Wild orchids hold significant ecological value, yet current research mainly focuses on germplasm resources, lacking systematic studies on the native habitats and root endophytic fungi of species like Cymbidium goeringii and Cymbidium faberi. This study used fungal sequencing to explore the fungal community in the native habitats of these orchids in the Qinling Mountains. We compared rhizosphere and non-rhizosphere soil fungi and assessed the ecological functions of dominant fungal groups. The impact of soil chemical indicators on fungal communities was also analyzed. Endophytic fungi were isolated from orchid roots to evaluate their growth-promoting potential. Results showed that Ascomycota and Basidiomycota were dominant in the rhizosphere of both species. Symbiotic nutrient and pathology-saprophytic-symbiotic mixed fungal types were predominant, accounting for 56.76% and 79.17% of the fungal community, respectively. Soil factors like total nitrogen and ammonium nitrogen correlated strongly with these communities. A total of 17 fungal strains were isolated, with strains HL01, HL02, HL06, and HL17 exhibiting indole-3-acetic acid (IAA) production, nitrogen fixation, and phosphorus solubilization. Strain HL08 showed IAA production, nitrogen fixation, and potassium solubilization. These strains contribute to enriching growth-promoting fungal resources for both species. This research provides a theoretical and scientific basis for the conservation, artificial cultivation, and breeding of Cymbidium goeringii and Cymbidium faberi.

Genomic studies have revealed introgressive hybridization as a common phenomenon across the tree of life, particularly among young radiations. As incipient speciation tends to be induced by vicariance events, it is assumed that introgressive hybridization is more frequent in young radiations in which allopatrically distributed species have a high probability of coming into secondary contact. In this study we utilize whole genomic data to investigate spatio-temporal introgression patterns in a songbird radiation that has colonized a highly dynamic island region in the Indo-Pacific. Some taxa within this radiation have colonized remote oceanic islands whereas others occur on landmasses and islands in the Sahul region that were periodically connected during Pleistocene periods of lower sea levels. Our results show that introgressive hybridization has been pervasive within this young radiation, despite prominent plumage differences between taxa. Geographical proximity has been an important factor for hybridization and we further find that species occupying islands in the environmentally unstable Sahul region exhibit particularly high signatures of introgressive hybridization. Yet, one species appears to have been shielded against hybridization, perhaps due to specific ecological specializations. Finally, we identify a hybrid species on an island where two oceanic radiations meet. Our results also caution against relying solely on analyses that only detect asymmetric introgression when examining systems with complex introgression histories. Collectively, our results support a growing body of literature that suggests that reticulate speciation is much more common than previously thought. This has implications for our understanding of species formation and their persistence through time.

Lepidagathis kurnoolensis sp. nov. is a decumbent, woody undershrub found in scrub forests dominated by quartzite stones near Orvakal Mandal in the Kurnool District. This new species resembles Lepidagathis diffusa C.B.Clarke with respect to habit, leaf shape, inflorescence, number of sterile bracts, corolla and fruits but can be distinguished by differences in spike size, morphology of sterile bracts and bracteoles, size and shape of bracts and calyx, and nature of seed. It also resembles Lepidagathis spinosa Wight ex Nees in spike appearance, sterile bract shape, corolla, and fruit shape but differs in its wood nature, leaf shape and size, bracts and bracteoles surface nature, seed morphology and anatomy of stem. A detailed description, illustrations, and field images are provided for easy identification along with a comparative table highlighting the morphological characters of allied species. The IUCN conservation assessment for this species is discussed.

Technological developments are a great advantage for biodiversity monitoring, if they are cross-validated with established protocols before their routine application. In the context of fish communities’ characterization, portable sequencers such as Oxford Nanopore Technology (ONT)’s MinION devices have the power to revolutionise field surveys through eDNA metabarcoding. However, Nanopore’s raw reads high error rates can disincentivise its use when compared to Illumina sequencers. Here, three sequencing protocols (two for Nanopore and one for Illumina) targeting short and long regions of two mitochondrial genes (12S and COI) were compared using fish mock communities and environmental DNA samples from mesocosm and field environments. Raw read quality, species richness detected, and taxonomic resolution of the platforms and genes were assessed. The latest Nanopore chemistry was comparable to Illumina for number of species retrieved, however discrepancies in species detected were observed between platforms and genes. Long amplicons provided higher taxonomic resolution compared to the short fragments. The 12S markers outperformed COI by detecting a higher number of species, while a multi-marker approach increased overall species richness in most cases. Sequencing technologies and primer selection can have significant impacts on fish eDNA metabarcoding results. Given its high specificity and taxonomic resolution, the long 12S region is presented as a promising marker for long-read metabarcoding. The latest Nanopore sequencing technology successfully profiled fish communities from mock and eDNA samples and due to its portability, quick turn-around time and reduced costs provides an innovative tool to conduct field-base studies.

