Determining Stress Orientation in Rock Valley, Nevada, Using Ambient Seismic Noise
Authors: Delorey Andrew A. 
Published: May 2024

AbstractThe stress field and the mechanical properties of rocks are important to consider for nuclear explosion monitoring due to their effect on seismic wave radiation from earthquakes and explosions. At the Rock Valley Direct Comparison site, the regional orientation of the maximum horizontal compressive stress (SHmax) is well constrained, but it is unknown whether there are local heterogeneities. Here, I show that stress-induced anisotropy in nonlinear elasticity can be used to estimate the orientation of SHmax. Rocks have compliant internal contacts, such as fractures and mineral grain boundaries, that respond to applied strains more strongly than individual mineral crystals. This strain response is asymmetric between compressive and dilatational strains and is affected by anisotropy in the ambient stress field. Traditional seismic velocity measurements are of strain-averaged velocity, which is less sensitive than nonlinear elasticity to the behavior of compliant internal contacts and therefore the stress field and fracture behavior. My results show that the orientation of SHmax measured using ambient seismic noise aligns with regional estimates, with some heterogeneity that can also be explained by the limitations of the seismic array. I demonstrate the potential of a passive technique for monitoring the stress field in places that currently lack local measurements.
Uncommon presentation of duodenal gastrointestinal stromal tumor as large paraduodenal cyst: case report
Authors: Kerkar Prashant B. , Sabireen  , Pohekar Monika , Mohanty Mahesh 
Published: May 2024

Gastrointestinal stromal tumors (GISTs) are rare solid mesenchymal neoplasms. Small bowel GISTs have predominantly an outward growth and multifocal when associated with neurofibromatosis-1 (NF-1). When the duodenum is involved, lesions may be more challenging if growing towards the pancreas. Their prevalence is unknown, and diagnosis is usually incidental. Owing to the complex anatomy of the duodenum and pancreatic head, GISTs can be misdiagnosed as pancreatic head tumors, however they presenting as cyst is very rare. Literature shows very few reported cases of cystic GISTS, all arising from the stomach or pancreas where they have been mistaken for pseudocysts or even a mucinous cystadenocarcinoma of the pancreas and only one case of duodenal GIST presenting as cyst has been reported so far. Here, we report a case where investigations including radiology and upper gastrointestinal endoscopy suggested it to be a paraduodenal cyst, but histopathological examination of the specimen resulted in an unexpected diagnosis of GIST. We concluded that non-invasive imaging like CT, MRI, EUS and whenever possible FNA are important for the diagnosis and treatment of GISTs. Surgical resection with clear margin is the desired treatment for a localised duodenal GIST. Also, the feasibility of limited resections such as duodenectomy without pancreatic/ampullary involvement as in our case report where we preserved the pancreas reduces the morbidity and complications associated with extensive surgeries like pancreaticoduodenectomy. Also, Imatinib is an effective therapeutic agent with a remarkable response and prolonged survival.
Unlocking Bioactive Potential: A Comparative Analysis of Solvent Extraction on Phytochemicals and Antimicrobial Efficacy in <i>Eupatorium glandulosum</i> and <i>Eupatorium odoratum</i>

Published: May 2024

The purpose of this work was to explore and compare the phytochemical constitution, vitamin composition, antioxidant activity, and antimicrobial potential of leaf extracts from two Ethnomedicinal plants, Eupatorium glandulosum and Eupatorium odoratum, belonging to family Asteraceae collected from the Eastern Himalayan Darjeeling region and the plains of Jhargram in West Bengal, India. Four distinct solvents viz., 80 % aqueous ethanol, ethyl acetate, chloroform and n-hexane were used to prepare the leaf extracts. The identification and quantification of phytochemicals and water-soluble vitamins was conducted through HPLC. To evaluate antioxidant potential, 2,2-Diphenyl-1-picryl hydrazyl (DPPH), 2,2-azino-bis-3-ethylbenzothiazoline-6-sulphonic acid (ABTS), and Ferric Reducing Antioxidant Power (FRAP) assays were performed. The antimicrobial activity was investigated against Streptocococcal strains (S. oralis, S. mutans, S. pyogenes). Both the plants exhibited a diverse array of identified phytochemicals. E. glandulosum contained five while E. odoratum presented an even richer composition of seven water-soluble vitamins. Remarkably, E. odoratum displayed the highest scavenging activity against DPPH radicals (70.08%), and notable reducing potential (10.74 AAE mg/gm). In contrast, E. glandulosum showcased pronounced scavenging potential against ABTS radicals (74.32%). Additionally, the ethyl acetate extract from E. odoratum displayed robust antimicrobial efficacy against, S. oralis, inducing an inhibition zone of 16.00 mm ± 2.82 while E. glandulosum exhibited an inhibition zone of 11.50 mm ± 0.707. These findings validate the therapeutic potential and ethnomedicinal use of these plants.

