Eur Heart J Suppl

April 2024

Cardiologia 1-Emodinamica, Dipartimento Cardiotoracovascolare "A. De Gasperis", ASST Grande Ospedale Metropolitano Niguarda, Milano, Italy.

The issue of suboptimal drug regimen adherence in secondary cardiovascular prevention presents a significant barrier to improving patient outcomes. To address this, the utilization of drug combinations, specifically single pill combinations (SPCs) and polypills, was proposed as a strategy to simplify treatment regimens. This approach aims to enhance treatment accessibility, affordability, and adherence, thereby reducing healthcare costs and improving patient health.

Humans use space to think of and communicate the flow of time. This spatial representation of time is influenced by cultural habits so that in left-to-right reading cultures, short durations and past events are mentally positioned to the left of long durations and future events. The STEARC effect (Space Temporal Association of Response Codes) shows a faster classification of short durations/past events with responses on the left side of space and of long durations/future events with responses on the right side.

Calorie restriction protects against acute systemic LPS-induced inflammation.

Nutr Neurosci

November 2024

Universidade Federal do Rio Grande do Sul (UFRGS), Instituto de Ciências Básicas da Saúde (ICBS), Graduate Program in Biochemistry, Porto Alegre, Brazil.

Caloric restriction (CR) has been proposed as a nutritional strategy to combat chronic diseases, including neurodegenerative diseases, as well as to delay aging. However, despite the benefits of CR, questions remain about its underlying mechanisms and cellular and molecular targets. As inflammatory processes are the basis or accompany chronic diseases and aging, we investigated the protective role of CR in the event of an acute inflammatory stimulus.

Metamorphic fluids, faults, and shear zones are carriers of carbon from the deep Earth to shallower reservoirs. Some of these fluids are reduced and transport energy sources, like H and light hydrocarbons. Mechanisms and pathways capable of transporting these deep energy sources towards shallower reservoirs remain unidentified.

February 2024

Laboratory of Animal Ecology and Evolution (AnEcoEvo), Dipartimento di Agraria, Università degli Studi di Napoli Federico II, via Università, 100, 80055 Portici, Napoli, Italy.

The altitudinal distribution of animals and changes in their body size are effective indicators of climate change. Bats are sensitive to climate change due to their dependence on temperature during critical life stages. However, long-term studies documenting responses over extended periods are rare.

Article Synopsis
  • Anemia is common in patients with myelofibrosis (MF) and is worsened by the treatment drug ruxolitinib (RUX), with new cases of blast phase (BP) emerging in anemic patients not previously on this treatment.
  • A study of 886 MF patients treated with RUX found a BP incidence rate of 3.74 per 100 patient-years, with higher rates in patients who had varying levels of anemia; the most severe cases were in those dependent on transfusions.
  • The findings suggest that both pre-existing and treatment-induced anemia significantly increase the risk of BP development, indicating a need for better anemia treatments alongside MF therapies.

Top-down determinants of the numerosity-time interaction.

Sci Rep

November 2023

Department of Neuroscience, Psychology, Pharmacology, and Child Health, University of Florence, 50139, Florence, Italy.

Previous studies have reported that larger visual stimuli are perceived as lasting longer than smaller ones. However, this effect disappears when participants provide a qualitative judgment, by stating whether two stimuli have the "same or different" duration, instead of providing an explicit quantitative judgment (which stimulus lasts longer). Here, we extended these observations to the interaction between the numerosity of visual stimuli, i.

Iron-based enzymes efficiently activate molecular oxygen to perform the oxidation of methane to methanol (MTM), a reaction central to the contemporary chemical industry. Conversely, a very limited number of artificial catalysts have been devised to mimic this process. Herein, we employ the MIL-100(Fe) metal-organic framework (MOF), a material that exhibits isolated Fe sites, to accomplish the MTM conversion using O as the oxidant under mild conditions.

Introduction: Melanoma is the deadliest of all the skin cancers and its incidence is increasing every year in Europe. Patients with melanoma often present late to the specialist and treatment is delayed for many reasons (delay in patient consultation, misdiagnosis by general practitioners, and/or limited access to dermatologists). Beyond this, there are significant inequalities in skin cancer between population groups within the same country and between countries across Europe.

The built landscape of Nuragic Sardinia is an exceptional case for geostatistical analysis, allowing for a discussion of long-held assumptions and ideas. The function of nuraghi (ca. 1700-1100 BCE), the most prominent settled monument of the Sardinian Bronze Age, has been addressed via a multiplicity of landscape approaches, mainly relying on intuitive assessments of their spatial properties: nuraghi were assumed as means of territorial control.

Left-to-right readers classify faster past events with motor responses on the left side of space and future events with responses on the right side. This suggests a left-to-right spatial organization in the mental representation of time. Here, we show that the significance and reliability of this representation are linked to the joint use of temporal and spatial codes in the task at hand.
