Dialogism of Turkic ethnic cultures of the Lower Volga Region in the aspect of semiotic philosophical concepts of the XX century
Authors: Usmanova Adeliya Rustyamovna 
Published: May 2024

The object of the article is the Turkic ethnic groups of the Lower Volga region, which carry their own long-established ethnomusicological traditions, at the same time interacting with each other, related by language group, religion. The subject of the article is the phenomenon of dialogic and polyphonic cultures of the Turkic ethnic groups of the Lower Volga region. The author examines in detail such aspects as dialogism, polyphonism of cultures, which give answers in understanding the centuries-old ethno-cultural processes of interaction and mutual influence. Special attention is paid to the genre and stylistic community of samples of epic khushavaz, the genre of "conversation in saza", instrumental plays of the wedding folklore of the Yurt Tatars and Nogai Karagashes. Typological phenomena include the peculiarities of the ladointonal organization of melodies and plays, groups of intonations with typical properties and acting as stable components are identified in intonation dictionaries. Also, the rhythmic organization that unites multi-genre melodies acts as stable elements. Considering that this problem is interdisciplinary in nature, the methodological foundations were the concepts of Russian philosophers: M.M. Bakhtin, Y.M. Lotman, D.D. Likhachev, as well as the concepts of leading Russian ethnomusicologists: V.A. Lapin, N.I. Zhulanova, etc. Consideration of the principles of the mechanism of dialogue and polyphonism of some Turkic cultures with others united by one region, related by language group, religion, but still bearing their own long-established ethnomusicological traditions, is poorly studied both for the region of the polyethnic Lower Volga region, and in particular, the Astrakhan Region, and in general, in ethnomusicology. This confirms the relevance of this study. but still carrying their own long-established ethnomusicological traditions, it is poorly studied both for the region of the polyethnic Lower Volga region, in particular in the Astrakhan Region, and in general, in ethnomusicology. This confirms the relevance of this study. The main conclusions of the conducted research are the expansion of their own musical genre system in the context of dialogism of cultures.
Effects of high-intensity sprint exercise on neuromuscular function in sprinters: the countermovement jump as a fatigue assessment tool

Published: May 2024

Background
High-intensity sprint exercises (HIS) are central to sprinter training and require careful monitoring of athlete muscle fatigue to improve performance and prevent injury. While the countermovement jump (CMJ) may be used to monitor neuromuscular fatigue (NMF), little is known about the specific effects from HIS. The purpose of this study is to investigate the effects of HIS on the CMJ to assess its utility for assessing NMF following HIS.

Methods
Ten male collegiate 400 m sprinters completed a 400 m sprint fatigue protocol and underwent five CMJ-testing sessions (baseline, 3 minutes, 10 minutes, 1 hour and 24 hours) over two days. Three CMJ trials, performed on a force plate, were completed each trial, with rating of perceived exertion (RPE) recorded as a subjective fatigue measure. Changes in RPE, CMJ variables, force-time and power-time curves at baseline and post fatigue were assessed.

Results
Significant changes were observed in most variables following the fatigue protocol. In particular, concentric mean power remained significantly lower after 24 hours compared to baseline. In addition, the force-time curves exhibited a significant reduction in all conditions following the fatigue protocol. This decline was most pronounced within 50–75%of the concentric phase relative to baseline measurements. Conclusion. Results indicate that the CMJ may be a useful tool for monitoring fatigue in at least 400 m sprinters. These data also indicate that HIS may disproportionately reduce force output in during concentric movement. These insights may improve training prescriptions and injury prevention strategies for sprint athletes.

Background
Engaging in appropriate physical activity can significantly lower the risk of various diseases among middle-aged and older adults. Investigating optimal levels of physical activity (PA) is crucial for enhancing the health of this demographic. This study aims to explore the dose–response relationship between weekly PA levels and the frequency of colds among Chinese middle-aged and elderly individuals, identifying the necessary PA level to effectively diminish the risk of colds.

Methods
We conducted a cross-sectional study using a web-based survey targeting individuals aged 40 and older (n = 1, 683) in China. The survey collected information on PA and the frequency of colds. Data was analyzed using Kruskal–Wallis test and the χ2 test. We explored the dose–response relationship between weekly PA and cold frequency over the past year through an ordered multivariate logistic regression model and a restricted cubic spline model.

