Electroconvulsive therapy (ECT) is effective in the treatment of treatment-resistant major depression. The fear of cognitive impairment after ECT often deters patients from choosing this treatment option. There is little reliable information regarding the effects of ECT on overall cognitive performance, while short-term memory deficits are well known but not easy to measure within clinical routines. In this pilot study, we examined ECT recipients' pre- and post-treatment performances on a digital ascending number tapping test...

Tapping in time to a metronome beat (hereafter beat synchronization) shows considerable variability in child populations, and individual differences in beat synchronization are reliably related to reading development. Children with developmental dyslexia show impairments in beat synchronization. These impairments may reflect deficiencies in auditory perception of the beat which in turn affect auditory-motor mapping, or may reflect an independent motor deficit. Here, we used a new methodology in EEG based on measuring beat-related steady-state evoked potentials (SS-EPs, Nozaradan et al...

Isothiocyanates, which are present as glucosinolate precursors in cruciferous vegetables, have strong activity against various cancers. Here, we compared the anti-metastatic effects of isothiocyanates (benzyl isothiocyanate (BITC), phenethyl isothiocyanate (PEITC), and sulforaphane (SFN)) by examining how they regulate MMP-9 expression. Isothiocyanates, particularly PEITC, suppressed 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced MMP-9 activity and invasion in various cancer cell lines. By contrast, N-methyl phenethylamine, a PEITC analog without an isothiocyanate functional group, had no effect...

INTRODUCTION: Objective, portable measures of motor function for out-of-office assessments are needed in Parkinson's Disease (PD). This study had 3 objectives. First, to examine change in objective motor measurements in PD (as assessed with the Objective PD Measurement (OPDM) system). Second, to correlate objective measures with clinical features and putative PD cerebrospinal fluid (CSF) and dopaminergic imaging biomarkers. Third, to assess participant compliance with and perceptions of serial in-home motor assessments...

Anteromedial maxillectomy is typically performed in conjunction with low-dose radiotherapy and intraarterial chemotherapy. In doing so, the extent of surgical defects is reduced. However, nasal deviation and oral incompetence may ensue, due to cicatricial contracture of wounds, and may be distressing to these patients. Herein, we report a series of eight free perforator flap procedures (anterolateral thigh [ALT] flap, 6; thoracodorsal artery perforator [TAP] flap, 2) used to correct such deformities. The TAP flap was combined with scapular tip [ST] osseous flap in patients with added zygomatic prominence defects...

The increasingly wide use of semiconductor nanocrystals inevitably leads to their release into aquatic environment. The aggregation behaviors of 3-mercaptopropionic acid-capped CdSe/CdS core-shell quantum dots (MPA-QDs) under various water chemistry conditions were examined and their removal using Fe(3+) and Al(3+) coagulants was evaluated. Cationic species rather than concentrations affected the stability of MPA-QDs. Adding 2 mM Ca(2+) led to a much larger ζ-potential decrease and particle size increase than adding 150 mM K(+) at each tested solution pH...

The core-shell structured PS/SiO2 composite nanospheres were synthesized on the basis of a modified Stöber method. The mechanical properties of monodisperse nanospheres were characterized with nanoindentation on the basis of the atomic force microscopy (AFM). The surface morphologies of PS/SiO2 composite nanospheres was scanned with the tapping mode of AFM, and the force-distance curves were measured with the contact mode of AFM. Different contact models were compared for the analyses of experimental data...

  Membrane technology, being the most emerging wastewater treatment option, has gained substantial importance with the massive objective of the reuse potential of wastewater. Keeping this in view, the present study was conducted with the rationale to evaluate the performance efficiency of membrane-based septic tank (MBST), and its reuse perspective for irrigating crops. The septic tank was designed by submerging a woven fiber microfiltration membrane module to treat domestic wastewater. Three crops Triticum aestivum (wheat), Coriandrum sativum (coriander), and Mentha arvensis (mint) were selected to be irrigated with treated MBST effluent, untreated wastewater, and tap water (as a control) for comparative growth analysis...

BACKGROUND: One major consequence of economic development in South-East Asia has been a rapid expansion of rubber plantations, in which outbreaks of dengue and malaria have occurred. Here we explored the difference in risk of exposure to potential dengue, Japanese encephalitis (JE), and malaria vectors between rubber workers and those engaged in traditional forest activities in northern Laos PDR. METHODOLOGY/PRINCIPAL FINDINGS: Adult mosquitoes were collected for nine months in secondary forests, mature and immature rubber plantations, and villages...

