Continuation of Teletherapy After the COVID-19 Pandemic: Survey Study of Licensed Mental Health Professionals
Authors: Gangamma Rashmi , Walia Bhavneet , Luke Melissa , Lucena Claudine
Published: May 2022

Background

The use of teletherapy has exponentially increased in the context of the ongoing COVID-19 pandemic. Studies on teletherapy documented substantial benefits of accessibility and convenience even before the start of the pandemic. Although recent studies show that this modality of therapy delivery is here to stay, few have studied who will most benefit from this trend.

Objective

In this paper, we report predictors of continued teletherapy usage in a sample of licensed mental health professionals in the United States during a time period when pandemic-related restrictions began diminishing. As such, it is one of the first studies to examine factors related to continued benefits of teletherapy postpandemic.

Methods

Participation from licensed mental health professionals was sought on listservs of national organizations of multiple mental health organizations. Data were collected via an anonymous link to a survey on Qualtrics between January 2021 and April 2021. Participants responded to questions on therapist demographics, practice setting, experiences of shifting to teletherapy, perspectives on continued use of teletherapy, and their client characteristics. Findings related to client characteristics that predicted continued teletherapy usage are presented here.

Results

A total of 186 individuals consented to participate in the survey, with a final sample of 114 with complete data. A majority of participants identified as female (92/114, 80.7%), White (94/114, 82.5%), and having a master's degree (75/114, 65.5%) from a nationally accredited program (106/114, 93%). Data were analyzed using heteroskedastic regression modeling with client-related factors as predictors. Two models were run with and without distance travelled by clients as a control variable. Model estimates from both models showed that continued use of teletherapy postpandemic was predicted by the following factors: higher percentage of clients from rural areas, younger and older adult clients, clients with Medicare, and clients with marginalized gender and religious/spiritual identities. Significantly, having a higher percentage of clients from lower socioeconomic status, a higher percentage of those with Medicaid coverage, and a higher percentage of couples and families as clients predicted decreased use of teletherapy postpandemic.

Conclusions

Findings from the study suggest that while some groups of clients are more likely to continue to receive benefits of teletherapy, vulnerable groups such as those in lower socioeconomic conditions, Medicaid beneficiaries, and those who seek couple and family therapy may be less likely to be served by it. These differences point to a need to address factors driving telehealth care disparities such as access to technology, housing, and childcare issues, as well as the need for continued training for licensed professionals.

Social media integration into research has increased, and 92% of American social media participants state they would share their data with researchers. Yet, the potential of these data to transform health outcomes has not been fully realized, and the way clinical research is performed has been held back. The use of these technologies in research is dependent on the investigators’ awareness of their potential and their ability to innovate within regulatory and institutional guidelines. The Brown-Lifespan Center for Digital Health has launched an initiative to address these challenges and provide a helpful framework to expand social media use in clinical research.

Artificial Intelligence–Assisted Diagnosis of Anterior Cruciate Ligament Tears From Magnetic Resonance Images: Algorithm Development and Validation Study (Preprint)
Authors: Chen Kun-Hui , Yang Chih-Yu , Wang Hsin-Yi , Ma Hsiao-Li , Lee Oscar Kuang-Sheng
Published: May 2022

BACKGROUND

Anterior cruciate ligament (ACL) injuries are common in sports and are critical knee injuries that require prompt diagnosis. Magnetic resonance imaging (MRI) is a strong, noninvasive tool for detecting ACL tears, which requires training to read accurately. Clinicians with different experiences in reading MR images require different information for the diagnosis of ACL tears. Artificial intelligence (AI) image processing could be a promising approach in the diagnosis of ACL tears.

OBJECTIVE

This study sought to use AI to (1) diagnose ACL tears from complete MR images, (2) identify torn-ACL images from complete MR images with a diagnosis of ACL tears, and (3) differentiate intact-ACL and torn-ACL MR images from the selected MR images.

METHODS

The sagittal MR images of torn ACL (n=1205) and intact ACL (n=1018) from 800 cases and the complete knee MR images of 200 cases (100 torn ACL and 100 intact ACL) from patients aged 20-40 years were retrospectively collected. An AI approach using a convolutional neural network was applied to build models for the objective. The MR images of 200 independent cases (100 torn ACL and 100 intact ACL) were used as the test set for the models. The MR images of 40 randomly selected cases from the test set were used to compare the reading accuracy of ACL tears between the trained model and clinicians with different levels of experience.

