Published: November 2019

Origins of life chemistry has progressed from seeking out the production of specific molecules to seeking out conditions in which macromolecular precursors may interact with one another in ways that lead to biological organization. Reported precursor synthesis networks generally lack biological organizational attributes. Radical species are highly reactive, but do their chemical reaction networks resemble living systems? Here we report the results of radiolysis reaction experiments that connect abundant geochemical reservoirs to the production of carboxylic acids, amino acids, and ribonucleotide precursors and study the topological properties of the resulting network. The network exhibits attributes associated with biological systems: it is hierarchically organized, there are families of closed loop cycles, and the species and cycle histograms exhibit heterogeneous (heavy-tailed) distributions. The core cycles of the network are made possible by the high reactivity of radical species such as H and OH. Radiolysis is implicated as a unique prerequisite for driving abiotic organosynthetic self-organization.

Authors: Naruse Yuji , Takamori Atsushi
Published: November 2019

Goodenough-Kanamori-Anderson rules (GKA rules) in superexchange interaction discriminate the magnetic properties of two magnetic metal ions bridged with an anion. We propose here that the GKA rules can be explained in terms of the orbital phase continuity-discontinuity property of cyclic orbital interaction including direct metal-metal orbital interaction.
Magnesium-Accelerated Maillard Reactions Drive Differences in Adjunct and All-Malt Brewing
Authors: Omari Isaac , Charnock Hannah , Fugina Alexa , Thomson Euan , McIndoe J Scott
Published: November 2019

Magnesium impacts key processes in brewing including yeast metabolism and mash pH but is typically overshadowed in brewing studies, owing to the established centrality of calcium. Using flame atomic absorption spectroscopy (FAAS), we have identified a 33.7% average increase in magnesium concentration in commercially available beers brewed with 100% barley malt versus those brewed with adjunct grains. Parallel analysis of brewing grains implicates rice in driving this discrepancy. Given the known catalytic properties of magnesium, we investigated its role in beer color development via Maillard chemistry using model systems and wort (unfermented beer). Kinetic data were obtained by ultraviolet-visible spectrometry and reaction species were identified by electrospray ionization mass spectrometry. Magnesium accelerated Maillard chemistry in all systems in a dose-dependent manner. It is proposed that magnesium inhibits water mobility and serves as a Lewis acid catalyst to facilitate Maillard reactions.
Probing the Complex Loading Dependent Structural Changes in Ultra-High Drug Loaded Polymer Micelles by Small-Angle Neutron Scattering

Published: November 2019

Drug loaded polymer micelles or nanoparticles are being continuously explored in the fields of drug delivery and nanomedicine. Commonly, a simple core-shell structure is assumed, in which the core incorporates the drug and the corona provides steric shielding, colloidal stability, and prevents protein adsorption. Recently, the interactions of the dissolved drug with the micellar corona have received increasing attention. Here, using small-angle neutron scattering, we provide an in-depth study of the differences in polymer micelle morphology of a small selection of structurally closely related polymer micelles at different loadings with the model compound curcumin. This work supports a previous study using solid state nuclear magnetic resonance spectroscopy and we confirm that the drug resides predominantly in the core of the micelle at low drug loading. As the drug loading increases, neutron scattering data suggests that an inner shell is formed, which we interpret as the corona also starting to incorporate the drug, whereas the outer shell mainly contains water and the polymer. The presented data clearly shows that a better understanding of the inner morphology and the impact of the hydrophilic block can be important parameters for improved drug loading in polymer micelles as well as provide insights into structure-property relationships.

Published: November 2019

Many cellular protein-protein interactions (PPIs) are mediated by phosphoserine. The specific targeting of these PPIs by phosphoserine-containing small molecules has been scarce due to the dephosphorylation of phosphoserine and its charged nature at physiological pH, which hinders its uptake into cells. To address these issues, we herein report the masking of the phosphate group of phosphoserine with biocleavable aryloxy triester phosphoramidate groups. A combination of in vitro enzymatic assays and in silico studies, using carboxypeptidase Y and Hint-1 respectively, showed that the phosphate masking groups are metabolized to release phosphoserine. To probe the applicability of this phosphoserine masking approach, it was applied to a phosphoserine-containing inhibitor of 14-3-3 dimerization, and this generated molecules with improved pharmacological activity in cells compared to their unmasked phosphoserine-containing parent compound. Collectively, the data showcases the masking of phosphoserine with biocleavable aryloxy triester phosphoramidate masking groups as an efficient intracellular delivery system for phosphoserine-containing molecules.
Efficacy of Garlic and Onion against virus
Authors: Neha Sharma
Published: November 2019

