Effects of high- versus low-intensity lipid-lowering treatment in patients undergoing serial coronary computed tomography angiography: results of the multi-center LOCATE study.

To evaluate the effects of lipid-lowering medications of different intensities on total, calcified, and non-calcified plaque volumes in patients undergoing serial cardiac computed tomography angiography (CCTA). Individuals with chronic coronary syndromes from 11 centers were included in a retrospective registry. Total, calcified, and non-calcified plaque volumes were quantified and the relative difference in plaque volumes between baseline and follow-up CCTA was calculated. The intensity of lipid-lowering treatment was designated as low, moderate, or high, based on current recommendations. Of 216 patients (mean age 63.1 ± 9.7years), undergoing serial CCTA (median timespan = 824.5 [IQR = 463.0-1323.0] days), 89 (41.2%) received no or low-intensity lipid-lowering medications, and 80 (37.0%) and 47 (21.8%) moderate- and high-intensity lipid-lowering agents, respectively. Progression of total and non-calcified plaque was attenuated in patients on moderate-/high- versus those on no/low-intensity treatment and arrested in patients treated with high-intensity statins or PCSK9 inhibitors (p < 0.001). Halted increase of non-calcified plaque was associated with LDL-cholesterol reduction (p < 0.001), whereas calcified plaque mass and Agatston score increased irrespective of the lipid-lowering treatment (p = NS). The intensity of lipid-lowering therapy robustly predicted attenuation of non-calcified plaque progression as a function of the time duration between the two CCTA scans, and this was independent of age and cardiovascular risk factors (HR = 3.83, 95% CI = 1.81-8.05, p < 0.001). The LOCATE multi-center observational study shows that progression of non-calcified plaques, which have been previously described as precursors of acute coronary syndromes, can be attenuated with moderate-intensity, and arrested with high-intensity lipid-lowering therapy.

Volatile cis-jasmone affects the tri-trophic interactions among the potato plants, the green peach aphid (Myzus persicae), and the parasitoid (Aphidius gifuensis)

New strategies for protecting crops from aphid attacks must be developed. The present study aimed to examine the effect of cis-Jasmone (CJ), an activator of plant defense, on potato plants. Plants were sprayed with an exogenous application of CJ at 12, 24, and 48 h; and the green peach aphid, Myzus persicae Sulzer, and its parasitoid, Aphidius gifuensis, were used to evaluate the tri-trophic interactions of the aphids, parasitoids, and plants. In this work, we examined that the adult M. persicae produced fewer nymphs on CJ-treated plants at 12, 24, and 48 h than on control plants. Furthermore, M. persicae nymphs that fed on CJ-treated plants at 48 h had a lower mean relative growth rate (MRGR). Moreover, the intrinsic rate of population increase (r) was significantly lowered in CJ-treated plants at 12, 24, and 48 h. CJ-treated plants at all time durations showed considerably less settlement of aphid than control plants. In the olfactometer bioassay, the parasitoid exhibited a prolonged duration in the arm treated with volatiles from CJ-treated plants at 12, 24, and 48 h in comparison to the control. Moreover, the salicylic acid and jasmonic acid marker gene expression levels were significantly upregulated by CJ-treatment. Surprisingly, aphids raised on CJ-treated potato plants showed higher transcriptional levels of detoxifying enzymes. The findings of this research will provide new insights into the possible applications of important volatile components like cis-jasmone in integrated pest management systems, in addition to enhancing our comprehension of the ways in which plant volatiles affect the crop community.

Detection of intrinsically disordered peptides by biological nanopore.

