Limited attention has been paid to the effect of dietary patterns on sleep problems. In the present study, we analyzed the cross-sectional data of 481,242 adults aged 30-79 years from the China Kadoorie Biobank. A laptop-based questionnaire was administered to collect information on food intakes and insomnia symptoms. Logistic regression was used to estimate the odds ratios of each insomnia symptom according to quartiles of each dietary pattern, with adjustment for potential confounders. Two major dietary patterns were derived by factor analysis...

Summary: Current synteny visualization tools either focus on small regions of sequence and do not illustrate genome-wide trends, or are complicated to use and create visualizations that are difficult to interpret. To address this challenge, The Comparative Genomics Platform (CoGe) has developed two web-based tools to visualize synteny across whole genomes. SynMap2 and SynMap3D allow researchers to explore whole genome synteny patterns (across two or three genomes, respectively) in responsive, web-based visualization and virtual reality environments...

Background and Aims: Inflammatory bowel disease (IBD) patients are still under-diagnosed or diagnosed with serious delay. We examined whether diagnostic delay (DD) in IBD has changed over the last 60 years, and explored the risk factors of longer DD. Methods: 3392 IBD patients recorded in the registry of four IBD Italian centres were divided according to the year of diagnosis into a historical cohort (HC: 1955-1984) and modern cohort (MC: 1985-2014). DD, i.e. time lapse between onset of symptoms indicative of IBD and definitive diagnosis, was divided into four sub-periods (0-6, 7-12, 13-24, >24 months) which were correlated with age and disease location/behaviour at diagnosis...

Appropriate large-scale citizen-science data present important new opportunities for biodiversity modelling, due in part to the wide spatial coverage of information. Recently proposed occupancy modelling approaches naturally incorporate random effects in order to account for annual variation in the composition of sites surveyed. In turn this leads to Bayesian analysis and model fitting, which are typically extremely time consuming. Motivated by presence-only records of occurrence from the UK Butterflies for the New Millennium data base, we present an alternative approach, in which site variation is described in a standard way through logistic regression on relevant environmental covariates...

BACKGROUND: Disability either due to illness, aging, or both causes remains an essential contributor shaping European labor markets. Ability of modern day welfare states to compensate an impaired work ability and absenteeism arising from incapacity is very diverse. The aims of this study were to establish and explain intercountry differences among selected European OECD countries and to provide forecasts of future work absenteeism and expenditures on wage replacement benefits. METHODS: Two major public registries, European health for all database and Organization for Economic Co-operation and Development database (OECD Health Data), were coupled to form a joint database on 12 core indicators...

Animal venom research is a specialized investigation field, in which a number of different methods are used and this array is constantly expanding. Thus, recently emerged omics and nanotechnologies have already been successfully applied to venom research. Animal venoms have been studied for quite a long time. The traditional reductionist approach has been to isolate individual toxins and then study their structure and function. Unfortunately, the characterization of the venom as a whole system and its multiple effects on an entire organism were not possible until recent times...

Land and sea surface temperatures, precipitation, and storm tracks in North America and the North Pacific are controlled to a large degree by atmospheric variability associated with the Pacific North American (PNA) pattern. The modern instrumental record indicates a trend toward a positive PNA phase in recent decades, which has led to accelerated warming and snowpack decline in northwestern North America. The brevity of the instrumental record, however, limits our understanding of long-term PNA variability and its directional or cyclic patterns...

BACKGROUND: Independent risk factors such as age, loss of consciousness, elevated serum creatinine, low haemoglobin and ECG evidence of ischemia have previously been shown to predict mortality after ruptured abdominal aortic aneurysm (rAAA). With an ageing Australian population, we sought to determine if patients presenting with rAAA now had more predictive risk factors for mortality, and whether these factors remain predictive of mortality. METHODS: The records of all patients presenting with rAAA between January 1985 to December 1993 (past era, group 1) and January 2007 to December 2011 (modern era, group 2) were retrieved...

BACKGROUND: Burns present a devastating injury to patients. Burns caused by chemical agents, present a worse scenario. In a resource limited country like Nigeria, readily available sources of these corrosive agents are mainly from lead-acid battery vendors and to some extent local small scale soap manufacturers who use caustic soda. We hypothesized that with the reduction in small scale soap manufacturing and increasing trend towards modernization in the use of dry cell batteries, chemical burns may be on the decline, and we sought to investigate this...

