Molecular and cellular determinants of L-Dopa-induced dyskinesia in Parkinson's Disease.

Treatment with L-3,4-dihydroxyphenylalanine (L-Dopa) compensates for decreased striatal dopamine (DA) levels and reduces Parkinson's disease (PD) symptoms. However, during disease progression, L-Dopa-induced dyskinesia (LID) develops virtually in all PD patients, making the control of PD symptoms difficult. Thus, understanding the mechanisms underlying LID and the control of these motor abnormalities is a major issue in the care of PD patients.

Combination of electro-oxidation and biological processes for lindane landfill leachate treatment: simultaneous degradation of contaminants and biological reduction of electro-generated chloride-derived by-products.

Real lindane landfill leachate (HCH-LL) is characterised by high chlorinated organic compounds concentrations (primarily hexachlorocyclohexane (HCH) isomers and degradation products generated during more than 40 years of ageing), posing environmental and human health risks. In this work, the co-treatment of real HCH-LL (pre-treated via electro-oxidation (EO)) and urban wastewater using an activated sludge process operated in an anoxic/oxic sequencing batch (A/O-SBR) mode was investigated. EO tests were conducted employing either a boron-doped diamond (BDD) anode or a dimensionally stable anode (DSA), resulting in effective HCH isomers removal (>93 % after 20 Ah/L).

Pulmonary embolism: incidence and outcomes in a twelve-year historical series, in Tuscany - Italy (2010-2021).

Background: Pulmonary embolism poses a global health concern. Administrative databases serve as valuable sources for broad epidemiological studies on the prevalence and incidence of major diagnoses or diseases. The primary scope is to provide up-to-date insights into Pulmonary Embolism incidence trends, examining shifts in management and outcomes.

Omega-3 polyunsaturated fatty acids and pulmonary arterial hypertension: Insights and perspectives.

Pulmonary arterial hypertension (PAH) is a rare and progressive disorder that affects the pulmonary vasculature. Although recent developments in pharmacotherapy have extended the life expectancy of PAH patients, their 5-year survival remains unacceptably low, underscoring the need for multitarget and more comprehensive approaches to managing the disease. This should incorporate not only medical, but also lifestyle interventions, including dietary changes and the use of nutraceutical support.

Physical activity habits prevent psychological distress in female academic students: The multiple mediating role of physical and psychosocial parameters.

Background: Psychological distress is recognised as the most common mental health difficulty in emerging adult (18-to-24-year-old) female academic students. This study aimed to test a novel model positing physical activity habits as a protective factor for psychological distress through the mediating role of physical and psychological parameters. Adherence to the Mediterranean diet and self-reported physical health status were included as physical parameters.

Urban wastewater disinfection by iron chelates mediated solar photo-Fenton: Effects on seven pathogens and antibiotic resistance transfer potential.

The effects of solar photo-Fenton (SPF) process mediated by the iron chelate Fe imminodisuccinic acid (Fe:IDS) on both the inactivation of seven relevant pathogens and the potential for antibiotic resistance transfer (degradation of antibiotic resistance genes (ARGs) and after treatment regrowth), in real secondary treated urban wastewater, were investigated for the first time. A comparison with results obtained by sunlight/HO process and Fe ethylenediaminedisuccinic acid (Fe:EDDS) SPF was also carried out. ARGs were quantified by polymerase chain reaction (PCR) in samples before and after (3 h) the treatment.

Epigenetic Mechanisms in Vascular Inflammation: Modulation of Endothelial Adhesion Molecules and Endothelium-Leukocyte Adhesion.

The endothelium, an essential component of the vascular system, plays a critical role in the inflammatory response. Under pro-inflammatory stimuli, endothelial cells undergo activation and dysfunction, leading to the release of inflammatory mediators and upregulation of cell adhesion molecules. These changes facilitate the adhesion, rolling, and transmigration of leukocytes into the subendothelial space.

Progress in Regenerative Medicine: Exploring Autologous Platelet Concentrates and Their Clinical Applications.

The goal of regenerative medicine is to achieve tissue regeneration. In the past, commonly used techniques included autologous or allogeneic transplantation and stem cell therapy, which have limitations, such as a lack of donor sites in the case of autologous transplantation and the invasiveness of stem cell harvesting. In recent years, research has, therefore, focused on new and less invasive strategies to achieve tissue regeneration.

