AbstractSkeletal muscle atrophy is the reduction in muscle mass and function caused by an imbalance in protein synthesis and degradation. Inflammation has been shown to accelerate protein degradation during periods of muscle inactivity. We investigated the potential therapeutic effects of beetroot extract (BRE) in reducing inflammation and oxidative stress to prevent muscular atrophy after a short period of immobilization. We divided 36 male BALB/c mice into three groups: control, muscular atrophy mice, and muscular atrophy mice treated with BRE (n = 12). Each group was further divided into two subgroups: (1) 7‐day immobilization and (2) 10‐day recovery. BRE was administered orally at a dose of 300 mg/kg for 17 days. We assessed the anti‐inflammatory and antioxidative effects of BRE using ELISA and RT‐PCR assays. Hematoxylin–eosin staining was used to measure the cross‐sectional area (CSA) of muscle fibers, and grip strength tests were performed to assess muscle strength. BRE administration increased muscle weight, CSA, and grip strength in mice with immobilization‐induced muscle atrophy. It also suppressed inflammation and oxidative stress biomarkers in atrophic muscle fibers. Higher nitrate levels and lower Troponin I (TnI) concentrations were observed in the BRE‐treated group, indicating improved muscle function and structure. These findings suggest that BRE may have therapeutic benefits in improving muscle mass and function and warrant further studies in humans, particularly in individuals with low physical activity levels.

AbstractCalcium (Ca) is a vital nutrient essential for structural development and signal transmission in both plants and animals. In humans, inadequate calcium intake has been correlated with various diseases, including osteoporosis, cardiovascular and cerebrovascular diseases, and cancer. In areas where plants serve as a main dietary source, calcium intake is significantly lower than the recommended adequate intake, notably in low‐ and middle‐income countries (LMICs). Exploring the connections between calcium consumption and cardiovascular disease (CVD) and cancer has significant implications for public health, given that these two conditions are the primary contributors to global mortality. This study conducted a systematic review of existing literature to assess the evidence regarding calcium intake and its effect on blood pressure control, stroke prevention, and the controversial association with myocardial infarction. Furthermore, the preventive effect of calcium intake on tumor development, particularly in cancer prevention, was discussed. The study explores the potential of agronomic biofortification as a key strategy to enhance plant‐based dietary calcium density and improve human health. By advocating for the incorporation of calcium‐rich plants and plant‐derived products, alongside appropriate calcium supplementation, the study emphasizes the economic and practical benefits of plants as a calcium source. This approach is aligned with global dietary patterns and socioeconomic disparities. The review also highlights the need for further research to better understand the mechanisms through which agronomic biofortification can increase dietary calcium intake and reduce the risks of CVD and cancer associated with calcium deficiency. Ultimately, this study aims to deepen our understanding of the complex relationship between calcium intake and health.

ABSTRACTTo reconstruct the detailed location of proto‐Japan around northeastern Gondwana during the early Palaeozoic, this article presents detrital zircon U–Pb age spectra for lower Palaeozoic metamorphic complexes and Silurian–Devonian strata from the western margin of the South Kitakami belt in northeast Japan. Psammitic and siliceous schists have youngest age peaks ranging from the Ordovician (479–458 Ma) to early Silurian (ca. 439 Ma). Sandstones have youngest age peaks varying from the early Silurian (ca. 435 Ma) to Late Devonian (370–360 Ma). The U–Pb age spectra exhibit major peaks at 510–500, 480–470, and 450–440 Ma. Excluding the Upper Devonian sandstones, significant age peaks occur at 650–550 and 1300–900 Ma. These data can be interpreted as a Pacific Gondwana signature, indicating a tectonic association with the Terra Australis Orogen that developed along the northeastern Gondwanan margin and Paleo‐Pacific Ocean, extending from eastern Australia (i.e., the Thomson, Lachlan, and Delamerian orogens) to Antarctica (i.e., the Ross Orogen). In northeast Asia, the Pacific Gondwana detrital zircons and 480–470 Ma zircons occur in the Bainaimiao arc belt along the northern margin of the North China Craton and in the Jiangyu continental arc in the Jilin area. The magmatic arcs of proto‐Japan and these regions were part of the Terra Australis Orogen during the Ordovician–early Silurian. A decrease in the proportion of Pacific Gondwana detrital zircons in Upper Devonian strata may be due to multistage trench retreat, such as that recognized in the Tasmanides in eastern Australia, which corresponds to the northern Terra Australis Orogen.

