An Assessment for the Using Pollen Allergenic Woody Plants in Landscape Design: the Case of Ankara
Authors: Corbaci Omer Lutfu 
Published: January 2023

AbstractMistakes made in the design of urban green areas and in the selection of ornamental plants cause pollen allergy, which is one of the most common diseases in urban populations. This study assesses the pollen characteristics and allergenic effects of the species of woody trees, shrubs, and bushes planted in urban green areas in Ankara city center in the context of landscape architecture activities. A list of plant species with allergenic pollen is drawn up, together with their flowering periods and other relevant properties, and a number of points are identified to be taken into consideration for reducing the effects of pollen allergic plants and for planning and designing healthy green areas. Although there are many studies on allergenic plants in Turkey, studies on the use of allergenic plants in urban design have been rare. For this reason, the present study also addresses essential principles for reducing the effects of allergenic plants in design and for planning and designing healthy green areas. The study will be beneficial both for the environment and for the creation of green areas sensitive to human health.

Published: January 2023

Abstract
Introduction: Pelvic organ prolapse affects women’s quality of life in various aspects. However, the evidence on their healthcare-seeking behavior is limited. Therefore, this study aimed to review and synthesize the existing evidence on the healthcare-seeking behavior among women with pelvic organ prolapse.
Methods: The electronic databases PubMed, African Journals Online, Cumulative Index to Nursing and Allied Health Literature, African Index Medicus and Directory of Open Access Journal and Google Scholar were searched for relevant literature. The retrieved evidence was synthesized using narrative synthesis approach. The characteristics of included studies and the level of healthcare-seeking behavior were summarized in a table and texts. Error bar was used to show the variability across different studies.
Results: A total of 966 articles were retrieved among which only eight studies with 23,501 women (2,683 women with pelvic organ prolapse) were included in the synthesis. The level of healthcare-seeking behavior ranges from 21.3% in Pakistan to 73.4% in California, USA. The retrieved studies were conducted on four different study populations, used both secondary and primary data, and were conducted in six different countries. Error bar shows a variation in the percentage of healthcare-seeking behavior.
Conclusions: The level of Health-care seeking behavior among women with pelvic organ prolapse is low in low-income countries compared to high income countries. The characteristics of the reviewed studies are very different from each other. We recommend a large-scale study with a sub-group analysis which will help to understand the healthcare-seeking behavior.
Adaptive controller with fixed-time convergence for combination synchronisation of multiple master and slave chaotic systems
Authors: OUAHABI Rabiaa 
Published: January 2023

Abstract
This paper mainly studies the fixed-time combination synchronization between different multiple chaotic systems using adaptive control. Asymptotic chaos combination synchronization has previously been considered, but the fixed-time combination synchronisation of multiple chaotic systems in the presence of uncertain parameters, it is the first of its kind. The fixed time control and adaptive control algorithms are successfully included to realize the combination synchronization between different multiple chaotic systems. Among the advantages of the proposed scheme is the possibility of realizing synchronization between almost all different chaotic and even hyper-chaotic systems in a short fixed time. According to the Lyapunov theory, and fixed time laws, the uncertain parameters are estimated and the settling time is calculated. Numerical simulation results are presented to prove the effectiveness of the proposed scheme.

Published: January 2023

Abstract
Single-site catalysts (SSCs) have attracted significant research interest due to their high metal atom utilisation. Platinum single sites trapped in the defects of carbon substrates (trapped Pt-SSCs) have been proposed as efficient and stable electrocatalysts for the hydrogen evolution reaction (HER). However, the correlation between Pt bonding environment, its evolution during operation and catalytic activity is still unclear. Here, a trapped Pt-SSC is synthesised by pyrolysis of H2PtCl6 chemisorbed on a polyaniline substrate. In-situ heated scanning transmission electron microscopy and temperature-dependent X-ray photoelectron spectroscopy clarify the thermally-induced structural evolution of Pt during pyrolysis. The results show that the nitrogen in polyaniline coordinates with Pt ions and atomically disperse them before pyrolysis and trap Pt sites at pyridinic N defects generated during the substrate graphitisation. Operando X-ray absorption spectroscopy confirms that the trapped Pt-SSC is stable at the HER working potentials but with inferior electrocatalytic activity compared to metallic Pt nanoparticles. First principle calculations suggest that the inferior activity of trapped Pt-SSCs is due to their unfavourable hydrogen chemisorption energy relative to metallic Pt nanoparticles. These results further the understanding of the structure-property relationship in trapped Pt-SSCs and motivates a detailed techno-economic analysis to evaluate their commercial applicability.