Abstract

Objective: Our study aims to explore the relations among thyroid morphology and hormones and sex, age in rhesus monkeys, so to establish a range of reference values for serological testing of thyroid hormones and thyroid ultrasonography in Chinese rhesus monkeys. Furthermore, we analyze the common diseases and incidences of abnormal thyroid morphology in these monkeys.
Methods: 1027 rhesus healthy monkeys were divided into infant, juvenile, adolescent, adult, middle-aged, and elderly groups based on their age. The thyroid hormones (TT3, TT4, FT3, FT4, TSH, A-TG, ATPO, TG) levels of each rhesus monkey were measured. Thyroid ultrasonography was performed and thyroid size, morphology, internal echogenicity, borders, presence of nodules were measured. Comparisons between groups were made by ANOVA, and comparisons within groups were made by T-test; Pearson's analysis was used to test the correlation between the two variables. We considered that α=0.05, and P<0.05 was statistically significant.
Results: The thyroid hormones tests found that there are differences in TT4, FT4, FT3, A-TG, A-TPO, and TG in different age groups (p<0.05). The differences in their FT4, FT3, A-TG, and TG were statistically significant in different genders (p<0.05), too. Thyroid ultrasound measurement of thyroid size revealed statistically significant (p<0.05) differences in their weight and thyroid LAPD, LLD, RAPD, RTD, RLD by age. There are also statistically significant (p<0.05) differences in their weight and thyroid LAPD, LLD, RLD by gender. In thyroid ultrasonography, about 14.12% of monkeys were found to have abnormal thyroid echoes, of which 71.72% were described as uneven echoes, 16.55% as grid-like changes in thyroid echoes, and 11.72% as thyroid nodules. Normal thyroid echogenicity was associated with age, body weight, TT4, TT3, FT4, FT3, and statistically significant difference (p<0.05); the rest of the group comparisons were not statistically significant (p>0.05).TT4 vs. FT4, TT3 vs. FT3, ATG vs. ATPO, body weight vs. LLD, body weight vs. RLD, LLD vs. RLD, LAPD and RAPD, and RAPD and RLD were positively correlated (p<0.05).
Conclusion: Our study provided a reference basis for quantitative analysis of thyroid hormones and morphology in monkeys through serological testing of thyroid hormones and thyroid ultrasonography. In this way, we initially established reference intervals for various hormonal indicators of thyroid hormones in Chinese rhesus monkeys of different ages and sexes, as well as reference intervals for the size of thyroid morphology by diameter under ultrasonography for different ages and sexes. We explored the types of abnormalities and prevalence of abnormalities of thyroid morphology in Chinese rhesus monkeys. The results provide basic information for scientific experimental studies on the thyroid gland of Chinese rhesus monkeys.

Abstract

The rapid urbanization in China has led to a significant increase in the generation of fly ash from municipal solid waste incineration. This has made the safe and harmless disposal of fly ash a major challenge for the waste-to-energy industry's sustainable development. The current environmental verification system lacks a complete quantitative system that integrates various evaluation indicators for solid waste resource recovery technology. Thus, there is an urgent need to expedite research on environmental technology verification (ETV) and establish an objective, fair, and scientific system for verifying and evaluating fly ash harmless disposal and resource utilization technology. In this study, an evaluation system was constructed consisting of 12 indexes from three aspects: technical characteristics, technical quality, and technical value, using the Analytic Hierarchy Process (AHP). The evaluation results were classified into three levels: recommended, suggested for improvement and optimization, and not recommended. Consequently, a comprehensive ETV system was developed. The case analysis confirmed the scientific validity and feasibility of the constructed verification system. It demonstrated that the developed verification evaluation method for the harmless disposal and resource utilization technology of fly ash can objectively and effectively evaluate the progress and applicability of the technology. Additionally, valuable suggestions for improving the technical performance were provided. Furthermore, this study provided a scientific and reliable evaluation system for fly ash harmless disposal and resource utilization technology, which is also adapted for solid waste treatment technology because of non-specific methods and concepts, and laid technical guidance for the government in studying and issuing related regulations.