In the current scenario, pharmaceutical industry is dependent on chemical based drugs to treat viral infection. However, these drugs are known to induce many side effects in human body. There is pressing need to promote safe alternative to chemical based antiviral drugs. Onion and garlic are natural sources which are known to possess antiviral properties. It is well known that onion and garlic are rich source of organosulfur compounds. Organosulfur compounds like quercetin and allicin are associated with inhibition of viral infection. These chemicals can hinder virus attachment to host cell, alter transcription and translation of viral genome in host cell and also affect viral assembly. Quercetin can affect entry and attachment of Enterovirus and Influenza virus on host cell. This compound also has ability to inhibit RNA polymerase which is necessary for viral replication. Quercetin also inhibit process by which virus alter signalling pathway in host cell. Organosulfur compounds like allicin, diallyl trisulfide and ajoene are main chemicals which impart antiviral property to garlic. It is known that allicin can pass through phospholipid membrane of cell and can further contribute in inhibiting viral multiplication. Considering numerous studies which corroborate antiviral effect of onion and garlic, this paper recommends consumption of these plants as a safe alternative to prevent virus infection.

Validity and reliability of a handheld blood glucose monitor during exercise and an oral glucose tolerance test
Authors: Granderson Davoncie M. , Camic Clayton L. , Chomentowski Peter J. , Howell Steven M. , Sebastião Emerson
Published: November 2019

The purpose of the present study was
to examine the validity and reliability of the handheld Nova Max Plus blood
glucose monitor during an oral glucose tolerance test and 60-minute bout of
exercise. Thirty subjects (mean age±SD=22.3±1.9 years; body mass=77.6±14.2 kg)
volunteered for an oral glucose tolerance test or 60-minute treadmill test. Blood
glucose concentrations were measured from the fingertip at six time points
during both tests. The reference method of blood glucose analysis was the
Yellow Springs Instruments (YSI) 2300. Our results indicated that the blood
glucose values provided by the Nova Max Plus were significantly (p<.05) greater
than the YSI 2300 at all-time points of the oral glucose tolerance test and
treadmill test. In addition, the Nova Max Plus exhibited an overall mean
absolute relative deviation (±SD) of 9.0 (±7.0) and did not meet the 95% accuracy
requirements of ISO 15197:2013. The Bland-Altman plot for constant error (YSI
2300 – Nova Max Plus) versus the reference method (YSI 2300) indicated an
average negative bias (-8.2 mg·dL-1) that increased (r=-0.23)
at higher blood glucose values. Intra-device reliability analyses for the Nova
Max Plus demonstrated the ICC was R=0.99
and CV=3.0%, with no mean differences between the test and retest values. These
findings suggested that the Nova Max Plus provided highly reliable, yet
inaccurate blood glucose values compared to the YSI 2300 during the dynamic
conditions associated with an oral glucose tolerance test and exercise.

Este trabajo analiza la entomología Forense. Tal abordaje se justifica en consideración a que la entomología sirve para determinar el intervalo pos mortem, I.P.M, esclarecer hechos de muerte, traumas o mutilaciones antes de la muerte, asimismo lugar donde ocurrió la muerte, esclarecer circunstancias de abuso, abandono, como la identificación del ADN humano a partir de insectos, recuperación de sustancias tóxicas en larvas para determinar alcoholemia, medicamento y droga de abuso. Este propósito fue conseguido a través de la revisión bibliográfica, experimento en campo, se sigue el protocolo sugerido por Goff, García, Arnandos, Romera y Luna (2004) con algunas modificaciones. El estudio evidenció que los insectos son los primeros en llegar a un cuerpo en descomposición, esto ocurre en determinada secuencia de manera natural, produciéndose una sucesión de especies, siguiendo ese patrón que es, al mismo tiempo, irrepetible, ya que varía en función al lugar, la época del año. Según el tiempo de desarrollo, los estadios larvales de los insectos se puede determinar con bastante precisión las posibles causas de muerte o el intervalo post mortem (IPM) (Flores & Leonardo, 2012). Como conclusión, el entomólogo que entienda estos patrones puede proveer tanto al médico forense, como a las entidades competentes, información sumamente útil para casos criminales.