Published: January 2023

Abstract

Background:Chordomas are low-grade, locally invasive, frequently recurring, malignant bone tumor with poor prognosis. Cervical chordoma in adults is rare and often missed when patients present with cervical radiculopathy. They can mimic other malignant tumors and, hence require histologic distinction for prognostic risk stratification and optimal treatment.
Case Report:We present a 61-year-old male with chronic neck pain and sensory neuropathy in bilateral upper limbs. The patient underwent cervical discectomy and fusion which revealed a cystic mass arising from the right neural foramina at C5-C6 level. Histopathological examination of the mass was consistent with chordoma.
Conclusion:Elderly patients with cervical radiculopathy should be evaluated for neoplasia including chordoma and differentiated from other etiologies. Early diagnosis and treatment can reduce morbidity and mortality from chordoma.
Convergent avialan brain morphology in Sinovenator (Troodontidae, Theropoda)
Authors: Yu Congyu , Watanabe Akinobu , Qin Zichuan , King Logan , Witmer Lawrence , Ma Qingyu , Xu Xing 
Published: January 2023

Abstract
Multiple modifications to the skull and brain anatomy occurred along the lineage encompassing bird-line theropod dinosaurs and modern birds. Anatomical changes to the endocranium include an enlarged endocranial cavity, relatively larger optic lobe that implies elevated visual acuity, and proportionately smaller olfactory bulbs that suggests reduced olfaction. Here, we use micro-computed tomographic (CT) imaging to reconstruct the endocranium and its brain structures from an exceptionally well-preserved skull of Sinovenator changii (Troodontidae, Theropoda). While its overall morphology resembles the typical endocranium of other troodontids, Sinovenator also exhibits unique endocranial features that are similar to other paravian taxa and non-maniraptoran theropods. Landmark-based geometric morphometric analysis on endocranial shape of non-avialan and avian dinosaurs points to the overall brain morphology of Sinovenator most closely resembling that of Archaeopteryx, thus indicating convergent evolution of avialan brain morphology in troodontids and wide existence of such architecture in Maniraptora.

Fast geometry-based ambiguity resolution algorithm for real-time kinematic
Authors: Castan Thibaut 
Published: January 2023

Abstract

Centimeter-level positioning using real-time kinematic technology is achievable only after overcoming the step of ambiguity resolution. Fast algorithms providing such a solution tend to have low success rates, often resulting in time to first fix too long in many real-life cases. On the other hand, other algorithms, such as the LAMBDA method, provide a better success rate at the expense of more computations. The recent growth in the number of constellations available for positioning along with the multiplication of signals per satellite is challenging slower algorithms which prove to have a complexity exponential with the number of signals. This article presents a new approach to the integer ambiguity problem, showing in an experiment a success rate of 100% with a computational speed ten times higher than the MLAMBDA algorithm, the complexity of the search process being O(n2) with n the total number of signals. We consider here a short baseline model to introduce the algorithm. It is straightforward to extend the results to longer baselines using a more complete model, as the hypotheses for the algorithm to be successful are made explicit along the article. Classical techniques developed to improve ambiguity resolution, as well as computational tricks could be used to further improve the speed of this algorithm, and could hence lead to improved time to first fix in low-cost embedded equipment.

Published: January 2023

Abstract
The actual gear mesh process is dynamic and the driving speed is of a great significance for dynamic response, while its nonlinear effect in the evaluation of mesh stiffness has commonly ignored by many scholars. In this paper, a new nonlinear dynamic model for spur gear system considering dynamic force increment, together with the effect of velocity-dependent mesh stiffness is developed to obtain the dynamic response. An original computational algorithm for calculating velocity-dependent mesh stiffness based on analytical-FEM framework is proposed, whose correction is verified by finite element method. The steady-state solution of the gear system is studied analytically by numerical simulations. Changes in the dynamic responses in the time/frequency domains using the driving speed as the control parameter are examined, and the nonlinear relationship between the driving speed and the time-varying mesh stiffness is demonstrated. Numerical results are presented to illustrate and quantify the influence of velocity-dependent mesh stiffness and dynamic force increment on the dynamic characteristics of the spur gear system. The results presented in this study demonstrate the reasonable accuracy of velocity-dependent mesh stiffness, and provide a theoretical basis for the follow-up research and experiment in the field of spur gear system dynamics.
Exposure to high dosage of gold nanoparticles accelerates growth rate in bacteria and yeast by modulating ribosomal protein expression.

