Colorectal cancer mortality trends in the era of cancer survivorship in Korea: 2000-2020.

Purpose: Korea has implemented an early screening for colorectal cancer since 2004. However, it is not known whether this has translated into improved survival over the years.

Methods: We acquired colorectal cancer mortality data from the Cause of Death Statistics in Korea from 2000 to 2020.

How Many Alternatives Can Be Ranked? A Comparison of the Paired Comparison and Ranking Methods.

Objectives: To determine the feasibility of converting ranking data into paired comparison (PC) data and suggest the number of alternatives that can be ranked by comparing a PC and a ranking method.

Methods: Using a total of 222 health states, a household survey was conducted in a sample of 300 individuals from the general population. Each respondent performed a PC 15 times and a ranking method 6 times (two attempts of ranking three, four, and five health states, respectively).

Age- and cause-specific contributions to income difference in life expectancy at birth: findings from nationally representative data on one million South Koreans.

Background: Income is not frequently used to monitor health equity on a national level largely due to the lack of public data on income. Information on income allows policy makers to identify the economically disadvantaged population in a country directly. We examined differences in life expectancy (LE) at birth by income and quantified age- and cause-specific contributions to the LE differences using national health insurance data.

Functional analysis of six drought-inducible promoters in transgenic rice plants throughout all stages of plant growth.

There are few efficient promoters for use with stress-inducible gene expression in plants, and in particular for monocotyledonous crops. Here, we report the identification of six genes, Rab21, Wsi18, Lea3, Uge1, Dip1, and R1G1B that were induced by drought stress in rice microarray experiments. Gene promoters were linked to the gfp reporter and their activities were analyzed in transgenic rice plants throughout all stages of plant growth, from dry seeds to vegetative tissues to flowers, both before and after drought treatments.

Analysis of the Wsi18, a stress-inducible promoter that is active in the whole grain of transgenic rice.

There is currently a shortage of efficient promoters for stress-inducible gene expression, especially in monocotyledonous crops. Here, we report analysis of the rice Wsi18 promoter, a member of the group 3 Lea family, in transgenic rice plants. The abundance of Wsi18 mRNA increased in leaf tissues within 2 h of exposure to NaCl or abscisic acid (ABA) and within 6 h of exposure to drought, but there was no transcript increase in response to low-temperature conditions.

Analysis of five novel putative constitutive gene promoters in transgenic rice plants.

Novel constitutive gene promoters are essential components of crop biotechnology. Our analysis of five such promoters, APX, SCP1, PGD1, R1G1B, and EIF5, in transgenic rice plants is reported here. The five promoter regions were linked to the gfp reporter gene and transformed into rice.

Proteomics analysis of rice lesion mimic mutant (spl1) reveals tightly localized probenazole-induced protein (PBZ1) in cells undergoing programmed cell death.

Numerous reports have predicted/hypothesized a role for probenazole-induced protein (PBZ1) as a molecular marker in rice self-defense mechanism. However, the precise function of PBZ1 remains unknown. In the present study, we examined PBZ1 as a putative cell death marker in rice.
