A Simple Double-Spin Closed Method for Preparing Platelet-Rich Plasma

Objective: To describe and analyze a new protocol for the extraction of platelet-rich plasma (PRP) for use in clinical practice and compare this technique with methods that have been previously described in the medical literature. Methods: Sixteen blood samples from healthy volunteers were collected. PRP was prepared using our new double-spin technique, consisting of successive centrifugation of blood samples with two different spins, without opening the container. Descriptive analysis of cell counts in baseline and PRP samples was undertaken. Comparison between cell and platelet count in baseline and PRP samples, as well as the statistical analysis, were done. Results: The mean platelet concentration ratio was 3.47 (SD: 0.85; 95% CI: 3.01-3.92; range: 2.48-5.71). The baseline whole blood platelet count correlated positively to the PRP platelet count (rP = 0.56; 95% CI: 0.09- 0.88; P = 0.023). The PRP was enriched for lymphocytes and monocytes but presented significantly lower counts of neutrophils and eosinophils in comparison to baseline. Conclusion: Results show a safe and easily reproducible method to obtain PRP for use in clinical daily practice.info:eu-repo/semantics/publishedVersio

Lattice dynamics localization in low-angle twisted bilayer graphene

A low twist angle between the two stacked crystal networks in bilayer graphene enables self-organized lattice reconstruction with the formation of a periodic domain. This superlattice modulates the vibrational and electronic structures, imposing new rules for electron-phonon coupling and the eventual observation of strong correlation and superconductivity. Direct optical images of the crystal superlattice in reconstructed twisted bilayer graphene are reported here, generated by the inelastic scattering of light in a nano-Raman spectroscope. The observation of the crystallographic structure with visible light is made possible due to lattice dynamics localization, the images resembling spectral variations caused by the presence of strain solitons and topological points. The results are rationalized by a nearly-free-phonon model and electronic calculations that highlight the relevance of solitons and topological points, particularly pronounced for structures with small twist angles. We anticipate our discovery to play a role in understanding Jahn-Teller effects and electronic Cooper pairing, among many other important phonon-related effects, and it may be useful for characterizing devices in the most prominent platform for the field of twistronics.Comment: 9 pages, 8 figure

Applications of the hexanic fraction of Agave sisalana Perrine ex Engelm (Asparagaceae): control of inflammation and pain screening

The present study evaluated the anti-inflammatory and analgesic properties of Agave sisalana Perrine in classic models of inflammation and pain. The hexanic fraction of A. sisalana (HFAS) was obtained by acid hydrolysis followed by hexanic reflux. Anti-inflammatory properties were examined in three acute mouse models (xylene ear oedema, hind paw oedema and pleurisy) and a chronic mouse model (granuloma cotton pellet). The antinociceptive potential was evaluated in chemical (acetic-acid) and thermal (tail-flick and hot-plate test) models of pain. When given orally, HFAS (5, 10, 25 and 50 mg/kg) reduced ear oedema (p < 0.0001; 52%, 71%, 62% and 42%, respectively). HFAS also reduced hind paw oedema at doses of 10 mg/kg and 25 mg/kg (p < 0.05; 42% and 58%, respectively) and pleurisy at doses of 10 mg/kg and 25 mg/kg (41% and 50%, respectively). In a chronic model, HFAS reduced inflammation by 46% and 58% at doses of 10 mg/kg and 25 mg/kg, respectively. Moreover, this fraction showed analgesic properties against the abdominal writhing in an acetic acid model (at doses of 5-25 mg/kg) with inhibitory rates of 24%, 54% and 48%. The HFAS also showed an increased latency time in the hot-plate (23% and 28%) and tail-flick tests (61% and 66%) for the 25 mg/kg and 50 mg/kg doses, respectively. These results suggest that HFAS has anti-inflammatory and analgesic properties.26327

