Dingle’s self-resurgence formula

If a nonlinear function F(S) depends on a function S(x) that is represented by a factorially divergent asymptotic power series in a small parameter x, each late coefficient of the power series for F(S(x)) can be represented explicitly as an asymptotic series whose terms involve balanced combinations of the late and early coefficients of the series for S(x). The formula for the late terms was first described by R B Dingle but not published by him. Numerics for a variety of functions F(S) demonstrate this ‘self-resurgence’ and the accuracy of the representation.
Preparation, characterization, and bioactivity of reinforced monetite with chitosan-gelatin electrospun composite scaffold for bone tissue engineering

In this study, chitosan-gelatin-monetite (CGM)-based electrospun scaffolds have been developed that closely mimicked the microstructure and chemical composition of the extracellular matrix of natural bone. CGM-based nanofibrous composite scaffolds were prepared with the help of the electrospinning technique, post-cross-linked using ethyl(dimethylaminopropyl)carbodiimide and N-hydroxysuccinimide solution to improve their stability in an aqueous environment. The prepared chitosan/gelatin (CG) scaffold showed an average fiber diameter of 308 ± 17 nm, whereas 5 and 7 wt% monetite containing CGM5 and CGM7 scaffolds, exhibited an average fiber diameter of 287 ± 13 and 265 ± 9 nm, respectively, revealing the fine distribution of monetite particles on the fibrous surface. The distribution of monetite nanoparticles onto the CG nanofibrous surface was confirmed using x-ray diffraction, Fourier transform infrared, and EDAX. Moreover, the addition of 7 wt% monetite into the CG electrospun matrix increased their ultimate tensile strength from 7.62 ± 0.13 MPa in the CG scaffold to 14.34 ± 0.39 MPa in the CGM7 scaffold. Simulated body fluid study and staining with alizarin red S (ARS) confirmed the higher mineralization ability of monetite-containing scaffolds compared to that revealed by the CG scaffold. The monetite incorporation into the CG matrix improved its osteogenic properties, including pre-osteoblast MG-63 cell adhesion, proliferation, and differentiation, when seeded with the cells. A higher degree of cellular adhesion, spreading, and migration was observed on the monetite-incorporated CG scaffold than that on the CG scaffold. From 3-(4, 5-dimethylthiazol-2-yl-2, 5-diphenyltetrazolium bromide) MTT assay, alkaline phosphatase activity, ARS staining, and immunocytochemistry study, the cultured cells discovered a more conducive microenvironment to proliferate and subsequently differentiate into osteoblast lineage in contact with CGM7 nanofibers rather than that in CGM0 and CGM5. In-vitro results indicated that electrospun CGM-based composite scaffolds could be used as a potential candidate to repair and regenerate new bone tissues.
Forcing symmetry exchanges and flow reversals in turbulent wakes

Turbulent wakes past bluff bodies commonly present asymmetric flow states reminiscent of bifurcations in the laminar regime. Understanding the sensitivity of these states to flow forcing is crucial to the modelling and control of flow symmetry properties. In this study, the near wake of a rectangular bluff body in proximity to a wall is disturbed by the use of passive devices located between the model and the wall, upstream of the massive flow separation occurring at the blunt trailing edges. Due to the proximity to the boundary, the wake initially presents wall-normal asymmetry and a negative wall-normal pressure gradient along the base. The application of disturbances with variable size, however, sets flow symmetry along the wall-normal plane, leading to the intermittent spanwise wake reversals reported recently in the literature. A further increase in the size of perturbation suppresses wake switching, and wall-normal asymmetry is recovered, but with a positive wall-normal pressure gradient. The dynamical features of this bifurcation scenario can be retrieved using two coupled symmetry-breaking models for spanwise and wall-normal pressure gradients. This confirms the high sensitivity of the separated flow to external perturbations. More importantly, the results unify observations of the bluff-body wake topologies covered in previous investigations.
Gallic acid improves liver cirrhosis by reducing oxidative stress and fibrogenesis in the liver of rats induced by bile duct ligation