Abstract

Background
Currently, numerous studies focus on the analysis of risk factors for lymph node metastasis in early gastric cancer, but few studies analyze the drainage patterns of metastatic lymph nodes.
Methods
Data was retrospectively analyzed from a database of gastric cancer resections from 2014–2018. The cohort included 786 pT1 patients with complete data. Outcomes evaluated were lymph node metastasis frequencies, survival analyses, and risk factors impacting prognosis.
Results
The overall lymph node metastasis rate was 23.7%. The 5-year overall survival rate (54.8% vs 95.7%; P < 0.001) and disease-free survival rate (48.4% vs 95.7%; P < 0.001) of patients with node-positive disease were significantly worse than those of patients with node-negative disease. Multivariable Cox regression identified tumor size > 2 cm (P = 0.007, < 0.001), poor differentiation (P = 0.007, < 0.001), T1b stage (all P < 0.001), lymph node metastasis (all P < 0.001), and vascular invasion (all P = 0.002, 0.016) as independent negative prognostic factors affecting 5-year OS and DFS in patients with early gastric cancer. Postoperative chemotherapy (P < 0.001, 0.019)was an independent positive prognostic factor.
Conclusion
This real-world observational study demonstrates that lymph node metastasis in early gastric cancer is widely and disorderly not depending on the location. Therefore, systematic lymph node dissection is necessary to cure early gastric cancer. Meanwhile its prognosis is closely related to lymph node metastasis.

Abstract

Reynoutria japonica Houtt. (Japanese knotweed) is an invasive plant belonging to the Polygonaceae family. However, being native to east Asia, it has been used in natural medicine since ages because of broad range of biological activity. Although, R. japonica is known as a rich source of phenolic compounds plant biomass collected from the field may be contaminated with toxic elements like heavy metals. Therefore, the aim of this study was to investigate biomass production and phenolic compounds synthesis in Japanese knotweed from in vitro cultures. Plants were cultivated in a traditional agar-solidified medium, in a liquid medium with rotary shaking (agitated culture), and in a temporary immersion bioreactors Plantform™, as well as in soil (ex vitro conditions). Analyses of the growth index and dry weight accumulation were performed on the collected material. In the extracts obtained from examined plants, qualitative and quantitative analysis of phenolic derivatives using DAD-HPLC was conducted to determine the sum of phenolic compounds, as well as the quantity of selected phenolic acids, catechins and other flavonoids. Results have showed that agitated cultures and temporary immersion bioreactors increased biomass accumulation compared to solid medium cultures. Tissue cultures of R. japonica had increased synthesis of phenolic compounds. Shoots and roots from agitated cultures were 2.8- and 3.3-fold richer in catechins, respectively, compared to plants from ex vitro conditions. Based on the obtained results it can be concluded that agitated and bioreactor cultures are the best source of Japanese knotweed biomass rich in valuable secondary metabolites.
A Quantum Leap Towards Sustainability? Exploring the Interplay between Green Trade Exports and Environmental Performance in OECD Countries
Authors: Choi Chang Hwan 
Published: May 2024

Abstract

The pursuit of economic growth, environmental pollution reduction, and the achievement of sustainable development are central concerns for numerous countries. In 2001, the WTO proposed the elimination of non-tariff barriers on environmental goods and services to mitigate trade barriers and reduce pollutant emissions, thereby enhancing the global trade industry chain. Several scholars have scrutinized the consequences of green trade on sustainable development. This study centers on assessing the impact of green trade exports (GTE) on green total factor productivity (GTFP) and greenhouse gas emissions, utilizing a panel dataset for OECD countries. Initially, a linear regression model is employed to observe that GTE fails to contribute to GTFP and is ineffective in mitigating CO2 emissions. The relationship between GTE and GTFP exhibits an inverted N-shaped curve. Subsequently, a non-linear threshold model is established, revealing that GTE can foster GTFP growth when clean energy and research and development (R&D) exceed the first threshold value. Consequently, an augmentation in clean energy and technological intensity can lead to sustainable development in OECD nations. This study offers vital insights for developing countries seeking to participate effectively and efficiently in the global industrial chain, thereby reducing domestic development costs.

