Background

Healthcare workers are disproportionately affected by COVID-19. In low- and middle- income countries, they may be particularly impacted by underfunded health systems, lack of personal protective equipment, challenging working conditions and barriers in accessing personal healthcare.

Methods

In this cross-sectional study, occupational health screening was implemented at the largest public sector medical centre in Harare, Zimbabwe, during the “first wave” of the country’s COVID-19 epidemic. Clients were voluntarily screened for symptoms of COVID-19, and if present, offered a SARS-CoV-2 nucleic acid detection assay. In addition, measurement of height, weight, blood pressure and HbA1c, HIV and TB testing, and mental health screening using the Shona Symptom Questionnaire (SSQ-14) were offered. An interviewer-administered questionnaire ascertained client knowledge and experiences related to COVID-19.

Results

Between 27th July and 30th October 2020, 951 healthcare workers accessed the service; 210 (22%) were tested for SARS-CoV-2, of whom 12 (5.7%) tested positive. Clients reported high levels of concern about COVID-19 which declined with time, and faced barriers including lack of resources for infection prevention and control.

There was a high prevalence of largely undiagnosed non-communicable disease: 61% were overweight or obese, 34% had a blood pressure of 140/90mmHg or above, 10% had an HbA1c diagnostic of diabetes, and 7% had an SSQ-14 score consistent with a common mental disorder. Overall 8% were HIV-positive, with 97% previously diagnosed and on treatment.

Conclusions

Cases of SARS-CoV-2 in healthcare workers mirrored the national epidemic curve. Implementation of comprehensive occupational health services during a pandemic was feasible, and uptake was high. Other comorbidities were highly prevalent, which may be risk factors for severe COVID-19 but are also important independent causes of morbidity and mortality. Healthcare workers are critical to combatting COVID-19; it is essential to support their physical and psychological wellbeing during the pandemic and beyond.

Published: November 2021

Biomass and carbon (C) distribution are suggested as strategies of plant responses to resource stress. Understanding the distribution patterns of biomass and C is the key to vegetation restoration in fragile ecosystems, however, there is limited understanding of the intraspecific biomass and C distributions of shrubs resulting from plant interactions in karst areas. In this study, three vegetation restoration types, aDodonaea viscosamonoculture (DM), aEucalyptus maideniandD.viscosamixed-species plantation (EDP) and aPinus massonianaandD.viscosamixed-species plantation (PDP), were selected to determine the effects of plant interactions on the variations in the C distributions ofD.viscosaamong the three vegetation restoration types following 7 years of restoration. The results showed that: (1) plant interactions decreased the leaf biomass fraction. The interaction ofP.massonianaandD.viscosadecreased the branch biomass fraction and increased the stem and root biomass fraction, but not the interaction ofE.maideniandD.viscosa. Plant interactions changed the C concentrations of stems and roots rather than those of leaves and branches. (2) Plant interactions affected the soil nutrients and forest characteristics significantly. Meanwhile, the biomass distribution was affected by soil total nitrogen, clumping index and gap fraction; the C concentrations were influenced by the leaf area index and soil total phosphorus. (3) The C storage proportions of all the components correlated significantly with the proportion of biomass. Our results suggested that both the biomass distribution and C concentration ofD.viscosawere affected by plant interactions, however, the biomass fraction not the C concentration determines the C storage fraction characteristics forD.viscosa.
Sensitivity analysis of a reduced model of thrombosis under flow: Roles of Factor IX, Factor XI, and γ‘-Fibrin
Authors: Chen Jason , Diamond Scott L.
Published: November 2021

