Abstract
We report the first experimental detection of a reflected Alfvén wave from an Alfvén-speed gradient under conditions similar to those in coronal holes. The experiments were conducted in the Large Plasma Device at the University of California, Los Angeles. We present the experimentally measured dependence of the coefficient of reflection versus the wave inhomogeneity parameter, i.e., the ratio of the wavelength of the incident wave to the length scale of the gradient. Two-fluid simulations using the Gkeyll code qualitatively agree with and support the experimental findings. Our experimental results support models of wave heating that rely on wave reflection at low heights from a smooth Alfvén-speed gradient to drive turbulence.

Abstract
We investigate the stellar and nebular properties of nine H ii regions in the spiral galaxy M101 with far-ultraviolet (FUV; ∼900–2000 Å) and optical (∼3200–10,000 Å) spectra. We detect significant C iii] λλ1907,1909 nebular emission in seven regions, but O iii] λ1666 only in the lowest-metallicity region. We produce new analytic functions of the carbon ionization correction factors as a function of metallicity in order to perform a preliminary C/O abundance analysis. The FUV spectra also contain numerous stellar emission and P-Cygni features that we fit with luminosity-weighted combinations of single-burst Starburst99 and BPASS models. We find that the best-fit Starburst99 models closely match the observed very-high-ionization P-Cygni features, requiring very hot, young (≲3 Myr), metal-enriched massive stars. The youngest stellar populations are strongly correlated with broad He ii emission, nitrogen Wolf–Rayet (WR) FUV and optical spectral features, and enhanced N/O gas abundances. Thus, the short-lived WR phase may be driving excess emission in several N P-Cygni wind features (λ955, λ991, λ1720) that bias the stellar continuum fits to higher metallicities relative to the gas-phase metallicities. Accurate characterization of these H ii regions requires additional inclusion of WR stars in the stellar population synthesis models. Our FUV spectra demonstrate that the ∼900–1200 Å FUV can provide a strong test bed for future WR atmosphere and evolution models.
Interplanetary Type IV Solar Radio Bursts: A Comprehensive Catalog and Statistical Results
Authors: Mohan Atul , Gopalswamy Nat , Kumari Anshu , Akiyama Sachiko , G Sindhuja 
Published: August 2024

Abstract
Decameter hectometric (DH; 1–14 MHz) type IV radio bursts are produced by flare-accelerated electrons trapped in postflare loops or the moving magnetic structures associated with the coronal mass ejections (CMEs). From a space weather perspective, it is important to systematically compile these bursts, explore their spectrotemporal characteristics, and study the associated CMEs. We present a comprehensive catalog of DH type IV bursts observed by the Radio and Plasma Wave Investigation instruments on board the Wind and Solar TErrestrial RElations Observatory spacecraft covering the period of white-light CME observations by the Large Angle and Spectrometric Coronagraph on board the Solar and Heliospheric Observatory mission between 1996 November and 2023 May. The catalog has 139 bursts, of which 73% are associated with a fast (>900 km s−1) and wide (>60°) CME, with a mean CME speed of 1301 km s−1. All DH type IV bursts are white-light CME-associated, with 78% of the events associated with halo CMEs. The CME source latitudes are within ±45°. Seventy-seven events had multiple-vantage-point observations from different spacecraft, letting us explore the impact of the line of sight on the dynamic spectra. For 48 of the 77 events, there were good data from at least two spacecraft. We find that, unless occulted by nearby plasma structures, a type IV burst is best viewed when observed within a ±60° line of sight. Also, bursts with a duration above 120 minutes have source longitudes within ±60°. Our inferences confirm the inherent directivity in the type IV emission. Additionally, the catalog forms a Sun-as-a-star DH type IV burst database.

Abstract
This work is part of VESTALE, a project initiated within the Legacy Survey of Space and Time (LSST) Cadence Strategy Optimization Process. Its goal is to explore the potential of Rubin-LSST observations aimed at the Galactic bulge (henceforth just “Bulge”) for studying RR Lyrae (RRL) stars. Observation and analysis of RRL stars in the Bulge are crucial for tracing the old population of the central part of our Galaxy and reconstructing its formation. Based on observations conducted with CTIO/DECam by Saha et al. toward Baade’s window, our simulations demonstrate that early Rubin-LSST observations will enable the recovery of RRL light curves (LCs) at Galactic center distances with sufficient precision. This will allow us to utilize theoretical relations from Marconi et al. to determine their distances and/or metallicity, following the REDIME algorithm introduced in Bono et al. We show how reddening and crowding affect our simulations and highlight the importance of considering these effects when deriving pulsation parameters (luminosity amplitudes, mean magnitudes) based on the LCs, especially if the goal is to explore the opposite side of the Bulge through the observation of its RRL. The simulations discussed in this investigation were conducted to support the Survey Cadence Optimization Committee’s decision to observe this important sky region since it has only recently been decided to include part of the Bulge as a target within the LSST main survey.
The Solar Magnetic Hump, Heliopause, and the Very Local Interstellar Medium
Authors: Burlaga L. F. , Park J. , Berdichevsky D. B. , Jian L. K. , Szabo A. 
Published: August 2024