RESULTS

The first model differentiated between torn-ACL, intact-ACL, and other images from complete MR images with an accuracy of 0.9946, and the sensitivity, specificity, precision, and F1-score were 0.9344, 0.9743, 0.8659, and 0.8980, respectively. The final accuracy for ACL-tear diagnosis was 0.96. The model showed a significantly higher reading accuracy than less experienced clinicians. The second model identified torn-ACL images from complete MR images with a diagnosis of ACL tear with an accuracy of 0.9943, and the sensitivity, specificity, precision, and F1-score were 0.9154, 0.9660, 0.8167, and 0.8632, respectively. The third model differentiated torn- and intact-ACL images with an accuracy of 0.9691, and the sensitivity, specificity, precision, and F1-score were 0.9827, 0.9519, 0.9632, and 0.9728, respectively.

CONCLUSIONS

This study demonstrates the feasibility of using an AI approach to provide information to clinicians who need different information from MRI to diagnose ACL tears.

Authors: Di Filippo Marzia , Avellone Alessandro , Belingheri Michael , Paladino Maria Emilia , Riva Michele Augusto , Zambon Antonella , Pescini Dario
Published: May 2022

BACKGROUND

Over the last few years, increasingly studies focused on the development of mobile apps as complementary tools to existing pharmacovigilance traditional surveillance systems for improving and facilitating adverse drug reactions reporting.

OBJECTIVE

In this study, we evaluated the potentiality of a new mobile app called vaxEffect@UniMiB in increasing the spontaneous citizenship participation to an adverse reactions drug data collection campaign. In particular, we evaluated the reporting rate of adverse reactions in a cohort of academic subjects vaccinated for COVID-19, together with its capability to enable longitudinal studies by analysing per subject time series.

METHODS

vaxEffect@UniMiB was developed for both Android and iOS devices. The mobile app asks users to send their medical history and, upon every vaccine administration, their vaccination data and the adverse symptoms that occurred within seven days after the vaccination. The app sends data over the web to an application server. The web server, along with receiving all user data, saves them in a SQL database server, and reminds patients to submit vaccine and adverse symptoms’ data by push notifications sent to the mobile app through Firebase Cloud Messaging. On initial startup of the app, a unique user identifier was generated for each respondent, so that its anonymity is completely ensured.

RESULTS

A total of 2733 respondents between the ages of 19 and 80 coming from the University of Milano-Bicocca and the Politecnico of Milan participated in the survey. Overall, we collected the information about vaccination and adverse reactions to the first vaccine dose for 2226 subjects (59.9%), to the second dose for 1610 subjects (43.3%), and, in a non sponsored fashion, to the third dose only for 169 individuals.

CONCLUSIONS

vaxEffect@UniMiB revealed to be the first attempt in performing longitudinal studies to monitor the same subject over time in terms of the reported ADRs after each vaccine administration, while guaranteeing at the same time complete anonymity of the submitted data.
A series of aspects contributed to a positive involvement from people in using this application to report their ADRs to vaccination: ease of use, availability from multiple platforms, anonymity of all the survey participants and protection of the submitted data.

A Revised Hippocratic Oath for The Era of Digital Health (Preprint)
Authors: Meskó Bertalan , Spiegel Brennan
Published: May 2022

BACKGROUND

Physicians have been taking the Hippocratic Oath for centuries. The Oath contains a set of ethical rules designed to guide physicians through their profession; it articulates a set of true north principles that govern the practice of medicine.

OBJECTIVE

The rise of digital health has dramatically changed the practice of medicine in a way that could not have been easily predicted at the time Hippocrates outlined his ethical principles of medicine.

METHODS

We reviewed the points of the Oath and suggested revised sections.

RESULTS

We believe that it now justified to modify the Hippocratic Oath—even if modestly—to reflect the digital health revolution, advances in patient empowerment, and the evolving role of technology in the everyday practice of medicine.

CONCLUSIONS

This way, younger physicians below the digital divide can better relate to the Oath, while older physicians above the digital divide can gain further insights and inspiration from the pledge.