Published: November 2019

El conocimiento que nos proporciona actualmente la neurociencia sobre el modo en que el cerebro registra y almacena la información nos permite identificar los procedimientos más eficaces para conseguir una enseñanza de calidad. Cuando aprendemos se forman nuevas conexiones (sinapsis) entre las neuronas que albergan el conocimiento. Si la práctica repetida es esencial para establecer hábitos motores y mentales, el conocimiento semántico requiere comparación y contraste entre informaciones diferentes. Ello pone en juego estructuras cerebrales como el hipocampo, necesario para establecer memorias flexibles y relacionales. Evocar explícitamente, es decir, verbalmente o por escrito, los recuerdos es el mejor modo de reforzar y garantizar el aprendizaje.

Authors: AKDENİZ Galma
Published: November 2019

Aim of this

study was to generate a database of homicide incidents in Turkey in 2017 from

Police Bulletins, to study the characteristics of homicide on a national level,

including temporal homicide patterns. A database of 782 homicide incidents that

took place in 2017 was generated from Police Bulletins. Data on the number of

victims, number of offenders, time and place of homicide, weapon used, and

apprehension of the offender were extracted from the Police Bulletins and used

in SPSS analysis of the data. Incidents identified involved 863 victims of

homicide, including 16 homicide-suicide incidents. Most homicides identified

were one-on-one events. 68,3% of homicides had taken place on the outside. No

statistically significant seasonal effect was found, but December had the

highest frequency of homicide. Religious holidays were not associated with

spike or drops in homicide frequency. It was found that frequency of homicides

drops towards the middle of the week, and increase over the weekend. Over the

course of the day, homicides increased in the afternoons and evening, peaking

at 9pm. Most homicides were committed using a weapon, with firearms used in

61,7% of all homicides. Homicide-suicides were more likely to happen during

winter months, and commonly involved a firearm. While the data is incomplete,

this study confirms on a national level many findings of smaller studies that

have been conducted in Turkey on a local level. Expansion of the database is

needed to improve the understanding of temporal patterns of homicide.

Introduction. In recent years, in occupational pathology, much attention is paid to professionally caused diseases, a special place among which is occupied by cardiovascular pathology. Vascular wall stiff ness is considered as an independent cardiovascular risk factor. This makes it important to study the mechanism of development of arterial stiffness, a key component of which is inflammation.

The aim of the study was to identify the relationship between immune parameters and vascular wall stiff ness according to volumetric sphygmography in workers exposed to industrial aerosols.

Materials and methods. A survey was conducted of 55 men working in conditions of exposure to industrial aerosols, and 32 men who do not have professional contact with industrial pollutants. Serum concentrations of class A and G immunoglobulins, cytokines, tumor necrosis factor α, and C-reactive protein were determined by solid-phase enzyme immunoassay. Assessment of elastic properties of the vascular wall was carried out by volumetric sphygmography.

Results. Increased production of anti-inflammatory interleukin–8, immunoglobulin G and C-reactive protein, as well as increased cardiovascular and ankle vascular index on the right and left in the group working under the influence of industrial aerosols was found. Median concentrations of immunoglobulins, interleukins and C-reactive protein were independent of changes in the value of the cardiovascular ankle vascular index. Increased rigidity of the vascular wall was accompanied by an increase in the production of tumor necrosis factor α. Thus, in the group of persons with increased stiff ness, the level of this cytokine was 3 times higher than in the group of persons with normal values of the cardiovascular-ankle vascular index. The relationship between the cardiovascular ankle vascular index and the concentration of tumor necrosis factor α (r=0.61; p=0.009), C-reactive protein (r=0.54; p=0.02) and feedback with the level of anti-infl ammatory interleukin–10 (r=0.36; p=0.04) was revealed.

Conclusions. The established significant correlations between cytokines (tumor necrosis factor α, interleukin–10), C-reactive protein and individual indicators of volumetric sphygmography (cardio-ankle vascular index) indicate the pathogenetic role of cytokines and acute phase proteins in the violation of elastic properties of the vascular bed in workers under the influence of industrial aerosols.

Introduction. To assess occupational stress, it is important to create an effective system of personalized monitoring of the functional state of workers based on information computer technologies.

The aim of the study was to carry out personalized physiological and hygienic monitoring using a complex of mobile telemetry systems and computer technologies of laterometry and campimetry in real conditions of professional activity.

Materials and methods. 37 athlete rowers aged 15–20 years took part in the research on the basis of voluntary informed consent. In the course of the training, stress responses were recorded according to the results of heart rate telemetry and the stress load index (SLI) was calculated. The blood levels of biochemical markers were detected (creatine kinase — CK-MB, alanine aminotransferase — ALT). Using computer laterometry and campimetry.

