    Palynology of Carica and Vasconcellea (Caricaceae. The pollen of C. papaya and agreements of Vasconcellea cauliflora, V. cundinamarcensis, V. crassipetala, V. goudotiana, V. x heilbornii var. chrysopetala, V. longiflora and V. sphaerocarpa collected in the Colombian Coffee Growing Zone, using the technique of acetolisis for optic microscopy and the fixation procedure with glutaraldehide, dehydration and ionization with gold-palade, for scanning electronic microscopy was described. The pollen grains were characterized using descriptors, which include the characters of taxonomic value for pollen identification, genetically determined. The most important are the number, position and character of the aperture (NPC and exine ornamentation and stratification. The pollen is of medium size for both genera, tricolporate, zonoaperturate, prolate-spheroid to subprolate, isopolar radial symmetry, tectate, dug, foveolate, with columelas. These characters have demonstrated a great contribution to the taxonomy of Caricaceae because the cluster analysis allowed distinguish very well the two genera.

    Full Text Available Babaco [Vasconcellea x helbornii (Badillo Badillo] is a specie of commercial importance in Ecuador. The present work aimed to establish in vitro shoots of axillary buds from mother plants of babaco kept in greenhouse. Carbendazim and the biostimulant (GERMO-TB01 were applied to the plants. For the disinfection of the explants, three concentrations of Sodium Hypochlorite (1, 1.5 and 2% were evaluated during two times (5 and 10 minutes. In addition, the effect of the use of Gentamicin 50 mg l-1 and Streptomycin 25 mg l-1 in the culture medium was determined. The best results were achieved by using 1.5% Sodium Hypochlorite for 10 minutes and immersion in a solution with both antibiotics for 3 hours. A 68.5% in vitro establishment of the shoots was achieved at 21 days of culture. The results will contribute to in vitro mass propagation of this hybrid.   Key words: antibiotic mixture, babaco, disinfection, micropropagation

The present work was carried out with the objective of establishing a bank of donor plants of the babaco hybrid from cuttings, under semicontrolled conditions. Two-year-old plants grown in greenhouse was used as initial plant material. Subsequently, the stem was divided into different sections of 25 cm in length. These were planted in plastic sheaths with substrate and subjected to a phytosanitary control with 0.5% (v / v Carbendazim fungicide. At six weeks of culture, the number of rooted cuttings, the number and length of shoots and number of leaves per cutting were quantified. The effect of biostimulant application (GERMO-TB01 was also determined to increase the number of axillary shoots. The results of this work allowed to reach a 100% budding and root formation in the different sections of stem. The best results in the formation of new shoots were reached in explants S1, S2 and S3. However, when applying the biostimulant the formation of new shoots increased to 5.82 per stem sections with better quality. Since the results of this work will be available donor plant material to develop in vitro propagation protocols of this hybrid, with high genetic and phytosanitary quality.   Key word: bio-stimulant, donor plant material, greenhouse, rooting

    • Background and Aims Vasconcellea × heilbornii is believed to be of natural hybrid origin between V. cundinamarcensis and V. stipulata, and is often difficult to discriminate from V. stipulata on morphological grounds. The aim of this paper is to examine individuals of these three taxa and of individuals from the closely related species V. parviflora and V. weberbaueri, which all inhabit a hybrid zone in southern Ecuador. • Methods Molecular data from mitochondrial, chloroplast and nuclear DNA from 61 individuals were analysed. • Key Results Molecular analysis confirmed occasional contemporary hybridization between V. stipulata, V. cundinamarcensis and V. × heilbornii and suggested the possible involvement of V. weberbaueri in the origin of V. × heilbornii. In addition, the molecular data indicated unidirectional introgression of the V. cundinamarcensis nuclear genome into that of V. stipulata. Several of the individuals examined with morphology similar to that of V. stipulata had genetic traces of hybridization with V. cundinamarcensis, which only seems to act as pollen donor in interspecific hybridization events. Molecular analyses also strongly suggested that most of the V. × heilbornii individuals are not F1 hybrids but instead are progeny of repeated backcrosses with V. stipulata. • Conclusions The results of the present study point to the need for re-evaluation of natural populations of V. stipulata and V. × heilbornii. In general, this analysis demonstrates the complex patterns of genetic and morphological diversity found in natural plant hybrid zones. PMID:16500954

