Authors: Olimovna Oripova Ozoda ,   Samarkand State Medical University, Samarkand, Uzbekistan
Published: July 2024

Effects of alcohol metabolites, mainly acetaldehyde, on the heart. Disturbances in metabolism and electrolyte imbalance lead to arrhythmias and disturbances in the functional activity of the heart. Acetaldehyde disrupts the synthesis of several compounds and increases the synthesis of inflammatory cytokines and leads to the development of an autoimmune process. The weight of the heart is 500-550 gr. and it is observed that it is filled with fat. When the heart is placed on the operating table, it is diffuse, similar to infectious myocarditis, and the heart is red or purple in color.

Welding production is used in a wide range of industries, including construction, automotive manufacturing, shipbuilding, aerospace, and more. It is a crucial process in creating strong and durable structures and products. Welding is a fabrication process whereby two or more parts are fused together by means of heat, pressure or both forming a join as the parts cool. The completed welded joint may be referred to as a weldment. Failure of a welded junction happens when it does not satisfy expected strength standards or does not serve the purpose for which it was designed. A number of things, such as improper welding technique, the wrong choice of material, the wrong welding procedure, or subpar quality control during the production process, can lead to welding joint failure. Experimental tests for quality assurance and inspections were applied in aid for spotting potential problems and preventing welding joint failure. The weldments were studied for tensile test and impact test. The research provides discussion on the SolidWorks simulation method on different steel material in terms of quality welding joint. The objective of this study is to investigate the relationship between two types of welding which are MIG and TIG welding and different steel materials involving low carbon steel (LCS), cold-rolled steel (CRS) and hot-rolled steel (HRS) through SolidWorks simulation. The main focus of this study was to propose the best welding joint design with minimal welding defects, for instances, porosity, weld cracks and undercut. This study was designed in order to find out about the performances of various welding types on different steel materials castings in welding production. There were three different weld joint designs proposed in this study based on the previous researches with fixed parameters installed on each design.

Development of rice genotypes possessing high yielding potential; with increased grain iron content is the need of the hour to tackle hidden hunger. Considering the above said fact, genetical analysis was conducted in six improved cultivars along with 15 potential crosses thereof. Analysis of variance for combining ability revealed significant differences in GCA and SCA variances for grain yield as well as for iron and zinc content, indicating the possibility of realization of development of iron fortified varieties with higher yielding potential. The preponderance of additive gene action for these two important characters i.e., iron and zinc content indicate that selection will be highly rewarding for genetic improvement pertaining to these two traits. The genotype Gouri was found to be very good combiner for both grain yield (0.93) and iron content of grain (2.04). Similarly, genotype Sebati was found as a very good combiner for both grain yield (0.13) and zinc content of grain (0.65). Some of the superior crosses identified concerning both grain yield and grain iron content were Birupa / Pradeep, Sebati / Gouri, Sebati / Pratap, Gouri / Pradeep and Pratap / Pradeep. Hence, these specific crosses can be used in further breeding programme for the improvement of both grain yield as well as grain iron content. The crosses viz., Bhanja / Pratap and Bhanja / Sebati were found to be superior crosses for both grain yield and grain zinc content.
Decentralized Algae Removal Technologies for Lake Diefenbaker Irrigation Canals: A Review

Lake Diefenbaker Irrigation Canals in Canada are crucial in providing water for irrigation, preventing droughts and floods, and supporting the Saskatchewan agriculture industry and economy. Unfortunately, filamentous algal blooms occur every summer in Lake Diefenbaker Irrigation Canals. These algae are not toxic but a nuisance. They block farmers’ pumps and reduce irrigation water flow rates. Currently, the Water Security Agency periodically adds the algaecide Magnacide H. to control the algal blooms, which is costly (i.e., one million dollars per year for the Lake Diefenbaker M1 Irrigation Canal only) and requires effort to dewater the canal to protect fish. Therefore, algae removal before the canal water enters farmer’s pumps might be a cost-effective alternative, especially the removal of microalgae during the initial stages of growth in June of each year. This paper has summarized and evaluated algae removal technologies, considering their advantages, disadvantages, and potential solutions for addressing the challenges and limitations associated with these technologies. Five algae removal technologies were identified as promising, which are suspended air flotation (SAF), dissolved air flotation (DAF), hydrodynamic cavitation, spiral blade centrifuge, and coagulation. Among them, SAF seems the most suitable option, while DAF and hydrodynamic cavitation offer eco-friendly advantages. Further research and pilot testing are needed to determine the costeffective and feasible algae removal technology for Lake Diefenbaker Irrigation Canals.
Epigenetics and Rheumatoid Arthritis: Decoding the Interplay
Authors: Hasan Ahmar , Ziaur Rahman Syed
Published: July 2024

