The effect of control beliefs on the relationship between daily stressors and subjective age in younger adults
Authors: Lee Sofia E. , Neupert Shevaun D. 
Published: March 2024

AbstractExperiencing stress can be associated with feeling and looking older. The goal of this study was to examine daily fluctuations in control beliefs as a potential moderator of the relationship between daily stressors and two indicators of subjective aging in younger adults. Data were collected from 107 younger adults between the ages of 18 and 36 (M = 19.96) who completed an online questionnaire via Qualtrics daily for 9 consecutive days. On Day 1, participants reported demographic information and on Days 2–9, participants reported their daily subjective ages (how old they felt and how old they looked), daily stressors, and perceptions of daily control beliefs. Results from multilevel models revealed that increases in daily stressors were associated with increases in both felt and look age. Although there was no main effect of control beliefs, control beliefs did function as a moderator of the relationship between daily stressors and felt age as well as between daily stressors and look age. Specifically, the aging effect of daily stressors was not significant on days with increases in control beliefs. These results suggest that young adults feel and look older on days when they experience higher levels of stressors and that increases in perceptions of control help to mitigate this effect.

ScopeOxidative stress caused by iron overload tends to result in intestinal mucosal barrier dysfunction and intestinal microbiota imbalance. As a neutral and nonprotein amino acid, L‐Citrulline (L‐cit) has been implicated in antioxidant and mitochondrial amelioration properties. This study investigates whether L‐cit can alleviate iron overload‐induced intestinal injury and explores the underlying mechanisms.Methods and resultsC57BL/6J mice are intraperitoneally injected with iron dextran, then gavaged with different dose of L‐cit for 2 weeks. L‐cit treatment significantly alleviates intestine pathological injury, oxidative stress, ATP level, and mitochondrial respiratory chain complex activities, accompanied by ameliorating mitochondrial quality control. L‐cit‐mediated protection is associated with the upregulation of Glutathione Peroxidase 4 (GPX4) expression, inhibition Nuclear Receptor Coactivator 4 (NCOA4)‐mediated ferritinophagy and ferroptosis, and improvement of gut microbiota. To investigate the underlying molecular mechanisms, Intestinal Porcine Epithelial Cell line‐J2 (IPEC‐J2) cells are treated with L‐cit or AMP‐activated Protein Kinase (AMPK) inhibitor. AMPK signaling has been activated by L‐cit. Notably, Compound C abolishes L‐cit's protection on intestinal barrier, mitochondrial function, and antioxidative capacity in IPEC‐J2 cells.ConclusionL‐cit may restrain ferritinophagy and ferroptosis to regulate iron metabolism, and induce AMPK pathway activation, which contributes to exert antioxidation, ameliorate iron metabolism and mitochondrial quality control, and improve intestinal microbiota. L‐cit is a promising therapeutic strategy for iron overload‐induced intestinal injury.

Published: March 2024

AbstractA photonics‐based terahertz (THz) wireless fronthaul is proposed, and its feasibility is investigated by real‐time demonstration. The proposed wireless fronthaul can be simply integrated into existing fiber‐optic fronthaul, to serve as a complementary or emergency network. An optical signal can be converted into a THz wireless signal by photonics‐based THz‐signal generation technology, utilizing a unitraveling carrier photo‐diode. Following wireless transmission, the THz wireless signal is reconverted to an optical signal by using a Schottky‐barrier diode and an optical transmitter. To investigate the feasibility of our proposed concept, real‐time transmission over a 100 m‐equivalent configuration is demonstrated with 24.33 Gb/s common public radio interface option 10 signals, at a carrier frequency of 275 GHz. The latency added by the proposed wireless fronthaul was measured to be few 100 ns, which is negligibly lower than the wireless transmission latency required by 6G key performance indicator.

