Kisspeptin in the posterodorsal medial amygdala modulates sexual partner preference and anxiety in male mice

Adekunbi Daniel , LI Xiaofeng , Lass Geffen , Adegoke Olufeyi , Yeo Shel , Colledge William , Lightman Stafford , O'Byrne Kevin

The posterodorsal medial amygdala (MePD) is a neural site in the limbic brain involved in regulating emotional and sexual behaviours. There is however limited information on the specific neuronal cell type in the MePD functionally mediating these behaviours in rodents. The recent discovery of a significant kisspeptin neurone population in the MePD has raised interest in the possible role of kisspeptin and its cognate receptor in sexual be...

Early post-operative morning serum cortisol measurement as a predictor of remission of Cushing's disease

Thoppuram Nithin , Mendoza Nigel , Nair Ramesh , Hatfield Emma , Meeran Karim , Martin Niamh

Background: Determining post-operative remission in Cushing’s disease is challenging. There is no consensus for the post-operative serum cortisol value which reliably predicts remission of Cushing’s disease following trans-sphenoidal surgery. Traditionally, an early post-operative serum cortisol of below 50 nmol/L has been used to predict remission, but achieving this is often at the expense of hypopituitarism.<p class="abst...

Smoke-induced nausea; mediated by the release of the lung tachykinin, endokinin, into the circulation?

Vaiyapuri Sakthi , Kaiser William , Bicknell Anrew , Gibbins Jon , Lowry Philip

Nausea/vomiting induced by smoke inhalation is a common phenomenon, possibly explaining why many people who have a naturally strong reaction rarely take up smoking tobacco. The tachykinins are an ancient family of bioactive peptides distinguished by the common C-terminal motif, Phe-X-Gly-Leu-Met-amide. In humans, there are four members: substance P (SP), endokinin (EK) also known as hemokinin (HK), neurokinin A and neurokinin B, which sig...

Scagliotti Valeria , Gutierrez Lorena Perez , Gualtieri Angelica , Jimenez Fernando , Kirkby Nicholas , Mitchell Jane , Warner Timothy , Gevers Evelien , Dattani Mehul , Gaston-Massuet Carles

Adamantinomatous craniopharyngiomas (ACPs) are among the most common intracranial tumours in children and they originate from undifferentiated pituitary progenitors. Mutations in the gene encoding for β-catenin (CTNNB1), which lead to the constitutive activation of the Wnt/β-catenin signalling pathway, have been associated with ACP. These tumours can invade adjacent structures, such as the hypothalamus, which makes comp...

Copeptin during hypertonic saline infusion in a polyuria/polydipsia syndrome case series

Boot Christopher , James R Andrew , Tsatlidis Vasileios , Gibb Fraser , Green Fiona , Neely R Dermot G

Introduction: Copeptin is the C-terminal fragment of proAVP and provides an alternative measure of AVP secretion. While direct measurement of AVP during hypertonic saline infusion has been recommended as a diagnostic test for diabetes insipidus (DI), the number of reports examining the utility of copeptin in this context is limited. Here we describe a series of cases where measurement of copeptin during saline infusion has contributed to ...

Bilateral Inferior Petrosal Sinus Sampling (BIPSS) reliably differentiates pituitary from ectopic Cushing’s syndrome, but does not predict pituitary tumour location, especially when lateralizing to the right

White Louisa , Tobin Jake , Koulouri Olympia , Powlson Andrew , Bashari Waiel , Koo Brendan , Gurnell Mark

Background: BIPSS is considered the gold-standard procedure for differentiating autonomous pituitary [Cushing’s Disease (CD)] and ectopic ACTH syndrome (EAS) sources of ACTH hypersecretion. A basal (i.e. unstimulated) pituitary:peripheral ACTH ratio >2, and/or a CRH stimulated pituitary:peripheral ACTH ratio >3, have been proposed as indicative of CD, with a range of sensitivities and specificities cited in the literature. Ad...
