Resumen

This paper reports rapid and eco-friendly biosynthesis of silver nanoparticles using latex of two different plants Jatropha curcas (Jc) and Lannea grandis (Lg). Latex of these plants act as both reducing as well as capping agent. The surface plasmon resonance (SPR) band of as-synthesized silver nanocolloids (AgNC) appeared at 440 nm and 415 nm for the AgNC synthesized by latex of Jc and Lg, respectively. TEM images show that the latex of Lg produced smaller regular-shaped particles than those produced by latex of Jc. The influence of different synthesis parameters like concentration of latex, concentration of metal ion, time of reaction etc., on the morphology of the particles were also studied by monitoring UV-Vis spectra of the samples.

Resumen

This study focused on the physical properties of latex extracted from five species of Artocarpus J.R.Forster & G.Forster, namely: A. altilis (Parkinson) Fosberg, A. blancoi Merr, A. camansi Blanco, A. heterophyllus Lam., and A. ovatus Blanco as potential natural adhesives. Surface morphology showed that all five Artocarpus spp. have no specific forms, but otherwise flexible and viscoelastic. Contact angle measurements showed that all samples of Artocarpus spp. were hydrophilic with low contact angle values owing to the contents of natural source of the latex. FTIR analysis matched all Artocarpus latex samples to that of Polyvinyl acetate. Highest resin content was found on A. ovatus with all the species containing natural resin. It was also confirmed that out of the three stress strain analyses, A. camansi had the highest values for tensile strength, A. ovatus had the highest values for Young’s modulus of elasticity and the highest percentage elongation values belonged to A. heterophyllus. Adhesive shear strengths with maximum force values were highest in A. ovatus. Through cluster analysis, out of the eight variables tested A. heterophyllus was the outgroup being attributed to its latex gum-like property. All the above tests and analyses suggested that latex of all five Artocarpus spp. were similar in characteristics to polymer adhesive. Among which A. camansi and A. ovatus exhibited high results on adhesive strength tests.

Resumen

Natural Rubber (NR) latex obtained from Hevea brasiliensis contains a wide particle size distribution. The aim of this study is to investigate the effect of small rubber particles (SRP) and large rubber particles (LRP) on the characteristics of film formation. The rubber particle with different mean diameters can be separated by centrifugation at various speeds to prepare SRP and LRP latex. The average size of SRP and LRP were characterized by light scattering technique to show that the size of SRP was in the range of 0.20 μm, while that of LRP was larger with the wide distribution. SRP and LRP latex were dried at room temperature to study the film formation behaviors. The results showed that the film compaction time increased with increasing the particle size of NR. Furthermore, the rubber film were aged at room temperature for 3 weeks in order to observe the surface morphology using atomic forced microscopy (AFM) by tapping mode. The AFM images showed that SRP readily formed a coalescence film, while LRP showed individual particles on the surface of film at 24 h of storage time. The surface of both SRP and LRP films was smoother after storage. However, LRP film still showed individual particles on the surface after 3 weeks of storage time.

Resumen

Calotropis procera is a wild-growing plant that belongs to the family Asclepiadaceae, commonly found in the tropical regions and is used in the treatment of diseases such as ulcer, inflammation, wound healing, etc. This confers to the increased use of medicinal plants as the major source of traditional medicine worldwide. This study is aimed at evaluating the toxicological effects of Calotropis procera latex on biochemical and hematological parameters in albino rats with a view to understanding the safety of the latex following systemic use. Fifteen (15) albino rats were divided into five groups of three rats each. Group one served as the control, group two received 0.05 ml of the latex solution per kg body weight of the rats , group three received 0.2 ml of the latex solution per kg body weight of the rats , group four received 0.4 ml of the latex solution per kg body weight of the rats , while group five received 0.6 ml of the latex solution per kg body weight of the rats for 14 days. Biochemical evaluations revealed a significant increase in the serum levels of aspartate aminotransferase (83.33 ± 1.76c) and total bilirubin (6.27 ± 4.44b) and a progressive decrease in albumin (3.93 ± 0.04a) with increased concentration of the latex. There was no significant change in the levels of alanine aminotransferase and alkaline phosphatase in all the treated groups. Hematological analyses revealed a significant (p<0.05) decrease in packed cell volume (31.33 ± 1.76a), hemoglobin (10.43 ± 0.59a), red blood cell count (3.90 ± 0.06a) and total white blood cell count (4.10 ± 0.15a) in all the treated groups compared to the control. In conclusion, the results of this study suggest that Calotropis procera latex is relatively toxic as observed in the blood and biochemical parameters related to liver function. Hence, it is recommended that caution should be taken in its use for the treatments of diseases such as wound healing as exposure to the circulatory system can cause vulnerability to its toxic effects.

