Inhibiting cholinergic signalling in the cerebellar interpositus nucleus impairs motor behaviour.

The role of neuromodulators in the cerebellum is not well understood. In particular, the behavioural significance of the cholinergic system in the cerebellum is unknown. To investigate the importance of cerebellar cholinergic signalling in behaviour, we infused acetylcholine receptor antagonists, scopolamine and mecamylamine, bilaterally into the rat cerebellum (centred on interpositus nucleus) and observed the motor effects through a battery of behavioural tests.

Cerebellar Prediction and Feeding Behaviour.

Given the importance of the cerebellum in controlling movements, it might be expected that its main role in eating would be the control of motor elements such as chewing and swallowing. Whilst such functions are clearly important, there is more to eating than these actions, and more to the cerebellum than motor control. This review will present evidence that the cerebellum contributes to homeostatic, motor, rewarding and affective aspects of food consumption.

Cerebellar modulation of memory encoding in the periaqueductal grey and fear behaviour.

The pivotal role of the periaqueductal grey (PAG) in fear learning is reinforced by the identification of neurons in male rat ventrolateral PAG (vlPAG) that encode fear memory through signalling the onset and offset of an auditory-conditioned stimulus during presentation of the unreinforced conditioned tone (CS+) during retrieval. Some units only display CS+ onset or offset responses, and the two signals differ in extinction sensitivity, suggesting that they are independent of each other. In addition, understanding cerebellar contributions to survival circuits is advanced by the discovery that (i) reversible inactivation of the medial cerebellar nucleus (MCN) during fear consolidation leads in subsequent retrieval to (a) disruption of the temporal precision of vlPAG offset, but not onset responses to CS+, and (b) an increase in duration of freezing behaviour.

Use of telemedicine for ichthyosis: Patient advocacy group as conduit to expert physician advice.

Background/objectives: Patients with rare diseases are challenged when it comes to finding physicians with expertise in their condition. The Foundation for Ichthyosis and Related Skin Types (FIRST) Tele-Ichthyosis program has provided telemedicine for patients and their families with keratinizing disorders since 2009. This study aims to characterize a decade of experience with the program.

Use of unmanned aerial vehicles (UAVs) for mark-resight nesting population estimation of adult female green sea turtles at Raine Island.

Nester abundance is a key measure of the performance of the world's largest green turtle rookery at Raine Island, Australia, and has been estimated by mark-resight counts since 1984. Nesters are first marked by painting their carapace with a longitudinal white stripe. Painted and unpainted turtles are then counted by a surface observer on a small boat in waters adjacent to the reef.

Second round results from the Manchester 'Lung Health Check' community-based targeted lung cancer screening pilot.

We report results from the second annual screening round (T1) of Manchester's 'Lung Health Check' pilot of community-based lung cancer screening in deprived areas (undertaken June to August 2017). Screening adherence was 90% (n=1194/1323): 92% of CT scans were classified negative, 6% indeterminate and 2.5% positive; there were no interval cancers.

Muscarinic Receptor Modulation of the Cerebellar Interpositus Nucleus In Vitro.

How the cerebellum carries out its functions is not clear, even for its established roles in motor control. In particular, little is known about how the cerebellar nuclei (CN) integrate their synaptic and neuromodulatory inputs to generate cerebellar output. CN neurons receive inhibitory inputs from Purkinje cells, excitatory inputs from mossy fibre and climbing fibre collaterals, as well as a variety of neuromodulatory inputs, including cholinergic inputs.

Implementing lung cancer screening: baseline results from a community-based 'Lung Health Check' pilot in deprived areas of Manchester.

We report baseline results of a community-based, targeted, low-dose CT (LDCT) lung cancer screening pilot in deprived areas of Manchester. Ever smokers, aged 55-74 years, were invited to 'lung health checks' (LHCs) next to local shopping centres, with immediate access to LDCT for those at high risk (6-year risk ≥1.51%, PLCO calculator).

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.

Elongation factor 2 kinase promotes cell survival by inhibiting protein synthesis without inducing autophagy.

Eukaryotic elongation factor 2 kinase (eEF2K) inhibits the elongation stage of protein synthesis by phosphorylating its only known substrate, eEF2. eEF2K is tightly regulated by nutrient-sensitive signalling pathways. For example, it is inhibited by signalling through mammalian target of rapamycin complex 1 (mTORC1).

NHS Health Checks in a primary care dental setting - an opportunity for the profession to maximise uptake for public health partners?

This opinion piece considers an opportunity for primary dental care practitioners to work in partnership with public health teams to maximise the uptake of the NHS Health Check. Public Health England and Local Authority partners remain committed to offering the NHS Health Check to those aged 40-74 years old. The programme previously explored alternative points of delivery - such as community pharmacists.

Postnatal dynamics of Zeb2 expression in rat brain: analysis of novel 3' UTR sequence reveals a miR-9 interacting site.

ZEB2 is a transcription factor with established roles in neurogenesis but no defined function in postnatal brain despite extensive neuronal expression in telencephalic structures. Multiple, incompletely annotated transcripts derive from the Zeb2 locus; the purpose of the present study was to structurally characterize rat brain Zeb2 transcripts with respect to 3' untranslated (UTR) sequence in order to understand Zeb2 transcript regulation including possible interactions with regulatory molecules such as neuronal miRNAs. We cloned a 5054-nucleotide Zeb2 3' UTR that is included in the most abundant Zeb2 transcript in neonatal rat brain.

Robot-assisted laparoscopic prostatectomy: a 2010 update.

Aim: To build on the previous article and further explore the safety and efficacy of robotic-assisted laparoscopic prostatectomy (RALP) in the first 100 cases from a single institution in New Zealand.

Method: A prospective database was created to monitor perioperative and postoperative outcomes of men undergoing RALP for clinically localised carcinoma of the prostate.

Results: The first 100 cases were followed prospectively with a mean follow-up of 13.
