- Abstract
The aim of this paper is to analyse the role of wheat quality in the formation of wheat prices in the early modern period, adopting eighteenth-century northern Italy as a case study. Wheat prices have been widely used by economic historians to calculate living standards, determine the degree of market integration, and date famines. Rarely, however, have economic historians focused on how wheat prices were determined. By looking at the wheat supply chain, we will try to make more visible the extent to which wheat quality was crucial in determining the value of wheat and, as a consequence, the final price of grain.

- Abstract
This study estimates the cost of living in three cities – Florence, Bologna and Milan – in eighteenth-century northern Italy. Although they do not allow an understanding of the differences between social groups or seasonal consumption patterns, the calculation of living costs and the implied modelling have a twofold aim. First, they allow the calculation of real wages, which are obtained by dividing nominal wages by the cost of a consumption basket; therefore, broadly, they allow the Italian case to be put into great debates of economic history, such as the one on the Little Divergence between northern and southern Europe at the end of the early modern period. In this regard, we will show that the existing calculations used for this purpose have many criticalities, and we will solve them. Second, determining the cost of consumption baskets allows us to observe the role played by urban public institutions in mediating between the market and consumers, with relevant effects on price trends and, therefore, on the purchasing power of the urban population.

This article explores the reasons why seasonal patterns in historical grain prices series often deviated from the expected pattern of low prices post-harvest and gradually rising prices until the next harvest. We analyse eighteenth-century Flemish and northern Italian grain prices to focus on the role of storage technologies, alternative seasonal patterns in supply and demand, and particularly quality variation. We argue that quality was not consistent throughout the harvest year because (1) grain quality improved in store and (2) grain producers selected different qualities for sale at different times of the year. Consequently, seasonal patterns in grain prices were affected by (1) the quality of stored grain gradually improving, (2) the balance of old and new grain available for sale and (3) the dumping in the market of poor-quality old grain, not ordinarily sold, when a new, successful harvest was in sight. These factors mattered, in addition to supply-and-demand effects that varied between cereals and regions, depending on storage technologies and buyers’ preferences.

- Abstract
In this study, we report the experimental findings of a multi-methodological and comparative investigation of a natural (from the Wah Wah Mountains of Beaver County, Utah) and three synthetic (hydrothermally grown) gem-quality red beryls by means of: gemmological standard testing, laser ablation inductively coupled mass spectroscopy, infrared and Raman spectroscopy, ultraviolet–visible–near infrared absorption spectroscopy, and single-crystal X-ray diffraction. Gemmological, crystallo-chemical, and spectroscopic features of the natural and synthetic stones enabled us to unveil the causes of their color (from red, to purplish-red, or orange-red) and how different and complementary techniques can be efficiently used to discriminate between natural and synthetic materials, based on non-destructive, micro-destructive, and destructive techniques.

- Abstract
Agates from Yozgat province are appreciated on the gem market for their white and purple-blue banded colours. In this study, we present a detailed investigation aimed at the identification of the atomic and structural origin of this peculiar colouration of chalcedony. X-ray diffraction and Raman spectroscopy revealed the presence of fine grains of quartz and moganite with a preferential accumulation of the latter in the blue bands. Near-infrared diffuse absorption spectra show overtones of hydroxyls vibrations at 1425, 1900, and 2250 nm. In the visible, the broad absorption at about 500 nm, as well as its behaviour at low temperatures, is compatible with the optical activity of iron impurities in quartz matrices, such as that observed in amethysts. Peak intensities and shapes are very similar for spectra collected in blue and white bands. Accordingly, trace-element composition from laser ablation inductively coupled mass spectrometry confirmed that the two regions have similar Fe content. The perceived changes in band colours are indeed originated by differences in microstructural arrangement and size of the grains visualised through scanning electron microscopy. White and blue stripes have grains of about 5 µm and 300 nm in size, respectively, resulting in an accentuated scattering component for the white bands. Therefore, the unique purple-blue shades typical of Yozgat agates are a combination of iron-related colour centres and scattering effect.

