Isolation and identification of phytase-producing Bacillus and Enterobacter species from Nigerian soils

The bioavailability of phosphorus and other nutrients in feed for monogastrics is restricted by the presence of phytate. Exogenous supply of phytase produced by bacteria and other microbes can enhance the bioavailability of these nutrients and reduce phosphorus pollution. The objective of the study was to isolate bacteria with phytase-producing potentials from soil; which may be employed for the bioavailability of phosphorus and other nutrients in feed for monogastrics in Nigeria. Top soil samples were collected from two dumpsites in Lagos, Nigeria and bacteria were isolated and screened for potentials to produce phytase. The isolates with phytase potential were primarily identified by their cultural and biochemical characteristics and then confirmed using the 16S rRNA sequencing, after which their expressed phytases were quantified. A total of six isolates belonging to three species were identified as phytase producers. Sequence data analyses revealed these to be Bacillus subtilis (2), Bacillus amyloliquefaciens (3) and Enterobacter cloacae (1) with accession numbers MH879827 and MH879832; MH879828, MH879830 and MH879831; and MH879829 respectively. Phenotypic phytase activity was highest in E. cloacae ODS 29 (9.69 ± 0.04 U/ml) and least in B. subtilis ODS 10 (8.83 ± 0.02 U/ml). In conclusion, phytase-producing Bacillus and Enterobacter species were isolated and characterized from Nigerian soils. These bacteria species could be used in biotechnological applications.

The role of stimulus-based cues and conceptual information in processing facial expressions of emotion

Face shape and surface textures are two important cues that aid in the perception of facial expressions of emotion. Additionally, this perception is also influenced by high-level emotion concepts. Across two studies, we use representational similarity analysis to investigate the relative roles of shape, surface, and conceptual information in the perception, categorisation, and neural representation of facial expressions. In Study 1, 50 participants completed a perceptual task designed to measure the perceptual similarity of expression pairs, and a categorical task designed to measure the confusability between expression pairs when assigning emotion labels to a face. We used representational similarity analysis and constructed three models of the similarities between emotions using distinct information. Two models were based on stimulus-based cues (face shapes and surface textures) and one model was based on emotion concepts. Using multiple linear regression, we found that behaviour during both tasks was related with the similarity of emotion concepts. The model based on face shapes was more related with behaviour in the perceptual task than in the categorical, and the model based on surface textures was more related with behaviour in the categorical than the perceptual task. In Study 2, 30 participants viewed facial expressions while undergoing fMRI, allowing for the measurement of brain representational geometries of facial expressions of emotion in three core face-responsive regions (the Fusiform Face Area, Occipital Face Area, and Superior Temporal Sulcus), and a region involved in theory of mind (Medial Prefrontal Cortex). Across all four regions, the representational distances between facial expression pairs were related to the similarities of emotion concepts, but not to either of the stimulus-based cues. Together, these results highlight the important top-down influence of high-level emotion concepts both in behavioural tasks and in the neural representation of facial expressions.
Analysis of the Clinical Features of Critical Obstetric Cases After the "Two-Child Policy" was Fully Implemented

Objective: To analyse the changes in the clinical features of critical obstetric cases after the "two-child policy" was fully implemented. Study Design: Retrospective analysis was used. Results: In the study group, the percentage of pregnant women who were older (35~40 years (27.8% vs 26.8%), over 40 years (8.6% vs 5.7%)), and multipara (67.8% vs 47.8%). The major diagnoses for intensive care unit transfer were postpartum haemorrhage. In the two groups, the prevalence of WHO near-miss criteria critical scores was 83.5% vs 76.6%. ICU hospitalization time (2.8 days vs 4 days) and total hospitalization time (12 days vs 15 days). In the study group, the number cases with blood loss below 3000 ml was higher than that in the control group (47.3% vs 30.6%). The number of cases with blood transfusion volume greater than 2000 ml was lower than that in the control group (39.8% vs 60.5%). Postpartum haemorrhage was mainly due to placental previa/placental implantation and was significantly increased in the study group (61.6% vs. 44.2%,), and the prevalence was higher in individuals who underwent hysterectomy (31.5% vs. 24.2%). Conclusion: Under the new policy, the epidemiological characteristics of critical obstetric cases should be considered, and the effective critical care score should take into account not only the utilization rate, turnover rate and length of stay in the ICU but also the economic benefits, planned blood use, length of stay and cost of stay to minimize the incidence of critical cases and reduce maternal mortality.
Water molecules migration at oil–paper interface under the coupling fields of electric and temperature: a molecular dynamics study

