Abstract

Glioblastoma (GB) is the most common and aggressive brain tumor. The treatment for newly diagnosed glioblastoma is surgical resection of the primary tumor mass, followed by radiotherapy and chemotherapy. However, recurrences frequently occur in proximity to the surgical resection area. In these cases, none of the current therapies is effective. Recently, implantable biomaterials seem to be a promising strategy against GB recurrence. Here, for the first time we combined the tailorable properties of soy-protein hydrogels with the versatility of drug-loaded liposomes to realize a hybrid biomaterial for controlled and sustained nanoparticles release. Hydrogel consisting of 18–20 % w/v soy-protein isolated were fabricated in absence of chemical cross-linkers. They were biodegradable (−10 % and −30 % of weight by hydrolytic and enzymatic degradation, respectively in 3 days), biocompatible (>95 % of cell viability after treatment), and capable of sustained release of intact doxorubicin-loaded liposomes (diffusion coefficient between 10−18 and 10 −19 m2 s−1). A proof-of-concept in a “donut-like” 3D-bioprinted model shows that liposomes released by hydrogels were able to diffuse in a model with a complex extracellular matrix-like network and a 3D structural organization, targeting glioblastoma cells. The combination of nanoparticles' encapsulation capabilities with the hydrogels' structural support and controlled release properties will provide a powerful tool with high clinical relevance that could be applicable for the treatment of other cancers, realizing patient-specific interventions.

Abstract

Enhanced signaling via RTKs in pulmonary hypertension (PH) impedes current treatment options because it perpetuates proliferation and apoptosis resistance of pulmonary arterial smooth muscle cells (PASMCs). Here, we demonstrated hyperphosphorylation of multiple RTKs in diseased human vessels and increased activation of their common downstream effector phosphatidylinositol 3'-kinase (PI3K), which thus emerged as an attractive therapeutic target. Systematic characterization of class IA catalytic PI3K isoforms identified p110[alpha] as the key regulator of pathogenic signaling pathways and PASMC responses (proliferation, migration, survival) downstream of multiple RTKs. Smooth muscle cell-specific genetic ablation or pharmacological inhibition of p110[alpha] prevented onset and progression of pulmonary hypertension (PH) as well as right heart hypertrophy in vivo and even reversed established vascular remodeling and PH in various animal models. These effects were attributable to both inhibition of vascular proliferation and induction of apoptosis. Since this pathway is abundantly activated in human disease, p110[alpha] represents a central target in PH., Introduction Pulmonary hypertension (PH) is a frequent phenomenon, which is characterized by limited treatment options and high mortality (1). PH may occur as a consequence of left heart disease, chronic [...]

9. Moving from servitization to digital servitization : Identifying the required dynamic capabilities and related microfoundations to facilitate the transition

Author

Chirumalla, K., Leoni, L., Oghazi, Pejvak, Chirumalla, K., Leoni, L., and Oghazi, Pejvak

Abstract

Many manufacturing companies are adopting servitization as a competitive business strategy to offer product-service combinations. The ongoing shift to digitalization and Industry 4.0 provides novel opportunities and benefits to industrial firms in this regard, and researchers termed the adoption of digital technologies to servitization as “digital servitization”. In order to successfully transition towards digital servitization, fundamental reconfiguration of resources, organizational structures, work practices, infrastructure, culture, etc. are required. Hence, this paper performs a systematic literature review on prior studies covering dynamic capabilities for servitization and digital servitization. The purpose is to identify and compare the dynamic capabilities needed to facilitate a transition from “traditional” servitization to digital servitization. In doing so, this paper presents an integrated framework of dynamic capabilities to enable digital servitization, providing 22 micro-foundations for servitization and digital servitization, as well as the key challenges and enablers related to the transition from one to the other.

