Abstract
The larval zebrafish has emerged as a very useful model organism to study the neuronal circuits controlling neuroendocrine and behavioral responses to stress. This protocol describes how to expose zebrafish larvae to hyperosmotic stress and test whether candidate populations of neurons are activated or inhibited by the stressor using a relatively rapid immunofluorescence staining approach. This approach takes advantage of the phosphorylation of the extracellular signal-regulated kinase (ERK) upon neuronal activation. For complete details on the use and execution of this protocol, please refer to Corradi et al. (2022).

Abstract
Animals possess neuronal circuits inducing stress to avoid or cope with threats present in their surroundings, for instance, by promoting behaviors, such as avoidance and escape. However, mechanisms must exist to tightly control responses to stressors, since overactivation of stress circuits is deleterious for the wellbeing of an organism. The underlying neuronal dynamics responsible for controlling behavioral responses to stress have remained unclear. Here, we describe a neuronal circuit in the hypothalamus of zebrafish larvae that inhibits stress-related behaviors and prevents excessive activation of the neuroendocrine pathway hypothalamic-pituitary-interrenal axis. Central components of this circuit are neurons secreting the neuropeptide Galanin, as ablation of these neurons led to abnormally high levels of stress. Surprisingly, we found that Galanin has a self-inhibitory action on Galanin-producing neurons. Our results suggest that hypothalamic Galanin-producing neurons play an important role in fine-tuning stress responses by preventing potentially harmful overactivation of stress-regulating circuits.

Abstract
Animals adapt their behaviors to their ever-changing needs. Internal states, such as hunger, fear, stress, and arousal are important behavioral modulators controlling the way an organism perceives sensory stimuli and reacts to them. The translucent zebrafish larva is an ideal model organism for studying neuronal circuits regulating brain states, owning to the possibility of easy imaging and manipulating activity of genetically identified neurons while the animal performs stereotyped and well-characterized behaviors. The main neuromodulatory circuits present in mammals can also be found in the larval zebrafish brain, with the advantage that they contain small numbers of neurons. Importantly, imaging and behavioral techniques can be combined with methods for generating targeted genetic modifications to reveal the molecular underpinnings mediating the functions of such circuits. In this review we discuss how studying the larval zebrafish brain has contributed to advance our understanding of circuits and molecular mechanisms regulating neuromodulation and behavioral flexibility.

Abstract
Stressful experiences early in life can increase the risk of cardiovascular diseases. However, it remains largely unknown how stress influences susceptibility to the disease onset. Here, we show that exposure to brain-processed stress disrupts myocardial growth by reducing cardiomyocyte mitotic activity. Activation of the glucocorticoid receptor (GR), the primary stress response pathway, reduces cardiomyocyte numbers, disrupts trabecular formation, and leads to contractile dysfunction of the developing myocardium. However, a physiological level of GR signaling is required to prevent cardiomyocyte hyperproliferation. Mechanistically, we identify an antagonistic interaction between the GR and the cytokine interleukin-4 (IL-4) as a key player in cardiac development. IL-4 signals transcription of key regulators of cell-cycle progression in cardiomyocytes via signal transducer and activator of transcription 3 (Stat3). GR, on the contrary, inhibits this signaling system. Thus, our findings uncover an interplay between stress and immune signaling pathways critical to orchestrating physiological growth of the heart.

Abstract
We report on the direct experimental observation of the 7pP23/2→7dD2 optical transitions in 209 and 210 francium isotopes. By continuously monitoring the fluorescence emitted by the isotopes collected in a magneto-optical trap (MOT), the electric dipole transitions 7pP23/2→7dD25/2 of Fr209, not yet experimentally observed, and 7pP23/2→7dD25/2, 7pP23/2→7dD25/2 of Fr210 were detected as sub-Doppler depletion dips of the cold atom population. This approach allowed unambiguous identification of the excited state hyperfine structures, even in the absence of a large stable vapor. Our findings demonstrate the effectiveness and the flexibility of fluorescence monitoring of trap depletion upon laser excitation, and broaden the experimental knowledge of francium isotopes and their electronic and nuclear properties. These results will have a relevant impact on ongoing researches for low-energy testing of fundamental symmetries with francium, from atomic parity non-conservation to the electron dipole moment.