Results
(1) Brisk walking emerged as the preferred physical exercise for those over 40. The findings suggest that engaging in moderate (odds ratio (OR) = 0.64, P < 0.001, 95% confidence interval (CI) [0.50–0.81]) and high (OR = 0.64, P < 0.001, 95% CI [0.51–0.79]) levels of PA weekly significantly reduces the risk of catching a cold. Individuals with one (OR = 1.47, P < 0.001, 95% CI [1.20–1.80]) or multiple chronic diseases (OR = 1.56, P < 0.001, 95% CI [1.21–2.00]) were at increased risk. Those residing in central (OR = 1.64, P < 0.001, 95% CI [1.33–02.01]) and western China (OR = 1.49, P = 0.008, 95% CI [1.11–02.00]) faced a higher risk compared to their counterparts in eastern China. (2) According to the restricted cubic spline model, adults who experienced one cold in the past year had a weekly PA level of 537.29 metabolic equivalent-minutes per week (MET-min/wk) with an OR value of 1. For those reporting two or more colds, the PA level was 537.76 MET-min/wk with an OR of 1.

Conclusions
(1) Brisk walking is the most favored exercise among the Chinese middle-aged and elderly, with the prevalence of colds being affected by the number of chronic diseases and the geographic location. (2) Regular, moderate exercise is linked to a lower risk of colds. To effectively reduce cold frequency, it is recommended that middle-aged and elderly Chinese individuals engage in a minimum of 538 MET-min/wk of exercise.
SlZIP11 mediates zinc accumulation and sugar storage in tomato fruits
Authors: Sun Jiaqi , Wang Manning , Zhang Xinsheng , Liu Xin , Jiang Jing 
Published: May 2024

Background
Zinc (Zn) is a vital micronutrient essential for plant growth and development. Transporter proteins of the ZRT/IRT-like protein (ZIP) family play crucial roles in maintaining Zn homeostasis. Although the acquisition, translocation, and intracellular transport of Zn are well understood in plant roots and leaves, the genes that regulate these pathways in fruits remain largely unexplored. In this study, we aimed to investigate the function of SlZIP11 in regulating tomato fruit development.

Methods
We used Solanum lycopersicum L. ‘Micro-Tom’ SlZIP11 (Solanum lycopersicum) is highly expressed in tomato fruit, particularly in mature green (MG) stages. For obtaining results, we employed reverse transcription-quantitative polymerase chain reaction (RT-qPCR), yeast two-hybrid assay, bimolecular fluorescent complementation, subcellular localization assay, virus-induced gene silencing (VIGS), SlZIP11 overexpression, determination of Zn content, sugar extraction and content determination, and statistical analysis.

Results
RT-qPCR analysis showed elevated SlZIP11 expression in MG tomato fruits. SlZIP11 expression was inhibited and induced by Zn deficiency and toxicity treatments, respectively. Silencing SlZIP11 via the VIGS technology resulted in a significant increase in the Zn content of tomato fruits. In contrast, overexpression of SlZIP11 led to reduced Zn content in MG fruits. Moreover, both silencing and overexpression of SlZIP11 caused alterations in the fructose and glucose contents of tomato fruits. Additionally, SlSWEEET7a interacted with SlZIP11. The heterodimerization between SlSWEET7a and SlZIP11 affected subcellular targeting, thereby increasing the amount of intracellularly localized oligomeric complexes. Overall, this study elucidates the role of SlZIP11 in mediating Zn accumulation and sugar transport during tomato fruit ripening. These findings underscore the significance of SlZIP11 in regulating Zn levels and sugar content, providing insights into its potential implications for plant physiology and agricultural practices.

AbstractEncephalocraniocutaneous lipomatosis (ECCL) is a rare neurocutaneous syndrome characterized by involvement of tissues of ectodermal and mesodermal origin such as skin, eye, adipose tissue, and brain. Since 1970, when Haberland and Perou had described the first patient, 54 cases of ECCL have been reported in literature. We report on three new boys with ECCL. In addition to their typical dermal, ocular and central nervous system anomalies, one of them had a spheno‐ethmoidal osseous lesion. Histopathological evaluation confirmed the benign nature of the lesion and was consistent with fibrous dysplasia. The aim of our study is to review clinical records and brain imaging studies of these three new patients with ECCL and compare these findings with those reported in literature to better define the phenotypic spectrum and radiological findings in ECCL. © 2011 Wiley‐Liss, Inc.

AbstractWe describe a newborn female with a de novo interstitial deletion of chromosome 21q21.1‐22.12 including the RUNX1 gene who had developmental delay, multiple congenital anomalies, tetralogy of Fallot, anemia, and chronic thromobocytopenia requiring frequent platelet transfusions from birth. Because of her physical and hematologic abnormalities, she was tested for Fanconi anemia (FA). Lymphocytes and fibroblasts from this patient demonstrated increased chromosome breakage with exposure to the clastogen mitomycin C, but not, in contrast to most FA patients, to diepoxybutane. Further testing by Western analysis and complementation testing did not show a defect in the function of known Fanconi proteins. Her constitutional deletion was later found to span 13.2 Mb by chromosome microarray analysis, encompassing the RUNX1 gene that has been implicated in thrombocytopenia and predisposition to acute myelogenous leukemia (AML) when in the haploinsufficient state. We compare her phenotype to other individuals with similar 21q deletions and thrombocytopenia, as well as those with FA. We suggest that deletion of RUNX1 or another critical gene within the deleted region may result in chromosomal instability similar to that seen in FA. © 2011 Wiley‐Liss, Inc.

