Ovarian Abscess With Spontaneous Vaginal Drainage.

The occurrence of a rare ovarian abscess, spontaneously drained through the vagina after an abdominal hysterectomy is described. The treatment was an oophorectomy. The various forms of primary ovarian abscess are discussed in connection with these observations. This case illustrates the need for adequate manipulation of the gonad during pelvic surgery in order to avoid parenchymal contamination and the subsequent formation of such abscesses.11561596159

Fine-needle Aspiration Biopsy For Breast Lesions: A Comparison Between Two Devices For Obtaining Cytological Samples

Context and Objective: Fine-needle aspiration biopsy has been accepted worldwide for breast lesions. However, some questions remain, including the appropriateness of the puncture method. The objective of this work was to compare aspirates obtained by the auto-vacuum device and by the syringe pistol holder. Design and Setting: Randomized trial for validation of diagnostic method, at Hospital das Clinicas do Universidade Federal de Goiás and Hospital Araújo Jorge, Goiânio. Methods: 351 patients presenting breast lumps underwent fine-needle aspiration biopsy, either with the auto-vacuum device or the syringe pistol holder. A single cytopathologist analyzed all of the cytology slides. The rates of insufficient material, cellularity, cell distortion and background hemorrhage were evaluated. Results: The percentages of insufficient material were 16% and 22% (p = 0.18), for the auto-vacuum and pistol aspirates, respectively. Good cellularity was seen in 34% of autovacuum and 29% of pistol samples (p = 0.4). Cell distortion was seen in 31 and 26 cases, respectively (p = 07). Background hemorrhage occurred in 63 (35%) and 54 cases (31%) (p = 0.2), for auto-vacuum and pistol. The sensitivity was 88% and 86%; specificity 99% and 100%, positive predictive value 96% and and 100%, negative predictive value 96% and 95% and total occuracy 76% and 75% for the auto-vacuum and pistol, respectively. Conclusion: The results obtained from the two fine-needle aspiration biopsy methods were equivalent. Therefore, the auto-vacuum device is a good option for obtaining aspirates for cytology.1236271276Catania, S., Ciatto, S., Breast cytology: Instruments and technique (1992) Breast Cytology in Clinical Practice, pp. 11-60. , In: Ciatto S, editor.

Correlações genéticas e fenotípicas em duas populações de milho (Zea mays L.) braquítico e suas implicações no melhoramento do teor de óleo no grão

Coeficientes de correlações genéticas e fenotípicas foram estimados entre os caracteres: altura da planta (AP); altura da espiga (AE); peso de espigas (PE) e teor de óleo (TO). As estimativas foram obtidas para duas populações braquíticas de milho (Piranão VD-2 e Piranão VF-1), baseado em espiga por fileira, utilizando-se testemunha intercalar, onde a cada duas progênies plantava-se uma fileira do híbrido simples AG 305-B. Os valores das correlações genéticas aditivas encontradas entre os caracteres altura da planta, altura da espiga e peso de espigas, foram todos positivos. Para o caráter teor de óleo, quando correlacionado com os demais caracteres, os valores das correlações obtidos foram negativos nas duas populações, exceção feita ao peso de espiga correlacionada com teor de óleo, na população Piranão VD-2, cujo valor foi positivo e próximo de zero. As respostas correlacionadas obtidas entre os caracteres, quando a seleção é praticada para o caráter teor de óleo e vice versa, independente do método de seleção empregado, mostram que a seleção para teor de óleo leva a modificação na estrutura da planta, para as duas populações.Genetic and phenotypic correlations were estimated among the characteristics: plant height (AP), ear height (AE), ear weight (PE) and oil content (TO). The estimates were obtained for two brachytic maize populations (Piranão VD-2 e Piranão VF-1), based on the ear to row having an intercalated tester where at each two progenie rows had one row of the single hybrid Ag-305-B used as a tester. The additive genetic correlations found between plant height, ear height and ear weight, were all positives. When the oil content was correlated with ear weight, plant and ear height, negative correlation values were observed in both populations, exception done for oil content and ear weight in the Piranão VD-2 population, which value was positive and near to zero. The correlated genetic response found are suggesting that when selection is done for oil content, in both population will have some changing with the plant phenotype, mainly for plant and ear height