AbstractTo assess the performance of microwave brain imaging (MWBI) systems, an anthropomorphic multifunctional head phantom with long life, low cost, and reliable dielectric properties over the intended frequency range is a principal requisite. A solid head model has been developed using a mold casting method, incorporating graphite, aluminum oxide, carbon black powder, and brass powder with epoxy/hardener. Four healthy solid brain tissues consisting of skin, skull, gray matter, and white matter are fabricated to mimic realistic head tissue properties along with cerebrospinal fluid. The constructed head model incorporates four cavities of varying sizes and positions, designed to accommodate healthy or unhealthy cores, thereby simulating diverse stroke scenarios without necessitating separate healthy and unhealthy models. Utilizing a single‐head model preserves dielectric properties during comparative analysis (healthy/unhealthy), except for core components. Tissue properties were measured twice, three months apart, showing good agreement between theoretical and measured results.

Published: March 2024

AbstractAimsStatins are widely used to treat dyslipidemia and have been shown to reduce the risk of ischemic heart disease and cerebrovascular disease. The effects of statins on ischemia‐induced overactive bladder (OAB) and the associated mechanisms were investigated in a rat model of chronic pelvic ischemia.MethodsA pelvic ischemia model was created by iliac arterial injury (AI) and a high‐fat diet using male Sprague−Dawley rats. Rats were assigned to 3 groups: control group, AI group, and AI + statin group. The control group underwent sham operation and was fed a normal diet. The AI group underwent AI surgery and was fed a high‐cholesterol diet. The AI + statin group was administered a statin for 4 weeks. Cystometry was performed for 8 weeks after surgery. Blood flow was evaluated by laser meter. Thickness of the iliac arteries was measured, and microvascular density in the lamina propria was evaluated by immunostaining for CD31. Expressions of inflammatory cytokines in the bladder were measured by real‐time PCR.ResultsCystometry showed a significantly shorter voiding interval and lower bladder capacity in the AI group than in the control group. The AI + statin group showed improvement of these findings. The AI group showed decreased bladder blood flow, increased iliac arterial wall thickening, and decreased microvascular density compared to the control group. Statin administration improved blood flow. Iliac arterial wall thickening was suppressed, and microvascular density was increased by statin administration, though not significantly. Real‐time PCR showed significantly higher expressions of inflammatory cytokines (IL‐6, IL‐8, and TNF‐α) in the AI group than in the control group, and IL‐6 and IL‐8 expressions were lower in the AI + statin group than in the AI group.ConclusionsThe present results suggest that statins are effective in OAB caused by arteriosclerosis and ischemia. The mechanism of their effects involves improved bladder blood flow and decreased bladder inflammation.

AbstractAimsTo assess and compare 30‐day perioperative adverse events following suburethral sling surgery using synthetic mesh, autologous rectus fascia, and autologous fascia lata in women.MethodsThis was a retrospective cohort study of patients who underwent fascial or synthetic sling placement for stress urinary incontinence between 2008 and 2021 using the American College of Surgeons' National Surgical Quality Improvement Program database. Current Procedural Terminology codes were used to identify patients undergoing each type of sling procedure. Multivariable regression analysis with stepwise regression was used to assess the odds of composite adverse events (e.g., urinary tract infection, surgical site infection, pulmonary embolism, and other reportable events) between cohorts.ResultsOf the 41 533 female patients who underwent isolated suburethral sling placement without concurrent procedures, 41 292 (99.4%) received a synthetic mesh sling, and 241 (0.6%) received an autologous facial sling. In the fascial sling cohort, 160 (66.4%) underwent rectus fascia harvest and 81 (33.6%) underwent fascia lata harvest. Sling surgeries involving autologous fascia were associated with increased odds of adverse events compared to those involving synthetic mesh, even after adjusting for confounders (adjusted odds ratio [aOR]: 3.63, 95% confidence interval [CI]: 2.56–5.15). Compared to fascial slings from rectus fascia, slings from fascia lata were associated with increased odds of composite adverse events (aOR: 2.11, 95% CI: 1.03–4.04). However, with the exclusion of urinary tract infections, the adverse event rate was similar between slings using the two fascial harvest techniques (aOR: 1.93, 95% CI: 0.81–4.63).ConclusionsIn this retrospective database study, suburethral sling surgeries using autologous fascia were independently associated with a 3.6‐fold increase in odds of 30‐day perioperative adverse events compared to sling surgeries using synthetic mesh.

