New Variants of Nitroxide Mediated Polymerization

Nitroxide-mediated polymerization is now a mature technique, at 35 years of age. During this time, several variants have been developed: enhanced spin capture polymerization (ESCP), photoNMP (NMP2), chemically initiated NMP (CI-NMP), spin label NMP (SL-NMP), and plasmon-initiated NMP (PI-NMP). This mini-review is devoted to the features and applications of these variants.
A Hybrid Model for Predicting Bone Healing around Dental Implants

Background: The effect of the short-term bone healing process is typically neglected in numerical models of bone remodeling for dental implants. In this study, a hybrid two-step algorithm was proposed to enable a more accurate prediction for the performance of dental implants. Methods: A mechano-regulation algorithm was firstly used to simulate the tissue differentiation around a dental implant during the short-term bone healing. Then, the result was used as the initial state of the bone remodeling model to simulate the long-term healing of the bones. The algorithm was implemented by a 3D finite element model. Results: The current hybrid model reproduced several features which were discovered in the experiments, such as stress shielding effect, high strength bone connective tissue bands, and marginal bone loss. A reasonable location of bone resorptions and the stability of the dental implant is predicted, compared with those predicted by the conventional bone remodeling model. Conclusions: The hybrid model developed here predicted bone healing processes around dental implants more accurately. It can be used to study bone healing before implantation surgery and assist in the customization of dental implants.
Identifying gaps across the cascade of care for the prevention of HBV mother‐to‐child transmission in Burkina Faso: Findings from the real world

Prevention of mother‐to‐child transmission (PMTCT) is a challenge for controlling the hepatitis B epidemic. In Sub‐Saharan countries, pilot interventions including the screening of pregnant women for HBsAg, implementation of anti‐HBV therapy and infant immunization within 24 hours of life are initiated and need to be evaluated. This pilot study aimed to describe the cascade of care for hepatitis B PMTCT in a real life situation, and to identify sociodemographic factors associated with adequate management of pregnant women and infants.
Middle East Respiratory Syndrome Coronavirus (MERS-CoV): State of the Science

Coronaviruses belong to a large family of viruses that can cause disease outbreaks ranging from the common cold to acute respiratory syndrome. Since 2003, three zoonotic members of this family evolved to cross species barriers infecting humans and resulting in relatively high case fatality rates (CFR). Compared to Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV, CFR = 10%) and pandemic Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2, CFR = 6%), the Middle East Respiratory Syndrome Coronavirus (MERS-CoV) has scored the highest CFR (approximately 35%). In this review, we systematically summarize the current state of scientific knowledge about MERS-CoV, including virology and origin, epidemiology, zoonotic mode of transmission, and potential therapeutic or prophylactic intervention modalities.

Soluble Carbohydrates in Two Buffalograss Cultivars with Contrasting Freezing Tolerance

No information is available regarding endogenous soluble carbohydrate accumulation in buffalograss (Buchloe dactyloides (Nutt.) Engelm. ) during cold acclimation. The objective of this study was to determine composition of soluble carbohydrates and their relationship to freezing tolerance in two buffalograss cultivars, 609 and NE 91-118, with different freezing tolerances. The experiment was conducted under natural cold acclimation conditions in two consecutive years in Fort Collins, Colo. Based upon average LT 50 (subfreezing temperature resulting in 50% mortality) from seven sampling intervals in 1998-99 and six sampling intervals in 1999-2000, 'NE 91-118' survived 4.5 °C and 4.9 °C colder temperatures than '609', during the 1998-1999 and 1999-2000 winter seasons, respectively. Glucose, fructose, sucrose, and raffinose were found in both cultivars in both years, and were generally higher in acclimated than pre- and post-acclimated stolons. Stachyose was not present in sufficient quantities for quantification. Cultivar NE 91-118 contained 63% to 77% more glucose and 41% to 51% more raffinose than '609' in the 1998-99 and 1999-2000 winter seasons, respectively. In 1999-2000, fructose content in 'NE 91-118' was significantly higher than that of '609'. A significant negative correlation was found between LT 50 vs. all carbohydrates in 1999-2000, and LT50 vs. sucrose and raffinose in 1998-99. Results suggest that soluble carbohydrates are important in freezing tolerance of buffalograss.
Frame graph

