Morpho-anatomical and micromorphometrical evaluations in soybean genotypes during water stress

In a greenhouse experiment, morpho-anatomical and micromorphometrical analyses of two soybean cultivars, MG/BR46 (Conquista) and BR16-tolerant and sensitive to drought, respectively-were used to study their water-deficit-tolerance strategies. Drought treatments were applied at reproductive stages from R2 to R7, where evaluations were conducted at 30 days and 45 days after stress started, respectively. The total length of Conquista plants (shoot + root) was greater than of BR16 plants. Pod dry weight was adversely affected due to the lack of moisture, decreasing productivity even of Conquista plants. Both the cultivars had normal development of root hairs; however, it was observed a decrease in the cortex:central cylinder ratio in BR16 stressed for 30 days, and they also showed similar leaflet thickness and stomata distribution. Differences in drought tolerance observed between the two cultivars seemed to be related to factors other than morphological traits since this species has a short lifecycle.
Zinc Ion-induced Domain Organization in Metallo-β-lactamases

The reversible unfolding of metallo-β-lactamase from Chryseobacterium meningosepticum (BlaB) by guanidinium hydrochloride is best described by a three-state model including folded, intermediate, and unfolded states. The transformation of the folded apoenzyme into the intermediate state requires only very low denaturant concentrations, in contrast to the Zn2-enzyme. Similarly, circular dichroism spectra of both BlaB and metallo-β-lactamase from Bacillus cereus 569/H/9 (BcII) display distinct differences between metal-free and Zn2-enzymes, indicating that the zinc ions affect the folding of the proteins, giving a larger α-helix content. To identify the regions of the protein involved in this zinc ion-induced change, a hydrogen deuterium exchange study with matrix-assisted laser desorption ionization tandem time of flight mass spectrometry on metal-free and Zn1- and Zn2-BcII was carried out. The region spanning the metal binding metallo-β-lactamases (MBL) superfamily consensus sequence His-X-His-X-Asp motif and the loop connecting the N- and C-terminal domains of the protein undergoes a zinc ion-dependent structural change between intrinsically disordered and ordered states. The inherent flexibility even appears to allow for the formation of metal ion-bridged protein-protein complexes which may account for both electrospray ionization-mass spectroscopy results obtained upon variation of the zinc/protein ratio and stoichiometry-dependent variations of 199mHg-perturbed angular correlation of γ-rays spectroscopic data. We suggest that this flexible “zinc arm” motif, present in all the MBL subclasses, is disordered in metal-free MBLs and may be involved in metal ion acquisition from zinc-carrying molecules different from MBL in an “activation on demand” regulation of enzyme activity.
Effects of Manual Therapy on Fatigue, Pain, and Psychological Aspects in Women with Fibromyalgia

Fibromyalgia is a condition characterised by chronic widespread muscle pain and fatigue, sleep disturbances, cognitive disorders, and mood disturbance. The purpose of this study was to determine the effectiveness of a manual therapy technique performed with moderate digital pressure in women with fibromyalgia (n = 24). In this randomised, controlled trial, the participants were randomly assigned to the experimental group or placebo group. The experimental group was assisted with manual therapy sessions based on connective tissue massage, whereas the placebo group was “treated” with ultrasound sessions performed without conductive gel and with the machine turned off as the placebo. Fatigue severity scale (FSS), visual analogical scale (VAS), Pittsburgh sleep quality index (PSQI), and profile of mood states (POMS-29) were completed before and after the intervention. In the experimental group (manual therapy), significant results were obtained on a VAS scale, referring to the neck pain in patients with fibromyalgia (p < 0.001). Correlations showed a relationship between fatigue and sleep variables (R = 0.411; p = 0.046) and pain variables with the POMS anger-hostility subscale (R = 0.436; p = 0.033). Although the size of the sample could be a limitation, the study concluded that the application of manual therapy in fibromyalgia patients performed with moderate pressure for 15 min on the posterior cervical musculature decreased the perception of pain, muscle fatigue, and the state of tension-anxiety.
Low rate of point mutation in the mtDNA noncoding fragment of Hypericum taxa