Abstract
The magnetic hump was observed from 2020.4 to ∼2022 by Burlaga et al. who offered the hypothesis that it originated at the Sun during the declining phase of the solar cycle. Voyager 1 observed intermittency of 1 hr increments of the magnetic field from 2013 through 2019, as well as in the magnetic hump that began at the jump pf2 at 2020.4 and ended at ∼2022. Throughout this interval, the intermittency in the components of

and the magnitude B was described by the Tsallis distribution (q-Gaussian distribution). The q-Gaussian distributions have been observed throughout the solar wind and heliosheath. However, there was little or no intermittency in the 1 hr increments of the magnetic field observed by Voyager 1 from ∼2022.0 through day 270, 2023. During this interval Voyager 1 observed intermittency with a Gaussian distribution, which is associated with Boltzmann–Gibbs statistics. The boundary between these two regions, at ∼2022.0, coincides with the heliopause predicted by Fisk & Gloeckler. Alternatively, the Voyager 1 observations might be a solar cycle effect.

at z = 2, both in real and redshift space, calibrated upon two fixed-and-paired cosmological hydrodynamic simulations. To measure the BAO, we stack the 3D power spectra of the 1000 different realizations, compute the average, and use a model accounting for a proper smooth-peak component decomposition of the power spectrum, to fit it via an efficient Markov Chain Monte Carlo scheme estimating the covariance matrices directly from the simulations. We report the BAO shift parameters to be

Multicolor Photometry of the Be/X-Ray Pulsar IGR J06074+2205
Authors: Schmidtke Paul , Hunter Tim , Cowley Anne 
Published: August 2024

Abstract

B, V, and R observations of the Be/X-ray pulsar IGR J06074+2205 were taken in 2023–2024 covering times of expected X-ray outbursts. However, no coinciding optical outbursts were found. The overall optical brightness of the system faded in all 3 filters, with the least decline being in B and the greatest in R. This suggests that a cool disk was contributing less light to the system.

Authors: Golmohammadi Maryam , Motahari Rad Hanieh , Soleimanpour-Lichaei Samereh , Olya Mohammad Emad , Soleimanpour-Lichaei Hamid Reza 
Published: August 2024

Abstract

Background:
Piwi-like RNA-mediated gene silencing 2 (PIWIL2) is a member of AGO/PIWI gene family, which is enriched in cancer stem cells (CSCs). The purpose of this research was to investigate the overexpression of PIWIL2 and its role in the induction of EMT and CSC properties in MCF7 breast cancer cell line.

Materials and Methods:
MCF7 cells were transfected with the human gene PIWIL2 (Hili) under the control of CMV promoter utilizing the neon electroporation method. Subsequently, the selection was conducted using G418, and doubling time was calculated in the transformed and control cells. RT and real-time PCR were also performed to analyze the expression of epithelial and mesenchymal genes and those related to CSCs.

Results:
According to the observations from this study, transfecting MCF7 cells with PIWIL2 triggered the conversion of epithelial cells to mesenchymal cells and induced the genes specific for breast CSCs, which was coincident with 9-h reduction in the doubling time of the transfected cells. Furthermore, the molecular analyses revealed a significant reduction in the expression of epithelial markers, while a significant increase was detected in the expression of mesenchymal genes and many CSC biomarkers.

Conclusion:
PIWIL2 protein acts as a master regulatory protein that is able to manipulate the transcription through specific signaling pathways, which allow the cells to gain stem cell-like properties.

Abstract

Backgroud:
Because of the important role of adhering to treatment to reduce major adverse cardiovascular events and mortality, studying the factors affecting treatment adherence (TA) is warranted. This study aimed to identify the impact of psychosomatic factors on adhering to treatment among patients with acute myocardial infarction.

Materials and Methods:
This is a cohort study as a part of the Isfahan ST-segment-elevated Myocardial Infarction Cohort Study. Psychosomatic factors such as health anxiety, illness denial, irritable mood, and demoralization were assessed among 867 patients at the first visit. The patients were followed for 2 years; TA and major adverse cardiovascular events were checked annually in survivors.

