Abstract:
The determination of Cd, Co, Cr, Cu, Fe, Na, Zn, and Pb by inductively coupled plasma-optical emission spectrometry (ICP OES) was performed on dry matter and decoctions of the medicinal plants Cordia salicifolia, Chiococca alba (L.) Hitchc., and Echites peltata used as an appetite suppressant and diuretic in Brazil. The accuracy of the measurements was analyzed by the spike recovery test. Results showed that the concentration of these seven metals (Cd, Co, Cr, Cu, Fe, Na, and Zn) in dry plant samples is below the oral concentration of elemental impurities established by the United States Pharmacopoeia Convention (USP). However, there are no concentration limits for Fe, Na, and Zn established by the USP in drug substances and excipients. Levels higher than the recommended value by the USP were observed for Pb and the lowest for Cd, Co, Cr, and Cu, both in dried plant samples and their decoctions. In the decoctions prepared from these plants were found elements such as Cd, Co, Cr, Cu, Fe, Na, Zn, and Pb. In the decoction prepared from 40 g C. salicifolia leaves and 40 g C. alba wood, the content of Cd is above the oral daily exposure value set by the USP. Hazard index (HI) for decoctions prepared from these plants exceeded the threshold (1). Given the uncertainties associated with the estimates of toxicity values and exposure factors, futures researches should address the possible toxicity in humans. Uncontrolled selling and long-term ingestion of medicinal plants can cause toxicity and interfere with the effect of drugs. Limited knowledge on the interaction potential of medicinal plants poses a challenge and public health problem in Brazil and other countries.

Abstract:
Antecedentes y Objetivos: Se presenta el primer listado florístico de las playas y dunas costeras de México, actualizado y respaldado por ejemplares de herbario.Métodos: Se revisaron 14 herbarios nacionales y extranjeros. Se sobrepuso una retícula de 2 × 2 km al mapa de la costa y de las dunas costeras de México para referir todos los registros que corresponden a 2180 sitios con 12,419 ejemplares de plantas. Se calcularon índices de diversidad, similitud, diversidad taxonómica y redundancia.Resultados clave: La flora registrada consta de 153 familias, 897 géneros y 2075 especies de plantas vasculares, las cuales representan 9.5% de la flora vascular de México. Las cinco colecciones con índices de redundancia altos IR≥0.7 son los herbarios de la Universidad Nacional Autónoma de México (MEXU, IR=0.9), del Centro de Investigación Científicas de Yucatán (CICY, IR=0.8), y los del Centro de Investigaciones Biológicas del Noroeste (HCIB), el Instituto de Ecología, A.C. (XAL) y el del Museo de Historia Natural de San Diego (SD), cada uno con un IR de 0.7. Se reconocen cinco regiones florísticas que corresponden a los mares de México. El Pacífico Norte tiene mayor diversidad taxonómica y el Pacífico Sur menor diversidad taxonómica. El Golfo de California, Golfo de México y Mar Caribe tienen diversidades taxonómicas similares. Las especies con más registros son Trianthema portulacastrum (165), Croton punctatus (107), Echites umbelllatus (106) e Ipomoea pes-caprae (90). Por el carácter de ecotono de las dunas costeras, la mayoría de las especies se comparten con los tipos de vegetación vecinos (selvas, matorrales, y humedales como las marismas y manglares).Conclusiones: Esta primera lista de la flora en playas y dunas de México es la base para múltiples estudios florísticos regionales y locales, biogeográficos, y ecológicos; además, que será importante para su uso en temas de impacto ambiental y manejo costero.