Music separation focuses on isolating individual components, such as vocals and instruments, from mixed audio tracks. This process has gained significant attention due to its diverse applications, including music remixing, karaoke systems, audio restoration, music information retrieval (MIR), music education and practice, forensic audio analysis, music transcription, gaming and virtual reality (VR), performance analysis for musicians, and music sampling and licensing. This study investigates feature extraction from audio sources using DenseNet, employing diverse datasets such as DSD100, MUSDB, and MUSDB18-HQ, which offer a wide variety of musical compositions for benchmarking. To evaluate the accuracy and reliability of the techniques, metrics such as Precision, Recall, and F1-score are used to assess the efficiency of feature extraction. Among these datasets, MUSDB18-HQ demonstrates superior performance, particularly for extracting features related to vocals and drums. By providing insights into the potential and challenges of music separation, this study contributes to the ongoing development of music technology and its applications.

Summary Background: The distribution pattern of central tarsal bone (CTB) changes has not been described, except for slab- and dorsomedial-plantarolateral fractures. Objectives: The goal was to describe CTB changes in CT, their distribution and associations, hypothesizing that changes occur mainly dorsomedially and that most fissure/fractures are linked to demineralization. Study design: Retrospective Methods: Standing and recumbent tarsal CTs from 94 clinical cases were retrospectively evaluated. Besides general case information, degree of sclerosis (none-severe), lesions (demineralization, cystoid, fissure/fracture) and their location were recorded dividing CTBs in 8 regions. Results: 85/94 tarsi showed at least one region of moderate to severe sclerosis, with 90% affecting the dorsomedial region. The prevalence of lesions was significantly associated with higher degrees of sclerosis (p=0.037) at this site. Of 32 demineralizing lesions, 21 were in the proximal subchondral bone dorsomedially. 24 CTBs showed fissures/fractures and 19/24 were in a dorsomedial-plantarolateral direction, mostly associated with demineralization (17/19). Of 5 fissures/fractures with different configurations, none had associated demineralization. There were 27 cyst-like lesions, 21/27 in the distal subchondral bone and almost half (13/27) were located medially. Main limitations: Retrospective nature; heterogeneous, warmblood oriented, population; no clinical correlation of findings nor histologic confirmation of described changes . Conclusions: Given the links between sclerosis, demineralization and fissures/fractures, the dorsomedial proximal subchondral bone plate of the CTB must be scrutinized both in CT and radiography.

Multiple management strategies have been put in place in Madagascar to slow down biodiversity loss, but evidence for their effectiveness remains scarce. Using a long-term monitoring dataset and a custom-built capture-mark-recapture model, we evaluated the effect of a protected area and translocations on the survival of mouse lemurs (Microcebus murinus) in the littoral forests of southeastern Madagascar. We found that female mouse lemurs had overall higher apparent survival than males, that annual survival probabilities were higher for both sexes in protected forest fragments compared to degraded ones, and that survival of translocated individuals was on average 66% lower than residents. We also evidenced a positive effect of monthly temperature on female survival in protected fragments but found no temporal trend in survival. This study confirms the importance of protected areas as a conservation tool and calls for careful planning of translocation efforts for conservation of short-lived primate species.

Rhabdomyosarcoma (RMS) is a malignant tumor that arises from primitive mesenchymal cells. The most common site is the head and neck, accounting for 40%, followed by the urinary tract at 30%. Clinical suspicion, localization, age, imaging, immunohistochemistry, and molecular studies facilitate an accurate diagnosis and prompt treatment. The current clinical case demonstrates how the correlation of these clinical variables can hinder the progression of this neoplasm in a pediatric patient.

