Landmark retrieval is to return a set of images with their landmarks similar to those of the query images. Existing studies on landmark retrieval focus on exploiting the geometries of landmarks for visual similarity matches. However, the visual content of social images is of large diversity in many landmarks, and also some images share common patterns over different landmarks. On the other side, it has been observed that social images usually contain multimodal contents, i.e., visual content and text tags, and each landmark has the unique characteristic of both visual content and text content...

Drug dependence seems to involve a learning and memory process. Since learning and memory depend on protein synthesis, drug dependence may depend on protein synthesis, too. Drug-induced reward is a crucial effect for the development of drug-dependence. We used chloramphenicol (CAP, a protein synthesis inhibitor), to evaluate its effects on amphetamine (amph)-seeking behavior, on CB1R expression and on protein synthesis in general, in specific areas of the brain. Two groups of Wistar adult male rats were subjected to amph-induced conditioned place preference (CPP)...

Regular use of colorectal cancer screening can reduce incidence and mortality, but participation rates remain low among low-income, Spanish-speaking Latino adults. We conducted two distinct pilot studies testing the implementation of evidence-based interventions to promote fecal immunochemical test (FIT) screening among Latinos aged 50-75 years who were not up-to-date with CRC screening (n = 200) at a large Federally Qualified Health Center (FQHC) in San Diego, CA. One pilot focused on an opportunistic clinic visit "in-reach" intervention including a 30-min session with a patient navigator, review of an educational "flip-chart," and a take-home FIT kit with instructions...

BACKGROUND: In question answering (QA) system development, question classification is crucial for identifying information needs and improving the accuracy of returned answers. Although the questions are domain-specific, they are asked by non-professionals, making the question classification task more challenging. OBJECTIVE: This study aimed to classify health care-related questions posted by the general public (Chinese speakers) on the Internet. METHODS: A topic-based classification schema for health-related questions was built by manually annotating randomly selected questions...

Some animals learn to fear a situation after observing another individual come to harm, and this learning is influenced by the animals' social relationship and history. An important but sometimes overlooked factor in studies of observational fear learning is that social context not only affects observers, but may also influence the behavior and communications expressed by those being observed. Here we sought to investigate whether observational fear learning in the degu (Octodon degus) is affected by social familiarity, and the degree to which vocal expressions of alarm or distress contribute...

BACKGROUND: Cognitive deficits are a core feature of schizophrenia, and impairments in most domains are thought to be stable over the course of the illness. However, cross-sectional evidence indicates that some areas of cognition, such as visuospatial associative memory, may be preserved in the early stages of psychosis, but become impaired in later established illness stages. This longitudinal study investigated change in visuospatial and verbal associative memory following psychosis onset...

BACKGROUND: Surgical management of carpal tunnel syndrome (CTS) is performed with an open or endoscopic approach. Current literature suggests that the endoscopic approach is associated with higher costs and a steeper learning curve. This study evaluated the billing and utilization trends of both approaches. METHODS: A retrospective review of a Medicare database within the PearlDiver Supercomputer (Warsaw, IN) was performed for patients undergoing open carpal tunnel release (OCTR) or endoscopic carpal tunnel release (ECTR) from 2005-2012...

The hippocampus is important for both navigation and associative learning. We previously showed that the hippocampus processes two-dimensional (2D) landmarks and objects differently. Our findings suggested that landmarks are more likely to be used for orientation and navigation, whereas objects are more likely to be used for associative learning. The process by which cues are recognized as relevant for navigation or associative learning, however, is an open question. Presumably both spatial and nonspatial information are necessary for classifying cues as landmarks or objects...

In this first study of the impact of sleep on infants' problem solving of a locomotor task, 28 newly walking infants who were within a week of having given up crawling trained to navigate a shoulder-height tunnel to reach a caregiver waiting at the end. During the transitional window between crawling and walking, infants are reluctant to return to crawling, making this task uniquely challenging. Infants were randomly assigned to either nap or stay awake during a delay between training and a later test session...

The global supply of palliative care remains low, meeting 10% of current need. And if no changes are being made, with respect to attitudes, policies and funding towards palliative care, the problem will only worsen as global demand is set to increase with the changing demographics. The recognition of palliative care's potential to greatly improve one's quality of life while being an economical model of healthcare, is the first step that we must take internationally. That investment into palliative care will reap high returns...

BACKGROUND: Sri Lanka has been free from indigenous malaria since November 2012 and received the WHO certificate for malaria-free status in September 2016. Due to increased global travel, imported malaria cases continue to be reported in the country. Military personnel returning home from international peace-keeping missions in malaria endemic countries represent a key risk group in terms of imported malaria. The present study intended to characterize the potential causes of a malaria outbreak among the Sri Lankan security forces personnel deployed in the Central African Republic (CAR)...

Given the sheer number of drugs (over 20!) available for treatment of seizures, epilepsy can be considered one of the most successful areas in pharmaceutical development and especially for neuroscience. However, despite the large number of drug treatment options available for managing patients with epilepsy, there remains considerable unmet need. For example, the overall impact on seizure control has not been substantial with approximately 30% of patients remaining refractory or their seizures not adequately controlled...

Investments in preventing violence against children in the Asia and Pacific region will bring important social and economic returns that contribute to building the region's 'cognitive capital'. An analysis of burden of violence research in the region is presented to identify the impacts of violence and to demonstrate these returns. Violence is an everyday experience in the lives of many children in the Asia-Pacific, and the toxic stress associated with such routine forms of violence may permanently impact the architecture and chemistry of the developing brain...

Guest deaths are an inevitable aspect of the hospitality industry. In Study 1, participants read a vignette in which the previous guest died of natural causes, suicide, or homicide. Those who learned of a death (a) saw the room as less valuable, (b) opted to stay in a more basic room in which no death occurred, despite both rooms being offered for free, and (c) anticipated feeling uneasy when imagining an overnight stay. In Study 2, we investigated the persistence of this bias. Perceived room value and anticipatory well-being can be expected to return to baseline levels only many years after the death event...
