Gene expression data from retina of Babl/c mouse under white LED light exposure

Project description:The widely used white light-emitting diodes (LED) deliver higher levels of blue light than do conventional domestic light sources. The high intensity of blue component is the main source of concern about the health risks of LED with respect to their light-toxicity to the retina. White LED light with higher correlated color temperature (CCT) is more likely to cause retinal injury in mice, significantly reducing the number of ONL nuclei, however apoptosis pathway may not be the only mechanism. We used the Affymetrix GeneChip (Mouse Genome 430 2.0) to describe the different influence on gene expression of mouse retina under white LED light with different CCT.

I-Scan Versus High-definition White Light

Project description:The purpose of the study is to assess whether the use of I-scan during colonoscopy leads to an increased yield of adenomas in the colon among a population at increased risk for CRC. Primary Outcome: To estimate the mean number of adenomas per colonoscopy for both high definition white light colonoscopy and I-scan enhanced colonoscopy Secondary Outcomes: 1. To estimate the recruitment rate 2. Number of adenomas detected in the right colon during the second look

Blue light inhibition of tuberization

Project description:A tuberization inhibitor has long been postulated, but not yet found. We found that blue light inhibits tuberization in Norland, a day-neutral variety of Solanum tuberosum L. Tissue-cultured plants formed tubers within 8 weeks under continuous darkness, and white, red, or far-red light. Preliminary experiments indicated that a one- or two-day exposure to blue light after 3-4 weeks of dark treatment will inhibit tuber formation in ‘Norland’ plants. Using this system and expression profiling, we may be able to identify candidate tuberization inhibitors. 'Norland' plants (subcultured from existing cultures and grown for two weeks under continuous 100 umol/m2-s white fluorescent light) were placed in tuber-inducing media containing 6% sucrose, vitamins, MS salts, and kinetin (2.5 mg/L). Tubes containing plants were wrapped in two layers of aluminum foil. After 3 weeks and 2 days, half of the tubes were exposed to 6-7 umol/m2-s blue light. The other half of the tubes were left in darkness (controls). After 2 days, all plants were harvested and frozen in liquid nitrogen. Plants exposed to blue light were harvested under blue light. Control plants were harvested under < 2 umol/m2-s light conditions. All plant transfers were done at 1700 (5 PM) to avoid possible complications due to circadian effects. Experiments were performed four times, from subculture to harvest. RNA was extracted from stem and leaf tissue of plants using the Qiagen RNeasy Plant Mini kit. Extracted RNA was then converted to dsDNA using the Invitrogen protocol and reagents for double stranded cDNA synthesis. The resulting dsDNA was in vitro transcribed into amplified RNA using the Ambion procedure and reagents for in vitro transcription. cDNA was purified using Qiagen MinElute columns and protocol. Amplified RNA was purified using Ambion columns or Qiagen RNeasy columns and the Ambion protocol, and quantified using RiboGreen dye fluorometry. Keywords: Direct comparison

I-Scan Vs High Definition White Light (Main Study)

Project description:The purpose of this study is to assess whether the use of I-Scan during colonoscopy leads to an increased yield of adenomas in the colon among a population at increased risk for CRC. Primary Outcome: Adenoma Detection Rate (ADR - No. of colonoscopies at which one or more histologically confirmed adenomas were found divided by the total no. of colonoscopies performed in the same time period) in the right colon using High Definition White Light Colonoscopy Versus I-Scan enhanced Colonoscopy. Secondary Outcomes: * Adenoma Detection Rate (ADR) of High Definition White Light Colonoscopy Versus I-Scan colonoscopy through out the entire colon. * Adenoma Detection Rate (ADR) in the right colon during the "Second look", irrespective of imaging modality. * Polyp Detection Rate (PDR - No. of colonoscopies at which one or more polyps were found(regardless of the histological type) divided by the total no. of colonoscopies performed in the Same time period) for each arm of the study in Right colon and throughout the entire colon. * Mean number of adenomas per procedure for each arm of the study in right colon and throughout the entire colon. * Mean number of polyps per procedure for each arm of the study in right colon and throughout the entire colon. * Number of neoplastic lesions for each arm of the study in the right colon and throughout the entire colon and number of neoplastic lesions missed on 1st pass of right colon. * Proportion of patients with diminutive lesions (< 5 mm) in each arm of the study * Proportion of patients with Flat lesions (height < 1/2 diameter) in each arm of the study * Proportion of patients with Sessile Serrated Adenoma in each arm of the study * Proportion of patients with invasive cancer in each arm of the study * Presence or absence of learning effect while using this technology given that use of I-Scan may train the human eye to better identify adenomas even without image enhancement.

Transcriptome analysis of Dunaliella salina on carotenoid biosynthesis under red and blue light induction

Project description:Light quality is an important abiotic factor that affects growth and development of photosynthetic organism. In this study, D. salina was exposed to red (660 nm) and blue light (450 nm), and cell growth, pigments, and transcriptome were analyzed. The RNA of D. salina was sequenced and transcriptomic response of algal cells after transitioning from white light to red and blue light was investigated. Genes encoding for enzymes involved in photosynthesis were down-regulated, whereas genes involved in the metabolism of carotenoid were up-regulated. Genes encoding for photoprotective enzymes related to reactive oxygen species scavenging were up-regulated under both red and blue light. The present transcriptomic study would assist in the comprehensive understanding of carotenoid biosynthesis of D. salina.
