Abstract: the aim of this study was to test if serological distinction between patients with active and inactive neurocysticercosis (ncc), could be accomplished by the recognition of immunodominant peptides in total saline antigenic extract of taenia solium metacestodes by igg antibody in cerebrospinal fluid (csf) and serum paired samples. csf and serum samples of 10 each, active ncc patients, inactive ncc, and individuals with other neurological disorders, were used to recognize the antigenic peptides by western blot (wb). in the active ncc the 28-32 and 39-42 kda peptides were more frequently detected in csf than in sera (p < 0.05). the 47-52, 64-68, and 70 kda antigens showed high frequencies in both samples from patients with active ncc. all the csf samples of inactive ncc and other neurological disorder (control) patients tested negative, while serum samples from these last two groups recognized mainly the 80, 86, 95, and 98 kda bands. this finding eliminates the use of the high molecular weigh bands (> 80 kda) for diagnosis of ncc. the final conclusions were that the difference between active and inactive ncc may be done with the detection of peptides only in the csf samples and that the 47-52, 64-68, and 70 kda bands may be included as specific markers for active ncc when detected in csf samples by wb using total saline extract of t. solium metacestode.

Abstract: the pepper species c. chinense has been considered one of the most important resistance sources to powdery mildew capsicum spp. however, the inheritance in this species was unknown. the purpose of this work was to study its reaction inheritance. two powdery mildew resistant parents, 'pimenta cheiro' 1 and pi 152225 and two moderately susceptible ones, 'pimenta doce' ih-1761 and 'pimenta índio', were used to obtain three f1 and their respective f2 generations: 'pimenta doce' ih-1761 ′ 'pimenta cheiro' 1, 'pimenta índio' ′ pi 152225 and 'pimenta doce' ih-1761 ′ pi 152225. the powdery mildew epidemy was natural using inoculum from a highly-sporulating susceptible pepper host. powdery mildew host reaction evaluations were carried out during the fruiting stage using a rating system based on disease severity scales varying from 1 (resistant) to 5 (highly susceptible). the experimental design was completely randomized. the following genetic parameters were estimated: gene action, heritability coefficient and expected selection gain in the f3 generation. the transgressive segregation in f2 indicated oligogenic inheritance. results show the presence of additive, dominant, and epistatic gene action. the dominant and epistatic effects detected in crosses presented negative values, tending towards susceptibility. the heritability and selection gain estimates were moderate, with values of 35.5% and 1.7% for 'pimenta doce' ih 1761 ′ 'pimenta cheiro' 1, from 50.4% to 3.5% for 'pimenta índio' ′ pi 152225, and 49% and 2.7% for the 'pimenta doce' ih 1761 ′ pi 152225 crosses, respectively. these gene action results are favorable for breeding programs and exploration of hybrids.

Abstract: The aim of this study was to evaluate the efficiency of the postpartum bovine endometritis treatment by intrauterine and intramuscular administration of tetracycline. Forty six cross bred cows diagnosed by gynecological exam with postpartum endometritis were assigned randomly in two treatments: G1 (n=21) - animals were treated with one intramuscular (IM) dose of tetracycline (20 mg/Kg of body weight), while in G2 (n=25) animals were treated with one intrauterine (IU) dose of tetracycline (30 mg/Kg of body weight). No difference (p>0.05) was observed in the recovery rate between the two treatments (61.9 X 76.0%, G1 and G2, respectively). The interval from treatment until first estrous was 33.9±22.6 versus 14.8 ±10.9 days (P<0.05) and until first service was 54.7 ± 33.9 versus 27.2 ± 20.3 days (P<0.05;) for G1 and G2, respectively. No difference (p>0.05) was observed in the number of services per conception between G1 (1.54) and G2 (1.3). The treatment cost was lower for the G1 (U$ 3.51 versus U$ 5.00). Although not to have had differences in the clinical recovery rate, the use of the oxitetracycline managed for way IU in the postpuerperal treatment of endometrites in cows revealed more efficient in the reduction of the interval between the treatment and first heat and first insemination, beyond presenting lower cost that the treatment with oxitetracycline managed for way IM KEY WORDS: Bovine, postpartum endometritis, intrauterine, intramuscular, oxitetracicline. Este trabalho teve por objetivo comparar a eficiência do uso da oxitetracilina, administrada pelas vias intramuscular (IM) e intrauterina (IU), no tratamento de endometrites em vacas no período pós-puerperal. Foram utilizados 46 animais mesti os que apresentaram quadro clínico de endometrite, distribuídos aleatoriamente em dois tratamentos: G1 (n=21) – tratado com uma dose de 30 mg/Kg PV de oxitetraciclina por via IM, e G2 (n=25) – uma infus o de 20 mg/Kg PV de oxitetraciclina por via IU. N o houve diferen a (p>0,05) na taxa de recupera o dos animais, 61,9% e 76,0% para G1 e G2, respectivamente. O intervalo entre o tratamento e o primeiro estro (P<0,05) foi de 33,9 ± 22,6 versus 14,8 ± 10,9 dias, e do tratamento à primeira insemina o artificial (P<0,05) foi de 54,7 ± 33,9 versus 27,2 ± 20,3 dias para G1 e G2, respectivamente. N o houve diferen a entre o número de servi os por concep o entre G1 (1,54) e G2 (1,30). O tratamento pela via IU apresentou menor custo, quando comparado ao IM (P<0,05; R$ 6,54 e R$ 9,3, respectivamente). Apesar de n o ter havido diferen as na taxa de recupera o clínic