Objective: Pediatric patients with non-rhabdomyosarcoma soft tissue sarcoma (NRSTS) undergo aggressive multimodality treatment. This single institutional analysis of outcomes in this group explored factors associated with local control and survival. Methods: Patients ≤18 years old diagnosed with NRSTS between 10/1990-11/2021 who received radiotherapy (RT) were retrospectively identified. Overall Survival (OS) and disease-free survival (DFS) analyses were performed using Kaplan Meier methods. Cumulative incidence of local and distant failure were estimated. Univariate analysis was performed. Results: Fifty-one pediatric patients with NRSTS were included. Extremity tumors were most common (33/51, 65%), with 80% T1 or T2 (AJCC 8 th) and 90% non-metastatic. Surgery in 49/51 (96%) resulted in 32 (65%) R0 resections. All received RT (median EQD2 50 Gy, range 42.4-76.9), with brachytherapy or intraoperative (IORT) boosts in 21 cases (41%) (mean EQD2 24.5 Gy). Thirty-four (66.7%) received chemotherapy. With 5.7 years median follow up, 5-year OS and DFS were 70.7% and 67.9%, respectively. Positive margins were significantly associated with worse OS on univariate analysis. Two-year local failure incidence for EBRT was 18.1% and 5.3% for EBRT+boost (HR 3.67, p=0.24). Among 6 observed local failures, 5 occurred after EBRT alone, 3 of which had positive margins. Among the EBRT+boost group, 2 had positive margins, neither with local recurrence. Conclusion: Multimodality treatment of pediatric NRSTS results in 5-year OS and DFS around 70%. R0 resection is essential to optimize outcomes in this population. Although incidence of R1 resections has declined in the modern era, IORT/brachytherapy boost may have a role in selected patients at high-risk for local recurrence.

Background: Severe bleeding events caused by Primary immune thrombocytopenia (ITP) in children can be life-threatening or lead to long-term complications. This study aimed to establish a risk assessment model for hemorrhage and provide valuable insights for clinical diagnosis and treatment planning in these children. Procedure: This retrospective study reviewed 500 children with ITP, who were categorized into low-bleeding risk and high-bleeding risk groups. Collected data included disease characteristics and laboratory test, compared the differences of variables between groups. Cohort were randomly split at a 7:3 ratio for training set for model development and test set for model validation, employed six type of machine learning algorithms for bleeding risk assessment model construction and evaluated models based on the ROC curve. Finally employed alignment diagram to visually represent the risk assessment model derived from the optimal algorithm. Results: Age, fever, cytomegalovirus infection, neutrophil percentage, erythrocyte, platelet, activated partial thromboplastin time, aspartate aminotransferase, creatine kinase, creatine kinase MB isoenzyme, urea, creatinine and cystatin C were significant difference between low-bleeding risk and high-bleeding risk groups ( p<0.05). Bleeding risk assessment model include platelet, erythrocyte, creatine kinase, urea, age and cytomegalovirus infection variables presented the best performance among the six prediction models (AUC: 0.815) based on binary logistic regression algorithm. Conclusions: A bleeding risk assessment model for children with primary immune thrombocytopenia which variables include platelet, erythrocyte, etc, based on binary logistic regression algorithm is established and demonstrated the best performance among the evaluated machine learning algorithms.

Purpose: Neuroblastoma is the most frequent extracranial solid tumors in infants, with a characteristic presentation and a possibility of spontaneous regression even in disseminated disease. Despite an overall good prognosis, relapse can occur in some patients, leading to a poorer outcome in a subgroup of patients. A long-term analysis of these patients assessing survival at 10 years from diagnosis is relevant in estimating the risks of late relapse, progression or long-term toxicity due to very young exposure to treatment. Methods: Estimation of the 10-year event-free and overall survivals in 750 infants under 12 months of age with Neuroblastoma, enrolled in the prospective INES protocols between 1999 and 2004. Follow-up data from INES patients were updated, and survival analyses were performed in order to determine prognostic factors such as: age, stage, genomic profile or MYCN amplification. Results: Overall, 10-year OS was 91.1% ± 1.0%, and 10-year EFS was 82.4% ±1.4%, with significantly better outcomes in infants under 6 months compared to those aged 6 to 12 months, even considering the MYCN-amplified tumors only. MYCN amplification was the strongest prognostic factor and was correlated with substantially lower survival rates among patients with metastatic disease. Discussion: Survival in infancy remains excellent and stable even at long term, as a 10-year follow-up did not change the number of events. However, survival in MYCN-amplified tumors remained poor, this population needs to be treated more aggressively. Patients with metastatic tumors require accurate risk stratification, especially for younger infants under 6 months. For each treatment group, there was no significant difference in long-term outcomes compared to previous publications from INES. No lethal toxicity affecting long-term survival occurred.