Background and Purpose: Contrary to a major impact of phylogenetic studies on humans and animals, application of the mitochondrial DNA (mtDNA) analysis in plant phylogeny research is rather sporadic due to its high rate of rearrangments and low rate of point mutations. Nevertheless, mtDNA analysis gave interesting results in some taxa. With the aim to test variability and applicability of the mtDNA in the phylogenetic investigation of genus Hypericum, four noncoding regions of mtDNA were compared using the mtDNA RFLP on thirty-six Hypericum taxa. Materials and Methods: Total cellular DNA was extracted from fresh or frozen leaves of thirty-six Hypericum taxa native in different part of the world. The PCR-amplified products of four noncoding mtDNA regions (ccb, cox3, nad1, nad4) were digested with six restriction endonucleases. Results and Conclusions: Out of thirty-six Hypericum taxa belonging to fifteen sections and 14 restriction profiles, differences were observed in only two species profile. One deletion was found in the nad1/Hinf I restriction profile of H. pseudohenryi, while gain of restriction site was detected in the nad1/RsaI restriction profile of H. hirsutum. Obtained results confirmed slow sequence evolution of the Hypericum mtDNA, for plant mtDNA in general.

KU-CST at the SIGMORPHON 2020 Task 2 on Unsupervised Morphological Paradigm Completion

We present a model for the unsupervised dis- covery of morphological paradigms. The goal of this model is to induce morphological paradigms from the bible (raw text) and a list of lemmas. We have created a model that splits each lemma in a stem and a suffix, and then we try to create a plausible suffix list by con- sidering lemma pairs. Our model was not able to outperform the official baseline, and there is still room for improvement, but we believe that the ideas presented here are worth considering.
Influence of Self-Efficacy and Motivation to Follow a Healthy Diet on Life Satisfaction of Patients with Cardiovascular Disease: A Longitudinal Study

Today, cardiovascular disease has a great impact on the global population due to its high prevalence. One challenge that cardiovascular patients face to achieve a better prognosis is to follow a healthy diet. This study focused on psychological factors linked to adaptation to a healthy diet in these patients. The main objective was to analyze the interrelationship between motivation to follow a healthy diet and self-efficacy to adhere to the Mediterranean diet with life satisfaction over time. The sample consisted of cardiovascular patients who were assessed at three measurement moments (NT1 = 755; NT2 = 593; NT3 = 323, average interval time: nine months). Correlation analyses showed that self-efficacy, motivation, and life satisfaction followed a pattern of positive relations across the three measurements. A time effect over the study variables was also observed. The results of path analyses showed that self-efficacy positively predicted autonomous motivation, which in turn was associated with patients’ life satisfaction. This interrelation was stable over a period of 18 months. Moreover, life satisfaction predicted self-efficacy nine months later. Psychological interventions might be a positive resource for cardiovascular patients, since psychological variables influence their life satisfaction and their subsequent quality of life in their new health condition.
Temporal Normal Distribution Functions

Specular aliasing can make seemingly simple scenes notoriously hard to render efﬁciently: small geometric features with high curvature and near specular reﬂectance result in tiny lighting features which are difﬁcult to resolve at low sample counts per pixel. LEAN and LEADR mapping can be used to convert geometric surface detail to anisotropic surface roughness in a preprocess. In scenes including ﬂuid simulation this problem is particularly apparent with fast moving elements such as spray particles, which are typically represented as participating media in movie rendering. Both approaches, however, are only valid in the far-ﬁeld regime where the geometric detail is much smaller than a pixel, while the challenge of resolving highlights remains in the meso-scale. Fast motion and the relatively long shutter intervals, commonly used in movie production, lead to strong variation of the surface normals seen under a pixel over time aggravating the problem. Recent specular anti aliasing approaches preintegrate geometric curvature under the pixel footprint for one speciﬁc ray to achieve noise free images at low sample counts. We extend these to anisotropic surface roughness and to account for the temporal surface normal variation due to motion blur. We use temporal derivatives to approximate the distribution of the surface normal seen under a pixel over the course of the shutter interval. Furthermore, we discuss how this can afterwards be combined with the surface BSDF in a practical way
THE INTRINSIC RATE OF NATURAL INCREASE OF THE GREEN PEACH APHID, MYZUS PERSICAE (SULZER) (HOMOPTERA: APHIDIDAE), ON COLLARDS (BRASSICA OLERACEA L.)

