Study of Some Immunological Parameters with Level of Iron in Women Infected with Trichomonas Vaginalis

Trichomonas vaginalis is a flagellated protozoan parasite that causes a disease called trichomoniasis inhumans. It affects the urogenital tract and is one of the most important causes of non-viral genitourinarysexually transmitted infection (STI). The host’s immune response plays a very important role in the onsetof pathological symptoms and their differences between infected people. During the period from July toDecember 2019, 30 samples were collected, 20 of infected women with T. vaginalis and 10 samples as acontrol group from reviews of external women’s clinics in Kirkuk city, whose ages ranged between 18-56 yearsso this study was designed to know the effect of infection with T. vaginalis parasite on some immunologicalparameters such as the role of humoral immune response based on the production of immunoglobulins IgM,IgG, IgA against the parasite and there estimation in serum by using Enzyme Linked Immunosorbent Assay(ELISA) technique as well as estimating the C-Reactive protein concentration as an indication of systemicinflammation and of serum iron level . The results of the current study showed a “significant” increase inthe level of immunoglobulins IgM, IgG in serum of women infected with T. vaginalis compared to thecontrol group, as the level of IgM (8. 2 ± 2.9 ng/dl), (6.3 ± 0.5 ng/dl) Consequently, at the level (p <0.05),the level of IgG was (8.16 ± 2.20 ng/dl), (6.53 ± 1.69 ng/dl) for the infected women and the control group,respectively. As for the level of IgA, the results showed non-significant increase in the affected womencompared with control group (8.22 ± 3.1 ng/dl), (7.82 ± 2.8 ng/dl), respectively. The results of estimatingthe CRP concentration showed a significant increase in the infected women compared to the control group(5.76± 1.56 mg/dl), (4.61± 0.66 mg/dl), respectively. While the results of measuring the level of iron showeda significant decrease among infected women and the control group (38.79 ±8.23 mg/dl), (93.83± 34.76 mg/dl), respectively. We conclude from the above that infection with T.vaginals stimulates the humoral immuneresponse and affects on immunoglobulins levels, CRP concentration and Iron serum level.
Förderung der Klassenführungskompetenzen von Lehramtsstudierenden unter Verwendung eines virtuellen Klassenzimmers

Klassenfuhrungskompetenzen sind bedeutsam fur professionelles Handeln von Lehrpersonen. Die systematische Forderung der Klassenfuhrungskompetenzen von Lehramtsstudierenden stellt ein Desiderat dar. Im vorliegenden Beitrag wird eine praxis- und theorieorientierte Entwicklung und Evaluation eines padagogischen Konzeptes zur Forderung der Klassenfuhrungskompetenzen von Lehramtsstudentinnen und -studenten in der Hochschullehre unter Verwendung eines vollimmersiven virtuellen Klassenzimmers vorgestellt. Auf der Basis einer Analyse theoretischer und empirischer Grundlagen zur Klassenfuhrung und zu padagogischen Konzepten zu deren Forderung unter besonderer Berucksichtigung der Potenziale von virtueller Realitat (VR) wird ein Konzept fur die Hochschullehre entwickelt. Im Konzept sind ein handlungsorientierter Ansatz und die Verwendung eines vollimmersiven Klassenzimmers bedeutsame Vorgehensweisen. Eine quasiexperimentelle Evaluationsstudie im Pra- und Posttestdesign bestatigt die hohere Wirksamkeit der Intervention im Vergleich zu einem handlungsorientierten Vorgehen ohne Einsatz eines virtuellen Klassenzimmers sowie zu einem Vorgehen, bei dem ausschliesslich die Erarbeitung von wissenschaftlicher Literatur zur Klassenfuhrung zum Einsatz kam.

Das Forschungsprojekt setzte es sich zum Ziel, das - basierend auf Bions Lernen durch Erfahrung (Bions 1992) - entwickelte Modell BIG (beobachten - interpretieren - gestalten) zu evaluieren und den moglichen Mehrwert fur den Professionalisierungsprozesses im Kontext schulpraktischer Studien aufzuzeigen. Gleichzeitig wurden die Beweggrunde der Lehrpersonen erfragt, die vorerst entschieden hatten, sich nicht an der Durchfuhrung des Modells zu beteiligen.
Quasi-Arithmetic Type Mean Generated by the Generalized Choquet Integral

It is known that the quasi-arithmetic means can be characterized in various ways, with an essential role of a symmetry property. In the expected utility theory, the quasi-arithmetic mean is called the certainty equivalent and it is applied, e.g., in a utility-based insurance contracts pricing. In this paper, we introduce and study the quasi-arithmetic type mean in a more general setting, namely with the expected value being replaced by the generalized Choquet integral. We show that a functional that is defined in this way is a mean. Furthermore, we characterize the equality, positive homogeneity, and translativity in this class of means.
Analytical study on Air India Traffic Using Artificial Neural Networks

In the past few years, Artificial Neural Networks (ANNs) have become more popular as a revolutionary approach to forecasting the time series. The present paper discusses Artificial Neural Networks to forecast air traffic. In this study, we developed an Artificial Neural Network (ANN) model to predict the air traffic of Air India by using a Multi-Layer Perceptron network. For this, we have considered the number of passengers traveling monthly in different seasons from January 2012 to December 2019 by air India domestic flights. The results provided through the model were entirely satisfactory.
Genome-wide association study of micronaire using a natural population of representative upland cotton (Gossypium hirsutum L.)

