Anti-inflammatory choline based ionic liquids: Insights into their lipophilicity, solubility and toxicity parametrites

The impact on in vivo efficacy and safety of two novel ionic liquids based on the association of choline with nonsteroidal anti-inflammatory drugs, ketoprofen and naproxen forming IL-APIs, was evaluated. Their lipophilicity, solubility and toxicity were assessed aiming the illustration of the pharmaceutical profile and potential toxic impact. Partition coefficientwas determined usingmicelles of hexadecylphosphocholine and UV–Vis derivative spectroscopy. Additionally, solubility in phosphate buffer pH 7.4 wasmeasured using amodified shake flaskmethod and UV–Vis spectroscopy as detection technique. Ultimately, toxicity was considered resorting to a fully automated cytochrome c oxidase assay based onmicrofluidics. The obtained results demonstrated that the IL-APIs' drug format has the ability to interact with biological membranes and also improves solubility up to 58 times. Moreover, it was evidenced that, although being a nutrient, choline influences the IL-APIs' toxicity. The studied anti-inflammatory IL-APIs exhibited promising properties regarding their incorporation in pharmaceutical formulations

The Advertisement Calls and Distribution of Two Sympatric Species of \u3cem\u3eChiasmocleis\u3c/em\u3e (Méhely 1904) (Anura, Microhylidae, Gastrophryninae) from the Atlantic Forest

The advertisement calls of Chiasmocleis cordeiroi and C. crucis are described for populations from the municipalities of Igrapiúna and Camacan, respectively, state of Bahia, Brazil. Both calls consist of multipulsed notes produced in series. Differences between the two calls are: dominant frequency, higher in C. cordeiroi (range 4500-4898 Hz; C. crucis range 4069-4435 Hz); note rate, higher in C. cordeiroi (range 6.20--7.46 s/note; C. crucis range 5.17-5.59 s/note); pulse rate, higher in C. cordeiroi (151.82-194.83 s/note; C. crucis range 125.30- 142.12 s/note); and the structure of the modulation patterns of the notes. Moreover, the advertisement calls of C. crucis and C. cordeiroi are more similar than the calls of all syntopic congeners. Furthermore, the current distribution of both species was extended

Photosynthesis, stomatal conductance and leaf water potential in crabwood (Carapa guianensis)

Leaf water potential is one of the most important factors affecting stomatal functioning. The aim of this study was to assess the effect of variation in diurnal irradiance and vapour pressure deficit on photosynthesis (A), stomatal conductance (g s) and leaf water potential (psi) in Carapa guianensis (Aubl.). Data were collected from 07:00 to 17:00 h. Photosynthetic rates reached a maximum (2.5 µmol m-2 s-1) at 10:00 h, thereafter declined to a minimum of 1 µmol m-2 s-1 at 16:00 h. Stomatal conductance oscillated during the day, from 0.04 mol m-2 s-1 (at midday) to 0.02.mol.m-2.s-1 at the end of the afternoon. Leaf water potential was higher early in the morning (-0.3 MPa) and lower (-0.75 MPa) at mid-afternoon (14:30 -15:00 h). After reaching a minimum, psi increased up to -0.64 MPa at sunset. Photosynthetic rates increased linearly as a function of g s (P < 0.01). Also there was a positive relationship between psi and g s (P< 0.01). Photosynthetic rates declined during the day after reaching a peak early in the morning, which makes clear that environmental factors that influence psi greatly affect carbon assimilation of C. guianensis.O potencial hídrico da folha é um dos fatores mais importantes que afetam o funcionamento dos estômatos. O objetivo deste trabalho foi avaliar o efeito da variação diurna na irradiância e déficit de pressão de vapor (DPV) na fotossíntese (A), condutância estomática (g s) e potencial hídrico da folha (psi) em Carapa guianensis (Aubl.). Os dados foram coletados de 07:00 às 17:00 h. A taxa fotossintética atingiu um valor máximo (2,5 µmol m-2 s-1) às 10:00 h, depois declinou até atingir um mínimo de 1 µmolm-2 s-1 às 16:00 h. A condutância estomática oscilou durante o dia, de 0,04 molm-2s-1 (ao meio dia) para 0,02 molm-2s- 1 no final da tarde. O potencial hídrico da folha foi máximo nas primeiras horas do dia (-0,3 MPa) e mínimo (-0,75 MPa) no meio da tarde (14:30 a 15:00 h). Após ter alcançado um mínimo, o psi aumentou até -0,64 MPa no fim da tarde. A taxa fotossintética aumentou linearmente em função do g s (P < 0,01). Também houve uma relação positiva entre psi e g s (P < 0,01). A taxa fotossintética declinou durante o dia após ter alcançado um pico no início da manhã, demonstrando que os fatores ambientais que afetam o psi têm efeito significativo na assimilação do carbono de C. guianensis

Parâmetros hematológicos de jumentas gestantes em diferentes períodos

The hematological parameters and total protein concentration in healthy donkeys during pregnancy, under grass handling conditions in tropical weather, were evaluated. Fifth-two Marchador Brasileiro breed healthy donkeys, ranging from 8 to 16 years old, were evaluated, 36 of which were pregnant. The animals were separated in four groups: non pregnant (control), pregnancy from 25 to 110 days (first phase), from 111 to 210 days (second phase), and from 211 to 340 days (third phase). Total protein, erythrocyte, and leukocytes counts; packed cell volume; hemoglobin concentration; hematimetric absolute rates of mean corpuscular volume (MCV); mean corpuscular hemoglobin (MCH); and mean corpuscular hemoglobin concentration (MCHC) were evaluated. Total protein and eosinophils count decreased in the first phase. Red blood cells, hemoglobin concentration, and MCHC increased in the third phase of pregnancy. However, MCV and MCH decreased in the same phase

Diary of the journals: the everyday of sensitive writing in the shared formation in health

Neste relato de experiência apontamos a polifonia produzida com a escrita de diários de campo na formação do profissional da saúde. Com base no trabalho de campo vivido por professores e estudantes da Universidade Federal de São Paulo, no campus Baixada Santista (Unifesp-BS), São Paulo - Brasil, destacamos a importância da escrita sensível na elaboração das experiências vividas e as possibilidades que esta assume na formação. Os encontros aconteceram semanalmente durante um semestre no módulo - Eixo de Trabalho em Saúde, que integra o projeto político-pedagógico do campus na experiência interdisciplinar. A partir do método cartográfico e uma escrita a muitas mãos, o relato mistura reflexões teóricas e trechos de diários, criando um mapa de afetos sobre a experiência vivida, dando visibilidade a pontos de intensidades que se desdobram em reflexões para as áreas da saúde, artes e educação.23In this experience report, we pointed out the polyphony produced with the writing of field diaries in the health professional education.
