Керуючись новими нормативними вимогами, що введені 7-ою поправкою до Регламенту Європейського парламенту та Ради Європейського Союзу № 1223/2009 «Про косметичні засоби» дослідники в галузі косметичної промисловості зобов’язані розробити та оцінити альтернативні стратегії тестування, такі як аналізи in vitro, підходи in silico для токсикологічних аналізів та досліджень ефективності косметичних продуктів та косметичних інгредієнтів. Як наслідок, Європейський центр перевірки альтернативних методів (ECVAM) затвердив список валідованих клітинних моделей in vitro для прогнозування безпеки та токсичності косметичних інгредієнтів. Ці моделі є ефективними та альтернативними інструментами для подолання обмежень досліджень на тваринах in vivo, в звязку з слідуванню принципу 3R. Оскільки всі дослідження, що проводяться на тваринах є жорстокими по відношенню до піддослідних тварин, під час яких вони зазнають страждань і гинуть. Проте досі існують методики, що не мають альтернативи серед in vitro методик. У цьому огляді представлено основні альтернативні моделі in vitro, які використовуються в тестах безпеки косметичних продуктів, що зосереджені на сенсибілізації шкіри, роз’їданні шкіри, подразненні шкіри та поглинанні шкірою. Також наведено огляд використання 3Д технологій, які є перспективним для оцінки токсичності речовин, що містяться в косметиці, особливо для аналізу токсичності повторних доз, для якого наразі немає альтернативних методів in vitro. Проте ці технології, потребують доопрацювання і проведення перевірки та прийняття регуляторними органами як ефективний метод. Для досягнення цієї перевірки знадобиться співпраця між дослідниками, регуляторними організаціями та промисловістю. Для українського ринку косметичних продуктів робота над альтернативою in vivo дослідженням, які передбачають використанням лабораторних тварин, також являється важливим та перспективним напрямом. Таке як відбувається гармонізація нормативного законодавства України з законодавством Європейського Союзу, і введення в дію вимог технічного регламенту щодо косметичної продукції передбачається в серпні 2024 року.

Orphan No More—Federal Funds Begin Flowing to State Coffers for Orphan Well Remediation
Authors: Presley Jennifer 
Published: April 2023

Billions of dollars in federal funding secured under the 2021 Bipartisan Infrastructure Investment and Jobs Law (BIL) has started flowing into US state coffers for the plugging and remediation of orphan oil and gas wells.
Signed into law in November 2021, the BIL is a $1.2 trillion “once-in-a-generation investment” that includes $4.7 billion in funding to plug and remediate orphan wells across the nation. According to the US Department of the Interior (DOI), these legacy pollution sites are environmental hazards and jeopardize public health and safety by contaminating groundwater, emitting noxious gases and methane, littering the landscape with rusted and dangerous equipment, and harming wildlife.
The US Environmental Protection Agency (EPA) estimated in a 2020 inventory of greenhouse gas emissions that, on average, each unplugged abandoned oil and gas well emits 0.13 tons of methane per year.
When multiplied by an estimated 2.1 million unplugged, abandoned oil and gas wells, the EPA estimated methane emissions of 276,472 tons in 2019, equivalent to roughly 9.5 mtpa of carbon dioxide (CO2) assuming a 100-year global warming potential (GWP) of 34.
This is roughly 2.6% of total US energy-related methane emissions or roughly 0.2% of total US energy-related greenhouse gas emissions in 2019, assuming a 100-year GWP for methane of 34, according to a report published in Environmental Science & Technology.
The Intergovernmental Panel on Climate Change defines GWP as the cumulative radiative forcing, both direct and indirect effects, over a specified time horizon resulting from the emission of a unit mass of gas related to some reference gas.
While the EPA pegs the number of orphaned wells in the millions, there are variations in the count, depending on how each state or organization defines what is and is not an orphaned well. A survey, for example, by the Interstate Oil and Gas Compact Commission in 2018 put the range of orphaned and idle wells at around 560,000 to 1.1 million.
According to the Railroad Commission of Texas (RRC), the regulatory body that oversees Texas oil and natural gas development, an orphan well is an inactive and unplugged well that has not produced oil or natural gas for a minimum of 12 months.
But the Colorado Oil & Gas Conservation Commission defines an orphan as a well which has no owner or operator that can be found, or where the owner or operator is unwilling or unable to plug and abandon such a well. This JPT article described the hunt for the potentially hundreds of thousands of unknown, undocumented orphans across the country.
In October 2021, the Environmental Defense Fund (EDF) released a map showing the location of more than 81,000 documented orphan wells in 28 states that are eligible for funding under the BIL. In the spring of 2022, thanks in part to states documenting more than 40,000 additional orphan wells, EDF released an updated map showing more than 120,000 documented orphan wells in 30 states (Fig. 1).
Geomechanical Modeling of Fracture-Induced Vertical Strain Measured by Distributed Fiber-Optic Strain Sensing
Authors: Srinivasan Aishwarya , Liu Yongzan , Wu Kan , Jin Ge , Moridis George 
Published: April 2023

