Functional genomics of the horn fly, Haematobia irritans (Linnaeus, 1758)
(BioMed Central, 2011-02-10)
Background: The horn fly, Haematobia irritans (Linnaeus, 1758) (Diptera: Muscidae) is one of the most important ectoparasites of pastured cattle. Horn flies infestations reduce cattle weight gain and milk production. ...
Poincare homology sphere, lens space surgeries, and some knots with tunnel number two
(2015-04-25)
We exhibit an infinite family of knots in the Poincare homology sphere with tunnel number 2 that have a lens space surgery. Notably, these knots are not doubly primitive and provide counterexamples to a few conjectures. ...
Importance of the long-chain fatty acid beta-hydroxylating cytochrome P450 enzyme YbdT for lipopeptide biosynthesis in Bacillus subtilis strain OKB105
(MDPI, 2011-03-08)
Bacillus species produce extracellular, surface-active lipopeptides such as surfactin that have wide applications in industry and medicine. The steps involved in the synthesis of 3-hydroxyacyl-coenzyme A (CoA) substrates ...
PPE surface proteins are required for heme utilization by Mycobacterium tuberculosis
(American Society for Microbiology, 2017-03-08)
Iron is essential for replication of Mycobacterium tuberculosis, but iron is efficiently sequestered in the human host during infection. Heme constitutes the largest iron reservoir in the human body and is utilized by many ...
Coxiella burnetii employs the Dot/Icm type IV secretion system to modulate host NF-KB/RelA activation
(Frontiers Media, 2016-12-19)
Coxiella burnetii is the causative agent of Q fever and an obligate intracellular pathogen in nature that survives and grows in a parasitophorous vacuole (PV) within eukaryotic host cells. C. burnetii promotes intracellular ...
Factors associated with nutritional status of infants and young children in Somali Region, Ethiopia: a cross- sectional study
(BioMed Central, 2015-09-02)
Background: Inadequate nutrition during the first two years of life may lead to childhood morbidity and mortality, as well as inadequate brain development. Infants are at increased risk of malnutrition by six months, when ...
Mental and substance use disorders from early adolescence to young adulthood among indigenous young people: Final diagnostic results from an 8-year panel study
(Springer Science and Business Media LLC, 2014)
Objective: Our objective was to investigate change in prevalence rates for mental and substance abuse disorders between early adolescence and young adulthood in a cohort of indigenous adolescents who participated in an ...
CELLULASE6 and MANNANASE7 affect cell differentiation and silique dehiscence in Arabidopsis
(2017-06-19)
Cellulases, hemicellulases and pectinases play important roles in fruit development and maturation, but mutants with defects in the fruit have not been reported for cellulase or hemicellulase genes. Here we report the ...
Proteomics approach to the study of cattle tick adaptation to white tailed deer
(Hindawi Publishing Corporation, 2013)
Cattle ticks, Rhipicephalus (Boophilus) microplus, are a serious threat to animal health and production. Some ticks feed on a single host species while others such as R. microplus infest multiple hosts. White tailed deer ...
Influence of olfactory and visual cover on nest site selection and nest success for grassland-nesting birds
(Wiley Open Access, 2017-07-03)
Habitat selection by animals is influenced by and mitigates the effects of predation and environmental extremes. For birds, nest site selection is crucial to offspring production because nests are exposed to extreme weather ...