Abstract Disturbance in the production and excretion of bile acid causes cholestatic liver disease. Liver cirrhosis is a disease that occurs if cholestasis continues. This study evaluated the protective effect of gallic acid (GA) on liver damage caused by biliary cirrhosis. Rats were randomly divided into 4 groups, each with 8 subjects: 1) control, 2) BDL, 3) BDL + GA 20, and 4) BDL + GA 30. The rats were anesthetized 28 days after the BDL, followed by collecting their blood and excising their liver. Their serum was used to measure liver enzymes, and the liver was used for biochemical analysis, gene expression, and histopathological analysis. Serum levels of liver enzymes, total bilirubin, liver Malondialdehyde level (MDA), expression of inflammatory cytokines and caspase-3, necrosis of hepatocytes, bile duct proliferation, lymphocytic infiltration, and liver fibrosis showed an increase in the BDL group compared to the control group (p < 0.05). In addition, BDL decreased the activity of liver antioxidant enzymes and glutathione (GSH) levels compared to the control group (p < 0.05). The groups receiving GA indicated a decrease in liver enzymes, total bilirubin, MDA, the expression of inflammatory cytokines and caspase-3, and a reduction in liver tissue damage compared to the BDL group (p < 0.05). The level of GSH in the BDL + GA 20 group showed a significant increase compared to the BDL group (p < 0.05). Moreover, it was found that GA, with its anti-fibrotic and anti-inflammatory properties, reduces liver damage caused by biliary cirrhosis.
Challenges and opportunities in delivering oral peptides and proteins

ABSTRACT Introduction Rapid advances in bioengineering enable the use of complex proteins as therapeutic agents to treat diseases. Compared with conventional small molecule drugs, proteins have multiple advantages, including high bioactivity and specificity with low toxicity. Developing oral dosage forms with active proteins is a route to improve patient compliance and significantly reduce production costs. However, the gastrointestinal environment remains a challenge to this delivery path due to enzymatic degradation, low permeability, and weak absorption, leading to reduced delivery efficiency and poor clinical outcomes. Areas covered This review describes the barriers to oral delivery of peptides and complex proteins, current oral delivery strategies utilized and the opportunities and challenges ahead to try and circumvent these barriers. Oral protein drugs on the market and clinical trials provide insights and approaches for advancing delivery strategies. Expert opinion Although most current studies on oral protein delivery rely on in vitro and in vivo animal data, the safety and limitations of the approach in humans remain uncertain. The shortage of clinical data limits the development of new or alternative strategies. Therefore, designing appropriate oral delivery strategies remains a significant challenge and requires new ideas, innovative design strategies and novel model systems.
The interplay of financial toxicity, health care team communication, and psychosocial well-being among rural cancer patients and survivors.

BACKGROUND Financial toxicity contributes to psychosocial distress among cancer patients and survivors. Yet, contextual factors unique to rural settings affect patient experiences, and a deeper understanding is needed of the interplay between financial toxicity and health care team communication and its association with psychosocial well-being among rural oncology patients. PURPOSE We examined associations between financial toxicity and psychosocial well-being among rural cancer patients, exploring variability in these linkages by health care team communication. METHODS Using data from 273 rural cancer patients who participated in Cancer Support Community's Cancer Experience Registry, we estimated multivariable regression models predicting depression, anxiety, and social function by financial toxicity, health care team communication, and the interplay between them. RESULTS We demonstrate robust associations between financial toxicity and psychosocial outcomes among our sample of rural cancer patients and survivors. As financial toxicity increased, symptoms of depression and anxiety increased. Further, financial toxicity was linked with decreasing social function. Having health care team conversations about treatment costs and distress-related care reduced the negative impact of financial toxicity on depressive symptoms and social function, respectively, in rural cancer patients at greatest risk for financial burden. CONCLUSIONS Financial toxicity and psychosocial well-being are strongly linked, and these associations were confirmed in a rural sample. A theorized buffer to the detrimental impacts of financial toxicity-health care team communication-played a role in moderating these associations. Our findings suggest that health care providers in rural oncology settings may benefit from tools and resources to bolster communication with patients about costs, financial distress, and coordination of care.
Cyclic flow shop scheduling problem with two-machine cells