Abstract Let be a finite-dimensional Hilbert space and be a finite frame for . For , we associate a simple graph denoted by and called frame graph, with all elements of as vertices, and two distinct vertices are adjacent when the inner product of them is nonzero. The associated graph is called a tight frame graph if the mentioned frame is tight. In this paper, we study some basic properties of and investigate the relation between the frame-theoretic properties of and the graph-theoretic properties of . For example, it is shown that trees on more than two vertices and cycles on more than five vertices are not tight frame graphs while complete graphs, complete graphs minus a single edge and the join of each graph with itself are tight frame graphs.
Population dynamics and epibiont associations of hermit crabs (Crustacea: Decapoda: Paguroidea on Dog Island, Florida

Sandford, F. 2003. Population dynamics and epibiont associations of hermit crabs (Crustacea: Decapoda: Paguroidea) on Dog Island, Florida. In: Lemaitre, R. , and Tudge, C.C. (eds), Biology of the Anomura. Proceedings of a symposium at the Fifth International Crustacean Congress, Melbourne, Australia, 9‐13 July 2001. Memoirs of Museum Victoria 60(1): 45‐52. Periodic belt transects and daily shoreline surveys in January and in June‐July over a 10-year period (1992‐2001) were used to study the seven species of hermit crabs most common in the upper intertidal zone of a low energy bay with a 960 m shoreline at the east end of Dog Island, Florida, and their association with three common shell epibionts in the area: the Florida hermit-crab sponge, Pseudospongosorites suberitoides, the cloak anemone, Calliactis tricolor, and the hydrozoan Hydractinia echinata. Of 15,052 hermit crabs sampled, Pagurus longicarpus, Pagurus pollicaris, and Pagurus impressus were prevalent in January (88% of all animals) and Clibanarius vittatus dominated in the summer (86% of all animals). The following associations were highly significant: P. impressus with P. suberitoides, P. pollicaris with H. echinata, and Petrochirus diogenes with C. tricolor. C. vittatus rarely had anemones, and P. impressus were never found in shells with H. echinata and showed a significant tendency, whether in sponge or shell shelters, to become stranded compared to other pagurid species. Hermit crab sponges were commonly used as shelters by only two of the hermit crab species, P. impressus and Paguristes hummi. Together these two species accounted for 99% of the 1077 animals found in sponges. Hermit crab sponges varied yearly in abundance from plentiful to uncommon, and nearly half (1030 of 2107, or 49%) were empty.
No-Reference Quality Assessment of Super-Resolution Reconstructed Images by Incorporating Domain Knowledge

Super resolution (SR) has been extensively studied these years due to its wide applications in machine vision, medical imaging and remote sensing, etc. With a great number of SR image reconstruction algorithms proposed, an accompanying task is how to evaluate the quality of SR reconstructed images. Although a number of image quality metrics have been reported, they are not speciﬁcally designed for image super resolution, so the are usually limited for this task. Motivated by these, this paper presents a no-reference quality metric for SR reconstructed images by measuring structure degradations and SR-relevant domain distortions. By incorporating domain knowledge, the proposed metric is more eﬀective than the state-of-the-art models for the quality assessment of SR reconstructed images. Experimental results based on three subjectively-rated SR image databases demonstrate the advantages of the proposed metric in terms of both prediction performance and generalization ability.
Serum IgM against SARS-CoV-2 correlates with in-hospital mortality in severe/critical patients with COVID-19 in Wuhan, China

Severe/critical patients with coronavirus disease 2019 (COVID-19) have become the central issue in the current global pandemic due to their high mortality rate. However, the relationship between antibody response and clinical outcomes has not been well described in this group. We conducted a single-center, retrospective, cohort study to investigate the relationship between serum immunoglobulin G (IgG) and IgM and clinical outcomes in severe/critical patients with COVID-19. Seventy-nine severe/critical patients with COVID-19 admitted in Wuhan Asia General Hospital in Wuhan, China during January 22, 2020 to March 6, 2020 were included. Serum antibodies were measured at day 25 (SD, 7) post illness onset. The median IgG titer was 113 (IQR 81-167) AU/ml, and IgM titer was 50 (IQR, 23-105) AU/ml. Patients whose IgM titer ≥ 50 AU/ml had higher in-hospital mortality (p=0.026). IgM titer ≥ 50 AU/ml was also correlated with higher incidences of Acute Respiratory Distress Syndrome (ARDS) and sepsis shock. Antibody remeasurements were performed in 42 patients, where IgM titer declined significantly in survivors (p=0.031). Serum IgM titer changes according to the COVID-19 progression. The severe/critical patients with COVID-19 have a higher risk of clinical adverse events when IgM titer ≥ 50 AU/ml. Further decreasing of IgM could imply a better outcome in severe/critical cases.
Bioinformatics Analysis of Evolution and Human Disease Related Transposable Element-Derived microRNAs