Abstract
Absolute cross sections for isotopically identified products formed in multinucleon transfer in the (136)Xe+(198)Pt system at ∼8 MeV/nucleon are reported. The isotopic distributions obtained using a large acceptance spectrometer demonstrated the production of the "hard-to-reach" neutron-rich isotopes for Z<78 around the N=126 shell closure far from stability. The main contribution to the formation of these exotic nuclei is shown to arise in collisions with a small kinetic energy dissipation. The present experimental finding corroborates for the first time recent predictions that multinucleon transfer reactions would be the optimum method to populate and characterize neutron-rich isotopes around N=126 which are crucial for understanding both astrophysically relevant processes and the evolution of "magic" numbers far from stability.

Abstract
We present here the first evidence of photodesorption induced by low-intensity non-resonant light from an yttrium thin foil, which works as a neutralizer for Rb and Fr ions beam. Neutral atoms are suddenly ejected from the metal surface in a pulsed regime upon illumination with a broadband flash light and then released in the free volume of a pyrex cells. Here atoms are captured by a Magneto-Optical Trap (MOT), which is effectively loaded by the photodesorption. Loading times of the order of the flash rise time are measured. Desorption is also obtained in the continuous regime, by exploiting CW visible illumination of the metallic neutralizer surface. We demonstrate that at lower CW light intensities vacuum conditions are not perturbed by the photodesorption and hence the MOT dynamics remains unaffected, while the trap population increases thanks to the incoming desorbed atoms flux. Even with the Y foil at room temperature and hence with no trapped atoms, upon visible illumination, the number of trapped atoms reaches 10(5). The experimental data are then analyzed by means of an analytical rate equation model, which allows the analysis of this phenomenon and its dynamics and allows the determination of critical experimental parameters and the test of the procedure in the framework of radioactive Francium trapping. In this view, together with an extensive investigation of the phenomenon with (85)Rb, the first demonstration of the photodesorption-aided loading of a (210)Fr MOT is shown.

Abstract
An excitation function of one- and two-neutron transfer channels for the ^{60}Ni+^{116}Sn system has been measured with the magnetic spectrometer PRISMA in a wide energy range, from the Coulomb barrier to far below it. The experimental transfer probabilities are well reproduced, for the first time with heavy ions, in absolute values and in slope by microscopic calculations which incorporate nucleon-nucleon pairing correlations.

Abstract
Measurements of the excitation function for the fusion of (24)Mg+(30)Si (Q=17.89 MeV)have been extended toward lower energies with respect to previous experimental data. The S-factor maximum observed in this large, positive-Q-value system is the most pronounced among such systems studied thus far. The significance and the systematics of an S-factor maximum in systems with positive fusion Q values are discussed. This result would strongly impact the extrapolated cross sections and reaction rates in the carbon and oxygen burnings and, thus, the study of the history of stellar evolution.

Abstract
Buckwheat allergy is considered a rare food allergy outside of Asia. In Europe, buckwheat has been described mainly as a hidden allergen. Data on the prevalence of buckwheat hypersensitivity in non-Asian countries is very poor. The aim of this multicenter study was to evaluate the prevalence of buckwheat sensitization and its association with other sensitizations among patients referred to allergy clinics in different geographic areas of Italy. All patients referred to 18 Italian allergy clinics from February through April 2011 were included in the study and evaluated for sensitization to buckwheat and other allergens depending on their clinical history. A total of 1,954 patients were included in the study and 61.3 percent of them were atopic. Mean prevalence of buckwheat sensitization was 3.6 percent with significant difference between Northern (4.5 percent), Central (2.2 percent) and Southern (2.8 percent) regions. This is, to our knowledge, the largest epidemiological survey on buckwheat allergy reported outside of Asia. Buckwheat is an emerging allergen in Italy, being more frequently associated to sensitization in Northern regions.

Abstract
INTRODUCTION In this short essay, we would like to address a severe divergence observed in Italy between Life Expectancy (LE) and Healthy Life Expectancy (Healthy LE) and a unique trend of worsening in Healthy LE, compared to the other European countries. Both issues emerge in recent data by EUROSTAT Report. METHODS The analysis used by the authors of the EUROSTAT report is based on Sullivan method which combines 2 type of variables: mortality and morbidity data. RESULTS While several European countries started to deal with comparable data about LE since 1960, in Italy, analogous data were available for the first time in EUROSTAT Report only in 1985. In Italy, in the period 1985-2008, there was a good progressive increase in L.E., following the best European values. Nevertheless, while until 2004 Italy was among the European best countries in terms of both LE and Healthy LE at birth, four years later in 2008 there was a shocking loss of 10 years of Healthy LE at birth in newborn girls. In the process, they lost their 2-years previous advantage with respect to males (the latter lost only 6 years of Healthy LE, in the same time span). Looking at healthy LE at age 65 in respect to 2004, Italian women in 2008 could expect to live healthy only about 7 years (as much as men) versus the almost 15 years of the European best values (14 years for men). CONCLUSIONS It is legitimate to wonder why no one official comment has been produced as a reaction after the first year of spectacular decline in Healthy Life Years in Italy: in counter-tendency with European values, from 2004 to 2008 there is a clear evidence of a 10 years drop in Healthy LE among newborn girls. The problem has not been taken into consideration even when the situation clearly appeared to worsen in the following years, dropping 4-6 more years for males and females in 2006 (for newborn babies); two more years of healthy life expectancy have been lost between 2006 and 2007 for each gender. One more year of Healthy Life Expectancy is lost in 2008. And data have not been made available any more, since then, from Italy.