Intrinsically disordered protein regions (IDPRs) are pivotal in the regulation of transcription and the facilitation of signal transduction. Because of their multiple conformational states of structure, characterizing the highly flexible structures of IDPRs becomes challenging. Herein, we employed the wild-type (WT) aerolysin nanopore as a real-time biosensor for the identification and monitoring of long peptides containing IDPRs. This sensor successfully identified three intrinsically disordered peptides, with the lengths up to 43 amino acids, by leveraging the unique signatures of blockade current and translocation duration time. The analysis of the binding constant revealed that interactions between the nanopore and peptide are critical for peptide translocation, suggesting that mechanisms beyond mere volume exclusion are at play. Furthermore, by examining the detailed current traces of blockade events, we were able to compare the conformational stabilities of various IDPRs. Our approach can detect the conformational changes of IDPR in a confined nanopore space. These insights broaden the understanding of peptide structural changes under the confined space. This nanopore biosensor showed the potential to study the conformations change of IDPRs, IDPRs transmembrane interactions, and protein drug discovery.

Nonlinear simulations of the peeling-ballooning instability of super H-modes in the HL-3 tokamak

As the newly built tokamak in China, HL-3 will explore high-performance operation scenarios, such as super H-mode. The energy confinement and core parameters in the super H-mode can be much larger than that in the normal H-mode. Based on the pedestal simulation code EPED, the operation space of the super H-mode is obtained in HL-3. Magnetic shear decreases with increasing triangularity; consequently, a super H-mode can be achieved. The threshold of triangularity for accessing a super H-mode in HL-3 is around 0.4. By using BOUT++, a nonlinear simulation study of the pedestal instabilities in the super H-mode equilibrium is executed for the first time. As expected, the low n peeling mode, which can cause much of the energy loss (17%) from the pedestal region, is dominant in the super H-mode. Such a large collapse in the pedestal region would lead to a transition from super H-mode to H-mode. It is crucial to expand the parameter space of the super H-mode or mitigate the edge-localized mode (ELM) size for sustaining the super H-mode operations. The E × B velocity shear is found to play an important role in controlling the ELMs in HL-3. The small E × B velocity shear leads to a large growth rate but results in a small ELM size around the peeling boundary. The ELM size is closely related to both the growth rate of peeling-ballooning mode and the duration time of the linear phase. In contrast, a large E × B velocity shear can stabilize the instabilities near the ballooning boundary. Next, the parameter space of the super H-mode can be enlarged.

The effect of sleep and its restriction on selected inflammatory parameters

Insufficient sleep duration may lead to a series of immune dysfunctions. One of the factors influencing this effect could be physical activity (PA). The study aimed to assess the impact of deprivation of sleep (DS) on selected inflammatory parameters. Seventy-seven participants completed the protocol consisting of polysomnography (PSG) conducted in a sleep laboratory and DS, monitored with an actigraph. PA was assessed with actigraphy, which categorized participants as active or inactive. White blood cells (WBC) values negatively correlated with sleep efficiency based on sleep diaries and PSG parameters (total sleep time, sleep efficiency, and REM duration), but regression analysis showed that WBC depends only on the sleep diary parameter. Granulocytes (GRA) positively correlated with REM latency, and negatively with sleep efficiency. After DS, all participants exhibited an elevated GRA count. The number of WBC and GRA increased also in the active group; inactive participants showed no changes in inflammatory parameters. The overall number of WBC depends primarily on the quality of sleep over a period of several days. Under the influence of sleep deprivation, the number of GRA increases, but the number of leukocytes depends on the level of physical activity during DS.

Neonatal Riga-Fede disease: A systematic review of 84 cases collected over 120 years

