Published: October 2024

Continuous use of blue swimming crab (Portunus pelagicus) without any control can cause population decline which leads to damage to the stability of the marine ecosystem, especially in East Coast Pangandaran, therefore cultivation is needed. In aquaculture, it is necessary to provide the right feed by knowing its natural diet. This study aimed to determine the natural diet of blue swimming crabs. The method used was descriptive analysis. The parameters observed were carapace width, gastric weight, the composition of natural diet. The relationship between the carapace width and gastric weight was analyzed by simple regression while the main type of natural diet was known by calculating the percentage of food composition. The relationship between carapace width and gastric weight was positive. Based on the composition found in crab gastric, there were 5 types of natural foods consisting of crustaceans (28.35%), meat (25.37%), mollusk (18.65%), fish (15.67%), and undefined material (UM) (4.47%). It is revealed that crabs are carnivores and scavengers, pose significant relationship between their size and gut content weight. It was also found that the composition of female crab feed was generally higher than that of males.

Provenance of Paleogene Strata at Slim Buttes, South Dakota: Implications for post-Laramide Evolution of Western Laurentia
Authors: Moll Joseph , Maher Harmon , Malone Joshua , Malone David , Craddock John
Published: October 2024

Slim Buttes is a 30 km long by 10 km wide set of buttes containing Paleogene strata in northwest South Dakota. At Reva Gap in northern Slim Buttes, Eocene-Oligocene terrestrial strata of Chadron and Brule Formations of the White River Group unconformably overlie the Paleocene Fort Union Formation. An angular unconformity separates the White River Group from overlying Oligocene and Miocene strata of the Arikaree Group. Using detrital zircon U-Pb ages, we determine the provenance of these rocks as part of a broader synthesis of post-Laramide sedimentation in the Rocky Mountains and western Great Plains.

The Chadron Formation age spectrum is dominated by Cretaceous and Proterozoic grains that are interpreted to be locally recycled from the underlying Cretaceous and Paleocene strata. The Brule Formation has a maximum depositional age of ~34 Ma; Paleogene zircons dominate the age spectrum, and a wide variety of older zircons are also present. The Oligocene zircons are interpreted to have been sourced from volcanic systems in the Great Basin to the southwest, while the subsequent proportions of the zircons were derived from a variety of source areas in the Nevadaplano and Rocky Mountain areas to the southwest. Sparse amounts of Archean zircons are thought to represent the burial of Laramide uplifts throughout Wyoming at the time of Brule deposition, making for a regional paleotopography with little relief across the western interior of the United States. The Miocene-age Arikaree Group sand has a maximum depositional age of ~26 Ma and a multimodal detrital zircon age spectrum. The Arikaree Group provenance likely represents continued sourcing in the Great Basin volcanic systems and Nevadaplano, the beginnings of the re-exhumation of Laramide basement uplifts, and subsequent sediment evacuation out of the western interior and into the Gulf of Mexico to the southeast. Our findings indicate that the transport process and detrital zircon provenance signatures of these strata are decoupled, and each have their own independent evolution. The volcanic signature is primarily transported via aeolian processes (i.e. volcanic ash), and the recycled detrital zircon signature is primarily transported via fluvial processes.

Physiochemical and Mechanical Aspects of CO2 Storage in Deep Saline Aquifers: An Experimental Study
Authors: Ahmed Musa E. M. , Paker Deniz M. , Dindoruk Birol , Drylie Stephen
Published: October 2024

The storage of carbon dioxide (CO2) in subsurface reservoirs is an important option for mitigating anthropogenic greenhouse gas emissions and addressing the global challenge of climate change. However, implementing carbon capture and storage (CCS) technologies involves many complex and coupled processes requiring thorough investigation. These complexities arise from the complex interactions in the subsurface between geological, hydrological, geochemical, and geomechanical factors. Understanding and managing these multifaceted processes are essential for successful and safe deployment of CCS as a vital component of sustainable energy and environment strategies. This experimental study investigates the multi-threaded impact of CO2 storage within a sandstone reservoir.

