Heavy-metal-contaminated soil threatens human health and environmental safety. Complete remediation of contaminated soil is expensive; therefore, phytomanagement has emerged as a cost-effective alternative. The current study investigated mulberry tree (Morus alba) plantation, silkworm cultivation, and silk production as phytomanagement options. Results defined the safety of planting mulberry trees in soils with lead (Pb) and arsenic (As) concentrations lower than 369 and 180mgkg(-1), respectively. Silkworms fed with mulberry leaves collected from slightly contaminated soil exhibited productive growth and normal silk production...

Cloud computing is a recent tendency in IT that moves computing and data away from desktop and hand-held devices into large scale processing hubs and data centers respectively. It has been proposed as an effective solution for data outsourcing and on demand computing to control the rising cost of IT setups and management in enterprises. However, with Cloud platforms user's data is moved into remotely located storages such that users lose control over their data. This unique feature of the Cloud is facing many security and privacy challenges which need to be clearly understood and resolved...

Compensatory growth (CG) is utilised worldwide in beef production systems as a management approach to reduce feed costs. However the underlying biology regulating the expression of CG remains to be fully elucidated. The objective of this study was to examine the effect of dietary restriction and subsequent re-alimentation induced CG on the global gene expression profile of ruminal epithelial papillae. Holstein Friesian bulls (n = 60) were assigned to one of two groups: restricted feed allowance (RES; n = 30) for 125 days (Period 1) followed by ad libitum access to feed for 55 days (Period 2) or (ii) ad libitum access to feed throughout (ADLIB; n = 30)...

The analysis of the network structure of the functional connectivity data constructed from fMRI images provides basic information about functions and features of the brain activity. We focus on the two features which are considered as relevant to the brain activity, the criticality and the constraint regarding energy consumptions. Within a wide variety of complex systems, the critical state occurs associated with a phase transition between distinct phases, random one and order one. Although the hypothesis that human brain activity is also in a state of criticality is supported by some experimental results, it still remains controversial...

BACKGROUND: Various approaches such as antegrade trans-septal, retrograde transfemoral and transapical techniques have been used to close mitral paravalvular leak (PVL) in patients with an aortic prosthesis. During the implementation of these techniques, an arteriovenous guidewire loop is often created for device delivery. However, passing through a mechanical aortic valve may cause hemodynamic compromise and prolong the procedure. To date, no studies have evaluated antegrade mitral PVL closure without the use of an arteriovenous wire loop in patients with a mechanical aortic prosthesis...

In lung inflammation, neutrophils are the first leukocytes migrating to an inflammatory site, eliminating pathogens by multiple mechanisms. The term "migration" describes several stages of neutrophil movement to reach the site of inflammation, of which the passage of the interstitium and basal membrane of the airway are necessary to reach the site of bronchial inflammation. Currently, several methods exist (e.g., Boyden Chamber, under-agarose assay, or microfluidic systems) to assess neutrophil mobility. However, these methods do not allow for parameterization on single cell level, that is, the individual neutrophil pathway analysis is still considered challenging...

BACKGROUND: Streptococcus pneumoniae (SP) pneumonia is often treated empirically as diagnosis is challenging because of the lack of a perfect test. Using BinaxNOW-SP, a urinary antigen test, as an add-on to standard cultures may not only increase diagnostic yield but also increase costs. OBJECTIVE: To estimate the sensitivity and specificity of BinaxNOW-SP and subsequently estimate the cost-effectiveness of adding BinaxNOW-SP to the diagnostic work-up. DESIGN: We fit a Bayesian latent-class meta-analysis model to obtain estimates of BinaxNOW-SP accuracy that adjust for the imperfect accuracy of culture...

Clinical trials of experimental treatments must be designed with primary endpoints that directly measure clinical benefit for patients. In many disease areas, the recognised gold standard primary endpoint can take many years to mature, leading to challenges in the conduct and quality of clinical studies. There is increasing interest in using shorter-term surrogate endpoints as substitutes for costly long-term clinical trial endpoints; such surrogates need to be selected according to biological plausibility, as well as the ability to reliably predict the unobserved treatment effect on the long-term endpoint...

Antibodies that antagonize cell signaling pathways specific to their targeted receptor are invaluable tools to study and treat malignancies, but their utility is limited by high production costs and treatment dosages. Researchers have shown that antibodies conjugated to nanoparticles display increased affinity for their target relative to freely delivered antibodies due to multivalency, and this study investigates how this multivalency can enable antibody-nanoparticle conjugates to inhibit oncogenic cell signaling more effectively than freely delivered antibodies...

Food trade globalization and the growing demand for selected food varieties have led to the intensification of adulteration cases, especially in the form of species substitution/mixing with cheaper taxa. This phenomenon acquired huge economic impact and sometimes even public health implications. DNA barcoding represents a well-proven molecular tool to assess the authenticity of food items, although its diffusion is hampered by analytical constraints and timeframes that are often prohibitive for food market...

Cell-based therapies utilize transplantation of living cells with therapeutic traits to alleviate numerous diseases and disorders. The use of such biological agents is an attractive alternative for diseases that existing medicine cannot effectively treat. Although very promising, translating cell therapy to the clinic has proven to be challenging, due to inconsistent results in preclinical and clinical studies. To examine the underlying cause for these inconsistencies, it is crucial to noninvasively monitor the accuracy of cell injection, and cell survival and migration patterns...
