Envejecimiento Neuronal - ¿Es reversible?

The main risk factor for neurodegenerative disorders, like Alzheimer disease, is aging. At molecular level, aging correlates, in peripheral tissues and in the central nervous system with epigenetic changes at the chromatin (histones and DNA) of aged cells. These molecular changes can be reverted by the expression of the, so called, Yamanaka factors (YF). YF can reprogram (rejuvenate) old cells to cells with structural and functional characteristics of young cells. In the case of the nervous system, upon YF expression, an increase in cognitive capacity can be found. Our future objective, to extrapolate the results found in mice to the human being, will be to look for simple and small chemical compounds with a similar capacity, to that of YF, to revert the structural and functional changes found during aging development.

Interrelations Between Astrochemistry and Galactic Dynamics

This paper presents a review of ideas that interconnect astrochemistry and galactic dynamics. Since these two areas are vast and not recent, each one has already been covered separately by several reviews. After a general historical introduction, and a needed quick review of processes such as stellar nucleosynthesis that gives the base to understand the interstellar formation of simple chemical compounds (e.g., H2, CO, NH3, and H2O), we focus on a number of topics that are at the crossing of the two big areas, dynamics and astrochemistry. Astrochemistry is a flourishing field that intends to study the presence and formation of molecules as well as the influence of them on the structure, evolution, and dynamics of astronomical objects. The progress in the knowledge on the existence of new complex molecules and of their process of formation originates from the observational, experimental, and theoretical areas that compose the field. The interfacing areas include star formation, protoplanetary disks, the role of the spiral arms, and the chemical abundance gradients in the galactic disk. It often happens that the physical conditions in some regions of the interstellar medium are only revealed by means of molecular observations. To organize a rough classification of chemical evolution processes, we discuss about how astrochemistry can act in three different contexts, namely, the chemistry of the early universe, including external galaxies, star-forming regions, and asymptotic giant branch (AGB) stars and circumstellar envelopes. We mention that our research is stimulated by plans for instruments and projects, such as the ongoing Large Latin American Millimeter Array (LLAMA), which consists in the construction of a 12 m sub-mm radio telescope in the Andes. Thus, modern and new facilities can play a key role in new discoveries not only in astrochemistry but also in radio astronomy and related areas. Furthermore, the research on the origin of life is also a stimulating perspective.

The Analysis of a Prototype Installation for Biogas Production from Chosen Agricultural Substrates

Methane production by fermentation is a complex biochemical process, in which micromolecular organic substances are broken down by anaerobic bacteria into simple stabilized chemicals—mainly methane CH4 and carbon dioxide CO2. The organic matter of the slurry consists mainly of fats, proteins and carbohydrates. As a result of biochemical changes in the process of anaerobic decomposition, some of this matter is mineralized to simple chemical compounds. Cattle and pig husbandry offers enormous potential for useable biogas plant substrates. As a result of the constantly increasing amounts of animal husbandry products, and increasingly stringent environmental protection requirements aimed at reusing natural fertilizers, it is necessary to look for alternative processing methods. The need for efficiency in obtaining biogas from substrates (e.g., manure) was met by the laboratory stand presented in this article, for which the Polish patent No. 232200 was obtained. The new technology also allows leaching of the organic liquid, e.g., from manure, and subjecting it to methane fermentation. The solution allows the individual elements of the technological line that determine the fermentation process to be tested under laboratory conditions. It also allows testing of the substrates in terms of fermentation, to determine their physical and chemical characteristics, and then to characterize the fermentation process in terms of the quality and quantity of the resulting biogas and the quality of post-fermentation residues. Compressing biogas for local distribution was also proposed. As part of the research, using a laboratory stand, the organic matter was leached from manure, for the purpose of biogas production. In addition, the biogas yield from manure at varying degrees of maturity was assessed. The best properties in terms of biogas yield forecasting were demonstrated by manure composted for 4–8 weeks.

Polyenals and Polyenones in Aminocatalysis: A Decade Building Complex Frameworks from Simple Blocks

Polyenals and polyenones are simple chemical compounds which can be constructed into large and complex structures by virtue of aminocatalysis. In the past eight years, new aminocatalytic activation modes based on trienamine, cross‐trienamine, tetraenamine, iminium ion, and vinylogous iminium ion intermediates have attracted great attention in the field of asymmetric synthesis. Key to the increasing focus is their inherent ability to allow functionalization of remote sites with excellent stereoselectivities. Moreover, methodologies involving one‐pot, cascade or multicomponent strategies have been developed through the combination of these new activation modes with classical activation modes. In the course of expanding the applicability of organocatalysis, polyenals and polyenones have been introduced as simple and novel substrates, which have enabled the discovery of new concepts for the synthesis of many diverse and complex privileged structures.