A highly reduced extrinsic pathway coagulation model (8 ODEs) under flow considered a thin 15-micron platelet layer where transport limitations were largely negligible (except for fibrinogen) and where cofactors (FVIIa, FV, FVIII) were not rate-limiting. By including thrombin feedback activation of FXI and the antithrombin-I activities of fibrin, the model accurately simulated measured fibrin formation and thrombin fluxes. Using this reduced model, we conducted 10,000 Monte Carlo (MC) simulations for ±50% variation of 5 plasma zymogens and 2 fibrin binding sites for thrombin. A sensitivity analysis of zymogen concentrations indicated that FIX activity most influenced thrombin generation, a result expected from hemophilia A and B. Averaging all MC simulations confirmed both the mean and standard deviation of measured fibrin generation on 1 tissue factor (TF) molecule per μm2. Across all simulations, free thrombin in the layer ranged from 20 to 300 nM (mean: 50 nM). The top 2% of simulations that produced maximal fibrin were dominated by conditions with low antithrombin-I activity (decreased weak and strong sites) and high FIX concentration. In contrast, the bottom 2% of simulations that produced minimal fibrin were dominated by low FIX and FX. The percent reduction of fibrin by an ideal FXIa inhibitor (FXI = 0) ranged from 71% fibrin reduction in the top 2% of MC simulations to only 34% fibrin reduction in the bottom 2% of MC simulations. Thus, the antithrombotic potency of FXIa inhibitors may vary depending on normal ranges of zymogen concentrations. This reduced model allowed efficient multivariable sensitivity analysis.

Published: November 2021

Background

In recent non-pandemic periods, tuberculosis (TB) has been the leading killer worldwide from a single infectious disease. Patients with DM are three times more likely to develop active TB and poor treatment outcomes. Single glycemic measurements at TB diagnosis may inaccurately diagnose or mischaracterize DM severity. Data are limited regarding glycemic dynamics from TB diagnosis through treatment.

Methods

Prospective study of glycemia dynamics in response to TB treatment measured glycosylated haemoglobin (HbA1c) in patients presenting to TB screening centres in Bangladesh to determine the prevalence and risk factors of hyperglycemia before and at TB treatment completion.

Results

429 adults with active TB disease were enrolled and divided into groups based on history of DM and initial HbA1c range: normoglycemia, prediabetes, and DM. DM was diagnosed in 37%. At treatment completion,14(6%) patients from the normoglycemia and prediabetes groups had HbA1c>6.5%, thus increasing the prevalence of DM to 39%. The number needed to screen to diagnose one new case of DM at TB diagnosis was 5.7 and 16 at treatment completion in the groups without DM. Weight gain>5% at treatment completion significantly increased the risk of hyperglycemia in the groups without DM at TB diagnosis (95% CI 1.23–26.04, p<0.05).

Conclusion

HbA1c testing prior to and at TB treatment completion found a high prevalence of prediabetes and DM, including a proportion found at treatment completion and commonly in people with a higher percentage of weight gain. Further longitudinal research is needed to understand the effects of TB disease and treatment on insulin resistance and DM complications.
Changes in choroidal vascular structure from vitreoretinal lymphoma and the intraocular cytokine level associated with clinical resolution after intravitreal methotrexate treatment
Authors: Kim Rae-Young , Park Jae Hyun , Kim Mirinae , Park Young-Geun , Cho Seok-Goo , Park Young-Hoon
Published: November 2021

Purpose

To evaluate changes in choroidal vascular structure and aqueous cytokine levels in eyes with vitreoretinal lymphoma (VRL) after intravitreal methotrexate (MTX) treatment.

Methods

In this retrospective study, VRL patients who visited our hospital between October 2018 and July 2020 were reviewed. Aqueous samples were obtained before treatment and at clinical resolution after intravitreal MTX therapy. Interleukin (IL)-6 and IL-10 levels and the IL-10-to-IL-6 ratio were evaluated. Swept-source optical coherence tomographic images were obtained along with the aqueous samples. Subfoveal choroidal thickness (SFCT), total vascular area of the choroid (TCA), stromal area (SA), luminal area (LA), and choroidal vascularity index (CVI) were assessed.