Abstract

International audience; AimsDilated cardiomyopathy (DCM) is a complex disease where genetics interplay with extrinsic factors. This study aims to compare the phenotype, management, and outcome of familial DCM (FDCM) and non‐familial (sporadic) DCM (SDCM) across Europe.Methods and resultsPatients with DCM that were enrolled in the prospective ESC EORP Cardiomyopathy & Myocarditis Registry were included. Baseline characteristics, genetic testing, genetic yield, and outcome were analysed comparing FDCM and SDCM; 1260 adult patients were studied (238 FDCM, 707 SDCM, and 315 not disclosed). Patients with FDCM were younger (P < 0.01), had less severe disease phenotype at presentation (P < 0.02), more favourable baseline cardiovascular risk profiles (P ≤ 0.007), and less medication use (P ≤ 0.042). Outcome at 1 year was similar and predicted by NYHA class (HR 0.45; 95% CI [0.25–0.81]) and LVEF per % decrease (HR 1.05; 95% CI [1.02–1.08]. Throughout Europe, patients with FDCM received more genetic testing (47% vs. 8%, P < 0.01) and had higher genetic yield (55% vs. 22%, P < 0.01).ConclusionsWe observed that FDCM and SDCM have significant differences at baseline but similar short‐term prognosis. Whether modification of associated cardiovascular risk factors provide opportunities for treatment remains to be investigated. Our results also show a prevalent role of genetics in FDCM and a non‐marginal yield in SDCM although genetic testing is largely neglected in SDCM. Limited genetic testing and heterogeneity in panels provides a scaffold for improvement of guideline adherence.

Abstract

Background: The great technological advancements in the field of echocardiography have led to applications of stress echocardiography (SE) in almost all diagnostic fields of cardiology, from ischemic heart disease to valvular heart disease and diastolic function. However, the assessment of the right ventricle (RV) in general, and in particular in regard to the contractile reserve of the RV, is an area that has not been previously explored. We, therefore, propose a study to investigate the potential use of SE for the assessment of RV function in adult patients. Aims and objectives: The primary aim is to evaluate the feasibility of right ventricular SE. The secondary aim is to assess right ventricular contractile reserve. Matherials and Methods: Eighty-one patients undergoing a physical or dobutamine stress echocardiogram for cardiovascular risk stratification or chest pain were the subject of the study. An exercise leg cycle using a standard WHO protocol was used to simultaneously assess the right and left ventricular global and regional function as well as acquiring Doppler data. Whereas the patient had limitations in mobility, a dobutamine SE was be performed. We evaluated the average values of tricuspid annular plane systolic excursion (TAPSE), fractional area change (FAC), S-wave, systolic pulmonary artery pressure (sPAP), and right ventricle global longitudinal (free wall) strain (RVGLS) during baseline and at the peak of the effort. RV contractile reserve was defined as the change in RVGLS from rest to peak exercise. We also assessed the reproducibility of these measurements between two different expert operators (blind analysis). Results: At least 3 over 5 RV function parameters were measurable both during baseline and at the peak of the effort in 95% of patients, while all 5 parameters in 65% of our population, demonstrating an excellent feasibility. All RV-studied variables showed a statistically significant increase (P < 0.001) at peak compared to the baseline. The average percentage increases at peak were 31.1% for TAPSE, 24.8% for FAC, 50.6% for S-wave, 55.2% for PAPS, and 39.8% for RV strain. The reproducibility between operators at baseline and peak was excellent. Our study demonstrates that TAPSE, FAC, and S-wave are highly feasible at rest and at peak, while TAPSE, S-wave, and sPAP are the most reliable measurements during RV stress echo. Conclusion: RVGLS is useful in the assessment of RV contractile reserve in patients with good acoustic window. Further studies are needed to evaluate the impact of contrast echocardiography in improving RV contractile reserve assessment during SE.

