The rise in antifungal resistance and side effects of conventional treatments drive the search for innovative therapies like Photodynamic Therapy (PDT). This study explored the efficacy of PDT mediated by gutiferone, an isolated compound from red propolis, for candidiasis treatment. Multiple evaluation methods were employed, including determining the minimum inhibitory concentration (MIC) via broth microdilution, quantifying biomass using crystal violet detachment, and cell counting through total plate count. PDT mediated by gutiferone was also assessed in five groups of mice, followed by histopathological examination and agar plating of lingual tissue samples. Among the seven Candida species tested, gutiferone displayed efficacy against C. albicans, C. glabrata , and C. tropicalis , with MIC values of 1000 μg/mL. In C. tropicalis biofilms, exposure to gutiferone led to a reduction of 1.61 Log10 CFU/mL. PDT mediated by gutiferone achieved an average reduction of 3.68 Log10 CFU/mL in C. tropicalis biofilm cells, underscoring its potent fungicidal activity. Histopathological analysis revealed fungal structures, such as pseudohyphae and hyphae, in infected groups (G2) and irradiated mice. In contrast, groups treated with gutiferone or subjected to gutiferone-assisted PDT (G5) exhibited only few blastoconidia. Furthermore, CFU/mL assessments in lingual tissue post-treatment demonstrated a significantly lower count (0.30 Log10 CFU/mL) in the G5 group compared to G2 (2.43 Log10 CFU/mL). These findings highlight the potential of PDT mediated by gutiferone as a promising alternative for managing denture stomatitis. Future research and clinical investigations offer the promise of validating its clinical applicability and improving outcomes in the treatment of oral candidiasis. • Antifungal resistance drives Photodynamic Therapy exploration. • Gutiferone's efficacy against Candida species. • Potent fungicidal activity in Candida tropicalis. • Histopathological improvement in group treated simultaneously with photodynamic therapy and gutiferone. • Gutiferone-assisted Photodynamic Therapy for oral candidiasis.

This paper assesses how economic freedom is affected by the ideological stance, being the first to analyse the role of dictatorial regimes and their ideological orientations. Using annual data for 145 countries over the period 2000‐2017 and a two‐step system GMM estimator, this study finds that democracies do promote more economic freedom than authoritarian regimes, but not in all circumstances The probability that economic liberalization is promoted is higher for right‐wing dictatorships than for other autocracies and comparable to other types of democratic ruling, with the exception of right‐wing democratic governments that strongly benefit liberalization. These right‐wing governments, alongside (the negative effect of) non‐right‐wing dictatorships, seem to be the main contributors to explaining why democracies in recent years are promoting more economic liberalization than autocracies. Additionally, our results suggest that democratic governments not ideologically identifiable seem to share a common dislike for policies that promote liberalization. [ABSTRACT FROM AUTHOR]

• We analyze the drivers of sovereign rating phases via discrete-time Weibull models. • For speculative-rated sovereigns, reputation build-up as good borrowers is gradual. • The reputation of investment-grade sovereigns remains unchanged as time passes. • The length of both phases significantly depends on the country's economic conditions. • Better governance quality helps to reduce the duration of speculative-grade phases. Using long-term sovereign ratings data for a panel of 130 countries over the last three decades, we investigate the duration and determinants of sovereign rating phases through the lens of discrete-time Weibull models. We find that the likelihood of the end of the 'speculative-grade' phase increases as time goes by (i.e. there is positive duration dependence), but the 'investment-grade' phase is not duration dependent. Thus, for sovereigns rated as speculative, the build-up of reputation as good borrowers is a gradual process, whereas the reputation of investment-grade sovereigns solidifies and remains unchanged as time passes. However, the length of both phases significantly depends on the country's economic conditions. In particular, lower inflation, stronger growth and sounder fiscal policies shorten (prolong) the speculative- (investment-) grade phase. In addition, better governance quality helps to reduce the duration of speculative-grade phases. [ABSTRACT FROM AUTHOR]

Purpose: This paper analyses the collapse of credit booms into soft landings or systemic banking crises. Design/methodology/approach: A discrete-time competing risks duration model is employed to disentangle the factors behind the length of benign and harmful credit booms. Findings: The results show that economic growth and monetary authorities play the major role in explaining the differences in the length and outcome of credit booms. Moreover, both types of credit expansions display positive duration dependence, i.e. both are more likely to end as they grow older, but hard landing credit booms have proven to be longer than those that land softly. Originality/value: This paper contributes to our understanding of what affects the length of credit booms and why some end up creating havoc and others do not. In particular, it calls the attention to the important role that Central Bank independence plays regarding credit booms length and outcome. [ABSTRACT FROM AUTHOR]

Abstract This article analyses the incidence of politically driven cycles on the functional components and sub-components of government expenditures over a group of 18 European countries during the period 1990–2012. An LSDVC estimator is employed in the empirical analysis. The results provide evidence of political opportunism at aggregated and disaggregated levels of public expenditures. The expenditure components that have proved to be more related to that behaviour are public services, education, social protection and some sub-components of health expenditure, items that tend to generate outcomes that are more visible to voters. Some disaggregated evidence of partisan manipulation is also found. Highlights • This paper analyses the incidence of politically driven cycles on the functional components of government expenditures. • An LSDVC estimator is employed over a panel of 18 countries for the period 1990–2012. • The results point out to the presence of political opportunism at aggregated and disaggregated levels of public expenditures. • Spending in public services, health, education and social protection is increased in election years.

This paper analyses the impact of elections, partisan and political support effects on the dynamics of human development in a panel of 82 countries over the period 1980–2013. A Generalised Method of Moments(GMM) estimator is employed and the results point out to the presence of an electoral cycle in the growth rate of human development. Majority governments also influence it, but no evidence is found regarding partisan effects. The electoral cycles have proved to be stronger in non-OECD countries, in countries with less frequent elections, with lower levels of income and human development, in presidential and non-plurality systems and in proportional representation regimes.

We employ a discrete-time parametric duration model on a group of 121 countries over the period 1970-2011 and find that the probability of the end of financial markets' shutdown and reaccess falls as these events become longer. We also show that: (1) shutdown episodes are longer when economic prospects are poor and the degree of financial openness falls, the chief executive has been in office for long periods, and the country has a default history and (2) spells of reaccess tend to be longer when economic growth improves and financial openness increases, there are neither government crises nor government instability, and the country did not default in the past.

Building on a narrative approach to identify episodes of fiscal consolidation, data for a group of seventeen industrial countries over the period 1978–2009, and continuous-time duration models, we find evidence suggesting that the likelihood of a fiscal consolidation ending increases over time, but only for programmes that last fewer than six years. Additionally, fiscal consolidations tend to last longer in non-European than in European countries. Our results emphasize that chronic fiscal imbalances might lead to a vicious austerity cycle, while discipline in the behaviour of fiscal authorities is a means of achieving credible and shorter adjustment measures. Therefore, fiscal fatigue is likely to compromise the implementation and successfulness of fiscal consolidation programmes. [ABSTRACT FROM AUTHOR]