SECS-P/12 - STORIA ECONOMICA ,Brand Entrepreneur, Business History - Abstract
Il tema del globale nella sua pluralità di significati è divenuto l’oggetto dei molteplici approcci storiografici che ne hanno esaminato le radici costitutive. Tra queste, rilevanza crescente ha assunto la storia economica e ancor più quella d’impresa nel provare quanto sia stato l’operato degli agenti nel costruire i legami tra le economie e le società nei cruciali decenni a cavallo tra XIX e XX secolo. Il problematico utilizzo di indicatori quantitativi, quali gli investimenti diretti all’estero (FDI) e /o il “portfolio investment”, hanno contribuito a delinearne il sentiero nel tempo, lungo il quale si sono declinate le cause mutanti e gli ostacoli frenanti, mentre l’attenzione crescente agli agenti ha svelato quanto taluni mercati siano stati a lungo dominati da un numero di attori assai ristretto, tanto da sovrapporre settore e imprese per un numero crescente di beni, dalle materie prime ai beni coloniali e di largo consumo. Negli anni taluni brand divennero sinonimi stessi dei prodotti anche per brand italiani presentati e discussi nel volume.

- Abstract
The book investigates some aspects of the Italian economic development looking at some usually forgotten cases of international success: the small-medium enterprises specialized in “light” productions, such as food, beverages, and apparel. These firms have shown a peculiar ability to adapt, in order to cope with the instabilities of the international markets, modifying both their organization and their business strategies, elaborating an unusual entrepreneurial style, more attentive to the resources, constraints and vulnerabilities of the context.

- Abstract
During the last decades many studies have been carried out to investigate how point defects and aggregates respond and evolve in natural Type Ia diamonds as a result of treatments, and a number of underlying mechanisms have been identified and interpreted. However, the analysis of radiation-induced creation/ionization of defects, as well as their migration and aggregation in secondary defect structures, often requires experimental approaches which can hardly constitute a simple-to-use diagnostic tool for the identification of artificially treated diamonds. Here we disclose a novel simple indicator of artificial exposure of Type Ia diamonds to ionizing radiations and subsequent annealing. This indicator consists in narrow photoluminescence lines in the red region, between 681 and 725 nm, we recently found to result from vacancies trapped by interstitial carbon aggregates and platelets. Our results demonstrate that interstitial structures become sites of vacancy trapping – by thermal migration of radiation-induced vacancies – only when diamond undergoes treatments. We give the rigorous validation of the new spectroscopic probe of artificial treatments analysing photoluminescence and infrared absorption spectra of well-known H1b and H1c centres in a hundred samples. Importantly, the method is based on emission lines which do not require neither high photon-energy excitation nor cryogenic temperatures.

CARBON ,ZEBRA danio ,GROUP 14 elements ,EMBRYOS ,EMBRYOLOGY - Abstract
Carbon-based nanoparticles (CBNs) are largely distributed worldwide due to fossil fuel combustion and their presence in many consumer products. In addition to their proven toxicological effects in several biological models, attention in recent years has focussed on the role played by CBNs as Trojan-horse carriers for adsorbed environmental pollutants. This role has not been conclusively determined to date because CBNs can decrease the bioavailability of contaminants or represent an additional source of intake. Herein, we evaluated the intake, transport and distribution of one of the carbon-based powders, the so-called carbon nanopowder (CNPW), and benzo(α)pyrene, when administered alone and in co-exposure toDanio rerioembryos. Data obtained by means of advanced microscopic techniques illustrated that the “particle-specific” effect induced a modification in the accumulation of benzo(α)pyrene, which is forced to follow the distribution of the physical pollutant instead of its natural bioaccumulation. The combined results from functional proteomics and gene transcription analysis highlighted the different biochemical pathways involved in the action of the two different contaminants administered alone and when bound together. In particular, we observed a clear change in several proteins involved in the homeostatic response to hypoxia only after exposure to the CNPW or co-exposure to the mixture, whereas exposure to benzo(α)pyrene alone mainly modified structural proteins. The entire dataset suggested a Trojan-horse mechanism involved in the biological impacts onDanio rerioembryos especially due to different bioaccumulation pathways and cellular targets.

