Sulfite oxidases are metalloenzymes that oxidize sulfite to sulfate at a molybdenum active site. In vertebrate sulfite oxidases, the electrons generated at the Mo center are transferred to an external electron acceptor via a heme domain, which can adopt two conformations: a "closed" conformation, suitable for internal electron transfer, and an "open" conformation suitable for intermolecular electron transfer. This conformational change is an integral part of the catalytic cycle. Sulfite oxidases have been wired to electrode surfaces, but their immobilization lead to a significant decrease in their catalytic activity, raising the question of the occurrence of the conformational change when the enzyme is on an electrode...

For primary open angle glaucoma (POAG), laser treatment or surgery is used when the target intraocular pressure (IOP) cannot be achieved by pharmacological agents, such as prostaglandin (PG) analogs; these drugs also have varied effects. We retrospectively reviewed the medical records of 74 POAG patients (74 eyes) whose IOP was inadequately controlled by PG analogs (bimatoprost [13 eyes], latanoprost [34 eyes], tafluprost [11 eyes], and travoprost [16 eyes]) and underwent primary trabeculectomy. The proportion of patients with no recurrent IOP elevation within 24 months post-trabeculectomy was significantly (P < 0...

In tonal languages, such as Mandarin Chinese, the pitch contour of vowels discriminates lexical meaning, which is not the case in non-tonal languages such as German. Recent data provide evidence that pitch processing is influenced by language experience. However, there are still many open questions concerning the representation of such phonological and language-related differences at the level of the auditory cortex (AC). Using magnetoencephalography (MEG), we recorded transient and sustained auditory evoked fields (AEF) in native Chinese and German speakers to investigate language related phonological and semantic aspects in the processing of acoustic stimuli...

BACKGROUND: Over the last decade, robotic approaches have been described for removing adrenal tumors. Although there are reports comparing robotic and laparoscopic techniques in general, there are limited data on outcomes in patients with primary hyperaldosteronism (PHA). The aim of this study is to compare the safety and efficacy of robotic adrenalectomy (RA) versus laparoscopic adrenalectomy (LA) for PHA. MATERIALS AND METHODS: The records of 20 patients who underwent RA for PHA were compared with 16 patients who underwent LA between 2000 and 2014...

Chronic wounds (VLU: venous leg ulcer, DFU: diabetic foot ulcer, PU: pressure ulcer, or complex wounds) affect a significant proportion of the population. Despite appropriate standard wound care, such ulcers unfortunately may remain open for months or even years. The use of leukocyte- and platelet-rich fibrin (L-PRF) to cure skin ulcers is a simple and inexpensive method, widely used in some countries but unknown or neglected in most others. This auto-controlled prospective cohort study explored and quantified accurately for the first time the adjunctive benefits of topical applications of L-PRF in the management of such refractory ulcers in a diverse group of patients...

Introduction  Treatment of unstable distal radial fractures (DRFs) in elderly patients is controversial, and considering the increasing life expectancy, their appropriate treatment is of growing importance. Our aim was to analyze the clinical and radiologic outcomes in the elderly patients with AO type C DRF treated with volar locking plate (VLP). Materials and Methods  Between 2007 and 2011, 572 DRFs were operated on in our hospital with open reduction and internal fixation with VLP. Of these, only 64 patients (66 DRFs) met the selection criteria (AO type C DRF, age > 70 years, minimum 12-month follow-up)...

The introduction of animal-borne, multisensor tags has opened up many opportunities for ecological research, making previously inaccessible species and behaviors observable. The advancement of tag technology and the increasingly widespread use of bio-logging tags are leading to large volumes of sometimes extremely detailed data. With the increasing quantity and duration of tag deployments, a set of tools needs to be developed to aid in facilitating and standardizing the analysis of movement sensor data. Here, we developed an observation-based decision tree method to detect feeding events in data from multisensor movement tags attached to fin whales (Balaenoptera physalus)...

Climate warming is predicted to affect species and trophic interactions worldwide, and alpine ecosystems are expected to be especially sensitive to changes. In this study, we used two ongoing climate warming (open-top chambers) experiments at Finse, southern Norway, to examine whether warming had an effect on herbivory by leaf-chewing insects in an alpine Dryas heath community. We recorded feeding marks on the most common vascular plant species in warmed and control plots at two experimental sites at different elevations and carried out a brief inventory of insect herbivores...

The impairment of orofacial motor function during orthodontic treatment is need to be addressed, since most of orthodontic patients experience pain and motor excitability would be affected by pain. In the present study, the temporal alteration of the jaw-opening reflex excitability was investigated to determine if orthodontic treatment affects orofacial motor function. The excitability of jaw-opening reflex evoked by electrical stimulation on the gingiva and recorded bilaterally in the anterior digastric muscles was evaluated at one (D1), three (D3) and seven (D7) days after orthodontic force application to the teeth of right side, morphological features (e...

Safety pharmacology studies in dogs often integrate behavioral assessments made using video recording with physiologic measurements collected by telemetry. However, whether merely wearing the telemetry vest affects canine behavior and other parameters has not been evaluated. This pilot study assessed the effect of a telemetry vest on behavioral and physiologic responses to an environmental stressor, the sounds of a thunderstorm, in Labrador retrievers. Dogs were assigned to one of 2 experimental groups (Vest and No-Vest, n = 8 dogs per group) by using a matched pairs design, with a previously determined, sound-associated anxiety score as the blocking variable...

Upon thermal annealing at or above room temperature (RT) and at high hydrostatic pressure <i>P</i> ~ 155 GPa, sulfur trihydride H<sub>3</sub>S exhibits a measured maximum superconducting transition temperature <i>T</i><sub>C</sub> ~ 200 K. Various theoretical frameworks incorporating strong electron-phonon coupling and Coulomb repulsion have reproduced this record-level <i>T</i><sub>C</sub>. Of particular relevance is that experimentally observed H-D isotopic correlations among <i>T</i><sub>C</sub>, <i>P</i>, and annealed order indicate an H-D isotope effect exponent α limited to values ≤ 0...