Results

Twelve patients were enrolled (female:male—5:7). The mean age (± standard deviation) at diagnosis was 60.9±8.5 years. In the 16 eyes diagnosed with VRL, values of SFCT, TCA, LA, and SA significantly decreased after treatment (all p-values <0.05). Additionally, the aqueous cytokine IL-10 level and IL-10-to-IL-6 ratio were significantly decreased (p = 0.001 and p = 0.003, respectively). The choroidal structure in the non-treated fellow eyes did not show any significant difference. There were no further changes in SFCT, TCA, LA, or CVI that occurred during maintenance therapy. For clinical remission, the patients received 7.7±5.5 intravitreal MTX injections. The required number of injections for clinical remission was positively correlated with best-corrected visual acuity, IL-10, and IL-6 levels in the active phase (p = 0.035, p = 0.009, and p = 0.031, respectively).

Conclusion

Eyes with active VRL exhibited choroidal thickening with increased vascular and stromal areas that decreased after remission following MTX treatment. Higher aqueous IL-10 and IL-6 levels and lower visual acuity in the active phase may indicate the number of injections required for remission; this should be considered in the treatment of patients with VRL.

Published: November 2021

Background

Delays in patient flow and a shortage of hospital beds are commonplace in hospitals during periods of increased infection incidence, such as seasonal influenza and the COVID-19 pandemic. The objective of this study was to develop and evaluate the efficacy of machine learning methods at identifying and ranking the real-time readiness of individual patients for discharge, with the goal of improving patient flow within hospitals during periods of crisis.

Methods and performance

Electronic Health Record data from Oxford University Hospitals was used to train independent models to classify and rank patients’ real-time readiness for discharge within 24 hours, for patient subsets according to the nature of their admission (planned or emergency) and the number of days elapsed since their admission. A strategy for the use of the models’ inference is proposed, by which the model makes predictions for all patients in hospital and ranks them in order of likelihood of discharge within the following 24 hours. The 20% of patients with the highest ranking are considered as candidates for discharge and would therefore expect to have a further screening by a clinician to confirm whether they are ready for discharge or not. Performance was evaluated in terms of positive predictive value (PPV), i.e., the proportion of these patients who would have been correctly deemed as ‘ready for discharge’ after having the second screening by a clinician. Performance was high for patients on their first day of admission (PPV = 0.96/0.94 for planned/emergency patients respectively) but dropped for patients further into a longer admission (PPV = 0.66/0.71 for planned/emergency patients still in hospital after 7 days).

Conclusion

We demonstrate the efficacy of machine learning methods at making operationally focused, next-day discharge readiness predictions for all individual patients in hospital at any given moment and propose a strategy for their use within a decision-support tool during crisis periods.
Predictors of return to work among women with long-term neck/shoulder and/or back pain: A 1-year prospective study
Authors: Rashid Mamunur , Kristofferzon Marja-Leena , Nilsson Annika
Published: November 2021

Background

Sick leave due to musculoskeletal pain, particularly in the neck/shoulders and back, is one of the major public health problems in Western countries such as Sweden. The aim of this study was to identify predictors of return to work (RTW) among women on sick leave due to long-term neck/shoulder and/or back pain.

Methods

This was a prospective cohort study with a 1-year follow-up. The study participants were recruited from a local Swedish Social Insurance Agency register and had all been on sick leave for ≥ 1 month due to long-term (≥ 3 months) neck/shoulder and/or back pain. Data on predictors and outcome were collected using a self-administered questionnaire. A total of 208 women aged 23–64 years were included at baseline, and 141 responded at the 1-year follow-up. Cluster analyses were performed to identify one predictor from each cluster for use in the regression model.

Results

At the 1-year follow-up, 94 of the 141 women had RTW and 47 had not. Women who engaged in more coping through increasing behavioral activities (OR: 1.14, 95% CI: 1.03–1.25) and those who more strongly believed they would return to the same work within 6 months (OR: 1.22, 95% CI: 1.10–1.37) had an increased probability of RTW. Receiving more social support outside work (OR: 0.50, 95% CI: 0.28–0.92) decreased the odds of RTW at the 1-year follow-up.