We employ a comprehensive approach, integrating batch reactor, X-ray diffraction (XRD), inductively coupled plasma (ICP) analysis, acoustic measurements, and routine core analysis (RCA) to examine the physiochemical and mechanical response of the selected rock-fluid system. We measured the changes in Berea sandstone before and after 30 days of CO2 storage at selected reservoir conditions (1500 psi and 150°F). Cores and effluent fluids collected at the end of the storage period were analyzed to measure the changes in the critical geochemical and geomechanical parameters (i.e., rock porosity, permeability, mineralogy, mechanical properties) between post-storage and pre-storage. The novelty of this work lies in its comprehensive and multi-dimensional approach to studying CO2 storage in sandstone reservoirs (i.e., saline aquifers), providing valuable insights for the advancement of sustainable carbon capture and storage solutions.

The results reveal significant alterations in mineralogy, fluid chemistry, and geomechanical stability. Notably, XRD analysis indicated the formation of new mineral phases, such as halite, and the dissolution of carbonate minerals. ICP analysis showed substantial increases in bicarbonate and sulfate ion concentrations, indicating intense mineral dissolution and ion exchange processes. RCA data demonstrated a decrease in porosity by 0.5% and permeability by 24.0%, attributed to mineral precipitation within pore spaces. Acoustic measurements highlighted changes in geomechanical stability, with alterations in acoustic velocities reflecting changes in rock stiffness and density

This research advances our quantitative understanding of the complex interactions within sandstone reservoirs during CO2 storage at the selected timescale that can capture the first order changes in the rock-fluid system. It provides critical information on kinetics, petrophysical properties and geomechanics, contributing essential knowledge for safe and efficient carbon capture and storage (CCS) technology implementation.

Published: October 2024

Background: Acute heart failure is the gradual or rapid change of heart failure signs and symptoms, which poses a unique diagnostic and management challenge, requiring urgent therapy. It is responsible for nearly one million hospitalizations each year globally with rising rates. Despite therapeutic advances, it is associated with poor prognosis. Therefore, his study aimed to assess in-hospital mortality and its associated factors among adult acute heart failure patients in a tertiary hospital, Harar, Eastern Ethiopia.
Methods: A hospital based retrospective cross-sectional study was employed among 454 adult acute heart failure patients treated in the medical ward of Haramaya University Hiwot Fana Comprehensive Specialized Hospital from June 01, 2016 to May 31, 2021. Data was collected using structured data abstraction format from July 15 to August 14, 2021. Collected data was entered to Epi-Data version 3.1, exported to, and analyzed using statistical package for social science (SPSS) version 21.0. Bivariate and multivariate logistic regression was used to identify factors associated with in-hospital mortality.
Results: A total of 454 acute heart failure patient’s medical records were reviewed. More than half, 282(62.1%) of patients were females. The median age of patients was 45 years (±28 IQR). In-hospital mortality was 18.9% and it was more prevalent in the first week of admission, 61(70.9%). Sex (female) (adjusted odds ratio (AOR) = 2.83, P = 0.001)), having smoking history (AOR = 2.51, P = 0.031), generalized body swelling (AOR = 2.67, P = 0.001), hypotension (AOR = 4.56, P = 0.001), and tachycardia (AOR = 4.57, P = 0.000) were factors associated with in-hospital mortality.
Conclusions: In-hospital mortality is found to be very high among acute heart failure adult patients. Therefore, dedicated programs need to be developed to reduce mortality from acute heart failure and further prospective study should be conducted to investigate the problem in-depth.

The presence and extent of metastatic disease in axillary lymph nodes (ALNs) in the setting of breast cancer (BC) are important factors for staging and therapy planning. The purpose of this study was to perform a multiparametric sonographic evaluation of ALNs to better differentiate between benign and metastatic nodes. Ninety-nine patients (mean age 54.1 y) with 103 BCs were included in this study, and 103 ALNs were examined sonographically. B-mode parameters, such as size in two dimensions, shape, cortical thickness and capsule outline, were obtained, followed by vascularity assessment via colour Doppler and microflow imaging and stiffness evaluation via shear wave elastography. Postoperative histopathological evaluation was the reference standard. In the statistical analysis, logistic regression and ROC analyses were conducted to search for feature patterns of both types of ALNs to evaluate the prediction qualities of the analysed variables and their combinations. For a cortex larger than 3 mm, without a circumscribed margin of the LN capsule and SWE (E max > 26 kPa), the AUC was 0.823. Multiparametric assessment, which combined conventional US, quantitative SWE and vascularity analysis, was superior to the single-parameter approach in the evaluation of ALNs.

