Abstract
Vigna unguiculata L. Walp. is an African crop spread worldwide mainly for pulses production. Despite being a neglected and under-utilized food, cowpea leaves are a rich source of phytochemicals and micronutrients. The aim of the work is to characterize the phytochemical composition of cowpea leaves by an optimized ultrasound-assisted extraction (USAE) and to compare raw and boiled leaves. A three-level factorial design (Box-Behnken) was employed for the optimization of the USAE considering three different parameters (% ethanol, drug-to-solvent ratio, and number of cycles). The optimized extracts were characterized by LC/MS/MS. Finally, leaves were boiled at 100 °C for 30 min to simulate traditional cooking procedures and compared to raw leaves. The best extraction condition was EtOH/H2 O 1 : 2 v/v, drug to solvent ratio 1 : 47 w/v, and 3 extraction cycles. The phytochemicals identified mainly belong to the family of phenolic acids, flavonoids, terpenoids, and alkaloids. Boiled leaves revealed a significant loss of most phytochemicals and a net decrease of their antioxidant activity compared to the raw ones. The results highlight the potential nutraceutical value of cowpea leaves whilst the impoverishment triggered by traditional consumer habits pushes the need to evaluate alternative cooking procedures helpful in the maintenance of their phytochemical properties.

Abstract
Time-resolved optical spectroscopy represents an effective non-invasive approach to investigate the interplay of different degrees of freedom, which plays a key role in the development of novel functional materials. Here, we present magneto-acoustic data on Ni thin films on SiO2 as obtained by a versatile pump-probe setup that combines transient grating spectroscopy with time-resolved magnetic polarimetry. The possibility to easily switch from a pulsed to continuous wave probe allows probing of acoustic and magnetization dynamics on a broad time scale, in both transmission and reflection geometry.

Abstract
The research into the pathophysiology of atherosclerosis has considerably increased our understanding of the disease complexity, but still many questions remain unanswered, both mechanistically and pharmacologically. Here, we provided evidence that the pro-oxidant enzyme Prenylcysteine Oxidase 1 (PCYOX1), in the human atherosclerotic lesions, is both synthesized locally and transported within the subintimal space by proatherogenic lipoproteins accumulating in the arterial wall during atherogenesis. Further, Pcyox1 deficiency in Apoe-/- mice retards atheroprogression, is associated with decreased features of lesion vulnerability and lower levels of lipid peroxidation, reduces plasma lipid levels and inflammation. PCYOX1 silencing in vitro affects the cellular proteome by influencing multiple functions related to inflammation, oxidative stress, and platelet adhesion. Collectively, these findings identify the pro-oxidant enzyme PCYOX1 as an emerging player in atherogenesis and, therefore, understanding the biology and mechanisms of all functions of this unique enzyme is likely to provide additional therapeutic opportunities in addressing atherosclerosis.

Abstract
PURPOSE Less invasive direct anterior approach (DAA) and dual mobility cup (DMC) are increasingly adopted in practice over the last decade. Their use aims to reduce, as much as possible, soft tissue dissection and dislocation rate. This study aims to present a novel surgical technique to reduce a DMC prosthesis during a DAA easily. METHODS A mildly modified version of the direct anterior approach is proposed. When leg lengths, stability, impingement, and tension have been checked, the trial stem is disassembled in situ, dislocated, and removed, leaving the space to exchange the trial double mobility head with the definitive one. When the definitive stem is inserted, the surgeon guides and helps the assistant to match the trunnion in the double mobility head. As soon as the components are matched, the traction is released, and the unit is impacted by an alternation of axial traction and release. RESULTS Of 164 patients who underwent primary total hip arthroplasty (December 2016-May 2017) by a single surgeon, a double mobility cup through DAA and the "head-first" technique was performed in 26 patients (15.8%). The mean operative time was 130 min (85-220 min; SD 34.28). No significant complications occurred during the mean follow-up of 23.6 months. CONCLUSIONS Specific difficulties can be anticipated when pairing dual mobility cup and direct anterior approach. The "head-first" technique is a useful technique in reducing the possible difficulties related to the reduction of double mobility cup through a less invasive direct anterior approach.