Resumen

Several tests for the biological evaluation of bioceramic materials and medical devices are provided in specific international standards, where in vitro tests have a major role. Tests involving exposure of cells in culture require the use of validated positive controls, which, in the same preparation and treatment conditions, present a substantial and well-known cytotoxicity. The present work aimed to test and validate 3 different sources of low cost, commercially available latex, as positive controls in cytotoxicity tests for bioceramic materials performed by indirect exposure. The tested origins for latex samples were: surgical gloves without powder, 100% pure amber latex hospital-grade tourniquets and 60 % latex White tubing. MC3T3-E1 murine pre-osteoblasts in culture were exposed to conditioned media (extracts) of each material tested, along with sintered stoichiometric hydroxyapatite bioceramics, and polystyrene beads as negative control. Cell viability was determined by XTT and Crystal Violet Exclusion tests. Concentration curves of the extracts were performed to obtain the DC50. Only the 100% pure amber latex tubing was proven to be cytotoxic, with cell survival less than 5%. This material did not affected neighboring groups at the same experimental system. Moreover, latex samples showed great repeatability in different tests against latex and biomaterials, with consistent toxicity under 20% cell survival as shown in 3 different cell viability parameters. We conclude that fragments of latex ambar tubing are suited as effective positive controls in tests of medical bioceramic materials.

Resumen

Hevea brasiliensis natural rubber (NR) latex is a very important commercial source of elastomers. It is not only a source for dry NR rubber but also the feedstock for the latex glove dipping industry. The particles of freshly tapped latex are known to be stabilized by proteins and lipids that come with the latex from the tree. These non-rubbers [, especially proteins and lipids, confer to the rubber and latex excellent properties unsurpassed by any synthetic latex [. Recent structural studies of NR revealed that the NR molecules comprise of 2 trans-isoprene units connected to a long-chain cis-isoprene units. Two terminal groups, referred to as ω and α, have been postulated to link with mono-and di-phosphate groups associated with phospholipids by H-bonding at the α-terminal, whereas the ω-terminal is a dimethylallyl group links to protein by H-bonding [. Although numerous studies have been published on the surface structure of the natural rubber particle [4-, none of these offered a direct in situ visualization of the intact particle surface. This is because of any attempt to remove this surface layer of proteins and lipids results in an immediate destabilization of the latex. The second part focused on the using of Atomic Force Microscopy (AFM) and Confocal Fluorescence microscopy to visualize and delineate the structure of the proteins and lipids layer on the latex particle surface in situ.

