Published: September 2023

Arterial hypertension is considered a risk factor for the development of heart failure. Here we investigate cross-sectional associations of systolic and diastolic blood pressure with subtle functional and morphological changes of left ventricular echocardiographic parameters representing early dysfunction in three representative German population-based studies. We assessed 26,719 individuals without symptomatic heart failure from the Hamburg City Health Study (HCHS, n = 7396, derivation cohort), the Gutenberg Health Study (GHS, 14,715, validation cohort) and the Study of Health in Pomerania (SHIP, 4608, validation cohort). Multivariable linear regression analyses with systolic and diastolic blood pressure as continuous exposure variables were adjusted for common cardiovascular risk factors and antihypertensive medication. Both systolic and diastolic blood pressure were consistently associated with measures of left ventricular hypertrophy (β per standard deviation (SD) for LV mass (g) and systolic blood pressure: 5.09 (p < 0.001); diastolic blood pressure: 2.29 (p < 0.001) in HCHS). Systolic blood pressure correlated with declining diastolic function (β per SD for E/e′: 0.29, p < 0.001 in HCHS) and diastolic blood pressure with declining systolic function (β per SD for LVEF, in %: − 0.15; p = 0.041 in HCHS) in all cohorts. Pending further validation, our results from three independent German population samples suggest differential effects of systolic versus diastolic blood pressure on left ventricular structure and function.
Biodegradable nano-reinforced packaging with improved functionality to extend the freshness and longevity of Plums Oemleria cerasiformis
Authors: Mann Manpreet Kaur , Sooch Balwinder Singh
Published: September 2023

Food packaging reinforced with Zn-doped TiO2 nanoparticles with enhanced prerequisite film-forming and biodegradable traits was prepared to augment fresh food storage. Pure and tailored metal (Zinc, Copper, and Selenium) doped TiO2 nanoparticles were synthesized and analyzed through multiple characterization techniques (optical spectra, XRD patterns (X-Ray Diffraction), Dynamic Light Scattering, and Scanning Electron Microscopy). The synthesized nanoparticles were tested for their Minimum Inhibitory Concentrations, antimicrobial potential against common lethal food pathogens, and cytotoxicity. Compared to Cu- and Se-doped nanoparticles, Zn-doped TiO2 nanoparticles displayed the most potent antimicrobial activity with insignificant cytotoxicity and were incorporated into the food packaging materials. The developed nano-reinforced food packaging efficaciously augmented the freshness of plums (Oemleria cerasiformis) for 16 days (42 ± 2 °C). The physicomechanical characterization of the nano-reinforced packaging establishes its utility in food packaging applications. The developed biodegradable packaging undergoes complete decomposition within 12 days of storage in natural soil.
Influencing factors in the stagnation of the Baiu front that induced heavy rainfall in July 2020 over Kyushu, Japan
Authors: Moteki Qoosaku
Published: September 2023

The influencing factors of the long-term stagnation of the Baiu front that induced heavy rainfall in July 2020 over Kyushu, Japan, were examined. In July 2020, the position of the Baiu front from a weather chart at 130° E remained stationary over Kyushu for 20 days, and that was the longest from 2002 to 2021. By examining a certain index of the Yellow Sea High (YSH), which is a necessary condition for Baiu front stagnation near Kyushu, it was confirmed that in 2020, a positive high-pressure anomaly persisted over the Yellow Sea until the end of July. The YSH maintenance was due to the significant negative sea surface temperature (SST) anomaly over the Yellow Sea. The significant negative SST anomalies in the Yellow Sea were due to vertical mixing in ocean mixed layer in response to the strong winds of the extratropical cyclones. A rapid SST decrease ranging from 0.5 to 1.5 °C/day was repeatedly occurred by ocean mixed layer deepening in association with the passage of the extratropical cyclones. The anomalous long-term stagnation of YSH due to the negative SST anomalies could have caused the Baiu front to remain stagnant over Kyushu until the end of July.
Stability of the personal relationship networks in a longitudinal study of middle school students
Authors: Escribano Diego , Lapuente Francisco J. , Cuesta José A. , Dunbar Robin I. M. , Sánchez Angel
Published: September 2023

