Photodynamic therapy (PDT) holds promise in biochemical study and tumor treatment. A novel multifunctional nanosystem CaO2 /MnO2 @polydopamine (PDA)-methylene blue (MB) nanosheet (CMP-MB) was designed. CaO2 nanoparticles were encapsulated by MnO2 nanosheet, and then PDA was coated on the surface of CaO2 /MnO2 nanosheets, which could adsorb photosensitizer MB through hydrophobic interaction or π-π stacking. In this nanosystem, CaO2 /MnO2 had the ability of self-production of oxygen, which solved the problem of tumor hypoxia largely...

BACKGROUND: Female chronic pelvic pain (CPP) is defined as intermittent or constant pelvic or lower abdominal pain occurring in a woman for at least 6 months. Up to a quarter of women are estimated to be affected by CPP worldwide and it is responsible for one fifth of specialist gynecological referrals in the United Kingdom. Psychological interventions are commonly utilized. As waiting times and funding capacity impede access to face-to-face consultations, supported self-management (SSM) has emerged as a viable alternative...

BACKGROUND: Anopheles (Kerteszia) cruzii is the primary vector of human and simian malarias in Brazilian regions covered by the Atlantic Rainforest. Previous studies found that An. cruzii presents high levels of behavioural, chromosomal and molecular polymorphisms, which led to the hypothesis that it may be a complex of cryptic species. Here, An. cruzii specimens were collected in five sites in South-East Brazil located at different altitudes on the inner and coastal slopes of two mountain ranges covered by Atlantic Rainforest, known as Serra do Mar and Serra da Mantiqueria...

Nowadays, the mangrove biome is considered to be a profound resource of natural products usually possessing cytotoxicity of a broader range. Covering the period 2007-2015, a total of 21 new naturally occurring compounds has stood out. For example, xylogranin B and swietephragmin C were found to exhibit very potent cytotoxic activity against the colon HCT-116 cells reaching IC50 values of 0.05 and 0.06 μM, respectively. Bearing in mind the efficacy of the majority compounds in the preliminary in vitro screens, these studies should be expanded to both ex vivo and in vivo screens including the evaluation of the relevant toxicological profiles...

Chondroitin sulfate (Ch) is one of the main structural components of cartilage tissue, therefore, its presence in tissue engineered scaffold is expected to enhance cartilage regeneration. Previously, silk fibroin/chitosan (SF/CS) blend was proven to be a potential biomaterial for tissue development. In this study, the effect of Ch on physicochemical and biological properties of SF/CS blend was investigated and scaffolds with 0.8 wt% Ch was found to be favorable. The scaffolds possess pore size of 37-212 µm, contact angle 46...

Polycystic echinococcosis (PE) is caused by Echinococcus vogeli metacestodes (larval stage) in Neotropical countries. E. vogeli is trophically-transmitted between predators bush dogs (Speothos venaticus) and prey pacas (Cuniculus paca). In Brazil, reported PE cases are restricted to the Amazon biome. In this study, metacestodes from a paca hunted in Mato Grosso do Sul state (Cerrado biome) were identified morphological and histopathological techniques and further confirmed by molecular testing (sequencing of cytochrome C oxidase subunit I (cox1) gene) for the first time...

Transplantation of autologous cultured melanocytes as cell suspension has been used for the treatment of vitiligo. The recipient site is often prepared by laser-mediated dermabrasion. Such procedures encounter disadvantages including prolonged transplantation duration, unsecured cell adherence to lesional skin and potential scarring. To improve this, here we propose a method by preparing recipient sites before transplantation by psoralen and ultraviolet A (PUVA)-induced sunburn followed by transplanting cells with a chitosan-based melanocyte spheroid patch...

Posterior spinal fusion implants include number of interconnecting components, which are subjected to micromotion under physiological loading conditions inducing a potential for fretting corrosion. There is very little known about the fretting corrosion in these devices in terms of the minimum angular displacement (threshold) necessary to induce fretting corrosion or the amount of fretting corrosion that can arise during the life of the implant. Therefore, the first goal was to evaluate the threshold fretting corrosion in three anatomical orientations and second the long-term fretting corrosion for the three different material types of spinal implants under physiological loading conditions...