Background: Traumatic ulceration of the tongue due to congenital teeth is known as Riga-Fede disease (RFD). The literature on RFD consists largely of anecdotal case reports, thereby lacking valid clinical recommendations. While managing a newborn with RFD complicated by Ludwig’s angina, this knowledge gap was recognized. Therefore, this systematic review was conducted to gain insight into the optimal management and the possible complications of RFD. Methods: A literature search was conducted using PubMed, Google Scholar, and Science Direct, supplemented with African Journals Online, Indmed, and manual searches. Papers published between 1900 and July 2023 in any language were retrieved. Neonates with natal or neonatal teeth and ulceration of the oral mucosa were included. Papers with incomplete data and review articles were excluded. Results: A total of 84 newborns with RFD from 62 published reports (including the case reported herein) were analyzed. Most of the reports were from the Indian subcontinent, and the frequency of reporting has increased since the year 2000. Tongue ulceration in all cases was due to mandibular incisors. There was no significant difference in the median duration of healing between the tooth extraction group (14 days) and the conservative management group (18 days). There was only a very weak positive correlation between the duration of symptoms and healing time, which was statistically insignificant. Conclusion: Healing of mucosal ulcers in RFD is often protracted and does not appear to be influenced by the duration of symptoms or by the modality of treatment. Extraction of the offending teeth is more common (75% of cases) than conservative management, such as grinding (ameloplasty) or resin capping of teeth. RFD is mostly a benign disorder; however, serious complications such as meningitis, Ludwig’s angina, and soft tissue abscesses can rarely occur with Staphylococcus aureus infections.

Diffusion dynamics of an overdamped active ellipsoidal Brownian particle in two dimensions

Shape asymmetry is the most abundant in nature and has attracted considerable interest in recent research. The phenomenon is widely recognized: a free ellipsoidal Brownian particle displays anisotropic diffusion during short time intervals, which subsequently transitions to an isotropic diffusion pattern over longer timescales. We have further expanded this concept to incorporate active ellipsoidal particles characterized by an initial self-propelled velocity. This paper provides analytical and simulation results of diffusion dynamics of an active ellipsoidal particle. The active ellipsoidal particle manifests three distinct regimes in its diffusion dynamics over time. In the transient regime, it displays diffusive behavior followed by a super-diffusive phase, and in the longer time duration, it transitions to purely diffusive dynamics. We investigated the diffusion dynamics of a free particle as well as a particle in a harmonic trap, and a particle subject to a constant field force. Moreover, we have studied the rotational diffusion dynamics and torque production resulting from an external constant force field. Furthermore, our investigation extends to the examination of the scaled average velocity of an ellipsoidal active particle, considering both a constant force field and a one-dimensional ratchet.

Comparative study of different dosages of grain-sized moxibustion on uterine artery blood flow in patients with cold and dampness primary dysmenorrhea.

To observe the differences in the effects of different dosages of grain-sized moxibustion on uterine artery blood flow in patients with cold and dampness primary dysmenorrhea (PD). A total of 60 patients with PD were randomly divided into 3 groups with 20 cases in each group. Acupoints Sanyinjiao (SP6), Diji (SP8) and Xuehai (SP10) were selected in all the 3 groups, and different dosages of grain-sized moxibustion were used (3 moxa cones, 6 moxa cones, 9 moxa cones) respectively. Treatment started 7 days before menstruation for 3 times, lasting for a total of 3 menstrual cycles. The values of uterine artery blood flow parameters including pulsatility index (PI), resistance index (RI), and systolic/diastolic ratio (S/D) were recorded before and after treatment. The visual analog scale (VAS) score and cox menstrual symptom scale (CMSS) score (including severity ［CMSS-S］ and time of duration ［CMSS-T］) were evaluated before treatment, at the end of each menstrual cycle, and one menstrual cycle after treatment. The values of uterine artery blood flow parameters (PI, RI, S/D) after treatment in the 9 moxa cones group were lower than those before treatment, as well as lower than those in the 3 and 6 moxa cones groups after treatment (P<0.05). The VAS scores of the 3 moxa cones group were lower than those before treatment in the first and second cycle (P<0.05). The VAS scores of the 6 and 9 moxa cones groups were lower than those before treatment at each observation point (P<0.05), and were lower than those of the 3 moxa cones group in the third cycle of treatment and follow-up period (P<0.05). And the VAS score of the 9 moxa cones group was lower than that of the 6 moxa cones group during the follow-up period (P<0.05). Compared with the scores before treatment, the CMSS-T scores at each observation point after treatment were lower in the 9 moxa cones group (P<0.05)；the CMSS-T scores in the second and third cycle after treatment, and follow-up period were lower in the 6 moxa cones group (P<0.05), with the CMSS-S scores in the second and third cycle after treatment, and follow-up period lower in the 6 and 9 moxa cones groups (P<0.05). The CMSS-T and CMSS-S scores of the 6 and 9 moxa cones groups were lower than those of the 3 moxa cones group in the third cycle and follow-up period (P<0.05). The CMSS-T and CMSS-S scores of the 9 moxa cones group were lower than those of the 6 moxa cones group during the follow-up period (P<0.05). Grain-Sized moxibustion has dose-effect relationship in the treatment of PD. Compared with 3 and 6 moxa cones groups, 9 moxa cones group has advantages in improving uterine artery blood flow parameters and alleviating dysmenorrhea symptoms in PD patients.

