The place of celecoxib in the pain management of joint and spine diseases
Authors: Barna O. M.
Published: December 2024

Non-steroidal anti-inflammatory drugs play an important role in the symptomatic and pathogenetic treatment of joint and spinal pain in osteoarthritis, rheumatoid arthritis, and ankylosing spondylitis. However, there is a certain caution in the use of non-selective NSAIDs, as their use is associated with a number of side effects. NSAIDs that inhibit cyclooxygenase-2 (COX-2), or so-called highly selective NSAIDs or coxibs, have proven to be effective analgesics with a high safety profile. A number of clinical trials have shown that celecoxib, as one of the COX-2 NSAIDs, does not cause an increased risk of gastrointestinal bleeding, gastric or duodenal ulcers, increased blood pressure, bronchospasm, and other complications. Celecoxib can be prescribed for a long time and at the same time be safe and physically effective in terms of analgesic effect.
The impact of the myocardial infarction of the right ventricle on the clinical course of acute period and long-term prognosis of patients with the Q-myocardial infarction of the left ventricular posterior wall
Authors: Lozova T. A.
Published: December 2024

The aim. To evaluate the effect of myocardial infarction (MI) of the right ventricle (RV) on the clinical course of acute period and long-term prognosis of patients with the Q-MI of the left ventricular posterior wall (PWLV).
Materials and methods. The study involved 256 patients with Q-MI PWLV aged 64,21±0,6 years. Patients were divided into 2 groups: the 1st group – 155 patients with MI of the RV on the background of Q-MI PWLV, the 2nd group – 101 patients with Q-MI PWLV. Follow-up was 30.6±4.5 months. Study endpoints were: unstable angina (UA), recurrent MI (Re-MI), stroke, cardiovascular (CV) death and HF-hospitalizations.
Results. The acute period RV MI associated with the significantly higher frequency of the ventricular tachycardia (p=0.0257), ventricular fibrillation (p=0.0249), complete AV block (p=0.0011), cardiogenic shock (p=0,0096), the early post-infarction angina (p=0.0306) and severe manifestations of HF.
As a result of 30.6 month follow-up endpoint reached 65 (41.9 %) patients after RV MI, and 29 (28.7 %) patients in the 2nd group (Cox’s F-Test: p=0,01043). The frequency of the CV-death (p=0.1258), Re-MI (p=0.838) and stroke (p=0.5108) were not significantly different between the group at the end of observation, however, in patients after RV MI the frequency of the UA (p=0.0452) and HF-hospitalization (p=0.0387) were significantly higher.
Conclusion. The presence of the RV MI in patients with Q-MI PWLV associated with greater frequency of life-threatening complications of the acute period and a significant increase of the CV-events during the 30.6 months of follow-up.

The characterization of young planets (<300 Myr) is pivotal for understanding planet formation and evolution. We present the 3–5 μm transmission spectrum of the 17 Myr, Jupiter-size (R ∼10R
⊕) planet, HIP 67522b, observed with JWST NIRSpec/G395H. To check for spot contamination, we obtain a simultaneous g-band transit with the Southern Astrophysical Research Telescope. The spectrum exhibits absorption features 30%–50% deeper than the overall depth, far larger than expected from an equivalent mature planet, and suggests that HIP 67522b’s mass is <20 M
⊕ irrespective of cloud cover and stellar contamination. A Bayesian retrieval analysis returns a mass constraint of 13.8 ± 1.0 M
⊕. This challenges the previous classification of HIP 67522b as a hot Jupiter and instead, positions it as a precursor to the more common sub-Neptunes. With a density of <0.10 g cm−3, HIP 67522 b is one of the lowest-density planets known. We find strong absorption from H2O and CO2 (≥7σ), a modest detection of CO (3.5σ), and weak detections of H2S and SO2 (≃2σ). Comparisons with radiative-convective equilibrium models suggest supersolar atmospheric metallicities and solar-to-subsolar C/O ratios, with photochemistry further constraining the inferred atmospheric metallicity to 3 × 10 solar due to the amplitude of the SO2 feature. These results point to the formation of HIP 67522b beyond the water snowline, where its envelope was polluted by icy pebbles and planetesimals. The planet is likely experiencing substantial mass loss (0.01–0.03 M
⊕ Myr−1), sufficient for envelope destruction within a gigayear. This highlights the dramatic evolution occurring within the first 100 Myr of its existence.
Unfolding X-Ray Spectral Data: Conditions and Applications
Authors: Gunderson Sean J. , Huenemoerder David P.
Published: December 2024

