Hydrogen Bonding in Organometallic Crystals. 6. X−H---M Hydrogen Bonds and M---(H−X) Pseudo-Agostic Bonds

Field: Chemistry (Physical Sciences)

The intermolecular interactions between X−H groups (X = C, N, and O) and metal atoms in crystalline organometallic complexes have been investigated. Molecular and crystal structures determined by neutron and/or X-ray diffraction data have been retrieved from the Cambridge Structural Database. The comparative analysis of intermolecular H---M and X---M distances as well as that of the X−H---M angles allows a discrimination between the behavior of electrophilic and nucleophilic metal centers. Two novel types of interactions have been characterized: (i) the intermolecular multicenter hetero-acceptor (IMH) hydrogen bond formed when the X−H donor group interacts with M−X'n systems where M is an electron-rich metal and X' a metal-coordinated electronegative atom (X' = S, N, O, Cl); (ii) the intermolecular pseudo-agostic (IPA) interaction in which the X−H bond can donate electron density to electron deficient metal atoms M---(H-X) as observed in intramolecular agostic interactions. Hydrogen bonding to metal centers in neutral complexes (X−H---M) have been compared with charge assisted (X−H+---M-) hydrogen bonds involving electron-rich anionic complexes.
Perceptions of aging and health behavior: Determinants of a healthy diet in an older german population

Field: Social Sciences (Social Sciences)

The objectives of this study were to assess the association between perceptions of aging and health behavior, and to identify determinants of a healthy diet. Self-reported data obtained by computer-assisted telephone interviews from 2,002 German participants were analyzed. General population. 982 randomly selected men and 1,020 women aged 50–70 years were surveyed. The questionnaire consisted of 31 items concerning attitudes on age and aging (5-point Likert scale). Additionally variables including dietary habits, exercise, smoking, alcohol consumption as well as sociodemographic variables were also assessed. Factor and cluster analyses were used to identify typical perceptions of aging. Determinants of a healthy diet were identified by regression analysis. Three different perceptions were found: "fit and performance-hungry" (n=808), "conventional" (n=618), and "easygoing and committed" (n=576). The "fit and performance-hungry" engaged in exercising more regularly and were more likely to follow a healthy diet compared to the other groups in the sample. Diet was associated with attitudes and beliefs and came along with other favorable health behaviors like regular exercising and nonsmoking. Individuals with a positive perception of aging showed a significantly better health behavior than those who identified themselves with a conventional perception of aging. Individual perceptions of aging are an important starting point when designing prevention programs for older adults.
Habitat fragmentation and ecological traits influence the prevalence of avian blood parasites in a tropical rainforest landscape. PLoS ONE

Field: Agricultural and Biological Sciences (Life Sciences)

In the tropical rainforests of northern Australia, we investigated the effects of habitat fragmentation and ecological parameters on the prevalence of blood-borne parasites (Plasmodium and Haemoproteus) in bird communities. Using mist-nets on forest edges and interiors, we sampled bird communities across six study sites: 3 large fragments (20–85 ha) and 3 continuous-forest sites. From 335 mist-net captures, we recorded 28 bird species and screened 299 bird samples with PCR to amplify and detect target DNA. Of the 28 bird species sampled, 19 were infected with Plasmodium and/or Haemoproteus and 9 species were without infection. Over one third of screened birds (99 individuals) were positive for Haemoproteus and/ or Plasmodium. In forest fragments, bird capture rates were significantly higher than in continuous forests, but bird species richness did not differ. Unexpectedly, we found that the prevalence of the dominant haemosporidian infection, Haemoproteus, was significantly higher in continuous forest than in habitat fragments. Further, we found that ecological traits such as diet, foraging height, habitat specialisation and distributional ranges were significantly associated with blood-borne infections.
Valorisation of agricultural by-product: Optimisation of alcohol-based extraction of polyphenols from chestnut peel using Box-Behnken Design

Field: Agricultural and Biological Sciences (Life Sciences)