AbstractObjectivesOur study aimed to evaluate the effect of superior hypogastric nerve plexus (SHNP) block in postoperative pain management in the first 24 h after minimally invasive gynecological (MIG) surgeries.MethodsWe conducted a double‐blinded, randomized controlled trial in the Department of Obstetrics and Gynecology at a tertiary care centre from May 1, 2023 to September 30, 2023 in women undergoing major MIG surgeries. At the completion of the surgery, women were randomized to the intervention group who received SHNP block with ropivacaine 10 mL (0.75%) before port removal, whereas no intervention was taken in the control group. The extubation time was noted, and the pain score was assessed after 1, 2, 6, 12, and 24 h of extubation in the postoperative period using the visual analog scale (VAS). Statistical analysis was done, with a significance level of 0.05, to test the differences between the two groups.ResultsA total of 64 patients were randomly allocated to intervention and control groups. The median pain score was lower at 1 and 2 h post‐extubation and comparable between the two groups at 6, 12, and 24 h. The surrogate markers that is need for additional analgesia and duration of stay did not differ significantly in the two groups, with P‐values of 0.08 and 0.943, respectively.ConclusionAlthough the SHNP group experienced considerably lower immediate postoperative pain levels in the initial hours following extubation, the impact of this benefit remains uncertain in the longer postoperative period. The effectiveness of this modality for pain control needs further study, particularly at later postoperative hours.

BackgroundPrimary open‐angle glaucoma (POAG), a leading cause of irreversible blindness, is associated with neurodegeneration in the visual pathway, but the underlying pathophysiology remains incompletely resolved.PurposeTo characterize macro‐ and microstructural white matter abnormalities in optic tract (OT) and optic radiation (OR) of POAG.Study typeProspective.PopulationsA total of 34 POAG patients (21 males, 13 females) and 25 healthy controls (HCs) (16 males, nine females).Field Strength/Sequence3 T; multiband spin‐echo echo planar diffusion spectrum imaging (DSI).AssessmentWe compared multiple morphology metrics, including volume, area, length, and shape metrics, as well as diffusion metrics such as diffusion tensor imaging (fractional anisotropy [FA], mean diffusivity, radial diffusivity, and axial diffusivity), mean apparent propagator (mean squared displacement, q‐space inverse variance, return‐to‐origin probability, return‐to‐axis probabilities [RTAP] and return‐to‐plane probabilities, non‐Gaussianity, perpendicular non‐Gaussianity, parallel non‐Gaussianity), and neurite orientation dispersion and density imaging (intracellular volume fraction, orientation dispersion index [ODI], and isotropic volume fraction of the OT and OR).Statistical TestsStatistical comparisons and classifications employed linear mixed model and logistic regression. Diagnostic performance was assessed using area under the receiver operating characteristic curve (AUC). P‐value <0.05 was statistically significant.ResultsMorphology analysis in POAG revealed a lower span in the OR (29.43 ± 2.30 vs. 30.59 ± 2.01, 3.8%) and OT (19.73 ± 2.21 vs. 20.68 ± 1.37, 4.6%), and a higher curl (3.03 ± 0.22 vs. 2.90 ± 0.16, 4.5%) in OT. Diffusion metrics revealed lower mean FA (OR: 0.328 ± 0.03 vs. 0.340 ± 0.018, 3.5%; OT: 0.255 ± 0.022 vs. 0.268 ± 0.018, 4.9%) and lower mean RTAP (OR: 5.919 ± 0.529 vs. 6.216 ± 0.489, 4.8%; OT: 4.089 ± 0.402 vs. 4.280 ± 0.353, 4.5%), with higher mean ODI in the OT (0.448 ± 0.029 vs. 0.433 ± 0.025, 3.5%). Combined models, incorporating these MRI metrics, effectively discriminated POAG from HCs, achieving AUCs of 0.84 for OR and 0.83 for OT.Data ConclusionsDSI‐derived morphology and diffusion metrics demonstrated macro‐ and micro abnormalities in the visual pathway, providing insights into POAG‐related neurodegeneration.Level of Evidence2Technical EfficacyStage 3

AbstractJoint injury can lead to articular cartilage damage, excessive inflammation, and post‐traumatic osteoarthritis (PTOA). Collagen is an essential component for cartilage function, yet current literature has limited understanding of how biochemical and biomechanical factors contribute to collagen loss in injured cartilage. Our aim was to investigate spatially dependent changes in collagen content and collagen integrity of injured cartilage, with an explant model of early‐stage PTOA. We subjected calf knee cartilage explants to combinations of injurious loading (INJ), interleukin‐1α‐challenge (IL) and physiological cyclic loading (CL). Using Fourier transform infrared microspectroscopy, collagen content (Amide I band) and collagen integrity (Amide II/1338 cm−1 ratio) were estimated on days 0 and 12 post‐injury. We found that INJ led to lower collagen content near lesions compared to intact regions on day 0 (p < 0.001). On day 12, near‐lesion collagen content was lower compared to day 0 (p < 0.05). Additionally, on day 12, INJ, IL, and INJ + IL groups exhibited lower collagen content along most of tissue depth compared to free‐swelling control group (p < 0.05). CL groups showed higher collagen content along most of tissue depth compared to corresponding groups without CL (p < 0.05). Immunohistochemical analysis revealed higher MMP‐1 and MMP‐3 staining intensities localized within cell lacunae in INJ group compared to CTRL group on day 0. Our results suggest that INJ causes rapid loss of collagen content near lesions, which is intensified on day 12. Additionally, CL could mitigate the loss of collagen content at intact regions after 12 days.