We present conditions for which X-ray spectra can be “unfolded” to present an accurate representation of the true source spectra. The method we use to unfold the data is implemented in the Interactive Spectral Interpretation Software and distinguishes itself as being model-independent. We find that this method of unfolding makes accurate representations of the true source spectra: (1) The detector is high-resolution, and (2) The spectrum is not steeply sloped. These criteria are not simple conditions that give concrete determinations; each detector and spectrum must be judged individually. We find that both grating and imaging detectors can be unfolded with minimal distortions as compared to both continuum and local spectral features, the latter CCD detectors being much more energy dependent. We also provide example use cases for unfolding in the context of current generation X-ray observatories and important caveats.
Exploring Field-evolution and Dynamical-capture Coalescing Binary Black Holes in GWTC-3

Published: December 2024

We investigate formation channels for merging binary black holes (BBHs) in GWTC-3, with a dedicated semiparametric population model. The model first describes or excludes a high-spin (with magnitudes of ∼0.7) and high-mass (ranging in ∼20–80M
⊙) subpopulation, which was identified by previous works and can be interpreted as hierarchical mergers. We find that the rest of BBH population can be categorized into two subpopulations with different mass and mass-ratio distributions, as indicated by a Bayes factor of

ln
B
=
1.8

. One subpopulation, characterized by nearly aligned spins and consistent with isolated field formation, likely dominates the 10-solar-mass peak in the primary-mass function. The other subpopulation, with isotropic spins and consistent with the dynamical channels, shows a stronger preference for symmetric pairing, and mainly contributes to the 35-solar-mass peak in the primary-mass function. Note that the Bayes factor is not high enough with the currently available data, so that the case of a single population is still acceptable. Additionally, we compare the mass distributions between merging BBHs and black holes (BHs) in high-mass X-ray binaries (HMXBs). We find that the primary mass of the aligned subpopulation is slightly lighter than those of the HMXB BHs, while the isotropic subpopulation is consistent with the HMXB BHs, if the power-law index of its mass function is shifted by 2, as indicated by the dynamical formation channels. However, the spin magnitudes of both subpopulations are significantly smaller than those of the HMXB BHs.

We make an in-depth analysis of different active galactic nuclei (AGN) jet models’ signatures, inducing quiescence in galaxies with a halo mass of 1012
M
⊙. Three jet models, including cosmic-ray-dominant, hot thermal, and precessing kinetic jets, are studied at two energy flux levels each, compared to a jet-free, stellar feedback-only simulation. Each of our simulations is idealized isolated galaxy simulations with AGN jet powers that are constant in time and generated using GIZMO and with FIRE stellar feedback. We examine the distribution of Mg ii, O vi, and O viii ions, alongside gas temperature and density profiles. Low-energy ions, like Mg ii, concentrate in the interstellar medium (ISM), while higher energy ions, e.g., O viii, prevail at the AGN jet cocoon’s edge. High-energy flux jets display an isotropic ion distribution with lower overall density. High-energy thermal or cosmic-ray jets pressurize at smaller radii, significantly suppressing core density. The cosmic-ray jet provides extra pressure support, extending cool and warm gas distribution. A break in the ion-to-mass ratio slope in O vi and O viii is demonstrated in the ISM-to-circumgalactic medium (CGM) transition (between 10 and 30 kpc), growing smoothly toward the CGM at greater distances.
Comparison of the Chemical Compositions between the Bright and Faint Red Clumps for the Metal-poor and Metal-rich Populations in the Milky Way Bulge
Authors: Hong Seungsoo , Lim Dongwook , Lee Young-Wook
Published: December 2024