Rheumatoid arthritis, or RA, is a type of chronic inflammatory disorder that is defined by inflammation of the joints, pain, and joint degeneration. Thus, although genetic predispositions play a role in RA development, they are insufficient to explain differences in the disease’s initiation and activity. Epigenomics, referring to changes in the phenotype of a gene or group of genes brought by modification of the DNA molecule without altering its base sequence, offers important information on RA’s multifactorial etiology. The present article aimed at discussing the various epigenetic features in RA such as DNA methylation, histone modification, and non-coding RNA. These changes include, hypomethylation of the pro-inflammatory genes and hypermethylation of the anti-inflammatory genes and this promotes inflammation in the body specifically in RA. Other epigenetic abnormalities causing distortion of disease pathology include dysregulated histone modifications and non-coding RNAs. Knowledge of these epigenetic changes have brought about the intervention strategies in the form of epigenetic therapies. Azacitidine, vorinostat and miRNA based therapies are some of the classes of drugs which demonstrate efficacy in preclinical and clinical trials. That nevertheless there are some limitations that researchers are yet to embrace regarding specificity, delivery, and the true interactions between epigenetics. It is proposed that the further research should be concentrated on the development of precise or pharmacogenomic medicine approaches, the combination of genetic and epigenetic aspects of the drug treatment. In this context, the present review of the epigenetic targets and therapies clearly brings out the possibilities of im-proving RA management and the quality of life of patients through epigenetic interventions.

Most stars are born in stellar clusters, and their protoplanetary disks, which are the birthplaces of planets, can, therefore, be affected by the radiation of nearby massive stars. However, little is known about the chemistry of externally irradiated disks, including whether or not their properties are similar to the so-far better-studied isolated disks. Motivated by this question, we present ALMA Band 6 observations of two irradiated Class II protoplanetary disks in the outskirts of the Orion Nebula Cluster to explore the chemical composition of disks exposed to (external) far-ultraviolet (FUV) radiation fields: the 216-0939 disk and the binary system 253-1536A/B, which are exposed to radiation fields of 102–103 times the average interstellar radiation field. We detect lines from CO isotopologues, HCN, H2CO, and C2H toward both protoplanetary disks. Based on the observed disk-integrated line fluxes and flux ratios, we do not find significant differences between isolated and irradiated disks. The observed differences seem to be more closely related to the different stellar masses than to the external radiation field. This suggests that these disks are far enough away from the massive Trapezium stars, that their chemistry is no longer affected by external FUV radiation. Additional observations toward lower-mass disks and disks closer to the massive Trapezium stars are required to elucidate the level of external radiation required to make an impact on the chemistry of planet formation in different kinds of disks.
The Jittering Jets Explosion Mechanism in Electron Capture Supernovae

⊙ toward core collapse by electron capture and find that the convective zone of the precollapse core can supply the required stochastic angular momentum fluctuations to set a jet-driven electron capture supernova explosion in the frame of the jittering jets explosion mechanism. By our assumed criteria of a minimum convective specific angular momentum and an accreted mass during jet launching of M

Depending on the model, this exploding layer is accreted at about a minute to a few hours after core collapse occurs, much shorter than the time the exploding shock crosses the star. The final (gravitational) mass of the neutron star (NS) remnant is in the range of M