Demographic analysis of a species population can be useful in gaining insight into its dynamics in a particular environment. The calculated intrinsic rate of increase of a population may be valuable in predicting population performance. As a single, discrete value, it serves as a quantitative measure, or ecological index, of the response of a species to a set of environmental conditions (Birch 1948; Messenger 1964).
Protein phosphatase 1cγ is required in germ cells in murine testis

The protein phosphatase 1cγ (PP1cγ) gene is required for spermatogenesis. Males homozygous for a null mutation are sterile, and display both germ cell and Sertoli cell defects. As these two cell types are physically and functionally intimately connected in the testis, the question arises as to whether the primary site of PP1cγ action is in Sertoli cells, germ cells, or both. We generated chimeric males by embryo aggregation to test whether wild type Sertoli cells are capable of rescuing mutant germ cells. To distinguish between the desired XY‐XY chimeras and uninformative XX‐XY chimeras, we designed an adaptation of the single nucleotide primer extension (SNuPE) assay. None of the XY‐XY chimeras sired pups derived from mutant germ cells, indicating that the protein is required in germ cells for production of functional sperm. Analysis of a chimeric testis revealed intermediate phenotypes when compared with PP1cγ−/− testes, suggestive of cell nonautonomous effects. We conclude that PP1cγ is required in a cell autonomous fashion in germ cells. There may be an additional cell nonautonomous role played by this gene in testes, possibly mediated by defective signaling between germ cells and Sertoli cells. Mol. Reprod.

GEOGRAPHIC VARIATION IN THE SONG OF WILLOW FLYCATCHERS: DIFFERENTIATION BETWEEN EMPIDONAX TRAILLII ADASTUS AND E. T. EXTIMUS

Abstract The vocal signatures of the primary song form (“fitz-bew”) of the endangered Southwestern Willow Flycatcher (Empidonax traillii extimus) and its northern counterpart, E. t. adastus, are distinctive. Songs of the extimus subspecies are longer (total song, note, internote) and frequencies at maximum amplitude are lower than those of adastus. I used vocal evidence to clarify the distributional limits of the Southwestern Willow Flycatcher and that of the geographically adjacent subspecies, E. t. adastus. Unweighted pair-group method using averaging (UPGMA) cluster analysis and canonical discriminant analysis revealed that (1) low elevation, southerly desert populations (Arizona, New Mexico, and southern Utah) have a unique vocal identity corresponding to populations in the range of E. t. extimus; (2) northerly song groups (Oregon, Colorado, and northern Utah) share a different song type corresponding to populations in the range of E. t. adastus; and (3) a departure from vocal and morphological congruence occurs for a population of high-elevation Arizona birds that, although in the currently accepted range of E. t. extimus, sings songs acoustically similar to more northern populations (E. t. adastus). Multiple regression of song distance on latitude and elevation, and a comparison of a matrix of song distances with a matrix of latitude and elevation dissimilarities, demonstrated that song populations sort out by both latitude and elevation: birds with the vocal identity of extimus occur as far north as 37°N if at low elevation, and those acoustically similar to adastus occur as far south as 33.7°N if at high elevation. The vocal background of northern New Mexico birds appears to be intermediate between that of extimus and adastus, suggesting that northern New Mexico is a zone of intermixing and intergradation between the subspecies. Pure forms of E. t. extimus apparently do not occur in Colorado because even the southernmost populations are acoustically similar to more northerly populations of adastus. A low-elevation population in western Colorado, however, stands apart from other adastus populations, suggesting moderate introgression of extimus genes into the adastus gene pool.
What factors are associated with obesity‐related health behaviours among child refugees following resettlement in developed countries? A systematic review and synthesis of qualitative and quantitative evidence