We examined the double red clump (RC) observed in the Galactic bulge, interpreted as a difference in distance (“X-shaped bulge scenario”) or in chemical composition (“multiple population scenario”). To verify chemical differences between the RC groups, we performed low-resolution spectroscopy for RC and red giant branch (RGB) stars using Gemini-South/GMOS in three fields of the bulge and collected diverse data from the literature. We divided our sample stars not only into bright RC (bRC) and faint RC (fRC) groups, but also into bluer ([Fe/H] < −0.1) and redder ([Fe/H] > −0.1) groups following recent u-band photometric studies. For the metal-poor stars, no statistically significant difference in the CN index was detected between the bright and faint RC groups for all observed fields. However, we found, from crossmatching with high-resolution spectroscopic data, a sign of Na enhancement in the “metal-poor and bright” RC group compared to the “metal-poor and faint” group at (l, b) = (−1°, −8.°5). When the contributions of the RGB stars on the RC regimes are taken into account, the Na abundance difference between genuine RCs would correspond to Δ[Na/Fe] ≃ 0.23 dex, similar to a globular cluster (GC) with multiple populations. In contrast, the metal-rich stars do not show chemical differences between the bright and faint RC groups. This implies that the double RC observed in the metal-poor component of the bulge might be linked to the multiple populations originating from GC-like subsystems, whereas that of the metal-rich component would have been produced by the X-shaped structure. Our results support previous studies suggesting the composite nature of the Milky Way bulge.
Simulations of the Collision between a Debris Stream and an Outer Dusty Torus: A Possible Channel for Forming a Fast-rise and Long-delay Radio Outburst in Tidal Disruption Events

Published: December 2024

A geometrically thick dusty torus structure is believed to exist in the nuclear regions of galaxies (especially in active galactic nuclei). The debris stream from a tidal disruption event (TDE) will possibly collide with the dusty torus and produce a transient flare. We perform three-dimensional hydrodynamic simulations to model the dynamical evolution of the interaction between unbound debris and a dusty torus. During the continuous interaction, shocked material will be spilled out from the interaction region and form an outflow. We calculate the temporal evolution of synchrotron emission by assuming that the shock accelerates a fraction of electrons in the outflow into a nonthermal distribution. We find that radio emission from the debris–torus collision generates a steep-rise and slow-decline radio light curve due to the sharp edge and dense gas of the dusty torus, where the radio outburst is delayed relative to the main optical/X-ray outburst by several years or even several tens of years. We apply our model to a TDE that happened in a narrow-line Seyfert I galaxy (PS16dtm), where both the radio spectrum and the light curve can be roughly reproduced. Future high-sensitivity, wide-field-of-view radio surveys have the opportunity to detect more such radio flares.

Published: December 2024

Chinese Space Station Telescope (CSST) has the capability to conduct a slitless spectroscopic survey simultaneously with a photometric survey. The spectroscopic survey will measure slitless spectra, potentially providing more accurate estimations of galaxy properties, particularly redshifts, compared to using broadband photometry. CSST relies on these accurate redshifts to use baryon acoustic oscillations (BAOs) and other probes to constrain the cosmological parameters. However, due to the low resolution and signal-to-noise ratio of slitless spectra, measurement of redshifts is significantly challenging. In this study, we employ a Bayesian neural network (BNN) to assess the accuracy of redshift estimations from slitless spectra anticipated to be observed by CSST. The simulation of slitless spectra is based on real observational data from the early data release of the Dark Energy Spectroscopic Instrument (DESI-EDR) and the 16th data release of the Baryon Oscillation Spectroscopic Survey (BOSS-DR16), combined with the 9th data release of the DESI Legacy Survey (DESI LS DR9). The BNN is constructed employing a transfer learning technique, by appending two Bayesian layers after a convolutional neural network, leveraging the features learned from the slitless spectra and corresponding redshifts. Our network can provide redshift estimates along with corresponding uncertainties, achieving an accuracy of σ

The spectra allowed us to identify 11 galaxies with quiescent spectra. In all, 3 galaxies with quiescent spectra are possibly still star forming according to spectral energy distribution fitting, indicating a possible leftover or dust-obscured star formation. We estimate a quiescent fraction of ∼50% for M

⊙. About half of the quiescent galaxies possibly host an active galactic nucleus (AGN), hinting at AGN’s key role in quenching galaxies in the protocluster environment. These quiescent galaxies have relatively more compact and concentrated light profiles than the star-forming members, but they are not yet as bulge dominated as local ellipticals. These results are consistent with previous studies that indicate the Spiderweb protocluster is in the maturing stage, with a red sequence that has begun forming.