Abstract
AIMS To compare the effects of losartan and amlodipine on myocardial structure and function in hypertensive patients with Type 2 diabetes and left ventricular hypertrophy. METHODS After a 4-week placebo period, patients were randomized to losartan 50 mg (n = 90) or amlodipine 5 mg (n = 91) for 12 months, with a doubling of the dose in patients who did not respond after 4 weeks. Blood pressure was measured in the clinic every month, while conventional echocardiography and acoustic densitometry (integrated backscatter analysis) were performed at the end of the placebo period and after 12 months of treatment. RESULTS Both drugs reduced systolic/diastolic blood pressure to a comparable extent. Losartan significantly reduced left ventricular mass index (-19%, P < 0.001), interventricular septal thickness (-16.6%, P < 0.01) and left ventricular posterior wall thickness in diastole (-13.7%, P < 0.01). Amlodipine also decreased such measurements (-10%, P < 0.01 for left ventricular mass index, -9.3%, P < 0.05 for interventricular septal thickness in diastole and -10.1%, P < 0.05 for posterior wall thickness in diastole), but to a lesser extent than losartan. Both drugs significantly increased the ratio of peak filling velocity at early diastole to that at atrial contraction (E/A ratio) and decreased isovolumetric relaxation time: +13.7% and -8.5% with losartan,(both P < 0.01), and +7.9% and -4.9%, with amlopidine (both P < 0.05). Losartan, but not amlodipine, significantly reduced the relative integrated backscatter compared to baseline of the intraventricular septum (-10%, P < 0.01), and of the left ventricular posterior wall (-12%, P < 0.01), while increasing the cyclic variation of integrated backscatter of both the intraventricular septum (+35%, P < 0.001) and the left ventricular posterior wall (+32%, P < 0.001). CONCLUSIONS Losartan provided a greater attenuation of left ventricular hypertrophy than amlodipine, seemingly as a result of a greater reduction of myocardial fibrosis.

Abstract
The lifetimes of the first excited states of the N = 30 isotones (50)Ca and (51)Sc have been determined using the Recoil Distance Doppler Shift method in combination with the CLARA-PRISMA spectrometers. This is the first time such a method is applied to measure lifetimes of neutron-rich nuclei populated via a multinucleon transfer reaction. This extends the lifetime knowledge beyond the f_{7/2} shell closure and allows us to derive the effective proton and neutron charges in the fp shell near the doubly magic nucleus (48)Ca, using large-scale, shell-model calculations. These results indicate an orbital dependence of the core polarization along the fp shell.

Abstract
An interferometric method is used to improve the accuracy of the 7S-7P transition frequencies of three francium isotopes by 1 order of magnitude. The deduced isotope shifts for 209-211Fr confirm the ISOLDE data. The frequency of the D2 transition of 212Fr--the accepted reference for all Fr isotope shifts--is revised, and a significant difference with the ISOLDE value is found. Our results will be a benchmark for the accuracy of the theory of Fr energy levels, a necessary step to investigate fundamental symmetries.