Published: May 2024

Abstract

This research examines the dietary preferences of prey species targeted by Falco eleonorae, with a focus on analyzing isotopic signatures including δ¹³C, δ¹⁵N and δ³⁴S values. Our study uncovers significant variations in isotopic signatures among prey species, reflecting their distinct trophic levels and geographical origins. The δ¹³C values of European storm petrel notably is associated with marine sources. Conversely, the spotted flycatcher exhibits unexpectidely high δ¹³C and δ¹⁵N values, warranting further investigation into its dietary habits. Interestingly, the European greenfinch demonstrates fluctuations in intrafeather amplitude during molting season suggesting dietary shift despite its primarily granivorous nature. While some prey species align with existing literature, caution is advised in generalizing these findings due to sample size limitations. The acquisition of a substantial sample size is imperative for discerning subtle variations and thoroughly examining stable isotope signatures, thereby enhancing our understanding of prey dietary patterns. Consequently, this study underscores the necessity of further robust analysis to attain a nuanced comprehension of ecological dynamics within avian community.

Abstract

Aims
Rice yields are significantly influenced by both biotic and abiotic factors, like drought stress and weed infestation being prominent contributors to substantial crop losses. Environmental conditions, including drought stress, can impact the effectiveness of herbicides. The aim of this study is to investigate the impact of drought stress on the efficacy of the herbicide (Cyhalofop + Penoxsulam) against the weed species, Echinochloa colona (L.) Link, and Alternanthera paronychioides A. St.-Hil. Additionally, the study aims to assess the potential consequences of improper weed control, including the survival of weeds and their subsequent adverse effects on rice.
Methods
The herbicide was applied to rice plants under two distinct conditions: well-watered (WW) and drought-stressed (DS) at 8 days following the suspension of irrigation. The herbicide's effectiveness against two weed species, E. colona and A. paronychioides, assessed by quantifying weed growth and biomass.
Results
The findings elucidate a reduction in the herbicide efficacy against both the weeds under DS conditions. However, under DS the decline in herbicide effectiveness was more significant against E. colona than A. paronychioides, leading to inadequate weed control. As a result, the survival of these weeds further exacerbating oxidative stress in rice plants. The magnitude of oxidative stress was excess in rice with E. colona than A. paronychioides, and it significantly reduced the yield under both WW and DS.
Conclusions
The study highlighted that under drought conditions rice is more susceptible to E. colona infestation than to A. paronychioides with increased oxidative stress and reduced yield.

Published: May 2024

Abstract

Identifying protein complexes from protein-protein interaction networks is one of the crucial tasks in computational biology. Traditional methods, along with their shortcomings in fully understanding protein complex composition, also have inherent limitations and are expensive to implement. In this paper, we introduce a novel method that not only acknowledges but actively tackles these challenges. Our approach, centered around a core-attachment framework, employs a blend of topological metrics, such as square clustering coefficients, in conjunction with traditional clustering coefficients. After establishing the core, we incorporate attachment proteins based on specific conditions employing a based depth-first approach to form a protein complex. By harnessing multiple metrics, our goal is to elevate the accuracy of protein complex identification beyond what single-metric approaches can achieve.

To validate the effectiveness of our approach, we conducted extensive experiments using multiple datasets, including Gavin06, Krogan core, Krogan extend, and DIP datasets, and assessed metrics such as precision, recall, F-measure, and coverage. Our results not only demonstrate the superiority of our method over traditional approaches but also align with findings from related studies.
Overall, our study contributes to the ongoing efforts in computational biology by presenting a comprehensive approach to protein complex identification that addresses the shortcomings of previous methods. Through a combination of innovative techniques and insights from recent research, we aim to push the boundaries of accuracy and comprehensiveness in protein complex detection.