Treatment for locally advanced rectal cancer has evolved from surgery alone to surgery plus adjuvant therapy. Preoperative 5-fluorouracil- or capecitabine-based chemoradiation with standard fractionated radiation, surgery utilizing total mesorectal excision, and further chemotherapy has become the standard of care in the USA. Preoperative adjuvant chemoradiation treatment sequencing has allowed for decreased toxicity, more sphincter-sparing surgery, and improved local control rates as compared to delivering the chemoradiation postoperatively...

Conventional dressings are cost-effective and highly absorbent, but not effectual enough to promote hemostasis, adherence and in holding a moist wound bed. Thanks to the developments in the field of nanotechnology and bioengineering, one of the promising current trends is to move progress of innovative wound dressings, merging the application of traditional healing agents and modern products/practices, such as hydrocolloids, hydrogels, films and nanofibers. The electrospun nanofibers webs can provide the essential parameters require for wound dressing to heal wounds including absorptivity, oxygen permeability, and non-adherence to the healing tissue, barrier to bacteria, bioactivity and occlusivity...

The fact that cancer is a leading cause of death all around the world has naturally sparked major efforts in the pursuit of novel and more efficient biomarkers that could better serve as diagnostic tools, prognostic predictors, or therapeutical targets in the battle against this type of disease. Mass spectrometry-based proteomics has proven itself as a robust and logical alternative to the immuno-based methods that once dominated the field. Nevertheless, intrinsic limitations of classic proteomic approaches such as the natural gap between shotgun discovery-based methods and clinically applicable results have called for the implementation of more direct, hypothesis-based studies such as those made available through targeted approaches, that might be able to streamline biomarker discovery and validation as a means to increase survivability of affected patients...

Owing to the widespread application value, monoclonal antibodies (MAbs) have become a tool of increasing importance in modern bioscience research since their emergence. Recently, some researchers have focused on the production of MAbs against medical plant-derived natural products (MPNP), the secondary metabolites of medical plants. At the same time, various immunoassay methods were established on the basis of these MPNP MAbs, and then rapidly developed into a novel technique for medical plant and phytomedicine research in the area of quality control, pharmacological analysis, drug discovery, and so on...

For centuries, physicians have recognized aortic aneurysms as an acute threat to life. Therapeutic approaches to the disease began in the 18th century when leading physicians, such as René Laennec and Antonio Valsalva, applied research on circulation and blood coagulation to devise whole-body fasting and bleeding regimens to prevent rupture. After John Hunter's success in ligating arteries to treat peripheral aneurysms, surgeons attempted analogous operations on the aorta, but even the renowned Sir Astley Cooper and William Halsted met with disastrous results...

REVIEW
Danielle S Bassett, Olaf Sporns
Despite substantial recent progress, our understanding of the principles and mechanisms underlying complex brain function and cognition remains incomplete. Network neuroscience proposes to tackle these enduring challenges. Approaching brain structure and function from an explicitly integrative perspective, network neuroscience pursues new ways to map, record, analyze and model the elements and interactions of neurobiological systems. Two parallel trends drive the approach: the availability of new empirical tools to create comprehensive maps and record dynamic patterns among molecules, neurons, brain areas and social systems; and the theoretical framework and computational tools of modern network science...

Geomorphic systems often experience morphological changes that define a trajectory over decadal time periods. These trends can be halted by natural inhibitors such as vegetation, knickpoints, bed armor, or bank cohesion, or by anthropogenic inhibitors such as revetment, levees, or dams. Details about where and how channels and floodplains are stabilized are often poorly understood, which poses a risk that modern projects could unwittingly remove critical stabilizing elements (inhibitors) and unleash an episode of rapid change...

PURPOSE OF REVIEW: Ureteroscopic treatment of urolithiasis has become safer and more effective in the modern era. With a rise in the incidence of bilateral urolithiasis, management dilemma of staged single-side ureteroscopy versus bilateral simultaneous ureteroscopy (BS-URS) is often debatable. This review evaluates the current evidence base for bilateral simultaneous ureteroscopic approach in the modern era. RECENT FINDINGS: A systematic review was conducted from 1990 to June 2016 including all English language articles reporting on outcomes of BS-URS for urolithiasis...
