En este documento se analiza la problemática del desarrollo basado en industrias de commodities. Al respecto se postula que los enfoques tradicionales no son suficientes para entender las especificidades de estos procesos y sugiere que un marco conceptual adecuado debería tomar en cuenta la evolución simultánea de tres esferas distintas de la sociedad: la organización industrial del sector productivo; la estructura y comportamiento del aparato regulatorio y la organización social de las comunidades en las que se lleva a cabo la explotación de los recursos.

A presente invenção trata de um produto denominado cola de fibrina, de grande eficácia, utilizada em várias indica$ões na área médica, bem como de um processo para sua preparação. A cola de fibrina derivada de veneno de cobra, segundo a presente invenção compreende uma SOLUÇÃO I e uma SOLUÇÃO II, consistindo a SOLUÇÃO I de uma fração de veneno de cobra liofilizado, diluída em água bidestilada até atingir concentração entre 80-90 microgramas/ml, sendo para cada parte desta diluição adicionados vinte partes de uma solução de um sal de cálcio a 400 microgramas/ml e, consistindo a SOLUÇÃO II em um crioprecipitado obtido a partir de plasma fresco congelado a -20°C, o qual deve conter, em média, 150-250mg de fibrogênio, 80-120 unidades do fator VIII, 20-30% do fator XIII, 40-70 unidades do fator "von Willibrand" e de 50-60mg de fibronectina.

The bone repair process is controlled by complex molecular mechanisms that involve systemic and local factors. Fibrin glue is derived from human plasma and mimics the final pathway of coagulation network. Tranexamic acid inhibits fibrinolysis and prevents or decreases the formation of degradation products of fibrin and fibrinogen. The purpose of this study was to evaluate histologically in rats the effect of tranexamic acid associated with the fibrin glue on bone healing. The experiment used 60 (n = 5) male rats in: GI: Control, GII: fibrin glue, GIII tranexamic acid and GIV /fibrin glue/tranexamic acid. Bone defect (2.5mm diameter) was created in right tibia. The animals were euthanized at 7,14 and 30 days postoperatively, and the pieces were processed with hematoxylin and eosin. The results showed at 7 days post-operative surgical cavity filled with dense connective tissue rich in fibroblasts, permeated by delicate neoformed bone trabeculae in percentage of 70-80% for GI, GII and GIII and GIV to 94.8%. At 14 days post-operative newly formed bone was found between 75-85% for GI, GII and GIII and percentage above 95% for GIV. At 30 days postoperative GI and GIV showed 95-100% of mature bone tissue; GII and GIII in percentage close to 80-90%. Based on the results and methodology is concluded that fibrin / tranexamic acid glue association has positive action on bone repair.

Cryopreservation of sperm is important to preserve the germplasm from animals of genetic value, which can die unexpectedly. This study compares conventional and automated methods of cryopreservation of spermatozoa obtained from the epididymis of bulls post-mortem. Twenty-two epididymides were obtained from a commercial slaughterhouse. Spermatozoa were collected from the tail of the epididymis using the retrograde flow technique. Thus, the samples, which were diluted in 10 ml of extender without glycerol (Botubov® I, Botupharma, Botucatu, SP, Brazil), were evaluated on motility, sperm vigor, structural and functional (swelling hypoosmotic test) membrane integrity, mitochondrial activity, sperm viability and ADN fragmentation. The samples were divided into two aliquots and diluted in extender with glycerol (Botubov® II, Botupharma, Botucatu, SP, Brazil) at a concentration of 50x106 motile sperm/0.5 French straws. One sample was frozen by the conventional method (4 hours at 5°C, in a refrigerator and 20 min in nitrogen vapor) and the other by the automated method (Cryogen® Dualflex, Neovet, Uberaba, MG, Brazil). The parameters were higher in all the tests of fresh sperm samples, with the exception of the swelling hypoosmotic test, which showed no significant difference when the results were compared with sperm frozen by the conventional method. The average motility of fresh spermatozoa was 74%, and conventional and automated averages were 29 and 25%, respectively. Therefore, although cryopreservation techniques reduce sperm quality parameters, the viability of the sperm is maintained, and these methods can be used to preserve sperm.

Desde hace mucho tiempo, los administradores de vida silvestre han buscado conocer acerca de la ecología de las enfermedades y parásitos que afectan al venado cola blanca (Odocoileus virginianus ) (por ejemplo vea Whitlock 1939). Este es un importante campo de estudio porque las enfermedades y parásitos pueden afectar nocivamente las poblaciones de venados, otros animales silvestres, el ganado y humanos (Davidson et al. 1981). El venado cola blanca ha recibido mucha atención en la literatura acerca de sus enfermedades y parásitos y tratados completos se han dedicado al tema (por ejemplo, vea Davidson et al. 1981). Los avances recientes en nuestra comprensión de la ecología de las enfermedades y parásitos del venado cola blanca han sido realizados por científicos de las universidades y organismos estatales y federales. Una gran cantidad de enfermedades y parásitos causan morbilidad y mortalidad en el venado cola blanca. También se han observado alteraciones en la conducta del venado, el éxito reproductivo y sobrevivencia (Matschke et al. 1984).
