The genetic control of IgA activity against Teladorsagia circumcincta and its association with parasite resistance in naturally infected sheep
(2002-05)Previous studies in deliberately infected sheep have shown an association between IgA activity against 4th-stage larvae of Teladorsagia circumcincta and parasite growth, development and fecundity. The purpose of this ... -
Genetic differentiation between and within strains of the saw-toothed grain beetle, Oryzaephilus surinamensis (Coleoptera Silvanidae) at RAPD loci
(1997-08)Nine strains of Oryzaephilus surinamensis have been kept in laboratory culture for periods ranging from 5 to 30 years (30-180 generations). Two RAPD primers provided sufficient information to separate the strains reliably ... -
Genetic diversity of Fusarium fujikuroi isolated from bakanae disease of rice on the basis of vegetative compatibility
(2008)Fusarium fujikuroi which was originally studied in Japan is a pathogen of bakanae disease of rice. The disease was recorded in almost all countries where rice is grown commercially, including Malaysia and Indonesia. A total ... -
Genetic Diversity of Mycobacterium tuberculosis Complex Strains Isolated from Patients with Pulmonary Tuberculosis in Anambra State, Nigeria
(2017-02-08)In this study, we analyzed Mycobacterium tuberculosis complex (MTC) genetic diversity in Anambra State, Nigeria based on spoligotyping followed by 5-loci exact tandem repeats (ETRs). Spoligotyping of 180 MTC strains isolated ... -
Genetic Factors That Could Affect Concussion Risk in Elite Rugby
(2021-01-22)Elite rugby league and union have some of the highest reported rates of concussion (mild traumatic brain injury) in professional sport due in part to their full-contact high-velocity collision-based nature. Currently, ... -
Genetic local search for multicast routing with pre-processing by logarithmic simulated annealing
(2008)Over the past few years, several local search algorithms have been proposed for various problems related to multicast routing in the off-line mode. We describe a population-based search algorithm for cost minimisation of ... -
Genetic modification and food : the policy challenges
(1999-03)Paper presented at the annual Public Health Forum 1999 -
Genetic modification and the environment : EC directives and the genesis of UK regulation
(1993-08)The rapid advances in bio-technology that have been witnessed in recent years have been matched by an increase in concern associated with both the moral dimensions and the possible environmental impacts of genetically ... -
Genetic modifiers ameliorate endocytic and neuromuscular defects in a model of spinal muscular atrophy
(2020-09-16)Background: Understanding the genetic modifiers of neurodegenerative diseases can provide insight into the mechanisms underlying these disorders. Here, we examine the relationship between the motor neuron disease spinal ... -
Genetic parameters for faecal egg count following mixed, natural, predominantly Ostertagia circumcinta infection and relationships with live weight in young lambs
(1996-12)Faecal egg counts and live weights were measured on approximately 200 predominantly twin-born Scottish Blackface lambs each year for 3 years, from 2 to 6 months of age. Measurements were made at 4-week intervals following ... -
Genetic Programming for Developing Simple Cognitive Models
(Cognitive Science Society, 2023-07-29)Frequently in psychology, simple tasks that are designed to tap a particular feature of cognition are used without considering the other mechanisms that might be at play. For example, the delayed-match-to-sample (DMTS) ... -
A genetic programming-based convolutional deep learning algorithm for identifying COVID-19 cases via X-ray images
(2023-08-31)Evolutionary algorithms have been successfully employed to find the best structure for many learning algorithms including neural networks. Due to their flexibility and promising results, Convolutional Neural Networks (CNNs) ... -
Genetic regulatory network models of biological clocks : evolutionary history matters
(2008)We study the evolvability and dynamics of artificial genetic regulatory networks (GRNs), as active control systems, realizing simple models of biological clocks that have evolved to respond to periodic environmental stimuli ... -
Genetic variation for secondary seed dormancy and seed longevity in a set of black-seeded European winter oilseed rape cultivars.
(2013-04)Secondary seed dormancy in oilseed rape is a phenomenon that allows seeds to survive in the soil for many years without germination. Following soil cultivation, dormant seeds may germinate in subsequent years, and they are ... -
Genetic variation in target-site resistance to pyrethroids and pirimicarb in Tunisian populations of the peach-potato aphid, Myzus persicae (sulzer) (Hemiptera: Aphididae)
(2016-10-27)BACKGROUND We used molecular assays to diagnose resistance to pyrethroids and pirimicarb in samples of Myzus persicae from field crops or an insect suction trap in Tunisia. Genotypes for resistance loci were related to ... -
Genome expansion of Arabis alpina linked with retrotransposition and reduced symmetric DNA methylation
(2015-02-02)Despite evolutionary conserved mechanisms to silence transposable element activity, there are drastic differences in the abundance of transposable elements even among closely related plant species. We conducted a de novo ... -
Genome-wide screen for oxalate-sensitive mutants of Saccharomyces cerevisiae
(2007-09)Oxalic acid is an important virulence factor produced by phytopathogenic filamentous fungi. In order to discover yeast genes whose orthologs in the pathogen may confer self-tolerance and whose plant orthologs may protect ... -
Genomic evidence for genes encoding leucine-rich repeat receptors linked to resistance against the eukaryotic extra- and intracellular Brassica napus pathogens Leptosphaeria maculans and Plasmodiophora brassicae
(2018-06-01)Genes coding for nucleotide-binding leucine-rich repeat (LRR) receptors (NLRs) control resistance against intracellular (cell-penetrating) pathogens. However, evidence for a role of genes coding for proteins with LRR domains ...
