Cervical cancer knowledge and attitude among a cohort of female schoolteachers in Salem city – A cross-sectional survey

The present study aimed to assess the knowledge and attitude of female schoolteachers toward cervical cancer. Materials and Method: A cross-sectional study was conducted among 256 Government female schoolteachers aged 22–60 years in Salem city, Tamil Nadu. A self-administered questionnaire which assessed the levels of knowledge (6 items) and attitude (4 items) regarding cervical cancer was employed and responses were recorded on a three-point Likert scale. Data were analysed using Statistical Package for Social Sciences (SPSS) software version 20.0. Results: Overall adequate knowledge and good attitude regards to cervical cancer was observed among 60% and 66.8% of schoolteachers, respectively. Participants in the age range of 31–45 years (p = 0.007), primary schoolteachers (p = 0.004) and Hindus (p = 0.001) displayed significantly adequate levels of knowledge compared to their respective counterpart. Likewise, based on attitude subjects possessing postgraduation (p = 0.001) and middle schoolteachers (p = 0.009) had significant good attitude scores. Significant linear correlation was observed knowledge with class teacher (r = 0.136, P = 0.03) and religion (r = 0.208, P = 0.001) whereas attitude with qualification (r = 0.165, P = 0.008) and class teacher (r = 0.206, P = 0.001) which are positive predictors. Moreover, knowledge had a significant positive correlation with attitude (r = 1.000, P = 0.000). Conclusion: Primary care physicians partnering network with schoolteachers having adequate knowledge and good attitude acts as a workforce to support cervical cancer screening and human papillomavirus vaccination.
Dynamic Modeling of Multivariate Counts - Fitting, Diagnostics, and Applications

An adequate statistical methodology is required for modeling multivariate time series of counts. The proper specification of the underlying distribution in such modeling could be very challenging, as it should account for the possibility of overdispersion, an excessive number of zero values, positive and negative association between counts, etc. This dissertation is focused on modeling multivariate time series of counts as a function of location-specific and time-dependent covariates. The Bayesian framework for estimation and prediction is discussed. We focus on Markov chain Monte Carlo (MCMC) methods for fully Bayesian inference and the Integrated Nested Laplace Approximation (INLA) for fast implementation of approximate Bayesian modeling which is especially useful for large data sets. The dissertation has three main contributions. First, we propose a dynamic model that combines time series compositional modeling with dynamic modeling for counts. This approach is applied to the problem of transportation engineering. We investigate the temporal behavior of injury severity levels as proportions of all pedestrian crashes in each month, taking into consideration effects of time trend, seasonal variations and Volodymyr Serhiyenko – University of Connecticut, 2015 VMT (vehicle miles traveled). Second, this dissertation discusses a hierarchical multivariate dynamic modeling framework. The use of a multivariate Poisson (MVP) sampling distribution is discussed. We show that the use of such distribution enables us to model the association between components of the multivariate response vector over time. This approach is illustrated using data from ecology on gastropod abundance in Puerto Rico. Finally, we propose a level correlated model (LCM) to account for the association among the components of the response vector. This multivariate model accounts for overdispersion as well as for positive and negative association between counts. The flexible LCM framework allows us to combine different marginal count distributions and to build a dynamic model for the vector time series of counts. We comprehensively discuss the lower and upper limits for the association between the components of the response vector of counts. We employ the proposed modeling to ecology and marketing examples and discuss the results. Dynamic Modeling of Multivariate Counts – Fitting, Diagnostics, and Applications Volodymyr Serhiyenko M.S.

