WO kinds of mutations are known which affect bacterial sensitivity to Tstreptomycin: those conferring resistance to and others which confer dependence upon the antibiotic. Genetic analysis of such mutants from Escherichia coli has been confined to recombinational analysis by conjugation ( NEWCOMBE and NYHOLM 1950) and by transduction (HASHIMOTO 1960). By means of both types of tests, the existe...

Multiplex polymerase chain reaction (PCR) refers to the simultaneous amplification of multiple regions of deoxyribonucleic acid (DNA) using PCR. Commercial short tandem repeat (STR) assays that can coamplify as many as 16 different loci have become widely used in forensic DNA typing. This chapter will focus on some of the aspects of constructing robust STR multiplex assays, including careful de...

Human cytomegalovirus (HCMV) strains display genetic polymorphisms, and these polymorphisms can be analyzed to study viral transmission and pathogenesis. Recently, short tandem repeat (STR) length polymorphisms have been identified in the HCMV genome. We assessed the utility of STRs in characterizing HCMV strains and found that a multiplexed PCR assay using primers based upon these STRs accurat...

The present study compared the effects of full-field steady adapting backgrounds on the sensitivity of the scotopic threshold response (STR) of the dark-adapted ERG and scotopic PII (b-wave and d.c.-component) to Ganzfeld flashes in cats (n = 4), macaque monkeys (n = 2), and one human subject. In cats, the sensitivity of the STR was reduced by a factor of 2 by backgrounds that were 500 times we...

OBJECTIVE To investigate the relation between the degree of ST segment resolution (STR) after thrombolysis and the pressure derived collateral flow index (CFIp), determined using an intracoronary pressure measurement technique in patients with recent myocardial infarction. METHODS 33 patients were studied. TIMI grade III flow was achieved in the infarct related artery by thrombolysis. A surfa...

Joint involvement is a common manifestation in systemic lupus erythematosus (SLE). According to the SLE disease activity index 2000 (SLEDAI-2K), joint involvement is present in case of ≥2 joints with pain and signs of inflammation. However this definition could fail to catch all the various features of joint involvement. Alternatively the Swollen to Tender joint Ratio (STR) could be used. This ...