Resumen

Aloe ghibensis Sebsebe & Friis is traditionally used in Ethiopia for the treatment of various ailments including skin problem, wounds and malaria. Phytochemical constituents and antileshimanial properties of the leaf latex of A. ghibensis have not been reported. The objective of this study was, therefore, to determine the phytochemical constituents and in vitro antileishmanial activities of the leaf latex of A. ghibensis and its major compounds against two Leishmania species. Preparative TLC was used to isolate compounds from the leaf latex of A. ghibensis and spectroscopic techniques including 1D- and 2D-NMR as well as ESI-MS were employed to elucidate structures of the isolated compounds. In vitro antileishmanial activity was performed against promastigotes and axenically cultured amastigotes of Leishmania aethiopica and Leishmania donovani clinical isolates using Alamar Blue assay. Phytochemical investigation led to the isolation of two major anthrones, identified as aloin A/B and 7-hydroxyaloin A/B. Both the leaf latex of A. ghibensis and isolated compounds showed antileishmanial activity with IC50 values ranging from 1.6 ± 0.43 to 3.64 ± 0.09 µg/ml and 1.87 ± 0.21 to 3.72 ± 0.12 against promastigotes and axenically cultured amastigotes of L. aethopica and L. donovani, respectively. Moreover, the test substances were found to be less toxic (LC50 = 145 ± 0.72 to 156 ± 0.08 µg/ml) than amphotericin B (LC50 = 12.11 ± 0.51 µg/ml) towards human monocytic cell line (THP-1). The present study revealed that the latex and pure compounds possess genuine antileishmanial activity with high selectivity indices (SIs). Therefore, the isolated compounds can be used as a scaffold for the development of effective drugs for leishmaniasis.

Resumen

Nanotechnology has the potential to produce a variety of new materials in the coming years, as a result of the design of novel nanoparticles with new physicochemical characteristics. However, their potential to adversely affect the environment and human health must be addressed. The toxicity of polystyrene latex (PSL) nanoparticles with various functional groups toward Escherichia coli KP7600 strain was investigated using the colony count method, and confocal microscopy observations. It was found that the positively charged PSL nanoparticles led to the death of the bacterial cells. Confocal observations of the bacterial cells after 1 h of exposure to the amine-modified, positively-charged PSL nanoparticles in an aqueous NaCl solution showed that the surfaces of the dead cells were almost entirely covered with the nanoparticles. No uptake of the nanoparticles into the bacterial cells was observed, regardless of the cell viability. It is likely that the adhesion of the positively charged nanoparticles onto the surface of the bacterial cells (due to the electrostatic attractive force) caused a decrease in the fluidity of the cell membrane, and the inhibition of metabolism through the cell membrane led to the death of the bacterial cells.

Resumen

In this study, influences of mixing procedure on the latex adsorption behavior, slurry fluidity and setting time of latex modified cement paste (LMCP) mixed with polycarboxylate (PC) as superplasticizer were analyzed. There were three kinds of mixing procedure: LMCP added latex later than PC (LMCP-L), LMCP added latex before PC (LMCP-B), LMCP added latex and PC simultaneously (LMCP-S). The results show that, the adsorption isotherm of SAE latex by cement grains fits the Langmiur type, and the presence of PC can affect the adsorption behavior. Regardless of the mlatex/mcement (4% or10%), LMCP-B had the highest amount of adsorbed latex and slurry fluidity while LMCP-L had the lowest. And, the LMCP-B also had the longest initial and final setting times, while the setting times of LMCP-L and LMCP-S were comparable.

Resumen

AbstractAncient Mesoamericans were making rubber by at least 1600 B.C, mixing latex from Castilla elastica trees with juice from Ipomoea alba (morning glory) vines. The combination of ethnographic, archaeological and mechanical data presented in this text illustrate that ancient Mesoamericans had fully developed this process, and consciously tailored the mechanical properties of rubber to suit requirements of specific applications by altering the ratio of latex to I. alba juice. Our data focus on rubber balls, sandal soles, and rubber bands for hafting and joining. Elasticity, the mechanical property that defines the ability of a rubber ball to bounce, is maximized with a 1:1 volume ratio of latex to I. alba juice. Rubber with high wear resistance, vital to the life and functionality of a sandal sole, can be created by mixing C. elastica latex with 25 percent I. alba juice by volume. Unprocessed C. elastica latex, without I. alba juice, is the material best suited for joining applications, such as adhesives or hafting bands, where strength and ability to absorb shock is of the greatest importance. Tribute data from sixteenth-century codices substantiate that rubber was processed for specific applications within the Aztec empire—rubber and latex goods were processed and constructed in the C. elastica-bearing regions, and then shipped to the capital for use or further distribution.