Cytogenetic study of five species of medicinal plants from Maha Sarakham Province, Thailand

Abstract. Saensouk S, Saen-in N, Saensouk P. 2022. Cytogenetic study of five species of medicinal plants from Maha Sarakham Province, Thailand. Biodiversitas 23: 3593-3603. The cytogenetic study of five species of medicinal plants, namely Butomopsis latifolia (D. Don) Kunth, Iris domestica (L.) Goldblatt & Mabb. , Limnocharis flava (L.) Buchenau, Murdannia loriformis (Hassk.) R.S. Rao & Kammathy, and Pontederia hastata L. from Maha Sarakham Province, northeastern Thailand was conducted. This study aimed to investigate the chromosome numbers, fundamental number (NF), karyotype forms, and perform ideogram analysis of the five species. The cytogenetic characteristics, including the chromosome number, karyology (fundamental number (NF), karyotype formula), symmetrical karyotype, chromosome size, relative length (RL), centromeric indexes (CI), and ideograms of B. latifolia (D. Don) Kunthwere studied for the first time. The chromosome numbers of five medicinal plant species were reported as 2n = 14 (B. latifolia (D. Don) Kunth)- 80 (I. domestica (L.) Goldblatt & Mabb. ). Moreover, the NF had 28 (B. latifolia (D. Don) Kunth) - 80 (Iris domestica). Two species (M. loriformis(Hassk.) R.S. Rao & Kammathyand P. hastata L. ) were recognized as having symmetrical karyotypes. Three species, namely B. latifolia (D. Don) Kunth, Iris domestica, and L. flava(L.) Buchenau were reported as having asymmetrical karyotypes. Chromosomes of large size (L), chromosomes of medium size (M), and chromosomes of small size (S) were observed. Ideograms of five species were provided in this study. The NF, RL, CI, chromosome size, and ideograms of all species were reported for the first time in this study. The karyotype formulae of the five species, except the karyotype formula of P. hastata L. , differed from those previously studied. The cytogenetic data of the five species in this study can be used for identification.
Homogeneous Spatial Distribution of Deuterium Chemisorbed on Free-Standing Graphene

Atomic deuterium (D) adsorption on free-standing nanoporous graphene obtained by ultra-high vacuum D2 molecular cracking reveals a homogeneous distribution all over the nanoporous graphene sample, as deduced by ultra-high vacuum Raman spectroscopy combined with core-level photoemission spectroscopy. Raman microscopy unveils the presence of bonding distortion, from the signal associated to the planar sp2 configuration of graphene toward the sp3 tetrahedral structure of graphane. The establishment of D–C sp3 hybrid bonds is also clearly determined by high-resolution X-ray photoelectron spectroscopy and spatially correlated to the Auger spectroscopy signal. This work shows that the low-energy molecular cracking of D2 in an ultra-high vacuum is an efficient strategy for obtaining high-quality semiconducting graphane with homogeneous uptake of deuterium atoms, as confirmed by this combined optical and electronic spectro-microscopy study wholly carried out in ultra-high vacuum conditions.
Reference Values of Spatial and Temporal Gait Parameters in a Contemporary Sample of Spanish Preschool Children: A Cross-Sectional Study

The aim of this study was to analyze the influence of age and sex on kinematic gait parameters in preschool children, and derive reference values for this population. A total of 383 preschool children (age 3–5 years; 207 girls, 176 boys) participated in this study. We used the OptoGait system to assess the kinematics of gait at a comfortable and self-determined speed. No significant differences between the sexes were found for the main gait parameters. Among the participants, there was a significant increase in double support, reductions in absolute cadence and the coefficient of variation (CV) of cadence, an increase in absolute step length (SL), and an increase in the walk ratio (WR) from 3 to 5 years of age. However, the normalized SL and normalized WR displayed a significant reduction in both sexes. Partial correlation indicated a significant association of age with SL and normalized SL, and WR. Additionally, WR showed a significant correlation with the CV of cadence. To summarize, no relevant differences in gait performance were found according to sex; however, age was found to influence gait maturation. The normative values established for Spanish preschool children can be used to monitor healthy gait development.
Metformin, Statin Use, and Female Colorectal Cancer: A Population-Based Cohort Study in Taiwan

