Partial purification of trypsin/papain inhibitors from Hymenaea courbaril L. seeds and antibacterial effect of protein fractions

Abstract: The crude extract and protein fractions of Hymenaea courbaril L. seeds were investigated for the presence of trypsin and papain inhibitors and antimicrobial activity against Vibrio parahaemolyticus, Staphylococcus aureus, and Escherichia coli. Protein fractions were obtained from the crude extract after precipitation with ammonium sulfate into three saturation ranges (0-30%, 30-60%, and 60-90%), called Hc030, Hc3060, and Hc6090, respectively. The crude extract and protein fractions inhibited trypsin and papain activity, but to different degrees. Antimicrobial activity was observed in Hc030 and Hc3060 fractions, but only against V. parahaemolyticus.The inhibitor isolated from the Hc3060 fraction was more effective in inhibiting trypsin (100% inhibition) than papain (54% inhibition), and showed an apparent molecular mass of 20 kDa. This study shows that H. courbaril seeds contain proteins with protease-inhibiting and antibacterial activity, indicating that this species is a source of bioactive compounds.

Miscellaneous Diterpenes from the Aerial Parts of Plectranthus ornatus Codd

Abstract: Five new diterpenes derivatives named as ornatin A, B, C, D and E, in addition to six known related diterpenes were isolated from the aerial parts of cultivated specimens of Plectranthus ornatus. The structures were elucidated using a combination of 1D/2D nuclear magnetic resonance (NMR) spectroscopy, high-resolution electrospray ionization mass spectrometry (HRESIMS) and comparison with published NMR data of analogous compounds. All isolated compounds were assayed against four human cancer cell lines, and Gram-positive and Gram-negative bacteria strains. None of them showed any cytotoxic activity, but ornatin C, D, E and three related diterpenes displayed marginal bactericidal or bacteriostatic effects against the Gram-positive strains.

Células da geleia de Wharton do cordão umbilical ovino mantidas em diferentes meios de cultivo são permissivas à infecção in vitro por lentivírus de pequenos ruminantes

Abstract: O objetivo deste estudo foi isolar celulas da geleia de Wharton do cordao umbilical (GWCU) ovino coletado por ocasiao do parto natural, utilizando-se diferentes meios de cultivo, alem de relatar, pela primeira vez, sua permissividade a infeccao in vitro por lentivirus de pequenos ruminantes (LVPRs). Dez cordoes umbilicais foram coletados de ovelhas higidas e soronegativas para LVPRs pelo teste de imunodifusao em gel de agarose (IDGA). De cada cordao, explantes foram cultivados em quatro meios distintos que consistiram em MEM, DMEM baixa glicose, meio 199 e RPMI-1640, todos acrescidos de 10% de soro fetal bovino em estufa com atmosfera umida e 5% de CO2 a 37oC. A permissividade de infeccao das celulas GWCU ovino foi testada frente as cepas CAEV-Cork e MVV-K1514, inoculando-se 0,1 MOI de cada cepa viral e corando as monocamadas com May Grunwald Giemsa para visualizacao do efeito citopatico. Foram obtidos quatro sobrenadantes CAEV-Cork e quatro MVV-K1514, provenientes do cultivo de celulas GWCU ovino infectadas por 21 dias em meios distintos, dos quais foram realizadas titulacao em membrana sinovial caprina e extracao do DNA pro-viral para realizacao de nested-PCR e eletroforese em gel de agarose a 2%. Os resultados demonstraram a presenca de efeito citopatico na infeccao in vitro tanto por CAEV-Cork como por MVV-K1514 em todos os meios de cultivo, sendo visualizados sincicios e lise celular em microscopio invertido. A nested-PCR detectou o DNA pro-viral tanto do CAEV-Cork como do MVV-K1514 em todos os sobrenadantes. Os sobrenadantes contendo o virus CAEV-Cork apresentaram titulos em TCID50/mL de 105,5 em MEM, 104,0 em DMEM baixa glicose, 105,0 em meio 199 e 105,7 em RPMI-1640. Os sobrenadantes contendo o virus MVV-K1514 apresentaram titulo em TCID50/mL de 104,3 em MEM, 103,5 em DMEM baixa glicose, 104,7 em meio 199 e 103,5 em RPMI-1640. Celulas GWCU ovino sao permissivas a infeccao in vitro pelos lentivirus de pequenos ruminantes CAEV-Cork e MVV-K1514.

