C1q–Ha matrix regulates the local synthesis of hyaluronan in malignant pleural mesothelioma by modulating has3 expression
2021
Increased hyaluronic acid (HA) production is often associated with cancer progression. In malignant pleural mesothelioma (MPM), HA is found at elevated levels in pleural effusions and sera of patients, and it has been widely debated whether MPM cells are able to produce HA by themselves or through the release of growth factors stimulating other cells. Another key component of the MPM microenvironment is C1q, which can act as a pro-tumorigenic factor favoring cell adhesion, migration and proliferation. The aim of the current study was to prove that MPM primary cells are able to synthesize HA and to inquire the stimulus given by C1q&ndash
Biological Effects of New Hydraulic Materials on Human Periodontal Ligament Stem Cells.
2019
Background: The aim of this study was: to evaluate the biological properties of new hydraulic materials: Bio-C Repair and Bio-C Sealer. Methods: Periodontal ligament stem cells were exposed to several dilutions of Bio-C Repair and Bio-C Sealer. The ion release profile and pH were determined. Metabolic activity, cell migration and cell survival were assessed using the 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT), wound-healing assays and Annexin assays, respectively. Cells were cultured in direct contact with the surface of each material. These were then analyzed via scanning electron microscopy (SEM) and energy dispersive X-ray (EDX). Statistical differences were ass…
Effect of Fibrin Sealant on Seroma Formation Post-Incisional Hernia Repair
2020
Background: Development of seroma after incisional hernia repair is a common complication. Our study aims to compare the outcomes of sublay incisional hernia repairs with or without spray instillation of fibrin glue. Methods: We enrolled fifty patients undergoing incisional hernia repair. In all patients a suction drain was placed in the subcutaneous space. In one group (FG) 4 ml fibrin glue was instilled in the subcutaneous space. In the control group (C) patients did not receive any prevention measure. Wounds fluids were collected on post-operative day 1 (POD) and once daily until drain removal. All patients were followed up by ultrasound on POD 15, 20, 40, 60. Results: Drain fluid produc…
Monitoring Risk Factors and Improving Adherence to Therapy in Patients With Chronic Kidney Disease (Smit-CKD Project): Pilot Observational Study
2022
Background Chronic kidney disease is a major public health issue, with about 13% of the general adult population and 30% of the elderly affected. Patients in the last stage of this disease have an almost uniquely high risk of death and cardiovascular events, with reduced adherence to therapy representing an additional risk factor for cardiovascular morbidity and mortality. Considering the increased penetration of mobile phones, a mobile app could educate patients to autonomously monitor cardiorenal risk factors. Objective With this background in mind, we developed an integrated system of a server and app with the aim of improving self-monitoring of cardiovascular and renal risk factors and…
Paperitehtaan jätevesien käsittely termofiilisellä aktiiviliete- ja biofilmiprosessilla
2005
Monilla teollisuudenaloilla muodostuu kuumia jätevesiä, jotka jäähdytetään biologista kä- sittelyä varten. Käsittely totuttua korkeammassa lämpötilassa voi tuoda taloudellisia sekä prosessin toimintaan liittyviä etuja. Kuitenkin useimpien termofiilisestä jätevedenkäsittelystä saatujen kokemusten mukaan lietteen erotus on vaikeampaa kuin tavanomaisessa jäteveden käsittelyssä. Myös joidenkin liukoisten aineiden poisto voi monimutkaistua. Tämän tutkimuksen tavoite oli verrata termofiilisen (55 °C) aktiiviliete- ja biofilmiprosessien toimintaa pilot-mittakaavassa. Toimintaa verrattiin myös täyden mittakaavan mesofiiliseen (35 °C) aktiivilieteprosessiin, mutta painotus on termofiilisten prosessi…
Estudio experimental in vitro de la unión de dos compuestos híbridos a distintos cementos de resina compuesta
2019
La actual exigencia de máxima conservación de tejido dental sano ha potenciado el uso de restauraciones prostodóncicas parciales frente a las de recubrimiento total. La ausencia de retención mecánica obliga a un cementado adhesivo de dichas restauraciones sobre los dientes. En los últimos años han surgido nuevos materiales, como los compuestos híbridos con intención de mejorar las propiedades mecánicas y estéticas de los materiales utilizados hasta el momento como son las porcelanas y las resinas compuestas. Se presenta una revisión bibliográfica de los materiales sometidos a este estudio: cerámicas dentales, resinas compuestas, cementos de resina compuesta y materiales híbridos. El objetiv…
Complement Protein C1q Binds to Hyaluronic Acid in the Malignant Pleural Mesothelioma Microenvironment and Promotes Tumor Growth
2017
C1q is the first recognition subcomponent of the complement classical pathway, which acts towards the clearance of pathogens and apoptotic cells. C1q is also known to modulate a range of functions of immune and non-immune cells, including their involvement in placental development and sensorial synaptic pruning. We have recently shown that C1q can promote tumour by encouraging their adhesion, migration and proliferation in addition to angiogenesis and metastasis. In this study, we have examined the role of C1q in the microenvironment of malignant pleuric mesothelioma (MPM), a rare form of cancer commonly associated with exposure to asbestos. We found that C1q was highly expressed in all MPM…
A multicenter phase 1 study of solitomab (MT110, AMG 110), a bispecific EpCAM/CD3 T-cell engager (BiTE®) antibody construct, in patients with refract…
2018
ABSTRACT We assessed the tolerability and antitumor activity of solitomab, a bispecific T-cell engager (BiTE®) antibody construct targeting epithelial cell adhesion molecule (EpCAM). Patients with relapsed/refractory solid tumors not amenable to standard therapy received solitomab as continuous IV infusion in a phase 1 dose-escalation study with six different dosing schedules. The primary endpoint was frequency and severity of adverse events (AEs). Secondary endpoints included pharmacokinetics, pharmacodynamics, immunogenicity, and antitumor activity. Sixty-five patients received solitomab at doses between 1 and 96 µg/day for ≥28 days. Fifteen patients had dose-limiting toxicities (DLTs): e…
Adherence to omalizumab: A multicenter “real-world” study
2020
Background: Adherence to medications is crucial in patients with severe asthma in light of the negative clinical impact and costs of non-adherence. Adherence to omalizumab has not been well studied in real-world settings. The aim of this study was to assess adherence to omalizumab and evaluate treatment effectiveness in relation to adherence. Methods: This was a retrospective, observational, and multicenter real-world study. Omalizumab dose, timing of administration, and duration of treatment ( 4 years) were analyzed. Adherence was evaluated by examining rates of expected and missing doses. Good adherence (10% doses missed) were determined. For effectiveness in relation to adherence of omal…
IL-2 Expression in Activated Human Memory FOXP3(+) Cells Critically Depends on the Cellular Levels of FOXP3 as Well as of Four Transcription Factors …
2012
The human CD4(+)FOXP3(+) T cell population is heterogeneous and consists of various subpopulations which remain poorly defined. Anergy and suppression are two main functional characteristics of FOXP3(+)Treg cells. We used the anergic behavior of FOXP3(+)Treg cells for a better discrimination and characterization of such subpopulations. We compared IL-2-expressing with IL-2-non-expressing cells within the memory FOXP3(+) T cell population. In contrast to IL-2-non-expressing FOXP3(+) cells, IL-2-expressing FOXP3(+) cells exhibit intermediate characteristics of Treg and Th cells concerning the Treg cell markers CD25, GITR, and Helios. Besides lower levels of FOXP3, they also have higher levels…