A Descriptive Exploration of Heart Rate Response to Live Professional Irish Dance Performance.

Introduction: Research investigating the physiological demands of dance performance has documented exercise intensity and time spent in work and rest; however, available data are across limited dance genres and often use rehearsal or simulated conditions. Real-time data recorded during live performance with an audience are limited. The aim of the study is to provide a detailed description of the physiological demands of live professional Irish dance performance. Method: The entire Irish dance cast of Riverdance participated in the study (n = 24). Approval was granted by the Institutional Research Ethics Committee. Matinee and evening performances on the first day of a tour were examined in a descriptive, cross-sectional design. Heart rate (HR) monitors worn discretely under costumes recorded data every 5-seconds. Video analysis allowed calculation of time spent in work and rest. All descriptive analyses were split by role (troupe/lead) and sex (male/female). Results: Dancers worked at hard/very hard intensities (mean > 72%, peak > 91% HRmax) for ~3 minutes at a time for 3-9 individual dance numbers. There was a high variation in overall demand experienced by individual dancers due to variation in both duration and intensity of on-stage time, dependent upon their role. Mean total on-stage time was 18.18 ± 5.82 minutes, 19.43 ± 5.80 minutes, 29.71 ± 0.62 minutes, 20.00 ± 0.00 minutes for male troupe, female troupe, male lead, and female lead dancers, respectively. Recovery periods were varied in terms of duration, activity undertaken, and HR response. Conclusion: Individual dance numbers within a professional Irish dance show were high intensity for a short duration when considered in isolation, but overall physiological demand experienced by any one dancer across the entire show varied dependent upon their role and off-stage/recovery practices. Future research investigating the physiological demands of dance performance should ensure analysis accounts for the individual dancer's role and should capture the entire show duration in repeated exposures.

Pyridine Derivatives as Insecticides. Part 5. New Thieno[2,3-b]pyridines and Pyrazolo[3,4-b]pyridines Containing Mainly Ethyl Nicotinate Scaffold and Their Insecticidal Activity toward Aphis gossypii (Glover,1887).

Ethyl 5-cyano-1,6-dihydro-2-methyl-4-(2'-thienyl)-6-thioxonicotinate (A) was synthesized and reacted with ethyl chloroacetate in the presence of sodium acetate or sodium carbonate to give ethyl 5-cyano-6-((2-ethoxy-2-oxoethyl)thio)-2-methyl-4-(2'-thienyl)nicotinate (1a) or its isomeric thieno[2,3-b]pyridine 2a. 3-Aminothieno[2,3-b]pyridine-2-carboxamide 2b was also synthesized by the reaction of A with 2-chloroacetamide. The reaction of 1a with hydrazine hydrate in boiling ethanol gave acethydrazide 3. Heating ester 1a with hydrazine hydrate under neat conditions afforded 3-amino-1H-pyrazolo[3,4-b]pyridine 10. Compounds 2b, 3, and 10 were used as precursors for synthesizing other new thieno[2,3-b]pyridines and pyrazolo[3,4-b]pyridines containing mainly the ethyl nicotinate scaffold. Structures of all new compounds were confirmed by elemental and spectral analyses. Most of the obtained compounds were evaluated for their insecticidal activity toward the nymphs and adults of Aphis gossypii (Glover,1887). Some compounds such as 4, 9b, and 9c showed promising results. The effect of some sublethal concentrations, less than LC50, of compounds 4, 9b, and 9c on the examined Aphis was subjected to a further study. The results demonstrated that exposure of A. gossypii nymphs to sublethal concentrations of compounds 4, 9b, and 9c had noticeable effects on their biological parameters, i.e., nymphal instar duration, generation time, and adult longevity. The highest concentration C1 of all three compounds increased the nymphal instar duration and generation time and decreased adult longevity and vice versa.

