Ghrelin antagonist regulates metabolic hormone receptorsin the hypothalamus of ewes
(Elsevier, 2020-04)
This study evaluates the effects of ghrelin antagonist on mRNA abundance for metabolic hormone receptors in feed-restricted ewes. Ewes were randomly assigned to one of three treatments; Control (CO): feed above maintenance ...
Isolation, identification and selection of antagonistic yeast against Alternaria alternata infection and tenuazonic acid production in wine grapes from Argentina
(Elsevier Science, 2018-02)
Epiphytic isolates with yeast characteristics from grapes of the Malbec cultivar were obtained in order to find antagonists against Alternaria alternata. From a total of 111 isolates, 82% corresponded to the yeast-like ...
Trichoderma as biological control agent: Scope and prospects to improve efficacy
(Springer, 2021-05)
A major current challenge is to increase the food production while preserving natural resources. Agricultural practices that enhance the productivity and progressively improve the soil quality are relevant to face this ...
Studies on possible modes of action and tolerance to environmental stress conditions of different biocontrol agents of foliar diseases in maize
(Scientific Research Publishing, 2020-06)
The present study evaluates the possible modes of action of antagonistic bacteria and their tolerance to UV radiation, temperature and osmotic stress. The partial 16S-23S rRNA gene sequencing of eight antagonistic bacteria ...
Enhancing the efficacy of yeast biocontrol agents against postharvest pathogens through nutrient profiling and the use of other additives
(Academic Press Inc Elsevier Science, 2018-06)
Vishniacozyma victoriae and Pichia membranifaciens were selected in a previous work for their biocontrol effectiveness against Penicillium expansum and Botrytis cinerea, the causal agents of blue and grey mold of pear ...
Potential Bacterial Antagonists for the Control of Charcoal Rot (Macrophomina phaseolina) in Strawberry
(MDPI, 2021-11)
The effect of antagonistic bacteria to control Macrophomina phaseolina was evaluated under in vitro, growth chamber, greenhouse and field conditions. A total of 177 bacteria, isolated from Athrocaulon macrostachyum rhizosphere ...
Effects of angiotensin type 1 receptor antagonists on Parkinson's disease progression: an exploratory study in the PPMI database
(Elsevier, 2021-05)
Introduction: We explored the potential clinical effects of angiotensin-II AT1 receptor blockers (ARBs) and angiotensin-converting enzyme inhibitors (ACEIs) in patients from the Parkinson's Progress Marker Initiative (PPMI) ...
Angiotensin-(1-7) reduces norepinephrine release through a nitric oxide mechanism in rat hypothalamus
(Lippincott Williams, 2000-06)
Angiotensin (Ang)-(1-7) elicits a facilitatory presynaptic effect on peripheral noradrenergic neurotransmission, and because biological responses to the heptapeptide on occasion are tissue specific, the present investigation ...
In vitro effects of both dopaminergic and enkephalinergic antagonists on the ovarian growth of Cherax quadricarinatus (Decapoda, Parastacidae), at different periods of the reproductive cycle
(Elsevier Science Inc, 2011-01)
The in vitro effect of both spiperone (dopaminergic antagonist) and naloxone (enkephalinergic antagonist), was assayed on small pieces of ovary dissected from C. quadricarinatus females, with the eventual addition of some ...
A novel dihydro-pyrazolo(3,4d)(1,2,4)triazolo(1,5a)pyrimidin-4-one (AJ23) is an antagonist at adenosine A1 receptors and enhances consolidation of step-down avoidance
(Elsevier Science, 2012-10)
Adenosine A1 receptor antagonists are of potential value in the treatment of cognitive dysfunction. We have developed compound AJ23 (7-methyl-1-phenyl-1,8-dihydro-pyrazolo-(3,4d)(1,2,4)-triazolo(1,5a)-pyrimidin-4-one) as ...
