Aim. We aimed to study the histological and thrombotic changes in lung vessels in patients who died with COVID-19, to access the correlation between anticoagulation therapy (ACT) and thrombotic events (TE), treatment results, clinical and laboratory patients' characteristics.Material and Methods. We retrospectively analyzed treatment results of patients hospitalized with COVID-19 and lung vessel samples of the deceased patients. Dynamic changes and highest levels of D-dimer and fibrinogen were studied in its correlation with the disease severity according to SOFA score, computer tomographic (CT) results, lung, renal and hepatic dysfunction. The association between different doses of ACT and treatment results, laboratory indicators and thrombotic events was accessed. The histological lung vessels examination was performed using Martius Scarlet Blue (MSB)staining.Results. 313 patients were included in the study (61 patients died). The median age of hospitalized patients was 60 years (IQR 51-66 years). The frequency of the intravitallyconfirmed TE was 4,8%. The strong statistical association was revealed between D-dimer level and 3-4 points SOFA score, patients' mortality, oxygen support requirement, CT3-CT4 pneumonia, glomerular filtration rate and TE. There was no mortality in patients with D-dimer normal references, but in cases with three times elevation reached 13%, 48,5% - in cases with 3-6 times elevation and 64,6% - in cases with more than 6 times elevation. The strong statistical association was registered between fibrinogen and SOFA score, CT 3-4 pneumonia, patients' mortality. D-dimer and fibrinogen levels demonstrated weak correlation. There was no statistical correlation between prophylactic, intermediate and therapeutic ACT and D-dimer and fibrinogen levels, CT results, patients' mortality. MSBstaining was used in 36 deceased patients tissue samples. 1394 lung vessels were analyzed. Lung vessels thrombi persisted in samples of all 36 patients (100%). Vessels with the diameter 3,5-30 mm were thrombosed in 7%, with the diameter 0,034-0,84 mm - in 48%, with the diameter 0,85-3,4 mm - in 45%. The frequency of thrombi persisted 06 hours, 6-12 hours, 12-18hours, 18-24 hours and more than 24 hours was12%, 14%, 62%, 5% and 7% respectively.Conclusion. Thrombi of different ages from fresh to organized were observed in one third of lung vessels in all deceased patients. Lung vessels thrombosis plays an important role in pathogenesis and thanatogenesis of COVID-19. The D-dimer level correlates with lung, renal dysfunction, patients' mortality and doesn't show any correlation with ACT and can be accepted as a criterion of lung vessel thrombotic progression.

» Magnetic resonance imaging (MRI) without contrast is sufficient to diagnose an intra-articular ganglion cyst of the knee. MRI with intravenous contrast may be considered for cysts in the infrapatellar fat pad, which are not a typical presentation.» The current literature supports treating symptomatic cases or those discovered accidently during knee arthroscopy with arthroscopic excision.» Although aspiration of these cysts results in a higher recurrence rate than excision, it is associated with quicker recovery. Thus, aspiration might be chosen as an initial treatment for anyone who would like to avoid surgery or requires a rapid recovery, including professional athletes.» Open excision may be considered for infrapatellar fat pad cysts that are >4.5 cm in size.

Abstract

Bacteria, inhabiting around and in plant roots, confer many beneficial traits to promote plant growth and health. The secretion of root exudates modulates the nutritional state of the rhizosphere and root area, further selecting specific bacteria taxa and shaping the bacteria communities. Many studies of the rhizosphere effects have demonstrated that selection by the plant rhizosphere consistently enriches a set of bacteria taxa, and this is conserved across different plant species. Root selection effects are often considered to be a strong selective force than the rhizosphere, yet studies are limited. Here, we focus on the root selection effects across a group of 11 stress-resistant plant species. We found that the root selection consistently reduced the alpha diversity (represented by number of observed species, Shannon’s diversity, and phylogenetic diversity) and altered the structure and composition of bacteria communities. Furthermore, root selection tended to enrich for clusters of bacterial genera including Pantoea, Akkermansia, Blautia, Acinetobacter, Burkholderia-Paraburkholderia, Novosphingobium, Massilia, Pseudomonas, Chryseobacterium, and Stenotrophomonas. Our study offers some basic knowledge for understanding the microbial ecology of the plant root, and suggests that several bacteria genera are of interest for future studies.