Clinical outcomes of guider-assisted osteotomy compared to conventional pendulum-saw osteotomy in open wedge high tibial osteotomy: a propensity score-matched cohort study

PurposeWe developed a novel guider-assisted osteotomy (GAO) procedure to improve the safety of open wedge high tibial osteotomy (OWHTO) and aimed to compare its efficacy and complications with the conventional pendulum-saw osteotomy (PSO).MethodsThis is a retrospective cohort study of patients undergoing either GAO or PSO procedure in the OWHTO to treat varus knee osteoarthritis, who had a minimum of 2 years of follow-up. Patients were propensity score matched (PSM) in a 1:1 ratio based on demographic and clinical data with a caliper width of 0.02. The outcomes assessed involved the hospital for special surgery (HSS) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score, and the Intraoperative and postoperative complications.Results199 patients were included in each group after PSM. The mean duration of follow-up was 38.3 ± 8.9 months. The GAO group had a shorter operation duration (104.5 ± 35.7 vs. 112.1 ± 36.0 min, p = 0.027) and fewer times of intraoperative fluoroscopy (4.2 ± 1.4 vs. 6.0 ± 1.4, p < 0.001). At the last follow-up, clinical scores for knee achieved significant improvements in both GAO and PSO groups: HSS (67.5 ± 10.5 vs. 90.2 ± 7.0, p < 0.001; 69.4 ± 8.2 vs. 91.7 ± 6.8, p < 0.001) and WOMAC (65.7 ± 11.6 vs. 25.2 ± 10.4, p < 0.001; 63.3 ± 12.2 vs. 23.8 ± 9.5, p < 0.001). However, no significant difference was observed between groups for any measures (p > 0.05). In addition, the intraoperative complications (0.5% vs. 3.5%, p = 0.068) and the postoperative bone delayed union and nonunion (1.0% vs. 4.5%, p = 0.032) were marginally or significantly reduced in the GAO versus PSO group.ConclusionGAO demonstrates improvements in intraoperative radiation exposure and complications, with comparable short-term efficacy to PSO, and could be considered a viable alternative in clinical practice.

Efficacy and Safety of Gilteritinib versus Sorafenib as Post-Transplant Maintenance in Patients With FLT3-ITD Acute Myeloid Leukemia

BackgroundFLT3-ITD AML is associated with an increased risk of relapse, leading many patients to receive an allogeneic hematopoietic stem cell transplantation (alloHCT) after induction. Unfortunately, relapse rate after alloHCT remains high and strategies are needed to improve outcomes. Materials and MethodsWe performed a retrospective analysis of adult patients with FLT3-ITD AML who received alloHCT from 6/1/2016 to 12/31/2020 and received gilteritinib (GILT) or sorafenib (SORA)as post-transplant maintenance, outside of a clinical trial. ResultsA total of 55 patients were treated with either GILT (n = 27) or SORA (n = 29) for post-HCT maintenance. One patient was treated with SORA after first alloHCT and GILT after second alloHCT. Patient characteristics were comparable between groups. FLT3 inhibitors were utilized in pre-alloHCT therapy in all but 1 patient. The median duration of time that patients remained on GILT was 385 days (range, 10-804) and on SORA 315 days (range, 3-1777). 1-year PFS and relapse incidence were similar between GILT and SORA; PFS was 66% versus 76% (P = .4) and relapse incidence was 19% versus 24% (P = .6), respectively.Both groups had high incidence of Grade 3-4 hematological toxicity, including neutropenia (45% GILT and 34% SORA) and thrombocytopenia (30% GILT and 52% SORA). Only 44% and 14% patients who received GILT and SORA did not discontinue maintenance, respectively. ConclusionOur results revealed comparable PFS and a similar toxicity profile when SORA and GILT are used as post- HCT maintenance therapy.