The mechanism of painful diabetic neuropathy (PDN) is still unclear. This study investigates whether the mechanism involves astrocytes activation and phosphorylation of extracellular signal-regulated kinase (ERK) and modulation of Downstream regulatory element antagonist modulator (DREAM), and Brain derived neurotrophin factor (BDNF) proteins expression that affects the neuropathic pain responses in PDN rats model. Eighty-four Sprague-Dawley male rats were assigned into 6 groups (n=14 per group) consisting of normal control (C), PDN-diabetic (PDN), PDN+ astrocytes inhibitor (LAA) treated: L100 (low dose) and L200 (high dose) and PDN+ ERK inhibitor (U0126) treated: U5 (low dose) and U10 (high dose). After streptozotocin (STZ) was injected, 2 weeks period was allowed for all diabetes mellitus (DM) rats to develop PDN conditions. Then, an intrathecal injection of LAA and U0126 were given for seven days. The neuropathic pain responses were performed by Von Frey, hot plate and formalin test. The rats were sacrificed, and spinal cord were collected for histology and quantitative PCR (qPCR) analyses. The PDN group showed significant increment in GFAP, ERK, DREAM and BDNF mRNA expression level in the spinal cord with increased neuropathic pain responses compared to control group. LAA and U0126 significantly modulated the GFAP, ERK, DREAM and BDNF mRNA expression and alleviated the neuropathic pain responses in the PDN treated group. It suggested that the mechanism of PDN involves astrocytes activation and phosphorylation of ERK to modulate the expression of DREAM and BDNF mRNA levels in the spinal cord that affects the neuropathic pain responses in PDN rats model.

For any wastewater treatment aeration tank, the paper presents a technique to deal with oxygen uptake rate (OUR) measurements that is primarily related to the biological uptake rate. he proposed dilution vs. the “shake it up” aeration approach to avoid shearing the floc which may increase the OUR artificially, jeopardizing the true measurement in the aeration tank. when the level of dissolved oxygen in the medium falls below a certain point, the specific rate of oxygen uptake is also dependent on the oxygen concentration in the liquid. Since it measures the rate at which oxygen is used, it is a useful tool to evaluate process performance, aeration equipment, and biodegradability of the waste. The OUR is a fundamental physiological characteristics of culture growth and has been used for optimizing the fermentation process, and so it needs to be measured accurately. Oxygen uptake rate (OUR) is the microorganism oxygen consumption per unit time and is one of the few accessible parameters to quantify the metabolism rate of the activated sludge in a wastewater treatment plant. To alleviate the many problems of measurement, the proposed method using dilution with saturated DO may give a more accurate measurement than the current standard method using a sample shaking technique as described in APHA 2017. With a more accurate measurement of the OUR, it may lend credence to justification for the modification of the fundamental equation for oxygen transfer in a respiring system, as applied to an example provided by ASCE/EWRI 18-18

Heat adaptation is a multilayered universal process involving a coordinated response of general and heat-specific cellular systems and processes. Here, we demonstrate that adaptation of the plant pathogenic fungus Botrytis cinerea to mild heat stress requires both autophagy and the mitochondrial Lon1 protease. Deleting bclon1 or blocking autophagy by deleting the bcatg1 autophagy-regulating gene did not affect fungal survival at optimal temperature. Under heat stress, deletion of bclon1 induced earlier and more intense autophagy, mitochondrial malfunction, and accelerated fungal cell death. These phenomena were intensified in a bcatg1/lon1 double mutant, indicating coordinated activity of both pathways in heat adaptation. Blocking autophagy, but not bclon1, also affected mycelia growth, spore germination, as well as nuclei division and spore morphology. Our results support a cytoprotective role for autophagy downstream of mitochondria-driven death signals, possibly as a mechanism that promotes growth arrest and helps remove damaged cellular components.