    2018-04-01

    The aim of the study was to investigate the role of the proteolytic fraction from Vasconcellea cundinamarcensis, designated as P1G10, on the healing of chronic foot ulcers in neuropathic patients with diabetes 2. Fifty patients were enrolled in a prospective, randomized, double-blind trial, to verify the efficacy and safety of a topical dressing formulated with 0.1% P1G10, intended for wound healing, versus a hydrogel (control) protocol. Upon completion of the intervention, the outcome evaluated the number of patients attaining full epithelization (100%), or at least 80% healing. Statistical analysis compared the data on each group for the significance of the differences. Collection of data was finished in week 16, and the results were analyzed by intention to treat. The results showed that, in the control group, 5 patients attained 100% ulcer healing, 3 patients ≥ 80% healing and 11 experienced ulcer changes ≤ 80%, and the remainder showed no changes or their wounds became worse. Meanwhile, in the P1G10 group, 11 patients experienced full healing, 4 had healing ≥ 80% and 5 had ulcer changes ≤ lower than 80%, and the remainder showed no changes or their wounds became worse. The healing incidence for the first endpoint (100% healing) showed that the P1G10 group was 2.95-fold more efficacious than the control group (CI 95%) and 2.52-fold (CI, 95%) higher than its control for the second endpoint (80% healing). These data support the hypothesis that topical application of the proteolytic fraction identified as P1G10 significantly enhances foot ulcer healing compared to hydrogel treatment.

  10. Acute and sub-chronic toxicity studies of three plants used in Cameroonian ethnoveterinary medicine: Aloe vera (L.) Burm. f. (Xanthorrhoeaceae) leaves, Carica papaya L. (Caricaceae) seeds or leaves, and Mimosa pudica L. (Fabaceae) leaves in Kabir chicks.

    Aloe vera (L.) Burm. f. (Xanthorrhoeaceae), Carica papaya L. (Caricaceae) and Mimosa pudica L. (Fabaceae) are widely used in the Cameroonian ethnoveterinary medicine as a panacea, and specifically for gastrointestinal disorders as well as an anthelmintic and antibacterial. The present study evaluated the potential toxicity of the hydroalcoholic extracts of Aloe vera leaves, Carica papaya leaves or seeds, and Mimosa pudica leaves after acute and sub-chronic administration in chicks. For the acute toxicity test a single administration of each of the four hydroalcoholic extracts was given orally at doses ranging from 40 to 5120 mg/kg (n=5/group/sex). In the sub-chronic study, these extracts were given orally as a single administration to chicks at doses of 80, 160, 320 and 640 mg/kg/day for 42 days. The anti-angiogenic properties of these extracts (5-320 µg/mg) were investigated in the chick chorioallantoic membrane in vivo. In the acute toxicity test, none of the four studied hydroalcoholic extracts induced mortality or significant behavioural changes. The sub-acute treatment with the four plant extracts did not alter either the body weight gain or the food and water consumption. However, the results indicated that Aloe vera leaf extract acute treatment by oral route at doses up to 2560 mg/kg did not produce death in 50% (5/10) of chicks during 24h or 14 days of observation, but 20% (2/10) chicks died. The haematological and biochemical analyses did not show significant differences in any of the parameters examined in female or male groups, with the exception of a transient rise in white blood cell counts at high doses (640 mg/kg). Additionally, these extracts did not have the potential for anti-angiogenic effects through the inhibition of neo-angiogenesis in the chick chorioallantoic membrane in vivo. The results showed that the therapeutic use of the hydroalcoholic extracts of Aloe vera leaves, Carica papaya leaves or seeds and Mimosa pudica leaves had very low

    Full Text Available This work was carried out with the aim of documenting the importance of Babaco for the Andean region, its main plant pathogens, and possible control strategies and integrated management, emphasizing the MVB. Was performed a systematic review of scientific papers published in prestigious journals and thesis diplomas, masters and doctorates from various universities. As a criterion for inclusion-exclusion studies were taken into account in the genus Vasconcellea. Ecuador has 15 of the 21 described species, of which more than half are located in the province of Loja. Vascular Wilt Babaco (MVB is caused by a complex of Fusarium fungi that interact with the plant. There are no integrated management strategies for Vascular Wilt Babaco scientifically proven.