Abstract
The aim of this double-blind, double-dummy, parallel group study was to compare the effects of delapril-manidipine combination vs a irbesartan-hydrochlorothiazide combination on plasma tissue plasminogen activator (t-PA) and plasmogen activator inhibitor type I (PAI-l) activities in hypertensive patients with type II diabetes mellitus. After a 4-week run-in placebo period, 80 patients (37 male and 43 female), aged 41-65 years, were randomly allocated to an 8-week treatment with delapril 30 mg once daily or irbesartan 150 mg once daily. Thereafter, manidipine l0 mg once daily was added to delapril treatment and hydrochlorothiazide 12.5 mg to irbesartan treatment for a further 8 weeks. Blood pressure (BP), plasma t-PA and PAI-l activities were evaluated at the end of the run-in period, after 4-week monotherapy treatments, and at the end of the combination treatment periods. Both combination treatments, delapril-manidipine and irbesartan-hydrochlorothiazide, produced a greater reduction in systolic BP/diastolic BP (SBP/DBP) values (-27.6/21.8 mmHg and -26.4/20.2 mmHg, respectively) than the respective monotherapies (-15.2/11.7 mmHg with delapril and -16.3/11.3 mmHg with irbesartan). Delapril monotherapy significantly decreased plasma PAI-l activity (-10.4 IU/mI; P<0.05). The addition of manidipine produced a significant increase in t-PA activity (+0.27 IU/mI); P<0.05). Irbesartan monotherapy did not significantly affect the fibrinolytic balance, whereas the addition of hydrochlorothiazide worsened it, producing a significant increase in PAI-l activity (+9.5 IU/ml; P<0.05). In hypertensive patients with type II diabetes mellitus, the combination delapril-manidipine may determine a greater improvement of the fibrinolytic function than the respective monotherapy, while the association irbesartan-hydrochlorothiazide may worsen it.

Abstract
AIMS To identify possible work related sources of psychosocial stress in order to develop pertinent questionnaire items for a cross-sectional health survey of 3000 Italian women flight attendants, and to solicit suggestions on improving survey participation. METHODS Qualitative study in which 26 current and former women flight attendants participated: three focus groups of 6-7 participants each and six in-depth individual interviews. The session themes included positive and negative aspects of the job; relationships with colleagues, superiors, and passengers; perception of occupational risk for serious diseases; compatibility of work and family; and experiences of work related sources of stress and their effect on health. A transcript based analysis of the focus groups and interviews was used to identify emerging themes related to risk factors for mental health problems. RESULTS The participants indicated that mental health was a major concern. Several work related risk factors possibly related to adverse outcomes, such as depression and anxiety, were highlighted. These included isolation and solitude, fears of being inadequate partners and mothers due to job demands, passenger relationships, and lack of protection by employers with respect to workplace exposures and violent passengers. The information gained was used to develop a mental health module for inclusion in the health survey questionnaire which included questions on history of severe depression or anxiety, suicidal ideation or attempt, substance abuse, workplace sexual harassment, social support, leisure time activities, relationship with a partner, and role as mother. CONCLUSIONS Employing qualitative methods to identify work related sources of psychosocial stress enabled development of pertinent questionnaire items for a cross-sectional epidemiological study of women flight attendants. Follow up qualitative research may be necessary in order to put the cross-sectional study findings into context and to explore actions or strategies for preventing work related health problems evidenced from the survey.

Abstract
The aim of this study was to evaluate the effects of long-term monotherapy with four beta-blockers provided with different pharmacological properties on plasma lipids in both normocholesterolemic and hypercholesterolemic hypertensive patients. After a 1-month run-in period on placebo, 70 hypertensive patients with basal total cholesterol (TC) < or = 220 mg/dl were treated for 3 years with propranolol 160 mg/day or atenolol 100 mg/day or bisoprolol 10 mg/day or mepindolol 10 mg/day, while 59 hypertensive patients with basal TC > 220 mg/dl were given the same beta-blockers at the same dosage for 6 months. In both normocholesterolemic and hypercholesterolemic hypertensive patients. HDL-C and triglyceride (TG) levels showed significant changes that appeared to be related to the type of beta-blocker used and to the duration of therapy. Nonselective, non-ISA (intrinsic sympathomimetic activity) propranolol caused the most pronounced changes, decreasing HDL-C and increasing TG concentrations; beta1-selective atenolol and bisoprolol had similar, but less remarkable effects; even more discrete changes were observed on mepindolol (with ISA). The variations in HDL-C and TG values reached their peak in 6-12 months of beta-blocker therapy; then, after a plateau phase, they showed a progressive trend toward pretreatment levels. In hypercholesterolemic patients, the percent change in both HDL-C and TG values was lower compared to normocholesterolemic patients.