Abstract
INTRODUCTION Defects of the Achilles tendon region represent a challenge for reconstructive surgeons. Several options are available but there is still no reconstructive ladder for this specific and tricky area. An up-to-date reconstructive ladder according to local and general conditions is proposed based on our multicentre experience and an extensive review of the English literature on PubMed. MATERIALS AND METHODS An extensive review of the English literature was performed on PubMed using the following key-words: "Achilles region", "heel", "soft-tissue reconstruction", "flaps", "grafts" and "dermal substitutes". RESULTS A total of 69 complete papers were selected, covering the last thirty years' literature. Although most of the studies were based on limited case-series, local and general conditions were always reported. A comprehensive reconstructive ladder of all the available reconstructive techniques for the Achilles region has been created based on our personal multicentre experience and the results of the literature review. CONCLUSIONS The reconstructive ladder is a concept that is still a mainstay in plastic surgery and guides decisions in the repair strategy for soft tissue defects. The optimal solution, according to the experience of the surgeon and the wishes of the patient, is the one that implies less sacrifice of the donor site. Perforator flaps should be the first-line option for small-to-moderate defects; the distally-based sural flap is the most reported for moderate-to-large defects of the Achilles region, and free flaps should be reserved mainly for complex and wide reconstructions.

Abstract
This data article is referred to the research article entitled Human monocyte-derived macrophages are heterogeneous: proteomic profile of different phenotypes by Eligini et al. Eligini S., Brioschi M., Fiorelli S., Tremoli E., Banfi C., Colli S. Human monocyte-derived macrophages are heterogeneous: proteomic profile of different phenotypes. J. Proteomics 124, 2015, 112-123. Macrophages obtained in vitro from blood monocytes are largely used as surrogate model of tissue macrophages that are heterogeneous and not easy to obtain and handle. Under spontaneous differentiation in vitro, monocyte-derived macrophages (MDMs) display two dominant subsets (round and spindle) that show different transcriptional, antigenic, and functional profiles mimicking, at least in part, the heterogeneity of tissue macrophages. This article reports the nano-LC-MSE analysis of the proteome of round and spindle MDMs allowing a deeper comprehension of macrophage heterogeneity.

Abstract
BACKGROUND Protease-activated receptors (PARs) are G-protein-coupled receptors that function in hemostasis and thrombosis, as well as in the inflammatory and proliferative responses triggered by tissue injury. We have previously shown that PAR1 or PAR2 occupancy by specific PAR-agonist peptides (PAR-APs) induces tissue factor (TF) expression in human umbilical vein endothelial cells (HUVECs), where TF regulation by PAR1 (but not by PAR2) requires intact endothelial caveolin-enriched membrane microdomains in which PAR1 and caveolin-1 associate. OBJECTIVES The aim of this study was to determine the effects of cholesterol-lowering agents (statins) and cholesterol-loading lipoprotein on PAR1-AP-mediated and PAR2-AP-mediated TF induction in HUVECs. RESULTS Statins completely prevented TF induction by PAR-APs in an isoprenoid-independent manner, induced the delocalization of PAR1 from caveolin-enriched membrane microdomains without affecting PAR1 mRNA, and decreased PAR2 mRNA and protein levels. Statins also prevented PAR-AP-mediated extracellular signal-related kinase 1/2 activation, which is crucial for TF induction. The redistribution of PAR1 is accompanied by the relocation of the membrane microdomain-associated G-protein α, caveolin-1, and Src, which we previously showed to play a key role in signal transduction and TF induction. Conversely, cholesterol loading potently amplified PAR1-AP-induced TF, probably as a result of the increased abundance of PAR1 and the Src and G-protein α signaling molecules in the caveolin-1-enriched fraction, without affecting PAR1 mRNA. CONCLUSIONS As PARs have important functions in hemostasis, cancer, thrombosis, and inflammatory processes, our findings that statins prevent TF induction by PAR-APs altering the membrane localization of PAR1 and the expression of PAR2 suggest that they may provide health benefits other than reducing atherosclerosis.

