Eight polymorphic microsatellite markers were developed for the grasshopper Mioscirtus wagneri. Polymorphism at these loci was evaluated in 25 individuals from Central Spain. The number of alleles per locus ranged from
3 to 9 and their observed and expected heterozygosities ranged from 0.28 to 0.80 and 0.25 to 0.84, respectively. All genotypic
frequencies conformed to Hardy–Weinberg equilibrium expectations, with no evidence of genotypic linkage disequilibrium between
any pair of loci. These loci will be highly useful for the study of the population genetic structure and diversity of this
grasshopper species forming highly fragmented populations of great conservation concern. 相似文献

In samples of Arratia and Gernika populations, who are indigenous Basque ethnic groups, the frequency of the GLOI1 allele was respectively 0.457 +/- 0.042 and 0.459 +/- 0.041. Four samples belonging to Castilian populations were also studied. The results of this work suggested homogeneity between the Spanish and other populations. 相似文献

Short-course preoperative radiotherapy (RT) is widely used in northern Europe for locally advanced resectable rectal cancer, but its role in the era of advanced imaging techniques is uncertain. Here, we reviewed articles and abstracts on SCRT published from 1974 through 2013 with the goal of identifying patients who might be best suited for short-course RT. We included relevant articles comparing surgery with or without preoperative radiation published before and after the advent of total mesorectal excision. We also analyzed two randomized trials directly comparing short-course RT with conventionally fractionated chemoradiation (the Polish Colorectal Study Group and the Trans-Tasman Radiation Oncology Group) that compared short-course RT with conventional chemoradiotherapy. We conclude from our review that short-course RT can be generally applied for operable rectal cancer and produces high rates of pelvic control with acceptable toxicity; it reduces local recurrence rates but does not increase overall survival. SCRT seems to be best used for tumors considered “low risk,” i.e., those that are >5 cm from the anal margin, without circumferential margin involvement, and involvement of fewer than 4 lymph nodes. Whether sequential chemotherapy can further improve outcomes remains to be seen, as does the best time for surgery (immediately or 6–8 weeks after RT). We further recommend that selection of patients for short-course RT should be based on findings from magnetic resonance imaging or transrectal ultrasonography. 相似文献

- Semiochemicals are powerful tools for the surveillance and suppression of forest insects. Although the literature on the chemical ecology of and use of semiochemicals to manage the Cerambycidae is growing, little is known about the chemical ecology of Cerambycidae fauna in Peru.
- Trapping studies that screen known attractants in off-shore mitigation programs can provide valuable baseline knowledge to inform management of species introduced outside their native range.
- Known Cerambycidae pheromones were screened for activity in a year-long field study in Peru to look for activity in the local Cerambycidae fauna.
- The most frequently captured species were Megacyllene andesiana (Casey), Oreodera bituberculata Bates, Aegomorphus longitarsis (Bates) and Discopus eques Bates.
- The activity period of A. longitarsis, O. bituberculata and D. eques occurred in mid-September 2020 and for M. andesiana occurred in early October 2020.
- Responses to anti-2,3-hexanediol, fuscumol and fuscumol acetate by M. andesiana, O. bituberculata and D. eques were observed.
- We observed antagonism of the responses of M. andesiana, O. bituberculata and D. eques when anti-2,3-hexanediol, fuscumol and fuscumol acetate were tested in blends.

Phylogenetic studies were performed on some Gram-positive catalase-negative cocci from human clinical sources of uncertain taxonomic position. 16S rRNA sequence analysis demonstrated that the isolates represent a hitherto unknown line of descent within the low G + C Gram-positive bacteria for which the name Globicatella sanguis gen.nov., sp.nov. is proposed. 相似文献

The abundance of early fossil humans in African sites ceases at dates around 1.3MaBP; there is almost none until nearly 0.8MaBP.
Again these are scarce until less than 0.5 Ma. Most of Homo erectus fossils in Java are dated between c.1.3 and 0.70Ma; just
a few fossil humans are known in Eurasia for this time span. Questions arise on eventual environmental constraints, that may
have influenced evolutionary crises of human populations, but also on geographic conditions adverse to fossilization processes
and/or site formation. Records on climate variables, vegetation, sea level, sedimentary conditions and tectonic behavior in
regions of the Old World are collected, and correlation traced back in time slices. Continental accretion is related to end
of sedimentation in African basins; repeated compressive tectonic activity negatively affected preservation of both fossils
and occupation sites widely, before and immediately after the M/B reversal. Lithic artefact assemblages, although derived,
are understood as evidence of human occupation in the studied interval. Human populations are exspected to be affected by
environmental changes, small, and scattered. Origin of Homo sapeins and divergence of preneandertalians are driven back to
those times. Ancestorship to the latter is found probably in African fossils of that time span. Modern traits found in the
Atapuerca-TD6 sample and the preceeding considerations urge research on humans and their movements intra- and intercontinental
around 1 MaBP. 相似文献
