INTRODUCTION: (111)In-DTPA-d-Phe(1)-octreotide scintigraphy is an important method of detecting neuroendocrine tumors. We previously reported that a new derivative of (111)In-DTPA-d-Phe(1)-octreotide, (111)In-DTPA-d-Phe(-1)-Asp(0)-d-Phe(1)-octreotide, accomplished the reduction of prolonged renal accumulation of radioactivity. The aim of this study was to evaluate the tumor accumulation of (111)In-DTPA-d-Phe(-1)-Asp(0)-d-Phe(1)-octreotide in vitro and in vivo by comparing it with (111)In-DTPA-d-Phe(1)-octreotide...

OBJECTIVE To date, treatment of complex unruptured intracranial aneurysms (UIAs) remains challenging. Therefore, advanced techniques are required to achieve an optimal result in treating these patients safely. In this study, the safety and efficacy of rapid ventricular pacing (RVP) to facilitate microsurgical clip reconstruction was investigated prospectively in a joined neurosurgery, anesthesiology, and cardiology study. METHODS Patients with complex UIAs were prospectively enrolled. Both the safety and efficacy of RVP were evaluated by recording cardiovascular events and outcomes of patients as well as the amount of aneurysm occlusion after the surgical clip reconstruction procedure...

BACKGROUND: Type 1 diabetes mellitus described as a chronic metabolic disorder characterized by aggressive immune β-cell destruction. There are numbers of varied immune mechanisms for sustaining self-tolerance in opposition to the autoimmune disorders. A recessive tolerance accomplished by thymic gland via a negative assortment of different clones while a dominant tolerance accomplished by the regulatory T cells (Treg) in the periphery. Treg (CD4+CD25+FOXP3+) are subsets of T cells which have an essential role in maintaining tolerance...

With the global temperature change, plant adaptations are predicted, but little is known about the molecular mechanisms underlying them. Arabidopsis thaliana is a model plant adapted to various environmental conditions, in particular able to develop along an altitudinal gradient. Two ecotypes, Columbia (Col) growing at low altitude, and Shahdara (Sha) growing at 3400m, have been studied at optimal and sub-optimal growth temperature (22°C vs 15°C). Macro- and micro-phenotyping, cell wall monosaccharides analyses, cell wall proteomics, and transcriptomics have been performed in order to accomplish an integrative analysis...

A visible light-induced monochlorination of cyclohexane with sodium chloride (5:1) has been successfully accomplished to afford chlorocyclohexane in excellent yield by using Oxone as the oxidant in H2O/CF3CH2OH at room temperature. Other secondary and primary alkyl sp(3) C-H bonds of cycloalkanes and functional branch/linear alkanes can also be chlorinated, respectively, under similar conditions. The selection of a suitable organic solvent is crucial in these efficient radical chlorinations of alkanes in two-phase solutions...

A practical and straightforward synthetic route through a selectfluor-triggered tandem cyclization of o-hydroxyarylenaminone was developed to construct a variety of difluorinated 2-amino-substituted chromanones. This novel protocol features mild reaction conditions, operational simplicity, and broad substrate scope. The enamine moiety in o-hydroxyarylenaminone played dual roles to enable high efficiency in the difluorination and intramolecular cyclization, leading to the accomplishment of new class of difluorinated 2-amino-substituted chromanones for pharmaceutical studies...

OBJECTIVES: Lactation is the most energy-demanding phase of reproduction for human females, but it is still unclear how women in different environments are able to meet this additional energy demand. Previous studies have investigated whether changes in metabolism could have an energy-sparing effect in lactation, with conflicting results. Here, we asked whether increased energy efficiency in physical activity serves as an energy-sparing mechanism in lactation. METHODS: We used a longitudinal design with a control group...

Imitation is a cornerstone of human development, serving both a cognitive function (e.g. in the acquisition and transmission of skills and knowledge) and a social-communicative function, whereby the imitation of familiar actions serves to maintain social interaction and promote prosociality. In nonhuman primates, this latter function is poorly understood, or even claimed to be absent. In this observational study, we documented interactions between chimpanzees and zoo visitors and found that the two species imitated each other at a similar rate, corresponding to almost 10% of all produced actions...

BACKGROUND: Patients with upper third esophageal cancer or esophageal cancer with upper mediastinal paratracheal lymph node metastases are often precluded from surgery because of technical difficulties. With the aid of robotic surgery, an excellent overview and reach of the thoracic inlet can be accomplished. In this way, patients with upper mediastinal esophageal cancer are eligible for esophageal resection with curative intent. The aim of this study was to review the results of a consecutive series of patients who underwent robot-assisted minimally invasive esophagectomy (RAMIE) for tumors of the upper 1/3 of the esophagus or positive lymph nodes in the upper mediastinum...

A positive training synergy can be obtained when two individuals attempt to learn the same motor task while mechanically coupled to one another. In this paper, we have studied how mimicking this interaction through impedance control can be exploited to improve assistance delivered by hand exoskeleton devices during rehabilitation. In this context, the machine and user take complementary roles akin to two coupled individuals. We present the derivation of a dynamic model of the human hand for the purpose of controller development for new hand exoskeleton platforms...

The past decade has seen the emergence of rehabilitation treatments using virtual reality environments. One of the advantages in using this technology is the potential to create positive motivation, by means of engaging environments and tasks shaped in the form of serious games. In this work, we propose a novel Neuro Rehabilitation System for children with movement disorders, that is based on serious games in immersive virtual reality with haptic feedback. The system design aims to enhance involvement and engagement of patients, to provide congruent multi-sensory afferent feedback during motor exercises, and to benefit from the flexibility of virtual reality in adapting exercises to the patient's needs...

People with a high level of disability experience great difficulties to perform activities of daily living and resort to their residual motor functions in order to operate assistive devices. The commercially available interfaces used to control assistive manipulators are typically based on joysticks and can be used only by subjects with upper-limb residual mobilities. Many other solutions can be found in the literature, based on the use of multiple sensory systems for detecting the human motion intention and state...

This study explores the use of isometric movement training for arm rehabilitation after stroke. The aim of this approach is to enhance movement skill even when the person training is not moving. This is accomplished by deceptively displaying virtual motions, exploiting known cross-modal sensory interactions between vision and proprioception. This approach can be advantageous in situations where actual movement is prohibitive due to weakness, spasticity, instability, or unsafe conditions. We present early insights on usability of and tolerance to this training approach and quantitative results that can power future clinical trials...

Global change, such as warming and ocean acidification, and local anthropogenic disturbances, such as eutrophication, can have profound impacts on marine organisms. However, we are far from being able to predict the outcome of multiple interacting disturbances on seagrass communities. Herbivores are key in determining plant community structure and the transfer of energy up the food web. Global and local disturbances may alter the ecological role of herbivory by modifying leaf palatability (i.e. leaf traits) and consequently, the feeding patterns of herbivores...

The influence of electrical excess charges on the crystallization from supersaturated aqueous sodium chloride solutions is reported. This is accomplished by efflorescence studies on single levitated microdroplets using optical and electrodynamic levitation. Specifically, a strong increase in efflorescence humidity is observed as a function of the droplet's negative excess charge, ranging up to -2.1 pC, with a distinct threshold behavior, increasing the relative efflorescence humidity, at which spontaneous nucleation occurs, from 44% for the neutral microparticle to 60%...
