Genetic inheritance of resistance to Bacillus thuringiensis var kurstaki (BTK) was examined in a diamondback moth (Plutella xylostella) population collected from the Melaka region of Malaysia. A BTK‐selected sub‐population (BTK‐SEL) which was more than 100‐fold resistant to BTK compared with a susceptible (ROTH) population of P xylostella was used with standard reciprocal crosses and back‐crosses between ROTH and BTK‐SEL. Logit regression analysis of F 1 reciprocal crosses indicated that BTK resistance was inherited as an incompletely recessive autosomal trait and controlled by a single locus. In contrast, other studies have shown that resistance to Cry1Ac is inherited as an incompletely dominant autosomal trait in a Cry1Ac‐selected sub‐population of the same Melaka population. The frequency of the allele responsible for resistance decreased without exposure to insecticide in the laboratory. © 2000 Society of Chemical Industry 相似文献

Using basic principles of stereographic projection,block theory and rock mechanics,this paper tries to find a simple and easy method for determination of an optimum scheme for bolting unstable rocks on a rock slope in design of slope engineering.finally, examination and analysis is made of the completed project for bolting the unstable,high and steep rock slope on the campus of Chongqing University. 相似文献

AIM:To construct a subtracted cDNA library of differentially expressed genes in human unstable angina lymphocytes.METHODS:Suppression subtractive hybridizations (SSH) were performed between the patients with unstable angina pectoris and stable angina pectoris. Lymphocyte RNA, the obtained forward and reverse cDNA fragments were directly inserted into T/A cloning vector and transformed into E.coli JM 109 to construct a subtractive cDNA library. The inserting fragments were screened by blue and while blot screening and bacterium liqulid PCR.RESULTS:Each subtractive cDNA library contained more than 2000 positive bacteria clones. Most of them distributed between 200-600 bp inserts.CONCLUSION:The library is efficient and lays solid foundation for screening and cloning new and specific expressed genes in unstable angina lymphocyte RNA. 相似文献

AIM: To study the inhibitory effect of high-dose Xuezhikang,administered before percutaneous coronary intervention (PCI) on inflammatory response induced by PCI in patients with unstable angina (UA).METHODS: All patients with UA in class Ⅲ and ⅡB according to Braunwald classification were considered for inclusion in the present study.Finally,196 patients received Xuezhikang treatment 72 h before coronary angiography and successfully performed PCI with elevated C-reactive protein (CRP) level (>3 mg/L) were randomised to 2 groups: 1.2 g/d of Xuezhikang as group A,or 2.4 g/d of Xuezhikang as group B.The levels of CRP were measured at baseline,after 3 days of therapy (before procedure) and 48 hours after PCI.The patients were followed-up for 6 months for major adverse coronary events and left ventricular ejection fraction.RESULTS: There was no significant difference in the mean CRP level among the two randomized groups (P>0.05),however,after three days of pharmacological treatment,there was significantly reduced CRP content in group A ［(5.44±1.57） mg/L vs （4.04±1.54） mg/L,P<0.05］ and in group B ［(5.42±1.36） mg/L vs （3.60±1.14） mg/L,P<0.05］ compared with admission.Measurements performed 48 hours after the procedure revealed a marked CRP level increase in group A (up to 9.22 mg/L±5.03 mg/L) and an obvious increase in groups B (up to 4.97 mg/L±1.75 mg/L,P<0.05) compared with pre-procedure.The serum level of CRP in B group was distinctly lower than that in A group before (P<0.05) and after the procedure (P<0.05),respectively.Major adverse coronary events during the 6-month clinical follow-up occurred less in group A than that in group B ［21/104 (20.2%) vs 9/92 (9.8%); patients,P<0.05］.Follow-up echocardiography revealed lower left ventricular ejection fraction in group A than that in group B (55.41%±10.93% vs 59.30%±9.99%,P<0.05).CONCLUSION: High-dose Xuezhikang therapy,administered before PCI,has better inhibition effect than low-dose on inflammatory response induced by PCI in patients with UA.Attenuation of inflammatory response may be crucial for the reduction of coronary events following invasive coronary interventions. 相似文献

为进一步完善经典控制论中的结构图简化规则，深入研究具有不稳定零极点对消的结构图等效问题。指出复杂结构图等效后，如果其等效式与其他环节存在不稳定零极点对消，则对消后系统的性质将发生改变，此时应保持原结构图而不做进一步的简化，仿真示例验证这一结论。 相似文献