In the present work, solvent concentration, extraction time, and solid to solvent (S/S) ratio were evaluated in order to recover the majority of polyphenols from chestnut peel waste using ethanol and methanol. Extraction method for polyphenols from peel pre-treated by ohmic heating (OH) was optimised using response surface methodology (RSM). The effect of these independent variables on total phenolic content (TPC) and antioxidant capacity (AC) was studied using Box-Behnken Design (BBD). A second-order polynomial model provided a satisfactory fit to the experimental data with a high coefficient of determination (R2) value. Results showed that S/S ratio and solvent concentration were generally significant variables during extraction in terms of TPC and AC. The optimum extraction conditions were obtained as 1/10 of S/S ratio and 60% of solvent concentration for both solvents. As the optimum extraction time, 82.41 min for ethanolic extraction and 116.97 min for methanolic extraction were selected. Under these optimal conditions, TPC values of the ethanolic and methanolic extracts were found to be 39.02 and 38.79 mg gallic acid equivalents per gram of dry matter (mg GAE/g DM), respectively, thus indicating highly close agreement to the predicted values. Consequently, the effectiveness of the solvents used was found to be very similar to each other. The OH pre-treatment appeared to be a promising technique for polyphenolic extraction from industrial wastes.
Quantitative analysis of pulmonary ventilation scans with N-13 nitrogen gas and positron computed tomography

Field: Medicine (Health Sciences)

The authors developed a quantitative method for the analysis of pulmonary ventilation studies using N-13 labeled nitrogen gas and positron computed tomography (PCT). The subject inhales N-13 nitrogen gas diluted with oxygen gas in a closed circuit. When the count rate comes up to the equilibrium in 2 or 4 minutes, the equilibrium phase scan (EQ) is performed for 3 min. Then the radioactive gas is washed out by the room air, during which the washout phase scan (WO) is performed for 5 min. Because nitrogen gas is almost insoluble in blood or tissue, the activity of the alveolus can be described with single compartment model if the dead space is ignored. The authors integrated the equation during the scanning period of EQ or WO, expressed the pixel count in each scan with V and T, and solved the equations simultaneously to obtain V and T. In clinical studies, poorly ventilated regions, which had decreased counts in EQ images, showed normal value in V images. Fibrotic regions showed normal T and decreased V. The authors method yields not only the distribution of alveolar volume which they cannot evaluate in EQ images, but also more accurate regional T values than Stewart-Hamiltonmore » method. Thus it is useful for the evaluation of regional pulmonary ventilatory function.« less
EP1037 Predictive accuracy of the risk of malignancy index and clinicopathological results of patients with probably malignant pure adnexal mass (without acidity and implantation)

Field: Medicine (Health Sciences)

Introduction/Background

Adnexal mass is one of the leading causes of admission to the gynecology clinics. Distinction and early diagnosis of malignancy are critical points that the surgical procedure (laparotomy/ laparoscopy, incision type, debulking) and experience/ competence of the surgeon play a major role in the prognosis of the patient who has malignancy. Some of existing indexes are too complex to be used in daily practice, and some contain markers that cannot be done anywhere.Risk of malignancy index(RMI) is practical and simple.

Methodology

Between January 2010 and December 2018, 264 patients who had purely adnexal mass and underwent surgery due to presumed malignancy were analyzed. Since 56 patients had data loss, 208 patients were included in the study. RMI-3 and RMI-4 scores were calculated retrospectively.

Results

According to the final pathology reports, 52 (25%) of 208 patients were benign, 46 (22%) were borderline and 110 (53%) were malignant. Age and menopausal status were significantly different only in borderline group (table 1). Of malignant tumors, 3 were uterine sarcomas, 8 were metastatic ovarian tumors (all gastrointestinal origin), 99 were primary ovarian cancers. 76 of primary ovarian cancers were epithelial and 23 were nonepithelial. The most common type were respectively serous and endometrioid adenocarcinoma. 76% of primary ovarian cancers were at early stage (stage1–2) and 24% were at advanced stage (stage 3–4). RMI-3 and RMI-4 were both have low specificity, sensitivity and predictive values (table 2). The most unexpected benign tumors were serous cystadenofibroma(%24).

Conclusion

For patients with adnexal masses who are not easily accessible to gynecological oncologists, the ability to differentiate benign/ malignant in less specialized hospitals by simple methods will prevent unnecessary referrals and inadequate surgical procedures. This index and our approach are not sufficient.New techniques need to be developed.

