Published: March 2022

Anthropogenic impact on the environment is growing every year. It deteriorates the living conditions of humans and other organisms and leads to global environmental crises. The atmosphere is especially sensitive to the influences in which processes progress more intensively than in other components of the environment. Kyiv takes one of the first places among the cities of Ukraine by the level of pollution. To make the necessary management decisions for improving air quality, detailed information is required about the level of air pollution, pollutants and sources of their formation, changes in time, etc. In developed countries, these functions are performed by different national pollution monitoring systems, which are automated and computerized and display real-time information. Today, the national environmental monitoring system in Ukraine is only being formed, so it is important to determine the most acceptable areas for its development.
The capital should be a model for other cities. Hence, a modern system of environmental monitoring should be one of the main priorities of the current city administration. Today, the monitoring of air quality in the capital is carried out by several entities. Conventionally, the main monitoring organization is the Central Geophysical Observatory (CGO), which has 16 monitoring points in Kyiv and publishes some (25 %) of the obtained information on its website. A significant advantage of the information from CGO is its compliance with current regulations of Ukraine. Such information includes all necessary contaminants. Today, CGO has the most detailed information about air quality for a long-term period. The last few years have been characterized by intensive development of private air quality monitoring systems in the capital: LUN City, Save Dnipro, Air Visual, luftdaten.info and others. They belong to various organizations, have sufficient coverage of the city, but analyze air quality only by the content of 1–10 µm particles, which is not enough for a complete analysis and assessment of air pollution. Most of these monitoring systems are more like advertising or designed to create a network of observation posts by citizens themselves. Therefore, such systems cannot be considered full-fledged air quality monitoring systems. Several years ago, the Kyiv City State Administration decided to create a modern open-resource automated air quality monitoring system in the capital. Today four observation posts have been installed. Such posts correspond to the current European level of air monitoring and provide real-time detailed information about the air pollution level.
The air quality monitoring system in the capital is likely to be developed by creation of new modern observation posts according to the Kyiv City State Administration program, especially if it is not commercialized or privatized in the future.
La naturalité à petit pas. Evolution des regards et des pratiques sur une notion émergente
Authors: Deuffic Philippe , Brahic Elodie , Dusacre Eve 
Published: March 2022

Si la forêt incarne la nature pour les Français, la notion de naturalité leur est beaucoup moins familière et leur semble relever du sauvage. Pourtant, certains signes montrent que ces représentations évoluent : les bois morts sont désormais tolérés, voire promus pour leur qualité écologique par les forestiers comme par le public ; les espaces dédiés à la naturalité tels que les réserves biologiques intégrales sont de plus en plus nombreuses sur le territoire métropolitain. Les raisons de cette adhésion restent cependant ambivalentes. Certains forestiers et usagers de la forêt le font pour éviter d’être accusé de négligence environnementale alors que d’autres sont vraiment convaincus de l’intérêt de laisser des espaces en libre évolution pour la biodiversité et la résilience des forêts face aux changements climatiques. Dans les deux cas, la naturalité retrouve progressivement et bon gré mal gré une place dans nos écosystèmes forestiers et nos représentations de la forêt.
La féralité : un concept novateur pour les forêts

Published: March 2022

De nombreux milieux agricoles ou prairiaux, laissés en libre évolution, évoluent vers des stades plus ou moins boisés en fonction des climats, des sols et des héritages anthropiques. Ces milieux en voie d’ensauvagement peuvent être assimilés à la nature férale. Il en existe beaucoup en France, liés à diverses crises économiques. Les plus anciennes ont entre 100 et 130 ans ; les plus jeunes entre 10 et 20 ans. Ils peuvent atteindre de grandes étendues dans la moitié sud de la France. Nous présentons quelques exemples de nature férale dans diverses parties de la France, dans la zone méditerranéenne, en moyenne montagne, en Bretagne ou le long des fleuves, afin de convaincre de l’intérêt de ces forêts férales pour la conservation des espèces en danger, des gros insectes aux grands mammifères. La nature férale française offre une formidable occasion, très concrète, de reconnaître la valeur intrinsèque de la nature sauvage.

Modelling Can Reduce Contamination from Mosquito Population Control

Published: March 2022

Abstract
Environmental contamination due to pest control in general, and mosquito control in particular, is an important issue expected to increase with climate change. We use a validated model for population dynamics of mosquitoes and historical environmental data to explore performance of larvicidal, adulticidal, and combined treatments. Results show that depending on treatment timing, larvicidal treatments can induce very good results, or have negative outcomes that increase overall mosquito population. Combined larvicidal and adulticidal treatments, however, exhibit much lesser dependence on timing, and therefore give the greatest chance of positive outcomes if environmental conditions are not known. Based on the results, we argue for adaptive mosquito management, in which weather data and forecasts are used to drive a model that identifies best intervals for insecticide use. Such an approach can have considerably better results than static, calendar-driven management and, therefore, considerably reduce environmental contamination. Adaptive management could consider larvicidal treatment because it gives good results if the timing is correct. Static management should, however, combine larvicidal and adulticidal treatments for the greatest chance of success.