Published: September 2022

Abstract
Aims: This study aims to determine the influencing factors for adverse pregnancy outcomes by comparing the blood tests and pregnancy outcomes of pregnant women with different types of thalassemia minor and iron deficiency anemia.Methods: A retrospective case-control study was conducted on singleton pregnant women in our hospital from January 2019 to November 2021. Included four study groups αTT group(n=106), βTT group(n=162),TT&IDA group(n=108), IDA group(n=81). The normal pregnant women during the same period were the control group(n=546).Results: The cesarean rate of the four study groups was significantly higher than that of the control group, and the rate of fetal lung maturation in the αTT, βTT and TT&IDA groups was lower. The levels of Hb, HCT, MCV, MCH, and MCHC in the four groups were lower, while RDW was significantly higher than that in the control group. The incidence of adverse maternal outcomes in the 4 groups was lower, but the incidence of intrahepatic cholestasis of pregnancy in the αTT and βTT groups was higher than that in the control group.Conclusions: The results suggest that Mediterranean disease characteristics and IDA have an effect on some adverse maternal outcomes, but don’t increase adverse neonatal outcomes. Women with βTT had more severe anemia. Iron supplementation for pregnant women without anemia will increase the risk of gestational diabetes. It is recommended to regard the Hb level in the first 3 months of pregnancy as a high-risk factor for gestational diabetes and not recommend routine iron supplementation for women with high Hb.

Abstract
As a toxic and harmful global pollutant, mercury (Hg) enters the marine environment through natural sources, and human activities. It bioaccumulates through the food chain and therefore Hg is of great importance for environmental monitoring. This study aims to answer the question if Hg contamination in fish and sediment from the German Bight follow temporal trends. Therefore, 496 individual female dab (Limanda limanda) were analysed. The Hg concentrations in muscle of dab from the German Bight showed significant increase in function of time with an annual percental change of 1.4%, leading to a 41% increase in Hg-contamination level within 25 years of monitoring. At the same time Hg levels in sediment – analysed in 86 samples - significantly decreased in the nearby North Sea environment. This surprising contradiction is shown in the present study and possible causes are discussed. It could be clearly shown that contamination in sediment and biota can follow completely different time courses and therefore different environmental matrices should be considered in future monitoring studies. Age of the fish turned out to be a biological factor of particular importance for temporal trend analysis.

Abstract

This study aims to investigate the pollution by heavy metals in the surface sediments of Hourolazim Wetland (HW) using pollution indices and statistical analysis of 16 samples from 8 stations at a distance of 50m from oil drilling sites. Based on the results, the average concentrations of Pb, Zn, V, and Cr are 40.7, 103.1, 135.5, and 115.8, respectively, which are higher than the average shale values. The results of heavy metal concentrations based on the geo-accumulation Index (Igeo) show that As, Zn, Ni, V, and Cr have low enrichment while Pb has medium enrichment, with the latter showing an alarming condition. Also, based on the contamination factor (CF), Pb with an average value of 2.03 and moderate level of pollution has the highest level of pollution warning compared with other elements. Modified contamination degree (mCd) for St3 and St4 is 1.61 and 1.56, respectively indicating low level of pollution. The enrichment factor (EF) for lead represents the average level of enrichment. Cluster analysis for the metals shows that V and Ni lie in one cluster while the rest of the metals (As, Pb, Zn, and Cr) lie in the other. Further, cluster analysis for the studied stations shows that stations St3, St4, and St7 are located in one cluster whereas, stations St1, St2, St5, St6, and St8 in another cluster that has the high compliance with the average of the combined pollution index. High correlation between some metals and sampling stations with cluster analysis provide insights into the same level of contamination and an approximate contamination source for these metals.
Study on the influence of tooth surface wear on the lubrication performance of double involute gear transmission