Summary
Distributed acoustic sensing (DAS) has recently gained importance in monitoring hydraulic fracturing treatments in the oil and gas industry. DAS data contain critical information about the fracture geometry as linearly relatable induced strain variations during the stimulation. The low-frequency components of the DAS (LF-DAS) data are known for their complexity as they exhibit various characteristic signals—caused by several mechanisms—that complicate their interpretation. LF-DAS data from horizontal monitoring wells (HMWs) have been used to detect fracture hits and characterize fracture geometry. However, the LF-DAS data from vertical monitoring wells (VMWs) have not been studied extensively as a means to infer fracture geometry. The major limitation of VMWs is the number of monitored stages, but the data contain more information about fracture height compared with LF-DAS measurements from HMWs. Hence, it is necessary to have a physical rock deformation model to simulate the strain rate responses in offset VMWs during fracture propagation to understand and interpret the various patterns that are observed in the field data sets.
The objective of this study is to simulate strain rate signals in VMWs during hydraulic fracturing and to analyze the measurements to obtain information on the fracture geometry, especially the fracture height. The fracture boundary can be directly related to the strain rate signals. In this study, we propose a workflow to determine fracture height at different fiber-to-fracture (dff) distances for fracture heights ranging from 20 m to 300 m. We conduct a detailed sensitivity analysis to understand the impacts of the dff, the perforation location, the fracture passing time, and the well inclinations on the measured strain rate signals. The analysis helps interpret the various patterns observed in field data and the underlying mechanisms. Interpretation of field data from the Hydraulic Fracture Testing Site 2 (HFTS-2) using the results from our forward physical model provides valuable information on the fracture characteristics that can be captured by the physical model. The results of this study are expected to provide better interpretations of LF-DAS signals from VMWs.

Abstract
Measures of graph entropy have been widely used in information theory, biology, chemistry, and sociology, among other disciplines. The entropy of a probability distribution may be thought of as both an indicator of information and an indicator of uncertainty, and it is a number used in information theory to gauge the complexity of a graph. Mathematical and medicinal chemistry, including drug design, have previously made extensive use of information-theoretic network complexity measurements. Dendrimers belong to the world of molecular chemistry for stepwise controlled synthesis and to the world of polymers for repeating structures from monomers. A topological index is a numerical metric that describes the topology of a graph. Consequently , a topological index calculated for a molecular network is a quantitative indicator of molecular topology. Due to the simplicity of production and the speed at which these computations may be performed, these descriptors have gained great prominence in recent years. Characterizing molecular structure using topological methods, including numerical graph invariants, is a current trend in mathematics and computational chemistry. Such conceptual descriptors have also launched a broad range of applications in QSAR/QSPR investigations and is ideal for innovative molecular design, drug development, and risk assessment of chemicals. In this paper, various entropy measures along with the distance and degree based topological indices of highly efficient iridium cored electrophosphorescent dendrimer has been evaluated. Entropy measure is a topological feature that may be used to assess the complexity of chemical compounds.

Abstract
Brugada syndrome (BS) is a hereditary cardiac channelopathy associated with premature sudden cardiac death and arrhythmic events. However, there are limited data on prevalence of BS in Iran. This study aimed to evaluate the prevalence of BS and Brugada pattern on the electrocardiogram (ECG) in a general population located in south of Iran. BS and Brugada pattern were defined as the presence of type I and type II-III Brugada spontaneously or after a sodium channel blocker test, respectively. A total of 4000 participants (52.3% women) were enrolled in this study. Only 12 patients (0.3%) had Brugada ECG pattern and 4 ECGs were consistent with BS (0.1%). All 16 cases were followed up for 60 months. No mortality or cardiovascular events were observed during this period. This study showed a very low prevalence of BS and Brugada pattern in ECG in the general population of Iran.

Published: April 2023

Abstract
The viral strains of the Newcastle disease virus have exhibited genetic and pathogenic diversity since their discovery, which is mainly influenced by mutations in the Fusion gene. This study focused on describing the circulating Newcastle disease virus strain based on the Fusion gene sequencing of three isolates: JKND01, JKND02, and JKND03, which were isolated from commercial poultry in Kashmir. Phylogenetic analysis identified the isolates as Genotype VIIi with the virulent fusion cleavage site motif (113RQKRF117). Homology analysis of amino acid sequences identified amino acid substitutions in the Fusion protein of the isolates compared to the reference strains. In silico mutational analysis revealed that the amino acid changes impact the structure of the protein, potentially affecting the functional behaviour of the virus. Moreover, predictive analysis of potential post-translational modification motifs showed a loss of an N-glycosylation site and the acquisition of a phosphorylation site in JKND02 compared to the reference Fusion glycoprotein. This study reports the first presence of the fifth panzootic vNDV genotype VIIi in Kashmir, highlighting the need for further epidemiological and surveillance studies to better understand the distribution and spread of the virus and to develop effective control measures.