Frequency of sexual dysfunction in women with rheumatic diseases

OBJETIVO: Pesquisar a prevalência de disfunção sexual em mulheres com as seguintes doenças reumáticas: lúpus eritematoso sistêmico, artrite reumatoide, esclerose sistêmica, síndrome antifosfolípide e fibromialgia acompanhados no Ambulatório de Reumatologia do Hospital Universitário de Brasília e do Hospital das Clínicas da Universidade de São Paulo. MÉTODOS: Utilizou-se o índice de função sexual feminina (Female Sexual Function Index - FSfi), questionário que contém 19 itens que avaliam 6 domínios: desejo sexual, excitação sexual, lubrificação vaginal, orgasmo, satisfação sexual e dor. RESULTADOS: Foram avaliadas 163 pacientes. A média de idade foi de 40,4 anos. A prevalência de disfunção sexual foi de 18,4%, porém 24,2% das pacientes não apresentaram atividade sexual nas últimas 4 semanas. Entre os subgrupos, as pacientes com fibromialgia e esclerose sistêmica foram as com maior índice de disfunção sexual (33%). Se excluirmos as pacientes sem atividade sexual, a taxa de disfunção sobe para 24,2%. CONCLUSÃO: A prevalência de disfunção sexual encontrada neste estudo foi menor em relação à literatura. Entretanto, 24,2% das pacientes entrevistadas negaram atividade sexual nas últimas 4 semanas, o que pode ter contribuído para o baixo índice de disfunção sexual.OBJECTIVE: To assess the prevalence of sexual dysfunction in women followed up at the Rheumatology Outpatient Clinic of the Hospital Universitário de Brasília and of the Hospital das Clínicas da Universidade de São Paulo with the following rheumatic diseases: systemic lupus erythematosus; rheumatoid arthritis; systemic sclerosis; antiphospholipid antibody syndrome; and fibromyalgia. METHODS: The Female Sexual Function Index (FSfi), obtained by applying a 19-item questionnaire that assesses six domains (sexual desire, arousal, vaginal lubrication, orgasm, sexual satisfaction and pain), was used. RESULTS: This study assessed 163 patients. The mean age was 40.4 years. The prevalence of sexual dysfunction was 18.4%, but 24.2% of the patients reported no sexual activity over the past 4 weeks. Patients with fibromyalgia and systemic sclerosis had the highest sexual dysfunction index (33%). Excluding patients with no sexual activity, the sexual dysfunction rate reaches 24.2%. CONCLUSION: The prevalence of sexual dysfunction found in this study was lower than that reported in the literature. However, 24.2% of the patients interviewed reported no sexual activity over the past 4 weeks, which might have contributed to the low sexual dysfunction index found

Tuberculose abdominal de apresentação atípica acometendo próstata e fígado, com disseminação miliar pulmonar: relato de caso / abdominal tuberculosis of atypical presentation accompeting prostate and phygum, with pulmonary mile dissemination: case report

A tuberculose tem como principais órgãos acometidos os pulmões, com o comprometimento abdominal ocorrendo em cerca de 12% dos pacientes com acometimento extrapulmonar (pleural e ganglionar são os mais frequentes). A forma abdominal pode envolver diversas estruturas, como os tratos gastrintestinal e geniturinário, fígado, baço, pâncreas, peritônio e linfonodos, afetando órgãos sólidos em cerca de 10% dos casos, com o comprometimento hepático ocorrendo em menos de 1% de todas as infecções tuberculosas. Este trabalho tem como objetivo apresentar um caso raro de tuberculose macronodular no fígado e próstata, com apresentação radiológica atípica pseudotumoral, em um paciente com tuberculose miliar pulmonar. 

A list of land plants of Parque Nacional do Caparaó, Brazil, highlights the presence of sampling gaps within this protected area

Brazilian protected areas are essential for plant conservation in the Atlantic Forest domain, one of the 36 global biodiversity hotspots. A major challenge for improving conservation actions is to know the plant richness, protected by these areas. Online databases offer an accessible way to build plant species lists and to provide relevant information about biodiversity. A list of land plants of “Parque Nacional do Caparaó” (PNC) was previously built using online databases and published on the website "Catálogo de Plantas das Unidades de Conservação do Brasil." Here, we provide and discuss additional information about plant species richness, endemism and conservation in the PNC that could not be included in the List. We documented 1,791 species of land plants as occurring in PNC, of which 63 are cited as threatened (CR, EN or VU) by the Brazilian National Red List, seven as data deficient (DD) and five as priorities for conservation. Fifity-one species were possible new ocurrences for ES and MG states