Published: July 2024

Comets are frozen remnants of our solar system’s formation, and comparing their chemical composition to that of planet-forming systems can reveal crucial insights about our origins, potentially answering one of the most challenging questions in planetary science, i.e., whether cometary material was mainly inherited from the protosolar nebula or reprocessed during the solar system formation. Here we provide the first statistical analysis of methanol, formaldehyde, and ammonia abundances in 35 comets and 11 protostellar solar analogs and planet-forming disks. We show that comets from different dynamical families have comparable compositions on average, implying that their chemistry is preserved even after formation. While abundances retrieved from infrared and (sub)millimeter ground-based observations are in agreement, there are significant differences with those obtained via mass spectroscopy for 67P/Churyumov–Gerasimenko, target of the ESA-Rosetta mission; we discuss the implication of relying solely on the latter data for comparisons with disk abundance ratios. Finally, we find a significant difference in the [CH3OH]/[H2CO] ratio in comets observed within or farther than 1 au from the Sun, suggesting that temperature-activated mechanisms can enhance the H2CO production in the coma; this bias can strongly influence our understanding of comet chemistry in the context of planet formation. When compared to planet-forming systems, the [CH3OH]/[H2CO] and [NH3]/[CH3OH] molecular abundance ratios in comets are consistent with those measured in Class 0 hot corinos and in the inner regions of Class II disks, hence suggesting an inheritance scenario.

Published: July 2024

A comprehensive infrared spectroscopic study of star TRAPPIST-1 is a crucial step toward the detailed examination of its planets. While the presence of Earth’s atmosphere has limited the spectral extent of such a study up to now, the Near Infrared Imager and Slitless Spectrograph (NIRISS) and the Near Infrared Spectrograph instruments aboard the James Webb Space Telescope (JWST) can now yield the 0.6–5 μm spectral energy distribution (SED) of the star. Here we translate TRAPPIST-1's SED into tight constraints on its luminosity (L
bol = 0.000566 ± 0.000022 L
⊙), effective temperature (T
eff = 2569 ± 28 K), and metallicity ([Fe/H] = 0.052 ± 0.073) and investigate the behavior of its gravity-sensitive indices. Through band-by-band comparisons of the NIRISS and ground-based spectra, TRAPPIST-1 exhibits a blend of both field source and intermediate-gravity spectral characteristics, suggesting that the star is likely a field-age source with spectral features reminiscent of young objects. We also employ photospheric modeling incorporating theoretical and JWST spectra to constrain stellar surface heterogeneities, finding that the limited fidelity of current stellar spectral models precludes definitive constraints on the physical parameters of the distinct spectral components giving rise to TRAPPIST-1's photospheric heterogeneity and variability. In addition, we find intermodel differences in the inferences of properties (e.g., the effective temperature) over one order of magnitude larger than the instrument-driven uncertainties (∼100 K vs. ∼4 K), pointing toward a model-driven accuracy wall. Our findings call for a new generation of stellar models to support the optimal mining of JWST data and further constraining stellar—and ultimately planetary—properties.

Introduction: Cutaneous leishmaniasis (CL) is one of the neglected tropical diseases that affects impoverished communities throughout the world. In Pakistan CL is an endemic disease.
Aims and objectives: This study aimed to determine the incidence of CL infection in the Baluchistan province of Pakistan from January 2020 to March 2022 during the COVID-19 pandemic.
Methodology: A total of 1047 clinically suspected cases of CL from Bolan Medical College Hospital, Quetta, were followed up in the study. The data regarding the epidemiological characterstics, pathological information, and treatment of patients was collected.
Results: Out of 1047 probable cases of CL, 594 (56.73%) cases were found to be positive for CL. Females had the highest infection rate, with the majority of reported cases being in the 0–9-year age group. Most CL cases were reported in April in the year 2020, with a few cases reported in June. But in the year 2021, the highest number of cases were reported in December. The number of overall cases has gradually increased in the year 2022, most likely because of the reduction in COVID-19 pandemic restrictions. The p value for the positive as compared to suspected cases in the years 2020, 2021, and 2022 was calculated as 0.8925, 0.8763, and 0.8535 respectively.
Conclusion: Further epidemiological studies and health education campaigns are recommended to increase public awareness. It is strongly advised that local, provincial, and national health authorities establish and maintain effective leishmaniasis surveillance systems to promptly identify disease outbreaks and implement timely control measures.
A Case of Klebsiella pneumoniae infection
Authors: Liu Xuefang , Yu Ning , Lu Huaihai , Zhao Yinlong , Zhu Junyu , Liu Ya
Published: July 2024

