A cyclam salt as an antifungal agent: Interference with Candida spp. and Crypto...

The importance of fungal infections, particularly those caused by yeasts, is increasing among the medical community. Candida albicans and Cryptococcus neoformans are amongst the high-priority fungal species identified by the World Health Organization (WHO) and are considered in the critical group, while Candida krusei is included in the medium-priority group. The cyclam salt H4[H2(4-CF3PhCH2)2Cyclam]Cl4 proved ...

Graphene nanoparticles on refractive index of cancerous breast tissues: spectra...

This work presents a study on the influence of graphene nanoparticles on the refractive index (RI) for application in breast tissues as an aid in the diagnosis of cancerous cells, using a spectral approach to evaluate the behaviour of glycerine and water-based nanofluids in various proportions. Glycerine-water solutions with different volumetric fractions of graphene were prepared, and the RI was measured using...

Renewable energy transition in Portugal, balance, and perspectives: opportuniti...

Humanity depends on energy, and its consumption is directly related to social habits, culture, and quality of life. The population growth and the search for a better quality of life lead to a significant increase in energy consumption worldwide. The energy consumed is mainly produced from fossil fuels with high carbon content, and their reserves are heading toward depletion. To reverse the situation, it is nece...

The influence of social and economic environment on health

One health approach brings together environment, human and animal health as interdependent determinants of health, including the social and economic conditions. This chapter provides insights on how social and economic factors can influence health through cultural habits, lifestyles, conditioned access to health care, to green spaces, to healthy food, exposure to pollution and to poor sanitation conditions. The...

Is MRSA/MSSA a contamination risk on surfaces of the dental equipment?

Bacteriophage Phi 6 as surrogate and human-harmless viruses to study anti-SARS-...

Given safety challenges in conducting laboratory work with highly infectious human coronaviruses (pathogenicity, genetic mutations rate, biosafety level 3 and 4 requirements), many researchers have valued the potential of bacteriophages as appropriate viral surrogate to measure humans enveloped virus’ survival, transfer and removal. The use of phage Φ6 seems to be useful as coronavirus surrogate to assess the e...

Identification of nasal carriage of Staphylococcus aureus among nursing student...

Staphylococcus aureusis considered one of the most frequently isolated bacteria in the community and in the hospital environment, beingassociated with several infections.Healthcare professionalsrepresent a group vulnerable to Staphylococcus aureus and MRSAcolonization, therefore being potential disseminators of these microorganisms during their care activities.The aim of this study was to evaluate the dynamics ...

Health monitoring and intervention plan on oil industry workers: results from a...

Oil industry workers are particularly vulnerable to risks related to their especial working conditions like exposure to hazardous chemicals, explosions and fires, working in confined spaces and often in remote areas or in offshore platforms. Dedicated work health surveillance plans that take into consideration environmental risks are of the utmost importance to safeguard workers health and to communicate identi...

Detection of Staphylococcus aureus (MRSA/MSSA) in surfaces of dental medicine e...

Methicillin-Resistant Staphylococcus aureus (MRSA) represents one of the major causes of nosocomial infections, leading to high mortality. Surfaces in clinics, as well as the attending uniform and the hands of the dental doctor can be MRSA reservoirs. Having this in mind, the purpose of this study was to evaluate the presence of Methicillin-Sensitive Staphylococcus aureus (MSSA) and MRSA on dental medicine equi...
