Cyclic lipopeptide-producing Pseudomonas koreensis group strains dominate the cocoyam rhizosphere of a Pythium root rot suppressive soil contrasting with P. putida prominence in conducive soils
(Wiley, 2020)Pseudomonas isolates from tropical environments have been underexplored and may form an untapped reservoir of interesting secondary metabolites. In this study, we compared Pseudomonas and cyclic lipopeptide (CLP) diversity ... -
Cyclic pairs and common best proximity points in uniformly convex Banach spaces
(De Gruyter, 2017)In this article, we survey the existence, uniqueness and convergence of a common best proximity point for a cyclic pair of mappings, which is equivalent to study of a solution for a nonlinear programming problem in the ... -
Cycling-specific isometric resistance training improves peak power output in elite sprint cyclists
(Wiley, 2020)Introduction This study aimed to assess the efficacy of a 6‐week cycling‐specific, isometric resistance training program on peak power output (PPO) in elite cyclists. Methods Twenty‐four elite track sprint cyclists ... -
Cyclometallated platinum(II) complexes of benzylidene-2,6-di-isopropylphenylamine containing bidentate phosphines: synthesis, structural properties and reactivity studies
(RSC, 2015)The reaction of the cyclometallated complex [PtCl(N^C)(dmso)], 1 (N^C represents the cyclometallated Schiff base, benzylidene-2,6-diisopropylphenylamine), with 1,1’-bis(diphenylphosphino)ferrocene, dppf, bis(diphenylph ... -

Cymothoa hermani sp. nov. (Isopoda, Cymothoidae, Crustacea), a parasitic isopod, collected off the Zanzibar coast, Tanzania from the mouth of a parrotfish (Scaridae)
(Magnolia Press, 2011)Cymothoa hermani sp. nov., a buccal fish-parasitic isopod is described from off Unguja Island, Zanzibar, from the buccal cavity of the marbled parrotfish, Leptoscarus vaigiensis. Cymothoa hermani sp. nov. is characterised ... -
Cytochrome c oxidase I and cytochrome b gene sequences indicate low genetic diversity in South African Busseola fusca (Lepidoptera: Noctuidae) from maize: short communications
(ESSA, 2016)The African maize stem borer, Busseola fusca, feeds on a limited number of host plant species (Calatayud et al. 2014), which include crops such as maize, pearl millet and sorghum. This pest occurs throughout sub-Saharan ... -
Cytochrome c Oxidase sequences of Zambian wildlife helps to identify species of origin of meat
(Hindawi Publishing Corporation, 2016)Accurate species identification is a crucial tool in wildlife conservation. Enforcement of antipoaching law is more achievable with robust molecular identification of poached meat. Determining the region where the animal ... -
Cytochrome P450-mediated warfarin metabolic ability is not a critical determinant of warfarin sensitivity in avian species: in vitro assays in several birds and in vivo assays in chicken
(Wiley, 2015)Coumarin-derivative anticoagulant rodenticides used for rodent control are posing a serious risk to wild bird populations. For warfarin, a classic coumarin derivative, chickens have a high median lethal dose (LD50), whereas ... -
Cytotoxic effects of polystyrene–titanium–arsenate composite in cultured H9c2 cardiomyoblasts
(Springer Verlag, 2013)In the present report, we explored the toxicological behaviour of engineered polystyrene–titanium– arsenate (PS–Ti–As) composite using cultured H9c2 cardiomyoblasts in vitro. From in vitro cytotoxicity studies, it appears ... -
Cytotoxicity, phytochemical, antiparasitic screening, and antioxidant activities of mucuna pruriens (Fabaceae)
(MDPI, 2020)This study aimed at assessing the biological activities of Mucuna pruriens seeds using cytotoxicity, phytochemical, antiparasitic screening, and antioxidant assays. Mature fruits of M. pruriens were harvested from Fort ... -
Dactylogyrids (Platyhelminthes: Monogenea) from Sudanese Labeo spp., with a description of Dogielius sennarensis n. sp. and a redescription of Dogielius fl osculus Guégan, Lambert & Euzet, 1989
(Institute of Parasitology, 2018)Dactylogyrid monogeneans of Labeo horie Heckel, 1847 and L. niloticus (Linnaeus, 1758) (Cyprinidae) were surveyed at two sites on the River Nile in Sudan. The present study reports the presence of ten species of Dactylogyrus ... -
Dactylogyrus spp. (Monogenea, Dactylogyridae) from the Gills of Enteromius spp. (Cypriniformes, Cyprinidae) from the Limpopo Province, South Africa with descriptions of three new species
(Springer, 2020)Background Monogenean parasites of the genus Dactylogyrus Diesing, 1850 parasitize mostly gills of cyprinoids hosts. Of 100 species currently known from African continent, approximately 35 have been described from Enteromius ... -
Damring formation during rotary kiln chromite pre-reduction: effects of pulverized carbonaceous fuel selection and partial pellet melting
(Springer, 2018)Electricity consumption is the largest cost contributing factor in the production of ferrochrome. Currently the pelletized chromite pre-reduction process (solid-state reduction of chromite) is the process option with the ... -
Darboux transformation and solitons for an integrable nonautonomous nonlinear integro-differential Schrödinger equation
(World Scientific, 2017)By modifying the scheme for an isospectral problem, the non-isospectral Ablowitz-Kaup-Newell-Segur (AKNS) hierarchy is constructed via allowing the time varying spectrum. In this paper, we consider an integrable nonautonomous ... -
Data on the optimisation of a solid phase extraction method for fractionating estrogen metabolites from small urine volumes
(Elsevier, 2020)Certain estrogen metabolites have been implicated in the pathophysiology of breast cancer. Moreover, the estrogen metabolite profiles of healthy women and those with (a high risk of) breast cancer differ significantly. The ... -
Data transformations and goodness-of-fit tests for type-II right censored samples
(Springer, 2015)We suggest several goodness-of-fit (GOF) methods which are appropriate with Type-II right censored data. Our strategy is to transform the original observations from a censored sample into an approximately i.i.d. sample ... -