Transposable element (TE) has the ability to insert into certain parts of the genome, and due to this event, it is possible for TEs to generate new factors and one of these factors are microRNAs (miRNA). miRNAs are non-coding RNAs made up of 19 to 24 nucleotides and numerous miRNAs are derived from TE. In this study, to support general knowledge on TE and miRNAs derived from TE, several bioinformatics tools and databases were used to analyze miRNAs derived from TE in two aspects: evolution and human disease. The distribution of TEs in diverse species presents that almost half of the genome is covered with TE in mammalians and less than a half in other vertebrates and invertebrates. Based on selected evolution-related miRNAs studies, a total of 51 miRNAs derived from TE were found and analyzed. For the human disease-related miRNAs, total of 34 miRNAs derived from TE were organized from the previous studies. In summary, abundant miRNAs derived from TE are found, however, the function of miRNAs derived from TE is not informed either. Therefore, this study provides theoretical understanding of miRNAs derived from TE by using various bioinformatics tools.
Why is cannibalism less frequent when larvae of sutchi catfish Pangasianodon hypophthalmus are reared under dim light

Survival rates of the larvae of sutchi catfish Pangasianodon hypophthalmus are reported to be three times higher under dim conditions (0.1 lx) than those under 100 lx. In this study, larval behaviour of sutchi catfish was examined under various light intensities (<0.01, 0.1, 1, 10 and 100 lx) using a CCD camera to understand why survival rates vary under different light intensities. Five-day-old larvae showed significantly higher swimming activity under <0.01, 0.1 and 1 lx than those under 10 and 100 lx. On the other hand, the larvae showed significantly higher aggressive behaviour under 10 and 100 lx; swimming larvae attacked resting individuals more frequently under 10 and 100 lx than those under 0 and 0.1 lx. Aggressive behaviour was considered to induce lesions, inflicted by the sharp teeth of attacking larvae, on larval skin surfaces. It is considered that the chemical substances would generate from injured skin surfaces then acted as stimuli, causing the cannibalistic behaviour in other fish around the injured fish. This study provided evidence that the observed higher survival rates depended on lower frequency of aggressive behaviour under dark or dim conditions. It is therefore recommended that larval rearing of sutchi catfish be conducted under dim (less than 1 lx) conditions. Â© 2013 John Wiley & Sons Ltd.
BIOCHEMICAL COMPOSITION OF MANGROVE CARB SESARMA BROCKII FROM PONDICHERRY SOUTHEAST OF INDIA

Finfish, shellfish and other aquatic organisms suitable for food and feed are of worldwide importance. They are excellent sources of high quality proteins and biochemical composition.The present study deals with biochemical composition of common mangrove crab Sesarma brockii. The proximate composition of protein, carbohydrate, lipid, moisture, ash, amino acids, fatty acids, vitamins and minerals were studied. The results of proximate composition in S. brockii showed the percentage of protein was high 26.1%, followed by the carbohydrate 10.43%, lipid 3.24% moisture 43.69% and ash 16.54%. The total essential amino acids were found to be as 60.03 % and non-essential amino acids were 39.55 %. Among the essential amino acids Methionine were found high as 16.8 % on dry matter basis in crab tissue. The nonessential amino acids Glutamic acid were found maximum as13.4 % on dry matter basis in crab tissue. In the analysis, the fatty acid profile by gas chromatography revealed the presence of higher amount of SFA (Stearic acid 26.3 %) and PUFA (Stearidonic acid 19.8 %). The details of the vitamins detected in S. brockiitissue. Among them, vitamin A and C were found in higher levels (19.64 & 15.67 mg/g). In the present study, totally 5 macro minerals and 2 trace minerals were reported. The S. brockii body tissue contributed maximum calcium (209.3 mg/g) potassium (115.3 mg/g) of minerals. The result shows that mangrove crab (S. brockii) tissue is a valuable food recipe for human consumption, due to its high quality protein and well-balanced amino acids fatty acids.
Interpersonal Violence and Psychotic-Like Experiences: The Mediation of Ideas of Reference, Childhood Memories, and Dissociation

