State responsiveness, collective efficacy and threat perception: Catalyst and complacency effects in opposition to crime across eight countries.

Collective action can be a crucial tool for enabling individuals to combat crime in their communities. In this research, we investigated individuals' intentions to mobilize against organized crime, a particularly impactful form of crime characterized by its exercises of power over territories and communities. We focused on individuals' views and perceptions of state authorities, examining how these views may be linked to intentions for collective mobilization.

The role of ventromedial prefrontal cortex and temporo-parietal junction in third-party punishment behavior.

Third parties punish, sacrificing personal interests, offenders who violate either fairness or cooperation norms. This behavior is defined altruistic punishment and the degree of punishment typically increases with the severity of the norm violation. An opposite and apparently paradoxical behavior, namely anti-social punishment, is the tendency to spend own money to punish cooperative or fair behaviors.

Are Some Countries More Honest than Others? Evidence from a Tax Compliance Experiment in Sweden and Italy.

This study examines cultural differences in ordinary dishonesty between Italy and Sweden, two countries with different reputations for trustworthiness and probity. Exploiting a set of cross-cultural tax compliance experiments, we find that the average level of tax evasion (as a measure of ordinary dishonesty) does not differ significantly between Swedes and Italians. However, we also uncover differences in national "styles" of dishonesty.

"Willing to Pay?" Tax Compliance in Britain and Italy: An Experimental Analysis.

As shown by the recent crisis, tax evasion poses a significant problem for countries such as Greece, Spain and Italy. While these societies certainly possess weaker fiscal institutions as compared to other EU members, might broader cultural differences between northern and southern Europe also help to explain citizens' (un)willingness to pay their taxes? To address this question, we conduct laboratory experiments in the UK and Italy, two countries which straddle this North-South divide. Our design allows us to examine citizens' willingness to contribute to public goods via taxes while holding institutions constant.

Fair play doesn't matter: MEP modulation as a neurophysiological signature of status quo bias in economic interactions.

Transcranial magnetic stimulation (TMS) studies show that watching others' movements enhances motor evoked potential (MEPs) amplitude of the muscles involved in the observed action (motor facilitation, MF). MF has been attributed to a mirror neuron system mediated mechanism, causing an excitability increment of primary motor cortex. It is still unclear whether the meaning an action assumes when performed in an interpersonal exchange context could affect MF.

Expression of hepatitis B surface antigen major subtypes in Pichia pastoris and purification for in vitro diagnosis.

This study describes the expression in Pichia pastoris of hepatitis B surface antigens (HBsAg) corresponding to the S region of the four major subtypes: adr, adw2, ayr and ayw3 and to the preS2-S region of the two subtypes adr and adw2. The recombinant yeast strains have been selected amongst methanol utilization positive (Mut+) or sensitive strains (Mut s) and cultivated to high cell density in bioreactor using a short protocol. Our results prove the efficiency of P.

Molecular cloning, overexpression in Escherichia coli, and purification of 6x his-tagged C-terminal domain of Clostridium difficile toxins A and B.

Genomic DNA from ribotype-01 and -17 Clostridium difficile strains was used for amplification of the sequences encoding the carboxy-terminal domain of toxins A (TcdA) and B (TcdB). The deduced C-terminal TcdB ribotype-01 and -17 domains share 99.5% amino acid sequence identity while TcdA ribotype-17 comprises a 607 amino acid deletion compared to TcdA-01.

[Effectiveness of oral supplements of folates, vitamins B12 and B6 in hemodialysed patients. Preliminary results after 5 months of follow-up].

Background: Elevated serum levels of homocysteine have increasingly been associated as a risk factor of cardiovascular disease. Recent reports demonstrated that supplements of folates, vitamin B12 (B12) and vitamin B6 (B6) are effective in correcting serum Hcy levels in hemodialysed patients.

Aim: to assess the effectiveness of oral supplements of folates, B12 and B6, in order to reduce serum Hcy levels in our cohort of hemodialysed patients.

[Infections from extemporaneous catheters for hemodialysis. Experience in a center].

Background And Aims: This study reports a retrospective evaluation of the predominance of infection in 67 dual lumen central venous catheters (CVC), 35 of which were positioned in the femoral vein by the nephrological team and 32 in the subclavian vein by anesthetists.

Methods: The microorganisms responsible for infection, the prevalence of clinically symptomatic infections, the relationship between CVC-correlated infection and the time the catheter remained inserted were evaluated, together with a comparison between the two different insertion sites.

Results: Culture tests, performed using Maki's semiquantitative technique, gave positive results in 16/67 (23.

[Brown tumor of the jaws].

Brown tumour is one of the forms in which fibrous-cystic osteitis, which represents the terminal stage of the bone remodelling processes during primary or secondary hyperparathyroidism, is manifested. For years brown tumour was regarded as a typical lesion of primary hyperparathyroidism, but cases of brown tumours in patients with hyperparathyroidism secondary to renal failure were increasingly often reported in the literature. From an epidemiological point of view, the frequency of brown tumours in patients with renal insufficiency is extremely variable, as is the bone site affected.

Scleroderma renal crisis is still a life-threatening syndrome.

Scleroderma renal crisis (SRC) was known as a rare and catastrophic syndrome responsible for acute renal failure (ARF) in a context of widespread microvascular disease occurring in progressive systemic sclerosis (PSS). Following pathogenetic hypoteses, angiotensin converting enzyme (ACE) inhibitors, plasma infusions (PI), and plasma-exchange (PE) have been employed in SRC with favorable results. Our purpose was to verify whether these therapies have consistently changed the fatal prognosis of SRC, even in our experience.

[Comparison between biopsy data and the resistive index obtained by Doppler echography in the evaluation of the transplanted kidney].

Doppler sonography is nowadays considered as a "first step" tool for diagnosis of vascular complications in kidney transplantation. Quite recently, it has been sometimes considered useful and effective investigation in order to obtain information about parenchymal dysfunctional pathologies, particularly about acute rejection. This has been obtained by studying the variation of resistive indexes.