AVALIAÇÃO NUTRITIVA DE FENOS DA PASTAGEM NATURAL DO PARANÁ

Fenos de pastagem natural do Paraná colhidos durante o verão nos municípios de Ponta Grossa, Guarapuava e Tibagi, foram avaliados pela composição química, determinação dos coeficientes de digestibilidade e consumo voluntário com ovinos. Baseados na composição química, os valores encontrados foram semelhantes para os três fenos estudados. No entanto, o feno de Guarapuava apresentou valores mais elevados em FDN e lignina. Entre os coeficientes de digestibilidade, somente o da proteína bruta e do FDN não apresentaram diferença significativa entre os locais (P>0,05). Para a digestibilidade da matéria seca e energia bruta, o feno de Ponta Grossa mostrou-se superior ao de Tibagi. No consumo de matéria seca, proteína e energia digestíveis, não houve diferença significativa (P>0,05) entre locais, mas em relação a energia líquida de manutenção o feno de Ponta Grossa diferiu significativamente do feno de Tibagi (P0.05). As far as digestibility of the dry matter and gross energy are concerned, the hay of Ponta Grossa showed superior qualities when compared with the Tibagi one. No significant differences (P>0.05) were found between all the hays studied. However, in regard to liquid maintenance energy, the Ponta Grossa hay differed significantly from the Tibagi hay (

Timing of insemination and fertility in dairy and beef cattle receiving timed artificial insemination using sex-sorted sperm

AbstractThe objective was to evaluate the effects of timing of insemination and type of semen in cattle subjected to timed artificial insemination (TAI). In Experiment 1, 420 cyclic Jersey heifers were bred at either 54 or 60 h after P4-device removal, using either sex-sorted (2.1 × 106 sperm/straw) or non-sorted sperm (20 × 106 sperm/straw) from three sires (2 × 2 factorial design). There was an interaction (P = 0.06) between time of AI and type of semen on pregnancy per AI (P/AI, at 30 to 42 d after TAI); it was greater when sex-sorted sperm (P < 0.01) was used at 60 h (31.4%; 32/102) than at 54 h (16.2%; 17/105). In contrast, altering the timing of AI did not affect conception results with non-sorted sperm (54 h = 50.5%; 51/101 versus 60 h = 51.8%; 58/112; P = 0.95). There was an effect of sire (P < 0.01) on P/AI, but no interaction between sire and time of AI (P = 0.88). In Experiment 2, 389 suckled Bos indicus beef cows were enrolled in the same treatment groups used in Experiment 1. Sex-sorted sperm resulted in lower P/AI (41.8%; 82/196; P = 0.05) than non-sorted sperm (51.8%; 100/193). In addition, there was a tendency for greater P/AI (P = 0.11) when TAI was performed 60 h (50.8%; 99/195) versus 54 h (42.8%; 83/194) after removing the progestin implant. In Experiment 3, 339 suckled B. indicus cows were randomly assigned to receive TAI with sex-sorted sperm at 36, 48, or 60 h after P4 device removal. Ultrasonographic examinations were performed twice daily in all cows to confirm ovulation. On average, ovulation occured 71.8 ± 7.8 h after P4 removal, and greater P/AI was achieved when insemination was performed closer to ovulation. The P/AI was greatest (37.9%) for TAI performed between 0 and 12 h before ovulation, whereas P/AI was significantly less for TAI performed between 12.1 and 24 h (19.4%) or >24 h (5.8%) before ovulation. In conclusion, sex-sorted sperm resulted in a lesser P/AI than non-sorted sperm following TAI. However, improvements in P/AI with delayed time of AI were possible (Experiments 1 and 3), and seemed achievable when breeding at 60 h following progestin implant removal, compared to the standard 54 h normally used in TAI protocols

Maximally-localized Wannier functions for entangled energy bands

We present a method for obtaining well-localized Wannier-like functions (WFs) for energy bands that are attached to or mixed with other bands. The present scheme removes the limitation of the usual maximally-localized WFs method (N. Marzari and D. Vanderbilt, Phys. Rev. B 56, 12847 (1997)) that the bands of interest should form an isolated group, separated by gaps from higher and lower bands everywhere in the Brillouin zone. An energy window encompassing N bands of interest is specified by the user, and the algorithm then proceeds to disentangle these from the remaining bands inside the window by filtering out an optimally connected N-dimensional subspace. This is achieved by minimizing a functional that measures the subspace dispersion across the Brillouin zone. The maximally-localized WFs for the optimal subspace are then obtained via the algorithm of Marzari and Vanderbilt. The method, which functions as a postprocessing step using the output of conventional electronic-structure codes, is applied to the s and d bands of copper, and to the valence and low-lying conduction bands of silicon. For the low-lying nearly-free-electron bands of copper we find WFs which are centered at the tetrahedral interstitial sites, suggesting an alternative tight-binding parametrization.Comment: 13 pages, with 9 postscript figures embedded.