AbstractPartial trisomy 9p is one of the most common detected autosomal structural anomalies, so the phenotype–genotype correlation of this rearrangement has been well described. Despite variation in size of the 9p duplications, trisomy 9p syndrome is characterized by typical dysmorphic features and a variable but constant psychomotor and mental retardation. Previously reported phenotype genotype correlation studies proposed that the critical region for phenotype is located in 9p22. We report here on a new patient with partial trisomy 9p13.3→9pter in an 8‐year‐old boy with typical trisomy 9p dysmorphic features but a normal mental development. Cytogenetics investigations showed that our patient karyotype was 47,XY,+ der(22)t(9;22)(p13.q11) inherited by a 3:1 disjunction of a maternal reciprocal translocation t(9;22)(p13.q11). FISH and array CGH analysis were used to better characterize duplicated chromosomal regions and showed a large duplication of chromosome 9p13.3→9pter associated to microduplication in 22q11.1. The size of the duplications in chromosomes 9p and 22q were estimated about 33.9 and 2.67 Mb, respectively. The comparison between this case and those reported in the literature allows us to support that all syndromes show variability and that not all partial trisomies 9p are associated with intellectual disability. © 2011 Wiley‐Liss, Inc.
Determination of Molecular Surface Structure, Composition, and Dynamics under Reaction Conditions at High Pressures and at the Solid–Liquid Interface
Authors: Somorjai Gabor A. , Beaumont Simon K. , Alayoglu Selim 
Published: May 2011

AbstractIn the last two decades, surface‐science experiments and techniques have been developed to focus on obtaining molecular information under reaction conditions at high pressures (near or above 1 bar) and liquid interfaces. This Minireview describes the results of these studies obtained by surface‐sensitive laser spectroscopies, scanning tunneling microscopy, and X‐ray spectroscopies usually practiced at a synchrotron light source. The use of model surfaces, single crystals, and monodisperse nanoparticles with variable size (1–10 nm) and shape facilitates meaningful interpretation of the experimental data. These methods allow evaluation of the molecular structures of intermediates, oxidation states of metals, and mobility of adsorbants. New techniques that are likely to make major contributions to the investigation of surfaces under reaction conditions are also discussed.
Comparative study of PLA nanocomposites reinforced with clay and silica nanofillers and their mixtures

Published: May 2011

AbstractThis study compares the effects of two different types of nanosized fillers (silica and montmorillonite) at three different weight fractions as well their mixtures on the thermomechanical properties of polylactide (PLA). The role of aggregation and interphase was investigated in terms of several experimental techniques, including scanning electron microscopy, wide‐angle X‐ray scattering (WAXS), thermogravimetric analysis, differential scanning calorimetry, dynamic mechanical analysis (DMA), and tensile measurements. The experimental results clearly suggest that silica and montmorillonite have different reinforcing and toughening effects on PLA, while the combination of the two different nanofillers has a detrimental effect on the tensile properties of the material. Four micromechanics models describing the Young's modulus of the nanocomposites were used to study the different matrix–nanofiller interactions. The best fit of the experimental results was obtained with a model that assumes the presence of an interphase surrounding each nanoparticle. The increase of the nanofiller content above a certain amount was not accompanied by a corresponding increase of the interphase, because the total nanofiller surface area was counterbalanced by the creation of aggregates. It is postulated that the aggregation effect acts antagonistically to the interphase effect. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2011

AbstractThis article reports the synthesis, characterization and supercapacitative properties of dodecyl benzenesulphonic acid (DBSA) doped polyaniline(PAni) and its magnetite composites. The synthesized composites are characterized by Uv‐Vis, FT‐IR, XRD, SEM, electrochemical methods and are evaluated as electrode material for supercapacitor applications. The composites are partially soluble in methanol and are highly dispersible in water. The pristine polyaniline (PAni‐DBSA) showed a specific capacitance of 160 F/g, whereas its magnetite(3.8 wt %) composite (C1) and the symmetrical capacitor derived from C1 showed enhanced capacitance of 228 F/g and 180 F/g respectively, at 1 mA/cm2. © 2011 Wiley Periodicals, Inc.