In the paper a variant of cyclic production with setups and two-machine cell is considered. One of the stages of the problem solving consists of assigning each operation to the machine on which it will be carried out. The total number of such assignments is exponential. We propose a polynomial time algorithm ﬁnding the optimal operations to machines assignment.
Assessing avian leukosis virus proviral load and lesion correlates in fowl glioma-inducing virus–infected Japanese bantam chickens

The fowl glioma-inducing virus prototype (FGVp) and its variants, which belong to avian leukosis virus subgroup A (ALV-A), induce cardiomyocyte abnormalities and gliomas in chickens. However, the molecular mechanisms underlying these myocardial changes remain unclear, and ALV-induced tumorigenesis, which is caused by proviral insertional mutagenesis, does not explain the early development of cardiac changes in infected chickens. We established a quantitative PCR (qPCR) assay to measure ALV-A proviral loads in the brains and hearts of FGV-infected Japanese bantam chickens and compared these results with morphologic lesions. Four of 22 bantams had both gliomas and cardiac lesions. Hearts with cardiac lesions had a higher proviral load (10.3 ± 2.7 proviral copies/nucleus) than those without cardiac lesions (0.4 ± 0.4), suggesting that the proviral load in hearts is correlated with the frequency of myocardial changes. Our qPCR method may be useful in the study of ALV-induced cardiomyocyte abnormalities.
Lipoprotein(a): a genetically determined risk factor for Cardiovascular disease

Abstract Lipoprotein(a) is a complex lipoprotein with unique characteristics distinguishing it from all the other apolipoprotein B-containing lipoprotein particles. Its lipid composition and the presence of a single molecule of apolipoprotein B per particle, render lipoprotein(a) similar to low-density lipoproteins. However, the presence of a unique, carbohydrate-rich protein termed apolipoprotein(a), linked by a covalent bond to apolipoprotein B imparts unique characteristics to lipoprotein(a) distinguishing it from all the other lipoproteins. Apolipoprotein(a) is highly polymorphic in size ranging in molecular weight from <300 KDa to >800 kDa. Both the size polymorphism and the concentration of lipoprotein(a) in plasma are genetically determined and unlike other lipoproteins, plasma concentration is minimally impacted by lifestyle modifications or lipid-lowering drugs. Many studies involving hundreds of thousands of individuals have provided strong evidence that elevated lipoprotein(a) is genetically determined and a causal risk factor for atherosclerotic cardiovascular disease. The concentration attained in adulthood is already present in children at around 5 years of age and therefore, those with elevated lipoprotein(a) are prematurely exposed to a high risk of cardiovascular disease. Despite the large number of guidelines and consensus statements on the management of lipoprotein(a) in atherosclerotic cardiovascular disease published in the last decade, lipoprotein(a) is still seldom measured in clinical settings. In this review, we provide an overview of the most important features that characterize lipoprotein(a), its role in cardiovascular disease, and the importance of adding the measurement of lipoprotein(a) for screening adults and youths to identify those at increased risk of atherosclerotic cardiovascular disease due to their elevated plasma concentration of lipoprotein(a).
Mise en correspondance de points 3D obtenus avec une grande "base-line"

Nous presentons dans cet article deux approches pour obtenir les points homologues entre des images prises avec une base longue d'une scene fixe. Recemment, de nombreux dispositifs d'acquisition peuvent fournir non seulement l'image mais aussi l'information 3D associee (par exemple LiDAR, camera stereo, multi-stereoscopie). Nous montrons que l'information 3D peut etre utilisee pour calculer des images qui sont invariantes pour les transformations geo- metriques (affine et perspective) entre les images stereo. Les images transformees sont ensuite appariees avec SIFT. Dans la premiere approche, pour une scene composee de surfaces planes, l'image est tranformee en une orthoimage rectifiee pour chaque plan. Avec la deuxieme approche, pour une scene de surfaces en relief, l'image est transfor- mee par une cartographie conforme (conformal mapping). Les resultats de comparaison montrent que les points ho- mologues obtenus avec nos approches sont nombreux et bien repartis dans les images.
Emerging roles of transmembrane‐type tight junction proteins in cancers