AbstractAlthough hyperpolarized (HP) 129Xe ventilation MRI can be carried out within a breath hold, it is still challenging for many sick patients. Compressed sensing (CS) is a viable alternative to accelerate this approach. However, undersampled images with identical sampling ratios differ from one another. Twenty subjects (n = 10 healthy and n = 10 patients with asthma) were scanned using a GE MR750 3 T scanner, acquiring fully sampled 2D multi‐slice HP 129Xe lung ventilation images (10 s breath hold, 128 × 80 (FE × PE—frequency encoding × phase encoding) and 16 slices). Using fully sampled data, 500 variable‐density Cartesian random undersampling patterns were generated, each at eight different sampling ratios from 10% to 80%. The parallel imaging and compressed sensing (PICS) command from BART was employed to reconstruct undersampled data. The signal to noise ratio (SNR), structural similarity index measurement (SSIM) and sidelobe to peak ratio of each were subsequently compared. There was a high degree of variation in both SNR and SSIM results from each of the 500 masks of each sampling rate. As the undersampling increases, there is more variation in the quantifying metrics, for both healthy and asthmatic individuals. Our study shows that random undersampling poses a significant challenge when applied at sampling ratios less than 60%, despite fulfilling CS's incoherency criteria. Such low sampling ratios will result in a large variety of undersampling patterns. Therefore, skipped segments of k‐space cannot be allowed to happen randomly at low sampling rates. By optimizing the sampling pattern, CS will reach its full potential and be able to be applied to a highly undersampled 129Xe lung dataset.
L2$$ {L}_2 $$‐gain analysis and fault‐tolerant control for nonlinear discrete‐time switched systems with time‐varying delay and actuator saturation
Authors: Guo Hu , Li Huiju , Zhang Xinquan 
Published: March 2024

AbstractThe ‐gain analysis and fault‐tolerant control of a class of uncertain nonlinear discrete‐time switched systems with time‐varying delay and actuator saturation are studied by using the multiple Lyapunov functions method. The fault‐tolerant state feedback controllers and the switching law are designed such that the closed‐loop system with actuator failures satisfies the disturbance attenuation performance indicator. The problem of estimating the capacity of admissible disturbance is transformed into a constrained optimization problem to ensure that the state trajectory of the closed‐loop system is bounded under the action of external disturbances. The upper bound of restricted ‐gain is estimated by solving constrained optimization problems. Then, when the fault‐tolerant controller can be regard as the design variable, the optimization problems above are adjusted for solving control synthesis problems. Finally, the numerical example is given to verify the effectiveness of the design method.