Abstract

Enhanced signaling via RTKs in pulmonary hypertension (PH) impedes current treatment options because it perpetuates proliferation and apoptosis resistance of pulmonary arterial smooth muscle cells (PASMCs). Here, we demonstrated hyperphosphorylation of multiple RTKs in diseased human vessels and increased activation of their common downstream effector phosphatidylinositol 3′-kinase (PI3K), which thus emerged as an attractive therapeutic target. Systematic characterization of class IA catalytic PI3K isoforms identified p110α as the key regulator of pathogenic signaling pathways and PASMC responses (proliferation, migration, survival) downstream of multiple RTKs. Smooth muscle cell–specific genetic ablation or pharmacological inhibition of p110α prevented onset and progression of pulmonary hypertension (PH) as well as right heart hypertrophy in vivo and even reversed established vascular remodeling and PH in various animal models. These effects were attributable to both inhibition of vascular proliferation and induction of apoptosis. Since this pathway is abundantly activated in human disease, p110α represents a central target in PH.

41. Exploring Dynamic Capabilities to Facilitate a Smoother Transition fromServitization to Digital Servitization : A Theoretical Framework

Author

Leoni, L., Chirumalla, Koteshwar, Leoni, L., and Chirumalla, Koteshwar

Abstract

Many manufacturing companies are adopting servitization as a competitive business strategy to offer product-service combinations. The ongoing shift to digitalization and Industry 4.0 provides novel opportunities and benefits to industrial firms in this regard, and researchers termed the adoption of digital technologies to servitization as “digital servitization”. In order to successfully transition toward digital servitization, fundamental reconfiguration of resources, organizational structures, work practices, infrastructure, culture, etc. is required. The theory of Dynamic Capability provides an interesting analytical framework for holistically studying such strategic organizational changes and transformation. Hence, this chapter scans prior studies covering dynamic capabilities for servitization and digital servitization with related key enablers for the transition from one to another. The purpose is to identify and compare the dynamic capabilities needed to facilitate a smoother transition from “traditional forms” of servitization to digital servitization. In doing so, this chapter presents a theoretical framework of dynamic capabilities to enable digital servitization, providing 22 micro-foundations for servitization and digital servitization. The framework provides an important step for an enhanced understanding of how digital servitization can be built and nurtured from the currently ongoing servitization in industrial firms.

Abstract

Abstract Mechanisms of coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) differ as CABG provides surgical collateralization and may prolong life by preventing future myocardial infarctions (MI). However, CABG benefits are unclear in octogenarians, where surgical risk is often perceived as higher and PCI is chosen more liberally. We performed a meta-analysis of studies comparing outcomes in octogenarians with left main or multivessel disease who underwent CABG or PCI. Primary outcome was late mortality (> 5 years). Secondary outcomes were perioperative mortality, MI, re-revascularization (R-R), acute renal failure (ARF), and stroke. Fourteen studies with 17,942 patients were included. CABG was associated with lower late mortality (hazard ratio, HR: 1.23, 95% confidence interval: CI 1.05–1.44, p

Abstract

Prolyl 3-hydroxylation is a rare collagen type I post translational modification in fibrillar collagens. The primary 3Hyp substrate sites in type I collagen are targeted by an endoplasmic reticulum (ER) complex composed by cartilage associated protein (CRTAP), prolyl 3-hydroxylase 1 (P3H1) and prolyl cis/trans isomerase B, whose mutations cause recessive forms of osteogenesis imperfecta with impaired levels of alpha l (I)3Hyp986. The absence of collagen type I 3Hyp in wild type zebrafish provides the unique opportunity to clarify the role of the complex in vertebrate. Zebrafish knock outs for crtap and p3h1 were generated by CRISPR/Cas9. Mutant fish have the typical OI patients' reduced size, body disproportion and altered mineralization. Vertebral body fusions, deformities and fractures are accompanied to reduced size, thickness and bone volume. Intracellularly, collagen type I is overmodified, and partially retained causing enlarged ER cisternae. In the extracellular matrix the abnormal collagen type I assembles in disorganized fibers characterized by altered diameter. The data support the defective chaperone role of the 3-hydroxylation complex as the primary cause of the skeletal phenotype. (C) 2020 Elsevier B.V. All rights reserved.