Published: May 2022

The goal of this study was to evaluate the effect of using GeoGebra with the ARCS (Attention, Relevance, Confidence, and Satisfaction) model on academic achievement and motivation. In this regard, an experimental and a control group were constituted. The academic motivation questionnaire (Harter, 1981) was used to measure participant’s motivation. Further, two instances of a multiple-choice questions test on a topic in Geometry were designed to measure student’s academic achievement. In order to collect data, the pre-tests were applied to each group at the beginning of the lessons. The experimental group was taught using GeoGebra and the control group was trained with the traditional teaching method. At the end of the lessons, the post-tests were administered to both groups. The statistical difference between participant’s post-test academic motivation and learning of the experimental and control group was analyzed with ANCOVA after examining the assumptions of this test, namely normality and homogeneity in each group. Results of the study indicated that the scores of academic achievement and motivation in the experimental group were significantly more than that of the control group.

Published: May 2022

Objective: Ayurvedic formulation derived phytomedicine could bring a specific remedy against myocardial infarction (MI) without any side effects. Arjunarishta is a cardio tonic that nourishes and strengthens the myocardial muscle and promotes cardiac function. The preparation of Arjunarishta is modified and it does not involve fermentation. So it is alcohol-free and safe to all age groups. The study of acute toxicity and therapeutic activity of Modified Arjunarishta (MA) in isoproterenol (IPN) induced MI in rats was conducted to bring scientific evidence. Methods: Acute toxicity study: Mice are divided into three groups. Group I-control group; Group II and group III were test groups and they received an oral dose of 1000 mg/kg and 2000 mg/kg of MA, respectively. The experimental mice were observed for behaviour changes and clinical signs. Their body weight was also recorded. At the end of the experiment, blood sample was collected and glucose, liver function test (LFT), renal function test (RFT) and haematology parameters were analysed. Then they also subjected to gross pathological examination of all the major internal organs. Therapeutic study: Rats were divided into six groups. Group 1-normal control; Group 2 (induced)-IPN 85 mg/kg for the first two days; Group 3 (MA low dose)-received IPN as per group 2 followed by MA 200 mg/kg from the 3rd day to the end of the experiment; Group 4 (MA medium dose)-400 mg/kg; Group 5 (MA high dose)-600 mg/kg; Group 6 (Standard)-IPN as per group 2 followed by Arjunarishta 2 ml/kg body weight from the 3rd day to the end of the experiment. The collected serum sample was used for the estimation of myocardium-expressed proinflammatory cytokines. Heart tissue was homogenized for the estimation of calcium and lipid profile. Results: Acute toxicity: There were no signs of toxicity and no significant change in body weight. The value of glucose, RFT, LFT and haematological parameters are remained normal. Histopathological report showed normal architecture. Therapeutic activity: In the heart samples, significantly (p<0.001) increased cholesterol, Triglyceride (TGL), Free Fatty acids (FFA) and calcium in IPN induced groups was noted. They are all significantly (p<0.001) decreased in MA administrated groups of three different groups. In serum sample, a significantly (p<0.001) increased cytokines of Tumor necrosis factor α (TNFα), Interlukins (IL-6, IL-1α and IL-1β) in IPN induced rats was recorded were as they get significantly (p<0.001) decreased in MA administrated groups of three different doses. Conclusion: The results obtained from the acute toxicity experiment concluded that MA was found to be safe for oral administration. The therapeutic experiment results clearly emphasize the beneficial action of MA against IPN induced MI in rats.

Published: May 2022

Cough is a physiological reflex, experienced by every human, is an important protective and defensive mechanism whose action secures the removal of foreign materials and secretions from the airways (larynx, trachea and bronchi). In various circumstances, such as respiratory tract inflammation, viral infections, allergic rhinitis, or inhalation of various irritants, it is unintentionally stimulated and a cough suppressant may be needed to relieve the cough. The currently available cough suppressants (opiates, dextromethorphan, etc.) limit their use in humans due to significant side effects such as constipation, respiratory depression, drowsiness. Lauq Khayar Shambar (LKS) is used as an antitussive in Unani medicine for centuries and is also used to treat various upper respiratory tract ailments such as asthma, dyspnoea, catarrh, productive and dry cough, pharyngitis and laryngitis. So, this review aims to explore the role of LKS in the management of cough.
COMPARATIVE STUDY ON NUTRIENT COMPOSITION AND FUNCTIONAL CHARACTERISTICS OF TROPICAL FRUITS WITH EMPHASIS ON BANANA FRUIT PEEL
Authors: ANJUM SHADMA , SUNDARAM SHANTHY
Published: May 2022