Supine Position Popliteal Vein Puncture Under Ultrasound Guidance Is a Feasible and Effective Strategy to Establish Venous Access

This study aims to introduce the clinical application value of popliteal vein puncture in the supine position under ultrasound guidance and compare this method with popliteal vein puncture in the prone position. Endovascular operations for nonthrombotic iliac vein lesions (NIVLs) patients using popliteal vein access were performed during the period from July 2019 to August 2022 at the Zhongshan Hospital (Xiamen), Fudan University and Shanghai Xuhui District Central Hospital. Patients were randomly divided into supine position group and prone position group. All of the patients were punctured under ultrasound guidance. The procedure duration time for popliteal vein puncture, visual analogue score (VAS) scores and postoperative complications were recorded and compared between the two groups. Totally 120 patients were included in this study, in which 60 patients were enrolled in the supine position group, and 60 patients were enrolled in the prone position group. The median procedure time from puncture to iliofemoral venography was 5.97 min (interquartile range 5.78 min -6.03 min) and 28.76min (interquartile range 26.84 min -29.83 min ; p＜0.01）in the supine position and prone position group, respectively. The median time from puncture to access sheath insertion was 5.05 min (interquartile range 4.88 min -5.13 min ) and 5.03 min (interquartile range 4.93 min-5.12 min; p =0.607）in the supine position and prone position group, respectively. The median VAS value was 3 (interquartile range 2-3 ) and 8 (interquartile range 7-9 , p＜0.01）in the supine position and prone position group, respectively. In the supine position group, 1 case of arterial branch injury was observed after operation, and was successfully managed by ultrasound-guided compression. Popliteal vein puncture in the supine position under ultrasound guidance is safe and significantly reduces the overall operation time without changing position, and relieves the discomfort of patients.

Longitudinal Analysis of Hypoglossal Nerve Stimulator Therapy Uptitration Using Cloud-Based Usage Data.

This preliminary study investigates hypoglossal nerve stimulator (HNS) amplitude changes and usage patterns during the initial HNS uptitration period to characterize when patients achieve their therapeutic amplitude. HNS therapy amplitudes, duration, and pause times were examined across the first 4 months of implant use. Average HNS therapy amplitude increased monthly from baseline (0.7 ± 0.3 V) to the first (1.1 ± 0.3 V), second (1.4 ± 0.4 V), third (1.7 ± 0.5 V), and fourth months (1.8 ± 0.5 V) (P < .001). After 4 months, 60% had reached a therapeutic amplitude. Average therapeutic amplitude was greater for patients who did not achieve therapeutic amplitude by month 4 than for those who did (2.6 vs1.6 V; P < .05). Body mass index, baseline apnea-hypopnea index, respiratory disturbance index, and initial HNS amplitude did not differ between the 2 groups. Predictors for therapeutic amplitude and other usage patterns requirefurther investigation.

Tsallis q-Statistics Fingerprints in Precipitation Data across Sicily.

Precipitation patterns are critical for understanding the hydrological and climatological dynamics of any region. Sicily, the largest island in the Mediterranean sea, with its diverse topography and climatic conditions, serves as an ideal case study for analyzing precipitation data, to gain insights into regional water resources, agricultural productivity, and climate change impacts. This paper employs advanced statistical physics methods, particularly Tsallis q-statistics, to analyze sub-hourly precipitation data from 2002 to 2023, provided by the Sicilian Agrometeorological Informative System (SIAS). We investigate several critical variables related to rainfall events, including duration, depth, maximum record, and inter-event time. The study spans two decades (2002-2012 and 2013-2023), analyzing the distributions of relevant variables. Additionally, we examine the simple returns of these variables to identify significant temporal changes, fitting these returns with q-Gaussian distributions. Our findings reveal the scale-invariant nature of precipitation events, the presence of long-range interactions, and memory effects, characteristic of complex environmental processes.