Published: March 2024

AbstractObjectiveTo compare surgical and nonsurgical definitive treatment in cT4b major salivary gland cancer (MSGC).Study DesignRetrospective cohort study.SettingThe 2004 to 2019 National Cancer Database.MethodsThe NCDB was queried for patients with cT4b MSGC (N = 976). Patients undergoing definitive treatment with (1) surgical resection + adjuvant therapy, (2) radiotherapy (RT) alone, or (3) chemoradiotherapy (CRT) were included in Kaplan‐Meier and Cox survival analyses.ResultsOf 219 patients undergoing definitive treatment, 148 (67.6%) underwent surgical resection + adjuvant therapy and 71 (32.4%) underwent RT or CRT. There were no documented mortalities within 90 days of surgical resection. Tumor diameter and nodal metastasis were associated with decreased odds of undergoing definitive treatment (P < 0.025). Patients with positive surgical margins (PSM) had higher 5‐year overall survival (OS) than those undergoing definitive RT or CRT (48.5% vs 30.1%, P = 0.018) and similar 5‐year OS as those with negative margins (48.5% vs 54.0%, P = 0.205). Surgical resection + adjuvant therapy (adjusted hazard ratio: 0.55, 95% confidence interval [CI]: 0.37‐0.84) was associated with higher OS than definitive RT or CRT (P < 0.025). A separate cohort of 961 patients with cT4a tumors undergoing surgical resection + adjuvant therapy was created; cT4a and cT4b (hazard ratio: 1.02, 95% CI: 0.80‐1.29, P = 0.896) tumors had similar OS.ConclusionA minority of patients with cT4b MSGC undergo definitive treatment. Surgical resection + adjuvant therapy was safe and associated with higher OS than definitive RT or CRT, despite high rate of PSM. In the absence of clinical trial data, appropriately selected patients with cT4b MSGC may benefit from surgical resection.

AbstractObjectiveAssess the safety of ambulatory surgery performed for obstructive sleep apnea.Study DesignRetrospective chart review.SettingTertiary care hospital.MethodsDemographic data including age, gender, race, body mass index, insurance status, socioeconomic status, and distance traveled for surgery was collected, as well as comorbidities, and apnea‐hypopnea index (AHI). Outcome variables included continuous positive airway pressure reinitiation, planned/unplanned postoperative admission, emergency department (ED) presentation, or readmission within 7 and 14 days of surgery.ResultsA total of 601 patients were included, who underwent sleep surgery between 2017 and 2022. The median age was 55 years [interquartile range: 19]. A total of 437 patients (73%) were male, 502 (84%) were Caucasian, and the median distance traveled was 20 miles [27]. The median AHI was 27.1 [26]. A total of 286 hypoglossal nerve stimulators, 12 tonsillectomies, 160 expansion sphincteroplasties (ESP), and 201 nasal procedures were performed. There were 9 (1%) planned and 23 (4%) total admissions postoperatively. Sixteen patients (2%) presented to ED within 7 days, and 22 (3%) within 14 days. Nine (1%) were readmitted within 7 days, and 12 (2%) within 14 days. There were significantly more planned admissions, unplanned admissions, ED presentations, and readmissions for ESP. There were no significant differences in demographic or clinical data between patients who underwent single versus multiple surgeries.ConclusionOutpatient sleep surgery is generally safe. Close postoperative monitoring is necessary and overnight observation should be considered in those with very severe sleep apnea and/or significant comorbidities. The distance a patient travels should also be considered for overnight admission.

AbstractObjectiveWe aim to evaluate the role of elective neck dissection (END) and adjuvant radiation on survival in N0 high‐grade mucoepidermoid carcinoma (MEC).Study DesignRetrospective cohort study.SettingNational Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) database.MethodsAll patients diagnosed with high‐grade MEC with node‐negative disease (N0) from 2004 to 2018 were included. Demographic, clinicopathologic, treatment, and outcomes were analyzed. Kaplan‐Meier survival curves were used to evaluate 5‐year disease‐specific survival (DSS) and 5‐year overall survival (OS). Multivariate Cox regression analysis was used to control for confounders.ResultsA total of 310 patients with high‐grade MEC and N0 (clinical and pathologic) disease were identified. The parotid was the most common primary site (266, 86%). Of included patients, 133 (42.9%) were T3‐T4 tumors and 212 (68%) received adjuvant radiation. END was performed on 223 (71.9%) of cases. END in T3‐T4 high‐grade MEC led to significant improvements in DSS (74.3% vs 34.0%, P < .01) and OS (55.2% vs 20.5%, P < .01) as compared to no END. Subanalysis shows that in patients who received neck dissections and were pathologic N0, adjuvant radiation had no impact on DSS (84.0% vs 72.1%, P = .45) and OS (52.1% vs 55.8%, P = .91). Benefits persisted when controlling for confounders using multivariate Cox proportional regression.ConclusionPatients with T3‐T4 high‐grade MEC who underwent END and found to be pathologically node‐negative (pN0) had significantly improved 5‐year DSS and 5‐year OS than patients who were cN0 and did not undergo END. Importantly, although 68% of patients received adjuvant radiation, we show no benefit of this treatment modality on outcomes in pN0 high‐grade MEC.