Resumen

Abstract Physical and biological properties were determined for a preliminary production run of low-ammonia latex from guayule (GR latex). GR latex, and dipped films produced from compounded GR latex, contain none of the Hevea allergens known to elicit Type I systemic allergic reactions. The polymer phase of GR latex has a lower bulk viscosity and a higher resin content than that of NR. In addition, GR latex serum and rubber lack the activating components present in NR latex. As a result, GR latex cures more slowly and reaches a lower state of cure. The aged stress-strain properties of cured GR films are nonetheless similar to those of NR films.

Resumen

Abstract Natural rubber is an irreplaceable raw material vital to industry, transportation, medicine and defense, largely produced from clonal plantations of Hevea brasiliensis in Southeast Asia. Additional rubber-producing crops are greatly desired to increase biodiversity, protect supplies, and provide a safe alternative for people suffering from Type I latex protein allergy. Basic and applied research approaches were used to make the production of latex (Yulex® latex) from Parthenium argentatum (guayule) a commercial reality. In contrast to Hevea brasiliensis, from which rubber latex is tapped by hand from laticifers, guayule latex rubber is contained within individual bark parenchyma cells. Processing involves disrupting these cells to release the rubber particles, and then purifying the latex. As in the Hevea industry, latex concentration can be achieved by centrifugation and/or by creaming agents. An artificially produced guayule natural rubber latex is then produced, under the material name of “Yulex® latex”. The Yulex Pilot Plant has been constructed, optimized and automated, and extracts then purifies latex from guayule shrub without detectable losses. The natural rubber polymers in guayule latex are high molecular weight and products made from this material have the desired high performance properties. Because guayule latex contains very little protein, all of which is hydrophobic and bound to the rubber phase, and because none of the protein cross-reacts with Type I latex allergy to Hevea latex products, its use is initially aimed towards the high-value medical products marketplace. Clinical and performance trials continue to ensure that guayule processing provides a safe, high performance, non-allergenic natural rubber latex that is safe for human use.

Resumen

Abstract Exogenous Ags that are processed in vacuolar endocytic compartments are generally presented by class II MHC molecules and not class I MHC (MHC-I) molecules, which conventionally present cytoplasmic or endogenous Ags. Accordingly, i.v. immunization of C57BL/6 mice with soluble OVA did not elicit a CD8 T cell response. However, i.v. immunization with OVA coupled to Latex particles (Latex-OVA) elicited an OVA-specific CD8 T cell response in vivo (particles from 59 to 2000 nm diameter were effective). In vitro, Latex-OVA was processed by H-2b macrophages and presented by Kb at least 100- to 1000-fold more efficiently than was soluble OVA. Inhibition of phagocytosis by cytochalasin D blocked the processing of Latex-OVA, whereas processing was not blocked by Brefeldin A. Latex-OVA was presented directly by H-2b macrophages or after "regurgitation" of processed OVA peptide from viable MHC-disparate macrophages for binding to surface Kb molecules on fixed H-2b macrophages. Peptide regurgitation was observed during processing of both Latex-OVA and Salmonella typhimurium 14028s that express an OVA fusion protein (Crl-OVA). However, the regurgitation pathway was less efficient than direct processing by viable H-2b macrophages. Thus, macrophages express an alternate pathway that allows MHC-I presentation of vacuolar exogenous particulate Ags, including inert synthetic particles without lipid membranes and intravacuolar bacteria. Peptides from these Ags are released from intracellular compartments to bind to surface MHC-I molecules, but peptide-MHC-I complexes also may be generated within intracellular compartments.