Objective: To determine the nutritional and anti-nutritional components of banana peel at various stages of ripening and compared it with tropical fruits (apple and mango).
Methods: Initially, nutrient values for individual fruits and its peel (Apple, Mango, and Banana) samples were analyzed. The color values (L, a, b, and c*value,) and textural characteristics (hardness, cohesiveness, springiness and adhesiveness) were used to determine the ripening stage. Protein, sugar, carbohydrate, crude fiber, crude fat, tannin, and oxalate content were all evaluated to determine their nutritional and anti-nutritional qualities.
Results: After statistical analysis, it was investigated that banana peels in the unripe stage had lower crude fat content (1.2±0.03%) and moisture content (5.97±0.12%). The amount of crude fiber in banana peel (36.16±0.09%) was found to be high when compared to mango (26.5±0.06%) and apple peel (10.7±0.06%), which greatly boosted its nutritional value. Unripe banana peel has a low K (245.1±0.07 mg/100 gm) and high Mg (566.61±0.07 mg/100 gm) ratio. This increases its potential as an anti-diabetic source. Whereas leaky ripe banana peels have the maximum potassium content (11730±0.09 mg/100 gm), followed by ripe (7288±0.06 mg/100 gm) and unripe (245.1±0.07 mg/100 gm), making them equally nutritionally important.
Conclusion: The investigation concluded that though all fruits are tropical and readily available all year around, but banana are cheaper and nutritionally rich. Banana peel has a low level of anti-nutritional factor, which makes it safe for human consumption. All stages of the banana peel are equally significant. Leaky ripe peels contain many valuable vitamins and minerals, ranging from iron (7.7±0.09 mg/100 gm) to phosphorus (36.6±0.19) to calcium (567.4±0.06 mg/100 gm) to Na (42.5±0.09 mg/100 gm) and K (11730±0.09 mg/100 gm), which can help to enrich soil fertility, and thus could be used as an organic fertilizer. Whereas, unripe banana peels could be used for many therapeutic purposes due to their high fiber, essential fat, and mineral content. Thus, they are not recommended to be thrown and used in for more socio-economic purposes.

Published: May 2022

Objective: Toltrazuril is veterinary medicine, which is extensively used as an antiprotozoal drug. This drug can be analyzed by two sensitive chromatographic, accurate, and reproducible methods that have been developed and validated for the determination of toltrazuril in the presence of its alkaline degradation product. Methods: The first method involves an RP–HPLC separation of the two components, successfully achieved using Eclipse XDB-C18 Column (4.6 x 150 mm, 5 µm), using a mixture of acetonitrile and water (60:40, v/v) as a mobile phase at a flow rate of 1.4 ml/min. quantification was done with UV detector at a wavelength 242 nm UV detection. The second method is based on the separation and quantification of toltrazuril and its alkaline degradation product by TLC-densitometry on TLC silica gel aluminum plates GF254, using dichloromethane: methanol (9.5:0.5, v/v) as the developing system followed by densitometric measurement at 242 nm UV detection. Results: For RP-HPLC linearity of toltrazuril over the concentration range of 12.5–75 µg/ml, the components were well resolved from each other with significant diverse Rt values of 6.17 and 8.62 min for toltrazuril and its degradation product, respectively. While in TLC-densitometry method, the linearity of toltrazuril over the concentration range 0.2-6 µg/spot and the studied components were well resolved from each other with significant different Rf values of 0.33 and 0.52 for toltrazuril and its alkaline degradation product, respectively. For both the developed and validated methods the %RSD was found to be less than 2% and the % recovery was found to be between [98-102 %]. Conclusion: Fortunately, effective separation of the drug from its degradation product was established, along with the determination of toltrazuril as a raw material and the marketed pharmaceutical formulation, such as suspension without any interference. Hence it can be used for routine analysis in various pharmaceutical industries.

Abstract: Earth Tube heat exchanger can be proved as a better substitution to the space heating and HVAC problems that we face in our day to day lives. Earth tube heat exchangers can work in two phases, i.e. as a heater during winter seasons and as a cooler during summer season. ETHE can work more efficiently than traditional HVAC. This project concentrates on computational study of earth tube heat exchanger. The designing calculations were done for appropriate length and area of an earth tube heat exchanger. A model of ETHE was produced on basis of this calculations and dimensions obtained. The model was generated using Solidworks R2021 software. The ETHE model generated was then analysed for thermal stresses, distribution and other parameters. A CFD simulation of model for velocity and flow was carried on. The conclusions obtained show that ETHE works efficiently and can be used as a substitution for traditional HVAC.