Published: September 2022

Abstract
To improve the lubrication performance of double involute gears(DIGs) and reduce tooth surface wear, this paper establishes a quasi-static tooth surface wear (TSW) analysis model according to the modified Archard wear equation under the mixed elastohydrodynamic lubrication (EHL) condition, and proposes a numerical calculation method for the lubrication characteristics considering the influence of TSW based on the coupling relationship between TSW, meshing characteristics and lubrication characteristics. Based on this, the effect of TSW on lubrication characteristics with the working condition parameters, tooth waist order parameters and roughness is also studied. The research shows that the effect of TSW on the lubrication characteristics of DIGs is closely related to the accumulated tooth surface wear depth. TSW can deteriorate the lubrication state between meshing tooth surfaces, the early TSW under the mixed EHL state has less effect on its lubrication characteristics, and has significant influence on the lubrication characteristics near the meshing in and meshing out positions. Under the conditions of low velocity, high torque and large roughness, TSW has a greater effect on the lubrication characteristics.However, the influence of TSW on the lubrication characteristics is small with the variation of tooth waist order parameters.

Abstract

The aim of this study was to assess the effectiveness of open defecation free (ODF) system on the incidence of faecal contamination on environment (water, soil and food mediums). The magnitude of contamination of environmental medium of ODF and non-open defecation free (n-ODF) villages by faecal indicator bacteria (FIB) in three states of India, was investigated. The FIB positive samples were further processed to determine the source of faecal contamination using Bacteroidale molecular markers for human (HuBac). The matrix of relative risk (RR) due to FIB and HuBaC contamination was developed to assess the effectiveness of ODF interventions. When compared to ODF villages, the RR of faecal contamination in n-ODF villages was estimated 11.25 times more likely in groundwater, 2.68 times more likely in household storage drinking water, 2.71 times more likely in piped water supplies, 1.13 times more likely in soil and 1.48 times more likely in food. The RR of faecal contamination traceable to humans was estimated 12.66, 2.48, 2.40, 1.10 and 2.16 times more likely in n-ODF villages as compared to ODF villages in cases of groundwater, household storage drinking water, piped water supplies, soil and food respectively. The risk assessment matrix designed in present study can be useful towards evaluation of the performance of ODF missions being implemented in many developing countries to achieve sanitation and hygiene objectives in accordance to the target 6.2 of Sustainable Development Goals 2030.

Published: September 2022

Abstract
Stagnant wetlands have a vast natural ecosystem of different sizes, provide vital ecosystem services to humans, but are not well detailed. The study investigates the association of the Stagnant wetland’s size versus the ecological condition (EC), ecosystem service (ES), and their Shifts in land use / land cover (LULC) in the Agro-climatic a location of Namakkal district. Twenty-one chosen wetlands are hydrologically isolated, few semi-parched in summer, surveyed by the range of methods. The Wetland sizes had categorized into small wetlands (SW), medium wetlands (MW), and large wetlands (LW) which, are less than 10 acres, 11 to 100, and above 100 acres, respectively. Our results showed that ES of entire wetlands degraded by human anthropogenic activities and degradation factors differ in the wetland kinds. Also, ecosystem services such as livestock rearing and agronomy are vital income sources. Overall, the hypothesis results show that wetland size is not associated with ecological status and ecosystem services. However, the LULC changes had analyzed from 2010 to 2019. The data corroborate that the increase in constructing the property and extensive changes in agricultural areas are a deep concern for wetland size reduction. Finally, wetlands conservation activities priorities given to are wetlands size-based seems not the best practice.