Conclusions

Behavioral activities, beliefs about returning to the same work, and social support outside work were predictors of RTW at the 1-year follow-up. Healthcare professionals should consider these predictors in their efforts to prevent prolonged sick leave and to promote RTW in this population.
Academics Perceptions of Electronic Resources at the University of Venda, South Africa
Authors: Ndou Alugumi Samuel , Chilimo Wanyenda Leonard
Published: November 2021

This study examined the perceptions of academic researchers regarding electronic resources (e-resources) provided by the library at the University of Venda (UNIVEN), South Africa. The quantitative research approach and survey research design were adopted to conduct the investigation. Data was collected using a self-administered structured questionnaire randomly distributed to 45 UNIVEN academics. The findings of this study revealed that although academics at UNIVEN find e-resources easy to use, believe the resources improve academic performance, and frequently encouraged postgraduate students to use them, the majority of them had plagiarism concerns and were only moderately satisfied with available e-resources at UNIVEN. This study recommends that the university library should train academics on plagiarism detection. In addition, the library should adopt innovative ways of improving e-resource services, such as providing an Online Public Access Catalogue (OPAC) with advanced and federated search capabilities.

D1/D5 Dopamine Receptors and mGluR5 Jointly Enable Non-Hebbian Long-Term Potentiation at Sensory Synapses onto Lamina I Spinoparabrachial Neurons
Authors: Li Jie , Price Theodore J. , Baccei Mark L.
Published: November 2021

Highly correlated firing of primary afferent inputs and lamina I projection neurons evokes synaptic long-term potentiation (LTP), a mechanism by which ascending nociceptive transmission can be amplified at the level of the spinal dorsal horn. However, the degree to which neuromodulatory signaling shapes the temporal window governing spike-timing-dependent plasticity (STDP) at sensory synapses onto projection neurons remains unclear. The present study demonstrates that activation of spinal D1/D5 dopamine receptors (D1/D5Rs) creates a highly permissive environment for the production of LTP in male and female adult mouse spinoparabrachial neurons by promoting non-Hebbian plasticity. Bath application of the mixed D1/D5R agonist SKF82958 unmasked LTP at STDP pairing intervals that normally fail to alter synaptic efficacy. Furthermore, during D1/D5R signaling, action potential discharge in projection neurons became dispensable for LTP generation, and primary afferent stimulation alone was sufficient to induce strengthening of sensory synapses. This non-Hebbian LTP was blocked by the D1/D5R antagonist SCH 39166 or genetic deletion of D5R, and required activation of mGluR5 and intracellular Ca2+release but was independent of NMDAR activation. D1/D5R-enabled non-Hebbian plasticity was observed across multiple neuronal subpopulations in the superficial dorsal horn but was more prevalent in spinoparabrachial neurons than interneurons. Interestingly, the ability of neonatal tissue damage to promote non-Hebbian LTP in adult projection neurons was not observed in D5R knock-out mice. Collectively, these findings suggest that joint spinal D1/D5R and mGluR5 activation can allow unfettered potentiation of sensory synapses onto the output neurons responsible for conveying pain and itch information to the brain.

