2013年6月28日 · In the present study, the PET PCR technique was used to create fluorescent primers for nucleic acid amplification of an 18S ssrRNA gene sequence specific to Cryptosporidium spp. The results (detection limit, PCR efficiency) were similar to a corresponding TaqMan assay targeting the same gene sequence.

2023年1月5日 · 间规聚丙烯，是高弹性的热塑性塑料，有良好的拉伸强度，它可以像乙丙橡胶那样进行硫化成为弹性体，机械性能优于一般不饱和橡胶。 从立体化学来看，SPP分子中含有甲基（—CH3）的碳原子分为两种不同构型且交替排列，如把主链拉伸，使主链的碳原子排列在主平面内，则所有的甲基（—CH3）交替排列在 主平面 的两侧。 SPP是高弹性的热塑性塑料，有良好的拉伸强度，它可以像 乙丙橡胶 那样进行硫化成为弹性体，机械性能优于一般不饱和橡胶。 知 …

ChIA-PET is a method for capturing genome-wide chromatin interactions that involve a protein of interest. First, protein-DNA interactions are stabilized by dual-cross-linking in cells. Then, nuclei are released by cell lysis and are sonicated to generate …

2003年7月1日 · We have analyzed the kinetics of SSP of thin PET chips at 250 °C in two different reaction environments: fast flowing nitrogen and high vacuum. The post polymerization begins with efficient removal of EG and water as condensates, but slows down considerably at IV>1.3 dl/g due to the restricted mobility of a part of the chain-ends due to ...

This study provides the molecular epidemiology data about the Rickettsia spp. infection associated with pet dogs in urban areas of Harbin city. Three rickettisae species pathogenic to humans were identified from pet dogs’ blood and the infested ticks in urban areas of Harbin city.

2011年6月1日 · Recently, there have been several recalls of commercial pet foods and treats in the United States because of contamination with Salmonella spp. This contamination creates a risk that pets ingesting these food items can become clinically ill or may become carriers of Salmonella organisms, but it is also a public health concern for pet owners who ...

2021年5月24日 · Cryptosporidium spp. are common protozoan pathogens in mammals. With pet rodents being integrated into modern life, the potential roles of them in transmitting parasites to humans need assessments. In the present study, we examined the occurrence of Cryptosporidium spp. in pet rodents …

2021年5月24日 · In the present study, we have examined the occurrence of Cryptosporidium spp. in 11 species of pet rodents in Guangdong, China, and determined their species and subtype identity through sequence analysis of the small subunit (SSU) rRNA and …