Persistent sinus tract formation 1 year following cast post-and-core replacements: a case report.

Field: Dentistry (Health Sciences)

Sinus tracts are paths of drainage for abscesses and can occur both intraorally and extraorally. It is a fact that sinus tracts can heal with proper endodontic therapy. However, there are those types that are persistent and will not respond to any treatment. In these perplexing cases, it may be necessary to elevate a surgical flap to unveil the real etiologic factor. In this article, a case is presented in which 2 persistent and nonhealing sinus tracts were observed around the maxillary left incisor area of a 53-year-old female patient. A difficult cast post-and-core removal had been accomplished to the compromised tooth 1 year previously. A surgical flap had to be reflected, and the cause of the persistent inflammation was determined to be 2 separate root perforations. The granulation tissue was removed, the perforations were sealed with mineral trioxide aggregate, and bone graft was packed in the resorptive bone areas. The symptoms subsided by the time of the 2-week recall. No complaints were noted from the patient during the 4-month follow-up period. This case is a good example that demonstrates the possible complications of post preparation and the necessity of explorative surgery for unveiling the etiologic factor of persistent sinus tract formation.
Let’s collaborate: exploring Library and Information Science lecturers’ and students’ experience of social media as a collaboration tool through phenomenography

Field: Social Sciences (Social Sciences)

This research aims to explore variations in the ways Library and Information Science (LIS) lecturers and students experience social media as a collaboration tool at one Indonesian university. The method for this research is phenomenography because this research aims to explore variations of experience. The social media platform that we investigated is a Facebook group. The research data was collected from interviews with seven participants who were either a lecturer or a student at the university and also the member of the Facebook group that was investigated. The findings of this research are presented in two sets: lecturers’ experience and students’ experience. In the lecturers’ experience of the Facebook group, six categories were revealed: Substituting learning management system; Sharing information; Staying connected; Streamlining lecturers’ teamwork; Lacking students’ participation; and Finding uninformed students. In the students’ experience of the Facebook group, six categories were revealed: Staying informed; Sharing information; Staying connected; Substituting learning management system; Feeling unsatisfied with the platform features; and Being passive members. The findings of this research provide insights into variations in the ways Indonesian LIS teaching staff and students experience the Facebook group as a collaboration tool. As the first empirical research explores this phenomenon, this research provides a research base of social media practice to support teaching and learning in LIS education setting in Indonesia. The research findings also have several important practical implications including informing other LIS schools in Indonesia on the social media practice as a collaboration tool in LIS education setting.
Efficient Palladium‐Assisted One‐Pot Deprotection of (Acetamidomethyl)Cysteine Following Native Chemical Ligation and/or Desulfurization To Expedite Chemical Protein Synthesis

Field: Chemistry (Physical Sciences)

Abstract The acetamidomethyl (Acm) moiety is a widely used cysteine protecting group for the chemical synthesis and semisynthesis of peptide and proteins. However, its removal is not straightforward and requires harsh reaction conditions and additional purification steps before and after the removal step, which extends the synthetic process and reduces the overall yield. To overcome these shortcomings, a method for rapid and efficient Acm removal using Pd II complexes in aqueous medium is reported. We show, for the first time, the assembly of three peptide fragments in a one‐pot fashion by native chemical ligation where the Acm moiety was used to protect the N‐terminal Cys of the middle fragment. Importantly, an efficient synthesis of the ubiquitin‐like protein UBL‐5, which contains two native Cys residues, was accomplished through the one‐pot operation of three key steps, namely ligation, desulfurization, and Acm deprotection, highlighting the great utility of the new approach in protein synthesis.
Cost-effective Detection Model for Injected Automatic Dependent Surveillance-Broadcast Messages (ADS-B) for Secure Aviation Control

Field: Computer Science (Physical Sciences)