AbstractObjectiveTo identify predictors associated with loss and recovery of smell and taste after COVID‐19 infection.MethodsThe Integrated Public Use Microdata Series (IPUMS) 2021 National Health Interview Series (NHIS) database was used to analyze factors associated with loss and recovery of smell and taste in respondents who had a previous COVID‐19 infection. Significant variables from univariate analysis were included in a stepwise backward regression model to identify independent predictors.ResultsOf the 3844 individuals who answered yes to having contracted COVID‐19, 51.1% and 48.9% reported losing smell and taste, respectively. 95.7% recovered smell and 97% recovered taste. Predictors associated with higher odds of reporting a loss of smell included younger age (odds ratio [OR] 0.98; 95% confidence interval [CI] 0.98–0.99), female sex (OR 1.38; CI 1.17–1.63), use of e‐cigarettes (OR 1.59; CI 1.25–2.02), and Mexican ethnicity (OR 1.61; CI 1.22–2.11). Predictors of taste loss were younger age (OR 0.98; CI 0.98–0.99), female sex (OR 1.31; CI 1.08–1.58), and higher BMI (OR 1.02; CI 1.00–1.04). Female sex was associated with decreased odds of reporting a recovery of smell (OR 0.74; CI 0.59–0.92) and taste (OR 0.54; CI 0.42–0.69). Black/African American race (OR 1.44; CI 1.03–2.03) and non‐Mexican Hispanic ethnicities (OR 1.55; CI 1.02–2.34) were associated with an increased likelihood of reporting the recovery of smell.ConclusionVarious factors may be associated with the loss and recovery of smell and taste after COVID‐19 infections. Clinicians may use this information to better counsel patients with these symptoms.Level of evidence4.

AbstractArtificial saturable absorbers (SA) are nonlinear optical devices widely employed in mode‐locked lasers. Among the artificial SAs are nonlinear polarization evolution (NPE) and nonlinear amplifying loop mirrors that can work in either figure‐of‐eight (Fo8) or figure‐of‐nine (Fo9) laser cavities. The NPE technique is highly sensitive to environmental perturbations. Both Fo8 and Fo9 laser cavities exhibit a higher environmental stability than the NPE technique. Here the recent advances of the Fo9 laser cavity, with a focus on the pulse formation mechanisms and the role of different cavity parameters that can enable ultrafast mode‐locking analyses are discussed. Besides, the recent development of using the Fo9 laser cavity to generate high‐energy rectangular laser pulses through either dissipative soliton resonance or noise‐like pulse regimes is also reviewed. In conclusion, the current issues and challenges of pulse formation through the Fo9 laser cavity are highlighted and recommendations for future research directions are proposed. This review is expected to provide a deeper insight into the Fo9 laser cavity as the next generation of artificial SA with interesting cavity structures, laser features, and output performances.

AbstractTympanic membrane (TM) perforation is a serious ear discomfort that can cause hearing loss and make the middle ear vulnerable to infections. In this study, a unique TM patch is designed to mimic the structure of the natural eardrum for tissue engineering of TM perforations. Gelatin methacryloyl (GelMA)‐based TM patches are equipped with microneedles (MNs) to better adhere to the perforation site and developed using the digital light processing (DLP) based 3D printing technique. To impart biofunctionality to the 3D‐printed patches, their surfaces are coated with gentamicin (GEN) loaded poly(vinyl alcohol) (PVA) nanoparticles (NPs) using the Electrohydrodynamic Atomization (EHDA) method. The physicochemical characteristics, drug release behaviour, antimicrobial properties and biocompatibility of GelMA, PVA NP‐coated GelMA, and GEN@PVA NP‐coated GelMA patches are investigated. Morphological analyses confirmed that 3D‐printed GelMA patches are fabricated in desired sizes and geometries and successfully coated with NPs. In vitro antibacterial tests revealed that GEN@PVA NP‐coated GelMA patches have antibacterial activities against Staphylococcus aureus and Escherichia coli. Moreover, in vitro cell culture studies indicated that all GelMA‐based patches have no cytotoxic effect on L929 mouse fibroblast cells. Considering all, these specially designed biofunctional 3D‐printed GelMA patches can be an effective therapeutic approach for repairing TM perforations.
Tensile and Elastocaloric Properties of Natural/Devulcanized Waste Rubber Blends