Unregulated health care workers in the care of aging populations: Similarities and differences between Brazil and Canada

Abstract: Introduction The world’s population is rapidly aging. Unregulated health care workers (UHCWs) are emerging as a potentially important workforce in the care of older adults. Objective A review was conducted to identify the activities of UHCWs with respect to contributions and limitations. Methods A systematic integrative literature review was conducted using online databases (LILACS, PubMed, EMBASE, CINAHL, and grey literature). The inclusion criteria were as follows: (i) description of UHCW activities related to older adults; and (ii) description of UHCW activities performed in Brazil or Canada. Results Eleven papers were included in this review. In both countries, UHCW activities included health promotion, mental health care, and rehabilitation. In Brazil, UHCWs performed integrated care, while in Canada UHCWs performed personal care and housekeeping. Conclusion These results highlight the potential and limits of UHCWs who provide care for the aging population. Such information is important to health and social policy making and household decision making.

Caldo de cana desidratado na ração de codornas de corte

Abstract: The objective of this work was to evaluate the effect of dehydrated cane juice (DCJ) on the performance, carcass quality, and economic index of European quails ( Coturnix coturnix), during the period from 22 to 42 days of age. One hundred and ninety-two quails with 22 days of age were distributed in a completely randomized design, with four treatments and six replicates of eight birds each. DCJ was added at 0, 1.5, 3.0, and 4.5% in the feed. The economic feasibility of including DCJ levels in the feed was evaluated through relative gross margin. In the period from 29 to 35 days of age, there was increased linear effect of feed intake with the increase of DCJ in the feed. However, there was a quadratic effect of DCJ levels on carcass, drumstick+thigh, and abdominal fat weights, and the estimated optimum levels were 1.69, 2.50, and 2.34%, respectively. There was a decreasing linear effect of DCJ levels on breast weight with and without skin. Economic analysis showed higher profits to the producer with the use of conventional feed. However, among the DCJ levels of inclusion, the level of 1.5% showed the best results, with a difference of 0.47% in relative gross margin when compared to the conventional feed. The addition of 1.69 and 2.50% of dehydrated cane juice in the feed is recommended to achieve higher carcass and drumstick+thigh weights in meat quails, respectively.

Síntese e caracterização de surfactantes alquilfenil poliglicosídicos a partir da amilose e alquil fenóis extraídos do LCC natural

Abstract: The surfactants were synthesized by condensing the obtained oligosaccharides of amylose and alkyl phenols extracted from the natural cashew nut shell liquid (nCNSL). The Nuclear Magnetic Resonance (NMR) and Fourier Transform Infrared Spectroscopy (FTIR) data showed aromatic ring bands, glycosidic rings, olefins and paraffins. The Nuclear Overhauser Effect Spectroscopy (NOESY) experiments showed that the conformation of the glycosidic units is of the type 4C1 with an α anomeric configuration. The values of Gibbs free energy of micellization (ΔGomic) indicate that the spontaneity of formed micelles are cardanyl oligoglycosides > cardyl oligoglycosides > anacardyl oligoglycosides. The surface tension (γ) measurements showed that critical micelle concentration (cmc) values were low for surfactants. The study γ versus lnc (g dm-3) indicated that the aggregation behavior of the surfactants is dependent on their structural characteristics, as well as their thermal behavior. The area per molecule (A) values indicates that cardyl oligoglycosides are likely to form aggregates smaller than cardanyl oligoglycosides and anacardyl oligoglycosides. The critical packing parameter (cpp) indicates that the aggregates are of the vesicles and bilayers.
