Population surveys of Culex pipiens quinquefasciatus carried out in 1991 and 1999 were compared with data collected in 1990 before the beginning of the control program against this mosquito. Larval samples collected in 1999 displayed resistance to the four tested insecticides: permethrin, propoxur, temephos, and chlorpyrifos. Temephos resistance ratio at LC50 (RR50) ranged between 8.1- and 42-fold compared with 2.9- and 4.6-fold in 1990, and chlorpyrifos RR50 ranged between 8.6- and 123-fold compared with 6.4- and 19-fold in 1990. This increased resistance to organophosphorus insecticides was associated with a sharp decrease of susceptible genotypes at two loci (Ester and ace-1), as well as to an allele replacement at the Ester locus. 相似文献

There are variety of surgical methods in treating trigeminal neuralgia. They can all be devided in two large groups: less invasive procedures and decopmressive procedures in the region of pontocerebelar angle. Peripheral neurectomy, exeresis or avulsion of peripheral branches of trigeminal nerv are methods for elderly patients with serious cardiopulmonal disturbances. We performed avulsion of peripheral branches at 58 patients, all older than 60 years. In 32 patients we did avulsion of only one of three branches of trigeminal nerv, while in 26 patients the combined avulsion of two branches was performed. There were no postoperative complications. 相似文献

The authors report a human sperm suspension method to assess quantitatively the stainability of the spermatozoa chromatin. Analysis of 15 ejaculates demonstrated the existence of a constant percentage of stained DNA in different ejaculated spermatozoa. The condensed chromatin stainability was then compared to the in vitro decondensed chromatin stainability with the finding of an increased uptake of fluorochrome in relation with the nuclear chromatin decondensation. The quantitative spermatozoa chromatin stainability and its decondensation aptitude may be of importance in sperm physiology. 相似文献

The present study has been carried out to investigate the effect of aqueous extract of shallot (Allium ascalonicum) and garlic (Allium satium) on the fasting insulin resistance index (FIRI) and intraperitoneal glucose tolerance test (IPGTT) of fructose-induced insulin resistance rats. Male albino Wistar rats were fed either normal or high-fructose diet for a period of eight weeks. Fasting blood glucose level, fasting blood triglyceride level, FIRI, and the area under the glucose tolerance curve were significantly elevated in fructose-fed animals. Fructose-induced insulin resistance rats treated by aqueous shallot or garlic extract (500 mg/kg body weight/day, i.p.) for duration of eight weeks. Control animals only received normal saline (0.9%). The results showed that neither shallot nor garlic extracts significantly altered the FIRI and the IPGTT at the fourth week after treatment. The fasting blood glucose in fructose-induced insulin resistance animals has been significantly decreased in 8-week treated animals by both shallot and garlic extracts. Shallot extract administration, but not garlic extract, for a period of eight weeks can significantly improve the intraperitoneal glucose tolerance and diminish the FIRI. These results indicate that shallot and garlic extracts have a hypoglycemic influence on the fructose-induced insulin resistance animals and aqueous shallot extract is a stronger hypoglycemic agent than the garlic extract. 相似文献

Globally, hepatocellular carcinoma (hcc) is the third most common cause of death from cancer, after lung and stomach cancer. The incidence of hcc in Canada is increasing and is expected to continue to increase over the next decade. Given the high mortality rate associated with hcc, steps are required to mitigate the impact of the disease. To address this challenging situation, a panel of 17 hcc experts, representing gastroenterologists, hepatologists, hepatobiliary surgeons, medical oncologists, pathologists, and radiologists from across Canada, convened to provide a framework that, using an evidence-based approach, will assist clinicians in optimizing the management and treatment of hcc. The recommendations, summarized here, were developed based on a rigorous methodology in a pre-specified process that was overseen by the steering committee. Specific topics were identified by the steering committee and delegated to a group of content experts within the expert panel, who then systematically reviewed the literature on that topic and drafted the related content and recommendations. The set of recommendations for each topic were reviewed and assigned a level of evidence and grade according to the levels of evidence set out by the Centre for Evidence-based Medicine, Oxford, United Kingdom. Agreement on the level of evidence for each recommendation was achieved by consensus. Consensus was defined as agreement by a two-thirds majority of the 17 members of the expert panel. Recommendations were subject to iterative review and modification by the expert panel until consensus could be achieved. 相似文献

Most tunneled catheters can be easily removed after the retention cuff is dissected. Occasionally, these catheters can become resistant to removal even after application of potentially hazardous forceful traction. In addition, an infected catheter may cause life-threatening septicemia. Several methods have been described for their extraction, some of which may be available only in tertiary-care facilities. The present report describes the successful extraction of five such "stuck" catheters by using a recently described technique of endoluminal dilation. The technique appears safe and straightforward and can be performed in any interventional suite while allowing preservation of venous access. 相似文献

Background
Numerous cementless femoral stem design variations are in clinical use. Because initial implant instability and micromotion are associated with aseptic loosening of the femoral component, migration analysis provides an early assessment of implant survivorship. 相似文献10.