SIGNIFICANCE STATEMENTSynaptic LTP in spinal projection neurons has been implicated in the generation of chronic pain. Under normal conditions, plasticity at sensory synapses onto adult mouse spinoparabrachial neurons follows strict Hebbian learning rules, requiring coincident presynaptic and postsynaptic firing. Here, we demonstrate that the activation of spinal D1/D5Rs promotes a switch from Hebbian to non-Hebbian LTP so that primary afferent stimulation alone is sufficient to evoke LTP in the absence of action potential discharge in projection neurons, which required joint activation of mGluR5 and intracellular Ca2+release but not NMDARs. These results suggest that D1/D5Rs cooperate with mGluR5 receptors in the spinal dorsal horn to powerfully influence the amplification of ascending nociceptive transmission to the brain.
A encarnação monstruosa

Este artigo examina como a figuração do humano no cinema articula e tensiona as noções de carne, corpo, identidade, personagem, figura e imagem. Recorreremos ao monstro como uma figura que tanto explicita quanto perturba o funcionamento habitual da figuração, revelando cisões entre corpos e identidades e desinventando o corpo de modo a explicitar a realidade da carne. Para tanto, investigaremos, em particular, os conceitos de “figura” e de “carne”, que serão mobilizados na análise de três filmes de horror que colocam em jogo uma mesma sensação do infamiliar: Vampiros de almas (Don Siegel, 1956), O enigma de outro mundo (John Carpenter, 1982) e Corrente do mal (David Robert Mitchell, 2014).
Social justice in education from the perspective of the Roma in the Czech Republic – A case study
Authors: Levínská Markéta , Bittnerová Dana
Published: November 2021

This paper addresses the current educational rights of the Roma community (in the Czech Republic). The aim of the paper is to present the educational system, its advantages and disadvantages and the ways in which the legal system supports educational rights. The second part of the paper focuses on the exercising and negotiation of rights in the contemporary social context. The work is based on ethnographic research conducted since 2005 by the Levínská, Bittnerová, & Doubek team in socially excluded localities. The data analysis is based on the theoretical concept of cognitive anthropology and the cultural models theory (D’Andrare, & Strauss, 1992). Cultural models and the ways in which parents, students and teachers negotiate rights are presented. The tension between rationality and morality (Bateson, 1958) is demonstrated by the models’ endurance; communication, cognitive and material support; and independence. Although the system itself provides equal opportunities, the prospects that education affords are a fundamental problem. One obstacle is racial bias, which influences members of the dominant group. Another significant obstacle is poverty and the costs of higher education, which are beyond the financial capacity of poor families. A third obstacle is knowledge, which is insufficient in excluded localities and poor families, and that families are unable to give students adequate support in navigating the full scope of student responsibilities.

Three new species of Calathea (Marantaceae) endemic to Colombia
Authors: Kennedy Helen
Published: November 2021

Calathea neurophylla H. Kenn., C. barryi H. Kenn., and C. velutinifolia H. Kenn., endemic to Colombia, are described as new. Calathea neurophylla is characterized by the single cauline leaf subtending one or more inflorescences of spirally arranged bracts and the markedly ridged, narrowly elliptic leaf blades (length 6.25–8.46 times width). Calathea barryi is characterized by the single cauline leaf subtending several inflorescences with 25–43 spirally arranged bracts and the very closely spaced lateral veins (ca. 67 per 3 cm). Calathea velutinifolia is distinguished by the 4–15 basal leaves, the densely appressed velvety tomentose adaxial the leaf surface and the 8–10 distichous, white bracts.
Novelties in neotropical Dilleniaceae
Authors: Aymard C. Gerardo A.
Published: November 2021

A new species of Doliocarpus (Dilleniaceae), Doliocarpus putumayensis Aymard from the Porvenir River (affluent of the lower Putumayo River), and the middle Caquetá River in the state of Amazonas was found during the examination of specimens for the Dilleniaceae treatment for the Flora de Colombia. This species is not clearly related to any other Doliocarpus species, however, it shows certain similarities with D. magnificus Sleumer in its leaves size, shape, and the fruit size and pubescence. Nonetheless, P. putumayensis differs in its tertiary venation, inflorescence size, sepal number and shape, anthers glabrous with a connective broadened, and fruit densely adpressed pubescent. An updated key to the species of Doliocarpus of Colombia is provided, and a previously described subspecies from Brazil is elevated to the rank of species (i.e., Doliocarpus brevipedicellatus Garcke subsp. hilarianus Kubitzki to D. hilarianus Aymard).
Additions to the vascular flora of Costa Rica: four new records from the Sabanas Miravalles
Authors: Jiménez José Esteban
Published: November 2021