Results:
The results from binary logistic regression applied to find the association between TA and psychosomatic factors showed that the patients with health anxiety, irritable mood, and demoralization were significantly poor adherent to treatment (odds ratio [95% confidence interval]: 1.39 [1.02, 2.73], 1.51 [1.02, 2.37], and 1.66 [1.02, 2.91]), respectively. The associations remained the same when adjusted for various potential confounders.

Conclusions:
Psychosomatic factors played an essential role in adhering to treatment among patients with acute myocardial infarction. As a result, appropriate psychological interventions may help the patients adhere to their treatment better.

AbstractBackground:Early colorectal cancer (CRC) diagnosis can drastically reduce CRC-related morbidity and mortality. In this regard, increasing attention is now being directed to DNA-based tests, especially the evaluation of methylation levels, to prioritize high-risk suspected persons for colonoscopy examination. Therefore, we aimed to assess the accuracy ofMGMTgene promoter methylation levels in peripheral blood mononuclear cells (PBMCs) for distinguishing CRC patients from healthy people.Materials and Methods:For this study, a total of seventy individuals with CRC and 75 healthy individuals from Iran were included. The methylation level ofMGMTin the DNA isolated from PBMCs was evaluated using the methylation quantification endonuclease-resistant DNA technique. To assess the diagnostic capability of theMGMTpromoter methylation level, a receiver operating characteristic (ROC) curve was generated.Results:The mean promoter methylation level ofMGMTin the CRC and control groups was, respectively, 27.83 ± 22.80 vs. 12.36 ± 14.48. The average percentage of methylation of theMGMTpromoter between the CRC and control groups was significantly different (P< 0.001). Also, the MGMT promoter was more hypermethylated in female patients than in males. ROC analyses indicated that the diagnostic power of theMGMTpromoter methylation level for CRC was 0.754, with a sensitivity of 81.43% and a specificity of 75.71%, indicating a good biomarker for CRC diagnosis.Conclusion:Methylation evaluation ofMGMTin PBMCs could be utilized as a diagnostic biomarker with high accuracy for prioritizing suspected CRC patients before colonoscopy.

Published: August 2024

Introduction:The efficacy of infiltration versus inferior alveolar nerve block (IANB) injection techniques during periodontal flap surgery in the mandible is crucial for optimising patient care. This comparative study aims to evaluate the pain management, ease of administration and clinical outcomes associated with both anaesthetic methods. Infiltration anaesthesia involves localised administration, targeting specific sites, whereas IANB provides a broader anaesthetic effect by numbing the entire mandibular nerve. Understanding the advantages and limitations of each technique will enhance procedural efficiency and patient comfort. This research contributes valuable insights into best practices for periodontal surgeries.Materials and Methods:Twenty-five subjects who required periodontal flap surgery were included in the study to treat chronic periodontitis in the mandibular jaw. The surgery was performed under local infiltration of an anaesthetic agent on one side of the jaw and by an IANB on the other side. Pain perception was evaluated using the Visual Analogue Scale (VAS) score at various intervals during periodontal flap surgery. The effect of anaesthesia between the two techniques was compared and evaluated by analysis of variance using IBM Corp. IBM Statistical Package for Social Sciences (SPSS) Statistics for Windows [Version 25]. Armonk, New York, USA. IBM Corp; 2017.Results:Analysis determined the onset, duration and termination of anaesthesia induced by infiltration and the IANB technique. The onset and duration of anaesthesia by both techniques were comparable. The pain perception evaluated using the VAS score while using both anaesthesia techniques was also comparable.Conclusion:Infiltration anaesthesia can be used as an alternative to overcome the disadvantages and complications of IANB for periodontal surgery in the mandibular jaw.

Published: August 2024

Introduction:
Mandibular fractures, representing 35.54%–44.2% of facial fractures, often affect the mandibular body and subcondylar region. Effective treatment seeks optimal reduction, stable fixation and functional restoration. This study assesses a modified three-dimensional C plate’s efficacy in treating mandibular fractures, emphasising occlusal forces and the mental nerve region.

Materials and Methods:
A randomised clinical trial (2019–2024) involving 20 patients with mandibular fractures was conducted. Group A (10 patients) received the modified C titanium plate and Group B (10 patients) received conventional miniplates. The clinical parameters – pain, occlusion, mobility, bite force and neurosensory deficits – were evaluated pre- and postoperatively at various intervals. Statistical analysis was performed using the SPSS software.

Results:
Group A shows superior bite force and functional outcomes, with significant neurosensory recovery by the 10th day. Both groups had no plate fractures, screw loosening or infections. Group A also had better stability, reduced procedural time and improved post-operative comfort.

Conclusions:
The modified C miniplate provides superior stabilisation, simplifies application, reduces complications and enhances early functional recovery compared to conventional miniplates.