The personal network of relationships is structured in circles of friendships, that go from the most intense relationships to the least intense ones. While this is a well established result, little is known about the stability of those circles and their evolution in time. To shed light on this issue, we study the temporal evolution of friendships among teenagers during two consecutive academic years by means of a survey administered on five occasions. We show that the first two circles, best friends and friends, can be clearly observed in the survey but also that being in one or the other leads to more or less stable relationships. We find that being in the same class is one of the key drivers of friendship evolution. We also observe an almost constant degree of reciprocity in the relationships, around 60%, a percentage influenced both by being in the same class and by gender homophily. Not only do our results confirm the mounting evidence supporting the circle structure of human social networks, but they also show that these structures persist in time despite the turnover of individual relationships—a fact that may prove particularly useful for understanding the social environment in middle schools.

Authors: Ganasen Nakkeeran , Krishnaraj L. , Onyelowe Kennedy C. , Alaneme George Uwadiegwu , Otu Obeten Nicholas
Published: September 2023

In this study, the replacement of raw rice husk, fly ash, and hydrated lime for fine aggregate and cement was evaluated in making raw rice husk-concrete brick. This study optimizes compressive strength, water absorption, and dry density of concrete brick containing recycled aggregates via Response Surface Methodology. The optimized model's accuracy is validated through Artificial Neural Network and Multiple Linear Regression. The Artificial Neural Network model captured the 100 data's variability from RSM optimization as indicated by the high R threshold- (R > 0.9997), (R > 0.99993), (R > 0.99997). Multiple Linear Regression model captured the data's variability the decent R2 threshold confirming- (R2 > 0.9855), (R2 > 0.9768), (R2 > 0.9155). The raw rice husk-concrete brick 28-day compressive strength, water absorption, and density prediction were more accurate when using Response Surface Methodology and Artificial Neural Network compared to Multiple Linear Regression. Lower MAE and RMSE, coupled with higher R2 values, unequivocally indicate the model's superior performance. Additionally, employing sensitivity analysis, the influence of the six input parameters on outcomes was assessed. Machine learning aids efficient prediction of concrete's mechanical properties, conserving time, labor, and resources in civil engineering.
Identification and classification of ATS in oral fluid based on Ag nanoassemblies on Si surface doped with Au nanobipyramids
Authors: Cui Sheng-Feng , Yang Hai-Long , Huang Xin , Wan Jing-Wei
Published: September 2023

Herein, a novel Ag NP substrate doped with Au nanobipyramids was designed and fabricated via a convenient procedure of galvanic reaction for the identification and classification of amphetamine-type stimulants (ATS) in oral fluids in combination with surface enhanced Raman scattering (SERS). The substrate was shown to have a three-dimensional nanostructure, high SERS activity, and good stability. In combination with SERS, the Ag NP substrate doped with Au nanobipyramids was able to detect ultra-low traces of ATS, including amphetamine, methylamphetamine (MA), 3,4-methylenedioxyamphetamine (MDA), and 3,4-methylenedioxymethylamphetamine (MDMA) in oral fluid with limit of detection (LOD) and limit of determination quantitation (LOQ) as low as 10–9 mg/mL, which is much better than the current spectroscopic techniques. The equations between concentration and peaks intensity for quantitative analysis displied good doublelogarithmic linear relations and reliability figures of merit at nanogram concentration level in compartion with GC–MS method. The approach can be broadly applied to the ultra-low trace detection of ATS in oral fluid and would be particularly useful for the analyses of nitrogenous organic compounds.