Authors: Arthur Jones Lewis , Owusu Edward , Arthur Sonny Davis 
Published: April 2023

Abstract
The study uses a quantitative research approach to explore the strategies that SMEs have adopted to cope with issues relating to energy security. A sample of 205 owners of enterprises was sampled from an appropriation of 500 SMEs in the Accra Metropolis of the Greater Accra Region. The cluster method and simple random sampling approaches were used to select the respondents. Data collected through questionnaires were edited and cleaned to ensure completeness, consistency and legibility. Descriptive, exploratory and inferential analyses were applied to guide the study of the results. SMEs stand to benefit from energy security if they can able to apply strategies to embrace sustainable energy practices that explore opportunities in renewable energy sources. SMEs in the wholesale and retail business sectors are better able to cope with the challenges of ES due to several strategy options such as exploiting renewable energy power, reducing energy consumption, using generators, reducing energy consumption and temporarily suspending business. There are few energy sources available to SMEs, thus limiting the strategy options that could be applied to cope with challenges in ES. SMEs should invest in other sources of energy especially renewable energy such as solar energy to achieve energy security.

Abstract
Background Mosquito borne pathogens are a threat to human health and can be difficult to detect especially when they cause a high rate of asymptomatic infections in human. The discovery that infected mosquitoes can release viruses in both their saliva and secreta gave rise to low-cost methods for the early detection of arboviruses during entomological surveillance.Methods Here, we implemented both saliva and excreta-based entomological surveillance during the emergence of Zika virus (ZIKV) in French Guiana in 2016 by trapping mosquitoes around households of confirmed ZIKV symptomatic cases.Results ZIKV was detected in mosquito excreta and not in mosquito saliva in one trap collection out of 85 (1.2%) throughout the survey. One female Ae. aegypti was found with a ZIKV systemic infection in the corresponding trap. The lag time between symptom onset declared by the ZIKV infected individual living in this site and ZIKV detection detected in this mosquito was one week.Conclusions Altogether, these results highlight the potential of trapped mosquito excreta as a sensitive and cost-effective method to non-invasively detect arbovirus circulation.

Published: April 2023

Abstract
In order to achieve rapid acquisition, identification and measurement of the average ray height of softwood based on tangential section photographs, a new method is proposed. Firstly, labels the digital image of the softwood tangential section with the 100 magnification, that is, mark the rays and scales on the image, and establish the dataset; Secondly, the dataset is randomly divided into training set and validation set. YOLOv5s is used for model training to obtain the best target recognition model of rays and scale. The experimental results show that the model trained with YOLOv5s can achieve 93.5% accuracy, 95.6% recall and 96.7% average accuracy in the validation set; Thirdly, using the YOLOv5s trained model, a visual program for automatically calculating the ray height and obtaining the ray characteristics of softwood is designed, which lowered the threshold for wood identification workers to use such software.

Published: April 2023

Abstract
Cyanobacterium Nostoc commune has long been used to alleviate various diseases. This research aims to examine the effects of Nostoc commune extract (NCE) against behavioral disorders, cerebral oxidative stress, and inflammatory damage in the ketamine-induced schizophrenia model. Oral NCE administration (70 and 150 mg/kg/d) is performed after intraperitoneal ketamine injection (20 mg/kg) for 14 consecutive days. The forced swimming and open field tests are used to assess schizophrenia-like behaviors. After the behavioral test, dopamine (DA) level, oxidative stress markers, as well as the interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) expression are measured in the cerebral cortex. Based on the obtained results, NCE treatment ameliorates KET-induced anxiety and depressive-like behaviors in OFT and FST, respectively. NCE considerably decreases the malondialdehyde (MDA) and DA levels, as well as IL-6 and TNF-α expressions, in mice with schizophrenia-like symptoms. Also, a significant increase is observed in the glutathione (GSH) level and catalase (CAT), superoxide dismutase (SOD), and glutathione reductase (GRx) activity in cerebral tissue. The present study shows that NCE treatment effectively improves KET-induced schizophrenia-like behaviors and oxidative and inflammatory damage. Therefore, NCE, via its bioactive constituents, could have strong neuroprotective effects in the schizophrenia-like model.