Abstract: this study had the following objects: to evaluate the immediate and latent effects of drying-air temperature and compare the influence of two types of seed packaging on the physiological quality of seeds of the yellow passion fruit. tests were conducted employing four levels of drying-air temperature (ambient temperature under shade, 30, 35, and 40 oc), one level of drying-air airflow (48 m3 min-1 m-2), and initial and final seed moisture contents of 35 and 10% w.b., respectively. drying runs were performed in thin layers in a prototype laboratory drier with an upward airflow design. the physiological quality of the seeds was assessed through vigour and standard germination tests. upon removal from the drier, seeds were cooled to ambient air temperature, placed in glass containers and polyethylene bags and stored in a controlled temperature chamber at 15±1 oc for 90 and 180 days. results showed that drying-air temperature had no significant effect on passion fruit seeds germination. storage priods of 90 and 180 days produced seeds with the same vigour based on the count made at the seventh day. also, the final germination count was not affected by storage time. results revealed that both seed vigour and germination were the same regardless of whether they were dried at ambient temperature under shade or under controlled temperature in the range from 30 to 40 oc.

Abstract: Background: The present work aims to characterize the profile of patients with stroke treat at a hospital located in the Region of the Mata of Minas Gerais, Brazil, considering the findings of the clinical vocal tract, kind of stroke, age and gender of such patients. Methodology: To obtain data, the clinical profile of 133 patients with a clinical or tomography diagnosis of stroke was analyzed, and the results were presented in percentage. For quantitative data average and analysis the tests were done with associations that held χ2 test, and for significance it was considered p < 0.05. Results: From the total of patients, 63 were women, accounting for 47.4% and the other 52.6% were males. Clinically, they were characterized with the highest percentage for ischemic stroke (89.4%) compared to the hemorrhagic type (10.6%). Most of them were referred for computed tomography (86.5%) and remained hospitalized for an average of 6.496 ± 7.372 days. Similar percentages were obtained in the analysis of the population in question, when considering if they had (54.1%) or not (49.6%) any damage in their speech, language skills or swallowing. There were different types of disabilities in patients with stroke. Men with an average age of 69.8 ± 13.9 presents mostly ischemic stroke, and the majority of patients with stroke had hemiplegia and abnormalities of the vocal tract, dysphasia, and aphasia. While older patients had an ischemic stroke and were presented with left hemiplegia, the younger ones suffered from hemorrhagic strokes that caused a disability characterized as right hemiplegic. Conclusion: Our results show important conclusions regarding the clinical evolution of the vocal tract of patients who suffered strokes during the period of the analysis, being useful for better comprehension of how the vocal tract from these patients evolved according to the kind of stroke, sex and age also allowing a contraposition with other future statistics periods available in literature. It can also be pointed out the difficulties in diagnosing the stroke and the concern with the immediate care, but not with its continuance or with its multidisciplinary approach, giving an evident life risk through dysphasia and the increase of permanent damage when there isn’t an appropriate work done with the patients.