Refugee children are likely to become less active and eat more unhealthily after their resettlement in developed countries. This review aims to identify and synthesize research about factors that influence unhealthy behaviours related to obesity in this population. Six electronic databases were searched systematically to identify studies that sampled refugee children or parents of refugee children aged 2 to 16 years who have resettled in a developed country. Methodological and cultural study quality was assessed and factors associated with obesity‐related health behaviours investigated. Twenty studies fulfilled the inclusion criteria. Five major themes, representing factors influencing health behaviours, were identified from the data synthesis process: Acculturation, Environmental, Socioeconomic, Cognitive, and Family. The analysis revealed that refugee's health behaviours are influenced by several complex factors that are common to immigrant groups but have a greater influence among refugees. The review also revealed parental practices influence the health behaviours of children, especially those aged 2 to 10 years. Research is needed to understand further the role that parents have in influencing health behaviours and weight trajectories of children following resettlement.
Selective Inactivation of Viruses with Femtosecond Laser Pulses and its Potential Use for in Vitro Therapy

Introduction: Traditional biochemical and pharmaceutical methods employed today encounter problems of clinical side effects and drug resistance, and their use is becoming limited. Therefore, it has become important and necessary to develop new, alternative strategies to combat viral diseases.Materials and Method: A variety of viruses including M13 bacetriophage (nonenveloped ssDNA), tobacco mosaic virus (nonenveloped ssRNA), human papillomavirus (nonenveloped dsDNA) and human immunodeficiency virus (enveloped ssRNA), together with human red blood cells, Jurkat T-cells and mouse dendritic cells in their buffer solutions have been irradiated with near-infrared subpicosecond laser pulses in vitro.Results: A window of laser power density, approximately between 1 GW/cm2 and 10 GW/cm2, has been observed that allows killing the viral particles while leaving mammalian cells unharmed.Conclusion: The ultrashort pulsed laser technology may have great potential for disinfection of blood components.
TULUNGAN: A Consensus-Independent Reputation System for Collaborative Web Filtering Systems

Web filtering systems allow or prohibit access to websites based on categories (e.g., pornography, violence, sports, etc.). Categorization of websites can be done automatically or manually. Automatic categorization is prone to under- and over-blocking. On the other hand, manual approach is typically performed by a limited number of people making it not scalable. Collaborative web filtering systems, a variation of manual categorization, allow anyone to categorize websites in order to determine which domain these sites belong (e.g., pornography, violence, sports, etc.). This attempts to solve the scalability issue of the typical manual method. The approach offered by collaborative web filtering relies heavily on the contribution of users in order to make the system scalable and less prone to errors. However, its success is greatly dependent on user cooperation. To promote cooperation, reputation system can be used in web filtering. A previous study called Rater-Rating promotes cooperation and explores the use of a user-driven reputation system that measures both the contributor and rater reputation of users of a collaborative web system. However, Rater-Rating is consensus dependent. If the number of malicious users are more than their good counterparts, the reputation system can be defeated. In other words, the system can mistakenly give malicious users a high reputation value. This study discusses a reputation system called Tulungan that is consensus-independent. It can detect the presence of malicious users even if the number of their good counterparts are fewer. A simulation result that compares the effectiveness of Tulungan relative to Rater-Rating is presented in this paper. The simulation shows that Tulungan is still effective even with 25% good users while Rater-Rating requires at least 50% good users to be effective. Keywords: Reputation System Web Filtering
A New Species of Tetramicra (Orchidaceae: Laeliinae) from Baracoa, Eastern Cuba