Odonates are bioindicators as they provide information regarding the ecological conditions of freshwater ecosystems. Freshwater resources are under great anthropogenic pressure due to pollution, sediments, drought, and climate change. To list out odonate species in different types of aquatic environments and to identify indicator species, a total of 12 sampling sites in the Karnali River basin were surveyed using an ocular observation method with the help of a sweeping net for the adults and handpicking to the exuviae. Different ecological indices were calculated for different habitat types and study sites. At the same time, linear relationships between different indices were also evaluated. A total of 88 odonata species belonging to 52 genera and 12 families were recorded. Among them, based on the Odonata Value Index (OVI), 29 species were identified as indicator species, where 16 were specialist species and 13 were habitat indicator species. The odonata species richness was high in the lower elevations and remains scarce in higher elevation levels as they have environmental influence. The biotope diversity of dragonflies is found to be low in all study sites. The dragonfly biodiversity indices, i.e., the Dragonfly Biotic Index (DBI) and Habitat Integrity Index (HII), have a significant influence on each other. The study emphasizes the need for conservation priorities in riparian ecosystems and diverse types of habitats for the odonate community and the probability to use odonates to assess ecosystem health. Key words: Dragonfly, damselfly, bioindicator, ecological indices

Exercise influences visual processing and is accompanied by neural and physiological changes in the body. Yet, the underlying mechanisms by which neural and physiological responses to exercise impact ensuing perception remain poorly understood. Particularly, the effects of exercise-induced cardiac changes on visual perception and electrophysiological activity are unclear. Here, we aimed to investigate the relationship between conscious visual perception, neural activity, and cardiac responses during exercise. Thirty healthy participants performed a perceptual suppression task while engaging in light-intensity stationary cycling, with EEG and ECG activity recorded simultaneously. Our study shows that the probability of perceptual suppression decreased during cycling. Parieto-occipital alpha amplitudes (8–12 Hz) also decreased during cycling, but this reduction did not correlate with the decrease in perceptual suppression. Additionally, cycling also decreased heartbeat-evoked potential (HEP) amplitudes, indicating altered neural processing of cardiac signals during exercise and a potential influence of cardiac physiology on HEPs. However, these exercise-induced changes in HEP amplitudes did not predict perceptual outcomes. Moreover, changes in heart rate in response to cycling did not correlate with changes in perceptual suppression rates , pre-stimulus alpha or HEP amplitudes. These findings indicate that while exercise modulates conscious visual perception, the associated changes in alpha activity, heart rate, and HEPs do not fully explain this effect. Our results highlight the complex relationship between interoceptive processing and mechanisms underlying the perception of external stimuli during exercise.

Abemaciclib, a novel cyclin-dependent kinase 4 and 6 inhibitor, shows promising outcomes and far-reaching influence in the therapeutic scenario of women with hormone receptor-positive, human epidermal growth factor receptor 2-negative advanced breast cancer. Query the FAERS database retrospectively to extract reports related to Abemaciclib from the first quarter of 2004 to the first quarter of 2024. Reporting the odds ratio and Bayesian confidence propagation neural networks as well as the information component of the multi-item γ Poisson contractile apparatus was used to quantify the adverse event signal of the Abemaciclib.10,070 reports of Abemaciclib were identified and significantly associated with an increased risk of blood lymphatic system disorder and hepatobiliary disorders at the SOC level. New and Unexpected AEs include Embolism venous, Lymphangiosis carcinomatosa, Malignant neoplasm progression, Blood creatinine increased and Thrombosis were also be detected. The median time to onset of Abemaciclib-related AEs was 33 days, with the majority occurring within the initial month of Abemaciclib treatment. Gender and age differences existed in in the top 30 signal strength of PTs related to Abemaciclib. Our study found significant new AEs signals of Abemaciclib and reveal that different patient characteristics (such as age, gender, severity) affect treatment outcomes, which might provide support for clinical monitoring and risk identification of Abemaciclib.Our study validates the common AEs and some potential emerging safety concerns related to Abemaciclib in real clinical practice, which could potentially prompt increase the awareness of toxicities for Abemaciclib.

