Proteins are the macromolecules responsible for almost all biological processes in a cell. With the availability of large number of protein sequences from different sequencing projects, the challenge with the scientist is to characterize their functions. As the wet lab methods are time consuming and expensive, many computational methods such as FASTA, PSI-BLAST, DNA microarray clustering, and Nearest Neighborhood classification on protein-protein interaction network have been proposed. Support vector machine is one such method that has been used successfully for several problems such as protein fold recognition, protein structure prediction etc...

China's aquaculture industry is growing dramatically in recent years and now accounts for 60.5% of global aquaculture production. Fish protein is expected to play an important role in China's food security. Formulated feed has become the main diet of farmed fish. The species farmed have been diversified, and a large amount of 'trash fish' is directly used as feed or is processed into fishmeal for fish feed. The use of locally available food waste as an alternative protein source for producing fish feed has been suggested as a means of tackling the problem of sourcing safe and sustainable feed...

New productive niches can offer new commercial perspectives linked to donkeys' products and human therapeutic or leisure applications. However, no assessment for selection criteria has been carried out yet. First, we assessed the animal inherent features and environmental factors that may potentially influence several cognitive processes in donkeys. Then, we aimed at describing a practical methodology to quantify such cognitive processes, seeking their inclusion in breeding and conservation programmes, through a multifactorial linear model...

Judith M Harackiewicz, Stacy J Priniski
Many theoretically based interventions have been developed over the past two decades to improve educational outcomes in higher education. Based in social-psychological and motivation theories, well-crafted interventions have proven remarkably effective because they target specific educational problems and the processes that underlie them. In this review, we evaluate the current state of the literature on targeted interventions in higher education with an eye to emerging theoretical and conceptual questions about intervention science...

Research into the problem of splice site selection has followed a reductionist approach focused on how individual splice sites are recognized. Early applications of information theory uncovered an inconsistency. Human splice signals do not contain enough information to explain the observed fidelity of splicing. Here, we conclude that introns do not necessarily contain 'missing' information but rather may require definition from neighboring processing events. For example, there are known cases where an intronic mutation disrupts the splicing of not only the local intron but also adjacent introns...

Advances in high throughput sequencing technologies have created a gap between data production and functional data analysis. Indeed, phenotypes result from interactions between numerous genes, but traditional methods treat loci independently, missing important knowledge brought by network-level emerging properties. Therefore, detecting selection acting on multiple genes affecting the evolution of complex traits remains challenging. In this context, gene network analysis provides a powerful framework to study the evolution of adaptive traits and facilitates the interpretation of genome-wide data...

Sue Barker, Mary Lynch, Jane Hopkinson
BACKGROUND: There are an increasing number of people living with dementia, as well as an expectation that care decisions are made collaboratively with those with the disease entering the end stage and their families. This has increased the burden on family carers. AIM: To explore the evidence on the decisional support needs of informal carers of people with end-stage dementia. DESIGN: A rapid scoping review was undertaken of peer-reviewed publications between 2000 and 2016, which included all health-care settings and the person's own home...

Chunliang Yang, David R Shanks
Induction refers to the process in which people generalize their previous experience when making uncertain inferences about the environment that go beyond direct experience. Here we show that interim tests strongly enhance inductive learning. Participants studied the painting styles of eight famous artists across four lists, each comprising paintings by one pair of artists. In an interim test group participants' induction was tested after each list. In two control groups participants solved math problems (interim math group) or studied additional new paintings (interim study group) following each of Lists 1-3 and were asked to classify new paintings on List 4...

Child sleep problems are associated with maternal depressive symptoms. It is unclear to what extent the association is due to direct effects or common risk factors for mother and child. Direct effects could represent child-driven processes, where child sleep problems influence maternal depressive symptoms, or mother-driven processes, where maternal depressive symptoms influence child sleep problems. Common factors could be shared genetic and familial environmental risk. Child- and mother-driven processes are direct in the sense that they are not due to common factors...

Although protein-protein interactions (PPIs) have crucial roles in virtually all cellular processes, the identification of more transient interactions in their biological context remains challenging. Conventional photo-cross-linking strategies can be used to identify transient interactions, but these approaches often suffer from high background due to the cross-linked bait proteins. To solve the problem, we have developed membrane-permeable releasable photo-cross-linkers that allow for prey-bait separation after protein complex isolation and can be installed in proteins of interest (POIs) as unnatural amino acids...