  12. Meiotic behavior of wild Caricaceae species potentially suitable for papaya improvement

    2012-01-01

    Full Text Available The purpose of this study was to evaluate the meiotic behavior and determine the meiotic index and pollen viability of representative plants of the wild species V. goudotiana, V. quercifolia and J. spinosa. Meiotic analysis confirmed that the species are diploid and have 18 chromosomes. Meiosis was partially normal, since some abnormalities, e.g, sticky and lagging chromosomes, precocious segregation, lack of synchrony, and disturbances in the spindle fibers were observed. These abnormalities resulted in post-meiotic products (monads, dyads, triads, and polyads that probably contributed to the meiotic index of 85.7 % (V. goudotiana to 95.9 % (J. spinosa; significant variation was observed in the species V. goudotiana. The pollen viability of 68.0% (V. goudotiana to 96.0 % (J. spinosa was reasonably good in these wild species. Crossings in breeding programs involving V. goudotiana should therefore be carefully planned, since part of the gametes of this species is unviable.

    2004-03-01

    The ciliate Ichthyophthirius multifiliis is among the most pathogenic parasites of fish maintained in captivity. In the present study, the effects of the crude methanolic extract of leaves of Mucuna pruriens and the petroleum-ether extract of seeds of Carica papaya against I. multifiliis were investigated under in vivo and in vitro conditions. Goldfish (Carassius auratus auratus) infected with the parasites were immersed for 72 h in baths with M. pruriens extract, and for 96 h in baths with C. papaya extract. There was a 90% reduction in numbers of I. multifiliis on fish after treatment in baths of each plant extract at 200 mg l(-1 )compared to untreated controls. Consequently, parasite-induced fish mortality was reduced significantly. A complete interruption of trophont recruitment was achieved by immersion in the M. pruriens extract. In vitro tests led to a 100% mortality of I. multifiliis in 150 mg/l M. pruriens extract, and in 200 mg/l of C. papaya extract after 6 h. Although the active constituents of the medicinal plant extracts are still unknown, we have demonstrated that they have potential for effective control of I. multifiliis.

  14. Mejoramiento de la germinación, control de la hiperhidricidad y formación de brotes en Vasconcellea stipulata Badillo

    2015-07-01

    Full Text Available Vasconcellea stipulata posee una gran importancia comercial debido a su actividad enzimática y como fuente para el mejoramiento genético de papaya, debido a su resistencia al virus de la mancha anular de esta especie. Sin embargo, debido a su baja regeneración por semillas y al limitado conocimiento de sus propiedades genéticas y farmacéuticas, esta especie no es cultivada ampliamente. La propagación a través del cultivo in vitro de semillas se ha usado para contrarrestar este tipo de problema, pero la hiperhidricidad, un trastorno fisiológico, expresado principalmente en los ejes embrionarios en desarrollo y asociado específicamente a esta especie, es una restricción significativa. Con el fin de obtener material de élite para el cultivo de V. stipulata, el objetivo de este trabajo fue incrementar la germinación, controlar la hiperhidricidad en embriones y evaluar el potencial para inducir respuestas morfogénicas, es decir, la formación de brotes. Nuestros resultados mostraron que es posible aumentar la germinación hasta un 53% en condiciones in vitro, dentro de un período más corto en presencia de peróxido de hidrógeno. Además, la hiperhidricidad se redujo significativamente (50% en condiciones in vitro cuando se incluyó ácido giberélico en bajas concentraciones en el medio 1/2 Nitsch y Nitsch. Esto permitió recuperar hasta aproximadamente el 80% de plántulas viables. Finalmente, otros reguladores de crecimiento vegetal evaluados, indujeron la formación de brotes en yemas axilares y la formación de callos en secciones de hoja derivadas de plántulas.

    Hu, Ye; Liang, Hao; Yuan, Qipeng; Hong, Yuancheng

    2010-08-01

    Glucosinolates were evaluated in 19 traditional Chinese medicinal plants involved in seven different families: Brassicaceae, Capparaceae, Euphorbiaceae, Phytolaccaceae, Tropaeolaceae, Caricaceae and Rubiaceae. The total glucosinolate contents were determined by spectrophotometry. Results showed that the high contents of total glucosinolates were found in some herbs of Brassicaceae, Capparaceae and Euphorbiaceae families, while low total glucosinolate contents were observed in two Rubiaceae herbs. In addition, eight glucosinolates (glucoraphanin, glucoraphenin, sinalbin, sinigrin, progoitrin, 4-hydroglucobrassicin, glucoiberin and glucoibervirin) in these herbs were measured using HPLC, and the data showed that individual glucosinolates and their contents varied at different degrees among the distinct species. The highest contents of cancer-protective compounds were found in the seeds of Raphanus sativus L. (glucoraphenin), Sinapis alba (sinalbin) and Phyllanthus emblica L. (sinigrin).

