Intermolecular interactions of the malate synthase of Paracoccidioides spp

Background: The fungus Paracoccidioides spp is the agent of paracoccidioidomycosis (PCM), a pulmonary mycosis acquired by the inhalation of fungal propagules. Paracoccidioides malate synthase (PbMLS) is important in the infectious process of Paracoccidioides spp because the transcript is up-regulated during the transition from mycelium to yeast and in yeast cells during phagocytosis by murine macrophages. In addition, PbMLS acts as an adhesin in Paracoccidioides spp. The evidence for the multifunctionality of PbMLS indicates that it could interact with other proteins from the fungus and host. The objective of this study was to identify and analyze proteins that possibly bind to PbMLS (PbMLS-interacting proteins) because protein interactions are intrinsic to cell processes, and it might be possible to infer the function of a protein through the identification of its ligands. Results: The search for interactions was performed using an in vivo assay with a two-hybrid library constructed in S. cerevisiae; the transcripts were sequenced and identified. In addition, an in vitro assay using pull-down GST methodology with different protein extracts (yeast, mycelium, yeast-secreted proteins and macrophage) was performed, and the resulting interactions were identified by mass spectrometry (MS). Some of the protein interactions were confirmed by Far-Western blotting using specific antibodies, and the interaction of PbMLS with macrophages was validated by indirect immunofluorescence and confocal microscopy. In silico analysis using molecular modeling, dynamics and docking identified the amino acids that were involved in the interactions between PbMLS and PbMLS-interacting proteins. Finally, the interactions were visualized graphically using Osprey software. Conclusion: These observations indicate that PbMLS interacts with proteins that are in different functional categories, such as cellular transport, protein biosynthesis, modification and degradation of proteins and signal transduction. These data suggest that PbMLS could play different roles in the fungal cell. © 2013 de Oliveira et al.; licensee BioMed Central Ltd.

Modelo de Marcus, elementos de matriz de tunelamento, efeitos de solvente e controle nuclear em reações de transferência de elétrons

This paper aims to give an initial presentation to physics students of the area of electron transfer, addressing its major aspects. The subject is then presented in an introductory way, highlighting and discussing the key points. Primarily, the problem is approached in a simplified manner through a two-state system, and aspects of calculating the matrix-element are discussed. Then, the electron transfer problem, influenced by nuclear reaction coordinates, is addressed and treated by the Marcus theory. Time scales and the concepts of adiabatic and nonadiabatic phenomena are discussed in the context of electron transfer. The classical, semi-classical and quantum formalisms of for the nuclear reactions coordinates are presented, and aspects of solvents are also discussed. Finally, we conclude by examining some recent examples of problems discussed in the literature.

Fisioterapia Aquática na Transferência do Sentado para Ortostatismo no Paciente com AVC: Relato de Caso

Introduction. Studies show that 70% of body weight in patients with stroke during the transfer from sitting to standing position is transferred to the uninvolved limb. Significantly interfering with activities of daily living. Objective. The influence of aquatic therapy on eight in the affected hemisphere during the transition from sitting to standing. Method. Participated in this study a patient with right hemiparesis, the protocol lasted eight sessions in a liquid medium. The data of activation of the gluteus muscle were collected from surface electromyography and data as the weight transfer was examined by baropodometry platform. Results. Initial electromyography (151.1uv right gluteus maximus and left gluteus maximus 229.1uv) and Final electromyography (113.6 uv right gluteus maximus and left gluteus maximus113.3uv). Evolution was 19% in weight transferin paretic hemibody compared the pre and post intervention. Conclusion. The results showed that treatment was favorable to the patient, because at the end of application of the observed activation of the gluteus maximus and improved weight-bearing, and consequently these factors interfered positively in the security and independe in transferring from sitting to standing position.