Published: October 2024

This research was conducted to determine the effect of bacterial strains isolated from different sources on the development of melon plants. Plant growth promotion mechanisms such as calcium, potassium and phosphorus solubilization, nitrogen fixation, phytohormone, siderophore and ACC-deaminase production and their growth at different pH and salt concentrations were determined. In order to determine the effect of bacterial strains on plant growth, field trials were established according to the randomized blocks experimental design with three replicates and carried out with two years of repetition. In the experiment established for this purpose, 11 different applications [IT 22 (Bacillus safensis), IT 22 + Fertilizer, IT 63 (Acinetobacter calcoaceticus), IT 63 + Fertilizer, IT 93 (Acinetobacter calcoaceticus), IT 93 + Fertilizer, IT 115 (Serratia rubidaea), IT 115 + Fertilizer and control (fertilizer only)] were included. In terms of all parameters examined, the best result was obtained from the Mix + Fertilizer application, while only the highest value of WSDM (9.9%) was measured in the IT 93 + Fertilizer application. The results of the study show that fertilizer-free IT 93 and Mix applications provide higher melon yield than fertilizer, suggesting that bacterial single or mixed applications can be used as a very effective method to reduce the use of chemical fertilizers. In addition, higher fruit yield per decare was obtained in the blocks where bacteria and fertilizer were applied together, except for IT 115 + Fertilizer application, compared to the control group. This result was an indication that a significant reduction in chemical use will be achieved with the inclusion of the determined bacterial strains in fertilization programs.

Bioremediation using plants and microorganisms effectively mitigates heavy metal soil contamination and improves soil conditions. Phytoremediation with leguminous plants and rhizobacteria enhances metal bioavailability and promotes plant growth. This study evaluates microbial community structure in soils with varying concentrations of tailings from the Fundão Dam disaster in Mariana, MG, Brazil. Microbial diversity was measured by fluorescent in situ hybridization in treatments with different tailings concentrations and in the presence of Leucaena leucocephala. Higher tailings proportions reduced bacterial densities, with pure ore tailings (T100%) showing the lowest bacteria percentage. However, after 14 months of leucaena cultivation, this treatment had the highest number of prokaryotes. The presence of leucaena plants modified the densities of Bacteroidetes and the Pseudomonas genus. Experimentation time influenced the densities of Actinobacteria, Acidobacteria, and Firmicutes. The interaction between legume presence and sampling time altered the density of Proteobacteria and Gallionella ferruginea. The results show that iron ore tailings impact the microbial community in the plant rhizosphere, offering insights for bioremediation strategies to restore soil quality in mining-affected areas.

Aim: This study analyzed the associations between various clinical and imaging parameters with overall survival (OS) and recurrence-free survival (RFS) in vulvar cancer.
Materials and Methods: A total of 45 patients diagnosed with vulva tumors were retrospectively analyzed. Data were extracted from medical records, including age, tumor size, ADC, SUVmax, and metastases identified through MRI and PET. Survival outcomes were estimated using Kaplan-Meier methods, while associations between variables and survival were assessed using Cox regression. Optimal cut-points for continuous variables were determined using maximally selected rank statistics.
Results: The median OS was 9.97 years, with age, tumor size, and SUVmax measurements significantly influencing OS. Optimal cut-points at 4-year survival were established for age 65.9 years, the largest axial dimension of 5.50 cm, craniocaudal dimension of 4.7 cm, SUVmax of 22.0, and ADC value of 1.026 x10-3 mm2/s. Patients with measurements above these cut points typically had worse survival outcomes.
Conclusion: Age, Size, and SUVmax predict survival in patients with vulvar cancer.