Published: May 2022

Abstract: Conventional visual secret sharing (VSS) schemes hide secret images in shares that are moreover published on clarity or are decoded and stored in a digital form. The shares can appear as noise-suchlike pixels or as meaningful images, but it'll arouse dubitation and increase interception threat during transmission of the shares. Hence, VSS schemes suffer from a transmission threat problem for the secret itself and for the actors who are involved in the VSS scheme. To address this problem, we proposed a new fashion for the palette-grounded steganography using a texture with LSB and also a natural-image-grounded VSS scheme (NVSS scheme) that shares secret images via colorful carrier media to cover the secret and the actors during the transmission phase. We contrive the texture conflation process into steganography to hide secret dispatches. In comparison to using a being cover image to hide dispatches, our algorithm hides the source texture image and embeds secret dispatches through the process of print. The natural shares can be prints or hand-painted filmland in digital form or published form. We also propose possible ways to hide the secret to reduce the transmission threat problem for the share. Experimental results indicate that the proposed approach is an excellent result for working the transmission threat problem for the VSS schemes.

Published: May 2022

Abstract: In the current scenario smartphones play a vital role in our daily life, In fact they are a part of our lives. Smartphones can now handle the majority of problems fast and easily. Every person's life has been made simpler and easier as a result of it.Basically this paper focuses on the problem which is faced by the faculties and students during the process of attendance and there are more chances of proxies in the traditional method (using pen and papers). The paper proposed a system that will use AR Marker technology and handle the problem for recording the attendance of the students in school and colleges. The suggested system consists of two applications: one for creating the AR Marker by entering class information via faculty, and another for scanning the QR code via students. The teacher will generate the QR code and present it to the students using a projector, after which the students will simply open the second app and scan the QR code to get their attendance. The Smart Attendance System is cost effective because it does not rely on biometric devices which are expensive. The paper explains how the system authenticates students' identities in order to prevent fraudulent registrations. By changing the QR code every five to ten seconds and just for five minutes, the system is able to reduce the proxy level. If any student fails to show up for class, the professor may display the QR code again. The system is in charge of managing and evaluating all students' attendance. In addition, the system will save the attendance data in XLS and CSV files for future use. Keyword: Smart Attendance System, AR Marker, Attendance System using QR Code, Software as a Service .

This study describes the results of research on the implementation of the Quizizz application in learning with distance learning mode. It has three main objectives 1) to find out how to apply the Quizizz application as an assessment medium based on higher-order thinking skills; 2) the impact of the application of Quizizz as an assessment medium based on higher-order thinking skills on students' learning motivation; and 3) supporting and inhibiting factors for the implementation of Quizizz. This study used a qualitative descriptive approach and data were collected using observation, implementation, interviews, questionnaires, and documentation. The data analysis was carried out by grouping and presenting the data of 69 respondents and drawing conclusions. The use of Quizizz as an assessment medium based on HOT skills is carried out during daily tests, mid-semester, and end-semester tests. Based on the data, it was obtained information that the level of student learning motivation using Quizizz media based on higher-order thinking skills showed an average of 69.91. Furthermore, the supporting factor for the application of Quizizz media is that students are familiar with the use of Quizizz and the many tasks available on Quizizz. The inhibiting factor is that the internet connection at the student's residence still tends to be less supportive of online distance learning.

Published: May 2022

This study aimed to examine the attitudes of Ghanaian student nurses towards mathematics. A sample of 301 undergraduate nursing students at a university in Ghana, selected through census sampling techniques from the first to the third-year students, participated in the study. Data was collected using a 5-point Likert scale questionnaire and analyzed using descriptive and inferential statistics. The study revealed that the students’ attitudes towards mathematics are determined by the value they attach to mathematics and their interest in mathematics. At α=0.01, Spearman's rho correlation coefficient of rs = 0.619 was significant. This indicates that the more value the student nurses attach to mathematics learning, the more interest they will likely have in learning the subject. The coefficient of determination (R2=38%), indicates that the students’ value for mathematics accounts for 38% of the variability in their interest in mathematics.

Global instability as a factor in the change of world order increased gradually. The discussion about a new systemic crisis began already at a time when the world and Europe were still overcoming the consequences of the economic crisis of 2007–2009. However, we faced with not an economic and not even a political crisis, but a systemic destruction of the world order, which will no longer be restored. Ukraine has only shown that it is a weak link, where all global problems are integrated into a single whole and proposed for Russia’s solution.