ABSTRACT Moisture is an important factor affecting the insulation properties of transformers. Due to the limitations of macroscopic experimental methods, the diffusion of water at oil–paper interface cannot be accurately measured. Therefore, molecular dynamics method was used in this work to establish oil–paper layer model of 105 atoms. Through jointly analysing the aggregation degree, diffusion coefficient, free volume as well as radial distribution function of water molecules, the diffusion mechanism of water molecules at oil–paper interface was studied. The results show that when the initial water content in paper was high, water molecules would accumulate at oil–paper interface to form the local high-water region during heating. The polarisation of the electric field strengthened the hydrogen bonding interaction between water molecules and increased the probability of occurrence of the high-water region. Meanwhile, electric field reduced the free volume and diffusion coefficient of water molecules and rendered its diffusion coefficient anisotropic. What’s more, when the electric field was combined with the temperature field, the electric field played a leading role in the diffusion of water molecules while the temperature field was less affected. Diffusion coefficients of water molecules at different temperatures from molecular dynamics simulations were well consistent with experimental results, which verified the rationality of the model.

Biological Effect of some Herbs in Improvement of Anemia in Rats

The potential health benefits of Safforn (Crocus sativus), Ginger (zingiber officinale) andCumin (Cuminumcyminum ) powder as functional food supplement to improve iron absorption as well as to treat anemia associated with deficiency in iron intake were evaluated in rats. Four experimental groups were fed on diet supplemented with 5% of tested herbs and 1%iron gluconate for 4 week versus the control rats group fed on basal diet free in iron as positive control group and the group fed on basal diet as negative control.At the end of the experiment, rat groups fed herbs supplemented diets were characterized by the level of serum iron, measured levels of hemoglobin, hematocrit and ferritin. Liver functions was assessed by estimation of plasma concentration of enzymes activities of aspartate amino transferase (AST), alanine amino transferase (ALT), uric acid, creatinine, MDA level, GSH and GSSG activity.Results showed significant increasing in the level of serum iron, in addition, there were variable increases in the measured levels of hemoglobin, hematocrit and ferritin in herbs fed groups as compared with the positive control group. In addition, there was an improvement in case of tested herbs at the level of 5% for the above parameters as compared to positive control group. These data suggested that saffron followed by ginger, herbs mixtures andcumin powder could improve tested parameters and iron bioavailability when incorporated in daily diets and therefore, could be considered as a very effective food supplement to prevent and treat anemia.
Psychotherapists’ altered states of consciousness

The majority of research that has been conducted around counselling and psychotherapy has been directed towards the evaluation of client outcome and client experience. Studies concentrated solely on therapist experience during the therapeutic encounter are largely in the minority. The purpose of this study was to explicate a deeper understanding of the unusual and unforgettable events that led to dramatic shifts in consciousness experienced by some counsellors and psychotherapists during the therapeutic hour. A study group of six participants was assembled via open invitation. The group comprised of three student counsellors nearing the end of their studies and three qualified therapists of varying degrees of experience. A semi-structured interview process provided transcriptions of the participant experiences, and an interpretative phenomenological analysis was conducted. This study found that the willingness to be open to the presence and essence of another, on both sides of the therapeutic dyad, had the potential to contribute to the intense, powerful and profound experiences arising in the therapist. In all cases, the unusual events and altered states led to the deepening of the healing potential within the therapy whilst simultaneously providing developmental propulsion for each practitioner.
Physiological responses of the two blueberry cultivars to inoculation with an arbuscular mycorrhizal fungus under low-temperature stress

ABSTRACT Effects of the arbuscular mycorrhizal fungus (AMF), Glomus mosseae, on growth, antioxidant, osmoregulation, and nutrition were investigated in “Britewell” (Vaccinium ashei) and “Misty” (Vaccinium corymbosum) plants exposed to low temperature (10°C). At low temperature, the two cultivars showed similar decreases in leaf concentrations of soluble sugars, phosphorus (P), and potassium (K). However, similar increases were observed in levels of leaf antioxidants, malondialdehyde (MDA), hydrogen peroxide (H2O2), superoxide anion radical (), and proline. AM inoculation increased leaf activities of superoxide dismutase, ascorbate peroxidase, guaiacol peroxidase, ascorbate, and glutathione, but decreased leaf concentrations of , MDA, and H2O2 in the two cultivars. AMF caused greater changes in leaf composition in “Britewell. ” AM-inoculated “Britewell” and “Misty” plants had higher concentrations of soluble sugar, proline, P, and K than non-AM-inoculated plants, especially in the former cultivar. These results indicate that G. mosseae has the potential to enhance resistance of “Britewell” blueberry plants against low-temperature stress.
THE IMPACT OF UNIVERSITY AND HOSPITAL SUPPORT ON NURSING INTERN SATISFACTION