Introduction: In recent years, hypervirulent Klebsiella pneumoniae (hvKp) has attracted increasing attention. It usually causes liver abscesses, which spread through the bloodstream to other parts such as the eyes, brain, lungs. 5.5% of all paroxysmal sympathetic hyperactivity syndrome are associated with infection, hydrocephalus, brain tumors, and some unknown causes. Younger patients with focal lesions of the brain parenchyma are at higher risk of paroxysmal sympathetic hyperactivity (PSH).
Case presentation: This case report details the clinical features of Klebsiella pneumoniae diagnosed in a healthy individual. In addition to liver abscesses, bacteremia, and hyperglycemia, there are also brain abscesses, hernias, and postoperative paroxysmal sympathetic hyperactivity, an unexpected association between diseases or symptoms. The patient stabilized after comprehensive treatment, including early drainage of abscesses, rapid pathogen diagnosis, and timely and appropriate antibiotics. At a two-month follow-up, no signs of infection recurrence were noted, and the patient regained neurological function and could participate in regular physical activity.
Discussion: Symptoms of Klebsiella pneumoniae infection usually appear gradually, and misdiagnosis is common. When young patients suddenly develop high fever and abscess at a particular site, Klebsiella pneumoniae infection should be considered routine. Paroxysmal sympathetic hyperactivity syndrome caused by infection is rare, but a clinical score (PSH assessment measure, PSH-AM score) should be performed when clinical features appear. Early diagnosis and treatment can improve the prognosis.
Phenological gap in fruiting period and dispersal of seeds from alien fleshy-fruited plants by medium-sized carnivores in temperate forests of Central Europe
Authors: Kurek Przemysław , Wiatrowska Blanka , Piechnik Łukasz , Holeksa Jan
Published: July 2024

Some biological differences between native and alien plants are relevant to their dispersal mechanisms. One of them is the fruiting period: it is shifted in time, peaking later than in natives. Here we report the case study showing the temporal distance in fruiting phenology between native and alien plants and their seed dispersal via carnivorous mammals. From 2009 to 2011, scats of badgers Meles meles, foxes Vulpes vulpes, martens Martes spp. (M. martes and M. foina) and possibly also raccoon dogs Nyctereutes procyonoides (N = 820) were collected along transects totaling 30.4 km in length each month from June to November. We analyzed the frequency of occurrence of seeds (FO%) and the seed load in sampled scats; 61.7% of the sampled feces contained seeds of 18 fleshy-fruited native and alien plant taxa, and the most abundant seeds were from species with multi-seeded fruits such as Vaccinium myrtillus (94.6%), Rubus sp. (2.0%), and drupes of Prunus serotina (1.0%). The structure of dominance was characterized by seeds of Vaccinium myrtillus (15.0%), Pyrus sp. (14.8%) and Prunus serotina (13.0%) with aliens reaching high frequency of occurrence (FO%). The shares of seed FO% in the samples differed between alien and native plants. For seed load there were also significant interactions between the status of the seeds (alien or native) and the month of the vegetation period. Our data show the coincidence of two factors – the late fruiting period of alien plants and the decreasing availability of native fruits during the vegetation period. Such a set of factors may promote the dispersal of alien plant seeds by carnivorous mammals, which, unlike migrating birds, are constantly present in autumn. The limited availability of native fruits after their fruiting period, creating a phenological gap, makes alien plants the main source of fleshy-fruits at the end of vegetation period in forest ecosystems; this is expressed in high proportion of alien plants in seed FO%, and in significant interactions in the seed load in carnivore scats.
First record of subgenus Synaldis Foerster (Hymenoptera, Braconidae, Alysiinae, Dinotrema Foerster) from Chile, with description of ten new species
Authors: Dias de Oliveira Franciélle , Penteado-Dias Angélica Maria
Published: July 2024

