Published: October 2022

Abstract

The impacts from urban areas may result in alterations in environmental characteristics and wild populations dynamics. Therefore, we aimed at assessing population size, density, home range, maximum range of movement and habitat selection of native and aliens freshwater turtles in a Brazilian urban park (Phrynops geoffroanus-PG, Trachemys dorbigni-TD, Trachemys scripta elegans-TSE). We applied capture-mark-recapture procedures from July/2016 to August/2018. Home ranges were estimated from trap locations using a 100% minimum convex polygon (MCP) method, and habitat selections using eigenanalysis. We sampled 41 PG, 35 TD, and 20 TSE. Population size was estimated as 59 ± 7.6 (PG), 36 ± 1.4 (TD), and 20 ± 0.5 (TSE) individuals (± SE), with a density estimates of 1.36 (0.34), 1.72 (0.36), and 0.87 (0.25) individual/ha (± SE), respectively. Home ranges size ranged between 0.04 ha and 0.48 ha, the highest distance was reached by D'Orbigny's slider (525.8 m). Our results indicate that habitat preferred for all species is clearly influenced by human presence, and the turtle assemblage exhibit strategies as temporal segregation to coexist on this small, closed park. Both the presence of two established populations of invasive alien species and the changing movement of freshwater turtles reflect anthropic pressure on wild population dynamics and the lack of effectiveness of environmental policies and inspection in Brazil. The understanding that wild populations are being affected even in conservation units could be considered by the managers implement monitoring of target wild populations, control of exotic species, insertion of educational signs and actions, and control of visitors.

Abstract

This is because text mining can reduce the time invested in pre-contextual research on coal mine safety in China. Therefore, this paper uses a combined BiLSTM-CRF model to handle the recognition of data. The optimal number of topics for LDA is determined by combining the perplexity and the topic variance, and this is done by manually annotating the coal mine safety corpus with the BIO annotation method. The BiLSTM-CRF combined model was then used to initially split the data into words and manually correct them. The combined BiLSTM-CRF model was repeatedly trained until the combined model met the word separation requirements. Finally, the LDA model was used to mine the data for topics. The results show that the combined BiLSTM-CRF model is able to recognise long proper nouns and achieve recognition in both English and Chinese. The combination of confusion and topic variance to determine the optimal number of topics for LDA can provide a reference for manual determination of the optimal number of topics for LDA.

Published: October 2022

Abstract
Background: Alcohol consumption during pregnancy is a significant public health and pregnancy-related problem, such as spontaneous abortion, stillbirth or low birth weight. According to the WHO, there is no safe amount of alcohol consumption during pregnancy. Studies show high rates of alcohol consumption during pregnancy in sub-Saharan African countries with a prevalence range (2.2-87%). This research aimed to determine the prevalence and factors associated with alcohol consumption among pregnant women attending antenatal care in a rural district of Tete, Mozambique. Methods: A cross sectional survey was conducted between May and June 2022. The non-probability convenience method was applied for sample selection. Prevalence was determined using a 95% CI. binary logistic Regression was used to determine the factors associated with alcohol consumption. Data were analysed using statistical SPPS v26 and Stata.
Results: a total of 177 pregnant women participated in the survey. The prevalence of alcohol consumption during pregnancy was 85.9% (152/177; 95% CI: 80.7-91.0), which was associated with increasing age (OR= 8.86; 95% CI: 2.646-29.687; p-value = 0.00 and OR= 9.81; 95% CI: 2.262-42.576; p-value = 0.002) respectively. In addition, another associated factor was following some religion (OR= 0.07; 95% CI: 0.020-0.246; p-value = 0.00).
Conclusion: The survey significantly reveals a high prevalence of alcohol consumption among pregnant women attended in a antenatal care in Chitima. Maternal age and religion were the variables that have some significant association with alcohol consumption during pregnancy. Therefore, interventions for behavioural change to reduce alcohol consumption during pregnancy are needed, especially in all age groups.