Aim: Ensuring medication safety continues to be a challenging problem in older adults with multiple chronic diseases. This study aims to investigate the association of potentially inappropriate medication use with healthcare utilization and mortality and also explore the influence of pay-for-performance programs in multimorbid older adults in Taiwan. Methods: The study population was comprised of older adults aged 65 years or older with multimorbidity and at least one outpatient drug prescription in 2018. Healthcare utilization (outpatient clinic visit, emergency room visit, hospitalization) and medical cost at six months were analyzed using general linear model (continuous) and multiple logistic regression (categorical). Mortality at one year was determined using Cox-proportional hazard regression model. Separate analyses were performed for disease subgroups with pay-for-performance programs. Results: The prevalence of PIM use was 85.6% in the multimorbid older adult population. PIM use was associated with increased outpatient clinic visit (β=0.0591, SE 0.0008, p<0.0001), emergency department visit (aOR 1.103, 95% CI 1.094-1.112, p<0.0001), hospitalization (aOR 1.131, 95%CI 1.120-1.143, p<0.0001), and total medical cost (β=0.0507, SE 0.0024, p<0.0001). After adjusting for covariates, PIM use had higher risk of mortality at one year (aHR 3.509, 95%CI 3.285-3.748, p<0.0001). The positive association of PIM use with healthcare utilization attenuated with enrollment in pay-for-performance program. Conclusion: PIM use was significantly associated with increased risk of healthcare utilization and mortality in older adults with multimorbidity, which indicated the need for selection of safer drug therapy or alternatives in this vulnerable population.

Mite-plant defense mutualisms are among the most common defense mutualisms in the world - yet studies providing basic information on their prevalence in plant communities remain rare. Here, we systematically surveyed common woody plants in a North American deciduous forest for the presence of plant-mite mutualistic interactions. We scored the 16 most common woody species for the presence and number of mite domatia - small structures on the underside of plant leaves that are known to house mutualistic mites. We found that 80% of common woody species in the forest had mite domatia, the highest reported percentage of mite domatia in any survey conducted thus far. We paired our survey with a quantification of the number of mites found on each leaf and investigated the relationship between mite domatia and mite abundance within and across species. We found that plants with mite domatia had significantly more mites on their leaves than species that lacked mite domatia, and that plants with more domatia had more mites. Together, our study provides much needed systematic survey data on plant-mite mutualism prevalence in an important plant community, and points to northern temperate forests as a promising system to study plant-mite mutualisms in high densities in the future.

This study primarily sought to assess vegetation composition, diversity, and distribution across six significant grazing sites in Khartoum State, Central Sudan. This study also aimed to elucidate the diet of small ruminants and camels through the analysis of plant pollen found in their manure. A random sampling procedure was employed to conduct various vegetation measurements. Animal manure underwent chemical treatment with 10% KOH and was analyzed using the standard acetolysis method to quantify and identify pollen grains from the manure. Paleontological Statistics (PAST) version 4.13 was utilized to perform various statistical analyses on vegetation and pollen to address research inquiries. The study sites demonstrated significant variability in vegetation composition as well as alpha and beta diversity. The eastern Nile sites were distinctly different from the Northwestern sites. The Abuseweid site exhibited the greatest herbaceous diversity and richness, whereas the Buhat site demonstrated the highest dominance of species. Acacia species exhibited extensive distribution across sites. Buhat exhibited the highest percentage of woody cover, whereas the sand dune site demonstrated the lowest percentage. Grass pollen comprised most of the pollen in animal feces samples, with Indigofera pollen prevalent in Al-Salama samples and Amaranthus pollen prevalent in Buhat samples. The diets of goats and camels predominantly comprised grasses, followed by forbs and Acacia, whereas sheep favored Indigofera, followed by Acacia and Tribulus. The correlation between plant species relative density and pollen percentage of Al-Haf, Al-Salama and Buhat was significant and positive. This study offers valuable insights into the assessment of vegetation in grazing areas and the prediction of grazing animals’ diets based on fecal pollen data. This information is crucial for designing effective rangeland management.

Nitrofurantoin is an antibiotic used for treating and preventing urinary tract infections (UTIs). However, major and rare adverse effect of nitrofurantoin induced pulmonary eosinophilia (NIPE), serious condition causes abnormal white blood cell and Immunoglobulin E (IgE) buildup in the lungs, leading to cough, shortness of breath, and fatigue was seen in a patient. This case report describes a patient who developed symptoms of cough, dyspnea, and fatigue after receiving nitrofurantoin for a urinary tract infection over time. Overall, nitrofurantoin is valuable for UTI treatment, but clinicians should be mindful of its adverse effects and adjust doses accordingly.