Abstract
Gold nanoparticles (AuNPs) have a range of applications in biomedical research yet their effect on cellular and metabolic processes remains poorly understood. We demonstrate that exposure to high-dosages of citrate-stabilized, spherical AuNPs (<10 nm diameter) not only accelerates growth rate of bacteria and yeast. Also, results in a two-fold increase in the number of viable cells by the end of the cell-cycle. Differential proteome analysis reveals that exposure to high doses of AuNPs leads to under-expression of the majority of the ribosomal proteins, except a few, in both E. coli and S. cerevisiae. Interestingly, homologs of over-expressed ribosomal proteins were found to be increased, similar to the cells under stress conditions like cancer. Exclusive sensitivity to sub-lethal dosage of Aminoglycosides and Rapamycin confirms alteration in cellular translation rate. We propose that exposure to high doses of AuNPs creates stress on cellular translational machinery to promote protein synthesis via non-canonical mode.
Partial Descemet’s Membrane Overlap due to Previously Grafted Descemet’s Membrane Remnant: Case Report
Authors: Choi Pureum , Shim Kyu Young , Jun Jong Hwa 
Published: January 2023

Abstract
Background: This study aimed to describe the clinical outcomes of a patient who underwent repeated Descemet’s membrane endothelial keratoplasty (DMEK) on partially remaining Descemet’s membrane (DM) due to firm adhesion.
Case presentation: A 78-year old female experienced vision fluctuations due to corneal edema after DMEK approximately 5 years ago. As scarring of the stroma was minimal, repeated DMEK was planned. The previously grafted DM was firmly attached to the posterior stroma in the inferior half area and could not be completely removed. After the donor lenticule was injected into the anterior chamber and unscrolled, room air was injected and the operation was completed. Two weeks postoperatively, focal detachment was observed at the border of the remnant DM. Focal DM detachment completely resolved without additional procedures 6 weeks postoperatively. At 5 months after surgery, the new DM was well attached, but overlap of the DM was identified on anterior segment OCT and Scheimpflug imaging. In addition, significant posterior astigmatism remained due to the overlap of the DM.
Conclusions: Partially remaining DM disturbed the adhesion of the new DM at the border of the remnant. Despite the extremely thin thickness of lenticule, the overlapped DM induced significant posterior astigmatism.

Published: January 2023

Abstract
Background
We aimed to evaluate the association of sedentary behavior (SB) and moderate to vigorous leisure-time physical activity (MVPA) with sleep quality during the covid-19 pandemic.
Methods
Cross-sectional, population-based study in adults, conducted from October to December 2020 in the Iron Quadrangle region, Brazil. The outcome was sleep quality, evaluated with the Pittsburgh Sleep Quality Index. SB was assessed by self-report of total sitting time, before and during the pandemic. Individuals with ≥ 9 hours of total sitting time were classified as SB. In addition, the ratio of time spent in MVPA to time in SB was analyzed. A contrasted directed acyclic graph (DAG) model was constructed to adjust logistic regression models.
Results
A total of 1629 individuals were evaluated, the prevalence of SB before the pandemic was 11.3% (95%CI: 8.6–14.8) and during the pandemic 15.2% (95%CI: 12.1–18.9). In multivariate analysis, the chance of poor quality sleep was 81% higher in subjects with SB ≥ 9 hours per day (OR: 1.81; 95% CI: 1.10–2.97). Furthermore, a one-hour increase in SB during the pandemic, increased the chance of poor sleep quality by 9% (OR: 1.09; 95%CI 1.01–1.18). In the analysis of the ratio of MVPA per SB in individuals with SB ≥ 9h, practicing 1 minute of MVPA per hour of SB reduces the chance of poor sleep quality by 20.5% (OR: 0.83; 95%CI: 0.70–0.96).
Conclusion
SB during the pandemic was a factor associated with poor sleep quality, and the practice of MVPA can reduce the effects of SB.

