Regulatory interplay between mir-181a-5p and estrogen receptor signaling cascade in breast cancer

The efficacy and side effects of endocrine therapy in breast cancer (BC) depend largely on estrogen receptor alpha (ERα) expression, the specific drug administered, and treatment scheduling. Although the benefits of endocrine therapy outweigh any adverse effects in the initial stages of BC, later- or advanced-stage tumors acquire resistance to treatments. The mechanisms underlying tumor resistance

Using integrated hydrological models to assess the impacts of climate change on discharges and extreme flood events in the upper yangtze river basin

Amongst the impacts of climate change, those arising from extreme hydrological events are expected to cause the greatest impacts. To assess the changes in temperature and precipitation and their impacts on the discharge in the upper Yangtze Basin from pre-industrial to the end of 21st century, four hydrological models were integrated with four global climate models. Results indicated that mean dis

Demarketing tourism for sustainability : Degrowing tourism or moving the deckchairs on the titanic?

Demarketing is generally recognized as that aspect of marketing that aims at discouraging customers in general or a certain class of customers in particular on either a temporary or permanent basis and has been increasingly posited as a potential tool to degrow tourism and improve its overall sustainability, particularly as a result of so-called overtourism. The paper provides an overview of the v

Spermatogonia Loss Correlates with LAMA 1 Expression in Human Prepubertal Testes Stored for Fertility Preservation

Fertility preservation for male childhood cancer survivors not yet capable of producing mature spermatozoa, relies on experimental approaches such as testicular explant culture. Although the first steps in somatic maturation can be observed in human testicular explant cultures, germ cell depletion is a common obstacle. Hence, understanding the spermatogonial stem cell (SSC) niche environment and i

Calcium Signaling in T Cells Is Induced by Binding to Nickel-Chelating Lipids in Supported Lipid Bilayers

Supported lipid bilayers (SLBs) are one of the most common cell-membrane model systems to study cell-cell interactions. Nickel-chelating lipids are frequently used to functionalize the SLB with polyhistidine-tagged ligands. We show here that these lipids by themselves can induce calcium signaling in T cells, also when having protein ligands on the SLB. This is important to avoid “false” signaling

Theoretical and Experimental Aspects of Current and Future Research on NbO2 Thin Film Devices

The present research front of NbO2 based memory, energy generation, and storage thin film devices is reviewed. Sputtering plasmas contain NbO, NbO2, and NbO3 clusters, affecting nucleation and growth of NbO2, often leading to a formation of nanorods and nanoslices. NbO2 (I41/a) undergoes the Mott topological transition at 1081 K to rutile (P42/mnm), yielding changes in the electronic structure, whThe present research front of NbO2 based memory, energy generation, and storage thin film devices is reviewed.

Sharing archaeological knowledge : The Interactive Reporting System

This study describes the development of a digital reporting system designed to provide archaeologists with a dynamic and interactive 3D web platform that can be used for describing in great detail records and activities undertaken across a multi-year field investigation campaign. The system was used to compose the archaeological report of a multi-year investigation and employed during the pandemic

Photon Mapping Superluminal Particles

One type of light source that remains largely unexplored in the field of light transport rendering is the light generated by superluminal particles, a phenomenon more commonly known as Cherenkov radiation. By re-purposing the Frank-Tamm equation for rendering, the energy output of these particles can be estimated and consequently mapped to photons, making it possible to visualize the brilliant blu

Development of bixin formulations. Extraction, microencapsulation, dispersibility and photostability

The aril that covers the seeds of the plant species Bixa orellana is composed of the natural colorants bixin and norbixin, phenolic components and native carbohydrates composed of hemicellulose, starch, and a small fraction of proteins. Bixin is a hydrophobic carotenoid that is water insoluble and is mostly used for coloring oil-based formulations. This thesis presents the development of different

Plant foods, dietary fibre and risk of ischaemic heart disease in the European prospective investigation into cancer and nutrition (EPIC) cohort

BACKGROUND: Epidemiological evidence indicates that diets rich in plant foods are associated with a lower risk of ischaemic heart disease (IHD), but there is sparse information on fruit and vegetable subtypes and sources of dietary fibre. This study examined the associations of major plant foods, their subtypes and dietary fibre with risk of IHD in the European Prospective Investigation into Cance

A Stronger Innate Immune Response During Hyperacute HIV-1 Infection is associated with ACUTE retroviral syndrome

BACKGROUND: Acute retroviral syndrome (ARS) is associated with HIV-1 subtype and disease progression, but the underlying immunopathological pathways are poorly understood. We aimed to elucidate associations between innate immune responses during hyperacute HIV-1 infection (hAHI) and ARS.METHODS: Plasma samples obtained from volunteers (≥18.0 years) before and during hAHI, defined as HIV-1 antibody

Therapeutic Recommendations for the Management of Older Adult Patients with Sjögren’s Syndrome

Primary Sjögren’s syndrome (SjS) is a systemic autoimmune disease most commonly diagnosed in middle-aged women. Although the disease can occur at all ages, it is diagnosed between 30 and 60 years of age in two-thirds of patients. In more than 20% of cases, the people are older than 65 years. In this review, we focus on the therapeutic management of primary SjS in older patients, following the rece
