New analytical strategies tend to automation of sample pre-treatment and flow analysis techniques provided a number of enhanced analytical methods allowing high throughput. Flow techniques are usually faster, more robust and more flexible than their batch equivalents. In addition, flow methods use less sample and reagent amounts and reduce analytical costs and waste. A flow injection solid-phase extraction pre-concentration system using a molecularly imprinted polymer (MIP) packed micro-column was developed for the determination of 1-hydroxypyrene in human urine with fluorescence detection...

Sleep benefits the consolidation of individual episodic memories. In the long run, however, it may be more efficient to retain the abstract gist of single, related memories, which can be generalized to similar instances in the future. While episodic memory is enhanced after one night of sleep, effective gist abstraction is thought to require multiple nights. We tested this hypothesis using a visual Deese-Roediger-McDermott paradigm, examining gist abstraction and episodic-like memory consolidation after 20 min, after 10 hours, as well as after one year of retention...

PURPOSE: Despite the prevalence of oral disease, the subject of oral health historically has been absent from medical education. We have developed an interprofessional curriculum in collaboration with our school of dentistry to teach oral health in the primary care setting to physician assistant (PA) students. The goal was to create and assess the impact of a curricular model that would be adaptable to various academic settings. METHODS: A blend of classroom, clinical skills lab, observations in the dental clinic, and observed structured clinical examinations was used to teach oral health to first-year (didactic year) PA students...

BACKGROUND: CRISPR and CRISPR-flanking genomic regions are important for molecular epidemiology of Mycobacterium tuberculosis complex (MTBC) strains, and potentially for adaptive immunity to phage and plasmid DNA, and endogenous roles in the bacterium. Genotyping in the Israel National Mycobacterium Reference Center Tel-Aviv of over 1500 MTBC strains from 2008-2013 showed three strains with validated negative 43-spacer spoligotypes, that is, with putatively deleted direct repeat regions (deleted-DR/CRISPR regions)...

Retaining blood donors is a cost-effective way of ensuring a safe blood supply, yet despite the plethora of research, only 5.1% of the eligible population in Australia donate blood and 40% of these do not make a second donation. We offer an alternative to traditional approaches by conceptualizing blood donation within social representations theory as socially derived symbolic knowledge with a specific focus on cognitive polyphasia and Guimelli's (1998) normative and functional dimensions. An online survey, completed by 703 residents from NSW Australia, comprised a blood donation word association task, Likert-style questions constructed from previous word association data and contextualized blood donation statements...

BACKGROUND: Endoprostheses using principles of compressive osseointegration have shown good survivorship in several studies involving the lower extremity; however, no series to our knowledge have documented the use of this technology in the management of massive bone loss in the upper limb. QUESTIONS/PURPOSES: (1) What proportion of upper extremity implants using compressive osseointegration fixation principles achieved durable short-term fixation, and what were the modes of failure? (2) What surgical complications resulted from reconstruction using this technique? METHODS: A multiinstitutional retrospective review identified nine patients (five women; four men) who underwent 13 endoprosthetic replacements between 2003 and 2014 using compressive osseointegration (Compliant(®) Pre-stress Device [CPS]; Biomet Inc, Warsaw, IN, USA) in the upper extremity, including two proximal humeri, two humeral diaphyses, seven distal humeri, and two proximal ulna...

: A persistent challenge in enhancing gene therapy is the transient availability of the target gene product. This is particularly true in tissue engineering applications. The transient exposure of cells to the product could be insufficient to promote tissue regeneration. Here we report the development of a new material engineered to have a high affinity for a therapeutic gene product. We focus on insulin-like growth factor-I (IGF-I) for its highly anabolic effects on many tissues such as spinal cord, heart, brain and cartilage...

Plant proteinase inhibitor-II (PI-II) proteins are one of the promising defensive proteins that helped the plants to resist against different kinds of unfavorable conditions. Different roles for PI-II have been suggested such as regulation of endogenous proteases, modulation of plant growth and developmental processes and mediating stress responses. The basic knowledge on genetic and molecular diversity of these proteins has provided significant insight into their gene structure and evolutionary relationships in various members of this family...

BACKGROUND: Blood transfusion is an essential component of a modern healthcare system. Because knowledge about blood donor demography may inform the design of strategies for donor recruitment and retention, we used nationwide registers to characterize the entire population of blood donors in Denmark in 2010. METHODS: The study population comprised all Danes in the age range eligible for blood donation (N = 3,236,753) at the end of 2010. From the Scandinavian Donations and Transfusions (SCANDAT) register, we identified 174,523 persons who donated blood in Danish blood banks at least once in 2010...

BACKGROUND/AIMS: Trust is the cornerstone of clinical trial recruitment and retention. Efforts to decrease barriers and increase clinical trial participation among diverse populations have yielded modest results. There is an urgent need to better understand the complex interactions between trust and clinical trial participation. The process of trust-building has been a focus of intense research in the business community. Yet, little has been published about trust in oncology clinical trials or the process of building trust in clinical trials...

PURPOSE: To assess whether provision of a personalized patient-held eye health summary (glaucoma personal record) improves patients' knowledge of glaucoma at 1-year follow-up. The National Institute for Clinical Excellence has recommended such an approach to ascertain if this may ultimately help slow disease progression. METHODS: Recruited patients, newly diagnosed with glaucoma conditions, were randomly allocated to receive standard clinical care or an additional glaucoma personal record, detailing the current state of each individual's eye condition...

Hashimoto's Encephalopathy (HE) is a rare form of autoimmune encephalopathy associated with Hashimoto's thyroiditis in which patients experience cognitive impairment and various neurologic symptoms. We present a case of a young female that presented to the emergency department with urinary retention, and was ultimately diagnosed with HE. Examination was significant for direction-changing and vertical nystagmus (direction-changing nystagmus describes a phenomenon where the fast beat changes with the direction of gaze), hyperreflexia, clonus, and Babinski and Hoffman's reflexes (all upper motor neuron (UMN) signs)...

We previously demonstrated that a pediatric cardiology boot camp can improve knowledge acquisition and decrease anxiety for trainees. We sought to determine if boot camp participants entered fellowship with a knowledge advantage over fellows who did not attend and if there was moderate-term retention of that knowledge. A 2-day training program was provided for incoming pediatric cardiology fellows from eight fellowship programs in April 2016. Hands-on, immersive experiences and simulations were provided in all major areas of pediatric cardiology...

: β-amyloid (Aβ) peptides play a key role in synaptic damage and memory deficits in the early pathogenesis of Alzheimer's disease (AD). Abnormal accumulation of Aβ at nerve terminals leads to synaptic pathology and ultimately to neurodegeneration. β-site amyloid precursor protein (APP) cleaving enzyme 1 (BACE1) is the major neuronal β-secretase for Aβ generation. However, the mechanisms regulating BACE1 distribution in axons and β cleavage of APP at synapses remain largely unknown...

BACKGROUND: Present knowledge indicates a multilayered hierarchical gene regulatory network (ML-hGRN) often operates above a biological pathway. Although the ML-hGRN is very important for understanding how a pathway is regulated, there is almost no computational algorithm for directly constructing ML-hGRNs. RESULTS: A backward elimination random forest (BWERF) algorithm was developed for constructing the ML-hGRN operating above a biological pathway. For each pathway gene, the BWERF used a random forest model to calculate the importance values of all transcription factors (TFs) to this pathway gene recursively with a portion (e...