Published: October 2022

Abstract
Robotic grasping has been widely used in various industries. How to meet the requirements of grasping accuracy and grasping speed at the same time is a challenging problem in real-time grasping tasks. In this paper, aiming at the real-time grasping task in retail warehousing, a lightweight grasping pose estimation model for retail warehousing is proposed. The model first uses the Focus module to perform lossless double downsampling, and learns each feature map of the upper layer through the dilated convolution block to expand the receptive field; then, the R-Resblock structure is improved to perform multi-scale feature fusion, and a lightweight RFB-SE module is designed to enrich feature information and reduce the number of parameters. Finally, after upsampling and restoring the image, the grasping quality, grasping angle, and grasping width of the target are regressed to obtain the optimal grasping pose of the target item. Experiments are carried out in the Cornell dataset, Jacquard dataset, and simulation environment respectively. The experimental results show that the method has a grasping accuracy of 97.8% and a grasping speed of 78FPS on the Cornell dataset. The success rate is 91.5%, and the grasping task in a retail warehouse environment is simulated in grasping simulation experiments.

Published: October 2022

Abstract
Background
Pre- and post-exposure prophylaxis (PrEP and PEP) haven’t been promoted among Chinese men who have sex with men (MSM) efficiently and nationally. As HIV prevalence among the population is high and increasing, it is urgent to facilitate PrEP and PEP promotion. This study aims to assess predictors for PrEP and PEP uptake and highlights for future promotion among MSM.
Methods
This cross-sectional study involved MSM in three large cities including Beijing, Shenzhen, and Kunming. We collected data by asking participants to scan a QR code with a cellphone and fill out an online questionnaire, which covers demographic and behavioral characteristics, and PrEP/PEP awareness and uptake. All participants provided online informed consent. The study protocol and informed consent form was approved by the institutional review board of National Center for AIDS/STD Control and Prevention.
Results
Between March and May 2019, the study enrolled 3,401 MSM. MSM being aware of, having consulted, and having taken PrEP and PEP accounted for 71.6%, 19.5%, 6.0%, 78.0%, 24.6%, and 11.4% respectively. Group sex and illicit drug use were associated with PrEP or PEP uptake. PrEP and PEP uptake was significantly associated with each other. MSM of 16-24 years old non-student were at higher risk of HIV infection and tested for HIV more frequently than other MSM, yet did not have higher PrEP/PEP uptake.
Conclusions
PrEP or PEP uptake was generally low among MSM in China. Integrating HIV testing, PrEP and PEP as an intervention package might facilitate PrEP/PEP uptake among the population. PrEP/PEP promotion should highlight MSM of 16-24 years old non-student.
Exploring midwifery competence and confidence based on midwives' experiences and stakeholders' insights in Kenya: A descriptive phenomenological approach
Authors: Tallam Edna , Kaura Doreen , Mash Robert 
Published: October 2022

Abstract

Background
Midwives who are educated and regulated to international standards can provide ninety percent of the needed essential care for women and newborns and reduce preventable maternal and child mortalities. However, inadequacies in midwifery care, especially in low- and middle-income countries, leads to lack of competence and confidence among midwives to achieve their potential.
The study objective was to explore midwives’ experiences and stakeholder insights into midwives’ competence and confidence in the four International Confederation of Midwives (ICM) domains; general competence, pre-pregnancy and antenatal care, labour and childbirth, and ongoing care of the woman and the baby.
Methods
A descriptive phenomenological study was utilised to explore these experiences. Ten midwives were purposively selected from subcounty, county and tertiary referral hospitals. Further, stakeholders (nine County Chief Nursing Officers and one Chief Executive Officer from the tertiary hospital in Kenya) were included. Interview guide questions were developed following the findings of the midwives’ self-perceived competence and confidence. All interviews were recorded, translated, and transcribed verbatim. Thematic analysis was done using the Colaizzi framework. Atlas. ti 9 software was utilised to assist with the coding categorisation and creating the themes.
Findings
Four themes emerged from the analysis. They included qualification categories, clinical practice experience, clinical practice environment and the need to optimise midwifery. In addition, multidisciplinary support and standardisation of midwifery practice were identified as key to promote the confidence and competence of midwives.
Conclusions
Midwives had disparities in competence and confidence during clinical practice, based on their different qualifications. A supportive environment emerged as necessary in enabling appropriate clinical experience, confidence, and competence. Standardisation of midwifery qualification promotes competence, which promotes the confidence of midwives in the clinical environment.

