Intraspecific variability of Bipolaris sorokiniana isolates determined by random-amplified polymorphic DNA (RAPD)
Authors: Aida T.S. Matsumura, Ariano M. Prestes, Sueli T. Van Der Sand, Andr?©ia M.R. de Oliveir
Isolates of Bipolaris sorokiniana were analyzed by random-amplified polymorphic DNA (RAPD) techniques to determine the amount of intraspecific genetic variability and to study host-pathogen interactions. Ten isolates originated from different regions of Brazil were examined. Plants of the wheat cultivars BR8, BH1146 (original .. Read More»

Growth hormone mRNA expression in the pituitary of Bos indicus and Bos taurus x Bos indicus crossbred young bulls treated with recombinant bovine somatotropin
Authors: S.M.Z. Di Mauro, L.R. Furlan, M.I.T. Ferro, M. Macari andJ.A. Ferro
The effects of breed and of recombinant bovine somatotropin (rbST) treatment on growth hormone gene expression were studied in young bulls. The experiment was completely randomized in a [2 x 2]-factorial arrangement, using two levels of rbST (0 or 250 mg/animal/14 days), and two breed groups (Nelore and Simmental x Nelore cros..

Ectodermal dysplasias (group A): elaborationof a computerized database to help withgenetic-clinical diagnosis(Displasias ectod?©rmicas do grupo A:elabora?§?£o de um banco de dadosinformatizado para aux?lio ao diagn?³sticogen?©tico-cl?nico)
Authors: Toni Lisboa Costa
Ectodermal dysplasias are conditions that involve structures derived from the ectoderm, such as the epidermis and its enclosures, constituting a large and complex nosologic group, composed of rare entities with genetic etiology (in their majority). Freire-Maia, in 1971 and 1977, proposed a clinical definition and a clinical-mn.. Read More»

Inheritance of resistance to Meloidogyne incognita race 2 in the hot pepper cultivar Carolina Cayenne(Capsicum annuum L.)
Authors: Fausto de Souza-Sobrinho, Wilson Roberto Maluf, Luiz A.A. Gomes and Vicente Paulo Campos
Root-knot nematodes of the genus Meloidogyne are important pathogens affecting vegetable crop production in Brazil and worldwide. The pepper species Capsicum annuum includes both hot and sweet peppers; very little emphasis has been placed on breeding sweet peppers for nematode resistance. We report on the inheritance of resist.. Read More»

Greater genetic variability in Argentine Creole than in Thoroughbred horses based on serum protein polymorphisms
Authors: S. D?az, F.N. Dulout and P. Peral-Garc?a
Genetic polymorphism was analyzed for five blood proteins: albumin - Al, esterase - Es, α1B-glycoprotein - Xk, transferrin - Tf and hemoglobin - Hb in 200 Thoroughbred (TB) and 124 Argentine Creole (AC) horses. Of the five systems examined, Tf and Hb were not in Hardy-Weinberg equilibrium in either breed and Es was not i.. Read More»

CENP-B is a conserved gene among vegetal
Authors: Olga Barbosa-Cisneros and Rafael Herrera-Esparza
To explore the CENP-B centromere protein in beans, carrots, onions and potatoes, total RNA was isolated and reverse transcribed by PCR, and the cDNA encoding the CENP-B amino terminus domain amplified using CENP-B oligonucleotides. Blots containing PCR products were hybridized with a nick-translated pG/CNPB probe containing a .. Read More»

A model system for testing gene vectors using murine tumor cells on the chorioallantoic membrane of the chick embryo
Authors: Sergio U. Dani and Rachel Espindola
We developed a model system for testing gene vectors, based on the growth of murine tumors on the chorioallantoic membrane (CAM) of embryonic chickens. The ability of selected murine cells to grow on the CAM was rated according to the following criteria: i) formation of tumor masses; ii) metastasis formation; iii) reproducibil.. Read More»

A technique to obtain fibroblast cells from skin biopsies of living bats (Chiroptera) for cytogenetic studies
Authors: Ricardo Moratelli, Cl?¡udio de Moraes Andrade and Jorge Lu?s Azevedo de Armada
We developed a procedure to obtain fibroblasts from bat skin. A small fragment of the ear is removed under ether anesthesia. This material is then cut up into small pieces and cultured in standard cell culture media. Very good quality chromosome preparations for cytogenetic studies are obtained in about three weeks. Secondary .. Read More»

Molecular cytogenetics in metaphase and interphase cells for cancer and genetic research,diagnosis and prognosis. Application in tissue sections and cell suspensions
Authors: Maria M?¼hlmann
As the pioneer among molecular cytogenetics techniques, fluorescence in situ hybridization (FISH) allows identification of specific sequences in a structurally preserved cell, in metaphase or interphase. This technique, based on the complementary double-stranded nature of DNA, hybridizes labeled specific DNA (probe). The probe.. Read More»