Missed nursing care (MNC), such as nursing care omitted or delayed, has not been measured in the Italian context where several cost containment interventions affect the care offered in medical units. The aim of the study is to identify the amount, type, and reasons for MNC in the Italian medical care setting and to explore the factors that affect the occurrence of MNC. A 3-month longitudinal survey was carried out followed by a cross-sectional study design in 12 north eastern acute medical units. A total of 314 nursing staff members were involved. Multivariate logistic regression was performed to identify the predictors of MNC. Patient ambulation (91.4 %), turning the patient every 2 h (74.2 %), and right timing in administering medications (64.6 %) were the most perceived MNC. Among the most frequent reasons were the unexpected rise in patient volume or critical conditions (95.2 %), inadequate numbers of staff (94.9 %), and large numbers of admissions/discharges (93.3 %). The R (2) 33.2 % of the variance in MNC were explained by a full-time position (OR 4.743, 95 % CI 1.146-19.629), communication tensions between Registered Nurses and Nurses' Aides (OR 1.601, 95 % CI 1.020-2.515), the amount of experience in medical unit (OR 1.564, 95 % CI 1.021-2.397), and the amount of daily care offered by Nurses' Aides (1.039, 95 % CI 1.011-1.067). A substantial amount of basic and clinically relevant nursing interventions was perceived to be missed, and this may lead to an increase in negative outcomes for patients admitted to a medical unit. Appropriate standards of nursing care should be adopted urgently in medical units aiming to protect frail patients.

- Abstract
Background and Objectives : Irritable bowel syndrome (IBS) is an invasive and potentially disabling syndrome characterized by a multitude of symptoms capable of reducing the quality of life of patients. Among the most disabling symptoms of IBS is certainly physical pain, which manifests itself mainly at the abdominal level but can also appear in other areas of the body, particularly in the form of chronic low-back pain (CLBP). Among the non-invasive methods of treating organ-specific pathologies and organ-related musculoskeletal problems, the use of Bioresonance Therapy (BT)-based on the administration of self-modulating Extremely Low-Frequency Electromagnetic Fields, capable of determining a rebalance of bio-electrical and metabolic activity in the presence of various functional alterations-is currently gaining acceptance. Therefore, we decided to monitor results obtained from patients suffering from IBS and CLBP subjected to a cycle of treatments with BT. Materials and Methods : We monitored 20 patients (12 women and 8 men, average age of 51 years) suffering from CLBP and other visceral symptoms related to IBS. Patients were monitored through the use of the Bristol Stool Form Scale (BSFS), the Fecal Calprotectin test and the Short-Form Health Survey 36 (SF-36), collected before (T0) and after (T1) the execution of the cycle of treatments. They undertook a treatment protocol consisting of eight sessions of BT carried out over about a month. Results : At the end of the treatments with BT, it was possible to observe a general and significant improvement in all the parameters observed, as well as a close inversely proportional correlation between the Calprotectin values detected and the quality of life experienced by the patients in relation to their perceived IBS symptoms. Conclusions : Overall, our pilot study would seem to suggest a potential beneficial effect of BT in modulating organic and musculoskeletal symptoms derived from IBS.

- Abstract
Background: The terminology of urinary incontinence (UI) and pelvic floor dysfunctions is complex. It affects quality of life and daily activities in personal, social, and professional fields. Managing UI without pharmacologic therapies is effective with a low risk of adverse effects and a large benefit for increasing continence rates. The aim of this preliminary retrospective observational study is to evaluate the effectiveness of the association between manual therapy and focused mechano-acoustic vibrations in women with nonspecific UI., Materials and Methods: A group of 15 incontinent women (mean age 59.5 ± 11.4), referred to the Physiotherapy Center, Rehabilitation and Re-education (Ce.Fi.R.R.), located at the University "Gabriele d'Annunzio" of Chieti-Pescara from January 2019 December 2021, were enrolled after medical examination. The women were evaluated at T0 (admission protocol), T1 (after 8 weeks), and T2 (after 12 weeks). All patients received the rehabilitation protocol twice a week for a total of 8 weeks (T1) and were reevaluated after 12 weeks (T2). Outcome measures were: the Pelvic Floor Disability Index, the Pelvic Floor Impact Questionnaire-7, and the MyotonPRO., Results: The analysis of MyotonPRO data showed no significant improvements in all parameters. The PFDI-20 and PFIQ-7 questionnaire results showed a significant reduction in scores between T0 and T2.Results over time of the ANOVA values confirming the significant differences in the PFDI-20 and PFIQ-7 questionnaire results but not in the MyotonPRO variables., Conclusions: Despite limitations and no significant results, this study demonstrated that the integration of manual and focused mechano-acoustic vibrations therapy improved the symptoms of UI and reduced its psychosocial impact. Further experience could be required to establish the place of this integrated approach in achieving long-term improvements in UI.