The Costa Rican vascular flora is well known and studied, but there are gaps of floristic knowledge in some areas and ecosystems that are poorly explored. The Costa Rican savannas, cover a small geographic extent and are almost unexplored floristically. The Sabanas Miravalles are located in the western flank of the Volcán Miravalles in the Cordillera de Guanacaste. As a result of a broad floristic inventory of this site, four species have been documented as new records for the Costa Rican vascular flora: Eriocaulon fuliginosum, Polygala pseudocoelosioides, Trimezia martinicensis, and Utricularia subulata.

As part of ongoing efforts to understand and document the flora of the southeastern United States, a number of taxonomic changes at generic, specific, and infraspecific rank are made. We also discuss and clarify the recommended taxonomy for other taxa (not requiring nomenclatural acts) and present a point of view about the practical and philosophic basis for making taxonomic changes in an allegedly well-understood flora. The genera (and families) affected are Allium (Alliaceae), Erigeron, Liatris, and Trilisa (Asteraceae), Calycanthus (Calycanthaceae), Gaylussacia (Ericaceae), Dalea and Mimosa (Fabaceae), Hydrophyllum (Hydrophyllaceae), Didymoglossum (Hymenophyllaceae), Monarda (Lamiaceae), Kosteletzkya and Sida (Malvaceae), Narthecium (Nartheciaceae), Agalinis, Melampyrum, and Orobanche/Aphyllon/Myzorrhiza (Orobanchaceae), Dichanthelium and Elymus (Poaceae), Clematis (Ranunculaceae), and Maianthemum (Ruscaceae).
Morphology corroborates DNA sequence data in the species-level recognition of Gaultheria trichophylla var. tetracme (Ericaceae)
Authors: Fritsch Peter W. , Lu Lu , Zhang Ming-Ying , Wang Hong , Li De-Zhu
Published: November 2021

Gaultheria trichophylla var. tetracme of G. series Trichophyllae (Ericaceae) has been distinguished from the nominate variety of G. trichophylla by the presence of two awns on each anther theca (versus one). Phylogenetic data based on plastid DNA sequences placed G. t. var. tetracme in a different clade than the nominate variety with strong statistical support, suggesting that G. trichophylla is not monophyletic. To investigate this further, we studied the morphology of these two taxa in the field and with herbarium material. We found that G. t. var. tetracme differs substantially from the nominate variety in morphology, not only by the number of anther awns, but also the larger size of many features, e.g., plant height, leaves, and pedicels, a greater number of leaf marginal setae, and a distinct geographic range. On this basis, we elevate G. t. var. tetracme to the species level as Gaultheria tetracme, endemic to the Hengduan Shan in Sichuan Province, China. We note the wide morphological variation in the remainder of G. trichophylla and indicate specific problems that should be investigated in more detail for better understanding the taxonomy of this species.
An annotated vascular flora and floristic analysis of the southern half of the Nature Conservancy Davis Mountains Preserve, Jeff Davis County, Texas, U.S.A.
Authors: Keeling Jeffrey James
Published: November 2021