Resumen

Abstract During the processing of particulate Ags, it is unclear whether peptide:class II MHC (MHC-II) complexes are formed within phagosomes or within endocytic compartments that receive Ag fragments from phagosomes. Murine macrophages were pulsed with latex beads conjugated with OVA. Flow or Western blot analysis of isolated phagosomes showed extensive acquisition of MHC-II, H-2M, and invariant chain within 30 min, with concurrent degradation of OVA. T hybridoma responses to isolated subcellular fractions demonstrated OVA(323–339):I-Ad complexes in phagosomes and plasma membrane but not within dense late endocytic compartments. Furthermore, when two physically separable sets of phagosomes were present within the same cells, OVA(323–339):I-Ad complexes were demonstrated in latex-OVA phagosomes but not in phagosomes containing latex beads conjugated with another protein. This implies that these complexes were formed specifically within phagosomes and were not formed elsewhere and subsequently transported to phagosomes. In addition, peptide:MHC-II complexes were shown to traffic from phagosomes to the cell surface. In conclusion, phagosomes are fully competent to process Ags and generate peptide:MHC-II complexes that are transported to the cell surface and presented to T cells.

Resumen

Studies were carried out to natural papain inhibitor from papaya latex. Fresh latex from green fruits of Carica papaya was collected and immediately transported in ice bath to the lab, from which three fractions with inhibitor effect of esterase papain activity were isolated by latex dialysis, Sephadex G-25 gel filtration and ionic exchange chromatography in SP-Sephadex C-25. The isolated fractions, identified as inhibitors I and II, showed a negative reaction with ninhydrin; however, the fraction identified as P-III showed positive reaction with ninhydrin. Kinetics data showed non-competitive inhibition (inhibitor I) and uncompetitive (inhibitors II and P-III).

Resumen

Abstract Background: Assays to screen for and confirm the presence of the antibody for human T-lymphotropic virus type I (HTLV-I) are currently performed with serum or plasma. We developed and evaluated a new counting immunoassay (CIA) for the detection of HTLV-I antibody in whole blood, using recombinant and synthetic peptide antigens. Methods: We assessed the CIA for detection of HTLV-I antibody in whole blood and plasma. The CIA is an immunity-measuring method that combines latex agglutination with particle-counting technology. The numbers of agglutinated latex particles, single latex particles, and blood cells in a sample are measured based on differences in particle size between latex particles and blood cells. Results: The CIA and ELISA methods were in agreement for all 24 plasma samples tested, including those from 6 patients with HTLV-I-associated diseases, 6 HTLV-I carriers, and 12 HTLV-I antibody-negative individuals. The concordance between the ELISA (plasma) and the CIA (whole blood) for samples from 24 patients was 100%. The concordance between a particle agglutination method (plasma) and the CIA (plasma or whole blood) for 1065 patients was 99.5%. The concordance between results obtained for 1065 pairs of plasma and whole blood samples with the CIA method was 100%. HTLV-I antibody in whole blood was stable for 3 days after blood collection. With this CIA method, results were available within 15 min. Conclusions: The CIA method can be used in screening for HTLV-I. The use of whole blood rather than serum or plasma reduces the sample volume and number of blood collections required, as well as assay time.

Resumen

Degradation for biodegradable natural rubber (NRL) films by Bacillus megaterium sp. is investigated. A common soil bacterium, Bacillus megaterium sp. is one of the largest eubacteria. This bacterium has large potential in degradation process for biodegradable natural rubber latex film. Specified method is used to cultivate the bacteria using suitable media. The growth of bacteria is studied through optical density and dry weight as a function of time. The optical density at specific wavelength with different stages of bacterial growth is used to determine their mid-log growth phase of the cell. The optimum time achieved to insert NRL films is between 17 to 20 hours of incubation period. Growth curve of Bacillus megaterium sp. gives an equation of Y=2.3401X. The biodegradation behaviour of Bacillus megaterium sp. is further investigated to access the viability as accelerating media for biodegradation of NRL films.
