In many complicated cognitive-motor tasks mentoring is inevitable during the learning process. Although mentors are expert in doing the task, trainee's operation might be new for a mentor. This makes mentoring a very difficult task which demands not only the knowledge and experience of a mentor, but also his/her ability to follow trainee's movements and patiently advise him/her during the operation. We hypothesize that information binding throughout the mentor's brain areas, contributed to the task, changes as the expertise level of the trainee improves from novice to intermediate and expert...

Learning a new motor skill involves multiple cognitive aspects such as attention, planning, prioritizing, execution, and error correction. In current study, we examined whether the students opted for pure mathematics at their undergraduate level have enhanced motor skills as compared to those pursuing biological sciences at the same level of education. A total of twenty subjects participated in a visuomotor adaptation task. The results showed that the overall movement related errors in subjects with mathematics background were lower than the biosciences students (p = 0...

A wirelessly powered implantable device is proposed for fully programmable and localized drug delivery. The implant is powered using an external ultrasonic transmitter and operates at <; 5% of the FDA diagnostic ultrasound intensity limit. Drug release is achieved through electrical stimulation of drug-loaded polypyrrole nanoparticles. A design methodology for the implant electronics is presented and experimentally demonstrated to be accurate in predicting the concentration of the released drug. To the best of our knowledge, this is the first ultrasonically powered implantable device platform for targeted drug delivery using electroresponsive polymers...

Significant progress has been made in recent years for computer-aided diagnosis of abnormal pulmonary textures from computed tomography (CT) images. Similar initiatives in chest radiographs (CXR), the common modality for pulmonary diagnosis, are much less developed. CXR are fast, cost effective and low-radiation solution to diagnosis over CT. However, the subtlety of textures in CXR makes them hard to discern even by trained eye. We explore the performance of deep learning abnormal tissue characterization from CXR...

Lacosamide (LCM) due to no known drug interaction and the absence of metabolic enzyme induction is a good candidate for an add-on medication, especially in combination with lamotrigine, levetiracetam (LEV), oxcarbazepine, topiramate, and valproic acid (VPA). Here we report for the first time, to our knowledge, that LCM can lower VPA and LEV serum levels. At present, there are no known explicable mechanisms of action of LCM, which lowers VPA and LEV. Here observed drug interaction of LCM is of clinical significance, which might be useful for other colleagues in the field...

As the number of speech-language pathologists (SLPs) responsible for swallowing and feeding services in the educational setting increases, guidance informing this specialized practice continues to emerge. Although SLPs have provided dysphagia management for children in medical settings for many years, the extension of dysphagia services to the schools is comparatively new. This shift in care delivery for what was previously a hospital-based practice is now occurring more frequently, and in an environment void of extensive medical supports (i...

Zimin Zhao, Cherie Paquette, Akeesha A Shah, Kristen A Atkins, Henry F Frierson
BACKGROUND: Tenosynovial giant cell tumor (TSGCT), also known as giant cell tumor of tendon sheath or pigmented villonodular synovitis, is the most common benign tumor of the tendon and synovium. The intra-articular diffuse type can present as a large infiltrative mass involving adjacent soft tissue and sometimes causes secondary destruction of bone, which leads to radiographic and clinical concern for malignancy. The tumor may also be purely extra-articular. CASE: Here, we report the fine needle aspiration cytology findings of 2 cases of diffuse-type TSGCT with large mononuclear cells with eccentric nuclei, finely granular cytoplasm, and a peripheral well-defined cytoplasmic rim of hemosiderin ("ladybird cells")...

Groundwater management in urban areas requires a detailed knowledge of the hydrogeological system as well as the adequate tools for predicting the amount of groundwater and water quality evolution. In that context, a key difference between urban and natural areas lies in recharge evaluation. A large number of studies have been published since the 1990s that evaluate recharge in urban areas, with no specific methodology. Most of these methods show that there are generally higher rates of recharge in urban settings than in natural settings...

