Allosteric sensitization of nicotinic receptors by galantamine, a new treatment strategy for Alzheimer’s disease

2001

Cholinesterase inhibitors are the only approved drug treatment for patients with mild to moderately severe Alzheimer's disease. Interestingly, the clinical potency of these drugs does not correlate well with their activity as cholinesterase inhibitors, nor is their action as short lived as would be expected from purely symptomatic treatment. A few cholinesterase inhibitors, including galantamine, produce beneficial effects even after drug treatment has been terminated. These effects assume modes of action other than mere esterase inhibition and are capable of inducing systemic changes. We have recently discovered a mechanism that could account, at least in part, for the above-mentioned unex…

Oxygen and glucose deprivation induces major dysfunction in the somatosensory cortex of the newborn rat

2005

The mechanisms and functional consequences of ischemia-induced injury during perinatal development are poorly understood. Subplate neurons (SPn) play a central role in early cortical development and a pathophysiological impairment of these neurons may have long-term detrimental effects on cortical function. The acute and long-term consequences of combined oxygen and glucose deprivation (OGD) were investigated in SPn and compared with OGD-induced dysfunction of immature layer V pyramidal cortical neurons (PCn) in somatosensory cortical slices from postnatal day (P)0-4 rats. OGD for 50 min followed by a 10-24-h period of normal oxygenation and glucose supply in vitro or in culture led to pron…

A new approach using high volume blood patch for prevention of post-dural puncture headache following intrathecal catheter pump exchange.

2015

Background: In an observational study, complications of intrathecal catheter pumps necessitating surgical exchange were analyzed. Also the use of a high-volume prophylactic epidural blood patch (EBP) during surgery for preventing post-dural puncture headache (PDPH) with a follow-up for 1 year is described. Materials and Methods: In 22 patients with refractory chronic pain of cancer/noncancer origin or severe spasticity, who were receiving intrathecal morphine including adjuvants or baclofen for symptom relief, catheter exchange with or without pump was performed. In patients with documented symptoms of PDPH following initial intrathecal catheter implantation, a prophylactic EBP with a high …

Impact of serotonin 2C receptor null mutation on physiology and behavior associated with nigrostriatal dopamine pathway function.

2009

The impact of serotonergic neurotransmission on brain dopaminergic pathways has substantial relevance to many neuropsychiatric disorders. A particularly prominent role has been ascribed to the inhibitory effects of serotonin 2C receptor (5-HT2CR) activation on physiology and behavior mediated by the mesolimbic dopaminergic pathway, particularly in the terminal region of the nucleus accumbens. The influence of this receptor subtype on functions mediated by the nigrostriatal dopaminergic pathway is less clear. Here we report that a null mutation eliminating expression of 5-HT2CRs produces marked alterations in the activity and functional output of this pathway. 5-HT2CR mutant mice displayed i…

The Interplay between Magnesium and Testosterone in Modulating Physical Function in Men

2014

The role of nutritional status as determinant of successful aging is very well recognized. There is recent evidence that nutrition may exert its beneficial effects through the modulation of the hormonal anabolic milieu. Under-nutrition and anabolic hormonal deficiency frequently coexist in older individuals determining an increased risk of mobility impairment and adverse outcomes. Mineral dietary assessment has received attention as key component of the nutritional modulation of anabolic status and physical performance. There is evidence that several minerals, including magnesium, exert a positive influence on Insulin-like Growth Factor-1 (IGF-1) secretion in both sexes, and Testosterone (T…

The effects of transdermal testosterone and oestrogen therapy on dry eye in postmenopausal women: a randomised, placebo-controlled, pilot study

2016

Aims Sex hormones could provide a future treatment avenue for dry eye post menopause. However, there are few well-controlled studies. This study investigates the impact of testosterone and oestrogen on dry eye symptoms and signs in postmenopausal women. Methods A randomised double-blind placebo-controlled pilot study was conducted involving 40 women with dry eye (age 63.9±5.1 years, 13.2±6.3 years post menopause). Ten women were assigned to each of four treatment groups: transdermal testosterone, oestradiol, testosterone/oestradiol combination and placebo. Assessment at baseline and after 8 weeks: ocular symptoms, tear osmolarity, tear stability, tear secretion, meibomian gland assessment, …

Trichoscopy features of trichotillomania

2019

Trichotillomania is a form of traction alopecia resulting from repetitive and compulsive hair pulling and plucking. Trichotillomania and patchy alopecia areata may have similar clinical and dermoscopic features in some cases. On trichoscopic examination, the presence of black dots, coiled or hook hair, shafts of varying lengths with fraying or split ends (trichoptilosis), and an absence of exclamation mark hairs and yellow dots are suggestive of trichotillomania.
