between functional connectivity of frontostriatal circuits and treatment response. OBJECTIVE/HYPOTHESIS: We investigated whether baseline functional connectivity of distinct frontostriatal circuits predicted response to TMS...

In noise-induced hearing loss (NIHL), noise exposure damages cochlear sensory hair cells, which lack the capacity to regenerate. Following noise insult, intense metabolic activity occurs, resulting in a cochlear free radical imbalance. Oxidative stress and antioxidant enzyme alterations, including lipoxygenase upregulation, have been linked to chronic inflammation, which contributes to hearing impairment. We previously proposed Scutellaria baicalensis (SB) extract as an alternative therapeutic for preventing NIHL and attributed its pharmacological effects to baicalein...

Customized gene-panel tests, based on next-generation sequencing, have demonstrated their usefulness in a plethora of clinical settings. As with other clinical diagnostic techniques, gene-panel sequencing for clinical purposes requires precise quality control (QC) measures to ensure its reliability. Only detected variants are currently recorded in clinical reports; however, identifying whether a nondetected variant is a true or false negative is regarded essential in a clinical setting and, thus, a comprehensive QC measure is in demand...

The skin hosts a variety of dendritic cells (DCs), which act as professional APC to control cutaneous immunity. Langerhans cells (LCs) are the only DC subset in the healthy epidermis. However, due to the complexity of the skin DC network, their relative contribution to either immune activation or immune tolerance is still not entirely understood. To specifically study the function of LCs in vivo, without altering the DC subset composition in the skin, we have generated transgenic mouse models for tamoxifen-inducible de novo expression of Ags in LCs but no other langerin(+) DCs...

Objective: In the present study, we examined whether the post-prandial reduction in plasma growth hormone (GH) levels is related to the increase in plasma insulin levels in ruminants. Methods: We performed two experiments: intravenous bolus injection of insulin (0.2 IU/kg body weight) or glucose (1.0 mmol/kg body weight) was administered to increase the plasma insulin levels in male Shiba goats. Results: In the insulin injection experiment, significant (p<0...

While the influence of nanotopography on stem cell behavior have been extensively investigated on adult stem cells, far fewer studies have investigated the interaction of induced pluripotent stem cells (iPSC) with various nanotopographical patterns. The purpose of this study was to identify nanopatterns that can influence the stemness and proliferation as well as the adhesive properties in iPSCs, and thereby explore the feasibility of applying these nano-features for regenerative medicine. Three kinds of nanopatterns were fabricated from polydimethylsiloxane (PDMS) membranes, irregular patterned membrane (IPM), groove patterned membrane (GPM), and post patterned membrane (PPM), in addition to flat patterned membrane (FPM) which did not have any nanotopographic features and was used as the control pattern...

To decrease the gastric cancer related mortality rate, endoscopic screening is widely performed in Korea. However, a precise method for identifying those at a high risk of gastric neoplasms has not been established. This study aims to evaluate serum pepsinogen (PG) levels for risk assessment of gastric neoplasms. Between August 2014 and March 2016, a total of 398 subjects, including 87 with gastric neoplasms, were enrolled in this study. On the basis of the serum PG I/II ratio, the enrolled subjects were classified into 4 groups: group A, PG I/II ratio >4; group B, >3 and ≤4; group C, >2 and ≤3; group D, ≤2...