Abstract
OBJECTIVE Studies on the effects of chronic exposure to industrial noise on clinic blood pressure (BP) at rest have yielded inconsistent results. The aim of this study was to evaluate the effect of occupational noise exposure on ambulatory blood pressure (ABP) in normotensive subjects. METHODS We studied 476 normotensive workers, aged 20-50 years (systolic blood pressure (SBP) < 140, diastolic blood pressure (DBP) < 90), at a metallurgical factory; 238 were exposed to high levels of noise (> 85 dB), while 238 were not exposed (< 80 dB). Clinical evaluation included measurements of casual BP (by standard mercury sphygmomanometer, Korotkoff sound phase I and V) and heart rate (HR) (by pulse palpation), body height and weight. All subjects underwent a 24 h non-invasive ABP monitoring (by SpaceLabs 90207 recorder; SpaceLabs, Redmond, Washington, USA) twice within 14 days: one during a normal working day and one during a non-working day. Measurements were performed every 15 min. Computed analysis of individual recordings provided average SBP, DBP and HR values for 24 h, daytime working hours (0800-1700 h), daytime non-working hours (1700-2300 h) and night-time (2300-0800 h). RESULTS No significant difference in clinic SBP, DBP and HR was observed between exposed and non-exposed subjects. Results obtained by ABP monitoring showed in the exposed workers: (a) a higher SBP (by a mean of 6 mmHg, P < 0.0001 versus controls) and DBP (by a mean of 3 mmHg, P < 0.0001) during the time of exposure and the following 2 or 3 h, whereas no difference between the two groups was found during the non-working day; (b) an increase in HR, which was present not only during the time of exposure to noise (+3.7 beats-per-minute (bpm), P < 0.0001 versus controls), but also during the non-working hours (+2.8 bpm, P < 0.001) and during the day-time hours of the non-working day (+2.8 bpm, P < 0.003); (c) a significant increase in BP variability throughout the working day. CONCLUSIONS These findings suggest that in normotensive subjects below the age of 50 years, chronic exposure to occupational noise is associated with a transient increase in BP, which is not reflected in a sustained BP elevation. The possible role of repeated BP and HR fluctuations due to frequent and prolonged exposure to noise in accounting for the higher prevalence of hypertension reported in noise-exposed workers above age 50 years, requires longitudinal studies to be clarified.

Abstract
The aim of this study was to compare the effect of antihypertensive treatment with valsartan or cavedilol on sexual activity in hypertensive men who were never treated for hypertension. A total of 160 newly diagnosed hypertensive men (diastolic blood pressure [DBP] > or = 95 mm Hg and < 110 mm Hg), aged 40 to 49 years, all married and without any previous sexual disfunction, were enrolled. After a 4-week placebo period, the patients were divided into two groups: a) 120 patients were randomized to receive carvedilol 50 mg once daily or valsartan 80 mg once daily for 16 weeks according to a double-blind, cross-over design; after another 4-week placebo period, patients were crossed over to the alternative regimen for a further 16 weeks; b) 40 patients were treated with placebo according to a single-blind design for 16 weeks. At the screening visit and every 4 weeks thereafter, blood pressure (BP) was evaluated and patients were interviewed by a questionnaire about their sexual activity. Blood pressure was significantly lowered by both treatments, with a 48% of normalization with valsartan and 45% with carvedilol. During the first month of therapy, sexual activity (assessed as number of sexual intercourse episodes per month) declined with both drugs as compared with baseline, although the decrease was statistically significant in the carvedilol (from 8.2 to 4.4 sexual intercourse episodes, P < .01) but not in the valsartan-treated patients (from 8.3 to 6.6 sexual intercourse episodes, not significant). Ongoing with the treatment the sexual activity further worsened with carvedilol (3.7 sexual intercourse episodes per month) while fully recovered and also improved with valsartan (10.2 sexual intercourse episodes per month). The results were confirmed by the cross-over. Erectile dysfunction was a complaint of 15 patients with carvedilol (13.5%), one patient with valsartan (0.9%), and one patient in the placebo group. These findings suggest that carvedilol induces a chronic worsening of sexual activity, whereas valsartan not only does not significantly worsen sexual activity but may even improve it.

Abstract
An ethnobotanical survey was carried out in the year 1997-1998, in the neighbourhood of the town of Chieti in the Abruzzo region (Central Italy). The information recorded in this paper has been collected by interviewing people born in the area, or who have lived there for many years, and whose knowledge of the medicinal or domestic use of plants represents a personal patrimony uninfluenced by other sources. About 80 species claimed as medicinal (not only in human therapy but also, for example, in veterinary use) and belonging to 43 families are recorded; only the use of the plants identified with certainty is reported. The study pointed out that the heritage of medicinal popular use of such plants, in spite of pharmaceutical technology, is still alive, not only in the memory of the elders and farmers, and that nowadays home-made remedies for simple diseases are still often used: Moreover, the uses of these plants are not only limited to therapeutic purposes, but also extend to domestic and surviving craft activities.