In the last few years, the incidence of colorectal cancer (CRC) in women has gradually increased. However, epidemiological studies on the relationship between type II diabetes mellitus (T2DM) and female CRC and the effect of metformin or statins on female CRC are insufficient. To determine their association, we conducted a population-based cohort study on women in Taiwan. We collected data on a total of 396,521 women aged 40 to 64 years old from 1 January 2007 to 31 December 2009 from the National Health Insurance Research Database. We followed up on all participants in the cohort until the occurrence of CRC, the date for all death, or 31 December 2015. Full development of CRC was identified using the International Classification of Disease (ICD), 9th Revision, code 153. We estimated hazard ratios (HRs) and corresponding 95% confidence intervals (CIs) using the Cox proportional hazards model. Both metformin (adjusted hazard ratio, aHR = 1.12; 95% CI: 0.934–1.335, p = 0.227) and statin (aHR = 1.03; 95% CI: 0.906–1.172, p = 0.645) use showed no association with female CRC in a multivariate analysis. The findings indicate that metformin and statin use showed no protective effect against female colorectal cancer (CRC). An additional randomized trial is necessary to investigate the effect of metformin and statin use in CRC prevention.
Increased T-bet/GATA-3 and ROR-γt /Foxp3 Ratios in Cerebrospinal Fluid as Potential Criteria for Definite Neuro-Behçet’s Disease

When the central nervous system (CNS) is the primary affected site in an initial attack of Behçet’s disease (BD), the differential diagnosis is particularly challenging. Some cases remain unclassified or qualified as probable neuro-Behçet’s disease (NBD). Several cytokines are involved in the immunopathogenesis of this disease; however, studies establishing the differential cytokine pattern between probable and definite NBD are scarce. Twenty-eight parenchymal NBD patients, diagnosed according to the International Consensus Recommendation (ICR) criteria and classified into definite (D-NBD; n = 17) and probable (P-NBD; n = 11), were sampled at their first neurological symptoms, and compared with healthy control subjects (n = 20). Oligoclonal bands (OCB) of IgG were detected by isoelectric focusing on agarose, and immunoblotting of matched serum and cerebrospinal fluid (CSF) sample pairs. T cell cytokines (INF-γ, IL-4, IL-17, and IL-10) and transcription factors related to Th1, Th2, Th17, and T regulatory populations (respectively T-bet, GATA-3, ROR-γt, and Foxp3) were studied by quantitative RT-PCR in peripheral blood mononuclear cells (PBMCs) and CSF cells. Inflammatory cytokines such as IL-6, TNF-α, and IL-1β were also analyzed. CSF OCB pattern 2 was present in only 1 out of 28 neuro-Behçet’s patients who belonged to the P-NBD group. Two D-NBD patients had OCB in CSF showing pattern 4. In the D-NBD CSF samples, IL-17 and IL-10 expressions were significantly elevated compared to P-NBD. Moreover, D-NBD patients had increased levels of T-bet/GATA-3 and ROR-γt/Foxp3 ratios compared to P-NBD. Furthermore, a significant increase of CSF IL-6 in D-NBD, compared to P-NBD and the controls, was found. In addition to the increased IL-6 level, the data obtained suggest the existence in D-NBD patients of a significantly disrupted balance between Th17 effector and T regulatory cells, as reflected by the enhanced ROR-γt/Foxp3 ratio. This could be considered as an additional criterion for definite neuro-Behçet’s disease.
Chicken Gut Microbiota Responses to Dietary Bacillus subtilis Probiotic in the Presence and Absence of Eimeria Infection

