Lignocellulose represents a potential supply of sustainable feedstock for the production of biofuels and chemicals. There is, however, an important cost and efficiency challenge associated with the conversion of such lignocellulosics. Since its structure is complex and not prone to undergo chemical reactions very easily, chemical and mechanical pretreatments are usually necessary in order to be able to refine them into the compositional building blocks (carbohydrates and lignin), from which value-added platform molecules such as glucose, ethylene glycol, 5-hydroxymethylfurfural, levulinic acid, etc...

Martin Haluzík
A worldwide increase in the prevalence of obesity and type 2 diabetes mellitus along with accompanying chronic, in particular cardiovascular, complications represents one of the leading challenges of current medicine. Despite major advances in diabetes pharmacotherapy, bariatric surgery remains the most effective treatment of diabetes. It not only markedly decreases body weight and improves glucose control but also induces diabetes remission in a significant percentage of patients. According to current recommendations, bariatric surgery is indicated in patients with 3rd degree obesity (even without any complications) or with 2nd degree obesity with complications (e...

Edward McAssey
The relative importance of interactions between mitochondrial and nuclear genes on adaptation has gained increased attention (see Wolff et al., 2014), although experimental systems to make direct tests of its importance are scarce. Mitonuclear epistasis is when nuclear and mitochondrial genes interact, often at the protein level, and variation in these interactions may result in phenotypic differences (Paliwal et al., 2014). These interactions are often found in the mitochondria where the energy-generating electron transport chain (ETC) is located, and consists of both nuclear and mitochondrial proteins...

REVIEW
Radhe Mohan, David Grosshans
In principle, proton therapy offers a substantial clinical advantage over the conventional photon therapy. This is because of the unique depth-dose characteristics of protons, which can be exploited to achieve significant reductions in normal tissue doses proximal and distal to the target volume. These may, in turn, allow escalation of tumor doses, greater sparing of normal tissues, thus potentially improving local control and survival while at the same time reducing toxicity and improving quality of life. Protons, accelerated to therapeutic energies ranging from 70 to 250MeV, typically with a cyclotron or a synchrotron, are transported to the treatment room where they enter the treatment head mounted on a rotating gantry...

This article reviews current knowledge about leishmaniases in Ecuador, proceeding from 1920, when the first human case was described, to the present, mainly focusing on the recent research events published. Regarding basic situations, it appears that 23 of Ecuador's 24 provinces have leishmaniasis-case reports. The disease is one of the mandatory notification infectious diseases in the country since 2005. All the 21,305 cases notified to the Ministry of Public Health, during the period from 2001 through 2014, were said to involve different clinical features of cutaneous leishmaniasis (CL) but not visceral (VL)...

Nowadays, rattle-like or so-called yolk-shell nanostructures have set off a new wave of research in view of their prominent features including large surface area, tunable void and flexible functional core, etc. Herein, rattle-like mesoporous silica nanoparticles (RMSNs) with a pure silica core, a hollow cavity and a mesoporous shell have been successfully fabricated via a surfactant-assisted selective etching strategy. The synthetic approach involves the preparation of solid silica spheres with three-layer different structural silica containing the inner core of pure silica, middle layer of hybrid silica and outer shell of surfactant/SiO2 composite, followed by a hydrothermal treatment in hot water...

In this paper we showed how the notion of heteronormative citizenship embedded in the Polish Constitution was (re)produced in the public sphere, and how heteronormativity as an ideal was slowly undermined by the emergence of new narratives on LGBT families. We did so by first conducting a critical reading of the Polish Constitution, public opinion polls, national censuses, etc. Then, we presented the results of a discourse analysis on families of choice in Poland from crucial public debates of the last decade...

Isometric tasks have been a standard for electromyography (EMG) normalization stemming from anatomic and physiologic stability observed during contraction. Ballistic dynamic tasks have the benefit of eliciting maximum EMG signals for normalization, despite having the potential for greater signal variability. It is the purpose of this study to compare maximum voluntary isometric contraction (MVIC) to non-isometric tasks with increasing degrees of extrinsic variability, i.e., joint range of motion, velocity, rate of contraction, etc...

Health claims and front-of-pack labels (FoPLs) may lead consumers to hold more positive attitudes and show a greater willingness to buy food products, regardless of their actual healthiness. A potential negative consequence of this positivity bias is the increased consumption of unhealthy foods. This study investigated whether a positivity bias would occur in unhealthy variations of four products (cookies, corn flakes, pizzas and yoghurts) that featured different health claim conditions (no claim, nutrient claim, general level health claim, and higher level health claim) and FoPL conditions (no FoPL, the Daily Intake Guide (DIG), Multiple Traffic Lights (MTL), and the Health Star Rating (HSR))...

F Belal, F Ibrahim, Z A Sheribah, H Alaa
In this paper, a simple and highly sensitive spectrofluorimetric method was developed and validated for the determination of entacapone (ETC). The proposed method is based on forming a highly fluorescent product through the reduction of ETC with Zn/HCl. The produced fluorophore exhibits strong fluorescence at λem 345 nm after excitation at λex 240 nm. The use of fluorescence enhancers such as Tween-80 and carboxy methyl cellulose (CMC) greatly enhanced the fluorescence of the produced fluorophore by 150% and 200%, respectively...

Fuzzy graphs are the backbone of many real systems like networks, image, scheduling, etc. But, due to some restriction on edges, fuzzy graphs are limited to represent for some systems. Generalized fuzzy graphs are appropriate to avoid such restrictions. In this study generalized fuzzy graphs are introduced. In this study, matrix representation of generalized fuzzy graphs is described. Completeness and regularity are two important parameters of graph theory. Here, regular and complete generalized fuzzy graphs are introduced...