- Abstract
Background: There is need for improvement in effective pressure ulcers preventive strategies., Objective: To study whether a multi-layer silicone-adhesive polyurethane foam dressing shaped for the sacrum prevents PUs development in addition to standard PU preventive care for at-risk hospitalized patients., Design: Open-label, parallel group, multi-center randomized controlled trial., Participants and Setting: 709 in-hospital patients at risk for pressure ulcers from 25 medical, surgical, and intensive care units of 12 Italian hospitals., Methods: A multi-layer silicone-adhesive polyurethane foam was applied to the sacrum in addition to standard PUs preventive care in the intervention group. In the control group, standard preventive care alone, including systematic pressure ulcer risk assessment, skin assessment three times per day, routine positioning every 4 h, use of active support surface as appropriate, and incontinence skin care, was guaranteed. Primary outcome was incidence of sacral pressure ulcers of any stage at seven days from hospital admission. Secondary outcomes were incidence of sacral pressure ulcers ≥ II stage, number of days needed to PU development, number of skin adverse events due to the foam dressing, number of dressings used for each patient, number of withdrawing patients due to discomfort caused by the foam dressing. Participants were evaluated at baseline and at seven days., Results: In patients admitted to medical units, 15/113 controls and 4/118 in the intervention group developed sacral pressure ulcers (p = 0.010; absolute reduction 9.2%; NNT for benefit 11, 95% CI 6 to 44). In patients admitted to surgical units, 21/144 controls and 8/142 in the intervention group developed sacral pressure ulcers (p = 0.010; absolute reduction 8.9%; NNT for benefit 11 95% CI 6 to 49). Pressure ulcers incidence was not significantly different between the randomization arms (5.2% experimental vs 10.4% control, p = 0.141) in patients admitted to intensive care units. Overall, 46/358 (12.8%) controls and 17/351 (4.8%) in the intervention group developed sacral pressure ulcers (p<0.001; absolute reduction 8%; number needed to treat (NNT) for benefit 12, 95% CI 8 to 26). Incidence of sacral pressure ulcers ≥ II stage did not differ significantly between the two groups. No adverse skin reactions and discomfort attributable to the foam application were reported., Conclusion: A sacral multi-layer silicone-adhesive polyurethane foam in addition to standard preventive care is effective for pressure ulcers prevention in at-risk hospitalized patients admitted to medical and surgical units., Trial Registration: ClinicalTrials.gov NCT03900455. The registration (April 1st, 2019) occurred before the first patient was enrolled (October 21st, 2019)., Competing Interests: Declaration of Competing Interest None declared. Smith & Nephew signed an agreement to supply the dressings free of charge for all the patients in the study without influencing any phase of the research project., (Copyright © 2022.

- Abstract
The oculomotor system plays an important role in the development of migraines. This is an observational study that aims to investigate the rehabilitative efficacy of muscle energy therapy (MET) in reducing migraine symptoms. MET was based on post-isometric relaxation and reciprocal inhibition, targeting the extraocular muscles. Patients diagnosed with chronic migraines and positive results in the Smooth Pursuit Eye Movement Test were enrolled in the study. The effects of treatment were assessed using the following questionnaires: Migraine Disability Assessment (MIDAS), Neck Disability Index (NDI), Pittsburg Sleep Quality Index (PSQI), Dizziness Handicap Inventory (DHI), and the neck range of motion (ROM). Additionally, rheological parameters of neck muscles were assessed. We reported beneficial effects of MET on the amelioration of the frequency of headaches, neck pain and dizziness-related disabilities and disordered sleep. However, benefits concerning the neck motion and rheological properties of oculomotor structures were unconvincing. In conclusion, the study showed advantageous effects of manual oculomotor therapy consisting of reductions in migraine-related painful symptomatology. The results diminish the role of ocular muscle mechanical properties in the genesis of migraine, shifting attention to the modulatory role of the neuromuscular ocular component, likely involving trigeminal innervation, which can be subject to migraine manual therapy., (© 2022.