Published: March 2024

AbstractIn this review, fundamental aspects of the electrochemical intercalation of anions into graphite have been first summarized, and then described the electrochemical preparation of covalent‐type GICs and application of graphite as the cathode of dual‐ion battery. Electrochemical overoxidation of anion GICs provides graphite oxide and covalent‐fluorine GICs, which are key functional materials for various applications including energy storage devices. The reaction conditions to obtain fully oxidized graphite has been mentioned. Concerning the application of graphite for the cathode of dual‐ion battery, it stably delivers about 110 mA h g−1 of reversible capacity in usual organic electrolyte solutions. The combination of anion and solvent as well as the concentration of the anions in the electrolyte solutions greatly affect the performance of graphite cathode such as oxidation potential, rate capability, cycling properties, etc. The interfacial phenomenon is also important, and fundamental studies of charge transfer resistance, anion diffusion coefficient, and surface film formation behavior have also been summarized. The use of smaller anions, such as AlCl4−, Br− can increase the capacity of graphite cathode. Several efforts on the structural modification of graphite and development of electrolyte solutions in which graphite cathode delivers higher capacity were also described.

Published: March 2024

AbstractNanomaterials based on metal oxides, especially Cu2O, have received much attention in recent years due to the many unique properties of the surface plasmon resonance they provide. The report presented the co‐precipitation method, a simple preparation method to produce Cu2O oxide particles. In addition, to improve the unique antibacterial properties of Cu2O, a proposed method is to attach Ag nanoparticles to the surface of Cu2O particles. The Cu2O and Cu2O−Ag particles were synthesized based on redox reactions using ascorbic acid (LAA) as a reducing agent. Moreover, in this experiment, two surfactants, polyethylene glycol 6000 (PEG 6000) and sodium dodecyl sulfate (SDS), were added during the manufacturing process to create particle samples and particle combinations with better properties than the original sample. Changes in the characteristics and properties of particle samples are determined by many different physical and chemical methods such as ultraviolet‐visible spectroscopy (UV‐Vis), infrared spectroscopy (IR), noise X‐ray radiation (XRD), scanning electron microscope (SEM), dynamic light scattering (DLS), energy dispersive X‐ray spectroscopy (EDS), and transmission electron microscopy (TEM). Finally, the activity against bacteria, including E. coli and S. aureus, was also tested using the agar well diffusion method to determine the zone of inhibition. The results improved the particle size value, which decreased by half to 200 nm when two additional surfactants, PEG and SDS, were added. In addition, the antibacterial ability has also been shown to increase significantly when the diameter of the bacterial inhibition zone increased significantly, reaching values of 20 mm (Cu2O/Ag/SDS) and 32 mm (Cu2O/Ag/PEG) for the E. coli bacterial strain. The initial test sample was only about 14 mm in size. The S. aureus bacterial strain also had a similar improvement trend after adding Ag to the Cu2O surface with the appearance of two surfactants, SDS and PEG. The inhibition zone diameter values reached the optimal value at 36 mm in the Cu2O/Ag/PEG particle combination sample compared to only the initial 26 mm in the Cu2O particle sample. Finally, the particle samples are added to the acrylic emulsion paint film to evaluate the changes. Positive results were obtained, such as improvement in adhesion (1.22 MPa), relative hardness (240/425), and sand drop resistance (100 L/mil) in the Cu2O/Ag/PEG particle combination sample, which showed the correctness and accuracy of the research.