  20. Ratio-based estimators for a change point in persistence.

    Halunga, Andreea G; Osborn, Denise R

    2012-11-01

    We study estimation of the date of change in persistence, from [Formula: see text] to [Formula: see text] or vice versa. Contrary to statements in the original papers, our analytical results establish that the ratio-based break point estimators of Kim [Kim, J.Y., 2000. Detection of change in persistence of a linear time series. Journal of Econometrics 95, 97-116], Kim et al. [Kim, J.Y., Belaire-Franch, J., Badillo Amador, R., 2002. Corringendum to "Detection of change in persistence of a linear time series". Journal of Econometrics 109, 389-392] and Busetti and Taylor [Busetti, F., Taylor, A.M.R., 2004. Tests of stationarity against a change in persistence. Journal of Econometrics 123, 33-66] are inconsistent when a mean (or other deterministic component) is estimated for the process. In such cases, the estimators converge to random variables with upper bound given by the true break date when persistence changes from [Formula: see text] to [Formula: see text]. A Monte Carlo study confirms the large sample downward bias and also finds substantial biases in moderate sized samples, partly due to properties at the end points of the search interval.

  1. Anaphylaxis Secondary to Prick to Prick Tests to Foods and its Risk Factors

    Lucy Vania Galindo-Pacheco

    2014-01-01

    Full Text Available The diagnosis of food allergy requires a proper anamnesis and diagnostic testing with skin prick tests with fresh foods and/or standardized allergen, or specific IgE tests. The risk of systemic reactions is of 15-23 per 100,000 skin tests performed by prick method, specically anaphylaxis at 0.02%. This paper reports the case of four patients, who while performing prick to prick test with fresh food presented anaphylactic reaction. Implicated foods were fruits of the Rosaceae, Anacardiaceae and Caricaceae families. The severity of anaphylaxis was: two patients with grade 4, one patient grade 2 and one grade 3, all with appropriate response to drug treatment. The risk factors identi ed were: female sex, personal history of atopy, previous systemic reaction to Hymenoptera venom, prior anaphylaxis to prick tests to aeroallergens. We found that a history of positive skin test for Betulla v, can be a risk factor for anaphylaxis in patients with oral syndrome. During testing prick to prick with food anaphylaxis can occur, so it should be made with aerial red team on hand. The history of positivity Betulla v is an additional risk factor in these patients.

    Ninety-four ethanolic extracts of plants used medicinally by the Yanesha, an Amazonian Peruvian ethnic group, for affections related to leishmaniasis and malaria were screened in vitro against Leishmania amazonensis amastigotes and against a Plasmodium falciparum chloroquine resistant strain. The viability of Leishmania amazonensis amastigote stages was assessed by the reduction of tetrazolium salt (MTT) while the impact on Plasmodium falciparum was determined by measuring the incorporation of radio-labelled hypoxanthine. Six plant species displayed good activity against Plasmodium falciparum chloroquine resistant strain (IC(50) Piper aduncum L. and Piper sp.) and the leaves of Jacaranda copaia (Aubl.) D. Don (Bignoniaceae). Eight species displayed interesting leishmanicidal activities (IC50 < 10 microg/ml): Carica papaya L. (Caricaceae), Piper dennisii Trel (Piperaceae), Hedychium coronarium J. König (Zingiberaceae), Cestrum racemosum Ruiz & Pav. (Solanaceae), Renealmia alpinia (Rottb.) Zingiberaceae, Lantana sp. (Verbenaceae), Hyptis lacustris A. St.-Hil. ex Benth. (Lamiaceae) and Calea montana Klat. (Asteraceae). Most of them are used against skin affections by Yanesha people. Results are discussed herein, according to the traditional use of the plants and compared with data obtained from the literature.