Previous studies have demonstrated the relationship between the accumulation of situations involving interpersonal violence (IV) and psychotic-like experiences. This study explored whether IV is related to aberrant salience (AS), using a sequential mediation model that included memories of relationship with parents (submission, devaluation, and threat; Early Life Experiences Scale (ELES)), ideas of reference (IR), and dissociative symptoms (absorption and depersonalization), and whether the patient/nonpatient condition moderated this effect. The sample was made of 401 participants (including 43 patients with psychotic disorders) aged 18 to 71 years (Mage = 30.43; SD = 11.19). Analysis of a serial multiple mediator model revealed that IR, ELES, absorption, and depersonalization fully mediated the effect of IV on AS, explaining 39% of the variance, regardless of the patient/nonpatient condition. The indirect paths, which place IR and dissociation (especially absorption, the variable to which the IR and ELES lead) in a primordial position for being related to AS, are discussed. This continuum model could be useful for understanding processes related to the onset of psychosis unmoderated by the patient/nonpatient condition.
Impacts of the COVID‐19 pandemic on Iranian patients with epilepsy

To investigate the effects of COVID‐19 pandemic on patients' perceptions of hardship in obtaining their drugs and if this pandemic and the social restrictions in response to that has resulted in any changes in their seizure control status. We also investigated factors potentially associated with the perceptions of difficulty in obtaining their drugs (eg, polytherapy vs monotherapy, taking imported drugs, and seizure status worsening).
Discovering the Relationships Between Perceived Emotional Value, City and Friend Attachment, School ID, WOM and Educational Satisfaction: A Structural Research for University Students

Rapid transformations in higher education in recent years have made deeper researches about student-university relationship mandatory. Regarding the subject, Anderson, Sullivan, and Swidler (1993) stated that students who are the consumers of universities will have very important benefits for higher education institutions in determining the factors related to education satisfaction. So, the aim of this research is designed to determine the relationships between university students’ satisfaction with education, the emotional value they perceive, school identity, city attachment and positive WOM behavior. For the relevant purpose, 366 university students were reached online. The empirical data obtained were analyzed with a two-step approach (measurement and structural) in line with the basic methodological principles of SEM. Acceptance of all hypotheses created within the scope of the structural model proved empirical relationships between the related structures. The research has provided new perspectives to the ongoing discussions in the related literature by proving the direct or indirect effects of structures such as city attachment, emotional value, and school identity on university satisfaction. The results provided tips for professionals in the field to create educational satisfaction.
ENZYMATIC ACTIVITY OF FRESH WATER ACTINOMYCETES

Fresh water systems represent a largely untapped source for isolation of novel microorganisms. Gram - positive actinomycetes are of special interest, since they are known to produce chemically diverse compounds with wide range of biological activities. Twenty four actinomycetes with distinct characteristics were isolated from three freshwater systems of Karimnagar, Andhra Pradesh, India viz: Lower Manai r Dam, Manakondur Pond and Kothapally Pond. These isolates were screened for their antagonistic activity. Among, eight showed antagonistic activity against test bacteria. Enzymatic activity of these antibacterial actinomycete isolates was performed which r evealed that, out of eight actinomycetes, 8(100%), 7(87%), 6(75%), 6(75%), 8(100%), were possessing amylase, protease, urease, cellulase and lipase activity respectively. It was found that all tested active isolates were lacking chitinase activity. It was thus seen from above results that high numbers of actinomycetes were biochemically active in fresh water systems and play significant role i n decomposition of complex organic matter.
Phylogenetic Relationships of the Genera of North American Sunfishes and Basses (Percoidei: Centrarchidae) as Evidenced by the Mitochondrial Cytochrome b Gene

Abstract The phylogenetic relationships of genera of the family Centrarchidae and its affinities to the Elassomatidae were examined using the mitochondrial DNA sequences of the cytochrome b gene. A total of 32 individuals representing 16 species from nine genera of centrarchids were sequenced. Outgroup were drawn from other perciform families including several families previously proposed to be closely related to the Centrarchidae. Phylogenetic analysis was conducted using the optimality criteria of maximum parsimony with two weighting schemes and using the maximum likelihood method. A priori and a posteriori alternative hypotheses of relationships within the Centrarchidae were investigated using the Shimodaira and Hasegawa Test. The results of all analyses support the monophyly of the Centrarchidae, although the interrelationships of centrarchid genera differed between analyses. Elassoma was never recovered as the sister taxon to the Centrarchidae; however, the sister relationship of these taxa could not be rejected. Additional data are required to unambiguously resolve relationships among centrarchid genera and determine the relationship of the Centrarchidae to other perciforms.