Given the harmful impact of plastics on organisms’ fitness, one question arises: is compostable material (derived from non-oil sources) any better? Here we assessed the fitness effects of consuming two oil-derived plastics (polyethylene and polystyrene) and one compostable product in insects, utilizing Tenebrio molitor beetles as the study system. Animals were fed during the larval stage either of four different treatments: a) polyethylene + apple/wheat; b) polystyrene + apple/wheat; c) compostable product + apple/wheat; and d) apple/wheat alone. Upon reaching the adult stage, insects were provided with wheat and apple for 7 days, allowed to mate, and lay eggs. We recorded developmental rate and mortality from larvae to pupa, weight and fecundity, and survival probability from one stage to the next. Mortality was higher when animals consumed any type of plastic. The probability of survival was also affected, particularly in the pupal and adult stages. Feeding with any type of plastic oil-derived or compostable plastic led to a reduction in body size and reproductive success (measured as surviving larvae). Notably, in some cases, the group fed with compostable plastic was the most affected. Delays in development at different stages could increase mortality, while the decrease in egg production in females and the reduction in adult size could imply carry-over effects on demography. Perhaps, the additional materials in compostable products imply toxic effects like those caused by plastics. Thus, the effects of compostable products are not any better than those of plastics.

RATIONALE Cryogenic trapping of methane is essential for bulk and clumped isotope analyses, requiring adsorbent materials that enable efficient recovery and preserve isotopic signatures. This study evaluates the performance – capacity, isotopic fractionation, and ease of use – of silica gels, zeolite molecular sieves, and activated carbon under various trapping and desorption conditions. A focus is set on the preservation of methane clumped isotope signatures. METHODS A well-characterized methane reference gas (40 mL) was cryofocused at 77 K in containers filled with silica gels, zeolite molecular sieves (5A and 13X), or activated carbon alongside non-loaded containers. After loading, the containers were warmed in a water bath (21 to 95 °C) for various dwell times. The bulk (𝛿D-CH 4 and 𝛿 13C-CH 4) and clumped (∆ 13CH 3D and ∆ 12CH 2D 2) isotopic composition of the desorbed methane were measured against the untreated reference gas using novel quantum cascade laser absorption spectroscopy (QCLAS). RESULTS The best results were achieved with coarse-grained (1-3 mm) silica gels heated to 50 °C for at least five minutes or at 21 to 22 °C for a minimum of 120 minutes. Elevated desorption temperatures (80 °C to 95 °C) compromised clumped isotope signatures. Although effective for gas trapping, zeolite molecular sieves, and activated carbon introduced significant bulk and clumped isotopic shifts due to catalytic effects and chromatographic isotopologue separation. Methane cryofocused without adsorbents retained its bulk and clumped isotopic composition without significant fractionation. CONCLUSIONS Among the tested adsorbents, silica gels demonstrated superior performance, preserving δ 13C-CH 4, δD-CH 4, ∆ 13CH 3D, and ∆ 12CH 2D 2 values close to or within performance targets while offering high adsorption capacity, reproducibility, and ease of regeneration. Adsorbent-free cryotrapping is a viable alternative for sufficiently large methane volumes, where vapor pressure isotope effects (VPIEs) become negligible. However, cryogenic adsorbents remain indispensable for ensuring isotopic accuracy for small sample volumes and high-precision applications.

This study analyzes the well-posedness and global existence of nonlinear biharmonic partial differential equations (PDEs) of the form ∂ t η , α w + w tt − γ 1 ∆ 2 w − γ 2 ∆ 2 w t + γ 3 w t + γ 4 w = γ 5 ∇ w g ( w ) , involving the generalized Caputo fractional derivative of order 0 < α < 1 in time, where ( x , t ) ∈ Ω × R + . To validate our theoretical findings, we employ a finite difference approach for one-dimensional cases and use the Grünwald–Letnikov approximation. We also address the convergence of this numerical method. AMS Classification: 26A33, 34K37, 31A30, 49K40, 65N06