In recent years, there is a rising interest in the number of food products containing probiotic bacteria with favorable health benefit effects. However, the viability of probiotic bacteria is always questionable when they exposure to the harsh environment during processing, storage and gastrointestinal digestion. To overcome these problems, microencapsulation of cells is currently receiving considerable attention and has obtained valuable effects. According to the drying temperature, the commonly used technologies can be divided into two patterns: high temperature drying (spray drying, fluid bed drying) and low temperature drying (ultrasonic vacuum spray drying, spray chilling, electrospinning, supercritical technique, freeze drying, extrusion, emulsion, enzyme gelation and impinging aerosol technique)...

Qian Wang, Yining Zhu, Hengyong Yu
Dual spectral computed tomography (DSCT) has a superior material distinguishability than the conventional single spectral computed tomography (SSCT). However, the decomposition process is an illposed problem, which is sensitive to noise. Thus, the decomposed image quality is degraded, and the corresponding signal-to-noise ratio (SNR) is much lower than that of directly reconstructed image of SSCT. In this work, we establish a locally linear relationship between the decomposed results of DSCT and SSCT. Based on this constraint, we propose an optimization model for DSCT and develop an iterative method with image guided filtering...

The main tackle of cancer treatment is multidrug resistance during chemotherapy. Cancer cell can evade cell death during every round of orthodox chemotherapy drugs, consequently being resistance after several rounds of standard drug treatment. One of the regimens to address this multidrug resistance problem is by drug combination. However, synthetic drugs always have problems of strong side effects and toxicity. Natural compounds deriving from traditional Chinese medicine are known to have low toxicity and genuine promising effects in reversing multidrug resistance, either induced by orthodox chemotherapeutic or targeted therapy drugs...

Natural products with complex and diverse structures are the major sources of new drugs. The biosynthesis of natural products is considered to be one of the best ways to solve the problems of complex and scarce natural products. DNA assembly technology and genome editing technology are two key technologies in the emerging interdisciplinary field of synthetic biology. A number of novel DNA assembly methods developed in the last few years have paved the way for the engineering of high molecular weight DNA molecules, including whole genomes, hence, it can realize the reconstruction of the metabolic pathways and speed up optimization process...

BACKGROUND: Lung cancer is increasingly a disease of the elderly and frail population with a median age of 70 years at diagnosis. Therefore, consideration of the impact of interventions on health-related quality of life (HRQOL) and not only absolute survival is especially important. For non-small cell lung cancer (NSCLC), video-assisted thoracoscopic surgery (VATS) has been gaining popularity over the last few decades, replacing traditional open lobectomies. For high-risk patients who are not deemed suitable for surgery, stereotactic ablative body radiotherapy (SABR) provides a potentially curative alternative...

Complement activation is largely implicated in the pathogenesis of several clinical conditions and its therapeutic neutralization has proven effective in preventing tissue and organ damage. A problem that still needs to be solved in the therapeutic control of complement-mediated diseases is how to avoid side effects associated with chronic neutralization of the complement system, in particular, the increased risk of infections. We addressed this issue developing a strategy based on the preferential delivery of a C5 complement inhibitor to the organ involved in the pathologic process...

REVIEW
Jitendra Mishra, Rachna Singh, Naveen K Arora
Increasing concentration of heavy metals (HM) due to various anthropogenic activities is a serious problem. Plants are very much affected by HM pollution particularly in contaminated soils. Survival of plants becomes tough and its overall health under HM stress is impaired. Remediation of HM in contaminated soil is done by physical and chemical processes which are costly, time-consuming, and non-sustainable. Metal-microbe interaction is an emerging but under-utilized technology that can be exploited to reduce HM stress in plants...

BACKGROUND: The nursing process is a systematic method of planning, delivering, and evaluating individualized care for clients in any state of health or illness. Many countries have adopted the nursing process as the standard of care to guide nursing practice; however, the problem is its implementation. If nurses fail to carry out the necessary nursing care through the nursing process; the effectiveness of patient progress may be compromised and can lead to preventable adverse events...
