The Relationship between institutional, course level and individual teaching excellence in Higher Education: a proposal for developing competitive advantage through leveraging the expertise of excellent university teachers.

Internationally many nations are seeking to recognise and reward excellent teaching at an institutional, subject and individual level, acknowledging the importance of outstanding teaching as a contribution to positive student learning experiences through students’ academic, emotional and transactional engagement. This paper explores the ways in which higher education teaching excellence can be recognised and rewarded, using a case study from the UK, and considers the relationship between institutional, course-level and individual teaching excellence. We conclude by proposing that HEIs can develop a competitive advantage through leveraging the expertise of excellent university teachers to the benefit of learners

Long live FOXO: unraveling the role of FOXO proteins in aging and longevity

Aging constitutes the key risk factor for age-related diseases such as cancer and cardiovascular and neurodegenerative disorders. Human longevity and healthy aging are complex phenotypes influenced by both environmental and genetic factors. The fact that genetic contribution to lifespan strongly increases with greater age provides basis for research on which protective genes are carried by long-lived individuals. Studies have consistently revealed FOXO (Forkhead box O) transcription factors as important determinants in aging and longevity. FOXO proteins represent a subfamily of transcription factors conserved from Caenorhabditis elegans to mammals that act as key regulators of longevity downstream of insulin and insulin-like growth factor signaling. Invertebrate genomes have one FOXO gene, while mammals have four FOXO genes: FOXO1, FOXO3, FOXO4, and FOXO6. In mammals, this subfamily is involved in a wide range of crucial cellular processes regulating stress resistance, metabolism, cell cycle arrest, and apoptosis. Their role in longevity determination is complex and remains to be fully elucidated. Throughout this review, the mechanisms by which FOXO factors contribute to longevity will be discussed in diverse animal models, from Hydra to mammals. Moreover, compelling evidence of FOXOs as contributors for extreme longevity and health span in humans will be addressed

The kainate receptor antagonist UBP310 but not single deletion of GluK1, GluK2, or GluK3 subunits, inhibits MPTP-induced degeneration in the mouse midbrain

© 2019 Elsevier Inc. The excitatory neurotransmitter glutamate is essential in basal ganglia motor circuits and has long been thought to contribute to cell death and degeneration in Parkinson's disease (PD). While previous research has shown a significant role of NMDA and AMPA receptors in both excitotoxicity and PD, the third class of ionotropic glutamate receptors, kainate receptors, have been less well studied. Given the expression of kainate receptor subunits GluK1-GluK3 in key PD-related brain regions, it has been suggested that GluK1-GluK3 may contribute to excitotoxic cell loss. Therefore the neuroprotective potential of the kainate receptor antagonist UBP310 in animal models of PD was investigated in this study. Stereological quantification revealed administration of UBP310 significantly increased survival of dopaminergic and total neuron populations in the substantia nigra pars compacta in the acute MPTP mouse model of PD. In contrast, UBP310 was unable to rescue MPTP-induced loss of dopamine levels or dopamine transporter expression in the striatum. Furthermore, deletion of GluK1, GluK2 or GluK3 had no effect on MPTP or UBP310-mediated effects across all measures. Interestingly, UBP310 did not attenuate cell loss in the midbrain induced by intrastriatal 6-OHDA toxicity. These results indicate UBP310 provides neuroprotection in the midbrain against MPTP neurotoxicity that is not dependent on specific kainate receptor subunits

MNK1 and MNK2 mediate adverse effects of high-fat feeding in distinct ways

The MAP kinase-interacting kinases (MNK1 and MNK2) are non-essential enzymes which are activated by MAP kinases. They are implicated in controlling protein synthesis. Here we show that mice in which the expression of either MNK1 or MNK2 has been knocked out (KO) are protected against adverse effects of high-fat feeding, and in distinct ways. High-fat diet (HFD)-fed MNK2-KO show less weight gain than wild-type animals, and improved glucose tolerance, better insulin sensitivity and markedly diminished adipose tissue inflammation. This suggests MNK2 plays a role in adipogenesis and/or lipogenesis and in macrophage biology. MNK1-KO/HFD mice show better glucose tolerance and insulin sensitivity, but gain weight and show similar adipose inflammation to WT animals. These data suggest MNK1 participates in mediating HFD-induced insulin resistance. Our findings reveal distinct roles for the MNKs in a novel area of disease biology, metabolic dysfunction, and suggests they are potential new targets for managing metabolic disease