Published: December 2024

AIM: Firstly, this study aimed to compare between different clinical findings commonly measured in physical therapy among healthy individuals and those with patellofemoral pain syndrome (PFPS). Secondly, this study aimed to investigate the correlation between several clinical findings in individuals with PFPS including Craig’s test, quadriceps (Q) Angle and Kujula test and the findings of computed tomography (CT).
METHODS: Twenty-nine healthy individuals and thirty individuals diagnosed with PFPS were enrolled in the study after signing a consent form. The examiner took the medical history and fills the data collection sheet for each participant and they were examined for the following measures Craig’s test, Q-Angle and Kujula test. The participants in the experimental (PFPS) group were further investigated using CT.
RESULTS: There was no significant difference between patients and controls in the mean age, weight, height and BMI. Significant decrease of Kujula in patient group compared to control group (p=0.0001) and there was significant increase of Q angle and Criage test in patients than controls (P= 0.026 and P= 0.017 respectively). There was significant positive correlation between Kujula and congruence angle and patellar weber (P < 0.01). Moreover, significant positive correlation was observed between Craig’s test and patellar tendon ratio. While, negative correlation was found between Q angle and patellar tendon ratio.
CONCLUSIONS: Kujala Score, Q angle and Criage test were proved to be valid and sensitive to clinical changes in PFPS and have moderate to good concordance with CT parameters

Prescribed-time trajectory tracking control for a class of nonlinear system

Published: December 2024

Previous works have analyzed finite/fixed-time tracking control for nonlinear systems. In these works, achieving the accurate time convergence of errors must be under the premise of known initial values and careful design of control parameters. Then, how to break through the constraints of initial values and design parameters for this issue is an unsolved problem. Motivated by this, we successfully studied prescribed-time tracking control for single-input single-output nonlinear systems with uncertainties. Specifically, we designed a state feedback controller on $ [0, {T}_{p}) $, based on the backstepping method, to make the tracking error (TE) tend to zero at $ {T}_{p} $, in which $ {T}_{p} $ is the arbitrarily selected prescribed-time. Furthermore, on $ [{T}_{p}, \mathrm{\infty }), $ another controller, similarly to that on $ [0, {T}_{p}) $, was designed to keep TE within a precision after $ {T}_{p} $, while TE may not stay at zero. Therefore, on $ [{T}_{p}, \mathrm{\infty }) $, another new controller, based on sliding mode control, was built to ensure that TE stays at zero after $ {T}_{p}. $
La fabrique de la mémoire sur l’estran : esquisse d’analyse symbolique d’un conflit opposant acteurs de la biodiversité et de la pêche à pied professionnelle
Authors: Amand Rudy
Published: December 2024

Cet article revient sur une recherche originale menée auprès des acteurs du Golfe du Laugier qui visait à identifier les composantes de la mémoire collective susceptibles de devenir des ressources mobilisables dans le cadre de l’adaptation des communautés locales au changement climatique. En prenant appui sur un conflit latent opposant les pêcheurs à pied professionnels et les acteurs de la protection de la biodiversité autour de l’accès à un gisement de coques situé dans la Réserve naturelle du Golfe, ce texte prend acte de la disparition d’espaces facilitant le dialogue entre savoirs d’usage et savoirs experts au moment de réfléchir à la gestion de l’écosystème. Cette situation impose une réflexion quant à la manière dont chacun de ces groupes parvient ou non à s’approprier l’estran sur le plan symbolique ainsi que sur le rôle joué par la mémoire dans la fabrique d’un lieu anthropologique qui leur soit propre. Il apparaît alors que les ressources mémorielles mobilisées par les acteurs de la biodiversité induisent une légitimation plus aisée de leur action auprès des acteurs institutionnels quand celles des pêcheurs à pied de coques participent à leur invisibilisation voire à leur exclusion. Pourtant, l’agilité avec laquelle la mémoire collective de ce groupe professionnel se reconfigure pour s’adapter au contexte de l’ensablement du Golfe témoigne de l’intérêt de laisser une place aux représentations d’un lieu marqué par le mouvement et la transformation au moment où les sociétés doivent composer avec les conséquences incertaines du changement climatique.
Les espaces de l’électorat écologiste
Authors: Combettes Clément
Published: December 2024