The Nature Conservancy Davis Mountains Preserve (DMP) is located 40 km northwest of Fort Davis, Texas, in the northeastern region of the Chihuahuan Desert and consists of some of the most complex topography of the Davis Mountains, including their summit, Mount Livermore, at 8378 ft (2554 m). The cool, temperate, "sky island" ecosystem caters to the requirements that are needed to accommodate a wide range of unique diversity, endemism, and vegetation patterns, including desert grasslands and montane savannahs. The current study began in May of 2011 and aimed to catalogue the entire vascular flora of the 18,360 acres of Nature Conservancy property south of Highway 118 and directly surrounding Mount Livermore. Previous botanical investigations are presented, as well as biogeographic relationships of the flora. The numbers from herbaria searches and from the recent field collections combine to a total of 2,153 voucher specimens, representing 483 species and infraspecies, 287 genera, and 87 families. The best-represented families are Asteraceae (89 species, 18.4% of the total flora), Poaceae (76 species, 15.7% of the total flora), and Fabaceae (21 species, 4.3% of the total flora). The current study represents a 25.44% increase in vouchered specimens and a 9.7% increase in known species from the study area’s 18,360 acres and describes four endemic and fourteen non-native species (four invasive) on the property. The subsequent analysis of the results, compared to those of previous regional-flora catalogues, presents the flora of the DMP as one that is unique to the higher elevations and igneous substrates of western Texas and the northern Chihuahuan Desert. Multiple influences from overlapping and neighboring ecoregions, including the Great Plains, Madrean, and Sonoran provinces, are all seen to have varying degrees of authority in regards to the shaping of the modern-day vegetation.

Background: The COVID-19 pandemic is a major concern. However, its association and rising cases of mucormycosis, also known as black fungus make the scenario even more troublesome. In addition, no specific medication against mucormycosis/black fungus makes things even worse. Objective: Garlic phytoconstituents have shown remarkable antifungal properties against various fungal species in various studies. Thus, the objective of the study was to check the potency of garlic phytoconstituents against the 1,3-beta-glucan synthase fungal protein using in-silico methods. Method: Auto Dock was used to evaluate selected garlic phytochemical molecules against 1,3-beta-glucan synthase fungal protein, and Discovery studio visualizer was used to create 3D and 2D interaction photos. Results: Five out of 9 phytoconstituents were found to form conventional hydrogen bonds, and only alliin formed the highest number of hydrogen bonds. However, the binding energy and inhibition constant of all nine phytoconstituents were determined. Interestingly, Z-ajoene showed the lowest binding energy of -5.07 kcal/mol and inhibition constant of 192.57µM. Conclusion: The results of our investigation suggested that garlic phytochemicals can have a good impact against black fungi, pertaining to the significant binding energies of phytoconstituents during blind docking. Specifically, Z-ajoene could be a good alternate against black fungi. However, detailed research is required to explore the antifungal activity of garlic against mucormycosis.
Assessing Storage Insect Pest infestations and Faecal dropping of Rodent in Stored Grains from two districts of Southwestern Ethiopia
Authors: Marid Tadesse , Md Jamshed Ali
Published: November 2021

This study was designed to assess the occurrence of major insects and rodent pest infestations in stored grain from two districts of Southwestern Ethiopia. Omo Nada and Bako Tibe districts were purposively selected because they are potential maize and sorghum growing regions with high postharvest losses. A total of 160 farmers’ stores from both the districts were randomly selected. The grain samples used in the present study were stored for five different time periods, ranging from 1 to 5 months and from the same farmers’ stores, to identify storage insect pest, determine grain weight loss and insect damage. The results showed that the dominant insect species in maize and sorghum grains were weevils (Sitophilus spp.) followed by the Angoumois gelechiid (Sitotroga cerealella Olivier) and flour beetles (Tribolium spp.). High number of insects were recorded from both plastered and un-plastered gombisa and polypropylene bags. Additionally, the amount of every insect pest in each storage container recorded per 100 g grain increased because the duration of grain storage increased. There have been 0.33-1.29g and 0.44-1g of rodent droppings per 100g sample of maize and sorghum grains, respectively. This showed that faecal dropping per 100 g grain increased along with increase in storage period. Grain damage showed significant (P<0.05) differences over the storage periods across the studied districts. A similar trend was observed for weight loss in each of the grains all districts. These results indicated that farmers are incurring a substantial grain loss to insects and rodent pests. Hence, there is an urgent need to devise appropriate tactics for protecting the losses in farm-stored maize and sorghum in Ethiopia.