Coccidiosis is a well-known poultry disease that causes the severe destruction of the intestinal tract, resulting in reduced growth performance and immunity, disrupted gut homeostasis and perturbed gut microbiota. Supplementation of probiotics were explored to play a key role in improving growth performance, enhancing innate and adaptive immunity, maintaining gut homeostasis and modulating gut microbiota during enteric infection. This study was therefore designed to investigate the chicken gut whole microbiota responses to Bacillus subtilis (B. subtilis) probiotic feeding in the presence as well as absence of Eimeria infection. For that purpose, 84 newly hatched chicks were assigned into four groups, including (1) non-treated non-challenged control group (CG − ET), (2) non-treated challenged control group (CG + ET), (3) B. subtilis-fed non-challenged group (BS − ET) and (4) B. subtilis-fed challenged group (BS + ET). CG + ET and BS + ET groups were challenged with Eimeria tenella (E. tenella) on 21 day of housing. Our results for Alpha diversity revealed that chickens in both infected groups (CG + ET and BS + ET) had lowest indexes of Ace, Chao 1 and Shannon, while highest indexes of Simpson were found in comparison to non-challenged groups (CG − ET and BS − ET). Firmicutes was the most affected phylum in all experimental groups following Proteobacteria and Bacteroidota, which showed increased abundance in both non-challenged groups, whereas Proteobacteria and Bacteroidota affected both challenged groups. The linear discriminant analysis effect size method (lEfSe) analysis revealed that compared to the CG + ET group, supplementation of probiotic in the presence of Eimeria infection increased the abundance of some commensal genera, included Clostridium sensu stricto 1, Corynebacterium, Enterococcus, Romboutsia, Subdoligranulum, Bacillus, Turicibacter and Weissella, with roles in butyrate production, anti-inflammation, metabolic reactions and the modulation of protective pathways against pathogens. Collectively, these findings evidenced that supplementation of B. subtilis probiotic was positively influenced with commensal genera, thereby alleviating the Eimeria-induced intestinal disruption.
possible role of high risk HPV infection and RPD3 overexpression in Iraqi patients with colorectal cancer

Aims: the aim of this study is RPD3 expression in clinicopathological characteristics in CRC patients and to study the existence of a relationship between CRC and HPV in samples of Iraqi patients. Material and methods: 30 samples of formalin-fixed, paraffin-embedded archival tissues from CRC patients were obtained, together with 10 samples of normal tissue (free cancer), for immunohistochemical analysis of RPD3 and HPV expression. Results: Immunohistochemical (IHC) staining revealed only four cases (15%) with HPV infections while PRD3 was expressed in 19 CRC samples (63.3 percent). The PRD3 expression ratio. It was found in only four (15%) of the CRC samples. At ≤ P 0. 05, there is no significant difference. Conclusion: The results of this study support RPD3 as a supplementary marker to identified histologic screening components; it could possibly be used for the prognosis and targeted therapy. In addition, we discovered a relation with both HPV infection and CRC as oncovirus and tumorigenic factor.
Adolescent social emotional skills, resilience and behavioral problems during the COVID-19 pandemic: A longitudinal study in three European countries

Objectives The consequences of long-lasting restrictions related to the COVID-19 pandemic have become a topical question in the latest research. The present study aims to analyze longitudinal changes in adolescents’ social emotional skills, resilience, and behavioral problems. Moreover, the study addresses the impact of adolescents’ social emotional learning on changes in their resilience and behavioral problems over the course of seven months of the pandemic. Methods The Time 1 (T1) and Time 2 (T2) measuring points were in October 2020 and May 2021, characterized by high mortality rates and strict restrictions in Europe. For all three countries combined, 512 questionnaires were answered by both adolescents (aged 11-13 and 14-16 years) and their parents. The SSIS-SEL and SDQ student self-report and parent forms were used to evaluate adolescents’ social emotional skills and behavioral problems. The CD-RISC-10 scale was administered to adolescents to measure their self-reported resilience. Several multilevel models were fitted to investigate the changes in adolescents’ social emotional skills, resilience, and behavioral problems, controlling for age and gender. Correlation analysis was carried out to investigate how changes in the adolescents’ social emotional skills were associated with changes in their resilience and mental health adjustment. Results Comparing T1 and T2 evaluations, adolescents claim they have more behavioral problems, have less social emotional skills, and are less prosocial than perceived by their parents, and this result applies across all countries and age groups. Both informants agree that COVID-19 had a negative impact, reporting an increment in the mean internalizing and externalizing difficulties scores and reductions in social emotional skills, prosocial behavior, and resilience scores. However, these changes are not very conspicuous, and most of them are not significant. Correlation analysis shows that changes in adolescents’ social emotional skills are negatively and significantly related to changes in internalized and externalized problems and positively and significantly related to changes in prosocial behavior and resilience. This implies that adolescents who experienced larger development in social emotional learning also experienced more increase in resilience and prosocial behavior and a decrease in difficulties. Conclusion Due to its longitudinal design, sample size, and multi-informant approach, this study adds to a deeper understanding of the pandemic’s consequences on adolescents’ mental health.
Improving Representation Over Time? Assessing Intersectional (In)Visibility of Masculinity and Race/Ethnicity in Print Ads