Background Micronaire is a comprehensive index reflecting the fineness and maturity of cotton fiber. Micronaire is one of the important internal quality indicators of the cotton fiber and is closely related to the value of the cotton fiber. Understanding the genetic basis of micronaire is required for the genetic improvement of the trait. However, the genetic architecture of micronaire at the genomic level is unclear. The present genome-wide association study (GWAS) aimed to identify the genetic mechanism of the micronaire trait in 83 representative upland cotton lines grown in multiple environments. Results GWAS of micronaire used 83 upland cotton accessions assayed by a Cotton 63 K Illumina Infinium single nucleotide polymorphism (SNP) array. A total of 11 quantitative trait loci (QTLs) for micronaire were detected on 10 chromosomes. These 11 QTLs included 27 identified genes with specific expression patterns. A novel QTL, qFM-A12–1 , included 12 significant SNPs, and GhFLA9 was identified as a candidate gene based on haplotype block analysis and on strong and direct linkage disequilibrium between the significantly related SNPs and gene. GhFLA9 was expressed at a high level during secondary wall thickening at 20∼25 days post-anthesis. The expression level of GhFLA9 was significantly higher in the low micronaire line (Msco-12) than that in the high micronaire line (Chuangyou-9). Conclusions This study provides a genetic reference for genetic improvement of cotton fiber micronaire and a foundation for verification of the functions of GhFLA9.
The Origin of the Transverse Radii of Hyperons at the LHC

Here we show that the effective Gaussian source radii for the proton-hyperon pairs obtained at the LHC follow from the atom-like structure of baryons which is described in the Scale-Symmetric Theory (SST). The effective radii strongly depend on the methods used, as has been proven with the proton.
Comparison of FRET microscopy imaging techniques for studying protein-protein interactions in living cells using FRET standards

Förster resonance energy transfer (FRET) microscopy is a powerful tool to localize protein-protein interactions in living specimens. Various FRET microscopy imaging techniques have been established and are generally categorized into intensity-based and lifetime-based methods. Based on the detection of the acceptor sensitized emission, we have developed the FRET imaging methodologies that can be applied in combination of wide-field, conventional confocal or spectral microscopy. All these FRET microscopy methods have the capability to interpret the change in proximity between the donor and the acceptor through measuring the apparent energy transfer efficiency (E). However, to answer what subtle change of E can be detected and to link correctly FRET data to biological information, the imaging techniques have to be well calibrated. In this regard, we compare various FRET microscopy methods and assess their utilities using several genetic ("FRET standard") constructs where Cerulean and Venus fluorescent proteins are tethered by different amino acid linkers.
Seroprevalence of Hepatitis B and C and Associated Risk Factors among HIV-1 Infected Patients in a High Risk Border Region of South West Cameroon

Background: Coinfection of HIV with human retroviruses such as hepatitis B (HBV) and hepatitis C (HCV) has been associated with adverse liver disease outcomes including reduced survival, cancer and antiretroviral induced hepatotoxicity. In this study, we evaluated the prevalence of hepatitis B surface antigen (HBsAg) and hepatitis C antibody (HCVAb) among HIV-infected individuals diagnosed within six months in South West Cameroon and identified risk factors of coinfection. Methods: We performed a systematic screening for HBsAg and HCVAb among 299 newly enrolled HIV-positive patients South West of Cameroon. Enzyme Linked Immuno-sorbent Assay (ELISA) confirmed the presence of HBV/HCV infection status. Risk factors of coinfection were assessed by logistic regression using SPSS V20 and Epi-Info v7. A P value < 0.05 was considered significant. Results: The overall prevalence of Hepatitis B/C was 16.05% with 12.0% (95% CI: 1.96-2.03) for HBV and 4% (95% CI: 1.97-2.02) for HCV. Participants in urban environment were less likely to be infected with HBV [aOR: 0.171 (0.044-0.660), P = 0.010] compared to rural environment. A history of blood transfusion increased odds of hepatitis B positivity six times [aOR: 5.8 (2.04-16.94), P = 0.001] and 13 times for hepatitis C [13.14 (3.04-56.81, P = 0.001]). Conclusions: The seroprevalence of hepatitis B and C among diagnosed HIV patients observed was 12% and 4% respectively. A history of blood transfusion was independently ORigiNAl ARTiCle
Sources and sinks of CF and CF2 in a cc-RF CF4-plasma under various conditions