Gamma activity in the subthalamic nucleus (STN) is widely viewed as a pro-kinetic rhythm. Here we test the hypothesis that rather than being specifically linked to movement execution, gamma activity reflects dynamic processing in this nucleus. We investigated the role of gamma during fast stopping and recorded scalp electroencephalogram and local field potentials from deep brain stimulation electrodes in 9 Parkinson's disease patients. Patients interrupted finger tapping (paced by a metronome) in response to a stop-signal sound, which was timed such that successful stopping would occur only in ~50% of all trials...

INTRODUCTION: The concepts of Enhanced Recovery After Surgery (ERAS(®)) have steadily increased in usage, with benefits in patient outcomes and hospital length of stay. One important component of successful implementation of ERAS protocol is optimized pain control, via the multimodal approach, which includes neuraxial or regional anesthesia techniques and reduction of opioid use as the primary analgesic. Transversus abdominis plane (TAP) block is one such regional anesthesia technique, and it has been widely studied in abdominal surgery...

INTRODUCTION: Principles of enhanced recovery after surgery (ERAS(®)) protocols are well established, with the primary goal of optimizing perioperative care and recovery. The use of multimodal analgesia is a key component of these protocols, including regional analgesia techniques such as thoracic epidural analgesia (TEA), transversus abdominis plane (TAP), rectus sheath blocks or continuous wound infiltration (CWI)/catheters, and spinal anesthesia. We compare and contrast regional anesthesia approaches in different institutional colorectal surgery ERAS protocols...

One of the long-standing challenges in upper limb prosthetics is restoring the sensory feedback that is missing due to amputation. Two approaches have previously been presented to provide various types of sensory information to users, namely, multi-modality sensory feedback and using an array of singlemodality stimulators. However, the feedback systems used in these approaches were too bulky to be embedded in prosthesis sockets. In this paper, we propose an electrocutaneous sensory feedback method that is capable of conveying two modalities simultaneously with only one electrode...

The acute toxicity of carbosulfan and chlorpyrifos in formulated pesticides to glochidia (larvae) of the freshwater mussel (Hyriopsis bialata Simpson, 1900) was evaluated under static conditions in moderately hard dechlorinated tap water. Measured pesticide concentrations were 26 to 34% lower than nominal concentrations; therefore, all results are expressed in terms of measured active ingredient. Carbosulfan was relatively non-toxic to the mussel larvae with median effective concentrations (EC50) of carbosulfan at 24 and 48 h greater than 0...

We herein firstly reported that a patient with thymoma-associated pemphigus (TAP) underwent a robotic-assisted trans-subxiphoid thoracoscopic extended thymectomy and then achieved stable resolution. The patient, a 47-year-old male, was first admitted to our hospital owing to stomatitis and bullae of the trunk after four months' prednisone treatment. On admission, chest computed tomography (CT) revealed an anterior-mediastinal mass and it was initially diagnosed as a thymoma. He was positive for anti-BP (bullous pemphigoid)-180 antibody and anti-desmoglein 3 antibody...

Impaired manual dexterity is commonly observed in schizophrenia. However, a quantitative description of key sensorimotor components contributing to impaired dexterity is lacking. Whether the key components of dexterity are differentially affected and how they relate to clinical characteristics also remains unclear. We quantified the degree of dexterity in 35 stabilized patients with schizophrenia and in 20 age-matched control subjects using four visuomotor tasks: (i) force tracking to quantify visuomotor precision, (ii) sequential finger tapping to measure motor sequence recall, (iii) single-finger tapping to assess temporal regularity, and (iv) multi-finger tapping to measure independence of finger movements...

Superparamagnetic core-shell molecularly imprinted polymer nanoparticles (MIPs) were prepared via surface initiated reversible-addition fragmentation chain transfer (si-RAFT) polymerization for the selective recognition of 2,4-dichlorophenoxyacetic acid (2,4-D) in real samples. The construction of uniform core-shell structure with a 50nm MIP layer was successfully accomplished, which favored mass transfer and resulted in fast recognition kinetics. The static equilibrium experiments revealed the satisfied adsorption capacity and imprinting efficiency of Fe3O4@MIP...

It is highly desirable to screen for a large variety of organic compounds in water. Ultra-high performance liquid chromatography coupled to high-resolution mass spectrometry (UHPLC-HRMS) can analyse semi-polar to polar organic compounds in tap and mineral water. The use of UHPLC-HRMS is well consolidated for lipidomic, metabolomic and proteomic studies; based on the detection of a very large number of compounds of a variety of organic functions. Water analysis is usually performed by gas chromatography -mass spectrometry (GC-MS) techniques that are efficient for volatile organic compounds...