Authors: Yoon Yu Jung , Kang Ju Young , Kim Kyung Ho , Cha Jung Yul , Ahn Hyung Joon , Choi Yoon Jeong 
Published: January 2023

Abstract
Objectives: Masticatory function, including masticatory muscle activity and occlusal function, can be affected by craniofacial morphology. This study aimed to investigate the relationship between craniofacial morphology and masticatory function in participants who had completed orthodontic treatment at least two years before and had stable occlusion.
Materials and Methods: Fourty-two healthy participants were prospectively enrolled and divided into three vertical cephalometric groups according to the mandibular plane angle. Masticatory muscle activity (MMA) in the masseter and anterior temporalis muscles was assessed using surface electromyography. The occlusal contact area and occlusal force (OF) were evaluated using the Dental Prescale System. Masticatory muscle efficiency was calculated by dividing MMA by OF. The craniofacial morphology was analyzed using a lateral cephalogram. The masticatory function was compared using one-way analysis of variance. Pearson correlations were used to assess the relationships between craniofacial morphology and masticatory function.
Results: The hypodivergent group had the lowest MMA and the highest efficiencies in the masseter and anterior temporalis muscle (p < 0.05). MMA showed a positive relationship with mandibular plane angle, whereas the occlusal function demonstrated a negative relationship (p < 0.05). The anterior temporalis muscle activity negatively correlated with ramus height (p < 0.05).
Conclusions: Vertical craniofacial morphology was related to masticatory function in participants with normal occlusion after orthodontic treatment. Participants with hypodivergent facial profiles may have low MMA and high occlusal function, resulting in good masticatory muscle efficiency.
Clinical relevance: Vertical craniofacial morphology is an important factor to consider in orthodontic diagnosis and prosthetic treatment planning.

Published: January 2023

Abstract
Background
Cerebral ischemia-reperfusion injury (CIRI) can cause hippocampal inflammation and apoptosis, resulting in anxiety and cognitive dysfunction. Compound porcine cerebroside and ganglioside injections (CPCGI) are used to treat encephalopathy, but its therapeutic effects and mechanism require further exploration.
Methods
We screened key genes associated with the ischemic stroke (IS) and predicted their binding sites with CPCGI. We subsequently injected CPCGI into a middle cerebral artery occlusion (MCAO) rat model. 2,3,5-triphenyl tetrazolium chloride (TTC) staining and behavioral testing were performed. Hippocampal neuronal apoptosis was assessed by immunofluorescence. IL-1β, TNF-α, and NF-κB pathway were detected by Western blotting. Oxygen-glucose deprivation/reoxygenation (OGD/R)-HT-22 cells were treated CPCGI for 72 h. Cell viability and NF-κB were also evaluated.
Results
H2AC20, RPL3, RPL13A, RPL9, RPS23, and RPLP0 were identified as key IS genes. CPCGI was confirmed to interact with these proteins via molecular docking. Functional enrichment reflected the critical role of the NF-κB pathway in CIRI. Infarct volume and behavioral impairments in MCAO rats, especially anxiety and cognitive dysfunction, were improved by CPCGI in a dose-dependent manner. Immunofluorescence confirmed that hippocampal neuronal apoptosis was rescued by the CPCGI. Western blotting revealed that inflammation and NF-κB phosphorylation were inhibited. In vitro experiments showed that CPCGI increased the survival of OGD/R-HT-22 cells and inhibited phosphorylation of the NF-κB signaling pathway.
Conclusion
CPCGI can alleviate anxiety and cognitive dysfunction in CIRI and thus improve psychoneurological symptoms in patients with IS. We confirmed that CPCGI alleviate inflammation and apoptosis in the hippocampus by inhibiting the NF-κB signaling pathway.

Abstract
Intestinal colonization with Klebsiella has been linked to necrotizing enterocolitis (NEC), but methods of analysis usually failed to discriminate Klebsiella species or strains. A novel ~2,500-base amplicon (StrainID) that spans the 16S and 23S rRNA genes was used to generate amplicon sequence variant (ASV) fingerprints for Klebsiella oxytoca and Klebsiella pneumoniae species complexes (KoSC and KpSC, respectively) and co-occurring fecal bacterial strains from 10 preterm infants with NEC and 20 matched controls. Complementary approaches were used to identify cytotoxin-producing isolates of KoSC. Klebsiellaspecies colonized most preterm infants, were more prevalent in NEC subjects versus controls, and replaced Escherichiain NEC subjects. Single KoSC or KpSC ASV fingerprinted strains dominated the gut microbiota, suggesting exclusionary Klebsiella competition for luminal resources. Enterococcus faecaliswas co-dominant with KoSC but present infrequently with KpSC. Cytotoxin-producing KoSC members were identified in most NEC subjects and were less frequent in controls. Few Klebsiellastrains were shared between subjects. We conclude that inter-species Klebsiella competition, within an environment of KoSC and E. faecalis cooperation, appears to be an important factor for the development of NEC. Preterm infants seem to acquire Klebsiella primarily through routes other than patient-to-patient transmission.