Highly stable mesoporous Co/Ni mixed metal-organic framework [Co/Ni(μ3-tp)2(μ2-pyz)2] for Co (II) heavy metal ions (HMIs) remediation

A bimetallic cobalt/nickel-based metal-organic framework (MOF), [Co/Ni(μ3-tp)2(μ2-pyz)2], denoted as Co/Ni-MOF, has been successfully prepared by a hydrothermal method. The MOF was prepared by incorporating mixed O− and N− donor ligands, specifically terephthalic acid (tp) and pyrazine (pyz). The Mesoporous Co/Ni-MOF was comprehensively characterized using various analytical methods such as XRD, BET, FT-IR, TGA (23 % char yields), SEM, and EDS analyses. The synthesized mesoporous Co/Ni-MOF was then used to absorb Co (II) from aquatic areas efficiently. Several critical parameters, such as the beginning Co (II) concentration (25–150 mg/L), the effect of pH (2–10), the duration of time (5–30 min), and the amount of adsorbent (0.003–0.02 g), were systematically investigated. Remarkably, the Mesoporous Co/Ni MOF displayed a significant adsorption capacity of 372.66 mg g−1 in the optimum conditions, including pH = 6, amount of adsorbent = 0.003 g, duration of time = 25 min, and beginning Co (II) concentration = 150 mg/L. Adsorption data from the experimental studies of the mesoporous Co/Ni MOF are matched based on the non-linear pseudo-first-order (PSO) kinetic model (R2 = 0.9999), and a chemical process is suggested for chemisorption. Furthermore, the adsorption isotherms of Co (II) heavy metal ions (HMIs) are an excellent fit with the non-linear Temkin, indicating that they explain the sorbent/sorbate interactions concerning the heat of adsorption. It is evident from the thermodynamic parameters that adsorption is a spontaneous and favorable exothermic process. These results highlight the promising adsorption performance and potential applications of the mesoporous Co/Ni-MOF as an effective adsorbent for Co (II) elimination from aquatic areas. Four-cycle regeneration studies were the most effective for the Co (II) under study.

Time patterns in online survey completion and offline psychological symptoms among college students in China.

Online psychological surveys allow for swift data collection among college students, thus providing a foundation for psychological interventions, particularly during emergent public health events. However, the association between online survey completion behaviors and offline psychological symptoms has yet to be explored. A large-scale web-based survey was conducted from December 31, 2022, to January 7, 2023, involving 22,624 participants. Psychological symptoms were assessed using standardized measures, while the time taken to complete the survey and the time of completion were recorded by the online survey platform. As the time duration increased, the prevalence of anxiety, depression, insomnia, and PTSD also increased significantly (P for trend < 0.001). The highest odds ratios were observed in the longer duration group. Only a longer duration was significantly associated with PTSD. The time period for completing the questionnaire from 7 p.m. to 10 p.m. was found to be significantly linked with anxiety symptoms and depression symptoms. Conversely, completing the questionnaire at other times was specifically associated with anxiety symptoms and insomnia symptoms. The prolonged duration needed to complete the questionnaire was more closely related to the comorbidity of anxiety, depression, and insomnia than to the comorbidity of those symptoms with PTSD. When questionnaires were completed during other times, specifically referring to the late-night and early morning hours, individuals were more likely to exhibit comorbid symptoms of insomnia. The study identified the specific associations between time durations, time points for completing online survey, and psychological symptoms/comorbidity among college students. Further exploration of their causal relationships and the underlying mechanisms is warranted.

First Reported Series of Cerebral Angiography Performed at an Outpatient Center: Safety and Satisfaction Results.