Astrocyte Responses Influence Local Effects of Whole-Brain Magnetic Stimulation in Parkinsonian Rats.

Background: Excessive glutamatergic transmission in the striatum is implicated in Parkinson's disease (PD) progression. Astrocytes maintain glutamate homeostasis, protecting from excitotoxicity through the glutamate-aspartate transporter (GLAST), whose alterations have been reported in PD. Noninvasive brain stimulation using intermittent theta-burst stimulation (iTBS) acts on striatal neurons and glia, inducing neuromodulatory effects and functional recovery in experimental parkinsonism.

Exploring the significance of epicardial adipose tissue in aortic valve stenosis and left ventricular remodeling: Unveiling novel therapeutic and prognostic markers of disease.

Aortic stenosis (AS) is a dynamic degenerative process that shares many pathophysiological features with atherogenesis, from initial proinflammatory calcification and focal thickening of the valve leaflets to obstruction of left ventricular outflow due to superimposed of severe calcification and immobilization of the valve leaflets. As the prevalence increases with age, AS is expected to become one of the most common heart diseases worldwide. In both obese and nonobese patients, persistent thickening of epicardial adipose tissue (EAT) is associated with a shift in its normal metabolic functions toward a dysmetabolic and proatherogenic phenotype that may impair the physiology of adjacent coronary arteries and promote the occurrence of coronary atherosclerosis.

Tanshinone IIA and Cryptotanshinone Counteract Inflammation by Regulating Gene and miRNA Expression in Human SGBS Adipocytes.

Inflammation of the adipose tissue contributes to the onset and progression of several chronic obesity-related diseases. The two most important lipophilic diterpenoid compounds found in the root of Bunge (also called Danshen), tanshinone IIA (TIIA) and cryptotanshinone (CRY), have many favorable pharmacological effects. However, their roles in obesity-associated adipocyte inflammation and related sub-networks have not been fully elucidated.

[Arrhythmias in adult congenital heart disease at the emergency department: ANMCO Tuscany clinical pathway].

Arrhythmias are a common complication in the adult population with congenital heart disease (ACHD). Arrhythmias often lead to hemodynamic instability and, on the other hand, may be a marker of hemodynamic impairment in ACHD patients, both in natural history and after cardiac surgery. Treatment requires knowledge of basic anatomy and any previous cardiac surgery; the availability of patient's health records, if possible, is therefore crucial for therapeutic choices.

Intensive exercise ameliorates motor and cognitive symptoms in experimental Parkinson's disease restoring striatal synaptic plasticity.

Intensive physical activity improves motor functions in patients with Parkinson's disease (PD) at early stages. However, the mechanisms underlying the beneficial effects of exercise on PD-associated neuronal alterations have not been fully clarified yet. Here, we tested the hypothesis that an intensive treadmill training program rescues alterations in striatal plasticity and early motor and cognitive deficits in rats receiving an intrastriatal injection of alpha-synuclein (α-syn) preformed fibrils.

Association between Mediterranean lifestyle and perception of well-being and distress in a sample population of university Italian students.

We investigated the extent to which adherence to the Mediterranean diet (MD) in combination with Mediterranean lifestyle factors influenced students' perceptions of subjective well-being (SWB) and distress. 939 undergraduates completed a survey to assess sociodemographic and lifestyle characteristics, including adherence to the MD, depression, anxiety, stress, and SWB. Data were analysed with correlation, logistic, and multiple linear regression models.

Hydroxyapatite-Silicon Scaffold Promotes Osteogenic Differentiation of CGF Primary Cells.

The application of scaffolding materials together with stem cell technologies plays a key role in tissue regeneration. Therefore, in this study, CGF (concentrated growth factor), which represents an autologous and biocompatible blood-derived product rich in growth factors and multipotent stem cells, was used together with a hydroxyapatite and silicon (HA-Si) scaffold, which represents a very interesting material in the field of bone reconstructive surgery. The aim of this work was to evaluate the potential osteogenic differentiation of CGF primary cells induced by HA-Si scaffolds.

Improving organic matter and nutrients removal and minimizing sludge production in landfill leachate pre-treatment by Fenton process through a comprehensive response surface methodology approach.