Published: September 2023

Human T-lymphotropic virus (HTLV) infection has a worldwide distribution and currently, more than 2.5 million individuals have been infected in Brazil. The study aimed to investigate HTLV infection prevalence among blood donors in Mato Grosso do Sul, characterizing seroepidemiological profiles of HTLV-1/2 positive individuals and evaluating the blood bank's HTLV screening system. A cross-sectional survey was conducted among blood donors from Mato Grosso do Sul state (MS)—Central Brazil, between January to December 2021. The information was obtained from databases, samples from the collection of HEMOSUL, and active searching, with the completion of laboratory analyses. 35,278 blood donors were screened for anti-HTLV-1/2 by chemiluminescence immunoassay (CMIA). Among them, 78 were initially reactive for anti-HTLV-1/2 (2.21/1000). Out of 78, 67 returned to the blood center to collect a second sample for retesting with a second screening with CMIA. After confirmation, 8 samples were indeterminate, and 8 were confirmed as positive for HTLV antibodies. New tests were performed for the 8 positive samples, and 6 were confirmed as HTLV-1 infection (0.17/1,000), one as negative, and one as indeterminate. The present study describes the low prevalence of HTLV infection in blood donors from MS and contributes to the definition of the regional infection profile. The prevalence found in this study (0.017%–0.17/1000) shows to be a much lower value than the rates reported in other states in Brazil. We highlight the need for confirmatory testing for those seropositive donors in screening assays and the need for adequate counseling and patient management for those confirmed HTLV individuals.
Andean-type orogenic plateau as a trigger for aridification in the arcs of northeast Pangaea
Authors: Song Dongfang , Mitchell Ross N. , Xiao Wenjiao , Mao Qigui , Wan Bo , Ao Songjian
Published: September 2023

The interplay between continental motions during the assembly of Pangaea and late Palaeozoic climate change, including severe glaciation and global aridification, remains enigmatic. Here we identify the provenance of Permian–Early Triassic sediments that recorded climate change of North China and estimate palaeoelevation to constrain tectonic-climate interaction during the assembly of northeast Pangaea. Detrital zircon U-Pb-Hf analysis indicates the sediments were locally sourced from the ancient basement and associated with a late Palaeozoic (410–260 million years ago) continental arc, devoid of input from juvenile arcs of the Altaids. These sediments were interpreted as deposited in a retroarc foreland basin ascribed to subduction of the Palaeo-Asian Ocean. Crustal thickness estimated from whole-rock La/Yb yields an average value of 58 ± 11 km, which corresponds to a palaeoelevation of 3.8 ± 0.7 km. The results reveal the existence in North China of an orogenic plateau comparable to the Altiplano of the Andes that blocked moisture transport from the ocean and served as an important orographic barrier to trigger Permian aridification.
Transdifferentiation of cervical squamous cell carcinoma with ERBB2 amplification to adenocarcinoma: whole genome sequence analysis and successful control by anti-HER2 therapy

Published: September 2023

Cancer cells sometimes transdifferentiate into different histological type(s) and tumors with multiple histological types can share a common ancestor cell. However, diagnosis of the origin of multiple tumor lesions with different histological features remains a clinical challenge. A 45-year-old woman with a history of cervical squamous cell carcinoma (CeSq) presented with abdominal pain and vomiting. A surgical operation revealed an ileal tumor and a peritoneal nodule with a small amount of ascites. A histological examination of the ileal tumor demonstrated squamous cell carcinoma, which was consistent with metastasis of cervical cancer, while that of the nodule and ascites showed adenocarcinoma. Whole genome sequencing (WGS) of the CeSq, ileal squamous cell carcinoma (SiSq), and peritoneal adenocarcinoma (PeAd) demonstrated that ERBB2 was commonly amplified in all lesions. Additionally, HPV-16 genome sequences were identified at identical genomic loci in these lesions. A trajectory analysis corroborated that SiSq and PeAd had a shared origin and developed simultaneously at each metastatic site. These results indicate that a subpopulation of the CeSq had transdifferentiated into adenocarcinoma in our patient. Anti-HER2 therapy showed marked effects on the recurrent disease. Our case demonstrates the plasticity of tumor cells and reinforces the potential roles of WGS in the implementation of precision oncology.

Under given framework conditions, three pathways comprising the entire energy system were investigated in 5‐year time steps and hourly resolution applying an advanced energy system modelling tool and identifying the lowest cost solutions. The British Isles were structured into 10 sub‐national regions. Special attention was paid to the high offshore wind potential of the British Isles, as well as the limited societal acceptance for onshore wind in the United Kingdom. The results indicate that a transition to 100% renewable energy is economically more attractive than the governmental strategy that involves nuclear power and fossil carbon capture and storage. The total annualised system costs can decrease to 63 b€ and a levelised cost of electricity of 40 €/MWh if onshore wind and solar photovoltaics are allowed to be built to a higher extend. High levels of electrification and sector coupling are the main reasons for decreasing primary energy demand. The multiple risks of nuclear technology can be avoided if dedicated action towards 100% renewable energy is taken.
Pseudo conditional distribution induced radio source localisation using received signal strength measurements
Authors: Zhang Donglin , Duan Zhansheng
Published: September 2023

