Infection with the nontyphoidal Salmonella is a common cause of food-borne disease that leads to acute gastroenteritis/diarrhea. Severe/prolonged cases of Salmonella infection could also impact host nutritional status, but little is known about its effect on intestinal absorption of vitamins, including biotin. We examined the effect of Salmonella enterica serovar Typhimurium (S. typhimurium) in...
Sensitive and specific methodologies for detection of pathogenic gene at the point-of-care are still urgent demands in rapid diagnosis of infectious diseases. This work develops a simple and pragmatic electrochemical biosensing strategy for ultrasensitive and specific detection of pathogenic nucleic acids directly by integrating homogeneous target-initiated transcription amplification (HTITA) w...
A large number of poor prognosis neuroblastoma (NB) tumors constitutively express brain-derived neurotrophic factor (BDNF) and variably express the gene for its tyrosine kinase (Trk) receptor TrkB. Good prog nosis NB tumors typically express high levels of TrkA mRNA, which encodes the signal transducing receptor for nerve growth factor, pl40TrkA. These neurotrophins are necessary for neural cel...
Alkaline/neutral invertases (A/N-Inv), glucosidases that irreversibly hydrolyze sucrose into glucose and fructose, play significant roles in plant growth, development, and stress adaptation. They occur as multiple isoforms located in the cytosol or organelles. In Arabidopsis thaliana, two mitochondrial A/N-Inv genes (A/N-InvA and A/N-InvC) have already been investigated. In this study, we funct...
Multiple drug resistance in Salmonella is an emerging problem in the area of food safety. Depending on the virulence and antibiotic resistance characteristics of the Salmonella strain, infections of varying severity could result. In this study, a multiplex melt curve real-time PCR assay for the detection of virulent and antibiotic resistance strains of Salmonella was developed with two primer s...
The Suwannee River spans the Florida/Georgia border to the Gulf of Mexico, and contributes to regional irrigation and recreational activities. Association of Salmonella enterica with these resources may result in the contamination of produce and disease outbreaks. Therefore, surface water was examined for the distribution of S. enterica at multiple time points from 4 sites on the upper Suwannee...
Pancreatic cancer is a disease with essentially no effective treatment. To increase the potential for discovering effective treatment, we have devel oped a new treatment model whereby a human pancreatic cancer line, PANC-4, was orthotopically transplanted to the pancreas of nude mice as historically intact tumor tissue. The tumor grew with subsequent inva sive local tumor growth and liver and p...
امروزه بـرای شناسـایی و تشخیص سروتیپهای سالمونلا در نمونههای بالینی و مواد غذائی از روشهای سنتی تشخیص این باکتری استفاده مـیگـردد که وقتگیر و گاهی مشکلساز میباشند، اما با کشف روشهای سریع تشخیص مولکولی، این مشکلات تا حد زیادی مرتفع گردیده است. مطالعه حاضر، با هدف تشخیص سریع جدایههای مختلف سالمونلا بر اساس جسجوی ژن کروموزومی invA و نیز شناسائی جدایههای...
The Issue Invasive species, widely distributed across the western United States, pose critical conservation challenges on both non-Federal and Federal rangelands. Two of the biggest threats to ecosystem stability and integrity in the Great Basin (most of Nevada, a large part of Utah, and smaller sections of Oregon, Idaho, and California) are invasive annual grasses, particularly cheatgrass and ...