Published: May 2022

The economy of Vietnam is a socialist-oriented emerging market that heavily depends on agriculture, tourism, raw material exports, and foreign direct investment. Vietnam is industrializing and modernizing from a low starting point with weak and small economic resources. This is one of the huge obstacles to the development of Vietnam’s economy. Therefore, mobilizing and leveraging foreign direct investment are very important. In the COVID-19 pandemic, many large international corporations and enterprises are looking for investment opportunities to diversify their supply chains and limit their overdependence on the Chinese market. Vietnam has emerged as one of the brightest candidates for this capital flow due to its success in epidemic prevention. While foreign direct investment has been declining globally, foreign direct investment in Vietnam has rebounded in the second quarter of 2020 and has been on an upward trend. The real estate market remained an active segment in the third quarter of 2020. This article uses comparison, logical and statistical analysis methods to study foreign direct investment in real estate in Vietnam. The contribution analyzes the factors that influenced the desire of foreign investors to invest in the Vietnamese real estate market, based on publicly available data sources of the Foreign Investment Agency, Vietnam Ministry of Planning and Investment; and the General Statistics Office of Vietnam. Solutions at the state level to stimulate investment in Vietnam are proposed.

Published: May 2022

Aims. Conceptualization of technopolitical sphere impact on recursive processes of public policy; defining key problems that inhibit public authorities from improving digital politics stability essential for developing public policy recursive potential.Methods. The work is based on institutional approach traditional for conducting interdisciplinary research about using informational and communicative technologies in politics and governance. Moreover, it is helpful for considering meaning of public institutes in the scope of conceptualization of technopolitical sphere stability and recursiveness as an attribute of public policy.Results. Recent approaches to understanding the essence of public policy define the efficiency of shaping political agenda, developing and making decisions as more and more dependent on expert knowledge and ways of political participation. Based on the recursiveness as a public policy attribute there is made a point of expert knowledge for building and keeping feedback linking between system elements as a key principle of public policy change as an «epistemic thing». Recursive processes progression depends on stability of technopolitical sphere that rests upon quality, direction and dynamics of institutional change, political inclusiveness. As for Russia, building technopolitical infrastructure necessary for recursive processes is in progress now and meet a wide range of political and governmental rigidity, legal framework insufficiency. In order to overcome it, public authorities shall pay attention to total improving the digital literacy, coordination, legal framework update and developing new institutes of digital intersectoral collaboration.Conclusion. In public policy and its actors recursiveness serves as a principle of systematic monitoring politics and governance which defines evolutional dynamics of these processes. Digital politics creates conditions for building recursive processes into the context of shaping political agenda, developing and making decisions. The research results highlight issues significant for contemporary political science in the context of technopolitical national development and can be enhanced with both theoretical and applied research.

Published: May 2022

The subject of consideration in this article are the state and prospects for the digitalization of public administration in modern Russia. The scale and speed of changes in all spheres of public relations caused by digital technologies is unprecedented, these changes were especially accelerated during the Covid-19 pandemic. They affect these changes and processes of public administration, at the same time, in this area there are differences from the commercial sector, where such a phenomenon as the “digital economy” has arisen and is developing. The task of the modern state is to create digital services and platforms aimed at more rapid and high-quality satisfaction of the needs of citizens and business, that is, in essence —to generate a new type of public goods in the form of digital public services. The article considers the prospects for the development of such processes.

Published: May 2022

Aim: This study was conducted to assess the mitigation effect of A. vera leaf ethanolic and water extracts on plant growth, MDA and protein content, and mitotic index of barley seedlings irrigated with sewage water. Methodology: The experiment was conducted in a green house in Al-Ahsa, Saudi Arabia, in plastic bags containing air-dried loam soil and compost (1:1). Wastewater samples were collected from Al-Ahsa Sewage Treatment Plant/Al-Ahsa/Saudi Arabia. Seeds of barley were exposed to the following treatments for three weeks: 100% treated wastewater, treated wastewater mixed with: 0.05 g ml-1 A. vera alcoholic extract (Alc Ext) or 0.05 g ml-1 A. vera water extract (Wat Ext), 0.15 g ml-1 Alc Ext or 0.15 g ml-1 Wat Ext. Similar test doses were prepared for untreated wastewater. A separate set of seeds was prepared using distilled water as a control. Germination rate, fresh and dry weight, protein content, MDA content and mitotic index were determined. Results: Untreated wastewater caused significant reduction in fresh weight while both treated and untreated wastewater showed insignificant decrease in dry weight of barley. No significant change in MDA contents were observed in all treatments, except for addition of 0.15 A. vera water extract to untreated wastewater. Protein content showed an increase in both treated wastewater (insignificant) and untreated wastewater (significant). Addition of A. vera extracts increased accumulation of protein in both shoot and root. A. vera alcoholic extract promoted significant increase in both root and shoot protein of treated wastewater, but only shoot protein of untreated wastewater. A significant reduction in mitotic index was induced by wastewater, while addition of A. vera extracts stimulated significant increase in mitotic index. Interpretation: A. vera possess reactive oxygen species scavenging ability and enzyme conservation activity in addition to stimulatory effects on cell proliferation and cell-cycle process that add a modulation credit on protein content and mitotic index of barley.

