Is fossil fuel combustion still a major contributor to atmospheric aerosol carbonaceous fractions in the Po Valley? Results from a C-based source apportionment.

C measurements on the carbonaceous fractions of atmospheric aerosol are an important tool for source apportionment. In this paper, a C-based source apportionment study was carried out on samples collected during winter 2021 at an urban background site in the Po Valley, one of the main pollution hot-spot areas in Europe. The samples were prepared using MISSMARPLE (MIlan Small-SaMple Automated Radiocarbon Preparation LinE for atmospheric aerosol), a recently developed sample preparation line for C measurements on atmospheric aerosol carbon fractions, specifically targeting small samples (about 50 μgC).

Exploiting Bacterial Pigmentation for Non-Destructive Detection of Seed-Borne Pathogens by Using Photoacoustic Techniques.

[The CCM Project "Phenotypic and molecular screening methodologies for the detection of coloniza-tions due to carbapenem-resistant Enterobacterales (CRE)"].

Carbapenem-resistant Enterobacterales (CREs) are globally considered to be a major threat to public health. National and international guidelines emphasize the importance of routine active surveillance policies to prevent their transmission. Consequently, screening for the evaluation of the status of colonization by CREs in hospitalized patients in Italy is considered essential to contain and control the spread of these microorganisms and their evolution towards infection.

[Sexually transmitted infections: a new hub&spoke model to control the increasing trend of STIs in Italy and prevent their spread].

The project "Experimentation of new integrated hospital-territory organizational models for the prevention and control of sexually transmitted infections: facilitated diagnostic-care pathways and offer of free targeted screening" was developed as part of the CCM 2019 programme, funded by the Italian Ministry of Health, being coordinated by the Italian National Health Institute (ISS), in collaboration with Sapienza University of Rome. Three clinical units located in Turin, Milan, and Cagliari, specialized in sexually transmitted infection (STI) diagnosis and treatment, and three highly specialized microbiology laboratories located in Trieste, Florence, and Palermo were involved.The objectives were to develop an innovative network model for the treatment of STIs based on multidisciplinary centres with high quality of care for STIs (hub-IST) and territorial structures (spoke-IST), to plan and test integrated facilitated care pathways for STIs, to evaluate the priorities, feasibility, and sustainability of prevention interventions.

Development of molecularly imprinted polymer-based electrochemical sensors for the detection of UV filters in aquatic ecosystems.

The presence of organic UV filters (OUVAs) has been detected worldwide in aquatic ecosystems. These pollutants, originating from various anthropogenic sources, can persist and transform within wastewater treatment plants (WWTPs), posing a potential environmental hazard. In this framework, this research presents electrochemical sensors based on molecularly imprinted polymers (MIPs) for the selective detection of Benzophenone-3 (BP-3) and Octocrylene (OC), two of the OUVA most spread in the aquatic environment, to overcome the analytical challenges related to the quantification of this class of contaminants in wastewater samples.

Minimally invasive type A aortic dissection repair: aortic valve resuspension with neomedia creation and the Ascyrus Medical Dissection Stent.

Type A aortic dissection is a life-threatening condition that requires immediate surgical intervention. The goal of traditional approaches is to treat the disease promptly, regardless of invasiveness, in order to achieve the quickest surgical outcome. This strategy has been shown to be associated with significant morbidity, extended recovery and postoperative complications.

Stroke thrombectomy in the elderly: A propensity score matched study on a nationwide real-world registry.

Introduction: Data on safety and efficacy of endovascular thrombectomy (EVT) for acute ischemic stroke in older patients are limited and controversial, and people aged 80 or older were under-represented in randomized trials. Our aim was to assess EVT effect for ischemic stroke patients aged ⩾80 at a nationwide level.

Patients And Methods: The cohort included stroke patients undergoing EVT from the Italian Registry of Endovascular Treatment in Acute Stroke (IRETAS).

New Structural Features of Isatin Dihydrothiazole Hybrids for Selective Carbonic Anhydrase Inhibitors.

Chemotherapeutic agents have remained the first-line treatment option for advanced-stage cancers when surgery or radiation therapy is not viable. Human carbonic anhydrase (hCA) isoforms IX and XII have been validated as anticancer targets. In particular, hCA IX is overexpressed in several solid tumor cells.

Exploiting High Order Magnetic Anisotropy for Advanced Magnetocaloric Refrigerants.

Three new 3 d-4 f complexes of general formula trans-[MF(py)][LnDOTA] (M=Cr or Co, Ln=Dy or Y, py=pyridine and DOTA=tetraazacyclododecane-N,N',N'',N'''-tetraacetate) have been synthetised. The fluoride-bridged systems were designed to achieve perfect tetragonal symmetry by combining four-fold symmetric lanthanide and transition metal building blocks. From single crystal measurements, an unprecedented switch of the tetragonal anisotropy of the Dy complexes has been observed.