Tailoring Hydrothermal Vent Biodiversity Toward Improved Biodiscovery Using a Novel in situ Enrichment Strategy.

Deep-sea hydrothermal vents are amongst the most extreme environments on Earth and represent interesting targets for marine bioprospecting and biodiscovery. The microbial communities in hydrothermal vents are often dominated by chemolithoautotrophs utilizing simple chemical compounds, though the full extent of their heterotrophic abilities is still being explored. In the bioprocessing industry, where degradation of complex organic materials often is a major challenge, new microbial solutions are heavily needed. To meet these needs, we have developed novel in situ incubators and tested if deployment of recalcitrant materials from fish farming and wood-pulping industries introduced changes in the microbial community structure in hot marine hydrothermal sediments. The incubation chambers were deployed in sediments at the Bruse vent site located within the Jan Mayen vent field for 1 year, after which the microbial populations in the chambers were profiled by 16S rRNA Ion Torrent amplicon sequencing. A total of 921 operational taxonomic units (OTUs) were assigned into 74 different phyla where differences in community structure were observed depending on the incubated material, chamber depth below the sea floor and/or temperature. A high fraction of putative heterotrophic microbial lineages related to cultivated members within the Thermotogales were observed. However, considerable fractions of previously uncultivated and novel Thermotogales and Bacteroidetes were also identified. Moreover, several novel lineages (e.g., members within the DPANN superphylum, unidentified archaeal lineages, unclassified Thermoplasmatales and Candidatus division BRC-1 bacterium) of as-yet uncultivated thermophilic archaea and bacteria were identified. Overall, our data illustrate that amendment of hydrothermal vent communities by in situ incubation of biomass induces shifts in community structure toward increased fractions of heterotrophic microorganisms. The technologies utilized here could aid in subsequent metagenomics-based enzyme discovery for diverse industries.

A quantitative evolved gas analysis for extra-terrestrial samples

Evolved gas analysis (EGA) has been successfully applied to the studies of meteorites and Apollo lunar samples. It consists of linear heating of a material with registration of the released volatile compounds, typically using a spectrometric technique. However, so far no quantitative comparison was possible of the amount of gases released during heating of a sample. To address this limitation, we have developed a Quantitative EGA (QEGA) technique using our custom-built Finesse mass spectrometry system. It is based on calibration of the quadrupole mass spectrometer with reference gases (e.g. CO2, CO, H2, O2, N2 or their mixtures with known relative abundances) with known flow rate. The method was tested using simple chemical compounds such as CaCO3, which give well-known amounts of pure gases during their thermal decomposition. We present initial QEGA data on two reference meteorites, Allende and Murchison. Our QEGA work is also informing the design and operation of ProSPA spaceflight instruments being developed to perform analogous experiments in situ on the lunar surface through the European Space Agency’s PROSPECT payload on Luna 27.

Magnetofluorescent nanohybrid comprising polyglycerol grafted carbon dots and iron oxides: Colloidal synthesis and applications in cellular imaging and magnetically enhanced drug delivery.

Multifunctional nanohybrids are attracting increasing attention for potential biomedical applications such as bioimaging and drug delivery due to their combined advantages of individual components. However, challenges in the improvement of their synthesis and colloidal stability to facilitate practical biomedical applications still remain. In this work, we report an efficient synthetic approach to fabricate magnetofluorescent nanohybrid (IO-PG-CD) comprising fluorescent carbon dots (CDs) and magnetic iron oxide nanoparticles (IOs) through polyglycerol (PG) mediated covalent linkage in aqueous media. CDs and IOs are first grafted with PG layer, and then functionalized with carboxyl and amino groups, respectively. The resulting CD-PG-COOH and IO-PG-NH2 handled as simple chemical compounds are integrated through EDC/NHS crosslinking to obtain the desired IO-PG-CD nanohybrid. The unprecedented hydrophilicity of PG layer endows IO-PG-CD nanohybrid with excellent colloidal stability in various physiological media, facilitating biomedical applications in vitro and in vivo. IO-PG-CD nanohybrid exhibits low cytotoxicity and its uptake by cells can be obviously enhanced by external magnetic attraction. The internalized IO-PG-CD nanohybrid emits multicolor fluorescence as observed by confocal fluorescence microscopy, demonstrating much better photostability than the nanoparticle labeled with organic dye. Taking advantage of enormous chelating carboxyl groups on the surface of IO-PG-CD nanohybrid, platinum-based anticancer drug was loaded on the surface (IO-PG-CD/Pt) through complexation and delivered into cancer cells in a magnetically enhanced manner, killing the cancer cells efficiently in vitro. Moreover, in vivo cancer therapy indicates that the external magnetic attraction also obviously improves the anticancer efficacy of IO-PG-CD/Pt in HeLa subcutaneous xenografts.