Aim: To evaluate the efficiency of an integrated aquaculture system in a reservoir utilizing three components like ornamental fish, ornamental aquatic plant and leafy vegetable in floating net cages. Methodology: Components used in the study comprised Angelfish (Pterophyllum scalare), aquatic plant (Ceratophyllum demersum), and leafy vegetable (Spinacia oleracea). Angelfish and ornamental aquatic plants were stocked inside the net cages (3x3x3m), while leafy vegetables were grown on rafts floating on the surface of cages. Completely Randomized Design was followed in triplicates for 90 days. Three treatments T1, T2 and T3 were stocked with angelfish (0.24±0.06g) of varying stocking densities 20, 25, 30 m-3 respectively, along with uniform stocking densities of C. demersum (20 bundles per cage weighing 414.17±5.12 g per cage) and spinach (144 numbers per cage; average height 8.69±0.52 cm), whereas C1 (Angelfish 20/m3) and C2 (C. demersum and spinach) were used to compare the efficiency of the system. Results: The growth performances of angelfish after 90 days, in terms of average weight, survival rate, feed efficiency ratio and specific growth rate were significantly higher (p<0.05) in T3 with 1.60±0.09g, 87.04±0.98%, 0.32±0.001 and 2.11±0.01%/day respectively, whereas Feed Conversion Ratio was significantly lower (p<0.05) in T3 (3.15±0.01). There were no significant differences (p>0.05) in the biomass production of C. demersum and growth of spinach. Digestive and stress enzymes showed no significant difference (p>0.05) between the treatments and control. Interpretation: This study demonstrated the efficiency of the bio-integrated food production system paving a way to enhance the utilization of open water resources benefiting farmers with food and income.
Contemporizing island biogeography theory with anthropogenic drivers of species richness
Authors: Gleditsch Jason , Behm Jocelyn , Ellers Jacintha , Jesse Wendy , Helmus Matthew
Published: May 2022

Human activity has greatly accelerated in the past century impacting
biodiversity across the globe. To accurately explain contemporary
patterns of biodiversity, classic ecological theory must be updated to
incorporate the effects of this Great Acceleration on biodiversity. We
contemporized island biogeographic theory (IBT) and its extension, the
general dynamic model (GDM), to incorporate these effects. At their
core, IBT and GDM predict positive relationships between island species
richness and habitat diversity, and negative relationships between
island species richness and isolation from source pools of species.
Through the Great Acceleration, land development on islands has altered
habitat diversity and the introduction of species through global trade
has reduced island isolation. We contemporize IBT and GDM by
conceptualizing trajectories of how species richness on islands will
change given accelerations to land development and trade. Considering
these contemporary trajectories, we provide expectations for the
relationships of native, introduced, and total species richness with
natural and anthropogenic metrics of habitat diversity (geographic and
economic area, respectively) and isolation from source pools (geographic
and economic isolation, respectively). We assessed the expectations
across reptile and amphibian clades of the Caribbean islands. As
expected by the contemporized theory, natural habitat diversity metrics
exhibited positive relationships with both native and introduced species
richness, strengthening total species richness-area relationships.
Geographic isolation exhibited negative relationships with native and
positive relationships with introduced species richness, weakening total
species richness-isolation relationships. Economic area and isolation
both exhibited negative relationships with native richness, but positive
and negative relationships, respectively, with introduced richness.
Total species richness relationships with economic area and isolation
were also strongest in clades with many introduced species. As more
species spread globally, the contemporary expectations we articulate
here will increasingly predict island biogeography of the Anthropocene.