There is a correlation between glucose variability (GV) after cardiopulmonary bypass (CPB) and major adverse events. Identifying early risk factors and developing a prediction model for preventing GV is crucial. No machine learning models have been developed for GV in non-diabetic patients during CPB cardiac operations. This study established six models: logistic regression (LR), random forest (RF), decision tree (DT), support vector machine (SVM), eXtreme gradient boosting (XGBoost), and categorical boosting (CatBoost). Each model was internally validated, and the SHAP method identified important variables. Among 360 non-diabetic patients, 213 (59.17%) developed GV in the ICU. The models showed AUC values from 0.7400 to 0.818 in the training set and from 0.6658 to 0.763 in the testing set. XGBoost performed best, with an AUC of 0.736, accuracy of 0.7798, sensitivity of 0.875, positive prediction value of 0.7778, F1-score of 0.8235, and Brier score of 0.2041. Postoperative insulin, BMI, intraoperative mean glucose, and CPB duration were crucial features. By combining XGBoost with SHAP, the developed models can be used to facilitate individualized risk evaluation, allowing timely intervention or targeted care.

Several mutations of the sorghum [Sorghum bicolor (L.) Moench] GRANULE-BOUND STARCH SYNTHASE (GBSS) gene [Sobic.010G022600] result in a low amylose:amylopectin starch ratio in the endosperm and confer a glutinous, “waxy” texture; hence, the wild-type gene is commonly referred to as Waxy (Wx). Recessive waxy (wx) alleles improve starch digestibility in ethanol production, human foods and beverages, and animal feed. However, breeding waxy sorghum can be time-consuming due to the need for grain to reach physiological maturity before the trait can be phenotyped and ongoing reliance on PCR markers for genotyping, which are not amenable to next-generation sequencing (NGS). Modern genomics-assisted breeding requires conducing high-throughput genotyping and selection in large, segregating populations prior to flowering. This study provides the first published NGS markers for the two mostly commonly used waxy (wx) alleles of sorghum and is the first to fully characterize the large insertion that is causal of the wxa allele. An enhanced genome assembly was constructed from the B.Tx623 reference genome (v3.1.1) to include the 5.6 kb large retrotransposon derivative (LARD) in the wxa allele. This improved read mapping at Sobic.010G022600 in wxa individuals, identified 78 new uniquely mapped reads, and made it possible to distinguish different Waxy genotypes using short-read sequencing data. Functional PACE-PCR markers, suitable for genomic selection, were developed for Wx, wxa, and wxb alleles and validated in three public and private breeding programs. These new molecular breeding resources will improve the efficiency of developing commercial waxy sorghum hybrids.

Objective: This study aimed to analysis of risk factors affecting prognosis of fulminant myocarditis in children.
Methods: We retrospectively reviewed the medical records of all patients (n=40) diagnosed with fulminant myocarditis and admitted to the Cardiac Intensive Care Unit (CICU) and Pediatric Intensive Care Unit (PICU) at the Women and Children's Medical Center of Guangzhou Medical University between January 2014 and December 2023. Patients were divided into two groups based on their in-hospital prognosis: a survival group (n=32) and an non-survival group (n=8). Baseline demographics, laboratory findings, electrocardiograms, echocardiograms, and treatment regimens were compared between the two groups in a multifactorial analysis.using appropriate statistical tests.
Results: The median age of patients in the survival group was 7.8 years old (M[5,11.5]), and the median age in the non-survival group was 9.0years old (M[6,11.5]). Compared to the survival group, patients in the non-survival group had significantly higher levels of extracorporeal cardiopulmonary resuscitation(ECPR) use, ventricular tachycardia/ventricular fibrillation (VT/VF), peak creatine kinase isoenzyme (CK-MB), peak N-terminal B-type natriuretic peptide precursor (NT-proBNP), serum creatinine (Scr) on admission and peak, peak aspartate aminotransferase (AST), peak alanine aminotransferase (ALT), peak cardiac troponin I (cTnI), lactate on admission and peak, and extracorporeal membrane oxygenation(ECMO) use (all p<0.05). Binary logistic regression analysis identified peak lactate level as an independent risk factor for mortality in patients with fulminant myocarditis (OR = 0.661, 95% CI 0.488-0.897, p=0.008).
Conclusions: This study demonstrates that peak lactate level is an independent risk factor for mortality in patients with fulminant myocarditis.
Ubiquitination of gasdermin D N-terminal domain directs its membrane translocation and pore formation during pyroptosis
Authors: Chu Xiufeng , Zheng Pengyuan , Ihtisham Bukhari
Published: October 2024