- Abstract
Extremely low-frequency electromagnetic field (ELF-MF) therapy is a promising treatment for chronic pain, given its ability to interact with body homeostasis using water-mediated transmission mechanisms typical of quantum medicine. The present study aims to assess the effects of ELF-MF therapy on chronic pain in 49 patients suffering from various musculoskeletal disorders. The therapy was applied through a Quec Phisis setup generating the electromagnetic field as the ion cyclotronic resonance. Patients underwent eight therapy sessions of 45 min each performed every other day. The bioimpedance assessment was based on the comparison of the height-adjusted body resistance (R/h) and reactance (Xc/h) measured during the first and last sessions of eight-session treatment. Pain perception was quantified using the standard visual-analog scale. We found significant increases in both R/h and Xc/h parameters of body bioimpedance after electromagnetic therapy corresponding with reductions in pain perception. We conclude that the ELF-MF therapy can restore the body's state of health and thus seems a valid therapeutic approach for the treatment of musculoskeletal-derived pain., (© 2022.

- Abstract
Capacitive and resistive electric transfer (TECAR) modes of therapy use radiant energy to generate endogenous heat and are used for musculoskeletal disorders for their analgesic, decontracting, and elasticizing properties. While the capacitive mode is supposed to interact with soft tissues, the resistive mode interacts more with hard tissues. This study aims to investigate whether the successive order of the two modes during their application could make a difference concerning the outcome. The study included 40 patients affected by chronic non-specific low back pain. Patients were assessed using algometry, before and immediately after the therapeutic intervention, and thermal imaging, before, immediately after, and then 30 and 60 min after the intervention. Each patient had two TECAR interventions on different days of a total of 20 min each, with a resistive followed by capacitive mode and conversely, capacitive followed by resistive mode. The capacitive mode alternated with the resistive mode by 10 min during either intervention. Results showed that the effects consisting of temporary increases in the superficial temperature of the lower back and pressure pain threshold were alike for both interventions. We conclude that TECAR therapy reduces low back pain regardless of the operative mode adopted, with only an insignificant advantage when starting the sequence from the resistive application., (© 2022.

- Abstract
The last decade has witnessed the identification of several families affected by hereditary non-syndromic hearing loss (NSHL) caused by mutations in the SMPX gene and the loss of function has been suggested as the underlying mechanism. In the attempt to confirm this hypothesis we generated an Smpx-deficient zebrafish model, pointing out its crucial role in proper inner ear development. Indeed, a marked decrease in the number of kinocilia together with structural alterations of the stereocilia and the kinocilium itself in the hair cells of the inner ear were observed. We also report the impairment of the mechanotransduction by the hair cells, making SMPX a potential key player in the construction of the machinery necessary for sound detection. This wealth of evidence provides the first possible explanation for hearing loss in SMPX -mutated patients. Additionally, we observed a clear muscular phenotype consisting of the defective organization and functioning of muscle fibers, strongly suggesting a potential role for the protein in the development of muscle fibers. This piece of evidence highlights the need for more in-depth analyses in search for possible correlations between SMPX mutations and muscular disorders in humans, thus potentially turning this non-syndromic hearing loss-associated gene into the genetic cause of dysfunctions characterized by more than one symptom, making SMPX a novel syndromic gene.

- Abstract
Chronic nonspecific low back pain is a frequent clinical condition affecting the general population and influencing disability level and quality of life. We performed a single-blinded, randomized, and controlled study to compare the effectiveness of manual pressure release (MPR) and electrical neuromodulation (ENM) treatments in the management of chronic low back pain. There were 20 patients with chronic low back pain randomly assigned to 6 treatment sessions with either technique. Both groups were treated for 2 days a week for 3 weeks. Myofascial trigger points (MTrPs) were identified and skin conductance, pressure-pain threshold, postural changes, and the Oswestry Disability Index were assessed before and after each treatment session, along with the protocol-end data compared against the baseline data in each group. We found an outstanding and about equal deactivation of MTrPs from pre- to post-treatment in both groups, reducing disability in patients with chronic low back pain. The study highlights the ENM as a reliable tool for the evaluation of MTrPs, given a high agreement with the MPR. The effect on the neuromuscular condition of treating the "key trigger points" found in this study advances the knowledge of medical rehabilitation.

