REVIEW
Gregory I Giles, Muhammad Jawad Nasim, Wesam Ali, Claus Jacob
Fifteen years ago, in 2001, the concept of "Reactive Sulfur Species" or RSS was advocated as a working hypothesis. Since then various organic as well as inorganic RSS have attracted considerable interest and stimulated many new and often unexpected avenues in research and product development. During this time, it has become apparent that molecules with sulfur-containing functional groups are not just the passive "victims" of oxidative stress or simple conveyors of signals in cells, but can also be stressors in their own right, with pivotal roles in cellular function and homeostasis...

Plant architecture is an important agronomic trait, and improving plant architecture has attracted the attention of scientists for decades, particularly studies to create desirable plant architecture for high grain yields through breeding and culture practices. However, many important structural phenotypic traits still lack quantitative description and modeling on structural-functional relativity. This study defined new architecture indices (AIs) derived from the digitalized plant architecture using the virtual blade method...

Oral squamous cell carcinoma (OSCC) accounting for about 90% of malignant oral lesions is the 6th most common malignancy worldwide. Diagnostic delay may contribute to dismal survival rate therefore, there is a need for developing specific and sensitive biomarkers to improve early detection. Hungarian population occupies the top places of statistics regarding OSCC incidence and mortality figures therefore, we aimed at finding potential salivary protein biomarkers suitable for the Hungarian population. In this study we investigated 14 proteins which were previously reported as significantly elevated in saliva of patients with OSCC...

Thin films mimicking the structure and composition of the extra-cellular matrix (ECM) are potentially attractive as biomaterials for cell contacting applications. Layer-by-layer (LbL) assembly of a biological polycation, poly(l-lysine) (PLL), and a common ECM protein, fibronectin (Fn), was employed here to construct nanoscale, ECM mimicking films. Incremental film thickness and interfacial charge magnitude are observed to diminish with layer number, resulting in sub-linear film growth scaling and saturation after about 10 layers...

PCPP, a well-defined polyphosphazene macromolecule, has been studied as an immunoadjuvant for a soluble form of the post-fusion glycoprotein (RSV sF) of RSV, which is an attractive vaccine candidate for inducing RSV-specific immunity in mice and humans. We demonstrate that RSV sF-PCPP formulations induce high neutralization titers to RSV comparable to Alum formulations even at a low PCPP dose and protect animals against viral challenge both in the lung and upper respiratory tract. PCPP formulations were also characterized by Th1-biased responses, compared to Th2-biased responses that are more typical for RSV sF alone or RSV sF-Alum formulations, suggesting an inherent immunostimulating activity of the polyphosphazene adjuvant...

A new and efficient method for the synthesis of unsymmetrical 1,3-butadiynes by gold-catalyzed C(sp)-C(sp) cross-coupling of terminal alkynes with alkynyl hypervalent iodine(III) reagents has been developed. The reaction features high selectivity and efficiency, mild reaction conditions, wide substrate scope, and functional-group compatibility, and is a highly attractive complement to existing methods. Mechanistic studies reveal that formation of a phenanthrolinyl-ligated gold(I) complex is crucial for the efficiency and selectivity of the target transformation...

Phenotypic plasticity of microbial cells has attracted much attention and several research efforts have been dedicated to the description of methods aiming at characterizing phenotypic heterogeneity and its impact on microbial populations. However, different approaches have also been suggested in order to take benefit from noise in a bioprocess perspective, e.g. by increasing the robustness or productivity of a microbial population. This review is dedicated to outline these controlling methods. A common issue, that has still to be addressed, is the experimental identification and the mathematical expression of noise...

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...

All-vanadium redox flow batteries (VRBs) have attracted considerable interest as promising energy storage devices which can allow the efficient utilization of renewable energy sources. The membrane, which separates the porous electrodes in a redox flow cell, is one of the key components in VRBs. High rates of cross-over of vanadium ions and water through the membrane impair the efficiency and capacity of a VRB. Thus, membranes with low permeation rate of vanadium species and water are required, also characterized by low resistance and stability in the VRB environment...