Les différentes approches visant à saisir la géographie du vote écologiste Français soulignent généralement son aspect urbain. En effet, la composition sociale des grandes métropoles et la sociologie des votants écologistes semblent entretenir des liens étroits : haut degré de capital culturel, jeunesse, importance des travailleurs du secteur public, etc. Pourtant, les analyses contemporaines du comportement électoral insistent sur l’importance de configurations sociales localisées, formant ainsi des dispositifs informels de mobilisation, permettant notamment la diffusion de discours localement légitimes. Ces notions permettent de saisir le vote au-delà du seul déterminisme des « variables lourdes ». L’article présenté ici vise à identifier différents types de configurations socio-spatiales favorables aux écologistes par l’étude des trois dernières élections européennes et grâce à une méthodologie quantitative. Pour ce faire, nous tenterons d’identifier des espaces où les résultats écologistes sont remarquables, puis de saisir les configurations socio-spatiales de ces espaces afin de comprendre quelle influence ces configurations a-t-elle pu avoir sur le vote écologiste.

Technology will play an important role in the circular economy today and in the future as businesses strive to evolve capabilities to achieve sustainable goals. Innovations in supply chain operations are also picking up pace, and with the invention of cloud-based computing, supply chain integration is now digitally possible. However, the question remains whether the same digital supply chain capabilities would also be beneficial in improving or impacting the sustainable performance of business enterprises to create an ideal circular economy. Another important feature of cloud technology is software-as-a-service, providing supply chain software for users across the globe to provide organizations with capabilities like integration and resilience. Based on the cloud computing innovations in discussion and sustainability in the context of circular economy, the chapter brings forward an empirical study to understand the role of cloud technology, more importantly, SaaS, in building resilience and achieving sustainability in supply chains.

Published: December 2024

Electrospun piezoelectric nanofibrous membrane developed from Polyvinylidene fluoride (PVDF) embedded with thermoplastic polyurethane (TPU) composites found to have superior stretchability and piezoactivity. The piezoresponse behavior of different in-situ bended PVDF/TPU, up to 15wt.% of TPU, is examined using various blending ratios of PVDF and TPU. It has been shown that adding TPU with PVDF at certain specific concentration increased the nanofiber's piezo-efficiency.The generated nanomembranes are annealead at different temperatures up to 100°C. An extensive analysis of the effects of annealing is conducted on these nanomats, and it is thought to be a crucial post-treatment method for improving the piezoresponse of the manufactured nanomats. Nanofibers annealed at 100°C showed best effective response compared to all other samples and this revealed the effectiveness of annealing treatment in the enhancement of piezoactivity. The best effective composition of PVDF with 15 wt% TPU after an annealing treatment of 100°C generated a maximum voltage of 3.2 V under the effect of an applied force of 3 N, where unannealed sample of the same PVDF-TPU composition generated only a voltage of 2.2 V. This annealed piezo nanogenerator (PNG), can be considered an optimum option for electromechanical energy harvesting applications that require flexibility and self-power.

This study analyzes the thermomechanical behavior of SiC/Si/TiSi2 cermets manufactured from Peruvian wood waste of the Capirona and Capinuri species. A sustainable manufacturing process was used that uses sawdust as a precursor. The mechanical properties under compression and the elastic modulus of the cermets were characterized from room temperature to 1400°C. At room temperature, the values achieved exceed 500 MPa in both cermets, with the Capinuri precursor being slightly higher in maximum compressive strength with 691 MPa, but in elastic modulus, the Capirona cermet has a rigidity of 159 GPa. At 500°C, the cermets showed a small reduction in their mechanical performance. At 1100°C, a decrease in strength was observed to 248 MPa for Capinuri and 292 MPa for Capirona and in Young's modulus to 85.18 GPa and 91.92 GPa respectively. At 1400°C, both cermets suffered a significant deterioration of their mechanical properties due to a presumed chemical degradation of the individual components. The results demonstrate the feasibility of using wood waste as precursors for the sustainable manufacturing of advanced composite materials, however, optimization of manufacturing parameters and processes should be considered to improve the performance and stability of this material.
MicroRNAs as biomarkers for the diagnosis and prognosis of human cancer
Authors: Asslaber Daniela , Piñón  Hofbauer Josefina , Greil Richard , Egle Alexander
Published: December 2024