Ethical and philosophical problems of society and medicine in the XXI century

For the success of their individual activities, everyone (especially – a doctor) should be able to receive the latest professional information correlate its important elements of their own practical experience, ultimately, at least, to take effective additional training in special circumstances. This requires a rich and modern information field of state. The older generation of doctors is formed in the conditions that existed in the Soviet Union and the Soviet Ukraine. Then there were no unscientific or outright false materials. Unfortunately, in modern Ukraine practically disappeared restrictive barriers anti-sciences to esoteric and the other discipline, which dramatically reduced the quality of our national information field and considerably complicated the activities of all medical areas and relevant sector of higher education. The information revolution has changed everything. IBM has invited 600 scientists to input a large amount of information from hundreds of modern science in an unknown volume database. Complex supercomputer and the database named "Watson". This is the first ever active integrator scientific knowledge. Watson won the race with a medical diagnosis in two groups of experts. We are confident of good prospects for scientific integrators and personalized medicine of the XXIst century. In the article the negative phenomenon widening gap between the practice of medicine and scientific discoveries is considered. It is increased the time interval between the formulation of ideas of new drugs before they spread to the network of pharmacies and hospitals. Once it had been weeks or months, now – 12-17 or more years. Earlier drugs in the form of simple chemical compounds or combination of substances from the environment (most famous source – medicinal plants) were produced and used by the doctor. Nowadays everything is much more complicated that article demonstrated appeal to the information made available on the Internet for several days in mid-May 2016. It is noted that market competition in medicine and morality contradict the culture of the Ukrainian people. Therefore, the national medical education should develop the foundations of the Hippocratic Oath, traditions and use discoveries of modern science

Experimental study of hydrodynamic effects in the inverse water hydrocarbon emulsions flow in microchannels

The paper presents results of hydrodynamic and rheological studies of the inverse water hydrocarbon emulsions. The success of the application of invert emulsions in the petroleum industry due, along with the high viscosity of the emulsion, greatly exceeding the viscosity of the carrier phase, the dynamic blocking effect, which consists in the fact that the rate of flow of emulsions in capillary structures and cracks falls with time to 3-4 orders, despite the permanent pressure drop. The reported study shows an increase in viscosity with increasing concentration or dispersion of emulsion. The increase in dispersion of w/o emulsion leads to an acceleration of the onset of dynamic blocking. The use of microfluidic devices, is made by soft photolithography, along with high-speed photography (10,000 frames/s), allowed us to see in the blocking condition the deformation of the microdroplets of water in inverse emulsion prepared from simple chemical compounds.

Steady flow a highly concentrated emulsion in a cylindrical channel with stepped constriction

In experimental studies it was found that the effect appear during flow not only in technical emulsions, but also emulsions from simple chemical compounds. It was also suggested that in the region of narrowing of the channel, there is accumulation of particles in the dispersed phase, as a result occurs dynamic blocking. A mathematical model of the flow of a highly concentrated emulsion in a channel with a stepped constriction is constructed.

Upgrading oxygenated Fischer-Tropsch derivatives and one-step direct synthesis of ethyl acetate from ethanol - examples of the desirability of research on simple chemical compounds transformations.

Oxygenates formed as by-products of Fischer-Tropsch syntheses can be transformed into other Fischer-Tropsch derived oxygenates instead of treating them as unwanted chemicals. One-step direct synthesis of ethyl acetate from ethanol is feasible with the use of some heterogeneous catalysts. Despite their apparent simplicity, both transformations are discussed as targeted fields of research. Furthermore, the two concepts are justified due to the environmental protection. Arguments regarding the Fischer-Tropsch process are focused on the opportunities of the utilization of undesirable by-products. The effective striving for their utilization can make the oxygenates the targeted products of this process. Arguments regarding the one-step direct synthesis of ethyl acetate underline the environmental protection and sustainability as a less waste-generating method but, above all, highlight the possibility of reducing the glycerol overproduction problem. The production of ethyl acetate from bioethanol and then transesterification of fats and oils with the use of ethyl acetate allows managing all the renewable raw materials. Thus, the process enables the biosynthesis of biodiesel without glycerine by-product and potentially would result in the increase in the demand for ethyl acetate.Graphical .Electronic supplementary materialThe online version of this article (doi:10.1186/s13065-014-0077-9) contains supplementary material, which is available to authorized users.

