Evaluation of Risk Factors Influencing Tick-Borne Infections in Livestock Through Molecular Analyses.

Microorganisms

January 2025

Istituto Zooprofilattico Sperimentale del Mezzogiorno, Department of Animal Health, 80055 Portici, Italy.

Climate changes and human-related activities are identified as major factors responsible for the increasing distribution and abundance of vectors worldwide and, consequently, of vector-borne diseases (VBDs). Farmed animals, during grazing or in establishments with the absence of biosecurity measures, can easily be exposed to wildlife showing high-risk of contagion of several infectious diseases, including VBDs. Furthermore, livestock represents an interface between wildlife and humans, and thus, promoting the transmission pathway of VBDs.

Background: Insulin resistance (IR) and serum uric acid (SUA) are closely interconnected: SUA contributes to adversely affects the insulin signaling pathway and contributes to IR, while IR is a known predictor for the development of hyperuricemia. The triglyceride (TG) to high-density lipoprotein cholesterol (HDL-C) ratio has been proposed as an easily obtainable marker for IR. This research aimed to investigate the interaction between IR and glomerular filtration rate (GFR)-adjusted uricemia (SUA/GFR ratio) in determining CV risk in a large population cohort study.

Background: Although little is yet known about the long-term maintenance of very low-energy ketogenic therapy (VLEKT) effects on body composition, muscle strength and inflammation, it is plausible to assume that changes may occur, particularly during the steps following the ketogenic step, due to the loss of the protective effects of ketones and the concomitant reintroduction of carbohydrates. For this reason, the present study aimed to evaluate the effects of supplementation with 8 g per day of essential amino acids (EAAs) on these parameters.

Methods: A total of 68 women of reproductive age and with grade I obesity who had completed 45 days of the ketogenic phase with VLEKT (KeNuT protocol) and 40 days of non-ketogenic phase of KeNuT protocol with VLEKT (phase 3, fruit reintroduction) were included in the study.

January 2025

Dipartimento di Neuroscienze, Riabilitazione, Oftalmologia, Genetica e Scienze Materno- Infantili (DINOGMI), Università Degli Studi Di Genova, Genoa, Italy.

Background: Over the past two decades there has been a remarkable advance in the management of juvenile idiopathic arthritis (JIA), which has led to considerable improvement in prognosis. In 2018, the introduction of the treat-to-target (T2T) strategy in JIA has been advocated to further ameliorate disease outcome. To provide a benchmark for comparing future outcomes in the "T2T era", this study investigates the percentage of JIA patients who achieved clinical inactive disease (CID) in the decade that preceded the publication of the T2T recommendations in JIA.

Mitigation of Self-p-Doping and Off-Centering Effect in Tin Perovskite via Strontium Doping.

ACS Energy Lett

January 2025

Helmholtz-Zentrum Berlin für Materialien und Energie GmbH, Hahn-Meitner Platz 1, 14109 Berlin, Germany.

Tin-based perovskite solar cells offer a less toxic alternative to their lead-based counterparts. Despite their promising optoelectronic properties, their performances still lag behind, with the highest power conversion efficiencies reaching around 15%. This efficiency limitation arises primarily from electronic defects leading to self-p-doping and stereochemical activity of the Sn(II) ion, which distorts the atomic arrangement in the material.

CD4FOXP3Exon2 regulatory T cell frequency predicts breast cancer prognosis and survival.

Sci Adv

January 2025

Istituto per l'Endocrinologia e l'Oncologia Sperimentale "G. Salvatore", IEOS-CNR, Napoli, Italy.

CD4FOXP3 regulatory T cells (T) suppress immune responses to tumors, and their accumulation in the tumor microenvironment (TME) correlates with poor clinical outcome in several cancers, including breast cancer (BC). However, the properties of intratumoral T remain largely unknown. Here, we found that a functionally distinct subpopulation of T, expressing the FOXP3 Exon2 splicing variants, is prominent in patients with hormone receptor-positive BC with poor prognosis.

ESMO Open

January 2025

Uro-Gynecologic Oncology Unit, Istituto Nazionale Tumori IRCCS Fondazione G. Pascale, Naples, Italy. Electronic address:

Background: Ovarian cancer (OvC) constitutes significant management challenges primarily due to its late-stage diagnosis and the development of resistance to chemotherapy. The standard treatment regimen typically includes carboplatin and paclitaxel, with the addition of poly (ADP-ribose) polymerase inhibitors for patients with high-grade serous ovarian cancer (HGSOC) harboring BRCA1/2 mutations. However, the variability in treatment responses suggests the need to investigate factors beyond BRCA1/2 mutations, such as DNA repair mechanisms and epigenetic alterations.

Celestial Holography Revisited.

Phys Rev Lett

December 2024

Dipartimento di Fisica "Ettore Pancini," Università degli Studi di Napoli Federico II, Monte Sant'Angelo, Via Cintia, 80126 Napoli, Italy; INFN, Sezione di Napoli, Monte Sant'Angelo, Via Cintia, 80126 Napoli, Italy; and Scuola Superiore Meridionale, Università degli Studi di Napoli Federico II, Largo San Marcellino 10, 80138 Napoli, Italy.

We revisit the prescription commonly used to define holographic correlators on the celestial sphere of Minkowski space as an integral transform of flat space scattering amplitudes. We propose a new prescription according to which celestial holographic correlators are given by the Mellin transform of bulk time-ordered correlators with respect to the radial direction in the hyperbolic slicing of Minkowski space, which are then extrapolated to the celestial sphere along the hyperbolic directions. This prescription is analogous to the extrapolate definition of holographic correlators in AdS/CFT and, like in AdS, is centered on (off-shell) correlation functions as opposed to (on-shell) S-matrix elements.

In the last years, it has been proved that some viruses are able to re-structure chromatin organization and alter the epigenomic landscape of the host genome. In addition, they are able to affect the physical mechanisms shaping chromatin 3D structure, with a consequent impact on gene activity. Here, we investigate with polymer physics genome re-organization of the host genome upon SARS-CoV-2 viral infection and how it can impact structural variability within the population of single-cell chromatin configurations.

Electronic address:

Hypothesis: Ellipsoidal particles confined at liquid interfaces exhibit complex self-assembly due to quadrupolar capillary interactions, favouring either tip-to-tip or side-to-side configurations. However, predicting and controlling which structure forms remains challenging. We hypothesize that introducing a polymer-based soft shell around the particles will modulate these capillary interactions, providing a means to tune the preferred self-assembly configuration based on particle geometry and shell properties.
