Objective Our objective was to describe the postgraduate education trajectories of family and community physicians in Brazil,where neither primary healthcare nor family and community medicine is recognised as a knowledge area for the purpose of research and postgraduate education(master’s and PhD degrees).design An observational,exploratory study,using administrative data.A nationwide list of family and community physicians as of late November 2018 was compiled from multiple *** on the mode of specialisation was obtained from the same sources and were correlated with data on master’s and PhD degrees,obtained from the curricula vitae on the Lattes *** This study was set in *** 6238 family and community physicians(58.3%female),of whom 2795 had earned a specialist certificate(identified from the list of physicians certified by Sociedade Brasileira de Medicina de Família e Comunidade)and 3957 had completed medical residency(identified from SisCNRM,the national information system for medical residency).Results A master’s degree was held by 747(12.0%)family and community physicians,and a PhD by 170(2.7%);most degrees were in collective health(47.0%and 42%,respectively).Men were more likely than women to hold a master’s degree(adjusted odds ratio(aOR)1.24,95%uncertainty interval(UI)1.07-1.45)and even more likely to a hold PhD(aOR 1.86,95%UI 1.35-2.59).Family and community physicians were also less likely to hold a PhD degree if their master’s degree was professional(oriented towards jobs outside academia)instead of academic(aOR 0.15,95%UI 0.05-0.39)or in some area other than collective health or medicine(aOR 0.41,95%UI 0.21-0.78,compared with a master’s degree in collective health).The postgraduate degree was more likely to precede specialisation for family and community physicians specialising through certification(master’s degree 39.9%,PhD 33%)than through medical residency(master’s degree 9.1%,PhD 6%).Conclusion Family and community

Rheumatoid arthritis （RA） is a chronic inflammatory disease characterized by synovial joint inflammation and cartilage and bone tissue destruction. Although there exist some treatment strategies for RA, they are not completely safe and effective. Therefore, it is important to develop and test new drugs for RA that specifically target inflamed/swollen joints and simultaneously attenuate other possible damages to healthy tissues. Nanotechnology can be a good alternative to consider when envisioning predse medication for treating RA. Through the use of nanopartides, it is possible to increase bioavailability and bioactivity of therapeutics and enable selective targeting to damaged joints. Herein, recent studies using nanoparticles for the treatment of RA, namely with liposomes, polymeric nanoparticles, dendrimers, and metallic nanoparticles, have been reviewed. These therapeutic strategies have shown great promise in improving the treatment over that by traditional drugs. The results of these studies confirm that feasibility of the use of nanopartides is mainly due to their biocompatibility, low toxicity, controlled release, and selective drug delivery to inflamed tissues in animal RA models. Therefore, it is possible to claim that nanotechnology will, in the near future, play a crucial role in advanced treatments and patient-specific therapies for human diseases such as RA.

Fungal endophytic species inhabiting the leaves of eucalypts are capable of utilising leaf sugars and can influence both plant growth and health. Endophytic fungal symbionts can use simple soluble sugars in leaves as their main carbon source. This study set out to determine the diversity and distribution of the endophytic filamentous fungal leaf community in the hybrid Eucalyptus urograndis due to its economic importance. The fungal leaf community was characterised using denaturing gradient electrophoresis (DGGE) and correlated with levels of leaf nutrients and sugars throughout plant development. Sequencing of DGGE bands revealed the presence of Basidiomycota and Ascomycota phyla. Fourteen species and three genera of filamentous fungi were identified, and the population structure was affected by the plant developmental stage. Levels of K, Cu, N and Mn influenced communities from the clonal garden, whereas leaves in the field had higher glucose, fructose and sucrose. Many fungi were found to be specific to a certain development stages: Diplomitoporus crustulinus, Podosphaera tridactyla and Aspergillus restrictus to the clonal garden stage;Chaetomella acutiseta and Ascotricha chartarum to the shading stage;Erratomyces patelii and Saxomyces sp. to the shading output stage;Lepidostroma sp. and Saxomyces sp. to the dispatch stage;and Mycosphaerella populicola to the field stage. Teratosphaeria toledana and Teratosphaeria acidotherma were found at more than one developmental stage. Cladosporium sp. and Rhodosporidium fluviale colonized and persisted in plants at the dispatch and field stages. This is the first report of P. tridactyla, A. restrictus, E. patelii, Saxomyces and Lepidostroma sp. as endophytes in eucalipt.