Abstract
Three elderly patients with, respectively: mild cognitive impairment, severe and progressive neurologic involvement, and focal neurologic deficit, were observed. MRI showed multiple areas of white matter edema, at times partially involving the cortex, in the first two patients, and a single area in the third. Treatment with steroids determined the disappearance of the lesions and clinical amelioration. The key to the diagnosis of cerebral amyloid angiopathy-related inflammation (CAA-ri) was the demonstration, with appropriate MRI sequences, of microbleeds consistent with cerebral amyloid angiopathy (CAA). This diagnosis was supported by genetic analysis of APOE with demonstration of ε4/ε4 genotype, found in about 80% of CAA patients who develop inflammatory changes. In the appropriate clinical setting, MRI demonstration of microbleeds supported by results of genetic analysis of APOE may strongly support the diagnosis of CAA-ri thus avoiding cerebral biopsy.

Abstract
PURPOSE Histone Deacetylase Inhibitors (DI) ameliorates dystrophic muscle regeneration restoring muscular strength in the mdx mouse model of Duchenne muscular dystrophy (DMD). The further development of these compounds as drugs for DMD treatment is currently hampered by the lack of knowledge about DIs effect in large dystrophic animal models and that of suitable biomarkers to monitor their efficacy. EXPERIMENTAL DESIGN In this study we applied proteomic analysis to identify differentially expressed proteins present in plasma samples from mdx mice treated with the Suberoylanilide hydroxamic acid (SAHA) and relative normal controls (WT). RESULTS Several differentially expressed proteins were identified between untreated wild type and mdx mice. Among these, fibrinogen, epidermal growth factor 2 receptor, major urinary protein and glutathione peroxidase 3 (GPX3) were constitutively up-regulated in mdx, while complement C3, complement C6, gelsolin, leukaemia inhibitory factor receptor (LIFr), and alpha 2 macroglobulin were down-regulated compared to WT mice. SAHA determined the normalization of LIFr and GPX3 protein level while apoliprotein E was de novo up-regulated in comparison to vehicle-treated mdx mice. CONCLUSIONS AND CLINICAL RELEVANCE Collectively, these data unravel potential serological disease biomarkers of mdx that could be useful to monitor muscular dystrophy response to DI treatment.

Abstract
BACKGROUND Protease-activated receptors (PARs) comprise a family of G-protein-coupled receptors with a unique proteolytic activation mechanism. PARs regulate a broad range of cellular functions and are involved in the pathogenesis of inflammatory disorders. Moreover, PAR1 and PAR2 activation in the endothelium shifts it toward a prothrombotic condition. OBJECTIVES To assess the relevance of intracellular reactive oxygen species (ROS) in the signaling events underlying tissue factor (TF) expression elicited by PAR1 and PAR2 occupancy in endothelial cells, and to investigate their source. METHODS Human umbilical vein endothelial cells (HUVEC) were exposed to specific PAR1 and PAR2 agonist peptides. TF expression was determined by real-time reverse transcription polymerase chain reaction analysis and measurement of procoagulant activity. ROS generation was determined by a fluorometric assay after cell loading with 2'-7'-dichlorofluorescein diacetate. RESULTS ROS generated by the mitochondrial chain, mostly from complex III, provide a pathway through which PAR1 and PAR2 occupancy induces TF. Other sources of ROS do not participate in TF induction. Activation of both ERK1/2 and p38 MAPK is critical for mitochondrial ROS generation. In addition to these pathways shared by the two PARs, mechanisms downstream from PAR1 and PAR2 activation, different for the two receptors, also induced TF. A module that sensitively regulates PAR1 signaling and ultimately involves NF-kappaB activation has been identified. CONCLUSIONS Our data identify ROS originating in mitochondria as key mediators of the signaling pathways triggered by PAR1 and PAR2 engagement in endothelial cells and show that downstream from receptor activation occur cascades that are mechanistically coupled to procoagulant activity.