Published: October 2022

Abstract
Oral squamous cell carcinoma (OSCC) is one of the common oral cancers. This research is designed to establish a lipid metabolism-Immune-Based Prognostic Multiomics signature for OSCC and clarify the immune function, immune characteristics, the advantages of immune therapy, and pan-cancer analysis in the model-defined subgroups of OSCC. Based on lipid-metabolism-related genes and ESTIMATEScore, clustering analysis was applied to divide 373 OSCC samples into 21 high-immunity-lipid metabolism specimens and 172 low-immunity-lipid metabolism specimens. Through R packages “limma”, differential expression of mRNA, micro-RNA and DNA Methylation were identified. Then, the least absolute shrinkage and selection operator (LASSO) was applied to construct an 8-Multiomics Signature for predicting recurrence after surgery, and the risk model was validated in the TCGA-test and TCGA-train dataset. Afterward, the immune characteristics, immune function, and the advantages of ICI therapy in 8-Multiomics Signature subgroups were analyzed. Finally, the Pan-cancer analysis of eight symbols in the risk model was analyzed. In conclusion, 8-Multiomics Signature is a promising biomarker to distinguish the prognosis, the immune characteristics, and the immune benefit from immune therapy in OSCC.

Published: October 2022

Abstract
Purpose: During the past two years, in most institutions worldwide, educational activities were remodelled for remote delivery, due to the COVID-19 pandemic. The purpose of this study is to assess the effects of two-year distance learning on the physical activity and musculoskeletal health of university students.
Methods: This was a national, cross-sectional study using data collected via an online questionnaire distributed through university communication platforms, which included questions on online education routines, musculoskeletal health, and physical activity of university students.
Results: In total, 1366 students (65% female, 35% male) from 11 universities took part in the survey. The most common sites of reported pain were the neck (59.5%), shoulders (22.8%), back (29%), and low back (66.7%). Musculoskeletal pain was significantly increased during the lockdown, according to the VAS pain scale [Before: 2.7 (1.6); During: 5.5 (2.2), p<0.001). Everyday pain was referred by significantly more students during the lockdown (4.5% vs 36.1 %, p<0.001), while the percentage of asymptomatic students was significantly decreased (40.5% vs 6.1%, p<0.001). Concerning physical activity, the percentage of students who didn’t exercise significantly increased during the lockdown (15.1% vs 23.2%, p<0.001). Distance learning and total screen time were positively correlated with VAS pain scores. On the contrary, an increased frequency of ergonomic position, walking intervals, and physical activity was associated with significantly decreased VAS pain scores.
Conclusions: Distance learning and limited physical activity led to a significant increase in musculoskeletal pain of university students, while exercise and ergonomic body position were considered protective factors. Interventions to encourage physical activity and healthy studying habits should be developed by universities, since distance learning may be again necessary in the future.
The Discovery of Potential IGF1R Inhibitors: A Combination of Virtual Screening, Molecular Docking Studies, and in vitro/in vivo Biological Evaluation
Authors: Ruan Pinglang , Dai Pei , Mao Yu , Tang Zhongxiang , He Hanlin , Wu Guojun , Tan Yurong 
Published: October 2022

Abstract
Background
Insulin-like growth factor 1 receptor (IGF1R) is a newly discovered key receptor that allows RSV to enter cells. RSV and IGF1R fusion triggers PKCζ activation, promoting cell signaling by recruiting nucleolin from the nucleus to the plasma membrane. It is tempting to speculate that other pneumoviruses, including bovine RSV, bind to the IGF1R.
Methods
Natural products that are effective against IGF1R protein were screened from TargetMol drugs datas by virtual screening. Virtual screening and in vivo and in vitro experiments were carried out.
Results
The results showed that Tannic acid and Daptomycin had anti-RSV potential through reducing viral loads, inflammation, airway resistance and protecting alveolar integrity. And the IC50 values of tannic acid and daptomycin were the 6 nM and 0.45 µM, respectively.
Conclusions
Novel small-molecule inhibitors targeting the IGF1R, Tannic acid or Daptomycin, may be effective anti-RSV therapy agents.