Tight junctions (TJs) are the most apical components of the cell–cell adhesion machinery in epithelial and endothelial cells and they play essential roles in homeostasis. Recent studies have revealed that aberrant expression of tight junction proteins (TJPs) is frequently observed in various type of cancers. Here we review cancer‐associated aberrant expression of TJPs with focus on transmembrane‐type TJPs including claudins, junctional adhesion molecule‐A (JAM‐A), and occludin. Some transmembrane‐type TJPs are upregulated at the early neoplastic stage and their expression persists during dedifferentiation. Aberrant expression of TJPs contributes to proliferation, invasion, and dysregulated signaling of cancer cells. In addition to an increase in their expression level, their localization is altered from a TJ‐restricted pattern to distribution throughout the whole cell membrane, making them suitable as therapeutic targets. Extracellular domains of transmembrane‐type TJPs can be approached by target drugs not only from the lumen side (apical side) but also from the extracellular matrix side (basal side), including blood vessels. Aberrantly expressed TJPs are potential useful diagnostic markers as well as therapeutic targets for cancers.
Helminths' therapeutic potential to treat intestinal barrier dysfunction

The intestinal barrier is a dynamic multi‐layered structure which can adapt to environmental changes within the intestinal lumen. It has the complex task of allowing nutrient absorption while limiting entry of harmful microbes and microbial antigens present in the intestinal lumen. Excessive entry of microbial antigens via microbial translocation due to ‘intestinal barrier dysfunction’ is hypothesised to contribute to the increasing incidence of allergic, autoimmune and metabolic diseases, a concept referred to as the ‘epithelial barrier theory’. Helminths reside in the intestinal tract are in intimate contact with the mucosal surfaces and induce a range of local immunological changes which affect the layers of the intestinal barrier. Helminths are proposed to prevent, or even treat, many of the diseases implicated in the epithelial barrier theory. This review will focus on the effect of helminths on intestinal barrier function and explore whether this could explain the proposed health benefits delivered by helminths.
Dynamic phase transitions in a van der Waals gas

is of mixed hyperbolic and elliptic type when a is a monotonically increasing function except in an interval (a,/? ) (see Fig. 1). System (1.1) has been used to describe dynamic changes of phase in a van der Waals gas [ 10] and to model elastic deformations in a rod under tension [2], Mathematically, changes of phase for Eq. (1.1) are associated with jump discontinuities (shocks) in weak solutions (u,v) of system (1.1), in which u jumps across the interval (a, /? ). There is a continuing problem of how to distinguish the phase jumps that are physically relevant. Mathematically, one would like to impose an entropy admissibility condition on all jump discontinuities that selects the physically relevant shocks, including the correct phase jumps, while giving well-posedness of the Cauchy problem. For systems of mixed type, it is not known in general what the appropriate admissibility condition should be, even if the initial data are restricted to lie entirely in the hyperbolic regions. This is largely due to the presence of noncompressive shocks, which fail to satisfy the classical entropy conditions of the theory of conservation laws [3, 4] . In the context of (1.1), noncompressive shocks are phase jumps that are typically nearly stationary (i.e., with nearly zero shock speed). When the shock speed is exactly zero, the phase jump is referred to as the Maxwell line. A requirement of an admissibility condition is that the Maxwell line should be admissible. This paper is a continuation of the study of the viscosity-capillarity criterion for shocks, introduced by Slemrod [11], In particular, I discuss solutions of the Riemann initial value problem for (1.1). This is the Cauchy problem with piecewise constant initial data having a single jump. The main result is that for initial data near the Maxwell line, the Riemann problem has a solution consisting of two weak shock or rarefaction waves, separated by a slowly moving phase jump. All the jump discontinuities are required to satisfy the viscosity-capillarity criterion. Alternative admissibility criteria for shocks in solutions of the Riemann problem for (1.1) are discussed in [1, 5, 9],
Characterizing a Joint Reflection-Distortion OAE Profile in Humans With Endolymphatic Hydrops