Landfill leachate (LL) represents a very complex effluent difficult to treat and to manage which usually requires a chemical pre-treatment. In this study, response surface methodology (RSM) was used to identify the optimum operating conditions of the Fenton process as a pre-treatment of LL in order to reduce the high organic content and simultaneously optimize the BOD:TN:TP ratio. The dosages of Fenton process reagents, namely Fe and HO, were used as variables for the implementation of RSM.

In Vitro Anti-Inflammatory and Vasculoprotective Effects of Red Cell Extract from the Black Sea Urchin .

Sea urchins have emerged as an important source of bioactive compounds with anti-inflammatory and antioxidant properties relevant to human health. Since inflammation is a crucial pathogenic process in the development and progression of atherosclerosis, we here assessed the potential anti-inflammatory and vasculoprotective effects of coelomic red-cell methanolic extract of the black sea urchin in an in vitro model of endothelial cell dysfunction. Human microvascular endothelial cells (HMEC-1) were pretreated with red-cell extract (10 and 100 μg/mL) before exposure to the pro-inflammatory cytokine tumor necrosis factor (TNF)-α.

Chelating agents supported solar photo-Fenton and sunlight/HO processes for pharmaceuticals removal and resistant pathogens inactivation in quaternary treatment for urban wastewater reuse.

In this work, Fe-iminodisuccinic acid (Fe:IDS) based solar photo Fenton (SPF), an Italian patented method, was investigated in quaternary treatment of real urban wastewater and compared to Fe-ethylenediamine-N,N'-disuccinic acid (Fe:EDDS) for the first time. Three pharmaceuticals (PCs) (sulfamethoxazole, carbamazepine and trimethoprim) and four pathogens (Escherichia coli, somatic and F-plus coliphages, Clostridium perfringens, consistently with the new EU regulation for wastewater reuse (2020/741)), were chosen as target pollutants. SPF with Fe:EDDS was more effective in PCs removal (80%, 10 kJ L) than the SPF with Fe:IDS (58%), possibly due to the higher capability of generating hydroxyl radicals.

[Pulmonary hypertension clinical pathway: ANMCO Tuscany Board model].

Pulmonary hypertension (PH) is defined by a mean pulmonary artery pressure >20 mmHg at rest during right heart catheterization. PH prevalence is about 1% of the global population. The PH clinical classification includes five groups: pulmonary arterial hypertension, PH associated with left heart disease, PH associated with lung disease, PH associated with pulmonary artery obstructions, PH with unclear and/or multifactorial mechanisms.

Development of L-Lysine-Loaded PLGA Microparticles as a Controlled Release System for Angiogenesis Enhancement.

Vascularization is a highly conserved and considerably complex and precise process that is finely driven by endogenous regulatory processes at the tissue and systemic levels. However, it can reveal itself to be slow and inadequate for tissue repair and regeneration consequent to severe lesions/damages. Several biomaterial-based strategies were developed to support and enhance vasculogenesis by supplying pro-angiogenic agents.

Landfill leachate treatment by a combination of a multiple plant hybrid constructed wetland system with a solar photoFenton process in a raceway pond reactor.

The sustainable and green treatment of landfill leachate (LL), produced by municipal solid waste, represents one of the most relevant challenges in the integrated waste management systems. Accordingly, in this work a green solution was investigated by coupling an innovative hybrid constructed wetland (HCW) to a solar photo-Fenton (SPF) process. A multiple layers HCW pilot plant including different medium substrates (sand, solid compost and carriers) and plant species (Phragmites australis, Arundo donax and A.

Co-treatment of landfill leachate with urban wastewater by chemical, physical and biological processes: Fenton oxidation preserves autochthonous bacterial community in the activated sludge process.

The impact of Fenton oxidation (FO) and Air stripping (AS) pre-treatments on the bacterial community of a biological activated sludge (B-AS) process for the co-treatment of mature landfill leachate (MLL) and urban wastewater (UWW) was assessed. In this work high-throughput sequencing was used to identify changes in the composition of the bacterial communities when exposed to different landfill leachate's pre-treatments. The combination of FO and AS to increase biodegradability (BOD/COD) and reduce ammonia concentration (NH) respectively, allowed to successfully operate the B-AS and effectively treat MLL.
