Comparative physiology of radish populations with differential sensitivity to O₃ and SO₂
… more than either plants selected for sensitivity to O₃ (O₃S) or NS plants when exposed to either O₃ or SO₂. The hypocotyl was most affected by pollutant exposure, leading to reduced root/shoot ratios. Plants selected for resistance or sensitivity to SO₂ generally had biomass production …

The Role of Differential Sensitivity to Retinoic Acid (RA) in Regulating Spermatogonial Fate
In the mammalian testis, the foundation of spermatogenesis is provided by spermatogonial stem cells (SSCs); their progeny either remain as stem cells (following a self-renewal division) or proliferate as undifferentiated progenitors prior to differentiating in response to retinoic acid (RA) and …

The relationship between p53 mutations and differential sensitivity to anti-cancer drugs in oesophageal cancer cell lines
… South African oesophageal cancer cell lines, sensitivity to anti-cancer drugs, presence of P-glycoprotein (P-gp) and glutathione-S-transferase (GST), and p53 mutations were investigated. Chemosensitivity of the WHCO1, WHC03 and HCu-13 cell lines to 7 anti-cancer agents was determined. WHC03 …

Dual Receptor Uptake of Low-Density Lipoprotein Docosahexaenoic Acid (LDL-DHA) Elicits Differential Sensitivity Across Breast Cancer Subtypes
We proposed to treat breast cancer with a novel nanomedicine previously shown to be effective in the treatment of primary liver tumors in rats. This nanoparticle is comprised of the low-density lipoprotein which acts as a carrier for the omega-3 fatty acid docosahexaenoic acid (DHA). The LDL-DHA …

Differential Sensitivity of Intraindividual Variability Dispersion and Global Cognition in the Prediction of Functional Outcomes and Premature Mortality in Precariously Housed and Homeless Adults
Precariously housed and homeless individuals are exposed to adverse factors negatively impacting neurocognitive functioning. Intraindividual variability (IIV) across neuropsychological tests (i.e., IIV dispersion) has been used as a marker of frontal system pathology. Increased IIV dispersion has …

Responses of gas exchange and the antioxidant system of soybean cultivars to ozone and/or sulfur dioxide
… Merr.), "Dare", "Williams" and "Essex", with differential sensitivity to ozone (O₃) based on visible injury were exposed once to 0.20 µl⁻¹ O₃ and/or 0.70 µl 1⁻¹ sulfur dioxide (SO₂) for 4 hr. The cv Dare was considered sensitive, cv Williams intermediate and cv Essex tolerant to O₃. Cultivars …

Detection of video frame insertion based on constraint of human visual perception
… The main idea is based on the so-called differential sensitivity. That is, that the variation of brightness of neighboring video frames has some constraint. First, the video sequence is partitioned into short and overlapping sub-sequences. Second, the ratio of the temporal variation of …

PHF6 modulates the chromatin landscape in B-cell leukemia
… tolerance of aberrant oncogenic signaling, and differential sensitivity to frontline and targeted therapies. These findings suggest that active maintenance of a precise chromatin landscape is essential for sustaining proper leukemia cell identity, and that loss of a single factor (PHF6) can …

The Role of Low Tone Average in the Diagnosis of Meniere's Disease
… promise that needs further evaluation regarding differential sensitivity given specific patient characteristics.

Application of High-Performance Liquid-Chromatography Mass-Spectrometry Platform to Study Metabolism and Epigenetic Control of Metabolism
… global changes in metabolism, as well as differential sensitivity towards glycolytic and mitochondrial inhibitors.</p>

An Electrophysiological Study of Noisy Channel Sentence Comprehension.
… would be held true if, comprehenders show differential sensitivity to different error types. Behavioural and ERP data from our study revealed the same. The brain responded with a sustained negativity (anterior) at head-noun position for deletion errors, while insertion errors elicited a …

Spectrum and conversion efficiency measurements of suprathermal electrons from relativistic laser plasma interactions
… a filter stack Bremsstrahlung spectrometer with differential sensitivity up to 500 keV. The spectrometer is used with a single photon counting camera for measuring K[alpha] emission in experiments on the Titan laser (1.06 [mu]m, 150 J, 0.7 ps) at Lawrence Livermore National Laboratories. The …

Comparative analysis of cytotoxic necrotizing factor (CNF) toxins: Compatibility of cargo with delivery vehicle and identification of amino acid residues that modulate pH-dependent cytosolic cargo delivery
… investigated whether the previously reported differential sensitivity of the CNF toxins to endosomal acidification impacts their cargo delivery efficiency. We found that replacing particular acidic amino acid residues from the putative insertion-trigger motif of the CNFy translocation domain …

Effects of Chronic Oxidative Stress on TRPM2 and TRPC3 Channels: Potential Implications for Bipolar Disorder
… greater susceptibility to cell death and a differential sensitivity of TRPM2-mediated calcium influx to acute oxidative stress compared with healthy subjects, further supporting reduced cellular resilience in the pathophysiology of BD-I. I also demonstrated that TRPC3 protein is expressed in …

Combination therapy studies with the vascular disruptive agent combretastatin-a4-phosphate (CA4P)
… whether the angiogenic profile can explain differential sensitivity of human tumours to CA4P. We found no strong relationships between DCE-MRI variable change following CA4P and the angiogenic markers.

The Analysis of the MCF7 Cancer Model System and the Effects of 5-AZA-2'-Deoxycytidine Treatment on the Chromantin State Using a Novel Microarray-Based Technology for High Resolution Global Chromatin State Measurement
… indicate that certain gene regions exhibit differential sensitivity to 5 Aza dC treatment, and therefore may be regulated independently. Using functional annotation, expression microarray, and comparative genomic hybridization data, this work should provide a framework through which the …

The Brains of Babies: A Surface Based Approach To Study Cortical Development in Term and Preterm Human Infants
