Surface ultrastructure of prestomal teeth of some flies in the families Calliphoridae, Muscidae and Sarcophagidae 总被引:1,自引:0,他引:1

Prestomal teeth of flies in the families Calliphoridae (Chrysomya pinguis, Chrysomya villeneuvi, and Chrysomya chani), Muscidae (Hydrotaea (= Ophyra) chalcogaster) and Sarcophagidae (Boettcherisca peregrina) were presented using scanning electron microscopy. The slight to deep bifurcation of the tips of their teeth were similarly observed in all species examined. The anatomical feature of prestomal teeth of the flies examined may contribute to the understanding of their feeding behavior and the medical importance of their role in the future. 相似文献

Factor XIII (FXIII) deficiency is a very rare severe autosomal bleeding disorder with a frequency of 1:2,000,000 in the general population and only a few patients have been genetically characterized so far. We report a phenotype-genotype characterization of 10 unrelated Iranian patients. Two FXIII (transglutaminase) activity assays showed no FXIII activity, except a conserved residual activity in patients receiving prophylactic substitution treatment. FXIII antigen concentrations measured by two immunoassays were comparable. Genotype characterization identified four novel mutations (2 missense and 2 small deletions) and two previously reported missense mutations in the FXIII A subunit gene (F13A). Molecular modeling was carried out to reveal the structural consequences of the missense mutations, that caused the replacement of an arginine residue involved in the formation of structurally important extensive hydrogen-bonded network. The replacements [c.320G>A (p.Arg77His) in the beta-sandwich, c.868C>T (p.Arg260Cys), c.869G>A (p.Arg260His) and c.1236G>T (p.Arg382Ser) in the core domain] resulted in the loss or impairment of such H-bonded network. Energy decomposition analysis demonstrated that this situation leads to the instability and perhaps to the incorrect folding of the A subunit, that would explain the development of severe FXIII deficiency. 相似文献

Distribution and occurrence of blow flies of forensic importance was
performed during 2007 and 2008 in Chiang Mai and Lampang Provinces, northern
Thailand. Surveys were conducted in forested areas for 30 minutes using a sweep net
to collected flies attracted to a bait. A total of 2,115 blow flies belonging to six
genera and 14 species were collected; Chrysomya megacephala
(Fabricius) (44.7%), C. pinguis (Walker) (15.1%), C.
chani Kurahashi (9.3%), C. thanomthini Kurahashi &
Tumrasvin (0.3%); Achoetandrus rufifacies (Macquart) (10.5%),
A. villeneuvi (Patton) (2.2%); Lucilia papuensis
Macquart (2.2%), L. porphyrina (Walker) (12.4%), L.
sinensis Aubertin (0.7%); Hemipyrellia ligurriens
(Wiedemann) (1.3%), H. pulchra (Wiedemann) (0.1%);
Hypopygiopsis infumata (Bigot) (0.6%), Hy.
tumrasvini Kurahashi (0.2%) and Ceylonomyia nigripes
Aubertin (0.4%). Among them, C. megacephala was the predominant
species collected, particularly in the summer. The species likely to prevail in
highland areas are C. pinguis, C. thanomthini, Hy. tumrasvini, L.
papuensis and L. porphyrina. 相似文献

Impairment of Left Atrial Mechanics Is an Early Sign of Myocardial Involvement in Systemic Sclerosis
Adél Porpáczy Ágnes Nógrádi Dániel Kehl Maja Strenner Tünde Minier László Czirják András Komócsi Réka Faludi 《Journal of cardiac failure》2018,24(4):234-242
Background
Left ventricular (LV) diastolic dysfunction is common in systemic sclerosis (SSc). Less is known, however, about left atrial (LA) mechanics in this context. The aim of this study was to investigate the correlation between LV diastolic function and LA mechanics in SSc patients with the use of volumetric and 2-dimensional speckle tracking–derived strain techniques and to compare the results with those obtained in healthy subjects.Methods and Results
Seventy-two SSc patients and 30 healthy volunteers (H) were investigated. LV diastolic function was classified as normal (I), impaired relaxation (II), and pseudonormal pattern (III). LA reservoir (H: 51.8?±?7.4%; I: 45.1?±?8.1%; II: 42.2?±?6.6%; III: 36.6?±?7.3%; analysis of variance: P?<?.001) and contractile strain (H: 24.8?±?4.9%; I: 18.2?±?4.4%; II: 21.5?±?2.8%; III: 16.8?±?3.6%; P?<?.001) already showed significant worsening in SSc patients with preserved LV diastolic function compared with healthy subjects. LA conduit strain (H: 27.1?±?4.6%; I: 26.9?±?5.7%; II: 20.6?±?6.1%; III: 19.5?±?5.3%; P?<?.001) was preserved in this early phase. Further deterioration of reservoir strain was pronounced in the pseudonormal group only. LA contractile strain increased significantly in the impaired relaxation group and then decreased with the further worsening of the LV diastolic function. Regarding phasic volume indices, the differences between groups were not always statistically significant.Conclusion
LA mechanics strongly reflects the changes in LV diastolic function in SSc. On the other hand, strain parameters of the LA reservoir and contractile function already show significant worsening in SSc patients with preserved LV diastolic function, suggesting that impairment of the LA mechanics is an early sign of myocardial involvement in SSc. 相似文献8.
In this paper, an algorithm for detection of suspicious masses from mammographic images is presented. The proposed algorithm was tested on a database of 61 mammograms on which masses had previously been marked by experienced radiologists. Results show that the proposed method exhibits for mass detection, a sensitivity of 95.91%. The area under receiver operating characteristic (ROC) Az was 0.946 when enhancement of the original image was performed before detection and 0.938 otherwise. Furthermore in some cases, we could detect some masses that the radiologists were not able to mark out. 相似文献

Although increasingly complex models have been proposed in mediation literature, there is no model nor software that incorporates the multiple possible generalizations of the simple mediation model jointly. We propose a flexible moderated mediation model allowing for (1) a hierarchical structure of clustered data, (2) more and possibly correlated mediators, and (3) an ordinal outcome. The motivating data set is obtained from a European study in nursing research. Patients' willingness to recommend their treating hospital was recorded in an ordinal way. The research question is whether such recommendation directly depends on system‐level features in the organization of nursing care, or whether these associations are mediated by 2 measurements of nursing care left undone and possibly moderated by nurse education. We have developed a Bayesian approach and accompanying program that takes all the above generalizations into account. 相似文献

The efficacy of crude pineapple juice obtained from Ananus comosus in digesting fish for the harvesting of trematode metacercariae was investigated. No significant difference was found between the total number of metacercariae detected from fish (Cirrhina jullieni) digested by acid pepsin and those digested by freshly prepared pineapple juice that was kept for 15 days at a temperature of either -4 degrees C or -75 degrees C. However, fewer metacercariae were found when using juice that had been kept for more than 30 days. This study showed that freshly prepared pineapple juice kept frozen for 15 days could be used instead of commercial acid pepsin to digest fish for harvesting metacercariae, some of which could be used for further biological studies. 相似文献