Evaluation of entomopathogenic fungi by larval and adult immersion method v1
Authors: Torres-Torres Lissette , Espinel-Correal Carlos , Santos-Díaz Adriana
Published: November 2021

The search for commercially viable entomopathogenic fungi for use in integrated pest management programs involves several steps. Fungal species must first be obtained from diseased insects or the environment and identified. Then, they must be evaluated under laboratory conditions to identify the most promising candidates. Because of that, bioassays must be repeatable and reliable to determine accurate pathogenicity or virulence. Variability in results may be caused by the variation in the components of an assay. However, the availability of a standardized bioassay is limited. Few reports detail the methods used to develop bioassays for a specific purpose and, without these details, it is difficult to develop bioassay methodologies suitable to evaluate the fungus-host relationship. We described a protocol based on the immersion method to evaluate entomopathogenic fungi (larval and adult stages), that can be reproduced to reduce variability. This protocol can be used in several stages of biopesticide development: selection of the biological control agent, characterization of the microorganism, formulation compatibility, and in vitro evaluation of efficacy.

Gelatin as a hemostatic agent
Authors: Carnot P.
Published: November 2021

The property of gelatine to coagulate blood is specified in 1896 by Dastre and Floresco. The resulting gelatinous blood coagulation is able to organize itself quickly. The author, together with Cornil, experienced the nutritious and absorbent properties of gelatine and other protein substances (by marking pieces of sponge wetted in these substances, in the abdomen of dogs and observing the growth of these pieces) and came to the conclusion that gelatine takes precedence in this respect.

State of the system of immunobiological control is of great importance for pathogenesis of uterine myoma as of any process of tumorous growth.

56 patients were examined to study their clinical and laboratory data, total serum interferon, the ability of peripheral blood leucocytes to synthesize a/b- and g -interferons, cytotoxic activity of natural killer cells.

The ability of peripheral blood leucocytes to synthesize a/b -interferon was found to be low in 89,5% of patients, g -interferon - in 51,6%. In women with very low g -interferon level (max 28, min 14) the size of myomatic nodes exceeded 5 cm in diameter, fast growth of tumors was noted. Cytotoxic activity of natural killers was low in 27% of women, and all of them had either fast growth of the uterine myoma (with nodes more than 5 cm in diameter) or myoma recurrence after myomectomy.

High positive correlation was found between the patients age and the ability of peripheral blood leucocytes to produce g -interferon (correlation coefficient = 0,44), between the size of a myomatic node and indices of the functional activity of natural killers (c.c. = 0,35), between the ability of peripheral blood leucocytes to produce a/b -interferon and functional activity of natural killer cells (c.C. 0,32).

So, the growth of uterine myoma can be predicted indirectly by the showings of cytotoxic activity of natural killer cells and by the ability of peripheral blood leucocytes to produce g-interferon.

Authors:   Dar Al Hekma University, Jeddah, KSA, Itani Malakeh M. , Sinno Manal K.
Published: November 2021

Knowing that the teaching-learning experience has recently shifted to online platforms, researchers are concerned about enhancing students' motivation. This study aims at finding the relationship between teachers' ICT knowledge and students' motivation in online learning. A sample of 169 students enrolled at a private university in Jeddah, KSA, answered a survey of eight questions explicitly constructed for this research. Structured interviews with sixteen students and four teachers of different majors were conducted to triangulate the data. Descriptive statistics for each variable were then calculated. The results indicated that the factor that motivates the students most is the teacher's skillful use of online tools such as Announcements, Journal, Discussion Board, and Wiki. On the other hand, the factor that has the lowest effect on students' motivation is the teacher's ability to solve technical problems that emerge in online classes. Teachers' ICT knowledge is found to be directly related to students' motivation in online classes. It is, therefore, recommended that teachers have an adequate practice of using ICT in their online classes.