Abstract:
The precise structure of the adult Drosophila eye results from a coordinated process of cell sorting, differentiation and selective cell death in the retinal epithelium. Mutations in the gene echinus cause supernumerary pigment cells due to insufficient cell death. This study reports the identification of echinus and the characterization of its role in Drosophila retinal development. Using a combination of deletion mapping, gene expression analysis and genomic sequencing, echinus was cloned and several alleles were sequenced. echinus encodes a ~180kDa protein containing an ubiquitin hydrolase domain at its N-terminus and a polyglutamine tract at its C-terminus. echinus is expressed in the retina during pupal development and mutants of echinus have decreased levels of apoptosis during several stages of retinal development. Defects in the cell sorting process that precedes cell death are also observed in echinus loss-of-function mutants and echinus overexpression can cause defects in ommatidial rotation and the morphology of cone cells. echinus is a positive regulator of DE-cadherin and Enabled accumulation in adherens junctions of retinal epithelial cells. Genetic interactions were observed between echinus and the genes wingless, enabled and expanded. An immunofluorescence assay in Drosophila S2 cell cultured demonstrated that Echinus localizes to intracellular vesicles that do not appear to be endocytic in nature, and the C-terminal region of Echinus was shown to be necessary for this association. A protein interaction screen using an immunoprecipitation and mass spectrometry approach identified interactions between Echinus and the vesicle coat protein Clathrin, the scaffolding protein RACK1 and the casein kinase I epsilon (Dco). Co-immunoprecipitation additionally identified an interaction between Echinus and Enabled. This work has revealed echinus to be an important regulator of cell sorting and adherens junction formation in the developing retina and has identified multiple interactions between echinus and enabled, a regulator of the actin cytoskeleton.

Abstract:
Several authors have shown that antithrombin III (AT III) was catalytically inactivated by neutrophil elastase, an observation relevant to pathophysiological processes in the vicinity of inflammatory sites. The aim of this study was to investigate whether HC II, another natural thrombin inhibitor, is also inactivated by PMNL.A rapid loss of HC II activity occured upon incubation with fresh human PMNL stimulated by phorbol myristate acetate (Tl/2 1 uM HC II, 0.35 108 cells/mm : -2 min) or with PMNL extracts prepared by nitrogen cavitation. Antithrombin (dermatan sulfate cofactor) and antichymotrypsin activities of HC II were lost at the same rate. Resting PMNL were ineffective. Inactivation was prevented by several serine-protease inhibitors but was Ca++ /Mg++ independent. Inactivation coincided with the formation of a 54 KD peptide after a first non-inactivating degradation into a 62 KD peptide (native HC II : 76 KD). These reaction products are reminiscent of those described upon incubation with proteinase I from Echis carinatus venom. HC II was inactivated more rapidly than AT III (T 1/2 of AT III in the same conditions -15 min). However, heparin (1-10 ug/ml) strongly accelerated the rate of AT III inactivation and slightly protected HC II, thus reversing the order of inactivation. Dermatan sulfate had no effect on this process.In conclusion, this study shows ; l)both AT III and HC II are rapidly inactivated by PMNL enzymes, thus favoring locally thrombin-mediated processes ; 2) heparin increases AT III degradation by PMNL, a possible route of catabolism operating in patients with low AT III levels during heparin treatment.

In XIth International Congress on Thrombosis and Haemostasis. Schattauer GmbH, 1987. http://dx.doi.org/10.1055/s-0038-1644321.

