The widespread use of antibiotics drives the evolution antimicrobial-resistant bacteria (ARB), threatening patients and healthcare professionals. Therefore, development novel strategies to combat resistance is recognized as a global priority. two methods ARB are new or reduction in existing resistances. Development laborious slow-progressing task that no longer safe reserve against looming risks. In this research, we suggest method for reducing extend efficacious lifetime current...
Gram-negative bacteria and in biofilms are very difficult to eradicate the most antibiotic-resistant bacteria. Therapeutic alternatives less susceptible mechanisms of resistance urgently needed respond an alarming increase resistant nosocomial infections. Antibacterial photodynamic inactivation (PDI) generates oxidative stress that triggers multiple cell death more counteract by We explore PDI multidrug-resistant bacterial strains collected from patients show how positive charge distribution...
Multidrug-resistant bacteria are one of the most serious threats to infection control. Few new antibiotics have been developed; however, lack an effective mechanism their action has worsened situation. Photodynamic inactivation (PDI) can break antimicrobial resistance, since it potentiates effect antibiotics, and induces oxidative stress in microorganisms through interaction light with a photosensitizer. This paper addresses application PDI for increasing bacterial susceptibility helping...
Significance Hospital-acquired infections also caused by multidrug-resistant bacteria are currently one of the most severe problems that our society faces, which constitute an excellent risk for humankind. The absence alternatives to combat these types leaves humanity highly vulnerable. Therefore, it becomes imperative develop new technologies fight bacterial infections, with alternative mechanisms action relative classical antibiotics. Since ventilator-associated pneumonia (VAP) occurs in...
Abstract While plant microorganisms can promote plants by producing natural antibiotics, they also be vectors for disease transmission. Contamination from management practices and the surrounding environment adversely affect plants, leading to infections hindered growth due microbial competition nutrients. The recirculation of nutrient-rich fluids facilitate transport between vegetables in hydroponic production system. This issue addressed through application decontamination method liquid....
Fresh produce contamination poses a significant public health risk. Traditional disinfection methods using chemical solutions, while effective, raise environmental and concerns. This study explores UVC irradiation, promising non-chemical alternative proven to be effective against broad spectrum of microorganisms. We investigated the optimal dosage for reducing microorganisms on fresh vegetables washed in water. Our findings suggest that dosages approximately 2 mJ/cm2 water 9 achieve...
Abstract Antibiotic failures in treatments of bacterial infections from resistant strains have been a global health concern, mainly due to the proportions they can reach coming years. Making microorganisms susceptible existing antibiotics is an alternative solve this problem. This study applies physicochemical method standard treatment for modulating synergistic response towards circumventing mechanisms resistance. Photodynamic inactivation protocols (curcumina 10 µM, J/cm 2 ) and their...
Along the past years, a national program to implement photodynamic therapy (PDT) for nonmelanoma skin cancer (NMSC) was performed over Brazilian territory. Using strategy involving companies, bank, and medical partners, equipment, medication, protocols were tested in multicenter study. With results collected 6 we could reach great deal of advances concerning use PDT cancer. We present overall reached discuss several aspects about it, including public politics treatment. A discussion...
The photodynamic therapy (PDT) is an alternative technique that can be indicated for superficial basal cell carcinoma (sBCC), Bowen's disease and actinic keratosis with high efficiency. objective of this study to present the importance fluorescence imaging PDT guidance monitoring in real time. Confirming lesion well prepared photosensitizer shows a homogenous distribution, outcome after few sessions will positive recurrence should lower. Our proposition use widefield evaluate protocol situ...
The emergence of drug-resistant bacteria is considered a critical public health problem. need to establish alternative approaches countering resistant microorganisms unquestionable in overcoming this Among emerging alternatives, antimicrobial photodynamic therapy (aPDT) has become promising control infectious diseases. aPDT based on the activation photosensitizer (PS) by particular wavelength light followed generation reactive oxygen. These interactions result production oxygen species,...
Objective: The aim of this study was to evaluate the effectiveness a new handheld equipment based on mercury low-pressure vapor lamp.

Background data: incidence hospital infections has increased recent years. Despite variety available chemicals...
Abstract BACKGROUND Resistant populations of Ae. aegypti have been a major problem in arboviruses epidemic areas, generating strong demand for novel methods vector control. In this regard, our group has demonstrated the use curcumin as an efficient photoactive larvicide to eliminate larvae. This work was aimed evaluate (Rockefeller) development under sublethal conditions, using curcumin/d‐mannitol (DMC) formulation. The photolarvicidal efficacy semi‐field and field conditions (wild...
Transparent Conductive Oxides (TCOs) have been widely used as sensors for various hazardous gases. Among the most studied TCOs is SnO2, due to tin being an abundant material in nature, and therefore accessible moldable-like nanobelts. Sensors based on SnO2 nanobelts are generally quantified according interaction of atmosphere with its surface, changing conductance. The present study reports fabrication a nanobelt-based gas sensor, which electrical contacts self-assembled, thus do not need...