The rapid development of time-series data mining provides an emerging method for water resource management research. In this paper, based on the time-series data mining methodology, we propose a novel and general analysis framework for water quality time-series data. It consists of two parts: implementation components and common tasks of time-series data mining in water quality data. In the first part, we propose to granulate the time series into several two-dimensional normal clouds and calculate the similarities in the granulated level...

OBJECTIVES: Traumatic Brain Injury (TBI) is a common and debilitating injury that is particularly prevalent in patients over 60. Given the influence of head injury on dementia (and vice versa), and the increased likelihood of ground-level falls, elderly patients are vulnerable to TBI. Educational interventions can increase knowledge and influence preventative activity to decrease the likelihood of further TBI. We sought to determine the efficacy of interactive tablet-based educational interventions in elderly patients on self-reported knowledge...

Wetlands are important ecosystems characterized by redoximorphic environments producing typical soil forming processes and organic carbon accumulation. Assessments and management of these areas are dependent on knowledge about soil characteristics and variability. By reflectance spectroscopy, information about soils can be obtained since their spectral behaviors are directly related to their chemical, physical, and mineralogical properties reflecting the pedogenetic processes and environment conditions. Our aims were: (a) to characterize the main soil classes of wetlands regarding their spectral behaviors in VIS-NIR-SWIR (350-2500 nm) and relate them to pedogenesis and environmental conditions, (b) to determine spectral ranges (bands) with greater expression of the main soil properties, (c) to identify spectral variations and similarities between hydromorphic soils from wetlands and other soils under different moisture conditions, and (d) to propose spectral models to quantify some chemical and physical soil properties used as environmental quality indicators...

Substrate limitation occurs frequently in wastewater treatment and knowledge about microbial behavior at limiting conditions is essential for the use of biokinetic models in system design and optimization. Monod kinetics are well-accepted for modeling growth rates when a single substrate is limiting, but several models exist for treating two or more limiting substrates simultaneously. In this study three dual limitation models (multiplicative, minimum, and Bertolazzi) were compared based on experiments using nitrite-oxidizing bacteria (limited by dissolved oxygen and nitrite) and ANaerobic AMMonia-OXidizing bacteria or Aanammox (limited by ammonium and nitrite) within mixed liquor from deammonification pilots...

The extraction of patterns in the environment plays a critical role in many types of human learning, from motor skills to language acquisition. This process is known as statistical learning. Here we propose that statistical learning has two dissociable components: (1) perceptual binding of individual stimulus units into integrated composites and (2) storing those integrated representations for later use. Statistical learning is typically assessed using post-learning tasks, such that the two components are conflated...

Bone homeostasis depends on the resorption of bones by osteoclasts and formation of bones by the osteoblasts. Imbalance of this tightly coupled process can cause diseases such as osteoporosis. Thus, the mechanisms that regulate communication between osteoclasts and osteoblasts are critical to bone cell biology. It has been shown that osteoblasts and osteoclasts can communicate with each other through direct cell-cell contact, cytokines, and extracellular matrix interaction. Osteoblasts can affect osteoclast formation, differentiation, or apoptosis through several pathways, such as OPG/RANKL/RANK, RANKL/LGR4/RANK, Ephrin2/ephB4, and Fas/FasL pathways...

The knowledge of pharmacokinetic and pharmacodynamic properties of antiepileptic drugs is helpful in optimizing drug therapy for epilepsy. This study was designed to evaluate the pharmacokinetic and pharmacodynamic properties of lacosamide in experimentally induced hepatic and renal impairment in seizure animals. Hepatic or renal impairment was induced by injection of carbon tetrachloride or diclofenac sodium, respectively. After induction, the animals were administered with a single dose of lacosamide. At different time points, MES seizure recordings were done followed by isolation of plasma and brain samples for drug quantification and pharmacodynamic measurements...