Full text
Abstract:
The prothrombin activator from the venom of Bothrops neuwidi has been purified to homogeniety by gelfiltration on Sephadex G-100, ion-exchange chromatography on DEAE-Sephacel and metal-chelate affinity chromatography on an Epoxy-activated Sepharose 6B column loaded with ZnCl . The overall purification was about 200-fold, which indicates that the crude venom contains about 0.5 weight % of the prothrombin activator. The venom activator is a single chain protein with an apparent molecular weight of 60,000 dalton. It readily activated bovine prothrombin with a Km of 37.7 uM and a Vmax of 120 umoles prothrombin activated per min/mg of purified venom activator. Venom-catalyzed prothrombin activation was not accelerated by the accessory components of the prothrombinase complex i.e. phospholipids plus calcium-ions and Factor Va. The venom activator does not require added calcium-ions for the expression of its prothrombin-converting activity. Calcium ions do, however, affect the catalytic activity of the venom activator. At 2 mM CaCl there is a 2-fold increase of the rate of venom-catalyzed prothrombin activation. However, at higher CaCl concentrations there is a gradual decrease of the activity of the venom activator. Gelelectro-phoretic analysis of prothrombin activation indicated that the venom activator only cleaved the Arg 323-Ile 324 bond of bovine prothrombin since meizothrombin was the only product of prothrombin activation. The activator did not hydrolyze the chromogenic substrates S2222, S2337, S2238, S2366, S2302 or chromozym TH and its prothrombin converting activity was not inhibited by benza-midine, phenylmethylsulfonylfluoride, dansyl-glu-gly-arg-chloro-methylketone and soybean trypsin inhibitor. However, chelating agents such as EDTA, EGTA and o-phenanthroline strongly inhibited the enzymatic activity of the venom activator. The activity of chelator-treated venom activator could, however, be restored by the addition of an excess CaCl . These results indicate that the enzyme from Bothrops neuwidi does not belong to the serine proteases but has the properties of a metal proteinase. Thus, the activator differs remarkably from Factor Xa, but strongly resembles the prothrombin activator from the venom of Echis carinatus, both structurally and functionally.

Abstract:
Meizothrombin (MT) and meizothrombin des Fragment 1 (MT1) are intermediates in the conversion of prothrombin to α-thrombin (αTH). Due to their transient character, properties of these enzymes are difficult to establish. Isolation of MT1 was achieved by affinity chromatography on D-Phe-Pro-Arginal (FPRal)immobilized on Affi-Gel 10 as originally employed for thrombin purification (Patel et al. Biochim.Biophys. Acta 748,321 (1983)). Human prethrombin 1 was activated with the purified activator from Echis carinatus venom in the presence of Ca++;, benzamidine and FPRal gel at pH 7.8. After exhaustive washing the MT1 was eluted with 0.1 M hydroxylamine in 0.15 M Na acetate buffer, pH 5.5. Under these conditions the MT1 is stable and can bestored at -70°C. Upon changing the pH of the preparation to 8.0, complete conversion into aTH occurred atroom temperature within 48 hours. Homogeneity of both preparations wasdemonstrated by PAGE. The Km and ke, values for MT1 measured on Tos-Gly-Pro-Arg pNA(0.1 M NaCl, 0.01 M TRIS, 0.01 M HEPES, 0.1% PEG, pH 7.8, 25°C) were 15.7 /iM and 126 s-1. The kinetic con stants for the aTH resulting from autocatalytic degradation of MT1 were indistinguishable from those previously established forαTH obtained by Xa activation i.e. 4.77 /μM and 126 s-1. Clotting activity of MT1 was found to be only one fifth as high as that of the resulting μTH(746 u/mg vs. 3900 u/mg as tested using the NIH standard) .Inhibitionof MTl by antithrombin III was alsomuch less rapid than αTH andmost importantly, it was not affected by high affinity heparin( Mr20,300). Under conditions of the experiment (0.3 M NaCl, 0.0rl M TRIS, 0.01 M HEPES, 2.5 mM EDTA, 0.1% PEG, pH 7.8, 25°C; [ATIII] 100 nM, [E] 10 nM), the pseudo first order rate constants in the absence of heparin were 4.04 × 10-3V1 (MTl) and 1.13 × 10-3V1 (αTH), giving apparent second order rate constants of 4.04 × 103 and 1.13 × 10-4M-1s-1. In the presence of 4.5 nM of heparin the observed first order rate constant for MTl remained unchanged whereas it increased to 6.241 × 10-3s-1 (5.5 fold) for αTH. This apparent lack of an effect of heparin may be of significance in vivo.Supported by a Matching Grant from the American National Red Cross and by the Southeastern Michigan Blood Service.