In received signal strength (RSS) based radio source localisation, RSS measurements can be converted to the squared distance estimates between the emission source and the sensors to construct a system of pseudolinear equations, allowing for the use of the weighted linear least squares (WLLS) estimators for location estimation. The WLLS estimators are widely applied in practice because of their simplicity and computational efficiency. Nevertheless, the major challenge of this approach lies in estimating the squared distance from RSS measurements governed by the log‐normal shadowing effect. A pseudo conditional distribution (PCD) of the squared distance between the emission source and the sensor is introduced first, given the RSS measurement at each sensor. Then, the authors propose a series of new WLLS location estimators, using three typical statistical characteristics, that is, mean, median, and mode, of the PCD. Analysis of their estimation performance are also provided through performance rankings in terms of their mean square errors and covariances. It is found that estimation performance of the PCD‐induced WLLS estimators heavily depends on the choice of the statistical characteristic of the PCD and different choices lead to estimators with better, worse, or equal performance. Numerical examples show that the proposed mode‐WLLS estimator always performs better than the existing WLLS estimators, and also better than the existing convex optimisation based algorithms in most cases but with much less computations.

We present the analysis of multiepoch observations of a set of 12 variable, Compton-thin, local (z < 0.1) active galactic nuclei (AGN) selected from the 100-month BAT catalog. We analyzed all available X-ray data from Chandra, XMM-Newton, and NuSTAR, adding up to a total of 53 individual observations. This corresponds to between three and seven observations per source, probing variability timescales between a few days and ∼20 yr. All sources have at least one NuSTAR observation, ensuring high-energy coverage, which allowed us to disentangle the line-of-sight and reflection components in the X-ray spectra. For each source, we modeled all available spectra simultaneously, using the physical torus models MYTorus, borus02, and UXCLUMPY. The simultaneous fitting, along with the high-energy coverage, allowed us to place tight constraints on torus parameters such as the torus covering factor, inclination angle, and torus average column density. We also estimated the line-of-sight column density (NH) for each individual observation. Within the 12 sources, we detected clear line-of-sight NH variability in five of them, non-variability in five of them, and for two of them it was not possible to fully disentangle intrinsic luminosity and NH variability. We observed large differences between the average values of line-of-sight NH (or NH of the obscurer) and the average NH of the torus (or NH of the reflector), for each source, by a factor between ∼2 to > 100. This behavior, which suggests a physical disconnect between the absorber and the reflector, is more extreme in sources that present NH variability. We note that NH-variable AGN also tend to present larger obscuration and broader cloud distributions than their non-variable counterparts. These trends however require a larger number of sources to confirm (or disprove) this. We observed that large changes in obscuration only occur at long timescales, and used this to place tentative lower limits on torus cloud sizes. Furthermore, we observed a median variation in NH between any two observations of the same source of ∼36%.

There are conflicting views among researchers on the precise beginning of champignon cultivation. While some contend that its cultivation began in France, others assert that it originated in Italy around a thousand years ago. French farmers discovered in the 17th century that champignons thrived not just on manure-fertilized lawns but also in dark, damp quarters, a method that is still used today. Champignon was cultivated on dedicated farms on royal estates when European kings ruled the continent because it was a costly and uncommon delicacy. The objective of this study was to analyze the composition of the common mushroom using mass spectrometry with a Chromatek-Crystal 5000 spectrometer. The study aimed to extract and quantitatively determine the compounds present in the common fungus. A technology for obtaining the drug was developed through experiments, which involved extracting plant materials with absolute alcohol. The methodology employed can be used to further explore the properties of the common mushroom, and contribute to the development of effective pharmaceutical products.

