amide gel electrophoresis (PAGE) on a 180× 160× 1.5-mm 10% polyacrylamide gel. The separated DNA strands were subsequently visualized by staining with either EtdBr or silver (2). Separation of the DNA strands before electrophoresis using streptavidin paramagnetic beads consistently yielded single-stranded products upon SSCP analysis (Figure 1). Treatment of DNA strands with S1 nuclease before S...

Escherichia coli was used to investigate quinolone resistance and mutations in gyrA gene of E. coli isolated from pet (dog and cat), human (pet's owner), vegetable and edible ice in Bangkok and vicinity. Susceptibility test for nalidixic acid (NA) showed similar percent resistance among the sample sources but a lower ciprofloxacin (CIP) resistance was found particularly in human source. Mutatio...

AI chatbots (AICs) have the potential to increase sustainability of a manufacturing supply chain (SC) through sales engagement and customer accomplish various activities related logistics SC in real time. Industry 4.0 (I4.0) has opened up several opportunities with internet-based technologies, along challenges for small medium enterprises (SMEs). SMEs are beginning adopt such technologies their...

Abstract The study investigates the relationship between information and communication-enabled supply chain integration (SCI) sustainable performance (SSCP). Moreover, to best of our knowledge, there is no empirical evidence on impact blockchain technologies (BT) SSCP. Therefore, primary aim this assess BT More specifically, was conducted examine direct influence SCI SSCP interactive effect Bas...

Aims-To develop a protocol that is applicable to single strand conformation polymorphism (SSCP), direct sequencing and loss of heterozygosity analysis of DNA.Methods-The protocol is based on the detection of biotinylated DNA by a Streptavidin-alkaline phosphatase conjugate. Biotinylation of DNA was achieved by using 5'-end biotinylated primers for PCR. After polyacrylamide gel electrophoresis, ...

The advent of the novel coronavirus, also called COVID-19, caused widespread disruptions worldwide. This unprecedented health crisis led to major in supply chain networks; therefore, innovative strategies and capabilities have potential alleviate its impacts. Considering this situation, study examined how COVID-19 impacted management innovation, information processing capability, business model...

PCR-restriction fragment length polymorphism (PCR-RFLP) and PCR-single-strand conformation polymorphism (PCR-SSCP) analyses were carried out on the 1.6-kb groEL gene from 41 strains of 10 different Salmonella serovars. Three HaeIII RFLP profiles were recognized, but no discrimination between the serovars could be achieved by this technique. However, PCR-SSCP analysis of the groEL genes of vario...

A novel mutation at codon 441 in exon 10 of the adenomatous polyposis coli (APC) gene was identified in a South African family of mixed ancestry, using a convenient, non-radioactive, heteroduplex-SSCP screening assay. This single thymidine deletion after nucleotide position 1322 creates a frameshift resulting in a downstream stop codon at amino acid residue 453 of the APC gene. Genotypes of nin...

Recent studies have shown that point mutations in the dihydropteroate synthase (DHPS) gene of human-derived Pneumocystis carinii are related to exposure to sulfa drugs and possibly represent the emergence of sulfa resistance. We developed a simple single-strand conformation polymorphism (SSCP) method to permit rapid detection of these mutations. With plasmid constructs, SSCP was able to detect ...