Abstract A new orchid species, Tetramicra riparia is described from eastern Cuba. The new taxon has intermediate traits between the two subgenera of Tetramicra currently accepted. In fact, the most useful feature to distinguish T. riparia from its congeneric species (the combination of a repent growing habit with a completely entire labellum) is also the main morphological obstacle for classifying it at a subgeneric level. Nevertheless, the classification of the new species in Tetramicra subgenus Tetramicra is supported by the phylogenetic relationships found for a subset of Broughtonia alliance species. In addition, the ecology and conservation status of the new orchid species is discussed and a key for field identification is provided.
Data and Text Mining Help Identify Key Proteins Involved in the Molecular Mechanisms Shared by SARS-CoV-2 and HIV-1

Viruses can be spread from one person to another; therefore, they may cause disorders in many people, sometimes leading to epidemics and even pandemics. New, previously unstudied viruses and some specific mutant or recombinant variants of known viruses constantly appear. An example is a variant of coronaviruses (CoV) causing severe acute respiratory syndrome (SARS), named SARS-CoV-2. Some antiviral drugs, such as remdesivir as well as antiretroviral drugs including darunavir, lopinavir, and ritonavir are suggested to be effective in treating disorders caused by SARS-CoV-2. There are data on the utilization of antiretroviral drugs against SARS-CoV-2. Since there are many studies aimed at the identification of the molecular mechanisms of human immunodeficiency virus type 1 (HIV-1) infection and the development of novel therapeutic approaches against HIV-1, we used HIV-1 for our case study to identify possible molecular pathways shared by SARS-CoV-2 and HIV-1. We applied a text and data mining workflow and identified a list of 46 targets, which can be essential for the development of infections caused by SARS-CoV-2 and HIV-1. We show that SARS-CoV-2 and HIV-1 share some molecular pathways involved in inflammation, immune response, cell cycle regulation.
Comparison of AFLP and SSR for Genetic Diversity Analysis of Brassica napus Hybrids

The AFLP and SSR markers were used to estimate the genetic diversity of 25 Brassica napus hybrids attending Guizhou regional test. The fingerprints obtained with both the AFLP and SSR markers revealed high levels of heterozygosity. Nine AFLP primer combinations produced 16 loci, while 11 SSR primer pairs generated 22 loci. The mean of expected heterozygosity, Shannon’s information index, and genetic differentiation obtained by SSR were higher than those by AFLP, indicating that the SSR methodology evaluated genetic diversity among B. napus more efficiently than the AFLP approach. The higher level of genetic diversity detected by SSR markers was contributed to the lower genetic similarity estimates based on SSR markers (mean 0.69) as compared to AFLP markers (mean 0.73). While the AFLP technique was suitable for identification and DNA fingerprinting of B. napus germplasm. Based on AFLP and SSR analysis, it was concluded that B. napus hybrids had high level genetic diversity. Keyword: AFLP, Brassica napus, Genetic diversity, Hybrid, SSR
Feasibility and Validity of the Actiheart Activity Monitor in Children Who Were Hospitalized With Cancer Coadmitted With Classmates: A RESPECT Study

An investigation of the feasibility of the Actiheart-monitor to determine total daily energy expenditure and the validity of the Actiheart-step-test as an accurate estimate of peak oxygen uptake. Purpose: We investigated the feasibility of the Actiheart monitor to determine total daily energy expenditure and the validity of the Actiheart step test as an accurate estimate of peak oxygen uptake. Methods: O2 peak was estimated with the Actiheart step test and compared with a cardiopulmonary exercise test. Total daily energy expenditure was measured using the Actiheart monitor on days with and without classmate coadmission. Results: Of 26 eligible measurement periods (15 children), 89% participated and 91% could participate safely; however, 35% fulfilled demands for valid monitoring. The percentage of children not completing the monitoring period was 10% (attrition) and adherence to classmate visits was 84%. Forty-eight percent of the measurement periods provided data, and only 27% was calibrated data. Actiheart step test significantly overestimated O2 peak compared with the Cardio Pulmonary Exercise Test. Conclusion: Measuring total daily energy expenditure using Actiheart is not feasible, nor implementable in children with cancer. Furthermore, the Actiheart step test is not a valid test to estimate O2 peak in children with cancer.
