    Abstract Psoriasis has emerged as a systemic disease characterized by skin and joint manifestations as well as systemic inflammation and cardiovascular comorbidities. Many progresses have been made in the comprehension of the immunological mechanisms involved in the exacerbation of psoriatic plaques, and initial studies have investigated the mechanisms that lead to extracutaneous disease manifestations, including endothelial disfunction and cardiovascular disease. In the past decade, the involvement of gut dysbiosis in the development of pathologies with inflammatory and autoimmune basis has clearly emerged. More recently, a major role for the skin microbiota in establishing the immunological tolerance in early life and as a source of antigens leading to cross-reactive responses towards self-antigens in adult life has also been evidenced. Gut microbiota can indeed be involved in shaping the immune and inflammatory response at systemic level and in fueling inflammation in the cutaneous and vascular compartments. Here, we summarized the microbiota-mediated mechanisms that, in the skin and gut, may promote and modulate local or systemic inflammation involved in psoriatic disease and endothelial dysfunction. We also analyze the emerging strategies for correcting dysbiosis or modulating skin and gut microbiota composition to integrate systemically existing pharmacological therapies for psoriatic disease. The possibility of merging systemic treatment and tailored microbial modifying therapies could increase the efficacy of the current treatments and potentially lower the effect on patient's life quality.

    Abstract Antiphospholipid syndrome (APS) is an acquired thrombophilic disorder related to the presence of antiphospholipid antibodies (LAC, anticardiolipin, anti Beta2-glycoprotein) known to cause venous and arterial thrombosis and recurrent pregnancy loss. Skin disorder is a frequent finding usually due to vascular thrombosis involving the dermal layer and can be either localized or widespread causing necrosis and ulceration of the skin, without histological evidence of vasculitis. We present a case of a woman with APS with both arterial and venous thrombotic involvement associated with an atypical dermatological manifestation histologically consistent with a pauci-inflammatory intermediate-deep dermal arteriolar platelet-mediated thrombosis that appeared despite anticoagulation with warfarin and responding to the addition of antiplatelet therapy.

    Abstract Benzoic acid (BA) and its derivatives are very attractive because of their pharmacological properties, such as antioxidant, radical-regulating, antiviral, antitumor, anti-inflammatory, antimicrobial and antifungal. Syndiotactic polystyrene (sPS) and poly(2,6-dimethyl-1,4-phenylene)oxide (PPO) films exhibiting co-crystalline phases with BA were prepared and characterized by WAXD, FTIR and polarized FTIR measurements. The FTIR measurements clearly showed that BA was present mainly as a dimer in the crystalline channels of the ε form of sPS as well as in the α form of PPO, as generally occurs not only in the solid state but also in organic dilute solutions. BA was instead present as isolated molecules in the crystalline cavities of the δ form of sPS. In fact, the FTIR spectra of BA guest molecules exhibited vibrational peaks close to those of BA in its vapor phase. Hence, the nanoporous-crystalline δ form of sPS not only avoids additive aggregation but also leads to the separation of dimeric molecules and the segregation of monomeric BA.

    Abstract Films exhibiting nanoporous-crystalline (NC) phases of poly(2,6-dimethyl-1,4-phenylene) oxide (PPO), which are highly effective to absorb apolar organic guest molecules, are also able to absorb polar molecules (like alcohols and carboxylic acids) but only from concentrated organic solutions. NC PPO films, which do not absorb alcohols and carboxylic acids from diluted aqueous solutions, exhibits a huge uptake (even above 30 wt %) of benzyl alcohol (BAL) and benzoic acid (BA), if BA is obtained by spontaneous room temperature oxidation of BAL in aqueous solution. This phenomenon is rationalized by an easy uptake, mainly by the PPO intrahelical crystalline empty channels, of a BAL/BA 1/1 hydrogen-bonded dimer. This huge uptake of BAL/BA dimer by NC PPO films, which is also fast for films exhibiting the orientation of the crystalline helices perpendicular to the film plane (c

