The first full study of heavy metal(loid)s in western-European hedgehogs (Erina...

The western-European hedgehog (Erinaceus europaeus) is an insectivore with a wide distribution in Portugal and a potential tool for biomonitoring relevant One Health hazards, including heavy metal(loid)s’ pollution. The aim of this study was to positively contribute to the current knowledge about the metal(loid) pollution in Portugal. Forty-six hedgehogs (from rescue centres; with known provenance) were necrops...

Characterization of take-away/delivery menus during the second lockdown in Port...

One-pot intercalation strategy for the encapsulation of a CO-releasing organome...

The photoactivatable CO‐releasing molecule (photoCORM) [Mo(CO)3(CNCH2COOH)3] (ALF795) has been incorporated into a Zn,Al layered double hydroxide (LDH) host by a coprecipitation synthesis strategy. Powder X‐ray diffraction (PXRD) of the resultant material Zn,Al‐ALF795 showed that the ALF795 guest molecules assembled into a monolayer to give a basal spacing of 16.0 Å. FTIR and 13C{1H} CP MAS NMR spectroscopy con...

A One Health Perspective on Q Fever: Part 1

Q fever is a worldwide zoonotic infectious disease caused by Coxiella burnetii and ruminants, namely, cattle, sheep, and goats, are known to be the main reservoir for human infection. C. burnetii infection in animals can result in epizootic abortions which are often associated with vast bacteria shedding in birth fluids and placentas. Human infections mainly occur in persons handling infected animals and their ...

A One Health Perspective on Q Fever: Part 2

Q fever, a widespread zoonotic disease caused by Coxiella burnetiid, produces a complex and polymorphic disease in humans. As a zoonotic disease, control in animals will influence the level of disease seen in humans, thus resulting in interesting one health perspectives for disease control. Here the authors describe the clinical manifestations in animals and humans, as well as the current diagnostic methods ava...

A Nationwide Seroepidemiologic Study on Q Fever Antibodies in Sheep of Portugal

Introduction: Q fever is an almost global zoonotic disease caused by Coxiella burnetii. Human infections can produce acute and chronic disease that can lead to abortions and stillbirths in pregnant women, usually infected by the inhalation of C. burnetii-contaminated aerosols or through consumption of contaminated products. Sheep are one of the primary animal reservoirs with disease being associated with vast s...

Study of the interactions of bovine serum albumin with a molybdenum(II) carbony...

Therapy with inhaled carbon monoxide (CO) is being tested in human clinical trials, yet the alternative use of prodrugs, CO-Releasing Molecules (CORMs), is conceptually advantageous. These molecules are designed to release carbon monoxide in specific tissues, in response to some locally expressed stimulus, where CO can trigger a cytoprotective response. The design of such prodrugs, mostly metal carbonyl complex...

Sustainability and cultural heritage buildings

[Excerpt from Introduction] Conservation of cultural heritage buildings is a demand from society, which recognizes this heritage as a part of their identity, but it is also an economical issue. In Europe, tourism accounts for 10% of the GDP and 12% of the employment, if linked sectors are considered [x.1]. The EU is the world's number one tourist destination, with 40 % of arrivals in the world and with 7 Europe...

Catalytic isomerisation of alpha-pinene oxide in the presence of ETS-10 support...

Ferrocenium ions, [Fc](+), have been immobilised in the microporous titanosilicate ETS-10 by ion exchange of Na+/K+ ions under hydrothermal conditions. The resultant hybrid inorganic-organometallic (ETS-10/[Fc](+)) material was characterised by elemental analysis, diffuse reflectance UV-Vis spectroscopy, FT-IR spectroscopy, powder X-ray diffraction, scanning electron microscopy, and thermogravimetric analysis. ...

Spontaneous CO release from RuII(CO)2-protein complexes in aqueous solution, ce...

We demonstrate that Ru(II)(CO)2-protein complexes, formed by the reaction of the hydrolytic decomposition products of [fac-RuCl(κ(2)-H2NCH2CO2)(CO)3] (CORM-3) with histidine residues exposed on the surface of proteins, spontaneously release CO in aqueous solution, cells, and mice. CO release was detected by mass spectrometry (MS) and confocal microscopy using a CO-responsive turn-on fluorescent probe. These fin...
