Reduction of adaptive genetic diversity radically alters eco‐evolutionary community dynamics
Ecology Letters, 2010Ecology Letters (2010) 13: 989–997 Abstract Adaptive variation in the traits determining ecological interactions can lead to evolution so rapid that ecological dynamics

As someone located in Daoist Studies and Religious Studies without formal theological training, I have developed my own pedagogical approach to teaching Comparative Theology and the theologies of religious diversity. I begin with a discussion of the relative appropriateness and problematic nature of the terms “Theology” and “Comparative Theology” for ...

Starvation-Related Alterations in Free Radical Tissue Defense Mechanisms in Rats
Diabetes, 1987Alterations in endogenous free radical-scavenging defense mechanisms of rat tissues after body weight loss (induced by starvation for 72 h) associated with hypoinsulinemia were investigated. The activities of catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase (GSH-PX), and glutathione (GSSG) reductase as well as levels of reduced ...

Sequencing of Helicobacter pylori will radically alter research
BMJ, 1997Publication of the complete genome sequence of the gut pathogen Helicobacter pylori will radically change research approaches and pave the way for completely new methods of treatment, say molecular experts. Scientists from the Institute for Genome Research in Rockville, Maryland, United States, have described how H pylori has a circular genome ...

Alteration of free radical development by ophthalmic viscosurgical devices in phacoemulsification
Journal of Cataract and Refractive Surgery, 2006To determine the effect of ophthalmic viscosurgical devices (OVDs) and irrigation/aspiration (I/A) settings on free radical development during phacoemulsification.Department of Ophthalmology, Nippon Medical School, Tokyo, Japan.Free radicals were detected by the electron spin resonance (ESR) spin-trap method. After a spin-trapping agent, 5,5-dimethyl-1-

Alterations in free radical scavenging mechanisms following blood-brain barrier disruption
Free Radical Biology and Medicine, 1993It has been reported earlier that rat microvessels which constitute the blood-brain barrier (BBB) are rich in free radical scavenging enzymes. In the present investigation, BBB of rat was disrupted by intravenous infusion of the hypertonic saline and changes in enzymes--namely, superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx ...

Covalent Cross-Links in Oxygen Free Radical Altered Human Immunoglobulin G
Scandinavian Journal of Rheumatology, 1988The damaging effect of an oxygen free radical generating system, i.e. ultraviolet irradiation, on human immunoglobulin G (IgG) was studied. The free radical altered IgG was analysed by a high performance liquid chromatograph equipped with a TSK G 3000 SW-column.

Radical alterations in the roles of homeobox genes during echinoderm evolution
Nature, 1997Echinoderms possess one of the most highly derived body architectures of all metazoan phyla, with radial symmetry, a calcitic endoskeleton, and a water vascular system. How these dramatic morphological changes evolved has been the subject of extensive speculation and debate, but remains unresolved.

Can Radical Prostatectomy Alter the Progression of Poorly Differentiated Prostate Cancer?
Journal of Urology, 1994A favorable outcome after radical prostatectomy for early stage prostate cancer has sometimes been attributed to the relatively benign natural history of the disease rather than the beneficial effects of treatment. Poorly differentiated tumors, however, are recognized as inherently aggressive and progress rapidly when managed conservatively.

Polymer, 2017
Abstract Atom transfer radical coupling (ATRC) reactions assisted by radical traps were studied under various conditions, with the extent of coupling of polymer chains monitored as a function of time. When using a radical trap that tended to aggregate into dimers, such as 2-methyl-2-nitrosopropane (MNP), the rate of coupling was enhanced when ...