THE IMPACT OF UNIVERSITY AND HOSPITAL SUPPORT ON NURSING INTERN SATISFACTION The year-long clinical internship is important for undergraduate nursing students who are completing their four years of university study. It gives them an opportunity to work and practice the tasks assigned to them by different units and departments. To ensure that nursing students have a positive working environment, it is essential to examine the impact of support from both university faculty and hospital staff on nursing intern satisfaction. To assess this, cross-sectional surveys were distributed to nursing interns after they completed their internships. Researchers collected descriptive data and looked for correlations, later creating a model designed to measure direct or indirect impacts of faculty and hospital support on nursing intern satisfaction. This analysis, along with a regression model with goodness-of-fit test, was calculated using SPSS version 24 and AMOS version 24. In total, 138 students responded to the questionnaire. The majority of the participants were female, with 88 participants (63.8%), while only 50 males (36.2%) participated. Analysis showed a strong correlation between hospital support for nursing interns and interns' perception of a positive working environment, as well as a good correlation between positive working environment and overall nursing intern satisfaction. On the other hand, weak correlations show that university faculty had little perceived impact on whether or not nursing interns felt they worked in a positive environment. The study also confirmed that the hospital setting has impact significant on clinical positive environment. Knowing about what satisfies nursing interns helps nursing educators to devise internship programs that will improve the process for future cohorts.
Corporate Social Responsibility on Financial Performance: A Study of the Bangladeshi DSE Listed Private Commercial Banks

The fundamental purpose of the study is to examine the impact of corporate social responsibility (CSR) on the financial performance (FP) of Private Commercial Banks (PCBs) in Bangladesh. The study uses a simple random sampling technique. Ten (10) PCBs are selected as samples for the study from the Dhaka Stock Exchange (DSE) listed companies. Statistical analysis tools such as regression, analysis of variance (ANOVA), and correlation are applied to collected data to examine CSR's impact on selected banks' financial performance. In the study, net profit after tax (NPAT), earnings per share (EPS), net asset value per share (NAVPS), return on assets (ROA), return on equity (ROE), and market value per share (MVPS) are considered as dependent variables and the independent variable, corporate social responsibility (CSR). The findings reveal that the EPS, NAVPS and MVPS of the selected banks are significantly influenced by CSR 56.4, 62.0, and 59.8 percent, respectively. In contrast, CSR has an insignificant relationship with NPAT, ROA, and ROE. The study also indicates a high degree positive and statistically significant correlation between CSR and financial performance (EPS, NAVPS, and MVPS). CSR influences financial performance essentially, so considering social benefits, the banks should perform CSR activities emphasizing educational, environmental, and health issues.
lncRNA_Mdeep: an alignment-free predictor for long non-coding RNAs identification by multimodal deep learning

Background: Long non-coding RNAs (lncRNAs) play crucial roles in diverse biological processes and human complex diseases. Distinguishing lncRNAs from protein-coding transcripts is a fundamental step for analyzing lncRNA functional mechanism. However, the experimental identification of lncRNAs is expensive and time-consuming. Results: In this study, we present an alignment-free multimodal deep learning framework (namely lncRNA_Mdeep) to distinguish lncRNAs from protein-coding transcripts. LncRNA_Mdeep incorporates three different input modalities (i.e. OFH modality, k-mer modality, and sequence modality), then a multimodal deep learning framework is built for learning the high-level abstract representations and predicting the probability whether a transcript is lncRNA or not. Conclusions: LncRNA_Mdeep achieves 98.73% prediction accuracy in 10-fold cross-validation test on human. Compared with other eight state-of-the-art methods, lncRNA_Mdeep shows 93.12% prediction accuracy independent test on human, which is 0.94%~15.41% higher than that of other eight methods. In addition, the results on 11 cross-species datasets show that lncRNA_Mdeep is a powerful predictor for identifying lncRNAs.

Centimeter-Sized Inorganic Lead Halide Perovskite CsPbBr3 Crystals Grown by an Improved Solution Method

As a member of the lead-halide perovskite family, inorganic perovskite CsPbBr3 exhibits excellent optical and electrical properties with higher stability to the environment. However, former efforts to obtain large-size CsPbBr3 single crystals with satisfactory quality using low temperature solution methods reached limited results. In this work, we have studied the growth of CsPbBr3 crystals using the antisolvent vapor-assisted crystallization (AVC) method. By adjusting the mole ratio of PbBr2 and CsBr, the phase diagram of the final products is acquired. Five regions are identified, including the Cs4PbBr6 single phase region, Cs4PbBr6 and CsPbBr3 two phases region, CsPbBr3 single phase region, CsPbBr3 and PbBr2·2[(CH3)2SO] metastable two phases region, and CsPbBr3 and PbBr2·2[(CH3)2SO] two phases region. Three methods are adopted to improve the size and crystalline quality of CsPbBr3. The growth rate is effectively tailored by diluting the antisolvent MeOH solution using DMSO to reduce the MeOH vapor pres.
Lightweight Aluminium Sandwich Structures for Marine Vehicles

