The striatal dopamine transporter in first-episode, drug-naive schizophrenic patients: evaluation by the new SPECT-ligand[99mTc]TRODAT-1 [PDF]

, 2005
Following the current hypothesis that acute schizophrenic psychotic illness is associated with a triatal ‘hyperdopaminergic state’, presynaptic integrity and dopamine transporter (DAT) density in first-episode, neuroleptic-naive schizophrenic patients ...

A Multi‐Institutional Retrospective Study of 21 Dogs Having Undergone Hypofractionated Radiotherapy for Adrenal Tumours (2017–2024)

Veterinary and Comparative Oncology, EarlyView.
ABSTRACT Radiation therapy (RT) has emerged as a promising non‐surgical approach for treating canine adrenal tumours. This multi‐institutional, retrospective study describes clinical outcomes for 21 dogs having been prescribed a course of hypofractionated image‐guided intensity‐modulated RT (IMRT) entailing delivery of 25–35 Gy total in 5 fractions ...

Persistent Erythrocytosis in a Dog With a Spinal Sclerosing Paraganglioma

Veterinary Clinical Pathology, EarlyView.
ABSTRACT A 7‐year‐old, male, castrated, mixed‐breed dog presented with right pelvic limb lameness and pain on posturing to defecate that began 1.5 years prior to presentation. Radiographs taken 8 months prior to presentation showed a small lytic lesion of the L6 vertebral body, and CBCs showed a persistently increased hematocrit (HCT) for at least 2 ...

Differential Responses of Urinary Epinephrine and Norepinephrine to 24-h Shift-Work Stressor in Physicians

Frontiers in Endocrinology, 2020
Multiple stressors, including 24-h-shifts characterise the working environment of physicians, influencing well-being, health and performance. We aimed to evaluate the effect of the stressor 24-h-shift on the adrenal medullary and sympathoneural system in

Development and Validation of a Fluoroimmunoassay for Urinary Normetanephrine [PDF]

Annals of Clinical Biochemistry: International Journal of Laboratory Medicine, 1991
The development of a separation fluoriommunoassay for urinary normetanephrine is described. Antiserum specific to normetanephrine was coupled, using cyanogen bromide, to magnetizable cellulose; and fluorescein labelled normetanephrine was synthesized from fluoresceinthiocarbamylethylene diamine and a previously described normetanephrine derivative ...

Natural History and Management of Familial Paraganglioma Syndrome Type 1: Long-Term Data from a Large Family [PDF]

, 2020
Head and neck paragangliomas are the most common clinical features of familial paraganglioma syndrome type 1 caused by succinate dehydrogenase complex subunit D (SDHD) mutation. The clinical management of this syndrome is still unclear.

Seven days of mixed‐method heat acclimation improved markers of cardiovascular and fluid‐regulatory strain during exercise‐heat stress

Experimental Physiology, EarlyView.
Abstract A mixed‐method heat acclimation (HA) protocol may optimise performance by supporting the training taper while promoting thermal adaptation; however, the impact on cardiovascular and fluid‐regulatory adjustments to protect health is unknown. Therefore, we examined the effects of a mixed‐method heat protocol on physiological responses, including

The Importance of Exclusion of Obstructive Sleep Apnea During Screening for Adrenal Adenoma and Diagnosis of Pheochromocytoma

Journal of Investigative Medicine High Impact Case Reports, 2015
Context . As catecholamine elevation is a key element in the diagnosis of pheochromocytoma, more commonplace causes of sympathetic excess, such as obstructive sleep apnea (OSA), should be excluded as standard practice prior to diagnosis.