Abstract
BACKGROUND Protease-activated receptors (PARs) comprise a family of G-protein-coupled receptors with a unique mechanism of proteolytic activation. PARs regulate a broad range of cellular functions and are active in the pathogenesis of disorders characterized by chronic inflammation or activation of the coagulation cascade. Signaling through PAR1 and PAR2 shifts the endothelium towards a prothrombotic phenotype, thereby exacerbating the initial pathophysiologic condition. OBJECTIVES This study aimed to analyze the localization of PARs in the cell membrane and how their compartmentalization affects tissue factor (TF) in human endothelial cells. METHODS TF expression was determined by quantitative real-time polymerase chain reaction analysis and by activity assays. The interaction of PARs with caveolin was investigated through: (i) caveolin-1 gene knockdown performed by transfection with specific small interfering RNA (siRNA); (ii) caveolin-enriched membrane microdomain disruption; and (iii) coimmunoprecipitation assay. RESULTS We have shown that PAR1, but not PAR2, is present in endothelial caveolin-enriched membrane microdomains, where it is bound to caveolin-1, and that these structures must be intact if PAR1-induced signaling is to increase TF activity. Cholesterol depletion of endothelial cells by cholesterol-sequestering agents caused the PAR1 to relocate to high-density membranes, and impaired the induction of TF (P < 0.01) without affecting the PAR2-mediated procoagulant effect. In addition, siRNA directed against caveolin-1 inhibited TF activation by PAR1 (P < 0.01 and P < 0.01, respectively). CONCLUSIONS PAR1 localization in the caveolin-enriched membrane microdomain, bound to caveolin-1, represents a crucial requirement for TF induction in endothelial cells.

Abstract
AIM This study was aimed at assessing the clinical performances of a NaI(Tl) crystal 3D PET scanner, C-PET (ADAC-UGM), using a multi-ring 2D BGO PET scanner (multi-ring PET), as a reference. METHODS Thirty-seven oncological patients were studied in sequence with multi-ring PET and C-PET, within 30 days of a CT study. In order to assess the behaviour of C-PET in relation to acquisition count rate, patients were divided into 3 groups according to the count rate at the time of the C-PET scan acquisition. Group A (n=21): 3000-5000 kcounts/sec (recommended count rate range); Group B (n=8): <3000 Kcounts/sec and Group C (n=8): >5000 Kcounts/sec. RESULTS The number of lesions detected by multi-ring PET and C-PET, classified according to size, was compared. For Group A and Group B there was a good agreement between C-PET and multi-ring PET in terms of lesion detectability (relative sensitivity: 99.9% and 96.0%, respectively), while for Group C the relative sensitivity of C-PET was 61.9%. CONCLUSION Optimal performances of the C-PET scanner can thus be obtained at a count rate within or below the recommended range. Despite a lower lesion/background contrast resulting from a high scatter and random noise, the sensitivity of C-PET in detecting hypermetabolic lesions is comparable to that of multi-ring PET. These findings are discussed in relation to the physical performance of the two scanners and particularly in relation to the 3D vs 2D acquisition modality.

Abstract
PURPOSE We compared [11C]choline-positron emission tomography (PET) with [18F]fluorodeoxyglucose-PET for re-staging prostate cancer in a group of 100 patients. MATERIALS AND METHODS A total of 100 consecutive patients referred for whole body [18F]fluorodeoxyglucose-PET for clinical prostate re-staging after radical treatment for prostate cancer were retrospectively included in the study. Mean prostate specific antigen (PSA) was 6.57 ng./ml. In all cases [11C]choline-PET was also performed. PET studies were done with a multiring device 5 minutes after intravenous injection of approximately 370 MBq. [11C]choline and 60 minutes after injection of approximately 370 MBq. [18F]fluorodeoxyglucose. PET findings were compared with those obtained with different conventional imaging and with PSA assessed at the time of PET and 1 year later. RESULTS Areas of abnormal focal increases were noted in 47% of patients on [11C]choline-PET and in 27% on [18F]fluorodeoxyglucose-PET. Of the 100 patients 49 had positive conventional imaging findings. All except 14 [11C]choline-PET findings were concordant with conventional imaging, including 6 negative and 8 positive conventional imaging results. All except 1 [11C]choline-PET negative cases also had negative conventional imaging after 1 year. PSA at 1 year remained stable or decreased in 80% and 62% of [11C]choline-PET negative and positive cases, respectively. CONCLUSIONS [11C]choline-PET seems to be useful for re-staging prostatectomy cases with increasing serum PSA levels. It is superior to [18F]fluorodeoxyglucose-PET and complementary to conventional imaging but with the advantage of staging disease at a single step.