In an asymmetric capacitively coupled radio-frequency (cc-RF) CF4 plasma, the radical densities of CF and CF2 were measured using laser-induced fluorescence spectroscopy. From the spatially (along the symmetry axis) and temporally (after switching off the discharge) resolved data, the source distribution and the sticking coefficients are inferred. We present results for three different electrode materials (stainless steel, aluminium and silicon). According to our data, the strength and the position of the sources depend strongly on the electrode material and the applied voltage. While the CF-sources are in the sheath in front of the powered electrode for stainless steel, they are on the surface of the powered electrode in the case of aluminium. By using a simple diffusion model for the analysis of the afterglow data, it can be shown that CF2 is destroyed exclusively at the walls and the decay time is determined by diffusion and sticking only. In contrast, for CF, surface as well as volume losses due to chemical reactions are important.
Origin of the low carrier lifetime edge zone in multicrystalline PV silicon

An investigation of impurities, crystal defects and microstructure has been performed on the edge zone, i.e. close to the crucible wall, which experiences reduced carrier lifetime in a directionally solidified multicrystalline p‐doped silicon ingot. The characterization methods applied have been QSSPC, FTIR, μW‐PCD, EBSD, CDI, PVScan, optical microscopy, FeB‐pair splitting and GDMS. The results of the minority carrier lifetime measurements have revealed strongly reduced values in the vicinity of the edge (< 1 μs). Increased values were obtained starting at 15–17 mm from the edge. Light elements analyses showed that the O, N and C concentrations, interstitially or in particles, did not increase in the edge zone, neither did the dislocation density. GDMS analyses detected traces of aluminium, iron, copper, titanium and chromium. The total iron concentration showed an increase towards the edge, though high concentrations were occasionally detected in the bulk. FeB pair analysis revealed large concentrations of Fe (∼1 × 1013 cm−3) in the vicinity of the edge with a distinctively decreasing trend moving away from the edge. The detected FeB‐concentrations are sufficient to account for the majority of the lifetime degradation close to the edge (0‐‐15 mm). In addition, Fe, in the form of FeB pairs, was extensively observed as object to internal gettering to high angle boundaries and dislocations. Fe, in the form of FeB pairs, is furthermore believed to originate from solid state diffusion from the crucible and coating. Copyright © 2008 John Wiley & Sons, Ltd.
Molecular statistical theory of nematic liquid crystals

Assuming a model based on permanent dipole-dipole, dispersion, induction and repulsion forces, the potential energy of a molecule in a nematic liquid crystal is derived as a function of its orientation. Analysis of the temperature variation of the degree of orientational order in p-azoxyanisole (PAA) and p-azoxyphenetole (PAP) indicates that the permanent dipole interactions are relatively unimportant. Making use of a mean field approximation, a statistical theory of long-range orientational order is developed and the thermodynamic properties of the ordered system are derived relative to those of the completely disordered one. Application of the theory to PAA and PAP shows conclusively that a certain degree of short-range orientational order is present in the liquid phase. Using just three parameters for each compound, viz. the two constants of the potential function and a numerical factor to allow for short range order, the following physical properties have been evaluated which are in quantitative agreement with the experimental data: the long-range orientational order parameter, specific heat and compressibility as functions of temperature in the liquid crystalline range, the latent heat and volume change at the nematic-isotropic transition point. The magnetic birefringence of the liquid phase affords an independent estimate of the short range order which supports the previous calculations.
Acute Megakaryocytic Leukemia with or Without Acquired Trisomy 21 in 15 Pediatric Patients

The knowledge of clinical characteristics and prognosis of pediatric acute megakaryocytic leukemia (AMKL) with or without acquired +21 was limited. We reported 15 AMKL pediatric patients without Down Syndrome (four cases with acquired +21 and 11 cases without acquired +21) with the clinical manifestations, laboratory data, and prognosis. The clinical features and laboratory data between patients with acquired +21 and patients without acquired +21 are similar. As for prognosis, three of the 11 cases without acquired +21 obtained complete remission (CR) after 1st induction. The median follow-up time of the 11 cases was 9 months. Among four cases with acquired +21, one case gave up treatment during 1st induction, one obtained CR after 1st induction and was still alive after 49 months of follow-up. One case obtained CR after 2nd induction and was still alive for 15 months of follow-up after bone marrow transplantation, the other patient was planning for allogeneic hematopoietic stem cell transplantation (HSCT) without CR. The median follow-up time of the four cases was 12 months. None relapsed in our study. In conclusion, acquired trisomy 21 may not be an indicator for poor prognosis. Cytogenetics analysis can help us for diagnosis stratification, prognostic judgment and individualized treatment of AMKL.
Mixed versus Focused Resistance Training during an Australian Football Pre-Season