Gasdermin D (GSDMD) is a critical mediator of pyroptosis, which consists of a N-terminal pore-forming domain and a C-terminal autoinhibitory domain. The free N-terminal domain (GD-NT), which is released through caspase-1/11 cleavage, exhibits distinct features from the full-length GSDMD (GD-FL), including oligomerization, membrane translocation and pore-formation. However, the underlying mechanisms are not well clarified. Here, we found that GD-NT, but GD-FL, was massively ubiquitinated in cells. The K63-linked polyubiquitination of GD-NT at Lys236/237 (human/mouse), catalyzed by TRAF1, directly its membrane translocation and pore-formation during pyroptosis. Inhibition of GD-NT ubiquitination via site mutation or the UBA1 inhibitor PYR-41 suppressed cell death in several pyroptosis cell models. Additionally, the application of PYR-41 in septic mice efficiently suppressed the release of IL-18 and TNF-⍺. Thus, GD-NT ubiquitination is a key regulatory mechanism controlling its membrane localization and activation, which may provide a novel target for modulating immune activity in pyroptosis-related diseases.

Deep eutectic solvents (DES) are gaining recognition for their utility in the cost-effective and high-solubility pretreatment of lignocellulosic biomass. The unique combination of Brønsted acid and Lewis acid in DES gives it the ability to break hydrogen and ether bonds in lignin-carbohydrate complexes (LCCs) and can be applied to the extraction catalysis of lignin. This study investigates the efficacy of a dual-acidic DES in extracting lignin from Camellia oleifera shells, with the assistance of microwave irradiation. Our findings reveal that a DES composed of ZnCl2 and lactic acid in a ratio of 1:8(n/n) exhibits optimal performance. Utilizing this DES, we achieve the rapid extraction of lignin with a purity of 91.2%, yield of up to 97.1%, and a low polydispersity index of 1.49, within a remarkably short timeframe of 10 min, under microwave power of 70 W. Characterization by Infrared spectroscopy and NMR spectroscopy indicates that the extracted lignin is of GS type, predominantly preserving its C-C bonds while exhibiting a reduction in ether linkages. Furthermore, the study elucidates that the formation of extensive hydrogen bonding interactions between the dual-acidic DES and lignin is pivotal for the efficient extraction process, while also preserving the structural integrity of cellulose. Additionally, hemicellulose is mainly converted into furfural. The lignin derived from Camellia oleifera shells demonstrates the considerable potential for the production of platform chemicals, liquid fuels, and biomass-derived materials.

Published: October 2024

The current use of identifiers to describe immigrant patients in Electronic Health Records (EHRs) is poorly described and lacks standardization, but nevertheless has broad implications related to clinical care and research of this population. We conducted interviews with key informants to discern strong identifiers for use to identify patients who have immigrated to the United States (U.S.). Language, country of origin, time in the U.S., and race/ethnicity were identified as effective, ethical, and acceptable for use. Limitations of each of these identifiers were noted, highlighting the need to use multiple identifiers in combination when describing patients in EHRs. The processes used to collect these identifiers in clinical settings and the ethical implications of using these identifiers must also be carefully considered. Our results highlight the need for standards related to documentation of immigrant patients in EHRs. Further research is also needed to validate the identifiers we have outlined, discern additional identifiers that are useful and acceptable in specific clinical and research contexts, and explore how strong identifiers can be operationalized in EHRs for clinical, research, and community engagement purposes.