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...

Electrochemical water oxidation is the key technology in water-splitting reactions and rechargeable metal-air batteries, which is very attractive for renewable energy conversion and storage. Replacement of precious catalysts with cost-effective and highly active alternatives is still a great challenge. Herein, based on theoretical predictions, holey structures are designed and fabricated on the free-standing conventional 2D OER catalyst. By well-controlled defects engineering, uniform tiny holes are created on the free-standing Ni(OH)2 nanosheets via a sol-gel method, with the embedded Zn components as the template for holes production...

The metal catalyzed cross-coupling reactions are one of the most important transformations in organic synthesis. Copper catalysis has received great attention due to its low toxicity and inexpensive nature. However, traditional Ullmann-type coupling reactions suffered from limited substrate scope and harsh reaction conditions. The introduction of some bidentate ligands such as amino acids, diamines, 1,3-diketones and oxalic diamides during the past two decades has totally changed its scenario, allowing the coupling reactions of aryl halides and nucleophiles to take place at both low reaction temperatures and catalytic loadings...

Core-shell architectures offer an effective way to tune and enhance the properties of noble metal catalysts. Here, we demonstrate the synthesis of Pt shell on titanium tungsten nitride core nanoparticles (Pt/TiWN) by high temperature ammonia nitridation of a parent core-shell carbide material (Pt/TiWC). X-ray photoelectron spectroscopy revealed significant core-level shifts for Pt shells supported on TiWN cores, corresponding to increased stabilization of the Pt valence d-states. The modulation of the electronic structure of the Pt shell by the nitride core translated into enhanced CO tolerance during hydrogen electrooxidation in the presence of CO...

Hybrid halide perovskite solar cells (PSCs) exceeding 22% power conversion efficiencies (PCEs) have attracted considerable global attention due to the intrinsic nature of perovskite. Although we all know about that perovskite plays a significant role in the operation of PSCs, the fundamental theories associated with perovskite have not been resolved by the exponential increase in research effort. This raises questions about whether the first-principles calculations are sufficiently addressing the underlying issues in perovskite...

Floral nectar can affect the fitness of insect-pollinated plants, through both attraction and manipulation of pollinators. Self-incompatible insect-pollinated plants receive more insect visits than their self-compatible relatives, and the nectar of such species might face more risk to be infested by the pathogens carried by pollinators than self-compatible plants. Proteins in nectar (nectarins) play an important role in the protection of nectar, but little is known regarding nectarins in self-incompatible species...

Curing 'homosexuality' or same-sex attraction has been a recurrent trope in Western psychiatry and mental health services for over a century. Despite the progress made in the UK with equality legislation, improvements in general social attitudes and the slowly increasing confidence of lesbian, gay and bisexual (LGB) individuals and communities (Carr, 2005), it appears to pose challenges for practice in the UK even today. This was recently highlighted in 2014 when the Department of Health requested the publication of a consensus statement from major UK mental health professional bodies outlining concern about and opposition to 'conversion' or 'reparative' therapy being offered to LGB people by practitioners (often working within a religious frame of reference) claiming to be able to 'cure' same-sex attraction (UK Council for Psychotherapy, 2014)...

There is an expectation that to meet regulatory requirements, and avoid or minimize animal testing, integrated approaches to testing and assessment will be needed that rely on assays representing key events (KEs) in the skin sensitization adverse outcome pathway. Three non-animal assays have been formally validated and regulatory adopted: the direct peptide reactivity assay (DPRA), the KeratinoSens™ assay and the human cell line activation test (h-CLAT). There have been many efforts to develop integrated approaches to testing and assessment with the "two out of three" approach attracting much attention...

Halogenated graphenes have been attracting great attention in the recent years. The currently used methods are usually non-specific and halogen groups are randomly distributed over the graphene surface. The selective functionalization based on well known reaction mechanism allowed selective functionalization of graphene sheets. We show the application of Hunsdicker based reaction on the graphene oxide for selective bromination of graphene oxide. The chemical analysis using various spectroscopic methods proved a highly effective functionalization...
