Background: Maternal alcohol use during pregnancy has repeatedly been associated with development of attention-deficit hyperactivity disorder (ADHD) in the offspring. It is, however not known whether this reflects a direct casual intra-uterine effect or a non-causal relationship due to confounding. We used three different approaches to control for measured and unmeasured confounding: statistical adjustment for covariates, negative control comparison against maternal pre-pregnancy alcohol use, and comparison among differentially exposed siblings...

BACKGROUND: Aggregated amyloid-β peptide 1-42 (Aβ42), derived from the cellular amyloid precursor protein, is one of the pathological hallmarks of Alzheimer's disease (AD). Although active immunization against Aβ42 peptide was successful in AD mouse models and led to removal of plaques and improved memory, a similar clinical trial in humans (Aβ42 peptide immunization with QS-21 adjuvant) was stopped in phase II, when 6% of the treated patients developed encephalitis. Currently ongoing passive immunizations with the injection of preformed monoclonal antibodies against different epitopes within the Aβ1-42 peptide, which do not lead to activation of the immune system, have shown some effects in slowing AD pathology...

PURPOSE: To evaluate the safety and efficacy of selective retina therapy (SRT) with real-time feedback-controlled dosimetry (RFD) in the treatment of chronic central serous chorioretinopathy (CSC). METHODS: In this retrospective case series study, 50 eyes of 49 patients with chronic CSC demonstrating focal or diffuse foveal leakages on fundus fluorescein angiography (FFA) were included. Following evaluation of test spots at temporal arcades, SRT (wavelength 527 nm, pulse repetition rate 100 Hz, pulse energy ramp with maximal 15 pulses) with retinal spot diameter of 200 μm was applied to the areas of each leakage observed on fluorescein angiography...

BACKGROUND: Delayed nausea after chemotherapy remains a symptom of interest. Clinicians often provide additional and/or pro re nata (p.r.n.) antiemetics with guideline-consistent antiemetics in an attempt to achieve further symptom control. Whether the usage of additional and/or p.r.n. antiemetics provide added benefit remains as a question. OBJECTIVE: The purpose of this study was to determine the benefit of providing additional antiemetics and/or p.r.n. antiemetics with guideline-consistent antiemetics in the control of nausea, functioning, and quality of life (QOL)...

Heart rate recovery (HRR) is a strong mortality predictor. Exercise training (ET) and β-blocker therapy have significant impact on the HRR of patients following myocardial infarction (MI). However, the combination of ET and β-blocker therapy, as well as its effectiveness in patients with a more compromised HRR (≤12 bpm), has been under-studied. Male patients (n = 64) post-MI were divided: Training + β-blocker (n = 19), Training (n = 15), β-blocker (n = 11) and Control (n = 19). Participants performed an ergometric test before and after 3 months of intervention...

Five centrosymmetric and one dipolar pyrrolo[3,2-b]pyrroles, possessing, respectively, either two- or one strongly electron-withdrawing nitro groups have been synthesized in a straightforward manner from simple building blocks. In the symmetric compounds the nitroaryl groups induced spontaneous breaking of inversion symmetry in the excited-state, leading to large solvatofluorochromism. To study the origin of this effect, the series employed peripheral structural motifs that control the degree of conjugation via altering of dihedral angle between the 4-nitrophenyl moiety and the electron-rich core...

Diarrhea is a leading cause of increased mortality in neonatal and young piglets. Aberration of the gut microbiota is one important factor in the etiology of piglet diarrhea. However, information regarding the structure and function of the gut microbiome in diarrheic neonatal piglets is limited. To investigate the composition and functional potential of the fecal microbiota in neonatal piglets, we performed 16S rRNA gene sequencing on 20 fecal samples from diarrheic piglets and healthy controls, and metagenomics sequencing on a subset of six samples...

BACKGROUND: Impaired sleep quality is common and associated with an increased risk of cardiovascular disease (CVD), thought to be mediated through adverse effects on established vascular risk factors, particularly hypertension. We determined if a web-delivered sleep intervention (sleep-hygiene education, stimulus control, and cognitive behavioral therapy) reduces blood pressure compared to vascular risk factor education (standard care) alone. METHODS: Phase II randomized, blinded, controlled trial of 134 participants without CVD with mild sleep impairment and blood pressure 130-160/<110 mm Hg...

BACKGROUND/AIM: Although microRNAs (miRNAs) are known to influence messenger RNA post-transcriptional control and contribute to human tumorigenesis, little is known about the differences in miRNA expression between primary and recurrent epithelial ovarian cancer (EOC). The purpose of this study was to assess the differential miRNA expression between primary and recurrent EOC and to investigate whether miR-196b could regulate the expression of the Homeobox A9 (HOXA9) gene, and thus affect the invasiveness of cancer cells in recurrent EOC...