One of the most important design strategies for increasing the speed and/or efficiency of marine vehicles is that of weight reduction. This can be achieved by optimising structural design via judicious distribution of the most apt materials and via the application of innovative lightweight structures. Sandwich structures are ideal candidates for structural lightening since they provide excellent mechanical properties at low densities, and a wide range of properties via intelligent selection of face-sheet and core materials, and configurations. Further, sandwich structures selection for marine vehicles needs to consider manufacturing feasibility for large structures, sustainability issues and materials compatibility with the aggressive marine environment. As a possible alternative to the ubiquitous glass reinforced plastic (GRP) fibre composite sandwich materials used for marine vehicles, all-aluminium sandwich structures have several attractive properties such as light weight, high mechanical properties, sustainability, and corrosion resistance. Common architectures for metallic cores include: honeycomb, foam, corrugated and lattice. This work aims to evaluate the effectiveness of aluminium honeycomb sandwich structures in marine applications by providing a comparison with other lightweight solutions. Bending stiffness was used as the criterion to select honeycomb sandwich panels allowing valid comparisons with typical marine GFRP sandwich panels. A case study based on a possible replacement of a GFRP ship balcony with an equivalent aluminium honeycomb sandwich structure was introduced. The proposed balcony was analysed with a simplified numerical model, which gives useful information for the design of the proposed structure and the experimental set up of full scale tests. The acquired information can be applied to support the design of lightweight honeycomb sandwich panels to be used for balconies, decks, floors, ceilings and other structural elements of marine vehicles.

The results showed that the catalyst possessed excellent magnetic responsivity, and it could be recovered by external magnetic field. The magnetic catalyst was also characterized by ICP, TG-DTG, XRD, SEM, EDS, TEM and N2 absorption-desorption. It was found that the catalyst showed a unique porous structure. The reaction conditions affecting biodiesel yield were investigated, the biodiesel yield reached 94% was obtained under the optimal conditions. The biodiesel yield was still above 82% after 7 times of regeneration, and the catalyst can be easily separated and recycled.
Mechanisms of Action And Effects of Pulsed Electromagnetic Fields (PEMF) in Medicine

Pulsed Electromagnetic Field (PEMF) therapy is a non-invasive and non-thermal treatment widely used nowadays to treat various types of disorders and traumas, both in humans and animals. Initially applied only for wound healing, today it finds many applications in medicine for the treatment of bone fractures, arthritis, inflammation, edema, and pain. Although their mechanisms of action are still being studied today, and mainly related to the calcium signaling pathway, they are effective in the adjuvant treatment of many human diseases in different medical specialties. This work aims to report the main evidence and research in the medical field with particular reference to the application of PEMF to some medical specialties as regenerative medicine (wound care), sports medicine, orthopedics, and physiotherapy. Finally, this work also wanted to deepen one of the most recent applications of PEMF in the field of complex diseases, i.e. in the adjuvant treatment of cancer. Pulsed electromagnetic field therapy may play an important role in medicine as a complementary treatment for various human diseases and, by deepening the studies in the future, it will be possible not only to understand the exact mechanisms of action but also to extend its application to other pathologies both in the medical and veterinary fields.
Podophyllotoxin extraction from Linum usitatissimum plant and its anticancer activity against HT-29, A-549 and MDA-MB-231 cell lines with and without the presence of gold nanoparticles

In recent years, gold nanoparticles (Au-NPs) have been taken into consideration in nanomedicine due to their excellent biocompatibility, chemical stability and promising optical properties. In this research, podophyllotoxin conjugated with gold nanoparticles (Au-NPs-POT) was synthesized and the conjugation of POT with Au-NPs was confirmed using scanning electron microscopy, mass spectrometry and Fourier transform infrared spectroscopy. The anticancer effects of the product on preclinical models of lung, colon and breast cancers were investigated using MTT test. The analyses showed a direct dose–response relationship. It was found that higher concentrations of POT have more positive effects on the inhibition of cancer cell growth. At POT concentrations of 1, 2.5, 5, 7.5, 10, 15 and 20 mg ml−1, approximately 50% of the growth of colorectal, lung and breast cancer cell lines was inhibited, while similar results were obtained in the presence of 1, 2, 3, 4 and 5 μg ml−1 Au-NPs-POT. Au-NPs-POT exhibited the lowest cytotoxicity due to the presence of POT. The anticancer feature of Au-NPs-POT proved the potential to develop better anticancer therapeutics and to open new avenues for treatment of cancers.