Abstract
New organic acid-producing bacteria were isolated from buffalo rumens. The 29 of 46 isolates could produce succinic acid (SA), but only the 6 isolates had the potential. In shake flasks culture under CO2 condition, isolate no. 37 produced SA at a concentration of 2.28 g/L, and with a better inoculum, it produced SA at 6.74 g/L with a yield coefficient, Yp/s, productivity, rp, and efficiency, Ef of 0.45 g/g, 0.28 g/L/h and 66.39%, respectively within 24 h. The 16S rRNA gene of isolate 37 was sequenced identified. It is Enterobacter xiangfangensis, later named E. xiangfangensis BUU37 which is a high potential new industrial species. Its suitable N-, C-, and carbonate sources were yeast extract, glucose hydrolysate from cassava starch hydrolysis (CSH), and MgCO3. With the medium PM II-1x of nutrients rich, CSH glucose was used efficiently at 21.46 g/L and conversed to SA at 10.80 g/L with Yp/s of 0.50 g/g, rp of 0.45 g/L/h, and Ef of 76.33%, respectively. The larger-scale productions of SA in the 5-L fermenter, with certain optimum conditions, i.e., pH 6.8, at 39 °C, 0.5 vvm CO2 sparging, agitation, and high-nutrient compositions, gave very good results. The use of PM II-2x medium of 2× nutrients and 2× C-sources of 50 g/L CSH glucose plus 25 g/L molasses and with the impeller speeds at 200-400 rpm, SA was produced at 35.52 g/L with Yp/s of 0.65 g/g, rp of 1.48 g/L/h, and Ef of 99.96%, respectively. Furthermore, with the use of PM II-4x medium with 4× the nutrients and 4× the SCH glucose at 100 g/L plus 40 g/L of molasses (a total sugar conc of 120 g/L) and with the impeller speed at 400-500 rpm, SA was produced at 53.60 g/L with Yp/s of 0.54 g/g, rp of 2.23 g/L/h, and Ef of 82.88%, respectively. The use of PM II-4.8x medium of 4.8× nutrients did not show a significant difference. For the high throughput production, the PM II-4x cultivation was modified as the repeated multiple sequential batches of 3 cycles. The results showed no significant differences of those values among the cycles with the average values, of SA concentration of 54.01 g/L, Yp/s of 0.51 g/g, rp of 2.25 g/L/h, and Ef of 77.54%, respectively. The cell biomass of E. xiangfangensis BUU37 was produced at an average value of 5 g/L resulting in 1 g of dry cells producing 10 g of succinic acid giving the Yp/x of 10.80 g/g. With the maximum growth rate, µmax of 0.32 h-1 resulting within 24 h the highest SA production rate of >2.25 g/L/h which is higher than the values of other 50 research works. This new bacterial species, cultivation conditions, and methods can be scaled-up.

Authors: Bufarwa S. M. , Abdel-Latif S. A. 
Published: October 2022

Abstract
Elemental analysis, infrared (IR), proton nuclear magnetic resonance (1H NMR), and mass spectra were used to characterize (p-methylphenylazo)quinolin-8-ol (L1) and (p-methoxylphenylazo) quinolin-8-ol (L2). The important infrared (IR) spectral bands corresponding to the active groups in the two ligands and the solid complexes under investigation were studied. Also, the important fragments in the ligands and the complexes were determined using mass spectra, and the main peaks corresponded to the molecular weights of the ligands and complexes. The solid complexes have been synthesized and studied by elemental and thermal analyses (TG and DTA) as well as by IR, 1HNMR, magnetic measurements, electronic transitions, and molar conductance. The proposed steriochemical structures for the investigated metal complexes suggest octahedral geometry with respect to Mn, Ni, Cu, and Zn metal ions with the investigated ligands 1:1 and 1:2 complexes, and all of the formed complexes contain coordinated water molecules and hydrated water. All of the prepared solid complexes behave as non-electrolytes in chloroform.
Excess Iron added to the diet induces the apoptosis of chicken’s liver through the PI3KAKT mTOR axis