Synaldis is a taxon within the Aspilota group with a contentious taxonomic history, currently classified as a subgenus of the genus Dinotrema. Species of Synaldis were only documented in the Neotropical region in 2017, and until then, the Neotropical fauna of this subgenus was represented by five species from Brazil. In this study, Synaldis is reported for the first time in Chile, with the description and illustration of ten new species, namely: Dinotrema (Synaldis) acarinareolatumsp. nov., D. (S.) brunneumsp. nov., D. (S.) chilensesp. nov., D. (S.) daltonisp. nov., D. (S.) flavumsp. nov., D. (S.) latusdentertiumsp. nov., D. (S.) perisfelipoisp. nov., D. (S.) pilosicaudatumsp. nov., D. (S.) puyehuesp. nov., and D. (S.) veraesp. nov. The studied specimens were collected during expeditions to southern Chile, in the Valdivian temperate rainforest at Parque Nacional de Puyehue. This study also includes a dichotomous identification key for Neotropical species of Synaldis, as well as a discussion of the primary morphological characters used to distinguish species within the Neotropical and Nearctic regions.
Effects of sediment disturbance by the heart urchin Echinocardium cordatum on the sediment–seawater solute exchange: An exclusion experiment
Authors: McLeod Roen , Simone Michelle N. , Vopel Kay
Published: July 2024

Spatangoid heart urchins are dominant bioturbators in marine soft-sediment ecosystems worldwide. Their repeated sediment reworking prevents biogeochemical sediment stratification and colonization by other species, with implications for sedimentary reaction processes that affect the local sediment–seawater solute exchange. Here, we used a simple exclusion experiment to investigate how a subtidal Echinocardium cordatum population (18.2 ± 6.7 individuals m−2), foraging at an individual speed of ~45 cm per day affects the sediment–seawater solute exchange. To do so, we removed all heart urchins from eight one-meter-diameter areas of the 10-m deep seafloor of Man O'War Bay, Hauraki Gulf, New Zealand, and prevented recolonization and thus sediment reworking for 56 days. Subsequently, we measured the sediment–seawater exchange of O2, NO3–, NO2–, NH4+, and N2 both within and outside the exclusion areas, under light or dark conditions, and found no difference. The absence of a legacy effect of foraging E. cordatum after their removal suggests that, at least in this habitat, their influence on the sediment–seawater solute exchange may be limited to sediment being displaced in the immediate surrounding of the urchin. This unexpected result underlines the importance of evaluating the influence of bioturbators on the sediment–seawater solute exchange in the context of local environmental conditions, animal behavior, and population characteristics.

We provided a generalization of the existence and uniqueness of fixed points in partially ordered metric spaces for a monotone map. We applied the major results in the investigation of coupled fixed points for ordered pairs of two maps that met various monotone features, which included a mixed monotone property or a total monotone property. To ascertain necessary requirements for the existence and uniqueness of solutions to systems of matrix equations, the results regarding coupled fixed points for ordered pairs of maps were utilized. These results are illustrated with numerical examples. Some of the known results are a consequence of the results we obtained.

Rural Tourism Management Cloud Service Platform Based on Interactive Mobile Embedded Systems
Authors: Luo Shanshan
Published: July 2024

Aiming to address the issues of low data execution efficiency and slow storage speed on traditional tourism cloud service platforms, a rural tourism management cloud service platform based on an embedded system is proposed. The embedded device components, such as the ARM processor, NOR Flash memory, and RTL network chip, are utilized to optimize the hardware structure of the cloud service platform. This optimization aims to enhance data processing and storage efficiency, as well as improve the reliability and durability of system operation. The unstructured feature grasping algorithm is employed to gather rural tourism resource data for target demand characterization. Associated algorithms are then utilized to develop data analysis, service recommendation, and tourism management modules, creating a comprehensive tourism cloud service platform. Additionally, the shortest path algorithm is used to enhance database storage speed, improve business docking efficiency, establish a big data monitoring center, comprehensively monitor changes in the scenic area and related industries, and enhance platform service efficiency. It has been proven through experiments that the latency of the tourism management cloud service platform, based on the embedded system, is reduced by almost 46.7% compared to the traditional approach, and the throughput is increased to 0.69 b/s. The practical application effect is positive, as it contributes to the development of tourism resources and the economic growth of rural areas. It also brings about economic and social benefits.
Exploring the Effects of COVID-19 on the Racial Disparities and Inequities of Maternal Health: A Survey-Based Study
Authors: Pagadala Trishya , Smyer Mabry
Published: July 2024