Abstract
Saint Martin’s Island, being the only coral formed island in Bangladesh, a huge number of tourists visit the island during August until April (is not correct the months). The island is faced with extreme anthropogenic pressure due to the increasing number of tourists and improper management of the island infrastructure and surrounding ecosystem. The study was carried out to determine the clean and hygienic quality of recreational beach water (RBW) in front of the resorts and island’s offshore water (OW) by collecting water samples from fourteen locations during peak tourist season (February 2021) and non-tourist season (April 2021) in high tide condition. The membrane filtration method from the APHA standard was used to assess total coliform and faecal coliform in the water samples. Total coliform counts (>200 CFU/100 ml) were measured using Bangladeshi Department of Environment (DOE) standards, whereas faecal coliform counts (>100 CFU/100 ml) were measured using Malaysian Department of Environment (DOE) standards. The study found a detrimental amount of E. Coli bacteria in the RBW and OW of the SMI. Total coliform levels in RBW from the island ranged from 15.33 to 657.22 CFU/100 ml, whereas faecal coliform levels varied from 1.37 to 272.31 CFU/100 ml. Total coliform levels varied from 26.34 to 1810.10 CFU/100 ml in the OW, while faecal coliform counts were 32.31 to 280.54 CFU/100 ml. During the tourist season, there was 63% more bacterial pollution than at any other time. The highest levels of total coliforms were present in the OW on the western shore of the island, freshwater wetland, and jetty ghat, while lesser numbers were detected in the RBW of resorts in the tourist season. The most faecal coliforms were found from offshore water on the western & eastern sides of the island, jetty ghat, and beach of Shayari resort in tourist season.
The ‘lawnification’ of Australia’s eastern grassy woodlands: The past, current and likely future spread of a damaging pasture and lawn grass, Bothriochloa pertusa
Authors: Lebbink Gabrielle , Fensham Rod 
Published: September 2022

Abstract
Many of today’s damaging invasive plants were intentionally introduced for pasture development. By examining the introduction history and consequent spread of these species, we can identify factors associated with their successful establishment and dominance. Using collated presence/absence and cover data, alongside a review of the literature and discussions with land managers, we present a comprehensive analysis of the introduction history and spread of the invasive perennial grass species, Bothriochloa pertusa throughout Queensland, Australia. Using this data, we also perform habitat suitability models to predict its potential distribution and local-scale cover across Queensland in relation to key environmental variables. We found that B. pertusa was introduced on multiple occasions and across a large area of Queensland, despite re-occurring doubts and poor evidence for its benefit to livestock production. Livestock grazing, associated disturbances (i.e. land clearing, soil erosion) and climatic extremes were commonly associated with its spread throughout the landscape. In 2020 the main area of B. pertusa invasion as indicated by occurrence records spanned 28,537,600 ha. Results from the habitat suitability models suggest the occurrence and local-scale cover of B. pertusa is largely determined by climate variables and the foliage projective cover of trees. Based on these results B. pertusa still has considerable capacity to spread and increase in dominance across many areas of Queensland, particularly further west and south of its current range. The introduction and spread history of B. pertusa suggests propagule pressure, traits, climate, land management and cultural perceptions are all key factors implicated in the spread of B. pertusa. We recommend more conservative grazing strategies and strategically selected protected areas to slow the spread of this species.

Published: September 2022

Abstract
Background
To investigate the safety, feasibility, and oncological outcomes of total laparoscopic right hemicolectomy with transvaginal specimen extraction in the treatment of right-sided colon cancer.
Methods
We retrospectively reviewed patients with right-sided colon cancer who received total laparoscopic right hemicolectomy in our hospital between January 2017 and January 2020. The patients who underwent abdominal incision were included in the control group and the patients who underwent vaginal incision group were included in the study group. The perioperative characteristics and outcomes were compared between these two groups.
Results
25 patients were included in the study group and 55 patients were included in the control group. In terms of baseline data, including age, preoperative body mass index, American Society of Anesthesiologists classification, tumor transverse diameter, tumor location, pathologic differentiation, preoperative clinical staging, there were no significant differences between the two groups (P > 0.05). There were no significant differences in terms of operative duration, intraoperative blood loss, length of resected colon, number of detected lymph nodes, postoperative complications, and postoperative pathological stages between the two groups (P > 0.05). There were statistically significant differences in postoperative pain intensity, time to passage of flatus, and length of postoperative hospital stay between the two groups (P < 0.05). The sexual function index survey showed a statistically significant difference at 3 months (P < 0.05), but not 6 months (P > 0.05), after the surgery between the two groups. The one-year tumor-free survival rate was 100% in both groups.
Conclusions
Total laparoscopic right hemicolectomy with transvaginal specimen extraction is a safe and feasible method, with satisfactory oncological outcomes, to treat patients with right-sided colon cancer.