miRNAs are small-noncoding RNA molecules that regulate gene expression on a posttranscriptional level. A number of oncogenes and tumor suppressors were found to be targets of miRNAs and global miRNA expression signatures were able to distinguish between cancerous and non-cancerous tissues. Therefore it was not surprising that some miRNAs could be linked to the pathogenesis of cancer. In this review we provide an overview of the use of microRNAs as diagnostic and prognostic tools in cancer and focus on the use of miRNA expression as biomarker for disease activity.
Therapeutic implications of microRNAs in human cancer
Authors: Rossbach Michael
Published: December 2024

MicroRNAs (miRNAs) are a class of highly evolutionarily conserved non-coding RNAs (ncRNAs) that modulate gene expression. Several studies have shown that the expression of miRNAs is deregulated in human malignancies. For ncRNAs and miRNAs, such gene-profiling studies in tumorigenic tissues have identified significant signatures that are of both diagnostic and prognostic value. Addressing the functions of ncRNAs not only give insights into the molecular mechanisms that underlie complex genetic processes, but may also elucidate novel mechanisms that contribute to early stages of tumor development, progression and metastasis. MiRNA-based novel approaches target the ncRNAome, including, for instance, miRNA expression levels and improved designs of miRNA-mimics or more precise target-predictions, prevent off-target effects of novel drugs and make miRNAs become a highly efficient class of therapeutics. For miRNA-based therapeutic studies two direct strategies are currently under investigation, viz. (i) the overexpression of given miRNAs to inhibit the expression of protein-coding genes or (ii) the inhibition of target miRNAs with antisense constructs like antagomiRs. Indirect strategies include the use of novel drugs that modulate miRNA expression levels by directly targeting their processing or transcription. Further, miRNA-based biomarkers have a significant impact on the development of both therapeutic and diagnostic agents, a concept known as theranostics and are highly relevant for drug development and personalized medicine.
Non-coding RNAs and cancer: microRNAs and beyond
Authors: Raia Rachel Marie , Calin George Adrian
Published: December 2024

Non-coding RNAs were previously thought to have little importance because they are not directly translated into a protein like their coding counterparts. However, it was recently found that non-coding RNAs do in fact have a much bigger role than previously thought. They are involved in cancer predisposition, development and progression. MicroRNAs, very short non-coding RNAs, are abnormally expressed in cancer and some harbor mutations that affect expression levels. MicroRNA alterations have been observed in all forms of cancer that have been researched to the current date. MicroRNAs are also located in cancer- associated genomic regions, which have been previously shown to affect gene expression leading to the activation or inhibition of cancer growth. Single-nucleotide polymorphisms within microRNAs can predispose someone to cancer. MicroRNAs have been shown to target both tumor suppressors, inhibiting cancer development, as well as oncogenes, stimulating cancer development. Some microRNAs can switch between these two functions and behave as a tumor suppressor at one time and an oncogene at another time. MicroRNAs can be used for diagnostic purposes as well as prognostic evaluations. Outside of microRNAs, ultraconserved genes, another group of non-coding RNAs, also express differently in cancer patients. Large intervening non-coding RNAs, specifically one termed HOTAIR, have been quantified in very high levels in cancer cells and have been implicated in metastasis. Further research into noncoding RNAs may allow for the development of therapies that will target non-coding RNAs creating better treatment options for cancer patients, improving their prognosis. This review discusses the most current discoveries about non-coding RNAs, revealing their associations with cancer.
A new entropy model for RNA: part III. Is the folding free energy landscape of RNA funnel shaped?
Authors: Dawson Wayne , Takai Toshikuni , Ito Nobuharu , Shimizu Kentaro , Kawai Gota
Published: December 2024