Results. In persons with identifi ed signs of stress in terms of laterometry and campimetry in the blood recorded increased ALT (18.9±6.9 IU / l against the group “norm” 14.3±3.4 IU/ l, p=0.01), CC-MV (42±17.5 IU / l against 16±3.5 IU/ l, p=0.02). In the course of training, 60% of athletes had increased values of isn (0.30±0.04).

Conclusions. The introduction of information technologies for personalized monitoring makes it possible to manage the risk of health disorders of workers with high nervous, emotional and physical stress.

The generalized large-scale maps as well as characteristic of the vegetation of three cluster sites of the new nature reserve “Altyn-Dala” (Kazakhstan) were compiled. The studied territory is located in two natural zones – steppe (sub-zone of desert steppes on light chestnut soils) and desert (subzone of northern deserts on brown soils). 7 types of vegetation – steppe, desert, forest, shrub, meadow, paludal and aquatic (aquatic macrophytes) occur on the territory of the nature reserve. Interesting and rare plant communities were recorded.
Halophyte coastal vegetation of the White Sea western part
Authors: Babina N. V.
Published: November 2019

The diversity of coastal vegetation (salt marsh) that includes halophytic herb communities on marine deposits forming under active seawater influence on the White Sea western coast is discussed. The great diversity of coast habitats is responsible for the great variety of vegetation. The vegetation prodromus contains 18 associations (with 3 variants) and 1 community type, belonging to 7 alliances, 5 orders and 5 classes. Classes Zosteretea marinae (sublitoral sea grass vegetation), Potametea pectinati (aquatic meso- and olygotrophic vegetation), Thero-Salicornietea (pioneer annual succulents littoral com­munities) and Honckenyo-Elymetea arenariae (vegeta­tion of sandy, pebbly or gravely beaches, coastal banks and dunes) are represented by in one association for each. Juncetea maritimi (sea shore meadows on weakly and moderate saline substrates), the largest class, provides the main vegetation variety. The characteristics of syntaxa ecology, and global and regional distributions are made. The widespread and rare associations that need an addi­tional study of composition, distribution and synecology are defined. The area of syntaxa distribution are widened to the east. New variant (ass. Festucetum rubrae var. Alopecurus arundinaceus var. nov.) is suggested.
Associations of Sphagnum rubellum Wils. on the bogs of the south-east part of Baltic region
Authors: Smagin V. A. , Napreenko M. G.
Published: November 2019

The paper characterizes the 3 associations comprising plant communities with Sphagnum rubellum in the south-eastern part of the Baltic region. The new syntaxa differ from each other both in their floristic characters and the pronounced affinity to definite regional mire types and particular habitats.

The ass. Drosero-Sphagnetum rubelli is typical of the relatively most thorough ranges. It is observed from the Kaliningrad region to the Karelian Isthmus and, according to the published reference, occurs even throughout the whole area around the Baltic Sea. Its most typical habitat is that of margins of mire lakes and pools.

The ass. Eriophoro-Sphagnetum rubelli occurs in central plateaus of convex plateau-like bogs, typical of the areas adjacent to the Baltic Sea coast. It occupies extended flat mire ecotopes with the water level 0.2–0.25 m deep.

The ass. Empetro-Sphagnetum rubelli is characteristic of the retrogressive complex in the convex bogs of the East-Baltic Province. It is mostly observed along the coast of the Gulf of Finland. Its stands are rather dynamic and unstable in both space and time.

The presence of communities comprised by these 3 associations is an important vegetation character of the series of regional mire types. Assuming an association level of the respective syntaxa seems rational for the purposes of adequate reflection of plant cover diversity.

Published: November 2019

Geodina salmonicolor is shown to be a synonym of G. guanacastensis, the type and only species of the genus. Comparisons of ITS rDNA sequences of a paratype and two recent collections of G. guanacastensis with published ITS sequences of G. salmonicolor,
from the Dominican Republic, show that these are nearly identical. When G. salmonicolor was erected no sequences of the type species were available. Morphological comparisons supports the conspecificity. Details regarding the description of G. salmonicolor are pointed out. A
four-gene phylogeny places Geodina and Wynnea as a supported sister group to the rest of the Sarcoscyphaceae. Species in these genera share morphological traits of cyanophobic spore markings, dark angular outer excipular cells that give rise to hairs and the origin of
several apothecia from a common basal stalk. Their occurrence on soil rather than on wood or plant material distinguish them from other Sarcoscyphaceae. Based on morphology, phylogenic relationships and trophic interactions we erect a new family, Wynneaceae, for Geodina
and Wynnea.