Published: October 2022

Abstract

Iron (Fe), an essential trace element, plays a key role in biological metabolism. The PI3K/AKT/mTOR axis plays an important role in the control of apoptosis. However, the effect of iron overdose in the diet on the role of the PI3K/AKT/mTOR axis and apoptosis, and pathological liver damage in chickens are still poorly understood. In this study, 180 1-day-old chicks were divided into 3 groups, which were fed the basal diets supplemented with 50 (C), 500 (E1), and 1000 (E2) mg Fe/Kg as ferrous sulfate monohydrate (FeSO4·H2O) and returned to normal diet one day later, Tested on days 1, 3, 7, 14, and 21 after the end of the iron addition. The results showed that the liver morphology was normal in the group C. The groups E1 and E2 showed the structure destroyed of hepatic lobules, the disordered of hepatic cords, the reduction of the central veins and the presence of erythrocytes accompanied by inflammatory cell infiltration. The group E2 showed more serious damage than the group E1, but these phenomena will largely return to normal on day 21. The perls staining showed that large deposits of iron-containing hemosiderin in the hepatic sinus after iron overdose intake, and the changes of iron deposition and pathological damage had certain regularity in time. The expression of Bax, Caspase-3, Caspase-8, and Caspase-9 in groups E1 and E2 were increased from days 1 to 21, which was in contrast to the Bcl-2, and it has a dose dependent. This suggested that iron overdose triggered apoptosis, which was supported by our ultrastructural observations of chromatin marginalization and impaired mitochondrial swelling. In addition, the expression of PI3K and AKT were significantly increased in the iron overdose groups, while the expression of mTOR was decreased. Above all, iron overdose can induce apoptosis in chicken hepatocytes through regulation of the PI3K/AKT/mTOR axis, leading to pathological damage. The type of iron overdose-induced damage was dose-dependent but not permanent. These results provide a theoretical basis for a comprehensive understanding of the importance of mineral nutrition management in poultry and the possible risk of excessive iron intake.
Synchronously recovering different nutrient ions from wastewater by using selective electrodialysis

Published: October 2022

Abstract
Digestive slurry normally contains various nutrient ions with high concentrations, including NH4+, PO43-, K+, Mg2+, Ca2+ and SO42-, which is a resource pool for nutrient recovery. In this study, a synchronously cationic and anionic selective electrodialysis (SCAE) was developed to recover anionic and cationic nutrient ions. Results showed that SCAE could synchronously recover more than 85.0%, 90.2% and 97.8% of PO43−, SO42- and other cations (including NH4+, K+, Ca2+, Mg2+) from the simulated digestive slurry, respectively. The ionic permeation sequence, NH4+ &gt; K+ &gt; Ca2+ &gt; Mg2+ for cations, and SO42− &gt; PO43− for anions, was affected by hydrated radius and hydration numbers, and did not alter despite the variation in electric field. High electrolyte concentration in the product streams would promote the recovery efficiency of both divalent cations and anions due to the ionic replacement effect and the demand for charge neutrality. Under continuous operation, the maximum concentrations of PO43−, SO42−, Mg2+, Ca2+, NH4+ and K+ in product streams reached 231.9, 496.6, 180.7, 604.3, 9,648.4 and 4,571.4 mg·L−1, respectively. By directly mixing different streams, the feasibility of producing mineral fertilizers without dosing externally precipitating chemicals was proved. Struvite, NH4HSO4 and potassium chloride minerals were produced successfully. The outcome provided an optional method for nutrient recovery from wastewater.
