Judith Sergeant, Rosemary Rizq
This study explores the impact of menopause on women's identity and considers the effect of sociocultural factors on their experience of this stage of life. Semi-structured interviews were conducted with 11 women and analysed following constructivist Grounded Theory methods. Women described uncertainty produced by their changing bodies. Menopause was interpreted as marking transition to another phase of life, which necessitated renegotiation of role and status in the face of menopause narratives questioning women's relevance, vigour, attractiveness and emotional stability...

Phosphorus is an important nutrient for crop productivity. More than 60% of the total phosphorus in cereal crops is finally allocated into the grains and is therefore removed at harvest. This removal accounts for 85% of the phosphorus fertilizers applied to the field each year. However, because humans and non-ruminants such as poultry, swine and fish cannot digest phytate, the major form of phosphorus in the grains, the excreted phosphorus causes eutrophication of waterways. A reduction in phosphorus accumulation in the grain would contribute to sustainable and environmentally friendly agriculture...

Abiotic stresses limit crop growth and productivity worldwide. Cellular tolerance, an important abiotic stress adaptive trait, involves coordinated activities of multiple proteins linked to signalling cascades, transcriptional regulation and other diverse processes. Basal transcriptional machinery is considered to be critical for maintaining transcription under stressful conditions. From this context, discovery of novel basal transcription regulators from stress adapted crops like peanut would be useful for improving tolerance of sensitive plant types...

BACKGROUND: This study investigated the potassium (K) levels in petiole and other grape tissues during ripening in Vitis vinifera Shiraz and Cabernet Sauvignon, grown in areas with differences in vigour, and with and without leaf thinning. K in petiole, seeds, skin and flesh were related to grape pH, acidity, berry weight and total soluble solids. RESULTS: Differences in K levels in petiole were in accordance with the differences in soil K. Leaf thinning gave rise to higher K levels in petiole but in grape tissues the differences were not significant in all samplings with greater differences at the end of the growing cycle...

Transporter genes and cytokinins are key targets for crop improvement. These genes are active during the development of the seed and its establishment as a strong sink. However, during germination, the seed transitions to being a source for the developing root and shoot. To determine if the sucrose transporter (SUT), amino acid permease (AAP), Sugar Will Eventually be Exported Transporter (SWEET), cell wall invertase (CWINV), cytokinin biosynthesis (IPT), activation (LOG) and degradation (CKX) gene family members are involved in both the sink and source activities of seeds, we used RT-qPCR to determine the expression of multiple gene family members, and LC-MS/MS to ascertain endogenous cytokinin levels in germinating Pisum sativum L...

BACKGROUND: Attracted by their high economic growth rates, young and growing populations, and increasingly open markets, transnational food and beverage corporations (TFBCs) are targeting Asian markets with vigour. Simultaneously the consumption of ultra-processed foods high in fat, salt and glycaemic load is increasing in the region. Evidence demonstrates that TFBCs can leverage their market power to shape food systems in ways that alter the availability, price, nutritional quality, desirability and ultimately consumption of such foods...

Hybrids between the Arabidopsis ecotypes C24 and Ler have high levels of hybrid vigour, heterosis, in both biomass and seed yield. Heterosis can be detected throughout the development of the plant and in different tissues. We examined developing embryos and seeds of C24/Ler reciprocal hybrids with the aim of detecting the earliest time at which heterotic gene activity occurs. In the transcriptomes of 4 dap (dermatogen to globular) and 6 dap (heart) embryos from both parents and hybrids, 95% of expressed genes were at the Mid Parent Value (MPV) and 95% of the genes with SNPs between C24 and Ler retained the same relative allelic expression levels in the hybrids as existed in the parents...

The objective of this study was to evaluate the effects of vitamin C on growth and quality of semen from Oreochromis niloticus breeders. One hundred and sixty males were fed with different levels of vitamin C (0, 261, 599 and 942 mg/kg diet). The higher weight values were recorded for 599 (166 g) and 942 (175 g) mg of vitamin C/kg diet. Sperm motility, vigour and concentration were higher with 599 and 942 mg of vitamin C/kg diet. The semen volume, gonadosomatic index and plasma protein data from the last week showed a direct relationship with increasing levels of vitamin C...

The basal ganglia are known to be involved in the planning, execution and control of gripping force and movement vigour. Here we aim to define the nature of the basal ganglia control signal for force and to decode gripping force based on local field potential (LFP) activities recorded from the subthalamic nucleus (STN) in patients with deep brain stimulation (DBS) electrodes. We found that STN LFP activities in the gamma (55-90 Hz) and beta (13-30m Hz) bands were most informative about gripping force, and that a first order dynamic linear model with these STN LFP features as inputs can be used to decode the temporal profile of gripping force...

INTRODUCTION: The selection of a sperm with good genomic integrity is an important consideration for improving intracytoplasmic sperm injection (ICSI) outcome. Current convention selects sperm by vigour and morphology, but preliminary evidence suggests selection based on hyaluronic acid binding may be beneficial. The aim of the Hyaluronic Acid Binding Sperm Selection (HABSelect) trial is to determine the efficacy of hyaluronic acid (HA)-selection of sperm versus conventionally selected sperm prior to ICSI on live birth rate (LBR)...

The main goal of this study was to examine the relationship among burnout, engagement, well-being, and academic performance in Portuguese secondary school pupils. The existence of gender related differences in these relationships was also investigated. The sample was composed of 489 pupils who attended an academic track at secondary school. Results of multi-group structural equation modelling indicated that higher levels of cynicism towards studies were associated with lower academic achievement. Exhaustion was not uniquely related to the adolescents' academic achievement or well-being...

Climate shifts at decadal scales can have environmental consequences, and therefore, identifying areas that act as environmental refugia is valuable in understanding future climate variability. Here we illustrate how, given appropriate geohydrology, a rift basin and its catchment can buffer vegetation response to climate signals on decadal time-scales, therefore exerting strong local environmental control. We use time-series data derived from Normalised Difference Vegetation Index (NDVI) residuals that record vegetation vigour, extracted from a decadal span of MODIS images, to demonstrate hydrogeological buffering...

Lead (Pb) poisoning via ingestion of shot pellets is a frequent cause of death in wild birds and also has a wide range of subclinical effects. Here we report on the sublethal effects Pb exposure has on the breeding performance of red-legged partridges (Alectoris rufa). We studied the effects of Pb exposure on sperm quality, reproductive success, egg properties, laying performance, antioxidant levels, and carotenoid-based coloration. Birds were exposed by oral gavage to one or three No. 6 Pb shot pellets (2...

The structure of compacted soils is characterised by decreased (macro-)porosity, which leads to increased mechanical impedance and decreased fluid transport rates, resulting in reduced root growth and crop productivity. Particularly in soils with high mechanical impedance, macropores can be used by roots as pathways of least resistance. This study investigated how different soil physical states relate to whole plant growth and whether roots grow towards spots with favourable soil physical conditions. Experiments were conducted under controlled and field conditions...

With the advent of long-term athlete development programs and early sport specialization, the training of elite athletes now spans the period of adolescence. Adolescence represents a period of physical, psychosocial and cognitive development, but also a time of physical and psychological vulnerability. Changes in skeletal and physiological attributes coincide with an increased risk of sport related injury. A window of vulnerability is shaped by the properties of the musculoskeletal system, the influence of pubertal hormones and the lag time between physical and cognitive development...