Oxygen barrier and enthalpy of melting of multilayer EVOH films after pressure‐assisted thermal processing and during storage
Authors: Dhawan Sumeet , Barbosa‐Cànovas Gustavo V. , Tang Juming , Sablani Shyam S. 
Published: May 2011

AbstractPressure‐assisted thermal processing (PATP) is an advanced thermal process involving application of elevated pressures above 600 MPa on a preheated food for a holding time of 3 to 5 min, causing the volumetric temperature of food to increase above 100°C, to inactivate bacterial spores and enzymes. This study evaluated the influence of PATP on two state‐of‐the‐art multilayer EVOH films. Flexible pouches containing water as the food simulant were made from the two films and processed at 680 MPa for 3 min at 105°C and 680 MPa for 5 min at 100°C. Each film was investigated for its oxygen transmission rates (OTRs), melting temperature (Tm), enthalpy of melting (ΔH), and overall crystallinity before (control) and after processing. The changes in OTRs and total ΔH of the two films were also analyzed during a storage period of 240 days in ambient conditions after processing. Results showed a significant (P < 0.05) increase in the OTRs of the two films after PATP. However, PATP did not cause a significant (P > 0.05) change in the Tm and ΔH of the two films. The overall crystallinity of film A decreased, but improved slightly for film B after PATP. A recovery in the OTRs of the two films occurred during storage. The films also showed changes in the total ΔH measured during the storage period, which was used to explain the changes in the oxygen barrier properties. The OTR of both films remained below 2 cc/m2 day, which is required in packaging applications for shelf‐stable foods with a 1‐year shelf life. This work demonstrates the advantages of using multilayer films containing EVOH as the barrier layer in PATP applications to produce shelf‐stable foods. This work also highlights the advantage of, DSC analysis for studying the physical ageing of polymers during storage. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2011
Molecular cloning and characterization of two nicotinic acetylcholine receptor β subunit genes from Apis cerana cerana

Published: May 2011

AbstractNicotinic acetylcholine receptors (nAChRs) mediate fast cholinergic synaptic transmission in the insect nervous system and are important targets for insecticides. In this study, we identified and characterized two novel β subunit genes (Accβ1 and Accβ2) from Apis cerana cerana. Homology analysis indicated that Accβ1 and Accβ2 possess characteristics that are typical of nAChR subunits although Accβ2 was distinct from Accβ1 and the other nAChR subunits, due to its unusual transmembrane structure and uncommon exon–intron boundary within the genomic region encoding the TM1 transmembrane domain. Analysis of the 5′ flanking regions indicated that Accβ1 and Accβ2 possess different regulatory elements, suggesting that the genes might exhibit various expression and regulatory patterns. RT‐PCR analysis demonstrated that Accβ2 was expressed at a much higher level than Accβ1 in the tissues of adult bees. During development, Accβ1 was highly expressed at the pupal stages, whereas Accβ2 was abundantly expressed at the larval stages. Furthermore, Accβ1 and Accβ2 were both induced by exposure to various insecticides and environmental stresses although Accβ2 was more responsive than Accβ1. These results indicate that Accβ1 and Accβ2 may have distinct roles in insect growth and development and that they may belong to separate regulatory pathways involved in the response to insecticides and environmental stresses. This report is the first description of the differences between the nAChR β subunit genes in the Chinese honey bee and establishes an initial foundation for further study. © 2011 Wiley Periodicals, Inc.
Supercooled Sulfuric Acid Droplets: Perturbed Stratospheric Chemistry in Early Winter
Authors: Turco R. P. , Hamill P. 
Published: May 2011

AbstractDuring the onset of polar winter in the stratosphere, before the formation of nitric acid ice clouds (referred to as polar stratospheric clouds, or PSCs), sulfate aerosol particles may catalyze heterogeneous chemical reactions that redistribute chlorine from reservoir species to more active forms. This activated chlorine can lead to ozone destruction in the fall and early winter, prior to the formation of PSCs, at middle and high latitudes over the winter half‐year in both hemispheres. During periods of slow cooling, a significant fraction of ambient chlorine nitrate (ClONO2) may be processed into active chlorine through its reactions with water and HCl at the surfaces of dilute supercooled sulfuric acid droplets. This mechanism for chlorine activation may explain the occurrence of widespread regions of reduced ozone abundance in the Northern Hemisphere at high‐ and middle‐latitudes outside of the polar vortex. Following major volcanic eruptions, a large increase in the surface area of sulfate particles could lead to significant repartitioning of chlorine species via the reaction of ClONO2with H2O, even under midlatitude conditions, which may explain in part the detection of ozone reductions in volcanic clouds. Chemical transformation of other compounds may also be accelerated by the presence of dilute supercooled sulfate aerosols in the stratosphere, including the reaction of HOCl with HCl, and the hydrolysis of COF2to HF; however, neither of these latter processes appear to have first‐order significance for the chemistry of the stratosphere.
