Quantification and validation (MRM) of analysis - compounds isolated from Heteropterys umbellata (Malpighiaceae)

ABSTRACT: Analyses of Heteropterys umbellata (Malpighiaceae) stems and leaves extracts. Plants were collected in two different Brazilian States (Sao Paulo and Minas Gerais). Dried plant material was extracted with EtOH80%. Positive ionization mode analyses. LC-MS/MS analyses were performed in a Shimadzu HPLC using a Phenomenex C18-Luna (250 mm x 4.6 mm, 5.0 um) column and an Amazon SL (Bruker Daltonics) mass spectrometer (ion trap) equipped with an ESI source. Multiple reaction monitoring (MRM) mode for quantification of isolated compounds. The transitions 499.10->319.10, 501.10->365.10, 602.20->466.10, and 296.10->278.00 were chosen to monitor 3,5-di-O-caffeoylquinic acid (isochlorogenic acid A); 1,2,6-tris-O-[3-nitropropanoyl]-beta-glucopyranose (karakin); 1,2,3,6-tetrakis-O-[3-nitropropanoyl]-beta-glucopyranose; and sodium diclofenac (used as internal standard), respectively.

SP80-3280 growth and maturation field 2

Project description:A field experiment was conducted at the Agricultural Sciences Center of the Federal University of Sao Carlos in Araras (22'21'25'S and 47'23'3'W) in the state of Sao Paulo, Brazil. Trial plots of SP-3280 consisted of four rows of 10 m long and spaced 1.35m apart. The field experiment was initiated in October 2012 and extended up until November 2013, representing the conditions under which ?one-year? sugarcane crops are cultivated.

Gene expression data from Brazilian SPAH study

Project description:This study is part of previous epidemiologic project, including a population-based survey (Sao Paulo Ageing & Health study (SPAH Study). The data from this study was collected between 2015 to 2016 and involved elderly women (ages ≥65 yeas) living in the Butanta district, Sao Paulo. The purpose of the study was identification of association between transcriptome and the osteo metabolism diseases phenotype, like osteoporosis, vertebral fracture and coronary calcification. Peripheral blood cells suffer alterations in the gene expression pattern in response to perturbations caused by calcium metabolism diseases. The purpose of this study is to identify possible molecular markers associated with osteoporosis, vertebral fractures and coronary calcification in elderly women from community from Brazilian SPAH study. Vertebral fractures were the most common clinical manifestation of osteoporosis and coronary calcifications were associated with high morbimortality.

Diffuse Alveolar Damage Patterns Reflect the Immunological and Molecular Heterogeneity in Fatal COVID-19

Project description:To date, few studies analyzed the nature of the temporal and spatial cell arrangement during the complex immune/inflammatory/molecular and structural cell alterations that take place in the lungs in severe COVID-19. Such information is crucial to better envision the disease complexity. To this end, we have applied a platform for multiplex imaging complemented with assessment of SARS-CoV-2, bacterial/fungi identification and cytokine/transcriptomic profiling in 18 lungs of deceased patients from Sao Paulo.

Transcription profiling of lymph node from mice with collagen induced arthritis in response to the endothelin receptor antagonist Bosentan

Project description:DBA/1J mice (12 wk old; weighing 18-22 g) were housed in temperature-controlled rooms (22-25 C) in the animal facility of the School of Medicine of Ribeir o Preto, University of Sao Paulo, Sao Paulo, Brazil, and received water and food ad libitum. Male DBA/1J mice received 200 g of bovine type II collagen (CII) in CFA by intradermal injection (day 0). Collagen (200 ?g in PBS) was given again on day 21 by i.p. injection. Mice were monitored daily for signs of arthritis for which severity scores were derived as follows: 0=normal, 1=erythema, 2=erythema plus swelling, 3= extension/loss function and total score = sum of four limbs. Disease onset characterized by erythema and/or paw swelling was seen between days 25 and 35. For the therapeutic approach, DBA/1 mice were treated with Bosentan (100 mg kg-1) p.o. or vehicle once a day for a total of 11 days. The treatment began on day that CIA became clinically detectable. The DBA-1/J mice were sacrificed preferentially by CO2 inhalation, and the lymph nodes removed. To obtain sufficient mRNA for hybridization to the glass slides, total inguinal lymph nodes RNA was pooled from three mice at each time point (2 inguinal lymph nodes per mouse). Total RNA samples were prepared using Trizol® reagent according to the manufacturers instructions. Undegraded and DNA-, protein- and phenol-free RNA preparations were verified by classic agarose gel electrophoresis stained with ethidium bromide and ultraviolet spectrophotometry, respectively.