- Abstract
The small muscle protein, X-linked (SMPX) gene encodes a cytoskeleton-associated protein, highly expressed in both cardiac and skeletal muscles, as well as in fetal inner ears, with suggested roles as mechanotransductor. Recently, several mutations in the SMPX gene have been associated with X-chromosomal progressive deafness in human. However, very little information is known concerning the roles of SMPX, and no in-vivo models are currently available. Therefore, we characterized the zebrafish ortholog of SMPX to pave the way towards the establishment of a biotool for future functional studies. Despite the genome duplication occurred in the ancestry of teleosts, zebrafish retain only one copy of smpx which shares a high degree of similarity with the mammalian counterpart in terms of genomic organization, syntenic map, and encoded protein. RT-PCR, as well as whole-mount in-situ hybridization and immunofluorescence analyses, revealed that smpx is expressed in several embryonic areas starting from the 4-somite stage. Specifically, smpx mRNA marked the Kupffer's vesicle (KV), the somites, the myocardium, the hair cells of the anterior and the posterior macula of the inner ear, the pronephric ducts, and the muscles of the branchial arches, eyes and pectoral fins. According to our data, zebrafish smpx expression pattern closely resembles that observed in mouse and human, supporting the notion that zebrafish might represent a suitable in-vivo model to disclose the cellular and molecular mechanisms underlying the involvement of SMPX in development and disease., Competing Interests: Declaration of competing interest The authors have no conflicts of interest to be declared., (Copyright © 2020 Elsevier B.V.

Objectives: This study aims to verify whether neuromuscular therapy (NMT) or pharmacology therapy (PT) is more effective for reducing symptoms in women affected by primary dysmenorrhea and the effects associated with each treatment., Design: A controlled, randomized, single-blind clinical trial within the framework of the chair of physical medicine and rehabilitation of the University "G. d'Annunzio" of Chieti-Pescara. The study was conducted on a sample of 60 women suffering from primary dysmenorrhea. Subjects were randomly divided in two groups (A and B). Group A was treated with NMT and group B with PT. Group B was given ibuprofen or naproxen because they are considered the best painkillers for this condition. Group A was treated with 8 neuromuscular manual lumbosacral and abdominal therapy sessions twice per week for 4 weeks. Results were analyzed at the beginning (T0) and end (T1) of the study with a menstrual distress questionnaire, brief pain inventory, and visual analogue scale. Twenty patients from Group A were selected for evaluation of their maintenance of the eventual improvement that was detected in T1 at follow-up (T2)., Results: Both therapies had significant short-term effects in reducing the perception and duration of pain. However, NMT appears to give more improvements in the duration of pain. NMT had a long-term effect on perception of pain because patients conserved the positive effects of treatment after 4 weeks. NMT also had a long-term effect on duration of pain because patients conserved benefits of treatment, but this improvement started to decrease after 4 weeks., Conclusions: In the treatment of primary dysmenorrhea, NMT represents a valid therapeutic alternative method to PT. NMT is free from potential adverse effects of analgesics, is noninvasive, and is easy to perform.

- Abstract
This review updates the knowledge on the use of bioprogressive philosophy in current rehabilitation paradigms, focusing on age-related ailments and antiaging strategies. It is a holistic approach that combines aspects of biology and function into the realm of rehabilitation therapy. The bioprogressive philosophy, with assistance of modern technological developments, such as microgravity-producing devices and techniques, enables personalized and targeted therapeutic approach that seems the most effective in rehabilitation and prevention of neuro-myo-sensory disorders that compromise the homeostatic body harmony, particularly in old age. The review defines the aging, discusses the most common physical dysfunctions, linked to posture, balance, or gait, and gives cues to modern antiaging rehabilitative approaches. The emphasis is put on the proprio-neuromuscular facilitation, a combination of stretch technique that steps into the bioprogressive approach, as currently the best method in the world of physical rehabilitation.