Objectives: Endolymphatic hydrops (EH), a hallmark of Meniere disease, is an inner-ear disorder where the membranes bounding the scala media are distended outward due to an abnormally increased volume of endolymph. In this study, we characterize the joint-otoacoustic emission (OAE) profile, a results profile including both distortion- and reflection-class emissions from the same ear, in individuals with EH and speculate on its potential utility in clinical assessment and monitoring. Design: Subjects were 16 adults with diagnosed EH and 18 adults with normal hearing (N) matched for age. Both the cubic distortion product (DP) OAE, a distortion-type emission, and the stimulus-frequency (SF) OAE, a reflection-type emission, were measured and analyzed as a joint OAE profile. OAE level, level growth (input/output functions), and phase-gradient delays were measured at frequencies corresponding to the apical half of the human cochlea and compared between groups. Results: Normal hearers and individuals with EH shared some common OAE patterns, such as the reflection emissions being generally higher in level than distortion emissions and showing more linear growth than the more strongly compressed distortion emissions. However, significant differences were noted between the EH and N groups as well. OAE source strength (a metric based on OAE amplitude re: stimulus level) was significantly reduced, as was OAE level, at low frequencies in the EH group. These reductions were more marked for distortion than reflection emissions. Furthermore, two significant changes in the configuration of OAE input/output functions were observed in ears with EH: a steepened growth slope for reflection emissions and an elevated compression knee for distortion emissions. SFOAE phase-gradient delays at 40 dB forward-pressure level were slightly shorter in the group with EH compared with the normal group. Conclusions: The underlying pathology associated with EH impacts the generation of both emission types, reflection and distortion, as shown by significant group differences in OAE level, growth, and delay. However, hydrops impacts reflection and distortion emissions differently. Most notably, DPOAEs were more reduced by EH than were SFOAEs, suggesting that pathologies associated with the hydropic state do not act identically on the generation of nonlinear distortion at the hair bundle and intracochlear reflection emissions near the peak of the traveling wave. This differential effect underscores the value of applying a joint OAE approach to access both intracochlear generation processes concurrently.
Country of birth is associated with discrepancies in the prescription of two-drug regimens in successfully treated people with HIV in France

Objectives: We aimed to examine the association of the country of birth and the other patients’ characteristics with the prescription of two-drug regimens (2DRs) in virally suppressed people with HIV (PWH) in France. Design: Observational study conducted from the national Dat’AIDS prospectively collected database. Methods: We included all adults who were actively in care on 31 December 2020 in 26 French centers, with an HIV plasma viral load (pVL) <50 copies/ml for at least 6 months while on antiretroviral therapy (ART). Patients with chronic hepatitis B were excluded because they are not eligible to 2DRs. Univariate and multivariate logistic regressions were built to analyze relationships between patients’ characteristics and receiving a 2DR. Results: We analyzed data from 28 395 PWH: 41.7% men who have sex with men, 31.7% women and 26.5% heterosexual men; 35% born abroad. Median age was 53 years [interquartile range (IQR) 44–60]; ART duration 14 years (8–23); duration of virological suppression 87 months (42–142). 2DRs (mainly dolutegravir/rilpivirine, 53.8%, or dolutegravir/lamivudine, 41.7%) were prescribed in 16.3% of the patients and were less common in the ‘born abroad’ group (18.9% versus 11.5%). The multivariate model showed that individuals born in France were more likely to receive a 2DR [adjusted odds ratio (aOR): 1.62 [1.50–1.74]], independently of other characteristics. Older PLWH and those with higher CD4+ T-cell counts were also more likely to receive a 2DR. Conclusion: Despite unrestricted access to ART in France, independently from HIV disease parameters, PWH born abroad were less likely to receive 2DRs as a maintenance regimen than those born in France. Qualitative data are needed to better understand physicians’ prescribing practices.