Abstract The current research investigates intersections of masculinity and race/ethnicity as portrayed in mainstream advertisements by assessing 1,181 print ads across two time periods. Drawing on intersectionality and content analysis, the intersections of masculinity types and race/ethnicity are explored. Results suggest a narrow assessment of these elements as part of diversity can lead to false improvement assumptions over time. Rather than focusing on one intersection such as masculinity, multiple dimensions should be considered to more accurately capture developments within advertising over time. Overall, companies need to reevaluate how diversity is reflected in advertisements and select suitable depictions to fully reflect and advance societal diversity in promotional tools.
A bio‐inspired backbone formation protocol in cognitive radio networks

The cognitive radio network (CRN) is an emerging technology where communication among secondary users (SUs) takes place in an opportunistic manner. Since, a backbone eases the routing, reduces communication overhead, and efficiently handles the dynamic changes in the network. Therefore, we intend to propose a backbone formation algorithm in CRN. However, finding optimal backbone is equivalent to find minimum connected dominating set (CDS) for the given network, which is NP‐complete. Hence, the backbone construction problem can be better handled by optimization algorithms than the deterministic ones. The bio‐inspired is an interesting category of optimization algorithms. Therefore, it has been popularly used to handle various optimization problems in wireless networks. However, it has never been used for backbone construction in CRN. The ant colony optimization (ACO) is a promising bio‐inspired method because it has been effectively used to handle many problems in wireless networks, e.g. cluster head selection, leader election, routing etc. Therefore, we use ant colony system (ACS) for backbone formation in CRN. Also, the approach helps us to find optimized path between any pair of nodes to ensure efficient communication. To the best of our knowledge, it is the first bio‐inspired backbone construction algorithm in CRN.
NONLINEAR TRAVELLING WAVE SOLUTIONS IN SQUARE DUCT FLOW

Incompressible viscous flow through a straight duct with a square cross section driven by a constant pressure gradient is believed to be linearly stable as in the case of pipe flow and plane Couette flow. Therefore, there exists no solution which bifurcates from the laminar state and the transition to turbulence is abruptly caused by a finite amplitude disturbance. The turbulent state for these flows is considered to be represented by the trajectory in the phase space wandering around unstable nonlinear solutions, which are disconnected to the laminar state. While a number of nonlinear solutions have been published in pipe flow and plane Couette flow, only three nonlinear solutions have been reported so far in square duct flow (Wedin et al., Phys. Rev. E 79, 065305, 2009; Uhlmann et al., Phys. Fluids 22, 084102, 2010; Okino et al., J. Fluid Mech. 657, 413-429, 2010). In this thesis, a number of nonlinear travelling wave solutions in square duct flow are presented. The first solution is discovered by a continuation approach from internally heated flow. The linear stability shows this solution is unstable from its onset. The next two solutions emerge from the first one via symmetry breaking bifurcations. We find one of them seems to be embedded in the laminar-turbulent boundary. The others are obtained by a continuation method using artificial body forces, which is invented by Waleffe, Phys. Rev. Lett. 81, 4140-4143 (1998). The richness of the nonlinear solutions implies the complexity of the phase space and these solutions are expected to be the fundamental building blocks of turbulence in a square duct. Moreover, striking similarity between the solutions in square duct flow and pipe flow is shown throughout the thesis.