The concept of a free energy (FE) landscape, in which the conformations of a polymer progressively take on the structure of the native state while spiraling down a FE surface that resembles the shape of a funnel, has long been viewed as the reason why a complex protein structure forms so rapidly compared to the number of conformations available to it. On the other hand, this landscape picture is less clear with RNA due to the multiplicity of conformations and the uncertainties in the current thermodynamics. It is therefore sometimes proposed that within the ensemble of suboptimal states of the RNA molecule, the vast majority of those states all closely resemble the native state and therefore simply overwhelm the few states that represent the global minimum FE. However, calculations of the free energy of observed structures often suggest that the most frequently observed cluster of structures are far from the minimum FE, particularly in the case of long sequences. If so, then such a FE surface is unlikely to be funnel shaped. We have been developing a version of vsfold that can evaluate the suboptimal structures of the FE surface (through a modified version called vs_subopt). Here we show that the ensemble of suboptimal structures for a number of known RNA structures can actually be both close to the minimum FE and also be the dominant observed structure when a proper Kuhn length is selected. Two state aptamers known as riboswitches can show neighboring FE states in the suboptimal structures that match the observed structures and their relative difference in FE is well within the range of the binding free energy of the metabolite. For the riboswitches and other short RNA sequences (less than 250 nt), the flow of the suboptimal structures (including pseudoknots) tended to resemble a rock rolling down a hill along the reaction coordinate axis. An important insight yielded by the cross-linking entropy (CLE) model is that the global entropy limits the size of domains. Hence, based on the CLE model, Levinthal’s paradox is overcome by the funnel shape in the FE, by a reduction in the number of degrees of freedom due to Kuhn length, and by limits on the size of the domains that can form. These concepts are also applicable to calculating transition rates between different suboptimal structures.

Her influence: The constructive roles of women in the lives of Moses and Boaz
Authors: Diko Mlamli
Published: December 2024

This article critiques the constructive roles of women in the lives of Moses and Boaz applying feminist biblical criticism as a theory. By critiquing the significant yet often downplayed contributions of women such as Jochebed, Miriam, Ruth and Naomi, the aim is to provide a more inclusive and multifaceted understanding of their roles in different biblical texts. In the process, feminist biblical criticism, as a theory, unmasks the pervasive influence of sexism in both the biblical texts and their interpretive traditions, contesting traditional readings that subjugate women’s voices and agency. Ultimately, this article makes two notable findings. Firstly, the central role of Jochebed and Miriam in ensuring Moses’ survival and rise to leadership underscores how their actions were fundamental to the unfolding of Israel’s history. Secondly, the proactive agency of Ruth and Naomi demonstrated through their strategic decisions and mutual support, facilitated social and familial redemption and thereby transformed Boaz’s life and legacy. These notable findings underline the indispensable contributions of women in the two biblical figures and call for a (re)consideration of their roles in biblical history and contemporary contexts. Inevitably, I conclude that by reclaiming the voices and experiences of women, this article advocates for a more unprejudiced (re)interpretation of sacred canon, promoting gender justice and inclusivity in contemporary religious and cultural practices.Intradisciplinary and/or interdisciplinary implications: Examining the constructive roles of women challenges male-orientated interpretations in theology and intersects with literary, historical, sociological, gender and cultural discourses, advancing inclusive and non-partisan understandings of biblical texts.
Data-based regression models for predicting remifentanil pharmacokinetics
Authors: Shenoy Prathvi , Rao Mahadev , Chokkadi Shreesha , Bhatnagar Sushma , Salins Naveen
Published: December 2024

Background and Aims:

Remifentanil is a powerful synthetic opioid drug with a short initiation and period of action, making it an ultra-short-acting opioid. It is delivered as an intravenous infusion during surgical procedures for pain management. However, deciding on a suitable dosage depends on various aspects specific to each individual.

Methods:

Conventional pharmacokinetic and pharmacodynamic (PK-PD) models mainly rely on manually choosing the parameters. Target-controlled drug delivery systems need precise predictions of the drug’s analgesic effects. This work investigates various supervised machine learning (ML) methods to analyse the pharmacokinetic characteristics of remifentanil, imitating the measured data. From the Kaggle database, features such as age, gender, infusion rate, body surface area, and lean body mass are extracted to determine the drug concentration at a specific instant of time.

Results:

The characteristics show that the prediction algorithms perform better over traditional PK-PD models with greater accuracy and minimum mean squared error (MSE). By optimising the hyperparameters with Bayesian methods, the performance of these models is significantly improved, attaining the minimum MSE value.

Conclusion:

Applying ML algorithms in drug delivery can significantly reduce resource costs and the time and effort essential for laboratory experiments in the pharmaceutical industry.