Three experiments were designed to test whether experimentally created ad hoc associative networks evoke false memories. We used the DRM (Deese, Roediger, McDermott) paradigm with lists of ad hoc categories composed of exemplars aggregated toward specific goals (e.g., going for a picnic) that do not share any consistent set of features. Experiment 1 revealed considerable levels of false recognitions of critical words from ad hoc categories. False recognitions occurred even when the lists were presented without an organizing theme (i...

The actin cytoskeleton is a polymer system that acts both as a sensor and mediator of apoptosis. Tropomyosins (Tpm) are a family of actin binding proteins that form co-polymers with actin and diversify actin filament function. Previous studies have shown that elevated expression of the tropomyosin isoform Tpm2.1 sensitized cells to apoptosis induced by cell detachment (anoikis) via an unknown mechanism. It is not yet known whether Tpm2.1 or other tropomyosin isoforms regulate sensitivity to apoptosis beyond anoikis...

Controlling the thickness of quantum dot (QD) films is difficult using existing film formation techniques, which employ pre-ligand-exchanged PbS QD inks, because of several issues: 1) poor colloidal stability, 2) use of high-boiling-point solvents for QD dispersion, and 3) limitations associated with one-step deposition. Herein, we suggest a new protocol for QD film deposition using electrical double-layered PbS QD inks, prepared by solution-phase ligand exchange using methyl ammonium lead iodide (MAPbI3). The films are deposited by the supersonic spraying technique, which facilitates the rapid evaporation of the solvent and the subsequent deposition of the PbS QD ink without requiring a post-deposition annealing treatment for solvent removal...

BACKGROUND: Lead (Pb) is a toxic substance with well-known, multiple, long-term, adverse health outcomes. Shooting guns at firing ranges is an occupational necessity for security personnel, police officers, members of the military, and increasingly a recreational activity by the public. In the United States alone, an estimated 16,000-18,000 firing ranges exist. Discharge of Pb dust and gases is a consequence of shooting guns. METHODS: The objectives of this study are to review the literature on blood lead levels (BLLs) and potential adverse health effects associated with the shooting population...

A hand exoskeleton driven by myoelectric pattern recognition was designed for stroke rehabilitation. It detects and recognizes the user's motion intent based on electromyography (EMG) signals, and then helps the user to accomplish hand motions in real time. The hand exoskeleton can perform six kinds of motions, including the whole hand closing/opening, tripod pinch/opening, and the "gun" sign/opening. A 52-year-old woman, 8 months after stroke, made 20× 2-h visits over 10 weeks to participate in robot-assisted hand training...

Purpose: Lapatinib is a candidate drug for treatment of trastuzumab-resistant, HER2-positive gastric cancer (GC). Unfortunately, lapatinib resistance renders this drug ineffective. The present study investigated the implication of forkhead box protein O1 (FOXO1) signaling in the acquired lapatinib resistance in HER2-positive GC cells. Materials and Methods: Lapatinib-resistant GC cell lines (SNU-216 LR2-8) were generated in vitro by chronic exposure of lapatinib-sensitive, HER2-positive SNU-216 cells to lapatinib...

BACKGROUND: The relationship between dehydroepiandrosterone sulfate (DHEA-S) and bone mineral density (BMD) is controversial. And findings of most studies that have investigated this relationship are restricted to postmenopausal women. In this study, we investigated the relationship between serum DHEA-S and BMD in both men and women. METHODS: This cross-sectional study evaluated a total of 294 healthy Korean participants through a medical examination program. And a subgroup of 154 participants was subjected to a longitudinal analysis...

Three different types of fluorescent gold clusters (namely blue, green and red emitting) have been prepared from a gold precursor (chloroauric acid) under moderate conditions in aqueous medium. A cysteine containing dipeptide has been used for the formation of these quantum clusters as this peptide molecule contains a thiol group in the side chain to cap these nascently formed clusters and the free amino and carboxylic moieties assist in water solubility. Thus, the clusters are also environmentally friendly as the capped peptide is made up of only naturally occurring protein amino acids...

Consumer-grade distance sensors, such as the Microsoft Kinect devices (v1 and v2), have been investigated for use as marker-free motion monitoring systems for radiotherapy. The radiotherapy delivery environment is challenging for such sensors because of the proximity to electromagnetic interference (EMI) from the pulse forming network which fires the magnetron and electron gun of a linear accelerator (linac) during radiation delivery, as well as the requirement to operate them from the control area. This work investigated whether using Kinect v2 sensors as motion monitors was feasible during radiation delivery...

Most theories of lie detection assume that lying increases cognitive load, resulting in longer response latencies during questioning. However, the studies supporting this theory are typically laboratory-based, in settings with no specific validity in security contexts. Consequently, using virtual reality (VR), we investigated how response latencies were influenced in an ecologically valid environment of interest to security professionals. In a highly realistic airport security terminal presented in VR, a security officer asked participants yes/no questions about their belongings...