Utilizing a cross-sectional survey design, undergraduate researchers at the University of Pittsburgh launched an investigation into the impact of the COVID-19 pandemic on maternal health, with a particular focus on inequity in care. This study utilized a survey, titled COVID-19 Maternal Health Experiences (CMHE) Survey, to explore stress levels and personal accounts of perceived differences in maternal health care in the United States following March 2020. It was hypothesized that the pandemic, having upended and permanently reshaped health systems in the U.S., would reveal broader truths about privilege and inequity in the context of women’s health and motherhood. The responses gathered from 119 participants, predominantly from Pennsylvania, revealed heightened stress concerning health and childcare since the national outbreak of the pandemic. The homogeneity of participant demographics limits this survey results’ generalizability and the ability to perform a racial analysis, emphasizing the need for diverse samples in future research. Despite limitations, the findings of this study highlight the importance of continued research on issues in maternal health care, as well as the importance of providing mothers of all ethnic backgrounds with equitable care and an outlet to express concerns related to their physical, mental, and emotional health.

After decades of descriptive studies, the biology of cancer is undergoing a real revolution: with genetic approaches, researchers have identified many of the cell deregulations likely to drive tumours. A treatment combining arsenic and retinoic acid targets the protein responsible for promyelocytic leukaemia. This treatment, which has cured virtually all patients, gives hope that the in-depth understanding of carcinogenesis mechanisms may lead to new therapeutic approaches that could be transposed to other cancers.
Enquête sur les jardins et savoirs jardiniers de La Réunion : premiers résultats d’une recherche sur la biodiversité « cultivée »
Authors: Clément Sébastien
Published: July 2024

Cet article, issu d’une recherche doctorale, propose d’apporter des repères sur la dynamique de la biodiversité dans les jardins privés de La Réunion. Il s’agit d’interroger ici les conditions de production d’une biodiversité « cultivée », inséparable des modes d’habiter locaux, de savoirs et savoir-faire inscrits dans des héritages culturels, ainsi que des relations sociales tissées autour des jardins. L’approche propose l’étude d’une mesure du niveau de biodiversité à travers un protocole scientifique précis combinée à l’analyse des pratiques et des savoirs investis dans la création et l’entretien des jardins. Cette démarche permet d’évaluer l’impact de la transmission des savoirs des jardiniers et leurs interactions aux espèces vivantes. Elle s’appuie sur des entretiens avec les jardiniers et sur une expérimentation consistant en la création collective d’un jardin sur une parcelle en friche dans l’ouest de l’île à 350 mètres d’altitude et une enquête quantitative sur l’évolution des espèces de la flore et de la faune. Les premiers résultats de cette recherche révèlent un enrichissement du nombre d’espèces et la genèse d’une biodiversité « cultivée ».
Une approche paysagère des effets de 30 années de développement de jardins partagés
Authors: Robert Morgane
Published: July 2024

Cet article propose de développer une approche paysagère des dynamiques socio-écologiques de jardins partagés appliquée à une étude de cas : celle du quartier du Grand Parc à Bordeaux. L’implication historique de la Scop SaluTerre dans la conception de ces jardins constitue un support d’analyse des mécanismes de régulation de phénomènes d’exclusion sociale, ainsi que de l’action publique et de ses effets sur le paysage. Nous développons l’hypothèse selon laquelle l’institutionnalisation des jardins partagés – à la différence de leur émergence directement au sein de communautés habitantes – impose par divers mécanismes des formes et pratiques paysagères potentiellement excluantes de certains usages et catégories sociales.