The purpose of this investigation was to determine the effect of a focused versus mixed-methods strength-power training plan on athletes undertaking high volumes of concurrent training. Fourteen junior elite male Australian football players were randomly assigned into either the focused or mixed group. Both training groups undertook a sequenced training intervention consisting of a four-week mesocycle emphasising heavy strength followed by a four-week mesocycle of high velocity emphasis. Training differed between groups by way of the degree of emphasis placed on the targeted attribute in each cycle and occurred during the preseason. Testing occurred pre- and post-training and consisted of the unloaded and loaded (+20 kg) countermovement jump (CMJ). Focused training elicited practical (non-trivial) improvements in flight time to contraction ratio (FT:CT) (g = 0.45, ±90% confidence interval 0.49) underpinned by a small reduction in contraction time (g = −0.46, ±0.45) and a small increase in braking (g = 0.36, ±0.42) and concentric phase mean force (g = 0.22, ±0.39). Conversely, the mixed group demonstrated an unchanged FT:CT (g = −0.13, ±0.56). Similar respective changes occurred in the loaded condition. Preferential improvements in FT:CT occur when a greater focus is placed on a targeted physical quality in a sequenced training plan of junior elite Australian football players during preseason training.
Separation of titanium from silicates for isotopic ratio determination using multiple collector ICP-MS

A new separation method of Ti from silicate materials is presented that is suitable for the determination of natural Ti isotope variations using multi-collector inductively coupled plasma source mass spectrometry (MC-ICP-MS). This method makes possible for the first time the separation of Ti from natural materials, with high purity, high recovery and no introduction of artificial mass fractionation. Following sample decomposition using HF, Ti is separated using a three-column procedure. In the first column using an anion-exchange resin, AG 1X8, major elements and the majority of trace elements are separated. In the second column, after eliminating F− by evaporation with HClO4 and re-dissolution with H2O2–HNO3, Ti is separated from Zr and Hf using a liquid–liquid extraction resin, U/TEVA. In the third column, which is the same as the first column, trace amounts of Al and P are further removed. Recovery yields were almost unity, and no Ti isotope fractionation occurred from the overall chemical processing. The reproducibilities (2σ) of the Ti isotope ratio measurement for a meteorite (eucrite) and a lamproite were <0.5e for e47Ti, e48Ti and e49Ti, and <1e for e50Ti, which were comparable to those for the pure Ti standard solution.
Magic number behavior for heat capacities of medium-sized classical Lennard-Jones clusters

Monte Carlo methods were used to calculate heat capacities as functions of temperature for classical atomic clusters of aggregate sizes 25⩽N⩽60 that were bound by pairwise Lennard-Jones potentials. The parallel tempering method was used to overcome convergence difficulties due to quasiergodicity in the solid-liquid phase-change regions. All of the clusters studied had pronounced peaks in their heat capacity curves, most of which corresponded to their solid-liquid phase-change regions. The heat capacity peak height and location exhibited two general trends as functions of cluster size: for N=25 to 36, the peak temperature slowly increased, while the peak height slowly decreased, disappearing by N=37; for N=30, a very small secondary peak at very low temperature emerged and quickly increased in size and temperature as N increased, becoming the dominant peak by N=36. Superimposed on these general trends were smaller fluctuations in the peak heights that corresponded to “magic number” behavior, with local max.

Healthy Lifestyle Physical Education Teachers Based on Physical Activity and Body Mass Index

It has become a global agreement if physical education (PE) in schools aims to promote physical activity (PA). The PE teacher as a promoter, should have active lifestyle to be an example of what is promoted. However, the PE teacher's body shape is still not ideal, the question is, what is their PA? This article aims to identify the healthy lifestyle of PE teachers based on PA and body mass index (BMI). This study uses a cross-sectional study design. 46 PE teachers became research subjects. PA was measured using an international physical activity questionaire (IPAQ-short form) while BMI was determined by weight and height. Data analysis uses descriptive statistics, correlations, and t-tests. The results show that PE teachers are active (M= 5,196 MET-Minutes/Week). Based on BMI, 43% of teachers have an overweight and 57% are ideal. There was no relationship between BMI and PA [X(1)= 1.035, p= 0.309, r= 0.15]. In addition, teacher status (as exathlete and non-athlete) did not affect PA [t(44)= -1.653, p= 0.106] and BMI [t(44)= -0.495, p= 0.623]. It was concluded that PA is not a variable that affects BMI, both are not influenced by PE teacher status in the past as athletes.