Development of efficient ion supply of (58)Fe from (58)Fe(C5H5)2, and quick switching between therapy and material science at the Heavy-Ion Medical Accelerator in Chiba realized a new (57)Mn in-beam emission Mössbauer spectroscopy measurement system. Application to simple binary chemical compounds, MgO and NaF, proved the usefulness of the system to probe chemical and physical behaviors of trace impurities in solids. Annealing of lattice defects produced by the implantation and β-decay of (57)Mn and/or γ-ray emission recoil was observed by a local probe.

Enthalpy and temperature of the phase change solid–liquid – An analysis of data of compounds employing entropy

Latent heat storage with materials undergoing a phase change solid–liquid is gaining increasing interest due to its potential for applications in energy systems. The demand for optimized storage materials has led to an intensification of materials research in recent years. The research focuses mainly on developing materials with high storage density, and related to this the question what the theoretical limit is. For both it is necessary to understand what affects the melting enthalpy and melting temperature on the atomic and molecular level. In this paper, 1120 different materials (elements and simple chemical compounds) have been analysed to find out what affects the melting enthalpy, entropy, and temperature on the atomic and molecular level. The analysis has been performed plotting data of hm per atom as a function of sm/R per atom. While loosening the inter-particle bonds is a necessity for the change of phase from solid to liquid, several other effects have been identified. The most important ones are a change of bond type between the solid and the liquid phase, and a change of the particle structure, which is equal to a chemical reaction. The latter shows that latent heat storage employing a phase change solid–liquid can include a chemical reaction.

Decomposition differences of labile carbon from litter to soil in a tropical rain forest and rubber plantation of Xishuangbanna, southwest China

We used solid-state carbon-13 nuclear magnetic resonance (NMR) to compare chemical compositions of carbon in plant litter, forest floor and soil in a native seasonal rain forest (SR) with those in a rubber plantation (RP) in Xishuangbanna, southwest China. We also applied a sequential fumigation–incubation (SFI) procedure to characterize the chemical compositional change of soil organic carbon (SOC) during soil degradation. It was found that RP had 1.5–1.7 times greater in alkyl C0–45ppm proportions and smaller O-alkyls C45−110 fractions in litter and forest floor materials than SR. Degradation of labile organic carbon (LOC) in fresh litter was primarily limited to O-alkyl C and O2-alkyl C in both forests, suggesting litters of RP were less decomposable than that of SR. SOC in RP was 2.3 percent higher in aromatics C110–160ppm proportions and 0.03 percent in aromaticity value than those in SR. With the absence of new C input and fauna, degradation of soil LOC companied with loss of carbonyls C160−220ppm in RP, and alkyl C and aromatics C110–160ppm in SR. Our data indicated that rubber planting induced carbon loss and extensive humification in the soil. Sources of the decomposed soil LOC can compose of both simple and complex chemical compounds.

Protein and Peptide-Based Therapeutics in Periodontal Regeneration

Protein and peptide-based therapeutics provide a unique strategy for controlling highly specific and complex biologic actions that cannot be accomplished by simple devices or chemical compounds. This article reviews some of the key characteristics and summarizes the clinical effectiveness of protein and peptide-based therapeutics targeting periodontal regeneration.Evidence Acquisition: A literature search was conducted of randomized clinical trials and systematic reviews evaluating protein and peptide-based therapeutics for the regeneration of periodontal tissues of at least 6 months duration. Data sources included PubMed and Embase electronic databases, hand-searched journals, and the ClinicalTrials.gov registry.Evidence Synthesis: Commercially marketed protein and peptide-based therapeutics for periodontal regeneration provide gains in clinical attachment level and bone formation that are comparable or superior to other regenerative approaches. Results from several clinical trials indicate that protein and peptide-based therapies can accelerate repair and regeneration when compared with other treatments and that improvements in clinical parameters continue beyond 12 months. Protein and peptide-based therapies also exhibit the capacity to increase the predictability of treatment outcomes.Conclusions: Clinical and histologic studies support the effectiveness of protein- and peptide-based therapeutics for periodontal regeneration. Emerging evidence suggests that the delivery devices/scaffolds play a critical role in determining the effectiveness of this class of therapeutics.

Dynamic blocking and dispersions rheology at phase transition

In the flow in the microchannel of reverse water hydrocarbon emulsions, it is found the dynamic blocking effect. The essence of the effect is that the flow of the emulsion through the section of the microchannel stops with time, despite the permanent pressure drop. The difference of this work from previous ones is that for the experiments was prepared the emulsion of simple chemical compounds. For visualization of the structure formed in the capillary after blocking, the dispersed phase was introduced fluorescing component. It is studied and compared the rheological properties of the emulsion and formed from it in the phase transition suspension.