    Sytwala, Sonja; Domsalla, André; Melzig, Matthias F

    2015-12-01

    Occurrence of plant latices is widespread, there are more than 40 families of plants characterized to establish lactiferous structures. The appearance of hydrolytic active proteins, incorporated in latices is already characterized, and hydrolytic active proteins are considerable, and for several plant families, the occurrence of hydrolytic active proteins is already specified e.g. Apocynaceae Juss., Caricaceae Dumort, Euphorbiaceae Juss., Moraceae Gaudich and Papaveraceae Juss. In our investigation, focused on latex bearing plants of order Asterales, Asteraceae and Campanulaceae in particular. The present outcomes represent a comprehensive study, relating to the occurrence of proteolytic active enzymes of order Asterales for the first time. 131 different species of Asteraceae and Campanulaceae were tested, and the appearance of plant latex proteases were determined in different quantities. Proteolytic activity was investigated by inhibitory studies and determination of residual activity in the following, enable us to characterize the proteases. Most of the considered species exhibit a serine protease activity and a multiplicity of species exhibited two or more subclasses of proteases. Copyright © 2015 Elsevier Masson SAS.

    Carica papaya is a member of the Caricaceae. Its leaves have been used in folk medicine for centuries. Recent studies have shown its beneficial effects as an anti-inflammatory agent (Owoyele et al 2008) and anti-tumour15 as well as antioxidant and wound healing properties7. The study has shown that the effect of carica papaya leaves juice intake also can accelerate the rate of increase in platelet count among the patients infected with dengue fever and dengue haemorrhagic fever18. With all the goodness of carica papaya leaves, a formulation with addition of virgin coconut oil (VCO) is produced to give an enhanced supplement beverage to market nowadays. Virgin coconut oil is well known as anti-oxidant4. The combination of these two substances gives a balance combination in healthy supplement. In recent years the application of emulsion is rapidly increasing in many fields such as cosmetics and paints. Emulsions are dispersions of droplets of one liquid in another, immiscible, liquid in which the droplets are of colloidal or near-colloidal sizes. The combination of water and oil (VCO) with addition of non-ionic surfactant Tween80 was constructed using ternary phase diagram. By considering the Hydrophilic-Lipophilic Balance (HLB) value of each substance will help in producing a stable emulsion.

    Carica candamarcensis is a species from the Caricaceae family whose immature fruit contains latex with large amounts of cysteine proteinases. In prior studies, we isolated two of these enzymes displaying mitogenic activity when incubated with L929 fibroblastic cells. One of the fractions containing these enzymes (P1G10) was shown to enhance wound healing of skin and to accelerate healing of chemically induced gastric ulcer. In this study we evaluate the effect of P1G10 on heat-induced, third-degree burn using a rodent model. The results show that 0.1% P1G10 accelerates epithelisation while the effect of 1% or 0.01% P1G10 is not significantly different to 1% silver sulphadiazine, 2% papain or the hydrosoluble vehicle used as control. In a double-blind randomised experiment comparing the healing response of 0.1%, 1% and the vehicle alone, we confirmed the enhanced healing property of P1G10. Histological analysis of burn-tissue sections following treatment with P1G10 support these observations. These results extend the healing properties of these groups of enzymes to a different type of trauma and open the way to future clinical applications. Copyright (c) 2009 Elsevier Ltd and ISBI.

    Rodríguez-Rosell, D, Mora-Custodio, R, Franco-Márquez, F, Yáñez-García, JM, González-Badillo, JJ. Traditional vs. sport-specific vertical jump tests: reliability, validity, and relationship with the legs strength and sprint performance in adult and teen soccer and basketball players. J Strength Cond Res 31(1): 196-206, 2017-The vertical jump is considered an essential motor skill in many team sports. Many protocols have been used to assess vertical jump ability. However, controversy regarding test selection still exists based on the reliability and specificity of the tests. The main aim of this study was to analyze the reliability and validity of 2 standardized (countermovement jump [CMJ] and Abalakov jump [AJ]) and 2 sport-specific (run-up with 2 [2-LEGS] or 1 leg [1-LEG] take-off jump) vertical jump tests, and their usefulness as predictors of sprint and strength performance for soccer (n = 127) and basketball (n = 59) players in 3 different categories (Under-15, Under-18, and Adults). Three attempts for each of the 4 jump tests were recorded. Twenty-meter sprint time and estimated 1 repetition maximum in full squat were also evaluated. All jump tests showed high intraclass correlation coefficients (0.969-0.995) and low coefficients of variation (1.54-4.82%), although 1-LEG was the jump test with the lowest absolute and relative reliability. All selected jump tests were significantly correlated (r = 0.580-0.983). Factor analysis resulted in the extraction of one principal component, which explained 82.90-95.79% of the variance of all jump tests. The 1-LEG test showed the lowest associations with sprint and strength performance. The results of this study suggest that CMJ and AJ are the most reliable tests for the estimation of explosive force in soccer and basketball players in different age categories.

