Background
The New World monkey (Platyrrhini) subfamily Pitheciinae is represented by the genera Pithecia, Chiropotes and Cacajao. In this work we studied the karyotypes of Pithecia irrorata (2n = 48) and Cacajao calvus rubicundus (2n = 45 in males and 2n = 46 in females) by G- and C-banding, NOR staining and chromosome painting using human and Saguinus oedipus whole chromosome probes. The karyotypes of both species were compared with each other and with Chiropotes utahicki (2n = 54) from the literature. 相似文献82.

Entomopathogenic nematodes are natural enemies and effective biological control agents of subterranean insect herbivores. Interactions between herbivores, plants, and entomopathogenic nematodes are mediated by plant defense pathways. These pathways can induce release of volatiles and recruit entomopathogenic nematodes. Stimulation of these plant defense pathways for induced defense against belowground herbivory may enhance biological control in the field. Knowledge of the factors affecting entomopathogenic nematode behaviour belowground is needed to effectively implement such strategies. To that end, we explore the effect of elicitor, elicitor dose, mechanical damage, and entomopathogenic nematode release distance on recruitment of entomopathogenic nematode infective juveniles to corn seedlings. Increasing doses of methyl jasmonate and methyl salicylate elicitors recruited more entomopathogenic nematodes as did mechanical damage. Recruitment of entomopathogenic nematodes was higher at greater release distances. These results suggest entomopathogenic nematodes are highly tuned to plant status and present a strategy for enhancing biological control using elicitor-stimulated recruitment of entomopathogenic nematodes. 相似文献

Background
There is a concern about conservation of endangered species today. Among this species, the Leontopithecus (Lesson, 1840) is outstanding. Its population has been whirling reduced. So far the reproductive physiology of Leontopithecus has few studies, it is fundamental requisite to preserve this species. Obstetric sonography has become an essential method in reproductive management of primates.Method
This method is very helpful to detect early pregnancy and evaluate some deficiency of fetal growth. In this study, 14 pregnancies were monitored using real‐time abdominal sonography. During each evaluation, the number of fetus was recorded, gestational sac and heart beats were observed, and biparietal diameter was measured.Results
The results showed that abdominal sonography is a reliable method for observation of gross morphological changes during pre‐natal development and to estimate gestational age. No statistically differences were observed between twins and singletons. This study is the first investigation of pre‐natal growth in Leontopithecus. 相似文献84.
The use of combination drugs is very common in therapeutics as in the treatment of infectious diseases, cancer and heart failure but controversies about analysis of these interactions are frequent. The aim of the present work was to characterize the interaction between ouabain and 8-methoxy-3,9-dihydroxy coumestan (LQB93), a non-steroidal synthetic inhibitor of Na+,K+-ATPase, as well as the interaction between ouabain and ouabagenin, two cardiac glycosides sharing the same binding site. Inhibition of rat kidney Na+,K+-ATPase with increasing concentrations of the drugs alone or of mixtures of ouabain:ouabagenin and LQB93:ouabain in a fixed 1:4 ratio was performed. In other experiments, increasing concentrations of LQB93 (or ouabain) in the presence of a fixed concentration of ouabain (or ouabagenin) were used for determining the concentration pairs eliciting 50% inhibition in order to construct isobolograms. The mixture (experimental) curve for the ouabain:ouabagenin combination was superimposed on the additive (theoretical) curve indicating additivity, in accordance with the isobolographic analysis. On the other hand, the empirical curve for LQB93:ouabain (IC50 = 10.6 μM) was significantly shifted to the left in relation to the theoretical curve (IC50 = 30.7 μM) indicating synergism, further confirmed by the isobolographic analysis. As a conclusion, we show that the combination of a newly synthesized non-steroidal inhibitor and ouabain have a synergistic effect on Na+,K+-ATPase, further supporting a mechanism of inhibition different from ouabain. Present data also support the use of both the isobolograms and combination curves for the assessment of drug interactions occurring at the same molecular target, a situation poorly investigated. 相似文献

Chromosome studies in six wild-caught specimens of Cebus apella xanthosternos showed a distinctive chromosome pair number 11 that made it possible to distinguish this subspecies from other Cebus apella. The characteristic chromosome pair had intercalar heterochromatin unlike the “standard” chromosome type of Cebus apella and other species of the same genus, in which this chromosome pair shows a large, terminal, heterochromatic block. A comparison at the chromosomal level between different Cebus apella populations suggests that chromosome 11 in Cebus apella xanthosternos is a derived chromosome that has probably become fixed in this subspecies, either by selection or by drift in a small isolated population. 相似文献

When carrying out experiments on the production of the edible mushroom Pleurotus sajor-caju in the Laboratory of Edible Mushrooms, Universidade Federal de Lavras, Lavras, Brazil, in the second half of 2007, the presence of beetles later identified as belonging to the species Mycotretus apicalis was verified. This is the first recorded instance of this insect in cultures of P. sajor-caju in Brazil. The larvae and adults of this insect feed on the fruiting bodies of commercial harvests, resulting in reduction in mushroom quality. To provide evaluation of the injuries caused by these insects, substrates colonized by P. sajor-caju were infested with 4, 8, 16, 32 and 64 insects per block of substrate being the qualitative and quantitative losses then noted. Despite the lack of an observed decrease in biological efficiency, the injuries caused by these insects affected the commercial quality of the mushrooms, which may result in economic losses. The results showed that infestations of 32 insects per 0.8 kg of substrate led to a depreciation in the prices of mushrooms meant to be sold. 相似文献