Published: September 2024

AbstractThe need for eco‐friendly cooling materials and material recycling are two urgent challenges to address. In this paper, the role of the ground tyre rubber treatment (cryo‐grinding and devulcanization) is investigated on the tensile and elastocaloric properties of Natural rubber (NR)/ ground tyre rubber (GTR). The GTR particles that are sieved (<63µm) and devulcanized by microwave irradiation (1 min at 800Watts) exhibit a low network chain density (0.53 × 10−4 mol.cm−3) resulting from crosslinks breakage and rubber chains scission, as supported by FTIR showing a decrease of S─S, C─S, and C─C bonds. The NR/GTR blends show a high elastocaloric effect as compared to the pristine NR, which can be ascribed to the high content of carbon black in the GTR (52 wt.%) and also the high level of devulcanization of the GTR. NR/GTR blends reach a heating of +8 °C and a cooling of >−6 °C, resulting in a material's coefficient of performance COPmat = 2.8–3 compared to 2.6 for the pristine NR. The concomitant effect of cryogrinding and microwave devulcanization is proposed as a way to improve the tensile and elastocaloric properties of natural rubber/waste rubber blends for their possible integration into elastocaloric devices for heating/cooling applications.

AbstractCotton fabrics with the main constituent of cellulose, which is hydrophilic, bacterial infected, and flammable, are in urgent need of functionalization as a kind of widely applied material. To address these issues, in this work, modified polyelectrolyte complex (MPEC) coatings with polyethylenimine (PEI), polyphosphate (APP), and perfluorodecyltrichlorosilane modified PEI (PFTS‐PEI) are prepared to construct multi‐functionally gradient MPEC coatings on cotton fabrics. Stability and synergistic effects on hydrophobicity, antibacterial activity, and flame retardancy in this system have been studied. Notably, PFTS‐PEI with fluorine and silicone elements are confirmed to provide hydrophobicity and durability for MPEC coatings, which not only has no negative effect on other functions but also makes some improvement in antibacterial activity. This MPEC‐treated cotton fabric finally has an antibacterial rate against S. aureus and E. coli of 99.9% and 96.9%, limiting oxygen index of 28.5% and water contact angle of 118°, which can be almost maintained after 20 times washing. The modified PEC will provide an efficient strategy to achieve durable multi‐functions on cellulose‐based fabrics.

Published: September 2024

AbstractBackgroundReference dosimetry in ultra‐high dose rate (UHDR) beamlines is significantly hindered by limitations in conventional ionization chamber design. In particular, conventional chambers suffer from severe charge collection efficiency (CCE) degradation in high dose per pulse (DPP) beams.PurposeThe aim of this study was to optimize the design and performance of parallel plate ion chambers for use in UHDR dosimetry applications, and evaluate their potential as reference class chambers for calibration purposes. Three chamber designs were produced to determine the influence of the ion chamber response on electrode separation, field strength, and collection volume on the ion chamber response under UHDR and ultra‐high dose per pulse (UHDPP) conditions.MethodsThree chambers were designed and produced: the A11‐VAR (0.2–1.0 mm electrode gap, 20 mm diameter collector), the A11‐TPP (0.3 mm electrode gap, 20 mm diameter collector), and the A30 (0.3 mm electrode gap, 5.4 mm diameter collector). The chambers underwent full characterization using an UHDR 9 MeV electron beam with individually varied beam parameters of pulse repetition frequency (PRF, 10–120 Hz), pulse width (PW, 0.5–4 µs), and pulse amplitude (0.01–9 Gy/pulse). The response of the ion chambers was evaluated as a function of the DPP, PRF, PW, dose rate, electric field strength, and electrode gap.ResultsThe chamber response was found to be dependent on DPP and PW, and these dependencies were mitigated with larger electric field strengths and smaller electrode spacing. At a constant electric field strength, we measured a larger CCE as a function of DPP for ion chambers with a smaller electrode gap in the A11‐VAR. For ion chambers with identical electrode gap (A11‐TPP and A30), higher electric field strengths were found to yield better CCE at higher DPP. A PW dependence was observed at low electric field strengths (500 V/mm) for DPP values ranging from 1 to 5 Gy at PWs ranging from 0.5 to 4 µs, but at electric field strengths of 1000 V/mm and higher, these effects become negligible.ConclusionThis study confirmed that the CCE of ion chambers depends strongly on the electrode spacing and the electric field strength, and also on the DPP and the PW of the UHDR beam. A significant finding of this study is that although chamber performance does depend on PW, the effect on the CCE becomes negligible with reduced electrode spacing and increased electric field. A CCE of ≥95% was achieved for DPPs of up to 5 Gy with no observable dependence on PW using the A30 chamber, while still achieving an acceptable performance in conventional dose rate beams, opening up the possibility for this type of chamber to be used as a reference class chamber for calibration purposes of electron FLASH beamlines.