Determinant factors of physical performance and specific throwing in handball players of different ages. J Strength Cond Res 32(6): 1778-1786, 2018-This study aimed to analyze various fitness qualities in handball players of different ages and to determine the relationships between these parameters and throwing velocity. A total of 44 handball players participated, pooled by age groups: professional (ELITE, n = 13); under-18 (U18, n = 16); under-16 (U16, n = 15). The following tests were completed: 20-m running sprints; countermovement jumps (CMJs); jump squat to determine the load that elicited ∼20 cm jump height (JSLOAD-20 cm); a progressive loading test in full squat and bench press to determine the load that elicited ∼1 m·s (SQ-V1-LOAD and BP-V1-LOAD); and handball throwing (jump throw and 3-step throw). ELITE showed greater performance in almost all sprint distances, CMJ, JSLOAD-20 cm, and bench press strength than U18 and U16. The differences between U18 and U16 were unclear for these variables. ELITE also showed greater (p handball throwing velocity is strongly associated with lower-limb strength, although upper-limb strength, jumping and sprint capacities also play a relevant role in throwing performance, suggesting the need for coaches to include proper strength programs to improve handball players' throwing velocity.

    Rodríguez-Rosell, D, Franco-Márquez, F, Mora-Custodio, R, and González-Badillo, JJ. Effect of high-speed strength training on physical performance in young soccer players of different ages. J Strength Cond Res 31(9): 2498-2508, 2017-The aim of the present study was to compare the effectiveness of low-load, low-volume weight training combined with plyometrics on strength, sprint, and jump performance in soccer players of different ages. Eighty-six soccer players from the same academy were categorized into 3 groups by age (under 13 years, U13, n = 30; under 15, U15, n = 28; and under 17, U17, n = 28) and then randomly assigned into 2 subgroups: a strength training group (STG) and a control group (CG). The strength training program was performed twice a week for 6 weeks and consisted of full squats (load: 45-60% 1 repetition maximum; volume: 3 set of 8-4 repetitions), jumps, and straight line sprint exercises. After training intervention, the STGs showed significant improvements in maximal strength (7.5-54.5%; p soccer players in most variables, whereas U15 showed higher improvements in jump and strength parameters than U17 (ES: 0.25-0.90) soccer players. Thus, although our results indicates that a combined weight training and plyometrics program may be effective in eliciting gains in strength, jump, and sprint in soccer players of different ages, the training program used appears to be generally less effective as the age of the soccer players increased. Therefore, it appears that training characteristics (mainly volume, intensity, and type of exercise) should be modified in relation to maturity status and initial strength level.

    Full Text Available Introducción: El liposarcoma pleomórfico es el subtipo con mayor malignidad, presenta recurrencia local de 37% y metástasis en 10 años de 41%, porcentaje que aumenta directamente con el tamaño de la lesión; además, presenta una supervivencia a los 10 años de 39%. Objetivo: Presentar un caso de esta enfermedad en un hombre sin antecedentes de importancia quien presentó metástasis a pulmón posterior al diagnóstico y tratamiento de un liposarcoma pleomórfico. Discusión: En el grupo de los liposarcomas se encuentran 4 tipos diferentes: El liposarcoma bien diferenciado, desdiferenciado, pleomórfico y mixoide. A pesar de tener poca vascularización el porcentaje de metástasis, su pronóstico y dificultad para extirpación quirúrgica varía según el tipo histológico. En cuanto el diagnóstico: la radiografía simple, la ecografía, la Tomografía computarizada (TC y la resonancia magnética (RM son herramientas diagnósticas válidas para el estudio del liposarcoma. El tratamiento es controvertido debido a la tasa de recurrencia después de la resección quirúrgica, la cual oscila entre 0-69%. Conclusión: En pacientes con cuadros clínicos característicos de lesiones tumorales es importante hacer un diagnóstico oportuno por medio de herramientas imagenológicas y quirúrgicas como el caso de biopsias intraoperatoria para así clasificarlo según el subtipo de liposarcoma, evaluar el tratamiento de elección y evaluar pronóstico y sobrevida del paciente.paciente.