According to the research and observations, the pest damage of peanut varieties planted in the experimental field of the institute was different. Peanut oil is used in all areas of the national economy for the preparation of food, canning, varnish, soap, linoleum, perfumery, printing ink, medicine, and vegetable oil or animal fat. Oilseeds are not limited to obtaining oil, their pulp is a nutritious feed for livestock and a raw material for the processing industry. Compared to other crops (wheat, corn), oilseeds contain protein (45-50%) and oil (25-30%), and their total amount is on average 70-80%. In the article, 24 species of pests specialized in soybeans and peanuts were observed. Among the encountered pests, 8 types of pests with high economic damage were identified. These include Setona sylindricollis Fahr, Callosebruchus maculates Z, Acyrthosiphon onobrychis Fonse, Adelphocoris lineolatus Goes, Liriomysa cicerina Rond, Odontothrips intermedins Uzel, Cicadella virdis L, and Heliothis armigera Hb. Moreover, 6 types of pests, namely, Dociostaurus maroccanus Thunb, Setona cylindricollis Fahr, Sitona lineellus Bansd, Adelphocoris lineolatus Goes, Heliothis armigera Hb, and Agrotis segetum Schiff, were observed in soybean and peanut crops.

Fungal contamination in vegetable crop seeds poses a significant threat to agricultural productivity and food security. This manuscript investigates the presence of fungi in the main vegetable crop seeds and explores their fungal biological characteristics. The study employed a comprehensive approach involving sample collection, fungal isolation, morphological identification, and molecular characterization. The research collected a diverse range of vegetable crop seeds from different locations of Uzbekistan and examined them for the presence of fungal pathogens. Aseptic techniques were utilized to isolate and culture fungi from the seed samples. Morphological characteristics, including colony appearance, spore production, and hyphal structure, were evaluated to identify the fungal species. In cases where morphological identification was challenging, molecular techniques were employed for accurate species determination. The research of 36 species of fungal phytotoxic qualities was done using seeds that were collected and preserved during the growing of vegetable crops in farms in the Tashkent region of Uzbekistan. The findings are presented in this paper. Based on the impact on vegetable crop root and stem growth and seed germination, phytotoxic characteristics were identified. Phytotoxic fungi were defined as those that lowered these markers by 30% when compared to the control.

It is promising to grow the long-vegetating annual halophytesGamanthus BungeandHalimocnemis C.A. Mey. (Chenopodiaceae Vent.) in arid locations since they are important grazing plants for Karakol sheep and camels. These species’ xerothermic periods are when they flower and bear fruit. Research on reproductive biology must first examine how certain traits of plant reproductive organs in harsh environments relate to environmental influences. Identification of reproductive organ adaptation to air temperature and water stress in desert plants is an issue that has not received much attention fromChenopodiaceaefamily members. Such knowledge is crucial for developing perennial agrophytocenoses and boosting the production of pastures in need. The study ofHalimocnemisspecies is particularly interesting since this genus is thought to be confined to the Iran-Turonian floristic zones, with the Central Asian (Turonian) plains being its center of origin. In the studied species, there are signs that ensure the xenogamous type of pollination by entomophilia. These are proterandria in flowers, brightly colored outgrowths of pollen which are secondary attractants, morning type of flowering when insects are in high flight, and autogamous type of pollination by anemophily. Similar conditions eventually lead to funneling ofHalimocnemisandG. gamocarpus.

The most pervasive and harmful illness is cruciferous black spot disease. This disease starts to show symptoms as soon as the seed emerges from the soil and continues all through the growth season. In regions designated for seeds, cabbages left for storage, and areas planted for human consumption, the disease is seen. The illness Alternaria mostly affects the cruciferous plants’ organs responsible for generating seeds, and it severely damages the pods and seeds. The leaves and bulbs of crucifers are less impacted. Every region that grows cruciferous vegetable crops has Alternaria disease. In this article, the spread and development of alternaria disease in cruciferous vegetable crops (cabbage, cauliflower, broccoli, red cabbage, collard, Napa cabbage) and its damage by the fungus A. brassicae, which causes alternaria disease, and damage by alternaria disease and its causative agent, were determined. Due to the Alternaria disease, the yield loss of all vegetable crops was observed. Compared to a healthy plant, the loss of 14.3-17.4% of the yield of cabbage, followed by cauliflower - 8.3-12.1%, red cabbage - 10.0%, Napa cabbage - 10.0-12.2% and, broccoli 10.2-16.0% was reported.
