Abstract:

SummaryThe fertilisation of free-spawning invertebrates, mainly sea urchins, has been studied extensively during the last hundred years. However, results obtained fromin vitroexperiments do not always reflect what happens in the real world. Organisms in their natural habitats have a complex set of challenges, cues and behaviours to contend with during fertilisation and early development, factors that are normally not considered in the laboratory setting. This review examines recent work on fertilisation ecology and discusses the relevance of these results to the findings gleaned from laborator

The highest marketable yield, dry matter yield and nitrogen uptake were obtained at the highest nitrogen fertilisation rate when in combination with sulphur.

Abstract:

SUMMARYFruit and vegetable farming generally involves high levels of chemical inputs despite the fact that consumers are increasingly concerned about the sanitary and organoleptic aspects of fruit quality. Pineapple is largely subject to these issues since it is dominated by conventional monocropping with high levels of agrochemical inputs due to nitrogen (N) and potassium (K) fertilisation, weed management, crop protection and flowering induction. However, low-input pineapple cropping systems are both rare and little documented. Our study aimed at replacing all or part of the chemical fertili

Abstract:

Background: ICSI typically results in fertilisation rates of >65% however patients may still have low or no fertilisation despite the oocyte and sperm quality appearing normal. After entry of the sperm into the oocyte, a cascade of reactions facilitates calcium release and subsequent oocyte activation. In cases of poor or failed fertilisation it is possible that this cascade fails and therefore different methods of artificial oocyte activation are used to try and induce calcium release. Aim: To determine if calcium chloride dihydrate supplementation in the PVP (5mM) at the time of ICSI (ICS

Polyspermic fertilisation has been a continual problem in porcine in vitro fertilisation. Over the years, researchers have tried to resolve this persistent problem, but have not been entirely successful in their endeavour. This can be attributed to several factors.

SummaryDuring fertilisation in starfish oocytes, the fertilisation cone develops temporarily beneath the penetrating sperm. The role of the fertilisation cone in sperm incorporation in the starfish Asterias amurensis was examined using cytochalasin B (CB). CB (2 μM) allowed sperm acrosomal process–egg plasma membrane fusion and egg activation, but inhibited the development of the fertilisation cone containing actin microfilaments. When sperm were added to intact oocytes (with the jelly coat and vitelline coat) in seawater containing CB, the sperm head did not penetrate the fertilisation membra

In this article the available information on the effects of host plant’s nitrogen fertilisation on the preference/performance of the sap-sucking insects (Hemiptera) and on host plants tolerance is reviewed. There is a very strong general tendency that nitrogen fertilisation increases the preference/performance of the sap sucking insects. Important exceptions are known, when the excessive nitrogen fertilisation decreases the preference/performance of the hemipteran herbivores. Host plant tolerance usually improves with nitrogen fertilisation: exceptions are known when the herbivore is very effi

Abstract:

Fertilisation in ascidian oocytes triggers a plasma membrane current, the release of intracellular calcium and the degradation of Maturation Promoting Factor (MPF) activity leading to the completion of meiosis and the initiation of embryo development. We have previously shown that the fertilisation current in ascidians is produced through the metabolism of nicotinamide nucleotide (NN) metabolites to ADP ribose. In this study we have used nicotinamide to test whether NN metabolism plays additional roles in fertilisation in ascidians. Nicotinamide treatment blocked calcium-induced calcium releas

Abstract:

The role of calmodulin in fertilisation events was examined in a zona-free mouse system by using a selective calmodulin inhibitor, calmidazolium (1 μM). The effects of this antagonist were studied either on the ooplasmic calcium oscillations induced by fertilisation by using the Ca2+ indicator, fluo-3/AM, or on pronucleus formation 4 h later by using the nucleic acid stain, Syto-15. When the calmidazolium treatment was applied to one or the other gamete before insemination, the fertilisation process was affected only when spermatozoa were treated: most of the oocytes were partially fertilised

Abstract:

The effect of S (60, 120 and 240 kg ha−1) and N (45 and 90 kg ha−1) fertilization on the yield and quality of soybean (Glycine max L. Merrill ’Maple Amber’), grown on a Kamouraska silty clay loam, was studied under greenhouse conditions, and in the field over a period of 2 yr. In the greenhouse, soybean (dry matter and pod weights) was responsive to N and S, and an excess of sulfate reduced P and K levels in the upper leaves. In the field, small or nonsignificant differences between fertilizer treatments were found for yield parameters in 1988 and 1989. However, as compared to the 45-kg ha−1 a

Abstract:

The case for making healthcare more sustainable is becoming increasingly urgent. Medical professionals understand the need to reduce the cost and environmental impact of our work. We also see that being creative in how we plan treatment pathways and communicate with patients can allow us to work sustainably in terms of the resources required, and in tandem, deliver real benefits for patients. Approaches that deliver ‘prevention rather than cure’ and keep medical intervention as minimally invasive as possible are often better for patients, as well as better for the environment. These concepts a

Abstract:

This study aimed to compare bacterial community structure differences in yellow paddy soil under long-term chemical/organic fertilisation and fertiliser conversion to guide farmland fertilisation strategies in yellow loam areas.