Abstract
BackgroundThe traditional medicinal plant Centella asiatica (C. asiatica) is commonly used in Chinese and Ayuvedic medicine due to its vast range of therapeutic properties. Previously, the ethanolic C. asiatica leaf extract was subjected to silica column fractionation and the C3 fraction was obtained. We investigated the antioxidant and anti-proliferative effects of C3 in embryonic kidney (HEK293) cells.MethodsIn HEK293 cells, C3 cytotoxicity was assessed (Viability assay; 24 hours; [0.2–3 mg/ml]) and a half maximal inhibitory concentration (IC50) determined. Malondialdehyde (MDA), lactate dehydrogenase (LDH) (spectrophotometry), mitochondrial depolarization (Δψm), intracellular reactive oxygen species (flow cytometry), glutathione (GSH), oxidized glutathione (GSSG) concentrations, caspase activities, ATP levels (luminometry) and fragmentation of DNA (SCGE assay) were evaluated. Protein expressions were assessed by western blotting. Gene expressions were quantified by qPCR.ResultsCell viability in HEK293 cells was decreased in a dose dependent manner by C3. MDA, Δψm, LDH, caspase activities and DNA fragmentation (p < 0.0004) were significantly increased by C3. Nrf-2 protein expression, GSH and GSSG concentrations were increased whereas antioxidant (Nrf-2, GPx, SOD and CAT) gene expression was significantly decreased by C3 (p < 0.001). C3 decreased both Bax and Bcl-2 protein expression (p < 0.03). Gene expression of c-myc was significantly increased whereas OGG-1 was significantly reduced by C3 (p < 0.05).ConclusionCentella asiatica extract, C3, reduced antioxidant gene expression and elevated anti-proliferative effects in HEK293 cells, suggesting that C3 is potentially toxic to kidney cells at high concentrations thus rendering cause for concern from its association with human use.

Abstract
Purpose: Meaning in life (MIL) and family cohesion are important concerns for the palliative care population; however, evidence of the relationship between MIL and family cohesion is scarce. Therefore, this study aimed to examine the relationship between meaning in life and family cohesion, and explore the factors that influence MIL among the palliative care population.Methods: In this cross-sectional study, 205 patients with advanced cancer were recruited from two palliative care units in China. Data were collected using the Meaning in Life Scale (MiLS), the family cohesion subscale of the Family Adaptability and Cohesion Scale, second edition, Chinese version, and the Karnofsky Performance Status Scale (KPS). Multivariate linear regression models were used to examine the relationship between family cohesion and perceived MIL, and to identify the potential predictors of participants’ MiLS score.Results: The mean MiLS score was 100.90 (9.17). The results showed that family cohesion (r = 0.313, p < 0.01) and KPS scores (r = 0.311, p < 0.01) were positively correlated with MiLS scores. Multivariate linear regression revealed that MIL was significantly predicted by family cohesion, KPS score, sex, religiosity, whether participants lived alone, and their medical insurance payment method (F = 13.870, p < 0.01, R2 = 27.5%).Conclusions: Our findings indicate a positive relationship between family cohesion and MIL, suggesting that clinicians should consider increasing patients’ family cohesion as an approach to enhance perceived MIL.

Published: March 2022

Abstract
Background
Occupational exposure to wood dust particles has long been reported of its associated varying degrees of negative health effects due to different extractive chemicals present in the various timber species. However, tropical hardwood is also reported to have higher levels of extractive chemicals of anti-histamine, anti-oxidant and anti-inflammatory properties. In Ghana woodworkers have for years been exposed to wood dust from mixed tropical hardwood species, with little or no protective equipment such as nose masks, yet with less significant respiratory conditions. This study seeks to investigate the serum cytokine profile in tropical hardwood workers in Kumasi to provide a better understanding of the immunoregulatory pattern activated in the woodworkers.
Method
The study was carried out among woodworkers, teachers and security men located in Kumasi. A cross-sectional sampling of adult male workers was selected to participate in the study (86 woodworkers and 89 non-woodworkers). Participants donated blood collected by venepuncture into EDTA tubes and spun to separate serum for cytokine assay. Cytokines including IFN-Gamma, IL-1β, IL- 2, IL-4, IL-6, IL-10, IL-12, IL-13 and IL-17 were assayed using the Human Premixed Multi-analyte kit (R&D System, Inc. Minneapolis, USA) following the manufacturer’s procedure. The cytokine levels were quantified using the Luminex*200 analyser.
Results
The mean concentration levels for the various cytokines were significantly different (p < 0.05) between woodworkers and non-wood workers except IL-2. There were significantly increased levels of Th1 and Th2 cytokines expressed in the woodworkers more than the non-wood workers.
Conclusions
The results from this study reveal that exposed woodworkers of mixed tropical hardwood species show a high level of Th1 and Th2 cytokines in their serum than non-woodworkers.