Endocrine disruptive action of diclofenac and caffeine on Astyanax altiparanae males (Teleostei: Characiformes: Characidae)

Diclofenac (DCF) and caffeine (CAF) are persistent pharmaceuticals that occur in mixtures in the aquatic ecosystems causing effects in the reproductive physiology of aquatic organisms. This study evaluated the physiological reproductive responses of Astyanax altiparanae males exposed to nominal concentrations of DCF (3.08 mg L− 1) and CAF (9.59 mg L− 1) separately and combined, for 96 h. The steroids profile, estrogenic biomarker vitellogenin (vtgA), testes and liver morphology, and also mortality of males were assessed. DCF and CAF degradation was 5% of the initial concentration for 24 h. The LC50 of the DCF and CAF were 30.8 mg L− 1 and 95.9 mg L− 1, respectively. Males exposed to DCF and CAF exhibited a reduction of 17β-Estradiol (E2) concentration compared to control (CTL). Similarly, testosterone (T) was also reduced in the DCF treatment, but this response was not observed in 11-Ketotestosterone (11-KT). Males exposed to DCF + CAF combined did not exhibit differences in T, E2 and 11-KT steroids. The vtgA gene expression and the sperm concentration did not change among the treatments. Moreover, acute exposure revealed a hypertrophy of hepatocytes cells in the DCF and DCF + CAF treatments. In conclusion, DCF and CAF, isolated, exhibit an endocrine disruptive activity in A. altiparanae male, an opposite response observed with the mixture of both compounds that abolishes the endocrine disruptive effects. DCF seems to be more toxic for this species, altering also hepatocytes morphology.Fil: Godoi, Filipe G.A.. Universidade de Sao Paulo; BrasilFil: Muñoz Peñuela, Marcela.

Comment on "Critique of q-entropy for thermal statistics" by M. Nauenberg

It was recently published by M. Nauenberg [1] a quite long list of objections about the physical validity for thermal statistics of the theory sometimes referred to in the literature as {\it nonextensive statistical mechanics}. This generalization of Boltzmann-Gibbs (BG) statistical mechanics is based on the following expression for the entropy: S_q= k\frac{1- \sum_{i=1}^Wp_i^q}{q-1} (q \in {\cal R}; S_1=S_{BG} \equiv -k\sum_{i=1}^W p_i \ln p_i) . The author of [1] already presented orally the essence of his arguments in 1993 during a scientific meeting in Buenos Aires. I am replying now simultaneously to the just cited paper, as well as to the 1993 objections (essentially, the violation of "fundamental thermodynamic concepts", as stated in the Abstract of [1]).Comment: 7 pages including 2 figures.

AVALIAÇÃO DE CULTIVARES DE MILHO PARA PRODUÇÃO DE SILAGEM DE ALTA QUALIDADE

Na safra 97/98, no campo experimental da UFPR em Palotina - PR, foi realizado um ensaio a campo com o objetivo de observar o desempenho de 12 cultivares de milho (Zea mays L.), utilizadas para ensilagem. Foram avaliados os seguintes parâmetros: porcentagem de proteína bruta (PB), de fibra em detergente ácido (FDA), de fibra em detergente neutro (FDN) e de nutrientes digestíveis totais (NDT). Também foram estimados os valores da ingestão de matéria seca (IMS), da digestibilidade da matéria seca (DMS) e do valor relativo nutricional (VRN). Os resultados não mostraram diferenças significativas (p>0,05) entre cultivares, quanto aos parâmetros: porcentagem de proteína bruta (PB), de fibra em detergente ácido (FDA) e de digestibilidade da matéria seca (DMS). Nos outros parâmetros observou-se diferenças significativas (p0.05) were found between the cultivars in regard to crude protein, acid detergent fiber and dry matter digestibility. On the other hand, significant differences (