Rational design and synthesis of novel N-benzylindole-based epalrestat analogs as selective aldose reductase inhibitors: An unexpected discovery of a new glucose-lowering agent (AK-4) acting as a mitochondrial uncoupler.

Diabetes mellitus is one of the most frequent metabolic diseases associated with hyperglycemia. Although antidiabetic drugs reduce hyperglycemia, diabetic patients suffer from abnormal fluctuations in blood glucose levels leading to the onset of long-term complications. Aldose reductase inhibitors are considered a promising strategy for regulating the occurrence of diabetic-specific comorbidities.

Bifunctional heterobimetallic 3d-4f [Co(II)-RE, RE = Dy, Eu, and Y] ionic complexes: modulation of the magnetic-luminescence behaviour.

This work reports the engineering and functional properties of an emerging class of heterobimetallic 3d-4f ionic complexes designed with cobalt and rare-earth (RE) metals. We present a comprehensive examination of the structural, magnetic, optical, and thermal properties of the heterobimetallic ionic complexes with the general formula [Co(hfa)][RE(hfa)tetraglyme] (RE = Dy, Eu, and Y), where the metal centres are coordinated by hexafluoroacetylacetonate (Hhfa = 1,1,1,5,5,5-hexafluoro-2,4-pentanedione), β-diketone and tetraglyme (2,5,8,11,14-pentaoxapentadecane) polyether. Structural analysis reveals an octahedral coordination geometry enveloping the cobalt(II) centre, characterized by inherent symmetry properties consistent across the derivatives, while a capped square-antiprism coordination polyhedron is observed for the RE ions.

Unsupervised clustering analysis-based characterization of spatial profiles of inaccuracy in apparent diffusion coefficient values with varying acquisition plan orientation and diffusion weighting gradient direction - a large multicenter phantom study.

This large multicenter study of 37 magnetic resonance imaging scanners aimed at characterizing, for the first time, spatial profiles of inaccuracy (namely, Δ-profiles) in apparent diffusion coefficient (ADC) values with varying acquisition plan orientation and diffusion weighting gradient direction, using a statistical approach exploiting unsupervised clustering analysis. A diffusion-weighted imaging (DWI) protocol (b-value: 0-200-400-600-800-1000 s mm) with different combinations of acquisition plan orientation (axial/sagittal/coronal) and diffusion weighting gradient direction (anterior-posterior/left-right/feet-head) was acquired on a standard water phantom. For each acquisition setup, Δ-profiles along the 3 main orthogonal directions were characterized by fitting data with a second order polynomial function ().

Synthesis of Chromene-linked Bis-indole Derivatives as Selective Tumor-associated Carbonic Anhydrase IX Inhibitors.

Background: Sulfonamide derivatives are well-reported hCA IX inhibitors; however, they inhibit all types of hCA without any selectivity, leading to severe adverse effects. Hence, developing a novel nonsulfonamide class of tumor-associated hCA IX inhibitors through non-classical inhibition may provide greater selectivity and better pharmacokinetics.

Objective: The objective of this study was to develop non-sulfonamide derivatives as potential human carbonic anhydrase (hCA) inhibitors and develop a new series of chromene-linked bis-indole derivatives.

Phase-dependent polymerization isomerism in the coordination complexes of a flexible bis(β-diketonato) ligand.

First prepared in the late 70s, the pro-ligand 1,3-bis(3,5-dioxo-1-hexyl)benzene (Hbdhb) contains two acetoacetyl terminations linked to a central 1,3-phenylene unit through dimethylene bridges. Since each termination can be either in diketonic or keto-enolic form, in organic solution it exists as a mixture of three spectroscopically resolvable tautomers. In the presence of pyridine, Co and the bdhb anion form a crystalline dimeric compound with formula [Co(bdhb)(py)] (2) and a Co⋯Co separation of more than 11 Å.

War is undermining soil health and availability more than urbanisation.

Ever since the Earth has witnessed the dawn of mankind it has had to deal with conflicts and their consequences. The number of ongoing conflicts continues to increase year by year, as does the power of the weapons at stake. Consequently, also increasing is the impact of warfare on the total environment, which is already in crisis due to climate change and exponential population growth.

High-Dimensional Bayesian Semiparametric Models for Small Samples: A Principled Approach to the Analysis of Cytokine Expression Data.

In laboratory medicine, due to the lack of sample availability and resources, measurements of many quantities of interest are commonly collected over a few samples, making statistical inference particularly challenging. In this context, several hypotheses can be tested, and studies are not often powered accordingly. We present a semiparametric Bayesian approach to effectively test multiple hypotheses applied to an experiment that aims to identify cytokines involved in Crohn's disease (CD) infection that may be ongoing in multiple tissues.