Published: March 2022

Abstract
Sediment, nutrients, organic carbon and pollutants are funnelled down submarine canyons from continental shelves by sediment-laden flows called turbidity currents, which dominate particulate transfer to the deep sea. Post-glacial sea-level rise disconnected more than three quarters of the > 9000 submarine canyons worldwide from their former river or long-shore drift sediment inputs. Existing models therefore assume that land-detached submarine canyons are dormant in the present-day; however, monitoring has focused on land-attached canyons and this paradigm remains untested. Here we present the most detailed field measurements yet of turbidity currents within a land-detached submarine canyon, documenting a remarkably similar frequency (6 yr− 1) and speed (up to 5–8 ms− 1) to those in large land-attached submarine canyons. Major triggers such as storms or earthquakes are not required; instead, seasonal variations in cross-shelf sediment transport explain temporal-clustering of flows, and why the storm season is surprisingly absent of turbidity currents. As > 1000 other canyons have a similar configuration, we propose that contemporary deep-sea particulate transport via such land detached canyons may have been dramatically under-estimated.

Abstract
Background: Cardiac and respiratory motions in clinical positron emission tomography (PET) is a major contributor to inaccurate PET quantification and lesion characterisation. In this study, an elastic motion-correction (eMOCO) technique based on mass preservation optical flow is adapted and investigated for PET/MR applications. Methods: The eMOCO technique was investigated in a motion management QA phantom and in twenty-four patients who underwent PET/MR for dedicated liver imaging and nine patients for cardiac PET/MR evaluation. Data were acquired and then reconstructed with different gating modes and motion correction techniques and compared to static images. Standardized uptake value (SUV), signal-to-noise ratio (SNR) of lesions activities from each gating mode and correction technique were measured and there means/standard deviation (STD) were compared using 2-ways ANOVA analysis and post-hocTukey’s test.Results: Lesions’ s SNR are highly recovered from phantom and patient studies. The STD of the SUV resulted from the eMOCO technique was statistically significantly less (p<0.01) than the STD resulted from conventional gated and static SUVs at the liver, lung and heart.Conclusions: The eMOCO technique was successfully implemented in PET/MR imaging in a clinical setting and produced the lowest STD compared to gated and static images, and hence provided the least noisy PET images. Therefore, the eMOCO technique can potentially be used on PET/MRI for improved respiratory and cardiac motion correction.

Published: March 2022

Abstract
Background
The purpose of this study was to validate a fluorescein pen for use in corneal staining and to compare this novel technique with two conventional tools.
Methods
An insulin pen was converted into a fluorescein pen for use in corneal staining. The fluorescein pen was provided to 15 ophthalmologists for evaluating the ease of use as compared with two other tools (standard fluorescein strips and the 1 mL syringe method). Each fluorescein pen was used multiple times and underwent microbiological cultivation weekly. If the microbial culture was negative, the pen was used until the fluorescein in the cartridge was used up. Cornea fluorescein staining with three tools was conducted on 16 patients. Images were taken under slit lamp cobalt blue light to assess image quality and consistency.
Results
The average application span for the fluorescein pen was 87.7 ± 17.0 days (n = 15). No microbial growth was detected in any sample during the application period. Ophthalmologists’ assessments for ease of use via evaluation scores on a five-point Likert scale were 4.933 ± 0.26, 2.6 ± 0.83, and 2.2 ± 0.68 for the pen, strips, and syringe method, respectively. The fluorescein pen demonstrated greater ease of use than the other two tools (p < 0.0001). Image quality and consistency using the fluorescein pen were improved as compared with the other two tools.
Conclusions
We conclude that the fluorescein pen has several advantages over traditional staining methods, including greater ease of use, safety for multiple uses, and better yield in terms of improved corneal staining images.
Management, Prospects and Challenges of Akagera Wetland Management in the north-western Tanzania
Authors: Mkonda Msafiri Yusuph 
Published: March 2022

Abstract
Akagera is among the trans-boundary wetland ecosystems found in east Africa. Since the ecosystem serves the livelihoods of majority communities, it needs sustainable management to ensure its continued life support. This qualitative study serves to inform policy makers, socio-economic practitioners, development partners, and the communities at large on the prospects and challenges related to management of Akagera wetland. This establishment is particularly important in advancing on the existing body of knowledge. To execute such objective, the study identified some important resources found in the area, their socio-economic potentials, and challenges related to their management. Key informant interview and theme content analysis were the major methods for data collection and analysis, respectively. Here, the study exhibits that River Kagera, wildlife in national parks, wetlands, fertile soils and forests are among the most important resources found in the landscape. These resources serve as sources of water for domestic and agricultural production, energy, tourism, and meat, just to mention a few. Currently, the Tanzania National Parks which is a government institution manages the national parks and associated environmental resources in the landscape. Other resources such as water are managed by the respective sectoral ministries or in integration. However, some of the salient challenges associated with the management of Akagera wetland ecosystem include; financial constraint, poaching, forest deforestation, impacts of climate change, encroachment to wetland and national parks, cultural barriers, political instability, and unharmonized wildlife polices among the east African countries. Therefore, it is important to impose harmonized policies related to the management of this wetland ecosystem among the benefiting countries, strengthen joint patrols, and raise awareness among the people on the management of all trans-boundary resources in east African region. This study proposes further researches in the landscape especially on the political and social cultural barriers related to the management.
