A phase Ib/II study of HER3-targeting lumretuzumab in combination with carboplatin and paclitaxel as first-line treatment in patients with advanced o…

2019

Purpose This study investigated the safety and clinical activity of lumretuzumab, a humanised antihuman epidermal growth factor receptor 3 (HER3) monoclonal antibody, in combination with carboplatin and paclitaxel in first-line treatment of patients with squamous non-small cell lung cancer (sqNSCLC). HER3 ligand heregulin and HER3 protein expression were evaluated as potential biomarkers of clinical activity. Patients and methods This open-label, phase Ib/II study enrolled patients receiving lumretuzumab at 800 mg (flat) in combination with carboplatin (area under the curve (AUC) 6 mg/mL×min) and paclitaxel (200 mg/m 2) administered intravenously on a every 3-week schedule. Adverse event (A…

Mental Health and Adherence to COVID-19 Protective Behaviors among Cancer Patients during the COVID-19 Pandemic: An International, Multinational Cros…

2021

Simple Summary Whilst information on the impact of COVID-19 on cancer care continues to increase exponentially, little is known about the impact of COVID-19 on the mental health and coping behaviors of cancer patients. This study constitutes a sub-study of a large international survey conducted during the first wave of the pandemic, looking specifically at the impact of COVID-19 on the mental health and protective behaviors of cancer participants, compared to non-cancer participants. It also explored whether cancer participants perceived COVID-19 as a bigger threat compared to their cancer and whether this perception affected their psychological outcomes, such as their perceived level of st…

Association between Pterostilbene and Quercetin Inhibits Metastatic Activity of B16 Melanoma

2005

AbstractInhibition of cancer growth by resveratrol (trans-3,5,4'trihydroxystilbene; RESV), a phytoalexin present in many plant species, is limited by its low bioavailability. Pterostilbene (3,5-dimethoxy-4'-hydroxystilbene; PTER) and quercetin (3,3',4',5,6-pentahydroxyflavone; QUER), two structurally related and naturally occurring small polyphenols, show longer half-life in vivo. In vitro growth of highly malignant B16 melanoma F10 cells (B16M-F10) is inhibited (56%) by short-time exposure (60 min/day) to PTER (40 μM) and QUER (20 μM) (approximate mean values of plasma concentrations measured within the first hour after intravenous administration of 20 mg/kg of each polyphenol). Intravenou…

Key Enzymes in Pyrimidine Synthesis, CAD and CPS1, Predict Prognosis in Hepatocellular Carcinoma

2021

Simple Summary Individual patients with liver cancer have a highly variable clinical course. Hence, there is an urgent need to identify new prognostic markers to determine prognosis and select specific therapies. Expression of two key enzymes in pyrimidine synthesis was analyzed in a large, well-characterized cohort of patients with liver cancer. Dysregulated expression of these enzymes was associated with shorter survival of the patients. A combined score of both markers was found to be a statistically independent prognostic marker. Abstract Patients with hepatocellular carcinoma (HCC) have a highly variable clinical course. Therefore, there is an urgent need to identify new prognostic mar…

Functional and Therapeutic Significance of Tumor-Associated Macrophages in Colorectal Cancer

2022

The role of the tumor microenvironment (TME) in the progression of colorectal cancer (CRC) and its acquisition of resistance to treatment become the research hotspots. As an important component of TME, the tumor-associated macrophages (TAMs) regulate multiple critical oncogenic processes, namely, occurrence, proliferation, metastasis, and drug resistance in CRC. In this review, we have discussed the functional and therapeutic significance of TAMs in CRC. M1 macrophages act as the tumor suppressor while M2 macrophages promote CRC. The polarization of TAMs is mainly regulated by the pathways such as NFKB1 pathways, STAT3 pathways, WNT5A pathways, and PI3K pathways in CRC. Furthermore, the M2 …

Changes in gene expression linked with adult reproductive diapause in a northern malt fly species: a candidate gene microarray study

2010

Abstract Background Insect diapause is an important biological process which involves many life-history parameters important for survival and reproductive fitness at both individual and population level. Drosophila montana, a species of D. virilis group, has a profound photoperiodic reproductive diapause that enables the adult flies to survive through the harsh winter conditions of high latitudes and altitudes. We created a custom-made microarray for D. montana with 101 genes known to affect traits important in diapause, photoperiodism, reproductive behaviour, circadian clock and stress tolerance in model Drosophila species. This array gave us a chance to filter out genes showing expression…

An Analytic Hierarchy Process for The Evaluation of Transport Policies to Reduce Climate Change Impacts

2007

Transport is the sector with the fastest growth of greenhouse gases emissions, both in developed and in developing countries, leading to adverse climate change impacts. As the experts disagree on the occurrence of these impacts, by applying the analytic hierarchy process (AHP), we have faced the question on how to form transport policies when the experts have different opinions and beliefs. The opinions of experts have been investigated by a means of a survey questionnaire. The results show that tax schemes aiming at promoting environmental-friendly transport mode are the best policy. This incentives public and environmental-friendly transport modes, such as car sharing and car pooling.

Properties of amphiphilic terminally substituted conjugated nonaene- and 2-docosylnonaene carboxylic acids in monolayers at the air-water interface

1991

was a lo-' M Co(NO,), + lo-' M CH,COONa solution, with pH 7.5; the counter electrode was a Pt sheet, conveniently located in the electrochemical cell. After deposition, the electrochemical/electrochromic properties of the films were analyzed in degassed lo-' M KOH electrolyte, in a three electrode cell (Pt wire counter electrode, saturated calomel reference electrode) with optical windows. A PAR 173 potentiostat-galvanostat associated with a PAR 175 function generator was used in the electrochemical experiments. Data were recorded in a analogical X-Y (X-T) recorder. Monochromatic transmission (He-Ne laser, A = 632.8 nm) was recorded in situ, by means of a versatile optical bench; spectral t…

Algunas reflexiones acerca de la stjue de 9 de julio de 2020 sobre los pactos novatorios en materia de cláusulas suelo

2021

The Sentence of the Court of Justice of the European Union of July 9, 2020 comes to answer the five questions that, in its preliminary question, the Court of First Instance and Instruction No. 3 of Teruel asks about the validity of the new agreements in the context of the floor clauses, establishing jurisprudential doctrine on this matter about which our Supreme Court had previously ruled in its Judgments of October 16, 2017, in the sense of considering the agreed floor clause null as a consequence of the novation agreement and, subsequently, those of April 11, 2018 and September 13, 2018 in the opposite direction, declaring that the novation agreement was valid. It is a long-awaited and in…