- Abstract
Illicit drugs have been recently identified as a serious environmental problem because of the growing evidence regarding their occurrence in aquatic environment and potential toxicity towards non-target organisms. Among them, cocaine (COC) and its main metabolites, namely benzoylecgonine (BE) and ecgonine methyl ester (EME), are commonly measured in freshwaters worldwide at levels that might cause diverse sub-lethal effects to aquatic organisms. Thus, the present study was aimed at investigating the potential adverse effects induced by the exposure to environmental concentrations (0.04, 0.4, 4 and 40 nM) of COC, BE, and EME on zebrafish (Danio rerio) embryos at 96 h post fertilization. Cytotoxicity was assessed by the Trypan Blue exclusion method, while primary and fixed genetic damages were evaluated by the Single Cell Gel Electrophoresis (SCGE) assay, and the DNA diffusion assay together with the Micronucleus test, respectively. The involvement of oxidative stress in the mechanism of action (MoA) of all tested drugs was assessed by measuring the activity of defense enzymes (SOD, CAT, GPx, and GST) and the expression of their encoding genes. Exposure to COC and both metabolites significantly reduced cell viability, increased DNA fragmentation and promoted the onset of apoptotic cells and micronuclei in zebrafish embryos. Results from oxidative stress-related endpoints and gene expression suggested that the observed genotoxicity may be caused by an overproduction of free radicals that imbalanced the oxidative status of embryos. The integration of biomarker responses into a synthetic index showed that at each tested concentration, BE and EME had a similar toxicity and were both more toxic than COC. Our data confirmed the potential toxicity of environmental concentrations of COC, BE, and EME, suggesting the need of further in-depth studies to shed light on their MoA and long-term toxicity towards non-target aquatic species., (Copyright © 2017 Elsevier Ltd.

- Abstract
The protocols described here are designed to allow researchers to study cell communication without altering the integrity of the environment in which the cells are located. Specifically, they have been developed to analyze the electrical activity of excitable cells, such as spinal neurons. In such a scenario, it is crucial to preserve the integrity of the spinal cell, but it is also important to preserve the anatomy and physiological shape of the systems involved. Indeed, the comprehension of the manner in which the nervous system-and other complex systems-works must be based on a systemic approach. For this reason, the live zebrafish embryo was chosen as a model system, and the spinal neuron membrane voltage changes were evaluated without interfering with the physiological conditions of the embryos. Here, an approach combining the employment of zebrafish embryos with a FRET-based biosensor is described. Zebrafish embryos are characterized by a very simplified nervous system and are particularly suited for imaging applications thanks to their transparency, allowing for the employment of fluorescence-based voltage indicators at the plasma membrane during zebrafish development. The synergy between these two components makes it possible to analyze the electrical activity of the cells in intact living organisms, without perturbing the physiological state. Finally, this non-invasive approach can co-exist with other analyses (e.g., spontaneous movement recordings, as shown here).

- Abstract
Defects in the control of Wnt signaling have emerged as a recurrent mechanism involved in cancer pathogenesis and acute myeloid leukaemia (AML), including the hematopoietic regeneration-associated WNT10B in AC133
bright leukaemia cells, although the existence of a specific mechanism remains unproven. We have obtained evidences for a recurrent rearrangement, which involved the WNT10B locus (WNT10BR ) within intron 1 (IVS1) and flanked at the 5' by non-human sequences whose origin remains to be elucidated; it also expressed a transcript variant (WNT10BIVS1 ) which was mainly detected in a cohort of patients with intermediate/unfavorable risk AML. We also identified in two separate cases, affected by AML and breast cancer respectively, a genomic transposable short form of human WNT10B (ht-WNT10B). The intronless ht-WNT10B resembles a long non-coding RNA (lncRNA), which suggests its involvement in a non-random microhomology-mediated recombination generating the rearranged WNT10BR . Furthermore, our studies supports an autocrine activation primed by the formation of WNT10B-FZD4/5 complexes in the breast cancer MCF7 cells that express the WNT10BIVS1 . Chemical interference of WNT-ligands production by the porcupine inhibitor IWP-2 achieved a dose-dependent suppression of the WNT10B-FZD4/5 interactions. These results present the first evidence for a recurrent rearrangement promoted by a mobile ht-WNT10B oncogene, as a relevant mechanism for Wnt involvement in human cancer.- Published