Abstract

Automatic Dependent Surveillance-Broadcast (ADS-B) is considered the future of aviation surveillance and traffic control as it allows different types of aircraft to transmit and gain information about their and other nearby aircraft's positions, velocity, and various other variables periodically. But, as this protocol still show that it lacks in terms of security and that researchers are still developing more methods and frameworks in order to secure this technology, we decided to join the initiative and propose an efficient detection method to help aid with detecting any attempts at injecting these messages which would cause multiple risks to aircrafts such as causing collision avoidance system failure, reporting wrong status of an aircraft, or even stealing it. This paper focused mainly on three different attacks; path modification, ghost aircraft injection, and velocity drift attacks. The dataset we utilized consisted of authentic messages captured from the OpenSky Network and generated injected messages using PyCharm. This study aims to provide a revolutionary methodology that, even in the face of new attacks (zero-day attacks), can successfully detect injected messages. The main advantage was utilizing a recent dataset to create more reliable and adaptive training and testing materials, which were then preprocessed before using different machine learning algorithms to feasibly create the most accurate and time-efficient model. The best outcomes of the binary classification were obtained with 99.14% accuracy, an F1-Score of 99.14%, and a Matthews' Correlation Coefficient (MCC) of 0.982. At the same time, the best outcomes of the multiclass classification were obtained with 99.41% accuracy, an F1-Score of 99.37%, and a Matthews' Correlation Coefficient (MCC) of 0.988. The dataset is thought to offer good outcomes, but the model still requires more testing and a bigger dataset, bearing in mind that the model still needs to be tested against other types of attacks.

Glomerella acutata on Highbush Blueberry (Vaccinium corymbosum L.) in Norway

Field: Agricultural and Biological Sciences (Life Sciences)

In August 2004, Glomerella acutata Guerber & Correll was detected on fruits from highbush blueberry (Vaccinium corymbosum L.) for the first time in Norway. Both the conidial (Colletotrichum acutatum J. H. Simmonds) and the ascigerous (G. acutata) stage developed on naturally infected blueberry fruits. Perithecia also readily formed on blueberries and strawberries inoculated with a culture from highbush blueberry, and on artificial, solid medium (both on strawberry leaf agar and potato dextrose agar). To our knowledge this is the first report worldwide of the teleomorph of Glomerella acutata on a naturally infected host. Accepted for publication 15 January 2007. Published 9 May 2007.
Structure Prompt Augmented Language Model Embedding on Electrical Equipment Defect Knowledge Graph

Field: Computer Science (Physical Sciences)

Knowledge graphs have demonstrated significant impact in the power grid domain, facilitating various applications such as defect diagnosis and grid management. However, their reasoning capabilities have not been fully exploited. In this paper, we explore the utilization of knowledge graphs for power grid defect diagnosis. We construct an electrical equipment defect knowledge graph and predict missing links, which is also known as Knowledge Graph Completion (KGC). However, we notice the long-tail problem in electrical equipment knowledge graph. To tackle this challenge, we propose a novel text-based model named SPALME (Structure Prompt Augmented Language Model Embedding) that incorporates structural information as prompts. Our model leverages the power of pre-trained language models, allowing it to comprehend the semantic information of entities and relationships in the knowledge graph. Additionally, by integrating structural information as prompts during the learning process, our model gains a deeper understanding of the graph’s topological structure efficiently, effectively capturing intricate dependencies between grid equipments. We evaluate our approach on various datasets. The results demonstrate that our model consistently outperforms baseline methods on the majority of the datasets.
A new record of the Lessepsian fish Etrumeus golanii (Teleostei: Clupeidae) in the Gulf of Gabes, Tunisia, with notes on its parasites

Field: Agricultural and Biological Sciences (Life Sciences)

The presence of the Lessepsian migrant red-eye round herring Etrumeus golanii (Clupeidae) is confirmed in Tunisian coastal waters with the record of 7 specimens captured in June 2014 in the Gulf of Gabes. Total length of E. golanii individus captured on the Tunisian coast is comprised between 22.5 and 26.5 cm. All specimens are mature females with gonads weighing between 3.97 and 5.25 g. Morphometric and meristic characteristics of the species are described with notes on its parasites. Different developmental stages of 3 parasites Lecithochirium jaffense (Digenea), Anisakis sp. (Nematoda) and Gnathia sp. (Isopoda) were collected. This new record of E. golanii may confirm the rapid range expansion of this Lessepsian migrant in the Central Mediterranean Sea, as well as the infection with parasites newly reported in this host.