Ambulatory surgery centers (ASCs) are increasingly common venues for same-day neurosurgical procedures, allowing for cost-effective, high-quality patient care. We present the first and largest series of patients undergoing diagnostic cerebral angiography at an ASC to demonstrate the effectiveness, safety, and efficiency of outpatient endovascular care. We retrospectively reviewed data for consecutive patients who underwent diagnostic cerebral angiography at our ASC between January 1, 2024, and May 29, 2024. Data collected included vascular access approach, procedural duration, turnover time, and periprocedural complications. Using a standardized 2-week postprocedural survey, patients were asked to provide comments and rate their subjective satisfaction from a 1 to 5 scale, with "5" being completely satisfied. All cases were performed with a physician team comprising 1 attending neuroendovascular neurosurgery and 1 neuroendovascular fellow present. Fentanyl and midazolam were administered for conscious sedation in all cases. Among the 67 patients included in this series, the mean procedural duration was 29.4 ± 8.6 minutes. The mean turnover time was 13.7 ± 3.6 minutes. Between transradial (46 of 67 [68.7%]) and transfemoral (21 of 67 [31.3%]) access site approaches, there were no statistically significant differences in mean procedural duration (29.4 ± 8.0 vs 29.2 ± 9.9 minutes, respectively; P = .72) or turnover time (14.0 ± 3.9 vs 12.9 ± 2.8 minutes, respectively; P = .4). No complications occurred periprocedurally or within the 2-week follow-up period. A total of 48 (71.6%) of 67 patients responded to the postprocedural survey, all of whom unanimously reported a score of "5." We found that diagnostic cerebral angiography performed at our ASC was safe and effective for patient care. In addition, all survey respondents (71.6% of those provided the survey) reported highest levels of satisfaction. The integration of neuroendovascular procedures into ASCs potentially offers a cost-effective and highly efficient option in an evolving economic landscape.

S-1-Propenylcysteine Enhances Endurance Capacity of Mice by Stimulating Fatty Acid Metabolism via Muscle Isoform of Carnitine Acyltransferase-1

BackgroundEndurance is an important capacity to sustain healthy lifestyles. Aged garlic extract (AGE) has been reported to exert an endurance-enhancing effect in clinical and animal studies, although little is known about its active ingredients and mechanism of action. ObjectivesThis study investigated the potential effect of S-1-propenylcysteine (S1PC), a characteristic sulfur amino acid in AGE, on the swimming endurance of mice, and examined its mechanism of action by a metabolomics-based approach. MethodsMale Institute of Cancer Research (ICR) mice (6 wk old) were orally administered either water (control) or S1PC (6.5 mg/kg/d) for 2 wk. The swimming duration to exhaustion was measured at 24 h after the final administration. Nontargeted metabolomic analysis was conducted on the plasma samples obtained from mice after 40-min submaximal swimming bouts. Subsequently, the enzyme activity of carnitine acyltransferase-1 (CPT-1) and the content of malonyl-coenzyme A (CoA), acetyl-CoA, and adenosine triphosphate (ATP) were quantified in heart, skeletal muscles, and liver of mice. ResultsThe duration time of swimming was substantially increased in the S1PC-treated mice as compared with the control group. Metabolomic analysis revealed significant alterations in the plasma concentration of the metabolites involved in fatty acid metabolism, in particular medium- or long-chain acylcarnitines in the mice treated with S1PC. Moreover, the administration of S1PC significantly enhanced the CPT-1 activity with the concomitant decrease in the malonyl-CoA content in the heart and skeletal muscles. These effects of S1PC were accompanied by the elevation of the acetyl-CoA and ATP levels to enhance the energy production in those tissues. ConclusionsS1PC is a key constituent responsible for the endurance-enhancing effect of AGE. This study suggests that S1PC helps provide energy during endurance exercise by increasing fatty acid metabolism via CPT-1 activation in the heart and skeletal muscles.
