1. Mercury Concentration in Liver Tissues of South American Fur Seals (Arctocephalus australis) from Southwestern Atlantic Ocean
Mercury (Hg) contamination of oceans is rapidly increasing, however Hg bioaccumulation in pinnipeds has been understudied. Here, we report for the first time Hg concentration in liver tissues of South American fur seals (Arctocephalus australis) in South and Southeast Brazil. Hg concentration was determined in twenty-five fur seals’ specimens found strande

2. Bioprosthetic Aortic Valve Degeneration: a Review from a Basic Science Perspective
Abstract Introduction: The increase in the prevalence of aortic stenosis due to an aging population has led to an increasing number of surgical aortic valve replacements. Over the past 20 years, there has been a major shift in preference from mechanical to bioprosthetic valves. However, despite efforts, there is still no "ideal" bioprosthesis. It is crucial

3. What is new in non-chromatographic flavonoid purification?
Flavonoids are metabolites occurring in all plant tissues and present different biological activities. They occur in a mixture of similar polarity with laborious separation and purification processes, usually furnishing low yields. Semi-preparative chromatographic methods are universally employed procedures for their isolation. This paper discusses the state

5. Fat grafting associated with negative pressure wound therapy
Abstract Purpose: To describe a case report of FG associated with NPWT in the treatment of complex wound on the distal third of the lower limb with bone exposure. Case Report: A 59-year-old patient with chronic left tibial osteomyelitis since childhood underwent extensive debridement of the distal tibial diaphysis (40% of bone thickness per 10 cm extension

6. Investigation of the effect of nozzle design on rheological bioprinting properties using computational fluid dynamics
ABSTRACT Bioprinting is the utilization of techniques derived from three-dimensional printing to generate complex biological structures which may replace natural tissues or organs. It employs high spatial resolution deposition of different cell types, growth factors and biomaterials. Those together form bioinks, which are the bioprinting inputs, analogously

7. Updating the role of matrix metalloproteinases in mineralized tissue and related diseases
Abstract Bone development and healing processes involve a complex cascade of biological events requiring well-orchestrated synergism with bone cells, growth factors, and other trophic signaling molecules and cellular structures. Beyond health processes, MMPs play several key roles in the installation of heart and blood vessel related diseases and cancer, ran

8. [PROVISIONAL] Identification of histone methylation modifiers and their expression patterns during somatic embryogenesis in Hevea brasiliensis
Abstract Histone methylation plays a crucial role in various biological processes including from heterochromatin formation to transcriptional regulation. Currently, no information is available regarding histone methylation modifiers in the important rubber-producing plant Hevea brasiliensis. Here, we identified 47 histone methyltransferase (HMT) genes and 25

9. Treatment of Resorbed Mandibles with Titanium Plate and Immediate Implant-Supported Prosthesis - Case Series
Resumo Mandíbulas severamente reabsorvidas com apenas osso cortical remanescente podem fraturar durante ou após a colocação de implantes. O presente relato de casos apresenta uma técnica para reduzir o risco ou as consequências da fratura mandibular. Pacientes com apenas osso cortical remanescente foram tratados com a fixação de placa de titânio na

10. DNA de alta qualidade isolado a partir do córtex de Euterpe edulis Mart. (Arecaceae)
Resumo Euterpe edulis (palmiteiro-juçara) é uma arbórea de porte alto que ocorre naturalmente em florestas da Mata Atlântica e Cerrado. Por estas características é difícil coletar folhas jovens, sadias e frescas para obtenção de DNA genômico de boa qualidade para a espécie, necessárias para estudos de biologia molecular. Visando facilitar coletas

11. Effect of low power laser in biomodulation of cultured osteoblastic cells of Wistar rats
Abstract Purpose: To analyze aspects of the biomodulating effect of light in biological tissues, bone cells from surgical explants of the femur of rats were irradiated with low intensity laser. Methods: Bone cells were cultured and irradiated with LASER light (GaAlAs). Growth, cell viability, mineralized matrix formation, total protein dosage, immunostim

12. NANOTOXICOLOGIA DE NANOPARTÍCULAS DE PRATA: TOXICIDADE EM ANIMAIS E HUMANOS
Silver nanoparticles (AgNPs) have important antimicrobial activity. These nanoparticles are present in several commercial products, leading to human and environmental exposure. This review presents a critical view of the toxic effects of Ag NPs on in vitro and in vivo biological models. It is noteworthy that the toxicity of AgNPs is dependent on several para
