Frailty modeling of bimodal age-incidence curves of nasopharyngeal carcinoma in low-risk populations
The incidence of nasopharyngeal carcinoma (NPC) varies widely according to age at diagnosis, geographic location, and ethnic background. On a global scale, NPC incidence is common among specific populations primarily living in southern and eastern Asia and northern Africa, but in most areas, including almost all western countries, it remains a relatively uncommon malignancy. Specific to these l...
The important role of non coding RNAs (ncRNAs) in the cell has made their identification a critical issue in the biological research. However, traditional approaches such as PT-PCR and Northern Blot are costly. With recent progress in bioinformatics and computational prediction technology, the discovery of ncRNAs has become realistically possible. This paper aims to introduce major computationa...
The article describes in detail methodical procedures for isolation of small RNA molecules, their electrophoresis, northern blotting and finally detection by hybridization with radioactively labeled riboprobes. The presented protocols were successfully introduced and used in our laboratory.
Fish mercury levels appear to be increasing in Ontario, Canada, which covers a wide geographical area and contains about 250 000 lakes including a share of the North American Great Lakes. Here we project 2050 mercury levels in Ontario fish, using the recently measured levels and rates of changes observed during the last 15 years, and present potential implications for fish and human health. Per...
We introduce here an alternative to conventional northern blotting that requires only minute amounts of RNA. This has been achieved by modification of methods currently used for the mapping of mRNA 5'-terminal ends. The terminal desoxynucleotidyl transferase-mediated G-tailing, cap finder, ligation-anchored and RNA ligase-mediated approaches followed by polymerase chain reaction protocols all p...
A panel of 164 continuous human leukemia-lymphoma cell lines was analyzed for expression of c-kit using Northern blotting and reverse transcriptase-polymerase chain reaction (RT-PCR). The c-kit transcripts were detectable in cell lines assigned to the myeloid (in 7 of 29 by Northern blotting and in 4 of 8 by RT-PCR), monocytic (in 1 of 24 by Northern blotting and in 3 of 6 by RT-PCR), erythroid...
BACKGROUND Globally, trachoma is the leading cause of infectious blindness and Australia is the only developed country with endemic trachoma. It is found in remote Indigenous communities burdened with poverty, overcrowding and poor hygiene. Lack of culturally appropriate health promotion, a small trachoma workforce and lack of awareness and support for trachoma elimination in general, were earl...
The pH-regulated expression of the acid (AXP) and alkaline (AEP) extracellular proteases of the yeast Yarrowia lipolytica 148 was analysed. Expression in batch and continuous cultures was determined at the mRNA level by Northern blotting, and at the enzyme level by enzyme assays and Western blotting. Culture pH regulated AEP and AXP expression predominantly at the level of mRNA content. Highest...
A rapid and easy procedure for preparing Northern blots is described. RNA is denatured with glyoxal in the presence of ethidium bromide and glycerol, then electrophoresed through agarose in a buffer that does not require recirculation. Without any additional washes, the RNA is vacuum-blotted to a nylon membrane in NaOH, which simultaneously removes the glyoxal adducts. All of these steps plus p...