    Abstract The dependence of polymer film transparency on different kinds of planar orientations of nanoporous-crystalline (NC) phases of syndiotactic polystyrene (sPS) and poly(2,6-dimethyl-1,4-phenylene)oxide (PPO) is described. The two polymers exhibit opposite behavior: film transparency is improved for sPS and PPO by orientations of the chain axes of the NC phases being parallel (c∥) and perpendicular (c⊥) to the film plane, respectively. This behavior can be rationalized by the negative and positive birefringence of sPS and PPO chains, respectively. In fact, to maximize transparency, the refractive index of the NC phase along the perpendicular to the film plane has to be increased to come closer to that of the corresponding amorphous phase. This can be pursued by controlling the orientation of the NC phases and hence of the associated refractive index ellipsoids.

    Abstract Endothelial damage is recognized as the initial step that precedes several cardiovascular diseases (CVD), such as atherosclerosis, hypertension, and coronary artery disease. It has been demonstrated that the best treatment for CVD is prevention, and, in the frame of a healthy lifestyle, the consumption of vegetables, rich in bioactive molecules, appears effective at reducing the risk of CVD. In this context, the large amount of agri-food industry waste, considered a global problem due to its environmental and economic impact, represents an unexplored source of bioactive compounds. This review provides a summary regarding the possible exploitation of waste or by-products derived by the processing of three traditional Italian crops—apple, pear, and sugar beet—as a source of bioactive molecules to protect endothelial function. Particular attention has been given to the bioactive chemical profile of these pomaces and their efficacy in various pathological conditions related to endothelial dysfunction. The waste matrices of apple, pear, and sugar beet crops can represent promising starting material for producing “upcycled” products with functional applications, such as the prevention of endothelial dysfunction linked to cardiovascular diseases.

    Abstract Based on a commercially available thermoplastic polymer (poly(2,6-dimethyl-1,4-phenylene) oxide, PPO), nanoporous-crystalline (NC) polymer films with a surface area (SA) higher than 600 m² g–¹ and with exceptionally fast organic pollutant uptakes are presented. Preparation procedures require fast crystallizations of amorphous films, as induced by high uptakes of nonvolatile guest molecules (typically in the range 70–90 wt %), followed by guest exchange with a volatile guest. The high SA of these NC PPO films is associated with a nanofibrillar morphology, analogous to those observed in physically cross-linked PPO aerogels. Organic pollutant diffusivities for high-SA NC PPO films are much higher than for other high-diffusivity PPO films, like for example those exhibiting NC phases with chain axes (and hence crystalline channels) being preferentially perpendicular to the film plane. Much higher diffusivities are observed both for guest sorption from vapor phase and from diluted PPO aqueous solutions and for guest desorption. Surprisingly, kinetics of guest uptakes from high-SA NC PPO films are even faster than for NC PPO aerogels and then much faster when referred to volume of the sorbent material. Because of their extremely fast kinetics of pollutant uptakes, associated with high thermal and mechanical stability, these new high-SA NC PPO films are expected to find many applications, mainly in pollutant remediation and molecular sensors.

    Abstract Delta (δ) and epsilon (ε) co-crystalline forms of syndiotactic polystyrene with a carboxylic acid guest were obtained by sorption of liquid hexanoic acid in syndiotactic polystyrene films exhibiting delta and epsilon nanoporous-crystalline forms. The characterization study is facilitated by axially stretched syndiotactic polystyrene films, used both for polarized FTIR spectra and for WAXD fiber patterns. Particularly informative are two carbonyl-stretching FTIR peaks, attributed to monomeric and dimeric hexanoic acid. The dichroism of these carbonyl peaks indicates that both delta and epsilon phases are able to include hexanoic acid as isolated guest molecules, while only the epsilon phase is also able to include dimeric hexanoic acid molecules in its crystalline channels. The inclusion of both isolated and dimeric hexanoic acid species in the epsilon form crystalline channels produces extremely fast hexanoic acid uptakes by syndiotactic polystyrene epsilon form films.
